Definitions

  • the invention relates to a microwave bag foil suitable for microwaves, especially for cooking Frozen products in the microwave, according to the generic term of claim 1.
  • Microwave bags are used in many different ways today used to reheat or microwave food prepare. For example, Microwave bag known with where corn kernels are made into popcorn or e.g. vegetables can be warmed up or prepared.
  • FIGS. 1a, 1b A typical tubular bag-made one Microwave bags are shown in FIGS. 1a, 1b.
  • FIG. 1a shows a tubular bag 1 with two transverse seams 2 and a longitudinal seam 3 (back seam). At the seams 2,3 there are large welded sealed seams that are manufactured in the sealing process.
  • the microwave bag 1 has an interior 4, in which is usually the food product (not shown), such as e.g. Vegetables, rice etc.
  • Such known tubular bags 1 can e.g. used to be low-liquid foods warm. Food with a high liquid content can on the other hand, should not be prepared, since the interior 4 resulting steam inflate the microwave bag 1 too much would. Cooking food is particularly easy with one Such a microwave bag 1 is not possible because the bag 1 would be destroyed by the resulting vapor pressure. Frozen products in particular, which freeze you can have a relatively high proportion of liquid, therefore such a microwave bag 1 is not warmed up or be cooked.
  • Microwave bags made of foil suitable for microwaves create in which also dishes with a higher liquid content and in particular frozen or reheated frozen products can be without the microwave bag through the Warming up or cooking pressure is destroyed.
  • the essential idea of the invention is one Microwave bags, especially a tubular bag at least one of its welds with pressure relief valves provided by the when the food is heated resulting steam can escape to the outside.
  • the Pressure relief valves are preferably implemented in such a way that the microwave bag preferably before heating is completely closed and the valves only become worn automatically open the steam pressure generated during heating.
  • the pressure relief valves are e.g. around unwelded, in at least one of the bag seams arranged areas that have a weak point in the prey seam form.
  • the unwelded areas can e.g. so be designed so that it is on one side close to the Reach inside the bag and on the other side communicate with the outside space. But you can too e.g. communicate with the inside of the bag and close to reach the edge of the microwave bag.
  • the Pressure relief valves open automatically when the welded seam opens easily with increasing vapor pressure.
  • the steam generated during warming up can thus escape to the outside escape.
  • the unwelded areas are preferably towards the interior tapered towards the outlet cross section for the To keep steam relatively small. As a result, not everyone can Steam escapes all at once, and that in the microwave bag Food that is present is cooked better and can in particular do not dry out.
  • the microwave bag according to the invention is preferably a Tubular bag with two welded cross seams and one welded back seam.
  • the pressure relief valves are preferably in at least one of the two transverse seams.
  • In the back seam is preferably no pressure relief valve is provided to a To prevent fluid leakage when the Microwave bag with the back seam down in the Microwave lies.
  • the seams of the microwave bag are preferably made of several individual linear welds.
  • the unwelded valve areas arranged to be at least one of the linear ones Cut welds, i.e. interrupt.
  • the cross seam preferably not or only very weakly welded. Thereby the seam opens much easier.
  • the cross and back seams of the microwave bag sealing seams welded over a large area, in where unwelded valve areas are provided.
  • Fig. 2 shows a microwaveable film, e.g. a composite film made of PET / PE or a polyester / PP film, existing tubular bag 1 with two transverse seams 2 and one Back seam 3.
  • the cross and back seams 2,3 consist of several linear welds, essentially run parallel.
  • Pressure relief valves 5 are provided, which serve to excess To let steam escape from the inside of the bag.
  • the pressure relief valves 5 are as unwelded areas realized within the transverse seams 2, which e.g. on one side close to the interior 4 of the microwave bag 1 range and in on the other side with the outside space Connect.
  • the unwelded areas 5 can also be reversed and with the interior in Connect and reach close to the edge of the bag.
  • the unwelded areas 5 are arranged such that the microwave bag 1 completely before heating is airtight. Only when the food is warmed up the transverse seam 2 opens slightly with increasing internal pressure, see above that the steam can escape through the valves 5.
  • the pressure relief valves 5 are to the interior 4 of the Microwave bag 1 is preferably tapered to the outlet cross section for the steam is relatively small hold. As a result, a valve 5 remains on even when the valves are open get relatively high vapor pressure in the microwave bag 1, so that the contents of the bag can be optimally cooked.
  • the pressure relief valves 5 are preferably located in the Cross seams 2 and not in the back seam 3. This can that liquid is prevented through the seam 3 can escape when the microwave bag 1 with the Back seam 3 lies down in the microwave.
  • the pressure relief valves 5 according to the invention can for example by means of sealing jaws, which have corresponding recesses.
  • the width of the transverse seams 2 can be, for example, 5 mm to 10 mm be.
