Abstract:
1. A device for administering a fluid product comprising a housing, a conveying device for the product, a coupling element provided for the drive of the conveying device and which can be rotated about a rotational axis, a first blocking member connected in a rotationally secure manner to the coupling element, a second blocking member detachably engageable with the first blocking member thereby preventing a rotational movement thereof in the drive direction and enabling said rotational movement to take place in the counter dosing direction, a torsion spring connected to the coupling element such that it is stressed by the rotational movement when the blocking members are engaged in a blocked position and drives the coupling element in a rotary manner after the blocking position is released, and a release element coupled to at least one of the blocking members such that a release movement of the release element translationally along the rotational axis displaces at least one of the blocking members from the blocked position, the release element also forming a dose setting element used to set a product dose amount to be delivered.
