ABSTRACT:
A transport and processing apparatus for a two-component material, in particular for bone cement, has a liquid component (1) and a powder component (2) which are separated by a membrane (3) and each occupy a transport chamber (4, 5) in a closeable container (6, 7) which has an expulsion piston (8) at one end and an opening (9) for the expulsion of mixed two-component material at the opposite end. The transport chamber (4) for the liquid component has a ring shape and a central aperture (34) for expelling the mixed two-component material through the aperture (34). The membrane is destroyed by a relative movement between the transport chamber for the liquid component (1) and a solid body (12, 17) enclosed in the container in order to effect a flow of the liquid component (1) into the transport chamber (5) for the powder component (2) and to enable the mixing with a mixing piston (11).
