ABSTRACT:
The head (1) for dispensing a product, comprises a nozzle piece (2) intended to be placed on a container (5) containing the product to be dispensed. This nozzle piece (2) includes a base (4) equipped with a sleeve (6) in which is fastened, by snap-fitting, a component (11) to which a pump (14) is linked. A seal (8) is provided between the nozzle piece (2) and the component (11) in order to interact when this component (11) has been snap-fitted on the sleeve (6) of the nozzle piece. The nozzle piece includes a retainer (R) capable of holding the above-mentioned component in a pre-snap-fitting position in which the seal (8) between component and nozzle piece do not yet interact. A passage (16) is provided between the outer surface of the component (11) and the inner surface of the sleeve (6) in which the component is engaged in the pre-snap-fitting position in order to maintain communication between the inside of the container (5) and the outside, in this pre-snap-fitting position.
