Patent ID: 8309896

Claim:
A blank for forming a microwave heating construct, comprising: a plurality of adjoined panels, the plurality of adjoined panels each having a first dimension extending in a first direction and a second dimension extending in a second direction substantially perpendicular to the first direction, the plurality of adjoined panels including a main panel, a first minor panel joined to the main panel, a second minor panel joined to the main panel, and a major panel joined to the first minor panel, wherein the main panel, the first minor panel, the second minor panel, and the major panel are joined respectively to one another along a plurality of respective substantially parallel fold lines extending in the first direction, and at least one of the main panel and the major panel includes microwave energy interactive material, and an end panel joined to the main panel along a substantially arcuate fold line extending generally in the second direction, wherein the end panel has an end edge opposite the arcuate fold line, wherein the end edge of the end panel is a free edge of the blank, and the end panel includes a pair of opposed side edges that extend divergently from the arcuate fold line to the end edge, such that the second dimension of the end panel increases from the arcuate fold line to the end edge.
