Abstract (en)
[origin: WO2009023102A1] An internally threaded plastic closure in accordance with the present invention includes an array of axially extending, circumferentially spaced internal ribs which intersect the internal thread formation of the closure. By this arrangement, vent passages are defined between adjacent ones of the internal ribs, thus providing the closure with desirable gas venting characteristics, while avoiding the provision of vent grooves extending into the inside surface of the closure side wall, which can undesirably impair the strength of the side wall. By the present construction, the amount of polymeric material from which the closure is formed can be desirably reduced, while maintaining the desired dimensional characteristics of the closure, to facilitate use with existing containers and high-speed capping equipment.
