Patent ID: 8048037

Claim:
A device for the administering of a fluid product, the device comprising: a housing; a delivery arrangement for delivering the product from a reservoir, wherein the delivery arrangement comprises a rotatable input member and a delivery element movable along a thrust axis, which delivery element is driven by a rotation of the input member; a drive arrangement coupled to the input member such that a rotation of the drive arrangement drives rotation of the input member about the thrust axis relative to the housing, wherein the drive arrangement is tensioned by a rotary tension movement; a rotatable dosing arrangement for setting a dose of the product, the rotatable dosing arrangement coupled to the drive arrangement such that rotation of the dosing arrangement tensions the drive arrangement; and a triggering arrangement movable from a position of rest into a triggering position to trigger an administering; wherein a first coupling is between the drive arrangement and the input member of the delivery arrangement, whereby the drive arrangement and the input member of the delivery arrangement are connected with each other to be locked against relative rotation in a coupled position and are detached from each other in an uncoupled position, wherein a second coupling is between the dosing arrangement and the drive arrangement, whereby the dosing arrangement and the drive arrangement are connected with each other to be locked against relative rotation in a coupled position and are detached from each other in an uncoupled position, and wherein in the position of rest of the triggering arrangement the first coupling assumes its uncoupled position and the second coupling assumes its coupled position, so that a rotation of the dosing arrangement is able to be transferred to the drive arrangement and not to the delivery arrangement, and a movement of the triggering arrangement from the position of rest into the triggering position firstly brings about a coupling of the first coupling and thereafter an uncoupling of the second coupling, so that the drive arrangement is released and the resulting drive movement is able to be transferred to the delivery arrangement.
