The present invention relates to a pumping device for discharging the contents of the cosmetic container, specifically, prevents expensive cosmetic contents from being rancid, and even when only a small amount of contents remain, the discharge amount can be used to the end without change. This very simple not only can reduce the manufacturing cost but also relates to the pumping device of the cosmetic container without the worry of trouble.

Cosmetic containers used to fill various cosmetics in gel or cream formulations, especially containers used in cosmetics which are distributed at very high cost by containing functional ingredients such as anti-wrinkle ingredients, whitening ingredients and sunscreen ingredients, It is common to use an airless type, i.e., a vacuum-storage pumped dispensing vessel, in order to avoid possible rancidity with as little contact with air or light as possible.

As for such a pumping discharge container or a pumping device used therein, various structures have been proposed and widely used. The pumping device for cosmetic containers of the most common structure, as shown in FIG. The nozzle cap 1 is fastened to the upper portion, and the upper portion of the nozzle cap 1 is configured with a pressing head 2 for lowering and lifting, respectively, by the user's pressing operation and the elasticity of the elastic member 7. One outside surface of the head (2) is configured with a nozzle (3) for outflow of contents, and in the lower portion of the center of the pressurizing head (2) an outflow pipe (4) through which the contents of the cylinder (8) flow out into the nozzle (3) It is constructed integrally or glued, the end of the outlet pipe (4) is configured with an orifice (5) for introducing the contents inside the cylinder (8) for delivery to the outlet pipe (4), the end of the outlet pipe (4) Pushing pressure on outer surface in close contact with inner surface of cylinder (8) The pressurizing flange 6 is configured to deliver the contents in the cylinder 8, and an elastic member 7 is connected to the lower side of the pressurizing flange 6 of the orifice 5 to lift the orifice 5 after pressing. And a cylinder 8 having a portion of the distal end of the outlet pipe 4 and the orifice 5 and the elastic member 7 and having a lower end thereof narrowed, wherein the cylinder has a narrow portion at the lower end of the cylinder 8. (8) A ball valve 9 is configured to open and close according to a pressure difference between inside and outside.

In addition, the cosmetic container using such a pumping device, the piston (P) for transmitting the atmospheric pressure when the pressure flange 6 rises by the elastic member 7 to the contents in the container to the inner surface of the lower end of the container (V). It is comprised in close contact.

The general pumping discharge container configured as described above is caused by the pressure generated when the user presses the pressurizing head 2 and the outlet pipe 4 and the orifice 5 connected thereto are lowered and the pressurizing flange 6 is lowered together. The contents flow out through the orifice 5, the outflow pipe 4, and the nozzle 3 in sequence, and when the user releases the pressure head 2 after the required amount of discharge, the orifice 5 is caused by the elastic force of the elastic member 7. And the outlet pipe 4 and the pressure flange 6 connected thereto are operated in such a way that the ball valve is opened and the contents of the container V are introduced into the cylinder 8 by the vacuum pressure generated by the rising. When the head 2 is raised, atmospheric pressure is transferred to the piston P and raised together.

However, such a conventional pumping discharging container has an outlet pipe 4 connected to the lower portion of the pressurizing head 2, and is connected to the orifice 5, the pressure flange 6, the elastic member 7, and the cylinder. (8), the ball valve (9) is composed of a complex connection is not only difficult to manufacture itself, but also had a disadvantage that takes a lot of manufacturing costs.

In addition, since the elastic member 7 should be provided inside the cylinder, the size of the elastic member 7 should be relatively small, so that the pressure for raising the pressure flange 6 and the pressure head 2 connected thereto after pressing may be weak. Since the elastic member 7 which is mainly a metal material is provided inside the cylinder in contact with the contents, there is a problem that the contents are contaminated or deteriorated by the metal material.

Above all, the conventional general pumping discharge container configured as described above is configured to penetrate through the inside of the cylinder 8 and the orifice 5, the outlet pipe 4, and the nozzle 3, so that a relatively large amount of contents can be obtained. As it can be said that it is exposed to the outside air as it is, there was a problem that a certain amount can be in a state where the rancidity always.

In addition, since the cylinder 8 is provided to protrude downwardly in the center of the container V so that the piston cannot rise above a certain height, when the cosmetics are manufactured by fully filling the contents during the first production, the container ( V) Despite the relatively large amount of contents remaining inside, there was also an uneconomic problem that should be discarded as it is not discharged by pressurization.

In addition, even in the case of manufacturing by properly adjusting the amount of content to be filled during the initial production in consideration of this, the space in the container beyond the lower end of the cylinder (8) becomes an unnecessary space from the beginning, resulting in the effect of wasting materials and parts There was also a problem.

On the other hand, the prior art for overcoming the above disadvantages of such a general pumping discharge container can be found in the technology of the patent / utility model, for example, in the Republic of Korea Utility Model Registration No. 3460177, The lower part of the piston member holder mounted in the housing has a liquid collection chamber having a liquid inlet hole, and the center shaft has a recess having a slanted stepped jaw, a supporting jaw and a liquid suction hole, and a recess having an opening and closing part for opening and closing the liquid inlet hole. The elastic pumping member to be fitted has a hole in which the inner wall surface opens and closes the liquid suction hole in a flat part, and has a cylindrical support formed integrally with the piston member to form a container, so that each time the nozzle head is pressed, the contents pumping main part Is lowered by a predetermined distance, and the indoor object is discharged as much as the lowered distance. Attempts have been made to allow the nozzle head to no longer lower and to allow quantitative discharging by closing it by means of closing.

In addition, the Republic of Korea Utility Model Registration No. 282747 is formed so that the fluid passage tube integrally formed in the lower portion of the operation button to have the function of passing the fluid and the guide function according to the lifting operation at the same time, the lower end of the fluid passage tube An attempt has been made to prevent the contamination and deterioration of the contents and to improve the pumping efficiency as a whole by forming the container so that it can be easily fitted on the nozzle cap by forming the locking step.

However, such prior art in the patent / utility model also has a number of problems, for example, by configuring a complex structure such as an outlet pipe, a cylinder, a ball valve that is formed to protrude into the container from the center lower portion of the container cap Not only is there difficulty in the production itself, but it is uneconomical because the production cost is high, and the protruding structure as described above results in an uneconomical effect of wasting resources by reducing the amount of actually available contents compared to the contents of the container. Even if the elastic member or the spring is configured to not directly contact the contents, the relatively large amount of the content is still exposed to the outside air, so that a certain amount of the content is always placed in a rancid environment. I still had problems.

The present invention is to overcome the problems of the prior art, the purpose is that there is no fear that the contents are contaminated or deteriorated by not using the elastic member of the metal material, the head structure for discharging is simple and compact and relatively many Since the amount of contents is not exposed to the outside air as it is, it is possible to prevent the contents from being placed in a dispersible environment as much as possible, and to remove components that protrude downwardly in the center of the container (V) such as a cylinder. In the case of producing cosmetics by filling up the contents at the time of the first production, despite the relatively large amount of contents still inside the container (V), it is no longer discharged by pressurization and thus does not cause an uneconomic problem to be discarded as it is. To provide a pumping device for a new cosmetic container to be.
