Collapsible box

Abstract

A collapsible box is manufactured simply and inexpensively, and can support hanging files in a secure manner. The box components are all constructed of plastic, and pivotal connections between all of the components (to provide for the collapsing and erecting action) are provided solely by plastic pivot pins integral with the plastic components, and pivot pin receiving openings formed in the plastic components. The pivotal elements snap together and are disassemblable, so that the container may be easily assembled together and may be taken apart without the necessity of removing accessory elements that have been specifically inserted to pivotally connect the components together. Metal bars for supporting hanging files are themselves supported by channel defining elements extending inwardly from end panels of the box. The channel defining elements have closed sides and a closed bottom, and a closed end defined by the end panel. The metal file supporting bars may be moved in place supported by the channel elements by moving them downwardly through openings in the tops of the elements defined by beveled surfaces, or inserted through the open ends of the channels. The length of the bars is essentially the same as the spacing between the end panels when they are vertical and support the container in its operative (erected) position.
