Insulated container system for shipping perishable products

Claim 2

An insulated container system for shipping perishable products comprising: (a) an outer container having a top and a bottom, each of said top and said bottom comprising a rectangular sheet of container material, said rectangular sheets of container material folded such that said top has a substantially rectangular ceiling and said bottom has a substantially rectangular floor, such that said ceiling and said floor are encompassed by side walls and end walls and such that said top and said bottom have regions composed of a single layer of said container material, said top and said bottom having corners formed by inwardly folded sections of said rectangular sheets, said inwardly folded sections being fastened to single layered portions of said top and said bottom thereby forming multilayered regions; (b) a one-piece insulating liner formed of an unbacked, separate single sheet of foam insulating material for covering said single layered regions of said bottom of said outer container when said one-piece insulating liner is inserted into said bottom but not said multilayered regions, said one-piece insulating liner comprising: (i) a rectangular floor region; (ii) two side wall regions; and, (iii) two end wall regions, said two side wall regions and said two end wall regions being unitarily joined together with said floor region such that said two side wall regions and said two end wall regions form an integral structure with said floor region, said one-piece insulating liner including compression creases where said two side wall regions and said two end wall regions join said floor region; and, (c) an insulating lid formed of a single sheet of foam insulating material for covering said ceiling of said top of said outer container when said insulating lid is inserted into said top.

Claim 3

The insulated container system claimed in claim 1, wherein said multilayered regions of said top and bottom are triangular.

Claim 4

The insulated container system claimed in claim 1, wherein said inwardly folded sections are fastened to said side walls of said top and said bottom.

Claim 5

The insulated container system claimed in claim 3, wherein said multilayered regions of said top and bottom are triangular.

Claim 6

The insulated container system claimed in claim 4, wherein said side walls of said top and bottom have single layered center side wall portions located between said multilayered regions.

Claim 7

The insulated container system claimed in claim 5, wherein said single layered center side wall portions of said side walls are trapezoidal.

Claim 8

The insulated container system claimed in claim 6, wherein said container material is a single layer of corrugated cardboard.

Claim 9

The insulated container system claimed in claim 7, wherein said single layer of corrugated cardboard is coated with a moisture repellant substance.

Claim 10

The insulated container system claimed in claim 1, wherein said foam insulating material is expanded polystyrene.

Claim 11

The insulated container claimed in claim 9, wherein said expanded polystyrene has a density falling in the range of 1.5-2.0 pounds per cubic foot.

Claim 12

An insulated container system for shipping perishable products comprising: (a) a telescoping container constructed of corrugated cardboard, said container having a floor, a ceiling, side walls and end walls, predetermined regions of said floor, ceiling, side walls and end walls composed of a single layer of said corrugated cardboard, said telescoping container having a top and a bottom, each of said top and said bottom comprising a sheet of container material, said sheets of container material folded such that said top has a ceiling and said bottom has a floor, such that said ceiling and said floor are encompassed by walls and such that said top and said bottom have regions composed of a single layer of said container material, said top and said bottom having corners formed by inwardly folded sections of said sheets, said inwardly folded sections being fastened to single layered portions of said top and said bottom thereby forming multilayered regions; (b) a one-piece insulating liner formed of an unbacked, separate single sheet of foam insulating material for covering said single layered predetermined regions of said floor and said walls of said telescoping container when said one-piece insulating liner is inserted into said telescoping container, said one-piece insulating layer comprising: (i) a floor region; and (ii) a plurality of wall regions unitarily joined together with said floor region such that said wall regions form an integral structure with said floor region, said one-piece insulating liner including compression creases where said wall regions join said floor region; and, (c) an insulating lid formed of a single sheet of foam insulating material for covering said ceiling of said telescoping container when said insulating lid is located in said telescoping container.

Claim 13

An insulated container system for shipping perishable products comprising: (a) a telescoping container constructed of corrugated cardboard, said container having a floor, a ceiling, side walls and end walls, predetermined regions of said floor, ceiling, side walls and end walls composed of a single layer of said corrugated cardboard, said telescoping container having a top and a bottom, each of said top and said bottom comprising a sheet of container material, said sheets of container material folded such that said top has a ceiling and said bottom has a floor, such that said ceiling and said floor are encompassed by walls and such that said top and said bottom have regions composed of a single layer of said container material, said top and said bottom having corners formed by inwardly folded sections of said sheets, said inwardly folded sections being fastened to single layered portions of said top and said bottom thereby forming multilayered regions; (b) a one-piece insulating liner formed of an unbacked, separate single sheet of foam insulating material for covering said single layered predetermined regions of said floor and said walls of said telescoping container when said one-piece insulating liner is inserted into said telescoping container, said one-piece insulating layer comprising: (i) a floor region; and (ii) a plurality of wall regions unitarily joined together with said floor region such that said wall regions form an integral structure with said floor region, said one-piece insulating liner including compression creases where said wall regions join said floor region; and, (c) an insulating lid formed of a single sheet of foam insulating material for covering said ceiling of said telescoping container when said insulating lid is located in said telescoping container.

Claim 14

The insulated container system claimed in claim 11, wherein said foam insulating material is expanded polystyrene.

Claim 15

The insulated container system claimed in claim 12, wherein said expanded polystyrene has a density falling in the range of 1.5-2.0 pounds per cubic foot.

Claim 16

The insulated container system claimed in claim 11, wherein said floor of said one-piece insulating liner is rectangular, said plurality of side walls comprising two quadrilateral side walls adjacent opposite sides of said rectangular floor and said plurality of end walls comprising two quadrilateral end walls adjacent opposite side of said rectangular floor, such that said two quadrilateral end walls are substantially perpendicular to said two quadrilateral side walls.

Claim 17

The insulated container system claimed in claim 14, wherein said two quadrilateral side walls are trapezoidal and said two quadrilateral end walls are rectangular.
