Definitions

  • the present invention relates to a packaging for food products according to the preamble of claim 1.
  • Such packaging is known from document US-A-4351997.
  • Food products of the frozen meal type are generally found in metal trays, for example aluminum.
  • the trays are closed by a cover, for example an aluminum foil or cardboard and placed in an overwrap carton.
  • a cover for example an aluminum foil or cardboard and placed in an overwrap carton.
  • To cook or reheat the product remove the lid and place the tray in an oven.
  • Other culinary products for example intended for the easy preparation of quiches, pies or pies based on flan, salted or sweetened, can consist of a base of precooked dough already placed in a metal tray and a sachet containing ingredients of the filling, for example in dehydrated form.
  • the housewife can simply add to the dehydrated ingredients the necessary quantity of liquid, for example milk and egg, preferably mixed beforehand, then bake the product in the oven.
  • the metal trays are perfectly suited for conventional convection ovens or infrared radiation, but have serious drawbacks vis-à-vis microwave ovens.
  • the traditional metal tray is opaque to microwave radiation and is not suitable in microwave ovens as there may be arcing in the oven cavity, which can damage the walls of the oven, or radiation return towards the magnetron, which can damage it if the protection is insufficient, for example in ovens of relatively old design.
  • the cooking of certain products is very uneven because the metals in the conductive sheet are not transparent to the microwaves and the heating intervenes from the top to the bottom. Consequently, the upper layer preferentially undergoes the action of the wave, which is also weakly penetrating, with excessive heat production and evaporation of the water. This leads, in particular for frozen products, to inhomogeneous cooking with a cold bottom layer and also still frozen while the top layer is dried out, or even burnt.
  • the use of a microwave oven leads to a movement of the product which is detrimental to correct coagulation of the blank. It is not smooth but its texture is more like that of scrambled eggs.
  • Cooking is not only heterogeneous but greatly slowed down.
  • US-A-3,865,301 describes a container with openings, suitable for several ingredients of a sandwich-type food product, which must be heated or baked to different degrees, which container is opaque to micro radiation. -waves excluding windows transparent to radiation.
  • Patent US-A-4,081,646 illustrates a tray made of a material transparent to microwaves and comprising several compartments, a cover formed of a material transparent to microwaves and suitable for the tray and a box with openings having opaque walls. microwaves and openings at pre-determined locations, into which the tray and lid are inserted, so that a control is obtained of the amount of radiation received by each of the individual components of the meal.
  • US-A-4,351,997 relates to a tray made of material transparent to microwave radiation, the inner surface of the side wall or corners and the upper part thereof constituting the horizontal edge are covered with a material. metallic opaque to microwave radiation. The realization of such a tray is complicated.
  • patent US-A-4,439,656 relates to a utensil made of material transparent to microwaves in which a metal tray is placed and which, once filled with water, allows the protection of the microwave oven as well than uniform heating of a food.
  • the consumer does not always have such a utensil sold independently of the food.
  • such a utensil can not be adapted to all forms of trays, so it would take several.
  • the invention makes it possible to solve the problems associated with known devices by simple means, sold together with the food and constituting part of its packaging.
  • the packaging according to the invention is characterized in that the cover is made of a material transparent to microwaves, that said cover constitutes a receptacle for a microwave absorbing fluid, of so as to surround the tray with said fluid during reheating or cooking, once the lid is turned over and the tray placed inside.
  • a tray can be in the form of a truncated pyramid with a rectangular or square base, as well as a frustoconical with a circular or oval base.
  • the tray 1, made of aluminum, optionally coated on the outside, containing the frozen food 2 is provided with a cover 3, made of material transparent to the microwave.
  • the cover 3 can be manufactured by folding or forming, for example cardboard covered with a layer of plastic material on its internal face. It can be obtained by injection or thermoforming of a plastic material or of a composite cardboard and plastic material.
  • the plastic is preferably polyethylene or polybutylene terephthalate, a polyolefin, for example polybutylene, polymethylpentene, polypropylene or high density polyethylene, polyetherimide, polystyrene, polyvinyl chloride, polycarbonate, or combinations materials.
  • the cover comprises a face 4, the rounded contours of which are adapted to those of the upper edge 5 of the tray and a continuous side wall 6 connected to the face 4.
  • this side wall follows the side wall in its beginning. 7 of the tray, so is slightly re-entrant. This configuration allows the cover to be snapped onto the tray.
  • the start of the side wall can also be substantially perpendicular to the face 4.
  • the side wall is extended by a flared skirt up to the level of the bottom of the tray. This skirt defines a sufficient enveloping volume to avoid the formation of undesirable electric arcs in the case where the metal tray is close to other metallic objects such as for example the wall of the oven or another tray, during the preparation, as it will be explained later.
  • the side wall 6 has a line of rillage 8 or perforations at the change of direction of the wall.
  • the wall 6 comprises precuts 9 or perforation lines at the angles from the rillage line 8.
  • the end of the wall defines lateral gripping ears 10 serving at the same time as flexible tongues to hold the tray in the cardboard case 11, which reduces the risk of deformation during handling.
  • the cover 3 is provided with protruding reliefs which constitute studs 12 for spacing the bottom and centering studs 13 for the tray.
  • a sheet of embossed paper capable of absorbing water is inserted between the studs 12 against the bottom of the cover. Its thickness is such that it reaches the upper level of the studs 12.
  • the cover 14 of a tray 15 with a round base includes a bottom 16 of diameter adapted to that of the upper edge of the tray.
  • the tray contains a precooked crust 17 and a sachet 18 containing a dehydrated mixture constituting the filling.
  • the tray containing the base of dough, the bag and its cover are placed in a cardboard case 19.
  • the case 19 can alternatively be replaced by a bag, for example made of polyethylene.
  • the cover comprises a continuous lateral face 20 and an edge 21, lateral face and defining edge, at two diametrically opposite points of the gripping ears 22 and providing flow conduits 23 for the water intended to be poured therein as explained above. after.
  • the cover 14 is provided towards the middle part of the bottom with bottom spacing studs 24 in the form of arcs and notches 25 of height greater than that of the studs at the level of the side wall intended for centering the tray.
  • the cover covers all of the compartments and can, once turned upside down, serve as a double boiler to cook or heat all the food contained in the different compartments.
  • the cover 26 consists of a carton 27 sealed on the inside, for example by impregnation of polyethylene.
  • the cardboard 27 is wrapped around a mattress of absorbent embossed paper 28.
  • the tabs 29 are pre-cut in the corners. This variant is suitable for heating and cooking frozen prepared meals in aluminum trays.
  • Aluminum can optionally be painted externally.
  • the legs 29 are raised, the amount of water which can be absorbed by the sheet 28 is poured, then the tray is placed between the legs. Then put the dish in the microwave. During reheating or cooking, the steam generated from the absorbed water surrounds the tray and allows a homogeneous reheating or cooking.
  • Comparative examples 1 to 3 below illustrate the performance of the packaging according to the invention (1), FIG. 1, the lid being turned over, filled with the quantity of water indicated and the tray containing the food being placed at the interior as indicated above, compared with those (2) of the aluminum tray containing the food and (3) of a special glass dish for microwave ovens in which the food is placed once removed from the mold, when heating for 12 min. various frozen ready meals using a Kenwood A414 microwave oven (460 watts returned) with turntable.
  • the product is removed from the mold, then placed in the glass utensil either after being stored for 15 min at 20 ° C, or 15 min at + 20 ° C, or directly. This additional operation is intended to study the impact of the thermal inertia of the tray on the heating of the food. The temperatures are measured as quickly as possible after the treatment in the oven is finished.
  • Comparative Example 4 the performance of the packaging according to the invention (1), FIG. 6, is compared with that of the aluminum container containing the food (2) in the preparation of a quiche with flan filling.
  • the tray has a volume of approximately 500 cm 3 .
  • the evaporation of water from the product is less in (1) than in (2) and (3), and this is particularly noticeable when the amount of water added is greater.
  • organoleptic qualities are appreciably better for (1) than for (3) whereas these are insufficient in the case of (2).
  • the packaging (1) provides a uniform temperature and less evaporation of water from the product. Whether the water added is cold or hot has no major influence on the result. Homogeneity is slightly better with cold water.
  • the temperature differences are attenuated because the fatty sauce drips into the bottom and facilitates heat transfer by convection.
  • the packaging according to the invention allows the production of products which would be impossible to prepare without it in a microwave oven. It is found in fact that, in the preparation of the sides according to (1), a rise in temperature at full power is much too rapid and causes the filling to boil before it coagulates. The result is the formation of a totally unacceptable scrambled egg-like texture.
  • the use of a reduced power, conventionally obtained in commercial household ovens by sequential emission of waves, would not make it possible to remedy this defect because it would lead to a movement of the lining detrimental to a correct coagulation of the blank: we would obtain also a scrambled egg texture.
  • the addition of a sufficient quantity of water to the upturned cover, according to (2) makes it possible to increase the load in the microwave enclosure for a fixed quantity of food. This regulates the rate of temperature rise at full power. This allows a better distribution of energy in space.
  • the water layer is mobile and provides a rapid heat transfer in comparison with the slow transfer in the more viscous medium of the lining. The effect obtained is a uniform temperature leading to correct coagulation of the blank before the filling comes to a boil.
  • the derivation by the water of the water bath of part of the microwave energy into conventional heat finally allows the heating of the precooked crust which, because it is dry, is not very sensitive to microwave radiation.
