Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for opening a gas vent hole for the purpose of preventing the explosion of a can, which is a problem when disposing or collecting various spray cans.

[0002]

2. Description of the Related Art A large number of spray can punchers, such as a lever type, a hand-push spring type, and a foot spring type, have been proposed so far. However, both of the former two are unstable and require considerable force on their hands, which is dangerous in use. Although the latter receives a force, since the spring seat is provided so that the can does not slip, the stress on the can increases accordingly, and a large force is required to push the pin to project. In addition, all of these are accompanied by the risk of mischief by the child when not in use.
One of the changes is that the pin is relatively projected by using an elastic body (elastic rubber).
Although there is a device of No. 8 and Japanese Utility Model Publication No. 63-156998, they are not only durable in themselves, but also poor in chemical resistance, so that they cannot withstand long-term use. Further, since it has a mouthpiece as a seat, it can bear the resistance due to the stress.

[0003]

DISCLOSURE OF THE INVENTION The present invention has been made in view of the above-mentioned actual circumstances, and does not provide a receiving seat on the pressing member (the common sense that a can slips if there is no receiving seat is broken). The main object of the present invention is to provide a safe-type spray can puncher that can be used efficiently and safely by one-handed work.

[0004]

In order to achieve the above object, the present invention provides a circular pedestal 1 and a piercing pin 2 which is inserted into a center hole 1a of the circular pedestal 1 and is made of a rigid material. A support spring 3 resting on the outer periphery of the perforation pin 2, and a skirt-shaped circular collar 6 at the lower part supported by the support spring 3.
And a pressing member 4 integrally formed with a dome type cap 5 having a pin peephole 5a at the head end in the upper center thereof, and a vertical swing width by the support spring 3 of the pressing member 4 is allowed. A spray can perforator is constituted by a circular skirt-shaped presser cover 7 which presses the skirt-shaped circular collar 6 onto the circular pedestal 1.

Further, in the above structure, a circular skirt-shaped pressing cover is provided on the upper surface of the skirt-shaped circular collar portion 6 of the pressing member 4.
7 is a spray can punching device which is provided with a projection 8 for forming a gap between the spray can and the punch 7.

Further, in each of the above constructions, a hook-shaped projection 9 is formed below the skirt-shaped circular collar portion 6 of the pressing member 4, and the pressing member 4 is rotated in the horizontal direction so that the hook-shaped projection 9 is circular. It is a spray can puncher capable of preventing the downward movement of the pressing member 4 by locking the lock hole 10 provided in the pedestal 1.

Further, in each of the above-mentioned constitutions, a spray can perforator having anti-slip projections 11 provided at intervals in the circumferential direction of the dome type cap 5 of the pressing member 4.

[0008]

In order to use it, when it is placed on a flat surface such as a desk in the state of FIG. 2, the empty can of the spray can is held by the hand of the pressing member 4 as shown in FIG. -Press the pin-shaped hole 5a at the head end of the mu-shaped cap 5 from above. Then support spring 3
Since the pressing member 4 supported on the upper and lower sides is allowed to swing up and down, the pressing member 4 is pushed down and the hole-piercing pin 2 hidden inside is relatively slightly projected from the pin peep hole 5a, and momentarily. Stick into the side of the can (this will cause the can to stick into the pin so it will not slip). Then, by further pushing down from that state, the support spring 3 is further compressed and the pushing member 4 is pushed down, and as a result, the punching pin 2 punches a sufficient gas vent hole. That is, in the present invention, no can seat is provided at the head end of the dome-shaped shade 5, but it is noticed that once the pin is inserted into the can, it will not slip thereafter. In this way, it is possible to perform the punching work intensively and smoothly without receiving any stress due to pressure on the can itself.

The piercing pin 2 is hidden by the pressing member 4 supported by the support spring 3 and does not protrude unless the dome-shaped cap 5 is pressed from directly above, which is dangerous even if it is placed on that side when not in use. (No pin appears unless the dome-shaped cap 5 is pressed from above vertically with a certain amount of force). In particular, a hook-shaped protrusion 9 is formed below the skirt-shaped circular collar portion 6 of the pressing member 4, and the pressing member 4 is rotated in the horizontal direction to cause the hook-shaped protrusion 9 to rotate.
In a mode (that is, with a lock) in which is locked in the lock hole 10 provided in the circular pedestal 1, the danger is completely eliminated.

Further, in a mode in which a projection 8 for forming a gap between the skirt-shaped circular flange portion 6 of the pressing member 4 and the circular skirt-shaped pressing cover 7 is further provided, Even if paint or the like leaking from the spray can flows down the dome-shaped shade 5 and enters between the upper surface of the skirt-shaped circular collar portion 6 and the circular skirt-shaped holding cover 7, the above-mentioned gap is generated. Therefore, it prevents the mutual movement of the two from becoming dull without accumulating or solidifying between them.

[0011]

As described above, the present invention achieves the intended purpose mentioned at the beginning, has a simple structure, is easy to operate, is not dangerous even when not in use, and has an overall shape as if it is a UFO. Since it is a mold, it has a figurative appearance in the room. With the spread of spray cans nowadays, it is a contract that each household will treat them as a regular item.
