Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a cartridge-type rod-shaped cosmetic dispensing container.

Conventionally, many cartridge type cosmetic stick dispensing containers have been used in which solid cosmetic sticks such as eye shadow, eyeliner, eye makeup, foundation, etc. can be attached to and detached from a container body equipped with a dispensing mechanism. Since the core of most cosmetics has poor viscosity, lacks elasticity, and is soft, it has been extremely difficult to use the cosmetics without accidents such as breakage.

For this reason, the core of the above-mentioned cosmetic is housed in a cartridge cylinder,
Cartridges of this type are often used to replace the core at the same time as the IJ cartridge, but when replacing the core, the cartridge barrel is attached to and removed from the container body while at the same time holding the core. The chuck must be attached to and detached from the end of the feeding mechanism of the container body, which has the disadvantage of complicating the replacement procedure and complicating the structure.

The present invention has been made in view of the above-mentioned drawbacks and has been made for the purpose of eliminating the above problems, and provides a cartridge-type bar-shaped cosmetic container whose cartridge cylinder is easy to replace, whose structure is simple, and which can be securely fastened. The purpose is to provide
