  • Patent number: 5014943
    Abstract: A hoop, in collapsed configuration fitting readily into the mouth of a plastic trash bag, is formed from a synthetic resionous material and is peripherally expandable from its collapsed form to fit tightly against the inner surface of the bag and hold the bag securely in place with the mouth open. The hoop has provision for either free-standing use with the bag mouth in the vertical position, when trash may be swept directly into the opening, or mounting on a vertical support with the bag mouth in the horizontal position for use as a trash receptacle. A pan attached by a flexible integral connection to the hoop serves both as a threshold when sweeping trash into the bag, and as a lid when the bag is used as a trash receptacle. The flexible integral interconnection of the hoop and pan also permits compact storage and transportation of the holder in assembled form, and even greater space savings when stored or shipped in "blank" form as one flat integral unit.
