Claims

[Scope of claims for utility model registration] (1) In a vacuum-resistant biaxially stretched blow-molded container,
The container has a horizontal rib extending to opposing side surfaces, and a V-shaped rib extending from approximately the center of the horizontal rib, the horizontal rib extending to a part of both adjacent side surfaces, and The V-shaped rib is continuous with the V-shaped rib on the opposite side surface to form a step part, and a first decompression deformation part is formed between the V-shaped rib and the horizontal rib and the V-shaped rib. A second decompression deformation portion is formed between the rib and the stepped portion, and each of the decompression deformation portions has a peripheral portion recessed one step from the periphery and a center curved slightly outward from the peripheral portion. 1. A vacuum-resistant biaxially stretched blow-molded container, characterized in that the curved central portion is concave due to vacuum in the container, thereby being able to absorb vacuum. (2) In the vacuum-resistant biaxially stretched blow-molded container according to claim 1, the first vacuum deformation portion and the second vacuum deformation portion are formed symmetrically at the upper and lower portions of the container body. The central part of the container body is provided with third decompression deformation parts at four side parts.
The third decompression deformation part consists of a peripheral part that is recessed one step from the central part surface and a central part that is slightly curved outward, and the first decompression deformation part and the second deformation part are formed by the depressurization inside the container. A vacuum-resistant biaxially stretched blow-molded container, characterized in that the vacuum deformation portion and the third vacuum deformation portion are recessed to absorb vacuum.
