ABSTRACT:
A biaxially oriented molded bottle of a saturated polyester, especially polyethylene terephthalate, exhibits various superior characteristics as a bottle container but, because of its lack of mechanical strength, its use as a pressure bottle has been regarded as impossible. According to the invention, the lack of mechanical strength is compensated for by slightly increasing the wall thickness of the bottle, and providing a bottom structure having a plurality of legs designed to counteract the deformation caused by the internal pressure.
