The present invention is a liquid dispenser, with an inner container, and an outer housing. The inner container is designed to hold a bottle in an inverted position so the liquid stuck at the bottom of the bottle may be emptied into the inner container. The inner container also includes an inner surface designed to draw liquid to the center of the inner container. This reduces the amount of liquid that gets stuck at the bottom of the inner container and allows a user to extract all of the liquid from the inner container. The outer housing is designed to cover the inner container hold a pump and cover the inner container. The lotion dispenser also includes suction cups to secure the inner container to a surface and be self-supporting.

A dispenser system has a base. A rear mount is formed on the base and the rear mount is configured to attach to a wall. A front cover is configured to fit over the base. The modular socket is formed in the base. The pump housing is configured to fit in the modular socket as a module. The pump is mounted inside the pump housing. A liquid container bracket retains a bracket socket. The liquid container bracket is mounted to the pump housing. A nozzle bracket retains a nozzle. The nozzle bracket is mounted to the pump housing. The nozzle is connected to the pump by an exit tubing. A liquid container removably connects to the bracket socket. Liquid in the liquid container flows through the bracket socket and then to an inlet tubing. The inlet tubing is then connected to the pump.

An air-assisted, gravity feed amenity fluid dispensing system suitable for use with personal care fluids. The system may be embodied in a fluid dispenser including a support structure attachable to a support surface such as a wall and an openable canister supported by the support structure. The canister defines an internal cavity configured for inserting a recyclable container pre-packaged with the personal care fluid, and a fluid dispensing mechanism including an air pump configured to pressurize and dispense the fluid from the container through a dispensing hole in the canister. The air pump may be manually-operated in one embodiment to pump air into the container and dispense fluid each time a user depresses an actuator button. The personal care fluid may alternatively be filled directly into the canister without use of an insertable fluid container. Plural canisters each containing different fluids may be supported by the support structure.

Exemplary soap, sanitizer and lotion dispensers are disclosed herein. An exemplary dispenser includes a housing; a receptacle for receiving a container; a container of fluid comprising soap, sanitizer or lotion; a pump in fluid communication with the container; a power source; a pump coupled to a motor and pulse width modulation circuitry in circuit communication with the power source and the motor. The pulse width modulation circuitry is initially set to cause a selected dose of fluid to be dispensed at a base speed. A sensor for detecting a parameter indicative of an actual speed of a dispense of the fluid is also included. When the actual speed of the dispense of fluid is less than the base speed or greater than the base speed, the pulse width modulation circuitry adjusts the pulse width to cause the speed of a following dispense of fluid to be closer to the base speed.

A method of filling a fluid dispenser is provided and a method for operating power driven pump in a dispenser is provided.

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 method of determining the volume of fluid contained in a collapsible bottle, the collapsible bottle containing a fluid to be dispensed from a fluid dispenser. The fluid dispenser has a distance measuring sensor, and the collapsible bottle is coupled to the fluid dispenser so that a preselected surface of the collapsible bottle is positioned in a measurement path of the sensor. The fluid dispenser is activated to dispense an allotment of the fluid from the collapsible bottle, the collapsible bottle collapsing in a predictable manner as the fluid is dispensed from the collapsible bottle. The sensor is used to measure a distance between the sensor and the preselected surface of the collapsible bottle, the distance changing predictably as the collapsible bottle collapses. The volume of the fluid contained in the collapsible bottle is determined based on the distance between the sensor and the preselected surface of the collapsible bottle.

Disclosed herein are embodiments of a manually operated liquid dispenser. In any embodiments disclosed herein, the dispenser can include a housing with a volume of space therein, the volume of space having a first end and a second end, a pump sleeve extending into the space of the housing and nearly to a bottom, inside surface of the space, a pump head, a push rod coupled with the pump head and configured to be axially movable within an axial opening extending through the pump sleeve, a passageway extending through at least the pump head and the push rod, the passageway being in fluid communication with the axial opening extending through the pump sleeve and with the volume of space within the housing, and a first valve configured to control a passage of a liquid substance within the volume of space in the housing through a passageway.

A hand sanitizer dispensing device and method of dispensing sanitizing fluid are disclosed. The device may be mounted to a scooter, a bicycle or other transport devices. The device has an outer shell, an inner pod that holds a bag of sanitizing fluid, and a top cover that secures the inner pod to the outer shell. A pump/nozzle assembly communicates with an actuator to selectively dispense the fluid. The device may be operated manually or by automatic activation. The device may communicate wirelessly with a mobile communication device allowing the user to purchase use of the dispensing device remotely. User interfaces of the communication device guide the user to execute the purchase, to unlock the device for use among other available functions. A purchase transaction for use of the dispensing device can be achieved within a communication network with options as to how the dispensing device is unlocked and operated.
