Abstract:
1. A blister package incorporated into a pharmaceutical treatment card for dispensing a pre-measured dosage of a pharmaceutical composition, the card is characterized as a uniform edge multiple layer laminate assembly comprising proportionally dimensioned first and second sides divided by hinging means, said first and second sides comprising interior and exterior layers, said second side further comprising a blister package affixed between said interior and exterior layers along an edge of the second side opposite the hinging means, said blister package comprising: (a) a blister layer comprising a plurality of raised blister cavities conforming to the shape of a pharmaceutical composition contained therein; (b) a lidding layer attached to the blister layer on a side opposite the blister cavities for containing the pharmaceutical composition within the blister cavities; (c) a peelable backing layer abutting the lidding layer opposite the blister layer; (d) a plurality of adhesive layers between each of the interior and blister layers, blister and lidding layers, peelable backing and exterior layers, said adhesive layers being suitable for affixing the layers together, except that substantially no adhesive layer is between the lidding and backing layers; (e) a plurality of first perforation lines being about perpendicular to the hinging means and parallel to one another, said lines extending through the blister, lidding, peelable and adhesive layers, and between each of the blister cavities for separating the individual blister cavities to form quadrants; (f) a plurality of notch cavities located in the blister layer, each of the notch cavities being adjacent to and associated with each of the blister cavities and located along the first perforation lines, said notch cavities being of equal or less volume to said blister cavities volume, so that a void exists between the notch cavities and the lidding layer at each of the notch cavities; (g) a continuous second perforation line extending through the blister, lidding, peelable backing, adhesive, interior and exterior layers, and along the uniform edge of the second side opposite the hinging means to form a barrier strip so that a portion of said barrier strip extends through each of the notch cavities, wherein the second perforation line is about perpendicular to and intersects the first perforation line at a notch cavities; (h) a tab consisting essentially of an area proximal to the notch cavities wherein portions of the lidding layer and backing layers are affixed together by an adhesive; (i) a barrier strip consisting essentially of a laminate assembly of the interior, exterior, blister, lidding and backing layers adhered together, said barrier strip being an area of the second side of the card parallel and opposite the hinging means, said barrier strip and second side being divided by the second perforation line; and (j) an area of the interior and exterior layers within the second side of the card proximal to the blister package wherein said layers have been removed to expose the blister cavities and notch cavities, and first and second perforated lines, wherein each of the blister cavity being opened by a method of tearing away a portion of the barrier strip to expose a portion of each of the notch cavities, clasping the tab in the region of each of the notch cavities, peeling said backing layer away from the lidding layer and towards the composition to expose the lidding layer, and pushing each of the blister towards the composition to cause the composition to rupture the lidding layer thereby exposing the composition.
