摘要： Ends for cans are made in a single press, eliminating the need for separate shell and conversion presses, balancers, track work, and other equipment, as compared to existing can end manufacturing systems, while reducing floor space and capital investment requirements for installation of a new can end line. A sheet of end material or stock is introduced into the press and fed to a series of work stations. The sheet is maintained in a substantially continuous and void free state as the work stations perform forming operations on the sheet of material to form one or more ends therein. After the forming operation is complete, the end is ejected from the press. The maintenance of the sheet of material in a substantially continuous and void free state permits precise movement of the sheet through the press, and registration of the sheet relative to the tooling in the press. This precise movement and maintenance of registration results in a single press capable of operation at high speeds to produce large volumes of ends, while doing so in a reliable and cost-effective manner. In a preferred embodiment, the typical shell conversion operations are performed first on the sheet of end material, while maintaining the sheet in a substantially planar and void free state, followed by a shell forming operation in which the panel and countersink features are formed and the completed end blanked in a single stroke at the very end of the forming operations.
摘要翻译： 罐头的结束是在一个新闻中制作的，与现有的罐头制造系统相比，不需要单独的壳和转换压力机，平衡器，履带工作和其他设备，同时减少了安装一个 新的可以结束线。 将一张末端材料或原料引入压机中并供给一系列工作站。 当工作台在材料片上进行成形操作以在其中形成一个或多个端部时，片材保持在基本上连续且无空隙的状态。 成型操作完成后，将末端从压机中排出。 基本上连续且无空隙状态的材料片的维护允许片材通过压力机的精确移动，并且片材相对于压机中的工具进行配准。 这种注册的精确移动和维护导致能够以高速度运行的单个压力机产生大量的端部，同时以可靠和成本有效的方式进行。 在优选实施例中，典型的壳转换操作首先在端部材料片上进行，同时将片材保持在基本平坦且无空隙的状态，随后进行壳形成操作，其中形成面板和埋头孔特征，并且 在成型操作结束时，完成的终点在一个冲程中消隐。

摘要： The product and method of manufacturing a tab having a rivet island window and adapted to be secured to a container end, including the steps of forming a first dimple at a first end position of the window and a second dimple at a second end position of the window, formed as depressed regions of metal residing outside the central plane of the metal. The method includes punching a first blank in the first dimple and a second blank in the second dimple, and subsequently bending the edge regions around the first and second blank to form a bend of the metal away from the central plane. The central region of the window is formed between and joining the blanks, and a rivet opening is formed, adapted to receive a rivet for staking the tab to a container end.

摘要： A container has a selectively openable panel defined at least in part by a frangible score groove in a surface of the container. The frangible score groove is selectively fracturable by a lifting action administered by a user to a secured to the container. The tab has a nose portion separated from a lift end by a central webbing. The central webbing has a hinge region and a rivet island. The rivet island is at least partially surrounded by a first void region. The central webbing also has a grab portion at the lift end of the tab. The grab portion has an enclosed region defining a billboard surface. The billboard surface has a top side and a bottom side opposite the top side. A bead created by displacing the material of the central webbing is located on the billboard surface. A pigment-carrying layer covers at least a portion of the billboard surface. A tactile indicium is located on the billboard surface.

摘要： A can end member has a center panel, a circumferential chuck wall, and a transition wall. The center panel is centered about a longitudinal axis and has a peripheral edge. The center panel also has a step portion located radially outwardly from the longitudinal axis. The step portion has an annular convex portion joined to an annular concave portion and displaces at least a portion of the center panel vertically in a direction parallel to the longitudinal axis. The curl defines an outer perimeter of the end member. The circumferential chuck wall extends downwardly from the curl to the transition wall. The transition wall connects the chuck wall with the peripheral edge of the center panel. The transition wall comprises a folded portion. The folded portion has a first leg, a second leg, and a third leg. The first leg is directly connected to the chuck wall and joined to the second leg by a concave annular portion. The second leg is joined to the third leg by a convex annular portion, and the third leg is joined to the center panel. The convex annular portion has a radius of curvature greater than 0.002 ins.

摘要： The present invention is a reformed container end and a method of forming the container end. The container end includes a center panel surrounded by a countersink having an inner wall, an outer wall, and a countersink bottom. The countersink bottom includes a first arcuate segment having a small radius and a second arcuate segment having a larger radius. The container end may also include a portion wherein the center panel is slightly expanded and the inner wall is further reformed to direct potential buckling away from the nose of a pour opening panel.
