Definitions

  • the invention relates to toilet paper, as is usually provided as a wound toilet paper roll in toilet rooms.
  • toilet paper is made available to the consumer on a roll.
  • a piece of toilet paper is endlessly wound on a piece of cardboard tube, the length of which corresponds to the width of the toilet paper roll.
  • perforation lines which run across the strip and are at a constant distance from one another.
  • pieces of toilet paper of the same size can be torn off the roll one after the other. It is also possible to tear two or three contiguous pieces of paper off the roll and then fold the torn piece in its perforation lines. In this way, the consumer can create a multi-layer and thus any thick piece of toilet paper.
  • Toilet paper rolls are known whose pieces of toilet paper have a width of approximately 10 cm (centimeters) and a length of approximately 14 cm. The perforation lines are spaced about 14 cm apart.
  • toilet paper rolls are also known whose pieces of toilet paper have a longer length in comparison with the same width. The users accept the size of the toilet paper pieces as a given. The material thickness of the individual pieces is often judged to be too low and the papers are therefore used in two or more layers.
  • the object of the invention is to provide the consumer with pieces of toilet paper that are as large as possible.
  • the invention is based on the knowledge that the area of a piece of toilet paper that is effectively used in each case is regularly smaller than its actual area.
  • the lines of weakness are arranged on a toilet paper strip wound into a roll in such a way that the individual pieces of paper are not larger than approximately 100 to 120 cm 2 (square centimeters).
  • a second solution according to the invention includes that weakening lines are present at an angle deviating from 90 degrees (old degrees), based on the rolling direction.
  • a stack of toilet paper can thus be formed, the base area of which is created by folding in the lines of weakness * is larger than the area of the individual piece of toilet paper.
  • the desired one is nevertheless and only the required multilayer is present, while the multilayer decreases in a practically non-disturbing manner in the direction of the stack edge. Therefore, the benefit resulting from a multi-ply toilet paper stack with the large base area known in the prior art can also be achieved with comparatively smaller toilet paper pieces.
  • pieces of toilet paper which have the large areas known in the prior art can also be used to produce even larger pieces of toilet paper.
  • the areal size of the respective pieces of toilet paper, which are also stacked one above the other, is defined by the coherent paper surface, which is not disturbed by holes passing through the paper stack.
  • Toilet paper strips wound on a roll can have several different lines of weakness.
  • the weakening lines can be present alternately, at an angle of 90 degrees and at an angle different therefrom, in each case with respect to the rolling direction.
  • the individual pieces of toilet paper, each separated by lines of weakness then have, for example, the shape of a one-sided or a two-sided trapezoid.
  • Pieces of toilet paper in the form of a parallelogram can be produced by lines of weakness, which are arranged parallel to each other and which have an angle deviating from 90 degrees to the rolling direction.
  • lines of weakness which are arranged parallel to each other and which have an angle deviating from 90 degrees to the rolling direction.
  • the pieces of paper also shown in an exemplary embodiment have the shape of a square. It has been found to be completely sufficient if the length of the square side corresponds to the smaller side of the pieces of toilet paper known in the prior art, that is, for example, approximately 10 cm in size.
  • the pieces of toilet paper can have the shape of a trapezoid. Because the trapezoidal pieces are also used in the direction of the diagonal of the trapezoid. can, it has turned out to be sufficient if only the larger of the two parallel edges of the respective individual piece of paper is about 10 cm in size. The smaller, parallel edge of the piece of paper only needs to be about 6 to 7 cm in size.
  • the trapeze can be regular or even one-sided
  • Such trapezoidal pieces of toilet paper can either be wound on a toilet paper roll so that the width of the toilet paper roll corresponds to the height of the individual trapezoids, or in such a way that the maximum width of the toilet paper roll corresponds to the length of the larger of the two base areas of the trapezoid. in the the latter case, the side surface of the toilet paper roll ⁇ is not flat.
  • two strips of toilet paper can be wound side by side on a roll of toilet paper.
  • This toilet paper roll then has a correspondingly greater width and the tube on which the two strips are wound has a correspondingly greater length.
  • the two strips can consist of two wound-up toilet paper strips of the type described above, which are laterally connected by a common line of weakness, such as a perforation line. From such an enlarged toilet paper roll compared to the prior art, the users can tear off individual or even several connected pieces of paper at will and then use correspondingly single-layer or multi-layer toilet paper pieces that are smaller or larger in plan.
