Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an aerosol dispensing device, which can dispense cosmetic creams, liang creams using a mixture of two components, hair styling products, two-component hot shaving creams, etc. in one use. It is used when dispensing only small amounts.

Aerosol products use the pressure of the propellant to atomize the contents in an atomized or foamy state, and have the effect of efficiently dispersing a small amount of contents, as well as having extremely excellent airtightness, and this airtightness is completely inhibited. It has the effect of allowing you to take out only the required amount of contents without any trouble. Other containers, no matter how airtight they are, have the disadvantage that the contents inside the container come into contact with air when the contents are taken out, and 4. It was not possible to expect the effect of preventing deterioration of the transferred contents. Therefore, it is possible to use the target product as an aerosol product, but if you try to dispense the aerosol contents into a regular container, it will scatter due to the ejection pressure and cannot be stored, especially hot shaving cream, hair dye, etc. It has been difficult to obtain accurate mixing ratios for the contents of two-liquid mixtures such as . The present invention eliminates the above-mentioned drawbacks, and allows the aerosol contents to be dispensed in a single dose without causing any scattering or the like.
An embodiment of the present invention will be described below with reference to the drawings. Reference numeral 1 denotes a stem of an aerosol container, which is connected to a valve mechanism and is pressed to open the valve and lead out the contents from the outlet passage 2.

Reference numeral 3 denotes a main body having an insertion opening 4 formed on one end surface into which the stem can be inserted in and out, and a mounting opening 5 communicating with the insertion opening 4 formed at the upper end.

Reference numeral 6 denotes a fixing device having a horizontal U-shaped cross section, in which the outer circumferential wall 7 and the bottom wall 8 of the mounting opening portion 5 are fixed in contact with each other, and is made of metal material, hard synthetic resin, etc., and has an insertion hole 9 in the center thereof. are doing.

Reference numeral 11 denotes an introduction valve which is inserted into this insertion port so as to be able to move forward and backward.One end forming an introduction path 12 for the aerosol contents is brought into contact with the upper end of the stem 1 to fit into the outlet path 2 of the stem, and an introduction path is formed on the side. A lead-out hole 13 suitable for the gasket 12 is bored, and this lead-out hole 13 is normally closed with an end face of a gasket 14.

Numeral 15 is a spring that engages with the locking collar 16 of the introduction valve 11 and urges the introduction valve 11 in the direction of the stem 1. The spring 15 is made weaker than the pushing spring of the aerosol container that presses the stem, thereby increasing the pressing force. have.

17 is the lower wall 18 of the fixed odor 6 via the gasket 14.
With the annular collar of the introduction chamber 19 softened, the side wall 2 of the introduction chamber 19
0 and the trim 21 cover the spring 15 and the other end direction of the introduction valve 11, and form a movement interval 23 of the introduction valve 11 at a distance between the pond end surface 22 of the introduction valve 11 and the inner surface of the end wall 21. .

Reference numeral 24 denotes an outlet formed in the side wall 20 of the introduction chamber 19, which faces the collision wall 28 at the lower end of the container 27, which is located on the outer periphery of the side wall 20 with an appropriate discharge interval 26 in between.

It is preferable that the collision wall 28 is formed so as to intersect at right angles to the flow direction of the contents flowing out from the outlet 24, and the end of the collision wall 28 is connected to the upper surface of the annular ring 17 with an interposed gasket 29. through the battle layer and the collision wall 28
An annular protrusion 31 is protruded from the outer end surface of the engaging flange 30 formed on the outer periphery of the end, and the container 27 is fixed by removably joining the protrusion 31 to the groove on the inner surface of the fixed odor 6. It is configured so that it can be separated from the odor 6 and used for washing. Reference numeral 32 denotes a housing portion of the housing body 27 formed above the discharge gap 26, which stores the ejected aerosol contents and uses them according to the purpose of use.

In the configuration as described above, the inlet valve 11 is connected to the stem 1.
When the main body 3 is pressed in the direction of the stem 1, the pressure spring becomes weaker than the pressure spring composing the valve mechanism of the aerosol container, and the introduction valve 11, which is under pressure by the pressure spring 15, is pushed up by the stem 1. The other end surface 22 is moved to the edge adjustment 21 of the introduction chamber 19.

Due to this movement, the outlet hole 13 is released from the seal of the gasket 14, and the introduction chamber 19 and the introduction path 12 are opened. If the main body stem is further pushed in the 1 direction, the introduction valve 11 will open into the introduction chamber 1.
9, the stem 1 is pressed against the end wall 21 of the aerosol container, and the valve mechanism of the aerosol container is opened, and the contents are transferred from the outlet passage 2 to the introduction chamber 1 through the introduction passage 12 and the outlet hole 13.
After being introduced into the container 9, the contents are ejected from the outlet 24 and collided with the collision wall 28. Due to this collision, the propellant dissolved in the contents is separated from the contents, ascends the discharge gap 26, and is discharged into the atmosphere. The pressure of the contents disappears due to the separation of the propellant, and the contents that continue to flow out in the discharge interval 26 push up to the storage section 32, which is collected with fingers, a brush, etc., according to the purpose of use. can be used.
Furthermore, when the pressing force on the stem 1 is released, the introduction valve 11 is restored to its original position by the restoring force of the spring 15 and becomes closed, so that the contents stored in the storage portion 32 will not flow out. In the above-described embodiment, the introduction valve 11 is formed separately from the stem 1, but in other different embodiments, it is also possible to use the weaving direction of the stem 1 as the introduction valve 11a.

That is, a cylindrical covering gasket 33 with a bottom is provided in the introduction chamber 19.
The opening 34 of the covering gasket 33 is closed in the direction of the insertion opening 9, and the pressing end surface 35 is pressed against the surface of the gasket 14 by the spring 15 in an airtight manner.
An opening 34 is formed in the covering gasket 33 thus formed.
Insert the introduction valve 11a portion of the stem 1 through. For this insertion, the end face of the introduction valve 11a is sloped so that the end face does not cover the covering gasket 33, or a notch 36 is formed in the end face of the covering gasket 33 or the introduction valve 11a. With this structure, when the main body 3 is pressed, the covering gasket 33 is moved against the inlet valve 1 against the restoring force of the spring 15.
1a pushes up, and after the pressing end surface 35 of the covering gasket 33 separates from the surface of the gasket 14, when it hits the end wall 21 of the introduction chamber 19, the stem is pushed down and the valve mechanism of the aerosol container is engaged, and the contents are introduced. Introduced into chamber 19.
The subsequent distribution of the contents is the same as in the first embodiment, and when the pressing force on the main body 3 is released, the restoring force of the spring 15 and the restoring force of the valve mechanism of the aerosol container will cause the flow of the contents before the barrier. return to the state. In a third embodiment which is still different, the spring 15 used in the two embodiments described above is not used.

To explain the details with reference to FIG. 3, numeral 38 is a pressure gasket made of a soft elastic material such as soft rubber and having a deformation restoring force weaker than that of a pressure spring used in the valve mechanism of an aerosol container. and its top 39
The valve seat 40 is flat on the inside, and an outlet hole 42 is bored in the side wall 41. 11b is this pressure gasket 38
The lower end of the cylindrical portion 43 is bent outward and the bent piece 44 is inserted into the valve seat 4.
After further raising the end part upward through the arc-shaped part 45, the like part of this raised part 46 is bent and the engagement key 30 of the housing body 27 is opened.
By fixing it to
0 is fixed integrally.

In this structure, the stem 1 is connected to the inlet valve 11.
Insert the stem 1 into the cylindrical part 43 of b and press the main body 3.
The valve seat 40 of the pressing gasket 38 is pushed up and released from the end face of the cylindrical portion 43, and in the next step, the stem 1 is pressed and the contents are squirted from the notch 48 of the stem 1 into the introduction chamber 19. It flows out from the outlet 24. Other operations are similar to those in the first and second embodiments. In a fourth embodiment, which is still different, the introduction chamber 19 as shown in each of the above embodiments is not formed, and the outlet hole 42 of the pressure gasket 38 is arranged substantially perpendicularly to the collision arm 28, as shown in FIG. However, the contents may be made to collide directly with the collision wall 28 without going through the introduction chamber 19 of each of the embodiments described above.

In the present invention, as described above, the contents discharged from the aerosol container collide with the collision wall, so that the propellant and the contents are separated during this collision, and the contents do not have any pressurizing force, resulting in scattering, etc. It can be stored in the storage section without being accompanied by any turbulence and can be used according to the purpose of use.

In addition, once the contents are stored in the storage section, they will not flow backwards and be discharged due to the action of the inlet valve, so in the case of two-component hot shaves, hair dyes, etc., the contents can be stored from one aerosol container. After accommodating the aerosol container in the accommodating section, the contents of the other aerosol container can be transferred from the other aerosol container into the accommodating section in exactly the same manner, thus making it possible to easily mix the two liquids.
