A wearable dispenser with a replaceable one-time-use reservoir device is taught, comprising a wrist-band allowing the wearable dispenser to be worn by a user; a base connected to the wrist-band; and a replaceable one-time-use reservoir. The replaceable one-time-use reservoir is comprised of a flexible bladder holding a substance to be dispensed, a housing with a rigid perimeter wall, a flexible top surface attached to the rigid perimeter wall and covering the flexible bladder, a one-way valve, an opening, and a substance to be dispensed. Typically, the substance to be dispensed is hand sanitizer. A user may use their fingertip to press the flexible top surface. Doing so creates additional pressure within the flexible bladder, causing the substance to be dispensed.

A system for dispensing a personal care fluid, such as a hand soap or the like. The system includes a dispenser and a refill cartridge. The dispenser includes a dispenser body having a refill cavity and a dispenser lid configured to be coupled to the dispenser body. There may be a pump sub-system mounted to the dispenser lid, or alternatively the personal care fluid may be dispensed by squeezing the dispenser and refill cartridge. The refill cartridge is configured for slidable insertion into and removal from the refill cavity of the dispenser body. The personal care fluid system is designed so that a user can readily and easily change out/replace the refill cartridge for use with a common dispenser, dispenser lid, and pump sub-system.

A hand sanitizer dispensing device and method of dispensing sanitizing fluid are disclosed. The device may be mounted to the stem of a scooter or to the tubes of a bicycle frame. 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. Manual activation is achieved by pulling on a lever of the actuator. Automatic activation is achieved by placing the hand(s) under the dispenser whereby a sensor senses the presence of a hand(s) to dispense the fluid. The device communicates wirelessly with a mobile communication device application allowing the user to purchase use of the dispensing device. User interfaces on the mobile communication device guide the user to execute the purchase and to unlock the device for use.

Among other things, a dispenser for dispensing material is provided herein. The dispenser includes a cover. The dispenser is configured to receive a container from which material is dispensed. The container is adapted to be supported by the cover. Biasing structure is adapted to apply a force to the container to facilitate dispensing the material from the container.

A foam dispenser includes a housing, a drive motor, and a foam pump. The foam pump includes a pump housing, and a molded multi-chamber diaphragm. The molded multi-chamber diaphragm includes a liquid pump diaphragm having a liquid pump stem and two or more air pump chambers each having an air pump stem. The length of the liquid pump stem is longer than the air pump stem. The foam pump further includes one or more outlet valves, a mixing chamber, an outlet for dispensing foam wherein the outlet is in fluid communication with the foam cartridge; and an actuator for sequentially actuating the liquid pump chamber and the two or more air pump chambers, wherein there is lost motion between the actuator and the liquid pump diaphragm.

A refillable solution dispenser including a dispenser housing having a base with a plurality of sidewalls defining an interior volume of the housing. A lid defining the top of the housing located on the top of the sidewalls is movably secured to allow access to the interior of the housing. An actuator mechanism is disposed through a top of the housing. At least one dispensing device is moveably connected within the housing. The dispensing device includes a pressure system connected to the actuator mechanism. The pressure system will move a pressure apparatus located within the housing forcing a solution from a solution reservoir through a dispensing passageway and out of the nozzle.

Apparatuses and techniques are provided for dispensing fluid from a dispenser that includes a flexible membrane having different levels of pliability according to a voltage applied to the flexible membrane. According to some embodiments, a biasing device, such as a spring, is disposed on a first side of the flexible membrane and is configured to apply pressure to the flexible membrane. When a first voltage is applied to the flexible membrane, the flexible membrane becomes sufficiently pliable to enable the spring to flex the flexible membrane, pushing the flexible membrane into a pumping chamber disposed on the opposite side of the flexible membrane relative to the spring. The fluid is stored in the pumping chamber and the flexing of the flexible membrane causes the pumping chamber to compress. Such compression of the pumping chamber forces the pumping chamber to dispense the fluid through a pump outlet.

A foam dispenser includes a housing, a drive motor, and a foam pump. The foam pump includes a pump housing, and a molded multi-chamber diaphragm. The molded multi-chamber diaphragm includes a liquid pump diaphragm having a liquid pump stem and two or more air pump chambers each having an air pump stem. The length of the liquid pump stem is longer than the air pump stem. The foam pump further includes one or more outlet valves, a mixing chamber, an outlet for dispensing foam wherein the outlet is in fluid communication with the foam cartridge; and an actuator for sequentially actuating the liquid pump chamber and the two or more air pump chambers, wherein there is lost motion between the actuator and the liquid pump diaphragm.

A dispenser includes a housing, an inverted container disposed in the housing, a outlet nozzle, a pump, a first check valve, and a second check valve. The pump is disposed between the container and the outlet nozzle. The pump includes a pump inlet a pump outlet, and a pump chamber. The pump chamber is movable between an expanded position and a compressed position. The first check valve is disposed between the pump and the outlet nozzle, and the first check valve has a first cracking pressure. The second check valve is disposed between the first check valve and the outlet nozzle, and the second check valve has a second cracking pressure. The second cracking pressure of the second check valve is greater than the first cracking pressure of the first check valve.

Among other things, a dispenser for dispensing material is provided herein. The dispenser includes a cover. The dispenser is configured to receive a container from which material is dispensed. The container is adapted to be supported by the cover. Biasing structure is adapted to apply a force to the container to facilitate dispensing the material from the container.
