Abstract: An improved structure art knife blade container comprised of an inner case that slides lengthwise into an outer case. An elastic component is positioned lengthwise between the interior section of the outer case and the side of the inner case, thereby providing a spring force to push the inner case outward in a straight line, and a recess capable of holding a plurality of art design knife blades in a stacked arrangement is formed in the inner case. As such, during the sliding operation of the inner and outer case, a horizontal ejection rib contacts the uppermost art design knife blade in the inner case and ejects it horizontally from a dispensing slot, thereby achieving the convenient dispensing of art design knife blades.
