Definitions

  • the invention relates to a folding box pack made of a liquid-tight, at least internally heat-sealable coated cardboard composite material, in particular Al-laminated cardboard composite material, with an integrally folded flat bottom, which is closed by at least one flat seam, in particular a seam, and two pairs of opposed flat and full-surface sealed triangular folding pockets.
  • Folding box packs of this type with differently shaped bottoms are known (DE-C-25 20 401; EP-A-0 093 849; EP-B-0 133 863). These folding boxes are made from a blank or from a roller conveyor or from a jacket, with the floor being heat-sealed by means of ultrasound, induction, heat pulses, infrared radiation or hot air. If such folding box packs are intended for the aseptic packaging of goods, it is customary to apply a full surface area of liquid or vapor sterilizing medium to them before filling. This sterilizing medium must then be completely removed from the package. In order for this to be possible, the triangular folding pockets must be sealed over the entire surface to avoid nests in the pack. This sealing can best be achieved with IR radiation or hot air. The areas to be sealed with each other must be because of the well over 100 ° C lying melting point of the heat sealable coating with hot air of well over 100 ° C.
  • a relatively high activation temperature at which bubbles do not yet form, can be used if the Keep activation temperature within narrow tolerances. Adhering to such tolerances means an increased effort in production.
  • the invention has for its object to provide a folding box pack of the type mentioned, in which there is no blistering of the inside of the cardboard material when the bottom is activated with heat even if the activation with a higher temperature than for the heat seal is essential required.
  • the invention is based on the knowledge that the formation of bubbles is due to moisture present in the cardboard composite material, which increases the vapor pressure in the cardboard material in particular at an activation temperature that is well above 100 ° C. in such a way that with a dense outer coating, as is the case, for example, with the purpose of Better printability on the outside with a cardboard box equipped with a line or, in the case of a cardboard coated on both sides, water vapor escapes to the inside of the composite and leads to the formation of bubbles and leaks.
  • the inner fields are particularly affected by this formation of bubbles, i.e. the large areas to be activated that are not are directly delimited by a cutting edge, while in the case of outer fields, i.e.
  • the areas to be activated which are located directly on a cutting edge, they are significantly smaller and do not occur in the case of correspondingly narrow outer fields running parallel to the cutting edge and adjacent to it, since in These outer fields allow the steam to escape through the open cut edges.
  • a vapor pressure cannot generally build up because the water vapor which forms when the fields are activated with heat can escape to the outside via the perforation which is initially still exposed.
  • the activation temperature is not critical, which means that it is not important to keep the temperature within narrow limits. Experiments have shown that there is no blistering on the inside of the cardboard composite material even if the activation temperature even exceeds the current activation temperature of, for example, 160 ° C. by more than 15 ° C.
  • the perforation on the finished package does not interfere with its use, since it can be chosen so that it is folded in and sealed in, so that it is protected from dirt and, through it, no moisture can penetrate into the composite material.
  • the cardboard composite material comprises coated cardboard and / or the inner or outer coating has little adhesion to the cardboard, it may be advantageous to perforate the outside of the composite material in the area of the fields to be sealed as far as the cardboard, to prevent blistering on the outside.
  • the rectangular blank for a cuboid folding box pack shown in the drawing FIGS. 1a to 1e consists of a cardboard composite material that is laminated on the inside of the packaging with an aluminum foil and has a heat-sealable plastic coating (PE) on the inside and outside.
  • PE heat-sealable plastic coating
  • the blank is provided with folding lines 1, as shown in the drawing.
  • the heat-sealable coating and the aluminum foil are perforated on the inside, at least in the inner fields 2 hatched in FIG. 1a for the formation of the triangular folding pockets 3, but preferably also in the hatched outer fields 4 for the web seam 5 in FIG. 1b.
  • the composite material is also perforated from the outside in the inner fields 2 shown hatched in FIG. 1c and in the outer fields 4 shown hatched in FIG. 1d. From FIG. 1e the floor area of blanks with the inner and outer fields 2, 4 to be activated on both sides for the floor sealing, precedes this.
  • FIGS. 2a to 2e and 3a to 3e show different, different embodiments of blanks for folding box packs with a field division corresponding to FIG. 1.
  • FIGS. 4 to 7 show the bottom area of the different blanks in the individual manufacturing steps.
  • FIGS. 4 and 5 correspond to the cut according to FIG. 1
  • FIG. 6 corresponds to the cut according to FIG. 2
  • FIG. 7 corresponds to the cut according to FIG. 3.
  • the blank prepared in this way is first formed into a tube with a rectangular cross section, as shown in FIGS. 4f, 5f, 6f and 7f, which show the bottom area in the activation position. Then the hatched fields of the bottom in FIGS. 1 to 3 are activated and the bottom is formed by folding in the direction of the arrows from FIGS. 4f, 5f, 6f and 7f.
  • the triangular folding pockets are formed, as can be seen from FIGS. 4g, 5g and 7g, and the hatched areas are folded in the bottom of the pack and sealed, if necessary, so flat that they are covered towards the inside and outside of the pack.
  • Figure 4h shows the finished bottom of a blank according to Figure 1a to 1e, Figure 4h 'the finished bottom of a blank according to Figure 1b or 1d, Figures 5h and 5h' the finished bottom of a blank according to Figure 1b, Figure 6h the finished bottom of a blank according to FIGS. 2a to 2e and FIG. 7h the finished base of a blank according to FIGS. 3a to 3e.
  • the triangular folding pockets 3 are folded out laterally and in FIG. 5h 'on the package bottom.
