Abstract: An apparatus for dispensing viscous, putty-like materials directly from a cylindrical, factory-filled can is used in conjunction with a can having one end and a hole formed in the other. A support shelf holds the can in place, the support shelf having an aperture in alignment with the hole formed in the can to allow the material therein to flow therethrough. A circular ram plate conforming in peripheral size and shape to the interior of the can is inserted into the can opening to pressurize the contents. In the preferred embodiment, a cutting knife is moved from side to side beneath the shelf to control the flow of the material from the can.
