  • Patent number: 3934894
    Abstract: An enclosed cart for storing and transporting refuse or other bulky materials has an enclosing lid which overlies the opening to the container, preventing the undesirable entrance of rain or extraneous debris. The cart has a small central hole in the floor panel which allows water to drain from the interior. The cart has wheels at one edge and a handle at the other whereby it may be lifted and moved easily from place to place. The interior of the cart is adapted to enclose cans or bags. Special bag holders fit into the interior of the cart and cooperate with the upper edge of the cart to hold bags. The bag holders may be single or plural whereby one or more bags may be held. The bag holders hold the tops of the bags open and prevent the tops of the bags from being drawn into the interior of the cart under the weight of added material. The bag holders are formed of sheet metal stampings or fabricated from bent wire.
