A microwaveable popcorn container may be fashioned from glassine or similar materials to provide a susceptor-free, biodegradable, and/or compostable container for cooking microwave popcorn. The material of the container may be translucent in order to advantageously permit inspection of contents during cooking, as well as to permit evaluation of the completeness of kernel popping after microwaving.
Claim CLM-00001. 1. A microwaveable food package, comprising:
popcorn that expands while cooking under an application of microwave energy, the popcorn having an expected volume after cooking; a container for the popcorn having a first end and a second end and including a plurality of sidewalls between the first end of the container and the second end of the container, the first end of the container configured to be opened after cooking, the plurality of sidewalls defining an interior volume within which the popcorn is disposed, a first sidewall of the plurality of sidewalls being formed of a translucent glassine material, the container being folded into a collapsed shape about the interior volume in a manner that permits expansion of the container into an expanded shape as the popcorn expands within the interior volume; a first opaque line on the first sidewall of the plurality of sidewalls, the first opaque line indicating the expected volume after cooking of 70% to 90% of a maximum volume of the interior volume of the container when the container is in the expanded shape; and a second opaque line on the first sidewall of the plurality of sidewalls, the second opaque line indicating a maximum volume of the popcorn in the container when the container is in the expanded shape after cooking.
Claim CLM-00021. 21. A microwaveable food package, comprising:
a container having a first end portion and a second end portion and a plurality of sidewalls extended between the first end portion and the second end portion, the container having a first volume when the container is in an unexpanded configuration and a second volume when the container is in an expanded configuration, the second volume being greater than the first volume, an entirety of the container being formed of a material that is biodegradable and compostable, the container being free of cooking additives, perfluorochemicals, plastic and susceptors, at least one sidewall from the plurality of sidewalls including a first opaque indicium disposed between the first end portion of the container and the second end portion of the container and a second opaque indicium disposed between the first opaque indicium and the first end portion of the container, the first opaque indicium and the second opaque indicium each being disposed within a folded portion of the at least one sidewall when the container is in the unexpanded configuration such that the first opaque indicium and the second opaque indicium are obscured from view, the first opaque indicium and the second opaque indicium being exposed when the container is in the expanded configuration; and popcorn disposed within the container, the popcorn configured to expand while cooking under an application of microwave energy, the popcorn having an expected volume after cooking, the first opaque indicium indicating the expected volume after cooking of 70% to 90% of the second volume of the container, the second opaque indicium indicating a maximum volume of the popcorn in the container after cooking.
