Japanese Patent JP2003501318
Kind Code:
A closure for a package that is adapted for mounting to a surface of the package includes a mounting flange having substantially planar upper and lower surfaces that define a thickness and define a flange plane. A spout extends from the upper surface of the flange and has an inner wall defining a dispensing opening. A membrane has a central portion and a circumferential edge region and is formed in the spout so as to extend to the inner wall to define a spout seal. The membrane is severable from the spout at the edge region. The edge region is selectively thinned and has a pair of first thickness regions and a pair of second thickness regions interposed between the first thickness regions. The second thickness regions have a thickness that is greater than a thickness of the first thickness regions.
