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.

B31B 7/00 - Machinery characterised by making lined or internally-reinforced boxes or cartons
B32B 3/12 - Layered products comprising a layer with external or internal discontinuities or unevennesses, or a layer of non-planar shapeLayered products comprising a layer having particular features of form characterised by a discontinuous layer, i.e. apertured or formed of separate pieces of material characterised by a layer of regularly-arranged cells whether integral or formed individually or by conjunction of separate strips, e.g. honeycomb structure
B32B 15/08 - Layered products essentially comprising metal comprising metal as the main or only constituent of a layer, next to another layer of a specific substance of synthetic resin
A thermal insulating liner for a container has a bottom panel, a pair of opposed end panels, a first side panel and an opposed second side panel. A first flap is hinged to the first side panel at a first hinge line and a second flap is hinged to the said second side panel at a second hinge line. The first flap and second flap are sized so that they are moveable between an open position whereat the first flap is spaced from said second flap and a folded position whereat a side margin of the first flap which extends along a side edge of the first flap opposite the first hinge line overlaps with a side margin of the second flap which extends along a side edge of the second flap opposite the second hinge line. Each flap comprises an outer sheet and an inner sheet spaced by a core with an innermost layer of the inner sheet comprising a metal foil layer. Each flap has a first thickness outside its side margin and a second, reduced, thickness, within its side margin. A thermal container may contain such a thermal insulating liner. A pair of dies can form a liner for a thermal container. A bottom a bottom die half has a bottom die pair of raised rectangular blocks and a top die half has a top die pair of raised rectangular blocks sized and positioned so as to register with the bottom die pair of rectangular blocks when the dies are brought together in use. The bottom die half has two spaced creasing rules between the bottom die pair of raised rectangular blocks and the top die half has two spaced creasing rules between the top die pair of raised rectangular blocks. The top spaced creasing rules are positioned so as to register with the bottom die spaced creasing rules when the dies are brought together in use.
