BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an aerosol can for an aerosol product, which is equipped with a degassing tool for removing residual gas.

[0002]

2. Description of the Related Art Aerosol products are prepared by mixing active ingredients such as chemicals, detergents, paints, etc. with a propellant, filling an aerosol can (pressure resistant container) and ejecting them in a mist form from a nozzle. The nozzle 2 is provided at one end of the aerosol can 1 as shown in FIG. LNG (liquefied natural gas), LPG (liquefied petroleum gas), DME (dimethyl ether), etc. are used as a propellant, and iron and aluminum cans are used as aerosol cans.

[0003]

[Problems to be Solved by the Invention] The propellant of an aerosol product is sealed at a high pressure, and the propellant remains even when the active ingredient in the can is used up and is used (the active ingredient is lost). Therefore, if a used aerosol can is carelessly dumped in any place, it will explode if the place becomes hot, and it will harm other people, and if the used aerosol can is discarded as it is, it will be dusty. When the aerosol can is compressed and crushed during processing at the processing facility, a high temperature is generated and it may burst, which may be dangerous to the processing worker.

[0004] Therefore, although efforts are being made by traders, local governments, etc. to ensure that ordinary consumers must thoroughly degas, discard, and dispose of used aerosol cans. It is often discarded and discarded without thorough degassing.

On the other hand, hammer-shaped, pliers-shaped and can opener-shaped degassing devices have been conventionally sold. However, even if such another device is purchased, it is not used because it is stored in a different place from the aerosol can and it is not actually used because the precautions for use are not clear. Has not disappeared. This is because the degasser has not been attached to the aerosol can since the manufacturing stage, and the majority of people have little awareness of the disposal problem. Further, when these devices are attached to the outside of the aerosol can, the appearance of the aerosol can is deteriorated, which hinders storage and is inconvenient to cover with a plastic film.

According to the present invention, at the stage of manufacturing an aerosol can and an aerosol product, the degassing tool is fixedly attached to the can without deteriorating the appearance of the aerosol can.
The purpose of the present invention is to solve the above-mentioned problems by allowing the user to easily perform the degassing work, and also to draw the user's attention.

[0007]

In order to achieve the above object, an aerosol can with a degassing tool according to the present invention has a mounting body (3) in which a metal degassing tool (P) is incorporated so as to be erected. Is fitted to the bottom of the aerosol can (1), and the mounting body (3) is provided with a peripheral edge (4) fitted to the bottom of the aerosol can and a tongue connected to the peripheral edge. A curved and deformable bottom plate part (5) forming a piece-shaped bottom plate and a holding part (6) standing upright on the bottom plate part and facing the aerosol can are integrally formed into a substantially cup shape. The degassing tool (P) is composed of a rotating shaft (8) rotatably held by the holding portion and a degassing needle (7) which is continuously provided orthogonally to the center of the rotating shaft. When the bottom plate portion (5) is curved and is deformed and the degassing tool (P) is operated to stand up, Probe tip portion of the venting needle (7a) is configured to be higher than the peripheral portion (4).

[0008]

In the aerosol can according to the present invention, after use, the bottom plate portion is first bent and deformed, and the degassing tool is erected. When the degassing tool is erected in this way, the needle tip of the degassing needle is configured to be higher than the peripheral edge of the mounting body, so hold the aerosol can on the surface of a table or desk. You can finish the degassing work inside the can by opening it at the bottom by simply pressing it firmly against.

As described above, in the present invention, the degassing tool is integrated with the aerosol, and degassing can be performed by a simple standing operation. Further, it is possible to easily perform the degassing operation without using another member such as a hammer. Furthermore, the mounting body incorporating the gas vent is
When it is attached to the bottom of the aerosol, no externally projected portion is formed, so that the external appearance of the aerosol can is not impaired, and the cautions and instructions can be easily displayed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. As shown in FIG. 1, an aerosol can with a degassing tool according to an embodiment has a mounting body 3 on the bottom of the aerosol can 1.
Is attached. The mounting body 3 is preferably made of plastic, but a metal degassing tool P, which will be described later, is incorporated in the mounting body 3 so as to be capable of standing up. As shown in the plan view of FIG. 3 and the AA cross-sectional view of FIG. 2, the mounting body 3 has a peripheral edge portion 4 fitted to the bottom portion of the aerosol can 1, and a tongue-shaped member continuously provided to the peripheral edge portion 4. The bottom plate portion 5 that forms a bottom plate and can be curved, and the holding portion 6 that is erected on the bottom plate portion 5 and faces the aerosol can 1 are integrally formed. Further, the holding portion 6 has a "dogleg shape" with an open tip.
The notch is provided and both ends 6 of this notch are
Each of a and 6b has a shape as shown in FIG. As shown in FIG. 6, the degassing tool P includes a rotating shaft 8 that is rotatably held by the holding unit 6 and a degassing needle 7 that is continuously provided orthogonal to the rotating shaft 8. It has a substantially T-shape as a whole. Here, the rotating shaft 8 preferably has a square cross section with rounded corners, but may have a circular cross section as shown in FIGS. 2 and 4. Since the degassing needle 7 has a sufficient length, when the degassing tool P is erected, the degassing needle 7 is
The needle tip portion 7a of the above becomes higher than the peripheral portion 4 of the mounting body 3 (see FIG. 4). As described above, the degassing tool P can be operated upright, but normally, it is tilted and stable as shown in FIG. Then, with the degassing tool P lying down, the mounting body 3 is fitted onto the bottom of the aerosol can body 1, and the outside thereof is covered with the shrinkable plastic film. As shown in the figure, since the aerosol can has no protruding portion, it can be easily covered with a film, but it may be adhered using an adhesive.

When the aerosol can is used, the bottom plate portion 5 of the mounting body 3 is pulled out downward as shown by the dotted line in FIG. 2, and the gas venting needle 7 is set upright as shown by the dotted line in FIG.
