Casings or accessories for storing or handling solid or pasty toilet or cosmetic substances, e.g. shaving soap, lipstick, make-up; Casings wherein movement of the lipstick or like solid is a sliding movement effected by a screw
The present invention relates to a container.
Generally, cosmetics are largely classified into solid, powder, and liquid type cosmetics, and a variety of containers are used according to the different types of cosmetics. In the case of the solid cosmetics such as foundations, lipsticks, and the like, a rotary type cosmetic container has been widely used.
According to the conventional rotary type cosmetic container, a cap is first open, and next, a rotary body disposed on the underside of the container rotates to allow a solid type stick cosmetic to be lifted and lowered from and into the container. For example, if it is desired to use a solid type cosmetic such as a lipstick, a cap of a lipstick container is first open, and next, a rotary body of the container rotates in one direction to allow the lipstick cosmetic to be lifted and exposed to the outside. After the use of the lipstick, the rotary body of the container rotates in the opposite direction to one direction, the lipstick cosmetic is lowered and thus received in the container.
While the conventional rotary type cosmetic container is rotating with a rotational force applied from a user, however, it is not easy that a rotational degree (or rotational speed) of the rotary body is intuitively recognized by the user.
Accordingly, it is an object of the present invention to provide a container that is capable of solving such problems.

Referring to FIGS. 1 to 4, a container 1000 according to an embodiment of the present invention largely includes a housing part 100, a lifting/lowering guide part 200, a lifting/lowering part 300, an upper cap 400, and a lower cap 500.
The housing part 100 is configured to allow the lifting/lowering part 300 to be located therein and receives a rotational force from a user. For example, as the lifting/lowering guide part 200 and the housing part 100 that are exposed to the outside are grasped by the user to apply the rotational force to the housing part 100 from the user, the housing part 100 rotates relative to the lifting/lowering guide part 200.
According to the embodiment of the present invention, the housing part 100 consists of a housing body 110 and a housing cap 120.
The housing body 110 has the shape of a tube open on top and bottom thereof and receives the lifting/lowering part 300 and a portion of the lifting/lowering guide part 200 therein. The housing body 110 has at least one or more first fastening protrusions 111 along the inner peripheral surface of a lower end thereof. For example, the first fastening protrusions 111 extend to a given length toward a longitudinal direction (or an up and down direction) of the housing body 110 in such a way as to be spaced apart from one another along the inner peripheral surface of the housing body 110. The housing body 110 is synchronizedly rotatably connected with a driver 320 of the lifting/lowering part 300 by means of the first fastening protrusions 111.
Further, the housing body 110 has a plurality of second fastening protrusions 112 and coupling protrusions 113 on the outer peripheral surface of an upper end thereof, through which the housing body 110 is synchronizedly rotatably connected with the housing cap 120. For example, the second fastening protrusions 112 extend to a given length toward the longitudinal direction (or the up and down direction) of the housing body 110 in such a way as to be spaced apart from one another along at least a given area of the outer peripheral surface of the upper end of the housing body 110. Further, the coupling protrusions 113 are formed along the outer peripheral surface of the housing body 110 in such a way as to be located under the second fastening protrusions 112.
The housing cap 120 is coupled to the housing body 110 in such a way as to surround the upper end of the housing body 110. The housing cap 120 has at least one or more third fastening protrusions 121 and coupling grooves (with no reference numerals) along the inner peripheral surface thereof. For example, the third fastening protrusions 121 extend to a given length toward a longitudinal direction (or an up and down direction) of the housing cap 120 in such a way as to be spaced apart from one another along the inner peripheral surface of the housing cap 120. Further, the coupling grooves are located under the third fastening protrusions 121.
If the top end of the housing body 110 is inserted into the housing cap 120, the second fastening protrusions 112 engage with the third fastening protrusions 121 and the coupling protrusions 113 are fittedly coupled to the coupling grooves, thereby allowing the housing cap 120 and the housing body 110 to be synchronizedly rotatably connected with each other.
The housing cap 120 has at least one or more fitting protrusions 122 on the outer peripheral surface thereof in such a way as to allow the upper cap 400 to be detachably coupled thereto.
Further, the housing body 110 and the housing cap 120 are provided separately from each other and thus coupled to each other, which is just exemplary. According to embodiments of the present invention, therefore, the housing body 110 and the housing cap 120 may be provided as a unitary body.
The lifting/lowering guide part 200 serves to guide the content to be lifted and lowered so that the content is exposed to the outside and thus used by the user. An upper portion (particularly, a lifting/lowering guide tube 210) of the lifting/lowering guide part 200 is exposed to the outside from the top of the housing part 100, and a lower portion (particularly, a lower support tube 220) of the lifting/lowering guide part 200 is inserted into the housing part 100 and connected to a second gear 340 as will be discussed later.
The lifting/lowering guide part 200 includes the lifting/lowering guide tube 210 and the lower support tube 220.
The lifting/lowering guide tube 210 is configured to allow the content and a receiving portion 311 to be received therein and serves to guide the content to be lifted and lowered. The lifting/lowering guide tube 210 has an outlet 211 open on top thereof to allow the content to be exposed to the outside. The housing part 100 rotates to allow the content to be exposed to the outside from the outlet 211, and next, the content is applied to a desired area such as lips, and the like.
The lifting/lowering guide tube 210 has a lower end with larger inner and outer diameters than the other area thereof so as to receive the upper end of the lower support tube 220 therein. The lifting/lowering guide tube 210 has at least one or more incised portions 212 on the outer peripheral surface of the lower end thereof in such a way as to be synchronizedly rotatably connected with the lower support tube 220.
The lower support tube 220 is received in the housing part 100 and synchronizedly rotatably connected with the lower side of the lifting/lowering guide tube 210. To do this, the lower support tube 220 has coupling protrusions 221 on the outer peripheral surface of the upper end thereof in such a way as to correspond to the incised portions 212 of the lifting/lowering guide tube 210. In detail, as the upper end of the lower support tube 220 is inserted into the lower end of the lifting/lowering guide tube 210, the coupling protrusions 221 are received in the corresponding incised portions 212, so that the lower support tube 220 is synchronizedly rotatably connected with the lifting/lowering guide tube 210.
The second gear 340 is synchronizedly rotatably connected with the interior of the lower support tube 220. To do this, the lower support tube 220 has at least one or more fourth fastening protrusions 222 along the inner peripheral surface of an upper end thereof. For example, the fourth fastening protrusions 222 extend to a given length toward a longitudinal direction (or an up and down direction) of the lower support tube 220 in such a way as to be spaced apart from one another along the inner peripheral surface of the lower support tube 220.
The lifting/lowering part 300 is located inside the housing part 100 to support or mount the content thereon, and further, the lifting/lowering part 300 lifts and lowers the content according to the rotations of the housing part 100.
The lifting/lowering part 300 includes a content holder 310, a driver 320, a first gear 330, and the second gear 340.
The content holder 310 supports the content against the bottom thereof to allow the content to be mounted inside the lifting/lowering guide part 200. In this case, the content is a solid or semi-solid cosmetic applied to a user′ skin. For example, the content may be a stick type cosmetic, but without being limited thereto, the content may be a medical material or other types of contents.
The content holder 310 rotates relative to the driver 320 according to the rotations of the housing part 100 and is thus lifted and lowered together with the content.
To do this, the content holder 310 has a first lifting/lowering protrusion 312-1 on the outer peripheral surface thereof, and the driver 320 has a second lifting/lowering protrusion 321 on the inner peripheral surface thereof. For example, the first lifting/lowering protrusion 312-1 extends in the form of a screw thread over a given area of the outer peripheral surface of the content holder 310, and the second lifting/lowering protrusion 321 extends in the form of a screw thread over a given area of the inner peripheral surface of the driver 320. While the housing part 100 is rotating, the first lifting/lowering protrusion 312-1 and the second lifting/lowering protrusion 321 rotate relative to each other in the opposite directions to each other, thereby lifting and lowering the content holder 310.
The content holder 310 includes a receiving portion 311 and rods 312 and 313.
The receiving portion 311 is open on top thereof to allow at least a portion of the content to be received therein. For example, the lower end of the content is supportedly received inside the receiving portion 311, and the remaining area of the content is received in the lifting/lowering guide tube 210.
The rods 312 and 313 extend downward from the underside of the receiving portion 311 in such a way as to allow at least a portion thereof to be inserted into the driver 320. The first lifting/lowering protrusion 312-1 is formed on the outer peripheral surface of the rods 312 and 313.
The rods 312 and 313 each have a non-circular horizontal sectional shape. As will be discussed later, the rods 312 and 313 with the non-circular sectional shape are inserted into a through hole 342 of the second gear 340 having the corresponding shape thereto, so that the content holder 310 is synchronizedly rotatably connected with the second gear 340.
According to the embodiment of the present invention, the rod 312 represents the body 312 and the rod 313 represents the insertion member.
The body 312 extends from the underside of the receiving portion 311 in such a way as to be formed unitarily with the receiving portion 311. The body 312 has an insertion space formed therein, and the bottom of the body 312 and portions of both side peripheral surfaces of the body 312 in one direction are open to communicate with the insertion space. The first lifting/lowering protrusion 312-1 is formed on the outer peripheral surface of the body 312.
The insertion member 313 has the shape of a bar corresponding to the insertion space of the body 312 and is insertedly coupled to the body 312. The side peripheral surface of the insertion member 313 is exposed to the outside through both open sides of the body 312. The insertion member 313 has limitation protrusions 313-1 on the exposed side surfaces to the outside. The limitation protrusions 313-1 are received in receiving grooves 344 of the second gear 340 to limit the lifting height of the content holder 310 or prevent the content holder 310 from being arbitrarily separated from the insertion member 313.
To couple the content holder 310 to the second gear 340, in this case, the body 312 is inserted into the through hole 342 of the second gear 340 above the second gear 340, and next, the insertion member 313 is insertedly coupled to the body 312.
The driver 320 is open on top thereof in such a way as to receive the rods 312 and 313 of the content holder 310 and rotates relative to the content holder 310 to lift and lower the content holder 310. To do this, the driver 320 has the second lifting/lowering protrusion 321 on the inner peripheral surface of the upper end thereof.
The driver 320 has a plurality of fifth fastening protrusions 322 on the outer peripheral surface of the lower end thereof. The fifth fastening protrusions 322 engage with the first fastening protrusions 111 of the housing part 100 so that the driver 320 is synchronizedly rotatably connected with the housing part 100.
The driver 320 has coupling protrusions (with no reference numeral) on the outer peripheral surface of the bottom end thereof in such a way as to allow the lifting/lowering guide part 200 to be rotatable relative thereto. For example, the coupling protrusions each have the shape of a circle along the outer peripheral surface of the driver 320.
The driver 320 has at least one or more vertical guide grooves 323 on the outer peripheral surface of the upper end thereof. For example, the vertical guide grooves 323 extend vertically from the top periphery of the driver 320. The vertical guide grooves 323 guide the upward and downward movements of an upper support body 331-1 of the first gear 330.
The first gear 330 is surroundingly located on the outer peripheral surface of the driver 320. For example, the first gear 330 is located on top of the stepped projection of the lower end of the driver 320.
The first gear 330 includes an elastic member 331 and at least one or more first locking protrusions 332 protruding from top of the elastic member 331.
The elastic member 331 elastically deforms and returns to its original state by means of the downward pressurization of the second gear 340 to allow the first locking protrusions 332 to sequentially engage with second locking protrusions 343 of the second gear 340 that differ from the first locking protrusions 332. As a result, the container 1000 provides clicks (rotational loads and specific sounds) generated according to the rotations of the housing part 100 for the user.
According to the embodiment of the present invention, the elastic member 331 consists of the upper support body 331-1, a lower support body 331-2, deformation members 331-3, and horizontal support bodies 331-4.
The upper support body 331-1 and the lower support body 331-2 serve to support top and bottom of the elastic member 331. The upper support body 331-1 moves down by means of the pressurization and thus transmits the pressurizing force to the deformation members 331-3, and the lower support body 331-2 supports the elastic member 331, without moving up under the elastic deformation of the elastic member 331, to allow the elastic force of the elastic member 331 to be applied to the upper support body 331-1.
The upper support body 331-1 and the lower support body 331-2 have hollow portions therein to allow the driver 320 to be located therein. For example, the upper support body 331-1 and the lower support body 331-2 each have the shape of a ring.
According to the embodiment of the present invention, the upper support body 331-1 has at least one or more vertical guide protrusions 331-11 on the inner peripheral surface thereof. The vertical guide protrusions 331-11 are inserted into the corresponding vertical guide grooves 323 of the driver 320 and move along the vertical guide grooves 323 according to the elastic deformation or restoration of the elastic member 331, thereby guiding the upward and downward movements of the upper support body 331-1.
The deformation members 331-3 connect the upper support body 331-1 and the lower support body 331-2 to each other. If the pressurization for the elastic member (particularly, the upper support body 331-1) occurs, the deformation members 331-3 curvedly deform (that is, elastically compress) to generate elastic forces, and if the pressurization for the elastic member 331 is released, the curved deformation of the deformation members 331-3 is released so that the deformation members 331-3 return to their original state.
According to the embodiment of the present invention, the plurality of deformation members 331-3 are provided. Each deformation member 331-3 consists of a first deformation portion 331-31 extending inclinedly downward from the upper support body 331-1, a second deformation portion 331-32 extending inclinedly upward from the lower support body 331-2 in such a way as to correspond to the first deformation portion 331-31, and a connection portion 331-33 for connecting the first deformation portion 331-31 and the second deformation portion 331-32 to each other in such a way as to allow them to be symmetrical up and down with each other.
In this case, the first deformation portion 331-31 and the second deformation portion 331-32 each have at least one inflection point at which inclination directions are varied.
According to the embodiment of the present invention, the connection portion 331-33 has a thickness greater than the first deformation portion 331-31 and the second deformation portion 331-32. For example, the connection portion 331-33 becomes increase in thickness toward the central portion thereof from both ends where the first deformation portion 331-31 and the second deformation portion 331-32 are located.
The horizontal support bodies 331-4 are located between Deformation member 331-3 and Lower support body 331-2 to connect the two adjacent deformation members 331-3 to each other. According to the embodiment of the present invention, the horizontal support bodies 331-4 connect the central areas of the connection portions 331-33 of the two adjacent deformation members 331-3 to each other. In this case, the two adjacent deformation members 331-3 around the horizontal support bodies 331-4 are symmetrical to each other.
According to the embodiment of the present invention, the horizontal support bodies 331-4 are fixed in shape if the downward pressurization for the first gear 330 and/or the elastic member 331 is performed. The fixed shapes of the horizontal support bodies 331-4 prevent the elastic member 331 from twisting in a process where the deformation members 331-3 elastically deform and return.
The first locking protrusions 332 protrude upward from the periphery of the upper support body 331-1. The first locking protrusions 332 sequentially engage with the second locking protrusions 343 of the second gear 340 that differ therefrom according to the rotations of the housing part 100, thereby providing the rotational loads and specific sound for the user.
Tops of the first locking protrusions 332 are curvedly formed in such a way as to easily move over the end portions of the second locking protrusions 343 and have inclined surfaces on both sides thereof. In this case, both side inclined surfaces of each first locking protrusion 332 have different inclination angles from each other. As a result, different rotational loads according to the rotational directions of the housing part 100 are provided for the user.
The first gear 330 is made of a synthetic resin (particularly, a soft plastic). As the first gear 330 is made of a plastic, it can be easily made at a lower production cost than a conventional metal spring. Further, the first gear 330 is separately thrown away from other components, thereby having eco-friendly advantages.
According to the embodiment of the present invention, the respective components of the first gear 330 may be made of the same material as one another or different materials from one another. According to the embodiment of the present invention, further, the respective components of the first gear 330 may be provided as a unitary body by means of injection molding or separately made and thus coupled to one another.
The second gear 340 is located on top of the first gear 300 in such a way as to be synchronizedly rotatably connected with the inside of the lifting/lowering guide part 200. To allow the second gear 340 to be coupled to the lifting/lowering guide part 200, the second gear 340 has at least one or more sixth fastening protrusions 341 along the outer peripheral surface of the lower end thereof in such a way as to be fastened to the fourth fastening protrusions 222 of the lifting/lowering guide part 200.
The second gear 340 has the through hole 342 on the central portion thereof. The rods 312 and 313 of the content holder 310 pass through the through hole 342 and are thus received in the driver 320. In this case, the through hole 342 has the non-circular sectional shape corresponding to the sectional shapes of the rods 312 and 313.
The second gear 340 has the second locking protrusions 343 protruding downward from the underside periphery thereof. The second locking protrusions 343 have the shapes corresponding to the first locking protrusions 332 of the first gear 330, and if no rotational force is applied to the housing part 100, a state where the first locking protrusions 332 fully engage with the second locking protrusions 343 is kept.
Each second locking protrusion 343 is curved on the underside thereof and has inclined surfaces on both sides thereof. In this case, both side inclined surfaces of each second locking protrusion 343 have different inclination angles from each other in such a way as to correspond to each first locking protrusion 332.
The second gear 340 has the receiving grooves 344 at the inside thereof in such a way as to correspond to the limitation protrusions 313-1 of the content holder 310. For example, the receiving grooves 344 are concave upward from both sides of the through hole 342.
The upper cap 400 is detachably coupled to the upper end (particularly, the housing cap 120) of the housing part 100 in such a way as to block the outlet 211 formed on the end portion of the lifting/lowering guide part 200.
The lower cap 500 is coupled to the bottom end of the housing part 100 in such a way as to block the open bottom end of the housing part 100. For example, the lower cap 500 is inserted into the bottom end of the housing part 100 and thus fittedly coupled thereto.
The container 1000 as shown in FIGS. 1 to 4 is just exemplary, and therefore, the container 1000 may be freely configured according to embodiments of the present invention.
FIGS. 5a and 5b are perspective views showing operations of the container according to an embodiment of the present invention.
Referring first to FIG. 5a, as the first gear 330 of the lifting/lowering part 300 is supported against the elastic member 331 before the rotational force is applied from the user to the container 1000, the first locking protrusions 332 fully engage with the second locking protrusions 343 of the second gear 340.
If the lifting/lowering guide tube 210 and the housing part 100 are grasped by the user to apply the rotational force to the housing part 100, the housing part 100 rotates in one direction, so that as shown in FIG. 5b, the driver 320 and the first gear 330 synchronizedly rotate with the housing part 100 in the same direction. In this case, the second gear 340 and the content holder 310 are connected to the lifting/lowering guide part 200, so that they are kept in fixed states, without any rotations.
As the first gear 330 rotates, the inclined surfaces of the second locking protrusions 343 pressurize the first locking protrusions 332 downward, so that as the elastic member 331 elastically deforms (that is, elastically compresses), the first locking protrusions 332 engage with the second locking protrusions 343 adjacent thereto. In such a way, the first locking protrusions 332 engage with the second locking protrusions 343 that differ therefrom sequentially, thereby providing clicks (rotational loads and specific sounds) generated according to the rotations of the housing part 100 for the user.
While the elastic member 331 compresses and returns to its original state, in this case, the upper support body 331-1 of the elastic member 331 is supported against the vertical guide protrusions 331-11, and further, the deformation portions 331-3 are prevented from twisting by means of the horizontal support bodies 331-4.
If the rotation of the driver 320 relative to the content holder 310 is kept, the content holder 310 and the content are lifted, so that the content is exposed to the outside from the outlet of the lifting/lowering guide tube 210.
If the housing part 100 rotates in the opposite direction to one direction, further, the content holder 310 and the content are lowered, and in the similar operation way, the first locking protrusions 332 engage with the second locking protrusions 343 that differ therefrom sequentially in the opposite direction, thereby providing the rotational loads and specific sounds for the user. In this case, both side inclined surfaces of each first locking protrusion 332 are different from those of each second locking protrusion 343, so that while the housing part 100 rotates in the opposite direction, the rotational loads are generated differently from those in one direction.
The operations of the container 1000 as shown in FIG. 5 are just exemplary, and therefore, operations of the container 1000 may be freely performed according to embodiments of the present invention.
As mentioned above, the preferred embodiment of the present invention has been disclosed in the specification and drawings. Therefore, persons skilled in the relevant art can appreciate that many modifications and variations are possible in light of the above teachings. It is therefore intended that the scope of the invention be limited not by this detailed description, but rather by the claims appended hereto.
