Foldable Transport Container with Insulating Intermediary

The patent applies nesting by placing conventional aluminum food containers inside a larger outer container with a base and sides. The inner containers are nested within the protective outer structure, allowing multiple containers to be transported together while the outer container provides the necessary support to prevent spillage and enables easy carrying via integrated handles.

The patent introduces an intermediary outer container made of heat-insulating material (such as cardboard or paperboard) that surrounds the metallic food containers. This intermediary layer blocks heat conduction from the warm contents to the handler's hands, preventing burns and discomfort while maintaining the lightweight and economical advantages of the inner metallic containers.

The patent segments the support function by separating it from the individual aluminum pans and assigning it to a dedicated outer container structure. The outer container's base and sides provide the necessary support across the bottom area to prevent spillage, while the inner aluminum pans remain simple and lightweight. This segmentation allows the support function to be provided once by the outer container, enabling hands-free or single-hand carrying.
