- 1. A plastic pallet comprising:
- a substantially rectangular, substantially planar load bearing deck member formed from an upper sheet of thermoplastic material and a lower sheet of thermoplastic material;
- a first axis in the plane of said deck member extending through the center of said deck member running between two non-adjacent sides of said deck member;
- a second axis extending through the center of said deck member in the plane of the deck member perpendicular to said first axis;
- a plurality of generally non-linear bosses formed in said upper sheet of thermoplastic material depending downwardly to a predetermined depth defining a plurality of boss floors;
- a plurality of generally non-linear bosses formed in said lower sheet of thermoplastic material projecting upwardly to a predetermined depth and defining a plurality of boss ceilings;
- said upper and lower sheets of thermoplastic being fused at the intersection of said boss floors and said boss ceilings; and
- said bosses being arranged substantially non-symmetrically about one of said axes;
- said boss floors and said boss ceilings further comprising stepped boss ceilings to fuse with correspondingly stepped boss floors.
- 2. The pallet according to claim 1 wherein said bosses are further arranged substantially non-symmetrically about both said first and said second axes.
- 3. The pallet of claim 1 wherein said bosses further comprise a mixture of major bosses and minor bosses, said major bosses having a cross sectional area that is not equal to the cross sectional area of said minor bosses.
- 4. The pallet of claim 3 further comprising a plurality of upwardly opening feet depending downwardly from said deck and formed from said upper and lower sheets of thermoplastic being fused together.
- 5. A plastic pallet comprising:
- a substantially planar load bearing deck member formed from an upper and lower sheet of thermoplastic;
- a plurality of bosses thermoformed in said upper sheet and depending to define a plurality of boss floors, a plurality of bosses formed in the lower sheet and projecting to define a plurality of boss ceilings, the bosses arranged in a non-symmetrical, non-hinge forming arrangement and;
- a plurality of bosses thermoformed in said deck member whereby no more than three adjacent boss centers are colinear;
- said bosses being further arranged in substantially non-linear distributions;
- said boss floors and said boss ceilings further comprising stepped boss ceilings to fuse with correspondingly stepped boss floors.
