Definitions

  • the invention relates to the packaging of foods, particularly frozen foods, for steaming them in a microwave oven.
  • US 2006/0186116 A use a semi-rigid airtight bag for storing, dispensing and microwaving food.
  • the packaging described therein comprises a flexible bag portion wrapping a rigid portion serving as a bottom and made, for example, polypropylene or food carton.
  • the package also includes a bell-shaped vent device to open under the pressure generated by the steam generation during cooking.
  • Packaging of the type holding bag is known from GB 2 414 226 A .
  • This packaging is completely waterproof and is intended exclusively for the storage and reheating of pre-cooked and sterilized foods. It comprises different variants of weakened welding bypassing a steam passage zone.
  • the steam production Microwave heating is certainly real but relatively low. This is the reason why the complex devices and small section of these two documents are not at all suitable for steam cooking, especially frozen products.
  • the objective of this invention is to enable the end user to easily cook in a natural and healthy way by steaming in the microwave oven his food frozen or fresh without first opening the bag holding vertically and reduce the impact environmental waste in a ratio 5 to 7 in favor of the invention compared to bowls or other trays already known.
  • the permanent opening (s) is / are essentially centered on a horizontal axis.
  • the permanent opening (s) can be located essentially in an area between one-half and two-thirds of the height of the bag.
  • the bag may have a plurality of permanent openings on at least one of the first and second pieces of film and that the openings on the same piece of film are grouped together.
  • the permanent opening (s) is (are) made by removal of material.
  • the zone where the weld is weakened is essentially in the form of a horizontal line.
  • the zone where the weld is weakened is essentially in the form of an inverted V.
  • the bag may have at least one precut area at one of its side edges at a height of approximately half or less the total height of the bag.
  • the bag may be provided with a laser precut at the height of the precut zone so as to ensure controlled cutting of the bag.
  • the permanent opening (s) is / are essentially centered on a horizontal axis.
  • the permanent opening (s) (5) is / are essentially located in an area between one-half and two-thirds of the height of the bag.
  • the bag may have several permanent openings on at least one of the vertical walls and in that the openings on the same wall are grouped together.
  • the permanent opening (s) is (are) made by removal of material.
  • the figure 1 illustrates a vertical holding bag for frozen food packaging (natural vegetables, cooked vegetables, fish, ready meals, etc.)
  • the figure 2 illustrates a vertical holding bag for packaging fresh liquid food (omelettes, tortillas, cake dough, soups, marinades, coulis, etc.)
  • the figure 3 illustrates a vertical holding bag for the packaging of solid fresh foods (vegetables, cooked dishes, fish, etc.).
  • the figure 4 shows a bottom view of the holding bag according to the invention.
  • the vertical holding packaging bag shown in figure 1 comprises a first piece of plastic film 1, a second piece of pastic film 2 identical to the first forming the side walls of the bag and a third piece 3 serving as a base and bottom to the bag.
  • the pieces 1 and 2 are superimposed and welded together along their side edges 4.
  • the third piece is folded in half along the dotted line and connected to the other two 1, 2 also by welding at the lower edges 8 and at the bottom of the lateral edges 4.
  • the lateral zones of the piece 3 forming the bottom of the bag are welded to the corresponding areas of the pieces 1 and 2 forming the walls so as to form triangular zones 9. These are able to deviate from each other at each end of the bag so as to stiffen the bag and to allow vertical holding once filled.
  • this weld gives a thickness of 4 layers of film (in the case of a duplex film and 6 layers of film in the case of a triplex film) and thus allows the final consumer to be able to leave the dish immediately after cooking steam in the microwave oven without waiting for the cooling and especially without getting burned.
  • the bag is taken directly without waiting time and instinctively between two fingers by one of the corners of the bag holding vertically.
  • the reference 6 designates a precut allowing a tear initiation, thus making easy opening for the vertical holding bag, the consumer does not need to use a knife or a pair of scissors to open the bag.
  • the reference 7 designates a tear initiation performed at 50 to 60 mm from the base, but it is completed by a laser precut to ensure a straight opening of the bag holding vertically. In certain applications of ready meals or steam vegetables as in the automatic distribution, it is necessary to be able to consume the product directly in the packaging.
  • the bottom elevation of approximately 15 mm allows the positioning of the steaming food at the optimal distance from the microwave generator (magnetron). At 15 mm above the turntable the absorption of microwaves is maximum. For this reason we do not have the phenomena of ultra hot point and cold points, as on the heating of the trays or other bowls.
  • the bag of the figure that is specifically designed for applications for frozen products has 2 vents 5, one on each side of the film are placed between 5 and 7 cm from the top with a diameter of 0.4 to 0.8 mm depending on the cooking time required (plus the holes are small plus the pressure increases and cooking is fast and vice versa). Mastering the diameter and positioning is an essential element of the invention.
  • the bag illustrated at figure 2 allows the packaging of fresh solid products (vegetables, meat, fish, cooked dishes) under modified atmosphere (binary mixture of CO2 and N2).
  • the omelette can be consumed directly in the holding bag.
