A synthetic resin bottle, protected from damage to the outer appearance under freezing conditions, and is effective in storage and transportation. The bottle is used by filling the bottle with contents have water as a main component and freezing such contents. The bottle comprises a body that has an out-of-round circular shape in the plane cross section over a certain height of the body, and the body wall has no hollowed portion caved inward. The body gradually narrows in the middle part except for the portions consisting of crests which are disposed at 3 or more points of the same central angle on the periphery of the plane cross section. In the middle part, the plane cross section is in the shape obtained by connecting the crests to one another with 3 or more arcs that curve outward. Pillars are formed vertically on the body by the crests.
