Abstract
A flip-top closure includes first and second closure portions. The first closure portion includes a top wall portion with a tamper-evident winged section and a middle section, which are connected via a frangible connection. The winged section forms an undercut. The top wall portion includes a drivable structure to assist in threading the flip-top closure into a container. The second closure portion includes an annular skirt portion and a ledge. The annular skirt portion forms an external thread formation. The ledge includes at least one locking protrusion. A hinge connects the first and second closure portions. In an initially closed position, the undercut of the winged section corresponds with and lockingly engages with the locking protrusion. During movement of the hinge from the initially closed position to an open position, the frangible connection breaks leaving the winged section being lockingly engaged with the locking protrusion.
