A flexible bladder is enclosed within a plurality of overlapping plastic sheets, with the ends of the sheets being secured in place by the weight of the flexible bladder, when filled. The preferred plastic is an extruded, twin-walled, fluted plastic based upon a polypropylene copolymer. In a alternative embodiment, a pair of hexagonal, coaxial sleeves of the preferred plastic have an internal bladder for shipping materials. With both embodiments, hot chocolate is pumped into the bladder and cooled, in situ, to stop the chocolate from cooking further. The container is shipped, and then the chocolate is heated to facilitate pumping the chocolate out of the container. The cooling and heating processes involve the use of a heat exchange pad located between the bladder and the inner sleeve.

1. A container for shipping materials, comprising: an inner sleeve comprised of first and second sheets each comprised of five panels, the last panel of said first sheet overlapping the first panel of said second sheet and being heat-welded thereto and the first panel of said first sheet overlapping the last panel of said second sheet and being heat-welded thereto; an outer sleeve comprised of first and second sheets each comprised of five panels, the last panel of said first sheet overlapping the first panel of said second sheet and being heat-welded thereto, and the first panel of said first sheet overlapping the last panel of said second sheet and being heat-welded thereto, said inner and outer sleeves thus being configured as hexagonal sleeves, with the inner sleeve being snapped into place within the interior of the outer sleeve, and being oriented to have four triple wall sections, with the center point of each of the four sections being every 90° around the periphery of the inner and outer sleeve combined configuration; an hexagonal-shaped top member sized to fit over the top of the inner and outer sleeve configuration; and an hexagonal-shaped bottom member sized to fit within the bottom of the inner and outer sleeve configuration. 2. The container according to claim 1, wherein said inner sleeve, said outer sleeve, said top member and said bottom member are each comprised of extruded, twin-walled fluted plastic based upon a polypropylene copolymer. 3. The container according to claim 2, including in addition thereto, a flexible bladder located within the interior of the inner sleeve. 4. The container according to claim 3, including in addition thereto, at least one heat exchange pad located between the inner sleeve and the flexible bladder. 5. The container according to claim 3, including in addition thereto, a first fill port in the top member and a second fill port in the flexible bladder. 6. The container according to claim 3, including in addition thereto, a first discharge port in the lower portion of the outer sleeve, a second discharge port in the lower portion of the inner sleeve, and a third discharge port in the lower portion of the flexible bladder, and the first, second and third discharge ports are aligned for facilitating the pumping of the shipped materials out of the container.
