Motorized apparatus for dispensing cake icing
First Claim
1. Apparatus for dispensing a substance such as cake icing or the like from a collapsible container having a nozzle thereon comprising:
- a hand-holdable power unit including an electric motor;
a cartridge detachably connectable to said power unit, said cartridge including a rotatable member adapted to be rotatably driven by said motor when said cartridge is connected to said power unit; and
means for connecting said container to said rotatable member so that said substance is extruded from said nozzle when said member rotates, said container is wound on said rotatable member as the latter rotates and spaced-apart extrusion members on either said power unit or said cartridge between which said container is extendable and against which said container is drawn by said rotatable member to effect extrusion of said substance from said nozzle.

Abstract
Motorized apparatus for dispensing cake icing comprises a hand-held power unit including a multi-speed electric motor and controls, including a trigger switch, for the motor, one or more cartridges detachably connectable to the power unit and each including a rotatable member drivable by the motor, and a collapsible icing bag having a nozzle and containing icing, such bag being detachably connectable to the rotatable member and windable or twistable by the rotatable member so that icing is extruded from the nozzle. The controls operate to cause momentary motor reversal to stop icing extrusion when the trigger switch is released. Each cartridge includes a device to prevent unwinding or untwisting of the bag when the cartridge is removed from the power unit.
