A foaming unit for producing foam from a mixture of gas and liquid. The foaming unit comprising a housing, a slide, a foaming element, an inlet for the mixture of gas and liquid and an outlet, the slide and the housing being movable relative to each other, the foaming element being arranged hydraulically between the inlet and the outlet, wherein an active volume of the foaming element can be adjusted by changing the relative position of a control edge and an end face of the foaming element.

A foam dispenser utilizing components made from the same or similar materials that can be recycled in a single recycling process or stream includes a plastic spring system acting on spring cones formed in a piston rod and an accumulator, an air valve having multiple flanges to facilitate the flow of air into and out of the foam dispenser, and a liquid piston configured to improve the control of liquid flow through the foam dispenser and which is more easily manufactured.

An exemplary foam dispenser includes a housing, a drive motor and a foam pump operatively coupled to the drive motor. The foam pump is secured to the housing and the foam pump includes a housing and a molded multi-chamber diaphragm. The molded multi-chamber diaphragm includes a liquid pump chamber, two or more air pump chambers; and an outlet valve. A mixing chamber is included and located downstream of the outlet valve for mixing foamable liquid from the liquid pump diaphragm with air from each of the two or more air pump chambers. In addition, a foam cartridge and an outlet for dispensing foam are also included.

Systems and apparatuses include a prime mover, a pump driven by the prime mover, and a sprayer receiving a flow of water from the pump. The sprayer includes a sprayer housing, a first fluid reservoir coupled to the sprayer housing, a second fluid reservoir coupled to the sprayer housing, a chemical selector coupled to the sprayer housing and movable between a first chemical position and a second chemical position, a high pressure selector coupled to the sprayer housing and movable between a high pressure position and a chemical spray position, and a nozzle assembly in communication with the chemical selector and the high pressure selector.

A foam discharge container, including a container main body for accommodating a liquid composition and a foam discharge device which mixes the liquid composition with air and discharges it in a foam form. The foam discharge device has a plurality of porous bodies through which the liquid composition passes when the liquid composition is discharged, the plurality of porous bodies include a tip side porous body arranged in a vicinity of a discharge port of the foam discharge device, and the tip side porous body is composed of polyethylene terephthalate.

Foaming cartridge for use with a foam pump, refill unit or foam dispenser includes a housing and a foaming stage disposed within the housing. The foaming stage includes two or more mix media located within the foaming stage. At least two of the mix media are sponges and the sponges have different porosities.

A spray device comprises a container for detergent, a spray head for mounting on the container, and a liquid supply for transferring liquid from the container to the spray head. The spray head comprises: a body, a chamber in communication with the atmosphere, an elongate outlet bore extending to an outlet of the body, a detergent inlet aperture in a surface of the chamber, communicating with the liquid supply for communication with the interior of the container, and a water inlet for the chamber. The water inlet is configured to direct a jet of water over the detergent inlet aperture towards the outlet bore. Passage of the water jet over the inlet aperture causes detergent from the container to be drawn into the chamber. The inner surface of the foam generating outlet bore is formed as an aerating surface. Spray heads for use with such spray devices are also disclosed.

An exemplary tabletop foam sanitizer dispenser includes a reservoir for containing liquid sanitizer. The bottle has a base for sitting on a surface. The base has a base diameter. The bottle has a top and a neck located proximate the top having an opening. The opening has an inner neck diameter. The base diameter is at least 3 times the inner neck diameter. A pump assembly is also included. The pump assembly has a cylindrical housing. The cylindrical housing having an outer housing diameter. The outer housing diameter is less than the inner neck diameter. The cylindrical housing is inserted into the bottle through the neck opening. A pump is located in the cylindrical housing. The pump includes a liquid inlet, an air inlet, a liquid outlet and an air outlet. A pump is motor located in the cylindrical housing. A battery is also located in the cylindrical housing. A nozzle housing is located above the cylindrical housing. A liquid and air mixing chamber located in the outlet nozzle housing. The liquid and air mixing chamber is in fluid communication with the liquid outlet and the air outlet. An outlet nozzle is in fluid communication with the mixing chamber and is located in a lower portion of the nozzle housing. The table top dispenser further includes a sensor for detecting a hand of a user positioned below the nozzle.

A foam dispenser utilizing components made from the same or similar materials that can be recycled in a single recycling process or stream includes a plastic spring system acting on spring cones formed in a piston rod and an accumulator, an air valve having multiple flanges to facilitate the flow of air into and out of the foam dispenser, and a liquid piston configured to improve the control of liquid flow through the foam dispenser and which is more easily manufactured.
