Abstract
A device for dosed dispensing of flowable material components comprises supply containers receiving the material components and having an outlet and with at least one removal element having an inlet. Each material component can be removed from the supply container in dosed charges by a screw with controllable drive. The removal element can be docked to the outlet of the supply container, wherein the screw is disposed without drive, but rotatable in the region of the outlet and within the supply container and has an outlet-side coupling element. A controllable drive is disposed in the region of the inlet of the removal element whose drive shaft has a terminal coupling element which can be connected to the coupling element of the screw for secure mutual rotation therewith, and also having a closing piece sealing the outlet of the supply container. The closing piece for the outlet of the supply container is loaded with an axial spring force to hold the closing piece in sealing abutment on the outlet. The coupling element on the drive shaft is provided with an integrated suction gripper for lifting the closing piece from the outlet in opposition to the spring force.
