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. A metal foil layer lies over and covers and is adhesively bonded to the upper side of the holographic layer and may be inductively heated to actuate the heat actuated sealant. A tab covers and is adhesively bonded to the metal foil layer and may be pulled to remove the sealing member from a container. After this sealing member is attached to a container, and when the tab is pulled to remove the sealing member from the container, almost the entire sealing member pulls away from the container, but those portions of the holographic layer's lower embossed image layer that are attached directly to the rim of the container by the sealant or adhesive layer remain attached to the rim of the container to form a hologram that runs around the container's rim.

The holographic sealing member in accordance with claim 1 which further comprises a polyethylene or polypropylene foam or film layer interposed between the metal foil layer and the tab structure. 3. The holographic sealing member in accordance with claim 2 wherein the tab structure comprises: a PET tab defining layer extending over and covering a first portion of, but not bonded to the first portion of, the polyethylene or polypropylene foam or film layer;an EVA layer having an upper and a lower surface, the lower surface bonded to both a second portion of the polyethylene or polypropylene foam or film layer not covered by the PET tab defining layer and to the PET tab defining layer itself, anda second PET layer bonded to the upper surface of the EVA layer. 4. The holographic sealing member in accordance with claim 1 wherein the upper plastic layer of the holographic layer comprises PET and the lower embossed image layer of the holographic layer includes a metal layer. 5. The holographic sealing member in accordance with claim 4 wherein the metal layer of the holographic layer is aluminum. 6. The holographic sealing member in accordance with claim 1 which further comprises a second holographic layer inserted between the holographic layer and the metal foil layer and adhesively bonded to both, the adhesive between the holographic layer and the second holographic layer containing a coloring agent. 7. A holographic sealing member for a container designed for attachment to the land area of a container rim around a container opening, the holographic sealing member comprising: a holographic layer having an upper plastic layer on at its upper side and a lower embossed image layer at its lower side, the upper plastic layer and the lower embossed image layer bonded together with a first bond strength, the bonded upper plastic layer and the lower embossed image layer being separable to provide a splitting point within the holographic layer, and the embossed image layer is configured to tear when the holographic sealing member is removed from the container;a sealant or adhesive layer attached to at least those portions of the lower side of the holographic layer that are in direct contact with the container's rim when the holographic sealing member is placed upon and is sealed to the container, the sealant or adhesive layer effective to bond the holographic layer to a container rim with a second bond strength, wherein the first bond strength is less than the second bond strength;a metal foil layer bonded to the upper side of the holographic layer; anda tab structure bonded to said metal foil layer, the tab structure comprising a tab configured such that the tab can be pulled to remove the holographic sealing member from the container,wherein after said holographic sealing member is attached to the container and when the tab is pulled to remove the holographic sealing member from the container and with the tab structure remaining bonded to the metal foil layer and with the metal foil layer remaining bonded to the upper side of the holographic layer, the holographic sealing member pulls away from the container with the tab structure as the lower embossed image layer tears therethrough adjacent the land area of the container rim so that a portion of the lower embossed image layer above the land area of the container rim separates from the upper plastic layer at the splitting point to leave a portion of the holographic layer's lower embossed image layer attached directly to the land area of the container rim by the sealant or adhesive layer due to the second bond strength being greater than the first bond strength to leave a ring-shaped portion of the lower embossed image layer on the container's rim. 8.
