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.

[ What is claimed is:] [1.] A vented container end comprising:a generally flat cover region with a score defining first and second rupture endpoints, wherein at least a portion of said score extending between said first and second rupture endpoints together with a gate axis between said first and second rupture endpoints defines an opening area of said cover region;a tab coupled to said cover region so as to permit said tab to be moved about a pivot point to press against a contact region of said opening area, the pivot point and contact region generally lying along an opening axis, said pivot point defining a second axis passing through said pivot point and perpendicular to said opening axis;a reinforcing bead, wherein said bead has a first end substantially adjacent said gate axis, and wherein said reinforcing bead lies entirely on one side of said gate axis and does not extend across said gate axis;wherein said first and second rupture endpoints lie on the same side of said second axis and said contact region is on the opposite side of said second axis from said first and second rupture endpoints;wherein said second rupture endpoint is farther from said pivot point than said first rupture endpoint;wherein said second rupture endpoint is farther from said second axis than said first rupture endpoint so that said gate axis is at an angle with respect to said second axis.
