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.

A device for dispensing a pressurized material, includes a body defining a pressurizing chamber containing a gas generator, a tank for containing the material that is to be delivered, and a piston, the gas generator being configured so that when it is triggered it causes the device to pass from a material-storage, first configuration to an end-of-material-dispensing, second configuration. In the first configuration, the piston is held in position in the body by an elastically deformable holder element extending axially, that is secured to the first end wall. The piston is held stationary relative to the first end wall by a holding force from the holder element. When the gas generator is triggered, it exerts a force on the piston that opposes the holding force to enable the piston to move by releasing the first end wall and thus causing the device to pass from the first to second configuration.
