Abstract
A microwave corn popper device is provided including a rigid bowl having a bottom portion and an inclined side extending upward from the bottom portion and terminating at a top portion. A microwave susceptor is separate from the bowl and disposed within the bowl adjacent the bottom portion to receive kernels of corn. The susceptor becomes hot in the presence of microwave energy. A saucer-shaped metal plate is disposed beneath the susceptor at a predetermined spaced apart distance. The metal plate is part of a support assembly which is separately mountable to the bowl.
Claims34
A microwave corn popper device comprising:
- a bowl construction including:
- a closed bottom portion;
- and
- an inclined side extending upwardly from the bottom portion and terminating at a top portion, the bottom portion and the inclined side defining an enclosed bowl shape;
- a microwave susceptor disposed within the bowl construction adjacent the bottom portion to receive kernels of corn, the susceptor becoming hot in the presence of microwave energy;
- and
- a metal plate mounted to the bowl construction and disposed beneath the susceptor at a predetermined spaced apart distance, the metal plate including a portion disposed directly below the susceptor, the metal plate including a central planar portion, and an inclined outer peripheral portion disposed upwardly out of a plane defined by the central planar portion.

A microwave corn popper device comprising:
- a bowl construction including:
- a closed bottom portion;
- an inclined side integral with the bottom portion and extending upwardly from the bottom portion and terminating at a top portion, the bottom portion and the inclined side defining an enclosed bowl shape;
- and
- a support assembly for supporting the bottom portion of the bowl construction at a spaced apart distance from a horizontal surface, the support assembly including two mating halves mounted to one another;
- a microwave susceptor disposed within the bowl construction adjacent the bottom portion to receive kernels of corn, the susceptor becoming hot in the presence of microwave energy;
- and
- a metal plate mounted to the support assembly and disposed beneath the susceptor at a predetermined spaced apart distance, the metal plate including a portion disposed directly below the susceptor, the metal plate disposed between the mating halves of the support assembly.
