ABSTRACT:
A fitment attached around an aperture in a container has a flange from which extends an internally threaded spout closed by an initially integrally molded externally threaded plug. The plug is moved axially into the spout, the threads slipping over each other. The plug has an outward extending slotted ear and the fitment has an upward extending finger aligned with the slot in the ear and formed with tangs which lock the finger and ear together as the plug is moved to the spout, thereby making the device tamper-evident. As a further feature of the invention, an over-size foil seal extends across the bottom of the flange and is welded or otherwise adhered to the bottom of the flange. After assembly the portion of the foil extending outside the flange is welded or otherwise adhered to the carton. This further feature is particularly useful in aseptic packaging. Optionally the lower edge of the plug may be welded to the foil so that when the consumer unscrews the plug the foil under the spout is torn away.
