Abstract
A dose counter includes a housing having an indicator member rotatably mounted in the housing. A drive gear is associated with the indicator member. The drive gear and a flexible support member include interfacing indexing features, with at least a portion of the support member being moveable toward and away from the drive gear. In another aspect, a movement limiter is operably engaged with the indicator member to prevent any rotation of the indicator member in response to actuations occurring between a predetermined number of actuations greater than one. In another aspect, a drive member includes a pawl portion and a biasing portion. The biasing portion is engageable with indicator member and biases the pawl outwardly relative to the indicator member along the axial direction as the drive member is moved from a preassembled position to an assembled position. Medicament devices including containers of medicament, together with methods of use and assembly, are also provided.
