Abstract
Abstract The present invention relates generally to edge protectors. More particularly, the present invention relates to a temporary protector for an edge of an article and a method of making edge protectors. In a preferred embodiment, the edge protector according to the present invention includes a first part having a scoring line. The scoring line extends from first to second edges of the first part and from a first side surface of the part substantially to a second side surface. A pliable film is applied to the second side surface of the first part for permitting flexing of the first part along the scoring line. A second part includes a recess in a first side surface sized to substantially encase a portion of the first part extending generally perpendicularly from the scoring line. The portion of the first part is secured within the recess in the second part. When it is desired to use the edge protector according to the present invention, the second part is preferably arranged upon a surface of the article to be protected with the portion of the first part not encased within the recess of the second part extending outwardly over the edge of the article to be protected. The extending portion of the first part is bent downwardly about the scoring line with the thin film acting as a hinge such that the extending portion lies substantially flush against a second surface of the article to protect the same.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
112 words
A protector for an edge of an article comprising: a first part having a scoring line, said scoring line extending from a first edge to a second edge of the first part and from a first side surface of the part closely adjacent to a second side surface; pliable film means on the second side surface of said first part for permitting flexing of said first part along said scoring line; a second part having a recess in a first side surface which encases a portion of the first part extending from the scoring line; and means for securing the portion of the first part within the recess in the second part.
Claim 2
Dependent Claim
112 words
A protector for an edge of an article comprising: a first part having a scoring line, said scoring line extending from a first edge to a second edge of the first part and from a first side surface of the part closely adjacent to a second side surface; pliable film means on the second side surface of said first part for permitting flexing of said first part along said scoring line; a second part having a recess in a first side surface which encases a portion of the first part extending from the scoring line; and means for securing the portion of the first part within the recess in the second part.
Claim 3
Dependent Claim
37 words
The protector of claim 1, wherein an exposed surface of the pliable film is substantially coplanar with the first side surface of the second part when the portion of the first part is secured within the recess.
Claim 4
Dependent Claim
31 words
The protector of claim 1, wherein the pliable film means is secured to the first part by an adhesive which does not interfere with the pliable nature of the film means.
Claim 5
Dependent Claim
19 words
The protector of claim 3, wherein the pliable film means is polyethylene and the adhesive is ethyl vinyl acetate.
Claim 6
Dependent Claim
32 words
The protector of claim 1, wherein the width of the recess is less than one half of the total length of the second part in a direction parallel with the scoring line.
Claim 7
Dependent Claim
24 words
The protector of claim 1, wherein the height of the recess is less than one half of the total height of the second part.
Claim 8
Dependent Claim
18 words
The protector of claim 1, wherein the second part is of substantially denser material than the first part.
Claim 9
Dependent Claim
23 words
The protector of claim 1 or 7, wherein the first part is low density polystyrene and the second part is high density polystyrene.
Claim 10
Dependent Claim
18 words
The protector of claim 1, wherein the first part is secured to the second part by an adhesive.
Claim 11
Dependent Claim
18 words
The protector of claim 1, wherein the first part is press-fit into the recess in the second part.
Claim 12
Dependent Claim
21 words

Claim 13
Dependent Claim
185 words
An edge protector comprising: a carrier body including a scoring line extending from first to second edges of the body and from a first side surface through the body to substantially a second side surface of the body; a film layer having dimensions sufficient to cover at least an area surrounding the scoring line and being sufficiently pliable to bend at least 90° without breaking; adhesive means for securing the film layer to the area of the second side surface of the body surrounding the scoring line, said adhesive means being sufficiently pliable to permit at least 90° bending of the body about the scoring line with the film layer acting as a hinge; and a support body having a recess in a first side surface sized to receive a portion of the carrier body extending from one side of the scoring line, and means for securing said carrier body portion in said recess such that the first side surface of the support body is generally coplanar with an exposed side surface of the film layer secured to the second side of the carrier body.
Claim 14
Dependent Claim
185 words
An edge protector comprising: a carrier body including a scoring line extending from first to second edges of the body and from a first side surface through the body to substantially a second side surface of the body; a film layer having dimensions sufficient to cover at least an area surrounding the scoring line and being sufficiently pliable to bend at least 90° without breaking; adhesive means for securing the film layer to the area of the second side surface of the body surrounding the scoring line, said adhesive means being sufficiently pliable to permit at least 90° bending of the body about the scoring line with the film layer acting as a hinge; and a support body having a recess in a first side surface sized to receive a portion of the carrier body extending from one side of the scoring line, and means for securing said carrier body portion in said recess such that the first side surface of the support body is generally coplanar with an exposed side surface of the film layer secured to the second side of the carrier body.
Claim 15
Dependent Claim
131 words
A protector for an edge of an article comprising: a first part having a scoring line, said scoring line effectively separating said first part into first and second portions, said scoring line extending from a first edge to a second edge of the first part and from a first side surface of the part closely adjacent to a second side surface, such that said first portion may be moved to a position substantially perpendicular to the second portion without complete separation of the first and second portions; a second part having a recess in a first side surface, said recess receiving at least a portion of the second portion of the first part; and means for securing the second portion of the first part within the recess in the second part.
Claim 16
Dependent Claim
131 words
A protector for an edge of an article comprising: a first part having a scoring line, said scoring line effectively separating said first part into first and second portions, said scoring line extending from a first edge to a second edge of the first part and from a first side surface of the part closely adjacent to a second side surface, such that said first portion may be moved to a position substantially perpendicular to the second portion without complete separation of the first and second portions; a second part having a recess in a first side surface, said recess receiving at least a portion of the second portion of the first part; and means for securing the second portion of the first part within the recess in the second part.
