Abstract
A construct includes at least one panel for supporting a food product, the at least one panel formed from a laminate structure having a base layer, a conductive layer, and a surface film. The construct further includes at least one spacing feature extending downwardly from the at least one panel for supporting the at least one panel a distance above an induction source for attenuating heat transferred to the food product in response to an oscillating magnetic field interacting with the conductive layer of the laminate structure.
Claims54
A construct, the construct comprising:
- at least one panel for supporting a food product, the at least one panel formed from a laminate structure comprising a base layer, a conductive layer, and a surface film;
- and
- at least one spacing feature extending downwardly from the at least one panel for supporting the at least one panel a distance above an induction source for attenuating heat transferred to the food product in response to an oscillating magnetic field interacting with the conductive layer of the laminate structure.
A blank for forming a construct, the blank comprising:
- at least one panel for supporting a food product, the at least one panel formed from a laminate structure comprising a base layer, a conductive layer, and a surface film;
- and
- features for forming at least one spacing feature extending downwardly from the at least one panel for supporting the at least one panel a distance above an induction source for attenuating heat transferred to the food product in response to an oscillating magnetic field interacting with the conductive layer of the laminate structure when the construct is formed from the blank.
A method of forming a construct, the method comprising:
- obtaining a blank comprising at least one panel formed from a laminate structure comprising a base layer, a conductive layer, and a surface film;
- and
- forming at least one spacing feature extending downwardly from the at least one panel to support the at least one panel a preselected distance above an induction source for attenuating heat transferred to a food product in response to an oscillating magnetic field interacting with the conductive layer of the laminate structure.
A method of heating a food product, the method comprising:
- obtaining a blank comprising at least one panel formed from a laminate structure comprising a base layer, a conductive layer, and a surface film;
- and
- forming a construct from the blank such that the construct comprises the at least one panel and at least one spacing feature extending downwardly from the at least one panel;
- positioning the construct on an induction source with the at least one spacing feature supporting the at least one panel a distance above the induction source;
- and
- activating the induction source to produce an oscillating magnetic field interacting with the conductive layer of the laminate structure to heat at least one food product supported on the at least one panel.
