20090014445 | Collapsible plastic container - Disclosed is a collapsible, portable container having a roof, a base, two foldable end walls and two removable side walls. The end walls and side walls of the container are load bearing elements having a twinned wall structure made of rotomolded plastic. The container is collapsed by removing the side walls and inwardly folding the end walls to draw the roof closer to the base. The load bearing capacity of the end walls and the side walls can be increased by arched indentations formed within the twinned wall structure. | 01-15-2009 |
20110084069 | Collapsible container with a sliding lock feature - A collapsible, portable container having a roof, a base, two foldable end walls and two removable side walls. The container is collapsed by removing the side walls and inwardly folding the end walls to draw the roof closer to the base. A slide lock feature is present which alternatively allows or prevents the inward folding of the container end walls. | 04-14-2011 |
20110180533 | Collapsible refuse bin - A collapsible refuse bin which has two ends walls and two side walls atop a base. The end walls, side walls and base are twinned wall plastic components. The side walls are made of two panels which are pivotally attached to one another along vertical axis. The end walls are pivotally attached to the base. The side walls engage a base along a tongue and groove means. Side walls and end walls have mutually engaging edges. Removal of the side walls followed by folding down the end walls converts the refuse bin to a collapsed position. | 07-28-2011 |
20120055834 | Plastic dumpster - A unitary plastic container, which is optionally used for waste collection comprises a base, a front wall, a back wall and two opposing side walls, each wall extending upwardly from the base to define an open container top and an interior container volume. Each side wall has an outwardly extending sidewall portion which is outwardly offset relative to the rest of the container side wall. In each outwardly extending sidewall portion, an elongated cutout, indentation or channel is present. The elongated channel has a forward opening, a rearward opening and an elongated side opening extending from the forward opening to the rearward opening. The elongated channel lies within the interior container volume and divides the outwardly extending sidewall portion into two areas: an upper outwardly extending sidewall portion and a lower outwardly extending portion. The outwardly open elongate channel may be fitted with a reinforcing sleeve. | 03-08-2012 |
