One piece container particularly adapted for calculators

Claim 1

An article which is a container which is formed from substantially a single piece of material which includes a piece of material formed in sections, the sections being joined by hinge parts of the material which is sufficiently thin to allow hinging movement of the material, whereby sections adjacent to a hinge part can be moved relatively with respect to the hinge part, certain of said sections being preformed to constitute portions of a container and to form a container when the sections are moved relatively with respect to a joining hinge part, and a further section being preformed to constitute a closure and moveable relative to a hinge part to provide a closure for a container formed by other sections, there being three sections, which lie in a plane before movement about the hinge parts, said sections including a back section having at least partial side walls and at least a partial bottom wall portion, a front section having at least partial side walls and at least a partial bottom wall portion, said front and back sections being constructed to be moved relatively about a hinge part so that the said partial side walls and partial bottom walls on the front and back sections come into juxtaposed abutting relationship, and a third section forming a cover section attached to the back section by a hinge part, the cover section having a front portion and at least partial side walls constructed to come into juxtaposed abutting relation with partial side walls on the back section with the cover section forming a closure for a portion of the front of the container.
