发明名称 Device for expelling a paste contained in a tube.
摘要 The present invention relates to squeezer device for tubes containing fluid paste, in particular toothpaste. A piston (3), equipped with an expressly contoured slot (7) in which the rear part (8) of a tube (9) containing the fluid paste is inserted, can slide in a tubular casing which may be fastened to the wall. This tube bears via its front part (10) on the base (2) of this casing and emerges via its end (11) through a hole in the said base, whilst this piston is pushed forward by an appropriate means, such as a screw press (4) or a system composed of a manually or electrically controlled rack and pinion. The pressure exerted on the tube by the walls of the slot of the piston, as it advances, causes the expulsion of the paste. <IMAGE>
