SEAL BONDING METHOD AND ITS BONDING STRUCTURE

摘要

PURPOSE: To miniaturize an apparatus performing the leak-resistant bonding of two members in the ink container of a thermal ink jet printer without using a bonding member. CONSTITUTION: A first frame member 22A equipped with an inner upright pipe 28 having an opening 30 allowing an ink container and a printing head to communicate with each other formed thereto is formed and a second frame member 22B is formed by injection molding so as to surround the inner upright pipe 28 and cooled and contracted to realize the hermetic seal bonding resistance between both members.
