A tamper-evident thermoplastic fitment (11) having a spout (34) and a closure (12) for said spout are welded to a plastic or plastic-coated container. The fitment and closure are molded simultaneously with a substantial space between them and with an elongated runner (42) connecting them. 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 mold core. The runner comprises a tear tab which slides through an apertured space (27) on the closure. When the parts engage, tangs (44) on the tear tab engage the space (27), making the assembly tamper-evident. The fitment has a flange (31) which may be welded or otherwise secured to the container. The tab may be pulled by the consumer to open the container. The closure may be unscrewed from the spout or otherwise disengaged. |
