ABSTRACT:
A dispensing container for dispensing molten plastic into a mold, the container being piston operated and having a heater inside the container for minimizing the time required to melt solid plastic. The heater extends axially of the container while passing in sealing engagement with the piston which therefore slides upon the heater during its movement. The heater is preferably mounted at one end about a universal mounting from which the heater freely extends. This mounting allows for slight movement of the heater laterally if misalignment with the piston occurs.
