摘要:
A fuel cell cartridge for containing fuel for fuel cells, comprising a polyester resin, wherein after the fuel is contained and preserved at 60° C. for one week, a change of density at the bottom portion and the mouth portion is 0.01 g/cm3 or less. Even when methanol of a high concentration is contained, the fuel cell cartridge maintains excellent appearance effectively preventing the occurrence of whitening in the container and, particularly, at the mouth portion and the bottom portion thereof, and effectively suppressing a decrease in the shock resistance.

摘要:
A polyester container obtained by stretch-forming a preform of a thermoplastic polyester resin formed by injection forming wherein the central portion of the bottom wall is the remaining part of the gate at the time of injection forming, and is formed relatively thicker than the bottom wall surrounding the central portion, and the central portion of the bottom wall is substantially amorphous, and the bottom wall surrounding the central portion is oriented and crystallized. The container exhibits excellent heat resistance and shock resistance despite a thick portion that is the remaining portion of the injection gate is formed at the center of the bottom portion.
