Finger grip

A finger grip configured for coupling with a syringe comprising a barrel and a flange, said finger grip comprising:

• a base part of the grip defining a first portion of a cavity of the grip for receiving the flange, and
• a collar part of the grip defining a second potion of the cavity of the grip, for receiving an end portion of the barrel adjacent the flange,
• wherein an inner surface of the base part bounding the first portion of the cavity and an inner surface of the collar bounding the second portion of the cavity are formed such as to respectively provide a first set of first point and/or line contacts for engaging with an exterior surface of the flange, and a second set of second point and/or line contacts for engaging with an exterior surface of the barrel, and
• wherein the inner surface of the base part of the grip and the inner surface of the base part of the grip are smooth or at least free of outwardly extending protrusions for contacting portions of the syringe, over zones that least encompass the contacts comprised in the first and the second set of contacts.

A method of manufacturing a finger grip configured for coupling with a syringe comprising a barrel and a flange;

• said method comprising forming a plastic compound using a mould configured to define:
• a base part of the grip defining a first portion of a cavity of the grip for receiving the flange, and
• a collar part of the grip defining a second portion of the cavity of the grip, for receiving an end portion of the barrel adjacent the flange,
• wherein the mould is configured such that an inner surface of the base part bounding the first portion of the cavity and an inner surface of the collar bounding the second portion of the cavity are formed such as to respectively provide a first set of first point and/or line contacts for engaging with an exterior surface of the flange, and a second set of second point and/or line contacts for engaging with an exterior surface of the barrel, and
• wherein the mould is configured such that the inner surface of the base part of the grip and the inner surface of the base part of the grip are smooth or at least free of outwardly extending protrusions for contacting portions of the syringe, over zones that least encompass the contacts comprised in the first and the second set of contacts.

A method of manufacturing a packaged injection device, said method comprising:

• a) providing a syringe comprising a barrel and a flange;
• b) filling the syringe with a medicament;
• c) providing the finger grip comprising:
• a base part defining a first portion of a cavity of the grip for receiving the flange, and a collar part defining a second potion of the cavity of the grip, for receiving an end portion of the barrel adjacent the flange, wherein an inner surface of the base part bounding the first portion of the cavity and an inner surface of the collar bounding the second portion of the cavity are formed such as to respectively provide a first set of first point and/or line contacts for engaging with an exterior surface of the flange, and a second set of second point and/or line contacts for engaging with an exterior surface of the barrel, and wherein the inner surface of the base part of the grip and the inner surface of the base part of the grip are smooth or at least free of outwardly extending protrusions for contacting portions of the syringe, over zones that least encompass the contacts comprised in the first and the second set of contacts;
• d) coupling the finger grip to the syringe forming an injection device comprising at least the syringe and the finger grip coupled with the syringe;
• e) sterilizing an exterior of the injection device by a process comprising an exposure to a gaseous sterilizing agent;
• f) placing the injection device in a package;
• and
• g) sealing the package,
• wherein the sterilizing is performed after the filling and the coupling.
