Abstract

A closure that remains coupled to a container after the upper portion of the closure has been rotatably removed from the container. The closure may include an attachment channel, which includes alternating segments of linear openings and frangible connections. The attachment channel may also include two hinge bridges that remain unbroken when one or more of the frangible connections are broken.

First claim

I claim:

1. A twist and flip closure comprising:
a first closure portion including:
a polymeric top wall portion,
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; and
a second closure portion including:
a polymeric tamper-evident band depending from and being partially detachably connected to the polymeric annular skirt portion by a first frangible connection,
the first frangible connection extending around the circumference of the closure, the first frangible connection having a first end and a second end, the first end and the second end being spaced apart,
a second frangible connection having a first section and a second section, the first section being located a first distance from the top wall portion, the second section being located a second distance from the top wall portion, the second distance being greater than the first distance, the second frangible connection being spaced from the first frangible connection, at least a portion of the second frangible connection being located further from the top wall portion than a portion of the first frangible connection, the first and second sections of the second frangible connection defining an area that is adapted to form a tab, the area adapted to form the tab being between the first and second ends of the first frangible connection in an unopened position;
wherein the closure is adapted to be opened by twisting so as to break the first and second frangible connections and expose the tab and then flipping the first closure portion from the second closure portion via the tab,
wherein the closure is adapted to be locked via the tab during the flipping of the first closure portion from the second closure portion.

2. The closure of claim 1 , wherein the first closure portion further includes a polymeric continuous plug seal depending from the polymeric top wall portion.

3. The closure of claim 1 , wherein the shape of the closure is generally cylindrical and is a one-piece closure.

4. A twist and flip closure comprising:
a first closure portion including:
a polymeric top wall portion,
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; and
a second closure portion including:
a polymeric tamper-evident band depending from and being partially detachably connected to the polymeric annular skirt portion by a first frangible connection,
the first frangible connection extending around the circumference of the closure, the first frangible connection having a first end and a second end, the first end and the second end being spaced apart,
a second frangible connection having a first section and a second section, the first section being located a first distance from the top wall portion, the second section being located a second distance from the top wall portion, the second distance being greater than the first distance, the second frangible connection being spaced from the first frangible connection, at least a portion of the second frangible connection being located further from the top wall portion than a portion of the first frangible connection, the first and second sections of the second frangible connection defining an area that is adapted to form a tab, the area adapted to form the tab being between the first and second ends of the first frangible connection in an unopened position;
wherein the closure is adapted to be opened by twisting so as to break the first and second frangible connections and expose the tab and then flipping the first closure portion from the second closure portion via the tab,
wherein the closure is adapted to be locked via the tab during the flipping of the first closure portion from the second closure portion; and
wherein the first frangible connection extends around the circumference of the closure from about 280 to about 330 degrees.

5. The closure of claim 4 , wherein the first frangible connection extends around the circumference of the closure from about 300 to about 325 degrees.

6. The closure of claim 1 , wherein an area between the first frangible connection and the second frangible connection forms hinged areas to assist in moving and locking the tab.

7. 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 twist and flip closure being configured for fitment to the neck portion of the container for closing the opening, the twist and flip closure comprising a first closure portion and a second closure portion, the 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 the external thread formation of the container, the second closure portion including a polymeric tamper-evident band depending from and being partially detachably connected to the polymeric annular skirt portion by a first frangible connection, the first frangible connection extending around the circumference of the closure, the first frangible connection having a first end and a second end, the first end and the second end being spaced apart, the second closure portion further including a second frangible connection, the second frangible connection having a first section and a second section, the first section being located a first distance from the top wall portion, the second section being located a second distance from the top wall portion, the second distance being greater than the first distance, the second frangible connection being spaced from the first frangible connection, at least a portion of the second frangible connection being located further from the top wall portion than a portion of the first frangible connection, the first and second sections of the second frangible connection defining an area that is adapted to form a tab, the area adapted to form the tab being between the first and second ends of the first frangible connection in an unopened position,
wherein the closure is adapted to be opened by twisting so as to break the first and second frangible connections and expose the tab and then flipping the first closure portion from the second closure portion via the tab,
wherein the closure is adapted to be locked via the tab during the flipping of the first closure portion from the second closure portion.

8. 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 twist and flip closure being configured for fitment to the neck portion of the container for closing the opening, the twist and flip closure comprising a first closure portion and a second closure portion, the 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 the external thread formation of the container, the second closure portion including a polymeric tamper-evident band depending from and being partially detachably connected to the polymeric annular skirt portion by a first frangible connection, the first frangible connection extending around the circumference of the closure, the first frangible connection having a first end and a second end, the first end and the second end being spaced apart, the second closure portion fur
