Abstract
A head (4) for dispensing a product under pressure includes a dispensing element (20) intended to be mounted on a pump or a valve (30) surmounting a product reservoir (2) and defining an outlet duct (34) for the product, opening to a dispensing orifice (22). A rigid or semi-rigid actuator (16) is capable of coming into engagement with the dispenser. A shut-off device (18) is integral with the actuator (16) and is capable, in response to a pressure exerted on the actuator, of moving from a first position in which it seals off the orifice (22) to a second position in which the orifice (22) is uncovered so as to allow the product to exit under pressure. The shut-off device (18) is formed of a material that is elastically deformable so that it can return to the first position by elastic return when the actuating pressure ceases.
