Title
(EN) UNIT DOSE DRY POWDER INHALER
(FR) INHALATEUR DE POUDRE SÈCHE MONODOSE
Abstract
(EN) The invention provides a unit dose dispenser in the form of a blister containing a dry powder for inhalation. The blister comprises a base material in which a cavity is formed comprising a bowl that contains the powder and a channel that opens into the bowl. The channel contains a tube that has separate sections that provide an air outlet and an air inlet. The air outlet is further from the bowl than the air inlet. The upper side of the tube is flat and level with the top of the channel. A lid material, such as a foil or foil laminate, seals the cavity. The blister has a detachable portion which, when removed, exposes the air inlet and the air outlet. A process for making the unit dose dispensers is also provided, which is based on the conventional process for manufacturing blister strips for dry powder inhalers.
(FR) L'invention concerne un distributeur de dose unitaire sous la forme d'un blister contenant une poudre sèche pour inhalation. Le blister comprend un matériau de base dans lequel est formée une cavité, comprenant un bol qui contient la poudre et un canal qui s'ouvre dans le bol. Le canal contient un tube présentant des sections séparées qui fournissent une sortie d'air et une entrée d'air. La sortie d'air est plus éloignée du bol que l'entrée d'air. Le côté supérieur du tube est plat et est au niveau de la partie supérieure du canal. Un matériau formant couvercle, tel qu'une feuille ou un stratifié de feuille, scelle la cavité. Le blister comporte une partie détachable qui, lorsqu'elle est retirée, expose l'entrée d'air et la sortie d'air. L'invention concerne également un procédé de fabrication des distributeurs de doses unitaires, qui est basé sur le procédé classique de fabrication de bandes alvéolées pour inhalateurs de poudre sèche.
