Definitions

  • foil packaging in particular foil bags
  • the present invention relates to a foil packaging, in particular foil pouches, having a cap closure arranged on the top side, comprising a pouring tube, and optionally a standing floor.
  • tubular bag of this type are well known. They are mainly used to absorb liquid or flowable products such as liquid soap or hair shampoo or the like. They are comfortable and practical to handle. After opening the cap closure, the products can be squeezed out of the packaging by simply pressing on the packaging.
  • tubular film bags according to DE 202 12 251 U1 and "EP 1 362 797 A2, each of which is based on the Applicant.
  • the spout tube comprises a relatively solid connecting element having a triangular cross section, i. a cross section formed by two symmetrically oppositely directed circular arcs.
  • the circular arc walls serve to seal the packaging film.
  • the circular arc walls extend parallel to the longitudinal axis of the Ausgußrschreibchens.
  • the present invention is therefore an object of the invention to provide a film packaging, in particular a foil bag, which is characterized by a substantially wrinkle-free, bulbous transition between the bag body and cap closure on the one hand and a material-saving closure construction on the other.
  • the Ausgußrschreib- chen has a funnel-shaped or cone-shaped portion to which the packaging film is ansiegelbar.
  • the funnel-shaped or cone-shaped sealing portion instead of the relatively solid connection element, a gentle transition between spout tube on the one hand and bag body on the other hand is achieved with less material.
  • the bag body remains practically up to the spout even in the area bulbous and thus wrinkle-free around the spout. Accordingly tension-free is the bag material with the result that even with high dynamic load no risk of breakage, especially not the risk of breakage of a metallic barrier layer.
  • the funnel-shaped or cone-shaped sealing section is relatively thin-walled.
  • the wall thickness of the cone section is about 30 to 50% less than the wall thickness of the spout. Nevertheless, sufficient stability is ensured, in particular if the cone-shaped sealing portion is circular or elliptical in cross-section.
  • the packaging is closed on the head side by a top seal, with the funnel-shaped or cone-shaped sealing section of the pouring tube being sealed in between.
  • the sealed joint is either a heat-seal or ultrasonic seal compound.
  • S hegekb cut an annular disc-like perimeter flange as a sportsport holder and / or
  • two fins are formed on the cone-shaped sealing portion diametrically to the longitudinal axis of the same, which are sealed in the finished packaging within the top seam, ie extending in the longitudinal direction of the top seam.
  • the two fins are preferably thin-walled. They have a wall thickness which may even be less than the wall thickness of the film material for the bag body. For a particularly tight connection of the top seam is achieved at the cone-shaped sealing portion. Also, the strength of the bag is increased in this area, it must be remembered that it is always critical areas for Üsbergs between bag film and sealed pouring devices in terms of stability and tightness.
  • the packaging may be formed tubular and at least in the head area diametrically to the packaging longitudinal axis in each case with the formation of a W-fold (gusset) fed or wound inward.
  • the mentioned W-fold (gusset) is then fixed in the region of the top seam, preferably by mutual sealing.
  • FIG. 1 shows the head region of a packaging (foil bag) designed according to the invention in a perspective view
  • FIG. 2 shows the head region of the packaging according to FIG. 1 in a narrow-side view corresponding to arrow II in FIG. 1;
  • Fig. 3 is a view corresponding to FIG. 2 showing the action of

  • the bottom of the tubular film bag 10, which is likewise not shown here, may be formed as a standing floor.
  • a bottom seam according to the head seam 11 is conceivable.
  • a pouring tube 13 is sealed, which can be closed with a screw cap, not shown.
  • This Ausgußrschreibchen has a relatively massive two-cornered connection element 14, whose cross section is formed by two symmetrically oppositely directed circular arcs.
  • the bag film is sealed, while continuing the top seam 11. Due to the orientation of the circular arc heat 15 parallel ZXLT bag longitudinal axis 12 is formed when filled bag immediately following the circular arc walls 15 each have a relative large dent 16, which gradually merges into a belly 17 in the direction away from the spout. Also folds 18 are formed in the region between the dent 16 and the top seam 11, under which the strength or stability of the bag material suffers, especially under dynamic load during transport.
  • the pouring tube 13 has a funnel-shaped or cone-shaped sealing portion 19, to which the packaging film is ansiegelbar.
  • the packaging is closed at the top by a top seal seam 11, wherein between this top seal seam 11 of the cone-shaped sealing portion 19 is sealed.
  • the sealing of the cone-shaped sealing portion 19 thus takes place in a similar manner as the sealing of the connecting element 14 according to FIG. 4.
  • the pouring tube is still a closure cap, in particular screw 20 assigned. This and the pouring tube 13 thus define a cap closure.
  • the cone-shaped sealing portion 19 is circular in cross-section. However, it may as well be oval or eüipsenfötmig designed.
  • the cross section may also be formed in a triangular manner.
  • annular disc-like peripheral flange 21 is arranged between the Ausgußrschreibchen 13 and the cone-shaped sealing portion 19 .
  • This serves as a transport holder and / or stop for sealing tools, in particular ultrasonic sealing jaws 22, 23 according to FIG. 3, which are movable in the direction of the double arrows 24 below the peripheral flange 21 to the cone-shaped sealing section 19 and can be moved away therefrom, and for the purpose of sealing the packaging film to the cone-shaped sealing portion 19 below the peripheral flange 21.
  • sealing jaws 22, 23 and Circumference flange 21 may still be provided a townis tion, if it is in the sealing jaws 22, 23 to heat seal jaws.
  • the cone-shaped sealing portion 19 also has the advantage that when sealing between the jaws 22, 23 is a kind of self-centering the spout arrangement. In this respect, the cone-shaped sealing portion 19 also represents an advantageous solution on the production side.
  • the wall thickness of the cone-shaped sealing portion 19 is significantly less than the wall thickness of the Ausgußrschreibchens 13, in particular by about 30 to 50% less. Despite this lower wall thickness, a sufficiently high stability is achieved in the connection area between the bag body and spout. Compared with the prior art according to FIG. 4, considerably less material is used for the pouring device in the described embodiment.
  • the latter has two fins 25, 26 which are formed diametrically to the longitudinal axis 12. These are, as Fig. 1 as well as Fig. 2 reveals, sealed in the finished package within the top seam 11.
  • the packaging is preferably tubular and, at least in the region of the head, is drawn or wound inward diametrically to the longitudinal axis 12 of the packaging, with the formation of a W-fold (gusset 27).
  • the W-fold or gusset 27 is fixed in the region of the top seam 11 by mutual sealing. The latter construction is indicated in FIG. 1.
  • Fig. 1 shows that the bag body is formed immediately after the cone-shaped sealing portion 19 bulging outward. There are no inward dents. Also, no wrinkles corresponding to the wrinkles 18 are to be feared. This gives a high filling volume without overstressing the bag film. The risk of foil breakage or fracture of at least one metallic barrier layer is considerably lower than in the prior art. Due to the smooth transition between bag film and spout device there is also no risk of leaks or material fatigue. Due to the bulbous shape of the bag up to the top seal, the bag can be emptied completely and without residue after aseptic treatment.
