A container end is provided so that upon opening, a generally triangular vent region is formed with an apex pointing rearwardly 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 (relative to certain previous configurations) in the opening area and achieves a superior pour without increased bursting, buckling or opening failures associated with relatively larger openings. |
