Abstract
A dispensing container for a viscous substance comprising a sleeve defining an axis of rotation and having a pair of ends arranged at first and second locations along the axis, the sleeve further defining a helical travel path on an inward facing surface thereof. A dispensing member mounted in association with one of the pair of ends of the sleeve, and, a piston head mounted within the sleeve and defining an outward facing peripheral surface operative to cooperate with the helical travel path and further defining with the dispensing member and a portion of the sleeve extending therebetween a storage volume for the viscous substance. The piston head travels along the axis of rotation when undergoing rotation thereabout relative to the sleeve, a linkage apparatus is integrally formed with the piston head and defining an end portion associated with a predetermined portion of the sleeve. The linkage apparatus permits axial displacement of the piston head relative to the predetermined portion proportional to the distance between the predetermined portion and the dispensing member, and an apparatus is provided for engaging the end portion of the linkage apparatus and thereby preventing simultaneous rotation of the piston head and the sleeve in the same direction to facilitate axial displacement of the piston head.
