Abstract
A dispenser adapted to be coupled to a fluid container. The dispenser comprises a dispensing head, an energy source, and a fluid pathway. The dispensing head includes a fluid pump, a motor adapted to power the pump, a trigger adapted to control the motor, and a nozzle orifice in fluid communication with a discharge end of the pump. The fluid pathway has one portion in fluid communication with an intake end of the pump and another portion inside the container. In one embodiment, the fluid pump is a peristaltic pump. The present invention may further include a valve having a membrane for controlling flow through the valve, the membrane having open and closed positions; and an element urges the membrane to the closed position, and a vacuum pressure at one end of the valve may overcome the urging of the element, thereby moving the membrane to the open position.
