Abstract

Abstract A molded, solid, high density, nesting pallet, for barrels or drums, having four-way entry, dimensioned to insure tine positioning of a fork-lift, vertically below the center of gravity of individual barrels or drums, or slightly outboard thereof, and providing a load-bearing surface for a symmetrical load of four barrels or drums on sites surrounded by a raised lip; and pallet legs having indentations positioned to register with flanged tops of barrels or drums upon which a loaded pallet may be stacked.

Claim 3
Dependent Claim 48 words
A pallet for barrels and drums comprising, (a) the device according to claim 1, (b) depressions at each corner of the sheet defining corner legs to support the load bearing surfaces, (c) depressions on the sheet spaced inwardly generally equidistant from the corner legs, and defining intermediate support-legs.
Claim 4
Dependent Claim 72 words
A pallet for barrels and drums comprising, (a) the device according to claim 2, (b) a middle, flat central area at the intersection of the four generally coequal sites on the top of the sheet, (c) a middle channel surrounding the middle flat central area, (d) a middle flat, intermediate, area surrounding the middle channel, (e) a continuous depression in the sheet surrounding the flat intermediate middle area defining a central support-leg.
Claim 5
Dependent Claim 58 words
A pallet for barrels and drums comprising, (a) the device according to claim 3, (b) the flat central area, the flat intermediate area, the flat outer area, the flat area defining a retaining rail, the middle flat central area, the middle flat intermediate area, all being generally coplanar with each other and together comprising a load bearing surface.
Claim 6
Dependent Claim 39 words
A pallet for barrels and drums comprising, (a) the device according to claim 2, (b) each of the spaces between each corner leg to each, intermediate support-leg being sufficiently narrow to closely receive a tine of a fork lift.
Claim 7
Dependent Claim 72 words
A pallet for barrels and drums comprising, (a) the device according to claim 5, (b) a center line of each site being in general registration with the center of the corresponding space between the adjacent corner leg and adjacent medial leg, whereby the center of gravity of a load on each site is in equilibrium with a tine of a fork lift intruded between a corner leg and an adjacent medial leg.
Claim 8
Dependent Claim 65 words
A pallet for barrels and drums comprising, (a) the device according to claim 2, (b) each leg having a floor, (c) a stacking channel in the bottom of each leg in general registration with the flat annular channel whereby a pallet may be stacked on a loaded pallet with the stacking channel engaged with the rim of the barrels and drums loaded on another pallet.
Claim 9
Dependent Claim 132 words
A pallet for barrels and drums comprising, (a) a generally rectangular sheet, (b) a flat central generally circular inner area, (c) an inner generally annular, bridged channel surrounding the flat central area, (d) a flat intermediate generally circular area surrounding the inner channel, (e) an outer generally annular, bridged channel surrounding the flat intermediate area, (f) a flat outer area surrounding the outer channel, (g) a flat shallow annular channel on a portion of the flat outer area, and defining a seat for portion of a flange on the bottom of a barrel or drum, (h) a flat outer area surrounding a portion of the flat annular shallow channel defining a retaining lip to position the bottom flange of a barrel or drum concentrically with respect to the flat central inner area.
Claim 10
Dependent Claim 132 words
A pallet for barrels and drums comprising, (a) a generally rectangular sheet, (b) a flat central generally circular inner area, (c) an inner generally annular, bridged channel surrounding the flat central area, (d) a flat intermediate generally circular area surrounding the inner channel, (e) an outer generally annular, bridged channel surrounding the flat intermediate area, (f) a flat outer area surrounding the outer channel, (g) a flat shallow annular channel on a portion of the flat outer area, and defining a seat for portion of a flange on the bottom of a barrel or drum, (h) a flat outer area surrounding a portion of the flat annular shallow channel defining a retaining lip to position the bottom flange of a barrel or drum concentrically with respect to the flat central inner area.
Claim 11
Dependent Claim 259 words
A pallet for barrels and drums comprising, (a) a generally flat, rigid rectangular molded plastic deck, (b) the deck divided into four sites, (c) a pair of concentric annular channels in each site, (d) integral bridges across each of the concentric annular channels dividing the channels into discontinuous arcuate segments; to strengthen the sheet against deformation for its full extent, from both ends to the other opposite ends, (e) shallow annular grooves concentric with each pair of annular channels on each site and having a diameter greater than each pair of channels, and dimensioned to receive the flange on the bottom of a barrel or drum, (f) a plurality of depressions in the plastic deck, deeper than the pairs of channels and defining legs to support the deck, (g) an annular channel in the deck at the center thereof at the intersection of the sites, (h) integral bridges in the deck across the annular channel at the center of the deck, (i) a depression at the center of the deck, surrounding the annular channel at the center of the deck, deeper than the central annular channel and defining a central leg, (j) the plurality of depressions, defining legs positioned: (A) one at each corner of the deck, and (B) at the edges of the deck, in pairs, spaced away from the legs at each corner, and (C) the spaces between the corner legs and the adjacent legs of each pair being sufficient to admit the tines of a fork lift at any of the four sides of the deck.
