Adhesive device

Claim 2

An adhesive sheet device for mounting flat objects to be viewed, comprising a backing sheet having a face and at least one edge, a flexible cover sheet of transparent material covering a portion of said backing sheet, securing means at the edge of said backing means for securing the cover sheet to the face of said bacKing sheet along the edge, pressure sensitive adhesive means on at least a portion of the surface of said backing sheet for removably bonding said cover sheet to said backing sheet, said adhesive means including a pressure sensitive adhesive extending continuously along the direction transverse to said edge, said adhesive means being spaced from said securing means to form an adhesive free strip-shaped zone extending parallel to the edge and spaced from the edge, said cover sheet being substantially unsecured and unbonded to said backing means along the zone, the adhesive free zone forming a discontinuity in the uniformity of the sections of pressure sensitive adhesive in the direction transverse to the edge.

Claim 3

A device as in claim 1, wherein the adhesive free zone is sufficiently great so that a user peeling off the cover sheet can feel the discontinuity.

Claim 4

A device as in claim 1, wherein said adhesive means forms continuous strips of adhesive transverse to the edge.

Claim 5

A device as in claim 3, wherein said securing means includes a plurality of strips of adhesive extending transverse to the edge between the zone and the edge.

Claim 6

A device as in claim 3, wherein said securing means includes pressure sensitive adhesive for removably bonding the cover sheet to the backing sheet.

Claim 7

A device as in claim 1, wherein said securing means includes pressure sensitive adhesive for bonding the cover sheet to the backing sheet removably.

Claim 8

A device as in claim 1, wherein said securing means includes adhesive for bonding the cover sheet to the backing sheet permanently.

Claim 9

A device as in claim 1, wherein said securing means includes the same material as said adhesive means and forms an extension of said adhesive means with the strip-shaped zone forming an interruption in said adhesive means.

Claim 10

A device as in claim 1, wherein said backing sheet further comprises three additional edges one of which is opposite to said edge.

Claim 11

A device as in claim 9, wherein said backing sheet has a row of perforations parallel to said one of said added edges for binding said backing sheet into an album.

Claim 12

A device as in claim 10, wherein said perforations include outwardly diverging slits for passing a binding ring therethrough.

Claim 13

A device as in claim 9, wherein said adhesive means is separated from two of said additional edges by adhesive free areas.

Claim 14

A device as in claim 1, wherein said cover sheet extends about said edge and is folded about said edge, said cover sheet having a second face, second securing means corresponding to said first securing means on said second face, second adhesive means corresponding to said first adhesive means on said second face and spaced from said securing means to form a second adhesive free strip-shaped zone extending parallel to the edge and corresponding to said first strip-shaped zone.

Claim 15

A device as in claim 1, further comprising a second cover sheet adjacent said first cover sheet, second securing means corresponding to said first securing means at said edge for bonding said second cover sheet, and second adhesive means corresponding to said first adhesive means for removably bonding said cover sheet to said backing sheet, said adhesive means being spaced from said securing means to form a second adhesive free strip-shaped zone extending parallel to the edge and spaced from the edge, said second zone being an extension of said first zone and corresponding to said first one.

Claim 16

A device as in claim 1, wherein said cover sheet is divided in a direction transverse to the edge for mounting items thereon.

Claim 17

An adhesive sheet device for mounting photographs and the like in an album, which comprises a relatively thick backing sheet; a plurality of parallel strips of relatively thin film of pressure sensitive adhesive on one surface of said backing sheet; said strips forming a plurality of aerating channels therebetween and defining with said channels a discontinuous overall adhering area, and a subsTantially uniplanar cover sheet of transparent material disengageably adhered to said adhering area and disengageable from said strips for insertion of an item beneath said cover sheet for clear viewing of the item through said transparent uniplanar cover sheet; said backing and said cover sheet having formed therein a row of perforations parallel to and adjacent to one edge thereof for binding said sheet device into an album; said cover sheet being formed with a separation line therein extending parallel to said row of performations inwardly of and closely adjacent to the latter, said backing sheet being further provided with a non-adhesive strip zone devoid of said adhesive zone and extending parallel to the separation lines but closely adjacent to the opposite edge of the sheet, said zone being spaced from the opposite edge of the sheet so that a portion of the adhering area is on one side of said zone and another portion of the adhering area is on another side of said zone, said zone forming an interruption in the adhering area greater than other interruptions in said adhering area in the direction transverse to the zone when such interruptions exist.

Claim 18

An adhesive sheet device for mounting photographs and the like in an album, which comprises a relatively thick backing sheet; a plurality of parallel strips of relatively thin film of pressure sensitive adhesive on one surface of said backing sheet; said strips forming a plurality of aerating channels therebetween and defining with said channels a discontinuous overall adhering area, and a subsTantially uniplanar cover sheet of transparent material disengageably adhered to said adhering area and disengageable from said strips for insertion of an item beneath said cover sheet for clear viewing of the item through said transparent uniplanar cover sheet; said backing and said cover sheet having formed therein a row of perforations parallel to and adjacent to one edge thereof for binding said sheet device into an album; said cover sheet being formed with a separation line therein extending parallel to said row of performations inwardly of and closely adjacent to the latter, said backing sheet being further provided with a non-adhesive strip zone devoid of said adhesive zone and extending parallel to the separation lines but closely adjacent to the opposite edge of the sheet, said zone being spaced from the opposite edge of the sheet so that a portion of the adhering area is on one side of said zone and another portion of the adhering area is on another side of said zone, said zone forming an interruption in the adhering area greater than other interruptions in said adhering area in the direction transverse to the zone when such interruptions exist.

Claim 19

A device as in claim 16, wherein said zone extends transverse to said strips and divides each of the strips so that one portion of each strip is on one side of the zone and one portion of each strip is on the other side of the zone.
