Abstract
The present disclosure relates to an audible and/or tactile indicator for use with a drug delivery device including a resilient force member configured to reside in two or more states having two or more different conformations, wherein in a relaxed state, the resilient force member is relaxed in a first conformation, wherein in a biased state, the resilient force member is biased to store energy in a second conformation different to the first conformation, wherein the resilient force member releases stored energy to generate an audible signal when changing from the biased state into the relaxed state due to a transition from the second conformation to the first conformation, wherein the resilient force member is bent by a certain angle about a longitudinal axis forming a longitudinal round fold with two adjacent angled wing-shaped sections.
