Mouthpiece with Nested Tubular Sections for Aerosol Seal

The mouthpiece is divided into two separate tubular sections: an inner tubular section and an outer tubular section. These segments are positioned concentrically with respect to one another, creating a tapered slot between them. This segmentation allows the aerosol-generating article to be inserted into the slot, providing a secure mechanical interlock that prevents aerosol loss and pressure drops while maintaining structural simplicity.

The inner tubular section is nested within the outer tubular section, forming a concentric arrangement. The tapered slot is created by the difference in diameters between these nested sections. This nesting configuration provides a firm fit for the aerosol-generating article while keeping the overall mouthpiece structure compact and simple.

The tapered slot configuration creates a dynamic connection mechanism. During insertion, the aerosol-generating article is pushed into the tapered slot which gradually narrows, creating a firm mechanical interlock. During removal, the same tapered geometry allows easy extraction by applying force along the insertion axis. This dynamic engagement provides sealability while maintaining ease of operation.

The connection mechanism operates primarily along the longitudinal axis (insertion and removal direction) rather than requiring complex multi-directional fastening. The tapered slot geometry converts radial pressure during insertion into axial retention force, allowing secure attachment through a single-dimensional motion while maintaining ease of detachment through the same motion in reverse.
