Lid of a packaging container

Abstract

This item, as shown in the "Reference Diagram Showing Usage," is a lid for packaging containers made of polystyrene foam or similar materials used to pack fresh foods and other perishable items. As shown in the "Reference Diagram Showing the Translucent Part," the inside of this item in a plan view is made of a transparent or translucent material such as acrylic. Therefore, as shown in the "Reference Diagram Showing Usage," it is possible to see the contents of the packaging container from the outside even with the lid of this item in place. Because the inside of the container can be seen without opening the lid, it enables product display and provision while suppressing temperature changes inside the container. Furthermore, as shown in "Perspective View 1," "Perspective View 2," and "Cross Section Diagram," the transparent or translucent material has a two-layer structure, so even if the contents of the packaging container are refrigerated or frozen and the inside of the container is at a low temperature, condensation is prevented and visibility from the outside is not obstructed.
