    摘要： A method and apparatus are disclosed for sealing a metal end to an end of a non-metal body of a food container. The method includes placing the metal end onto the end of the non-metal body and inducing electrical currents in the peripheral portion only of the metal end to heat the peripheral portion. The peripheral portion is heated to a temperature and for a time sufficient to melt the non-metal end of the body. The inductive heating is then ceased to allow the molten material to re-solidify forming a bond and a seal with the metal end. The apparatus includes an annular copper coil sized and shaped to be positioned around or overlying the peripheral portion of the metal end. Passing radio frequency current through the copper coil induces heating currents in the peripheral portion of the end. Alignment features may be attached to the copper coil to align and center it with the metal end.

    摘要： A method of fusing thermoplastics components (12, 14) together comprises positioning an electrically conductive member (20) between opposing surfaces (16, 18) of two thermoplastic components to be fused together. The electrically conductive member comprises one or more perforations or spaces between solid material of the member. An electric current is caused to flow in the member so as to heat the member and melt at least some plastics material adjacent the opposing surfaces. The melted plastics material penetrates the perforations or spaces in the electrically conductive member, whereby melted plastics material from each component mixes so as to fuse the components.
