  • Patent number: 4282911
    Abstract: A combined hanger and bag. The hanger is substantially triangular and comprises congruent parallel frame members with snap extensions on one member and corresponding openings on the other member so that the two members may be snapped together. A hook is provided for suspending the hanger by one of the frame members. A bag having a corresponding triangular opening is provided with reinforcements having bag openings which may be engaged by the extensions of the frame member which carries the snap extensions. The reinforcing members are also provided with longitudinal beads which are received in recesses located inwardly of the extension. The lower run of the hanger receives a reinforcement that extends directly upwardly from the bag. The other two reinforcements are folded over the outside of the frame which carries the snap extensions so that the openings engage the snap extensions and the longitudinal reinforcement bead engages the recess inwardly of the snap extensions.
