Abstract

A closure for a fitment is provided with an outer side wall extending downwardly therefrom and spaced from an inner sealing ring wherein the outer side wall adjacent the top wall is provided with a plurality of spaced inwardly extending ribs, adapted for embedding into a lip at the outlet of a fitment neck.

Claims

1. A closure for a fitment for a container comprising:

a top wall, an outer side wall extending downwardly therefrom and an inner sealing ring spaced inwardly from said side wall, the outer side wall having circumferentially spaced vertically extending ribs along an upper inner surface adjacent said top wall, the inner sealing ring having a lower terminating edge engagable with a lip of a fitment neck, the spacing between an upper portion of said ribs and an upper portion of an outer surface of said sealing ring being less than the thickness of said fitment neck.

2. The closure of claim 1, said vertically extending ribs having outer edges angled downwardly in a direction towards an inner surface of said outer side wall.

3. The closure of claim 2, the spacing between lower terminating edges of said outer edges of said ribs and said outer surface of said sealing ring being greater than the thickness of said container neck.

4. The closure of claim 1, said lower terminating edge of said sealing ring being beveled.

5. The closure of claim 1, said top wall having a downwardly extending flanged portion spaced between said upper portion of said rib and said outer surface of said inner sealing ring.

6. The closure of claim 1, said closure having at least one thread disposed circumferentially along an inner surface of said outer wall.

7. The closure of claim 1, said fitment being unitary with said container.

8. A closure in combination with a fitment for a container comprising:

said fitment having a fitment neck;

said closure having a top wall with an outer side wall extending downwardly therefrom and an inner sealing ring spaced inwardly from said side wall, the outer side wall having circumferentially spaced vertically extending ribs along an upper inner surface adjacent said top wall, the inner sealing ring having a lower terminating edge engagable with a lip of a fitment neck inner surface, the spacing between an upper portion of said ribs and an upper portion of an outer surface of said sealing ring being less than the thickness of said fitment neck.

9. The combination of claim 8, said vertically extending ribs having outer edges angled downwardly in a direction towards an inner surface of said outer side wall.

10. The combination of claim 9, the spacing between lower terminating edges of said outer edges of said ribs and said outer surface of said sealing ring being greater than the thickness of said container neck.

11. The combination of claim 8, said lower terminating edge of said sealing ring being beveled.

12. The combination of claim 8, said top wall having a downwardly extending flanged portion spaced between said upper portion of said rib and said outer surface of said inner sealing ring.

13. The combination of claim 8, said closure having at least one thread disposed circumferentially along an inner surface of said outer wall.

14. The combination of claim 8, said fitment being unitary with said container.

15. The combination of claim 8, said closure and said fitment being made of plastic materials, said closure being of a harder plastic material than said fitment.

16. A closure and container combination, comprising:

a container neck extending upward and having at least one thread formed thereon;

a closure threadably engaging said container neck, said closure having a top wall and a depending annular side wall, said side wall having at least one thread thereon and a depending annular seal, said closure also having an defined area about the joinder of said side wall and said top wall, said defined area populated with a plurality of abutments thereby forming a decreased width between said plurality of abutments and said annular seal wherein said decreased width is less than the thickness of said container neck.

17. A closure for a fitment, comprising:

a fitment having an upstanding neck and at least one thread formed thereon;

a closure having a top wall and a depending annular side wall with at least one thread on an interior surface thereof, a plurality of ribs formed along an interior area defined by the joining of said side wall and said top wall, said ribs being substantially vertically extending, said closure further having a seal depending from said top wall and spaced interiorly from said plurality of ribs;

wherein said ribs cause a top portion of said upstanding neck to be compressed between said ribs and said seal.

18. A closure for a fitment, comprising:

a fitment having an upstanding neck and at least one thread formed thereon;

a closure having a top wall and a depending annular side wall with at least one thread on an interior surface thereof, a plurality of ribs formed along an interior area defined by the joining of said side wall and said top wall, said ribs being substantially vertically extending, said closure further having a seal depending from said top wall and spaced interiorly from said plurality of ribs and further said top wall having a downwardly extending flanged portion between said plurality of ribs and said seal;

wherein said ribs cause a top portion of said upstanding neck to be compressed between said ribs and said seal.
