Definitions

  • This invention relates generally to large containers and their manufacture, and more particularly to a rotationally-molded intermodal shipping container.
  • Intermodal containers are hollow boxes made in standard sizes and provided with lifting eyes. These containers can easily be lifted, moved and secured so that they can be shipped by sea, air, or land. Intermodal containers are typically fabricated from steel and are therefore heavy, expensive, and prone to corrosion. There are also substantial costs involved in reshipping empty containers back to the point of origin, which often results in the empty containers being abandoned. It would be beneficial if such large containers could be made from substitute materials such as plastics, and furthermore if they could be easily recycled.
  • Rotational molding is one known process for producing hollow plastic products. Rotationally molded products have good strength and durability, and can achieve uniform wall thickness using relatively simple tooling. However, the required heating process is typically done by placing the mold inside an oven during the molding cycle. This would be prohibitively expensive and complex for large products such as intermodal containers.
  • a shipping container including: a plastic shell defining a closed volume; and at least one reinforcing beam disposed inside the closed volume.
  • the reinforcing beam includes an outer envelope, at least part of which is molded integrally with the shell.
  • an interior of the at least one reinforcing beam is filled with a strengthening material.
  • the strengthening material comprises isocyante foam.
  • the shell includes a floor, a roof, opposed side walls, and opposed end walls.
  • the floor has as least one floor beam integrally formed therein.
  • the shipping container includes at least one door for accessing an interior of the shell.

  • the beams are received in recesses defined in an exterior of the shell.
  • the external frame includes at least one corner lug which includes a lifting hole therein.
  • the shipping container further includes at least one door for accessing an interior of the shell.

  • each of the corner lugs includes at least one connector for attaching the corner lug to one of the beams.
  • a method of rotational molding a container includes providing a mold forming an enclosed volume in a preselected shape of a container, the mold being made of a heat- resistant, thermally conductive material; providing means for rotating the mold; charging the mold with a plastic material; directly heating the exterior of the mold so as to melt the plastic material by conduction; rotating the mold in at least two axes to distribute the plastic material in the mold; and allowing the plastic material to solidify inside the mold.
  • the direct heating is carried out using resistance heaters disposed on the mold.
  • a mold for making a container includes a plurality of heat-resistant, thermally conductive panels arranged to form an enclosed volume in a preselected shape of a container; and at least one heater attached to an outer surface of one of the panels.
  • the at least one heater is an electrical resistance heater.
  • the mold further includes a least one insert therein.
  • the insert has an outer envelope made of a heat-resistant, thermally conductive material, the envelope positioned within the mold to form a selected feature of a container; and a resistance heating element disposed in the interior of the outer envelope along its length.
  • At least some of the panels are pivotally connected to as to be able to selectively move from a closed position to an open position.

  • a method of using a container includes: providing a container including: a plastic shell defining a closed compartment of a first volume and an external frame comprising a plurality of elongated beams disposed around the shell to provide structural support to the shell; transporting the container to a first location; removing the external frame from the plastic shell; and rendering the plastic shell to a mass of plastic, the mass having a second volume substantially smaller than the first volume.
  • the method further includes shipping the external frame and the mass of plastic to a second location.
  • the mass is created by melting the plastic shell and forming it into a solid shape.
