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.
Claims19
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, the plurality of adjoined panels including
- a main panel having
- a first end defining at least a portion of a peripheral edge of the blank,
- a second end opposite the first end, and
- a pair of opposed side edges, and
- an end panel joined to the second end of the main panel along a pair of spaced apart, substantially arcuate fold lines;
- 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 by a line of disruption initiating and terminating at the peripheral edge between and at a distance from each side edge of the main panel, the line of disruption including a portion that extends into the end panel between the arcuate fold lines to define a tab.
6 more elements
A construct for heating, browning, and/or crisping a food item therein, comprising:
- a first main panel and a second main panel in an opposed configuration;
- a first minor panel and a second minor panel in an opposed configuration, the first minor panel and the second minor panel being joined to the first main panel and the second main panel along respective fold lines to at least partially define an interior space, wherein the first main panel, the second main panel, the first minor panel, and the second minor panel each have a respective first end defining an opening at a first end of the construct and a respective second end opposite the first end;
- an end panel foldably joined to the second end of the first main panel, the end panel being adapted to be folded inwardly towards the interior space;
- and
- a microwave energy interactive element overlying at least a portion of at least one of the first main panel, second main panel, first minor panel, and second minor panel on a side of the respective panel facing the interior space,
- wherein the construct includes a removable portion defined by a line of disruption initiating and terminating at the first end of the construct within the first main panel, the line of disruption including a portion that extends into the end panel to define a tab, wherein the tab extends from and lies in the same plane as the first main panel.
