  • Patent number: 5361933
    Abstract: A storage shield provides a removable cover for placement on the surface of frozen ice cream remaining in an opened container, thereby partially sealing the surface of the ice cream from the air-filled voids. The shield, in one embodiment of the invention, is especially adapted for use in a conventional one-half gallon size, box-shaped ice cream carton. The shield is made from a transparent synthetic resin material, thus making it possible for the user to see any remaining air pockets through the shield. The shield, in this embodiment, is a rectangular-shaped planar device with smooth top, bottom, and sidewall surfaces. The corners of the shield are rounded slightly so that the shield can be easily inserted into the partially filled ice cream container with the bottom shield surface being slightly pressed to flatten the exposed surface of the ice cream. The ice cream is thereby partially protected from exposure to the air within the container and thereby deterioration is retarded.
