In or relating to tamper-evident closures

1. A tamper-evident closure for a container, the closure comprising a base and a lid, the base is attachable to a container neck, the base comprising a sidewall having a free end, the closure further comprising a tamper-evident drop band, the tamper-evident drop band including an annular band, the annular band being frangibly connected to said free end of said sidewall, the tamper-evident drop band further comprising a flap that extends radially inwards of the annular band when the closure is fitted onto a container neck, the flap including an abutment for engaging the container neck to cause the tamper-evident drop band to break away from the sidewall if an attempt is made to remove the closure from the neck once fitted, the flap further comprising an extension against which the base sidewall abuts if the closure is reapplied and pushes or holds the annular band away from the free end of the base sidewall to form and maintain a gap therebetween.

2. A closure as claimed in claim 1 , in which the sidewall comprises an internal bead for pushing the extension in the reapplied position.

3. A closure as claimed in claim 2 , in which part of the extension is initially located above the bead and is pulled down over the bead upon removal of the closure, and thereafter cannot pass back over the bead.

4. A closure as claimed in claim 2 , in which the internal bead is continuous or discontinuous.

5. A closure as claimed in claim 1 , in which the extension comprises a plurality of flaps.

6. A closure as claimed in claim 1 , in which the band is pushed so that the band is pressed against a container neck transfer bead.

7. A closure as claimed in claim 1 , in which the band is formed with the flap in an unfolded position.

8. A closure as claimed in claim 1 , in which the lid is hingedly connected to the base.

9. A closure as claimed in claim 8 , in which there is provided a tamper-evident means for indicating if the lid has been opened.

10. A closure as claimed in claim 1 , in which the base comprises a dispensing member.

11. A closure as claimed in claim 10 , in which the member is a spout.

12. A closure as claimed in claim 10 , in which the member comprises a self-closing valve.

13. A closure as claimed in claim 1 , in which the base is screw threadable onto a neck.

14. A closure as claimed in claim 1 , in which the band comprises anti-rotation means for improving breakage.

15. A container fitted with a closure as claimed in claim 1 .

16. A flip-top sportscap for a container neck, the sportscap comprising a screw-threaded base and a lid joined by a hinge, the base comprising a sidewall at the free end of which a tamper-evident drop-band is frangibly connected, the drop band comprising a folded flap having a part which engages a container neck in use and causes the band to break away from the sidewall if the base is unscrewed, the flap further comprising an extended free end and the sidewall comprising an abutment bead, the bead abutting against the free end of the band to push the band away from the free end of the sidewall if the base is re-screwed onto the neck.

17. A tamper-evident closure for a container, the tamper-evident closure comprising:

a body, the body is attachable to a container neck, the body comprising a sidewall having a free end; and

a tamper-evident drop band, the tamper-evident drop band including an annular band, the annular band being frangibly connected to said free end of said sidewall, the tamper-evident drop band further comprising a flap which extends radially inwards of the annular band when the closure is fitted onto a container neck, the flap including an abutment for engaging the container neck to cause the tamper-evident drop band to break away from the sidewall if an attempt is made to remove the closure from the neck once fitted, the flap further comprising an extension against which the base sidewall pushes if the closure is reapplied and pushes or holds the annular band away from the free end of the base sidewall.
