Inhaler system with single plane piercing element

An inhaler system, comprising:

• a housing defining a housing cavity;
• a sleeve extending along a sleeve longitudinal axis and positioned within the housing cavity, wherein the sleeve is movable within the housing cavity between a first position and a second position, wherein the sleeve extends from an open end to a closed end and defines a cylindrical lumen for receiving an inhaler article, the open end of the sleeve is aligned with an opening in the housing for receiving the inhaler article;
• a capsule contained within the inhaler article and received within the sleeve, the capsule having a capsule longitudinal axis;
• and
• a piercing element comprising only a single shaft extending from a fixed end to a tip along a piercing element longitudinal axis, the piercing element longitudinal axis being parallel with the sleeve longitudinal axis, the piercing element having a piercing element diameter in a range from 0.5 to 0.9 mm, and the single piercing element tip having only a single cutting plane and defining a cutting plane angle between the longitudinal axis of the piercing element and the single cutting plane, the cutting plane angle being in a range from about 25 degrees and about 35 degrees, wherein the piercing element longitudinal axis is offset from the sleeve longitudinal axis;
• wherein only a single aperture is formed in the capsule when the sleeve is moved from the first position to the second position.
