An inhaler article (110) includes a body (112) extending along a longitudinal axis (A) from a mouthpiece end (113) to a distal end (114), a capsule cavity (116) defined within the body, and disposed at the distal end distal element (118) at and extending to the capsule cavity. The distal element includes a distal element end (120), an inner element end (122), a solid core portion (124), and at least two grooves (126). The solid core portion extends from the distal end of the element to the inner end of the element. The at least two grooves are helical grooves that rotate about a solid core portion along a longitudinal axis from the distal end of the element to the inner end of the element. The at least two helical grooves extend along the outer surface (128) of the distal element. |
