An inhaler (1) including a blister strip (2) is proposed. The unused blister strip is stored in a spiral (16). After use, the blister strip is conveyed into another spiral (17). Both spirals share a common space within the inhaler and may be separated by a loose guiding element (18). The spirals and the guiding element may comprise protrusions (19) to reduce sliding friction. Additionally or alternatively, a lubricant (31) may be used to reduce friction.
