  • Patent number: 4796411
    Abstract: A method of packaging food in raised state, comprising the steps of forming a displaceable wall portion integrally with and in the central section of a bottom wall of a food container so that the wall portion can be projected into and out of the container when the wall portion is pressed inward and outward, inserting a food in the container with the wall portion kept projecting outward, sealing the container with a film, and pressing the wall portion so as to be projected into the container and thereby raise the food above the plane of the upper end of the container against the tension of the film. Since the food is placed in the container with the displaceable wall portion kept projecting outward, the falling of the food during the food packing operation can be prevented.
