易いようにしている。Some aerosol cans are filled with carbon dioxide gas or the like in addition to the liquid contents in order to increase the internal pressure. The carbon dioxide gas pressure filling is performed by filling the aerosol cans with the contents. After that, it is performed by a valve device caulked and connected to an aerosol can. At the time of pressure filling of carbon dioxide gas from the valve device, the pressure rises by dissolving carbon dioxide gas in the liquid that is the content in order to avoid the internal pressure of the aerosol can rising rapidly above the specified pressure due to the gas filling. It is necessary to suppress it.
On the other hand, since carbon dioxide gas is ejected from the tip port of the dip tube into the contents, the carbon dioxide gas is dissolved in the contents to some extent, but often not enough. For this reason, conventionally, the aerosol can is shaken from the outside to stir the contents, so that the carbon dioxide gas is easily dissolved in the contents.
