ABSTRACT:
A device for attaching a fitment to an open mouth container and for tamper-evident sealing of the fitment with the fitment attached thereto. The device includes a closure portion having a first skirt portion adapted for rolling a thread to engage a cooperating thread on the fitment. Other skirt portions are adapted for rolling such portions into engagement with the fitment and the container to firmly attach the fitment to the container, and a fracturable line of weakening is provided between the first skirt portion and the other skirt portions to provide evidence that the container has been opened upon a first unthreading of the closure.
