Abstract
Microwaveable container that provides for accelerated microwave cooking times and more uniform internal temperature distribution. The container is manufactured from a laminate structure, the laminate structure including a first layer of microwave-transparent material and a second layer of microwave-reflective material. The second layer has at least one aperture defined therein, the at least one aperture having a width dimension W, a length dimension L, and a perimeter dimension P. The aperture is sized such that at least one of the width dimension W or length dimension L is sized about an energy maximum. Accordingly, the width and/or the length dimension is defined as within ⅛λ of a predetermined dimension D. The predetermined dimension is equal to ¼λ+n(½)λ, wherein n is an integer and λ is a microwave wavelength associated with a predetermined range of microwave frequencies. Preferably, the predetermined range of microwave frequencies is between about 2.0-3.0 GHz.
