自动卸压盖
摘要：
容器的封盖(10)，包括一基本上为圆形的基座(20)，一个从基座外围延伸的裙部(30)，一个以环面形式形成的的密封塞(50)和一个基本沿半径方向位于基座(20)表面上的肋(70)，该肋一端与密封塞(50)的径向内表面相接触，用于将基座(20)的中心相对于裙部(30)的运动传递至密封塞(50)，使密封塞(50)沿径向向内被拉伸，从而释放出容器内部多余的压力，在平行于基座(20)的平面内，肋(70)与密封塞(50)的径向内表面相接触的端部比肋(70)的另一端薄。
摘要（英）：

A closure 10 for a container, comprises a substantially circular base 20, a skirt 30 extending from the periphery thereof, a bore seal 50 in the form of an annulus and a rib 70 lying on the surface of the base 20 in a substantially radial direction and in contact with the radially inner surface of the bore seal 50 at one end for transferring any movement of the centre of the base 20, relative to the skirt 30, to the bore seal 50 such that the bore seal 50 is pulled radially inward to allow venting of excess pressure within the container, wherein the end of the rib 70 in contact with the radially inner surface of the bore seal 50 is substantially thinner, in a plane parallel to the base 20, than the other end of the rib 70.
