  • Flip-top closure
    Patent number: 11926451
    Abstract: 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.
