Abstract
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.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
