Abstract: Fluid product dispenser, including a fluid product pack (2) defining a fluid product container, a dispensing orifice, and a removable sealing part (25) sealing the dispensing orifice; and a case (1) wherein the fluid product pack (2) is inserted by sliding so as to take the pack out of its case to remove the removable sealing part. The fluid dispenser also includes a stopping feature (16, 26, 265) to limit the sliding of the pack in the case.

Abstract: A fluid reservoir (1) having a neck (11) defining a substantially cylindrical drum (12) and an opening (110), said neck being externally provided with an external thread (13) serving to co-operate with a ring (21) internally provided with an internal thread (210) having the same pitch as the external thread (13) of the neck, the external thread (13) being provided with locking means (16) to prevent the ring from being unscrewed, said locking means comprising at least one projection (16) situated under the external thread (13) on the path of the internal thread (210), said fluid reservoir being characterized in that said projection (16) comprises a ramp (161) on which the internal thread (210) engages during tightening, and a locking edge (162) at the end of the ramp (161) defining therebeyond a locking wall (163) against which the internal thread (210) abuts in the event of unscrewing.

Abstract: A packaging assembly, including a fluid dispenser defining substantially parallel opposite side edges, and a housing having two substantially parallel opposite sides. Each side defines an inside wall, with the two inside walls facing each other, and each inside wall is provided with a respective longitudinal groove which extends over at least a portion of the length of the side. The two resulting grooves are parallel, and at least a portion of each of the opposite side edges of the dispenser are slidably engaged in the corresponding one of the grooves in the housing, so as to enable the dispenser to be slidably extracted from the housing.

Abstract: A fixing member is provided for fixing a fluid dispenser device, such as a pump or a valve, onto a tank or other container. The fixing member comprises a body provided for receiving a dispenser device and fixing the body onto the tank. The fixing member includes an external peripheral cover covering the body, at least in part. The cover comprises of teeth that are designed to bite into the body.

Abstract: A dispenser device without any air intake, such as an airless pump, for dispensing a fluid substance, the device comprising a dispensing chamber (14) of variable volume, which chamber is provided with an inlet (12) equipped with an inlet valve member (51, 53), and is provided with an outlet equipped with an outlet valve member, the dispenser further comprising a piston (3) for causing the volume of the dispensing chamber (14) to vary, closure elements (51; 52; 55; 63) being provided to close off the dispensing chamber (14) in airtight manner, substantially at its inlet (12), prior to it being used for the first time, the device being characterized in that the closure elements are formed by the inlet valve member (51, 53).

Abstract: A metering pump for dispensing a predetermined volume of a liquid or semi-liquid fluid includes a pump body 1, a differential piston 51,52, and a turret 6 secured to a container cap 61. The pump body has a bottom end in communication with the container and a top end 11 capable of being fixed in a desired axial position on the turret. The piston is mounted for fluid-tight sliding in the pump body and has a rest position in which it defines a pump chamber 3, the piston being urged by a return spring 7 towards the turret. The top end 11 of the pump body is axially adjustable within the turret to vary the volume of the pump chamber, and includes integral barb projections 111 that bite into the softer turret material.

Abstract: A device for dispensing of small volume comprises a pump associated with a container of the substance to be dispensed, the pump comprising: a hollow pump body; and a piston sliding inside said pump body in sealing contact with the pump body around a circular periphery of diameter D2; wherein the pump further includes: a push rod including a central channel in which a valve seat is formed, the push rod sliding in contact with the pump body around a circular periphery of diameter D1 less than D2; a punch secured to the piston and capable of bearing in sealed manner against the valve seat; and resilient means urging the piston against the valve seat.

Abstract: Product admission into the working chamber 23 of a precompression pump is accelerated by providing a differential piston 4 with a bore 63 which establishes communication between the inside of a skirt 42 and a shoulder 44. A cylindrical sealing element 60 is fitted over a spindle 41 to be applied against the shoulder 44, level with two annular contacts 64, 65 between which the bore terminates. The sealing element closes the bore on discharge of the precompressed product dose. The sealing element is configured such that, particularly when the pump is idle, it is kept deformed and is therefore applied to the shoulder 44 with sufficient force to guarantee the seal of the two annular contacts 64, 65.

Abstract: A precompression metering pump of the prior art which is otherwise particularly advantageous, is nevertheless difficult to prime because of the high degree of compressibility of the air it initially contains in its pump chamber. The present invention improves this aspect of metering pump operations. It consists in providing additional resilient means (20) and at least one cylindrical part (10) level with the conventional outlet non-return valve of the pump and constituting a second outlet non-return valve. In a particular embodiment, the resilient means and the cylindrical part are received one above the other in the outlet channel (33) of the pump actuator rod (31). To do this, they bear respectively against a choking step (32) in the form of a lug and a shoulder (34) presented by said channel. In normal operation, the differential piston (4) of the pump moves out of the way so that operation takes place as in a prior art precompression metering pump.
