Medicament container holder
The present invention relates to a medicament container holder ( 10 ) comprising a body ( 12 ) adapted to receive a medicament container ( 14 ), the body ( 12 ) comprising proximally directed tongues ( 38 ) at its proximal end, engagement elements ( 42 ) arranged at the proximal end of the tongues ( 38 ), directed inwards, which engagement elements ( 42 ) are arranged to engage a neck portion ( 46 ) of the medicament container ( 14 ); wherein the tongues ( 38 ) deflect radially outwards when engaged by a needle shield ( 16 ) of said medicament container ( 14 ). The invention is characterised in that said tongues ( 38 ) with said engagement elements ( 42 ), engage with said neck portion ( 46 ) of said medicament container ( 14 ) for preventing the medicament container ( 14 ) from moving in a proximal direction relative the medicament container holder ( 10 ), when disengaged with said needle shield, wherein said tongues ( 38 ) are in a stressed state when in engagement with said neck portion ( 46 ).
1. A medicament container holder comprising:
a body adapted to receive a medicament container, the body comprising a plurality of tongues at a proximal end of the body; and
a plurality of engagement elements arranged at a proximal end of the plurality of tongues, directed inwards, wherein the plurality of engagement elements are arranged to engage a neck portion of the medicament container;
wherein the plurality of tongues deflect radially outwards from a non-stressed state when engaged by a needle shield of said medicament container,
wherein said plurality of tongues with the plurality of engagement elements, engage with the neck portion of the medicament container for preventing the medicament container holder from moving in a proximal direction relative the medicament container holder, when disengaged from the needle shield,
wherein the plurality of tongues are in a stressed state when in engagement with the neck portion, and
wherein an entire length of the plurality of tongues are designed with an inwardly tapering as seen in the proximal direction in a non-engaged state.
2. A medicament container holder according to claim 1 ,
wherein the plurality of tongues are formed by longitudinally extending slits in a proximal area of the medicament container holder.
3. A medicament container holder according to claim 2 ,
wherein the longitudinally extending slits terminate in a cut-out for enhancing bending.
4. A medicament container holder according to claim 3 ,
wherein the cut-out comprises a circular cut out.
5. A medicament container holder according to claim 1 ,
wherein the body defines a first inner diameter, and
the plurality of inwardly tapering tongues define a second inner diameter,
wherein the second inner diameter is smaller than the first inner diameter.
6. A medicament container holder according to claim 1 ,
wherein the plurality of engagement elements comprise a plurality of radial, inwardly directed protrusions.
7. A medicament container holder according to claim 6 ,
further comprising a central passage that is defined by the plurality of radial, inwardly directed protrusions.
8. A medicament container holder according to claim 6 ,
wherein a radial dimension of the radial, inwardly directed engagement elements is chosen such that the plurality of tongues are prevented from fully flexing back to the non-stressed state when in contact with the neck portion of the medicament container.
9. A medicament container holder according to claim 1 ,
wherein the engagement elements are arranged with distally directed surfaces.
10. A medicament container holder according to claim 9 ,
wherein the distally directed surfaces having inclinations generally corresponding to the neck portion of the medicament container.
11. A medicament container holder according to claim 1 ,
wherein the plurality of engagement elements comprise a ledge.
12. A medicament container holder according to claim 1 , further comprising
a holding element at a distal end thereof,
the holding element arranged to cooperate with a flange of the medicament container for holding a distal end of the medicament container.
13. A medicament container holder according to claim 12 ,
wherein the holding element further comprises at least one support element for supporting a distal end of the medicament container.
14. A medicament container holder according to claim 1 , further comprising
at least one attachment element arranged to attach the medicament container holder to a medicament delivery device.
15. A medicament delivery device comprising a medicament container holder according to claim 1 .
16. A medicament container holder according to claim 1 ,
further comprising an outwardly extending circumferential flange extending from a distal end of the container holder.
17. A medicament container holder according to claim 16 ,
wherein the outwardly extending circumferential flange provides a rotational stop that prevents the medicament holder from rotating.
18. A medicament container holder according to claim 17 ,
wherein the rotational stop is configured to be positioned within a holding element including at least one cut away portion provided in a radially extending flange of the medicament container.
