Twist and flip lock closure
A twist and flip closure includes first and second closure portions. The first closure portion includes a top wall portion, a skirt portion, and first and second frangible connections. The first frangible connection extends around the closure circumference. The second frangible connection has first and second sections. The second frangible connection is spaced from the first frangible connection. At least a portion of the second frangible connection is located further from the top wall portion than a portion of the first frangible connection. The second frangible connection defines an area adapted to form a tab. The second closure portion includes a tamper-evident band. The closure is adapted to be opened by twisting to break the frangible connections and expose the tab and then flipping the first closure portion from the second closure portion via the exposed tab. The closure is adapted to be locked when flipped.
1. A package comprising:
a container having a neck portion defining an opening, the container having an external thread formation on the neck portion; and
a closure being configured for fitment to the neck portion of the container for closing the opening, the closure comprising:
a first closure portion including:
a polymeric top wall portion, and
a polymeric annular skirt portion depending from the polymeric top wall portion, the annular skirt portion including an internal thread formation for mating engagement with an external thread formation of a container;
a second closure portion including:
a first frangible connection extending around the circumference of the closure from about 280 degrees to about 330 degrees, the first frangible connection having a first end and a second end defining a gap therebetween, the gap extending from about 30 degrees to 80 degrees around the circumference of the closure, the first frangible connection spaced from about 7 mm to about 14 mm from the top wall portion and spaced from about 5 mm to 12 mm from an end opposite the top wall portion;

7. The package of claim 1 , wherein the first frangible connection is spaced from about 6 mm to about 9 mm from an end opposite the top wall portion.
8. The package of claim 1 , wherein the second frangible connection is spaced from about 9 mm to about 12 mm from the top wall portion.
9. The package of claim 1 , wherein the second frangible connection extends around the circumference of the closure from about 130 to about 170 degrees.
10. The package of claim 1 , wherein the first frangible connection extends around the circumference of the closure from about 300 degrees to about 325 degrees.
11. A package comprising:
a container having a neck portion defining an opening, the container having an external thread formation on the neck portion; and
a closure being configured for fitment to the neck portion of the container for closing the opening, the closure comprising:
a first closure portion including:
a polymeric top wall portion, and
a polymeric annular skirt portion depending from the polymeric top wall portion, the annular skirt portion including an internal thread formation for mating engagement with an external thread formation of a container;
a second closure portion including:
a first frangible connection extending around the circumference of the closure from about 280 degrees to about 330 degrees, the first frangible connection having a first end and a second end defining a gap therebetween, the gap extending from about 30 degrees to 80 degrees around the circumference of the closure, the first frangible connection spaced from about 7 mm to about 14 mm from the top wall portion and spaced from about 5 mm to 12 mm from an end opposite the top wall portion;
a second frangible connection extending around the circumference of the closure from about 120 degrees to about 180 degrees, the second frangible connection spaced from about 8 mm to about 16 mm from the top wall portion, the second frangible connection spaced further from the top wall portion than the first frangible connection;
wherein areas formed between the first frangible connection and the second frangible connection form hinged arms after the first and second frangible connections are broken,
wherein the closure is configured to lock after being moved to an open position.
12. The package of claim 11 , wherein the hinged arms keep the first closure portion and the second closure portion together.
13. The package of claim 12 , wherein the hinged arms are sized and shaped to be twisted and stretched.
