ABSTRACT:
A disposal chute for waste paper, cardboard, and other packing materials is disclosed which is intended to temporarily connect a container to a building. The disposal chute is permanently positioned adjacent to the building. A slip joint construction connects the chute to the building in such a manner as to completely enclose the mating surfaces while allowing relative movement between the chute and the building. The mating surface at the building is designed so that the relative movement does not adversely affect the brick and mortar construction of the building surrounding the opening for the chute. A container, which may be removed and replaced relatively often, is positioned adjacent to the chute to be in communication with the building. The placing and removing of the container results in the relative movement between the chute and the building.
