Abstract
Abstract Multi-sided containers having side walls and a bottom wall, formed from a stamped or di-cut integral blank and characterized by having, in certain embodiments of the invention, horizontally projecting feet extending from the bottom wall that serve as stabilizers for the structures. The feet may be defined in part by a lock-slot providing a tab that can be folded upwardly to retain the structure in expanded, although collapsible condition. Alternatively, the lock-slot can be omitted and the feet folded from a horizontal into an upright position and secured to the confronting side wall to provide a permanently erected or expanded structure. In all embodiments of the invention, the blanks are designed so that the bottom wall is collapsible inwardly and upwardly and may be formed by a single bottom section, or by two similar cooperating bottom sections.
