LINER FOR PRESSURE VESSEL, MOLDING TOOL THEREFOR, AND PRESSURE CONTAINER

摘要

PROBLEM TO BE SOLVED: To provide a technique for suppressing the occurrence of a weld in a liner for a pressure vessel.SOLUTION: A film gate 42 for molding a pressure container liner 1 is arranged on a radially outer side of the outer peripheral end of an engaging part 3 in the pressure container liner 1. The position of the film gate 42 is arranged at a sufficient spacing on the radially outer side of the engaging part 3 so that the flow velocity of a molten resin at a molding time can be controlled to suppress the occurrence of a weld.
