ABSTRACT:
A slender synthetic resin heat-resistant bottle type container having a circumferential draw ratio of 2.8 or less, for example, comprises at least one pressure reduction absorbing panel (5) provided at a container body part, wherein the pressure reduction absorbing panel is provided with at least one convex portion (6) having a width larger at a lower side than at an upper side as viewed in a circumferential direction of the container. Alternatively, each pressure reduction absorbing panel has a border line bulged toward a container bottom part. This causes a resin to be smoothly stretched even at mold surface portions corresponding to concave and convex portions of a container body part surface upon blow molding. These avoid a defective appearance of the container and do not adversely affect heat resistance thereof.
