An improved shock absorbing insulated shipping container including an external corrugated cardboard box, receiving a product box therein. Peripheral spaced, and upper and lower spaced between the external box and the product box receive insulating pellets, which are maintained under a compressive force in order to interlock these insulating pellets and prevent their migration during transit of the shipping container. By preventing migration of the insulating pellets, the formation of a void (or voids) in the insulation of the container is prevented, and the formation of a hot spot (or hot spots) within the container which could degrade or damage the product in transit is prevented. A most preferred embodiment utilized insulating pellets made of puffed vegetable starch, so that substantially the entire container can be recycled, is biodegradable, or can be composted.

1. An improved insulated and cushioning shipping container, said shipping container comprising: an exterior cardboard box defining a floor wall, and plural side walls, said walls cooperatively defining a cavity and an opening to said cavity, and means for closing said opening;wall structure within said cavity and defining a product cavity;a mass of insulating material of pellet/granular form received and distributed substantially about said product cavity between said wall structure and said exterior cardboard box; andsaid wall structure being configured for applying a compressive stress and strain to said insulating material in at least one of three mutually orthogonal horizontal “x”, “y”, and “z” directions, so that said pellets/granules of insulating material mutually engage and interlock with one another, whereby said insulating material is inhibited from migration during shipping of said container;wherein a portion of said insulating material is disposed in an insulating and cushioning pad member disposed within said wall structure, whereby said insulating and cushioning pad is subjected to compressive stress and strain within said wall structure to effectively compressively interlock said insulating material against migration of said pellet/granular insulating material during transit of said shipping container. 2. The insulated shipping container of claim 1 wherein said pad member defines a length dimension and a width dimension cooperatively defining a face size for said pad member, and said pad member further defining a thickness dimension, and said compressive stress is applied facially across the thickness of said pad member. 3. The insulated shipping container of claim 2 wherein two portions of said insulating material are disposed in respective ones of a pair of insulating and cushioning pad members, and said wall structure applies compressive stress to each of said pair of pad members to interlock the insulating material against migration during transit, and said wall structure defines a length dimension, said pair of pad members exceeding said length dimension by a selected amount such that said pair of pad members interfere resiliently with one another to place said pair of pad members and the insulating material therein also into compressive stress in a second of said “x”, “y”, and “z” directions along one of the length and width of said pad members. 4. The insulated shipping container of claim 3 wherein said wall structure further applies a compressive stress to said pair of pad members in the other of said length and width directions so that said insulating material of pellet/granular form is subject to compressive stress in each of said “x”, “y”, and “z” directions, and said product cavity remains free of insulating material therein. 5. The insulated shipping container of claim 3 wherein three portions of said insulating material are disposed in respective ones of three insulating and cushioning pad members, and said wall structure applies compressive stress to each of said three pad members to interlock the insulating material therein against migration during transit, and said wall structure defines both a length dimension and a width dimension, two of said three pad members exceeding said length dimension by a selected amount such that said two pad members contact and interfere resiliently with one another to place said two pad members and the insulating material therein into compressive stress in a second of said “x”, “y”, and “z” directions along said length dimension, and said third pad member contacting and interfering resiliently with said two pad members to place said two pad members into compressive stress along a third of said “x”, “y”, and “z” directions. 6. A method of providing an improved insulating and cushioning shipping container, said method comprising steps of: providing an exterior box defining a floor wall and plural side walls cooperatively defining a cavity there within, and an opening to said cavity, and means for closing said opening;providing a plurality of insulating and cushioning pillow members;providing said plurality of pillow members each with an air permeable flexible casing having a length and width cooperatively defining a facial size for each pillow member, and a thickness, and within each of said plurality of pillow members providing a respective mass of insulating material of pellet/granular form;providing a wall structure including respective pairs of cooperating walls, each pair of cooperating walls receiving a respective one of said plurality of pillow members therebetween in facial contact, and utilizing said pairs of cooperating walls to applying a selected facial compressive stress and strain to said insulating material within said plurality of pillow members; andemploying said selected compressive stress and strain to mutually interlock the mass of insulating material of pellet/granular form within said plurality of pillow members so as to inhibited migration of said insulating material during transit of said shipping container. 7. The method of claim 6 further including the step of configuring said respective pillow members so that each exceeds by a selected amount at least one of the length and width dimensions of said pair of cooperating wall receiving said respective pillow member therebetween. 8. The method of claim 7 wherein the excess in length or width of each pillow member is utilized to form a protruding portion of the respective pillow member, and the protruding portions of adjacent pillow members are forcefully engaged resiliently with one another in order to inhibit respiration of air into and out of said product cavity. 9. An improved insulating and cushioning shipping container, said container comprising: an exterior box defining a floor wall and plural side walls cooperatively defining a cavity there within, and an opening to said cavity, and means for closing said opening;a plurality of insulating and cushioning pillow members received into said cavity adjacent ones of said floor wall, said plural side walls, and adjacent to said means for closing said opening, said plural insulating and cushioning pillow members cooperatively defining a product sub-cavity within said cavity;each of said plurality of insulating and cushioning pillow members including an air permeable flexible casing having a length and width cooperatively defining a facial size for each respective pillow member, and a thickness, andwithin said cavity and about said product sub-cavity, a wall structure including respective pairs of cooperating walls, each pair of cooperating walls receiving a respective one of said plurality of pillow members therebetween in facial contact, and means for urging said pairs of walls toward one another sandwiching and capturing the respective one of said plural pillow members therebetween in facial compressive stress applied to said insulating material of pellet/granular form within said pillow members, whereby said insulating material is interlocked against movement, andeach of said plurality of pillow members being configured to exceed by a selected amount at least one of the length and width dimensions of said pair of cooperating wall members receiving and sandwiching said respective pillow member therebetween;whereby adjacent ones of said plurality of pillow members forcefully engaged resiliently with one another in order to inhibit respiration of air into and out of said product cavity.
