Abstract: Lightweight beverage containers disclosed herein require less metal per container, exhibit less earing and have one or more of the following features: 1) a reduced seam between the can end and the can body, 2) a side wall having vertically disposed alternating portions of relatively thicker and relatively thinner metal, 3) a can end dimensioned to fit within the domed bottom of a vertically adjacent similar can when stacked, 4) a can body produced from an acircular blank dimensioned to produce said can body without ears, and 5) a can body produced from a cup having a variable radius between the side of said cup and the bottom thereof.
