The present invention relates generally to methods and systems for maintaining temperature-sensitive materials within a desired temperature range for a period of time and relates more particularly to a novel product box for use in a shipping system for maintaining temperature-sensitive materials within a desired temperature range for a period of time.
There is a continuing need for systems that can maintain temperature-sensitive materials within a desired temperature range for an extended period of time. For example, many pharmaceuticals, biological materials, medical devices, foods, beverages, and other temperature-sensitive materials must be maintained within a particular temperature range (such as, for example, +2° C. to +8° C.) in order to prevent the spoilage of such materials. As can readily be appreciated, the maintenance of such materials within a desired temperature range while such materials are being transported and/or stored can be challenging. One way in which such temperature maintenance may be achieved is by transporting and/or storing such materials in active temperature-control devices, such as electrically-powered refrigeration units or the like. However, as can be appreciated, such active temperature-control devices add considerable expense to transportation and/or storage costs.
An alternative approach to temperature maintenance during transportation and/or storage is to place the temperature-sensitive materials within an insulated container that also contains one or more passive temperature-control members, such as, but not limited to, ice packs, gel packs, dry ice, wet ice, or the like. In some cases, such as in the case of an ice pack or a gel pack, the passive temperature-control member typically comprises a quantity of a phase-change material (PCM) disposed within a suitable casing or container. In other cases, such as in the case of dry ice or wet ice, the passive temperature-control member may be loose within the insulated container.
Often, the temperature-sensitive materials are housed within a product box (sometimes alternatively referred to as “a payload box”) that, in turn, is housed within the insulated container. The product box, which is typically made of a corrugated cardboard or similar material, is typically shaped to have four equal sides, a top, and a bottom, thereby defining a uniform rectangular prismatic cavity. The product box typically serves to provide a barrier between the temperature-sensitive materials, which are placed within the product box, and the passive temperature-control member(s), which are placed outside of the product box but within the insulated container. In this manner, the product box helps to keep the temperature-sensitive materials from coming into direct contact with the passive temperature-control member(s) and, consequently, getting too cold. In addition, the product box helps to keep the temperature-sensitive materials from becoming wet as the passive temperature-control member(s) melt(s).

Product box 11 may comprise a front 13, a rear 15, a left side 17, a right side 19, a plurality of lower flaps 21 and 23, a first plurality of upper flaps 25 and 27, and a second plurality of upper flaps 29 and 31.
Front 13 and rear 15 may extend generally vertically and parallel to one another and may have substantially matching lengths and widths. Left side 17 and right side 19 may extend generally vertically and parallel to one another and may have substantially matching lengths and widths. Each of left side 17 and right side 19 may be generally perpendicular to each of front 13 and rear 15. The lengths (i.e., heights) of front 13 and rear 15 may be greater than the lengths (i.e., heights) of left side 17 and right side 19. For example, each of front 13 and rear 15 may have a length that is approximately 1 inch greater than the length of each of left side 17 and right side 19. The lower edges of front 13, rear 15, left side 17, and right side 19 may be substantially aligned with one another. As a result, the upper edges of front 13 and rear 15 may extend upwardly beyond the upper edges of left side 17 and right side 19 to create an air gap of about 1 inch.
Front 13 may be integrally connected along its left vertical edge to left side 17 and may be integrally connected along its right vertical edge to right side 19. Rear 15 may be integrally connected along one vertical edge to left side 17 and may be joined to right side 19 using a panel 33. More specifically, panel 33 may be integrally connected along one vertical edge to rear 15 and may have its outer face secured to the inner face of right side 19 using an adhesive tape 20 or other suitable means. (In the present embodiment, tape 20 is shown as transparent but need not be.)
Lower flap 21 may be integrally connected along its front edge to the lower edge of front 13 and may extend generally perpendicularly relative to front 13 (i.e., generally horizontally). Lower flap 23 may be integrally connected along its rear edge to the lower edge of rear 15 and may extend generally perpendicularly relative to rear 15 (i.e., generally horizontally). The rear edge of lower flap 21 and the front edge of lower flap 23 may be secured to one another using an adhesive tape 22 or other suitable means. (In the present embodiment, tape 22 is shown as transparent but need not be.) When secured to one another, flaps 21 and 23 may define the lower boundary of an interior cavity 24 of product box 11, and flaps 21 and 23 may substantially close interior cavity 24 of product box 11 at its lower end.
Upper flap 25 may be integrally connected along its left edge to the upper edge of left side 17 and may extend generally perpendicularly relative to left side 17 (i.e., generally horizontally). Upper flap 27 may be integrally connected along its right edge to the upper edge of right side 19 and may extend generally perpendicularly relative to right side 19 (i.e., generally horizontally). The right edge of upper flap 25 and the left edge of upper flap 27 may be secured to one another using adhesive tape 26 or other suitable means. (In the present embodiment, tape 26 is shown as transparent but need not be.) When secured to one another, flaps 25 and 27 may define the upper boundary of interior cavity 24 of product box 11, and flaps 25 and 27 may substantially close interior cavity 24 of product box 11 at its upper end. As can be seen, in the present embodiment, interior cavity 24 may be a generally rectangular prismatic cavity but need not be.
Upper flap 29 may be integrally connected along its front edge to the upper edge of front 13 and may extend generally perpendicularly relative to front 13 (i.e., generally horizontally), and upper flap 31 may be integrally connected along its rear edge to the upper edge of rear 15 and may extend generally perpendicularly relative to rear 15 (i.e., generally horizontally). The rear edge of upper flap 29 and the front edge of upper flap 31 may be secured to one another using adhesive tape 28 or other suitable means. (In the present embodiment, tape 28 is shown as transparent but need not be.) Due, at least in part, to the fact that the upper edges of front 13 and rear 15 extend above the upper edges of left side 17 and right side 19 when upper flaps 29 and 31 are secured to one another, a space 35 may be formed above flaps 25 and 27 and below flaps 29 and 31. Space 35, which may be filled with or contain air, may serve to thermally insulate, to a certain extent, items in interior cavity 24 of product box 11 from a passive temperature-control member positioned on top of flaps 29 and 31. This may be advantageous, for example, in circumstances in which the passive temperature-control member, if sitting directly on top of a conventional product box, would cause the contents of the product box to become too cold. Consequently, such an approach may obviate the need to position materials, like bubble wrap, between the top of the product box and the passive temperature-control member to keep the contents of the product box from becoming too cold.
Product box 11 may further comprise a plurality of tabs or wings, a first wing 37 integrally connected to flap 29 and extending outwardly at the interface of front 13 and flap 29, a second wing 39 integrally connected to flap 31 and extending outwardly at the interface of rear 15 and flap 31, a third wing 41 integrally connected to flap 25 and extending outwardly at the interface of left side 17 and flap 25, and a fourth wing 43 integrally connected to flap 27 and extending outwardly at the interface of right side 19 and flap 27. Wings 37, 39, 41 and 43, which may be cut out from front 13, rear 15, left side 17, and right side 19, respectively, may be appropriately dimensioned to engage the inside surfaces of the front, rear, and side walls of an insulated container into which product box 11 may be positioned and, in so doing, may space front 13, rear 15, left side 17, and right side 19 from the aforementioned walls of the insulated container. This may allow air to circulate around product box 11, thereby minimizing temperature gradients around product box 11. According to one embodiment, wings 37, 39, 41 and 43 may be dimensioned to one another. In this manner, product box 11 may be generally centered relative to the vertical walls of the insulated container by wings 37, 39, 41 and 43.

Blank 51 may be appropriately dimensioned to make a product box having inner dimensions of 8⅝ inches (length)×8½ inches (width)×9 inches (depth). It is to be understood that these dimensions are merely exemplary.
Product box 11 may be used as a part of many different types of shipping systems and may be used to keep payloads within various target temperature ranges, such as, but not limited to, −20° C.±5° C. (frozen), +5° C.±3° C. (refrigerated), and +20° C.±5° C. (room temperature). For example, product box 11 may be disposed within the cavity of an insulated container (which may be made of, for example, expanded polystyrene or the like), which, in turn, may be disposed within an outer container made of, for example, corrugated cardboard or the like. One or more passive temperature-control members may also be positioned within the insulated container in contact with (or near) one or more outer surfaces of product box 11.

Product box 111 may comprise a front 113, a rear 115, a left side 117, a right side 119, a first plurality of lower flaps 121 and 123, a second plurality of lower flaps 125 and 127, a first plurality of upper flaps 129 and 131, and a second plurality of upper flaps 132 and 134.
Front 113 and rear 115 may extend generally vertically and parallel to one another and may have substantially matching lengths and widths. Left side 117 and right side 119 may extend generally vertically and parallel to one another and may have substantially matching lengths and widths. Each of left side 117 and right side 119 may be generally perpendicular to each of front 113 and rear 115. The widths (i.e., heights) of front 113 and rear 115 may be greater than the widths (i.e., heights) of left side 117 and right side 119. For example, each of front 113 and rear 115 may have a width that is approximately 2 inches greater than the width of each of left side 117 and right side 119. The upper and lower edges of front 113 and rear 115 may be substantially aligned with one another, and the upper and lower edges of left side 117 and right side 119 may be substantially aligned with one another, with left side 117 and right side 119 having their respective upper and lower edges substantially equidistantly spaced from the respective upper and lower edges of front 113 and rear 115. In other words, the lower edges of front 113 and rear 115 may be spaced downwardly relative to the lower edges of left side 117 and right side 119, and the upper edges of front 113 and rear 115 may be spaced upwardly relative to the upper edges of left side 117 and right side 119. Consequently, where, for example, front 113 and rear 115 may have a width that is approximately 2 inches greater than the widths of left side 117 and right side 119, the upper edges of front 113 and rear 115 may extend approximately 1 inch above the upper edges of left side 117 and right side 119 to create an air gap of about 1 inch, and the lower edges of front 113 and rear 115 may extend approximately 1 inch below the lower edges of left side 117 and right side 119 to create an air gap of about 1 inch.
Front 113 may be integrally connected along its left vertical edge to left side 117 and may be integrally connected along its right vertical edge to right side 119. Rear 115 may be integrally connected along one vertical edge to left side 117 and may be joined to right side 119 using a panel 133. More specifically, panel 133 may be integrally connected along one vertical edge to rear 115 and may have its outer face secured to the inner face of right side 119 using an adhesive tape (not shown) or other suitable means.
Lower flap 121 may be integrally connected along its front edge to the lower edge of front 113 and may extend generally perpendicularly relative to front 113 (i.e., generally horizontally). Lower flap 123 may be integrally connected along its rear edge to the lower edge of rear 115 and may extend generally perpendicularly relative to rear 115 (i.e., generally horizontally). The rear edge of lower flap 121 and the front edge of lower flap 123 may be secured to one another using an adhesive tape 120 or other suitable means. (In the present embodiment, tape 120 is shown as transparent but need not be.)
Lower flap 125 may be integrally connected along its left edge to the lower edge of left side 117 and may extend generally perpendicularly relative to left side 117 (i.e., generally horizontally). Lower flap 127 may be integrally connected along its right edge to the lower edge of right side 119 and may extend generally perpendicularly relative to right side 119 (i.e., generally horizontally). The right edge of lower flap 125 and the left edge of lower flap 127 may be secured to one another using an adhesive tape 124 or other suitable means. (In the present embodiment, tape 124 is shown as transparent but need not be.) When secured to one another, flaps 125 and 127 may define the lower boundary of a product cavity 128 of product box 111. (In the present embodiment, product cavity 128 may be generally rectangular prismatic in shape but need not be.) A space 135 may be formed below flaps 125 and 127 and above flaps 121 and 123. Space 135, which may be filled with or contain air, may serve to thermally insulate, to a certain extent, the items in cavity 128 of product box 111 from a passive temperature-control member positioned below flaps 121 and 123. This may be advantageous, for example, in circumstances in which the passive temperature-control member, if sitting directly below a conventional product box, would cause the contents of the product box to become too cold. Consequently, such an approach may obviate the need to position materials, like bubble wrap, between the bottom of the product box and the passive temperature-control member to keep the contents of the product box from becoming too cold.
Upper flap 129 may be integrally connected along its front edge to the upper edge of front 113 and may extend generally perpendicularly relative to front 113 (i.e., generally horizontally). Upper flap 131 may be integrally connected along its rear edge to the upper edge of rear 115 and may extend generally perpendicularly relative to the rear 115 (i.e., generally horizontally). The rear edge of upper flap 129 and the front edge of upper flap 131 may be secured to one another using an adhesive tape 126 or other suitable means. (In the present embodiment, tape 126 is shown as transparent but need not be.)
Upper flap 132 may be integrally connected along its left edge to left side 117, and upper flap 134 may be integrally connected along its right edge to right side 119. Upper flap 132 may be folded to form an upper portion 137 extending inwardly from the upper edge of left side 117 and substantially perpendicular to left side 117, a middle portion 139 extending downwardly from the right edge of upper portion 137 and substantially perpendicular to upper portion 137, and a lower portion 141 extending outwardly from the bottom edge of middle portion 139 and substantially perpendicular to middle portion 139. As a result, left side 117 and upper flap 132 may jointly form a double-walled construction. Such a double-walled construction may be filled with or contain air and, in so doing, may form a chamber 142 that may serve to thermally insulate cavity 128 of product box 111.
In a similar manner, upper flap 134 may be folded to form an upper portion 143 extending inwardly from the upper edge of right side 119 and substantially perpendicular to right side 119, a middle portion 145 extending downwardly from the right edge of upper portion 143 and substantially perpendicular to upper portion 143, and a lower portion 147 extending outwardly from the bottom edge of middle portion 145 and substantially perpendicular to middle portion 145. As a result, right side 119 and upper flap 134 may jointly form a double-walled construction. Such a double-walled construction may be filled with or contain air and, in so doing, may form a chamber 144 that may serve to thermally insulate cavity 128 of product box 111.
Due, at least in part, to the fact that the upper edges of front 113 and rear 115 extend above left side 117 and right side 119, when upper flaps 129 and 131 are secured to one another, a space 150 may be formed above cavity 128 in the volume defined, in part, by flaps 129 and 131 and by flaps 132 and 134. Space 150, which may be filled with or contain air, may serve to thermally insulate, to a certain extent, items in product cavity 128 of product box 111 from a passive temperature-control member positioned on top of flaps 129 and 131. This may be advantageous, for example, in circumstances in which the passive temperature-control member, if sitting directly on top of a conventional product box, would cause the contents of the product box to become too cold. Consequently, such an approach may obviate the need to position materials, like bubble wrap, between the top of the product box and the passive temperature-control member to keep the contents of the product box from becoming too cold.
Product box 111 may further comprise a plurality of tabs or wings, a first wing 151 integrally connected to flap 129 and extending outwardly at the interface of front 113 and flap 129, a second wing 153 integrally connected to flap 131 and extending outwardly at the interface of rear 115 and flap 131, a third wing 155 integrally connected to flap 132 and extending outwardly at the interface of left side 117 and flap 132, and a fourth wing 157 integrally connected to flap 134 and extending outwardly at the interface of right side 119 and flap 134. Wings 151, 153, 155, and 157, which may be cut out from front 113, rear 115, left side 117, and right side 119, respectively, may be appropriately dimensioned to engage the inside surfaces of the front, rear, and side walls of an insulated container into which product box 111 may be positioned. This may allow air to circulate around product box 111, thereby minimizing temperature gradients around product box 111. According to one embodiment, wings, 151, 153, 155 and 157 may be dimensioned similarly to one another. In this manner, product box 111 may be generally centered relative to the vertical walls of the insulated container by wings 151, 153, 155 and 157.

Blank 251 may be appropriately dimensioned to make a product box having inner dimensions of 17 inches (length)×11 1/8 inches (width)×6 inches (depth). It is to be understood that these dimensions are merely exemplary.
Product box 111 may be used as a part of many different types of shipping systems and may be used to keep payloads within various target temperature ranges, such as, but not limited to, −20° C.±5° C. (frozen), +5° C.±3° C. (refrigerated), and +20° C.±5° C. (room temperature). For example, product box 111 may be disposed within the cavity of an insulated container (which may be made of, for example, expanded polystyrene or the like), which, in turn, may be disposed within an outer container made of, for example, corrugated cardboard or the like. One or more passive temperature-control members may also be positioned within the insulated container in contact with (or near) one or more outer surfaces of product box 111.

Product box 411 may comprise a front 413, a rear 415, a left side 417, a right side 419, a first plurality of lower flaps 421 and 423, a second plurality of lower flaps 425 and 427, a first plurality of upper flaps 429 and 431, and a second plurality of upper flaps 432 and 434.
Front 413 and rear 415 may extend generally vertically and parallel to one another and may have substantially matching lengths and widths. Left side 417 and right side 419 may extend generally vertically and parallel to one another and may have substantially matching lengths and widths. Each of left side 417 and right side 419 may be generally perpendicular to each of front 413 and rear 415. Moreover, the upper and lower edges of front 413, rear 415, left side 417, and right side 419 may be substantially aligned with one another. Consequently, product box 411 may differ from product boxes 11 and 111 in that product box 411 may have four lateral sides (i.e., front 413, rear 415, left side 417, and right side 419) of the same height whereas product boxes 11 and 111 may have two lateral sides that extend above and/or below the other two lateral sides.
Front 413 may be integrally connected along its left vertical edge to left side 417 and may be integrally connected along its right vertical edge to right side 419. Rear 415 may be integrally connected along one vertical edge to left side 417 and may be joined to right side 419 using a panel 433. More specifically, panel 433 may be integrally connected along one vertical edge to rear 415 and may have its outer face secured to the inner face of right side 419 using an adhesive tape (not shown) or other suitable means.
Lower flap 421 may be integrally connected along its front edge to the lower edge of front 413 and may extend generally perpendicularly relative to front 413 (i.e., generally horizontally). Lower flap 423 may be integrally connected along its rear edge to the lower edge of rear 415 and may extend generally perpendicularly relative to rear 415 (i.e., generally horizontally). The rear edge of lower flap 421 and the front edge of lower flap 423 may be secured to one another using an adhesive tape 420 or other suitable means. (In the present embodiment, tape 420 is shown as transparent but need not be.)
Lower flap 425 may be integrally connected along its left edge to the lower edge of left side 417 and may extend generally perpendicularly relative to left side 417. Lower flap 427 may be integrally connected along its right edge to the lower edge of right side 419 and may extend generally perpendicularly relative to right side 419. The right edge of lower flap 425 and the left edge of lower flap 427 may or may not be secured to one another using an adhesive tape or other suitable means. Flaps 425 and 427 may be positioned above flaps 421 and 423 and may define the lower boundary of a product cavity 428 of product box 411. As can be seen, in the present embodiment, product cavity 428 may be a generally rectangular prismatic cavity but need not be.
Upper flap 429 may be integrally connected along its front edge to the upper edge of front 413 and may extend generally perpendicularly relative to front 413. Upper flap 431 may be integrally connected along its rear edge to the upper edge of rear 415 and may extend generally perpendicularly relative to rear 415. The rear edge of upper flap 429 and the front edge of upper flap 431 may be secured to one another using an adhesive tape 426 or other suitable means. (In the present embodiment, tape 426 is shown as transparent but need not be.)
Upper flap 432 may be integrally connected along its left edge to left side 417 and may extend generally perpendicularly relative to left side 417. Upper flap 434 may be integrally connected along its right edge to right side 419 and may extend generally perpendicularly relative to right side 419. Upper flaps 432 and 434 may or may not be secured to one another using an adhesive tape or other suitable means. Flaps 432 and 434 may be positioned below flaps 429 and 431 and may define the upper boundary of product cavity 428.
Product box 411 may further comprise a plurality of tabs or wings, a first wing 451 integrally connected to flap 429 and extending outwardly at the interface of front 413 and flap 429, a second wing 453 integrally connected to flap 431 and extending outwardly at the interface of rear 415 and flap 431, a third wing 455 integrally connected to flap 432 and extending outwardly at the interface of left side 417 and flap 432, and a fourth wing 457 integrally connected to flap 434 and extending outwardly at the interface of right side 419 and flap 434. Wings 451, 453, 455, and 457, which may be cut out from front 413, rear 415, left side 417, and right side 419, respectively, may be appropriately dimensioned to engage the inner front, rear, and side walls of an insulated container into which product box 411 may be positioned and, in so doing, may space front 413, rear 415, left side 417, and right side 419 from the aforementioned walls of the insulated container. This may allow air to circulate around product box 411, thereby minimizing temperature gradients around product box 411. According to one embodiment, wings 451. 453, 455 and 457 may be dimensioned similarly to one another. In this manner, product box 411 may be generally centered relative to the vertical walls of the insulated container by wings 451, 453, 455 and 457.
As can be appreciated, one difference between product box 411 and product boxes 11 and 111 is that product box 411 does not provide for an air gap above, below or to a side of the product cavity.
Product box 411 may be used as a part of many different types of shipping systems and may be used to keep payloads within various target temperature ranges, such as, but not limited to, −20° C.±5° C. (frozen), +5° C.±3° C. (refrigerated), and +20° C.±5° C. (room temperature). For example, product box 411 may be disposed within the cavity of an insulated container (which may be made of, for example, expanded polystyrene or the like), which, in turn, may be disposed within an outer container made of, for example, corrugated cardboard or the like. One or more passive temperature-control members may also be positioned within the insulated container in contact with (or near) one or more outer surfaces of product box 411.

Shipping system 701, which may be used to maintain a payload (e.g., pharmaceuticals, biological materials, medical devices, foods, beverages, etc.) within a desired temperature range, such as between +2° C. and +8° C., when the ambient temperature outside of shipping system 701 is comparatively high (i.e., a summer packout), may comprise an outer container 703, an insulated base 705, an insulated lid 707, product box 11, and a plurality of gel packs 709-1 through 709-7.
Outer container 703 may comprise, for example, a conventional corrugated cardboard box or carton. Outer container 703 may comprise a rectangular prismatic cavity 715 bounded by a plurality of rectangular side walls 717-1 through 717-4, a plurality of bottom closure flaps (not shown), and a plurality of top closure flaps 719-1 through 719-4. Adhesive strips of tape or other closure means (not shown) may be used to retain, in a closed condition, the bottom closure flaps and top closure flaps 719-1 through 719-4.
Insulated base 705 and insulated lid 707 may be removably disposed within cavity 715 of outer container 703 and may be appropriately dimensioned to be snugly received within cavity 715. Insulated base 705 may be made of or comprise expanded polystyrene and/or any other suitable thermal insulating material(s) and may be molded to form a unitary structure comprising a bottom wall 721 and four generally vertical side walls 723-1 through 723-4. Insulated lid 707 may be a unitary structure and may be made of or comprise expanded polystyrene or any other suitable thermal insulating material(s). Insulated lid 707 may be removably mounted on top of insulated base 705, and insulated base 705 and insulated lid 707 may jointly define a cavity 725 of generally rectangular prismatic shape. Insulated base 705 and insulated lid 707 may comprise mating elements, such as complementary tongue 716 and groove 718 structures.
Product box 11 may be removably disposed within cavity 725 and may be seated directly on top of the interior surface of bottom wall 721. Insulated base 705 may be dimensioned relative to product box 11 so that one or more of wings 37, 39, 41 and 43 may be in contact with, or proximate to, one or more corresponding side walls 723-1 through 723-4; however, insulated base 705 need not be so dimensioned.
Gel packs 709-1 through 709-7 may be identical to one another and each may comprise a gelled phase-change material having a phase-change temperature of 0° C. encased in a polymer pouch. For example, each of gel packs 709-1 through 709-7 may be a 600 series KOOLIT® gel pack featuring a polymer ice gel from Cold Chain Technologies, LLC (Franklin, Mass.). In particular, each of gel packs 709-1 through 709-7 may be a 20.5 oz. gel pack of the aforementioned type, such as 620E KOOLIT® gel pack from Cold Chain Technologies, LLC; however, it is to be understood that the present invention is not limited to any particular type of phase-change material nor is it limited to the type of container therefor. Gel packs 709-1 through 709-4 may be removably disposed in the spaces between the four vertical walls of product box 11 and the four corresponding side walls 723-1 through 723-4 of insulated base 705. Gel packs 709-5 through 709-7 may be removably positioned in a single layer on top of product box 11.
In use, outer container 703, insulated base 705, insulated lid 707, and product box 11 may be preconditioned at +20° C.±5° C.; the payload may be preconditioned at +5° C.±3° C.; and gel packs 709-1 through 709-7 may be preconditioned at −20° C.±5° C. (Gel packs 709-1 through 709-7 are preferably moved from their preconditioning environment to a +20° C.±5° C. environment approximately 30 minutes prior to packout.) The payload may be loaded into product box 11, and product box 11 may be closed. If product box 11 and insulated base 705 are not already loaded into outer container 703, they may be so loaded. Gel packs 709-1 through 709-7 may then be placed on and around product box 11 as indicated above, insulated lid 707 may be placed on top of insulated base 705, and outer container 703 may be closed.

Shipping system 751, which may be used to maintain a payload (e.g., pharmaceuticals, biological materials, medical devices, foods, beverages, etc.) within a desired temperature range, such as between +2° C. and +8° C., when the ambient temperature outside of shipping system 751 is comparatively low (i.e., a winter packout), may comprise an outer container 753, an insulated base 755, an insulated lid 757, product box 11, and a plurality of gel packs 759-1 and 759-2.
Outer container 753 may be identical to outer container 703, insulated base 755 may be identical to insulated base 705, insulated lid 757 may be identical to insulated lid 707, and gel packs 759-1 and 759-2 may be identical to gel packs 709-1 through 709-7.
In use, outer container 753, insulated base 755, insulated lid 757, and product box 11 may be preconditioned at +20° C.±5° C.; the payload may be preconditioned at +5° C.±3° C.; and gel packs 759-1 and 759-2 may be preconditioned at −20° C.±5° C. (Gel packs 759-1 and 759-2 are preferably moved from their preconditioning environment to a +20° C.±5° C. environment approximately 30 minutes prior to packout.) The payload may be loaded into product box 11, and product box 11 may be closed. If product box 11 and insulated base 755 are not already loaded into outer container 753, they may be so loaded. Gel packs 759-1 and 759-2 may then be placed on top of product box 11, insulated lid 757 may be placed on top of insulated base 755, and outer container 753 may be closed.
As can be appreciated, systems 701 and 751 have many of the same types of components, the principal difference between the two systems being that system 701 utilizes seven gel packs (with a frozen gel pack being positioned along each of the four lateral sides of the product box and three frozen gel packs being positioned directly on top of the product box) whereas system 751 utilizes only two gel packs (with both frozen gel packs being positioned directly on top of the product box and no gel packs being positioned along the lateral sides of the product box). In view of the above, one could convert system 701 into system 751 simply by removing some of the gel packs. Alternatively, one could convert system 751 into system 701 by adding gel packs. Alternatively, one could provide a kit including all of the components needed to assemble either system 701 or system 751 and then could use such a kit to assemble system 701 or system 751 as desired.

The present invention provides a number of advantages over existing product boxes and systems using the same. For example, the presence of wings in at least some of the embodiments of the product box helps to keep the product box spaced away from one or more walls of a surrounding container, thereby enabling air to move around the product box and minimizing the presence of thermal gradients. In addition, the presence of an air space above and/or below the product cavity in at least some of the embodiments of the product box helps to keep items within the product cavity from being affected too much by a frozen gel pack or other phase-change material positioned directly on top of and/or under the product box.
The embodiments of the present invention described above are intended to be merely exemplary and those skilled in the art shall be able to make numerous variations and modifications to it without departing from the spirit of the present invention. All such variations and modifications are intended to be within the scope of the present invention as defined in the appended claims.
The present application claims the benefit under 35 U.S.C. 119(e) of U.S. Provisional Patent Application No. 62/994,599, inventor Henry R. Melchor, filed Mar. 25, 2020, the disclosure of which is incorporated herein by reference.
