Title
(EN) INHALER ARTICLE WITH OPEN DISTAL END, AND INHALER SYSTEM
(FR) ARTICLE D'INHALATEUR À EXTRÉMITÉ DISTALE OUVERTE, ET SYSTÈME D'INHALATEUR
Abstract
(EN)
An inhaler article (150) includes a body (151) extending along a longitudinal axis of the inhaler article from a mouthpiece end (154) to a distal end (156), a capsule cavity (155) and a capsule (160) retained within the capsule cavity. The capsule cavity is defined within the body and bounded downstream by a filter element (157) and bounded upstream by a tubular element (153) defining a central passage (152) in fluid communication with the capsule cavity. The central passage forms an air inlet aperture extending along the longitudinal axis of the inhaler article from the distal end of the body towards the capsule cavity, wherein the tubular element has a central passage inner diameter in a range from about 50% to about 90% of an inner diameter of the capsule cavity. The inhaler article is configured to receive a swirling inhalation airflow into the central passage.
(FR)
L’article d'inhalateur (150) comprend un corps (151) s'étendant le long d'un axe longitudinal de l'article d'inhalateur d'une extrémité d'embout buccal (154) à une extrémité distale (156), une cavité de capsule (155) et une capsule (160) retenue à l'intérieur de la cavité de capsule. La cavité de capsule est définie à l'intérieur du corps et délimitée en aval par un élément de filtre (157) et délimitée en amont par un élément tubulaire (153) définissant un passage central (152) en communication fluidique avec la cavité de capsule. Le passage central forme une ouverture d'entrée d'air s'étendant le long de l'axe longitudinal de l'article d'inhalateur de l'extrémité distale du corps vers la cavité de capsule, l'élément tubulaire ayant un diamètre interne de passage central dans une plage allant d'environ 50 % à environ 90 % d'un diamètre interne de la cavité de capsule. L'article d'inhalateur est conçu pour recevoir un flux d'air d'inhalation tourbillonnant dans le passage central.
