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.

A fluid dispenser comprising: (a) a flexible container for fluid integrally connected to a valve means and an outlet means; (b) a means for imparting a squeezing force to said flexible container; and (c) a proximity detector means connected to a means for opening and closing said valve means; wherein said means for imparting a squeezing force is a pressure plate which is connected to a spring-driven lever which comprises: (i) an extension spring whose axis is near the central pivot point of a first-class lever when said flexible container is full, said spring axis moving away from said pivot point of said lever as said flexible container is emptied; (ii) said first-class level having extremities that comprise the attachment point of said extension spring to the lever and the attachment point of an axle attached to the pressure plate, respectfully; and (iii) said spring having a sufficient length so that the torque increase caused by the increasing distance of the spring center line from the central pivot point as said container empties is more than the torque decrease caused by the lessening extension of the spring caused by movement of the lever as said flexible container empties.
