Claim 13:
14. A self-lifting supply container comprising:
a movable tray;
at least one of a guide is fastened to each side of outer perimeter of the movable tray, the guide comprises a body portion that is narrow and a head portion that is connected to and wider than the body portion;
more than one of a container wall, each of the container wall having at least one of a track cut therethrough, each of the container wall is secured proximate to each other forming a container tower, the container tower having a container top, a container bottom, an interior container region, and an exterior container surface, the track is orientated vertically from the container top to proximate the container bottom, the movable tray is sized to fit within the interior container region with the body portion of the guide fitting through the track and the head portion of the guide positioned proximate to the exterior container surface retaining the movable tray within the interior container region and allowing the movable tray to slide up and down the track within the interior container region;
at least one of a pulley is secured on the exterior container surface of each of the container wall proximate to the container top;
more than one of an elastic band, one end of each of the elastic band is attached to the exterior container surface of the container wall proximate to the container bottom, and other end of the elastic band passes over the pulley and is secured to the guide;
a lid, the lid comprises a first interlocking row of ridges integrally formed along one perimeter edge;
a collar is sized to fit perimeter of the container tower and fastens to the container top, the collar having a top collar surface and a bottom collar surface, the lid is sized to cover the collar, the collar comprises a second interlocking row of ridges integrally formed along one perimeter edge, the first interlocking row of ridges and the second interlocking row of ridges movably interconnected such that the lid can be opened by a user to access a supply material within the container interior region, and closed to cover the supply material within the container interior region;
more than one of a panel, the panel comprises a top panel edge, a bottom panel edge, a left panel edge, a right panel edge, an exterior panel surface, and an interior panel surface, at least one of the panel is attached to the exterior container surface of each of the container wall;
a panel contoured lip formed on the bottom panel edge on at least two of the panel that are opposed;
a bottom plate comprises a contoured lip on at least two opposing perimeter edges, the contoured lip engages top surface of the panel contoured lip securing the bottom plate proximate to bottom of the container tower, the bottom plate covers the container bottom; and
more than one of a footer formed into a U-shape, the U-shape creates a panel gap, the footer having a footer mounting hole therethrough, adjacent left panel edge and the right panel edge overlap and slide into the panel gap and a footer fastener passes through the footer mounting hole securing the footer to the panel;
wherein weight of the supply material added to the movable tray causes the movable tray to descend into the container tower, tensioning by stretching the elastic bands and removing portion of the supply material, reducing weight on the movable tray causes the movable tray to partially ascend the container tower, by way of tension in the elastic band, lifting the movable tray and the supply material on the movable tray;
wherein the supply material is accessible to the user proximate to the container top regardless of the amount of the supply material remaining on the movable tray within the self-lifting supply container.
