Snap action tamper evident closure assembly

1. A tamper evident closure for a medical container comprising:

a cover including an access opening and an oppositely disposed closed-end,

a tip cap structured and configured to be attached to the medical container and removably disposed within said cover,

a first snap structure disposed within said cover and a second snap structure disposed on said tip cap, initially within said cover,

said first snap structure integrally and fixedly connected to an inner surface of said cover; said second snap structure integrally and fixedly connected to an outer surface of said tip cap,

said first and second snap structures cooperatively disposed and configured to removably restrict exiting of said tip cap from said cover, via said access opening,

each of said first and second snap structures including an angled segment disposed in sliding engagement with one another, concurrent to said exiting of said tip cap, via said access opening, and

each of said first and second snap structures further including a stop segment disposable in abutting, insertion preventive engagement with one another, concurrent to reentry of said tip cap within said cover.

2. The tamper evident closure as recited in claim 1 wherein said cover is dimensioned and configured to define an outward flexure thereof, concurrent to said sliding engagement of said angled segments; said outward flexure defining a snap-action disconnection of said tip cap from said cover.

3. The tamper evident closure as recited in claim 1 wherein said angled segments of said first and second snap structures are respectively disposed at a substantially 120° angle relative to said inner surface of said cover and said outer surface of said tip cap.

4. The tamper evident closure as recited in claim 1 wherein said stop segment of each of said first and said second snap segments is respectively disposed in substantially perpendicular relation to said inner surface of said cover and said outer surface of said tip cap.

5. The tamper evident closure as recited in claim 1 wherein said first and second snap structures are fixedly connected to and movable with said cover and said tip cap respectively.

6. The tamper evident of closure as recited in claim 1 when at least one of said first and second snap structures comprises a substantially annular configuration.

7. The tamper evident closure as recited in claim 1 wherein said tip cap and said second snap structure are collectively dimensioned to pass through said access opening, concurrent to said exiting of said tip cap.

8. A tamper evident closure for a medical container comprising:

a cover including an access opening and an oppositely disposed closed-end,

a tip cap structured and configured to be attached to the medical container and removably disposed within said cover,

an indicator member movably disposed within said cover, initially in an exit restricting relation to said tip cap,

a first snap structure integrally and fixedly connected to an inner surface of said indicator member; a second snap structure integrally connected to an outer surface of said tip cap,

said exit restricting relation of said of said indicator member with said tip cap comprising said first and second snap structures disposed in removable, sliding engagement with one another,

said indicator member movable within an interior of said cover from a trapped orientation into a captured orientation, subsequent to said removable, sliding engagement between said first and second snap structures and concurrent to said exiting of said tip cap via said access opening, and

said captured orientation comprising said indicator member movably disposed within said interior of said cover, between said access opening and said closed-end.

9. The tamper evident closure as recited in claim 8 wherein said exit restricting relation further comprises said indicator member disposed in a trapped orientation between said tip cap and an interior surface of said cover.

10. The tamper evident closure as recited in claim 9 wherein said indicator member comprises an indicator ring initially disposed in surrounding relation to said tip cap and dimensioned to include an outer diameter greater than an inner diameter of said access opening.

11. The tamper evident closure as recited in claim 8 wherein said cover comprises a shelf structure disposed within said cover, said shelf structure having a smaller inner diameter than an outer diameter of the indicator member; said trapped orientation further comprising said indicator member disposed between said shelf structure and said tip cap, concurrent to said first and second snap structures disposed in said removable sliding engagement with one another.

12. The tamper evident closure as recited in claim 11 wherein said captured orientation further comprises said indicator member movably disposed within said cover, between said shelf and said closed-end.

13. The tamper evident closure as recited in claim 8 wherein each of said first and second snap structures include an angled segment, said angled segments disposed in removable and movable, sliding engagement with one another, concurrent to said exiting of said tip cap, via said access opening.

14. The tamper evident closure as recited in claim 13 wherein said indicator member is dimensioned and structured to define an outward flexure thereof, concurrent to said sliding engagement of said angled segments; said outward flexure defining a snap-action disconnection of said tip cap from said indicator member.
