Abstract
A bottom end closure for a liquid-carrying paperboard container, wherein particular diagonal and sloped score lines are formed on the inner closure panels by modified sealing jaws, such that, upon being engaged by the sealing jaws, the score lines enhance the formation of a concave shape to the bottom end closure. The result is that the filled container will sit flat and stand erect, without any interfering downward bulging.
