    摘要： A syringe (1) for dispensing a multi-component material comprises: a syringe cartridge (3) having a first end and a second end, and respective compartments (5, 7) for components of the multi-component material; a static mixer (9) connected to the first end of the cartridge, the mixer having a dispensing outlet (11); and a plunger assembly (13) that is movable into the syringe cartridge at the second end to dispense material from the first end. The connection (21) between the static mixer (9) and the first end of the syringe cartridge (3) comprises a flow-directing mechanism having a venting position in which the cartridge compartments (5, 7) are cut off from the static mixer and are in communication independently with respective venting outlets, and a dispensing position in which the cartridge compartments are in communication with the static mixer and are cut off from the venting outlets. The syringe cartridge (3) is formed, at one end, with entry ports (16, 18) through which components of the multi-component material can be loaded into the compartments from a supply cartridge (40, Fig. 5). The entry ports (16, 18) have upstanding collars (49, 51, Fig. 5) for sealing to respective outlets (47, Fig. 5) of the supply cartridge (40), at least a portion of each upstanding collar being formed to be located inside the respective outlet of the supply cartridge, whereby material is removed from within the outlets when the syringe is removed from the supply cartridge.
