MODULAR BOX ASSEMBLY

TECHNICAL FIELD

This disclosure relates to packaging. More specifically, this disclosure relates to a modular box assembly.

BACKGROUND

Packaging and shipping temperature sensitive contents can pose challenges. The contents can spoil, destabilize, freeze, melt, or evaporate during storage or shipping if the temperature of the contents is not maintained or the packaging is not protected from hot or cold environmental conditions. In applications such as hot food delivery, customers can be dissatisfied if the contents have cooled to ambient temperature upon delivery. Contents such as food, pharmaceuticals, electronics, or other temperature sensitive items can be damaged if exposed to temperature extremes. Many insulated packages are bulky and difficult to store prior to use. Additionally, many insulated packages are specialized to ship or carry hot goods, chilled goods, or frozen goods, and shippers must maintain large stocks of specialized packaging for each application. Additionally, many insulated packages cannot be recycled and are often disposed of in landfills.

However, before the present devices, systems, and/or methods are disclosed and described, it is to be understood that this disclosure is not limited to the specific devices, systems, and/or methods disclosed unless otherwise specified, and, as such, can, of course, vary. It is also to be understood that the terminology used herein is for the purpose of describing particular aspects only and is not intended to be limiting.

The following description is provided as an enabling teaching of the present devices, systems, and/or methods in its best, currently known aspect. To this end, those skilled in the relevant art will recognize and appreciate that many changes can be made to the various aspects of the present devices, systems, and/or methods described herein, while still obtaining the beneficial results of the present disclosure. It will also be apparent that some of the desired benefits of the present disclosure can be obtained by selecting some of the features of the present disclosure without utilizing other features. Accordingly, those who work in the art will recognize that many modifications and adaptations to the present disclosure are possible and can even be desirable in certain circumstances and are a part of the present disclosure. Thus, the following description is provided as illustrative of the principles of the present disclosure and not in limitation thereof.

As used throughout, the singular forms “a,” “an” and “the” include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to “an element” can include two or more such elements unless the context indicates otherwise.

Ranges can be expressed herein as from “about” one particular value, and/or to “about” another particular value. When such a range is expressed, another aspect includes from the one particular value and/or to the other particular value. Similarly, when values are expressed as approximations, by use of the antecedent “about,” it will be understood that the particular value forms another aspect. It will be further understood that the endpoints of each of the ranges are significant both in relation to the other endpoint, and independently of the other endpoint.

For purposes of the current disclosure, a material property or dimension measuring about X or substantially X on a particular measurement scale measures within a range between X plus an industry-standard upper tolerance for the specified measurement and X minus an industry-standard lower tolerance for the specified measurement. Because tolerances can vary between different materials, processes and between different models, the tolerance for a particular measurement of a particular component can fall within a range of tolerances.

As used herein, the terms “optional” or “optionally” mean that the subsequently described event or circumstance can or cannot occur, and that the description includes instances where said event or circumstance occurs and instances where it does not.

The word “or” as used herein means any one member of a particular list and also includes any combination of members of that list. Further, one should note that conditional language, such as, among others, “can,” “could,” “might,” or “may,” unless specifically stated otherwise, or otherwise understood within the context as used, is generally intended to convey that certain aspects include, while other aspects do not include, certain features, elements and/or steps. Thus, such conditional language is not generally intended to imply that features, elements and/or steps are in any way required for one or more particular aspects or that one or more particular aspects necessarily include logic for deciding, with or without user input or prompting, whether these features, elements and/or steps are included or are to be performed in any particular aspect.

Disclosed are components that can be used to perform the disclosed methods and systems. These and other components are disclosed herein, and it is understood that when combinations, subsets, interactions, groups, etc. of these components are disclosed that while specific reference of each various individual and collective combinations and permutation of these may not be explicitly disclosed, each is specifically contemplated and described herein, for all methods and systems. This applies to all aspects of this application including, but not limited to, steps in disclosed methods.

This configuration can provide full insulation or nearly full insulation over the width of the adjacent side panel 112a,b, 122a,b.

With the first side seam 356a and the second side seam 356b folded inwards, the first sheet 352 can be attached to the respective adjacent side panel 112a,b, 122a,b with an adhesive such as a glue, cement, epoxy, mastic, double-sided tape, cohesive, or other suitable material. A portion of the second sheet 354 extending between the first side seam 356a and the second side seam 356b can also be in facing contact with the adjacent side panel 112a,b, 122a,b and can optionally be attached with the adhesive. In other aspects, the insulated panels 130a-d may not comprise the second sheet 354, and either the insulation batt 350 can be in facing contact with the respective adjacent side panel 112a,b, 122a,b, or the first sheet 352 can fully encapsulate the insulation batt 350.

FIG. 4 is a cross-section of the modular box assembly 100 of FIG. 1 taken along line 4-4 shown in FIG. 2. In the present view, the carrying accessory 170 has been removed. The modular box assembly 100 can further comprise an insulated cavity panel 430 which can be disposed within the box cavity 206. The insulated cavity panel 430 can be constructed similar to the insulated panels 130a-d, 190; however, in the present aspect, the insulated cavity panel 430 can be a loose panel. The insulated portion 161 of the insulated cavity panel 430 can be shaped and sized complimentary to the horizontal cross-section of the box 101 in order to provide a close fit within the box cavity 206.

As shown, the insulated cavity panel 430 can divide the box cavity 206 into a first sub-compartment 406a and a second sub-compartment 406b. In the present aspect, the insulated cavity panel 430 can be horizontally oriented, and the first sub-compartment 406a can be an upper sub-compartment while the second sub-compartment 406b can be a lower sub-compartment. In other aspects, the insulated cavity panel 430 can be vertically oriented to divide the box cavity 206 into side-by-side compartments. In some aspects, the insulated box 110 can comprise multiple cavity panels 430 disposed within the box cavity 206 to divide the box cavity 206 into more than two compartments or no insulated cavity panels 430 so that the box cavity 206 is a single compartment. Dividing the box cavity 206 into sub-compartments can be desirable in order to package both hot and cold contents in the same insulated box 110 or other contents that should be stored at different temperatures.

In the present aspect, the bottom panel 306 can be uninsulated. Optionally, the insulated cavity panel 430 can be placed atop the bottom panel 306 to provide insulation for the bottom end 104 of the insulated box 110. In other aspects, the insulated box 110 can further comprise another insulated panel 130 (not shown) attached internally or externally to the bottom panel 306. In aspects in which the box top 190 can be uninsulated, the insulated cavity panel 430 can be positioned adjacent to the box top 190 to provide insulation for the top end 102 of the insulated box 110. In some aspects, the bottom panel 306 can be insulated and the insulated cavity panel 430 can be placed atop the bottom panel 306 in order to provide additional insulation for example. In some aspects, the modular box assembly 100 can comprise multiple insulated cavity panels 430 positioned within the box cavity 206. In other aspects, the modular box assembly 100 can comprise any or all of the insulated cavity panel 430, a bottom insulated panel 2130 (shown in FIG. 21), and a divider panel 2230 (shown in FIG. 22).

The bottom seam 156b and the top seam 156a of the border 158 of each insulated panel 130a-d can extend outwards from the perimeter 359 of the insulation batt 350 and the insulated portion 161. As previously discussed, the bottom seams 156b and the top seams 156a can be attached to the respective adjacent side panel 112a,b, 122a,b with the adhesive in order to secure the insulated panels 130a-d, to the box 101 proximate the top end 102 and the bottom end 104. In such aspects, the second sheet 354 can be attached to the adjacent side panel 112a,b, 122a,b, and the first sheet 352 may not contact the adjacent side panel 112a,b, 122a,b at the bottom seam 156b and the top seam 156a; however, the insulation batt 350 remains enclosed between the first sheet 352 and the adjacent side panel 112a,b, 122a,b. Optionally, portions of the second sheet 354 disposed between the top seams 156a and the bottom seam 156b can also be attached to the respective adjacent side panel 112a,b, 122a,b with the adhesive.

The outward extending top seams 156a can leave the lips 114a,b, 124a, b uninsulated; however, because the box top 190 rests below the box opening 106 on the shoulders 222a,b (should 222b shown in FIG. 3), the top end 102 of the insulated box 110 can remain fully insulated. Similarly, the bottom seams 156b can leave a portion of the side panels 112a,b, 122a,b proximate the bottom panel 306 uninsulated. However, in aspects in which the insulated cavity panel 430 can be positioned atop the bottom panel 306, the insulated cavity panel 430 can fully insulate the bottom end 104 of the insulated box 110. In other aspects, either or both of the bottom seams 156b and top seams 156a can be folded inward towards the insulation batt 350 and the insulated portion 161, and the insulation batt 350 can fully cover the height of the side panels 112a,b,122a,b.

The outwardly extended bottom seams 156b can define a bottom taper 458 extending around the insulated box 110 proximate the bottom end 104. The bottom taper 458 can cooperate with the lips 114a,b, 124a, b to securely stack multiple insulated boxes 110 on top of one another. The lips 114a, b, 124a,b of a lower insulated box of the stack of insulated boxes can deflect outwards allowing the bottom taper 458 of an upper insulated box to nest between the lips 114a,b, 124a,b and atop the box top 190 of the lower insulated box. By nesting between the lips 114a,b, 124a,b, the lips 114a,b, 124a,b can prevent the upper insulated box from sliding sideways off the top end 102 of the lower insulated box. The insulated boxes 110 can also be conveyable, such as on a conveyor belt, and the insulated boxes 110 can be rigid and strong enough to resist collapse on the conveyor belt. In other aspects, the lips 114a,b, 124a,b can be configured to be flush with the top panel 240 of the box top 190 when the box top 190 is in the closed position.

FIG. 5 is a perspective view of a method of manufacturing for an insulated panel 510. The method can apply to the manufacture of the insulated panels 130a-d, 140,430 or an insulation wrap 1730 (shown in FIG. 17). In a step 501, the insulation batt 350 can be positioned between the first sheet 352 and the second sheet 354. The first sheet 352 and the second sheet 354 can be sized and shaped complimentary to each other; however in some aspects, the sheets 352,354 can differ in size and shape. The insulation batt 350 and the sheets 352,354 can each be flat and substantially planar before assembly. In the present aspect, the insulation batt 350 can be approximately ⅜″ thick; however this thickness is not limiting. The thickness can range from 1/16″ to over 2″ with a preferred range of ¼″ to ½″. Also, as disclosed in at least one of the provisional applications incorporated by reference below, each batt used within the modular box assembly 100 may be of equal thickness, or may be of unequal thicknesses. A starting batt may be split longitudinally to provide two, three, or more partial thickness batts.

The first sheet 352 can define a first outer edge 552, and a portion of the first sheet 352 proximate the first outer edge 552 can define a first perimeter portion 542. The second sheet 354 can define a second outer edge 554, and a portion of the second sheet 354 proximate the second outer edge 554 can define a second perimeter portion 544. The sheets 352,354 can be sized to overhang the insulation batt 350 on all sides with the first perimeter portion 542 and the second perimeter portion 544 extending beyond the perimeter 359 of the insulation batt 350. The first perimeter portion 542 can encompass a first interior portion 536 of the first sheet 352, and the second perimeter portion 544 can encompass a second interior portion 538 of the second sheet 354. The interior portions 536,538 can be sized and shaped complimentary to the insulation batt 350.

Surfaces of the sheets 352,354 facing one another can be treated with an adhesive 530 such as a cohesive. In various aspects, the adhesive can be a glue, epoxy, cement, double-sided tape, or other suitable adhesive. The surfaces can be entirely treated with the adhesive 530 or selectively treated with the adhesive 530. In the aspect shown, the perimeter portions 542,544 can be selectively treated with the adhesive 530. In some aspects, the insulation batt 350 can also be adhered to the interior portions 536,538 of the sheets 352,354.

In a step 502, the sheets 352,354 can be aligned and positioned in facing engagement wherein the first perimeter portion 542 can be attached to the second perimeter portion 544 by the adhesive 530. The insulation batt 350 can be aligned between the interior portions 536,538. Attaching the perimeter portions 542,544 can form the border 158 of the insulated panel 510 around the perimeter 359 of the insulation batt 350. As depicted in step 502, the bottom seam 156b has been formed, the first side seam 356a and the second side seam 356b are partially formed, and the top seam 156a is yet to be formed.

The border 158 can seal the insulation batt 350 within the panel cavity 351 defined between the interior portions 536,538 of the sheets 352,354, respectively. Portions of the insulated panel 510 containing the insulation batt 350 can define the insulated portion 161 of the insulated panel 510. In some aspects, the insulation batt 350 can be aligned off-center from the sheets 352,354 wherein the border 158 can extend outwards further in some areas than others. In some aspects, the first side seam 356a, the second side seam 356b, the bottom seam 156b, and the top seam 156a can define different widths from one another. For example and without limitation, the first side seam 356a can extend outwards from the insulation batt 350 further than the bottom seam 156b or vice versa.

In a step 503, the first perimeter portion 542 has been fully attached to the second perimeter portion 544, thereby forming the completed border 158. Each of the first side seam 356a, the second side seam 356b, the bottom seam 156b, and the top seam 156a are fully formed. Manufacturing of the insulated panel 510 is thus completed; however in some aspects, the method can comprise additional steps such as cutting slots into the border 158. The border 158 can fully encapsulate the insulation batt 350 within the panel cavity 351; however in some aspects, the insulation batt 350 may not be fully encapsulated. In some aspects, the insulation batt 350 can define a complex shape which can comprise curves, notches, cutouts, or other features which can be reflected by complimentary shapes of the border 158 and the insulated portion 161.

In other aspects, the border 158 may not fully encompass and encapsulate the insulation batt 350. In some aspects, some portions of the perimeter 359 may be exposed at an unfinished side or a cutout of the border 158. In some aspects, the insulated panel 510 may not define the border 158 on any portion of the perimeter of the insulated panel 510, and the entire perimeter can define an unfinished edge. In such aspects, the insulated panel 510 can comprise pre-laminated paper and each of the sheets 352,354 can be attached in facing contact with the insulation batt 350 with, for example and without limitation, an adhesive. In some aspects in which the insulated panel 510 defines the border 158, the insulation batt 350 can also be attached in facing contact with one or both of the sheets 352,354. In some aspects, the pre-laminated paper can be provided in a roll, and the insulated panels 510 can be cut to size from the roll. In other aspects, the first sheet 352 and the second sheet 354 can be halves of a single sheet (not shown) which can be folded substantially in half. In such aspects, the insulation batt 350 can be encapsulated between the two halves of the single sheet. In other aspects, the second sheet 354 can be a board (not shown), such as a piece of cardboard, and the insulation batt 350 can be encapsulated between the first sheet 352 and the board.

In some aspects, the second sheet 354 can be a board 2154 (shown in FIG. 21). In such applications, the board 2154 can be rigid and the first sheet 352 can laminate and encapsulate the insulation batt 350 to the board 2154 to provide a rigid insulated panel, such as the bottom insulated panel 2130.

FIGS. 6A-C show perspective views of a method for attaching the insulated panel 130a to the side panel 122a. In FIG. 6A, the insulated panel 130a is shown partially attached to the side panel 122a. In the present aspect, the insulated panel 130a and the adjacent insulated panel 130b can be separate and isolated insulation panels 130 which are not connected together. By using separate insulated panels 130, manufacturing stress around corners of the insulated box 110 can be reduced during assembly of the insulated box 110, thereby reducing the likelihood of ripping or tearing the insulated panels 130 during assembly. The insulated panel 130a can be positioned adjacent to the side panel 122a, and the bottom seam 156b can be attached to a perimeter area 656 of the outer side surface 328a. The perimeter area 656 can extend around the edges of the side panel 122a. Specifically, the bottom seam 156b can be attached to a bottom portion (not shown) of the perimeter area 656 extending along the bottom end 104 of the side panel 122a. The perimeter area 656 can also define a first portion 658a and a second portion 658b extending upwards from the bottom portion towards a top portion 658c. The top portion 658c can extend along the lip 124a proximate the top end 102 of the side panel 122a.

The bottom seam 156b of the border 158 can extend outwards from the insulated portion 161 of the insulated panel 130a, and the second sheet 354 of the bottom seam 156b can be attached to the outer side surface 328a. In other aspects, the bottom seam 156b can be folded inwards towards the insulation batt 350 (not shown) encapsulated within the insulated portion 161. The bottom seam 156b can be attached in facing contact with the side panel 122a by an adhesive such as a glue, epoxy, cement, mastic, or any other suitable adhesive. In other aspects, the bottom seam 156b can be mechanically attached to the side panel 122a such as with a hook-and-loop fastener, stitching, or staples, or other suitable fasteners. In the present aspect, the first side seam 356a and the second side seam 356b (shown in FIG. 6B) can be folded inwards towards the insulation batt 350 (not shown) encapsulated within the insulated portion 161. The first side seam 356a can be attached to the bottom portion (not shown) at an intersection between the bottom portion and the first portion 658a of the perimeter area 656. The second side seam 356b can be attached to the bottom portion (not shown) at an intersection between the bottom portion and the second portion 658b of the perimeter area 656.

In FIG. 6B, the insulated panel 130a is shown with the bottom seam 156b attached to the side panel 122a, and the first side seam 356a and the second side seam 356b partially attached to the first portion 658a and the second portion 658b of the perimeter area 656, respectively. The first sheet 352 of the first side seam 356a and the second side seam 356b can be attached in facing contact to the perimeter portion 656 of the outer side surface 328a by an adhesive such as a glue, epoxy, cement, mastic, double-sided tape, cohesive, or other suitable adhesive. In other aspects, the first sheet 352 of the first side seam 356a and the second side seam 356b can be mechanically attached to the perimeter portion 656 of the outer side surface 328a, such as with a hook-and-loop fastener, stitching, or staples, or other suitable fasteners. In the aspect shown, the insulated panel 130a is shown as first attached proximate the bottom end 104 and then subsequently attached upwards along the first side seam 356a and the second side seam 356b towards the top end 102; however, this sequence and direction of attachment are not limiting. The insulated panel 130a can first be attached at the first side seam 356a, the second side seam 356b, or the top seam 156a and further attached in a sideways or downwards direction, or in any other suitable sequence. In some aspects, the second sheet 354 of the insulated portion 161 can also be attached to the outer side surface 328a by an adhesive such as a glue, epoxy, cement, mastic, or any other suitable adhesive.

FIG. 6C shows the insulated panel 130a completely attached to the side panel 122a. The first side seam 356a (shown in FIG. 6B) can be completely attached to the first portion 658a (shown in FIG. 6B) of the perimeter area 656 (shown in FIG. 6B) from the bottom end 104 to the top end 102. The second side seam 356b (shown in FIG. 6B) can be completely attached to the second portion 658b (shown in FIG. 6B) of the perimeter area 656 (shown in FIG. 6B) from the bottom end 104 to the top end 102. The top seam 156a can be fully attached to the top portion 658c (shown in FIG. 6B) by an adhesive such as a glue, epoxy, cement, mastic, double-sided tape, cohesive, or any other suitable adhesive. In other aspects, the top seam 156a can be mechanically attached to the top portion 658c, such as with a hook-and-loop fastener, staples, or stitching, or other suitable fasteners.

One method for attaching the insulated panel 130a to the side panel 122a shown in FIGS. 6A-C can apply to any of the insulated panels 130a-d, 140 and any of the adjacent panels 112a,b, 122a,b,240. The method can also be used to attach the insulated panels 130a-d to an inner surface, such as inner side surfaces 326a,b, within the box cavity 206. The method is demonstrated on the assembled box 101, and the method is exemplary and not limiting. The various panels 112a,b, 122a,b,306 of the box 101 can also be clad with individual insulated panels 130a-d prior to assembly of the box 101. For example, the insulated panels 130a-d, can be attached to the respective panels 112a,b, 122a,b of an unfolded box blank 710 (shown in FIG. 7). It can be desirable to attach the insulated panels 130a-d to the unfolded box blank 710 prior to assembly in order to reduce mechanical handling of the box 101. In another aspect, the insulated box 110 can be formed by wrapping the insulation wrap 1730 around the box 101 as described relative to FIG. 17.

FIG. 7 is a top view of the box blank 710 which can be assembled to form the box 101 of the insulated box 110. The box blank 710 can further define four corner fold lines 750a-d, such as a scored crease. In other aspects, the box blank 710 can define cuts in place of the corner fold lines 750a-d. A first corner fold line 750a can extend outwards from the bottom panel 306 to separate the first wing 312a from the second wing 324b. A second corner fold line 750b can extend outwards from the bottom panel 306 to separate the first wing 312b from the second wing 324d. A third corner fold line 750c can extend outwards from the bottom panel 306 to separate the first wing 312c from the second wing 324a. A fourth corner fold line 750d can extend outwards from the bottom panel 306 to separate the first wing 312d from the second wing 324c. In the present aspect, the adjacent wings 312a-d,324a-d can be hingedly connected by the corner fold lines 750a-d. In other aspects, the corner fold lines 750a-d can be cuts which separate the adjacent wings 312a-d,324a-d.

The box blank 710 can define a first length fold line 712a and a second length fold line 712b extending from the side panel 112a to the side panel 112b. The first length fold line 712a can facilitate folding of the first wing 312a relative to the side panel 112a, the side panel 122a relative to the bottom panel 306, and the first wing 312c relative to the second side panel 112b. The second length fold line 712b can facilitate folding of the first wing 312b relative to the side panel 112a, the side panel 122b relative to the bottom panel 306, and the first wing 312d relative to the side panel 112b.

The box blank 710 can further define a first width fold line 722a and a second width fold line 722b. The width fold lines 722a,b can be defined substantially perpendicular to the length fold lines 712a,b. The first width fold line 722a can facilitate folding of the second wing 324a relative to the side panel 122a, the side panel 112b relative to the bottom panel 306, and the second wing 324c relative to the side panel 122b. The second width fold line 722b can facilitate folding of the second wing 324b relative to the side panel 122a, the side panel 112a relative to the bottom panel 306, and the second wing 324d relative to the side panel 122b.

The center fold line 382 can extend across and bisect each side panel 112a,b. The center fold line 382 facilitates each of the side panels 112a,b folding inwards about the center fold line 382 and towards the bottom panel 306 to facilitate collapsing the insulated box 110 as shown in FIG. 8.

In some aspects, the insulated panels 130a-d can be attached to the side panels 112a,b, 122a,b to the unfolded box blank 710 prior to assembly. In other aspects, a single insulated panel 130a,b can be attached to the unfolded box blank 710 to cover the side panels 112a,b, 122a,b, and in some aspects, the bottom panel 306 as well. In some aspects, the entire unfolded box blank 710 can be covered by a single insulated panel.

FIG. 8 is a perspective view of the insulated box 110 of FIG. 1 in a collapsed configuration. In the present view, the carrying accessory 170 is removed to better show the details of the bottom panel 306. As the insulated box 110 collapses, the side panels 122a,b (side panels 122a,b shown in FIG. 1) move inwards together and towards one another, and the side panels 112a,b fold inwards towards one another (side panels 112a,b shown in FIG. 1). The V-shaped fold lines 386a-f (V-shaped fold lines 386e,f shown in FIG. 7) cooperate to transition the bottom panel 306 from a substantially planar shape to the truncated pyramidal shape. In the truncated pyramidal shape, the center subpanel 380 extends outwards and away from the side panels 112a,b and the side panels 122a,b (shown in FIG. 7). Exerting a force upon the center subpanel 380, such as by pushing the box 101 against the ground can cause the insulated box 110 to self-expand into an expanded configuration (shown in FIG. 1) with a substantially rectangular prism shape. The self-expanding action can be desirable to allow for quick and easy reconfiguration of the insulated box 110, unlike many boxes which must be folded and taped together. The insulated boxes 110 can be shipped and stored in the collapsed configuration for space-efficient packing, and a user can simply press upon the center subpanel 380, such as by pressing the center subpanel 380 against the ground, and the insulated box 110 can reconfigure to the expanded configuration.

FIG. 9 is a top view of the carrying accessory 170 of FIG. 1. As previously described, the carrying accessory 170 can be configured to extend beneath the insulated box 110 (shown in FIG. 1) to facilitate hand carrying of the insulated box 110. The carrying accessory 170 can define two pairs of fold lines 910a,b. A first pair of fold lines 910a can be defined between the first side portion 172a and the middle portion 180, and a second pair of fold lines 910b can be defined between the second side portion 172b and the middle portion 180. The fold lines of each pair of fold lines 910a,b can be placed closely together, such as an inch apart or less, and can be substantially parallel to one another. The pairs of fold lines 910a,b configure the carrying accessory 170 to closely conform to the bottom taper 458 (shown in FIG. 3) of the bottom end 104 of the insulated box 110. The middle portion 180 of the carrying accessory 170 can also define a pair of middle fold lines 912. The middle fold lines 912 can configure the carrying accessory 170 to closely conform to the truncated pyramidal shape of the bottom panel 306 (shown in FIG. 8) when the insulated box 110 is in the collapsed configuration as shown in FIG. 8. In other aspects each or any of the pairs of fold lines 910a,b and 912 can be substituted with single fold lines as desired.

FIG. 10 is a perspective view of the modular box assembly 100 comprising the insulated box 110 of FIG. 1 and another aspect of a box top 190 in accordance with another aspect of the present disclosure. In the present aspect, the box top 190 can be a tray top 1090. The tray top 1090 can comprise a top panel 1092 and four side panels, as represented by side panels 1094a,b, extending down from the top panel 1092. The tray top 1090 can be configured to fit over the top end 102 of the box 101 (shown in FIG. 1). The side panels 1094 can fit over the lips 114a,b, 124a,b (shown in FIG. 1) to enclose the box cavity 206 (shown in FIG. 2).

FIG. 11 is a perspective view of the modular box assembly 100 comprising the insulated box 110 of FIG. 1 and another aspect of a box top 190 in accordance with another aspect of the present disclosure. In the present aspect, the box top 190 can be a handle panel 1190. The handle top 1190 can comprise a top panel 1192 and a pair of side panels 1196a,b attached at opposite sides of the top panel 1192. In the present aspect, the top panel 1192 can be positioned between the lips 114a,b, 124a,b of the box 101, and the side panels 1196a,b can be positioned adjacent to the side panels 122a,b. The side panels 1196a,b can be hingedly attached to the top panel 1192. The handle top 1190 can further comprise a pair of side tabs 1396a,b (shown in FIG. 13) which can be attached to the top panel 1192 and which can extend downwards into the box cavity 206 (shown in FIG. 2), adjacent to the side panels 112a,b. In some aspects, the side tabs of the handle top 1190 can be glued to either the inside or the outside of the side panels 112a, b to secure the handle top 1190 to the insulated box 110. In other aspects, the handle top 1190 can be secured to the insulated box 110 by tape, banding, a strap, or other restraint mechanism.

A handle loop 1188a,b can be attached to each side panel 1196a,b, respectively, by a tape strip 1198a,b. In the present aspect, the tape strips 1198a,b can extend completely around the respective side panel 1196a,b to secure the handle loop 1188a,b to the side panel 1196a,b. In the present aspect, the handle loops 1188a,b can be rope loops. The handle loops 1188a,b can allow a user to carry the modular box assembly 100.

As described above, the inner box 1500 can be suspended within the box cavity 206, and the inner box 1500 can divide the box cavity 206 into a first sub-compartment 2106a and a second sub-compartment 2106b. In aspects in which the temperature maintaining material 2110 can be a cooling material, such as dry ice, the first sub-compartment 2106a can contain frozen goods, and the second sub-compartment 2106b can contain chilled goods. Dense, cold air from the temperature maintaining material 2110 can descend downwards from the temperature maintaining material 2110 through the vent holes 1612 (shown in FIG. 16) into the first sub-compartment 2106a to maintain a colder temperature in the first sub-compartment 2106a compared to the second sub-compartment 2106b.

In aspects in which the temperature maintaining material 2110 can be a heat emitting material, the second sub-compartment 2106b can maintain a temperature higher than the first sub-compartment 2106a due to rising hot air from the temperature maintaining material 2110. In such aspects, the inner box 1500 can be turned upside down with the center panel 1610 facing upwards to promote convection through the vent holes 1612 within the second sub-compartment 2106b. In some aspects, the insulated cavity panel 430 (shown in FIG. 4) can be placed beneath the handle top 1190 to resist heat transfer through the handle top 1190.

As shown, a portion of the first tape strip 1393a can attach to a portion of the second tape strip 2192a between the side panel 1196a and the top panel 1192 to form the living hinge 1310a of the handle top 1190. A portion of the first tape strip 1393b can attach to a portion of the second tape strip 2192b between the side panel 1196b and the top panel 1192 to form the living hinge 1310b.

In the present aspect, the modular box assembly 100 can further comprise the bottom insulated panel 2130. The bottom insulated panel 2130 can comprise a sheet 2152, a board 2154, and an insulation batt 2150. In the present aspect, the insulation batt 2150 can be encapsulated and laminated to the board 2154 by the sheet 2152. The sheet 2152 can comprise a thin, flexible material such as a film, a paper, a fabric, a mesh, or any other suitable material. The board 2154 can comprise a rigid material, such as cardboard, a plastic, a metal, a rigid foam, or any other suitable material. The bottom insulated panel 2130 can rest atop the bottom panel 306 of the box 101, and the bottom insulated panel 2130 can provide insulation for the bottom end 104 of the box 101.

The rigidity of the board 2154 can be desirable to prevent collapse of the box 101 or insulated box 110 during shipping or handling of the box 101 or insulated box 110. Collapse of one aspect of the insulated box 110 is demonstrated in FIG. 8. Inadvertent or accidental collapse of the box 101 or insulated box 110 during shipping or handling can crush or damage the contents of the box 101 or insulated box 110. By placing the board 2154 against the bottom panel 306, the rigidity of the board 2154 can prevent folding of the bottom panel 306 along the center fold line 382 (shown in FIG. 7), the corner fold lines 384a-d (shown in FIG. 7), and the V-shaped fold lines 386a-f (shown in FIG. 7), thereby preventing collapse of the insulated box 110 or box 101. In some applications, the board 2154, without the insulation batt 2150 and sheet 2152, can be placed atop the bottom panel 306 to prevent collapse as shown in FIG. 22.

FIG. 22 is a side cross-section of another aspect of the modular box assembly 100. In the present aspect, the modular box assembly 100 can comprise the handle top 1190 and the insulated box 110 of FIG. 17 which can be nested within the outer sleeve 1800 of FIG. 18. The modular box assembly 100 can further comprise the support brackets 1910 of FIG. 19 which can engage the shoulder channels 1922a,b of the box 101. The modular box assembly 100 can further comprise the divider panel 2230 which can be suspended within the box cavity 206 by the support brackets 1910.

The divider panel 2230 can comprise a first sheet 2252, a second sheet 2254, a pair of insulation batts 2250a,b, and a board 2256. In the present aspect, the board 2256 can be a rigid board; however in other aspects, the board 2256 can be a flexible or resilient board. The board 2256 can be positioned between the insulation batts 2250a,b, and the board 2256 and the insulation batts 2250a,b can be encapsulated between the first sheet 2252 and the second sheet 2254. The first sheet 2252 and the second sheet 2254 can be joined by a border 2258 which can extend around the divider panel 2230 to fully enclose the board 2256 and insulation batts 2250a,b. The divider panel 2230 can divide the box cavity 206 into a first sub-compartment 2206a and a second sub-compartment 2206b, and the divider panel 2230 can insulate the first sub-compartment 2206a from the second sub-compartment 2206b. The border 2258 can also form a seal with the box 101 to isolate the first sub-compartment 2206a from the second sub-compartment 2206b. In other aspects, the divider panel 2230 may not be suspended by the support brackets 1910 but can instead rest upon contents of the first sub-compartment 2206a, and the compressible nature of the lower insulation batt 2250b can allow the divider panel 2230 to conform to the contents of the first sub-compartment 2206a. The divider panel 2230 can provide increased rigidity compared to the insulated cavity panel 430 (shown in FIG. 4) which can be desirable for applications in which the divider panel 2230 supports a load.

In the present aspect, the modular box assembly 100 can further comprise a bag 2200 disposed within the second sub-compartment 2206b. In other aspects, the bag 2200 can be disposed within the first sub-compartment 2206a, or the bag 2200 can fill the box cavity 206 in undivided applications. In the present aspect, the bag 2200 can be sealed by a roll top seal 2204 to enclose a bag cavity 2202. In the present aspect, the bag 2200 can comprise a thermally reflective material or radiant barrier, such as a metal foil or a metalized plastic such as mylar, for example and without limitation. The bag 2200 can be configured to maintain higher or lower temperatures within the bag cavity 2202 relative to a temperature within the box cavity 206.

The modular box assembly 100 can further comprise temperature maintaining packs 2208 which can each comprise a temperature maintaining material 2210 enclosed in a container 2212. The temperature maintaining material 2210 can be similar to the temperature maintaining material 2110 (shown in FIG. 21), or the temperature maintaining material 2210 can comprise a different material than the temperature maintaining material 2110. The container 2212 can be a soft container such as a plastic bag, foil pack, fabric sack, or any other suitable soft container, or the container 2212 can be a hard container such as a plastic bottle, metal case, or any other suitable hard container.

The temperature maintaining packs 2208 can be configured to maintain higher or lower temperatures within the box cavity relative to an ambient temperature outside of the box cavity 206. For example, in cooling applications, the temperature maintaining material 2210 can absorb heat through a phase change such as melting ice or subliming dry ice, an endothermic reaction such as dissolving solid solute within a solvent, or warming of a chilled material, heat sink, or cold plate defining a temperature below the ambient temperature. In heating applications, the temperature maintaining material 2210 can release heat through a phase change such as condensation or solidification, an exothermic reaction such as oxidation or solid crystal nucleation in a supersaturated solution, or cooling of a heated material or heat source defining a temperature above the ambient temperature.

The temperature maintaining packs 2208 can be sized and shaped to cover the board 2154 or the bottom panel 306 of the box 101, similar to bricks, to form a first layer. In other aspects, an insulated panel, such as the insulated cavity panel 430 or the bottom insulated panel 2130 can be placed between the temperature maintaining packs 2208 and the bottom panel 306 to reduce heat transfer through the bottom end 104 of the box 101. Contents of the box 101 can be placed atop the temperature maintaining packs 2208, or in some aspects, another layer of temperature maintaining packs 2208 can be placed atop the first layer of temperature maintaining packs 2208 to provide increased heating or cooling time for contents of the box cavity 206. The temperature maintaining packs 2208 can be placed in both or either of the first sub-compartment 2206a and the second sub-compartment 2206b or in undivided applications, the temperature maintaining packs 2208 can be placed anywhere within the box cavity 206. In some aspects, the temperature maintaining packs 2208 can be used in the same box cavity 206 with the inner box 1500 and the temperature maintaining material 2110, for example and without limitation, to provide increased heating or cooling time for contents of the box cavity 260.

FIG. 23 is an exploded perspective view of another aspect of the insulated box 110 in accordance with another aspect of the present disclosure. The insulated box 110 of the present aspect can be an internally insulated box. The insulated box 110 can comprise an A-B liner 2310 which can comprise a first liner 2312a and a second liner 2312b.

A pair of side border portions 2322a,b of the border 158 can be defined by the side panels 2316a,b and the center panel 2314a, and the side border portions 2322a,b can extend between the respective end border portions 2320a,b.

The second liner 2312b can define a center panel 2314b disposed between a first side panel 2316c and a second side panel 2316d. A border 158 of the second liner 2312b can comprise a first end border portion 2320c defined by the first side panel 2316c and a second end border portion 2320d defined by the second side panel 2316d and disposed opposite from the first end border portion 2320c. A fold 2318c can be defined between the first side panel 2316c and the center panel 2314b, and a fold 2318d can be defined between the second side panel 2316d and the center panel 2314b. A pair of side border portions 2322c,d of the border 158 can be defined by the side panels 2316c,d and the center panel 2314b, and the side border portions 2322c,d can extend between the respective end border portions 2320c,d.

The liners 2312a,b can fit together to define a substantially cubic or rectangular prism shape with an inner insulated cavity (not shown) defined by the A-B liner 2310. The end border portions 2320a,b of the border 158 of the first liner 2312a can contact the center panel 2314b of the second liner 2312b, and the end border portions 2320c,d of the border 158 of the second liner 2312b can contact the center panel 2314a of the first liner 2312a. The side border portions 2322c, d of the border 158 of the second liner 2312b can each extend around the sides of a different one of the side panels 2316a,b. The side border portions 2322a,b of the border 158 of the first liner 2312a can each extend around the sides of a different one of the side panels 2316c,d.

In the present aspect, the A-B liner 2310 can be oriented so that the center panel 2314a of the first liner 2312a covers the box opening 106 of the box 101, the center panel 2314b of the second liner 2312b covers the bottom panel 306, and the side panels 2316a,b,c,d cover the side panels 112a,b, 122a,b of the box 101. In the present aspect, the side panels 2316a,b can cover the side panels 122a,b, and the side panels 2316c,d can cover the side panels 112a,b. In other aspects, the side panels 2316a,b can cover the side panels 112a,b, and the side panels 2316c,d can cover the side panels 122a,b.

In still other aspects, the A-B liner 2310 can be orientated such that the first side panel 2316a of the first liner 2312a covers the box opening 106, and the second side panel 2316b of the first liner 2312a covers the bottom panel 306 of the box 101. The side panels 112a,b, 122a,b of the box 101 can be covered by the second liner 2312b and the center panel 2314a of the first liner 2312a. Such a configuration can be desirable because the first side panel 2316a can act as a lid which can be folded about the fold 2318a to open and close the inner insulated cavity of the A-B Liner 2310 without requiring removal of either of the liners 2312a,b from the box 101.

In the present aspect, the sheets 352,354,2052,2054,2152,2252,2254 can comprise paper, such as kraft paper; however, in other embodiments, the sheets can comprise posterboard, cardboard, plastic sheeting, cellulose film, cloth, or any other suitable material. In some aspects, the sheets can comprise a water-proof or water-resistant material, such as water-proof paper. In some aspects, a one of the sheets 352,354,2052,2054,2152,2252,2254 of the modular box assembly 100 can comprised a material different from another of the sheets 352,354,2052,2054,2152,2252,2254. In the present aspect, the box 101 can comprise a paper fiber-based material such as corrugated cardboard or poster board; however, the box 101 can comprise any suitable rigid board material such as wood, plastic, metal, or any other material.

The insulation batts 350,2051,2150,2250a,b can comprise paper or other paper fiber materials; however, in other aspects, the insulation batts can comprise cotton, foam, rubber, plastics, fiberglass, mineral wool, or any other flexible insulation material. In the present application, the insulation batts can be repulpable. In the present aspect, the modular box assembly 100 can be 100% recyclable. In the present aspect, the modular box assembly 100 can be single-stream recyclable wherein all materials comprised by the modular box assembly 100 can be recycled by a single processing train without requiring separation of any materials or components of the modular box assembly 100. In the present aspect, the modular box assembly 100 can be compostable. In the present aspect, the modular box assembly 100 can be repulpable. In the present aspect, the modular box assembly 100 and each of the insulated box 110, the top panel 190, the insulated panels 130a-d,430,140,510, the insulation wrap 1730, the bottom insulated panel 2130, the divider panel 2230, and the liners 2312a,b can be repulpable in accordance with the requirements of the Aug. 16, 2013, revision of the “Voluntary Standard For Repulping and Recycling Corrugated Fiberboard Treated to Improve Its Performance in the Presence of Water and Water Vapor” provided by the Fibre Box Association of Elk Grove Village, IL which is hereby incorporated in its entirety. In the present aspect, the modular box assembly 100 and each of the insulated box 110, the top panel 190, the insulated panels 130a-d,430,140,510, the insulation wrap 1730, the bottom insulated panel 2130, the divider panel 2230, and the liners 2312a,b can be recyclable in accordance with the requirements of the Aug. 16, 2013, revision of the “Voluntary Standard For Repulping and Recycling Corrugated Fiberboard Treated to Improve Its Performance in the Presence of Water and Water Vapor” provided by the Fibre Box Association of Elk Grove Village, IL.

Recyclable and repulpable insulation materials are further described in U.S. Provisional Patent Application No. 62/375,555, filed Aug. 16, 2016, U.S. Provisional Patent Application No. 62/419,894, filed Nov. 9, 2016, and U.S. Provisional Patent Application No. 62/437,365, filed Dec. 21, 2016, which are each incorporated by reference in their entirety herein.

Further regarding the manufacture and composition of the insulation batts 350,2051,2150,2250a,b, one or more of the three above-identified applications, such as U.S. Provisional Patent Application No. 62/375,555, disclose that insulative pads/batts can be manufactured fiber compositions formed by passing recycled cardboard through a mill such as a hammer mill. Optionally, the batts may also be formed from a randomly distributed mixture of reinforcement fibers comprising natural fibers, such as cotton, and binder fibers having a length between 1/16 inch to 1.5 inches and a denier of between 5 and 12. The binder fibers, along with the reinforcement fibers, can be laid randomly yet consistently in x-y-z axes. The reinforcement fibers are generally bound together by heating the binder fibers above their glass transition temperature. As disclosed in U.S. Provisional Patent Applications Nos. 62/419,894 and 62/437,365, what have heretofore been described as reinforcement fibers may also comprise a mixture of recycled cardboard and paper fibers, ranging from and including a 50/50 cardboard/paper mix to and including a 75/25 cardboard/paper mix. The batt material using such reinforcement fibers can comprise 75% cardboard/paper mixture and 25% binder fiber, such batt material having a density of 1600 grams per square meter (“GSM”). Additional materials constructed are 80/20 at 1500 GSM; 80/20 at 1400 GSM; 85/15 at 1600 GSM; 85/15 at 1500 GSM; 85/15 at 1400 GSM; and 90/10 at 1500 GSM, with the first number being the paper/cardboard fiber mixture percentage and second number being a binder fiber percentage (for example, 80/20 is 80% paper/cardboard fiber mixture and 20% binder fiber).

As disclosed in at least U.S. Provisional Patent Application No. 62/375,555, typically, less than about 20% by weight binder fiber is used to form the insulation batts 350,2051,2150,2250a,b. The binder fibers are preferably thermoplastic fibers selected from the group containing polyethylene, polyester or polypropylene, or mixtures thereof. As further disclosed in U.S. Provisional Patent Applications Nos. 62/419,894 and 62/437,365, the binder fibers may also comprise water soluble and recyclable polyvinyl alcohol (“PVOH”), as well as mixtures of PVOH with any of the aforementioned binder fiber materials. The fiber can be for example a KURALON (tm) brand short cut fibers. As a binder fiber, the recyclable PVOH fiber used in the insulation can be a 0.4 to 1.0 denier fiber having a length of 3.0-4.0 mm. As still further disclosed in U.S. Provisional Patent Application No. 62/437,365, the binder fiber may be a bi-component fiber comprising polyethylene (“PE”) and polypropylene (“PP”). The PE/PP ratio of this bi-component fiber can range between 50/50 and about 65/35, or it may have the 65/35 PE/PP ratio. Such bi-component fibers may be available under the name ES FIBERVISIONS®, including under product codes EAC, EPS, ESC, ESE, EDC, Herculon T426, and Herculon T457. The binder fibers may also be constructed of recyclable or biodegradable material. The thermoplastic binder fibers may have a weight of less than 0.2 pounds per square foot and, more particularly, preferably about 0.1875 pounds per square foot. The remaining reinforcement fiber may be greater than 0.8 pounds per square foot, and preferably 1.0625 pounds per square foot.

Also as disclosed in at least U.S. Provisional Patent Application No. 62/375,555, the material comprising batts 350,2051,2150,2250a,b is heated in an oven to a temperature greater than about 350° F. and, more preferably, to a temperature of about 362° F. Such heating causes the binder fibers to melt and couple to the non-binder fibers, thus causing fibers to adhere to each other and solidify during cooling. Upon cooling, the binder fibers solidify and function to couple the non-binder reinforcement fibers together as well as function as reinforcement themselves.

The modular box assembly 100 can be used in applications in which a user or mail carrier transports perishable or temperature-sensitive goods, such as frozen, chilled, or hot goods. For example and without limitation, the modular box assembly 100 can be used to transport groceries, medications, electronics, or any other goods. The modular box assembly 100 can improve upon a common cardboard box by providing insulation to prevent spoilage of the contents. The modular box assembly 100 can also be used to deliver hot goods, such as warm foods.

In order to ship temperature-sensitive goods, common cardboard boxes are often packed with insulating materials made of plastics or foams which are not accepted by many recycling facilities or curb-side recycling programs in which a waste management service collects recyclables at a user's home. Consequently, shipping temperature-sensitive goods often produces non-recyclable waste which is deposited in landfills. The insulation materials often decompose very slowly, sometimes over the course of several centuries. In some instances, non-recyclable and non-biodegradable insulating materials can enter the oceans where the insulation materials can remain for years and harm marine life. In some aspects, the modular box assembly 100 can reduce waste and pollution by comprising materials which are recyclable or biodegradable. In aspects in which the modular box assembly 100 is curb-side or single-stream recyclable, the user may be more likely to recycle the modular box assembly 100 due to the ease of curb-side collection.
