    • A can end having a countersink bead, an inclined chuck wall and a strong seam, resists distortion from its circular profile when subjected to thermal processing or when packaging carbonated beverages. This high hoop strength affects the manner in which the can end ultimately fails when placed under extreme abuse conditions, even if buckle pressure performance is within industry specified standards. The can end of the invention has control features introduced which control the failure mode whilst maintaining specified buckle pressure performance. In one embodiment, the can end has a two part wall and a control feature that comprises expansion of the countersink bead to act as a trigger for local peaking, together with a groove in the chuck wall which prevents the peaking force from being concentrated at a single point which could result in leaking by the production of a pin hole.
    • 具有锪孔珠,倾斜卡盘壁和强力接缝的罐端可以在经受热处理时或当包装碳酸饮料时抵抗其圆形轮廓的变形。 即使扣压性能在行业规定的标准之内,这种高箍强度会影响罐头最终在极端恶劣条件下的失败方式。 本发明的罐端部具有控制特征,其控制故障模式同时保持规定的带扣压力性能。 在一个实施例中,罐端部具有两部分壁和控制特征,其包括使锪孔焊道膨胀以用作局部峰化的触发器,以及卡盘壁中的凹槽,其防止峰值力集中在 单点可能导致产生针孔泄漏。

    • A thermal process for treating a metal to improve at least one structural characteristic of the metal comprising: placing a metal with a metal temperature within a thermal control apparatus, introducing a cryogenic material to decrease the metal temperature, while preventing over-stressing of the metal, to a first target temperature ranging from −120 degrees Fahrenheit to −380 degrees Fahrenheit at a first temperature rate, ranging from degrees Fahrenheit per minute to 20 degrees Fahrenheit per minute, stopping the introduction of cryogenic material once the first target temperature is reached, and increasing the chamber temperature to a second target temperature ranging from 0 degrees Fahrenheit to 1400, and increasing the metal temperature to the second target temperature at a second temperature rate ranging from 0.25 degrees Fahrenheit per minute to 20 degrees Fahrenheit per minute, resulting in a treated metal without fractures.
    • 一种用于处理金属以改善金属的至少一种结构特征的热处理方法,包括:将具有金属温度的金属放置在热控制装置内,引入低温材料以降低金属温度,同时防止金属的过度应力 到第一温度范围为-120华氏度至-380华氏度的第一个目标温度,温度范围为每分钟华氏度至每分钟华氏20度,一旦达到第一目标温度就停止引入低温材料, 并将室温升至0华氏度至1400度的第二目标温度,并以每分钟0.25华氏度至20华氏度的第二温度升高金属温度至第二目标温度,得到 经处理的金属无裂缝。
