CROSS-REFERNECE TO RELATED APPLICATION

This application is a continuation of U.S. Application No. 17/621,393, filed on Dec. 21, 2021, which is a national stage entry under 35 USC 371 of PCT/KR2021/013187, filed on Sep. 28, 2021, and claims priority to Korean patent application No. 10-2020-0140747, filed on Oct. 27, 2020, the entire disclosures of which are incorporated herein by reference.

TECHNICAL FIELD

The present invention relates to a cosmetic container, and more particularly, to a contents container in which a discharge portion and/or container body is formed of the same material.

BACKGROUND ART

Up until now, a cosmetics container has been configured so that cosmetics are accommodated in a container body and the container body is opened or closed using a lid so as to take the cosmetics out of the container body when the container body is opened and to apply the cosmetics to the skin. However, in this case, since it is difficult to adjust an amount of cosmetics discharged from the container body, there is a problem of wasting the cosmetics.

In order to remedy the above problem, in order to use highly functional cosmetics such as essence and the like of which a fixed amount needs to be used, pipette type containers capable of extracting a fixed amount of cosmetics from an inside of a contents container have been developed.

A pipette type container generally includes a container body in which contents are accommodated, a cap portion configured to seal the container body, a pipette portion coupled to the cap portion, inserted into the container body, and configured to suction and discharge the contents accommodated in the container body, a pressurizing portion coupled to an upper side of the pipette portion and configured to cause a change in pressure inside the pipette portion, and the like.

However, the pipette type container includes one or more components embodied using a plurality of different materials, and thus there is an inconvenience of separating components when the container is discarded. Also, since it is necessary to separately mold and assemble the pipette portion, pressurizing portion, cap portion, and the like, a configuration of a product becomes complicated and manufacturing costs increase.

Accordingly, a cosmetics container capable of remedying such problems is required.

DISCLOSURE

Referring to FIGS. 1A to 4, a contents container 1000 may include a container body 100 and a discharge portion 200, 300, and 400.

The container body 100 may accommodate contents therein and include a neck portion 110 having an open upper surface and protruding upward from an upper end thereof so that a pipette portion 200 configured to discharge the contents may be inserted into and withdrawn from the container body 100. Here, the contents accommodated in the container body 100 may be, for example, liquid or gel type cosmetics such as serum, essence, cream, and the like. However, the present invention is not limited thereto, and a variety of other formulations or a variety of types of contents such as medications or sanitary aids which are dischargeable through the pipette portion 200 may be applied.

In one embodiment, the container body 100 may be formed of a polypropylene material. However, the present invention is not limited thereto, and a variety of materials may be applied.

In one embodiment, at least a part of the container body 100 may be formed of a transparent or semitransparent material. Accordingly, a user may see a remaining amount of the contents stored in the container body 100 with the naked eye.

A cap portion 300 may be detachably coupled to the neck portion 110. To this end, a first screw thread 111 may be formed on an outer circumferential surface of the neck portion 110 and a second screw thread 321 corresponding thereto may be formed inside the cap portion 300. For example, according to unidirectional rotation, since the cap portion 300 is screw-coupled to the neck portion 110, the cap portion 300 may be detachably coupled to the container body 100. However, this coupling method is merely an example, and the present invention is not limited thereto. In addition thereto, the neck portion 110 and the cap portion 300 may be coupled to each other through a variety of coupling methods such as a snap-on method and the like.

As one embodiment, a wiper (not shown), which is configured to push contents coated on an outer surface of the pipette portion 200 into the container body 100 when the pipette portion 200 is withdrawn, may be further provided inside the container body 100. For example, the wiper may be formed to extend downward from one region of an inner surface of the neck portion 110 and may include a through hole in a center thereof. While the discharge portion 200, 300, and 400 is coupled and separated, the pipette portion 200 may be inserted into or withdrawn from the container body 100 through the through hole. The wiper may be formed of the same type of material as those of the container body 100 and/or the discharge portion 200, 300, and 400, for example, a polypropylene-based material. However, the present invention is not limited thereto, and a variety of materials may be applied according to an embodiment of the present invention.

The discharge portion 200, 300, and 400 may include the pipette portion 200, the cap portion, and a pressurizing portion 400.

The pipette portion 200 may be inserted into and withdrawn from the container body 100 and may suction and discharge the contents of the container body 100. For example, the pipette portion 200 may include a hollow therein and suction the contents in according to a change in pressure thereinside, and the user may withdraw the pipette portion 200 in which the contents has been suctioned from the container body 100 and discharge the contents to the skin.

The pipette portion 200 may be detachably coupled to the cap portion 300 through a coupling portion 210 formed on an upper end thereof. Accordingly, the user may easily assemble the pipette portion 200 with the cap portion 300, may separate or remove one of the pipette portion 200 and the cap portion 300, or may replace the pipette portion 200 or the cap portion 300 with another.

The coupling portion 210 may include a mounting portion 211 and a bending portion 212.

The mounting portion 211 may be formed to protrude outward along an edge of the upper end of the pipette portion 200. Here, the mounting portion 211 may be formed to have an outer diameter greater than an inner diameter of the neck portion 110 so as to be mounted on an upper end of the neck portion 110 when the container body 100 and the discharge portion 200, 300, and 400 are coupled. For example, when the discharge portion 200, 300, and 400 is coupled to the container body 100, the mounting portion 211 may pressurize the upper end of the neck portion 110 downward while being mounted on the upper end of the neck portion 110 and may be completely pressed against an upper end surface of the neck portion 110. Accordingly, even without additional particular components, the neck portion 110 may be firmly sealed. In some embodiments, at least a part of a lower surface of the mounting portion 211 may be formed of soft or elastic material in order to increase a sealing force.

The bending portion 212 may be formed to extend upward, to a certain height, from an outer perimeter of the mounting portion 211 and may be inserted into and coupled to a space between a first edge 310 and a second edge 320 of an inside of the cap portion 300. Here, the bending portion 212 is formed to have a height corresponding to the first edge 310 and may include at least one region having a thickness greater than the space between the first edge 310 and the second edge 320. Accordingly, the bending portion 212 is completely pressed against the space between the first edge 310 and the second edge 320 so as to allow the pipette portion 200 and the cap portion 300 to be firmly coupled.

In some embodiments, a coupling protrusion and/or a coupling groove which are configured to increase a coupling force may be further formed on an inner circumferential surface and/or an outer circumferential surface of the bending portion 212, an outer circumferential surface of the first edge 310, and/or an inner circumferential surface of the second edge 320.

In one embodiment, at least a part of the pipette portion 200 may be formed of a transparent material. Accordingly, the user may see an amount, color, and the like of the contents suctioned in the pipette portion 200.

The cap portion 300 may be detachably coupled to the neck portion 110 so as to seal the container body 100. Also, when the coupling portion 210 of the pipette portion 200 is coupled to an inside of the cap portion 300 and the cap portion 300 is coupled to the container body 100, the pipette portion 200 may be accommodated in the container body 100.

Inside the cap portion 300, the first edge 310 extending downward from an upper surface and the second edge 320 extending downward from the upper surface and disposed to be spaced apart from an outside of the first edge 310 may be formed. The cap portion 300 and the pipette portion 200 may be detachably coupled by inserting and coupling the bending portion 212 into and to the space between the first edge 310 and the second edge 320.

A second screw thread 321 having a shape corresponding to the first screw thread 111 of the neck portion 110 may be formed on an inner surface of the second edge 320. Accordingly, the cap portion 300 may be screw-coupled to the neck portion 110. Accordingly, through unidirectional rotation of the cap portion 300, the container body 100 and the discharge portion 200, 300, and 400 may be coupled and/or separated. However, the present invention is not limited thereto, and a variety of coupling methods such as coupling using a coupling protrusion and a coupling groove formed instead of the first screw thread 111 and the second screw thread 321 and the like may be applied in some embodiments of the present invention.

The cap portion 300 may include a third edge 330 disposed to be spaced outward apart from the second edge 320 and extending downward from a perimeter of the upper surface. The third edge 330 may form an outer surface of the cap portion 300, may be a part grippable when the user separates or couples the discharge portion 200, 300, and 400 from or to the container body 100, and may prevent the second edge 320 coupled to the neck portion 110 from being directly exposed to the outside so as to prevent the second edge 320 from being damaged.

When the neck portion 110 and the cap portion 300 are coupled, the third edge 330 may be mounted on the upper end of the container body 100. For example, the container body 100 may include a restricting step (with no reference numeral) protruding upward along an edge of a lower end of the neck portion 110 and configured to allow the third edge 330 to be mounted on top of the restricting step when the neck portion 110 is completely sealed through the unidirectional rotation of the cap portion 300.

As one embodiment, one or more restricting protrusions 331 may be formed along a perimeter of an inner circumferential surface of a lower end of the third edge 330. For example, the restricting protrusion 331 may be formed to protrude inward from the third edge 330 and to have one side having a repeated saw-toothed shape tilted at a certain angle. When the user excessively rotates the cap portion 300 during a process of coupling the cap portion 300, the restricting protrusion 331 may come into contact with the restricting step and may allow the user to recognize a coupling state of the cap portion 300.

In one embodiment, one or more holding protrusions (not shown) may be formed on the restricting step. When the cap portion 300 rotates in one direction and thus the third edge 330 reaches a certain height from the restricting step, the holding protrusion may be held between the restricting steps so as to prevent the cap portion 300 from additional rotation in one direction.

The pressurizing portion 400 may be formed above the cap portion 300 and may generate a change in pressure to allow the contents to be suctioned in and discharged from the pipette portion 200. To this end, an inside of the pressurizing portion 400 may communicate with the inside of the pipette portion 200. For example, the pressurizing portion 400 may be formed to communicate with an internal space of the first edge 310 so that the inside of the pressurizing portion 400 may communicate with the inside of the pipette portion 200 when the bending portion 212 of the pipette portion 200 is inserted into and coupled to the space between the first edge 310 and the second edge 320 of the cap portion 300.

The pressurizing portion 400 may be formed to be elastically deformable according to pressurization of the user. For example, when the cap portion 300 and the pressurizing portion 400 are integrally molded, the pressurizing portion 400 may be molded to have a thickness capable of having elasticity. Accordingly, according to pressurizing and releasing of the user, a volume inside the pressurizing portion 400 may be reduced or increased so as to generate a change in internal pressure of the pipette portion 200.

According to one embodiment, the pressurizing portion 400 may be formed to have a variety of shapes. Since the discharge portion 200, 300, and 400 may generate a change in pressure inside the pipette portion 200 through an internal space of the pressurizing portion 400 and an internal space of the first edge 310, a variety of shapes in which a volume of the internal space of the pressurizing portion 400 is changeable may be applied. For example, the pressurizing portion 400 is formed to have a button shape, or a variety of other shapes such as a quadrangular shape, a triangular shape, and the like are applied to the pressurizing portion 400 so that a variety of types of aesthetics may be provided to the user.

The discharge portion 200, 300, and 400 may be formed of a polypropylene-based material. Particularly, the pressurizing portion 400 may be formed of a polypropylene material in which polyolefin elastomer (POE) is mixed to have elasticity of a certain degree or higher. However, the present invention is not limited thereto, and a variety of materials may be applied. Particularly, the cap portion 300 and the pressurizing portion 400 are formed of the same polypropylene-based materials and integrally formed through double injection molding so that a configuration of a container may be simplified and manufacturing costs may be reduced.

According to an embodiment, the container body 100 and the discharge portion 200, 300, and 400 may be formed of the same types of materials. Here, the container body 100 and the discharge portion 200, 300, and 400 are formed of polypropylene-based materials so that there is an advantage of disposing a container without needing to be separately disposed. However, the present invention is not limited thereto, and a variety of materials may be applied according to an embodiment to which the present invention is applied.

As described above, optimum embodiments have been shown and described in the drawings and the specification. The particular terms used herein are merely intended to describe the present invention and are not used to limit the meanings or restrict the scope of the present invention disclosed in the claims. Therefore, it should be understood by one of ordinary skill in the art that a variety of modifications and equivalents thereof may be made. Accordingly, the technical scope of the present invention should be determined by the technical concept of the following claims.
