BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a food package for cooking which can be reheated and cooked in a microwave oven or a steamer while the food (packaged object) is packaged.

[0002]

2. Description of the Related Art Conventionally, for example, in the case of reheating a commercial cooked rice food product (rice ball, etc.) while it is packaged, a microwave oven or a dedicated steamer is used, and the package is a moisture-permeable film and It was composed of a polymer sheet and a water-absorbent sheet made of a non-woven fabric or the like capable of absorbing water vapor generated on the inner surface. When the food is to be re-cooked, it is only necessary to store the food packaged in the package inside the microwave oven or the like and heat it.

[0003]

However, since the inner surface of the package is an opaque sheet such as a nonwoven fabric, the cooked state can be seen not only during cooking but also after cooking unless the package is opened. Not possible, especially in commercially available baked rice balls, etc., it is difficult to repackage if the packaging is once opened, and in some cases it is impossible, whether the state after cooking is good or bad, If there is no choice but to open the package once to make a judgment, and if the cooking time is insufficient, repackage it using the package again or use another package and reheat and cook again. I had no choice but to take measures.

For this reason, repacking is time-consuming and not only inefficient, but also the cooking state varies, and water is evaporated more than necessary, which may lead to deterioration of food quality. .

The present invention has been made in view of the above problems, and it is a package for a processed cooked rice food or the like, which can be cooked while the packaged object is packaged, and during or immediately after the cooking. An object of the present invention is to provide a food package for heating and cooking, which enables visual inspection of the package.

[0006]

[Means for Solving the Problems] The technical means taken by the present invention to solve the above-mentioned problems are a transparent moisture-permeable film sheet 3 and an oil-absorbing / water-absorbing material provided on the inner surface 4 of the film sheet 3. The oil-absorbent and water-absorbent sheet 6 is provided with a window portion 7 so that the packaged object 1 can be inspected.

A non-woven fabric is used as the oil / water absorbent sheet 6.

[0008]

[Function] Since the food package for cooking according to the present invention is composed of the transparent moisture-permeable film sheet 3 and the oil-absorptive and water-absorbing sheet 6, the film sheet 3 has the original packaging function (protection of food). , Improve handling, promote sales, etc.), especially when using a microwave oven, absorb microwaves generated and accelerate heating of food 1. Further, since the film sheet 3 is moisture permeable, water vapor generated when the food 1 is heated can be released to the outside.

On the other hand, since the oil-absorbent and water-absorbent sheet 6 absorbs evaporated water and oil components generated from the food 1 when heated, the food 1 does not become sticky and spoil the taste, and the food 1 does not have freshness or a product. Value can be maintained.

Further, the oil-absorptive and water-absorbing sheet 6 is provided with a window portion 7 in a part thereof, and only that portion serves as an envelope of the transparent film sheet 3, so that from the top of the package. The cooked state of the food 1 stored inside can be inspected. Therefore, the food 1 can always be suitably cooked while being packaged.

[0011]

[Examples] Commercially available cooked rice food 1 (herein, a grilled rice ball will be described as an example) is preferably packaged and reheated using a microwave oven or a dedicated steamer. An example of the above-mentioned food package for heating and cooking will be described with reference to the drawings.

As shown in FIGS. 1 and 2, the package body 2 according to the present invention is heat-sealed to the transparent moisture-permeable film sheet 3 and the peripheral edge 5 on the inner surface 4 side of the film sheet 3. The oil-absorptive and water-absorbent sheet 6 is formed on the oil-absorptive and water-absorbent sheet 6, and the window portion 7 is cut out in a circular shape so that the cooked state of the baked rice ball 1 which is the packaged object can be inspected.
Is provided.

In the package having the above-mentioned structure, processed foods such as baked rice ball 1 are packaged as shown in the front view of FIG. 3 and the rear view of FIG. That is, the baked rice ball 1 is placed in the orthogonal direction along the central portion in the longitudinal direction of the oil-absorptive and water-absorbing sheet 5 provided on the inner surface 4 side of the package body 2, and first, one side of the package body 2 is placed. Then, one side of the rice ball 1 is surrounded, and then the other piece of the packaging body 2 is bent inward along the peripheral side surface of the rice ball 1 to surround the entire rice ball 1 and one end of the other piece. The edge portion 8 is attached and fixed to the surface of one side of the package body 2 so as to be freely separable with an adhesive or the like, and is sealed.

Incidentally, an opening means such as two cuts 9 and 9 is provided at one widthwise central end of the package body 2 so that the package can be easily opened when eating the rice ball 1. ing.

The moisture permeable film sheet 3 is made of polyethylene, polypropylene, or the like, which is made by containing a polyamide synthetic resin, an inorganic filler such as calcium carbonate, or by blending and kneading and dispersing an incompatible resin. A microporous film or the like obtained by stretching a polyolefin-based resin into a sheet shape is used, and the surface thereof is provided with a display or a print for decoration, if necessary.

Further, as the oil / water absorbent sheet 6,
Nonwoven fabrics made of various raw material fibers coated with a heat-fusible resin are used.

Next, a case will be described in which the baked rice ball 1 packaged with the package constructed as described above is reheated (reheat cooking) using, for example, a microwave oven immediately before eating.

First, after storing the packed rice ball 1 in the microwave oven, the microwave oven is operated. Then, microwaves generated from the microwave oven are absorbed into the baked rice ball 1 through the moisture-permeable film sheet 3 and the nonwoven fabric (oil-absorptive water-absorbent sheet 6) of the package body 2, and the baked rice ball 1 is absorbed from inside. Be heated.
At the time of this heating, steam is generated from the baked rice ball 1, and the steam is absorbed and absorbed by the nonwoven fabric 6.

Moreover, since the moisture absorbed by the non-woven fabric 6 is retained, the moisture does not return to the roasted rice ball 1 until the non-woven fabric 6 becomes saturated, and the roasted rice ball 1 may become watery. There is no.

Also, the evaporated moisture which is not absorbed by the nonwoven fabric 6 is appropriately discharged and diffused to the outside due to the moisture permeability of the film sheet 3 provided in the upper layer, so that dew condensation may occur in the package body 2. Nothing happens, and grilled rice ball 1 is not sticky.

Further, for example, if the rice ball 1 is baked by using the oil component for the first processing, the oil component and the like may appear from the rice ball 1 during the heating, but the nonwoven fabric 6 is Since the oil component is also absorbed and sucked, the surface of the baked rice ball 1 does not become watery or oiled, and the rice is cooked in a fluffy state without damaging the taste.

In the reheating cooking, the nonwoven fabric 6 of the packaging body is provided with a window portion 7 cut out in a circular shape so that the cooked state can be inspected, and the film sheet 3 provided on the upper layer thereof is provided. Since it is transparent, it is possible to see the cooking state of the internal rice ball 1 inside the package while it is still wrapped in the packaging after the set cooking time.
Judging from the water vapor and the like released on the inner surface 4 of the film sheet 3 corresponding to 7, it is possible to always perform suitable heating and cooking.

As shown in FIG. 5, the window 7 may be provided along the widthwise center line of the package main body 2 by a certain width. A single sheet may be used, and the film sheet 3 may be appropriately heat-welded in accordance with both ends in the width direction. In addition, the window 7 may be appropriately provided at a position where the food 1 can be seen after the food 1 is packaged, and the shape thereof is not particularly limited.

The oil-absorbent and water-absorbent sheet 6 may be made of non-woven fabric and may be provided with a water-absorbent layer made of a water-absorbent polymer, for example. You can use any kind of food.

Further, the heat-sealing of the moisture-permeable film sheet 3 and the oil-absorptive water-absorbing sheet 6 is not limited to the entire peripheral edge portion 5,
As shown in FIG. 5, it is preferable that the both ends in the longitudinal direction are not heat-bonded but partially heat-bonded in the form of vertical stripes, because the release and diffusion of moisture to the outside becomes effective.

The present invention is not limited to the above embodiment, and the shape of the package body 2 can be arbitrarily changed according to the type of the food 1, and the packaged object can be the above-mentioned baked rice ball. Not only is it effective in various cooked foods.
