The two components are held in a cylindrical housing (1), separated by a partition wall (4) attached to a piston rod (10). The rod is screwed into the partition aperture with the screw action limitted by stops, while in one position a connection through the partion is opened via axial grooves. In operation, the control is screwed to open the connection. Reciprocal axial movement of the partition mixes the components. The connection is screwed shut, with the partition at the rear of the container, enabling the mixt. to be forced out through a nozzle (21), once the cap (22) is removed.
