Abstract

A temperature sensitive material is transported in an insulated container. The temperature sensitive material is enclosed in an insulated container comprising a double wall container. The container has a front wall a rear wall, two side walls, and a bottom wall, and insulation material in each of the regions between the double walls of said front wall, said rear wall, said two side walls, and the bottom wall. A double wall container cover has insulation material in the cover'"'"'s double walls. A releasable hinge is provided and the container cover is releasably secured to the double wall container. A temperature sensing system is provided for monitoring the temperature within the container. The monitored temperature is stored in a temperature history database.

U”

-shaped channel.

12. The insulated container of claim 11, further comprising hand holds formed in each of said flange regions.

13. The insulated container of claim 12, wherein said hand holds comprise openings in said flange regions and have a convex outwardly facing surface.

14.

15. The insulated container of claim 11, wherein said releasable hinge means comprises a cylindrical shaft member projecting inwardly from each of said flange regions, opposite sides of said, and a curved channel in, said curved channels being open at the lower edge of said cover, and extend toward the rear edge of said cover, and being closed at said rear edge, each cylindrical shaft member being mounted for rotary movement in said curved channel, and being removable from said curved recesses via the open end of said channel.

16. The insulated container of claim 14, further comprising means to snap said cylindrical shaft members in place at the rear edges of said flange regions.

17. The insulated container of claim 14, further comprising a locking member for locking said cover to said container, when said cover member is snapped in place at the rear edges of said flange regions, whereby said locking member precludes the cover from being removed from said container and prevents rotation of said cover about said releasable hinge.

18. The insulated container of claim 1, wherein the interior of said container has an interior ridge proximate the upper edge of the interior walls of said container, said ridge forming a longitudinal channel to receive an interior lid member, and hold said lid member in place, said lid member being a double wall member filled with a eutectic mixture.

19. The insulated container of claim 18, wherein said cover forms a rabbet joint with the open end of the walls of said insulated container.

20. The insulated container of claim 1, wherein said cover forms a rabbet joint with the open end of the walls of said insulated container.

21. The insulated container of claim 1, wherein said cover upper side and said container bottom wall have a mating recess and ridge, said recess and said ridge having asymmetrical configurations, whereby the cover of a first container mates with the bottom of another container in only one configuration, such that the front wall of said first container and the front wall of said another container, lie in the same plane.

22. The insulated container of claim 14, further comprising at least one flange on the upper surface of said cover, said at least one flange being positioned and dimensioned to extend into the rotational path of said cover and limit the degree of rotation of said cover about said cylindrical shaft member.
