Abstract
Corrugated box constructions suitable for packaging, storing and transporting flat rectangular objects such as books and the like. The box has an upper member and a lower member, each with a generally rectangular central panel, a pair of side panels, one of which is hingedly joined to each of the opposite ends of the central panel. Attached to each side panel of the upper member is an underlying panel and attached each side panel of the lower member is an overhanging panel. The side panels of the lower member fold upward, then the overhanging panel folds parallel to the central panel. The side panels of the upper member fold perpendicularly downward, then underlying panel folds under the central panel of the lower member. The upper member is attached to the lower member with an optional adhesive or strap. Preferably an adhesive is situated on the overhanging and underlying panels. The construction allows for packaging products of various sizes and hence greatly reduces waste.
