Patent ID: 7699816

Claim:
A device for administering metered doses of an injectable product, comprising: a) a housing incorporating a reservoir for the product, b) at least one drive member with a plunger which forces product out of the reservoir through an outlet when moved in a forward direction, c) a drive button which, when displaced, moves the drive member relative to the housing, and d) at least one delaying member moveable from a first position into a second position at a distance apart from the first position by displacing the drive button relative to the drive member in the longitudinal direction of the device, wherein the first position and the second position of the delaying member are defined by a guide profile in the form of a guide track recessed into the delaying member or the external face of the drive member and having a first recess for the first position of the delaying member and a second recess for the second position of the delaying member, whereby the drive member remains stationary relative to the housing during movement of the delaying member from the first position into the second position and the at least one delaying member establishes contact with the drive member in the first or second position so that when the drive button is displaced, the drive member is moveable in the forward direction before or after the at least one delaying member is moved relative to the drive member.
