ABSTRACT:
A fitment attached around an aperture in a container has a flange from which extends a spout closed by an initially integrally molded externally threaded plug. So long as the fitment and plug are in their original position after molding, the combination is tamper-evident. The plug is moved axially into the spout, with a liquid-tight fit. The plug has an outward extending tab formed with a slot and the fitment has an upward extending finger aligned with the slot in the tab and formed with tangs which lock the finger and tab together as the plug is moved into the spout, thereby making the device tamper-evident. A characteristic of the invention is that a tether interconnects the plug and the upper edge of the spout to prevent disconnection of the one from the other. 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.
