Abstract: A closure valve for a container is disclosed. The container has a cap region defining a substantially tubular channel through which contents of a container can exit. The valve has a body portion (20) housed within the channel and moveable between a closed position, which prevents flow of contents, and an open position which allows flow. Internal pressure within a container, acts to cause movement to the open position.A head portion (28) of the body portion (20) seals the outer aperture of the channel when in the closed position.A flange (21) is located within and spans the channel, whereby excess pressure within the container acts on the flange (21) to move the body portion to an open position, in order to allow fluid contents to pass therethrough, the flange includes one or more apertures. Moreover, the closure valve includes one or more resilient elements (30) operably connected to the valve body portion (20) and biased to retain the body portion (20) in the channel closing position.

Abstract translation: 公开了一种用于容器的封闭阀。 容器具有限定容器的内容物可以通过其排出的基本管状通道的帽区域。 阀具有容纳在通道内的主体部分（20），并且可在阻止内容物流动的关闭位置和允许流动的打开位置之间移动。 容器内的内部压力用于使运动到打开位置。 当处于关闭位置时，主体部分（20）的头部（28）密封通道的外孔。 凸缘（21）位于通道内并跨越通道，由此容器内的过大的压力作用在凸缘（21）上，以将主体部分移动到打开位置，以便允许流体内容物通过其中，凸缘包括一个 或更多的孔。 此外，闭合阀包括可操作地连接到阀体部分（20）并被偏压以将主体部分（20）保持在通道关闭位置的一个或多个弹性元件（30）。
