Abstract: A button for a drug delivery device with a reduced operating loudness includes a plate-like button body forming a touch surface, wherein the plate-like button body is coupled by an axial supporting member to a noise-generating interface of the drug delivery device and movable into a longitudinal direction of the drug delivery device, wherein the plate-like button body includes a material composite with at least one first component consisting of a first material and at least one second component consisting of a second material different from the first material, wherein the at least one first component and the at least one second component are coupled via at least one coupling plane that is at least section wise slanted or perpendicular to the longitudinal direction. Further, the disclosure describes a button assembly for a drug delivery device which is shock resistant.

Abstract: An accessory attachment system includes a channel element arranged to receive one or more repositionable accessories. A pivotally mounted spring-based clasp with a hook element engages a lower lip of the channel element. Restraint cooperating elements such as protrusions or recesses of an accessory are configured to cooperate with laterally spaced accessory motion restraints such as recesses or protrusions of the channel element to inhibit lateral movement and rotation of an accessory body. An accessory including laterally spaced restraint cooperating elements and a pivotally mounted spring-biased clasp, as well as an attachment method, are further provided.
