CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of Korean Patent Application No. 10-2022-0130189, filed with the Korean Intellectual Property Office on Oct. 12, 2022, the disclosure of which is incorporated herein by reference in its entirety.

BACKGROUND

1. Technical Field

The present invention relates to a cosmetic container that can prevent deformation caused by the content.

2. Description of the Related Art

A cosmetic product stored in a cosmetic container can be of a variety of forms, including liquids, gels, solids, powders, etc., and the components of the cosmetic product can also vary greatly according to the purpose or usage of the cosmetic product. In recent times, it is not uncommon to find a cosmetic product that provides various functions rather than a single function, such as a tone-up cream, for example, that can double as a sunscreen to block ultraviolet rays in addition to providing its original purpose of brightening skin tone. Such multi-functional cosmetic products generally provide strong stimuli on the skin.

As cosmetic products provide stronger stimuli, the problem may arise of the cosmetic container itself being deformed by the cosmetic product. For example, in a current cushion compact case (as used for holding cosmetic foundation), the cosmetic product may seep into the container and cause deformation.

SUMMARY OF THE INVENTION

An aspect of the present invention, which was conceived to resolve the problem described above, is to provide a cosmetic container that can prevent any deformation of the container by the content.

Other objectives of the present invention will be more clearly understood from the embodiments set forth below.

A cosmetic container according to one aspect of the invention includes: a lower case that includes a case bottom and an inner rim and forms an internal space, an upper case that is rotatably coupled to the lower case and is configured to cover the top of the lower case, a protective tray that is configured to be inserted in the internal space and includes a tray rim and a tray bottom, and a securing ring that is configured to couple the protective tray to the lower case; where the lower case includes an outer rim, which is formed with a particular gap from the circumference of the inner rim; the securing ring includes a ring flange, which has an annular shape, and a ring rim, which extends from the ring flange; the ring flange contacts the upper end of the tray rim; and the ring rim is inserted into an insertion groove formed between the inner rim and the outer rim so as to contact the outer perimeter of the inner rim.

A cosmetic container according to an embodiment of the present invention can include one or more of the following features. For example, the protective tray can be fabricated from polyethylene terephthalate (PET).

The tray rim can have the same height as the inner rim.

An outwardly protruding detent protrusion can be formed at an end portion of the tray rim, and the detent protrusion can be positioned at the upper end of the inner rim and can be pressed down by the ring flange.

A coupling groove can be formed in the outer perimeter of the inner rim, and a ring-coupling protrusion configured to be inserted in the coupling groove can be formed on the inner perimeter of the ring rim.

An embodiment of the present invention having the features above can provide various advantageous effects including the following. However, an embodiment of the present invention may not necessarily exhibit all of the effects below.

FIG. 1 is an exploded perspective view of a cosmetic container 100 according to an embodiment of the invention, and FIG. 2 is a cross-sectional view of the cosmetic container 100 illustrated in FIG. 1 in its assembled state.

Referring to FIG. 1 and FIG. 2, a cosmetic container 100 according to this embodiment may include an upper case 110 and a lower case 150 as well as a protective tray 140 located therein for protecting the lower case 150 and a securing ring 130 for coupling the protective tray 140 to the lower case 150. The protective tray 140 may be coupled to the inside of the lower case 150 to prevent the lower case 150 from being deformed or damaged by the cosmetic product and can be made of a material that is different from that of the lower case 150.

The upper case 110 and the lower case 150 may form the exterior of the cosmetic container 100. The cosmetic container 100 can be used independently or as an inner container that is coupled within another container (not shown). The upper case 110 and the lower case 150 can be made from a material such as polypropylene (PP), polyethylene (PE), etc. Also, the upper case 110 and the lower case 150 can be made from a material that is different from that of the protective tray 140.

The upper case 110 may be rotatably coupled to the lower case 150 and may cover the open top of the lower case 150. The upper case 110 may include a case lid 118 and a case rim 116.

The case lid 118 may be a plane that covers the open top of the lower case 150 and can have any of a variety of shapes, such as a circular shape, a polygonal shape, or other, in correspondence to the overall shape of the cosmetic container 100. The case rim 116 may protrude upward from the edge of the case lid 118 to a particular height. The case lid 118 and the case rim 116 may thus form an internal space (no numeral assigned) having an open top in an upper portion of the upper case 110. Such internal space can be used to hold a cosmetic tool (no numeral assigned) such as a puff, etc.

An upper hinge 112 may be formed on the case rim 116. The upper hinge 112 may be rotatably coupled to a lower hinge 152 formed on the lower case 150 to thereby enable the upper case 110 to rotate in relation to the lower case 150. The upper hinge 112 may include a hinge bar 113 having a particular length, where the hinge bar 113 may be rotatably inserted into the lower hinge 152, which may be shaped as a groove.

A handle 114 can be formed at a position of the case rim 116 opposite the upper hinge 112. The handle 114 may protrude outwardly from the case rim 116 and may allow an easy rotating and opening of the upper case 110.

The lower case 150 may form an internal space 164 that is capable of holding a content (not shown), and the lower case 150 may include an inner rim 158, an outer rim 154, and a case bottom 162.

The case bottom 162 may correspond to a lower surface of the cosmetic container 100, and an upper surface of the case bottom 162 can contact the tray bottom 144 of the protective tray 140. The inner rim 158 may be formed protruding upwardly from the edge of the case bottom 162.

The inner rim 158 may be formed with a particular height and may define the height of the internal space 164. The height of the inner rim 158 can be the same as or virtually the same as that of the tray rim 142 of the protective tray 140.

The outer rim 154 may be formed on the outer side of the inner rim 158 with a particular gap in-between. While the outer rim 154 is illustrated as being formed at a particular height from the lower end of the inner rim 158, another embodiment of the invention can have the outer rim 154 extending upward from the lower end of the inner rim 158.

An insertion groove 156 having a particular width may be formed between the inner rim 158 and the outer rim 154. The insertion groove 156 can be formed with a particular width along the entire circumference of the lower case 150. The ring rim 134 of the securing ring 130 may be inserted in the insertion groove 156 such that the inner perimeter of the ring rim 134 tightly contacts the outer perimeter of the inner rim 158. A coupling groove 160 can be formed within the insertion groove 156 in the outer perimeter of the inner rim 158 along the entire circumference or along a portion of the circumference of the inner rim 158, and a ring-coupling protrusion 136 configured to be inserted in the coupling groove 160 can be formed on the inner perimeter of the ring rim 134. Such coupling between the coupling groove 160 and the ring-coupling protrusion 136 may secure the securing ring 130 onto the lower case 150, and as a result, the protective tray 140 can be coupled to the internal space 164 of the lower case 150 in a stable manner.

The lower hinge 152 can be formed on one side of the outer rim 154. The lower hinge 152 may be coupled with the upper hinge 112 to enable the rotation of the upper case 110, as already described above.

The protective tray 140 may have an internal space for holding a content and may be inserted into the internal space 164 of the lower case 150. Thus, the content may contact the protective tray 140 but may not contact the lower case 150. The protective tray 140 may include a tray bottom 144 and a tray rim 142 to be shaped as a container having an open top. The tray bottom 144 may have the same size and shape as, and be placed in contact with, the case bottom 162. Also, the tray rim 142 may have the same size and shape as, and be placed in contact with, the inner rim 158.

The protective tray 140 can be made from a material that is different from that of the lower case 150. For example, in cases where the lower case is made from polyethylene or polypropylene, the protective tray 140 can be made from a polyethylene terephthalate (PET) material. Polyethylene terephthalate (PET) has high chemical resistance and thus can prevent the protective tray 140 from being deformed or damaged by the cosmetic product. The protective tray 140 can also be made from a material having high chemical resistance other than polyethylene terephthalate (PET).

The height of the tray rim 142 can be made the same as that of the inner rim 158. This can allow the outer perimeter of the tray rim 142 to tightly contact the inner perimeter of the inner rim 158. Also, the upper end of the tray rim 142 can be bent outward to form a detent protrusion 141. The detent protrusion 141 can be positioned at the upper end of the inner rim 158 and can be pressed down by the securing ring 130 (see FIG. 2). The detent protrusion 141 can be formed along the entire circumference of the tray rim 142. Such a structure for downward pressing by the detent protrusion 141 and the securing ring 130 can prevent the cosmetic product from leaking in between the tray rim 142 and the inner rim 158.

The securing ring 130 may serve to secure the protective tray 140 onto the lower case 150 and may be coupled to an upper portion of the inner rim 158. The securing ring 130 may include a ring flange 132 having an annular shape (structured with an open center) and a ring rim 134 extending downward from the edge of the ring flange 132.

The ring flange 132 may be shaped as a short inward protrusion formed at the upper end of the ring rim 134. Thus, the ring flange 132 may correspond to a ring-shaped plane having a narrow width. The ring flange 132 may press down while contacting the detent protrusion 141 of the protective tray 140 to thereby allow the protective tray 140 to be coupled in the internal space 164 in a stable manner.

The ring rim 134 may have a particular height and a circular horizontal cross section. The ring rim 134 can be inserted into the insertion groove 156 formed around the lower case 150 so as to be coupled to the lower case 150 in a stable manner. That is, the ring-coupling protrusion 136 formed on the inner perimeter of the ring rim 134 may be inserted into the coupling groove 160 formed in the inner rim 158, so that the securing ring 130 may be coupled to the lower case 150 in a stable manner.

While the foregoing provides a description with reference to an embodiment of the present invention, it should be appreciated that a person having ordinary skill in the relevant field of art would be able to make various modifications and alterations to the present invention without departing from the spirit and scope of the present invention set forth in the scope of claims below.
