    Abstract: An applicator for applying surface relief three-dimensional seals or medallions to containers which includes a rotatable transfer ring having a plurality of seal retaining receivers therein formed therein in which plungers are reciprocally mounted. A vaccuum header is associated with the ring so as to create reduced pressure in the receivers for removing seals from a carrier tape and retaining the seals within the receivers as the transfer ring is indexed to align the seals with containers being conveyed relative to the applicator. An activator is provided for urging the plungers from the receivers to thereby apply the seals retained therein against aligned containers.
