A dispenser pump is constituted by a closure body (2), a diaphragm body (3) which forms a pump chamber with the closure body and optionally a top actuator (4) for pressing the diaphragm body (4). The diaphragm body has a deformable wall (35) formed integrally in the same polymer as its annular mounting portion (31). An inlet valve (5) through the floor (21) of the closure body has a flap (52) which is formed and hinged integrally with that floor (21). An outlet valve may also be formed in the same polymer, either integrally with the diaphragm body or as a separate component. The deformable wall of the diaphragm body is shaped to generate a restoring force itself without a separate spring, so that the entire pump may be made from the same polymer e.g. polypropylene and without metal components.

A fluid dispenser comprising a dispenser member (1), such as a pump, a dispenser head (14), such as a fluid applicator, and a fluid reservoir (2) that is connected in leaktight and removable manner to the dispenser member (1), the fluid dispenser being characterized in that the sealing between the dispenser member (1) and the fluid reservoir (2) is obtained by coaxially sliding leaktight radial contact that is interrupted when the fluid reservoir (2) is disconnected from the dispenser member (1), such that the fluid reservoir (2) is connected in leaktight manner to the dispenser member (1) over a determined axial height range.

A dispensing pump mechanism is provided. The pump comprises integrally molded temper-evidence part between a container collar and a spout; said collar has multiple off-centre outlet channel for dispensing one or more products from the container; said collar also comprises an integrated air vent to be blocked and opened by the rotation of the spout. The whole pump can be over-molded one-piece structure with elastic parts as being actuating parts. The pump improves the functions of the pump, such as lower restitution rate, less structural parts, lower cost, water/dust proof, lightweight, easy assembly.

A fluid dispenser assembly having a fluid reservoir (R), a dispenser member (5), and a dispenser orifice (62). The fluid reservoir (R) includes a piston (42) movable in leaktight sliding contact in a slide cylinder (41) over a maximum stroke between a start position that corresponds to a substantially full state of the reservoir, and an end position that corresponds to a substantially empty state of the reservoir. The dispenser assembly has a detector (35) arranged outside the fluid reservoir (R) and acts remotely to detect a determined physical property that enters into a small detection field that covers an alert position of the piston that is closer to the end position than to the start position. The piston (42) carries the detectable determined physical property and the detector (35) delivers, in response to a detection of the physical property, at least one alert signal perceptible to a user.

Apparatuses and techniques are provided for dispensing fluid from a dispenser that includes a flexible membrane having different levels of pliability according to a voltage applied to the flexible membrane. According to some embodiments, a biasing device, such as a spring, is disposed on a first side of the flexible membrane and is configured to apply pressure to the flexible membrane. When a first voltage is applied to the flexible membrane, the flexible membrane becomes sufficiently pliable to enable the spring to flex the flexible membrane, pushing the flexible membrane into a pumping chamber disposed on the opposite side of the flexible membrane relative to the spring. The fluid is stored in the pumping chamber and the flexing of the flexible membrane causes the pumping chamber to compress. Such compression of the pumping chamber forces the pumping chamber to dispense the fluid through a pump outlet.

Various implementations of the invention are directed toward a sanitizing door handle and/or components of such sanitizing door handle. Some implementations of the invention are directed toward a manual sanitizing door handle while some implementations of the invention are directed toward an auto-sanitizing door handle. According to some implementations of the invention, a sanitizing fluid is dispensed directly onto an exterior surface of the sanitizing door handle in connection with an operation of the door handle to sanitize the door handle. According to some implementations of the invention, a sanitizing fluid is dispensed directly onto a user's hand(s) in connection with an operation of the door handle to sanitize the user's hand(s).

The invention is directed to a dispensing device comprising a rigid container, a flexible bladder, and a rigid stopper. The container is adapted to contain a product to be dispensed. The flexible bladder is disposed below and in fluid communication with the container. The bladder comprises a top end, a sidewall extending downwardly from the top end and terminates in a spout. The bladder is in a liquid tight engagement with the container and the product contained in the container is adapted to flow into the bladder. The rigid stopper is disposed within the flexible bladder and comprises a top end, and at least one sidewall extending downwardly from the top end, and terminates in an open bottom end. The stopper comprises a plurality of through holes.

An airless eye cream container is proposed. The container includes an airless pump installed to be very suitably used for an eye cream cosmetic container so as to store eye cream cosmetics exclusively to block the introduction of external air or foreign substances and prevent contamination and deterioration of cosmetics, and a predetermined amount of eye cream can be accurately discharged and used by operating the pump in use to not only improve the convenience of use, but also reduce the waste of cosmetics.

A dispensing head including a cap having: an outer wall with at least one part referred to as the shell part and at least one part referred to as the pressing part that is made of a material more flexible than the at least one shell part; at least one outlet; an insertion orifice, a stopper, the stopper being mounted in the cap by being inserted into the cap from the insertion orifice side and in an insertion direction, at least one assembly, each assembly including: an inlet, passing through the stopper; a deformable pocket, an interior volume of which is intended to contain the fluid of this assembly and is delimited at least in part by the at least one pressing part of the cap; preferably a feed duct and/or a dispensing duct.
