Abstract
A blow-molded synthetic resin bottle that can be fully flattened and easily restored to an original shape. The bottle includes at least a line of turn is formed on the shoulder, the body, and the bottom along the entire vertical circumference. Among the sections divided by this line of turn, at least a section is used as a shell section in which at least a nearly entire body portion of this section has relatively high rigidity. The other section is a reversible section in which at least a nearly entire body portion has relatively low rigidity and is capable of being deformed by resilient reversion. The neck is disposed on the shoulder, and the reversible section can be deformed and easily concaved into the shell section for volume reduction and then can be restored to the original shape.
