PROBLEM TO BE SOLVED: To increase the rigidity of a flange of a subdivision tray with separating lines, improve the yield, productivity and working efficiency thereof, reducing the cost thereof and separating storage sections easily. SOLUTION: A plurality of storage sections 2 and connected together by flanges 3 of a subdivision tray 1, and separating lines 5 cut discontinuously into the wave forms are formed on the flange sections 3 of the subdivision tray 1, and the connecting sections 6 of the separating lines 5 are so formed as to position on both sides of centerlines running through the centers between respective crests and routes of the separating lines. The bending force applied to the subdivision tray 1 can be received not by the connecting sections 6 of the separating lines 5 but by the flange sections 3 by the arrangement to reduce the bending properties, improve yield, productivity and working efficiency and reduce the cost thereof by the arrangement. As the connecting sections 6 are formed at the given intervals, the separation of storage sections 2 can be carried out easily by breaking the connecting sections 6. |
