Abstract
A quick-open blister package comprises a base member and a blistered containment member peripherally secured to the base member. The base member is frangible substantially along a plane contained therewithin, and first and second series of score lines extending at least in part about the periphery of the blister are cut into the base member substantially to the depth of the plane of frangibility. The blister is secured to the base member within that area thereof which is defined by the series of score lines. A considerable area of the base member can extend laterally of the blister for front printing.
Claims36
A quick-open blister package comprising a base member having at least one layer, a blistered containment member peripherally secured to said base member, the material of said base member layer being internally frangible in directions parallel to sides of said layer, a series of inner score lines in said base member and extending at least partially about said blistered member and closely adjacent an outer periphery of a pocket thereof, a series of outer score lines in said base member spaced outwardly of said inner series and extending closely and at least partially about the blistered member outer periphery, said inner score lines and said outer score lines excepting any portion of said outer score lines at an edge of said base member layer being cut into a nearer side of said base member layer but terminating short of a far side of said base member layer, said blistered member being secured to said base member within that area thereof between said series of score lines, a substantial area of said base member extending laterally of said blistered member in at least one direction thereof for front printing and the like, said score lines essentially delineating a relatively narrow band of securance area on said base member and at least partially surrounding said blistered member pocket, at least the major proportions of said inner and said outer score lines respectively coextending about said blistered member for this purpose, and means for securing said blistered member to said base member at said securance area band, whereby on opening said package said blistered member and said securance area band can be displaced from said base member by tearing taking place entirely within said base member layer but only between said score lines.
A quick-open blister package comprising a base member having a frangible layer therewithin, a containment blister peripherally secured to said base member, inner and outer score lines cut in said base member substantially to the depth of said frangible layer, said score lines being spaced from one another and partially surrounding said blister, said blister having a peripheral securance flange with portions thereof juxtaposed to an area of said base member enclosed between said score lines, said juxtaposed flange portions being secured and continuously sealed to said base member but only at said enclosed area, said flange having a remaining portion secured and sealed to said base member outside of said enclosed area to form a "living" hinge upon opening of said package, said hinge and said enclosed area completely surrounding said blister.
