  • Method of sealing a cigarette container
    Patent number: 6692423
    Abstract: A method for making a cigarette container wherein a hollow container body is constructed having an open end which includes a step portion defining a surrounding rim and interior abutments. A plug is prepared which is sized to be received between the rim of the body and to abut the abutments. The plug includes 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. An induction heating device is then located adjacent the open end of the body, and activated 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.
