Embodiment Construction

[0085] figure 1 with figure 2 An exemplary inhaler article 100 is illustrated. figure 2 Yes figure 1 A schematic cross-sectional view of an illustrative inhaler article along the longitudinal axis. The inhaler article 100 contains along the longitudinal axis L A The main body 110 extending from the mouthpiece end 112 to the distal end 114 and the capsule cavity 116 defined in the main body 110. The mouthpiece air passage 111 extends from the capsule cavity 116 to the mouthpiece end 112. The end cap 120 is disposed in the distal end 112 and extends to the capsule cavity 116. The end cap 120 extends the end cap length from the distal end 124 of the end cap to the inner end 122 of the end cap. The end cap 120 includes an air channel 113 extending from the distal end 124 of the end cap to the inner end 122 of the end cap. The air channel 113 is not aligned with the longitudinal axis L A parallel.

Abstract

An inhaler article includes a body extending along a longitudinal axis from a mouthpiece end to a distal end and a capsule cavity defined within the body. The capsule cavity has a length extending along the longitudinal axis. A mouthpiece air channel extends from the capsule cavity to the mouthpiece end. An end cap is disposed within the distal end and extends to the capsule cavity. The end cap includes an air channel extending from the end cap distal end to the end cap inner end. A capsule is disposed within the capsule cavity and has a capsule length. The capsule length is in a range from about 25% to about 99% of the cavity length, or about 50% to about 95% of the cavity length, or about 70% to about 90% of the cavity length, or from about 75% to about 85% of the cavity length, or about80% of the cavity length.

Description

Technical field [0001] The present disclosure relates to an inhaler article, which includes an air inlet passage that extends through an end cover to a capsule cavity of a capsule sized therein. Background technique [0002] Dry powder inhalers are not always fully suitable for delivering dry powder particles to the lungs at an inhalation rate or airflow rate within the inhalation rate or airflow rate of conventional smoking. The operation of dry powder inhalers may be complicated or may involve moving parts. Dry powder inhalers generally strive to provide a whole dose of dry powder in a single breath. [0003] There will be a need to provide a nicotine powder inhaler that provides nicotine particles to the lungs at an inhalation rate or airflow rate within the inhalation rate or airflow rate of conventional smoking. There will also be a need to provide an inhaler for delivering nicotine powder in an inhaler product in a form similar to conventional cigarettes. There will also b...
