Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
134 words
A blister card for child-proof packaging of medicaments in discrete capsule, lozenge, or pill form, comprising a nonrupturable transparent plastic strip having a plurality of blister-like protrusions therein outward from one face and leaving a corresponding plurality of hollows and openings thereinto at the opposite face thereof, a rupturable foil strip adherent to the latter face of the plastic strip and sealing the openings therein, a supporting card portion including a first paper layer juxtaposed to the first face of the plastic strip and having one or more openings therein to accommodate the protrusions and including a second paper layer overlying the foil strip and the first paper layer and adherent thereto, the second paper layer having perforated a like plurality of individual access tabs in the parts thereof opposite the corresponding hollow openings.
Claim 2
Dependent Claim
134 words
A blister card for child-proof packaging of medicaments in discrete capsule, lozenge, or pill form, comprising a nonrupturable transparent plastic strip having a plurality of blister-like protrusions therein outward from one face and leaving a corresponding plurality of hollows and openings thereinto at the opposite face thereof, a rupturable foil strip adherent to the latter face of the plastic strip and sealing the openings therein, a supporting card portion including a first paper layer juxtaposed to the first face of the plastic strip and having one or more openings therein to accommodate the protrusions and including a second paper layer overlying the foil strip and the first paper layer and adherent thereto, the second paper layer having perforated a like plurality of individual access tabs in the parts thereof opposite the corresponding hollow openings.
Claim 3
Dependent Claim
33 words
Blister card according to claim 1, wherein the perforation of the adherent paper layers includes transverse edge-to-edge perforation enabling the card to be folded flap-like to cover the blister-like protrusions and their contents.
Claim 4
Dependent Claim
38 words
Blister card according to claim 2, wherein the perforated access tabs of the second paper layer are rectangular in outline, having two opposite edges perforated, one intervening edge slitted, and the other intervening edge neither perforated nor slitted.
Claim 5
Dependent Claim
75 words
In a blister card the combination of a first strip having a plurality of blister-like protrusions therein outward from one face, and leaving corresponding hollows and openings thereinto at the opposite face thereof, a relatively rupturable second strip adherent to the latter face of the first strip and sealing the openings therein, a supporting card therefor overlying the second strip over the openings and having an openable integrally formed individual access tab opposite each opening.
Claim 6
Dependent Claim
75 words
In a blister card the combination of a first strip having a plurality of blister-like protrusions therein outward from one face, and leaving corresponding hollows and openings thereinto at the opposite face thereof, a relatively rupturable second strip adherent to the latter face of the first strip and sealing the openings therein, a supporting card therefor overlying the second strip over the openings and having an openable integrally formed individual access tab opposite each opening.
Claim 7
Dependent Claim
20 words
Blister card according to claim 4, wherein each of the access tabs is outlined at least in part by perforations.
Claim 8

Blister card according to claim 5, wherein each of the access tabs is outlined in part by a slit of length approximating the width of a fingernAil.
Claim 9
Dependent Claim
55 words
Packaging blank useful in formation of a blister card or the like and comprising a foldable sheet having openings therein spaced to accomodate blister-like protrusions of another sheet and having also therein integral individual access tabs similarly spaced, whereby folding of the sheet therebetween permits juxtaposition of the respective access tabs to the respective openings.
Claim 10
Dependent Claim
55 words
Packaging blank useful in formation of a blister card or the like and comprising a foldable sheet having openings therein spaced to accomodate blister-like protrusions of another sheet and having also therein integral individual access tabs similarly spaced, whereby folding of the sheet therebetween permits juxtaposition of the respective access tabs to the respective openings.
Claim 11
Dependent Claim
22 words
Packaging blank according to claim 7, including an adhesive coating on the face thereof that is folded against itself in such juxtaposition.
Claim 12

39 words
Packaging blank according to claim 9, wherein each access tab also is outlined in part by a slit of length approximating the width of a fingernail and joining the pair of perforated lines at an end thereof its end.
Claim 14
Dependent Claim
110 words
In a blister card having a plurality of non-rupturable blister-like protrusions therein outward from one face, leaving corresponding hollows and openings thereinto at the opposite face, the openings being covered by a layer of relatively rupturable material adherent to the face therof bounding the openings, the improvement comprising a sheet overlying the rupturable layer and non-adherent to the rupturable layer portions opposite the openings and otherwise adherent to the contiguous portions of the card, the portions of the overlying sheet opposite the blister openings having respective access tabs, each tab being delineated from one another and from the edges of the sheet by a circumscribing pattern of weakness lines therein.
Claim 15
Dependent Claim
110 words
In a blister card having a plurality of non-rupturable blister-like protrusions therein outward from one face, leaving corresponding hollows and openings thereinto at the opposite face, the openings being covered by a layer of relatively rupturable material adherent to the face therof bounding the openings, the improvement comprising a sheet overlying the rupturable layer and non-adherent to the rupturable layer portions opposite the openings and otherwise adherent to the contiguous portions of the card, the portions of the overlying sheet opposite the blister openings having respective access tabs, each tab being delineated from one another and from the edges of the sheet by a circumscribing pattern of weakness lines therein.
Claim 16
Dependent Claim
20 words
Blister card according to claim 11, wherein the weakness lines outline all but a minor peripheral extent of each tab.
Claim 17
Dependent Claim
35 words
Blister card according to claim 11 including at least two rows and two columns of access tabs, one for each opening; the portions of the sheet between each two adjacent tabs being smooth and continuous.
