Application date: August 10, 2004 certification date: Approval Announcement No.: Approval announcement date: July 13, 2005 description 7. CD no. of operation manual: d0528 main classification No.: b65d21/08 classification No.: b65d21/08; B65D1/02; B29D22/00;//B29k67:0 forming temperature: 330 ⑶ 80 ℃ 0 division original application No. priority item 2003.12.30 us 10/747132 abstract the invention relates to a longitudinally retractable polyester bottle and its manufacturing method and device. It provides a polyester bottle whose longitudinal width (height) is substantially reduced during the manufacturing of the container body compared with the filling of the container body. In addition to the mouth of the upper end, the container body which has a serpentine belly shape in the longitudinal width and longitudinal direction partially or completely becomes horizontal is formed in a state of substantially lower volume and height than that when the contents are filled. At the same time, when a blank part is obtained in the container body by drinking the contents, the volume and height when the contents are filled can be obtained again Lower state molding with highly substantial volume reduction. Claim 1. A longitudinally retractable polyester bottle, which is characterized in that, in addition to the mouth at the upper end, it is provided with a container body which longitudinally includes the source of synthetic monomers and has wide biodegradability. Part or all of the container body longitudinally becomes a serpentine shape in the horizontal direction. The container body is formed in a lower height than the volume when the contents are filled and the volume is substantially reduced in the manufacturing process, At the same time, when the blank part is obtained in the container body by drinking up the contents, the volume and height of the test piece can be obtained again, which is higher than that when the contents are filled. (3) the test piece can be placed at the center of the spherical support plate of the movable table of the experimental machine to substantially reduce the volume.
