Abstract

PURPOSE: Grooves or small holes are provided on the outer surface of the top insert or on the bottom of the gasket to exclude the remaining air by the self-sealing action, thereby preventing the degradation of polymers in the pack.
CONSTITUTION: The seal ring 8 is radially grooved on the bottom surface to form grooves 10. When the inner pressure becomes higher by the introduction of the melted polymer, the remaining air is led through grooves 10 to be space 12 between the top cap 9 and the tip insert 7 according to the pressure. The rise in the inner pressure starts the self-sealing action to press the seal ring 8 and the air is substantially expelled and replaced with the melted polymer before the grooves are deformed by the inner pressure and sealed.
