The object of the invention is a cartridge (1) which is economical to manufacture and, also, to fill, only has a small amount of plastic and, when disposed of, causes a low level of pollution. In addition, it should be possible to use said cartridge in as many ways as possible, to empty out residues therein as far as possible, and to provide a great transportation volume. To this end, a cartridge (1) for flowable media is provided which has a volume-limiting envelope (2) made of flexible material. Said cartridge is provided at one end with a plunger-shaped press-out member (4) and at a second end with an outlet member (3). There is in the region of the outlet a dispensing opening the diameter of which, taking into account the forces which can be applied by the press-out member, the viscosity of the flowable medium and the flexibility of the envelope, ensures in the volume limited by the envelope an internal pressure which is suitable to counteract folding of the envelope material into the volume.

Methods and apparatus (100) are set forth for preparing and delivering bone cement from a powdered polymer component and a liquid monomer component by simultaneously injecting the powdered and liquid components, stored in separate component chambers (102, 103) into an evacuated mixing chamber (123) under the effect of the vacuum; by uniformly mxing the components in the mixing chamber (123) (to thoroughly wet the powder); and by delivering the cement formed by the polymerization process, as needed in an operative setting, utilizing a single ready to use device. The uniform mix is achieved by simultaneously subjecting the contents of the component chambers (102, 103) to the effects of the mixing chamber's (123) vacuum via separate one way nozzles (114, 115) interconnecting the component chambers (102, 103) to the mixing chamber (123), which cause the powder to be broadcast and liquid to be sprayed into the mixing chamber (123). The nozzles (114, 115) are designed and oriented in a predetermined manner (depending on the type and quantity of the constituent bone cement components being mixed), to cause the components to interact at a preselected distance within the mixing chamber (123), to assure uniform powder saturation and a thorough mix which yields a homogeneous reaction product.
