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. The skirt (5), below the truncated conical portion (5b), has a straight cylindrical portion (5c) whose diameter is substantially equal to the largest external diameter of the truncated conical portion (5b). The skirt (5) has on an internal surface thereof, substantially at the level of a junction between the truncated conical portion (5b) and the lower straight portion (5c), a projection (10) extending radially inwardly of the skirt (5).
