Abstract: Aerosol cans, more particularly, aluminum aerosol cans made from disks of aluminum coil feedstock, are provided. A method for necking aerosol cans of a series 3000 aluminum alloy is also provided. The method prevents the cans from sticking in the necking dies and produces a can with a uniquely shaped profile. The aluminum aerosol cans that are produced have the attributes of strength and quality, while being produced at a cost that is competitive with steel aerosol cans.

Abstract: An aluminum container is comprised of a base portion, a substantially vertical wall portion extending upwardly from the base portion, a transition portion extending from the wall portion, and a neck portion extending from the transition portion. The neck portion is tapered and has an upper end having a wall thickness that is preferably less than the thickness of the wall of the remainder of the neck portion. The upper end of the neck portion may also be chamfered. The aluminum container of the present invention may be combined with a threaded sleeve to form a receptacle. The sleeve has an outer surface and an inner surface. The outer surface has threads thereon and the inner surface has a taper complementary to the taper of the neck portion so as to form a friction fit with the neck portion. The sleeve may also have a notch formed in the periphery of its upper outside surface.

Abstract: A method of affixing a sleeve to the neck of an aluminum container of the type having a tapered neck and wherein said sleeve has a complementary taper. The method comprises positioning said sleeve onto said neck wherein a portion of the neck extends beyond said sleeve and wherein said positioning causes said complementary taper of the sleeve and said taper of the neck to form a friction fit, said friction fit preventing rotation of said sleeve relative to said neck, wherein said friction fit is formed without expansion or deformation of said neck, and curling the portion of the neck extending beyond the sleeve so that the curl covers at least a portion of the upper end of said sleeve. Because of the rules governing abstracts, this abstract should not be used to construe the claims.
