Thermal container

摘要

A thermal insulating liner for a container lid has a top sheet and a bottom sheet spaced by a core. The bottom sheet has an exterior metal foil layer. A side edge-to-side edge transverse cut line extends through the bottom sheet proximate each of two opposed ends of the liner. The liner has reduced thickness end margins extending between each said side edge-to-side edge transverse cut line and each of the opposed ends. A die to make the lid liner has a central well and, proximate each end of the die, an upward step to a land with an inside edge of the step having a ramp surface. A first cutting blade protrudes upwardly from the land and a second cutting blade protrudes upwardly above the land at each end of the die and above the level of the first cutting blade.

主权项

1. A thermal insulating liner insertable in a container body, said thermal insulating liner comprising:
a top sheet and a co-extensive bottom sheet spaced by a co-extensive core having honeycomb-shaped cells extending between said top sheet and said bottom sheet; said bottom sheet comprising a metal foil layer; said liner having two opposed ends and reduced thickness end margins extending parallel and proximate to the two opposed ends wherein the honeycomb-shaped cells of the core in the reduced thickness end margins are partially crushed and maintain an air spacing therebetween.
