Abstract: The present disclosure relates to a sample and an evaluation method for measuring galvanic corrosion between a conductive coating and a protected substrate. A micropore insulating layer is arranged between the conductive coating and the substrate, the micropore insulating layer is composed of an insulating material and contains a micropore structure, the micropore structure can form an ion pathway on the surfaces of the conductive coating and the substrate after being filled with a conductive medium, and the substrate and the conductive coating are both connected with an independent leading wire. The sample of the present disclosure can evaluate galvanic corrosion between a conductive coating and other conductive materials more fully.

Abstract: A cap for use on a bottle or other container provides child resistant features and tamper evident features while simplifying packaging. The cap includes a collar that will slide over a bead of the container and resist removal after installation. The outer diameter of the collar is preferably substantially the same diameter as that of the bottom of an outer cap element to provide an aesthetically pleasing appearance.
