Patent ID: 8070024

Claim:
A nozzle for dispensing a liquid contained in a receptacle, said nozzle comprising a rigid body provided with a dispensing channel that is intended to be put in communication with an inside of the receptacle, said channel comprising a dispensing orifice emerging in a front wall of said rigid body, said nozzle also comprising an elastically deformable sleeve that is disposed in a non-adhering fashion and in clamping contact around at least part of a periphery of said rigid body, said sleeve being provided with at least one front lip that is disposed opposite the dispensing orifice, said lip being arranged so as, by application of dispensing pressure of the liquid on said lip, to be reversibly movable between a stable closed state and a stressed state of opening of said orifice, said nozzle being characterised in that an attachment of said sleeve to said rigid body is achieved in combination by a first means of retaining axial movement of a rear part of said sleeve relative to said rigid body and by a second means of retaining axial movement of another part of said sleeve relative to said rigid body, said other part being disposed between the rear part and the front lip of said sleeve, characterised in that a downstream orifice has an insert centered axially so as to form liquid passages around the insert, the sleeve comprising a radial lip that surrounds said insert sealingly in a closed state.
