Abstract (en)
[origin: WO9712813A1] A tamper-evident thermoplastic fitment (11a) having a spout (34a) and a closure (12) for said spout are welded to a polymer-coated paperboard or to a flexible plastic container via a flange (31a). The fitment and closure are molded simultaneously but with a substantial space between them. They are interconnected by elongates runner (42a) which is formed when molten plastic is conducted from the closure to the fitment. Upon retraction of the mold core, the closure is pulled into the spout until shoulders on the parts engage, whereupon the closure is stripped from the core. The runer comprises a tear tab which slides through an aperture (28) on the closure. When the parts engage, tangs (44a) on the tear tab slip through the aperture, making the assembly tamper-evident. The tab may be pulled by the consumer to open the container. The closure may be unscrewed from the spout.
