<p><P>PROBLEM TO BE SOLVED: To create a side peripheral wall structure of a synthetic-resin square bottle, that can effectively obtain restorability which decreases due to the reduced thickness of the bottle, especially when the side peripheral wall is deformed so as to be bent by a load applied from a lateral direction. <P>SOLUTION: The synthetic-resin square bottle includes a body where the side peripheral wall is formed by four flat side walls and four chamfered corner walls coupling the side walls. A vertical-groove-like vertical rib is arranged along an edged line formed in a border of the side wall and the corner wall. Further, in an area of the vertical rib at a predetermined height, a plurality of vertical-groove-like vertical auxiliary ribs are arranged along the vertical rib so that they laterally align. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
