Abstract
Abstract Coins or other generally flat objects are packaged by being sandwiched between plastic layers at least one of which has an embossed surface juxtaposed to the coin or object to prevent tracing the surface contour thereof through said one layer. The plastic layer is of stiff plastic material such as polystyrene so that it cannot be opened by heat or will rupture or crack if tampered with. Indicia on a paper layer joined to the plastic layer is printed with ink which is soluble in aromatic hydrocarbon solvents such as toluol.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
120 words
A method of packaging generally flat objects comprising embossing a first layer of generally rigid tough plastic material, joining a preprinted second layer to said first layer so that the second layer overlies the depressions formed during said embossing step, positioning a heat-sealable third layer opposite said embossments on the first layer, positioning a generally flat object having transverse dimensions greater than the distance between adjacent embossments so that the object is between said first and third layers, heat sealing said first and third layers to enclose said object with the surface contour of the object being spaced from the first layer by said embossment so as to prevent tracing the surface contour of the object through said first layer.
Claim 2
Independent Claim
120 words
A method of packaging generally flat objects comprising embossing a first layer of generally rigid tough plastic material, joining a preprinted second layer to said first layer so that the second layer overlies the depressions formed during said embossing step, positioning a heat-sealable third layer opposite said embossments on the first layer, positioning a generally flat object having transverse dimensions greater than the distance between adjacent embossments so that the object is between said first and third layers, heat sealing said first and third layers to enclose said object with the surface contour of the object being spaced from the first layer by said embossment so as to prevent tracing the surface contour of the object through said first layer.
Claim 3
Dependent Claim
22 words
A method in accordance with claim 1 including embossing said third layer before the third layer is heat-sealed to the first layer.
Claim 4
Dependent Claim
26 words
A method in accordance with claim 1 wherein said first and third layers are made from polystyrene having a thickness of between 0.007 and 0.010 inches.
Claim 5
Dependent Claim
27 words
A method in accordance with claim 1 wherein said second layer is paper, said paper layer being preprinted with ink which is soluble in aromatic hydrocarbon solvents.
Claim 6
Dependent Claim
50 words
A method in accordance with claim 1 wherein said object is a coin, said layers being elongated strips, repeating the step of heat sealing the layers so as to enclose coins at spaced points along the strips, and cutting the strips across the heat-sealed joint to form discrete packaged coins.
