<P>PROBLEM TO BE SOLVED: To decrease an opening force and improve productivity, concerning a liquid storage container having a liquid supply port sealed with a cap. <P>SOLUTION: The cap 7 for sealing the liquid supply port of the liquid storage container has a rib 13 for bonding the liquid storage container with the cap 7. The rib 13 is arranged at a position opposite to the liquid supply port and an area of a mount 14 of each rib 13 is equalized to each other. The section modulus of the mount 14 is different from each other on a surface perpendicular to the direction of force applied to the mount 14, when the rib 13 is debonded from a liquid storage unit. <P>COPYRIGHT: (C)2012,JPO&INPIT |
