In a pack for eggs or other fragile articles constructed of corrugated strips glued to and braced by external flat strips, in which the corrugated strips are joined together at their inner apices and folded at these junctions after the manner of U.S. Pat. Nos. 3,955,744 and 3,983,680, the closure of the pack is made along one of the narrower sides instead of along one of the wider sides, and at least one of the abutting narrow flat strips is provided with tongues of a length greater than the width of the strip that are stamped out of the material of one of the wider flat strips. These tongues are bent over so as to overlap the adjoining flat strip, where they can be glued to the flat strip to hold the pack together. The fastening is thus provided out of the material of the pack without waste, and no fasteners or adhesive strips need be applied from an external source in the packing operation. |
