Abstract A miniature plastic container, particularly adapted for cosmetic preparations and the like, in which the body of the container is closed at one end by a wall, its opposite end being adapted to receive a pluglike closure which may be covered by a cap removable for dispensing the preparation. The plug closure also is preferably made of plastic. Surrounding an area of the pluglike closure, which may be located near its inner end, is a thin metal ring engaging the inner wall-surface of the container body. The thus assembled container, after filling, but preferably before filling, may have applied to the plug area a short induction coil with a medium-high-frequency current, which heats up the metal ring, melting the neighboring layer of plastic and resulting in a thermal bond between the container body and the pluglike closure.
