摘要：A container end is provided so that upon opening, a generally triangular ventregion is formed with an apex pointing rearwardly toward the head space to vent thecontainer, e.g. during pouring. A container is provided that achieves a fast and smoothpour with a relatively small increase (relative to certain previous configurations) in theopening area and achieves a superior pour without increased bursting, buckling oropening failures associated with relatively larger openings.
