Claims

[Scope of claims for utility model registration] (1) In a vacuum-resistant biaxially stretched blow-molded container,
Having ribs extending vertically on the same plane as the body on opposing side surfaces of the body of the container,
Each of the pair of ribs has a decompression deformation part, and the decompression deformation part consists of a peripheral part that is recessed one step from the surrounding body surface and a central part that is slightly curved outward, and 1. A vacuum-resistant biaxially stretched blow-molded container, characterized in that when the pressure inside the container is reduced, the central portion is recessed to absorb the vacuum. (2) In the decompression-resistant biaxially stretched blow-molded container according to claim 1, the decompression deformation section is provided below the container body, and above the container body, a pair of first and second holes are provided on opposing side surfaces. Two decompression deformation parts are provided, and the second decompression deformation part has an upper part that is continuous with the body surface and is slightly curved outward, and an arc-shaped part that is concave one step from the body surface. 1. A vacuum-resistant biaxially stretched blow-molded container, characterized in that the vacuum deformation portion and the second vacuum deformation portion are recessed by vacuum.
