PROBLEM TO BE SOLVED: To increase flexural rigidity along a direction parallel with an open/close hinge, and to prevent an unexpected contact and disruptive accident between adjacent eggs.SOLUTION: At a position deviated to an existing side of an intermediate partition post (10a) in a longitudinal partition wall (8a) partitioning an egg storage recessed part (9a) of a container body (A) in a grid state, a deflected groove (17) in a substantially u-shape is cut by a fixed depth (d5) in a depressed state. At an end part of a lateral side partition end post (14a) protruding upward from a portion where the longitudinal partition wall (8a) intersects orthogonally with both lateral side edging flanges (1a), an end groove (18) in a substantially u-shape in parallel with the deflected groove (17) is cut by a substantially same depth (d6) in a depressed state, and a portion of the lateral side partition end post (14a) is remained between the deflected groove (17) and the end groove (18). |
