Abstract
A dosage-dispensing device includes a drive device and a source container that can be set into the drive device, wherein a dosage-dispensing head is connected to a closure shaft which is movably constrained in the source container. The closure shaft has a coupler part configured to be coupled to and uncoupled from a drive shaft of the drive device. The source container has a first form element which is designed for form-fitting engagement with a first counterpart element formed on the drive device and serves to precisely position the coupler part in relation to the drive shaft. The source container further has a second form element which is designed for form-fitting engagement with a second counterpart element formed on the drive device and which, when in operating position, serves to precisely position the dosage-dispensing head in relation to a target container.
