ABSTRACT:
A dispenser particularly useful for dispensing toothpaste includes a tubular body closed at one end and having an opening for receiving the neck portion of a toothpaste tube extending therefrom, the dispenser includes an arrangement for squeezing the contents of the tube out the discharge opening including a piston movable in an axial direction of the tubular body. The arrangement includes the piston having a pair of oppositely extending projections that extend through parallel extending slots in the tubular body and are engaged in an internal threaded track of a sleeve received on the tubular body so that rotation of the sleeve will cause the piston to move along the slots and squeeze the contents of the tube towards the discharge opening of the tube.
