A pump for a receptacle (10), in particular a bottle intended to contain a cosmetic product. The pump (1) has a pumping chamber (8) with a variable volume defined at least partly by a deformable membrane (3). The pump (1) functioning by varying the volume of the chamber (8) by elastic deformation of the membrane (3) between an initial state in which the chamber (8) has a maximum volume and a deformed state in which the volume of the chamber (8) is minimum. The chamber (8) being provided with an inlet orifice (22) and an outlet orifice for the product. The pump (1) has a means for deforming the membrane configured to exert a pressure on the membrane (3) and a guide rod (20) passing through the membrane (3). The membrane (3) slides along the rod (20) when it undergoes said deformation.

A pump dispenser has a deformable pump chamber constituted by first and second part-chambers each having a respective resiliently deformable faceted chamber wall and a connecting conduit communicating between them. They may be moulded in one piece and require no separate restoring spring. The first and second part-chambers may be disposed in line between a pump body providing an inlet valve from a container and a movable actuator cap providing a valved outlet.

A device for dispensing a product includes: a module including a head and a reservoir, the head including a conduit connecting the inside of the reservoir to an outlet of the head; and a housing having at least two mutually movable parts including an upper part and a lower part, the at least two parts being arranged to be assembled so as to receive the module inside the housing.

An orientation independent delivery device. The delivery device includes a gas chamber, a delivery chamber, a gas cell, and a delivery aperture. The gas chamber includes a gas-side rigid portion and a gas-side flexible barrier. The gas-side flexible barrier is sealed to the gas-side rigid portion. The delivery chamber includes a delivery-side rigid portion and a delivery-side flexible barrier. The delivery-side flexible barrier is sealed to the delivery-side rigid portion and is oriented adjacent to the gas-side flexible barrier. The gas cell is coupled to the gas-side rigid portion of the gas chamber. The gas cell increases a gas pressure within the gas chamber to expand the gas-side flexible barrier. Expansion of the gas-side flexible barrier applies a compressive force to the delivery-side flexible barrier allowing a delivery material to escape from the delivery chamber.

The present invention provides an improved pump assembly incorporating a liquid pump and an air pump and which pump includes a flexible annular diaphragm member coaxially about a piston-forming element forming a component with the liquid pump.

The invention relates to a device (1) intended to contain and dispense a cosmetic substance (2), said device (1) comprising: •a container (3) that forms a 5 leaktight volume (4) having an orifice (5) through which the cosmetic substance (2) is introduced so as to be stored temporarily in said leaktight volume (4); •a closure means (6) for shutting off said orifice (5) in the container (3); characterized in that said closure means (6) has: •a detection member (7) for detecting actuation of said closure means (6) with a view to taking said cosmetic 10 substance (2); •a communications interface (8) for transmitting the information output by said detection member (7) to an external data server (12).

A liquid dispenser, having a large ring, a connecting cover, and a hollow pump frame, the pump frame is movably clamped to the interior of the large ring, the top of the pump frame extends to the outer side of the top of the large circle, a bottom protruding portion of the connecting cover extends into a top groove of the pump frame so as to be movably clamped thereto, a first air outlet is provided on both sides of the bottom of the connecting cover, and a second air outlet in communication with the first air outlet is provided to penetrate through the pump frame. The first air outlet, the second air outlet, the first liquid outlet, and the second liquid outlet can be opened and closed by rotating the connecting cover to change a position relationship between the connecting cover and the pump frame

A dispenser for discharging pharmaceutical liquids, in particular in the form of individual drops. Such a dispenser is designed as a side-actuation dispenser with an actuation button on the dispenser in the region of a lateral surface of the housing and has a liquid store, a pump device with a pump chamber which has a variable volume, and a dispensing opening for dispensing the liquid. The actuation button is a spring-loaded toggle switch, the volume of the liquid channel is reduced using an insert, and a special housing design is provided for the purpose of adapting the dispenser to the customer's needs.

A pump constructed entirely from a polymeric material is described. The pump includes an internal sealing plug and adaptable insert coupled to a resilient bellows structure. The plug includes a keyed feature that allows for selective sealing at the lower end of the pump chamber depending upon the rotational alignment of the actuator head and closure, owing to stopper mechanisms appropriately positioned along the peripheral interfacing surfaces of these components.

The present invention relates to a modular closure device (7) for a device for dispensing a product, comprising: —an outlet nozzle (9) comprising: an outlet orifice (15) at the front, a rear opening, a product intake orifice, —top valve comprising a shut-off member (17) that closes of the outlet orifice, a deformable membrane (22) that seals the rear opening closed, designed so that a depression inside the nozzle forces the shut-off member toward its closed position, and a rigid frame extending between the outlet orifice and the membrane; —a bell housing having an end wall and base opening opposite this end wall, the edges of the base opening being fixed to the nozzle, the membrane sealing the base opening closed. The invention also relates to a dispensing device comprising this closure device.
