  • Patent number: 6102278
    Abstract: A foldable pan for receiving dirt and debris is initially formed as a relatively flat sheet member and thereafter folded into shape has a first body member and a second body member which are joined by a first side member that is foldably attached to each body member. A second side member foldably attaches to the first body member, while a third side member foldably attaches to the second body member. A first flap is connected to the first body member by a connection member that is foldably attached to each. A second flap and a third flap are each foldably attached to the connection means. The second body member is folded such that it is essentially parallel to the first body member with the first side member acting as a side wall of the pan. The second side member and the third side member are each folded up such that the second side member overlaps the third side member--these two side members acting as a second side wall of the pan.
