Description

CROSS-REFERENCE TO RELATED APPLICATION

This application claims the benefit of Korean Application No. 10-2013-0110927, filed on Sep. 16, 2013 with the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a refillable cosmetic container, and more particularly, to a refillable cosmetic container that can be simply refilled with an inner housing keeping a substance.

2. Description of the Related Art

In general, various refillable products that allow customers to purchase and use commodities at low prices have been put on the market.

In those refillable products, there are refillable products that are refilled with a substance in the original container and refillable products that are refilled with an inner container keeping a substance in an outer container.

The products that are refilled with a substance in the original container may be bath articles and detergents and the products that are refilled with an inner container including contents in an outer container may be cosmetics.

In Korean Utility Model. No. 282756, titled ‘A case of cosmetic for replace’, an inner container keeping a substance is put from under into an outer container with an open bottom and a cap is coupled to a thread on the outer side of the lower portion of the outer container, so the inner container is retained in the outer container.

As described above, by putting an inner container into an outer container in one container and, not by refilling the outer container with a substance, but by putting the inner container into the outer container for refilling, it is possible to refill lotion and skin toner that are basic cosmetics requiring cleanliness. Further, designs can be freely changed by outer containers, so it is possible to always provide new commodity images to customers and to provide cosmetic customers with relatively expensive cosmetics at low prices.

There is a prior art document having these advantages, in which a cap for keeping a refilled inner container is thread-fastened to an outer container. However, there is a problem in this configuration that it takes long time to separate and couple the cap to refill the inner container and the inner container cannot be put into the outer container due to friction of the thread if the cap is not accurately coupled to the outer container.
