Insulated shipping container and method of making the same. In a preferred embodiment, the insulated shipping container comprises an outer box, an insulated insert, an inner box and a closure member. The outer box, which is preferably made of corrugated fiberboard, comprises a rectangular prismatic cavity bounded by a plurality of rectangular side walls, a closed bottom end, and top closure flaps. The insulated insert is snugly, but removably, disposed within the outer box and is shaped to define a rectangular prismatic cavity bounded by a bottom wall and a plurality of rectangular side walls, the insulated insert having an open top end. The insulated insert is made of a foamed polyurethane body to which on all sides, except its bottom, a thin, flexible, unfoamed polymer bag is integrally bonded. The bag is a unitary structure having a generally uniform rectangular shape, the bag being formed by sealing shut one end of a tubular member with a transverse seam and forming longitudinal creases extending from opposite ends of the seam. The inner box, which is snugly, but removably, disposed within the insert, is preferably made of corrugated fiberboard and is shaped to include a rectangular prismatic cavity bounded by a plurality of rectangular side walls and a closed bottom end, the top end thereof being open. The closure member is a thick piece of foam material snugly, but removably, disposed in the open end of the inner box.

The insulated shipping container as claimed in claim 1 wherein said inner box is made of a material selected from the group consisting of corrugated fiberboard and corrugated plastic.4. The insulated shipping container as claimed in claim 1 wherein each of said outer box and said inner box is made of a material selected from the group consisting of corrugated fiberboard and corrugated plastic.5. The insulated shipping container as claimed in claim 4 wherein said outer box is shaped to define a rectangular prismatic cavity bounded by four rectangular side wall, four top closure flaps and four bottom closure flaps.6. The insulated shipping container as claimed in claim 5 wherein said inner box is shaped to define a rectangular prismatic cavity bounded by four rectangular side walls and four bottom closure flaps, the top end of said inner box being open.7. The insulated shipping container as claimed in claim 1 wherein said flexible, un-foamed polymer bag is a unitary member having a transverse seam at said closed end thereof and a pair of longitudinal creases extending from opposite ends of said transverse seam.8. The insulated shipping container as claimed in claim 7 wherein said flexible, un-foamed polymer bag is formed by sealing one end of a generally tubular member to itself with a transverse seam and forming a pair of longitudinal creases on opposite ends of said transverse seam.9. The insulated shipping container as claimed in claim 7 wherein said flexible, un-foamed polymer bag is made of a material selected from the group consisting of hexene and polyethylene.10. The insulated shipping container as claimed in claim 1 wherein said inner box has an open top end, said insulated shipping container further comprising a closure member snugly, but removably, disposed within said open top end of said inner box.
