Abstract: A metallic container includes a body with a bottom and a neck. The neck includes a thread profile, a curl, and a curl transition between the thread profile and the curl. The curl defines an opening. The thread profile of the neck is configured to receive a corresponding thread profile of a reusable closure when the reusable closure is coupled to the neck. The curl is configured to engage with an insert positioned proximate to the curl and within a cavity defined in a casing of the reusable closure. The curl is configured to reduce damage to the insert during at least one of the reusable closure being coupled to or uncoupled from the neck. Methods for fabricating the curl include applying a thread profile to a metallic container neck, reducing a diameter of a portion of the neck above the thread profile, and curling the reduced-diameter neck portion.

Abstract: An aerosol can fabrication process comprises the following steps: formation of slugs from an aluminium-based alloy having the following composition, in weight percentage: Si 0.35-0.45 Mg 0.25-0.40 Mn 0.05-0.15 Fe 0.12-0.20 Total of minor elements ?0.15% Al Balance. thermal treatment of the slugs, forced cooling of the slugs, cold impact extrusion of a slug so as to form a can, applying a lacquer inside the can.
