Claim:
A blow-molded synthetic resin bottle, comprising: a shoulder; a bottom; a body located between the shoulder and the bottom; and at least one line of turn formed on the shoulder, the body, and the bottom along an entire vertical circumference of the bottle, and dividing the bottle into sections, the sections including: at least one shell section located on one side of the line of turn, the shell section having a relatively high rigidity; at least one reversible section located on another side of the line of turn, the reversible section having a relatively low rigidity such that the reversible section is deformable by resilient reversion; and a neck disposed only on a portion of the shoulder that is located on the one side of the line of turn in which the shell section is located, wherein the reversible section may be easily deformed from an original shape to a concave shape that may be received by the shell section and then restored back to the original shape by the resilient reversion, wherein the bottle is molded from a relatively soft synthetic resin so as to have a thin wall, and wherein a majority of at least one of an inner surface and an outer surface of the shell section is substantially laminated with another layer.
