    • A closure 9 for the open mouth 2 of a container includes a main body 8 and sealing means which extends around the periphery of the main body. The sealing means has a sealing edge 17 which is adapted to engage a sealing surface formed on the container, and a resiliently flexible web 16 which connects the sealing edge to the main body. The web is movable between a relaxed condition (Figure 1), in which the diameter of the sealing edge 17 is at a maximum, and a sealing condition (Figure 13), in which the diameter of the sealing edge 17 is less than maximum. When the closure operatively closes the opening 2 in the container the web 16 is moved to the sealing condition, and the resilience of the web material serves to press the sealing edge 17 against the sealing surface 1. Preferably the web 16 in its relaxed condition has a frusto-conical form which diverges upwardly and the sealing edge 17 is formed on the upper and outer edge of the web 16.
    • 用于容器的开口2的封闭件9包括主体8和围绕主体的周边延伸的密封装置。 密封装置具有适于接合形成在容器上的密封表面的密封边缘17以及将密封边缘与主体连接的弹性柔性腹板16。 腹板可以在其中密封边缘17的直径最大的松弛状态(图1)和密封边缘17的直径小于最大值的密封状态(图13)之间移动。 当封闭件操作性地关闭容器中的开口2时,网16移动到密封状态,并且网材料的弹性用于将密封边17压靠在密封表面1上。优选地,处于其松弛状态的网16具有 向上分散的截头圆锥形形式,并且密封边缘17形成在腹板16的上边缘和外边缘上。

    • A lid for use with containers such as drums, pails, tubs and cups which is formed as a singular unit from molded plastic and which incorporates a peripherally disposed skirt (34) configured along with a rim structure (40) to provide primary and secondary latching features. A parting groove (60) is positioned within the skirt assembly (34) in conjunction with a tear ring (42) which functions to remove the primary latching assembly following the initial closure of the container with the lid (20). Prior to such removal, the primary latching assembly in­cludes an interference lug having a compression section which engages the upwardly disposed surface (86) of an engaging groove (84) formed within the rim structure (82) of the container. After removal of the primary latching assembly, a secondary latching arrangement is maintained which includes the upper skirt portion (64), a generally semi-cylindrically shaped rim interior portion having a bead conforming surface (94) nestable in seating adjacen­cy with the upwardly disposed container rim bead (90) and a detent defining ridge (102) formed integrally with the skirt upper portion interior surface at a location for snap-on engagement with the rim structure (82) of the container.
    • 一种用于容器的盖子,例如桶,桶,桶和杯子,其由模制塑料形成为单一单元,并且包括与边缘结构(40)一起配置的周边设置的裙部(34),以提供初级和次级锁定 特征。 分离凹槽(60)与撕裂环(42)一起定位在裙部组件(34)内,该撕裂环用于在具有盖(20)的容器初始封闭之后移除主闩锁组件。 在这种移除之前,主闩锁组件包括具有压缩部分的干涉凸耳,所述压缩部分接合形成在容器的轮缘结构(82)内的接合凹槽(84)的向上设置的表面(86)。 在移除主闩锁组件之后,保持辅助闩锁装置,其包括上裙部部分(64),大致半圆柱形形状的轮缘内部部分,其具有可与向上设置的容器相邻配合的胎圈一致表面(94) 边缘凸缘(90)和与裙部上部内表面一体形成的止动限定凸缘(102),用于与容器的边缘结构(82)卡扣接合。
