Abstract

A shipping container for shipping thermally active materials includes a plurality of structural panels that define a container interior, and are configured for receiving the thermally active materials. The container also includes an exterior disposed adjacent to an environment in which the shipping container is disposed. A thermal barrier member is placeable between the thermally active materials and the environment in which the container is placed. The thermal barrier includes a thermal barrier interior panel and a thermal barrier external panel defining a heat absorbing material receiving cavity. A flowable polymer based heat absorbing material is disposed within the heat absorbing material receiving cavity. The thermal barrier is configured to substantially surround the thermally active materials to reduce the passage of thermal energy between the thermally active materials and the environment in which the shipping container is disposed.

Claims

1. A shipping container configured for shipping thermally active materials, the shipping container comprising:

a plurality of structural panels defining a container interior configured for receiving the thermally active materials, and an exterior disposed adjacent to an environment in which the shipping container is placed,

a flowable, polymer based heat absorbing material disposed within the heat absorbing material receiving cavity, wherein the thermal barrier is configured to substantially surround the thermally active materials to reduce the passage of thermal energy between the thermally active materials and the environment in which the shipping container is disposed, wherein the polymer based heat absorbing material comprises a superabsorbentpolymer that is hydrated with water, wherein the superabsorbentpolymer is a polyacrylate/polyacrylamide copolymer.

2. A shipping container configured for shipping thermally active materials, the shipping container comprising:

a plurality of structural panels defining a container interior configured for receiving the thermally active materials, and an exterior disposed adjacent to an environment in which the shipping container is placed,

a thermal barrier member for placement between the thermally active materials and the environment in which a container is placed, the thermal barrier including a thermal barrier interior panel, and a thermal barrier exterior panel defining a heat absorbing material receiving cavity, and

a flowable, polymer based heat absorbing material disposed within the heat absorbing material receiving cavity, wherein the thermal barrier is configured to substantially surround the thermally active materials to reduce the passage of thermal energy between the thermally active materials and the environment in which the shipping container is disposed, wherein the polymer based heat absorbing material comprises a superabsorbentpolymer that is hydrated with water, wherein the superabsorbentpolymer is cross-linked with an oil.

3. The shipping container according to claim 2, wherein the oil is a mineral oil.

4. A shipping container configured for shipping thermally active materials, the shipping container comprising:

a plurality of structural panels defining a container interior configured for receiving the thermally active materials, and an exterior disposed adjacent to an environment in which the shipping container is placed,
