A tamper-evident product (10, 110, 210) and related methods of production. A container (12, 112, 212) includes a neck (24, 24', 124, 224), and a tamper-evidencing component (11, 11', 111, 211) separate from the container and carried by the neck of the container in direct contact with a corresponding portion of the container neck. The component is composed of material that has higher thermal conductivity than that of a material of the container so as to concentrate heat in the corresponding portion of the container neck. The neck is thermally responsive to application of heat pursuant to tampering with the product by at least one of the following responses: an irreversible change in visual appearance of the corresponding portion of the container neck, or fracture of the container neck at the corresponding portion of the container neck. |
