Abstract: An inhaler article (100) includes a body (110) extending along a longitudinal axis (LA) from a mouthpiece end (112) to a distal end (114). A capsule cavity (116) is defined within the body and extends along the longitudinal axis. A mouthpiece air channel (111) extends from the capsule cavity to the mouthpiece end. A boundary element (140) is located between the capsule cavity and the mouthpiece air channel. The boundary element includes at least two concentric rings of apertures (142, 144) fluidly connecting the capsule cavity with the mouthpiece air channel, wherein each of the inner appertures of the inner concentric ring has an open area less than each of the outer apertures of the outer concentric ring of apertures.
