In today's modern society, both men and women of all ages use cosmetics according to their needs in accordance with the rapidly diversifying trend of the times. In particular, in the case of women, various types of cosmetics and cosmetic products and tools with various colors is being used, and various high-quality cosmetic products and tools are being launched into the market day by day due to research and development by cosmetics-related companies.

The above cosmetics are manufactured with natural raw materials as interest in the stability of cosmetic compositions and skin beauty increases due to the improvement of living standards, but these cosmetics do not add preservatives in order to minimize irritation to the skin. As a result, it has a disadvantage that the risk of deterioration is relatively high compared to cosmetics made of chemical raw materials. For example, the cosmetics may be contaminated or deteriorated due to penetration of bacteria due to contact with external air during use or oxidation of the composition due to contact with air.

In addition, by using a container having a simple opening and closing function in order to store and use cosmetics having a liquid or gel form such as lotion, cream, gel, shampoo, rinse, etc. among the cosmetics, the cosmetics from the container with a spatula or It was used by taking it off with a finger and applying it to the skin or hair, but such a conventional container had a problem in that the cosmetic was wasted because the amount of the cosmetic discharged was not always constant.

Accordingly, a pump-type cosmetic container has been developed that minimizes contact between cosmetics and external air, is convenient to use, and can constantly adjust the discharge amount of cosmetics. It is provided in the opening of the pressurized pump and is configured to include a nozzle head coupled to the upper part of the container body in a state connected to the pressurized pump, and when the nozzle head exposed to the outside is pressed downward, the pressurized pump The contents accommodated in the container body are discharged to the outside by a predetermined amount by the pumping operation.

On the other hand, in recent years, there are many cases in which two or more different contents are mixed and used in order to double the efficacy or effect among cosmetics or pharmaceuticals accommodated in containers.

However, when the contents mixed and used as described above are mixed from the beginning and stored together in one container, and then distributed or stored, a chemical reaction occurs inside the container, and the contents solidify or precipitate, resulting in poor discharge or discoloration of the contents. Or, a problem of deterioration may occur. For this reason, in the prior art, after storing the contents of different components in different containers, when using them, the user discharges the contents and directly mixes them for use, or the different contents are stored in separate containers and then used in two containers. A method of opening each inlet and mixing in a separate container has been proposed, but this method has problems in that the user has to directly mix and use the contents stored in a separate container, the risk of loss, and poor portability. .

Therefore, a dual-type cosmetic container has been developed in which different types of contents are isolated and stored in one container, and then discharged at the same time by a user's operation when necessary so that they can be mixed and used.

As such a prior art, a cosmetic container of Republic of Korea Patent Registration No. 10-1446612 has been disclosed. The prior art includes a first container containing a first composition and a second container containing a second composition, and a container portion formed by combining the first container and the second container in a cylindrical body, and a first container mounted on the first container. The first airless pump module, the second airless pump module mounted on the second container, the first pressing cap mounted on the first airless pump module and having a first discharge hole, and the second airless pump module mounted on the second discharge hole As a cosmetic container composed of a pressing part composed of a second pressing cap having a, two contents are accommodated in each container, and the two contents are discharged and used by individually or simultaneously pressing the pressing cap connected to each container.

However, the prior art has a disadvantage in that only one composition is quickly exhausted and the remaining composition remains as a residual amount when used individually by pressing each pressing cap.

In addition, in the prior art, when the first pressing cap and the second pressing cap are simultaneously pressed to discharge the composition contained in the first container and the second container at the same time, the user presses the first pressing cap and the second pressing cap through the fingers. There was an inconvenience in use that had to be pressed with considerable force, and it was difficult to replace the first container and the second container because it did not have a separate refill structure. There was a problem with wastage.

Therefore, it has become necessary to develop a cosmetic container in which a plurality of dispensing means are smoothly operated at once by pressing a push button and the contents container can be easily refilled.
