Abstract
Abstract Blister pack for button batteries (5) having a substrate card (1) of cardboard, on which a two-dimensionally stabilizing main panel (2) and an edge-oriented battery receiving area (4) are bounded by a straight line of weakness (3). On the receiving area (4) there are separating cuts (6) along the line of weakness (3) at right angles from the latter to the substrate card edge, as a result of which individual compartments (7) are formed, which are made pivotal independently of one another about the line of weakness (3).

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
245 words
A blister pack for button batteries, comprising a transparent covering film having a plurality of cups, each cup being sized and shaped so as to receive a button battery; a substrate card having a receiving area bordered on one side by a first peripheral edge of said substrate card and on an opposite side by a line of weakness extending parallel to said first peripheral edge intermediate said first peripheral edge and a second peripheral edge of said substrate card, said second peripheral edge being opposite to said first peripheral edge, said receiving area including a plurality of separating cuts extending between said line of weakness and said first peripheral edge in a direction generally perpendicular thereto so as to form a plurality of individual flaps arranged side-by-side along said receiving area, each flap being pivotable about said line of weakness independently of the other of said flaps and having a free end remote from said line of weakness; and attaching means for attaching said covering film to said substrate card and to said flaps thereof such that each cup of said covering film overlies a corresponding one of said flaps to form a plurality of compartments for button batteries and such that said free ends of said flaps form an extremity of said blister pack to thereby facilitate selective accessing of button batteries contained in said compartments by permitting said flaps to be individually gripped and then independently pivoted about said line of weakness.
Claim 2
Dependent Claim
245 words
A blister pack for button batteries, comprising a transparent covering film having a plurality of cups, each cup being sized and shaped so as to receive a button battery; a substrate card having a receiving area bordered on one side by a first peripheral edge of said substrate card and on an opposite side by a line of weakness extending parallel to said first peripheral edge intermediate said first peripheral edge and a second peripheral edge of said substrate card, said second peripheral edge being opposite to said first peripheral edge, said receiving area including a plurality of separating cuts extending between said line of weakness and said first peripheral edge in a direction generally perpendicular thereto so as to form a plurality of individual flaps arranged side-by-side along said receiving area, each flap being pivotable about said line of weakness independently of the other of said flaps and having a free end remote from said line of weakness; and attaching means for attaching said covering film to said substrate card and to said flaps thereof such that each cup of said covering film overlies a corresponding one of said flaps to form a plurality of compartments for button batteries and such that said free ends of said flaps form an extremity of said blister pack to thereby facilitate selective accessing of button batteries contained in said compartments by permitting said flaps to be individually gripped and then independently pivoted about said line of weakness.
Claim 3
Dependent Claim
28 words
A blister pack according to claim 1, wherein said free end of each of said flaps extends outwardly beyond said covering film to form an exposed gripping zone.
Claim 4
Dependent Claim
83 words
A blister pack according to claim 1 or 2, wherein said covering film extends as a single piece over the entirety of said receiving area, and wherein said attaching means includes an elongated bonding zone between said covering film and said flaps and a plurality of punctiform welding spots, each of said welding spots releasably securing a corresponding one of said flaps to said covering film such that each of said compartments is releasably secured by a corresponding one of said welding spots.
Claim 5
Dependent Claim
30 words
A blister pack according to claim 3, wherein said bonding zone includes a reusable adhesive whereby opened compartments may be resecured thereby functioning as a depository for used button batteries.
Claim 6
Dependent Claim
43 words
A blister pack according to claim 1 or 2, wherein said covering film is divided into a plurality of separable sections, each of said sections overlying a corresponding one of said flaps, whereby said compartments may be individually detached from said blister pack.
Claim 7
Dependent Claim
29 words
A blister pack according to claim 1, wherein each of said compartments includes a sealing zone of oxyen-impermeable adhesive onto which a zinc-air button battery is to be placed.
Claim 8
Dependent Claim
25 words
A blister pack according to claim 6, wherein said oxygen-impermeable adhesive extends over the portion of each of said flaps which underlies said covering film.
Claim 9
Dependent Claim
66 words
A blister pack according to claim 1, wherein said substrate card further includes a plurality of openings extending from a first planar surface proximate to said covering film to a second planar surface remote from said covering film, each of said openings being sized and shaped to receive a button battery, and a supporting sheet adhesively attached to said second planar surface of said substrate card.
Claim 10
Dependent Claim
26 words
A blister pack according to claim 8, wherein said supporting sheet is attached to said second planar surface of said substrate card by an oxygen-impermeable adhesive.
Claim 11
Dependent Claim
15 words
A blister pack according to claim 8, wherein said adhesive is a silicon-based bonding agent.
Claim 12
Dependent Claim
17 words
A blister pack according to claim 8, wherein said supporting sheet is made from an oxygen-impermeable material.
Claim 13
Dependent Claim
41 words
A blister pack according to claim 8, wherein said supporting sheet is divided into a plurality of separable sections, each of said sections overlying a corresponding one of said flaps, whereby said compartments may be individually detached from said blister pack.
