Patent ID: 7527178

Claim:
An electronic self contained viscous liquid dispenser, comprising: a housing defining an internal liquid reservoir, said housing including front surface having an opening therethrough adjacent a bottom surface of said reservoir; a dispensing pump mechanism carried by said housing and disposed in liquid communication with said reservoir, said pump mechanism having a delivery end disposed for delivering metered doses of viscous liquid from said reservoir; a mounting assembly configured for mounting on a supporting wall structure, said housing with internal liquid reservoir and dispensing pump mechanism being completely removable from and replaceable relative to said mounting assembly, when attached to said mounting assembly, said housing defining a front visible surface of said dispenser; an electronic actuating mechanism carried by said mounting assembly and comprising a motor driven actuator that engages with said pump mechanism upon insertion of said housing into said mounting assembly; a motor and associated power supply circuitry carried by said mounting assembly, said motor in driving engagement with said motor driven actuator; wherein said dispensing pump mechanism is movable in a horizontal direction relative to said housing for actuation thereof, said motor driven actuator comprising a member slidable in a horizontal path to engage and move said dispensing pump mechanism to a dispensing position; and wherein said dispensing pump mechanism comprises a linearly slidable cylinder having a delivery channel defined therethrough terminating at said delivery end, said cylinder being slidable within a substantially horizontally disposed pump chamber defined within said reservoir, said motor driven actuator slidable in a horizontal path to engage and move said cylinder to said dispensing position within said pump chamber.
