Abstract
A container for a stack of connected tissue-sheets has a generally planar top wall, a bottom wall and side walls connecting the bottom wall with the top wall and an opening provided in at least the top wall. The stack is 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, which is provided with elongated, overlapping projections extending from opposite sides thereof. Each projection has a tip terminating the projection before an edge of an opposing side of the opening, and the tips of adjacent projections extend past each other both in an inactive position, wherein all projections are placed in the same or in parallel planes, and in an active dispensing position, wherein the projections are turned upwards.
