Device for filling an aerosol receptacle with gas through a pump crimped on the receptacle

摘要

The device (102) is intended to inject a gas under pressure into an aerosol receptacle (100) through a pump or spray head crimped onto said receptacle. The purpose of the gas is to prevent air from penetrating into the aerosol receptacle as the liquid contained therein is sprayed out. The device is actuated by the pressure of the filling gas and it includes a damping system for ensuring uniform operation.
