    • PROBLEM TO BE SOLVED: To provide a more economic method of providing beverage containers having an expanded diameter portion, wherein the method is easily incorporated into an in-line process.SOLUTION: An expansion die 5 for manufacturing metal containers includes a work surface 10 including a progressively expanding portion 15 and a land portion 20; and an undercut portion 25 positioned following the land portion 20 of the work surface 10. A process for manufacturing shaped containers includes: providing a container stock having a first diameter; expanding at least a portion of the container stock to a second diameter with at least one expansion die 5; and forming an end of the container stock to accept a container lid.
    • 要解决的问题:为了提供一种更经济的提供具有膨胀直径部分的饮料容器的方法,其中该方法容易地并入到在线方法中。 解决方案:用于制造金属容器的膨胀模具5包括:工作表面10,其包括逐渐膨胀部分15和陆部20; 以及设置在工作表面10的陆部20之后的底切部分25.一种用于制造成形容器的方法包括:提供具有第一直径的容器坯料; 用至少一个膨胀模具5将容器坯料的至少一部分膨胀至第二直径; 并形成容器坯料的端部以接收容器盖。 版权所有(C)2012,JPO&INPIT

    • A method of forming a metal container comprises: curling outward a top edge of the metal container to form a curl and expanding a diameter of a first section of the metal container to form a first expanded section; wherein at least part of the first expanded section is below the curl. In some embodiments, the steps of curling outward a top edge of the metal container to form a curl and expanding a diameter of a first section of the metal container to form a first expanded section are performed in a single stroke of a single die. In some embodiments, the step of expanding a diameter of a first section of the metal container to form an expanded section is performed after the step of curling outward a top edge of the metal container to form a curl.
    • 一种形成金属容器的方法,包括:向外卷曲所述金属容器的顶部边缘以形成卷曲并且扩大所述金属容器的第一部分的直径以形成第一扩展部分; 其中第一膨胀部分的至少一部分在卷曲下方。 在一些实施例中,在单个冲模的单个冲程中执行向外卷曲金属容器的顶部边缘以形成卷曲并且扩大金属容器的第一部分的直径以形成第一膨胀部分的步骤。 在一些实施例中,在将金属容器的顶部边缘向外卷曲以形成卷曲的步骤之后执行扩展金属容器的第一部分的直径以形成膨胀部分的步骤。
