Abstract
Two components ( ) to be joined to each other by vibration welding form on one or both sides of the bounding seam ( ) barrier means ( ) including a labyrinth seal. Means ( ) retaining attrition particles of the jointing faces ( ) in chambers ( ) by the attrition particles needing to migrate from chamber to chamber through damming gaps ( ) and to be deflected for passage through the next gap in each case. Due to this tortuous arrangement the attrition particles remain totally within the chamber system of the labyrinth seal ( ) and do not emerge from between the flanges ( ). When the seal ( ) is provided between the seam ( ) and the inner face ( ) of a container, the interior thereof is thus protected from soilage due to attrition particles.
