Abstract
A container for a stack of interfolded tissue-sheets has a generally planar top wall, a bottom wall, side walls and an opening provided in the top wall for the removal of tissue-sheets from the container. The opening is provided with elements for presenting the tissue, preferably in the form of elongated projections, extending in-between each other from opposite sides of the opening in a first, inactive position. Adjacent projections are spaced apart both in the first, inactive position, in which the projections are substantially in the same plane as the top wall, and in a second, active position, in which the projections are raised and impart a primary wave-shape to a tissue sheet in a presentation position. The opening has a main axis with a predetermined curvature, which opening imparts a secondary wave-shape to the tissue sheet in the presentation position when the projections are in the second, active position.
