Abstract

An inhaler article includes a tubular housing defining a holder body extending along a longitudinal axis from a mouthpiece end to a consumable receiving end. The holder body includes an inner tube extending along the longitudinal axis and within the tubular housing from a tube intake end to a tube exhaust end. The tube intake end is proximate the consumable receiving end. The inner tube defines anair flow lumen with two or more air flow apertures extending through a wall of the inner tube. An air blocking feature is positioned in the air flow lumen and between two of the air flow apertures. Avibration inducing element disposed on the inner tube proximate to the tube exhaust end or the tube intake end, the vibration inducing element comprises an aperture through the wall of the inner tubeand having a tapered or angled downstream aperture edge.

Description

Technical field [0001] The present disclosure relates to an inhaler article that includes an air-blocking element for delivering particles, such as particles including nicotine, to a user. 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 an inhaler article that provides particles including nicotine to the lungs at an inhalation rate or airflow rate that is within the inhalation rate or airflow rate of conventional smoking. There will also be a need to provide inhaler articles that deliver nicotine-containing particles in a form similar to conventional cigarettes. There will also ...
