Abstract
A device for dispensing a pressurized material, includes a body defining a pressurizing chamber containing a gas generator, and a tank containing the material to be dispensed, the tank being defined by an end wall having an outlet orifice. The device includes a piston, to move inside the body, separating the pressurizing chamber from the tank, the gas generator to trigger the dispensing of the material to the outside of the body through the outlet orifice by causing the piston to pass from a material-storage, first position to an end-of-material-dispensing, second position in which the piston faces the end wall. The piston, when in the first position, presents a housing that is closed by a fragile portion beside the pressurizing chamber and that is open beside the tank, the housing containing a striker element that is held in the housing and that defines a channel opening out into the tank.
