Tamper-evident closure

1. A tamper evident closure for a container, said tamper evident closure comprising:

(a) a first portion, said first portion further comprising:

(i) an inner part;

(ii) an outer part; and

(b) a second portion, wherein said first portion and said second portion are provided in a shell, said shell further comprising:

(i) a first shell part; and

(ii) a second shell part, wherein said outer part is movable relative to said inner part from a first position, in which said first shell part and said second shell part are adjacent each other, to a second position in which there is a gap therebetween;

(c) locking means for locking said tamper evident closure in said second position upon first opening so that said gap cannot easily be closed; and

(d) indicator means arranged such that if said locking means is overridden to close said gap, said indicator means provides a visual identification on said shell that said gap has been closed.

2. A tamper evident closure as claimed in claim 1 , wherein said indicator means are adapted to mark said shell to indicate closing of said gap.

3. A tamper evident closure as claimed in claim 1 , wherein said indicator means are adapted to produce one or more markings on the surface of said tamper evident closure to indicate closing of said gap.

4. A tamper evident closure as claimed in claim 3 , wherein said one or more markings comprise one or more raised formations formed on the shell if the gap is closed.

5. A tamper evident closure as claimed in claim 1 , wherein said shell is deformed to indicate closing of said gap.

6. A tamper evident closure as claimed in claim 5 , wherein said shell is locally weakened to facilitate said deformation.

7. A tamper evident closure as claimed in claim 1 , wherein said indicator means are adapted to puncture the surface of said shell to indicate closing of said gap.

8. A tamper evident closure as claimed in claim 1 , wherein said indicator means also forms part of said locking means.

9. A tamper evident closure as claimed in claim 1 , wherein said locking means is adapted to prevent relative rotation between said inner part and said outer part.

10. A tamper evident closure as claimed in claim 1 , wherein said shell has a top plate and a visual indication is provided on said shell top plate.

11. A tamper evident closure as claimed in claim 1 , wherein said outer part includes a top plate and part of said locking means is carried on or by said top plate.

12. A tamper evident closure as claimed in claim 1 , wherein said inner part further comprises a top plate and part of said locking means is proximate said top plate.

13. A tamper evident closure as claimed in claim 1 , wherein said locking means further comprises a longitudinal ratchet arrangement.

14. A tamper evident closure as claimed in claim 1 , wherein said second shell part is adapted to remain a container and the first part comprises a removable cap.

15. A tamper evident closure as claimed in claim 1 , wherein said closure further comprises an in-bore fitment.

16. A tamper evident closure as claimed in claim 1 , wherein said first portion is adapted to engage an in-bore fitment associated with said container.

17. A tamper evident closure as claimed in claim 1 , wherein said gap is unobstructed.

18. A tamper evident closure as claimed in claim 1 , wherein said inner part further comprises a part which extends beyond said outer part towards said second portion in said second position, said part being positioned so as to be visible through said gap.

19. A tamper evident closure as claimed in claim 1 , wherein said indicator means are adapted to activate following axial overriding of said locking means to close said gap.

20. A tamper evident closure for a container, said tamper evident closure comprising:

(a) a first portion, said first portion further comprising;

(i) an inner part;

(ii) an outer part; and

(b) a second portion, wherein said outer part is movable relative to said inner part from a first position in which at least part of said first and said second portions are adjacent each other to a second position in which there is a gap therebetween;

(c) locking means for locking said tamper evident closure in said second position upon first opening so that said gap cannot easily be closed;

(d) a shell; and

(e) indicator means arranged such that if said locking means is overridden to close said gap, said indicator means provides a visual identification on said shell that said gap has been closed.

21. A tamper-evident closure for a container, said tamper evident closure comprising:

(a) a first portion, said first portion further comprising;

(i) an inner part;

(ii) an outer part relative to said inner part in a first position;

(iii) a lateral ratchet arrangement for locking said inner and said outer parts in a second position; and

(iv) a set of engagement formations and wherein said ratchet arrangement is located above said engagement formations;

(b) a second portion, wherein said outer part is movable relative to said inner part from said first position, in which at least part of said first and said second portions are adjacent each other, to said second position in which there is a gap therebetween;

(c) locking means for locking said tamper evident closure in said second position upon first opening so that said gap cannot easily be closed; and

(d) indicator means arranged such that if said locking means is overridden to close said gap, said indicator means provides a visual identification on said shell that said gap has been closed.
