Abstract
Official abstract text for this publication.
A shaped metal container comprising less metal than prior art shaped metal containers while still able to handle sufficient axial load and undergo shaping processes, including necking, without wrinkling, buckling, collapsing or other physical defect is disclosed. Processes for shaping a metal container having a sidewall of variable thickness, wherein a portion of the sidewall having a variable thickness is shaped using a die or dies are also disclosed.
First claim
Opening claim text (preview).
The invention claimed is: 1. A shaped aluminum container, comprising: a sidewall including an upper sidewall having a thickness in a range of about 0.005 inch to about 0.0085 inch, wherein the sidewall includes a top necked portion and a bottom necked portion, wherein a thickness of the sidewall in the bottom necked portion varies from the thickness of the upper sidewall by at least 0.001 inch to not greater than 0.004 inch; and wherein an entire exterior surface of the sidewall is smooth. 2. The container of claim 1 , wherein the container is made from an aluminum alloy having a hard temper.
