Definitions

  • the invention relates to a packaging made of a carrier material coated with a thermoplastic, such as e.g. Cardboard, for liquids or the like with a tubular main body with bottom and lid with gable fold, which has a pouring spout that can be opened by opening sealing seams, in the sealing area of which, in addition to sealing fields with strong adhesive force, those with low adhesive force are arranged for peeling apart the sealing fields, whereby Sealing field with low adhesive force is formed by a pattern of spaced-apart raised areas that alternate with adjacent and lower-lying fields.
  • a thermoplastic such as e.g. Cardboard
  • a pack of this type is known from GB-A-1,114,620.
  • This container with gable closure is about achieving a good seal without delamination problems when opening.
  • This is solved in the known case by providing a full cut through the material in a wall of the gable closure, above the gable surface and the adjacent triangular fields.
  • An outer zone with a roughened surface is arranged in a region between this continuous slot and a fold line adjoining the gable surface and the triangular fields.
  • This roughening can be achieved by abrasion, scratching, knurling or cutting.
  • the surface treated in this way allows the heat to flow away in the direction of neighboring non-roughened areas, because the roughening of the surface has the effect of a certain temperature insulation.
  • the object of the invention is therefore to improve the packaging of the type mentioned in such a way that one is neither dependent on sealing deterioration agents nor on complicated tools and also not on continuous cuts which endanger the material, in particular the opening of the packaging should be facilitated.
  • This object is achieved in that the area with low adhesive force extends into the gable surface and into the lateral triangular fields of the gable. Without a cut through the material and without damaging the plastic seal on the surface of the carrier material, these measures result in areas with weaker adhesive strength extending beyond the fold line mentioned and thus eliminating the risk that even outside the double cardboard strip, i.e. beyond the fold line, sealed with strong adhesive force and it is difficult to open, even if conventional sealing devices are used.
  • the raised areas are formed by periodically intersecting straight and / or curved ribs, the fields in between being lower or vice versa. Due to the multitude of ribs crossing each other and the fields lying between them, lying lower or higher, any gradation of adhesive force can be achieved in the sealing area in question, namely by controlling the number of ribs or their width, right down to the gable surface. Through the pattern of fields of different heights, a liquid-tight sealing of the pouring opening can be achieved, although the opening forces remain low in the desired areas. The simple method for preparing the relevant sealing fields can be seen.
  • the raised fields are a plurality of points and / or smaller areas arranged side by side, the circumference of which is angular and / or round.
  • the sealing field located on the pouring spout has a recess with low adhesive force. This avoids that after opening and reclosing the adhesion of the sealing surfaces pressed together during reclosing becomes too strong, so that the user has difficulties with the second and third opening. It has proven to be particularly expedient if, according to the invention, the recess is formed symmetrically to the tip of the pouring spout in the form of a bulge, because this makes it easier to produce the wall fields forming the pouring spout. A bulge is characterized in that a border line of the same is located on the outer edge.
  • Such a bulge can be created from a paper wall, for example, by cutting out a round piece on the outside edge with scissors; or a rectangular box; or cut out a jagged area that looks like a triangle.
  • the bulge is always open towards the edge. It is easier to manufacture, in particular if, in a further advantageous embodiment of the invention, the recess is triangular and the apex of this triangle forms the tip of the pouring spout. The hypotenuse opposite the apex could then, for example, be the cut off edge of this sealing field before the reduction. By reducing the sealing field with low adhesive force, its adhesive force is reduced even further in a very simple manner.
  • Another embodiment of the invention is further characterized in that fold lines are arranged in the sealing fields of low adhesive force which are attached to the two inclined surfaces forming the gable-shaped lid of the packaging and which preferably run vertically into the double cardboard strips. This creates a differently designed and easy-to-create pouring spout that is easy for the end user to open and use.
  • the invention depresses certain parts of the coated web in such a way that they do not participate in the welding or sealing process. This reduces the overall sealing area, and consequently the adhesive force of the sealing seam ultimately produced also decreases.
  • the packaging shown in perspective in FIGS. 1 to 3 is generally designated C. It has a tubular main body, generally designated 20, with a quadrangular cross-section, a base 21 and a gable-shaped lid, generally designated 22. This consists of two inclined surfaces 24, 25 and a double-layer cardboard strip, one layer of which is designated 29 and the opposite one is designated by 26.
  • the tubular main body 20 is closed along the sealing seam 38.
  • the folded gable surfaces 31 and 32 lying approximately perpendicular to the wall surfaces 24 and 25 are laterally connected to triangular fields 34, 35 and 36, 37, respectively, while fields 30, 41 and 42 are provided towards the opening side to form the ridge seam.
  • the entire packaging consists of paper or cardboard coated with thermoplastic on both sides, so that with a corresponding design of the sealing tools, a completely liquid-tight closing of the gable-shaped lid of the package is possible.
  • the pack After sealing, which takes place weaker over these areas 39, 40, 48 and 49 in such a way that these fields have a lower adhesive force and are consequently peelable, the pack can be brought into the position shown in FIG. 2 by a first step.
  • FIG. 8 In order to avoid possible re-adhesion of the sealing fields 48, 49, 39 and 40 of low adhesive force when the container is opened, the embodiment according to FIG. 8 is provided.
  • a prefabricated cardboard material i.e. 4 shows a broken-off blank according to FIG. 4, but with small changes, so that the packaging from the blank according to FIG. 8 represents a slightly modified embodiment compared to the packaging that is created from the blank of FIG.
  • Identical fields and parts of FIG. 8 for FIG. 4 are provided with the same reference numbers, but additionally have an apostrophe.
  • the sealing fields 39 ', 40' have been reduced, e.g. by cutting off a middle part 50, which is shown in FIG.
  • V-shaped section 50 preferably has the shape of an isosceles triangle, the apex 51 of which lies on the fold line 52.
  • the hypotenuse or base is approximately 25 mm and a corresponding triangle height is 4 to 5 mm.
  • the two wall panels 24 'and 25' arranged at the top of the packaging can also be provided with fold lines 55 and 56, some of which are arranged within corresponding sealing fields 48 'and 49' with a lower adhesive force.
  • These extra folding lines 55 and 56 preferably extend vertically upward in the illustration in FIG. 8 and represent extensions corresponding to the folding lines 57 and 58 within the wall panels 24 'and 25'. This forms a different and lighter pouring spout when the filled and sealed packaging C should be opened and their contents should be poured out.
  • the peelable sealing surface in the area of the special pattern 46 (for example rhombus-shaped depressions arranged at a distance from one another) can be opened in such a way that the two triangular fields 34 and 35 are pulled apart.
  • FIG. 3 shows the state after the pouring device has opened completely, namely the lip 45 of the pouring spout 44 serving as the pouring spout being folded out by loosening the pretreated sealing fields 47 and 49.
  • An embossing roller 1 is used to produce such a pattern.
  • a line of sealing fields 49 ', 40', 39 'and 48' arranged one behind the other is arranged on half the circumference of the embossing roller 1, ie over an area of somewhat more than 180 °.
  • Pattern fields 49 ', 40', 39 'and 48' arranged one behind the other and at least partially at a distance from one another, viewed from top to bottom.
  • the surface is shown, as shown in FIG. 7, the two raised pattern fields 39 'and 40', which are directly adjacent to one another without a distance, being approximately in the middle, to the right and left thereof the pattern fields 48 'and 49' are spaced apart. To the outside, further to the right and left, the remaining circumference of the embossing roll 1 has broken off, because there is no raised pattern field.
  • FIG. 9 The detail IX in Figure 7 is shown in Figure 9. Overall, this is the raised pattern field 40 ', in which raised fields 5 (this is the coherent main surface) alternate with lower-lying fields 6 in the form of rhombuses. At an angle of 60 ° to the axis of the embossing roller 1 there is a line of spaced-apart, periodically arranged rhombic depressions on the circumferential surface in such a way that the desired pattern results from the juxtaposition of a large number of such rhombic rows.
  • This pattern according to FIG. 9 can also be interpreted differently in that straight ribs intersect as raised surfaces 5 in such a way that the rhombic, lower-lying fields 6 remain between them.
  • FIG. 9 is created, for example, as a section of a sealing field with low adhesive force using a reverse tool, in which the rhombus-shaped surfaces 6 are raised and the crossing ribs 5 running next to these lie lower, a sealing field is obtained , as shown in FIG. 5 with 39, 40, 48, 49, in which the pattern to be thought of according to FIG. 9 alternates from the raised areas 6 with the adjacent and lower-lying fields 5.
