Description

Operating pump for cosmetics vessel

The present invention relates to a pump structure of a cosmetic container installed in the openings of various cosmetic containers to discharge the contents by a predetermined amount by the pumping operation by the pressing operation, and more specifically, the assembly structure and manufacturability and lifting operation by simplifying the structure It improves the operability according to, and also to prevent the inflow of water from the outside while removing metal parts to prevent dilution, contamination, and deterioration of the contents in advance.

Generally, a cosmetic container for storing and storing liquid or gel cosmetics is provided with a pressurized pumping means called a dispenser to smoothly discharge the contents to the outside on the inlet.

The pump of the cosmetic container has a function of discharging the contents by a certain amount to the outside to promote convenience of use and to reduce waste by suppressing excessive discharge of the contents, and various structures have been proposed and widely used until now. have.

An alternative principle of the pump is that when the operation button is pressed with a finger, the contents inside the container are pumped by the pressing force generated by the operation thereof and discharged to the outside by a predetermined amount through the nozzle.

Looking at the pumping device of the conventional cosmetic container proposed as an example, it may be a utility model registration No. 187929 as shown in Figures 1 and 2 of the accompanying drawings.

The nozzle cap 2 is mounted on the inlet side of the container 1, and at the same time, an operation button 4 having a nozzle 3 is installed at the nozzle cap 2, and the operation is lifted by a pressing operation. Plunger 8 is coupled to the lower portion of the fluid passage pipe 5 is connected to the elastic support by the return spring (6) to discharge the contents to the nozzle (3) through the orifice (7), The outer diameter of the plunger 8 is fitted with a valve 10 which is tightly coupled to the inner diameter of the cylinder 9 and is operated, and a ball valve 11 for opening and closing the inlet 9a of the cylinder 9 is provided. have.

In addition, the flange 12 is formed in the lower portion of the return spring 6 in order to facilitate the opening and closing operation of the ball valve 11 at the same time the flange 12 is another ball 13 by the ball valve ( 11) is configured to be combined.

Accordingly, the plunger 8 connected by the fluid passage pipe 5 moves downward while compressing the return spring 6 in response to the pressing of the operation button 4, and the contents in the cylinder 9 are closed by the pressing force thereof. It is discharged to the nozzle 3 side through the orifice 7 between the 10 and the plunger 8.

At this time, the ball valve 11 is in a state in which the inlet port 9a is closed by the pressure in the cylinder 9 and the spring 13.

On the contrary, when the operation button 4 is released, the plunger 8, the fluid passage tube 5, the operation button 4, etc. are raised by the return force of the return spring 6, and the cylinder ( As the vacuum pressure is generated in 9), the ball valve 11 opens the suction port 9a, whereby the contents in the container 1 flow into the empty space in the cylinder 9 to await discharge.

However, in the conventional cosmetic container pump structure as described above there are a number of problems as follows.

First, the nozzle cap (2) and the operation button (4) is assembled by the fluid passage pipe 5 is fastened to a separate part in the lower center of the structure is not only complicated structure but also requires a lot of parts cost of manufacturing In addition to the rise, there is a disadvantage that the assembly and operability is not good.

In addition, they are not only assembled by fitting, but also the operation button 4 is supported by the fluid passage tube 5, so that the stable lifting force is not obtained during the lifting operation, so that the smooth lifting operation is expected. There is a difficult problem.

That is, since the force to press the operation button (4) is not always exactly vertical, the reduction of the pumping efficiency, of course, weakens the fixing force of the related parts, which is a factor of failure and shortening the life.

In addition, due to the above factors, water is easily introduced from the outside and mixed with the contents, thereby diluting the contents, thereby degrading performance and contaminating and altering the contents.

In particular, the pump is mainly used as a container for storing gel detergents, cosmetics, etc. due to its characteristics, for example, when used as a shampoo container, bubbles are generated when water flows in from the outside, and the contents are diluted to deteriorate the performance. Furthermore, there was a problem of contaminating and altering the contents.

In addition to the above problems, the return spring 6 or the ball valve 11 for returning the operation button 4 is installed on the passage through which the contents are passed. If the viscosity of the contents is high, the elasticity of the return spring (6) and the ball valve (11) is reduced, there is also a problem that causes a malfunction.

Therefore, the present invention has been made in consideration of the conventional problems as described above, the object of which is to simplify the structure of the cosmetic container pump to improve the manufacturability, assemblability and operability and to significantly reduce the manufacturing cost of the cosmetic container In providing a pump structure.

Another object of the present invention is to provide a pump structure of the cosmetic container to prevent contamination and deterioration of the contents by not using metal parts while preventing water from being mixed into the contents from the outside to the inside.

The present invention for achieving this object is achieved by improving the pump structure of the cosmetic container to a completely new structure, which is fastened by a nozzle cap to the opening of the storage container and the opening of the storage container by the tip tube A support body for guiding the contents to be sucked out, a valve body installed in the support body, having excellent circular restoration and elasticity, for opening and closing a passage according to the discharge of the contents, and lifting and lowering operation by being pushed to the support tube. And it is characterized in that it consists of an operation button to open and close the valve body to discharge the contents to the outside.
