Abstract
A peripherally continuous frame is provided for receiving the open mouth of a bag therethrough with the free edge portions of the bag mouth folded outwardly and back over the outer surfaces of the frame. Peripherally spaced portions of the frame each have one end portion of an elongated arm member pivotally anchored thereto for oscillation about an axis transverse to the arm member and the corresponding frame portion and generally paralleling the medial plane of the frame. The free end portion of each arm member includes an elongated longitudinally extending clamp portion thereof which is generally U-shaped in transverse cross section, opens laterally outwardly of the arm member and includes open opposite ends. The clamp portions are swingable into and out of positions with an adjacent frame portion embracingly received therein and extending longitudinally therealong, whereby when the free edge portion of a bag is folded outwardly and back over the adjacent frame portions they may be releasably clamped to the frame portions by the U-shaped free end portions of the arm members. The frame includes an elongated outwardly projecting handle supported from one marginal portion thereof.
