ABSTRACT:
A corner protector, which is formed entirely from paper honeycomb material, fits between the corner of a container and the corner of a relatively rigid object in the container and thereby positions the object within the container and protects it from impacts to which the container may be subjected. The corner protector, when in its assembled configuration, has at least three panels which are arranged perpendicular to each other. Being formed from paper honeycomb material, each panel has inner and outer facer sheets and honeycomb cells interposed between the facer sheets, with the axes of the cells being perpedicular to the facer sheets. The three panels share a common outer facer sheet, with the first and third panels being joined to the second panel along fold lines in that facer sheet. However, the inner facer sheets of the three panels are clearly distinguishable by reason of slit lines that separate them. Moreover, in the region of the slit lines the honeycomb cells are crushed such that the inner facer sheets are beveled downwardly to the fold lines. The panels abut along the beveled surfaces of their inner facer sheets. An edge protector has at least two panels which are joined through a common outer facer sheet and are beveled at their inner facer sheets opposite a fold line in the common outer facer sheet. This permits the protector to be folded over an edge of the object with the inner facer sheets presented inwardly toward the object.
