ABSTRACT:
The electric dispensing appliance is designed for a double cartridge and comprises a driving spindle which actuates the two thrust rods. In order to prevent an afterflow of the dispensed composition, the driving spindle is rotatably attached to a connecting piece which is longitudinally displaceable with respect to the housing. A double toggle articulation provides a reversible mechanical connection between the housing and the connecting piece, one lever being connected to the housing, a second lever to the connecting piece, and a third lever to the other ends of the first two levers and to the trigger lever of the appliance. The use of a simple mechanical device such as a toggle joint allows an effective suppression of any afterflow.
