Claims
- 1. An expandable popcorn bag for microwave popping of popcorn comprising,
- a bag body formed from flexible microwave transparent sheet material including superimposed upper and lower face panels having parallel left and right side edges, longitudinally extending centrally projecting gussets folded between the upper and lower face panels,
- said bag having top and bottom cut ends, top and bottom seals aligned adjacent to the cut ends of the bag,
- said seals bonding the upper and lower face panels together and bonding the gussets between the face panels to seal the ends of the bag whereby said bag expands to accommodate expansion of popcorn as the popcorn pops therein during microwave cooking,
- said lower face panel having a microwave heating susceptor for absorbing microwave energy to enhance the popping of said popcorn,
- a collapsible stand as a part of the bag bonded to an outside surface of the lower face panel of said bag below the susceptor for supporting said bag in spaced relationship above a cooking surface when the stand is erected,
- said stand is folded to a collapsed condition so that said stand occupies a reduced space during shipment and storage,
- said stand enables the bag to be placed in selected positions within said microwave oven during cooking including a) a lower position when the stand is folded to the collapsed condition and b) a raised position when the stand is folded to an erect condition,
- said stand being thereby adapted to support the bag in said selected positions during cooking while the bag remains sealed for improving cooking efficiency in microwave ovens,
- said stand comprises base portions adhesively bonded to an outer surface of said lower panel of the bag,
- at least two upright panels spaced apart from one another and connected to said base portions by means of fold lines whereby the upright panels serve as legs for supporting the bag in a raise position when the stand is erected and the legs are upright, and
- means for securing at least one of said legs in an erect position.
- 2. The popcorn bag of claim 1 wherein said susceptor comprises a sheet of susceptor material located at said lower force panel of said bag to which said stand is attached.
- 3. The popcorn bag of claim 1 wherein the susceptor is attached to the lower face panel and said susceptor comprises a thin film of plastic resinous material having a semiconductive metal-containing coating thereon for converting microwave energy to heat for enhancing cooking of the popcorn and said stand is bonded to an outside surface of the lower face panel proximate to said susceptor.
- 4. The popcorn bag of claim 1 wherein the bag has top and bottom cut ends and each of the cut ends is contoured to provide a convex arcuate cut end at each end of the bag, arcuate lines of adhesive are aligned adjacent to the convex arcuate cut ends of the bag, said arcuate lines of adhesive bond said face panels together and bond the gussets between the face panels, the gussets have top and bottom cut ends, the top and bottom cut ends of the gussets are cut so that the length of each gusset is greatest near the center of the bag and diminishes proceeding outwardly toward side edges of each face panel.
- 5. The popcorn bag of claim 4 wherein the arcuate-cut ends of the bag and gussets are curved arcs.
- 6. The popcorn bag of claim 4 wherein the arcuate cut ends of the bag are formed from a plurality of straight segments connected end-to-end.
- 7. The popcorn bag of claim 1 wherein the stand includes a bottom panel connected between the lower ends of said legs by spaced apart mutually parallel fold lines which are also positioned parallel to said fold lines between said base portions and said legs.
