Abstract
Abstract A microwave popcorn popper has a generally cylindrical open topped container with a snap on domed cover. A raised downwardly and outwardly tapering frusto conical partition is provided in the container, above an interior flat circular floor of the container. An elongated cylindrical tube extends through a central circular aperture in the partition and has a bottom end resting on the flat circular floor. An upwardly opening conical receptacle is provided in the bottom portion of the tube for holding a quantity of unpopped corn and oil. A circular cap over and open top end of the tube is formed by two semi-circular plates connected by a central hinge. In use, a quantity of unpopped corn is placed in the conical receptacle and the entire unit is placed in a conventional microwave oven. The conical receptacle concentrates the corn kernels at the central focal point of the microwaves within the oven. As the kernels pop, they move upward through the tube and exit through the pivotal cap into the surrounding container. A dispersing receptacle may be provided on the pivotal tube cap to dispense salt or butter on the popcorn if desired.
