Abstract
Abstract A molded pulp corner protector adapted for insertion between shipping cartons and furniture comprises three triangular-shaped walls joined for defining a hollow article of pyramidal exterior form. The article walls are indented at regular intervals to provide a plurality of inwardly directed ribs which extend from the base edges of the article, substantially up to the slanting three corner edges of the pyramid. The inwardly directed ribs define a plurality of grooves including three inner corner grooves communicating at an inner apex, and side grooves which communicate with the corner grooves. The article is truncated at the lower corners such that the corner grooves also communicate with the exterior of the article.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
214 words
A unitary corner protector adapted for interposition between the corner of a shipping container and an object being shipped, comprising: three triangular-shaped, molded pulp walls, each of which is joined along first and second edges to matching edges of two remaining walls disposed at right angles to the first and to each other, wherein said walls meet at a common apex at the juncture of first and second edges of each said wall for defining a hollow article of pyramidal exterior form having a triangular base opening between third edges of said walls, said walls being indented, at intervals, from the third wall edges substantially up to the first and second wall edges forming a plurality of inwardly directed ribs extending substantially upwardly from the respective third edges of said walls, leaving nonindented first and second wall edges joined to third wall edges by nonindented face ridges located between said ribs for completing an outer truss-like face for each said wall, said inwardly directed ribs defining therebetween a plurality of grooves on the interior of said article including three inner corner grooves communicating at the inner apex of the article, and side grooves, in juxtaposition with said face ridges, communicating with the said corner grooves, said ribs extending substantially up to said corner grooves.
Claim 2
Dependent Claim
214 words
A unitary corner protector adapted for interposition between the corner of a shipping container and an object being shipped, comprising: three triangular-shaped, molded pulp walls, each of which is joined along first and second edges to matching edges of two remaining walls disposed at right angles to the first and to each other, wherein said walls meet at a common apex at the juncture of first and second edges of each said wall for defining a hollow article of pyramidal exterior form having a triangular base opening between third edges of said walls, said walls being indented, at intervals, from the third wall edges substantially up to the first and second wall edges forming a plurality of inwardly directed ribs extending substantially upwardly from the respective third edges of said walls, leaving nonindented first and second wall edges joined to third wall edges by nonindented face ridges located between said ribs for completing an outer truss-like face for each said wall, said inwardly directed ribs defining therebetween a plurality of grooves on the interior of said article including three inner corner grooves communicating at the inner apex of the article, and side grooves, in juxtaposition with said face ridges, communicating with the said corner grooves, said ribs extending substantially up to said corner grooves.
Claim 3
Dependent Claim
50 words
The corner protector according to claim 1 wherein the outer corners of said protector, at the joinder of the first and second triangular edges of said walls, are truncated, separating the third edges from one another and providing communication of said inner corner grooves to the exterior of said protector.
Claim 4
Dependent Claim
16 words
The corner protector according to claim 1 wherein said protector is of substantially uniform thickness throughout.
Claim 5
Dependent Claim
43 words
The corner protector according to claim 1 wherein a wall is indented at regular intervals to provide two side ribs of triangular shape and two central ribs, the latter defining a side groove therebetween aligned with the corner groove between the remaining walls.
Claim 6
Dependent Claim
58 words
The corner portector according to claim 1 wherein said inwardly directed ribs have inner faces in the form of pads for engaging an object being shipped, said inner faces for ribs of a particular wall being in a plane, the corner groove depth being beyond the intersection of the planes of inner faces of said inwardly directed ribs.
Claim 7
Dependent Claim
32 words
The corner protector according to claim 1 wherein said side grooves extend substantially from the lower wall edges to the corner grooves and separate an inner wall surface into individual separated ribs.
Claim 8
Dependent Claim
20 words
The corner protector according to claim 1 wherein each said triangular wall has substantially the outline of an isosceles triangle.
Claim 9
Dependent Claim
17 words
The corner protector according to claim 1 wherein said ribs are substantially normal to said third edges.
Claim 10
Dependent Claim
173 words
A unitary corner protector adapted fOr interposition between the corner of a shipping container and an object being shipped, comprising: three triangular-shaped, molded pulp walls, each of which is joined along first and second edges to matching edges of two remaining walls disposed at right angles to the first and to each other, wherein said walls meet at a common apex at the juncture of said first and second edges of each wall for defining a hollow article of pyramidal exterior form having a triangular base opening between third edges of said walls, said walls being indented forming a plurality of inwardly directed ribs extending substantially upwardly relative to the respective third edges of said walls, the corner protector being inwardly formed to provide inner corner grooves located in juxtaposition with edge junctions of said triangular-shaped walls, the outer corners of said protector at the edge junctions of said walls being truncated, separating the third edges from one another and providing communication of said inner corner grooves to the exterior of said protector.
Claim 11
Dependent Claim
173 words
A unitary corner protector adapted fOr interposition between the corner of a shipping container and an object being shipped, comprising: three triangular-shaped, molded pulp walls, each of which is joined along first and second edges to matching edges of two remaining walls disposed at right angles to the first and to each other, wherein said walls meet at a common apex at the juncture of said first and second edges of each wall for defining a hollow article of pyramidal exterior form having a triangular base opening between third edges of said walls, said walls being indented forming a plurality of inwardly directed ribs extending substantially upwardly relative to the respective third edges of said walls, the corner protector being inwardly formed to provide inner corner grooves located in juxtaposition with edge junctions of said triangular-shaped walls, the outer corners of said protector at the edge junctions of said walls being truncated, separating the third edges from one another and providing communication of said inner corner grooves to the exterior of said protector.
Claim 12
