Product container holder for an injection device and for receiving a product container
View Patent ↗A product container holder for accommodating a product container, wherein the product container holder can be separately handled and can be inserted into an injection device, and includes an engaging member that can be moved transversely to the longitudinal axis of the product container holder and which can block a movement of the product container relative to the product container holder in the distal direction, and a securing structure which can be moved relative to the engaging member from an initial position to a securing position in which it restricts the mobility of the engaging member. In some embodiments, a method of making and a method of using the product container holder is encompassed, as is a container and an injection device with which the holder can be used.
1. A product container holder for accommodating a product container and a needle protecting sleeve on the product container, wherein the product container holder can be separately handled, said product container holder comprising:
a) an engaging member for engaging the product container, said engaging member arranged such that it can be moved transversely relative to the longitudinal axis of the product container holder and such that it can block a movement of the product container relative to the product container holder in the distal direction, wherein the engaging member comprises an inwardly protruding cam; and
b) a securing means which can be moved relative to the engaging member from an initial position into a securing position in which it secures the engagement of the engaging member and product container by restricting the mobility of the engaging member, wherein the securing means is either substantially inflexible or rigid and holds the engaging member in engagement with the product container and wherein the product container holder and the securing means are molded and provided as one piece; wherein
c) the product container holder can be inserted into an automatic injection device and a product in the product container is administered automatically after the automatic injection device is triggered.
2. The product container holder according to claim 1 , wherein the engaging member can be moved flexibly or spring-elastically.
3. The product container holder according to claim 1 , further comprising at least one guiding member which can laterally guide the product container, wherein the at least one guiding member is elastically pliable and wherein the engaging member is arranged on the at least one guiding member.
4. The product container holder according to claim 3 , wherein a number of guiding members are circumferently provided and connected to each other at their proximal ends and to the securing means at their distal ends.
5. The product container holder according to claim 4 , wherein the securing means can block the transverse movement of the engaging member to and away from the longitudinal axis of the product container holder.
6. The product container holder according to claim 1 , wherein the securing means surrounds the engaging member and forms a passage for the engaging member and/or the product container and/or is substantially inflexible.
7. The product container holder according to claim 1 , wherein in the securing position, the securing means is arranged by a connecting means such that it cannot be axially shifted relative to the engaging member, wherein the connecting means is based on a positive fit and/or force fit.
8. The product container holder according to claim 7 , wherein the connecting means, as measured along the longitudinal axis, is attached in the region of the engaging member.
9. The product container holder according to claim 1 , wherein the product container holder exhibits an overall length greater in the initial position of the securing means than in the securing position of the securing means, and wherein the securing means forms the distal end of the product container holder in its initial position.
10. The product container holder according to claim 3 , wherein the securing means is formed in a force fit, positive fit or material fit on the product container holder, on the at least one guiding member, and in its initial position is arranged in relation to the engaging member such that the engaging member can be moved.
11. The product container holder according to claim 1 , wherein the securing means is fastened to the product container holder via at least one stay, wherein the stay serves as a predetermined breaking point and can be broken as the securing means moves into the securing position.
