Abstract
The present invention relates to a box system for keeping medicine and other payloads at a desired temperature for prolonged periods of time. The system generally includes three or more insulating materials between a refrigerant and the payload so that the payload is not cold-shocked by the refrigerant but instead maintains a desired temperature range during shipment. An advantage of the box system of certain embodiments of the present disclosure is that the system allows a shipper to use a temperature controlled system that is effective in controlling temperature without the need for any expensive phase change materials. A box having foldable tabs for securing the materials to each other is also disclosed herein.
Claims24
A container system comprising:
- a) a first outer container having an exterior, an interior, a bottom, at least one side extending upwardly from the bottom, and a lid opposite said first outer container bottom, said first outer container comprised of an insulating material other than cardboard;
- b) an inner container disposed in said first outer container interior and comprising an interior, an exterior, a bottom, at least one side extending upwardly from the inner container bottom, and a removable lid opposite said inner container bottom, said inner container bottom and said at least one side of said inner container comprising an outer layer comprising cardboard, a first middle layer interior to said outer layer and comprising a first insulating material other than cardboard, and an inner layer comprising cardboard, said inner layer interior to said outer layer and said first middle layer, wherein said first insulating material other than cardboard of at least one of said inner container bottom and said at least one side of said inner container comprises liquid water having an inner layer water temperature of at least about 10 degrees Celsius;
- c) a payload disposed in said inner container interior;
- and
- d) at least one refrigerant container comprising water-based refrigerant spaced about said first outer container interior, said at least one refrigerant container exterior to said inner container, said water-based refrigerant having a refrigerant temperature, said refrigerant temperature less than said inner layer water temperature.
