Abstract
Abstract The barrier in a closure liner can be formed with a distinctive design or logo when the closure liner is inserted in the cap by placing a male embossing die against the sealing layer of the closure liner with sufficient force to emboss an image in the foil layer. The embossing of indicia into the liner at the time the cap is to be placed on the container provides the manufacturer with his own distinctive logo which cannot be readily duplicated thus making the container closure tamper-resistant.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
156 words
A process for imparting indicia onto a closure liner for a container cap during application of the liner to the container cap having a top comprising the steps of: inserting a container cap into the liner inserting station of a lining machine, inserting a small amount of adhesive into the cap against the top of the cap, moving a closure liner laminate, comprising a layer of resilient material having a wax coating which coating contacts one surface of a layer of metal foil on an oposite surface of which is adhered a sealing layer suitable for sealing the laminate to a container, into said inserting station, cutting from said laminate a section of said laminate to fit into said cap, inserting the cut section of said laminate into said cap, pressing said section against the top of said cap, and imparting an embossed image into said laminate to define an embossed image in said metal foil.
Claim 2
Dependent Claim
156 words

Claim 3
Dependent Claim
46 words
A process according to claim 1 wherein said imparting step comprises placing a male die in intimate contact against said section of laminate when in said cap with sufficient force to form a deformation in said sealing layer and the foil layer to define an image.
Claim 4
Dependent Claim
55 words
A process according to claim 1 wherein said imparting step comprises placing said liner laminate in intimate contact with an embossing roller and rigidly supporting said resilient material to recess said sealing layer and metal foil to define said image in bas-relief on the surface of said metal foil adjacent said layer of resilient material.
Claim 5
Dependent Claim
54 words
A process according to claim 1 wherein said imparting step comprises intimately contacting a male die against said sealing layer of the section of laminate when in said cap with sufficient force to form a deformation in said sealing layer and the foil layer to define an image and not rupture the foil layer.
Claim 6
Dependent Claim
72 words
A process according to claim 1 wherein said imparting step comprises placing said liner laminate in intimate contact with an embossing roller and rigidly supporting said resilient material to apply sufficient force against said sealing layer with said embossing roller to deform said sealing layer and metal foil to define said image in bas-relief on the surface of said metal foil adjacent said layer of resilient material without rupturing said metal foil.
