Abstract: <P>PROBLEM TO BE SOLVED: To provide a package body of an ink package in which the ink package can be prevented from being deformed by a pressure-tight structure made of paper while suppressing degradation in the degree of deaeration of ink.  <P>SOLUTION: Since a corrugated fiberboard sheet constituting a pressure-tight structure 20 has a wide surface intersecting the wide surface of an ink package 2 perpendicularly, the wide surface of the corrugated fiberboard sheet constituting the pressure-tight structure 20 can resist more against atmospheric pressure acting through a packing bag 4 as compared with a case where the wide surface of the corrugated fiberboard sheet is in parallel with the wide surface of the ink package 2. Consequently, the ink package 2 can be prevented from being deformed even when the interior of the packing bag 4 is reduced in pressure as usual. Since the interior of the packing bag 4 can be brought into further pressure reduced state as compared with a conventional case, air in the packing bag 4 is decreased furthermore. Consequently, the air remaining in the packing bag 4 can be prevented from permeating the ink package 2 and dissolving into ink to degrade the degree of deaeration of ink.  <P>COPYRIGHT: (C)2004,JPO
