Claims3
An insulated container comprising
- a leak proof exterior container component comprising a bottom panel, first and second opposed pairs of upstanding side walls and a cover member;
- and
- a first thermally insulating member within the exterior container component, the first insulating member having a bottom panel, opposed side panels and top panels, the opposed side panels of the first insulating member being aligned with the first opposed pair of side walls of the exterior container component wherein the bottom panel being integrally attached to the opposed side panels and the top panels being integrally attached to the opposed side panels,
- a second thermally insulating member within the first thermally insulating member, the second insulating member having a bottom panel, opposed side panels and top panels, the opposed side panels of the second insulating member being aligned with the second opposed pair of side walls of the exterior container component wherein the bottom panel being integrally attached to the opposed side panels and the top panels being integrally attached to the opposed side panels,
- the thermally insulating members being cellulose-based corrugated material encapsulated with a polymeric film, and wherein air is trapped within the corrugated material by the polymeric film.
