Claim 0:
1. 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; and
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;
wherein weight of a 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 a 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.
