IMPROVED METAL CAN AND METHOD OF MAKING

摘要

PURPOSE: An improved metal can and method of making are provided to reduce of can remarkably, and to tolerate additional intension and transformation. CONSTITUTION: A method of making a noncylindrical shaped metal can that is provided with a stylized, irregular shape includes steps of forming a substantially cylindrical side wall portion (12) that has a plurality of ribs integrated therein. These ribs provide additional strength to the side wall portion. The cylindrical side wall portion then is shaped into a noncylindrical, stylized shape. The ribs (26) are preferably positioned at portions of the shaped side wall portion (12) that are anticipated to need increased strength in order to withstand deformation under pressure. The side wall (12) is then assembled to at least one can end member (30) to form a completed shaped metal can (28). The ribs either is arranged longitudinally, circumferential, or both is provided to form a grid structure
