One-piece insulating container

6) A method of forming an insulated container, said method comprising the steps of:

• providing a generally flat case blank adapted to foldably form a three-dimensional container having interior surfaces when folded, wherein the case blank has four sections arranged in a row, wherein each section comprises a side wall subsection and opposing flaps attached to each side wall subsection;
• providing a foldable insulation template shaped to cover the side wall subsections of all four sections and to cover two opposing flaps of one of the four sections;
• securing the insulation template to one side of the case blank in a position in which the insulation template covers the side wall subsections of all four sections of the case blank and covers two opposing flaps of one of the four sections;
• and
• folding the case blank and the insulation template simultaneously, after the step of securing the insulation template to one side of the case blank, to form a three-dimensional container in which all interior surfaces of the three-dimensional container are covered by the insulation template.
