Definitions

  • the invention relates to a cuboid flat gable composite package, in particular an ear package with a central or corner seam, the composite having at least one carrier layer made of paper or cardboard, an adhesion promoter layer, an oxygen barrier layer, preferably made of aluminum, and a plastic coating on both sides made of polyethylene (PE), with an im Packing gable provided opening area, which forms a pouring hole after severing, with a pouring element having a reclosable, hinged closure lid, the flange surrounding the opening area being firmly connected to the packaging surface and the closure lid having a tube corresponding to the contour of the opening area, in the region of the opening area the carrier layer is left out and a method for producing such a flat gable composite package.
  • PE polyethylene
  • Rectangular flat gable composite packages are known in many copies. They are mainly used in the field of liquid packaging in connection with cold, cold sterile, hot and aseptic filling. As a rule, these packages cannot be closed again after opening them once.
  • the flat gable composite package described above is in need of improvement in several points. It is clear that for the purposes of storage and transportation it must be ensured that the tube connected to the sealing cap must not penetrate the material prematurely, ie before the pack is used for the first time.
  • a tab is provided which fixes the closure cover and the flange of the pouring element which surrounds the dividing line at a predetermined distance. It is only after removing this tab that it is possible to push the opening tube into the composite packaging material by pressing in the sealing cover. This in turn means that a certain minimum height of the known pouring element is mandatory. However, this is disadvantageous because of the stackability required for flat gable composite packs.
  • the present invention is based on the object of a cuboid flat gable composite package of the type described in the introduction and a method for the same To design and refine production so that the overall height of the pouring element used is reduced and a perfect pouring is reliably guaranteed.
  • the solution to the problem is that an opening aid for pulling out the carrier layer-free composite piece located in the region of the opening surface is applied to the package gable in the interior of the sealed opening area.
  • both the flange of the pouring element surrounding the opening surface and the opening aid provided in the interior of the opening surface are sealed.
  • the pouring element and opening aid consist of a correspondingly sealable material, such as polypropylene.
  • the opening aid consists of tear-resistant, sealable and ultrasonically weldable material and is welded to the layer composite in the interior of the opening area. It is particularly expedient if the ultrasonic weld seam is essentially adapted to the contour of the opening of the pouring element. In this way, after removing such an opening aid, the composite piece located inside the opening is completely removed. It is clear that the opening aid should not protrude over the area of the opening of the pouring element so that the later application of the pouring element on the packaging surface is not impaired.
  • the geometry of the opening aid is selected so that the package is initially torn open at a single point of cracking. This can be done, for example, in that the circumferential sealing or ultrasonic weld seam has a discontinuity shaped as a tip or the like, from which the tearing process begins.
  • the opening area is produced by means of laser beams. Due to the good controllability of this technology and the absolutely clean cutting edge, laser production is the preferred method. Nevertheless, in an alternative embodiment of the invention it is also possible for the opening area to be produced by stamping.
  • the opening aid has a base plate and a handle provided on the base plate for lifting the base plate. It is particularly advantageous that the base plate is made of flexible material and that an annular tab is provided as a handle. In this way, the packing composite material present in the area of the opening area below the base plate can be removed by simply pulling it out together with the base plate and ring tab.
  • the overall height of the pouring element can be significantly reduced compared to the prior art, since a circumferential and a predetermined distance between the closure lid and the flange of the pouring element is no longer necessary. Furthermore, it is reliably excluded that the problems described above can occur during the pouring process, since the part of the “residual composite” which forms the opening surface never reaches the inside of the package from the pouring opening, but is removed to the outside before the first use. For easier opening, at least the upper PE layer is severed along the circumferential edge of the opening area.
  • FIG. 1 shows a block-shaped flat gable composite package 1 according to the invention in its entirety in a perspective view.
  • this is an ear pack with Center or corner seam.
  • a pouring element 2 which is firmly connected to the flat gable composite pack 1, can also be seen, with a flange 3, which is firmly connected to the pack surface 1A and which has a closure cover 4.
  • Under the pouring element is an opening area 5 which cannot be seen in FIG. 1.
  • FIG. 2 shows a section of an edge K of the opening area 5.
  • the edge K of the opening area 5 shows that it is produced by means of laser beam cutting.
  • the individual layers of FIGS. 2, 3A and 3B are not designated in more detail, but are reproduced from top to bottom (outside inwards): PE layer, paper or cardboard layer, adhesion promoter layer, oxygen barrier layer, PE layer.
  • an opening aid 6 is now applied to the packing gable inside the opening surface 5, as can be seen in particular in FIG. 4.
  • the opening aid 6 has a base plate 7 and a handle 8 provided on the base plate 7 for lifting the base plate 7.
  • the handle 8 is designed as a ring plate.
  • FIGS. 5 to 7 show an embodiment of a pouring element according to the invention in the closed state.
  • the closure cover 4 is articulated on the vertical part of the flange 3 surrounding the dividing line. Furthermore, the closure cover 4 has a tube 9 corresponding to the shape of the opening surface 5, as can also be seen in FIGS. 4, 6 and 7.
  • Fig. 3b can also be seen that an opening aid, not shown, can also be arranged within the opening surface 5, which consists of tear-resistant, sealable and ultrasonically weldable material and is ultrasonically welded to the outer PE layer of the pack.
  • an ultrasonic weld seam is indicated by a dash-dot line.
  • the circumferential ultrasonic weld seam has a discontinuity, namely a tip S serving as a tearing point, which reaches up to the edge of the opening surface 5. In this way, it is reliably ensured that when the opening aid (not shown) is actuated, the opening area 5 is first torn open in the region of the tip S. From there, tearing on both sides takes place along the opening contour, in particular if - as indicated in FIGS. 3b and 2 - the upper PE layer has been separated along the opening contour by means of a laser beam L.
  • the opening aid 6 can consist of a piece of film, the external dimensions of which do not protrude beyond the contour of the opening area, in order not to impair the later application of the pouring element 2.
  • the closure cover 4 is raised and thus brought into the position of FIGS. 6 and 7. Subsequently, the opening aid 6 is raised by tearing the lower layers together with the handle 8 fastened to the base plate 7 together with the composite remnant formed by the opening surface 5 until a completely exposed pouring hole 10 is formed, as shown in FIG. 7.
  • the tube 9 can be anchored in the interior of the circumferential flange 3 by closing the closure cap 4 again.
  • a projection 11 is provided at the tip of the closure lid 4, which protrusion forms the pouring spout 12 formed by the pouring element 2 at least on the side opposite to the articulation, as can be seen in particular in FIG. 5.
  • the outer PE layer in the region of the edges of the opening area is destroyed, for example by laser radiation.
  • the opening area 5 still has four layers, but the circumferential dividing line only consists of an oxygen barrier layer and an inner PE layer.
