Abstract

A device for the dosed administration of a fluid product including 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 retaining device which maintains the coupling elements in a maintaining position uncoupled from each other, wherein at least one of the coupling elements is displaceable by a coupling movement from the maintaining position into a coupling state, and wherein a driving force of the drive element causes a delivery movement of the conveying device via the coupling elements.
