PROBLEM TO BE SOLVED: To provide a container for cut tofu in which the container is hard to cause a large difference in deformation resistance when a side pressure is applied to one of opposite two pairs of side wall part and when the side pressure is applied to the other, and a relatively high distortion resistance can be exhibited even when the side pressure is applied to any direction.SOLUTION: A container 1 for cut tofu is thermoformed of a thermoplastic resin sheet, and has a bottom wall 11 with an outer circumferential edge being rectangular in a plan view, rectangular frame-like peripheral side walls 12 rising up from the outer circumferential edge, and a flange 20 extending outward from the top part of the peripheral side wall. The bottom wall is formed of orthogonal ribs extending inward from each of four sides of the outer circumferential edge and extending along a substantially perpendicular direction to the circumferential direction of the outer circumferential edge. The orthogonal ribs are formed by several ribs at intervals in the circumferential direction at each side of four sides. The bottom wall is further provided with skew ribs extended along the direction from the corner of the outer circumferential edge to the central part of the bottom wall, and extended to the skewed direction to the four sides. |
