Abstract:
A device for dispensing a spreadable material comprising a tubular holding element having a dispensing end and a tube base at an end opposite the dispensing, end, in which the tubular holding element is arranged an internally screwthreaded, non-rotatable piston element that carries the spreadable material and that is displaceable longitudinally from the tube ease of the tubular holding element to the dispensing end by an externally operated control wheel provided at the tube base end of the tubular holding element, the control wheel comprising an axially supported externally screwthreaded spindle that extends rotatably through an opening in the tube base into the tubular holding element and that co-operates with the internal screwthread of the piston element, so that when the piston element is drawn adjacent to the tube base, the spindle is able to slip relative to the piston element if the spindle is rotated any further, wherein the screwthread-free region of the spindle has a smaller length than the internal screwthread of the piston element.
