SYNTHETIC RESIN BOTTLE

摘要

A synthetic resin bottle including a trunk having a bottom, wherein the trunk is divided by a constriction into an upper trunk and a lower trunk. The bottle is easily portable and operable without requiring an additional handle etc. and has high buckling strength. The bottle (1) has the dome-shaped upper trunk (4) connected, with the constriction (3) in between, to the lower trunk (2) having the bottom, a shoulder (5) surrounding the upper end of the upper trunk (4), and a tubular section (6) connected to the shoulder (5). Two depressions (4a) facing each other are arranged on the rear side of the upper trunk (4) along its circumferential direction. A portion formed between the depressions functions as a grip (G), and vertical ribs (4r) are each provided on a step surface (f1) formed on the front side of each depression (4a).
