Definitions

  • the invention relates to a packaging box as a storage container for a film web with a tear-off edge arranged in a side wall of the box for severing the film web which can be guided over this by pulling on the free film end.
  • a packaging box of this type is disclosed by GB-PS 1 282 045; the cuboid, elongated cardboard packaging box is intended to hold rolled metal foils, which can be separated in the area of a corrugated tear-off edge.
  • This slightly corrugated tear-off edge runs as a straight tear zone in the middle of a side wall of the packaging box.
  • tear-off edges are sufficiently effective with metal foils, which also applies to so-called corundum strips of DE-OS 29 27 195.
  • the inventor has set the goal of equipping a packaging box of the type mentioned at the outset with a tear-off edge in such a way that even high-stretch films can be used in sections in the usual way.
  • the tear-off edge is designed as a tooth edge curved in the pulling direction. This curvature allows the areas near the edges of the film to come into contact with only a few teeth, so that only a small area of the film has to be applied with the entire tensile force; if the outer teeth are in contact with the film, this only comes into contact with other teeth in the central area.
  • the tooth edge has at least two g e-curved ridge lines running at a distance from one another as geometric locations for tooth tips, ie that at least two curved so-called attack zones are formed, which are formed by those tooth tips.
  • center lines of the triangular teeth run parallel to the direction of pull; it would be obvious to arrange those center lines perpendicular to the ridge lines, but this would lead to undesired component directions. It has been shown that the direction of the center lines of the triangular teeth described above offers optimal tear-off conditions.
  • the two - or more - ridge lines determine larger and shorter teeth which, according to a further feature of the invention, are arranged in alternation with one another, it having proven particularly advantageous to arrange the tips of these teeth in such a way that the film is in the pulling direction first hits the tip of a large tooth, then the tip of the adjacent large tooth and only then touches the tip of the small tooth in between. This considerably increases the mode of operation of the packaging box according to the invention for the purpose seen by the inventor.
  • the distance between the crease line delimiting the side wall on the one hand and the base line delimiting the tooth edge in the pulling direction on the other hand is smaller at its apex than half the height of the side wall; this eliminates the deflection of the central wall area at the tear-off edge, which is known from other packaging boxes and occurs when the train is pulled. As is well known, this temporary deformation often leads to tearing of the side wall from the tear-off edge.
  • this defines a straight ridge line up to the center of the side wall or beyond which is inclined to the direction of pull. It is also possible to have a straight tooth edge section inclined in this way merge into a curved part, for example near the center of the side wall.
  • the side wall containing the tear-off edge of which is assigned a cutting strip which is designed to be divisible by at least one predetermined tear line into a cover flap and a pulling strip, this pulling strip before the packaging box is put into use, i.e. before first access to the transparent film on which the packaging box, in particular on that side wall, is fixed.
  • This pull strip is separated by a short tensile stress and then releases the cover flap, which is inserted into the interior of the box for use in the manner already described and then forms a through-slot for the transparent film with the side wall containing the tear-off edge.
  • the cover flap can also be fixed to the packaging box in a manner other than that described; of importance to the invention remains that it is shorter than the side wall containing the tear-off edge, so that it can be placed under pressure on the cover strip of the packaging box, at least at maximum diameter, of a film roll formed by the transparent film.
  • a permanent adhesive layer is assigned to the free lower edge of the short cover flap, which adheres briefly to the transparent film when the cover flap is pressed down and raises it thanks to the restoring forces in the cover strip when it is reshaped so that a user can grip the transparent film and can bring in tear-off position.
  • the user therefore presses the lid strip of the packaging box down towards the inside of the box and releases it again briefly in order to achieve the lifting effect described.
  • he Once he has grasped the free end of the film, he pushes the cover strip downwards again and creates an abutment with the free lower edge of the cover flap, which greatly facilitates the tear-off of the high-stretch transparent film.
  • the blank for producing the packaging box can have one or more of the features which are described in the above description and in the claims for the packaging box itself.
  • the cut for a cuboid cardboard box 1 - or a box made of a corresponding material - for receiving a high-stretch transparent film 3 wound on a cardboard tube core 2 consists according to FIG Longitudinal edges 7, adjacent side walls 8, 9.
  • the two side walls 8, 9 are provided with buckles 11 along their top edges 10, which are formed by fold lines like the top edges 5.
  • the one side wall 9 is separated from a cover strip 12 and this from an attached cover flap 13 by a crease line 14 and 15, respectively.
  • the blanking strips 8, 4, 9, 12 are generally of the same height h; the length of the cover flap 13 or of its free flap edge 16 is slightly shorter in FIG. 1 by a dimension 2 ⁇ n than the length i of the cut strips 8, 4, 9, 12, that recess dimension n is between the side edges 17, 18 of Cover strip 12 and cover flap 13 can be seen.
  • the side wall 8 lying above in FIG. 1 reveals a toothed rim 20 which is part-circular around a center point M located on the center line M - and outside the drawing sheet - which starts at both ends from the longitudinal edge 19 of the side wall 8 and its base line S in that cutting line M has its apex Z; its distance e from the adjacent longitudinal edge 7 forming a crease line is, for example, one third of the strip height h.
  • the tooth edge 20, which is enlarged and shown schematically in FIG. 2, is delimited towards the side wall 8 by that base line S.
  • a first ridge line K 1 runs at a radial distance a therefrom, to which a second ridge line K 2 can be seen in the radial distance b; these radial distances a, b are approximately the same length, the radii of the curved lines S, K 1 and K 2 in Fig. 1.5 indicated by r s , r 1 and r 2 .
  • the first ridge line K 1 is the geometrical location of the tips 21 of short teeth 22 of the tooth edge 20. The latter alternate with larger teeth 24, the tips 23 of which determine the ridge line K 2 .
  • the tips 23 of the large teeth 24 belong to small triangles 25, one of which is in the right half 2 is hatched.
  • the side edges 26 of the triangle 25 enclose an angle w of 40 0 and extend to a line 27 which q runs from the top 23 and determine from the starting side edge portions 26 a has an opposite w greater included angle w 1 of 60 ° at a distance .
  • the inclusion angle t of the short teeth 22 is 50 °.
  • the distances f lying horizontally in FIG. 2 between the tips 21, 23 of adjacent teeth 22, 24 are slightly larger than the double distance q at the triangle 25 in the selected exemplary embodiment.
  • the distance g between two tips 23 of large teeth 24 obviously corresponds to twice the distance f.
  • the center lines N of the large teeth 24 and the center lines Q of the short teeth 22 run parallel to one another and are i. w. perpendicular to the longitudinal edges 7 and thus in the pulling direction x for the transparent film 3 of high elasticity.
  • a fold line 40 is created between the two outer teeth 24 in the drawing, in the direction of the train x the transparent film 3 is first scored by the outer teeth 24 e and then - in each case on both sides of the line of symmetry M - touches the following tooth 24 and then the outermost tooth 23 of the ridge line K 1 , which lies between the first two teeth 24 of the ridge line K 2 lies.
  • the transparent film 3 is perforated in steps from the film edges 41 to the inside.
  • the transparent film 3 is completely severed when the tooth 24 assigned to the vertex Z has started to operate. It is clear that the position of the center lines N, Q described in the pulling direction x which is essential for the tearing process has a considerable influence on the separating action.
  • Fig. 4 illustrates an embodiment with a straight ridge line R, which - with the line 40 following the course of the omitted longitudinal edge of the side wall 8 - includes an angle of inclination y of approximately 12 °.
  • the tip areas determined by the triangles 25 are additionally impregnated with a hardener.
  • a cut strip 33 is connected to the cover strip 12, which is provided with a predetermined tear line 34 at a distance c (e.g. 1/3 h) from the flap edge 16. This ends at gusset-like edge incisions 35 and divides the blanking strip 33 into a cover flap 13, which is narrower than in FIG. 1, and a pulling strip 36 of precisely that width c.
  • the predetermined tear line 34 rectangular multilayer flap 44 glued from a double-sided adhesive strip 45 and a protective strip 46 covering it.
  • the double-sided adhesive strip 45 has a separating cut 47 above the predetermined tear line 34, so that when pulling on the tapering grip end 37 of the pull strip 36 which is tacked onto the side wall 8 and can thus be detached therefrom, the predetermined tear line 34 is severed and with the pull strip 36 that of the separating line 47 limited section 45 a of the double-sided adhesive strip 45 including protective strip 46 is lifted off (FIG. 8). A narrow, slightly adhesive adhesive strip then remains on the cover flap 13 for 45 hours .
  • the cover strip 12 can be pressed onto the film wrap 3 w by the indicated finger of a user - or the bottom edge 34 of the flap 34 i placed on the box bottom 4 - and then on Adhesive strips 45 h hanging transparent film 3 are lifted into the pulling position shown in FIG. 10. This is particularly advantageous when the pulling end 39 of the transparent film 3 has crept into the cardboard box 31 after a long period of rest.
  • the cover strip 12 has returned to the pulling position according to FIG. 10 after the described capturing of the transparent film 3 and its release, the user can grip the pulling end 39 and place it around the tooth edge 20 in the manner already discussed. Then the cover strip 12 is again by the user's finger in the tear-off position according to Fig.1 transferred; there is a certain tension between the tooth edge 20 and the lower edge 34 i of the cover flap 13 i , which favors the tearing process. The adhesion of the transparent film 3 to the adhesive strip 45 h is not so great that this could be a hindrance during the tear-off process.
  • the adhesive strip has remained 45 h in total on the cover flap 13 i , which in the vicinity of that adhesive strip 45 h has a strip-like formation 50 which the lower edge 34 i offers.
  • the pull strip 36 already removed in FIG. 9 is designed accordingly.
