Administering device with blockable actuation element

1. An apparatus for administering a substance, comprising a housing, an administering mechanism accommodated in the housing, an actuation element for actuating the administering mechanism, a receptacle for holding the substance, wherein the receptacle is rotatable relative to the housing and receives a two-chamber carpule, each chamber containing a constituent of the substance, the constituents being able to be mixed by rotation of the receptacle, and a lock for releasably locking the actuation element, wherein the lock can be unlocked by rotating the receptacle.

2. The apparatus for administering a substance according to claim 1 , wherein the receptacle comprises an abutment and the lock comprises a counter-abutment, the abutment and counter-abutment interacting to move the lock from locked to unlocked.

3. A device for administering a fluid product, comprising:

a housing for receiving an administering mechanism,

an actuation element for actuating the administering mechanism,

a receptacle for receiving the fluid product, wherein the receptacle is rotatable releative to the housing and receives a two-chamber carpule, each chamber containing a constituent of the fluid product, the constituents being able to be mixed by rotation of the receptacle, and

a blocking mechanism for blocking the actuation element,

wherein

the blocking mechanism is movable from a blocking position to a release position by rotation of the receptacle.

4. The device for administering a fluid product as claimed in claim 3 , wherein the receptacle has an abutment and the blocking mechanism has a counter-abutment, which interact to move the blocking mechanism from the blocking position to the release position.

5. The device for administering a fluid product as claimed in claim 3 , wherein, in the release position of the blocking mechanism, the actuation element is movable relative to the housing along a longitudinal axis of the housing.

6. The device for administering a fluid product as claimed in claim 3 , wherein the blocking mechanism is on the actuation element.

7. The device for administering a fluid product as claimed in claim 6 , wherein the blocking mechanism comprises a flexible arm which can deflect relative to the actuation element in the circumferential direction of the longitudinal axis.

8. The device for administering a fluid product as claimed in claim 3 , wherein the blocking mechanism is rotatable relative to the actuation element.

9. The device for administering a fluid product as claimed in claim 8 , wherein the blocking mechanism has a blocking abutment which, in the blocking position, abuts against a longitudinal abutment on one of the actuation element, the housing, or a structure fixed to the housing.

10. The device for administering a fluid product as claimed in claim 9 , wherein the blocking mechanism comprises a locking means for, in the blocking position, locking a drive member against forward movement.

11. The device for administering a fluid product as claimed in claim 3 , wherein the release position of the blocking mechanism corresponds to a position of the two-chamber carpule after mixing has taken place.

12. A device for administering a fluid product, comprising:

a housing for receiving an administering mechanism;

an actuation element for actuating the administering mechanism;

a receptacle for receiving the fluid product;

a blocking mechanism for blocking the actuation element, wherein the receptacle is rotatable relative to the housing and the blocking mechanism is movable from a blocking position to a release position by rotation of the receptacle; and a catch mechanism which locks the receptacle relative to the housing in the release position of the blocking mechanism.

13. The device for administering a fluid product as claimed in claim 12 , wherein the receptacle receives a two-chamber carpule, each chamber containing a constituent of the fluid product, the constituents being able to be mixed by rotation of the receptacle.
