ABSTRACT:
An improved corner guard that consists of a guard body with an adhesive bottom surface layer, a pair of orthogonal fold lines designed to align with a pair of corner edges, a pair of fold-over tabs extending outwardly from the fold lines, the tabs designed to fold over the corner edges and adhere to a back surface of the corner. A folding enhancement means, such as a perforated or pre-scored line is positioned along the length of the tabs on the fold lines so that the tabs can be quickly and properly folded. A pair of fixed edge tab portions extend inwardly from the fold lines, and preferably include at least one curvilinear portion, and a central portion extends inwardly from the fixed edge tab portions. The central portion extends away from the corner, and may additionally include one or more curvilinear portions to prevent objects from catching or tearing on the corner guard. Additionally, the entire perimeter of the corner guard has a beveled edge to further allow objects to slide easily over the guard without catching or tearing. The fold-over tabs may be torn off after alignment of the guard with the corner of the book. The fold-over tabs may be positioned permanently at right angles to the body for alignment of the guard with the book, and may include means for biasing the book cover in a flat and closed position.
