Title:
VENTED CONTAINER END APPARATUS AND METHOD
Document Type and Number:
WIPO Patent Application WO2000056613
Kind Code:
A8
Abstract:
A container end is provided so that upon opening, a generally triangular vent region (362) is formed with an apex pointing rearwardly toward the head space to vent the container during pouring. The container end achieves a fast and smooth pour with a relatively small increase in the opening area (322) without increased bursting, buckling or opening failures associated with relatively larger openings. The opening area is defined by a score line (318) having first (342) and second (346) rupture end points with a gate axis (348) therebetween along which the opening area (322) pivots after rupture of the score line (318).
