VENTED CONTAINER END APPARATUS AND METHOD

摘要

A container end is provided so that upon opening, a generally triangular vent region (862) is formed with an apex (872) pointing rearwardly (272) toward the head space to vent the container, e.g. during pouring. A container is provided that achieves a fast and smooth pour with a relatively small increase in the opening area (822) relative to previous configurations and achieves a superior pour without increased bursting, buckling or opening failures associated with relatively larger openings.
