Abstract: 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.

Abstract: An insulated shipping container comprising box housing two identical L-shaped pieces attached at first and second junctions to form a right rectangular prism with a top open side and a bottom open side of identical dimensions to the top open side, a bottom piece aligned with the bottom open side of the right rectangular prism, and a top piece aligned with the top open side of the right rectangular prism. A merchant agent may assemble and pack the insulated shipping container with ice or other coolant material and one or more perishable items for shipment to a customer. The merchant agent may secure the insulated shipping container with tape and ship the one or more perishable items to a customer.

Abstract: A cruciform sheet including a rectangular central section bounded by two sections on each side substantially coextensive with the central section, and dimensioned to wrap around an egg carton. The sheet is bound at top and bottom by flaps, from which tabs extend. The flaps can be folded to cover a carton end, with the tabs inserted between the carton top and the folded side sections.

Abstract: An egg carton insert includes an N row by M column array of interconnected domes. Each dome is sized to enclose a top portion of an egg. Each dome is connected to each neighboring dome in the array. The array of domes forms an opening between each group of four adjacent domes. The array is arranged such that each dome corresponds to a dimple of an egg carton into which the insert can be placed. The overall dimensions of the egg carton insert are such that the egg carton can be closed when the insert is placed over one egg occupying each dimple of the egg carton.
