摘要： A bottle molded from a polyester composition comprising 97 to 99.99% by weight of a polyester and 3 to 0.01% by weight of a polyester elastomer, which bottle exhibits dimensional change ratios of not greater than 5% measured in the height direction of the bottle and also not greater than 5% measured in the wall part diameter direction of the bottle and has an overturning angle of at least 10.degree., when the bottle was subjected to a hot bath test in which the bottle is filled with a beverage containing 2.5 gas volume carbon dioxide at 23.degree. C., stoppered and immersed in sealed condition in a hot bath heated at 70.degree. C. Thus, the bottle retains self-standing property without deformation even after it is filled with a carbonated beverage and subjected to heat sterilization.
