Delivering items to users by a delivery organization comprises a recyclable delivery container suitable to hold multiple items at different temperatures for the duration of the delivery. The delivery container may be a cube or a rectangular prism constructed of an insulating material. The delivery organization may position panels in the delivery container to separate two or three compartments of the delivery container, each compartment to be cooled to a different temperature than the others. The panels are constructed of an insulating material created by recyclable layers of cardboard and plastic. The delivery organization determines an appropriate coolant to cool all three compartments based on heat transfer requirements of the compartments and positions the coolant in the bottom of the first compartment. The items are placed in the appropriate compartments of the delivery container. Vents can be provided to relieve pressure created by the coolant.

1. A container assembly with multiple temperature compartments, comprising: a first set of container walls forming a bottom surface, four side walls, and a top surface;an insulating layer positioned inside the first set of container walls, the insulating layer being formed of alternating layers comprising at least one substrate layer and one plastic layer;a second set of container walls comprising a second set of container side walls, a top panel, and a second bottom surface, the second set of container walls being disposed inside the insulating layer;a coolant disposed inside the second set of container walls and relative to the second bottom surface, the coolant having cooling characteristics to maintain a temperature of items in a first compartment inside the second set of container walls at or below a first temperature for a period of time;a dividing panel positioned inside the second set of container walls and dividing the interior of the second set of container walls into the first compartment comprising the coolant and a second compartment, the dividing panel being constructed to allow a desired rate of heat transfer from the second compartment to the first compartment such that the temperature of items in the second compartment are at or below a second temperature that is different from the first temperature of the first compartment for a period of time,wherein the container assembly further comprises a third compartment formed outside the top panel of the second set of container walls, andwherein the bottom surface, the four side walls, and the top surface of the first set of container walls are sealed to enclose the container assembly. 2. The container assembly of claim 1, wherein the at least one substrate layer comprises corrugated cardboard. 3. The container assembly of claim 1, wherein the at least one plastic layer comprises a plastic bag. 4. The container assembly of claim 1, wherein the dividing panel separating the first compartment from the second compartment comprises a vent to allow air to flow between the first compartment and the second compartment. 5. The container assembly of claim 1, wherein the top panel of the second set of container walls that separates the second compartment from the third compartment comprises a vent to allow air to flow between the second compartment and the third compartment. 6. The container assembly of claim 1, wherein the top surface of the first set of container walls comprises a vent to allow air to flow from the third compartment to an area outside of the container assembly. 7. The container assembly of claim 1, wherein the container walls and the dividing panel are made from recyclable materials. 8. The container assembly of claim 1, wherein the insulating layer is made from recyclable materials. 9. The container assembly of claim 1, wherein the first set of container walls forms a rectangular prism. 10. The container assembly of claim 1, wherein the dividing panel is positioned such that the first compartment and the second compartment have different sizes. 11. The container assembly of claim 1, wherein the third compartment is formed inside the insulating layer. 12. The container assembly of claim 11, wherein the top panel of the second set of container walls is further constructed to allow a desired rate of heat transfer from the third compartment to the second compartment such that a temperature of items in the third compartment are at or below a third temperature that is different from the first temperature and the second temperature. 13. The container assembly of claim 1, wherein the coolant is dry ice. 14. The container assembly of claim 1, wherein the coolant is water ice. 15. The container assembly of claim 1, wherein the coolant is selected based on one or more of an ambient temperature; desired temperatures of the first, second, and third compartments; and an expected time for maintaining the first temperature and the second temperature at or below desired temperatures. 16. The container assembly of claim 1, wherein the first set of container walls comprises horizontal grooves therein, and wherein the dividing panel is placed into the horizontal grooves in the container walls such that the dividing panel is affixed to the container wall. 17. The container assembly of claim 1, wherein materials of the second set of container walls and the dividing panel are determined based on one or more of an ambient temperature; maintained temperatures of the first, second, and third compartments; and an expected time until delivery of the container assembly. 18. The container assembly of claim 1, wherein the second set of container walls comprise at least an outer plastic layer, a middle cardboard layer, and an inner plastic layer. 19. A method to assemble and pack a container assembly for cooling items, comprising: receiving a plurality of items, the items requiring at least three different temperatures for storage;selecting a first container with an outer container wall forming a top surface, a bottom surface and four side walls;positioning an insulating layer inside the first container, the insulating layer being formed of alternating layers comprising at least one substrate layer and one plastic layer;positioning a second container inside the insulating layer, the second container comprising a second set of container side walls, a bottom wall, and a top wall;depositing a coolant in the second container relative to the bottom wall, the coolant having cooling characteristics to maintain a temperature of items in a first compartment in the second container at or below a first temperature;positioning a dividing panel inside the second container to divide the interior of the second container into the first compartment comprising the coolant and a second compartment, the dividing panel being constructed to allow a desired rate of heat transfer from the second compartment to the first compartment such that the temperature of items in the second compartment are at or below a second temperature that is different from the first temperature;forming a third compartment, the third compartment formed outside the top panel of the second set of container walls, andwherein the bottom surface, the four side walls, and the top surface of the first set of container walls are sealed to enclose the container assembly. 20. The method of claim 19, wherein the at least one substrate layer comprises corrugated cardboard.
