1. A flip-top closure comprising:
a first closure portion including:
a polymeric top wall portion,
a sealing mechanism depending from the polymeric top wall portion, and
a polymeric annular skirt portion; and
a second closure portion including:
a polymeric tamper-evident band,
wherein the first closure portion and the second closure portion are attached by a line of weakness,
wherein the first closure portion and the second closure portion are further attached via a hinge, the hinge assisting in moving the flip-top closure between an open position and a closed position, the hinge including a polymeric locking tab, a polymeric flexible tab and a plurality of polymeric linking segments, the polymeric locking tab extending further outwardly from a center of the flip-top closure in the closed position than the polymeric flexible tab and the plurality of polymeric linking segments, the polymeric flexible tab having a flat outer surface with a convex upper surface,
wherein during opening of the flip-top closure, the polymeric locking tab is configured to move and pass the convex upper surface of the polymeric flexible tab such that the flip-top closure locks in a fully open position in which the polymeric locking tab is configured to contact a finish of a container.
