摘要： Closure construction for blow molded drums having an upstanding internally threaded neck. A closure plug with sealing gasket is screwed into the neck to provide a liquid tight seal. A plastic tamper evident overseal completely covers the plug and neck and is manually snapped in place so as to interlockingly engage the plug making both the plug wrench engaging structure and the overseal interlocking structure inaccessible without destruction of the overseal. A tear strip opening means is provided for authorized access.

摘要： An externally threaded closure plug for tightly closing off the internally threaded opening in shipping and storage containers such as drums, pails and the like. The plug is formed as a cup having a bottom wall and threaded cylindrical sidewall terminating in a circumferentially enlarged rim. Immediately beneath the rim of the plug is a gasket seat defined by the undersurface of the plug rim, the plug sidewall and an annular gasket retaining lip lying in a plane parallel to the undersurface of the plug rim. In use, the plug is screwed into and out of a container wall opening, having an internally threaded portion and an unthreaded portion, the sealing gasket being compressed between the unthreaded opening portion and the plug gasket seat and lying in close proximity to the internal thread. The gasket seat acts to prevent interengagement of the sealing gasket and the opening internally threaded portion.
摘要翻译： 一个外螺纹封闭塞，用于紧密关闭运输和储存容器（如鼓，桶等）中的内螺纹开口。 插塞形成为具有底壁和螺纹圆柱形侧壁的杯，终止于周向放大的边缘。 紧靠插头边缘的垫片座是由插塞边缘的下表面，插头侧壁和位于与插塞边缘的下表面平行的平面中的环形密封垫保持唇限定的垫圈座。 在使用中，插头被拧入并流出具有内螺纹部分和无螺纹部分的容器壁开口，密封垫片在无螺纹开口部分和插塞垫圈座之间被压缩并且紧邻内螺纹 。 垫圈座用于防止密封衬垫和开口内螺纹部分相互接合。
