Abstract

A device for expressing free-flowing compositions is presented having a cylindrical container (1) for accommodating a free-flowing component (2), two axially displaceable pistons (3) and (4) designed to close the cylindrical container, and a material outlet opening (5) at the lower end of the cylinder wall. The material outlet opening only releases the flow of the component (2) after the piston (4) has been moved past the material outlet opening into the end position (4') by the expressing pressure. The device can be used with a conventional applicator for one-component adhesives, sealants or coating materials to provide the addition of a second component.
