<p>The cardboard container for a stack of paper sheets is designed to hold the sheets ready for extraction and incorporating corner stops arranged so that they can be extracted one at a time. The container is made from a flat blank, and when erected contains a spring having a suitable large diameter, supporting a thick sheet carrying the stack, holding it against the corner stops. These stops are formed by two projecting triangular tabs (11a,11b) which are folded over and secured by adhesive. They project upwards from two adjacent panels (3,4) of the blank, and two stops can be incorporated in diagonally opposite corners, retaining the sheets, but leaving two remaining free for extraction. The spring is also supported by a thick sheet at the base.</p> |
