Abstract

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.

First claim

What is claimed is:

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 exposed 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 2 , wherein the first closure portion further includes an outer seal depending from the polymeric top wall portion.

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

5. The closure of claim 1 , wherein the closure comprises at least one polyolefin.

6. The closure of claim 1 , wherein the first frangible connection extends around the circumference of the closure from about 280 to about 330 degrees.

7. The closure of claim 6 , wherein the first frangible connection extends around the circumference of the closure from about 300 to about 325 degrees.

8. The closure of claim 1 , wherein the second frangible connection extends around the circumference of the closure from about 120 to about 180 degrees.

9. 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.

10. The closure of claim 1 , wherein the first section of the second frangible connection includes two segments and the second section of the second frangible connection includes three segments, the three segments of the second section forming the tab after the second frangible connection is broken.

11. The closure of claim 1 , wherein the first section of the second frangible connection includes two generally horizontal segments and the second section of the second frangible connection includes two generally vertical segments and one generally horizontal segment, the first and second sections being connected with each other.

12. The closure of claim 1 , wherein a portion of the second frangible connection is a generally U-shape.

13. The closure of claim 1 , wherein the entire second frangible connection is located further from the top wall portion than the first frangible connection.

14. 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 polymeric tamper-evident band including at least one band extension, the at least one band extension assisting in positioning the first closure portion in a locked position after flipping,
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, an area between the first frangible connection and the second frangible connection forming hinged areas to assist in moving and locking the tab;

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 exposed 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.

15. The closure of claim 14 , wherein the first frangible connection extends around the circumference of the closure from about 280 to about 330 degrees.

16. The closure of claim 14 , wherein the second frangible connection extends around the circumference of the closure from about 120 to about 180 degrees.

17. The closure of claim 14 , wherein the first section of the second frangible connection includes two segments and the second section of the second frangible connection includes three segments, the three segments of the second section forming the tab after the second frangible connection is broken.

18. The closure of claim 14 , wherein a portion of the second frangible connection is a generally U-shape.

19. The closure of claim 14 , wherein the entire second frangible connection is located further from the top wall portion than the first frangible connection.

20. 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 in
