Abstract

A package includes a container and closure. The container has a neck portion defining an opening. The container has an external thread formation and catch lugs. The closure fits to the neck portion for closing the opening. The closure includes first and second closure portions. The first closure portion includes a top wall portion and a skirt portion. The skirt portion depends from the top wall portion. The skirt portion includes an internal thread formation for mating engagement with the external thread formation. The second closure portion includes a tamper-evident band depending from and being partially detachably connected to the skirt portion by a frangible connection. An interior surface of the second closure portion includes catch teeth. The catch lugs mechanically catch and lock with a respective one of the catch teeth to prevent or inhibit the second closure portion from being removed during the opening of the container.

First claim

What is claimed is:

1. A package comprising:
a container having a neck portion defining an opening, the neck portion having an exterior surface and an interior surface, the container having an external thread formation and a plurality of catch lugs being located on the exterior surface of 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 and a second closure portion, the first closure portion including a polymeric top wall portion and a polymeric annular skirt portion, the polymeric annular skirt portion depending from the polymeric top wall portion, the polymeric 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 frangible connection, the frangible connection extending around the circumference of the closure, the second closure portion having an exterior surface and an interior surface, the interior surface of the second closure portion including a plurality of catch teeth, at least one of the plurality of catch lugs of the container configured to mechanically catch and lock with a respective one of the plurality of catch teeth of the second closure portion so as to prevent or inhibit the second closure portion from being removed during the opening of the container;
wherein each of the plurality of catch teeth has a first end and a second end, each of the first ends of the plurality of catch teeth having a height and a width greater than a height and a width of the second end, the height and the width of the plurality of catch teeth being tapered from the first end to the second end, the plurality of catch teeth having a length extending along an interior surface of the polymeric tamper-evident band, the length of the plurality of catch teeth being greater than the width of the first end and the width of the second end, the plurality of catch teeth being greater than the height of the first end and the height of the second end.

2. The package of claim 1 , wherein the container further includes a retention channel, the retention channel being located on the exterior surface of the neck portion, the retention channel being located between the external thread formation and the plurality of catch lugs,
wherein the closure further includes a plurality of retention tabs, the plurality of retention tabs being located on the interior surface of the second closure portion, the plurality of retention tabs being located between the frangible connection and the plurality of catch teeth,
wherein the plurality of retention tabs of the closure is configured to engage with the retention channel of the container.

3. The package of claim 2 , wherein the neck portion of the container further includes a continuous outer ring and an A-collar, the continuous outer ring and the A-collar assisting in forming the retention channel.

4. The package of claim 2 , wherein the retention channel extends around the entire circumference of the neck portion of the container.

5. The package of claim 2 , wherein the plurality of retention tabs is at an angle of from about 30 to about 60 degrees relative to the tamper-evident band and extending upwardly towards the polymeric top wall portion.

6. The package of claim 1 , wherein the closure further includes a liner, the liner being located adjacent to an interior surface of the polymeric top wall portion.

7. The package of claim 1 , wherein the external thread formation of the container is one continuous helical thread, and wherein the internal thread formation of the closure is one continuous helical thread.

8. The package of claim 1 , wherein the length of the plurality of catch teeth is from about 0.2 to about 0.75 inch, the height of the first end is from about 0.05 inch to about 0.10 inch, and the width of the first end is from about 0.02 to about 0.063 inch.

9. The package of claim 1 , wherein each of the first ends of the plurality of catch teeth has a surface being angled inwardly, at least one of the surfaces of the first end of the plurality of catch teeth being configured to mechanically catch and lock with a respective one of the plurality of catch teeth.

10. The package of claim 1 , wherein the frangible connection is formed by molded-in-bridges.

11. A package comprising:
a container having a neck portion defining an opening, the neck portion having an exterior surface and an interior surface, the container having an external thread formation and a plurality of catch lugs being located on the exterior surface of 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 and a second closure portion, the first closure portion including a polymeric top wall portion and a polymeric annular skirt portion, the polymeric annular skirt portion depending from the polymeric top wall portion, the polymeric 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 frangible connection, the frangible connection extending around the circumference of the closure, the second closure portion having an exterior surface and an interior surface, the interior surface of the second closure portion including a plurality of catch teeth, at least one of the plurality of catch lugs of the container configured to mechanically catch and lock with a respective one of the plurality of catch teeth of the second closure portion so as to prevent or inhibit the second closure portion from being removed during the opening of the container,
wherein each of the plurality of catch lugs has a first end and a second end, each of the first ends of the plurality of catch lugs having a surface being angled inwardly, each of the first ends of the plurality of catch lugs having a height and a width greater than a height and a width of the second ends, the height and the width of the plurality of catch lugs being tapered from the first end to the second end.

12. The package of claim 1 , wherein the number of catch teeth is from about 4 to about 20, and wherein the number of catch lugs is from about 4 to about 20.

13. The package of claim 12 , wherein the number of catch teeth is from about 6 to about 18, and wherein the number of catch lugs is from about 6 to about 18.

14. The package of claim 1 , wherein each of the plurality of catch lugs of the container is configured to mechanically catch and lock with a respective one of the plurality of catch teeth of the second closure portion so as to prevent or inhibit the second closure portion from being removed during the opening of the container.

15. A package comprising:
a container having a neck portion defining an opening, the neck portion having an exterior surface and an interior surface, the container having an external thread formation, a plurality of catch lugs, and a retention channel being located on the exterior surface of the neck portion, the retention channel being located between the external thread formation and the plurality of catch lugs, the neck portion further including a continuous outer ring and an A-collar, the continuous outer ring and the A-collar assisting
