Summary for Patent: 5,457,895

Title:	Method of identifying freeze-dried dosage forms
Abstract:	The invention permits the application of an identifying mark onto a freeze-dried tablet without the need for application of pressure or for printing directly on the tablet. The invention comprises the preparation of a freeze-dried unit that is embossed with an identifying mark such as a manufacturer's logo, medicinal component strength, or other information relating to the unit. The desired identifying mark is first embossed onto the base of a container such as a blister pocket. Liquid suspension is then filled into the container and freeze-dried therein. The resulting freeze-dried unit in the container is thereby embossed with substantial copy of the identifying mark that was embossed on the base of the container. The embossed identifying mark on the base of the container remains thereon as well, providing at reduced manufacturing cost the added ability to learn the identifying mark on the enclosed freeze-dried unit without opening the blister pack.
