Method of making a pack for packaging fragile articles

Abstract

A pack or container for the storage and transportation of fragile articles such as eggs, light bulbs and the like comprises a laminate consisting of a corrugated band or strip and a covering band secured together to give spaced troughs extending transversely of the material, there being spaced, parallel slits in the material extending in the longitudinal direction thereof, the slits extending wholly through the covering band to define separate side-by-side strips thereof and only partially through the corrugated band to define side-by-side strips of such band joined together at the peaks of the corrugations. The junctures form fold lines extending longitudinally of the packing material about which, upon erection of the pack, transversely adjacent regions provide mutually inclined walls defining pockets to receive the articles. The strip-like covering band is connected to the corrugated band and then several parallel longitudinal slits, spaced apart from another are made in the covering band and in the corrugating band to such depth that these slits completely sever the covering band but terminate below the tops of the corrugations so that several supporting webs running parallel and connecting with one another result. After insertion of the articles to be packed in the troughs of the corrugations, the supporting webs are bent along the fold lines with the corrugation peaks running in the longitudinal direction of the band parallel to one another, and are thereby placed around the articles to be packed.
