Description

Pumping valve assembly for aerosol spray

The present invention relates to a pumping valve assembly for aerosol spraying, and more particularly, a solid sealing structure of a pumping valve coupled to a container cap and double the sealing force is increased by the pressure of the gas, as well as general purpose regardless of the shape and shape of the container It relates to a pumping valve assembly for an aerosol spray that is easily applicable and easy to manufacture.

In general, a spray is a generic term for all devices that are used by ejecting a certain amount of the contents in a fluid state, such as a chemical solution, a cosmetic solution, etc. filled in a sealed housing.

Although various types and methods have been developed for the form of spray as described above, the general spray operation method is that the spray generates pressure due to the action of an internal spring, etc. It is a method of discharging by pressing and pressure.

The above method complicates the shape of the spray and increases the cost, and also does not guarantee sealing inside the housing, and there is a limitation in the pressure level generated by the spray, so that the contents cannot be discharged with high pressure. .

In order to improve the above disadvantages, various types of spray have been developed, and a method of discharging the contents inside the housing by applying pressure in a different way than the above general spray has been developed.

As a prior document for improving the above disadvantages, through the Korean Dongrok Utility Model No. 20-0383512, a device capable of smoothly ejecting the filled contents due to the action of air pressure or the self-contracting force and air pressure of the inner container has been disclosed. .

In addition, Republic of Korea Patent Registration No. 10-0486015 provides a device capable of ejecting fluid by air pressure and capable of ejecting fluid by self-contracting force together with air pressure in order to solve such a problem.

As shown in FIG. 1, the valve structure used in most sprays together with the above-mentioned spray consists of an outer cylinder, a fixture, a valve, and a push button.

The outer cylinder has a cylindrical shape with an open top. Here, the open upper part of the outer cylinder is formed in a radially narrow step shape as it extends upward. The fixed body is coupled to the upper part of the outer cylinder, and a valve is installed on the fixed body to seal the outer cylinder.

The ring shape of the fixing body is made of a metal plate, and has a step shape that is radially narrower as it extends upward. Preferably, the lower end of the fixture is fitted and fixed to the outside of the upper end of the outer cylinder. A valve installation hole communicating with the inside of the outer cylinder is formed on the upper surface of the fixture, and the valve is installed.

In the valve, a cylindrical body with a hollow inside is coupled to the inside of a fixed body, and similarly, the hollow inside of the valve body enters and exits the body from the upper part of the body, and on the outer circumferential surface of the valve body, an orifice pipe that penetrates into the hollow inside this is formed A spring is disposed at the lower portion of the valve body so that the valve body is elastically supported, and a packing for intermitting the orifice pipe is disposed on the outer side of the valve body. A push button for operating the valve is coupled to the upper portion of the valve formed in this way.

The push button is inserted into the upper portion of the valve body and is formed so that a discharge pipe communicating with the hollow inside of the valve body is opened to one side of the push button. And the outlet of the discharge pipe is equipped with a nozzle for spraying the ejected contents.

Briefly describing the operating state of the dispenser formed in this way, after filling the inside of the outer cylinder with the contents and air pressure, the user presses the push button to spray the contents with the nozzle. First, when the push button is pressed, the valve body is pressed downward, and the packing that has blocked the orifice tube is released. Therefore, the contents filled inside the outer cylinder rises on the straw at the same time as the orifice tube is opened and is ejected through the hollow inside of the body.

However, there is a problem that the spray is difficult to use in products that need to be sprayed with very fine particles, such as hairspray, because the amount of air pressure is small.

On the other hand, Japanese Patent Laid-Open No. 2008-155525 discloses an aerosol composition for a mold release agent and an aerosol injection device for applying the same, but the Japanese Patent Application Laid-Open No. 2008-155525 discloses that the gas in the aerosol container for industrial use is 60v% of the total volume Although the product pressure is set to 04~08MPa at 25 degrees Celsius, there was a spray that sprayed in the reverse direction, that is, the injection port was directed downwards, but it is difficult to maintain the pressure properly, so the injection valve that can smoothly perform the reverse injection The need for a lower filling spray and the need for a spraying device for smooth spraying have been raised.

At this time, the content is introduced into the hole 21a of the valve body 21 by the pressure of the gas, and flows into the flow path 21b through the space where the ball 27 is located, and the inlet hole 23- of the pumping rod 23 2) and the ejection hole (23-1) is ejected from the ejection hole (13a) of the push button (13).

When the pressing state of the push button 13 is released, the pumping rod 23 moves upward by the spring 25, and at this time, the leak-proof packing 24 is combined with the pumping rod 23 and the inlet hole ( 23-2) is closed to cut off the supply of the contents.

Since the inlet hole 23-2 is closed by the leak-proof packing 24, the content supplied through the supply pipe by the pressure of the gas is stopped, and at this time, the leak-proof packing 24 is attached to the pumping rod 23. In the coupled state, the space between the valve body 21 and the valve cap 26 is sealed.

As described above, when the contents are jetted, there is an advantage that the contents are easily jetted even when the container is in a normal position or in an upside down state, so that there is no inconvenience in use.

And the present invention prevents leakage of the contents and gas contained in the container by increasing the sealing force by the pressure of the gas and the solid sealing structure of the pumping valve 20 coupled to the container cap (10).
