Abstract
A blister sheet () has a generally rectangular blister () formed with one pair of longer side walls () having parallel steps () and a second pair of shorter side wall () devoid of steps. The side walls serve to space a front face () of the blister from the plane of a rupturable foil backing sheet () which retains medication doses (nor shown) inside the blister until they are to be taken. The medication doses are ejected from the cavity of the blister () by depressing its front face with finger pressure so that they are forced against the backing sheet () with sufficient force to rupture it. During the application of finger pressure to the front face () it bows downwardly in its central region as indicated by the broken outline. Simultaneously the end walls () tilt inwardly towards one another so that any medication doses lying against them are forced into the central region of the blister from which they can be ejected more easily by the descending front face ().
