Description

Container with different types of materials using pump}

The present invention relates to a container, and more particularly, to a pump type heterogeneous content container that can be used by separately discharging each of the heterogeneous contents in one container.

Since most of the conventional cosmetic containers are configured to store one cosmetic product, if you want to mix and use different types of cosmetic products, you must mix and use the cosmetic products contained in each cosmetic container in the state of discharging them in the palm of your hand. There is a very cumbersome problem.

In general, cosmetics are in various forms such as powder, liquid, gel or cream, and solid, and these cosmetics are stored and used in separate containers.

Recently, among cosmetics used by women, makeup techniques in which users directly mix and use different types of cosmetics have been proposed, and as cosmetics are subdivided and their functionality is enhanced, these makeup techniques are gradually spreading.

In the case of functional cosmetics, raw materials mixed with various active ingredients in advance are accommodated in a container and then used by discharging the required amount. In the case of functional cosmetics, functional ingredients such as vitamins or natural extracts, which have excellent functions such as wrinkle relief and whitening, are often used.These functional ingredients can easily deteriorate according to changes in the surrounding environment, for example, temperature or humidity. . In addition, when raw materials containing vitamins or natural extracts are mixed with other liquid cosmetics in advance, the possibility of oxidation and deterioration may increase. Moreover, cosmetics with high availability of vitamins or natural extract raw materials have a high possibility of oxidation and deterioration due to contact with air, exposure to UV rays, and penetration of foreign substances, and therefore, the shelf life or period of use is generally shorter than that of general cosmetics.

Therefore, as a way to prevent consumers from using products that are likely to have deteriorated due to a long period of use, manufacturers also shorten the period of use by reducing the unit packaging capacity of functional cosmetics. In addition, by storing them separately in each container, it is possible to prevent the possibility of deterioration while protecting the function of the active ingredient contained in the functional cosmetic and increasing the persistence of the effect.

However, in order to mix and make up different types of cosmetics, it is not only cumbersome to carry the cosmetics stored in each container, but it is also cumbersome to discharge and mix cosmetics stored in each container.

In addition, pump-type containers are widely used as containers for discharging viscous contents such as cosmetics.

For example, in U.S. Patent No. 4,511,068, a piston is installed to be slidable on the upper cylindrical wall of the container, and an inward flange is formed on the upper end of the center pipe while surrounding the upper end of the piston center pipe, and between the center pipe and the inward flange. An extrusion container has been introduced that allows the contents to be extruded in only one direction by installing a valve so that the piston moves up and down by spring elastic force.

However, in this type of extruded container, the force to which the valve is subjected to atmospheric pressure is weakened by the contents remaining at the outlet after the contents are extruded, so a certain amount of time is required for the valve to close, and the container body is not in a vacuum state after the piston is raised. In order to extrude the contents again, there is a problem in that the vertical movement of the piston must be repeated several times. In addition, there is also a problem in that assembly is difficult because the number of peripheral parts for vertical movement of the piston is large, and a spring and a tubular outlet member for supporting the spring are required.

The ventilation hole 531 may be configured in a form in which the diameter decreases from the outside toward the inside. In this case, the pumping means 530 is deformed when pressurized, and the end of the ventilation hole 531 is blocked so that the air pressure is easily transmitted. When the pressure is released, the outer end of the ventilation hole 531 is easily opened, so that air can be quickly introduced into the pumping means 530.

As described above, the heterogeneous contents container using the pump according to the present invention can be individually discharged by the pumping operation of the heterogeneous contents, and the contents can be discharged constantly by preventing the retraction of the piston by the check valve. . Those skilled in the art to which the present invention pertains will be able to understand that the present invention can be implemented in other specific forms without changing the technical spirit or essential features thereof. Therefore, the above-described embodiments are illustrative in all respects and should be understood as non-limiting. The scope of the present invention is indicated by the claims to be described later rather than the detailed description, and all changes or modified forms derived from the meaning and scope of the claims and equivalent concepts should be interpreted as being included in the scope of the present invention.
