Claims

[Scope of claims for utility model registration] (1) In a vacuum-resistant biaxially stretched blow-molded container,
The body has a shape consisting of three regions, an upper part, a central part, and a lower part, and has a square chamfered part, and in the upper part, the chamfered part is curved into a spherical shape and is continuous with the adjacent chamfered part, and the said continuous part is A first decompression deformation part is provided at the lower part of the side part existing between the chamfered parts, and a second decompression deformation part is provided at the side part of the central part, and each of the decompression deformation parts extends from the peripheral part. It has a peripheral part that is concave one step and a central part that is slightly curved outward, and the curved central part is concave due to the reduced pressure inside the container, thereby being able to absorb reduced pressure. Decompression biaxially stretched blow-molded container. (2) The vacuum-resistant biaxially stretched blow-molded container according to claim 1, further comprising vertically extending grooves in the upper and lower parts of the side surfaces on both sides of the continuous chamfered part, respectively. 1. A vacuum-resistant biaxially stretched blow-molded container, characterized in that it has an arcuate groove at the upper end of a side surface, and a continuous groove at the ends of both grooves.
