Abstract
Various blanks are provided for forming sleeves, containers, and other constructs for heating, browning, and/or crisping of a food item in a microwave oven, and for holding and/or transporting the food item after heating. The various blanks, sleeves, containers, and other constructs include a removable portion defined by one or more lines of disruption that enable the removable portion to be separated from the remainder of the blank, sleeve, container, or other construct.
Claims39
A blank for forming a construct, comprising:
- a plurality of adjoined panels, each panel having a first dimension extending in a first direction and a second dimension extending in a second direction substantially perpendicular to the first direction, wherein the adjoined panels define a plurality of peripheral edges of the blank including a first peripheral edge extending in the second direction;
- and
- a microwave energy interactive element overlying at least a portion of at least one of the adjoined panels,
- wherein the blank includes a removable portion defined at least partially by
- a transverse tear line extending in the second direction substantially across the adjoined panels,
- an oblique tear line substantially abutting the transverse tear line, and
- a cutout adjacent to the oblique tear line.
