Abstract: A modular container wall unit and containment system formed therewith, each wall unit being comprised of a central panel having wing-like panels integrally formed on opposite sides thereof and angularly intersecting the central panel at an angle such that, when the wings of another modular unit are affixed to the central panel of the present unit, and one or more like units are affixed to the second and third units, a chamber is formed which, when combined with a bottom panel and a top panel, defines a container. The central panel of each unit is designed to include recessed areas adapted to mate with the wing panel of another modular unit to facilitate the expansion of the system to form an adjacent cell or chamber. Furthermore, the modular unit is configured to withstand lateral loads and maintain system integrity.

Abstract: A holder is provided for both supporting and carrying napkins and containers, such as condiment bottles. The holder includes a lower tray for napkins and an upper tray supported thereabove on struts for containers. The struts are constructed with vertically extending slots in which a retaining bar is received to rest upon the napkins and hold them securely in place. A handle extends above the upper tray to provide means for readily transporting the tray, while at the same time providing structure to engage and help support the containers. Flanges are provided around the perimeter of the upper and lower trays to assist in holding the containers and napkins in place.
