Definitions

  • the invention relates to a stand-up pouch made of a heat-sealable film, with a front and a back, which are connected to one another at their edges, wherein a resealable screw closure is provided in the front or the back, which has a connection piece on which a thread is applied, which is in engagement with a thread of a releasable screw cap.
  • So-called disposable bags are known several times in practice. They are used, for example, to fill beverages, which are often sachets, ie with an amount of content that is consumed by the consumer on one occasion. Such bags generally have a weakening point on their front side which can be pierced with a drinking straw, the contents of the bag also being removed via the drinking straw. It is also common, depending on the volume of the bags, to cut these bags open so that the contents can be emptied. Bags of this type can be disposed of easily since they take up only a small volume. However, the consumer is forced to always empty the entire bag or to empty the bag in the case of filling non-drinkable liquid, since bags of this type are not resealable.
  • a stand-up pouch of the type mentioned is known from DE-OS 17 86 019.
  • This bag has a screw cap attached to the flat side, which is attached with its flange to the outside of the bag. With such stand-up pouches, leaks can occur at the closure; the sometimes high moments that occur when the screw cap is closed again can lead to damage.
  • the socket of the screw cap passes through the bag and is attached at its inner end with a sealing flange on the inside of the bag, that the sealing flange has a bevelled outer edge which together with the associated side of the bag a radially after forms an externally opening, V-shaped circumferential groove which is at least partially closed by the sealing layer melted during sealing.
  • the diameter of the sealing flange is at least twice as large as the diameter of the connecting piece, in order to be able to easily cope with the torque exerted by the screw closure.
  • this arrangement of the screw cap has the advantage that the screw cap is arranged at a point at which the respective bag side is bordered on three sides, namely the long sides and the upper edge by the resistance of the relevant bag side increasing sealing proximity. Even at high torques, the composite film does not tend, or only to a tolerable extent, to warp. Depending on the distance between the sealing seams and the sealing flange of the screw cap, the film thickness of the composite film can therefore be reduced further.
  • a stand-up pouch according to the invention is shown in a perspective view in FIG.
  • the stand-up pouch consists of a heat-sealable composite film 1, in the exemplary embodiment shown here of an aluminum film which is plastic-coated on both sides.
  • the inner, sealable plastic layer is designated by the reference number 10, while the aluminum layer has the reference number 11 and the outer plastic layer has the reference number 12.
  • the bag has a front side 2 and a rear side, not shown in FIG. 1. At the lower end of the bag, a bottom 3 is inserted, which is connected to the front 2 and the back via sealing seams 4. Above the bottom 3, the front 2 and the back are also connected to one another via sealing seams 5. Sealing the front 2, the bottom 3 and the Reverse happens in the conventional way under the influence of heat and pressure.
  • a reclosable removal opening 6 is provided in the upper region of the bag, which, as better shown in FIG. 2, has a nozzle 7 penetrating the bag or its front side 2 and projecting outwards inner end is fixed with a sealing flange 8 on the inside 9 of the bag.
  • the removal opening 6 is designed as a screw closure
  • the connector 7 has an external thread which can be brought into engagement with an internal thread of a releasable screw cap 13.
  • the screw cap is attached to the front 2 of the bag by sealing the composite film 1 with its sealable plastic layer 10 onto the sealing flange 8 of the screw cap.
  • the outer edge 14 of the sealing flange 8 is bevelled in such a way that it together with the associated bag side, i.e. the front 2 forms a radially outwardly opening, V-shaped circumferential groove 15.
  • the angle of inclination ⁇ of the edge 14 is preferably 45 °.
  • the plastic layer 10 is melted. Part of the melted plastic layer reaches radially outwards and fills the circulation groove 15. Because of the V shape the circumferential groove 15 creates a converging gap from which the melted plastic material is sucked. This creates a particularly intimate connection between the outer edge 14 of the sealing flange 8 and the composite film 1.
  • the diameter D of the sealing flange 8 is at least twice as large as the diameter d of the connector 7. In the exemplary embodiment shown here, the diameter D is even approximately 2.5 times as large.
  • the screw closure is closed by screwing the screw cap 13 onto the socket 7, a torque is generated which must be transmitted through the sealing flange 8 to the front 2 of the stand-up pouch.
  • the radial distance from the outer edge of the sealing flange to the center of the screw closure 6 is as large as possible. This can be achieved, on the one hand, by selecting the diameter D of the sealing flange 8 to be large, an effective effect, however, being achieved only if it can be ensured that the sealing flange 8 is also firmly connected to the composite film 1 at its outer edge 15 . Otherwise, the choice of a large diameter D is of little use.
  • Stand-up pouches of this type can be used in particular for filling liquids of all kinds.
  • the screw cap of the screw cap can of course also have a safety ring in a known manner, so that it can be recognized whether the screw cap has already been opened.
