A dispenser comprising a cover housing, main housing, and base housing is provided. The cover housing includes an upper housing including a dispensing mechanism for dispensing cleaning solution from a holding reservoir. The main housing includes a cleaning solution storage reservoir, and a positive-displacement mechanism for electromechanically transporting cleaning solution from the storage reservoir to the holding reservoir. The base housing includes a ratcheting mechanism for causing the positive-displacement mechanism to rotate, and a power-spring mechanism for generating resistance against the ratcheting mechanism. The dispenser further includes a microprocessor configured to receive a signal indicating a sensing system has identified a dispense trigger, relay a signal to a pump motor to operate accordingly, determine that the holding reservoir is to be refilled, and actuate the positive-displacement mechanism to refill the holding reservoir. The dispenser further includes an electrical power system for supplying electrical power to electrical components of the dispenser.

Various liquid dispensers are disclosed. Certain embodiments include a portable liquid dispenser configured for consumer use in dispensing soap, sanitizer, or ingestible liquids. The dispenser can comprise a housing, a reservoir having an interior configured to store a liquid, a fluid pathway having an opening in fluid communication with the interior of the reservoir, a pump comprising a plurality of rollers, each of the plurality of rollers being configured to contact a portion of the fluid pathway in a flexible tube such that each of the plurality of rollers compresses a portion of the flexible tube that is in contact with the roller, a nozzle, a fluid damper in communication with the pump and the nozzle, an electronic control unit in electrical communication with the pump, and a rotation-tracking feedback system in electrical communication with the electronic control unit.

A delivering device (1) is described, in particular for pasty or creamy products preferably for domestic use, comprising at least one delivery duct (3) which puts in fluid communication at least one internal volume (5) of at least one container (7), the internal volume (5) containing therein at least one product, and at least one delivery nozzle (9) for exiting the product by interposing pumping means (11) actuated by at least one actuating motor (13) to transfer amounts of the product from the internal volume (5) to the delivery nozzle (5) through the delivery duct (3), and control means (14) actuated by a user and operatively cooperating with the actuating motor (13) to allow or inhibit at will an operation of the actuating motor (13) and perform or stop a delivery of the product through the delivery nozzle (9).

An applicator and methods of dispensing liquid. The applicator may include a reservoir with a body and a pad. The body may extend around and form a receptacle. The pad may be attached to the body. An actuator may be movably connected to the reservoir and may include a plunger. The plunger may be movable relative to the body in a first direction to drive the liquid from the receptacle and into the pad and a second direction to move the plunger away from the pad.

A dispenser includes a body defining an internal volume and an opening that provides a path of fluid communication between the internal volume and an exterior of the body. A first tubular member extends through the opening. A length of the first tubular member is greater than or equal to about 150% of a height of the body. In response to squeezing the body, a composition in the internal volume flows out of the body through the opening and into the first tubular member.

A fluid dispensing system, fluid reservoir, refill container for refilling the fluid reservoir, and method of refilling the fluid reservoir are provided. The fluid dispensing system includes a refill connection port or nozzle to which a refill container is connected when refilling the fluid reservoir. The fluid reservoir includes a piston head and an actuator for moving the piston head in a first direction and in a second direction. When the piston head is moved in the first direction, the fluid within the fluid reservoir is pressurized, causing the fluid to be dispensed through an outlet of the fluid reservoir. When the piston head is moved in the second direction, a vacuum is created within the fluid reservoir that draws fluid, from the refill container, into the fluid reservoir. The fluid dispensing system includes a valve to enable multiple refill containers to be coupled to the nozzle and/or the refill connection port.
