Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to an aerosol container suitable for use in removing internal liquid little by little.

[Conventional technology and its problems]

Aerosol containers use pressurized gas sealed in the container to eject the internal liquid, and are operated by pressing down on the push button on the top of the main body of the container, so if you want to take out the internal liquid in small, fixed amounts, For example, it is inconvenient for cosmetic liquids to be received in the hand and sprayed until the required amount is reached each time.

[Means for solving problems]

In contrast, this invention has a structure in which a hollow portion having a predetermined volume is provided within the push button, and only the stored liquid is spouted into this hollow portion.

[Example of idea]

An example of this invention will be explained with reference to the drawings.
As shown in FIG. 1, a valve stem 4 is provided together with a spring 5 and a valve ring 6 in a valve housing 3 attached to the lower surface of the top plate 2 of the main body 1 of the container. This device is similar to the conventional device in that when the stem 4 is pushed down against the spring 5, the valve ring 6 is bent downward and a flow path leading to the spout of the push button 7 is opened, but in this invention, The push button 7 is made in a hollow shape, and has a riser pipe 8 inside, whose upper end is fitted into a cylinder portion 9 that projects on the inner surface of the upper end of the push button, and whose lower part is made of soft rubber provided inside the lower end of the push button 7. It is inserted and fixed into the center hole of the elastic disk 10 made of
The lower end of this riser pipe 8 is connected to the valve stem 4 . This elastic disk 10 always maintains the push button 7 in a raised state relative to the valve stem 4 due to its elasticity, and also functions as a gasket to keep the inside of the push button airtight.

Next, the cylinder part 9 provided on the push button 7
One end of a flow path 12 leading to the jet nozzle 11 is opened on the inner surface, and an O-ring 13 is located near the upper end of the riser pipe 8 and slightly below one end of the flow path 12.
is fitted, and a through hole 14 that communicates with the inside of the push button 7 is opened at a proper intermediate position. In the figure, 15 is a sealing member for the riser pipe 8 provided in the inner part of the cylinder portion 9, and 16 is a circular bottom plate fitted to the lower surface of the push button 7.

This device has the above-mentioned structure, and when the push button 7 is sufficiently depressed as shown in FIG. 2 from the unused state shown in FIG. 8, but also descends into the flow path that opens on the inner surface of the cylinder part 9, and the opening is blocked by the O-ring 13 of the riser pipe 8, so that the internal liquid that has entered the riser pipe 8 does not pass through. It passes through the hole 14 and fills the hollow part of the push button 7 and is stored therein.

Next, when you release your finger from the push button 7 and the state is similar to that shown in FIG. One end of the flow path 12 that rises and leads to the spout 11 is opened from the O-ring 13 of the riser pipe 8, and the stored liquid filling the cavity passes through the flow path 12 and reaches the spout 11.
It is injected from the beginning and stops naturally after a certain amount of injection is completed.

[Effects of the invention] As described above, in this invention, by pressing the push button 7 and applying the spout 11 to the desired area, and then releasing the finger from the push button 7, the water is stored in the push button 7. It is extremely convenient because a fixed amount of internal liquid can be sprayed onto a required area over a fixed period of time, and since the overall shape of the sprayer is similar to a normal sprayer, the spraying operation is easy. Furthermore, if the spring 5 that raises the valve stem 4 has a spring pressure weaker than that of the elastic disk 10 that raises the push button 7 relative to the riser pipe 8, the push button can be lowered in two stages. Press down the push button 7 against the weak spring 5,
If the elastic disk 10 is kept in the state shown in FIG. 1 without being deformed, the valve stem 4 will be lowered, and the liquid in the container body 1 will flow into the riser pipe 8 and continue through the flow path 12 to be sprayed. It is injected from the outlet 11.

Continuous spraying can be performed by slightly depressing the push button 7 against the weak spring.

Claims (1)

[Scope of Claim for Utility Model Registration] In an aerosol container, a valve stem that passes through the top plate and has a push button 7 at its upper end is inserted into a valve housing provided on the lower surface of the top plate so as to be able to move up and down, and the lower end is inserted into the push button 7. The riser pipe 8 connected to the upper end of the valve stem 4 is inserted into the cylinder part 9 which is vertically disposed on the inner surface of the upper end of the push button 7, and the lower part thereof is inserted into and held by the elastic disc 10 which covers the lower part of the push button 7. At the same time, one end of the flow passage 12 leading to the spout 11 of the push button 7 is opened on the inner surface of the cylinder portion 9, and the flow passage 12 is opened in the riser pipe 8 in accordance with the pressure of the push button 7. An aerosol container characterized in that an O-ring 13 that closes one end of the container and a through hole 14 that constantly communicates with the internal cavity of the push button 7 are provided.
