Abstract:
1. A process for producing a collapsible foam shipping cooler for perishables, the process comprising the steps of: providing a block of closed cell foam material; cutting the block of foam to form a sheet having a desired thickness, an interior surface and an exterior surface; cutting a series of linear grooves in the interior surface of the sheet, the grooves defining the juncture of adjacent foam panel sections; the grooves extending partially through the thickness of the sheet and leaving a foam portion between the exterior surface and the groove, the foam portion being a flexible hinge at the juncture of adjacent foam panels; cutting the sheet along a line perpendicular to the grooves to form a series of connected side panel sections in a collapsed mode, the series of connected side panel sections being movable between the collapsed mode and an assembled mode wherein adjacent panels of the series of panels are angularly disposed with respect to each other to form a closed loop sidewall section having a bottom perimeter edge and a top perimeter edge, wherein opposite ends of the series of adjacent panels are disposed adjacent to each other.
