Definitions

  • the invention relates to a filler neck or bung for foil containers or bags made of polyethylene or the like according to the preamble of claim 1.
  • the filler part is made of polyethylene (PE) or a linear low-density polyethylene (LLDPE) in such filler neck or bung in order to optimally ensure the welding with a polyethylene layer of the container or bag film.
  • a closure or tap part is usually made of polypropylene (PP).
  • Sterilization using a steam jet which is widely used today, cannot be used for a sheet made of PE because such a sheet is not sufficiently heat-resistant.
  • the invention has for its object to avoid these difficulties in a filler neck or bung according to the preamble of claim 1 in that the bung is designed so that it is dimensionally stable even with high mechanical and changing thermal stresses, but on the other hand also a perfect tight weld connection between the flange part and the film material of the film container or bag is ensured in a simple manner. Steam sterilization should also be possible.
  • the invention ensures optimum dimensional stability of the bung part on such filler neck or bungs, which also enables optimal rotation of the closure part or tap part without increased friction.
  • Such filler neck or bung can be easily produced on injection molding machines with two extruders.
  • a reinforcement can be installed at the interface between the PP base body of the sheet pile part and the part or parts or the covering made of polyethylene or the like by toothing, by block or column formation or other geometries. At the same time, steam sterilization is possible through the appropriate choice of material.
  • Another possibility is to spray a PE layer or the like onto the carrier body made of PP onto the surface of the flange part. This also avoids the frequent formation of waves on the flange part of the bung, since PP is harder as a carrier material than the PE coating and therefore ensures greater stability, dimensional accuracy and turning ability.
  • both the bung 3 and the closure part 4, which are on the bung 3 between a closing and a Open position is rotatable, made of polypropylene (PP) or the like, while the flange part 5 of the sheet part 3 either completely or at least partially made of a polyethylene (PE, LLDPE) with or without EVA or the like and with or without other additional additives is formed.
  • PE polyethylene
  • LLDPE polypropylene
  • Polypropylene and various other sprayable plastics are sufficiently heat-resistant for steam sterilization.
  • the bung part 3 in addition to the rotatable closure part 4, also consists entirely of a polypropylene or the like, a coating or a layer 6 of a polyethylene (PE, LLDPE ) with or without EVA or the like with or without other additional additives for welding to the container or bag film 2 or with a suitable PE layer of the bag.
  • PE polyethylene
  • the container or bag film 2 is to be welded to the underside of the flange part 5, this can, as shown on the right-hand side of FIG. 1, be provided with such a coating 6 made of a polyethylene (PE, LLDPE) on the underside of the flange part 5 or without EVA or the like for welding to the container or bag film 2 or a PE layer of the bag, this coating or layer 6 also being pulled up further on the inside of the sheet part 3 and with sealing lips 7 for sealing between the sheet part 3 and the closure part 4 can be formed in one piece.
  • PE polyethylene
  • the coating or the layer 6 made of a polyethylene (PE, LLDPE) with or without EVA or the like on the flange part 5 can also extend around the flange edge from the top of the flange Extend continuously to the underside of the flange, so that an optional welding with the container or bag film 2 is possible both on the upper side of the flange and on the underside of the flange without structural changes.
  • the coating or the layer 6 can extend further from the flange part 5 on the inside of the bung or, if appropriate, also on the outside of the bung.
  • the sheet part 3 is formed with a continuous support body 3a made of polypropylene (PP), which has a continuous coating 6 made of a polyethylene (PE, LLDPE) with or on both the top of the flange and on the outside of the sheet part 3 is provided without EVA or the like, on which the sealing lips 7 for sealing between the sheet part 3 and the closure part 4 are also formed in one piece.
  • PP polypropylene
  • PE polyethylene
  • LLDPE polyethylene
  • FIG. 4 shows a further simplified embodiment of such a filler neck or bung 1, wherein in the left part of FIG. 4 the flange part 5 integrally formed with the bung part 3 has only a small radial width and on its underside with a cover 6 that projects radially outwards is formed from a polyethylene with or without EVA or the like for welding to the container or bag film 2.
  • the cover 6 extends into the cylindrical section of the sheet part 3 and is firmly toothed with it, as in all the other exemplary embodiments shown.
  • the covering 6 is formed from a polyethylene with or without EVA or the like over the entire flange underside and also extends on the inside of the sheet part 3, while sealing lips 7 from a polyethylene or the like on the outside of the base body of the sheet part 3, which is made of polypropylene, are integrally formed with it for sealing against the rotatable closure part 4 of polypropylene or the like which overlaps the sheet part 3.
  • the closure member 4 is rotatably arranged inside the bung 3.
  • the sheet part 3, like the closure part 4, is made of a polypropylene or the like and is formed on the flange part 5 with a coating or a layer 6 made of a polyethylene with or without EVA or the like for welding to the container or bag film 2, the coating 6 can also be designed on the underside of the flange as required if necessary, can also extend further up on the bung 3 itself.
  • the flange part 5 can also be formed entirely from a polyethylene (PE, LLDPE) with or without EVA or the like in the form of a ring and can be firmly connected in one piece to the sheet part 3 by a smooth, jagged or similarly shaped connection 8 , as the embodiment of Figure 6 shows.
  • PE polyethylene
  • LLDPE polyethylene
  • EVA electroactive polymer
  • the illustration of a closure part has been omitted for reasons of simplification.
  • the flange part 5 is made entirely of a PE, for example by spraying in a mold, and has a narrow flange 9 in the area of the connection 8 for connection to the heat-resistant and dimensionally stable sheet part 3, which flange is firmly enclosed by a corresponding collar 10.
  • Collar 10 is formed in one piece with the bung 3 and can be molded together with this to the prefabricated flange 5, so that an inseparable one-piece connection is formed.
  • the film bag 2 can now be welded to the underside or the top of the flange part 5.
