IMPROVEMENTS IN AND RELATING TO TAMPER EVIDENT SEALS

摘要

A tamper evident seal for a container includes a screw thread and a closure means adapted for use with the container. The tamper evident seal comprises a normally circular ring which is frangibly linked to the closure means. The ring has one or more inwardly extending protrusions, and the container has one or more corresponding outwardly extending protrusions adjacent its screw thread. The faces of the protrusions are configured such that the leading face of the or each ring protrusion approaches the forward face of the or each container protrusion when the closure means is being fitted onto the container. Any protrusions on the container or ring are situated or grouped in spaced apart locations about a perimeter of the container or ring and the normally circular ring is able to pass over the protrusion or protrusions on the container substantially without stretching and by deforming out of round. The closure means is also adapted for use as a drinking vessel and the container is substantially bottle shaped.
