Abstract
Apparatus for dispensing high viscosity thermoplastic materials such as resins, sealants and hot melt adhesives from drums. The apparatus comprises a functional hollow cylinder vertically disposed with a screw extending through its length. The cylinder is attached to a movable platen which is positioned to enter the open container through the top and adapted to move downward to the container bottom. Heating means, for example, a serpentine heated coil is attached to the underside of the platen. In operation, the thermoplastic material in the container is melted or highly softened enabling the screw to 'lift' the material in the upright cylinder to an opening or outlet provided in the upper portion of the cylinder.
