    摘要: The present invention relates to a saturated polyester resin bottle made thin by biaxial orientation and comprising a trunk portion formed to have a regular polygonal cross section consisting of a plurality of generally upright flat sides separated by vertically oriented ribs. When the interior of the bottle is subjected to a vacuum, the flat sides uniformly warp radially inwardly to accommodate the vacuum without detracting from the appearance of the bottle.
