Abstract: A drinking vessel for a liquids packaging product. The drinking vessel is adapted to engage with and seal the opening of a bottle. The drinking vessel incorporates a frangibly linked portion which is adapted to, (a) engage with the bottle when the drinking vessel is fitted to the bottle to seal the bottle, and (b) remain with the bottle when the drinking vessel is subsequently removed from the bottle. Preferably the frangibly linked portion which is adapted to engage with the bottle is in the form of a ring.

Abstract: A tamper evident seal for a container includes a screw thread and a closure adapted for use with the container. The seal comprises a normally circular ring which is frangibly linked to the closure. The ring has one or more inwardly extending protrusions, and the container has one or more corresponding outwardly extending protrusions adjacent its screw thread. Faces of the protrusions are configured such that the leading face of each ring protrusion approaches the forward face of each container protrusion when the closure is fitted onto the container. Protrusions are situated 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 by deforming out of round. The closure is adapted for use as a drinking vessel and the container is substantially bottle shaped.

Abstract: The invention comprises a drinking vessel for a liquids packaging product, the drinking vessel being adapted to engage with and seal the opening of a bottle. The drinking vessel incorporates a frangibly linked portion which is adapted to, (a) engage with the bottle when the drinking vessel is fitted to the bottle to seal the bottle, and to, (b) remain with the bottle when the drinking vessel is subsequently removed from the bottle. Preferably the frangibly linked portion which is adapted to engage with the bottle is in the form of a ring. In a second aspect the invention comprises a liquids packaging product incorporating at least one drinking vessel and at least one bottle adapted to engage with the drinking vessel.
