The pressurized cylinder C has an upper wall 12a made of a thin metal material similar to that of the aerosol container B, and the inside thereof is filled with a pressurized medium such as carbon dioxide gas.

The pressurized cylinder C is housed upright in a case 13 whose top surface is open, and a female thread 13a formed on the inner periphery of the upper end of the case 13 is screwed into the male thread 1c on the lower outer periphery of the casing 1. , the upper wall 12a of the pressurized cylinder C is configured to be pressed toward the cap 3.

In the figure, 14 is a packing interposed between the upper end of the stopper 6 and the bottom wall of the aerosol container B, and 15 is a packing interposed between the lower end of the casing and the upper end of the pressurized cylinder C.

Next, a second embodiment of the present invention is shown in FIGS. 2 and 3. Hereinafter, parts having the same configuration as in the first embodiment will be given the same reference numerals as in the first embodiment, and the explanation thereof will be omitted.

The piston 20 to be fitted into the cylinder chamber 1a of the casing 1 is formed into a flat plate shape, and
A second flow path 21 is provided on the side wall of the casing 1 facing the bottom of the casing 1, and a piercing tool 9 is attached to the outer side of the flow path 21. At the location where the drilling tool 9 is located, an annular arm 22 is provided which projects outwardly from the casing 1 as shown in FIG. A fastener E that can move in and out of the direction of the piercing tool 9 is attached. This fastener E consists of a tightening bolt 24 having an operating handle 23, and is adapted to press the aerosol container B fitted into the arm 22 toward the piercing tool 9. In the figure, 25 is a pressing piece provided at the pressing side end of the bolt 24.

On the other hand, in the upper part of the casing 1, a cylinder chamber 1a is provided.

Next, how to use the pressurizing tool for an aerosol container of the present invention will be explained. In FIG. 1, after placing the aerosol container B above the connector A, if the female thread 10b of the recess 10a is firmly screwed into the screw 6d of the stopper 6, the piercing tool 9 is inserted into the upper part of the recess 10a. The tip is strongly pressed and penetrated through the upper part.

Note that the peripheral wall 10 of the aerosol container B is made of a thin metal or plastic material, so it can be easily broken through.

Next, after housing the pressure cylinder C in the case 13, if the upper female thread 13a of the case 13 is firmly screwed into the male thread 1c provided on the lower outer periphery of the casing 1,
The thin upper wall 12a of the pressurized cylinder C
The tip of the cap 3 is strongly pressed, and the upper wall 12a
It is penetrated through. As a result, the first flow path (not shown) formed in the base 3 and therefore the bottom wall 2 of the casing 1 communicates with the inside of the pressurized cylinder C. At the same time, the gasket 15 interposed between the bottom surface of the casing 1 and the top surface of the pressure cylinder C is clamped by the engagement force between the female thread 13a and the male thread 1c, and the contact area between the bottom surface of the casing 1 and the top surface of the pressure cylinder C is pressed. Seal it tightly. This results in the piercing tool 9 and therefore the second part of the plug 6.
The flow path 6a and the inside of the aerosol container B communicate with each other. In addition, the upper surface of the recess 10a of the aerosol container B and the stopper 6
Since the packing 14 is interposed between the upper surface and the upper surface, the abutting portion is sealed by the engagement force between the female thread 10b and the screw 6d.

Due to the communication between the first flow path and the inside of the pressurized cylinder C, the pressurized medium inside the pressurized cylinder C flows through the first flow path, the intermediate flow path 5c formed in the piston 5, and the second flow path 6a. and flows into the aerosol container B.

In this case, a pressure regulating valve 4 that is interlocked with the piston 5 and closes the first flow path during upward movement is installed in the bottom wall 2, so that the pressure increase in the aerosol container B of the pressurized cylinder C is prevented. Maintained at set pressure.

Next, when the on-off valve 11 is pressed with the aerosol container B and the pressurized cylinder connected, the on-off valve 1
1 opens, and the liquid or powder contained in the aerosol container B is ejected from the bottom of the aerosol container B through the outflow pipe 11a and from the spout 11b of the on-off valve 11 to the outside. .

In addition, even if the pressurized cylinder is emptied with the filling remaining in the aerosol container,
The filling material begins to flow out to the second flow path 6a, but this is stopped by the check valve 6b.

Next, in the second embodiment shown in FIG. 2, when the aerosol container B is inserted into the annular arm 22 and the fastener E is rotated in the fastening direction, one side wall of the aerosol container B is pierced. It is pressed in nine directions and the one side wall is pierced by the tip of the piercing tool 9. Next, if the pressurized cylinder C is connected to the connector A by the same operation as in FIG. 1 described above, the second flow path 21
and aerosol container B communicate with each other. As a result, the pressure inside the aerosol container B is increased by the pressurized cylinder C by the same action as described above.

Accordingly, when the on-off valve 11 is operated in the opening direction by the arm 27, the contents in the aerosol container B are ejected from the ejection port 11b toward the outside through the outflow pipe 11a.

<Effects of the Invention> The present invention has such a pressurizer that the number of fastening points and sealing points is reduced, so fastening and leakage prevention are simplified, and the present invention has a practical effect that it is extremely easy to handle. In addition, since the pressure is always maintained at the set value by the pressure regulating valve, the spray condition remains unchanged from beginning to end, and the pressure resistance of the container is low, making it easy to prevent leakage.
