Abstract: A container includes a substantially planar cover having a top surface, a lower portion and an upper portion. The container further includes a substantially planar base having a bottom surface, a lower portion, an upper portion, and a bottom wall. In addition, the container includes a flexible member joining the base and the cover for permitting the cover and the base to move relative to each between a joined position, defining a line of closure, and an opened position. The line of closure lies in a plane forming an angle with the bottom wall of between about 35° and about 60°.

Abstract: A method for recycling expanded polystyrene foam materials. Unexpanded virgin polystyrene beads having pentane gas contained therein are thermally expanded to produce a supply of expanded beads. Next, a supply of used expanded polystyrene foam is obtained and ground into small portions, preferably of the same size as the expanded beads. The used polystyrene foam pieces are then placed in contact with pentane gas. The expanded beads and the pentane-treated foam pieces are thereafter combined to form a mixture which preferably contains not less than about 50% by weight foam pieces. The mixture is then placed in a mold, followed by the application of heat and pressure thereto in order to produce a final product with a high degree of structural integrity. The pentane gas treatment of the foam pieces enables the fusion thereof to the expanded beads, resulting in a highly durable product.
