Molded pallet made of recycled materials
First Claim
1. A pallet system (10) which is compression molded from a mixture of recycled rubber and plastic materials,said pallet system (10) including a plurality of leg elements (11-19) extending from a top wall (60) thereof, said leg elements (11-19) being open-ended at a portion thereof (17a, 18a, 19a) to provide means whereby legs (71, 72, 73) of a lower pallet (70) may be inserted therein for increased racking strength, said pallet system (10) including vertical strengthing ribs (30) molded therein, said pallet system (10) including horizontal ribs (31) formed thereon, said pallet system (10) further including a plurality of diagonal ribs (40) formed thereon, said pallet system (10) including an outer reinforcing ridge (20) thereon with ribs (21) extending toward the pallet, wherein the the top wall (60) of said pallet includes anti-skid elements (61) formed thereon, wherein said diagonal ribs (40) are more closely spaced at lateral areas (47) and at central areas (45) of the pallet system to provide increased support between lateral legs and between central legs of the pallet system, wherein the mixture comprises EPDM, scrap from rubber seals or car parts, SBR at up to 50% by weight, EVA and ULDPE at 10-20% by weight, ATH fire retardant at 35% by weight in combination with 4% by weight zinc oxide and HDPE at 10-30% by weight, wherein the mixture is extruded and the extruded mass is placed into a water cooled compression mold to produce the desired pallet system in an economical manner.
