Administering apparatus with a resettable activating block
First Claim
1. An administering apparatus for administering a substance in selected doses, said administering apparatus comprising:
- a casing with a reservoir for the substance;
conveying means for delivering a selected dose of the substance from the reservoir;
dosing and activating means for performing a dosing movement for selecting a dose in a dosage selection position and for performing a delivery movement in an activating direction as far as a front end position for delivering the selected dose, said dosing and activating means coupled to the conveying means such that the delivery movement causes the selected dose to be delivered;
a dose indicator sleeve coupled to the dosing and activating means such that the dose indicator sleeve is moved by the dosing movement of the dosing and activating means to indicate a selected dose; and
a blocking member movable into and out of blocking engagement with the dosing and activating means in the front end position, wherein, when in blocking engagement, the blocking member prevents the dosing and activating means from moving counter to the activating direction, and wherein a reset cam protrudes from the dose indicator sleeve, via which the dose indicator sleeve moves the blocking member out of blocking engagement when the dose indicator sleeve is moved to a zero-dose position.

Abstract
An administering apparatus for administering an injectable substance in doses, wherein the apparatus includes a casing with a reservoir for the substance, a conveying mechanism which acts to deliver a selected dose of the substance from the reservoir, a dosing and activating mechanism which performs a dosing movement for selecting the dose in a dose selection position and a delivery movement in an activating direction as far as a front end position for delivering the selected dose, and which is coupled to the conveying mechanism such that the delivery movement causes the selected dose to be delivered, a dosage indicator sleeve coupled to the dosing and activating mechanism such that the dosage indicator sleeve is moved relative to the casing by the dosing movement of the dosing and activating mechanism to indicate the selected dose, and a blocking member in a blocking engagement with the dosing and activating mechanism in the front end position to prevent the dosing and activating mechanism from moving counter to the activating direction, wherein the blocking member can be moved out of the blocking engagement against an elasticity force and 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.

3. 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; and
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. - View Dependent Claims (4, 5, 6, 7, 8, 9, 10, 12, 13, 14, 15, 16, 17, 18, 19)
