Abstract: A can, bottle or other food product is placed inside a laminated cooler and/or warmer constructed of an inner liner surrounded by a thermal retentive slab surrounded by an optional insulation layer surrounded by a protective shell. Optionally an opening with integrated closure is provided to allow easier insertion of the food product into the interior. The gap space between the liner and food product is preferably minimized to allow thermal flow to or from slab to the food.
