Abstract

A portion pack for producing a beverage includes a container made of filter material in which an extraction material is arranged. The container has an upper side and a pivotable edge portion that is initially arranged in a closed position to close the upper side of the container. A supporting body encloses at least regions of the container. The container is held closed by a closure mechanism which is adapted to be releasable by moistening the supporting body with water to cause the pivotable edge portion to pivot upwardly to a beverage preparation position in which the upper side of the container is open. The invention also relates to a method for producing a beverage using such a portion pack.
