Benefits of technology

[0006] The advantages of the container include those resulting from the first change material undergoing a phase change near the middle of the 2° to 8° C. range. This temperature range is the standard for shipping pharmaceutical, biological materials and food products. It is insulated (by a wall) from the ice in the first chamber and double-insulated (two walls) from the exterior, thereby minimizing the effects on the first phase change material of exterior temperature, and reducing the

Problems solved by technology

One drawback is that such phase change materials (such as alcohols as disclosed in U.

Example

[0010]FIG. 1 depicts a shipping container 10, inside a container 9, and having a payload chamber 12, and a series of first chambers 16. Ice (depicted in the form of gel packs 18) is placed in the first chambers 16. Individual containers 20 containing a first phase change material is placed in the payload chamber 12, which also houses a payload, preferably pharmaceuticals, food or a biological material. Two containers 20 are shown, but more may be used, with four (so that the payload is completely surrounded) being preferred. Suitable phase change materials include those that change solid to liquid in the range of 2° to 8° C. for example, decanol, and other materials including many set forth in US Patent No. 5,647,226: “Phase change apparatus for animal parts, human body parts, body fluids and culture” (incorporated by reference). It is also possible to use phase change materials outside this range for particular purposes, for example, dodecanol. Instead of ice it is possible to use ...

Abstract

Disclosed is a shipping container suitable for use for pharmaceuticals, biological materials, blood or tissues, or food products, having a double-walled multiple-chamber structure, wherein a first phase change material, with a phase change temperature between 2° to 8° C. (and in a preferred embodiment, 5°C.) in a payload chamber, and wherein the container includes one or more first chambers surrounding and sharing a wall with the payload chamber, and housing ice (or ice gel packs). A lid fits over (or is hinged to) the upper edges of the walls to seal the container and the payload.

Description

BACKGROUND OF THE INVENTION [0001] In the pharmaceutical, transplant and food industries, maintaining the temperature of shipped materials at refrigeration levels is necessary for proper preservation of the product. The temperature inside a shipping container can be actively maintained, for example, with a refrigeration unit, but passive regulation is preferred, due to decreased cost and the elimination of the need for a continuous power source during shipment. Any temperature regulation mechanism, however, should be suitable for use in a variety of weather and external temperature conditions, so that the customers do not have to purchase and then use several different passive regulation systems, which compensate for ambient temperature differences in shipment. With such systems, the customers would also be required to predict weather and shipping conditions. [0002] Passive regulation with conventional means, e.g., ice or ice “gel packs,” which keep the temperature near 0° C. cannot...
