<p><P>PROBLEM TO BE SOLVED: To prevent a folded bellows-like barrel part from being unexpectedly expanded, and to simply affix a label or the like to an outer surface of the bellows-like barrel part with the volume thereof expanded. <P>SOLUTION: A bellows plastic bottle 1 comprises a bellows-like barrel part 4 which is expandable in the axial direction, a bottom part 5, a shoulder part 3, and a mouth part 2. The bellows-like barrel part 4 comprises a plurality of ridge parts 9a and valley parts 9b which are formed by alternately and continuously providing one truncated conical part 8a and the other truncated conical part 8b with their axial directions opposite to each other. The ridge parts 9a and the valley parts 9b are bendable, and the width of one truncated conical part 8a is set to be larger than the width of the other truncated conical part 8b. A fitting recessed part 7 is recessed in the outer circumferential surface of a cylindrical part 5a of the bottom part 5, and a flanged part 6 is protruded from an outer circumferential surface of the mouth part 2. <P>COPYRIGHT: (C)2004,JPO</p> |
