ABSTRACT:
A blister pack has a main sheet unitarily formed with an array of pockets each dimensioned to receive a respective object and a frangible foil overlying a front face of the sheet and closing the pockets so that objects in the pockets are hermetically sealed therein by the foil. A pair of guides unitarily formed with the main sheet flank the array of pockets. A protective panel having an array of holes substantially identical to the array of pockets overlies the foil and is displaceable in the guides between a rest position with the holes at least partially offset from the pockets and the panel blocking the pockets and a dispensing position with the holes aligned with the pockets. A spring web unitarily formed with the sheet and with the panel urges the panel into the rest position.
