ABSTRACT:
A one-piece container formed as an injection molding preferably from polypropylene. The single piece is molded in preformed sections joined by thinner portions or parts of material which serve as hinges, the sections being relatively moveable about these parts. The sections are preformed to constitute portions of a container along with a closure for the container so that when the sections are moved about joint parts a complete container with a closure cover is formed. Preferably the container has inwardly extending flexible members formed on at least one section to engage an article within the container to retain it in position. The container is particularly adapted for use with calculators.
