Claim 11

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 access tab opposite each opening, and a peelable backing overlying at least the part of the card containing the access tabs without extending to any edge of the card.

Claim 12

Blister card according to claim 8, wherein the card has a tab perforated from one or more edges to and underlying an edge portion of the backing to facilitate initiating peeling removal thereof.

Claim 13

Blister card according to claim 8, wherein each of the access tabs is outlined at least in part by perforations.

Claim 14

In a package having discrete article enclosures, such as a blister card for medicaments or the like in capsule, lozenge, or pill form, the improvement comprising a first, non-rupturable strip haviNg a blister-like protrusion formed therein outward from one face and leaving a corresponding hollow and an opening thereinto at the opposite face thereof, a rupturable second strip adherent to the latter face of the first and sealing the opening, a supporting card including a layer of material secured at one face to the hollowed face of the first strip and having an openable access tab in the part thereof overlying the corresponding hollow opening, and a non-rupturable backing strip overlying the access tab and adherent to part of the second strip and peelable therefrom.

Claim 15

In a package having discrete article enclosures, such as a blister card for medicaments or the like in capsule, lozenge, or pill form, the improvement comprising a first, non-rupturable strip haviNg a blister-like protrusion formed therein outward from one face and leaving a corresponding hollow and an opening thereinto at the opposite face thereof, a rupturable second strip adherent to the latter face of the first and sealing the opening, a supporting card including a layer of material secured at one face to the hollowed face of the first strip and having an openable access tab in the part thereof overlying the corresponding hollow opening, and a non-rupturable backing strip overlying the access tab and adherent to part of the second strip and peelable therefrom.

Claim 16

Package according to claim 11, wherein the backing strip is transparent.

Claim 17

Package according to claim 12, wherein the access tab is visible through the backing strip and is at least partly outlined by perforation of the second layer and by a slit therein to facilitate initiation of opening of the access tab along the perforation.

Claim 18

Package according to claim 11, wherein the supporting material has a line of weakness from an edge thereof underlying a part of the peelable backing strip to facilitate separation of the supporting material therealong preparatory to initiation of peeling thereof.

Claim 19

Package according to claim 14, wherein that edge of the supporting material extends beyond the adjacent edge of the backing strip and thereby exposes an end portion of the line of weakness in the supporting material, thereby further facilitating initiation of peeling.

Claim 20

In a blister card having a plurality of blister-like protrusions therein outward from one face, and leaving corresponding hollows and openings thereinto at the opposite face thereof, relatively rupturable material overlying and sealing the openings therein, supporting material therefor overlying the rupturable material and the underlying openings and having an openable access tab overlying each opening, and a peelable non-rupturable backing overlying at least the part of the card containing the access tabs.

Claim 21

In a blister card having a plurality of blister-like protrusions therein outward from one face, and leaving corresponding hollows and openings thereinto at the opposite face thereof, relatively rupturable material overlying and sealing the openings therein, supporting material therefor overlying the rupturable material and the underlying openings and having an openable access tab overlying each opening, and a peelable non-rupturable backing overlying at least the part of the card containing the access tabs.
