AU2011244232B2 — Cartridge holder and alignment interface

USPTO Abstract

A system for a drug delivery device comprising a reservoir holder (380) configured to hold a reservoir (20), and an alignment interface (350) comprising a main body (352) configured to be coupled to the reservoir (20). A first alignment feature (372) is provided on the main body (352). The first alignment feature (372) cooperates with a corresponding alignment feature provided by the reservoir holder (380) such that when the reservoir (20) is inserted into the holder (380), the first alignment feature (372) cooperates with the corresponding alignment feature provided by the holder (380) so as to rotate the alignment interface (350) and thereby align the alignment interface (350) within the holder (380). Thus, the reservoir (20) may be aligned within the reservoir holder (380). The first alignment feature (372) may comprise at least one protrusion provided on the main body (352) of the interface (50). The system further comprises one or more coding features (374, 376).
