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 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 product dispenser mounting system includes a dispenser holder body configured to support a product dispenser; and a mounting apparatus configured to fixedly mount on a support object and to removably connect to the dispenser holder body in one or more orientations such that dispenser holder body is maintained in a selected one of the one or more orientations when the dispenser holder body is connected to the mounting apparatus. The system may also include at least one actuation sensor configured to detect actuation of the product dispenser.

A fluid dispensing system including a fluid dispenser that is operable in a stand-alone mode, and a housing that is configured to removably receive the fluid dispenser for operation of the fluid dispenser in a housed mode. When the fluid dispenser is placed on top of a horizontal support surface for operation of the fluid dispenser in the stand-alone mode, a pump mechanism of the fluid dispenser is manually activatable to dispense an allotment of fluid by manually depressing an activation member of the pump mechanism. When the fluid dispenser is received by the housing for operation of the fluid dispenser in the housed mode, the pump mechanism is activatable by activating an actuation mechanism of the housing.

A dispenser for dispensing soap and sanitizer includes a back plate, a container insert removably securable to the back plate, and a cover pivotally engaged to the back plate and the container insert. The container insert includes a first side defining a first container receiving feature and a second side, opposite the first side, defining a second container receiving feature that has a different configuration or size than the first container receiving feature.

An exemplary dispensing system includes a dispenser, an actuator, a sensor, and a controller. The dispenser includes a container for holding liquid, a liquid pump, an air pump, an outlet nozzle, and a foaming media. The actuator causes the dispenser to dispense liquid or foam. The sensor generates an input signal indicative of a status of the container. The controller receives the input signal, generates at least one output signal, and prevents the dispenser from dispensing liquid or foam if a breach is detected in the container.

An inductive soap dispenser includes a soap dispenser body, a liquid soap tank and a base. An inductive circuit board, a self-priming pump and a battery are provided inside the soap dispenser body. The inductive circuit board is configured to control the self-priming pump to siphon liquid soap from the liquid soap tank, and the battery is configured to supply working power to the self-priming pump. The base is a suction device. The top of the suction device is fixedly connected to the liquid soap tank, and the bottom of the suction device is absorbed onto an object surface. The improved inductive soap dispenser is easy to move, stable in fixation, and aesthetically pleasing in appearance, which is broadly applied to shopping malls, hospitals, schools, office buildings, hotels and other public places.

A dispenser of liquid products for sanitization, such as bactericides, germicides, disinfectants, alcohol gel, moisturizers, among others, featuring innovative construction characteristics which distribute the product onto the user's hands or onto surfaces of various objects, via spraying in micro droplets, enabling a uniform distribution, suitable to be installed in public environments such as restrooms, restaurants, malls, offices and commercial facilities.

A soap dispensing shower assembly for a shower enclosure to free a hand of the user for enhanced stability includes a reservoir, a pump, and a tube. The reservoir is mountable to a wall proximate to a water inlet of a shower enclosure. A liquid soap solution is positionable in the reservoir. The pump is engaged to and positioned within the reservoir. The tube is engaged to the pump and extends from the reservoir. The tube extends along a hose extending between the water inlet and a spray head so that a terminus of the tube is positioned proximate to the spray head. The pump selectively dispenses the liquid soap solution through the tube onto a user.

The invention provides an improved machine for generating soap foam that includes a single drive, such an electric motor or human-driven crank that simultaneously drives both a pump, such a peristaltic pump, and a blower. Soap solution is delivered in front of the blower in a waterfall-like manner by gravity so it can be urged through a fine mesh fabric screen to introduce air for the formation of soap foam. The motor speed, drive gearing for the pump, the fan turbine for the blower and soap solution nozzle configuration are selected to provide soap foam of the desired volume, density, and flow.
