Abstract
An assembly for packaging and pressurized dispensing of a product, particularly a cosmetic, including a first container which is surmounted by a first valve capable of moving from a closed position to an open position for dispensing the product, and which defines two compartments which are separated in a leaktight manner by a movable piston. The first compartment contains the product and the second compartment receives a propellent gas capable of pressurizing the product via the movable piston. When the valve is in a closed position, the second compartment is substantially at atmospheric pressure.
