Patent ID: 7309327

Claim:
An administering apparatus for administering a fluid product in doses, the administering apparatus comprising: a) a casing comprising a reservoir for the product; b) a driven device for performing a delivery stroke in an advancing direction along a translational axis to deliver a product dosage; c) a drive device for performing a delivery movement to deliver the product dosage; d) a dosage setting member coupled to the driven device such that a rotational dosing movement performed by the dosage setting member and the driven device about the translational axis causes an axial translational dosing movement of the dosage setting member relative to the driven device and the casing; e) a translational stopper positioned opposite and axially facing the dosage setting member in an axial end position of the dosage setting member; and f) a rotational block which, in the end position of the dosage setting member, permits the rotational dosing movement in a first rotational direction and blocks the rotational dosing movement in a second rotational direction, wherein the rotational block comprises at least one first rotational stopper and at least one second rotational stopper, the first rotational stopper and the second rotational stopper abutting against one another in the end position of the dosage setting member, wherein the at least one first rotational stopper is secured against rotating, by the dosage setting member and the at least one second rotational stopper is secured against rotating, by the drive device.
