Abstract
The present invention relates generally to forming a threaded neck in a metal bottle manufactured by a process known as impact extrusion. More specifically, the present invention relates to methods, apparatus and alloy compositions used in the impact extrusion manufacturing of containers and other articles with sufficient strength characteristics to allow threading the container necks to receive a threaded closure on the threaded neck.
Claims21
A metallic bottle with a threaded neck formed by an impact extrusion process, comprising:
- a bottom dome portion;
- a body portion extending upwardly from said bottom dome portion;
- a neck portion extending upwardly from said body portion;
- threads formed on an exterior surface of said neck portion;
- and
- an opening positioned on an uppermost portion of said neck portion,
- wherein said metallic bottle is comprised of a recycled aluminum alloy with the following composition:
- between about 97.70 wt. % aluminum and about 98.50 wt. % aluminum,
- between about 0.16 wt. % Si and about 0.24 wt. % Si,
- between about 0.37 wt. % Fe and about 0.48 wt. % Fe,
- between about 0.08 wt. % Cu and about 0.15 wt. % Cu,
- between about 0.48 wt. % Mn and about 0.71 wt. % Mn,
- between about 0.34 wt. % Mg and about 0.52 wt. % Mg,
- between about 0.06 wt. % Zn and about 0.12 wt. % Zn,
- between about 0.01 wt. % Cr and about 0.04 wt. % Cr, and
- between about 0.00 wt. % Ti and about 0.04 wt. % Ti;
- and
- wherein said threaded neck has a predetermined geometry adapted to receive a closure.
A threaded metallic bottle formed from a recycled aluminum alloy in an impact extrusion process, comprising:
- a bottom portion;
- a body portion extending upwardly from the bottom portion;
- a neck portion with a decreased diameter extending upwardly from the body portion;
- threads formed on an exterior surface of the neck portion;
- and
- an opening positioned on an uppermost portion of the neck portion, wherein the recycled aluminum alloy is blended from a scrap aluminum alloy mixed with a 1070 aluminum alloy, the scrap aluminum alloy comprising:
- between about 0.20 wt. % Si and about 0.32 wt. % Si;
- between about 0.47 wt. % Fe and about 0.59 wt. % Fe;
- between about 0.10 wt. % Cu and about 0.22 wt. % Cu;
- between about 0.78 wt. % Mn and about 0.90 wt. % Mn;
- between about 0.54 wt. % Mg and about 0.66 wt. % Mg;
- between about 0.06 wt. % Zn and about 0.18 wt. % Zn;
- between about 0.00 wt. % Cr and about 0.08 wt. % Cr;
- and
- between about 0.00 wt. % Ti and about 0.08 wt. % Ti.
A metallic bottle for a beverage formed in an impact extrusion process, comprising:
- a body portion;
- and
- a neck portion with threads configured to receive a threaded closure which can be selectively opened and closed after the metallic bottle is filled with the beverage, wherein the metallic bottle is formed of a recycled aluminum alloy that comprises:
- between about 0.16 wt. % Si and about 0.24 wt. % Si,
- between about 0.37 wt. % Fe and about 0.48 wt. % Fe,
- between about 0.08 wt. % Cu and about 0.15 wt. % Cu,
- between about 0.48 wt. % Mn and about 0.71 wt. % Mn,
- between about 0.34 wt. % Mg and about 0.52 wt. % Mg,
- between about 0.06 wt. % Zn and about 0.12 wt. % Zn,
- between about 0.01 wt. % Cr and about 0.04 wt. % Cr, and
- between about 0.00 wt. % Ti and about 0.04 wt. % Ti.
