Insulated container
An insulated container may include a rigid container surrounding an insulation layer formed from a post-industrial, pre-consumer card waste. The insulation layer may be characterized by a lack of any wrapping material. The insulation layer may be manufactured using a variety of converting processes including, carding, airlay, and needle punch to form a non-woven material for providing consistent density throughout the insulation layer. The insulation layer may include a natural fiber lamination layer on an outer surface of the insulation layer. The insulation layer may be biodegradable in an anaerobic environment.
1. An insulated container comprising:
an insulation layer comprising a pair of insulation pads wherein each one of the pads has a top surface, a bottom surface, and four edge surfaces, wherein the top surface and the bottom surface comprise contact surfaces; and
a natural fiber lamination layer, comprising only a single layer, applied to the contact surfaces of the top surface and/or the bottom surface of the insulation pads but not to any of the edge surfaces of the insulation pads.
2. The insulated container of claim 1 further comprising a rigid container surrounding the insulation layer.
3. The insulated container of claim 2 wherein the rigid container is made from cardboard.
4. The insulated container of claim 2 wherein one of the interlocking C-shaped members has a top portion which is integrally hingedly formed in the member for providing access to an interior portion of the insulated container.
5. The insulated container of claim 1 wherein the insulation layer is biodegradable in an anaerobic environment.
6. The insulated container of claim 1 wherein the insulation layer is formed from cotton waste.
7. The insulated container of claim 6 wherein the cotton waste is post-industrial, pre-consumer cotton waste.
8. The insulated container of claim 1 wherein the insulation layer is non-woven material for providing consistent density throughout the insulation layer.
9. The insulated container of claim 1 wherein insulation pads comprise a pair of interlocking C-shaped members forming an enclosed cube-shaped cavity.
10. The insulated container of claim 1 wherein the insulation layer is capable of maintaining a constant internal temperature for 48 hours where three 500 ML and two 250 ML IV bags are cooled by four 24 oz frozen ice packs placed at the top and bottom below a payload.
