Adaptor for Connecting a Connector to a Distal Tip of a Medical Container, Tip Cap Assembly and Drug Delivery Device for Engaging Said Adaptor, and Method for Manufacturing Said Adaptor

An adaptor for connecting a connector comprising two outer wings to a distal tip of a medical container, the adaptor-) comprising:

• a tubular lateral wall extending around a longitudinal axis of the adapter, the tubular lateral wall defining an opened proximal end for receiving the distal tip and an opposite opened distal end for receiving the connector,
• an inner ring located at the proximal end for securing the adaptor to the distal tip of the medical container,
• two inner bulges inwardly protruding from the tubular lateral wall, the two bulges defining a unique inner cavity for guiding translation of the connector inside the adaptor-along the longitudinal axis of the adapter, a distal end of the inner bulges defining an index opening for orientating the connector with regard to the adaptor in a first angular position in which the connector is allowed to enter the inner cavity, the inner bulges including a first blocking surface for blocking rotation of the connector in a first rotational direction during insertion of the connector in the inner cavity,
• two locking slots located proximally to the inner cavity and distally to the inner ring for allowing the connector in an inserted position to rotate around the longitudinal axis of the adapter, in a second rotational direction opposite said first rotational direction, such that each of the outer wings of the connector engage one of the locking slots, the locking slots including a mechanical stop for stopping rotation of the connector in a second angular position and an abutment surface for preventing the connector from moving back in the distal direction.
