摘要:
A container (e.g., an 8 oz. milk container) formed of paperboard, or the like, is formed with an aperture. A plastic disk is attached to the paperboard over the aperture by thermoplastic welding or other means. The disk has a frangible area which is opened to dispense contents. Typically the frangible area is penetrated by the end of a drinking straw. For aseptic packaging, the paperboard may be lined with a barrier, such as foil. Alternatively foil may be attached to the disk and welded to the paperboard surrounding the aperture or welded to a foil or polyethylene liner for the paperboard.
