摘要

A method for sealing a bore formed in a cover film is disclosed. An ink inlet hole formed in an ink cartridge is covered at a hole covering area of the cover film. The method includes formation of a recess outside the hole covering area by removing a portion of the cover film, mounting a seal film on the cover film in such a manner that the seal film covers the bore, and sealing the bore with the seal film by heating the seal film with the seal film mounted on the cover film and thereby melting a side of the seal film opposed to the cover film.
