Abstract
The invention relates to a container for a stack of interfolded tissue sheets. The container has a generally planar bottom wall and a top wall and side walls connecting the bottom wall with the top wall. An opening is provided in the top wall for the removal of the tissue-sheets from the container, which opening is wider than the width of the tissue-sheets. The stack of interfolded tissue-sheets is placed in the container with 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 a positioning feature having elongated, overlapping projections extending from opposite sides of the opening in order to allow the uppermost tissue-sheet to be dispensed, holding it substantially flat. The invention also relates to a method for producing the positioning feature.
