Patent ID: 8267279

Claim:
A device for dispensing a dosage material, comprising: a dosage-dispensing unit comprising a delivery orifice with a closure element and a closure spring arranged therein, an aperture cross-section of the delivery orifice being variable from a closed position to a maximally open position due to the shape of the closure element and the linear mobility in the delivery orifice of the closure element along a central longitudinal axis thereof; a receiving device for the dosage-dispensing unit; and a drive unit comprising a drive shaft which, in an operating state of the dosage-dispensing device, linearly advances towards the dosage-dispensing unit for a clutch engagement of the drive shaft with the closure element and the opening of the delivery orifice, the drive shaft having limited linear mobility relative to the drive unit in a direction away from the dosage-dispensing unit to prevent a premature opening of the delivery orifice during the clutch engagement; wherein the closure spring holds the closure element in the closed position up to the point where the clutch engagement is completed.
