    Abstract: The invention relates to a nested pair of blanks on a unitary sheet which minimizes the amount of scrap sheet material (i.e., sheet scrap) upon separation of the blanks and construction of containers formed from the blanks. The nested pair of blanks provides a first blank for forming a container, a second blank for forming an identical container, and a non-linear separation interface that connects the first and second blanks to one another in a rotationally inverted relationship. The nested configuration reduces the amount of sheet scrap in the sheet. The invention further relates to a container formed from the first or second blank having features that reduce sheet scrap and offset the potential weakening of the container bottom resulting from reduced overlapping sheet material.
