  • Patent number: 4102485
    Abstract: A multipart, collapsible box for transporting small items being made of a folded sheet casing and two end elements. The casing is folded to form a bottom, side walls and inwardly extending flanges. The end elements are adapted to have the end edges of the casing to be fitted and secured therein. Each end element has two side portions, each with a projection to be fitted into a hole in the respective side wall of the casing for securing the end element to the casing. Guide bars are provided on the end elements for stiffening the same and for guiding the bottom of the casing into a track formed by the bottom of the guide bars and a bottom flange on the end element. Further guide bars are formed in the upper corners of the end elements for guiding and holding the side walls and the flanges of the casing into place. A central wall portion of the end elements is formed sloping inwardly between the bottom flange and the top flange to form a handle on each end element.
