Patent ID: 6935541

Claim:
A device for dispensing a viscous product, the device comprising; a housing component having a cavity and a dispensing orifice; a movable wall positioned in said cavity operable to separate a product enclosure from a gas enclosure; a fluid passage providing fluid communication between a pressurized gas source and said gas enclosure; a manually actuated control valve associated with said pressurized gas source, said control valve having an actuator which, upon actuation, is adapted to release gas from said pressurized gas source into said fluid passage and said gas enclosure; a pressure relief valve in fluid communication with said gas enclosure; an operator-activated trigger mechanism operable to open said orifice; and a second operator-activated trigger mechanism located adjacent said actuator of said control valve and operable to engage said actuator; wherein said movable wall is configured to move in response to a force exerted by said pressurized gas enclosure so as to cause the viscous product to dispense from said orifice.
