    • Disclosed are a closure construction for a container, such as a steel drum, embodying a flange member having an internally threaded opening adapted to be closed by an externally threaded cap, the flange member having an integral flange portion that is firmly secured in an offset portion of the container wall by means of spaced protuberances at the outer edge of the flange portion that are tightly engaged by the offset portion of the container wall, the protuberances being formed in the flange portion while the container wall adjacent the flange portion is secured against deformation, so that formation of the protuberances causes deformations of the container wall at and around the protuberances which firmly lock the flange member in place by engagement with the protuberances. Also disclosed are a method of making the closure construction, and apparatus for making it.
    • 公开了一种用于诸如钢桶的容器的封闭结构,其包括具有内螺纹开口的凸缘构件,所述凸缘构件具有适于由外螺纹盖封闭的内螺纹开口,所述凸缘构件具有牢固地固定在偏移部分中的整体凸缘部分 通过在凸缘部分的外边缘处与容器壁的偏移部分紧密接合的间隔开的突出部分,容器壁上的凸起形成在凸缘部分中,而与凸缘部分相邻的容器壁被固定以防变形 ,使得突起的形成引起容器壁在突起处和周围的变形,通过与突起的接合将凸缘构件牢固地锁定在适当的位置。 还公开了一种制造封闭结构的方法及其制造装置。
