a sufficient collapsing force on the blister 38 to rupture the foil seal under the blister and cause the associated tablet referenced 40 to be expelled through the opening 10 it will be appreciated that since the spindle 26 moves through an arc movement of the lid from the position shown in fig3 and 4 into the position shown in fig5 and 6 will cause a small predominantly vertical movement of the spindle 26 and so will not result in the rod 28 and cross piece 30 pushing the blister pack further forward by any substantial distance the tablet 40 released from the blister 38 falls through the opening 10 into the channel 14 if the lid 24 is then moved back towards its open position this causes the cross piece 38 to ride up over the next pair of blisters 42 and 44 and then engage behind the rear of that pair as shown in fig9 and 10 as this happens rearward movement of the pack is prevented by the pawls 100 and 102 this corresponds to the starting position shown in fig1 and 2 so that movement of the lid 24 back towards the closed position will cause the tablet in the blister 44 to be moved into registry with the opening 10 and then to be expelled into the channel 14 by the abutment 32 tablets such as tablet 40 released into the channel 14 can be retrieved simply by tilting the tray backwards so that the tablet falls through the rear opening 16 to rest against the rear wall 18 from which position the tablet may be picked.
