Abstract
This invention relates to process for preparing saturated polyester resin bottles, that the residual strain of the bottles is reduced and the deforming temperature is elevated. The process is that a heated intermediate material (1) made of a saturated polyester resin is set in a mold (5), then compressed air is blown in the intermediate material (1) to orient the same biaxially, temperature in thus shaped bottle is elevated to a temperature higher than the heating temperature of the intermediate material (1) under the elevated pressure to effect thermal fixing and thereafter the saturated polyester resin bottle (19) is taken out.
