Abstract
Abstract A pallet is a unitized structure formed from a mixture of lignocellulose-containing fibers and a thermosetting bonding agent which is subjected to heat and pressure. The unit structure has conical feet and crosspieces which have integrated stacking members to permit the pallets to be stakced without damage to the stacking members and without jamming.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
133 words
A pallet having an upper side and a lower side and formed as a unitized structure which may be stacked with other such pallets when unloaded in a relatively small space without jamming or damage, the pallet being formed of a mixture of lignocellulose-containing fibers and a thermosetting bonding agent subjected to heat and pressure to form said unitized structure, said structure comprising several feet; crosspieces extending between the neighboring feet; and diagonal crosspieces, said diagonal crosspieces being formed with stacking members integral with said diagonal crosspieces, said stacking members being so formed that the length and width thereof on said lower side are larger than the length and width on said upper side whereby each of said stacking members forms a bearing surface on said lower side which is operative for stacking.
Claim 2
Dependent Claim
133 words

Claim 3
Dependent Claim
12 words
A pallet as defined in claim 1, wherein said crosspieces are trough-shaped.
Claim 4
Dependent Claim
17 words
A pallet as defined in claim 1, wherein said feet are conically shaped and are downwardly tapered.
Claim 5
Dependent Claim
30 words
A pallet as defined in claim 1, wherein said feet are uniformly spaced around the perimeter of said unitized structure and said crosspieces connect said feet in a grid-like manner.
Claim 6
Dependent Claim
40 words
A pallet as defined in claim 4, wherein said unitized structure further comprises a foot in the geometric center of said unitized structure and wherein said diagonal crosspieces emanate from said foot toward the respective corners of said unitized structure.
