Abstract
Electrical batteries are integrated with a disposable container of flowable material for powering a dispensing apparatus. The disposable container includes a deformable chamber for containing a predetermined quantity of material to be dispensed, and an electrically energized actuating member deforms the chamber for dispensing the flowable material. The dispensing apparatus is actuated by a photocell system which electrically energizes the actuating member in response to the proximity of a user to the dispensing apparatus without the user contacting the apparatus. The photocell system normally is inactive, and is rendered active by a sensor for detecting the proximity of a user to the apparatus.
