Claims12
1-16. (canceled)
A pack assembly comprising two packs of medicinal tablets joined together, each pack being provided with an external cover piece, the two packs being joined such that the assembly has a stowed configuration in which the medicinal tablets cannot be expelled and an opened configuration in which the medicinal tablets can be expelled, the external cover pieces being in a face-to-face relation when the assembly is in its stowed configuration;
- each said pack comprising:
- a base wall which defines a plurality of locations for the tablets, wherein at each said location there is a displaceable pocket which is substantially dome-shaped and integral with the base wall and which constitutes a recess for a tablet,
- an internal cover piece of a rupturable material, and
- a tablet between the displaceable pocket and the internal cover piece,
- wherein the base wall is of a sufficiently rigid construction as to be resistant to permanent deformation and is elastic such that it can be reversibly flexed;
- wherein a junction between the pocket and the base wall acts as a hinge such that the pockets are bistable and have a concave position in which the pocket accommodates a tablet and a convex position in which the tablet is forced from the pocket;
- and
- wherein each pack is formed by injection moulding.
26 A method according to claim 25, wherein the pack is moulded so 25, that the pockets are formed in the inverted state and are then forced into the non-inverted state after moulding.
A method according to claim 26, wherein the pockets are forced into the non-inverted state by means of mechanical or hydraulic force.
