Container holder assembly
Container holder assembly for use in a medicament delivery device, comprising a tubular body elongated in an axial direction, said tubular body having a proximal end and an opposite distal end, and a retaining member releasably arranged to said tubular body for securing an elongated container placed inside the tubular body, wherein said retaining member comprises a resilient structure capable of exerting an axial force on said container in said tubular body for holding the container in a fixed position inside the tubular body and thereby avoiding displacement or breakage of the container and wherein a distal end of said container protrudes from a distal end of said tubular body.
1. A container holder assembly, comprising: a tubular body comprising a proximal end and a distal end;
a flange located on an outer circumferential surface of the tubular body; and
a retaining member releasably attached to the outer circumferential surface of the tubular body at the distal end of the tubular body for securing a container placed inside the tubular body,
wherein the retaining member comprises a resilient structure containing a resilient washer configured to exert an axial force on the container in the tubular body, and
wherein a proximal surface of the flange directly engages a distal surface of the resilient structure.
2. The container holder assembly of claim 1 , wherein the retaining member comprises the resilient structure configured to exert the axial force on the container in the tubular body, thereby avoiding breakage or displacement of the container.
3. The container holder assembly of claim 1 , wherein the retaining member further comprises an annular housing configured to accommodate the resilient structure.
4. The container holder assembly of claim 3 , wherein the annular housing comprises an axially aligned annular housing.
5. The container holder assembly of claim 4 , wherein the annular housing comprises a multi-part annular housing.
6. The container holder assembly of claim 5 , wherein at least one part of the multi-part annular housing comprises an attachment configured to allow the retaining member to be connected to a medicament delivery device.
7. The container holder assembly of claim 6 , wherein the attachment comprises a bayonet connection.
8. The container holder assembly of claim 1 , wherein the retaining member is configured to accommodate the tubular body such that a distal surface of an annular spacer abuts the proximal surface of the flange of the tubular body.
9. The container holder assembly of claim 1 , wherein the flange comprises a circumferential flange located on the outer circumferential surface of the tubular body.
10. The container holder assembly of claim 9 , wherein the circumferential flange located on the outer circumferential surface of the tubular body and comprising a proximal surface and a distal surface.
11. The container holder assembly of claim 1 , wherein the resilient structure is configured to exert the axial force on the container in the tubular body for holding the container in a fixed position.
12. The container holder assembly of claim 11 , wherein the resilient structure is configured to exert the axial force on the container in the tubular body for holding the container in the fixed position inside the tubular body.
13. The container holder assembly of claim 1 , wherein the container comprises a shoulder portion abutting a proximal inner annular ledge of the tubular body.
14. The container holder assembly of claim 1 , wherein the retaining member is configured for releasable attachment to an outer surface of a proximal end of a medicament delivery device.
15. The container holder assembly of claim 14 , wherein the retaining member is configured for releasable attachment to the proximal end of the medicament delivery device, such that the distal end of the container is resiliently pressed against a stop of the medicament delivery device.
16. A medicament delivery device, comprising the container holder assembly according to claim 1 .
17. The medicament delivery device of claim 16 , wherein the container comprises a shoulder portion abutting a proximal inner annular ledge of the tubular body.
18. The medicament delivery device of claim 16 , wherein the retaining member is configured for releasable attachment to a proximal end of the medicament delivery device.
19. The medicament delivery device of claim 18 , wherein the retaining member is configured for releasable attachment to the proximal end of the medicament delivery device such that the distal end of the container is resiliently pressed against a stop of the medicament delivery device.
20. The medicament delivery device of claim 16 , wherein the resilient structure comprises an annular spacer.
