Abstract

An edge protector including a main body for installation on a box or package for protection and reinforcement. The edge protector includes first and second legs and a cover layer that extends over the outer surface of both of the first and second legs. An attachment portion of the cover layer extends over the outer edge of each leg and is retained along an inner surface of the leg on a release liner. During use, the attachment portions are both released from the release liner on the inner surface of the first and second legs such that an adhesive on the attachment portion can be used to attach the edge protector to a package or product.

Claims (17)

1. An edge protector for using in protecting a product, comprising:

a main body including a first leg and a second leg, each of the first and second legs including an outer edge;

a release liner positioned along a portion of an inner surface of the main body in close proximity to the outer edge of both of the first and second legs; and

a cover layer positioned on an outer surface of the main body, the cover layer having an adhesive on an inner surface of the cover layer;

wherein the cover layer includes first and second attachment portions that each extend around one of the outer edges of the first and second legs and are each received on one of the release liners positioned on the first and second legs.

2. The edge protector of claim 1 wherein each of the release liners includes a release tab.

3. The edge protector of claim 2 wherein a score line defines the release tab in the release liner such that the release tab of the release liner separates from the release liner along the score line and remains attached to the first or second attachment portion upon removal of the first or second attachment portion from the release liner.

4. The edge protector of claim 1 wherein the release liner includes a second adhesive on an inner surface of the release liner and the release tab is devoid of the second adhesive.

5. The edge protector of claim 1 wherein each of the first and second attachment portions are movable from a storage position in contact with the release liners and an attachment position in which the attachment portions extend parallel to the first and second legs.

6. The edge protector of claim 1 wherein the main body is formed from paperboard.

7. The edge protector of claim 1 wherein the main body has a V-shape and the first and second legs are joined at an apex.

8. The edge protector of claim 1 wherein the cover layer is formed from paper.

9. An edge protector for using in protecting a product, comprising:

a main body including a first leg and a second leg, each of the first and second legs including an outer edge;

a release liner positioned along a portion of an outer surface of the main body in close proximity to the outer edge of both of the first and second legs; and

a cover layer positioned on an inner surface of the main body, the cover layer having an adhesive on an inner surface of the cover layer, wherein the cover layer includes first and second attachment portions that extend around the outer edges of the first and second legs and are received on the release liner on each of the first and second legs.
