Abstract:
1. A device for administering a fluid product, comprising a first housing part, a second housing part detachably connectable to the first housing part, a linear guide fixedly positioned within the first housing part, a piston rod linearly guided and rotationally secured by the linear guide such that it can be displaced for an emptying movement, an actuatable drive element for the piston rod, a coupling element including a coupling input element that couples the drive element to the piston rod in a coupling engagement, transmits a driving force of the drive element to the piston rod, and triggers the emptying movement, and a decoupling element comprising a sleeve part displaceably connected to the second housing part and coupled to the first housing part such that it is displaced by a movement of the housing parts in relation to each other into a decoupling position wherein the piston rod is decoupled from the coupling input element.
