Definitions

  • the invention relates to a flexible bag for beverages, food, animal feed and the like, with at least one sealed between two free edges of the bag closure.
  • the invention also relates to a method for producing such a bag, wherein the closure is welded, in particular by means of ultrasound, to the free edges of the bag.
  • Bags as storage and transport containers for beverages and other fluid media are well known and have become increasingly popular in recent times, as they require less space in the deflated state, as cans, bottles or other rigid containers.
  • a closure spoked
  • the welding of such a closure is usually carried out over three consecutive steps, for which several, respectively narrowing tools are used.
  • the area has proved to be problematic in which the two edges of the bag have a height jump due to the inclusion of the closure.
  • the welding causes a plastification of the edges and the closure, so that must be pressed with narrowing tools.
  • the invention has for its object to provide a bag and / or a method for producing such a bag, which has a closure, which offers greater security in terms of tightness and is easier to produce.
  • This object is achieved in a flexible bag for drinks, food, animal feed and the like in that the welded between the two edges body of the closure is formed at least partially frusto-conical.
  • the truncated cone shape of the welded body of the closure offers the possibility that by axial displacement of the body, the contact pressure of the body varies to the walls to be welded and thus can be set to a desired value.
  • the body to be welded can be welded by means of ultrasound or hot deformation.
  • the body tapers in the direction of the container interior. Will the closure after softening of the plastic, that is after the energy input is moved in the direction of the container interior, it is pressed against the insides of the free edges of the bag. Tolerance differences can thus be compensated relatively easily.
  • the body has a circular cross-section.
  • the body has a substantially elliptical cross-section, wherein the ends can leak like a wing. Irrespective of the cross section of the body of the closure, however, according to the invention it runs in the shape of a truncated cone so that it can be pressed against the edges of the bag by an axial movement.
  • an optimal investment of the body to the inner surfaces of the edges and an optimal seal of the bag interior to the environment is achieved in that the body is provided with one or more circumferential beads.
  • the contact pressure is thus concentrated on the apex lines of the circumferential beads, which in particular have a part-circular or tapered cross-section.
  • the pressing causes a material displacement in the region of the apex lines of the circumferential beads, so that small bumps can be compensated.
  • the circumferential beads are arranged according to the invention at a distance from each other.
  • Material can be displaced in the free space between the circumferential beads, which also has the advantage that the cone angle of the body can deviate slightly from the cone angle of the tools receiving the edges of the bag, such as sonotrode and anvil.
  • material displacement on the body of the closure whose angle is adjusted to the tool angle. This allows manufacturing tolerances the closure or a transport-related offset easily be compensated.
  • the closure or at least the body of the closure of a thermoplastic material in particular polyethylene (PE).
  • PE polyethylene
  • Polyethylene has the significant advantage that it is very easy to work with ultrasound and behaves neutral towards food.
  • the disposal of polyethylene is also possible together with the bag easily.
  • the closure In order to be able to move the closure axially, it has an engagement surface, e.g. for an ultrasound sonortode or an anvil. Ultrasonic or thermal energy may be introduced into the closure via this attack surface so that it is not only passive, i. over the free edges of the bag, but also actively plasticized.
  • an engagement surface e.g. for an ultrasound sonortode or an anvil. Ultrasonic or thermal energy may be introduced into the closure via this attack surface so that it is not only passive, i. over the free edges of the bag, but also actively plasticized.
  • the closure After plasticizing, the closure is displaced in the direction of the bag via the engagement surface on which the tool is resting, so that the body of the closure can still be supplied with ultrasound or thermal energy during the pressing process.
  • the object stated at the outset is also achieved by a method for producing a bag having the above-mentioned features, whereby the closure is welded to the free edges of the bag by means of ultrasound or thermal energy, and the closure is sealed off in the direction of the bag interior and thereby on the inner surface of the edges is pressed.
  • This shift can take place over a predetermined distance or over a predetermined force.
  • the closure can be displaced axially by 0.01 to 0.5 mm, wherein at a cone angle of 6 ° to 10 °, in particular 6 °, a corresponding pressure on the laterally adjacent edges is effected.
  • FIG. 1 shows a schematic representation of a side view of a bag with a closure to be welded in
  • Figure 2 is a plan view of the arrangement of Figure 1 with laterally applied tools
  • FIG. 3 shows a section III-III according to Figure 2; and ' Figure 4 shows the view according to Figure 3 with shifted closure.
  • FIG. 1 shows, in perspective and schematically, a bag, designated overall by 10, consisting of a plastic film or a laminate with a plastic film, in whose upper side 12 a closure 14 is to be welded in such a way that it comes to lie between the two edges 16 and 18 , so that the inner surfaces 20 of the edges 16 and 18 come to rest on the body 22 of the closure 14.
  • the body 22 of the closure 14 is substantially frusto-conical in shape, and terminates at its upper side in a projection 24 on which a closure lid (not shown) can be clipped, screwed or otherwise fastened.
  • the body 22 of the closure 14 has circumferential bulges 26 on its outer side, which for the sake of simplicity are reproduced only on the closure 14 shown in FIGS. 1 and 3.
  • FIG. 2 shows the view in the direction of the arrow II according to FIG. 1, wherein the closure 14 has been inserted into the bag 10, that is, between the two edges 16 and 18, such that the inner surfaces 20 of these edges 16 and 18 abut Body 22 of the closure 14 abut.
  • FIG. 2 shows a first tool 28 (sonotrode or anvil) and a second tool 30 with which the edges 16 and 18 are pressed against the body 22 of the closure 14.
  • the tool 28 may be designed as a sonotrode or as an anvil and the tool 30 as a sonotrode.
  • both tools 28 and 30 may be designed as a sonotrode, in which case the tool holding the closure 14 32, which is shown in Figures 3 and 4, is designed as a sonotrode or an anvil.
  • the tools 28 and 30 have a hollow cone-shaped recess 34, which is also clearly visible in Figures 3 and 4.
  • the cone angle of the recess 34 largely corresponds to the cone angle of the body 22 of the closure 14th
  • the closure 14 is inserted so far between the two edges 16 and 18, that the peripheral beads 26 abut the inner surfaces 20 of the edges 16 and 18 and the edges 16 and 18 in turn on the surfaces of the recesses 34 of the tools and 30 to come lie. Then, via the tools 28, 30 and / or 32, ultrasonic energy is introduced into the edges 16 and 18 and optionally into the closure 14 so that the edges 16 and 18 in the regions 36 and 38 weld together and in the region of the closure 14 the peripheral beads 26 and the edges 16 and 18 plasticize.
  • the tool 32 is moved in the direction of the arrow 40 ( Figure 4) and thereby the closure 14 further pressed into the recess 34 of the two tools 28 and 30, so that the peripheral beads 26 of the body 22 with high force against the inner surfaces 20 of the two Edges 16 and 18 are pressed.
  • an intimate connection of the body 22 is provided with the edges 16 and 18, which is not only mechanically extremely stable, but also sealed against fluids that are in the bag interior 42.
  • the tool 32 is thereby moved by a predetermined distance 44 or by means of a predetermined force acting in the direction of the arrow 40.
