The mark consists of The mark consists of a three-dimensional configuration of a container having, on each side of its front surface, six elongated recessed grooves arranged in a generally radiating pattern and extending inward from the side edges toward the center of the front surface. The grooves vary in length and angle and are arranged in generally symmetrical groupings on opposite sides of the container. The mark further consists of the stepped side contours of the container adjacent to the grooves, which define changes in the container's side profile in the areas where the grooves extend inward from the side edges. The broken lines depicting the neck, top, shoulders, upper side edges, and base of the container indicate placement of the mark and are not claimed as features of the mark.
