CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation of International Application No. PCT/KR2024/012624, filed on Aug. 23, 2024, which is based on and claims priority to Korean Patent Application Nos. 10-2023-0132592, filed on Oct. 5, 2023, and 10-2023-0146938, filed on Oct. 30, 2023, in the Korean Patent Application, the disclosures of which are incorporated by reference herein in their entireties.

BACKGROUND

1. Field

The disclosure relates to a packaging box that may be opened using a ribbon.

2. Description of Related Art

Home appliances or electronic devices such as computers, tablet personal computers (tablet PCs), and smartphones may be stored or distributed in a protected state in packaging boxes suitable for each appliance or device. A packaging box is manufactured in consideration of the size or weight of the product accommodated therein, and may provide stability during loading while protecting the product. Unlike large home appliances, a packaging box for an electronic device with portability (e.g., a smartphone) may be manufactured in consideration of not only protection or loading of the electronic device but also user appeal, and may have an appearance that reveals the specifications or characteristics of the packaged product. For example, a packaging box for an expensive and downsized electronic device may be provided to increase the consumer satisfaction or desire for ownership. Therefore, packaging boxes with different appearances may be provided according to various electronic device manufacturers, or according to the packaged product.

The above-described information is provided as related art for the purpose of helping understanding of the disclosure. No assertion or determination is made as to whether any of the above-described content may be applied as prior art in relation to the disclosure.

DETAILED DESCRIPTION

A packaging box may generally illustrate the external characteristics or performance of a product accommodated therein through visual information such as material, color, and printed designs on the exterior. However, this is something that a user may sufficiently obtain through prior information, and there may be limitations in providing information about the structure of a product that may be deformed in a portable state and an actual use state through the packaging box. For example, there may be limitations in providing the deformable appearance structure of an electronic device such as a foldable-type smartphone or laptop computer through the packaging box.

An embodiment of the disclosure is intended to at least solve the above-described problems and disadvantages and to provide at least the advantages described below, and may provide a packaging box that additionally guides information about the appearance structure of an accommodated product in the process of opening the product packaging.

An embodiment of the disclosure may provide a packaging box including an opening ribbon that may provide various user experiences in opening the product packaging.

An embodiment of the disclosure may provide a packaging box configured to operate complex opening operations while enhancing user convenience with a simple operation.

The technical objects to be achieved in this document are not limited to the technical problems mentioned above, and other technical objects not mentioned may be clearly understood by those skilled in the art to which the disclosure belongs from the description below.

The following description of the accompanying drawings may provide an understanding of various example implementations of the disclosure including the claims and their corresponding contents. The specific embodiments disclosed in the following description entail various specific details to aid understanding, but are regarded as one of various embodiments. Accordingly, it will be understood by those skilled in the art that various changes and modifications may be made to the various implementations described in the disclosure without departing from the scope and spirit of the disclosure. Further, descriptions of well-known functions and configurations may be omitted for clarity and conciseness.

The terms and words used in the following description and claims are not limited to the bibliographical meaning, but may be used to clearly and consistently describe an embodiment of the disclosure. Therefore, it will be apparent to those skilled in the art that the following description of various implementations of the disclosure is provided only for the purpose of description, and not for the purpose of limiting the disclosure.

It should be understood that the singular forms “a”, “an”, and “the” include plural meanings unless the context clearly indicates otherwise. Thus, as an example, “a component surface” may be interpreted as including one or more of the surfaces of a component.

The embodiments of the disclosure and the terms used therein are not intended to limit the technical features described in this document to specific embodiments, but should be understood to include various modifications, equivalents, or substitutes of the corresponding embodiment. In connection to the description of the drawings, similar reference numerals may be used for similar or related components. It is to be understood that a singular form of a noun corresponding to an item may include one or more of the things, unless the relevant context clearly indicates otherwise. In this document, phrases such as “A or B”, “at least one of A and B”, “at least one of A or B”, “A, B or C”, “at least one of A, B and C”, and “at least one of A, B, or C” may each include any one of the items listed together in the corresponding phrase, or all possible combinations thereof. As used herein, such terms as “1st” and “2nd,” or “first” and “second” may be used to simply distinguish a corresponding component from another, and does not limit the components in other aspect (e.g., importance or order). It is to be understood that if an element (e.g., a first element) is referred to, with or without the term “operatively” or “communicatively”, as “coupled with,” “coupled to,” “connected with,” or “connected to” another element (e.g., a second element), it means that the element may be coupled with the other element directly (e.g., wiredly), wirelessly, or via a third element.

In the following detailed description, a length direction, a width direction and a thickness direction of an electronic device or a packaging box may be mentioned, where the length direction may be defined as “Y-axis direction”, the width direction as “X-axis direction”, and the thickness direction as “Z-axis direction”. In an embodiment, regarding the direction that a component faces, “negative/positive (−/+)” may be mentioned together with the orthogonal coordinate system illustrated in the drawings. For example, a front surface of an electronic device and a packaging box may be defined as “a surface facing the +Z direction”, and a rear surface may be defined as “a surface facing the −Z direction”. In an embodiment, a side surface of an electronic device and a packaging box may include a region facing the +X direction, a region facing the +Y direction, a region facing the −X direction and a region facing the −Y direction. In an embodiment, “X-axis direction” may mean including both “−X direction” and “+X direction”. This is based on the orthogonal coordinate system described in the drawings for conciseness of description, and descriptions of these directions or components do not limit the embodiments of the disclosure. For example, the orthogonal coordinate system may be defined differently from the disclosure according to design specifications of an electronic device and a packaging box or user habits.

FIG. 1 is a perspective view illustrating a packaging box 100 according to an embodiment of the disclosure. FIG. 2 is a perspective view illustrating an opened state of the packaging box 100 of FIG. 1 according to an embodiment of the disclosure. FIG. 3 is an exploded perspective view illustrating the packaging box 100 of FIG. 1 according to an embodiment of the disclosure.

Referring to FIGS. 1 to 3, a packaging box 100 may include a case 101, at least one cover member 102 (e.g., cover members 102a and 102b), a ribbon 103, and a guide member 104 (e.g., the guide member 104 of FIG. 3). The ribbon 103 may have one end portion (e.g., the first end portion 131) connected to the cover member 102 and another end portion (e.g., the second end portion 133) exposed to the outside of the case 101 via the inside of the case 101 and the guide member 104. In an embodiment, a user may pull the second end portion 133 of the ribbon 103 in a direction away from the case 101, and as the ribbon 103 is pulled, the at least one cover member 102 may open the upper portion of the case 101. For example, the at least one cover member 102 may cover or uncover (i.e., close or open) the upper portion of the case 101. In an embodiment, the at least one cover member 102 may be coupled to a first side wall 113a of the case 101 to uncover and cover at least a portion of the first side wall 113a, and may uncover and cover a portion of a second side wall 113b different from the first side wall 113a. For example, the second side wall 113b may be connected (e.g., directly connected) to the first side wall 113a.

According to an embodiment, the case 101 may have a structure with an open upper portion and may provide a space for receiving or storing a smartphone or a tablet PC. However, the embodiments of the disclosure are not limited thereto, and a dummy cover such as a sheet, film and plate may be provided on the upper portion of the case 101 separately from the at least one cover member 102 to uncover and cover the upper portion of the case 101. In the illustrated embodiment, the at least one cover member 102 may include a first cover member 102a and a second cover member 102b disposed symmetrically to each other on the case 101.

According to an embodiment, the case 101 may include a polygonal bottom plate 111, and side walls 113a and 113b extending from edge portions of the bottom plate 111. In an embodiment, when defining that the bottom plate 111 is disposed parallel to the XY plane, the side walls 113a 113b may extend along a direction intersecting the XY plane (e.g., Z-axis direction). In an embodiment, when the bottom plate 111 is manufactured in a rectangular shape, the side walls 113a and 113b may be referred to as first side walls 113a parallel to the YZ plane and second side walls 113b parallel to the XZ plane. Upper end portions of the side walls 113a and 113b, e.g., end portions of the side walls 113a and 113b disposed facing the +Z direction on the case 101, may be disposed to define the open upper portion or open upper surface of the case 101, and the cover members 102 may uncover and cover (close or open) the open upper surface of the case 101. As will be described below, some of the side walls 113a and 113b may provide operation holes 115a and 115b through which the ribbon 103 may be introduced (or guided) into the inside of the case 101 or drawn out to the outside of the case 101. These operation holes 115a and 115b may be at least partially formed by a notch or recess formed in a portion of the side walls 113a and 113b and a portion of the bottom plate 111. In an embodiment, the packaging box 100 may include first operation holes 115a provided in the first side walls 113a and a second operation hole 115b provided in the second side wall 113b.

According to an embodiment, the cover members 102 may be rotatably (or pivotally) coupled to any one of the first side walls 113a. In the illustrated embodiment, the cover members 102 may be rotatably coupled to any one of the first side walls 113a. When the first cover member 102a and the second cover member 102b are provided, the first cover member 102a may be coupled to one side of the case 101 (e.g., one of the first side walls 113a), and the second cover member 102b may be rotatably coupled to another side of the case 101 (e.g., another one of the first side walls 113a). In an embodiment, the cover members 102 may rotate by about 90 degrees from a position closing the upper surface of the case 101. In an embodiment, when there is no interference in the external environment, the cover members 102 may rotate by about 270 degrees from a position closing the upper surface of the case 101. The rotation angle range of such cover members may be appropriately adjusted according to the shape of the case 101 and the cover members 102 or the surrounding environment. In an embodiment, when the packaging box 100 includes the first cover member 102a and the second cover member 102b, the shape, the arrangement and the operation of the first cover member 102a and the second cover member 102b may be substantially symmetrical about the case 101.

According to an embodiment, the packaging box 100 and the cover members 102 may further include an inner cover 129. The inner cover 129 may be disposed, e.g., on the inner surface of the cover members 102, may be disposed substantially parallel to the inner surface of the cover members 102 when the upper portion of the case 101 is closed, and may be disposed inclined with respect to the inner surface of the cover members 102 when the upper portion of the case 101 is covered or open. In an embodiment, the inner cover 129 may conceal a connection portion or adhesion portion between the ribbon 103 and the cover members 102.

According to an embodiment, the guide member 104 may be disposed on the case 101 (e.g., the bottom plate 111). Inside the case 101, a portion of the ribbon 103 from the guide member 104 toward the first end portion 131 may be disposed or aligned substantially along a first direction (e.g., X-axis direction), and another portion of the ribbon 103 from the guide member 104 toward the second end portion 133 may be disposed or aligned along a second direction (e.g., Y-axis direction) intersecting the first direction. A portion of the ribbon 103 aligned along the first direction may be drawn out to the outside of the case 101 through the first side walls 113a via the first operation hole 115a, and the first end portion 131 may be connected to the cover members 102. For example, outside the case 101, the ribbon 103 may be partially disposed between the first side wall 113a and the at least one cover member 102 and may be introduced (or guided) into the inside of the case 101 through the first side wall 113a. In an embodiment, inside the case 101, a portion of the ribbon 103 may be aligned along the first direction (e.g., X-axis direction) in a section between the first side wall 113a and the guide member 104.

According to an embodiment, another portion of the ribbon 103 aligned along the second direction (e.g., Y-axis direction) may be exposed to the outside of the case 101 through one of the second side walls 113b via the second operation hole 115b. For example, a portion of the ribbon 103 may be aligned along the first direction, and as the ribbon 103 passes through the guide member 104, another portion of the ribbon 103 may be aligned in the second direction. As in the illustrated embodiment, in a structure in which the first cover member 102a and the second cover member 102b are provided, the ribbon 103 may be formed with a Y-shaped branch structure. For example, the ribbon 103 may include two first end portions 131 and one second end portion 133. In an embodiment, two opposite end portions of the ribbon 103 may implement the first end portions 131, and a middle portion of the ribbon 103 may be folded to implement the second end portion 133, thereby having a Y-shaped branch structure.

According to an embodiment, after being drawn out to the outside of the case 101 through the first side wall 113a, the ribbon 103 may pass through a gap between the first side walls 113a and the cover members 102 and may be aligned in a direction intersecting the second direction across the inner surface of the cover member 102. In an embodiment, when the case 101 is in a closed state, at least a portion of the ribbon 103 may be disposed adjacent to and substantially parallel to the inner surface of the cover members 102. For example, when the case 101 is in the closed state, a portion of the ribbon 103 located at the upper portion of the case 101 may be disposed substantially parallel to the first direction (e.g., X-axis direction). In an embodiment, the first end portion 131 of the ribbon 103 may be connected or attached to an edge portion of the inner surface of the cover members 102, so that when the case 101 is closed, the ribbon 103 at the upper portion of the case 101 may be disposed across the inner surface of the cover members 102 along a direction substantially parallel to the first direction.

According to an embodiment, the cover members 102 may be coupled adjacent to an edge portion formed by the connection of the first side walls 113a and the bottom plate 111. In an embodiment, the ribbon 103 may be drawn out to the outside of the case 101 or introduced (or guided) into the inside of the case 101 through the first side wall 113a at a position adjacent to the edge portion formed by the first side walls 113a and the bottom plate 111. Thus, when the upper portion of the case 101 is in the closed state, the ribbon 103 may be disposed substantially parallel to a gap between the first side wall 113a and an inner wall surface of the case 101 and to an inner surface of the case 101 at the upper portion of the case 101.

According to an embodiment, the packaging box 100 may receive an electronic device (e.g., the electronic device 10 of FIG. 2 or FIG. 16) such as a smartphone or a tablet PC and its accessory device (e.g., the accessory device 19 of FIG. 16, e.g., a charger and a cable for wired connection). In an embodiment, when a user pulls the second end portion 133 of the ribbon 103 in a state in which the upper portion of the case 101 is closed, the second end portion 133 may gradually move away from the case 101 (e.g., the second side wall 113b). As the second end portion 133 moves away from the second side wall 113b, the ribbon 103 may be aligned away from or inclined with respect to the inner surface of the cover members 102 while the first end portion 131 moves in a direction approaching the first operation hole 115a among the operation holes 115a and 115b. For example, the ribbon 103 may be in a state of contacting or being supported on the upper end portion of the first side wall 113a. As the ribbon 103 is aligned away from or inclined with respect to the inner surface of the cover members 102, it may rotate the cover members 102 in a direction of opening the case 101. Thus, a user may execute the rotation operation of the cover members 102 by pulling the ribbon 103 (e.g., the second end portion 133). As mentioned earlier, when the first cover member 102a and the second cover member 102b are provided, the first cover member 102a and the second cover member 102b may rotate substantially simultaneously and substantially symmetrically with respect to each other. In a structure in which the cover members 102 are symmetrically disposed, the ribbon 103 may be disposed or aligned in a symmetrical trajectory on the case 101. For example, when a portion of the ribbon 103 is disposed between one of the first side walls 113a and the first cover member 102a, another portion of the ribbon 103 may be disposed between another one of the first side walls 113a and the second cover member 102b.

According to an embodiment, the packaging box 100 may further include an inner packaging material 109. For example, an inner space of the case 101 may be partitioned by the inner packaging material 109 according to the configuration and shape of a product (e.g., the electronic device 10 of FIG. 2 or FIG. 16 or the accessory device 19 of FIG. 16) received or stored in the packaging box 100 (e.g., the case 101). In an embodiment, the inner packaging material 109 may include a middle box 191 separating a space where the ribbon 103 is disposed from other spaces inside the case 101, an inner box 193 disposed on an upper portion of the middle box 191, and a pulp tray 195 implementing a space where a product is to be received. In an embodiment, the pulp tray 195 may be supported by the inner box 193 inside the case 101 and disposed or fixed at a designated position.

According to an embodiment, the inner box 193 and the middle box 191 may be formed as a single body, or the middle box 191 and the pulp tray 195 may be formed as a single body. In an embodiment, the inner box 193, the middle box 191 and the pulp tray 195 may be formed as a single body. For example, the inner packaging material 109 may be variously formed according to manufacturing specifications of the packaging box 100 or a product to be received or stored, and is not limited to the illustrated embodiment. In an embodiment, when provided as a structure separating a space where the ribbon 103 is disposed from other spaces, the inner packaging material 109 and the middle box 191 may provide dummy grooves 191a and 191b corresponding to the operation holes 115a and 115b. The dummy grooves 191a and 191b, together with the operation holes 115a and 115b, may implement a passage through which the ribbon 103 may be introduced (or drawn out) into the inside of the case 101.

According to an embodiment, the guide member 104 may be capable of linear reciprocating motion on the bottom plate 111 according to movement of the second end portion 133 of the ribbon 103. In a structure in which the guide member 104 is capable of linear reciprocating motion, the packaging box 100 may further include an elastic member 105 (e.g., a leaf spring) and guide rails 106. When a user pulls the second end portion 133, the guide member 104 may move in a direction in which the second end portion 133 is pulled (e.g., the second direction or-Y direction) while being supported by the elastic member 105, thereby approaching the second side wall 113b adjacent to the second end portion 133. In an embodiment, as the guide member 104 moves, the elastic member 105 deforms and accumulates elastic force and, when there is no external force applied to the second end portion 133 (e.g., user's pulling action), the elastic force accumulated in the elastic member 105 may return the guide member 104 to a position before the second end portion 133 was pulled. In the illustrated embodiment, a structure is illustrated where the elastic member 105 is disposed between the second side wall 113b through which the second end portion 133 passes and the guide member 104, but embodiments of the disclosure are not limited thereto. For example, the elastic member 105 may be disposed between the second side wall 113b through which the second end portion 133 does not pass and the guide member 104 without overlapping the ribbon 103.

According to an embodiment, the guide rails 106 may be disposed on the bottom plate 111 inside the case 101 and may guide linear reciprocating motion of the guide member 104. In an embodiment, the guide rails 106 may guide or force the elastic member 105 to deform into a designated shape when the second end portion 133 is pulled. In an embodiment, when no external force is applied, the guide rails 106 may guide or force the elastic member 105 to restore to an initial shape.

FIG. 4 is an exploded perspective view illustrating the guide member 104 of the packaging box 100 of FIG. 1 according to an embodiment of the disclosure. FIG. 5 is a plan view illustrating the guide member 104 of the packaging box 100 of FIG. 1 according to an embodiment of the disclosure.

Further referring to FIGS. 4 and 5, the guide member 104 may include a first guide plate 141 and first support plates 143. According to an embodiment, the guide member 104 (e.g., the first guide plate 141) may provide a first guide hole 145 penetrating through two opposite surfaces thereof. The first guide hole 145 may be formed, e.g., penetrating through the first guide plate 141 and may extend obliquely with respect to the first direction (e.g., X-axis direction). As the ribbon 103 passes through the guide member 104 substantially through the first guide hole 145, inside the case 101, a portion may be aligned in the first direction and another portion may be aligned in the second direction (e.g., Y-axis direction). In an embodiment, in a structure in which the first guide hole 145 is formed inclined at about 45 degrees with respect to the first direction, the second direction may be a direction substantially perpendicular to the first direction.

According to an embodiment, in a structure in which the first cover member 102a and the second cover member 102b are disposed substantially symmetrically, the first guide hole 145 may include a first section 145a and a second section 145b. When defining that the first section 145a is formed inclined at about 45 degrees with respect to the first direction, the second section 145b may be formed inclined at about 135 degrees with respect to the first direction. For example, the first guide hole 145 may include the first section 145a and the second section 145b disposed substantially perpendicular to each other. In an embodiment, the first section 145a and the second section 145b may be disposed symmetrically with respect to the second direction. In an embodiment, when a portion of the ribbon 103 extending from the first end portion 131 connected to the first cover member 102a (e.g., a first operating ribbon 103a of FIG. 8) passes through the guide member 104 via the first section 145a, another portion of the ribbon 103 extending from the first end portion 131 connected to the second cover member 102b (e.g., a second operating ribbon 103b of FIG. 8) may pass through the guide member 104 via the second section 145b. This will be described with reference to FIG. 8.

According to an embodiment, the first support plates 143 may extend in the X-axis direction and may be provided on one surface of the first guide plate 141. In the illustrated embodiment, a pair of first support plates 143 may be attached to two opposite end portions of the first guide plate 141 in the Y-axis direction. Inside the case 101, the guide member 104 may be disposed with the first support plates 143 substantially in contact with the bottom plate 111, and a designated gap may be formed between the first guide plate 141 and the bottom plate 111. For example, the first guide plate 141 may be spaced from the bottom plate 111 by the thickness of the first support plates 143. As will be described below, the first support plates 143 may protrude in the X-axis direction from edge portions of the first guide plate 141 and are disposed in a gap between the bottom plate 111 and the guide rails 106, allowing the guide member 104 to linearly reciprocate in the Y-axis direction while being guided by the guide rails 106.

FIG. 6 is an exploded perspective view illustrating the elastic member 105 of the packaging box 100 of FIG. 1 according to an embodiment of the disclosure. FIG. 7 is a plan view illustrating the elastic member 105 of the packaging box 100 of FIG. 1 according to an embodiment of the disclosure.

Further referring to FIGS. 6 and 7, the elastic member 105 may include a leaf spring 151 providing guide slots 155 at two opposite end portions in the Y-axis direction, and second support plates 153 coupled to two opposite end portions (e.g., two opposite end portions in the Y-axis direction) of the leaf spring 151. One of the second support plates 153 may be supported by the second side wall 113b, and another one of the second support plates 153 may be partially disposed in a gap between the guide rails 106 and the bottom plate 111 while being supported by one of the first support plates 143. In an embodiment, a structure in which the second support plates 153 is disposed in the gap between the guide rails 106 and the bottom plate 111 may be similar to a structure in which the first support plates 143 is disposed. In the illustrated embodiment, when the guide member 104 linearly moves due to external force, the second support plates 153 may approach each other while elastic force accumulates in the leaf spring 151 and, when there is no force pulling the second end portion 133 of the ribbon 103, the elastic force of the leaf spring 151 may return the guide member 104 to an initial position by moving the second support plates 153 apart.

According to an embodiment, as the second support plates 153 are coupled to the leaf spring 151, second guide holes 155a formed by a portion of the guide slots 155 and a portion of the second support plates 153 may be formed. In an embodiment, the second guide holes 155a may be provided to penetrate through the elastic member 105. As will be described below, a portion of the ribbon 103 aligned in the second direction inside the case 101 may pass through the elastic member 105 via the second guide holes 155a. In an embodiment, in a section between the second guide holes 155a, the ribbon 103 may be disposed between the bottom plate 111 and the leaf spring 151. For example, on the elastic member 105, the ribbon 103 may be disposed in a region that does not interfere with deformation of the leaf spring 151.

FIG. 8 is a plan view illustrating an arrangement of the ribbon 103 of the packaging box 100 of FIG. 1 according to an embodiment of the disclosure.

FIG. 8 is a plan view illustrating a state in which the ribbon 103, the guide member 104 and the elastic member 105 are disposed inside the case 101, and may show a state in which the middle box 191 is removed from the case 101. Further referring to FIG. 8, the ribbon 103 may have its alignment direction switched to the first direction and the second direction by the guide member 104, and a portion aligned in the second direction may cross at least a portion of the elastic member 105. In an embodiment, when no external force is applied, the leaf spring 151 may be generally flat-shaped and, when the guide member 104 moves in the second direction (e.g., −Y direction) due to external force, the elastic member 105 may accumulate elastic force as the curvature of the leaf spring 151 gradually increases. However, the embodiments of the disclosure are not limited thereto, and the elastic member 105 may be positioned at the +Y side of the guide member 104. For example, the elastic member 105 may accumulate elastic force as the curvature of the leaf spring 151 decreases when external force is applied.

According to an embodiment, the ribbon 103 may be introduced into the inside of the case 101 through the first side wall 113a, may be aligned along the first direction, e.g., the X-axis direction, and may be partially disposed between the bottom plate 111 and the first guide plate 141. In an embodiment, a gap corresponding to the thickness of the first support plates 143 may be provided between the bottom plate 111 and the first guide plate 141, thereby suppressing friction that may occur in the pulling operation of the ribbon 103. In an embodiment, the ribbon 103 may be aligned in the second direction while passing through the first guide hole 145. A portion of the ribbon 103 aligned in the second direction on the guide member 104 may be disposed facing the bottom plate 111 with the first guide plate 141 therebetween.

According to an embodiment, the ribbon 103 sequentially passes through the second guide holes 155a across the second support plates 153 along the second direction, so that the second end portion 133 may be positioned in the-Y direction relative to the elastic member 105. In an embodiment, the second support plates 153 may be partially disposed between the ribbon 103 and the bottom plate 111, and in a section between the second guide holes 155a, the ribbon 103 may be disposed between the leaf spring 151 and the bottom plate 111. In an embodiment, when the guide member 104 moves in the second direction (e.g., Y-axis direction) and the leaf spring 151 deforms into a shape with greater curvature, a central portion of the leaf spring 151 may move (or deform) in a direction away from the bottom plate 111 or the ribbon 103. When there is no external force applied to the ribbon 103 or the guide member 104, the leaf spring 151 may restore to a shape with smaller curvature or a substantially flat shape, returning the guide member 104 to an initial position and moving the second end portion 133 in a direction approaching the case 101 (e.g., the second side wall 113b).

According to an embodiment, a middle portion of the ribbon 103 may be folded to implement the second end portion 133, and the ribbon 103 may include a first operating ribbon 103a from the second end portion 133 to a portion connected to the first cover member 102a (e.g., one of the first end portions 131) and a second operating ribbon 103b from the second end portion 133 to a portion connected to the second cover member 102b (e.g., another one of the first end portions 131). In a section from the second end portion 133 to the guide member 104, the first operating ribbon 103a and the second operating ribbon 103b may be disposed parallel to each other along the second direction or Y-axis direction. In an embodiment, the first operating ribbon 103a and the second operating ribbon 103b are disposed substantially parallel to the first direction in a section between the guide member 104 and the first side walls 113a, and may be drawn out to the outside of the case 101 through the first side walls 113a.

FIG. 9 is an exploded perspective view illustrating the guide rails 106 of the packaging box 100 of FIG. 1 according to an embodiment of the disclosure. FIG. 10 is a plan view illustrating the guide rails 106 of the packaging box 100 of FIG. 1 according to an embodiment of the disclosure. FIG. 11 is a perspective view illustrating an arrangement of the ribbon 103 of the packaging box 100 of FIG. 1 on the case 101 or the guide rails 106 according to an embodiment of the disclosure. FIG. 12 is a plan view illustrating an arrangement of the ribbon 103 in an open state of the packaging box 100 of FIG. 1 according to an embodiment of the disclosure.

FIGS. 11 and 12 illustrate an arrangement state of the ribbon 103 on the guide rails 106 by illustrating the packaging box 100 with the bottom plate 111 removed. Further referring to FIGS. 9 to 12, the guide rails 106 may be provided as a pair and disposed adjacent to the first side walls 113a, and may guide the guide member 104 to move in the Y-axis direction. In an embodiment, the guide rails 106 may include spacer plates 163a and 163b and a second guide plate 161. The spacer plates 163a and 163b may be attached to the bottom plate 111, and the second guide plate 161 may be disposed at a designated gap from the bottom plate 111 by being attached to the spacer plates 163a and 163b. In an embodiment, the second guide plate 161 may include a first region 167a attached (e.g., directly attached) to the spacer plates 163a and 163b and a second region 167b at least partially disposed to face the bottom plate 111. The second region 167b may be a region where the spacer plates 163a and 163b are not disposed and a portion facing the bottom plate 111. A portion corresponding to the second region 167b among the gaps between the second guide plate 161 and the bottom plate 111 may be substantially an empty space where the spacer plates 163a and 163b are not disposed.

According to an embodiment, the second region 167b where the spacer plates 163a and 163b are not disposed may be provided as a space for disposing a portion of the ribbon 103, or may be provided as a guide groove receiving a portion of the guide member 104 or the elastic member 105. For example, a portion of the guide member 104 (e.g., the first support plates 143) and a portion of the elastic member 105 (e.g., the second support plates 153) may be disposed between the second region 167b and the bottom plate 111. In an embodiment, by the first support plates 143 and the second support plates 153 being received in the gap between the second guide plate 161 and the bottom plate 111, linear reciprocating motion of the guide member 104 may be guided. In an embodiment, by the second support plates 153 being received in the gap between the second guide plate 161 and the bottom plate 111, the elastic member 105 may deform into a designated shape or restore to an initial shape.

According to an embodiment, for arrangement or guidance of the ribbon 103 or the guide member 104, at least one of the spacer plates 163a and 163b may include a first edge portion 165a aligned (or extending) in the first direction, a second edge portion 165b aligned (or extending) in the second direction, and an inclined edge portion 165c connecting the first edge portion 165a to the second edge portion 165b. The inclined edge portion 165c may be aligned (or extended) obliquely with respect to the first direction or the second direction. Such edge portions 165a, 165b, and 165c of the spacer plates 163a and 163b may provide an arrangement (or alignment) space for the ribbon 103 or a movement guide structure for the guide member 104. For example, the first edge portion 165a, the second edge portion 165b and the inclined edge portion 165c may define at least a portion of a guide groove on the guide rail 106.

According to an embodiment, the first edge portion 165a may define a region receiving a portion of the ribbon 103 aligned in the first direction inside the case 101. A portion of the ribbon 103 aligned in the first direction inside the case 101 may include a section adjacent to the first edge portion 165a and a section adjacent to the first guide plate 141. The second edge portion 165b may define a region receiving a portion of the guide member 104 (e.g., the first support plate 143) and a portion of the elastic member 105 (e.g., the second support plates 153). For example, the second edge portion 165b may function as a structure guiding the guide member 104 to linearly reciprocate along the second direction. In an embodiment, when the guide member 104 has a structure that linearly reciprocates, the inclined edge portion 165c may define a space allowing movement or deformation of a portion of the ribbon 103 between the first side wall 113a and the guide member 104. When the guide member 104 is formed with a fixed structure inside the case 101, the inclined edge portion 165c may be omitted. For example, the guide rails 106 provide a space where the ribbon 103 is disposed or a space where the ribbon 103 deforms using the second guide plate 161 (e.g., a portion of the second region 167b), the first edge portion 165a and the inclined edge portion 165c, and may provide a structure guiding linear movement of the guide member 104 using the second guide plate 161 (e.g., another portion of the second region 167b) and the second edge portion 165b.

FIG. 13 is a perspective view illustrating the packaging box 100 of FIG. 1 partially in perspective according to an embodiment of the disclosure. FIG. 14 is a plan view illustrating an arrangement of the ribbon 103 in the packaging box 100 of FIG. 1 according to an embodiment of the disclosure. FIG. 15 is a perspective view illustrating the arrangement of the ribbon 103 in the packaging box 100 of FIG. 1 according to an embodiment of the disclosure. FIG. 16 is a cross-sectional view illustrating a partial section of the packaging box 100 taken along line A-A′ of FIG. 14 according to an embodiment of the disclosure. FIG. 17 is a cross-sectional view illustrating a partial section of the packaging box 100 taken along line B-B′ of FIG. 14 according to an embodiment of the disclosure.

Referring to FIGS. 13 to 17, an alignment state of the ribbon 103 when the upper portion of the case 101 is closed may be examined. In FIGS. 15 and 16, ‘SP1’ illustrate a point on the ribbon 103 supported on the upper end portion of the first side walls 113a, and ‘SP2’ illustrate a point on the ribbon 103 drawn out to the outside of the case 101 through the first side wall 113a or a point contacting (or supported by) the first side wall 113a. When a user pulls the second end portion 133 to open the case 101, the second end portion 133 may be disposed further from the case 101 (e.g., the second side wall 113b) than the position illustrated in FIG. 17, which is examined with reference to FIG. 22. Inside the packaging box 100, as illustrated in FIG. 16, an electronic device 10 and its accessory device 19 may be received or stored.

According to an embodiment, the electronic device 10 may include at least one pair of housings. In an embodiment, the at least one pair of housings may be rotatably coupled between a folded position, where the housings face each other, and an unfolded position by a designated angle. For example, the electronic device 10 may be a type of foldable electronic device deformable between a folded state and an unfolded state. In an embodiment, the electronic device 10 may include a flexible display disposed on the at least one pair of housings. The flexible display may include a folding region disposed in a region between the at least one pair of housings, a first region extending from the folding region and disposed on a first housing of the at least one pair of housings, and a second region extending from the folding region and disposed on a second housing of the at least one pair of housings.

According to an embodiment, when the at least one pair of housings are folded facing each other, the first region and the second region may be disposed facing each other and visually concealed. In an embodiment, when the at least one pair of housings are unfolded by a designated angle, the first region and the second region may be disposed side by side with the folding region therebetween. In an embodiment, when the at least one pair of housings are folded facing each other, the first region and the second region are visually exposed to the outside of the electronic device and, when the at least one pair of housings are unfolded by a designated angle, the first region and the second region may be disposed side by side with the folding region therebetween.

In an embodiment, when the packaging box 100 is for receiving/storing the electronic device, the first cover member 102a may be disposed corresponding to the first region and a portion of the folding region of the flexible display, and the second cover member 102b may be disposed corresponding to the second region and at least another portion of the folding region of the flexible display. For example, when the packaging box 100 is opened, the first cover member 102a may substantially conceal or expose a first portion of the electronic device in an unfolded state (e.g., a portion of the flexible display), and the second cover member 102b may conceal or expose a second portion of the electronic device in the unfolded state (e.g., at least a remaining portion of the flexible display).

According to an embodiment, outside the case 101, the first operating ribbon 103a and the second operating ribbon 103b may reach the first end portions 131 and be attached or fixed to an edge portion of the inner surface of the cover members 102. An alignment shape of the first operating ribbon 103a and the second operating ribbon 103b outside the case 101 may differ according to the uncovered/open state or the covered/closed state. In the closed state of the case 101, the first operating ribbon 103a and the second operating ribbon 103b may be aligned substantially parallel to the first side walls 113a and an inner wall of the cover members 102 and contact the upper end portion of the first side walls 113a. For example, in a section between SP1 and SP2 of FIG. 15 or FIG. 16, the first operating ribbon 103a and the second operating ribbon 103b may be aligned substantially parallel to the first side walls 113a and the inner wall of the cover members 102.

According to an embodiment, when the case 101 is in the closed state, the first operating ribbon 103a and the second operating ribbon 103b may be disposed across the inner surface of the cover members 102 from the upper end (e.g., point SP1) of the first side walls 113a. In an embodiment, the first end portions 131 of the first operating ribbon 103a and the second operating ribbon 103b may be fixed to an edge portion of the inner surface of the cover members 102. When the case 101 is in the closed state, a portion of the first operating ribbon 103a and the second operating ribbon 103b crossing the inner surface of the cover members 102 may be substantially parallel to the first direction (e.g., X-axis direction) at the upper side of the case 101. When the case 101 is closed, in a section between the guide member 104 and the first side wall 113a, the first operating ribbon 103a and the second operating ribbon 103b may be aligned adjacent to the bottom plate 111 and substantially parallel to the first direction (e.g., X-axis direction).

According to an embodiment, when the case 101 is in the closed state and no external force is applied, the elastic member 105 may maintain the guide member 104 at a position away from the second side wall 113b (e.g., the second side wall 113b through which the ribbon 103 passes). For example, the elastic member 105 may suppress the guide member 104 from moving inside the case 101 due to the weight of the guide member 104 according to tilting or stacking state of the packaging box 100. For example, in a structure in which deformation (e.g., movement or deformation in the-Y direction) of a portion of the ribbon 103 (e.g., a portion aligned along the first direction) is allowed by the spacer plates 163a and 163b including the inclined edge portion 165c, the elastic member 105 may suppress movement of the guide member 104 or deformation of the ribbon 103. In an embodiment, movement of the guide member 104 due to the weight of the guide member 104 inside the case 101 may be suppressed by the alignment structure of the ribbon 103. For example, the guide rail 106 or the spacer plates 163a, 163b, e.g., the spacer plate indicated as ‘163b’ may suppress deformation or movement of the ribbon 103 aligned in the first direction and the guide member 104 in the +Y direction in FIG. 14 or FIG. 15. For example, the arrangement of the elastic member 105 and the ribbon 103 alignment structure by the spacer plates 163a and 163b may suppress movement of the guide member 104 in the closed state of the case 101.

FIG. 18 is a perspective view illustrating an opened state of the packaging box 100 of FIG. 1 according to an embodiment of the disclosure. FIG. 19 is a plan view illustrating an arrangement of the ribbon 103 when the packaging box 100 of FIG. 1 is opened according to an embodiment of the disclosure. FIG. 20 is a perspective view illustrating the arrangement of the ribbon 103 when the packaging box 100 of FIG. 1 is opened according to an embodiment of the disclosure. FIG. 21 is a cross-sectional view illustrating a partial section of the packaging box 100 taken along line C-C′ of FIG. 19 according to an embodiment of the disclosure. FIG. 22 is a cross-sectional view illustrating a partial section of the packaging box 100 taken along line D-D′ of FIG. 19 according to an embodiment of the disclosure.

Referring to FIGS. 18 to 22, an operation of opening the upper portion of the case 101 and an alignment state of the ribbon 103 when the upper portion of the case 101 is open is examined.

Referring to FIGS. 18 to 22, the second end portion 133 may be gradually moved away from the case 101 (e.g., the second side wall 113b) by a user. For example, when wanting to open the case 101, a user may pull the second end portion 133. A displacement or distance that the second end portion 133 is moved away from the case 101 by user manipulation may be converted into a movement distance of the guide member 104 and a change in alignment length of the ribbon 103 from the SP2 points of FIG. 15 to the first end portions 131. For example, the displacement of the second end portion 133 may be substantially equal to the sum of the movement distance of the guide member 104 and the change in length of the ribbon 103 outside the case 101. In an embodiment, the movement distance of the guide member 104 according to the displacement of the second end portion 133 may be inversely proportional to an elastic coefficient of the elastic member 105 (e.g., the leaf spring 151), and the change in length of the ribbon 103 (e.g., the alignment length of the ribbon 103 from the SP2 points of FIG. 15 to the first end portions 131) according to the displacement of the second end portion 133 may be proportional to the elastic coefficient of the elastic member 105 (e.g., the leaf spring 151). As the guide member 104 moves in the second direction (e.g., Y-axis direction), the ribbon 103 may be at least partially aligned obliquely to the first direction in a section between the first side wall 113a and the guide member 104.

According to an embodiment, when the second end portion 133 moves away from the second side wall 113b, the ribbon 103 on the inner surface of the cover members 102 may move (or deform) gradually away from or gradually inclined from the inner surface of the cover members 102. For example, as the length from the SP1 point of FIG. 15 to the first end portion 131 gradually decreases, the ribbon 103 may substantially rotate the cover members 102 in a direction of opening the upper portion of the case 101. Thus, a user may rotate the cover members 102 and open the case 101 by pulling the second end portion 133.

A packaging box 100 for receiving or storing a product from the time of manufacturing completion to the time of sale may have a structure in which a user rotates (e.g., directly rotates) the cover members 102 or moves (e.g., directly moves) a portion of the packaging box 100 horizontally or vertically with respect to a cover member to open it. The packaging box 100 according to the embodiments of the disclosure may be opened with a simple operation of pulling the ribbon 103, so user convenience may be enhanced. In an embodiment, by converting a pulling action of the ribbon 103 into a rotation action of the cover members to open the case 101, a new user experience may be provided in opening the packaging box 100. In an embodiment, the packaging box 100 has an opening structure similar to the deformation operation of an electronic device with a structure capable of external deformation, e.g., a foldable-type smartphone or laptop computer, so that information about the operational structure of the received electronic device may be provided to a user when opening the packaging box 100.

The effects obtainable from the disclosure are not limited to the effects mentioned above, and other effects not mentioned is clearly understood by those skilled in the art to which the disclosure belongs from the description of the above-described embodiments.

According to an embodiment of the disclosure, a packaging box (e.g., the packaging box 100 of FIGS. 1 to 3) may include a case (e.g., the case 101 of FIGS. 1 to 3) with an open upper portion, at least one cover member (e.g., the cover member 102, 102a, and 102b of FIGS. 1 to 3) configured to uncover or cover (open or close) a first side wall and the upper portion of the case by being rotatably coupled to the first side wall (e.g., the first side wall 113a of FIG. 3) of the case, a guide member (e.g., the guide member 104 of FIG. 3) disposed on a bottom plate (e.g., the bottom plate 111 of FIG. 3) of the case, and a ribbon (e.g., the ribbon 103 of FIGS. 1 to 3) having a first end (e.g., the first end portion 131 of FIG. 3) connected to the at least one cover member and a second end (e.g., the second end portion 133 of FIG. 3) exposed to an outside of the case from a second side wall (e.g., the second side wall 113b of FIG. 3) of the case connected to the first side wall and disposed to pass through the guide member in an inside of the case. In an embodiment, the ribbon 103 may be partially disposed between the first side wall and the cover member. In an embodiment, the ribbon 103 may be introduced from the first side wall to the inside of the case and aligned on the bottom plate of the case along a first direction (e.g., the X-axis direction of FIGS. 1 to 3) to reach the guide member. In an embodiment, the ribbon 103 may be aligned from the guide member in a second direction (e.g., the Y-axis direction of FIGS. 1 to 3) intersecting the first direction on the bottom plate such that the second end may be drawn out to the outside through the second side wall.

According to an embodiment, the first end may be attached or fixed to an edge portion of an inner surface of the cover member, and the ribbon 103 may be disposed between the first side wall and the cover member by being extended or aligned along a direction intersecting the second direction from the first end.

According to an embodiment, the cover member may be rotatably coupled to a position adjacent to an edge portion formed by the first side wall and the bottom plate.

According to an embodiment, the ribbon 103 may be introduced into the inside of the case through the first side wall at a position adjacent to the edge portion formed by the first side wall and the bottom plate.

According to an embodiment, in a state in which the upper portion of the case is closed, at least a portion of the ribbon 103 aligned adjacent to the inner surface of the cover member may be disposed parallel to the first direction.
