Abstract

A closure having a stopping mechanism whereby a stop lug is positionable between a flexed and unflexed position relative to a spring gap. The stop lug may project from a skirt of the closure top wall. The spring gap is positioned adjacent the stop lug to provide an area for the stop lug to travel when outside forces are applied to the stop lug and subsequently return back to the unflexed position. The stop lug may have a substantially vertical support rib in combination with a plurality of annularly spaced ribs.

Claims

1. A closure comprising:

a closure body having a top wall with a projecting skirt;

said skirt having a rotational stop lug and a spring gap, wherein said stop lug projects from said skirt adjacent to said spring gap, wherein said stop lug radially flexes along said skirt between a flexed position into said spring gap and an unflexed position out of said spring gap; and

said spring gap being substantially open when said stop lug is in said unflexed position and said spring gap being substantially closed when said stop lug is in said flexed position.

2. The closure as in claim 1 wherein said spring gap being a first annular distance when substantially open and a second annular distance when substantially closed, said second annular distance is smaller than said first annular distance.

3. The closure as in claim 1 wherein said stop lug positioned annularly adjacent to said spring gap.

4. The closure as in claim 1 wherein at least one thread projects from said projecting skirt.

5. The closure as in claim 1 wherein said spring gap is a recess in said skirt.

6. The closure as in claim 5 wherein said recess radially extends partially through a portion of said skirt, wherein said skirt has a first radial thickness and said recess reduces said first radial thickness to a smaller second radial thickness.

7. The closure as in claim 5 wherein said recess radially extends entirely through said skirt.

8. The closure as in claim 5 wherein said recess extends from a distal end of said skirt towards said top wall.

9. The closure as in claim 1 wherein said stop lug extends outward from said projecting skirt.

10. The closure as in claim 1 wherein said closure body is a double shell closure and said projecting skirt is an inner shell.

11. The closure as in claim 1 wherein said spring gap annularly spaces said stop lug from an abutment surface of said skirt, wherein said stop lug engages said abutment surface when said stop lug is in said flexed position and said stop lug is disengaged from said abutment surface when said stop lug is in said unflexed position.

12. The closure as in claim 1 wherein said spring gap is a deformable bridge.

13. The closure as in claim 1 is a dispensing closure.

14. The closure as in claim 1 is a child resistant closure.

15. The closure as in claim 1 further including one or more projections depending from said top wall within said skirt, said one or more projections operably positioning a liner within said closure.

16. The closure as in claim 15 wherein said one or more projections is annularly positioned on said top wall.

17. The closure as in claim 15 wherein at least one of said one or more projections is V-shaped in vertical cross section.

18. A closure comprising:

a top wall with a downwardly depending skirt;

at least one thread projecting from said depending skirt;

a rotational stop lug extending outward from said depending skirt and adjacent a spring gap formed in said depending skirt;

said spring gap being a recess extending from a distal end of said skirt upwardly towards said top wall; and

said stop lug being substantially resilient to radially flex along said skirt into and out of a portion of said spring gap.

19. The closure as in claim 18 wherein said recess radially extends through said skirt.

20. The closure as in claim 18 wherein said skirt having a substantially rigid abutment surface adjacent said spring gap and opposite said stop lug.

21. The closure as in claim 20 wherein said spring gap further including a bridge connecting said abutment surface to said stop lug, wherein said bridge is substantially resilient.

22. The closure as in claim 18 wherein said skirt is an inner shell.

23. The closure as in claim 18 wherein said stop lug has a substantially vertical support rib extending towards said top wall.

24. A closure comprising:

a top wall with a downwardly depending outer skirt and inner skirt, said inner skirt having an inner surface facing inward toward the center of said closure and an outer surface facing outward away from the center of said closure;

a rotational top lug extending outward from said inner skirt;

a spring gap adjacent said stop lug permitting radially flexing along said skirt of said stop lug into a portion of said spring gap; and

a rib depending from said top wall and extending substantially vertical along said outer surface of said depending inner skirt and said stop lug.

25. The closure as in claim 24 wherein said vertical rib is one of a plurality of vertical ribs positioned annularly about said outer surface of said inner skirt.

26. The closure as in claim 24 wherein said spring gap is a bridge having a radial cross section that is less than said inner skirt.

27. The closure as in claim 24 wherein said spring gap is a recess extending upwardly from a distal end of said inner skirt.

28. The closure as in claim 27 wherein said recess radially extends entirely through said inner skirt.

29. The closure as in claim 24 wherein said stop lug annularly flexes between an unflexed position and a flexed position, wherein said stop lug reduces an annular distance of said spring gap when said stop lug is in said flexed position.

30. The closure as in claim 24 is a child resistant closure.

31. The closure as in claim 28 wherein said outer skirt is a first, second, third, and fourth side wall substantially forming a rectangular shape and having at least a first and a second conjoined surface, said first and second conjoined surface being a recessed squeeze pad on opposing sides of said closure.
