In the current embodiment, the second thermal liner 108 also contacts the inner box 104 at the left lateral side wall 170, the front lateral side wall 166, and the right lateral side wall 172. In various other embodiments, the liners 106, 108 may have any desired configuration such that together, the liners 106, 108 contact the respective side walls of the outer box 102 and inner box 104. The respective contact between the first thermal liner 106, second thermal liner 108, outer box 102, and inner box 104 is partially shown in FIG. 7.

FIG. 7 shows a cross-sectional view of the nested insulated packaging assembly 100 taken along line 7-7 in FIG. 6. As shown in FIG. 7, when the nested insulated packaging assembly 100 is fully closed, the locking panel 141 connected to the back flap 140 is at least partially inserted into the outer storage cavity 134 such that the locking panel 141 is adjacent to the front lateral side wall 116. FIG. 7 also shows the back flap 186 and first handle panel 190 folded over the front flap 188 and second handle panel 192 such that the back flap 186, first handle panel 190, front flap 188, and second handle panel 192 are orthogonal to the side walls 170, 172 of the inner box 104 in various embodiments.

In various embodiments, a user may desire to package items 704 at a first temperature in the nested insulated packaging assembly 100 and items 706 at a second temperature in the nested insulated packaging assembly 100. In various embodiments, the items 704 and items 706 may be various perishable items, pharmaceuticals, other temperature sensitive items, or other items to be shipped such as boxes of food, bottles of beverages, bagged fruits, bagged vegetables, and various other items. As shown in FIG. 7, the divider 110 is positioned in the inner storage cavity 182 of the inner box 104. The divider 110 divides the inner storage cavity 182 into an upper chamber 700 and a lower chamber 702. In various embodiments, the divider 110 may be mounted in the inner box 104 through various connecting mechanisms such as adhesives and glues, positioned on a ledge or flap of the inner surface of the inner box 104, rest on top of the items 704 in the lower chamber, or otherwise be positioned in the inner storage cavity 182 dividing the inner storage cavity into the upper chamber 700 and lower chamber 702.

In various embodiments, a combination of the first thermal liner 106, second thermal liner 108, and divider 110 maintain the lower chamber 702 at a first temperature suitable for the items 704 and maintain the upper chamber 700 at a second temperature suitable for the items 706. In various embodiments, the upper chamber 700 is maintained at a temperature above the temperature of the lower chamber 702. As described above, in various embodiments, the divider 110 includes vent openings 214 enabling fluid flow, typically air flow in various embodiments, through the divider 110. In various embodiments, warm air present in the lower chamber 702 may be vented to the upper chamber 700 through the vent openings 214. Venting of the warm air to the upper chamber 700 may keep the lower chamber 702 at a colder temperature for a longer duration because the divider 110 isolates the two temperature chambers. In this manner, co-shipment of items requiring dual temperatures is enabled.

Each of the upper chamber 700 and the lower chamber 702 may have customized temperature profiles. In various embodiments, the size, shape, and number of vent openings 214 may regulate the air flow through the divider 110 at desired levels to achieve specific temperature profiles in each of the upper chamber 700 and the lower chamber 702. In various embodiments, the insulation properties of the first thermal liner 106, second thermal liner 108, outer box 102, inner box 104, and divider 110 are also utilized to achieve specific temperature profiles in each of the upper chamber 700 and the lower chamber 702. As shown in FIG. 7, in various embodiments, the inner box 104 provides a physical barrier between the items 704, 706 to be shipped and the thermal liners 106, 108. In these embodiments, the thermal liners 106, 108 may not contact the items 704, 706 and the wear on the thermal liners 106, 108 from the items 704, 706, such as tearing, moisture, dirt, and other types of wear, is reduced.

The temperature profiles in each of the upper chamber 700 and lower chamber 702 may be controlled through location of a refrigerant in the outer box 102, location of a refrigerant in the inner box 104, the vent openings 214, the composition of the divider 110, the shape of the divider 110, and the insulation properties of the first thermal liner 106, second thermal liner 108, outer box 102, inner box 104, and divider 110. In various embodiments, the refrigerant may be selected from the group including, but not limited to, ice packs, dry ice, gel packs, chilling units, water, and various other mechanisms for keeping items chilled. In various embodiments, these aspects of the nested insulated packaging assembly 100 may be varied to obtain desired temperature profiles in each of the upper chamber 700 and lower chamber 702.
