  • Patent number: 4753469
    Abstract: A cooking device for holding a food pouch to be heated in a microwave oven comprises a molded plastic receptacle formed to provide a bottom wall, have a pair of opposed side walls and a pair of opposed end walls upstanding therefrom. One of the end walls is separated vertically in its central area into two parts, and the bottom wall is bifurcated thereby providing side walls movable away from and toward one another. A food pouch disposed within the side walls and end walls and resting on the bottom wall is positioned so that a marginal portion of the food pouch is disposed in the vertical separation of the one end wall whereby movement of the side walls toward one another will cause the two parts of the one end wall to grip the marginal portion. The pouch holder can be grasped and manipulated to transport and empty the food pouch without the necessity of handling the food pouch directly.
