A hand cleaning liquid dispenser including a fluid level gauging mechanism with a plurality, preferably three or more, vertically spaced optical sensors located closely adjacent an external of a side wall of the reservoir to each receive electromagnetic radiation transmitted through the side wall from within the reservoir with the electromagnetic radiation sensed originating from an emitter directing the electromagnetic radiation preferably through the reservoir downwardly.

A dispenser for generating ozone containing fluid comprising: drawing atmospheric air into an air compartment, generating ozone within the air compartment from air in the air compartment by conversion within the compartment of oxygen in the air within the compartment into ozone to form ozonated air, discharging the ozonated air from the air compartment, mixing the ozonated discharged air with a flowable fluid to form an ozonated fluid-air mixture, and passing the ozonated fluid-air mixture out a discharge outlet. Preferably, the method is carried out in a dispenser utilizing a piston pump to draw air through a corona discharge ozone generator and to draw liquid from a liquid reservoir and simultaneously pass both the ozonated air and liquid through a foam generator to generate foam.

An antibacterial dispensing bracelet includes a frame having a receptacle receiving a removable cartridge defining an interior reservoir for containing a quantity of antibacterial fluid. A finger-activated pump assembly is mounted to the frame proximate to the receptacle and engages an extraction port in the cartridge for extracting antibacterial fluid. The pump assembly further defines a nozzle port for dispensing the antibacterial fluid therethrough by activation of a piston of the pump assembly being mounted in a housing of the pump assembly and movable between raised and depressed positions. The pump assembly also includes a spring biasing the piston to the raised position and a conduit extending in the cartridge to the extraction port thereof. The conduit, housing, and piston define a fluid pathway between the cartridge and nozzle port. A wristband extends from each side of the frame for securing about an arm of a user.

The present disclosure relates to a non-aerosol foam pump for use in association with an unpressurized liquid container and a foaming element comprising. The pump includes a liquid pump portion and an air pump portion. The liquid pump portion has a liquid chamber with a liquid internal volume and a shuttle liquid piston. The liquid chamber is in flow communication with the unpressurized liquid container and in flow communication with the foaming element. The air pump portion has an air chamber with an air internal volume. The air chamber is in flow communication with the foaming element. The liquid pump portion and the air pump portion have an activation stroke and a return stroke. During the activation stroke the air internal volume is reduced and during a beginning stage of the stroke the liquid internal volume remains the same and during a later stage the liquid internal volume is reduced.

A wearable hand sanitizer apparatus for dispensing sanitizer fluid includes a wristband wearable about a user's wrist. A reservoir in the wristband holds sanitizing fluid. An outlet nozzle selectively dispenses a predetermined quantity of the sanitizing fluid. A dispensing assembly is situated intermediate the outlet nozzle and the reservoir and is in communication with the reservoir for selectively dispensing on demand the sanitizer fluid from the reservoir to a place outside the wristband. A first actuator is normally biased to an unactuated configuration but, when actuated, allows the sanitizer fluid to pass through the dispensing assembly to the outlet nozzle. A second actuator in communication with the first actuator is normally biased to an unactuated configuration that prevents the first actuator from being actuated but, when actuated, allows the first actuator to be actuated to allow sanitizer fluid to pass through the dispensing assembly to the outlet nozzle.

A storage holder 1 for placement in a liquid or foam dispenser, comprising a liquid reservoir 2, a pump 3 and a spacer 4. The liquid reservoir 2 has an opening 5 provided with a plug 6. The pump 3 is provided with an inlet tube 9, which inlet tube 9 is fixed into the opening of the plug by a clamping connection. The spacer 4 is provided with an opening for the inlet tube 9 and provided at its exterior with a means 11 to couple the storage holder 1 to the liquid or foam dispenser. The spacer 4 is positioned between the pump 3 and the plug and fixed into position relative to the plug 6 and relative to the pump 3 only by the clamping connection between inlet tube 9 and plug 6.

Exemplary embodiments of dispensers are disclosed herein. One exemplary dispenser is a soap or sanitizer dispenser. The dispenser includes a housing. A removable and replaceable concentrate container for holding concentrated soap or sanitizer is located within the housing. A concentrate pump is in fluid communication with the concentrate container. A diluent container for holding a liquid is also located within the housing and a diluent pump for pumping the diluent is also included. The dispenser includes a mixing chamber in fluid communication with the concentrate pump and the diluent pump. The dispenser includes an outlet. When concentrated soap or sanitizer is pumped from the concentrate container, it mixes with diluent pumped from the diluent container to form a diluted mixture. The diluted mixture is dispensed at the outlet of the dispenser.

A washable faucet lever with crank-activated detergent dispenser having a lever cartridge having a stem operably coupled to a hand lever and a two-bar linkage configured to rotate in a linkage axis of rotation parallel to and simultaneous with a lever axis of rotation, a detergent reservoir member configured to house a liquid detergent therein and that includes a reservoir valve, an encasement member defining an enclosed region therein and an outlet, and having an outlet valve, wherein the dispenser includes a piston disposed within the enclosed region, coupled to the two-bar linkage, and operably configured to translate within the enclosed region upon rotating the hand lever in the lever axis of rotation to selectively and simultaneously displace the reservoir valve and outlet valve to permit flow of the liquid detergent through an internal channel of the reservoir member, into the enclosed region, and out through the outlet.

Foam generators and foam dispensers are disclosed herein. An exemplary foam generator includes a housing that has a charging chamber. The charging chamber includes an inlet. an upper portion and a lower portion. The lower portion has a tapered section. The tapered section has an upper side and a lower side. The charging chamber includes an outlet that has a smaller diameter than the inlet. A porous foam media is also included. At least a portion of the porous foam media is located within the tapered section. The porous foam media has a first foam density at the top of the tapered section and a second foam density as the porous media extends downward in the tapered section. The second foam density is denser than the first foam density.
