Abstract
A tote and storage container of the variety used for filing and archive purposes comprising a rectangular body folded from corrugated plastic, a combined handgrip and stacking frame member, and a lid unit which may be selectively removed from or hingedly mounted to the container. The combined handgrip and stacking frame reinforces the handgrip openings in the container body and the top corners of the container walls, provides a stacking shoulder allowing containers without lids to be stacked, and has a retaining rim to keep a vertical column of like containers stacked without the containers sliding off the top or becoming misaligned. The lid unit may be securely attached to the container to support heavy loads when the container is inverted, may be pivoted open or closed along a hinge line, or may be completely removed.
