BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a degassing cap for an aerosol container, and more particularly to a cover cap for discharging a residual gas or the like safely and without contamination when the aerosol container is discarded. .

[0002]

2. Description of the Related Art Conventionally, aerosol containers for cosmetics, insecticides, paints, etc. are filled with contents and gas as a propellant, and when discarded, the remaining contents and gas are discharged. Therefore, even if the contents are used up, there is a danger that the residual gas may cause erroneous heating, or may explode when heated upon disposal.

[0003] Therefore, since it is necessary for the user to ensure that the contents and gas remaining in the aerosol container are discharged, the cover cap of the aerosol container is provided with a function of degassing so that it can be easily discharged. Various types have been proposed, which are usually used as cover caps, and are used to discharge the remaining contents and gas continuously by using the degassing function at the time of disposal, etc. is there.

[0004] For example, FIG.
In the cap 1 for an aerosol container described in the publication, a cylindrical stem pressing member 4 with a bottom is formed integrally with a top plate portion 2 of the cap 1 fitted into the mountain cup B of the aerosol container A via a connecting piece 3. The stem pressing member 4 can be locked to the central upright portion D of the aerosol container A to which the stem C is mounted. In this locked state, the stem C can be pressed down by the top plate portion 2 and A communication hole 5 with the outside is formed in the plate portion 2.

Therefore, when the aerosol container A is discarded, the cap 1 attached to the aerosol container A
The stem pressing member 4 is pushed in and separated from the connecting piece 3, the stem pressing member 4 is locked to the central rising portion D of the aerosol container A, and is continuously ejected to discharge gas from the communication hole 5 of the top plate portion 2 to the outside. And so on.

For example, Japanese Patent Application Laid-Open No. 11-70 shown in FIG.
In the vent cap 6 of the aerosol container described in Japanese Patent No. 986, 2 is formed on the side wall portion 7 of the cap 6 fitted into the top dome E covering the upper part of the aerosol container A.
A reversing locking plate 10 is formed integrally with the two concave streaks 8 as axes, and the upper and lower portions are cut by a cutting groove 9 and are inverted. The stem is formed with the reversing locking plate 10 inverted so as to protrude inward. The stem can be pushed down via the discharge member F mounted on the stem.

Therefore, when the aerosol container A is to be discarded, the aerosol container A is mounted on the top dome E of the aerosol container A in a state where the reversing locking plate 10 of the cap 6 is inverted so as to protrude inward. Then, the stem is pushed in and continuously ejected to discharge gas or the like to the outside through the gap of the reversing locking plate 10.

Further, for example, Japanese Patent Application Laid-Open No. 2000-2000 shown in FIG.
Aerosol cap 11 described in 191062
In this case, two folding plates 14 that are cut in the top plate 12 of the cap 11 and can be bent inward in the vertical direction at the thin portions 13 are provided, and the folded plate 14 in a folded state is provided.
The nozzle F can be brought into a state where it is pushed in by the tip of.

Therefore, when the aerosol container A is discarded, the folding plate 14 is vertically bent inside the top plate 12 of the cap 11 and the cap 11 is attached to the aerosol container A, so that the nozzle F is pushed in and the continuous injection is performed. Then, gas or the like is discharged to the outside from the hole of the top plate 12 formed by the bent plate 14.

[0010]

However, in the first aerosol container cap 1, since the stem pressing member 4 is formed integrally via the connecting piece 3, a gap is formed in the top plate portion 2 of the cap 1. There is a problem that the function as the original cap is impaired, and it is necessary to push the stem pressing member 4 from above at the time of degassing. However, there are also problems such as danger of blowing out and contamination due to scattering of residual contents.

Further, in the degassing cap 6 of the second aerosol container, the reverse locking plate 1 on the side wall portion 7 of the cap 6 is provided.
Since the gas is released by pushing 0 inward, the gas or the like discharged at the time of degassing does not blow upward, but scatters outside the cap 6 depending on the amount of remaining contents and gas. There is such a problem.

Further, a third aerosol cap 11
In this case, it is necessary to push the bending plate 14 into a vertical state as a preparation before degassing, but at this time, by pressing the bending plate 14, a finger enters a hole portion formed by the cut and the thin portion 13, and a finger enters the edge. In addition to the problem that there is a risk of collision, there is also a problem that the discharged gas is blown upward and that dust is generated by scattering.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a cap for venting an aerosol container according to an embodiment of the present invention. 1 to 3 show an embodiment of an aerosol container degassing cap of the present invention.
1 is a longitudinal sectional view and a bottom view, and FIG.
FIG. 3 is a longitudinal sectional view showing only the cap in a degassed state and a longitudinal sectional view shown together with the aerosol container.

The degassing cap 20 of the aerosol container is a cylindrical plastic cap cap body 21 with a bottom which is engaged with the outer periphery of a top dome E covering the upper part of the cylindrical can body of the aerosol container A. With
Normally, the bottom portion of the cover cap body 21 is used as a top surface, and the opening is downward so as to cover the top dome E of the aerosol container A. A plurality of locking portions 22 are integrally formed at equal circumferential intervals.

The cover cap body 21 of the degassing cap 20 has a plurality of valve opening plates 24 projecting downward from the lower surface of the top plate 23, and in this embodiment, two valve opening plates 24 are provided with cover caps. The valve opening plate 24 is integrally formed via a hinge portion 25 so that the valve opening plate 24 can be tilted toward the center of the main body 21.
So that it does not come into contact with the top dome E, the stem C that constitutes the valve, and the button F with the nozzle attached to the stem C, etc. They are formed so as to face each other with the central axis interposed therebetween at a slightly wide interval.

At the lower ends of these two valve opening plates 24, there is provided an intersecting connecting portion 26 which intersects each other in an approximately isosceles triangular shape and connects each end so as to slightly project.
Is provided, the lower side of the intersection 27 is a valve contact surface for opening the valve, and in this embodiment, the stem C
Is pressed directly to make the injection state, so that the intersection 27 becomes a stem contact surface.

Therefore, the intersection 2 of the valve opening plate 24
The size of the position 7 is adjusted so that when the gas release cap 20 is fitted and mounted on the top dome E of the aerosol container A, the stem C can be pushed down to allow continuous ejection.

The cross connection 26 between the two valve opening plates 24
The insertion hole 28 is provided at the lower end of one valve opening plate 24.
Is formed at the lower end of the other valve opening plate 24 to form a projecting piece 29 that enters the insertion hole 28.

The intersection 2 of the two valve opening plates 24
In order to enlarge the contact area with the stem C so as to increase the contact area with the stem C, the distal end side of the valve opening plate 24 is bent toward the center without intersecting with the intersection portion 27, and corresponds to the width of the insertion hole 28 in the valve opening plate 24 in which the insertion hole 28 is formed. Bending part 30 only at the part to be bent
Is formed, and the valve opening plate 24 on which the projection 29 is formed
In this example, a bent portion 30 is formed over the entire width of the projecting piece 29, and when the two cross each other, the crossing portion 27 spreads outward by the amount of the bent portion 30.

Further, in this gas release cap 20,
The aerosol container A of the cover cap main body 21 in the state of use as the normal cover cap shown in FIGS.
The bottom wall of the inner space of the cap when fitted to the top dome E, and the uppermost space of the inner space of the cover cap body 21 in the inverted state shown in FIG. A penetrating gas vent hole 31 is formed as a gas vent portion. Here, four small-diameter gas vent holes 31 are formed at equal circumferential intervals. The gas venting section is not limited to the gas venting hole 31 and may be formed as a gas venting groove by forming a groove between the gas barrier cap body 21 and the outer periphery of the top dome E of the aerosol container A. Alternatively, degassing can be performed at a higher position in the space inside the cap.

In the degassing cap 20 of the aerosol container constructed as described above, the cover cap body 21 is provided around the top dome E of the aerosol container A in the normal state.
Are fitted and fitted and locked by the locking portion 22 to function as a cover cap. This degassing cap 2
0 is used as a cover cap, since the interval between the valve opening plates 24 is set so as not to come into contact with each part of the aerosol container A, it can be used as a cover cap without any trouble, and the gas vent hole 31 has a small diameter cap. Since it is the lowest side of the inner space, no large gap is formed, and the function as the cap is not impaired.

On the other hand, when the aerosol container A is to be discarded, first, as shown in FIG. 3A, the degassing cap 20 is removed from the aerosol container A and protruded into the cover cap body 21. The two valve opening plates 24 are tilted toward the center so that the
Of the cover cap body 21 in the cross connection state, and the stem C is pushed down when the cover cap body 21 is mounted on the aerosol container A. It can be so.

Thereafter, as shown in FIG. 3 (b), the gas vent cap 20 is fitted in an inverted state with the top plate 23 facing down, the opening facing upward, and the stem C of the aerosol container A facing downward. Attach together.

When the outer periphery of the top dome E of the aerosol container A is fitted and mounted on the degassing cap 20, the stem C is automatically pushed down at the intersection 27 of the valve opening plate 24 to be in a continuous injection state. The contents and gas remaining in the space of the cover cap main body 21 are discharged, and when there is a large amount of residual gas, the contents and gas are discharged to the outside through the upper gas vent hole 31.

Therefore, only by fitting the outer circumference of the top dome E of the aerosol container A to the inverted gas release cap 20 by fitting, the residual gas can be automatically released. The pulling operation is extremely simple.

Further, since the gas remaining in the aerosol container A is injected into the cover cap body 21 and then discharged outside through the small-diameter gas vent hole 31, the gas is safely discharged from the aerosol container A. can do.

Further, even if there is a content remaining in the aerosol container A together with the gas, the cover cap body 21
It can be stored inside the container, can be safely discharged from the aerosol container A, and the contents do not scatter with the gas and do not pollute the surroundings.

Further, in this degassing cap 20, a hinge 25 is attached to the top plate 23 of the cover cap body 21.
Since the valve opening plate 24 is integrally formed through
It can be folded down and crossed with a slight force to be crossed and connected at the connection crossing portion 26, and there is no danger of contact with the notch as in the case where the bent plate of the conventional top plate portion is pushed in. Moreover, the length of the bent plate is not enough due to the diameter of the top plate portion or the distance to the tip of the stem, and there is no design restriction that the stem cannot be pushed.

Further, by folding the two valve opening plates 24, 24 inward to form an isosceles triangle, the force required to push the stem C is evenly distributed to ensure sufficient strength. Can be.

Further, since the degassing cap 20 can be integrally formed as a one-piece structure made of synthetic resin, it is easy to manufacture and inexpensive.

In addition, in the state where the gas is vented, since the bubble release plates 24 and 24 remain in a connected state, the gas vent is completed by removing the cover cap body 21 from the aerosol container A. You can easily know whether or not.

In the above embodiment, the case where the stem is directly pushed down by the valve opening plate has been described as an example. However, in the case where the stem is pushed down via buttons of various shapes attached to the stem. Any type can be used as long as the valve of the aerosol container can be opened to make a continuous injection state.

Further, the bubble release plate is not limited to the case where it is composed of two opposed plates, but may be composed of three or more plates. Instead, another connection structure such as a fitting type may be used.

Further, as is clear from the description of the above-described embodiment, degassing in the present invention includes not only removing the residual gas but also removing the residual gas and the residual contents.
