A shut-off system for a dispenser includes a pinch member that moves relative to a guide and which is normally biased against a flexible outlet tube that is disposed therebetween. The flexible outlet tube that carries material, such as soap, supplied from a pump to an outlet nozzle. The pump and the pinch member are in operative engagement with an actuator, such that when the actuator is not engaged, the pinch member closes the outlet tube to prevent residual material retained in the outlet tube from flowing or drooling out of the outlet nozzle. Correspondingly, when the actuator is engaged, the pump is compressed, and the pinch member is moved away from the outlet tube, allowing the material to be pumped through the outlet tube and dispensed from the outlet nozzle.

Shut-off system for a dispenser

A foam soap generator is provided for implementation with various types of foam soap delivery systems. The foam soap generator includes converging air and liquid soap passages at a mixing chamber, where a prefoam is generated for ultimate extrusion through a porous passage member. In one embodiment of the invention, the liquid soap is drawn into an entrainment zone by high velocity air passing through the air passageway and into the mixing chamber.

Foam soap generator

Foam dispenser systems and pumps for use in foam dispenser systems are disclosed herein. A refill unit for refilling a foam dispenser system comprises a container for holding a supply of foamable liquid and a pump housing connected to the container. The pump housing comprises one or more connections for connecting to one or more external air pumps, wherein the air pumps supply air pressure to move the foamable liquid into a mixing chamber and to mix air with the liquid in the mixing chamber and create a foamy air-liquid mixture.

Air-activated sequenced valve split foam pump

A dispensing tube assembly includes a first component delivery tube surrounded by a second component delivery tube. The first component delivery tube provides an axial passage, and an annular passage is defined between the first component delivery tube and the second component delivery tube. A component travelling through the axial passage is diverted to enter the surrounding annular passage and mix with a second component traveling in that annular passage. The premixture formed by this mixture of components is then diverted from the annular passage into a post mix chamber and ultimately dispensed as a foam. A foam media may be employed to homogenous the premixture and create a high quality foam. The dispensing tube assembly is advantageously employed in a dispenser wherein soap and air are advanced through coaxial tubes to be mixed and create a foamed soap product.

A portable liquid dispenser includes a blow molded housing defining a cavity within the entire interior thereof. A centralized walled aperture is provided to receive an appropriate dispensing pump, the pump being configured to extend outwardly in a usable position and to lock in an inwardly position where the dispensing nozzle of the pump does not extend beyond the sidewalls of the dispenser itself. A fill and relief valve is provided to accommodate rapid filling of the dispenser during a manufacturing process, and to accommodate breathing of the container during the dispensing operation such that the unvented pump does not result in any distortion of the dispenser as the liquid therein is depleted.

Portable liquid dispenser

A foam soap generator and pump is provided for receipt by a liquid soap container in a foam soap dispenser. The foam soap generator and pump comprise an air cylinder and a liquid cylinder, integral with each other, and in parallel arrangement. Each receives a respective air and liquid piston, again of integral construction. The pistons are provided with arms having passages therethrough that ultimately bring the liquid and air together under pressure for the generation of foam and extrude of the same through an appropriate screen or open cell foam disk.
