A foam dispenser includes a housing, a drive motor, and a foam pump. The foam pump includes a pump housing, and a molded multi-chamber diaphragm. The molded multi-chamber diaphragm includes a liquid pump diaphragm having a liquid pump stem and two or more air pump chambers each having an air pump stem. The length of the liquid pump stem is longer than the air pump stem. The foam pump further includes one or more outlet valves, a mixing chamber, an outlet for dispensing foam wherein the outlet is in fluid communication with the foam cartridge; and an actuator for sequentially actuating the liquid pump chamber and the two or more air pump chambers, wherein there is lost motion between the actuator and the liquid pump diaphragm.

An adaptor assembly for use in a dispenser for a replaceable fluid container comprising a fluid reservoir and a fluid pump. The adapter assembly is used in conjunction with the dispenser to allow a use of a fluid container having a pump being actuated by laterally compressing it. The adaptor assembly comprises an actuation part being movable, when mounted in the dispenser, and comprises a first contact surface for abutting against the user actuator and a second contact surface for abutting against the pump. The adaptor assembly also comprises a first connecting support for removably connecting the actuation part to the dispenser and/ or the fluid dispensing package mounted in the compartment. A fluid dispensing system including the adaptor assembly is also disclosed.

A pump assembly for generating and dispensing of particles of a solid material with or without dispensing of a fluid. The pump assembly preferably includes a fluid pump which in a cycle of operation draws the fluid through a fluid inlet and dispenses the fluid out a fluid outlet. The pump assembly carries a block of the solid material coalesced together and a rasp member, which during the cycle of operation, moves relative the rasp in engagement with the block whereby the rasp member disengages particles of the solid material from the block which particles drop under gravity downwardly adjacent the fluid outlet, for example, onto a user's hand as in the case that the fluid is a hand cleaning fluid and the solid is a solid soap.

Provided is a fluid dispenser comprising a flexible container that contains the fluid, a rigid outer container that houses the flexible container, a dispensing member for drawing the fluid out from the flexible container, and optionally an interconnection piece. Also provided is a kit and a method thereof.

A deformable sleeve (100) is provided configured to at least partially encase a bottle from which a liquid is dispensable upon pressing the sleeve (100), the sleeve (100) comprising a first sensor (7) configured to measure a force applied onto the sleeve (100) and a second sensor (8) configured to measure a permittivity of a content encased by the sleeve (100). In addition, a measurement unit (300) is provided configured to be mounted on the sleeve (100), the measurement unit (300) comprising a processing unit (37) configured to determine at least one parameter associated with the bottle based on at least one of a signal of the first sensor (7) and a signal of the second sensor (8). A corresponding method of retrievably storing the at least one parameter is also provided.

Exemplary embodiments of energy efficient foam pumps and dispensers are disclosed herein. An exemplary foam dispenser included a housing, a reservoir for holding a foamable liquid, a motor, a motor shaft, and a turbine air pump. The turbine air pump is connected to the motor shaft. A cam is also attached to the motor shaft and is used for driving a liquid pump. Liquid from the liquid pump and air from the turbine air pump are mixed in a mixing chamber and dispensed through an outlet nozzle. The touch-free foam dispenser further includes a sensor for sensing an object, circuitry for receiving a signal from the sensor indicative of an object being present and circuitry for energizing the motor to dispense fluid in the form of a foam.

A dispensing system includes a housing including a cover portion attached to a base portion. The cover portion includes an opening. The dispensing system includes a dispensing assembly within which a material is contained and from which the material is dispensed. The dispensing assembly is supported within an interior of the base portion and in fluid communication with the opening. At least one of the cover portion is movable relative to the base portion or the base portion is moveable relative to the cover portion. A position of the cover portion relative to the base portion is adjusted between a first position, in which the cover portion does not engage the dispensing assembly such that the material is not dispensed through the opening, and a second position, in which the cover portion engages the dispensing assembly such that the material is dispensed through the opening.

A dispenser having a housing, a container disposed in the housing for holding a liquid, a nozzle, and a pump. The pump includes a pump inlet, a pump outlet, a pump chamber. The pump inlet is in fluid communication with the container and the pump chamber, and the pump outlet is in fluid communication with the pump chamber and the nozzle. The pump chamber is movable between an expanded position and a compressed position. A first check valve is disposed between the container and the pump, and the first check valve has a first cracking pressure. A second check valve is disposed between the first check valve and the pump, and the second check valve has a second cracking pressure. The first cracking pressure of the first check valve is greater than the second cracking pressure of the second check valve.

Table top sanitizer dispenser bottle bases are disclosed herein. An exemplary table top sanitizer dispenser bottle base includes a movable upper housing, the upper moveable housing has a floor with an aperture located therein and a peripheral wall. The top sanitizer dispenser bottle includes a lower stationary housing. The upper movable housing is connected to the lower stationary housing and is configured to move linearly upward and downward with respect to lower stationary. One or more biasing members bias the upper movable housing upward.
