Abstract
Abstract A lightweight, completely recyclable paper pallet (10) is provided which can be produced, shipped and stored as two die cut pieces (24, 26), and which can be readily constructed without gluing to form a complete pallet (10). Preferably, the pallet (10) includes a planar main panel (12) having a pair of laterally spaced apart, side marginal, box-like underlying support sections (18, 20); a box-like central support section (22) coupled to the main panel (12) completes the construction. Interconnection of the marginal support sections (18, 20) and central support section (22) is accomplished by means of notched locking elements (106-120, 174-188) passing through strategically located slots (38-60) in main panel (12) and interfitting with upright notched reinforcing panels (70-84, 140-146) provided along the length of the supports (18, 20, 22).

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
246 words
A pallet adapted to lie upon a surface and support articles thereon, said pallet comprising: a body presenting an upper, article-supporting main panel presenting a pair opposed side margins and having a pair of underlying, marginal, support-defining sections joined to and extending from said opposed side margins, each of said support-defining sections including an upright end panel joined to and depending from a corresponding main panel side margin, a surface-engaging bottom panel generally parallel with said main panel and extending inwardly from said end panel, an upright connector panel extending upwardly from said bottom panel and generally parallel with said end panel, at least one upright reinforcing panel between said end and connector panels and extending upwardly from said bottom panel toward said main panel and transverse to said end and connector panels; and means for operatively maintaining each of said support sections beneath said main panel, said support section-maintaining means comprising structure defining two pairs of spaced apart slots through said main panel and respectively located proximal to a corresponding support section, structure defining a locking notch in the upper end of a reinforcing panel of each support section, there being an elongated, notched locking element extending from the upper surface of the connector panel of each support section, each of said locking elements extending through both of the slots of the corresponding pair thereof and downwardly for interlocking of the notch of each locking element and the locking notch of the corresponding reinforcing panel.
Claim 2
Dependent Claim
246 words
A pallet adapted to lie upon a surface and support articles thereon, said pallet comprising: a body presenting an upper, article-supporting main panel presenting a pair opposed side margins and having a pair of underlying, marginal, support-defining sections joined to and extending from said opposed side margins, each of said support-defining sections including an upright end panel joined to and depending from a corresponding main panel side margin, a surface-engaging bottom panel generally parallel with said main panel and extending inwardly from said end panel, an upright connector panel extending upwardly from said bottom panel and generally parallel with said end panel, at least one upright reinforcing panel between said end and connector panels and extending upwardly from said bottom panel toward said main panel and transverse to said end and connector panels; and means for operatively maintaining each of said support sections beneath said main panel, said support section-maintaining means comprising structure defining two pairs of spaced apart slots through said main panel and respectively located proximal to a corresponding support section, structure defining a locking notch in the upper end of a reinforcing panel of each support section, there being an elongated, notched locking element extending from the upper surface of the connector panel of each support section, each of said locking elements extending through both of the slots of the corresponding pair thereof and downwardly for interlocking of the notch of each locking element and the locking notch of the corresponding reinforcing panel.
Claim 3
Dependent Claim
31 words
The pallet of claim 1, wherein each of said support sections includes a plurality of said reinforcing panels extending along the length of said bottom panel and spaced from each other.
Claim 4
Dependent Claim
60 words
The pallet of claim 1, said body presenting, for each of said support-defining sections, three mutually parallel fold lines cooperatively presenting said end, bottom and connector panels, said reinforcing panel presenting top and side margins cut from said bottom panel, and a bottom margin secured to said bottom panel by a fold line transverse to said mutually parallel fold lines.
Claim 5
Dependent Claim
