Abstract: A reusable bag incorporating a foldable support structure, used for containment of item(s) for carrying by a person, comprising a bag made of a flexible, durable material removably attached to a pair of essentially U-shape, semi-rigid support members, that extend under opposite ends of the bag and up opposite sides at an angle which causes them to intersect just above the mouth of the bag where they are swingably attached to a rigid handle which straddles the mouth of the bag. Attached to the inside of the bag is a rigid bottom panel which lies horizontal on the bottom of the bag when in use and drops to a vertical position when the bag is inverted for folding. Two closure straps with snaps, located on one end near the top edge of the bag whose corresponding snap components are located on the opposite end, are used to maintain the bag in a folded condition. By virtue of this configuration, this bag is free-standing and stable whether empty or full, and may be folded flat when not in use.

Abstract: A color indicating apparatus which comprises a plurality of concentric overlappingly arranged discs which are rotatably mounted on a pivot post which is carried by a base. Each disc is basically transparent and includes a plurality of windows with each window being colored to a certain percentage of screening. Each disc is a certain primary color with there normally being utilized four in number of discs with there being four primary colors. Mounted on the base is a locking device which is to be movable to engage with the peripheral edge of the overlapped discs so as to lock the discs when located in a selected position. The visually observable color of each window within the outer disc will assume various shades as determined by the color density of the overlapped windows.
