Description

Cosmetic container and method of manufacture the same The present invention relates to a cosmetic container and a method for manufacturing the same, and more specifically, to a cosmetic container having a structure capable of effectively discharging a contained cosmetic with a small amount of force and a method for manufacturing the same. Cosmetics can be stored in various forms and provided to users. Among commonly used cosmetics, there are forms provided in liquid form, which are supported (or impregnated) on a carrier (or impregnating material, hereinafter referred to as the carrier). Users can apply pressure to the carrier to discharge the supported cosmetic to the outside for use. The carrier is typically formed from a porous material. The cosmetic is contained within the pores and is discharged to the outside by the pressure when the carrier is pressurized. The carrier must be configured to stably contain the cosmetic when not pressurized and to discharge the cosmetic upon pressurization. However, the structure required to stably maintain the loaded cosmetic and the structure required to facilitate its release are generally in conflict. Therefore, most carriers currently on the market are formed with a structure that leans toward one of these two requirements. Korean Registered Patent Document No. 10-1963142 discloses a cosmetic container. Specifically, it discloses a cosmetic container that is forcibly formed into a shape containing contents containing cosmetics using a mesh net. However, cosmetic containers with this structure require an additional mesh net to forcibly change the shape of the contents. In addition, since the contained cosmetic must pass through the mesh net during the discharge process, it may be difficult to discharge the cosmetic smoothly. Korean Published Patent Document No. 10-2019-0038079 discloses a cosmetic product. Specifically, it discloses a cosmetic product in which the upper and lower parts of an impregnating material impregnating a content are compressed to form a density in the central part lower than the density of the remaining part. However, this type of cosmetic requires an impregnating material of a new shape, rather than the conventionally used impregnating material. In other words, the cosmetic according to the aforementioned prior art uses a custom-made impregnating material, making it difficult to use an impregnating material of the existing structure. Furthermore, the aforementioned prior art fails to provide a method for stably maintaining the position of the impregnating material.
