Abstract
Abstract The invention provides a support structure for suspending an open bag from a wall and the like, such as the door of a kitchen cupboard, the support structure having a hoop including a flat rear portion of a selected vertical height. The bag is received inside the hoop with the portion adjacent its mouth folded over the top of the hoop. At least one attachment plate is provided for mounting on the wall. The plate has a downwardly projecting lip, and below the lip a ledge spaced from the bottom edge of the lip by less than the selected vertical extent of the hoop, so that the hoop will be retained by engagement of the rear portion behind the lip, while resting on the ledge. The hoop is thus suspended from the wall extending horizontally and with the mouth open to receive items dropped into the bag, the folded-over portion of the bag being trapped between the hoop and the attachment plate to retain the bag in a manner which increases with the weight in the bag. The hoop is notched or a plurality of clips are provided to hold securely a bag that is otherwise too small for the hoop. A lid is usually provided to close the mouth of the bag.
