Abstract
A novel molded structure especially useful as a rigid, load-bearing structure, is provided. Also provided is a novel process for molding the structure, which may be in the form of a pallet. By the process, the structure is chilled as it is being formed. Recycled resins including contaminants of limited compatibility may be used.
Claims12
A molded structure comprising a plurality of shaped hollows open to both outer surfaces of the structure, said shaped hollows being formed by outer surface-defining walls and a plurality of perpendicularly oriented ribs in structural connection with said walls, said shaped hollows having a relatively longer dimension of a certain thickness and a relatively shorter dimension of greater thickness than said certain thickness.
A pallet comprising
- a rigid, load-bearing platform having a rectangular shape and comprising a plurality of rectangular hollows open to both outer surfaces of said platform, said hollows being formed by outer surface-defining walls and a plurality of perpendicularly oriented ribs in structural connection with said walls, wherein a shorter dimension of said hollows is substantially thicker than a longer dimension of said hollows, and wherein said longer dimension is generally in alignment with the length of said platform.
