A flip-top closure includes first and second polymeric closure portions. The first closure portion includes a top wall portion, a sealing mechanism and an annular skirt portion. The second closure portion includes a tamper-evident band. The closure portions are attached by a line of weakness. The closure portions are further attached via a hinge. The hinge includes a locking tab, a flexible tab and linking segments. The locking tab extends further outwardly from a center of the closure in a closed position than the flexible tab and the linking segments. During the opening of the flip-top closure, the locking tab moves and passes the flexible tab such that the flip-top closure locks in a fully open position.

Flip-top closure

A flip-top closure includes first and second closure portions. The first closure portion includes a polymeric top wall portion, a sealing mechanism, and a polymeric annular skirt portion depending from the top wall portion. The skirt portion includes an internal thread formation for mating with a container. The second closure portion includes a polymeric tamper-evident band depending from and being partially detachably connected to the skirt portion by a frangible connection. The frangible connection extends partially around the periphery of the closure. The first and second closure portions are attached via at least one hinge. The at least one hinge assists in moving the closure between an open and closed positions after the frangible connection has been broken.
