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.

[What is claimed is:] [10.]a dispensing member mountable on a pump or valve surmounting a reservoir containing the product and defining an outlet duct for the product, the outlet duct opening to at least one dispensing orifice;a substantially rigid actuating fitting movable in response to a pressure exerted on the actuating fitting from a first position to a second position, the actuating fitting being configured to come into engagement with the dispensing member during the movement of the actuating fitting from the first position to the second position in order to move the dispensing member from a closed position to a dispensing position in which the outlet duct is in communication with the reservoir; anda shut-off device movable with the actuating fitting from the first position in which the dispensing orifice is closed thereby to a second position in which the dispensing orifice is uncovered to allow the product to exit under pressure, wherein said shut-off device is constructed to elastically return to the first position when the actuating pressure ceases, wherein the shut-off device provides sealing between the dispensing member and the actuating fitting.
