DETAILED DESCRIPTION

Implementations of the application will be further described in detail below with reference to the drawings and embodiments. The following embodiments are intended to explain the application, but are not intended to limit the scope of the application.

Furthermore, terms “first”, “second” and “third” are only for the purpose of descriptions, and cannot be understood as indicating or implying relative importance.

In the descriptions of the embodiments of the application, it should be noted that unless otherwise specified and defined explicitly, terms “communication” and “connection” should be understood in a broad sense, for example, they may be fixed connection, detachable connection, or integral connection; they may be mechanical connection or electrical connection; they may be direct connection, or indirect connection through an intermediate medium. Specific meanings of the above terms in the embodiments of the application may be understood by those of ordinary skill in the art according to specific situations.

In the related art, a container usually includes an accommodation unit configured to accommodate a stick-like cosmetic product, a guide sleeve configured to guide the accommodation unit along an axial direction, and a drive sleeve configured to drive, by way of rotation, the accommodation unit to move along the axial direction. Friction resistance is usually generated by contact between an outer wall of the accommodation unit and an inner wall of the guide sleeve, such that a user has a certain feeling of resistance in a process of driving the accommodation unit. However, due to dimensional errors and geometric errors generated in production processes, too tight or too loose fit between the guide sleeve and the accommodation unit easily occurs, resulting in that friction force between the guide sleeve and the accommodation unit is unstable, such that when the accommodation unit is moved relative to the guide sleeve along the axial direction, there is a situation where requirement of a driving external force of the accommodation unit is unstable, thereby affecting the user's experience.

Based on the above situation, an embodiment of the application provides a container for a cosmetic product 10. With reference to FIG. 1 to FIG. 10, the container 10 includes a drive sleeve 11, a guide sleeve 12, and an accommodation unit 13. The drive sleeve 11 is provided with a transmission component 11a. The guide sleeve 12 is provided with guide grooves 12a extending along an axial direction of the guide sleeve 12. The accommodation unit 13 is arranged within the guide sleeve 12, a side wall of the accommodation unit 13 is arranged at an interval with the guide sleeve 12. Elastic members 13a and protruded components 13e are arranged on the side wall of the accommodation unit 13. The elastic members 13a are in contact with an inner wall of the guide sleeve 12 and in an elastic deformation state. The drive sleeve 11 is sleeved out of the guide sleeve 12, each of the protruded components 13e passes through a respective one of the guide grooves 12a to cooperate with the transmission component 11a, and the drive sleeve 11 drives the accommodation unit 13 to move along the axial direction of the guide sleeve 12 through cooperation between the transmission component 11a and the protruded components 13e.

It should be noted that the container 10 usually also includes an outer cover 14 to protect the cosmetic product.

In some specific embodiments, the cosmetic product is fixed within the accommodation unit 13, and the cosmetic product may be extended out of or retracted into the guide sleeve 12 as it moves along an axial direction of the accommodation unit 13. Furthermore, the outer cover 14 is sleeved out of the drive sleeve 11 and is detachably connected to the drive sleeve 11, and the outer cover 14 and the drive sleeve 11 define a cavity for protecting the cosmetic product together.

It should be noted that the container 10 in the embodiment of the application may have a columnar shape or another shape, which is not limited here.

Exemplarily, the container 10 has a cylindrical shape, a prismatic shape, etc.

The embodiment of the application is described by an example of the container 10 having a cylindrical shape. In general, an axial direction refers to a direction of a central axis of rotation of a cylinder, that is, a direction common to the central axis. A circumferential direction refers to a “direction of circumference”, that is, a direction around the central axis of the cylinder. A radial direction refers to a direction passing through an axis in a radial plane, a direction of a straight line along a diameter or a radius, or a direction of a straight line perpendicular to the axis.

Exemplarily, the container 10 has a cylindrical shape, and is formed by mutually sleeving the outer cover 14, the drive sleeve 11, the guide sleeve 12 and the accommodation unit 13 along the axial direction. Therefore, the axial direction of the guide sleeve 12 is also the axial direction of the accommodation unit 13 and is also an axial direction of the drive sleeve 11, that is, each of these axial directions is an axial direction of the container 10.

Furthermore, the cosmetic product may have a columnar shape or another shape, which is not limited here.

It should be noted that the accommodation unit 13 may be made of an aluminum alloy member, a tin-plated steel member or the like, which is not limited here.

Exemplarily, the accommodation unit 13 is formed by stamping.

The accommodation unit 13 is arranged within the guide sleeve 12, and a side wall of the accommodation unit 13 is arranged at an interval with the guide sleeve 12, that is, there is a clearance fit between the guide sleeve 12 and the accommodation unit 13, such that the inner wall of the guide sleeve 12 is spaced apart from an outer wall 13f of the accommodation unit.

Furthermore, the accommodation unit 13 is in contact with the inner wall of the guide sleeve 12 through the elastic members 13a and is in an elastic deformation state. That is, abutment between the accommodation unit 13 and the guide sleeve 12 is generated only by the elastic members 13a, to generate resistance. Here, the elastic members 13a may absorb geometric error and dimensional error between the guide sleeve 12 and the accommodation unit 13, to improve a situation where too tight or too loose fit between the guide sleeve 12 and the accommodation unit 13 easily occurs due to dimensional errors and geometric errors generated in production processes, such that friction force between the guide sleeve 12 and the accommodation unit 13 is more stable and balanced, and reliability of assembly between the guide sleeve 12 and the accommodation unit 13 is improved, thereby improving the user's experience.

The elastic members 13a and the protruded components 13e are arranged on the side wall of the accommodation unit 13, which means that the elastic members 13a and the protruded components 13e are connected to the side wall of the accommodation unit 13 respectively. At least a part of each of the protruded components 13e is protruded from the outer wall 13f of the accommodation unit, thereby achieving that each of the protruded components 13e passes through a respective one of the guide grooves 12a and cooperates with the transmission component 11a.

A number of the elastic members 13a may be one, two, three, four, five, six, seven, eight, or the like, which is not limited here.

A number of the protruded components 13e may be one, two, three, four, five, six, seven, eight, or the like, which is not limited here.

The elastic members 13a and the protruded components 13e may be arranged at intervals around an outer circumference of the side wall of the accommodation unit 13 respectively.

The elastic members 13a and the protruded components 13e may be uniformly distributed on the outer circumference of the side wall of the accommodation unit 13 respectively.

It should be noted that the elastic members 13a and the accommodation unit 13 may be an integrally molded structure or a split type structure there-between, and the protruded components 13e and the accommodation unit 13 may also be an integrally molded structure or a split type structure there-between, which is not limited here.

Each of the protruded components 13e passes through a respective one of the guide grooves 12a to cooperate with the transmission component 11a, that is, the guide grooves 12a penetrate a side wall of the guide sleeve 12 respectively, and at least a part of each of the protruded components 13e is located in a respective one of the guide grooves 12a, such that a groove wall of the respective one of the guide grooves 12a may limit position of each of the protruded components 13e.

It may be understood that driving the accommodation unit 13 to move along the axial direction of the guide sleeve 12 through cooperation between the transmission component 11a and the protruded components 13e may be similar to a threaded transmission or a screw transmission, to convert a rotary motion into an axial linear motion while transmitting energy and force.

Specifically, the drive sleeve 11 is sleeved out of the guide sleeve 12 and is rotatable relative to a central axis of the guide sleeve 12, that is, the drive sleeve 11 performs a rotary motion. The transmission component 11a is formed of spiral grooves arranged in an inner wall of the drive sleeve 11, and the protruded components 13e pass through the guide grooves 12a respectively and are at least partially located in the spiral grooves respectively. The rotary motion of the drive sleeve 11 drives the accommodation unit 13 through the protruded components 13e, at this time, the protruded components 13e are located in the spiral grooves respectively and have a tendency of spiral motion with an action of force of inclined surfaces of the spiral grooves. Furthermore, since the guide grooves 12a extending along the axial direction limit positions of the protruded components 13e in a circumferential direction respectively, the tendency of spiral motion of the protruded components 13e is converted to motion along the axial direction, such that the accommodation unit 13 moves along the axial direction of the guide sleeve 12.

Exemplarily, one or multiple strip-shaped protrusions are formed on each of the protruded components 13e, and each of the strip-shaped protrusions is located in a respective one of the spiral grooves, to achieve cooperation between the protruded components 13e and the transmission component 11a, thereby increasing areas of the protruded components 13e contacting the transmission component 11a, improving a situation of stress concentration, and improving reliability of cooperation between the protruded components 13e and the transmission component 11a.

In the embodiment of the application, “multiple” means that the number is two or more.

Exemplarily, the container 10 further includes a base, and the accommodation unit 13, the guide sleeve 12 and the drive sleeve 11 may be made of the same metal material, such that it is more convenient for recycling a discarded package, including that it is convenient for recycling a single accommodation unit 13, a single guide sleeve 12, or a single drive sleeve 11. Furthermore, the base may be detachably mounted on the guide sleeve 12, such that it is more convenient for detaching the base, to facilitate classifying and recycling them, or they are directly replaced by a combination of the accommodation unit 13, the guide sleeve 12 and the drive sleeve 11 after they are used, to continue to use the combination.

According to the container for a cosmetic product 10 provided in the embodiment of the application, the side wall of the accommodation unit 13 is arranged at an interval with the guide sleeve 12, and the elastic members 13a are arranged on the side wall of the accommodation unit 13, such that the elastic members 13a are in contact with the inner wall of the guide sleeve 12 and in an elastic deformation state. That is, abutment between the accommodation unit 13 and the guide sleeve 12 is generated only by the elastic members 13a, to generate resistance. Here, the elastic members 13a may absorb geometric error and dimensional error between the guide sleeve 12 and the accommodation unit 13, to improve a situation where too tight or too loose fit between the guide sleeve 12 and the accommodation unit 13 easily occurs due to dimensional errors and geometric errors generated in production processes, such that friction force between the guide sleeve 12 and the accommodation unit 13 is more stable and balanced, and reliability of assembly between the guide sleeve 12 and the accommodation unit 13 is improved, thereby improving the user's experience.

In some embodiments, with reference to FIG. 9 and FIG. 10, at least a part of each of the elastic members 13a is protruded from an outer wall 13f of the accommodation unit.

It should be noted that the entire elastic member 13a may be protruded from the outer wall 13f of the accommodation unit, or a part of the elastic member 13a may be protruded from the outer wall 13f of the accommodation unit.

However, a size of the elastic member 13a protruded from the outer wall 13f of the accommodation unit may be adjusted according to actual requirements.

Exemplarily, in case that the guide sleeve 12 and the outer wall of the accommodation unit 13 have the same size, along a radial direction of the accommodation unit 13: when the elastic member 13a is protruded from the outer wall 13f of the accommodation unit by a larger size, the elastic member 13a is in contact with the inner wall of the guide sleeve 12 and may generate more elastic deformation, such that there is a larger sliding friction force between the elastic member 13a and the guide sleeve 12, and resistance felt by the user when the user rotates the drive sleeve 11 to drive the accommodation unit 13 is larger; on the contrary, when the elastic member 13a is protruded from the outer wall 13f of the accommodation unit by a smaller size, the elastic member 13a generates smaller elastic deformation, such that there is a smaller sliding friction force between the elastic member 13a and the guide sleeve 12, and resistance felt by the user when the user rotates the drive sleeve 11 to drive the accommodation unit 13 is smaller.

Therefore, by making at least a part of each of the elastic members 13a protruded from the outer wall 13f of the accommodation unit, and adjusting the size of the elastic member 13a protruded from the outer wall 13f of the accommodation unit according to actual requirements, flexible adjustment of the sliding friction force between the elastic member 13a and the guide sleeve 12 may be achieved, further improving the user's experience.

In some embodiments, with reference to FIG. 1, FIG. 5, FIG. 6, FIG. 8 to FIG. 10, the accommodation unit 13 includes a first accommodation member 131 and a second accommodation member 132. The second accommodation member 132 is arranged within the first accommodation member 131.

The accommodation unit 13 includes the first accommodation member 131 and the second accommodation member 132, that is, the accommodation unit 13 has a split type design, such that difficulty of producing and manufacturing the accommodation unit 13 may be reduced, and production efficiency may be improved.

The elastic members 13a may be arranged on the first accommodation member 131 or the second accommodation member 132.

It may be understood that the accommodation unit 13 may also be an integrally molded structure, and the integrally molded structure may improve integrity of the accommodation unit 13, while wall thickness of the accommodation unit 13 is thinner, such that more cosmetic products may be placed in the accommodation unit 13, or an overall size of the container 10 may be smaller.

Exemplarily, the elastic members 13a are arranged on the first accommodation member 131 located at an outer side of the accommodation unit 13, such that the elastic members 13a may directly extend from the first accommodation member 131 at the outer side of the accommodation unit 13 toward the inner wall of the guide sleeve 12, and come into contact with the inner wall of the guide sleeve 12, thereby reducing processing difficulty, simplifying structure of the accommodation unit 13, and thus improving production and manufacturing efficiency.

Here, the accommodation unit 13 is divided into the first accommodation member 131 and the second accommodation member 132 to perform the split type design, such that difficulty of producing and manufacturing the accommodation unit 13 may be reduced, and production efficiency may be improved.

In some embodiments, with reference to FIG. 6 and FIG. 8 to FIG. 10, the second accommodation member 132 includes an accommodation body 1321 and the elastic members 13a. The elastic members 13a are connected to the accommodation body 1321. The first accommodation member 131 is formed with first openings 131a corresponding to the elastic members 13a respectively. Each of the elastic members 13a passes through a respective one of the first openings 131a to be in contact with the inner wall of the guide sleeve 12.

The elastic members 13a are connected to the accommodation body 1321, that is, the elastic members 13a are arranged on the second accommodation member 132 located at an inner side of the accommodation unit 13.

The first accommodation member 131 is formed with first openings 131a corresponding to the elastic members 13a respectively, that is, the first openings 131a are located on a side wall of the first accommodation member 131.

Here, one of the first openings 131a may correspond to one of the elastic members 13a, or one of the first openings 131a may correspond to multiple ones of the elastic members 13a, or multiple ones of the first openings 131a may correspond to one of the elastic members 13a, or multiple ones of the first openings 131a may correspond to multiple ones of the elastic members 13a, which is not limited here.

Therefore, each of the elastic members 13a passes through a respective one of the first openings 131a to be in contact with the inner wall of the guide sleeve 12, thereby achieving that each of the elastic members 13a extends out of an outer wall of the first accommodation member 131 from a side wall of the accommodation body 1321 by passing through a respective one of the first openings 131a, and achieving that each of the elastic members 13a is in contact with the inner wall of the guide sleeve 12, while structure of the accommodation unit 13 is more reasonable, and processing difficulty is reduced.

In some embodiments, with reference to FIG. 8 to FIG. 10, each of the elastic members 13a include a first connection section 13b and a second connection section 13c sequentially arranged along an axial direction of the accommodation unit 13. The first connection section 13b is connected to the accommodation body 1321. A distance between the first connection section 13b and a central axis of the accommodation unit 13 is increased in a direction from bottom to top of the container 10. A distance between the second connection section 13c and the central axis of the accommodation unit 13 is equal, and the second connection section 13c is in contact with the inner wall of the guide sleeve 12.

It should be noted that the first connection section 13b and the second connection section 13c sequentially arranged along the axial direction of the accommodation unit 13 means that the first connection section 13b and the second connection section 13c may be sequentially arranged along the direction from bottom to top of the container 10, or may be sequentially arranged along a direction from top to bottom of the container 10.

As shown in FIG. 10, the distance between the first connection section 13b and the central axis of the accommodation unit 13 is a, and the distance between the second connection section and the central axis of the accommodation unit 13 is b.

Along the direction from bottom to top of the container 10, a may be changed in a manner of gradually increasing uniformly, increasing in stages, decreasing first and then increasing, or the like, which is not limited here.

It should be noted that the distance between the second connection section 13c and the central axis of the accommodation unit 13 is equal, which may be in a situation where the second connection section 13c is in contact with the inner wall of the guide sleeve 12.

Here, the distance between the second connection section 13c and the central axis of the accommodation unit 13 is equal, which may be completely equal or substantially equal.

It should be noted that the second connection section 13c is configured to be in contact with the inner wall of the guide sleeve 12, and the first connection section 13b is configured to be connected to the second connection section 13c and the accommodation body 1321 respectively, to play a transition role.

Specifically, when the second connection section 13c is in contact with the inner wall of the guide sleeve 12, the first connection section 13b may generate elastic deformation, such that the elastic member 13a generates displacement toward center of the accommodation body 1321, thereby generating friction resistance between the guide sleeve 12 and the accommodation unit 13.

Exemplarily, each of the elastic member 13a has a sheet shape. A sheet-shaped large surface of the second connection section 13c is in contact with the inner wall of the guide sleeve 12, thereby increasing area of the elastic member 13a contacting the inner wall of the guide sleeve 12, while it is more beneficial to molding and processing the second accommodation member 132.

Here, with the first connection section 13b and the second connection section 13c sequentially arranged along the axial direction of the accommodation unit 13, it may achieve connection between the elastic member 13a and the second accommodation member 132, while elastic deformation is generated by the first connection section 13b, thereby achieving abutment between the guide sleeve 12 and the elastic member 13a.

In some embodiments, with reference to FIG. 8 to FIG. 10, each of the elastic members 13a further includes a third connection section 13d. The third connection section 13d is connected to an end of the second connection section 13c away from the first connection section 13b. The accommodation body 1321 is formed with second openings 132a corresponding to the first openings 131a respectively. Each of the elastic members 13a is arranged at a respective one of the second openings 132a and extends along an axial direction of the accommodation body 1321. A distance between the third connection section 13d and the central axis of the accommodation unit 13 is decreased in the direction from bottom to top of the container 10.

As shown in FIG. 10, the distance between the third connection section 13d and the central axis of the accommodation unit 13 is c.

Along the direction from bottom to top of the container 10, c may be changed in a manner of gradually decreasing uniformly, decreasing in stages, increasing first and then decreasing, or the like, which is not limited here.

It may be understood that c is decreased along the direction from bottom to top of the container 10, which may make the third connection section 13d extend from the inner wall of the guide sleeve 12 toward interior of the accommodation unit 13, thereby improving a situation where the elastic member 13a easily scratches the inner wall of the guide sleeve 12, it is beneficial for assembly of the accommodation unit 13.

It should be noted that in the direction from bottom to top of the container 10, the first connection section 13b, the second connection section 13c and the third connection section 13d may be sequentially arranged along the axial direction.

The accommodation body 1321 is formed with second openings 132a corresponding to the first openings 131a respectively, that is, the first openings 131a are provided corresponding to the second openings 132a, and one of the first openings 131a may correspond to one of the second openings 132a, or one of the first openings 131a may correspond to multiple ones of the second openings 132a, or multiple ones of the first openings 131a may correspond to one of the second openings 132a, or multiple ones of the first openings 131a may correspond to multiple ones of the second openings 132a, which is not limited here.

Furthermore, the second opening 132a and the first opening 131a may have the same or different sizes.

It may be understood that the second opening 132a is configured to avoid the third connection section 13d, to prevent interference between the third connection section 13d and the accommodation body 1321.

A number of the second openings 132a may be the same as or different from a number of the first openings 131a. Exemplarily, the number of the second openings 132a is one, two, three, four, five, six, seven, eight, or the like, which is not limited here. Meanwhile, the second openings 132a may be arranged at intervals around the outer circumference of the side wall of the accommodation unit 13.

Each of the elastic members 13a is arranged at a respective one of the second openings 132a, that is, the elastic member 13a may be connected to any side of the second opening 132a. Therefore, the elastic member 13a passes through the first opening 131a from the second opening 132a, and extends out of the outer wall 13f of the accommodation unit, to be in contact with the inner wall of the guide sleeve 12.

In this way, the third connection section 13d is provided for the elastic member 13a, and the distance between the third connection section 13d and the central axis of the accommodation unit 13 is decreased, such that the third connection section 13d extends from the inner wall of the guide sleeve 12 toward interior of the accommodation unit 13, thereby improving a situation where the elastic member 13a easily scratches the inner wall of the guide sleeve 12, while it is also beneficial for assembly of the accommodation unit 13.

In some embodiments, with reference to FIG. 8 to FIG. 10, the accommodation body 1321 is provided with an accommodation chamber 1321a configured to accommodate the cosmetic product. The third connection section 13d extends into the accommodation chamber 1321a and abuts against the cosmetic product.

It should be noted that the third connection section 13d extends into the accommodation chamber 1321a and abuts against the cosmetic product located in the accommodation chamber 1321a, thereby enhancing fixation of the cosmetic product.

It may be understood that in a process of the user using the cosmetic product, the cosmetic product is usually subjected to a force along the direction from top to bottom of the container 10, such that the cosmetic product is easily squeezed and deformed outward along the radial direction, and a contact area of the cosmetic product along the third connection section 13d is increased, thereby further improving a locking force of the cosmetic product, and improving a situation where the cosmetic product easily drops out along the axial direction.

Here, the third connection section 13d of the elastic member 13a extends into the accommodation chamber 1321a and abuts against the cosmetic product located in the accommodation chamber 1321a, thereby enhancing fixation of the cosmetic product by the accommodation unit 13, and improving a situation where the cosmetic product easily drops out along the axial direction.

In some embodiments, with reference to FIG. 8 to FIG. 10, the first accommodation member 131 and the second accommodation member 132 are in an interference fit, an adhesive fit or a clamping fit there-between.

It should be noted that since the second accommodation member 132 is arranged in the first accommodation member 131, the interference fit between the first accommodation member 131 and the second accommodation member 132 may be an interference fit between an inner wall of the first accommodation member 131 and an outer wall of the second accommodation member 132.

The adhesive fit means that the first accommodation member 131 and the second accommodation member 132 are connected by adhesives there-between, and at this time, there may be an interference fit or a clearance fit between the inner wall of the first accommodation member 131 and the outer wall of the second accommodation member 132.

The clamping fit may be clamping by buckles or other forms.

Exemplarily, when the second accommodation member 132 is placed in the first accommodation member 131, a certain pressure is applied to an overlapping area between the first accommodation member 131 and the second accommodation member 132 along the radial direction, and an action area of the pressure in the overlapping area is small, such that the first accommodation member 131 and the second accommodation member 132 in a part of the overlapping area are simultaneously deformed to form an inward recess or an outward protrusion, and one or more recesses or protrusions are formed in a circumferential direction of the accommodation unit 13, thereby achieving fixation between the first accommodation member 131 and the second accommodation member 132.

Therefore, the first accommodation member 131 and the second accommodation member 132 are relatively fixed more firmly by cooperation between the first accommodation member 131 and the second accommodation member 132, improving structural stability and structural strength of the accommodation unit 13.

In some embodiments, with reference to FIG. 6 and FIG. 8 to FIG. 10, an inner wall of the accommodation unit 13 is provided with retention ribs 13g extending along an axial direction of the accommodation unit 13.

It should be noted that a number of the retention ribs 13g arranged on the inner wall of the accommodation unit 13 is at least one.

Exemplarily, the number of the retention ribs 13g is one, two, three, four, five, six, seven, eight, or the like, which is not limited here.

Exemplarily, at least two retention ribs 13g are uniformly distributed in a circumferential direction of the inner wall of the accommodation unit 13.

Exemplarily, the retention ribs 13g extend in the axial direction of the accommodation unit 13, and a top end of each of the retention ribs 13g is higher than a respective one of the protruded components 13e. The retention ribs 13g are integrally formed with the accommodation unit 13, and the retention ribs 13g are obtained by deformation of the side wall of the accommodation unit 13. Along the axial direction of the accommodation unit 13, the retention ribs 13g transition smoothly, and a protruded distance of a side of each of the retention ribs 13g away from bottom of the accommodation unit 13 is less than a protruded distance of a side of each of the retention ribs 13g close to the bottom of the accommodation unit 13, such that it is easier to keep the shape of the cosmetic product, while it facilitates assembly of the cosmetic product and the accommodation unit 13, and the cosmetic product may also be guided in a certain direction when it is inserted into the accommodation unit 13.

Therefore, the retention ribs 13g extending along the axial direction of the accommodation unit 13 are arranged on the inner wall of the accommodation unit 13, such that connection between the cosmetic product located in the accommodation unit 13 and the accommodation unit 13 is more reliable, it is easier to keep the shape of the cosmetic product, while it is beneficial for assembly of the cosmetic product and the accommodation unit 13.

In some embodiments, with reference to FIG. 7, each of the guide grooves 12a includes locking components 12b extending along a circumferential direction of the container 10 and a guide component 12c extending along an axial direction of the container 10. The locking components 12b are arranged at both ends of the guide component 12c along the axial direction of the container 10 respectively. The guide component 12c limits positions of the protruded components 13e in the circumferential direction of the container 10, to drive the accommodation unit 13 to move along the axial direction of the container 10. The locking components 12b limit positions of the protruded components 13e in the axial direction of the container 10.

It should be noted that since the protruded components 13e are subjected to an action of force of inclined surfaces of the spiral grooves in the transmission component 11a and have a tendency of spiral motion, the guide component 12c extending along the axial direction of the container 10 limits positions of the protruded components 13e in the circumferential direction, such that the tendency of spiral motion of the protruded components 13e is converted to motion along the axial direction.

Exemplarily, when the protruded component 13e moves from bottom to top of the container 10 along the axial direction, the tendency of spiral motion of the protruded component 13e is spiral rise in a clockwise direction as viewed from top to bottom of the container 10, the protruded component 13e is in contact with one side wall of the guide component 12c, and thus the tendency of spiral motion is converted to motion along the axial direction. When the protruded component 13e moves to a top locking component 12b along the axial direction, the protruded component 13e loses limitation of its position by the guide component 12c in the circumferential direction, and enters the locking component 12b along a clockwise spiral rise direction. The locking component 12b not only limits position of the protruded component 13e in the axial direction of the container 10, but also limits position of the protruded component 13e in the circumferential direction of the container 10, to prevent the protruded component 13e from continuing to spirally rise in a clockwise direction, thereby improving a situation where the protruded component 13e easily drops out of the guide sleeve 12.

When the protruded component 13e moves from top to bottom of the container 10 along the axial direction, the tendency of spiral motion is spiral fall in a counterclockwise direction as viewed from top to bottom of the container 10, the protruded component 13e located at the top locking component 12b of the container 10 drops out and comes into contact with another side wall of the guide component 12c, and the tendency of counterclockwise spiral fall is converted to motion toward the bottom of the container 10 along the axial direction.

It may be understood that a bottom locking component 12b of the container 10 also plays a role similar to the top locking component 12b, thereby improving a situation where the accommodation unit 13 drops out of the guide groove 12a and becomes stuck in bottom of the guide sleeve 12.

In this way, the locking components 12b extending along the circumferential direction of the container 10 and the guide component 12c extending along the axial direction of the container 10 are provided, thereby improving a situation where the protruded component 13e easily drops out of the guide sleeve 12.

The above descriptions are only preferred embodiments of the application, and are not intended to limit the application, and various modifications and variations may be made to the application by those skilled in the art. Any modification, equivalent replacement, improvement, or the like made within the spirit and principle of the application should be included in the scope of protection of the application.
