The invention relates to devices for squeezing out free-flowing compositions which only release the flow of at least one constituent when squeezing-out pressure is exerted on them. Said inventive devices contain at least one cylindrical container (1) for accommodating the free-flowing constituents (2). Said cylindrical container (1) can be closed by means of two pistons (2, 4) which move axially, and has a material outlet opening (5) at the lower end of the cylinder wall. Said material outlet opening (5) only releases the flow of the free-flowing constituents (2) after the lower piston (4) has been moved over the material outlet opening (5), past said opening into the end position (4') by the squeezing-out pressure. According to a preferred configuration, the inventive device has at least one cylindrical container of the aforementioned type, and is suitable for squeezing out two or more free- flowing constituents spatially separately or synchronously. © KIPO & WIPO 2007 ...
