| 20080231922 | CONTAINER SEAL WITH REMOVAL TAB AND HOLOGRAPHIC SECURITY RING SEAL - A holographic sealing member for a container is designed for attachment to the rim of an opening in the container. The holographic sealing member comprises a holographic layer having an upper plastic layer on its upper side and a lower embossed image layer on its lower side. A sealant or adhesive layer is attached to at least those portions of the lower side of the holographic layer that are intended to come into direct contact with the container's rim when the sealing member is placed upon and is sealed to a container.
