  • Hand holdable manually dispensing mastic container
    Patent number: 6003730
    Abstract: A hand holdable manually dispensing mastic container is made from two sheets of transparent plastics material which are welded together at a seam around the periphery thereof. The container is formed to have a dispensing edge and a filling end which are parallel to one another. The container has a generally elongate shape which diverges from the dispensing edge to a widest dimension, and parallel to the dispensing edge, and then converges to the filling end. Thus, two trapezoidal portions are formed. The volume of the portion closest to dispensing edge is smaller than the volume of the portion closest to the filling end.
