Dose button for a drug delivery device and method for manufacturing a dose button

A set of at least two drug delivery devices each comprising:

• a metal dose button manufactured by means of a cutting-off process and including a characteristic surface having a tactile feature that forms a pattern, the pattern of the tactile feature being indicative of a drug to be delivered by the respective drug delivery device,
• wherein the tactile feature of each dose button is formed by a cutting-off process such that one or more cutting marks laterally surround the tactile feature on the characteristic surface of the dose button;
• a housing comprising a housing body and a cartridge holder releasably attached to the housing body, wherein the cartridge holder is adapted to hold a cartridge containing the drug to be delivered by the respective drug delivery device;
• and
• a removable cap adapted to cover the cartridge holder,
• wherein every drug delivery device in the set is distinguishable from every other by the characteristic surface structure of its dose button,
• wherein each respective drug delivery device is configured for delivery of a different drug,
• wherein, for each drug delivery device, the housing body, the cap, and one or both of the cartridge holder and the cartridge each comprise a respective tactile feature, the respective tactile feature being substantially equivalent or identical to the tactile feature of the dose button of the respective device, and
• wherein the tactile feature is different for each of the at least two drug delivery devices.

A drug delivery device comprising:

• exactly one dose button;
• a housing comprising a housing body and a cartridge holder releasably attached to the housing body, wherein the cartridge holder is adapted to hold a cartridge containing a drug;
• and
• a removable cap adapted to cover the cartridge holder,
• wherein a surface of the dose button has a specific structure forming a tactile marking that is indicative of the drug contained within the cartridge held by the cartridge holder of the drug delivery device,
• wherein the surface of the dose button further comprises one or more cutting marks from a cutting-off process,
• wherein the tactile marking of each dose button is formed by the cutting-off process such that the one or more cutting marks laterally surround the tactile feature on the surface of the dose button, and
• wherein the housing body, the cap, and one or both of the cartridge holder and the cartridge each comprise a respective tactile feature substantially equivalent or identical to the tactile feature of the dose button.
