Abstract: A corrugated, lightweight, foldably collapsible container for storing infectious waste in first and second storage positions is disclosed. The container comprises a collapsible receptacle having a foldably sealed bottom portion and a plurality of side panels forming an upwardly opening receptacle for receiving and containing waste therein. The container further has a top portion integrally formed with the receptacle, the top portion being operable to foldably form a spout portion for receiving waste therethrough, and also operable to quickly and foldably close into a first storage position for temporary storage of its contents, and to foldably close into a second storage position to facilitate more permanent storage of the waste contained therein, and further to facilitate safe movement of the container. In a preferred embodiment the container also incorporates a leak-proof removable plastic bag acting as a liner to further provide additional protection against leaks of the contents of the container.
