摘要
A device for dispensing extrudable material, including a reservoir containing the extrudable material and having a dispensing orifice, a tubular endpiece communicating, in an in-use position, with the orifice of the reservoir, and being separable from the reservoir, a base including a reciprocally displaceable piston, a plate-forming element at the front end of the base and having a passage for receiving the endpiece, and a space for receiving the reservoir between the plate-forming element and the piston. A sealing piece having an orifice is disposed between the plate-forming element and the reservoir, the sealing piece having a sealing face facing towards the reservoir and shaped for receipt within the orifice. The tubular endpiece extends through the orifice of the sealing piece, and beyond the sealing piece at a proximal end. The sealing piece and the reservoir are constructed and arranged to mate with substantially friction-free thrust contact along a line of travel of the reservoir displaced towards the plate-forming element in response to the piston, to establish a sealed connection between the sealing piece and the reservoir and permit dispensing of the extrudable material through the orifice and the tubular endpiece; and to separate from each other under the effect of the reservoir being displaced away from the plate-forming element.
