できる。[Effects of the Invention] As described above, according to the present invention, one end of the inner lid top plate is connected to the upper end of the inner lid to be fitted on the aerosol can so that the inner lid top plate is swingably connected. Then, a nozzle is integrally erected at the central portion of the inner lid top plate and fitted into the ejection pipe protruding to the upper end of the aerosol can, and the top plate is pressed down on the swinging end surface of the inner lid top plate. The top plate retainer is provided with a protrusion that engages with the upper end edge of the outer peripheral wall of the top retainer that swings largely downward, on the inner peripheral wall of the inner lid that opposes the top retainer. The gas filled in the aerosol can is completely discharged by simply swinging the upper part of the top plate and engaging the top edge of the outer peripheral wall of the top plate with the step of the engaging protrusion protruding from the peripheral wall of the inner lid. It can be ejected until it is completely discharged of the contents and residual gas in the aerosol canister. Therefore,
When you dispose of the aerosol device after using it or after discontinuing its use in the middle of the process, the gas filled in the aerosol can can be completely discharged through the nozzle attached to the aerosol can, making it extremely easy and safe. It is possible to discharge the gas filled in the aerosol can.
Further, the structure is extremely simple, and it can be manufactured at a low cost.
