Abstract
Fluid dispensing container (1) equipped with a dispensing valve (2) carrying an outlet (3) through which the fluid is dispensed during the actuation of a pushbutton carried by the valve; a conditioning chamber (4) of variable volume defined by a mobile wall (5a) subjected to the internal pressure of the container, communicates, on the one hand, with the dispensing valve (2) and, on the other hand, with the inside (18) of the container through a retarder means made in the form of a passage with high head loss. At the end of emptying of the conditioning chamber (4), the communication between the dispensing valve (2) and the inside (18) of the container is interrupted.
