ABSTRACT:
A foil-backed blister sheet is sandwiched between upper and lower sheets formed by folding a single die-cut card having a heat-sealable adhesive coating on one side. Blisters project through holes in the upper sheet, and the blister contents are removed by pushing them through the foil backing and through holes in the lower sheet. The lower sheet is smaller than the upper one, and the upper and lower sheets are connected together by narrow hinge sections so that a margin area coated with heat-sealable adhesive is presented on the underside of the upper sheet. A third card having a tear strip, which must be removed to gain access to the blister contents, is heat-sealed to the upper card at the margin area. The upper surface of the third card is uncoated paperboard, which readily adheres to the margin area when sealing heat is applied.
