    摘要： A drawn aluminum can shell has a peripheral crown which is double-seamed with an end portion of an aluminum can body to provide a can end having a generally flat center panel connected by an inclined curved or straight panel wall to an inclined inner wall of an annular U-shaped countersink. The countersink has an outer wall which connects with an inclined lower wall portion of a chuck wall at a junction below the center panel, and the chuck wall has a curved or inclined upper wall portion which connects with an inner wall of the crown. The chuck wall also has an intermediate wall portion forming a break, and the inner bottom width of the countersink is less than the radial width of the panel wall. The inclined upper wall portion of the chuck wall extends at an angle greater than the angle of the inclined lower wall portion of the chuck wall.

    摘要： A container assembly includes a container body having a side wall encircling an axis, and a metal end for attachment to an upper edge of the side wall via heat-sealing. The outer peripheral region is shaped prior to application to the container body such that an annular channel is defined between an inner chuck wall and an outer chuck wall of the metal end. The metal end is pushed straight onto the side wall such that the upper edge of the side wall is received into the channel. The surfaces of the side wall and the opposing surfaces of the chuck walls have heat-sealable material thereon. The metal end is heated to melt and fuse the heat-sealable layers, thereby sealing the metal end onto the side wall. The metal end is shaped such that the free edge of the outer chuck wall is not exposed.

    摘要： A container (1) is provided with a tear-off lid (2) having a take out opening covered by a tear-off foil (25). The cut edge (3) of the take out opening is bent back into the chuck wall (34) area. By this the bare cut edge is protected by the connection of lid and container body. This connection can be provided by a seaming connection.

    摘要： Closing of a metal container and the like using a special end closure. The open end portion of a container is outwardly folded to define a supporting ledge and a seaming or curling flange for the end closure. Such flange is folded or rolled inwardly to capture an end closure including a plastic frame that defines a dispensing opening and has bonded thereto an end panel to be peeled back to allow dispensing of product. A seaming flange is folded about a peripheral portion of an outer boundary of the frame member and then the two are enfolded generally flat above the supporting ledge of the container to form an inwardly directed seam. A modified end closure comprises a molded plastic frame member which matches the configuration of a ledge portion of the container so the seaming flange and peripheral border portion of the frame member can be rolled together in an inwardly directed curl. The closing operations can be performed without axial pressure on the container wall so they can be thinner than normal. Inwardly directed seams and curls protect the plastic end closure from damage caused by closing tools because dies and/or chucks contact the flange portion of the container rather than the end closure. A seal between the inwardly turned seam or curl and the border portion of the frame member can be enhanced by applying heat during formation thereof or during retorting of the container and product.

    摘要翻译： 使用特殊的端盖关闭金属容器等。 容器的开口端部向外折叠以限定支撑凸缘和端盖的接缝或卷边凸缘。 这种凸缘被折叠或向内卷起以捕获包括塑料框架的端盖，该框架限定了分配开口并且已经与其结合以被剥离的端板以允许产品的分配。 接缝法兰围绕框架构件的外边界的周边部分折叠，然后两者在容器的支撑凸缘上方大体平坦地折叠以形成向内的接缝。 改进的端盖包括与容器的凸缘部分的构造匹配的模制塑料框架构件，使得框架构件的接合凸缘和外围边界部分可以向内卷曲地卷绕在一起。 关闭操作可以在容器壁上没有轴向压力的情况下进行，因此它们可以比正常情况更薄。 向内引导的接缝和卷曲保护塑料端盖免受关闭工具的损害，因为模具和/或卡盘接触容器的凸缘部分而不是端盖。 通过在其形成期间或在容器和产品的蒸煮期间施加热量，可以增强向内转动的接缝或卷曲与框架构件的边界部分之间的密封。

    摘要： A pressure resistant basic shell, easy open end and can with easy open end, wherein the basic shell consists of a can seaming portion, a countersink portion, a ferrule arc portion, an upward extension portion of ferrule and a center panel from periphery to center in the cross section; the countersink portion also consists of a sixth arc portion and a second straight portion, and the sixth arc portion and the second straight portion are connected in a tangent way, and the second straight portion and the ferrule arc portion are connected in a tangent way; the center of the sixth arc portion is located below the upper surface of the center panel. The break probability under the failure of pressure resistance is lowered to 0.05%˜2.5%, which significantly improves the safety of use.
