[Conventional technology]

Conventionally, when applying two-component paints such as urethane resin paint, urethane foam, or epoxy resin to the target surface, and when using hair dye with an aerosol device, polyols, isocyanates, and epoxy resins are used. Two types of liquid contents, such as a curing agent, an oxidizing agent, and a reducing agent, which must be stored separately before use, are placed in two aerosol cans, and the liquid contents are injected from each aerosol can to initiate a reaction. Alternatively, they are used after being mixed.

These aerosol cans require two cans to be injected at the same time, and conventional operating means include those shown in Japanese Utility Model Publication No. 49-17442 or Japanese Utility Model Publication No. 49-16568.

For the former, two aerosol cans are placed in series in a cylindrical casing with their valves facing each other, and one aerosol can is pushed through a hole in the end of the casing with a finger, etc. The injection buttons of the aerosol cans are opened at the same time. In the latter case, two aerosol cans are placed in parallel in a large-diameter casing, each valve is connected with a branch pipe, a push button is attached to each branch pipe, and the two push buttons can be operated simultaneously. By doing so, the injection operation is performed.

[Problem that the invention attempts to solve]
