摘要： A thin walled metal container is formed with a bottom wall having a substantially flat central panel connected to a container side wall through an annular rest radius defining an annular support surface for the container. The annular rest radius includes an outer connecting web portion leading into the container side wall and an inner connecting web portion leading into the central panel. In the preferred embodiment, these connecting web portions are permanently joined to each other by welding or adhesive bonding to resist column loading forces acting through the side wall and internal pressure forces acting through the central panel which have the effect of unrolling the annular rest radius. Since these curved opposing portions of the rest radius are immobilized to resist column and internal pressurization, a thinner gauge metal can be used to satisfy design parameters and achieve cost and metal reduction savings. A method of reforming an annular rest radius in the bottom wall of a drawn and ironed container is also disclosed.
摘要翻译：薄壁金属容器形成有底壁，该底壁具有通过限定用于容器的环形支撑表面的环形保持半径连接到容器侧壁的基本平坦的中心板。环形休止半径包括通向容器侧壁的外部连接腹板部分和通向中央面板的内部连接腹板部分。在优选实施例中，这些连接腹板部分通过焊接或粘合结合而彼此永久地接合，以抵抗通过侧壁作用的柱加载力和通过中心面板作用的内部压力力，其具有展开环形半径的作用。由于其余半径的这些弯曲的相对部分被固定以抵抗柱和内部加压，所以可以使用更薄的金属来满足设计参数并实现成本和金属减少的节省。还公开了一种在拉制和熨烫的容器的底壁中重新形成环形半径的方法。

摘要： An easy-open wall is provided for a container and comprises curvilinear score means in such wall defining at least the major part of the peripheral outline of a panel which is partially severable from the wall to define a dispensing opening in the wall. A tab is attached in a nondetachable manner against the wall outwardly of the panel with the tab having a forward portion which overlies part of the panel and having a rear portion. The rear portion is easily grasped and lifted to urge the forward portion against the panel to thereby sever the major portion of said panel along the score means and move it within the container with a portion of the wall holding the panel securely thereto. The tab may be provided with means for fastening it flatly against the wall after using the tab to sever the panel.

摘要： An easy-open, reseable closure assembly for a beverage can (10) comprises a metal lid (12) and two threadedly connected molded plastic closure elements (40, 60) with engageable annular reseal surfaces (46, 76). The lid is scored (30) to define a circular tear panel (28) and a hinge (32). The spout element (40) is attached to the lid (12) with the bottom surface of the cap element (60) directly above and aligned with the periphery of the tear panel (28). Rotation of the cap element (60) by a user ruptures the tear panel and pivots the tear panel (28) downward about the hinge (32), providing a passage through the spout element (40) for pouring and driking. Initial rupture and rupture propagation of the tear panel (28) is controlled by the spacing of the cap element (60) from the tear panel (28) and their configurations. When the cap element (60) is replaced on the spout (40), reseal surfaces (46, 76) engage.
摘要翻译：一种用于饮料罐（10）的容易打开，可重新封闭的封闭组件包括金属盖（12）和两个具有可接合的环形再密封表面（46,76）的螺纹连接的模制塑料封闭元件（40,60）。盖子被刻痕（30）以限定圆形撕裂板（28）和铰链（32）。喷嘴元件（40）以盖元件（60）的底表面直接安装在盖（12）上并且与撕裂板（28）的周边对齐。使用者使用盖元件（60）的旋转使撕裂板破裂，并使撕裂板（28）围绕铰链（32）向下转动，从而提供通过喷口元件（40）的通道，用于倾倒和流动。撕裂板（28）的初始破裂和断裂传播由盖元件（60）与撕裂板（28）的间距及其构型控制。当在喷嘴（40）上更换盖元件（60）时，再密封表面（46,76）接合。

摘要： A thin-walled metal container is formed with a bottom wall which is substantially flat and connected to a container side wall through a curved wall portion located at the periphery of the flat bottom wall. A stacking support member is attached to the lower surface of the bottom wall to define a rest surface for supporting the container on a horizontal surface, The stacking support member is made of foam material to prevent `sweating` of the container on a table surface while also minimizing scratching, Other non-metallic materials may function as the stacking support member.

摘要： An easy-open construction for a container wherein a panel principally defined by a rupturable score line in a wall is opened by operating a tab having one end adapted to press against the panel at a position spaced from the score line and overlying only a small portion of the opening left by the panel in its opened position. The other end of the tab is liftable to open the panel and is returnable directly to its original position next to the wall. The tab and panel remain secured to the wall after the panel has been moved to its open position.

摘要： A can is formed including a body having a bottom wall with an electromagnetically formed contoured sidewall extending therefrom and a necked end. The open end of the sidewall is first pre-necking to form a reduced diameter section. Thereupon, the sidewall is electromagnetically formed to form an outwardly expanding contoured sidewall. The can is then subjected to a necking process proximate the reduced diameter section to achieve a further reduced diameter conical necked end. The necking process may be performed by radially inwardly advancing an external forming member into contact with the sidewall against counterpressure provided by a pair of relatively axially displaceable inner members disposed within the can interior. Alternatively, the necking process may be spin flow necking.
摘要翻译：罐形成包括具有从其延伸的电磁形状轮廓侧壁的底壁的主体和颈缩端。侧壁的开口端首先进行颈缩以形成直径减小的部分。于是，侧壁被电磁地形成以形成向外膨胀的轮廓侧壁。然后将罐接近缩径部分进行缩颈处理，以实现进一步减小直径的锥形颈端。缩颈过程可以通过径向向内推进外部形成构件与侧壁接触，抵抗由设置在罐内部中的一对相对可轴向移动的内部构件提供的反压。或者，颈缩过程可以是旋转颈缩。
