摘要
The present invention relates to a container assembly for accommodating a beverage. The container assembly comprises a collapsible beverage container having a body part for accommodating the beverage and a cylindrical neck part defining a gas-filled headspace. The container assembly further comprises a closure sealing off an opening of the cylindrical neck part. The closure comprises a closure disc, an inner cylindrical part and an outer cylindrical part. The closure disc comprises a beverage outlet for extracting the beverage. The closure further comprises a pressure-relief device located at the closure disc or the inner cylindrical part. The pressure-relief device is capable of establishing a permanent or reclosable opening through the closure or between the closure and the neck part for allowing a flow of fluid from the headspace to an external space when a pressure difference exceeds a predetermined pressure value being lower than the burst pressure of the container.
