Abstract
A fluid dispenser for dispensing liquid detergents, soaps and germicides. A pressure plate imparts a squeezing force to a flexible reservoir containing the liquid material to force the material therefrom. A battery operated photoelectric device is positioned adjacent the dispensing valve which is opened for a timed period upon locating an object such as a hand, near the photoelectric device. Also, a device is provided to control the power to the photoelectric device upon sensing the condition of the ambient room lighting.
