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.

A thermal liner for a container comprises a bottom panel hingedly connected to a pair of opposed medial end panels and a pair of opposed side panels; four outer end panels each being hingedly connected along a first edge to a corresponding side panel and along a second edge to a corresponding medial end panel and being foldable along a diagonal thereof; a pair of opposed side flaps each being hingedly connected along an edge to a corresponding side panel; and end flaps hingedly connected along a first edge to one of a corresponding outer end panel or a corresponding side flap and having a free edge adjacent to the other one of the corresponding end panel or the corresponding side flap. There is also provided a thermal container comprising such a liner and a pair of dies for forming the thermal liner are also described.
摘要:
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.
