The present invention relates to a device for producing a hardenable mass, preferably bone substitute and/or bone reinforcing material or bone cement or similar material. A mixing container ( 3 ) has a mixing space ( 4 ) in which at least one powder and at least one liquid component ( 5, 6 ) are mixed to provide the hardenable mass ( 2 ). A piston means ( 7 ) is provided in the mixing space ( 4 ) of the mixing container ( 3 ). At least one means ( 8 ) which is rotatable relative to the mixing container ( 3 ) cooperates with the piston means ( 7 ) for, in a retaining position (P 1 ), retaining said piston means ( 7 ) relative to the mixing container ( 3 ) and, by rotation to a release position (P 2 ), releasing the piston means ( 7 ) such that said piston means can move in a direction (U) towards at least one opening ( 49 ) through which said mass ( 2 ) can pass out of the mixing space ( 4 ). The rotatable means ( 8 ) is provided such that it in its release position (P 2 ) can follow the piston means ( 7 ) in the mixing space ( 4 ) in the direction (U) towards said opening ( 49 ). |
