ABSTRACT:
A reusable bag system for use in popping popcorn kernels is a microwave oven. The system provides a foldable bag having front and rear walls joined by foldable side walls, a closed bottom wall, and an open mouth. The bag is closeable by double folding the bag over in its mouth region. Creased lines separated from one another by one-half inch from the open mouth on the front and rear walls of the bag aid the user in accurately double folding the mouth region closed. The system uses a microwave safe plastic closure clip having two spaced apart side walls joined at their upper region, and having inwardly directed pressure exerting ridges to air-tightly close the bag. Unpopped kernels are placed in the bag and sealed therein. To use the bag system, the consumer places popcorn kernels into the bag through its open mouth and folds over the mouth region of the bag to thereby close the bag; the closure clip is installed on the folded-over mouth region to thereby air-tightly close the bag with the popcorn kernels inside.
