Abstract: A closure for a container comprises a base and a top cover. The base comprises a flange trap, a seal lock, and an opening. The top cover comprises a seal boss, a seal lock, a flange boss, and a top surface. The flange trap and flange boss secure the closure to a container when the closure is in a closed position. The seal locks are positioned to engage one another when the closure is in the closed position. The seal boss extends into the container when the closure is in the closed position to help prevent sauce or other liquid from leaking out of the container. A method for using a closure for a container and a container combination provides a closure and a container and arranges the closure so that the container is within the opening of the closure.

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 ?? of a predetermined dimension D. The predetermined dimension is equal to ¼?+n(½)?, wherein n is an integer and ? 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.
