PROBLEM TO BE SOLVED: To provide a heat filling bottle having a decompression absorption function and a squeezing function simultaneously.SOLUTION: In the heat resistant direct blow-molded heat filling bottle, a first peripheral wall (7) is provided around a body part (4). The peripheral wall (7) includes an upper edge part (7a) and a lower edge part (7b) which are disposed at any height positions of the body part (4) to oppose to each other vertically and a first groove bottom (7c) disposed at a position on the back side between the upper edge part (7a) and the lower edge part (7b), and is formed to have a recessed cross-section. Due to elastic deformation of the first peripheral groove (7), an opposing clearance between the upper edge part (7a) and the lower edge part (7b) becomes narrower than a groove width of the first groove bottom (7c). |
