Abstract:
1. A cartridge assembly configured to be connected to a dose setting and delivery mechanism, the cartridge assembly comprising: a cylindrical body for holding a medicament reservoir, where the cylindrical body has a proximal end portion having an outer surface and an inner surface; a fastener on either the outer surface or the inner surface of the proximal end portion, the fastener being configured to attach the cartridge assembly to the dose setting and delivery mechanism; and at least one coding feature that is separate from the fastener, the coding feature being coded to engage a corresponding coding feature on the dose setting and delivery mechanism, thereby allowing the cartridge assembly to operably connect to the dose setting and delivery mechanism, where the coding feature is formed as a stop feature and where the corresponding coding feature is formed as a counter stop feature, the stop feature and the counter stop feature being suitable to make contact thereby blocking travel in the connection process and allowing cartridge assembly to operably connect to the dose setting and delivery mechanism; wherein the proximal outer surface of the cylindrical body is positioned between a shoulder and a proximal axial end and the fastener is located on the proximal outer surface and where the coding feature of the cartridge assembly is a pin on the proximal outer surface, where the pin abuts, is in contact with, and extends proximally from a proximal facing surface of the shoulder that protects the pin from damage during cartridge assembly.
