Abstract: A vented keg closure (1) for use with a keg (30) that contains a fermenting beverage is described. The closure (1) comprising a filter member (41) disposed within an airway of the closure (1) that communicates between an internal headspace (36) of the keg (30) and an environment external to the keg (30). The closure (1) has a first configuration wherein the filter member (41) is located at a first position at which it filters gas flowing through the airway. The closure (1) also has a second configuration wherein the filter member (41) is located at a second position at which gas flow through the airway can be increased by at least partially bypassing the filter (41). The extent of movement between the first and second configurations is controlled by the gas pressure difference across the airway.

Abstract translation: 描述了与含有发酵饮料的小桶（30）一起使用的通风小桶封闭物（1）。 所述封闭件（1）包括设置在所述封闭件（1）的气道内的过滤构件（41），其在所述小桶（30）的内​​部顶部空间（36）和所述小桶（30）外部的环境之间连通。 封闭件（1）具有第一构造，其中过滤构件（41）位于第一位置，在该第一位置，其过滤通过气道的气体。 封闭件（1）还具有第二构造，其中过滤构件（41）位于通过至少部分地绕过过滤器（41）的情况下能够增加通过气道的气体流动的第二位置。 第一和第二构型之间的运动程度由气道上的气压差来控制。
