摘要： A safety cap is adapted to assume a locked position on the neck of a container at which an annular cap rib rides within the concavity provided by an annular neck recess. In order to remove the cap, it must first be pulled outwardly to break this interengagement. Thereafter, the cap need only be rotated or turned to free the cap from neck threads. In order to mount the cap on the container neck, the cap is initially twisted to cause interengagement of the threads of the cap with the threads of the container neck. The threads are so arranged that when the cap rib engages the upper part of the neck recess, the last turn will force the rib into the recess and at the same time clear the threads from one another. In this position the cap will turn freely relative to the neck with the cap rib disposed within the neck recess.

摘要翻译： 安全帽适于在容器的颈部上呈现锁定位置，在该颈部上环形帽肋在由环形颈部凹口提供的凹部内骑行。 为了去除帽子，必须先向外拉，以打破这种相互联系。 此后，盖子只需旋转或转动即可从颈部螺纹上卸下盖子。 为了将盖子安装在容器颈部上，盖子最初被扭曲以使盖子的螺纹与容器颈部的螺纹相互接合。 螺纹的布置使得当帽肋接合颈部凹槽的上部时，最后的转弯将迫使肋进入凹部并且同时将线从彼此清除。 在该位置，盖子将相对于颈部自由转动，并且帽肋设置在颈部凹口内。
