Description

[Detailed Description of the Invention] This invention relates to a residual gas venting device that extracts the gas filled in an aerosol container when the container is disposed of, thereby preventing accidents caused by residual gas.

As is well known, aerosol containers eject the contents using gas pressure.When disposing of an aerosol container, there is no problem as long as the gas is completely released, but gas remains inside the container. Because they were sometimes disposed of in such a state, the residual gas could cause explosions and other accidents. Particularly in the case of double-walled aerosol containers that separate the contents and gas, the gas remains inside the container without being released, making explosions more likely.

Therefore, this invention has devised a gas venting device that can make a gas vent hole in the bottom wall of the aerosol container when it is disposed of, thereby making it possible to prevent accidents caused by residual gas.

Next, the structure of the gas venting device of the present invention will be explained with reference to drawings of embodiments.A is an aerosol container body that fills the container with gas, and the bottom wall a of the container body A has a dome shape toward the top; A recess B is preferably provided in a part of the outer surface of the center part of the bottom wall a, and the recess B encloses the thin wall part b. is the above container body A
A pin 6 for making a gas vent hole is attached to the hakama 1 that fits on the bottom of the hakama.
This gas venting device is provided with a holding holder 5 and a protective wall 7 for preventing malfunction of the holder 5. The pin holder 5 of the gas venting device is connected to the center of the hakama sole 10 so that it can be bent or cut. An inner circumferential wall 2 that is vertically disposed through the band 4 and circumscribes the bottom wall a of the container body A is placed above the hakama sole 10 on the outer periphery of the pin holder 5.
An outer peripheral wall 3 is provided on the outer periphery of the hakama sole 10 to fit on the lower outer periphery of the container body A, and a protective wall 7 is provided on the lower part of the hakama sole 10 on the outer periphery of the pin holder 5 and extends downwardly from the pin holder 5. The pin holder 5 locks the pin 6 in which the needle 16 reaches the upper part of the inner circumferential wall 2, and by bending or cutting the connecting band 4, the pin holder 5 rises into the inner circumferential wall 2 and can be inserted. A gas vent hole c is formed in the bottom wall a of the container body A by the needle 16 of the pin 6 that is engaged with the pin holder 5, and the protective wall 7 for preventing malfunction of the pin holder 5
are provided continuously below the outer circumferential wall 3 of the hakama to serve as legs, and desirably have a notch 8 formed in a part thereof, or a pin holder 5 is provided at the bottom of the hakama sole 10.
An inner circumference protection wall 17 with a large circumference is provided, and an outer circumference protection wall 27 which also serves as a leg is provided at the lower part of the hakama outer circumference wall 3.
7 and the inner circumferential wall 2 are formed by dividing into an annular or arc shape, and the connecting band 4 is formed continuously or divided into several pieces by providing through holes 14.

Since the residual gas removal device of this proposal has the above structure,
Hakama 1 with a pin holder 5 and its protective wall 7 provided in advance
The container is made of synthetic resin, the pin 6 is made of a harder material than the aerosol container body A, and the needle 16 of the pin 6 is placed in the center of the hakama sole 10 from the top of the hakama 1 with the needle 16 facing upward. The pin 6 is pressed into the pin holder 5 and is fixed irremovably by the protruding claw 15 provided on the holder 5. Insert the container body A from above toward the hakama sole 10, with the bottom wall a of the container body A facing down, until the container bottom wall a comes into contact with the inner peripheral wall 2 of the hakama 1. The lower part of the container main body A is fitted into the outer peripheral wall 3 of the container main body A, and the hakama 1 is attached to the lower part of the container main body A by the outer peripheral wall 3 which is in pressure contact with the outer peripheral lower part of the container main body A. A pin holder 5 hanging down from the hakama sole 10 of the hakama 1 attached to the container body A is protected from malfunction by a protection wall 7 hanging down below the pin holder 5.

When discarding the aerosol container equipped with the gas venting device of the present invention as described above, the pin holder 5 is installed vertically on the hakama sole 10 of the hakama 1 fitted to the lower part of the container body A.
Forcibly press from the bottom towards the top,
At that time, if the pin holder 5 is pressed while avoiding the protective wall 7, the pin holder 5 is integrally molded with the hakama sole 10 via the connecting band 4, which can be bent or cut. Using the needle 16 of the pin 6 which is deformed or cut and inserted upward into the inner circumferential wall 2 and fitted and fixed to the holder 5, the thin wall part b of the container bottom wall a is used.
A gas vent hole c is provided in the container to enable the gas filled in the container to escape from the gas vent hole c, thereby preventing an explosion accident due to residual gas.

In addition, the specific implementation of the invention is not limited to the above embodiment, but an insertion hole 25 parallel to the hakama sole 10 may be provided in the upper part of the pin holder 5 hanging from the hakama sole 10, Even if the locking plate 9 is inserted from the outside of the hakama 1 into the insertion hole 25, malfunction of the pin holder 5 can be prevented. The holder 5 and the connecting band 4 and protective wall 7 of the holder 5
The shape, structure, etc. can be changed as appropriate as long as it does not go against the gist of this invention.

Therefore, the residual gas venting device of the present invention has a pin holder that can be raised toward the bottom wall of the container attached to the lower part of the container body, and a hakama with a protective wall for the pin holder, so that the aerosol container can be discarded. At this time, a gas vent hole can be created in the bottom wall of the container by simply pressing the holder toward the bottom wall of the container, avoiding the protective wall. By completely removing the remaining gas, explosions caused by residual gas can be prevented. Furthermore, since the pin holder is prevented from malfunctioning by the protective wall, it will not malfunction not only during transportation but also during use of the aerosol. In addition, since the pin holder and its protective wall are integrally molded with the hakama and lock the pin in the pin holder, it is easy to manufacture and assemble and can be provided at low cost. The residual gas venting device of the present invention is particularly useful as a residual gas venting device for double-structured aerosol containers in which residual gas remains in the container, and the residual gas venting device of the present invention has a significant practical effect in preventing accidents due to the disposal of aerosol containers.
