Abstract

The present invention relates to a compact cosmetic container that is easy to recycle, which can improve recycling efficiency by allowing a consumer to easily remove the top surface during the recycling process. By configuring the top surface so that it can be easily separated from the side wall joint, the consumer can easily remove the top surface during the recycling process, and as a result, separation by material is facilitated, thereby improving recycling efficiency.

A container insertion groove of an empty space is formed between the inner surface of the above-mentioned external catch and the outer surface of the above-mentioned refill container, and A compact cosmetic container that is easy to recycle, characterized by further including a container fixing part that is detachably inserted into the container insertion groove and selectively limits the elastic deformation of the external locking part by an external force.

Description

Compact Cosmetic Container with Enhanced Recyclability The present invention relates to a compact cosmetic container that is easy to recycle, and more specifically, to a compact cosmetic container that is easy to recycle in such a way that the upper surface can be easily separated from the side wall joint, thereby allowing the consumer to conveniently remove the upper surface during the recycling process, which improves recycling efficiency. Cosmetics are products applied to the outside of the human body to enhance appearance or maintain cleanliness. They serve various purposes, such as makeup, skin care, cleansing, and fragrance improvement, and accordingly, their forms and application areas vary. These cosmetic formulations are classified into liquids, gels, oils, creams, sticks, powders, and aerosols, and these formulations influence the structure of the container and the method of use. Emulsions are a mixture of oil and water used as creams or lotions, while sticks are solid forms that offer excellent portability. Cosmetic containers hold and preserve these various formulations, enabling consumers to use them safely and conveniently. The primary functions of cosmetic containers include protecting contents, preventing spoilage, maintaining hygiene, and providing ease of use, while their design and materials directly influence consumer experience and brand image. Accordingly, various structures have been developed, such as bottle, dropper, jar, tube, and compact types. Bottle and dropper types are suitable for liquid products, while jar types are primarily used for high-viscosity formulations like creams. Tube types are hygienic and easy to carry due to their squeezable design, and compact types are suitable for solid formulations due to their multi-functional structure that includes features such as pumps. Meanwhile, compact cosmetic containers often include a nameplate on the outer surface of the lid's upper section to display information such as the product name and logo. This nameplate serves to convey information while adding aesthetic appeal to the exterior by including the product logo or brand name. However, since nameplates are generally formed from a different material than the upper section to emphasize the aesthetic beauty of the exterior, recycling efficiency is reduced if the upper section with the nameplate attached is recycled along with the existing cosmetic container. In addition, a mirror is sometimes attached to the inner surface of the lid's upper section. However, since mirrors are generally composed of glass or composite materials, which differ in material from the upper section, recycling the entire upper section as is makes material separation difficult, thereby reducing recycling efficiency. Therefore, it is necessary to enable the top surface, to which the nameplate and mirror are attached, to be easily separated from the existing cosmetic container so that consumers can dispose of it separately. However, since the top surface of conventional cosmetic containers is formed integrally with the lid without a separate fastening means, it is difficult for consumers to separate it or remove it during the recycling process, which poses a problem of reduced recycling efficiency. These difficulties in recycling stem not only from the top surface but also from the structure requiring the entire container to be discarded once the cosmetic ingredients are depleted. Generally, once the ingredients in a cosmetic container are exhausted, consumers discard the entire container and purchase new products. This is because most cosmetic containers are designed to be difficult to reuse or recycle. To address this, refillable cosmetic containers have been developed that allow only the refill container filled with ingredients to be separated and replaced. However, conventional refillable cosmetic containers have a complex structure and are difficult to replace, making them difficult for consumers to use easily.
