Abstract: Lightweight metal containers are formed from high-strength metal alloys by impact extrusion of a cup-shaped container having a substantially larger diameter than the finished container, drawing and wall ironing the extruded container to reduce its diameter and wall thickness while increasing the height of the container to the appropriate diameter, wall thickness and height.

Abstract: A dispensing closure is provided for attachment to the discharge port of a standard circular-headed tube. The closure comprises a skirt with a circular cross-sectional shape at its base that merges gradually to an oval-shaped face at its top. When the closure is attached to a standard circular-headed tube, with the long axis of the oval face oriented substantially parallel to the straight crimped edge of the filled tube, the combination of closure and tube appears to the ordinary observer to have a continuously oval cross-sectional shape throughout the length of the combination. The dispensing closure can be manufactured using typical injection-molding techniques, and may be adapted for use with dispensing mechanisms and attachment means known in the personal care products industry.
