Patent number: 5569484Abstract: A process is provided for the production of a flat administration form with a dosable portion of drugs or of a flat-shaped device for the dosable release of volatile substances, such as aromatic substances, to the ambient air by using high-volatile or thermolabile dosing media in liquid or semisolid state as the ingredients of the administration form or of the device by means of printing processes. A free-flowing preparation of the ingredients is knife-coated in a measured amount into at least one volumetrically defined cavity of a flat printing block. A substrate to be charged with the ingredients or dosing media, respectively, is gradually led as web-shaped material under web tension over the cavity of the printing block and pressed into the filled cavity by means of a mechanical pressure device whereby the substrate takes up the ingredient from the printing block in a dosed amount.Type: GrantFiled: May 19, 1995Date of Patent: October 29, 1996Assignee: LTS Lohmann Therapie-Systeme GmbH & Co.
