The pack assembly comprises at least a blister-type reservoir pack 1 and a reservoir piercing means 4 that is carried by the pack and movable with respect to it. The piercing means is supported by the carry means 7, which is slidable with respect to the pack in direction 13 along means 18. The piercing means may also be rotatable (3, Fig.4), in order to allow selective positioning over a frangible portion 17 of the reservoir to be able to pierce it. The assembly may include a cover 8, which can be adhesive, surrounding at least partially the pack, and the carry means and the piercing means may be optionally connected to the cover instead of to the blister pack itself. The cover may also have non-frangible portions on which the piercing means could rest to avoid accidental piercing, and the assembly may have a sub frame or bangle 16 for attaching to a users arm. Other embodiments show the piercing means carried on a cover (27-29, fig.7) within which a blister pack can slide, and a plurality of blister-packs on an assembly. |
