Patent ID: 7779830

Claim:
A dosing device for dosing a medium, said dosing device comprising: a first structural unit including an electrically driven delivery device, a plug-in portion enclosing therein a reservoir for storing medium to be dosed, and an applicator for dispensing the medium, the delivery device being configured to receive electrical energy required to deliver medium to the applicator; a second structural unit including a control unit for actuating said delivery device, and an electrical energy store for electrically powering said control unit and said delivery device, said second structural unit defining therein a receiving chamber which opens through an end of said second structural unit and is configured to house said plug-in portion of said first structural unit, said first and second structural units being wholly separable from one another; a guide arrangement cooperating between said first and second structural units to permit the coupling of said first and second structural units to one another; and an electrical interface cooperating between said first and second structural units and disposed to electrically couple said delivery device of said first structural unit to said energy store and said control unit of said second structural unit without the use of tools, said electrical interface being disposed and configured to supply electrical energy directly to said delivery device and said delivery device receiving electrical energy from said energy store via said electrical interface to thereby power and operate said delivery device upon coupling of said first and second structural units to one another.
