Patent ID: 8409148

Claim:
A device for the dosed administration of a fluid product comprising a housing, a conveying device for the product, a drive element influenced by the selection of a product dose, a coupling input member coupled to the drive element, a coupling output member coupled to the conveying device, a holding means arranged between the coupling input and output members which maintains the coupling input and output members in a holding position uncoupled from each other, wherein at least one of the coupling input and output members is displaceable relative to the other by a coupling movement from the holding position into a coupling state in which the coupling input and output members establish an engagement, wherein a driving force of the drive element causes a delivery movement of the conveying device via a movement of the engaged coupling input and output members in the coupling state, and wherein the coupling output member is fixed axially and rotationally relative to the casing in the holding position of the coupling members.
