A pump comprises an open-ended hollow body defining a pump chamber and an inlet orifice which communicates with a reservoir. The pump body has four side walls. A piston is mounted for reciprocal movement through a portion of the body and it extends through the upper end of the body. A ferrule is disposed above the body and defines an aperture through which the piston extends. A seal is disposed is disposed between the ferrule and the body, and the seal surround a portion of the piston. A spring is mounted in the body, and the spring actively biases the piston toward the top of the body. The body has a deformable zone which has at least a portion of one side wall which is a noncircular cross-section and is radially elastically deformable. The piston has a portion which blocks the inlet orifice when the piston is depressed a first predetermined distance. The piston has an evacuation duct having a lower duct portion extending through the periphery of the piston which puts the pump chamber in communication with ambient air when the piston is depressed a second predetermined distance sufficient for the lower duct portion to be lower than the seal, the second predetermined distance being greater then the first predetermined distance. The lower duct portion is located sufficiently high on the piston so as to delay the placing of the pump chamber into communication with ambient air by the evacuation duct until after the piston is depressed into the body the second predetermined distance which is sufficiently in excess of the first predetermined distance so as to pressurize the pump chamber and radially elastically deform the deform the deformable zone.

The invention relates to a dispensing valve comprising a body formed of a cylindrical casing of rigid material closed by a cover, in which two seals having fluid-tight joints create a lock chamber inside which moves an atomizer provided with a sliding distributor, guided at its ends, which a return spring placed upstream urges towards the cover. The valve has a sleeve allowing alteration of the volume of the chamber and a front seal formed as a separate member, both formed of semi-rigid plastic material. The seal is disposed immediately adjacent an abutment surface formed in the casing. The design is such that entry of liquid during filling takes place through an auxiilary duct and the front seal and sleeve may be formed as a single member if desired.

An inhaler for powder products comprising a housing having an oral suction mouthpiece, a piston contained within the housing for movement in opposite directions, and an elastic member for urging the piston in one direction. The mouthpiece connects with a chamber in which the piston is located so that inhaling through the mouthpiece draws the piston toward the user's mouth. The piston includes a charging cavity for holding a charge of powder product. The cavity communicates with the internal volume of the mouthpiece as the piston is drawn toward the user's mouth whereby the charge is dispensed and inhaled by the user.

A fluid dispenser device comprising: a fluid dispenser orifice (31); an air duct (32, 51, 52) for air under pressure, said air duct including an upstream end and a downstream end that opens out in the proximity of the orifice (31); an air expeller (4) that is suitable for being subjected to elastic squeezing and relaxation stages, the air expeller (4) being connected to the air duct (32, 51, 52) so that, during elastic squeezing stages, it delivers a flow of air through the air duct until it reaches the orifice (31); and a fluid channel (25, 33) that is connected to the air duct (32, 51, 52), the fluid in the channel (25, 33) being sucked up by the flow of air under pressure by the Venturi effect; the device being characterized in that the air expeller (4) has only a single opening (43) that is provided with a connection sleeve (5) that includes an incoming-air passage (53) that is provided with an air-inlet valve (56; 56b; 56c; 56d) that is suitable for allowing outside air to enter into the air expeller during elastic relaxation stages.
摘要:
A fastener device (1, 2) for fastening a dispenser member (4) on a reservoir neck (51), the device comprising: a ring (1) forming an annular bearing collar (10) for coming to bear against the top (52) of the neck (51), with a gasket (3) possibly being interposed therebetween, and a skirt (11) including a free bottom end (145) and a deformable fastener section (13) that is deformed by thrust on the free end; and a hoop (2) that surrounds the skirt (11) of the ring (1) and constrains the fastener section (13) to deform inwards into contact with the neck (51); the device being characterized in that the deformable fastener section (13) is separated from the free end (145) by a substantially non-deformable bottom section (14) that is in engagement with the hoop (2).
