    摘要: A method for filling a plurality of microdepressions in a major surface of a web with finely divided powder in which the web is fed continuously to and through a powder filling stage including a driven roller. A method of manufacturing an elongate carrier with microdepressions containing finely divided powder comprising steps filling a plurality of microdepressions in a major surface of a web as described, removing from upper surface of the web excess powder not filled within the microdepressions and remaining on areas of the surface between the depressions, and optionally slitting and/or cutting the web in width and/or length.

    摘要: The disclosure describes powder inhalers and dry powder inhaler storage cassettes that include a compartment housing an elongate carrier preloaded with a plurality of doses of finely divided powder comprising a biologically active substance. The compartment is configured such that the preloaded doses are sealed within the compartment and such that the carrier may be advanced from the compartment to the chamber through an exit provided with a moisture barrier sealing system. The moisture barrier sealing system is configured and arranged such that it is relaxable during advancement of the carrier. The sealing system is in sealing configuration prior to an advancement of the carrier, is relaxed upon an advancement of the carrier and is returned to its sealing configuration at the latest after release of the powder associated with the area of the carrier.
