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.

Method of sealing a cigarette container

A method for bonding or joining plastic or metallic pipe using induced energy is provided. A susceptor is placed between the two pipes to be joined and a magnetic flux is induced onto the susceptor. The second pipe may be a coupling device. The magnetic flux may be induced by a tank circuit or an induction heating gun. The induction heating gun may be formed with a hinged heating head. The susceptor may be a perforated metal ring or a wire coil. The susceptor is coated with a material compatible with the pipes, for example, a plastic adhesive material, magnetic flux is an induction heating gun having a hinged heating head.

Inductive systems for bonding and joining pipes

An induction heating device includes a handle having a hollow interior and two opposite ends, a wrist connected to one end of the handle, a U-shaped pole piece having two spaced apart ends, a tank circuit including an induction coil wrapped around the pole piece and a capacitor connected to the induction coil, a head connected to the wrist and including a housing for receiving the U-shaped pole piece, the two spaced apart ends of the pole piece extending outwardly beyond the housing, and a power source connected to the tank circuit. When the tank circuit is energized and a susceptor is placed in juxtaposition to the ends of the U-shaped pole piece, the susceptor is heated by induction heating due to a magnetic flux passing between the two ends of the pole piece.

Induction heating coupler and annealer

An induction heating device includes an induction heating gun which includes a housing, a U-shaped pole piece having two spaced apart opposite ends defining a gap therebetween, the U-shaped pole piece being mounted in one end of the housing, and a tank circuit including an induction coil wrapped around the pole piece and a capacitor connected to the induction coil. A power source is connected to the tank circuit. A pull test machine is provided having a stationary chuck and a movable chuck, the two chucks holding two test pieces bonded together at a bond region. The heating gun is mounted on the pull test machine in close proximity to the bond region of the two test pieces, whereby when the tank circuit is energized, the two test pieces are heated by induction heating while a tension load is applied to the two test pieces by the pull test machine to determine separation strength of the bond region.

Induction heating coupler

An induction heating head includes a length of wire having first and second opposite ends and being wound in a flat spiral shape to form an induction coil, a capacitor connected to the first and second ends of the wire, the induction coil and capacitor defining a tank circuit, and a flexible, elastomeric body molded to encase the induction coil. When a susceptor is placed in juxtaposition to the body, and the tank circuit is powered, the susceptor is inductively heated.
