Abstract
A nozzle for dispensing a liquid contained in a receptacle, the nozzle including a rigid body provided with a dispensing channel including a dispensing orifice emerging in the front wall of the body, the nozzle also including an elastically deformable sleeve that is disposed in a non-adherent fashion and in clamping contact around at least part of the periphery of the rigid body, the sleeve being provided with at least one front lip that is disposed opposite the dispensing orifice, the lip being arranged so as, by application of the dispensing pressure of the liquid on it, to be reversibly movable between a stable closed state and stressed opening state of the orifice, in which the attachment of the sleeve on the rigid body is achieved in combination by a first attachment for retaining the axial movement of the rear part of the sleeve relative to the rigid body and by a second attachment for retaining the axial movement of another part of the sleeve relative to the rigid body.
