The present invention provides a foam dispensing unit (10) that dispenses a content liquid in a foamed state by causing the content liquid pumped out via a liquid flow channel (23) to pass through a porous member (29) provided in a foaming flow channel (24) together with air, the foam dispensing unit including a mechanism for variably positioning a passage surface (40), the mechanism rotatably holding the porous member (29) in the foaming flow channel (24) to variably position a content liquid passage surface of the porous member (29). The mechanism for variably positioning a passage surface (40) includes a loosely holding region (41) formed in the foaming flow channel (24) and the porous member (29) loosely mounted in the loosely holding region (41). The porous member (29) has a spherical shape, and freely rotates inside the loosely holding region (41) due to an action of a stream of the content liquid passing through the loosely holding region (41), so as to replace a surface thereof in a pass-through direction.

A dispenser for dispensing ozone containing foam. The dispenser comprises an ozone generating chamber having an air inlet in communication with a source of air and an air outlet. The ozone generating chamber contains a corona discharge generator that generates a corona discharge to produce: (a) ozonated air, by converting oxygen in the air into ozone, and (b) an ionic wind. The ionic wind draws the air from the air source into the ozone generating chamber through the air inlet, and expels the ozonated air from the ozone generating chamber through the air outlet. A foam generator receives the ozonated air expelled from the ozone generating chamber and mixes the ozonated air with a foamable liquid to generate the ozone containing foam.

A fluid dispenser includes a housing, a pump, an outlet nozzle, a reservoir, a liquid passage, an air passage, and a refill container. The pump and reservoir are attached to the housing, and both the outlet nozzle and the reservoir are in fluid communication with the pump. The reservoir has at least one engagement member, and the liquid passage and the air passage are located in the engagement member. The refill container has at least one sealing member, and the refill container is configured to be releasably attached to the reservoir such that the refill container is in fluid communication with the reservoir. When the refill container is attached to the reservoir, the engagement member engages the sealing member to cause the liquid passage and the air passage to be in fluid communication with the refill container.

A piston pump for dispensing fluid from a reservoir, an improved vacuum relief arrangement in which a passageway for flow of air from the atmosphere into the reservoir is provided at least in part through a piston-forming element of the piston pump.

A fluid dispenser having a pump mechanism that dispenses a dose of fluid when a movable pump member of the pump mechanism is moved between an extended position and a retracted position. A pump engagement body engages with the movable pump member for effecting movement of the movable pump member. A first cam surface and a second cam surface are connected to the pump engagement body, at least one of the first cam surface and the second cam surface comprising an adjustable cam surface whose location relative to the pump engagement body is selectively adjustable. A camming body engages with the first cam surface and the second cam surface to effect movement of the pump engagement body, and a dose adjustment mechanism allows the location of the adjustable cam surface relative to the pump engagement body to be selected.

Disclosed in the present invention is a pump type dispenser which includes a pump held by a mouth portion of a container and configured to suction and pressure-feed a content liquid in the container, and a nozzle head having an internal passage through which the pressure-fed content liquid passes and driving the pump by being repeatedly pushed down and restored. The internal passage includes a vertical passage, a lateral passage, and a protrusion protruding toward an inner side in a joining portion between the vertical passage and the lateral passage, and a dispensing member disposed in the lateral passage includes a recessed portion which engages with the protrusion to prevent separation from the lateral passage.

A foaming component for use in a foaming liquid dispenser, and an insert arranged so that it may be inserted into a liquid dispenser comprising the foaming component. The foaming component comprises a liquid chamber; an air chamber; a sparging component, which comprises a sparging interface and a foaming region; an exit aperture; and a pumping mechanism. The pumping mechanism is arranged such that it can transfer liquid from the liquid chamber directly to the foaming region, and air from the air chamber to the foaming region, via the sparging interface. The forcing of air through the sparging interface causes bubbles to form in the liquid located in the foaming region, resulting in a foamed mixture for dispensing. The pumping mechanism is then used to transfer the foamed mixture from the sparging component through the exit aperture, wherein the sparging interface is arranged such that at least a portion of the foaming region is positioned in between opposing surfaces of the sparging interface.

A dispenser includes: a container that stores a liquid; a pump unit, and a cover member for housing the pump unit in the container. The pump unit includes: a liquid delivery mechanism configured to take a liquid suction action and a liquid delivery action; a case part in which the liquid delivery mechanism is arranged and has an inner communication hole for providing air communication between the inside and the outside of the case part; and an inner opening-closing part that opens the inner communication hole in the liquid delivery action of the liquid delivery mechanism, and closes the inner communication hole in the liquid suction action. The cover member includes: a cover body that has an outer communication hole for providing air communication between the inside and outside of the case part; and an outer opening-closing part that opens and closes the outer communication hole according to the pressure in the container.

A foaming dispenser has a mixing chamber configured to mix a liquid and a gas to foam the liquid, a first liquid passage configured to supply the liquid to the mixing chamber, and a discharge opening configured to discharge the foamed liquid, the mixing chamber includes a plurality of second liquid passages branching and extending from the first liquid passage, a liquid passage meeting where one second liquid passage meets another second liquid passage, a gas passage configured to supply the gas to the liquid flowing from the plurality of second liquid passages to the liquid passage meeting, and a hole that is provided on a downstream side of the gas passage and communicates with the discharge opening.

A soap dispenser including a rigid cartridge, an inverted dispensing pump, a collar carrying a lever for actuating the pump, and a venting system for equalizing the air pressure in the rigid cartridge, wherein the rigid cartridge and the collar cooperate to removably attach the soap dispenser to a wall-mounted bracket, and further wherein at least the rigid cartridge is disposable and can be made of a recyclable and/or biodegradable material.
