ABSTRACT:
A fitment for a container, such as a carton, has an attachment flange adapted to be sealed to the carton around a pour hole therein. The fitment has a cylindrical spout formed with vertically spaced seal bead and locking bead. The closure has a top disk with a depending skirt dimensioned to slidably fit within the spout. The exterior of the skirt has an external locking bead at its lower end positioned to lock under the fitment locking bead to hold the closure in place and a seal surface to be engaged by the fitment seal bead. Initially the fitment and spout are molded as a unit, the locking bead of the closure and the top edge of the fitment spout being joined by a circular frangible link. The combination is tamper-evident since access to the interior of the carton cannot be obtained without breaking the link. As an alternative, the cap may be separated from the spout and slid inside the spout. Separate cooperable means on the cap disk and fitment flange make this alternative tamper-evident.
