  • Patent number: 5121879
    Abstract: Folded paper tissues are generally packed in thin foil or film. The pack is provided with a tear-open aid having a tear-open flap (27) limited by perforation lines and an adhesive tape (33) partially covering the tear-open flap. For reasons of better handling and economical production of the pack, the tear-open flap (27) is connected to form a unit with part of the end wall (14), namely with an outer longitudinal flap (25) of the same or an adjoining flap (42) or extension (43) formed by the end wall, which can be moved with the aid of the adhesive tape into opening and closing position. In connection with the folding of the end wall (14), the design of the tear-open aid creates an advantageous extraction opening (37) by means of the given width of an inner longitudinal flap (26).
