Abstract

PROBLEM TO BE SOLVED: To provide a tray for microwave oven cooking which does not require a heat-proof plate.SOLUTION: A tray 1 for microwave oven cooking is used for cooking food by placing food on it and heating it in a microwave oven, and includes an oil absorbing uneven paper 11 on which to place food, and an oil impermeable cardboard 12 provided on the undersurface of the uneven paper 11. During cooking in the microwave oven, oil oozing from food is absorbed by the oil absorbing uneven paper 11 and accumulated in recesses in the uneven paper 11, preventing adhesion of the oozing oil to food. Furthermore, oozing oil does not ooze below the cardboard 12 due to the oil impermeable cardboard 12 and hence does not soil the microwave oven.

Description

  The present invention relates to a tray used when cooking food using a microwave oven.

In recent years, cooking such as grilled fish and fried chicken using a microwave oven has been performed. For example, Showa Sangyo Co., Ltd. sells a deep-fried deep-fried powder for cooking in a microwave oven called “Fried Flour because it is Chin in the Range”. Non-Patent Document 1 describes cooking using the fried powder in the following procedure.
1. Sprinkle the cut chicken with "boiled powder because it is tinned in the range".
2. Line up the chicken that is covered with kitchen paper and coated with “fried powder because it is tinned in the range”.
3. Heat in a microwave without wrapping.

  Since the above cooking method does not use fire or oil, it can be made easily and in a short time. Moreover, since it is not fried with oil, the calories of fried chicken can be kept low.

“Special page for fried powder because it is tinned in the range”, [online], [searched on January 21, 2009], Internet <URL: http: //www.showa-sangyo.co.jp/special/karaageko/>

  In the above cooking method, no oil is used, but the oil oozes from the chicken while being heated in the microwave. This oil is absorbed by the kitchen paper, but if the amount of oil is large, it cannot be absorbed by the kitchen paper and accumulates on the surface of the bakeware, which adheres to the deep-fried food and causes the deep-fried food after cooking to become sticky. . Moreover, since the bakeware used for cooking is soiled by the oil that oozes from the kitchen paper, it is necessary to wash the bakeware after cooking.

  The problem to be solved by the present invention is to provide a microwave cooking tray that does not require a bakeware.

The first invention made to solve the above problems is
A microwave cooking tray for cooking food by placing food and heating in a microwave oven,
Oil-absorbing uneven paper on which the food is placed;
A non-oil-permeable board provided on the lower surface of the uneven paper;
It is characterized by having.

  The microwave oven cooking tray (hereinafter referred to as “tray”) according to the first aspect of the invention is an oil-absorbing concavo-convex paper on which food is placed and an oil-impervious property provided on the lower surface (non-oil-permeable property). The oil that oozes out of food when cooking in a microwave oven is absorbed by the oil-absorbing concavo-convex paper and accumulates in the concavo-convex portion of the concavo-convex paper, so that the oozed oil adheres to the food. There is no. Furthermore, the oil so oozed does not ooze below it by the non-oil-permeable paperboard, so that the microwave oven is not soiled. Therefore, if the tray for microwave ovens according to the present invention is used, it is not necessary to use a conventional bakeware, and there is no need to wash it after use. Furthermore, the stickiness of the food after cooking is suppressed.

As the concavo-convex paper, an ordinary corrugated cardboard (core processed into a corrugated shape) or embossed paper can be used. Also, if the amount of oil that oozes from the food is large, the oil that has accumulated on the surface of the paperboard does not adhere to the food. Is preferably about 5 to 10 mm). Moreover, it is desirable that the paper quality be thick (for example, the basis weight is about 100 to 200 g / m ² ) so that oils produced by general foods can be absorbed. Paper is about 60g / m ² ).

  The uneven paper and the paperboard are preferably joined to each other. As a result, the convex part of the concavo-convex paper spreads around and falls due to the weight of the food (in the case of corrugated sheets, the peak part spreads sideways and becomes low), and the oil accumulated in the concave part (valley part) adheres to the food. Is prevented.

Further, the second invention made to solve the above problems is
A microwave cooking tray for cooking food by placing food and heating in a microwave oven,
Non-oil-permeable uneven paper on which food is placed;
A paperboard bonded to the lower surface of the uneven paper;
It is characterized by having.

  In the tray according to the second invention, the concavo-convex paper accumulates oil that oozes from the food in the recess, prevents the oil from adhering to the food, and prevents oil from leaching below it, This prevents the convex part of the uneven paper from being lowered by the weight of the food. Also with this configuration, the same effect as the tray of the first invention can be obtained. Also in the second invention, corrugated paper or embossed paper can be used as the uneven paper. For example, such a corrugated paper can be produced by covering the surface of a corrugated sheet of ordinary corrugated cardboard with a non-oil-permeable sheet such as a vinyl sheet or applying a non-oil-permeable coating.

  In the microwave oven cooking tray according to the first aspect of the present invention, oil that oozes from the food when cooking in the microwave is absorbed by the oil-absorbing uneven paper, and also accumulates in the concave portion of the uneven paper, so that the oil has oozed out. Oil does not adhere to food. Furthermore, the oil so oozed does not ooze below it by the non-oil-permeable paperboard, so that the microwave oven is not soiled. Further, in the tray according to the second invention, oil that oozes from the food is stored in the recesses of the non-oil-permeable uneven paper so that the oil does not adhere to the food and the oil oozes below it. To prevent. Therefore, if the tray for microwave ovens according to the present invention is used, it is not necessary to use a conventional bakeware, and there is no need to wash it after use.

  An example of a microwave cooking tray (hereinafter referred to as “tray”) according to the present invention will be described with reference to the drawings.

  FIG. 1 is a schematic configuration diagram of a tray 1 according to the first embodiment, where (a) is a perspective view of the tray 1 and (b) is a cross-sectional view taken along line bb. The tray 1 is composed of a corrugated plate 11 having a peak portion 11A and a trough portion 11B extending in parallel in one direction, and a flat paperboard 12, and an adhesive 13 applied to the back surface of the trough portion 11B of the corrugated plate 11. Thus, the corrugated board (uneven paper) 11 and the paper board 12 are bonded to each other. The corrugated plate 11 may be anything as long as it has oil absorbency, and other than corrugated cardboard, ordinary corrugated paper (which is not subjected to any oil repellent treatment or the like) can be used. In addition, you may use embossed paper instead of a corrugated sheet. As the paperboard 12, one having non-oil permeability is used. For example, ordinary paper that has been subjected to an oil-repellent treatment or ordinary paper that is coated with a vinyl sheet or the like can be used.

  The usage method of the tray 1 of a present Example is as follows. The food 71 is placed on the surface of the tray 1 on the corrugated plate 11 side, placed in the microwave oven 70, and heated for a predetermined time (FIG. 2).

When the oil 72 oozes out from the food (eg chicken with clothes) 71 by heating, the corrugated plate 11 of the tray 1 absorbs it (FIG. 3). Further, the oil 72 that cannot be absorbed by the corrugated sheet 11 accumulates in the valleys of the corrugated sheet 11. In any case, the oil 72 does not adhere to food.
Furthermore, since the oil 72 does not ooze below the non-oil-permeable paperboard 12, the microwave oven 70 is not soiled. Therefore, if this tray 1 is used, it is not necessary to separately use a heat-resistant dish or the like, and there is no need to wash it after use. Further, the corrugated plate 11 maintains the shape of the corrugated sheet 11 by bonding the valley 11B of the corrugated sheet 11 and the paper sheet 12 to each other. Therefore, it is prevented that the corrugated plate 11 spreads sideways (in a direction orthogonal to the direction in which the mountain portion 11A extends) due to the weight of the food 71, and the wave height is lowered.

After heating, the tray 1 is taken out from the microwave oven 70 with the food 71 placed thereon. Since the tray is made of paper, it is not heated by the microwave oven 70 and can be taken out by hand.
The tray 1 may be used as a container for the food 71 as it is, or the food 71 may be picked up from the tray 1 and placed in another container. Since the tray 1 is made of paper, it can be discarded as it is after use.

When cooking food 71 containing a lot of oil, the corrugated plate 11 has a high wave (having a height of about 5 to 10 mm) so that the oil accumulated on the surface of the paperboard 12 does not adhere to the food 71. ) Is desirable. Furthermore, it is desirable to use a thick paper (for example, a basis weight of about 100 to 200 g / m ² ).

FIG. 4 is a longitudinal sectional view of the tray 2 of the second embodiment. The shape of the tray 2 is the same as that of the above embodiment (FIG. 1).
This tray 2 is composed of a non-oil-permeable corrugated sheet 21 having a peak portion 21A and a trough portion 21B, and a flat paperboard 22, and an adhesive 23 applied to the back surface of the trough portion 21B of the corrugated sheet 21. The corrugated sheet 21 and the paperboard 22 are bonded to each other (FIG. 4 (a)).

The tray 2 is used by placing the food 71 on the surface on the side of the corrugated plate 21, placing it in the microwave oven 70, and heating it for a predetermined time, like the tray 1. Here, since the corrugated plate 21 is non-oil-permeable, the oil 72 that exudes from the food 71 during the heating in the microwave oven 70 flows on the surface of the corrugated plate 21 and accumulates in the valley portion 21B (FIG. 4B). )). Therefore, as with the tray 1, the oil 72 is prevented from adhering to the food 71. Moreover, since the oil 72 does not ooze out below the corrugated plate 21, the microwave oven 70 is not soiled.
On the other hand, since the paperboard 22 is bonded to each trough portion 21B of the corrugated sheet 21, the corrugated sheet 21 is prevented from being deformed due to the weight of the food 71 (the wave height is lowered). Therefore, the paperboard 22 does not have to be oil-permeable or oil-absorbing.

  The corrugated sheet 21 may itself be non-oil-permeable, or may be provided with a non-oil-permeable layer on the front surface or the back surface thereof.

  FIG. 5 is a perspective view showing a schematic configuration of the tray 3 of the third embodiment. The tray 3 of this embodiment is manufactured by assembling one single-cardboard blank. FIG. 6 is a development view of the blank, and a top view, a bottom view, a cc cross-sectional view, and a dd cross-section in the assembled state. The diagrams are shown in FIGS. 7 (a), (b), (c), and (d), respectively. The tray 3 according to the present embodiment is substantially box-shaped, and a V-shaped placement portion with a lower center is provided for placing food on the top. The mounting portion is constituted by two upper surface plates 31 and 32 being engaged with each other by a trapezoidal engagement piece provided at the edge thereof. In the central engagement portion, FIG. As shown in FIG. 2, since a gap is generated between the lower flat plate on the upper surface plate 32 on the upper side and the corrugated plate on the upper side of the upper surface plate 31 on the lower side, the oil that has exuded from the food passes through this gap to the tray. Falls inside 3. Below the tray 3, the four-sided pieces 34, 35, 36, and 37 are folded up to form a saucer together with the bottom plate 33, so that the oil that has dropped down in this way can come out of the tray 3. Absent.

  Since the tray 3 of the present embodiment is used in the above-described configuration, the corrugated cardboard constituting the blank (FIG. 6) only needs to have oil repellency in either one of the corrugated plate and the flat plate. In particular, it is desirable to impart oil repellency to the side of the surface on which the corrugated sheet is not attached. By doing so, it is possible to cleanly treat the oil accumulated in the tray part constituted by the bottom plate 33 and the four-sided pieces 34, 35, 36, and 37. In this embodiment, embossed paper may be used instead of the corrugated sheet.

FIG. 8 is a longitudinal sectional view (a) of the tray 4a of the fourth embodiment and a longitudinal sectional view (b) of the tray 4b of the application example. The shapes of the trays 4a and 4b are the same as those in the first embodiment (FIG. 1 (a)).
The tray 4a is obtained by attaching a heat generating sheet 41 that generates heat by absorbing microwaves from the microwave oven on the corrugated plate 11 of the tray 1 of the first embodiment.

  The heat generating sheet 41 is not particularly limited as long as it absorbs microwaves from the microwave oven and generates heat. For example, the heat generating sheet 41 includes a film layer and a conductive material layer described in JP 2011-230776 A, or a special material. A substrate obtained by forming or mixing an electromagnetic wave heat generating layer on the substrate described in Kaikai 2010-131317 can be used.

  In the tray 4a of the present embodiment, the food sheet can be burnt by providing the heat generating sheet 41. Of course, as in the tray 1 of the first embodiment (see FIG. 3), the oil that oozes out from the food during heating is absorbed by the corrugated plate 11 having oil absorption, and the oil that cannot be absorbed is the valley of the corrugated plate 11. Accumulate. Further, the oil does not ooze below the non-oil-permeable paperboard 12.

  A tray 4b, which is an application example of the tray 4a of the fourth embodiment, is obtained by further bonding the above heat generating sheet 41 with an adhesive on the corrugated plate 21 of the tray 2 of the second embodiment (FIG. 8). (b)).

  Also in the tray 4b, the food sheet can be burnt by providing the heat generating sheet 41. Of course, as with the tray 2 of the second embodiment (see FIG. 4 (b)), the oil that exudes from the food during heating flows on the surface of the non-oil-permeable corrugated sheet 21, accumulates in the valleys, and corrugated sheet 21 It doesn't go below.

FIG. 9 is a development view (a) of the microwave tray 5 of the fifth embodiment and a longitudinal sectional view (b) when the tray 5 is assembled. As shown in FIGS. 9A and 9B, the shape of the tray 5 is the same as that of the third embodiment (FIG. 6). The upper surface plates 31 and 32 are assembled in a V shape so that the center is lowered, and food is placed on the V-shaped placement portion.
This tray 5 is the same as the tray 3 of the third embodiment, in which the above heat generating sheet 41 is adhered to the corrugated plate of the two upper surface plates 31 and 32 forming the V-shaped mounting portion with an adhesive. It is affixed (FIG. 9 (a)).

  Also in this tray 5, by providing the heat generating sheet 41, it becomes possible to burn the food. Of course, as in the third embodiment, the oil that exudes from the food during heating accumulates in the saucer composed of the folded four-sided pieces 34, 35, 36, 37 and the bottom plate 33 and does not go out. Absent.

  FIG. 10 is a development view (a) of the microwave tray 6 of the sixth embodiment and a longitudinal sectional view (b) when the tray 6 is assembled. As shown in FIG. 10 (a), the developed view of the tray 6 is the same as that of the third embodiment (FIG. 6). However, as shown in FIG. Is different from the third embodiment. That is, in this embodiment, the upper plates 31 and 32 are assembled in an inverted V shape so that the center of the upper plates 31 and 32 is raised, and the food is put into the internal space A for use. For this reason, the tray 6 is assembled so that the corrugated plate faces the space A and the flat plate faces the outside.

Further, in the tray 6, the heat generating sheet 41 is adhered to the bottom plate 33 serving as the bottom surface of the space A and the corrugated plates including the top surfaces 31 and 32 serving as the top surfaces of the space A with an adhesive (FIG. 10). (a)).
The heat generating sheet 41 may be attached to at least the bottom plate 33 and the upper surface plates 31 and 32, but may be attached to the four-sided pieces 34, 35, 36, and 37.

  In the tray 6, the heating sheets 41 are provided on the upper surface and the bottom surface inside the tray, so that the upper and lower surfaces of the food can be burnt. In addition, since the tray 6 can cover the upper surface side of the food, evaporation of water in the food can be suppressed, and the food can be baked more plumply. Of course, also in the tray 6, as in the third and sixth embodiments, the oil that exudes from the food during the heating is composed of the folded four-sided pieces 34, 35, 36, and 37 and the bottom plate 33. It stays in the saucer and never goes outside.

  The trays of the above embodiments can be stored in a cylindrical shape when not in use, for example (in the case of the tray 3 in an unfolded state). Further, a plurality of sheets of material can be stored in a wound state, and can be cut out along the perforation provided for each predetermined length for each use to form a tray for use. .
