Apparatus for hands-free dispensing of a measured quantity of material

摘要

An apparatus for automatically dispensing a fluid includes a container (36) for the fluid and a dispense mechanism (28) to control the amount of fluid to be dispensed. A pump actuator mechanism (4) is coupled to an object sensor (42), and operates when an object is detected to enable the dispense mechanism (28) to dispense a measured amount of fluid. A timer is associated with the dispense mechanism (28), and is actuated when the dispense mechanism is operated. The timer disables the dispense mechanism if a given number of dispense events occur with a predetermined time period. This provides an anti-vandal feature.
