The present invention relates to a cosmetic pump, and more particularly, by forming an elastic body made of a synthetic resin material on the inside and outside in a double layer to improve elasticity and repulsion, the synthetic resin elastic body that allows the pumping operation to be performed more smoothly is provided. It relates to a cosmetic pump provided with a double.

Cosmetics refer to articles used on the human body to clean and beautify the human body to add attractiveness, change appearance, or maintain or promote the health of skin or hair.

If the above cosmetics are classified according to the purpose of use, facial cleansing cosmetics used to remove sebum, impurities and contaminants on the skin surface, basic cosmetics used to properly supply moisture and oil to the skin, and to express beautiful colors. It is classified into color cosmetics used, hair cosmetics used to protect hair and supply nutrition while removing foreign substances from the hair or scalp, and perfumes used to exude fragrance to others by dissolving fragrances in alcohol.

As the above cosmetics are developed, it is necessary to develop various cosmetic containers that can contain cosmetics.

In general, to store and use cosmetics in liquid or gel form, such as lotions, creams, gels, shampoos, rinses, etc., conventionally, by simply using a container having an opening and closing function, the cosmetic material from the container is spatula or It was used by taking it off with a finger and applying it to the skin.

However, the conventional cosmetic container has a problem in that the amount of cosmetic material to be discharged cannot be constantly adjusted, and thus the cosmetic material is wasted.

In order to solve the above problems, a cosmetic pump has been disclosed as Korean Patent Registration No. 10-1376050, wherein the conventional cosmetic pump includes a housing constituting the exterior of the pump, and a fixed bushing fixedly coupled to the upper portion of the housing. , A piston support vertically moving within the housing, a piston fitted outside of the piston support and vertically moving together with the piston support, a stem coupled to an upper portion of the piston support and pressed by a button, and elastically supporting the stem It is composed of a spring, and when the cosmetic pump is pumped by the pressure of the button, a fixed amount of content is discharged to the outside.

However, the conventional cosmetic pump has a problem of increasing the manufacturing cost of the pump because the spring is made of a metal material. In addition, since the pump is made of heterogeneous materials of synthetic resin material and metal material, it has to be separated and disposed of for recycling, and thus there is a problem that recycling is not easy.

In order to solve this problem, a spring structure of a pumping container has been disclosed in Korean Patent Laid-Open No. 10-2016-0097607, and the prior art is installed to surround a stem that moves together according to the vertical movement of the button part and is coupled to the lower part of the button part. In the spring structure of a pumping type container that provides an elastic force in an upward direction to enable repetitive pumping of the pumping member through the part, the spring is made of a synthetic resin material, and the lower support and upper support of a ring shape, and the lower support and It is formed connected between the upper support and elastically deformed according to whether the button portion is pressed, and includes a pair of elastic bodies formed in a spiral shape to induce a pumping operation of the pumping member.

However, in the prior art, the spring is composed of a lower support, an upper support, and a pair of helical elastic bodies connecting the upper and lower supports to support the pumping member, and when the button is pressed, the pair of helical elastic bodies presses the button part. The structure is inclined to one side at the same time and then restored, so there is a limitation in that the elasticity and repulsion force are lower than that of the conventional metal spring.

Accordingly, there is a need to develop a pump having an elastic body made of synthetic resin, which is easy to recycle and does not lose elasticity and repulsion compared to a conventional pump equipped with a metal spring.
