Definitions

  • the invention relates to a tube made of cardboard according to the preamble of claim 1.
  • Such packaging is indeed well suited for transporting and pouring bulk materials, such as powdery materials on the one hand and liquids on the other.
  • bulk materials such as powdery materials on the one hand and liquids on the other.
  • the material to be stored in the packaging has a high viscosity or is even creamy or pasty-like, the problem with the packaging described at the outset is that the material cannot be emptied well from the packaging.
  • EP-A-0 172 711 a package is known in which an outer container with an inner container provided therein can be compressed to expel the contents of the container.
  • the rear wall is only connected to two side walls, while at least one side wall has no connection to the rear wall, the two side walls connected to the rear wall can be printed together.
  • the side wall not connected to the rear wall can move outwards. Therefore, the entire packaging can be compressed. This means that cream and paste-like substances can also be pressed out of the packaging.
  • the cardboard tube has an outer carton 2 and an inner bag 3.
  • the carton 2 is formed from the blank 4 shown in FIG. 1.
  • the blank 4 has a first side wall 5 and a second side wall 6.
  • a third side wall is provided between the first side wall 5 and the second side wall 6.
  • a fourth side wall 8 is provided on the side of the first side wall 5 facing away from the third side wall 7.
  • a rear wall 9 is provided on the rear side of the first side wall 5 (the lower side in FIG. 1).
  • the rear wall 9 extends essentially over the full width of the first side wall 5.
  • the height of the rear wall 9, i.e. the extent with which the rear wall 9 extends away from the first side wall 5 is somewhat larger than the width of the third side wall 7 or the fourth side wall 8.
  • An adhesive strip 10 is provided on the lower side of the second side wall 6.
  • An adhesive strip 11 is provided on the side of the fourth side wall 8 facing away from the first side wall 5.
  • a first cover plate 12 is provided on the front of the first side wall 5 (the upper side in FIG. 1).
  • the cover plate 12 extends essentially over the entire width of the first side wall 5.
  • the height of the first cover plate 12 corresponds essentially to the width of the third side wall 7 or the fourth side wall 8.
  • an adhesive tab 13 is provided on the side of the cover plate 12 facing away from the first side wall 5 .
  • Two triangular adhesive tabs 14 and 15 are provided on both sides of the cover plate 12.
  • a second cover plate 16 is provided on the front of the second side wall 6.
  • the second cover plate 16 extends essentially over the full width of the second side wall 6. Its height corresponds essentially to the width of the third side wall 7 or the fourth side wall 8.
  • the rear wall 9 has a crease line 17.
  • the kink line 17 extends essentially parallel to the underside of the first side wall 5. It runs essentially half the distance of the height of the rear wall 9 from the underside of the second side wall 5.
  • the 1st - 4th side walls 5-8 have a crease line 18, 19, 20 and 21 respectively.
  • the crease lines 18-21 are substantially parallel to the front of their respective side walls. The distance from the front sides is approximately half the width of the third side wall 7 or fourth side wall 8.
  • a line of weakness 22 is attached in the third side wall 7.
  • the line of weakness extends from the rear to the crease line 20.
  • the line of weakness 22 extends substantially parallel to the side edges and at substantially equal distances from the right and left side edges.
  • a corresponding line of weakness 23 is provided in the fourth side wall 8.
  • the weakening line 23 also extends essentially from the rear side to the crease line 21. It is essentially parallel to the side edges and at the same distance from both side edges.
  • a further weakening line 24 is provided in the third side wall 7.
  • the weakening line 24 extends from the point at which the weakening line 22 meets the fold line 20 to the front connection point between the first side wall 5 and the third side wall 7.
  • a corresponding weakening line 25 is provided in the fourth side wall 8. It extends from the point at which the weakening line 23 abuts the kink line 21 to the front connection point between the first side wall 5 and the fourth side wall 8.
  • the weakening lines 24 and 25 form a straight line as weakening lines 26 and 27 in the first cover plate 12 continues. They extend essentially to the middle of the cover plate 12.
  • Lines of weakness 28 and 29 are also provided in the second cover plate 16.
  • the weakening lines 28 and 29 are arranged mirror-symmetrically to the weakening lines 26 and 27, i.e. they therefore extend from the upper corners of the cover plate 16 to substantially the middle of the cover plate 16.
  • the third side wall 7 has a crease line 30.
  • the fold line 30 extends from the point at which the weakening line 22 abuts the fold line 20 to the front connection point between the third side wall 7 and the second side wall 6. It is therefore symmetrical to the weakening line 24.
  • the fourth side wall 8 has a crease line 31.
  • the crease line 31 extends from the point at which the weakening line 23 meets the crease line 21 to the front connection point between the fourth side wall 8 and the adhesive strip 11.
  • the crease line 31 is therefore symmetrical to the weakening line 25.
  • the tube is made as follows: A blank as shown in FIG. 1 is folded and closed around the connecting lines between the side walls and the adhesive strip 11 to form a sleeve by the adhesive strip 11 being glued to the second side wall 6 at its free side edge. A foil bag is put over a mandrel. The box sleeve is placed over this. Thereupon the second cover plate 16 is first folded over by essentially 90 degrees and then the first cover plate 12 is folded over by essentially 90 degrees and glued to the second cover plate 16. The adhesive flap 13, the adhesive flap 14 and the adhesive flap 15 are then folded over in this order by essentially 90 degrees and with the second side wall 6, the third side wall 7 or the fourth side wall 8 glued.
  • a punching tool is guided through the mandrel, with which a hole is punched through the bag film and the cover plates 12 and 16.
  • a pouring spout 32 is inserted into this hole from the outside and is reshaped on the inside by means of a shaping stamp and firmly connected to the bag and the folding box.
  • the tube prepared in this way is pulled from the mandrel and passed through the still open bottom, which forms the back, for filling.
  • the bottom closure begins with the spreading and sealing of the protruding bag film of the inner bag.
  • the resulting film tips are folded inwards by about 180 degrees.
  • the rear wall 9 is folded inwards and glued to the adhesive flap 10 such that the rear wall 9 has a curvature of approximately 10 degrees inwards along the fold line 17. This can be carried out particularly suitably, since the height of the rear wall 9 is somewhat larger than the width of the side walls 7 and 8.
  • the tube is used in the following way: After the filled tube is placed on the market, the consumer removes a closure provided on the pouring spout and presses the tube packaging together from the rear on the two side walls 5 and 6. Then the rear wall 9 bulges into the carton. The inner bag therefore always remains secured in the box.
  • the third and fourth side walls 7 and 8 are bent outwards along the weakening lines 22 and 23.
  • the transition to the front wall, which is formed by the first and second cover plates 12 and 16 takes place along the weakening lines 24 and 25 or along the kink lines 30 and 31.
  • the tube can be compressed completely until the two Side walls 5 and 6 lie parallel to each other, only separated by the empty inner bag.
  • FIG. 3 an intermediate stage of tearing is shown, in which the two cover plates 12 and 16 are open. Furthermore, the carton on the weakening lines 22, 23; 24, 25; 26, 27; 28, 29 are separated and the inner bag can be easily removed. The cardboard box made of a highly recyclable material and a light inner bag are then available, both of which can be disposed of easily.
  • both the rear wall (9) and the cover plates 12 and 16 are formed in a rectangular shape.
  • these elements can also be designed in a triangular shape. Then two of the three side walls are connected to the rear wall, while the third side wall is not connected to the rear wall. When the two side walls connected to the rear wall are pressed together, the third side wall is bent outwards.
  • a hexagonal design of the rear wall and the two cover plates can also be carried out well. Again, two opposite side walls are connected to the rear wall. The other four side walls are not connected to the rear wall. When the two side walls connected to the rear wall are pressed together, the other four side walls automatically turn outwards. It does not even require the weakening lines 22 and 23 in the embodiment mentioned at the beginning.

Abstract

Il est souvent difficile de vider les boîtes pliantes usuelles d'emballage lorsque les produits que l'on veut en retirer sont visqueux, crémeux ou pâteux. L'invention propose par conséquent de pourvoir un carton extérieur (2) d'un sac intérieur (3) susceptible d'être vidé au moyen d'un bec verseur (32). La paroi du fond (9) opposée au bec verseur n'est reliée qu'à deux parois latérales. On peut ainsi presser ensemble ces deux parois latérales, de manière à faire plier la paroi de fond vers l'intérieur et les autres parois latérales vers l'extérieur, ce qui permet d'exprimer de la boîte même des matériaux crémeux ou pâteux.
