Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for extracting a filling material from various spray cans (including a cassette gas cylinder).

[0002]

2. Description of the Related Art When disposing of spray cans and cassette gas cylinders for hairdressing and the like after use, discarding cans is done at home and the like under the guidance of the cleaning bureau of each local government.

[0003] In view of the above, at present, a can is sandwiched by a tool such as a large-sized yatco, and a hole is directly formed in the can by a sharp projection formed inside the can, or a hole is directly formed by a hammer having a sharp point. Instruments that can open are available on the market.

[0004] However, spray cans of paint or the like are rarely used because the paint is ejected.

[0005] However, as a result of discussions between the Tokyo Metropolitan Government Cleaning Bureau and the Tokyo Fire Department on June 2, 1999, when drilling holes using the above-mentioned appliances, explosion accidents did not occur. Discard it without making a hole. "

[0006]

The features of the above-mentioned prior art are listed below.

[0007] 1. When making a hole in a can, a gas stove or the like ignites and an explosion has occurred.

[0008] 2. The cans were discarded without making a hole, and the collected cleaning car fired.

3. Most spray cans for hairdressing and the like use flammable liquefied petroleum gas (mainly LP gas) from CFC gas due to environmental problems.

[0010] 4. Most paint spray cans use flammable gas (mainly LP gas) from chlorofluorocarbon gas due to environmental problems and also contain highly flammable solution (thinner).

5. If the remaining amount of the cassette gas cylinder becomes small, the thermal power will decrease. Therefore, it is common to replace the cassette gas cylinder with a new one without using up.

6. Cassette gas cylinders are frequently used in restaurants as well as in ordinary households, and the replacement time is the same as in the previous section.

7. Hairdressing users tend to prepare a wide variety of items for many young people, and they rarely use up their hair and are often bored with it.

8. In the case of paints, they are rarely used up and are often discarded as they are.

9. In the case of hair styling materials and paints, if gas is vented for disposal, oil components and paint pigments scatter and deteriorate the environment.

10. Degassing without making a hole in the can requires a considerable amount of time and effort.

11. For this reason, even if consumers are demanded to “use up”, it is impossible to do so, and it is difficult to predict that the number of accidents and fires will decrease.

[0018]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS First, a spray can to be treated according to the present invention will be described with reference to FIGS. FIG. 5 shows the characteristics of the nozzles of various spray cans. (A) and (b) are paint spray cans, (c) is an insecticide spray can, (d) is a cosmetic spray can, and (e) is a spray can. It is a cassette gas cylinder. In these figures, 100
Is a can main body, 101 is a spout provided in the can main body 100, and 102 is a nozzle attached by press-fitting the spout 101.

As a common point between the cassette gas cylinder of FIG. 5E and the spray can 101 of the spray can of FIGS. 5A to 5D, various nozzles 102 are attached to the spray can. But it can be easily removed. When the nozzle 102 is removed, the appearance of the jet port is exactly the same as that of the cassette gas cylinder. This is indicated by reference numeral 101 in FIG. Therefore, in the present invention, a cassette gas cylinder is included in the spray can.

As shown in FIG. 6, the bottom of the can body 100 has a concave bottom surface 103 which is concave toward the inside so as to withstand the internal gas pressure.

As shown in FIG. 7, a single tube 104 extends from the spout 101 toward the bottom, and extends several millimeters from the bottom. However, there is also a thing without this tube 104.

When the nozzle 102 is pressed down while the nozzle 102 is facing down, the contents and gas can be simultaneously extracted. This is shown in FIG. If the hole of the nozzle 102 is facing sideways,
By pushing the nozzle with the nozzle 102 up, the contents and gas can be simultaneously extracted. This is shown in FIG.

When the nozzle 102 has the hole facing upward, only the gas can be extracted by pushing the nozzle 102 with the nozzle 102 facing upward. This is shown in FIG. If the hole of the nozzle 102 is oriented sideways, only the gas can be extracted by pressing the nozzle 102 with the nozzle 102 down. This is shown in FIG.

The amount of gas and contents ejected depends on the opening amount of a valve (not shown) in the can body 100. That is, a large amount is ejected when the nozzle 102 or the ejection port 101 is strongly pressed down, and a small amount is ejected when the nozzle 102 or the ejection port 101 is weakly pressed. .

As described above, there are a wide variety of spray cans.
00 is provided with a spout 101.
Has the common feature that when pressure is applied to the contents, the contents are ejected. The present invention has been made using the above findings, and examples of the present invention will be described below.
