An assembly is provided for packaging and dispensing a pressurized product, in which the assembly includes a container containing the product and a dispensing element fitted to the container and provided with an activating member. The activating member can be moved along a longitudinal axis X of the dispensing element, and a dispensing head is mounted on the container by a collar. The dispensing head includes an actuating member that can be moved relative to the collar, and the coupling between the collar and the actuating member is such that rotating the actuating member relative to the collar causes displacement of the activating member along the axis X to dispense the product through at least one outlet orifice of the dispensing head.
