<p>A foldable box convertible from a relatively flat storage configuration to a deployed configuration ready to receive contents. The bottom panels of the stored box deploy or move to form a box bottom as the sides panels of the box are moved to be a right angles to each other. The side panels of the box may be formed of a double thickness of material, and form a recess to engage and secure an inner bottom panel. The bottom panels are shaped and positioned to allow the panels to easily slide by each other as the box is converted from the storage configuration to the ready to receive contents configuration.</p>
