ABSTRACT:
A microwave container (2) including a folded body forming a box having first, second, third and fourth sides (4, 26, 6, 28). The sides have first, second, third and fourth side edges, respectively, defining an end (14). A flap (10, 30, 32, 38) extends from each side and is attached at the edge of each side. A sealing region (34) is defined at the intersection of the first flap (10) and each of the adjacent flaps (30, 32) at the corners of the box formed by the first side (4). A notch (40) is formed between the first flap and each of the adjacent flaps before folding. A common seam (44) runs a chosen distance (43) from the corners (18, 20) such that when the first flap and the adjacent side flaps are folded, holes (36) normally formed at the corners are spaced therefrom. The remaining flap (38), opposite the first flap, is folded to cover and seal these holes.
