The invention relates to a container for a collection of interfolded or mechanically connected tissue-sheets, the container having a generally planar bottom wall and a top wall and a pair of side walls and a par of end walls connecting the bottom wall with the top wall and an opening provided in at least the top wall for the removal of the tissue-sheets from the container, the stack of interfolded tissue-sheets being placed in the container with at least a pair of edges of a lowermost tissue-sheet placed on the bottom wall and an uppermost tissue-sheet placed near or in contact with the top wall and adjacent to the opening in the top wall. The opening is provided with elongated projections extending from opposite sides of the opening, wherein each projection in an initial position extends across the opening in the plane of the top wall and is positioned adjoining at least one opposing projection, and the projections are arranged in co-operating pairs, wherein each projection has at least one inner section having a smaller width than an adjacent outer section.
