Abstract:
A method for making a cigarette container comprising the steps of:constructing a hollow container body having an open end, the open end including a step portion defining a surrounding rim and interior abutments; preparing a plug which is sized to be received between the rim of the body and to contact the abutments, the plug including a main plate, a metal layer attached to the main plate, and a heat activated adhesive located adjacent the metal layer and positioned to be immediately adjacent the step portion when the plug is inserted in the open end of the body and the plug contacts the abutments; placing the main plate in the open end of the body so that the adhesive is disposed between the step portion and the main plate; locating an induction heating device adjacent the open end of the body; and activating the induction heating device to heat the metal layer and hence to heat the adjacent adhesive so that after cooling the plug is bonded to the body by the adhesive and the plug thus permanently closes the open end of the body.
