<p><P>PROBLEM TO BE SOLVED: To provide a method for manufacturing a plastic bottle that can be extended or shrunk in a vertical direction where its vertical width (height) can be substantially reduced as compared with the case in which the stored content is charged in the main body of the plastic bottle. <P>SOLUTION: This plastic bottle main body is made of a flexible resin material such as a plastic resin, and its upper end has a drinking port and its side surface circumference part is formed into a bellows shape in either a horizontal direction or a slant direction. A vertical shape in the section of each of the pleats forming the bellows shows a substantial straight shape at its upper surface and a downward curved shape at its lower surface. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
