ABSTRACT:
A pressurized container (1) containing a fluid product to be dispensed and a propellant gas. The container includes a valve for dispensing the product that includes a heat-sensitive safety device (D) for opening the valve and causing the inside of the container to permanently communicate with the atmosphere when the temperature inside the container exceeds a predetermined threshold temperature. The safety device (D) includes a stopper (106) made of a material that is thermodeformable at the threshold temperature. The stopper closes an orifice (105) in an actuating stem of the valve when the threshold temperature is not exceeded, and opens the orifice when the threshold temperature is exceeded.
