  • Disposable container for solid animal wastes
    Patent number: 5033780
    Abstract: A disposable container for solid animal waste products comprising a waterproof flexible bag, a locking support structure, a closure strip, and a removable spatula. The support structure has a locking mechanism consisting of a center stay located opposite a pair of hinged support arms that maintain the bag mouth in an open configuration when the bag is in use. The locking support structure provides for accurate placement of solid animal waste into the bag during use, and the convenient collapsibility after use. The disposable container is economical to manufacture, and is also disposable, portable, sanitary, collapsible, and sealable. The disposable container also may be reopened several consecutive times without destroying the integrity of the locking support structure.
