Benefits of technology

[0007]An embodiment of the present invention includes a package defined by an outer container which contains one or more insulation panels and one or more PCM panels surrounding a payload cavity. In one example, a void or discontinuity can be defined at corners of the insulation panels and / or PCM panels through proper sizing of multiple panels. Such a void can be located at each corner or a smaller subset of corners. These voids can be defined for both the insulation panels and the PCM panels. One embodiment of the present invention utilizes multiple panels of identical form arranged in a particular pattern to define the voids.

Problems solved by technology

Prior passive thermal shipping containers are often unable to survive even modest drop tests.

Embodiment Construction

[0014]A phase change material is a substance with a high heat of fusion which, melting and solidifying at certain temperatures, is capable of storing or releasing large amounts of energy. Initially, solid-liquid phase change materials perform like conventional heat storage materials; their temperature rises as they absorb heat. Unlike conventional heat storage materials, however, when phase change materials reach a phase change temperature, i.e., melting point, they absorb large amounts of heat without a significant rise in temperature. When the ambient temperature around a liquid material falls, the phase change material cools and solidifies, releasing its stored latent heat. Certain phase change materials store 5 to 14 times more heat per unit volume than conventional heat storage materials such as iron, masonry, or rock.

[0015]Phase change materials can be broadly grouped into two categories: “Organic Compounds”, including but not limited to propylene and / or ethylene glycols and “...

Abstract

A shipping package for use in transportation of a temperature sensitive product. The shipping package includes layers of insulation and phase change material surrounding a payload cavity. The layers of insulation and phase change material are provided as separable panels. The panels may be inserted into an outer container in such manner that no insulation or phase change material are proximate to inner corners of the container. In one embodiment, the panels are provided in an overlapping relationship within the container so as to define corner discontinuities within the container.

Description

RELATED APPLICATIONS[0001]The application claims priority under 35 U.S.C. 119(e) from provisional U.S. Patent Application No. 60 / 973,981 filed Sep. 20, 2007, the contents of which are incorporated herein by reference.TECHNICAL FIELD[0002]The present disclosure is directed to a package for a temperature sensitive product and a method of use. More particularly, the disclosure relates to a package for shipping temperature sensitive materials having corner discontinuities provided by an insulation structure and / or a phase change material structure.BACKGROUND OF THE INVENTION[0003]Storing and transporting temperature sensitive materials in a passive container that is easy to assemble and has the smallest number of different components is desirable. Whereas various methods have been advanced for this purpose, prior known methods are designed to employ insulation and phase change material panels that extend into the three dimensional corners of the packages' individual layers.[0004]Shippin...
