    摘要： A plastic sealing ring is attached to a rim of a plastic container with an insert interposed between the rim and the sealing ring. By making the insert from a relatively rigid material, the insert can rigidify the sealing ring and hence the container. If the insert is made from an electrically conductive material, the insert can function to facilitate the induction welding of the sealing ring to the container. The sealing ring and insert can be formed as a unitary, composite sealing ring subassembly adapted for direct application to the rim of the container or they can be supplied as individual parts adapted to be applied to the rim of the container separately. In order to form the sealing ring subassembly, the sealing ring is molded from molten plastic. During the cooling of the sealing ring, the insert is positioned in a groove formed in the sealing ring. By maintaining the insert in the groove until the sealing ring completely cools, the shrinkage of the sealing ring during its cooling effectively locks the insert in the groove.

    摘要： Inductors for the induction welding of complicated welding patterns have been produced up to now mostly from copper plates which were provided with slits in the desired patterns by spark-cutting and embedded into plastic material. This method of manufacture is expensive and does not allow production of inductors with a very detailed pattern because, among other things, the slits must have a minimum width determined by the spark-cutting. By making the inductors in accordance with the present invention having a thin copper foil which is applied onto the surface of an insulating material, these difficulties are overcome and the desired inductor pattern can be produced in a simple manner by etching with the help of a suitable acid. This makes possible great accuracy of detail so that detailed inductors, e.g. for the packaging industry, can be manufactured at low costs.
