A device for the measured or dosed dispensing of a putty-like or paste-like multi-component substance stored in separate containers includes a housing for holding the containers with a separate piston and piston rod unit for each container mounted in the housing. To prevent displacement of the piston-piston rod unit in the direction opposite to the dispensing direction, each piston rod is provided with a stop member. By pressing a hand lever pivotally mounted in the housing, a drive device connected to the lever grips the piston-piston rod units and moves them in the dispensing direction. The stop member permits movement in the dispensing direction but prevents the movement of the piston rod in the opposite direction when the hand lever-drive device is released. When the containers are to be replaced, a releasing member, located on the housing, releases the stop members from holding engagement with the piston rods so that the piston-piston rod units can be withdrawn from the containers in the direction opposite to the dispensing direction. |
