ABSTRACT:
The present invention consists of an improvement device for the squeezing of tubes containing paste, in particular toothpaste. The device in question consists of a tubular casing which can be affixed to the wall, inside which slides a piston fitted with a suitably shaped slit, into which the closed end of the tube containing the paste is inserted. The open end of the tube rests on the base of the said casing and the paste flows out through a hole present on the same base. The piston is pushed forwards by a threaded rod topped by a knob. As the piston slides, the sides of the slit produce, thanks to their particular shape, pressure on the tube which forces out the paste.
