Abstract

Abstract An angle edge guard for interposition between the interior of a shipping container and the exterior of an object being shipped is formed of two molded pulp walls having first edges joined to dispose the walls in substantially 90° relation when in place. The walls are indented at intervals up to a non-indented common ridge where the two walls join, leaving non-indented face ridges. The indentations form inwardly directed ribs defining therebetween a plurality of grooves including a deep corner groove in juxtaposition with the common ridge and side grooves in juxtaposition with the aforementioned face ridges and communicating with the corner groove.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 289 words
A unitary angle edge guard protector adapted for interposition between a substantially ninety degree interior corner of a shipping container and the exterior angle edge of an object being shipped, comprising: (a) a pair of generally flat molded pulp walls; (b) said walls being integrally joined by an arcuate portion and being in substantially ninety degree relation to one another when in place between said interior corner of a shipping container and a said exterior angle edge of an object being shipped; (c) each of said walls having an outwardly facing surface; (d) each of said walls having outwardly facing elongate leading edges; (e) each of said outwardly facing surface of said walls having a plurality of outwardly facing indentations at spaced intervals from a predetermined distance from said leading edge and a predetermined distance from said arcuate portion and normal to said leading edges; (f) said arcuate portion defining an inwardly facing elongate groove between said inwardly facing surface of said walls; (g) each of said inwardly facing surface of said walls having a plurality of inwardly facing indentations normal to said leading edges at spaced interals from a predetermined distance from said leading edge to said arcuate portion and integral with said elongate groove; (h) said inwardly facing indentations being joined by relatively flat planar surfaces and said planar surfaces being oppositely disposed to said outwardly facing indentations; (i) said outwardly facing indentations being joined by substantially rounded web surfaces and said rounded web surfaces being oppositely disposed to said inwardly facing indentations; (j) said walls including an angle of less than ninety degrees in a free, non-stressed condition, said walls being relatively movable around said elongate groove from the non-stressed condition to the ninety degree condition.
Claim 2
Dependent Claim 289 words
A unitary angle edge guard protector adapted for interposition between a substantially ninety degree interior corner of a shipping container and the exterior angle edge of an object being shipped, comprising: (a) a pair of generally flat molded pulp walls; (b) said walls being integrally joined by an arcuate portion and being in substantially ninety degree relation to one another when in place between said interior corner of a shipping container and a said exterior angle edge of an object being shipped; (c) each of said walls having an outwardly facing surface; (d) each of said walls having outwardly facing elongate leading edges; (e) each of said outwardly facing surface of said walls having a plurality of outwardly facing indentations at spaced intervals from a predetermined distance from said leading edge and a predetermined distance from said arcuate portion and normal to said leading edges; (f) said arcuate portion defining an inwardly facing elongate groove between said inwardly facing surface of said walls; (g) each of said inwardly facing surface of said walls having a plurality of inwardly facing indentations normal to said leading edges at spaced interals from a predetermined distance from said leading edge to said arcuate portion and integral with said elongate groove; (h) said inwardly facing indentations being joined by relatively flat planar surfaces and said planar surfaces being oppositely disposed to said outwardly facing indentations; (i) said outwardly facing indentations being joined by substantially rounded web surfaces and said rounded web surfaces being oppositely disposed to said inwardly facing indentations; (j) said walls including an angle of less than ninety degrees in a free, non-stressed condition, said walls being relatively movable around said elongate groove from the non-stressed condition to the ninety degree condition.
Claim 3
Dependent Claim 17 words
The angle edge guard according to claim 1 wherein said leading edges are bevelled upwardly and outwardly.
Claim 4
Dependent Claim 47 words
The angle edge guard according to claim 1 wherein said leading edges are substantially parallel to said elongate groove with the width of one of said walls being on the order of twice as wide between its first and second edges as the other of said walls.
