  • Publication number: 20120255945
    Abstract: 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.

  • Patent number: 4676378
    Abstract: A bag pack formed of multiple stacked handle bags having aligned mounting apertures defined through the handles thereof for reception of mounting rods therethrough. The apertures are formed by partially severed flaps which are in turn bonded together to maintain aperture alignment. The flaps are integral with the bags along minor easily severed areas for a freeing of the bags upon a severance of the flaps simultaneous with or subsequent to reception of the mounting rods through the apertures.
