Abstract
Abstract A semi-laminated security pouch for a tamper proof identification card is disclosed. The identification card to be protected by the security pouch has a glass bead security coating on a front face which provides an indication if indicia are tampered with on the face of the card. The pouch comprises front and rear film leaves with a heat reactivatable adhesive layer on the rear leaf card-facing surface. The rear surface of the card is centered against the rear leaf for lamination. The front leaf does not have a heat reactivatable adhesive layer thereon since such a layer would destroy the retroreflective visual characteristics of the glass bead security coating. The front leaf card-facing surface does, however, have the bond promoting coating thereon such that when the pouch is assembled, peripheral portions of the front leaf come in contact with peripheral portions of the rear leaf extending beyond the card edges. The bond promoting coating permits adhesion between the polyester material front leaf and the heat reactivatable adhesive at peripheral portions of the rear leaf.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
165 words
A semi-laminated tamper proof identification card assembly, comprising: (a) an identification card having identifying indicia on a front face and a glass bead security coating means on said front face for providing data alteration security which becomes substantially ineffective when a heat reactivatable adhesive layer is melted in contact therewith: (b) transparent front and rear film leaves; (c) a heat reactivatable adhesive layer on said rear leaf laminating the rear leaf to a rear surface of the card; and (d) the front leaf being positioned over and in contact with but not laminated to the security coating means on the card and said front leaf not having a heat reactivatable adhesive layer in contact with the security coating means, said front leaf being bonded to the rear leaf by said heat reactivatable adhesive at peripheral portions of the front leaf substantially surrounding outer edges of the card, a bond promoting means being provided for adhering the front leaf peripheral portions to the heat reactivatable adhesive.
Claim 2
Dependent Claim
165 words
A semi-laminated tamper proof identification card assembly, comprising: (a) an identification card having identifying indicia on a front face and a glass bead security coating means on said front face for providing data alteration security which becomes substantially ineffective when a heat reactivatable adhesive layer is melted in contact therewith: (b) transparent front and rear film leaves; (c) a heat reactivatable adhesive layer on said rear leaf laminating the rear leaf to a rear surface of the card; and (d) the front leaf being positioned over and in contact with but not laminated to the security coating means on the card and said front leaf not having a heat reactivatable adhesive layer in contact with the security coating means, said front leaf being bonded to the rear leaf by said heat reactivatable adhesive at peripheral portions of the front leaf substantially surrounding outer edges of the card, a bond promoting means being provided for adhering the front leaf peripheral portions to the heat reactivatable adhesive.
Claim 3
Dependent Claim
166 words
A semi-laminated tamper proof identification card assembly comprising: (a) an identification card having identifying indicia on a front face and a glass bead security coating means on said front face for providing data-alteration security, the coating means losing its data-alteration security when laminated thereover with a heat reactivatable adhesive layer; (b) transparent polyester front and rear film leaves, said card being between the leaves; (c) a heat reactivatable adhesive layer on a card facing surface of the rear leaf but not on portions of the front leaf adjacent the security coating means; (d) the front and rear leaves each having a peripheral portion which extends beyond and at least partially surrounds the identification card when the card is on the leaves; and (e) a bond promoting layer means for improving adhesion of a card facing surface of the polyester front leaf to the heat reactivatable adhesive layer of the rear leaf, the layer means being provided at least on the peripheral portion of the front leaf.
Claim 4
Dependent Claim
166 words
A semi-laminated tamper proof identification card assembly comprising: (a) an identification card having identifying indicia on a front face and a glass bead security coating means on said front face for providing data-alteration security, the coating means losing its data-alteration security when laminated thereover with a heat reactivatable adhesive layer; (b) transparent polyester front and rear film leaves, said card being between the leaves; (c) a heat reactivatable adhesive layer on a card facing surface of the rear leaf but not on portions of the front leaf adjacent the security coating means; (d) the front and rear leaves each having a peripheral portion which extends beyond and at least partially surrounds the identification card when the card is on the leaves; and (e) a bond promoting layer means for improving adhesion of a card facing surface of the polyester front leaf to the heat reactivatable adhesive layer of the rear leaf, the layer means being provided at least on the peripheral portion of the front leaf.
Claim 5
Dependent Claim
22 words
The assembly of claim 2 in which the bond promoting layer means substantially covers the card facing surface of the front leaf.
Claim 6
Dependent Claim
39 words
The assembly of claim 2 in which the peripheral portion of the leaves completely surrounds the card and the card facing surface of the peripheral portion of the front leaf is completely covered with the bond promoting layer means.
Claim 7
Dependent Claim
21 words
The assembly of claim 2 in which the front and back leaves are joined to one another at a fold line.
Claim 8
Dependent Claim
52 words
The assembly of claim 2 in which the glass bead security coating means provides a retroreflective visual effect which is altered when indicia on the card is tampered with, and a lamination with heat reactivatable adhesive over the coating substantially altering the retroreflective visual effect as the adhesive encapsulates the glass beads.
Claim 9
Dependent Claim
12 words
The assembly of claim 2 in which the card comprises paper material.
Claim 10
Dependent Claim
12 words
The assembly of claim 2 in which the card comprises plastic material.
Claim 11
Dependent Claim
129 words
A semi-laminating security pouch for an identification card having identifying indicia on a front face and a glass bead security coating on said front face which is rendered ineffective when coated by a heat reactivatable adhesive layer, comprising: (a) a front transparent polyester film leaf; (b) a rear transparent polyester film leaf; (c) a heat reactivatable adhesive layer on a card-facing surface of the rear leaf; (d) the front and rear leaves each having a peripheral portion which extends beyond and surrounds the identification card when the card is centered on the leaves; and (e) a bond promoting layer means on the peripheral portion at a card-facing surface of the first leaf, a heat reactivatable adhesive layer not being provided on a card-facing surface portion of the front leaf.
Claim 12
Dependent Claim
129 words
A semi-laminating security pouch for an identification card having identifying indicia on a front face and a glass bead security coating on said front face which is rendered ineffective when coated by a heat reactivatable adhesive layer, comprising: (a) a front transparent polyester film leaf; (b) a rear transparent polyester film leaf; (c) a heat reactivatable adhesive layer on a card-facing surface of the rear leaf; (d) the front and rear leaves each having a peripheral portion which extends beyond and surrounds the identification card when the card is centered on the leaves; and (e) a bond promoting layer means on the peripheral portion at a card-facing surface of the first leaf, a heat reactivatable adhesive layer not being provided on a card-facing surface portion of the front leaf.
