Abstract: A method for producing an elastomeric component, preferably an elastomeric sealing component, including an elastomer body and a printed structure, preferably a printed electronic structure or circuit, on a surface of the elastomer body. The method includes: a. providing a planar foil of thermoplastic material having a printable surface; b. printing a structure onto the printable surface to obtain the printed structure; c. providing an elastomer substrate for forming the elastomer body; d. placing the planar foil with the printed structure onto the elastomer substrate; and e. laminating the combined planar foil and elastomer substrate by applying heat and pressure. The elastomeric component is obtained in that the elastomer substrate is formed to the shape of the elastomer body before step d); the elastomer substrate is formed to the shape of the elastomer body during lamination; or the elastomer substrate is formed to the shape of the elastomer body after lamination.

Abstract: A closure arrangement for a vessel containing a pharmaceutical substance, having a stopper, a metal cap, for securing the stopper on the vessel, and an overcap made of plastic, wherein, for the purpose of identifying contents of the vessel, a wirelessly readable, electrical memory unit is connected to the closure arrangement. In order for a closure arrangement of the type in question to be improved further, in particular in respect of tamper-evident sealing the memory unit is operatively connected both to the overcap and to the stopper, and the operative connection has a lasting effect on the memory unit when the overcap is torn off.
