Dome Formation Profile & Method of Lightweight Container Design and Manufacture

A lightweight metal dome profile having a reduced pull down comprising:

• a lightweight dome profile positioned at a terminal end of a metal container that is configured to be capable of a controlled sequential dome profile deformation;
• wherein said lightweight dome profile further comprises:
• at least one initial deformation panel positioned at an approximately central position on an inner dome profile of said lightweight dome profile;
• at least one buttressing structure coupled with said initial deformation panel;
• a circumferentially positioned inner leg configured to have an inner conical leg angle coupled with said at least one buttressing structure and a plurality of geometric panels;
• and
• wherein the pulldown required to generate said lightweight dome profile configured to be capable of a controlled sequential dome profile deformation is 20-75% less than a comparable dome profile that is not configured to initiate said controlled sequential dome profile deformation.

A deformation resistant metal dome profile comprising:

• a lightweight dome profile positioned at a terminal end of a metal container that is configured to be capable of a controlled sequential dome profile deformation;
• wherein said lightweight dome profile further comprises:
• at least one initial deformation panel positioned at an approximately central position on an inner dome profile of said lightweight dome profile;
• at least one buttressing structure coupled with said initial deformation panel;
• a circumferentially positioned inner leg configured to have an inner conical leg angle coupled with said at least one buttressing structure and a plurality of geometric panels;
• and
• wherein said controlled sequential dome profile deformation is initiated in response to the application of a deformation energy to said lightweight dome profile such that movement of said initial deformation panel transfers said deformation energy outwardly onto said at least one buttressing structures generating a staged leveraged deformation displacement action that delays deformation of said inner conical leg angle.
