Embodiment Construction

[0108] figure 1 and figure 2 An exemplary inhaler system 100 including an inhaler article 110 is shown. The inhaler article 110 may include a capsule 130 disposed within the inhaler article 110 to make up the inhaler system 100 .

[0109] The inhaler article 110 includes a body 112 extending from a mouthpiece end 113 to a distal end 114 along a central longitudinal axis "A". The mouthpiece end 113 forms the downstream end and the distal end 114 forms the upstream end of the inhaler article 110 . In other words, the mouthpiece end 113 is downstream of the distal end, as indicated by the arrow. A capsule chamber 116 is defined within the body 112 . Distal element 118 is disposed at distal end 114 and extends to capsule cavity 116 .

[0110]The distal element 118 includes an element distal end 120 and an element inner end 122 adjacent the capsule cavity 116 . Distal element 118 includes a solid core portion 124 and at least two helical grooves 126 extending from element di...

Abstract

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 a distal element (118) disposed at the distal end and extending to the capsule cavity. The distal element includes an element distal end (120), an element inner end (122), a solid core portion (124), and at least two grooves (126). The solid core portion extends from the element distal end to the element inner end. The at least two grooves are helical grooves that rotate about the solid core portion along a longitudinal axis from the element distal end to the element inner end. The at least two helical grooves extend along an outer surface (128) of the distal element.

Description

technical field [0001] The present disclosure relates to an inhaler article having a twist-type distal element and a method of making a twist-type distal element. Background technique [0002] Dry powder inhalers may not always be perfectly suited to deliver dry powder particles to the lungs at an inhalation rate or airflow rate that is within conventional smoking modality inhalation rates or airflow rates. Dry powder inhalers can be complicated to operate, or may involve moving parts. Dry powder inhalers generally strive to deliver the entire dose of dry powder in a single breath. [0003] Dry powder inhalers are generally formed from non-biodegradable materials. Additionally, these dry powder inhalers are often formed from materials that may require injection molding or casting, and the assembly of these parts can present bottlenecks in the manufacturing process and be difficult to produce at high speeds. [0004] It would be desirable to provide an inhaler article that...
