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.
Claims20
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 the open position and the closed position, the hinge including a polymeric locking tab, a polymeric flexible tab, and a plurality of polymeric linking segments, the polymeric locking tab having a raised portion relative to a remainder of the hinge, the polymeric locking tab extending further outwardly from a center of the flip-top closure in a closed position than the polymeric flexible tab and the plurality of polymeric linking segments,
- wherein during the opening of the flip-top closure, the polymeric locking tab is configured to move and pass the polymeric flexible tab such that the flip-top closure locks in a fully open position such that the polymeric locking tab is configured to contact a top surface of a container and the polymeric flexible tab.
A package comprising:
- a container having a neck portion defining an opening, the container having an outwardly-extending projection on the neck portion;
- and
- a flip-top closure being configured to be secured to the neck portion of the container, the flip-top closure including a first closure portion and a second closure portion, the 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, the 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 the open position and the closed position, the hinge including a polymeric locking tab, a polymeric flexible tab and a plurality of polymeric linking segments, the polymeric locking tab having a raised portion relative to a remainder of the hinge, the polymeric locking tab extending further outwardly from a center of the flip-top closure in a closed position than the polymeric flexible tab and the plurality of polymeric linking segments,
- wherein during the opening of the flip-top closure, the polymeric locking tab is configured to move and pass the polymeric flexible tab such that the flip-top closure locks in a fully open position such that the polymeric locking tab is configured to contact the neck portion of the container and the polymeric flexible tab.
