- the inventive measure is achieved in an advantageous manner that in the area of the zipper reliable opening of the device for the escape of steam is ensured. Due to the relatively large formation of the interior of the bag facing the ends of the openings in relation to the bag outer facing the ends of the openings of the
- Bag exterior ensures that the pressure necessary for steam cooking is maintained inside the bag. This in turn has a positive effect on the cooking or Dampfgareigenschaften the bag.
- a system of communicating channels is realized which ensures that the vapor pressure does not concentrate at individual locations and possibly open the zipper there by deformation of the bag. Rather, the system of channels, for example, allows steam to enter the system at one location and exit the system at different locations. This avoids local stress on the bag and consequently also on the zipper because the bag does not deform at individual points due to the increased gas pressure.
- the system of channels realizes a kind of labyrinth, into which the steam can enter at different points or positions, spread out in it and finally exit at different points or positions.
- the solution according to the invention has as an outstanding feature that the bag-internal vapor pressure is controlled by the passage geometry and the fixation of the zipper on the film inside of the bag using a tool for heat sealing carried out, which has only minor modifications in relation to the prior art and on a machine (eg a conventional standing bag making machine), with which the manufacturing method according to the invention is carried out, with known performance and in particular without further adaptations of this machine to the external
- Tool geometry can be used. This is in appreciable contrast to known solution, which often requires a reduction in performance and / or significant changes in terms of the process-relevant steps or in relation to the machine.

- At the edges of the zipper between the front and rear wall of the bag is fixed.
- the zipper is preferably made of a heat-resistant material such as H DPE, polyethylene-polypropylene copolymers or polypropylene.
- Such zippers are commercially available and have from the inside to the outside of the bag strong toothing properties, whereby an initial resistance is given when opening the zipper. This ensures that a high vapor pressure can be achieved in the package.
- the asymmetric toothing ensures that the zipper is easy to open from the outside.
- Said glass plate effect can also be influenced by the choice of the mechanical parameters of the film / films.
- the tendency for a pronounced glass plate effect is namely increased in a soft film, whereas there is a tendency for a less pronounced glass plate effect in a stiffer film.
- This finding can also be used in the choice of the material of the zipper or the base of the zipper, which is heat-sealed with the sealing layer of the bag.
- polypropylene is used instead of polyethylene
- a material which has a higher density and thus also forms a stiffer structure compared to a polyethylene structure.

- Fig. 2, 7 denote the recesses for the formation of the air or vapor passage openings in the transverse direction of the zipper 2, 8 the
- FIG. 3 shows a bag 20 according to the invention - more precisely a cross-section through such a bag 20 transversely to the longitudinal direction of the zipper Z.
- the bag 20 is a stand-up pouch which, when filled, stands upright by its bottom geometry without any further support.
- the bag 20 is bounded by a wall 21 and has a bag interior 23.
- the bag 20 has a top seal 25.
- Below the top seal 25 is a tear zone 26, with the help of the head seal 25 can be separated. After tearing away the head seal 25 along the tear zone 26, a head portion 24 of the bag is freely accessible.
- the zipper Z has a female part 28 and a male part 27.
- the male part 27 has a first base 29.
- the female part 28 has a second base 30.
- the first pedestal 29 is sealed to the inner surface (50) of the plastic film forming the wall 21 in first seal portions 31.
- the second pedestal 30 is sealed to said inner surface (50) in second seal areas 32.
- the two sealing areas 31 and 32 and the zipper Z are shown greatly enlarged. Through the second seal areas 32 extends a section line - or area A-A.
- FIG. 4 A section along this line or surface AA through the second sealing regions 32 is shown in FIG. 4.
- the second sealing regions 32 are bounded on the one hand by a first recess 15 in the longitudinal direction and by four second recesses 13 in the transverse direction. At the left or right end of the first recesses 15 in the longitudinal direction in each case a final third seal area 14 is visible.
- Steam 16 which flows from the interior of the bag 23 in the direction of the head region 24 through the channel system of the second sealing region 32, is also indicated schematically.
- the steam 16 is an optimal way through the Labyrinth of the channel system through, where not necessarily steam entering at a position / position in the labyrinth at the same position / position in the transverse direction of the zipper Z must exit again from the labyrinth, but can also leave the labyrinth via adjacent exit points.
- the relatively large inlet openings in the area of the interior of the bag 23 allow for the heating and the release of steam 16 easy opening of the interior 60 of the bag 20 facing ends of the labyrinth and thus a smooth flow of steam 16 into the labyrinth.
- the entering into the labyrinth steam 16 can spread optimally in the labyrinth and easily emerge from the labyrinth, so that the risk of vapor concentration at individual points - and thus a pressure concentration and concomitant deformation of the bag 20 at these points - reliably avoided and thus no unnecessary stress on the interlocked male and female parts 27 and 28 of the Zipper Z is exercised. As a result, an unwanted partial or large-scale opening of the zipper Z is reliably avoided.
- FIG. 5 another embodiment of a bag 20 according to the invention is shown in frontal view of the front side of the bag 20.
- the zipper Z is only roughly schematic and indicated by its limitations and shown substantially transparent to make the underlying labyrinth visible.
- the first recess 15 in the longitudinal direction of the zipper Z which extends substantially below the respective male part 27 and the female part 28 of the zipper Z, respectively.
- a first base 29 protrudes from the plane of the drawing.
- three second recesses 13 in the transverse direction of the zipper Z in the direction of the bag interior 23 (the interior 60 of the bag 20 facing ends of the labyrinth) have substantially larger inflow than in the direction of the head portion 24 (the exterior 70 facing Ends of the labyrinth) of the bag 20.
- the third sealing regions 14 bound the first recess 15 in the longitudinal direction of the bag 20 and at the same time also form the longitudinal sealing seams of the bag 20.
- the openings emerging from the head region 24 openings of the labyrinth Steam 16 is shown schematically.
- this vapor 16 can, of course, only escape from the bag 20 when the head of the bag 20 has been torn away along the tear zone 26, which in the present case was created by laser weakening the film of the bag 20.
- the tool 40 for establishing the connection between the base 29 of the part 27 and the base 30 of the part 28 of the zipper Z and the inner surface of the plastic film of the bag 20 is shown.
- This tool 40 has a first tool part 17 and a second tool part 18, which are designed to be substantially symmetrical to one another, and have sealing zones 40A corresponding to one another, by means of which the first sealing regions 11 and the second sealing regions shown in FIGS 12 are feasible.
- the sealing zones 40A longitudinal recess or longitudinal recess 19A, by means of which the first recess 15 is realized in the longitudinal direction of the zipper Z.
- the two tool parts 17 and 18 are - as shown in Fig. 7 - assembled in use (see arrows Pl and P2), so that the sealing zones 40A are opposed and between them the plastic film or positioned on the plastic film respective male part 27 or the female part 28 are located.
- the first base 29 and the second base 30 is finally connected to the inner surface of the plastic film, so that the first sealing region 31 and the second sealing region 32 with the structure of the recesses 15 and 13 arise.
- transverse notches 19B are formed which substantially form a truncated triangle truncated triangle structure or in other words a truncated cone cross-sectional structure and are provided for forming the second recesses 13 in the transverse direction of the zipper Z.
- the transverse notches 19B realized between the first base 29 and the second base 30 thus have a conical taper from the interior of the bag 23 to the head region 24, whereby a valve effect is formed which counteracts the escape of the steam 16.
- the dimension and the geometries of the recesses are harmonized with the internal opening force of the Zipper Z and the bag size in that the steam pressure during cooking does not exceed the force required to open the Zipper Z.
- a bag size of 200xl40mm with a zipper with 12 / 25N / 50mm opening force each 3 triangular openings with a width of 20/5 mm are placed both on the front and on the back of the bag.
- the larger width information always refers to the product direction of the opening.
- a zipper with an opening force of 7.5 / 18N / 50 mm can be used for relatively large openings.
- a zipper with an opening force of 12/27 N / 50 mm is preferred.
- the notation eg 12 / 25N / 50mm is to be understood as meaning that a force exerted by the exterior of the bag on the zipper of 12N per 50mm is necessary whereas force from the inside of the bag to the zipper of 25N per 50mm is needed to open it.
- the shape of the taper can not follow a straight line but can also follow a curve, as shown in FIGS. 8 to 10. Stair-like structures with sharp edges can also be used.
- first sealing area 31 and the second sealing area 32 need not be provided at identical locations. Rather, the formed in the respective sealing region 31 and 32 second
- Recesses 13 in the transverse direction of the zipper Z also exist with respect to the male part 27 and the female part 28 at different locations, which possibly contributes to a better stress reduction in the area of the zipper Z.
- only one of the sealing regions 31 or 32 can have said second recesses 13 in the transverse direction of the zipper Z.
