  • Patent number: 9022258
    Abstract: A container (10, 30, 50) is provided for single- or multi-component molding materials. The container has a container body (12, 32, 52) having a constant outer contour in a longitudinal extent of the container (10, 30, 50), a piston (17, 37) movable in the longitudinal direction, and a cover (11, 31) having an outlet opening (13, 33, 53). A volume for a molding material is defined between the piston (17, 37) and the cover (11, 31), the volume being variable in the direction of the longitudinal extent of the container (10, 30, 50). The container distinguishes itself in that the container body (12, 32, 52) is rotatable relative to the outlet opening (13, 33, 53), and the piston (17, 37) thereby pushes out the content of the container (10, 30, 50).
