Abstract: A dispensing device for fluid products comprises a receptacle having a neck (1) with a cylindrical bore and a lip (4) having a redan (4b). A pump body (2) encloses a piston pump mechanism with an axial nozzle. The body of the pump (2) is sealingly mounted on the receptacle by a sleeve (9), a skirt (5) provided on an internal wall with a transverse partition (7) having a central opening (8) adapted to receive the body of the pump (2) and a sealing joint (11) disposed between the body of the pump (2) and the lip (4) of the neck (1) of the receptacle. The skirt (5) is of an elastically deformable material, the skirt (5) having at an upper end thereof a right cylindrical portion (5a) whose external diameter is substantially equal to the internal diameter of the sleeve (9), and below the upper portion (5a) a truncated conical portion (5b) flaring outwardly downwardly and whose height is at least as great as the height of said lip (4) of the neck (1) of the receptacle.

Abstract: Miniature dispenser (1) comprising a receptacle (2) constituted by a reservoir (3) and a cylindrical neck (4), a cylindrical sleeve (5) carrying a piston pump mechanism having an axial nozzle, the sleeve (5) being engaged within the neck (4) of the receptacle (2), the external periphery of a lower skirt of the sleeve (5) being gripped by cone-on-cone engagement about an internal periphery (4a) of the neck (4) of the receptacle (2) and the sleeve (5) comprising, on an external wall (5b) thereof, an annular projection (13) bearing on an upper edge of the receptacle (2). The external periphery of a lower skirt of the sleeve (5) and the internal periphery (4a) of the neck (4) have snap-in formations (14, 15) that are mutually engagable. An internal wall (5a) of the sleeve (5) comprises a peripheral abutment (19) directed toward the interior of the sleeve (5).
