Claim:
An administering apparatus for administering an injectable product in doses, said administering apparatus comprising: a) a casing with a reservoir for the product; b) a conveying means which acts on the product in order to deliver a selected product dosage from the reservoir; c) a dosing and activating means which performs a dosing movement for selecting the product dosage in a dosage selection position and performs a delivery movement in an activating direction as far as a front end position, for delivering the selected product dosage, and which is coupled to the conveying means such that the delivery movement causes the selected product dosage to be delivered; d) a dosage indicator sleeve which is coupled to the dosing and activating means such that the dosage indicator sleeve is moved relative to the casing by the dosing movement of the dosing and activating means, in order to indicate the selected product dosage; and e) a blocking member which is in a blocking engagement with the dosing and activating means in the front end position of the dosing and activating means to prevent the dosing and activating means from moving counter to the activating direction; f) wherein the blocking member can be moved out of the blocking engagement against an elasticity force; g) wherein a reset cam protrudes from the dosage indicator sleeve, via which the dosage indicator sleeve presses the blocking member out of the blocking engagement, when the dosage indicator sleeve is moved to a zero-dosage position relative to the casing; and h) wherein a counter reset cam protrudes from the blocking member, and wherein the reset cam presses against the counter reset cam in the zero-dosage position of the dosage indicator sleeve.
