Abstract
Material Supply Equipment in which a cylindrical container constructed with a substantially straight side all the way to the bottom receives a plastic bag filled with a high viscosity fluid to be pumped. A planar cover plate for the container has an outer diameter closely fitting the inside surface of the container to press the plastic bag therebetween and has a central suction hole. A suction pump is provided having a planar suction plate which can be lowered onto the planar cover plate. The planar suction plate has a plurality of suction holes which register with the central hole of the cover plate encircled by an "O" ring groove and "O" ring to prevent dripping and infusion of air, respectively.
