Cartridge unit coupler

Abstract

Some embodiments relate to a cartridge for use with an inhaler, the cartridge comprising: a plurality of source material units and a unit coupler configured for selectively interlocking to each of the source material units so that when the cartridge is operably attached to the inhaler, manipulation of the unit coupler moves the interlocked source material unit away from or back into the cartridge; the unit coupler and each of the source material units being formed with an interlocking geometry in which a protrusion of one fits within a respective recess of the other.

Dependencies are inferred from the claim text.
