  According to the conventional foods, containers, and the like as described above, the foods of Patent Document 1 require that the foods to be accommodated and supported in the upper part of the container are aggregated and solidified as a whole. The trouble is troublesome. In the food / container of Patent Document 2, there is no liquid material such as soup and juice, and the steam generated from the food is discharged to the outside during heating. Is unsuitable. In the container / food of Patent Document 3, the seasoning liquid in the bag that breaks due to an increase in internal pressure may remain in the bag, and a sufficient seasoning action may not be obtained. May be soiled. In the container of Patent Document 4, food is placed on the rice just before heating, but it is not suitable for packaging and cooking of food with liquid materials such as soup and soup. In the sheet material of Patent Document 5, a predetermined amount of seasoning liquid is supplied to the main food by being melted by heating, and even if the main food can be seasoned, a sufficient amount of liquid is required to make the cooked product mainly liquid. Cannot supply.

  In any of these cases, the container itself becomes hot by being heated in a microwave oven. Therefore, in order to insulate the container itself as a substitute for tableware, the container wall is thickened, For example, it is generally formed of a foamable synthetic resin material having high properties. However, since these heat insulating materials are opaque, it is difficult to visually recognize the food stored inside the container body from the outside, and the upper part of the stored food can be seen even if the lid is formed of a transparent resin. However, there was also a lack of appeal for products at sales places such as convenience stores and supermarkets.

  Furthermore, in the case of noodles that are prepared with a lot of liquid products such as soup and soup, it is often cooked by pouring boiling water separately prepared, and it is troublesome to prepare boiling water each time. But there is.

  Moreover, in order to be able to eat various solid foods together with soups, soups, etc., if these are collected and stored in a container, for example, the density of ingredients, particularly meat and vegetables, etc. put in the soup is high Things are not only difficult to warm up, but also become dull due to being immersed in a liquid material, which may impair the flavor.

  Therefore, the present invention has been devised in view of various circumstances that existed in the past, such as a seasoning liquid contained in a container even if it is a cooked product having a relatively large amount of liquid such as soup and soup, It can be a so-called complete meal type food container that can cook food only by heating with a microwave oven, and even after being cooked, it is insulated and held as it is as a substitute for tableware. In addition, the flavor of food such as stored ingredients is not impaired, and the stored amount of seasoning liquid, food such as ingredients can be seen from outside, even at the time of display sale An object of the present invention is to provide a food packaging container for heating a microwave oven that can sufficiently obtain a product appealing power.

In order to solve the above-described problems, in the present invention, a description will be given with reference numerals in the form for carrying out the invention to be described later. Lower storage for storing the seasoning liquid S dissolved by heating A container formed of a material that can be seen through, with a portion 2 provided in the lower portion and an upper storage portion 6 that stores and holds the food F to be cooked and provided in the upper portion through the placement step portion 4. Covering the main body 1 and the outer periphery of the lower storage portion 2 by forming a heat insulating gap, covering the heat insulating body 10 formed of a material that allows the inside of the container main body 1 to be seen through, and the opening of the container main body 1. It is characterized by comprising a lid body 30.
The heat insulator 10 has a fitting edge 11 fitted on the outer side of the fitting protrusion 3 formed in a protruding shape on the outer side of the upper edge of the lower storage part 2, and between the outer peripheral surface of the lower storage part 2. In order to set a heat insulation gap, the peripheral wall can be provided with a holding part 12 formed in a corrugated shape.
Further, the upper storage portion 6 can be configured so that an inner tray body 20 that is placed and supported on the mounting step portion 4 and stores a predetermined food F can be housed therein. The bottom plate 21 of the body 20 can be configured as having a steam introduction hole 22 formed therein.
The intermediate dish body 20 can be provided with a knob 24 that protrudes above the intermediate dish body 20, and the knob 24 has a bottom plate 21 and a part of the peripheral side wall 23 formed on the periphery of the bottom plate 21. It can be configured to bulge in a hollow shape inward and upward and to be arranged in pairs.
The lid 30 includes a fitting groove 31 formed on the peripheral edge along the inner edge of the opening so as to be forcibly fitted into the opening of the container main body 1, and a cover portion continuous to the inner edge wall of the fitting groove 31. 32 and a steam outlet valve 33 formed on the cover portion 32 so as to be undulating can be provided.

In the food packaging container for microwave oven heating according to the present invention configured as described above, the seasoning liquid S is stored in the lower storage part 2 of the container body 1 and the food F or the like is stored and stored in the upper storage part 6. In this case, the lid 30 is wrapped and wrapped so that it can be displayed and sold at a store or the like, and heated by a microwave oven or the like so that it can be eaten. Upon heating with a microwave oven or the like, the seasoning liquid S is heated and dissolved to be liquefied, and the food F is cooked directly and sufficiently separately from the seasoning liquid S, and the seasoning liquid S and food F are combined in the lower storage unit 2. Then, for example, it is cooked as a soup pasta, soup curry rice, uncle, miscellaneous cooking, stew, etc. and eaten.
The loading step section 4 partitions the lower storage section 2 and the upper storage section 6 and, for example, the rice food F solidified into a disk lump is placed and supported as it is, and the seasoning liquid S heated and dissolved, etc. Also cook as a miscellaneous meal. The intermediate dish 20 containing the food F such as vegetables, meat chunks, noodles / pasta, and cooked rice is placed and held on the placing step 4 as it is, and separated from the seasoning liquid S to hold the food F. Thus, cooking by the microwave oven or the like is efficiently cooked, and the food F and seasoning liquid S can be eaten individually or in combination by taking them out from the container body 1.
The steam introduction hole 22 opened in the bottom plate 21 of the middle dish body 20 steams and cooks the food F stored in the middle dish body 20 with steam from the seasoning liquid S generated during heating and melting, and these foods. F is transferred from the middle dish 20 to the seasoning liquid S at the time of eating, and is fed as a noodle / pasta dish, stew or the like.
The heat insulator 10 fitted so as to cover the lower storage part 2 makes the inside of the lower storage part 2 transparent so that the seasoning liquid S stored in the lower storage part 2 can be visually recognized from the outside. The product appeal at the time of sales is increased, and the heat inside the container body 1 is not transmitted to the outside by the heat insulating body 10 at the time of eating. Insulate etc.
The picking portion 24 of the middle dish body 20 picks up various foods F in the cooked middle dish body 20 from the container body 1 with fingers or the like, and takes them out into the seasoning liquid S after heating. Can be easily transferred and introduced.
The lid 30 is fitted inside the opening of the container main body 1 by the fitting groove 31 to seal the inside of the container main body 1, and the vapor generated from the seasoning liquid S during heating is further absorbed in the container main body 1. By sufficiently convection in the middle dish 20 to make steaming cooking more efficient, the steam outlet valve 33 smoothly discharges excessive steam pressure to the outside.

  Since this device is configured as described above, the seasoning liquid S, food F, and the like contained in the container are stored in a microwave oven even if the product is relatively large in liquid products such as soup and soup. It can be cooked only by heating. For example, soup pasta, miscellaneous cooking, stew, noodle dishes, and the like can be packaged in a so-called one-meal-complete food packaging container for various cooked foods. Further, even if the container body 1 itself becomes hot after cooking with a microwave oven, it is not transmitted to the outside by the heat insulator 10 and can be gripped with fingers or the like as it is, and the inside of the container body 1 is kept warm. You can eat as it is as a substitute for tableware. Furthermore, since the food F is stored and held separately from the seasoning liquid S, the flavor of the food F is not impaired by the moisture of the seasoning liquid S, etc., and is efficiently cooked directly by cooking. You can eat deliciously in the warmed state. Not only that, it is possible to see the stored amount of seasoning liquid S, food F such as ingredients, etc. from the outside of the container. It can be used for promotion.

  That is, in this device, a lower storage portion 2 for storing the seasoning liquid S to be heated and dissolved, and an upper storage portion 6 for storing and holding the food F to be cooked are provided via the mounting step portion 4. A container body 1 made of a material whose inside can be seen through, a heat insulating body 10 that covers the outer periphery of the lower storage portion 2 by forming a heat insulation gap, and allows the inside of the container body 1 to be seen through; This is because it includes a lid 30 that covers and covers the portion. As a result, cooking of the food F separated from the heated / dissolved seasoning liquid S can be obtained, so that it can be used as a cooking product container having a relatively large amount of the seasoning liquid S, and is also insulated after cooking and heating. As a result, it is possible to grab and eat with fingers as a substitute for tableware.

  In addition to the seasoning liquid S that is heated and dissolved by the lower stage storage section 2 and the upper stage storage section 6 that defines the upper upper storage section 6 in the container body 1, for example, solidified rice Can be stored and held as food F, and even the food F that cannot be solidified in a state where vegetables, meat chunks, and the like are collected can be held in the container body 1 by temporarily storing the food F in the intermediate dish 20. Moreover, since it is separated from the seasoning liquid S, it can be heated directly and efficiently by heating with a microwave oven or the like. For example, meat, vegetables, etc. with high density can be easily heated, and it can be swollen with moisture of the seasoning liquid S. And the flavor is not impaired.

  Since the steam introduction hole 22 is opened in the middle dish body 20, the food F in the middle dish body 20 is steamed and cooked by the steam generated from the seasoning liquid S during heating, and appropriate moisture is provided. When given, it becomes delicious and can be eaten.

  Since the middle dish body 20 is provided with the knob 24, after cooking, the food F stored in the middle dish body 20 is taken out from the container body 1 and is melted after the middle dish body 20 is heated by tilting. In addition, the picking portion 24 is a hollow shape formed by bulging the bottom plate 21 and the peripheral side wall 23 of the intermediate dish body 20, so that it can be moved with fingers or the like. It can be easily picked and does not cause burns.

  The outer periphery of the lower storage portion 2 is covered with a heat insulating body 10, and the heat insulating body 10 includes a holding portion 12 whose peripheral side wall is formed in a corrugated shape so as to set a heat insulating gap on the outer periphery of the lower storage portion 2. Since it is provided, even if the container main body 1 is hot after cooking, it can be gripped as it is with fingers by the heat insulator 10, and the container main body 1 can be eaten as it is as a substitute for tableware. In addition, the inside of the container main body 1 can be maintained in an appropriate temperature maintaining state, and the taste of the seasoning liquid S, food F, etc. can be further enhanced. Moreover, since the heat insulator 10 itself has a heat insulating effect on the container main body 1 and the inside of the container main body 1 can be seen through, the seasoning liquid S and the like contained in the container main body 1 can be seen as it is from the outside. For example, it is possible to increase the appeal of products at the time of display sales and use it for sales promotion.

  Since the lid 30 includes the fitting groove 31 for forcibly fitting into the opening of the container main body 1, the inside of the container main body 1 can be maintained in a sealed state, and the steam generated from the seasoning liquid S during cooking is stored in the container main body 1. Convection in the inner dish 20 and the steaming action of the food F or the like by the steam can be made sufficiently efficient, and even if the steam pressure becomes excessive, the steam outlet valve 33 smoothly smoothes the outside. It can also be discharged safely.

  In addition, the code | symbol attached | subjected in each of the means for solving said subject, and the item of the effect of an invention was attached | subjected in order to make easy reference with the part which shows each structure part described in drawing. The present invention is not limited to the structure and shape shown by these descriptions and reference numerals in the drawings.

  DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment for carrying out the present invention will be described below with reference to the drawings. Reference numeral 1 shown in the figure is a container body having a box shape with an open top, for example, gelatin that is dissolved by heating. A lower storage portion 2 in which a predetermined amount of soup, juice, roux and other seasoning liquid S formed into a semi-solid / viscous liquid with potato starch etc. is stored, and a mounting step portion 4 on the lower storage portion 2 The upper storage portion 6 in which the food F such as cooked rice or the like, which will be described later, is housed and held in an interior shape by being made larger in diameter than the lower storage portion 2 via With. The container body 1 is integrally formed of a transparent material such as PP-C (polypropylene resin) so that the seasoning liquid S and the like stored therein can be visually recognized from the outside. In addition, the seasoning liquid S should just be made into the thing of predetermined capacity | capacitance, and it is hardened so that it may not leak from the upper stage accommodating part 6, even if the container main body 1 which accommodates this is inclined.

  As shown in FIG. 3, the mounting stage 4 that divides the lower storage part 2 and the upper storage part 6 has an appropriate width along the inner and outer directions in the plane of the container body 1, and the upper storage part The food F or the inner dish body 20 placed on 6 is supported in a stable state without rattling. And it has the support edge 5 formed a little wider by making it travel inward partially as needed.

  Further, the lower storage portion 2 is fitted with a box-shaped heat insulator 10 that covers the lower storage portion 2 with a predetermined heat insulation gap formed on the outer periphery and bottom surface of the lower storage portion 2. This heat insulating body 10 has a fitting edge 11 on the upper side that fits even slightly forcibly outside the small-width fitting protrusion 3 formed in a protruding shape on the outside of the upper edge of the lower storage portion 2. Since the side wall is formed in a corrugated shape, the holding portion 12 is provided in which a heat-insulating gap having a predetermined width is set with the outer peripheral surface of the lower storage portion 2. The heat insulator 10 covers the lower storage portion 2 so that the heat inside the container body 1 is not transmitted to the outside so that the heat insulator 10 can be directly gripped with a finger or the like, and the container body 1 is heated. It is also possible to obtain a heat retaining action that maintains the temperature. In addition, this heat insulation body 10 itself is integrally formed, for example with PP-C (polypropylene resin) which is effective with the container main body 1. FIG.

  The fitting protrusions 3 are arranged at appropriate intervals on the outer side of the upper edge of the lower storage part 2 so that the outer periphery and the outer edge of the lower storage part 2 are similarly arranged along the outer peripheral edge of the lower storage part 2. In the example shown in the figure, three are provided between the three support edges 5 formed at equal intervals. The fitting edge 11 is formed in a stepped shape having a depth corresponding to the depth of the fitting protrusion 3, and the lower edge storage portion 2 is formed by fitting the fitting edge 11 to the fitting protrusion 3. The heat insulator 10 can be fitted together so as to cover. Further, by forming a gap between the fitting protrusions 3 that are arranged in a distributed manner, it is useful for raising and discharging the hot air in the heat insulating gap generated between the outer periphery of the lower storage part 2 and the holding part 12. You can also When the heat insulator 10 is fitted into the lower storage portion 2, a slight gap is set between the inner surface of the bottom portion of the heat insulator 10 and the outer surface of the bottom portion of the lower storage portion 2.

  The intermediate dish 20 is placed and supported on the placement step 4 in the container main body 1 so as to be fitted and stored in the upper storage 6, and the periphery is placed on the placement step 4. A peripheral side wall 23 is integrally formed in a standing leg shape on the periphery of the bottom plate 21 serving as a mounting edge portion to be mounted on, and is formed in a shallow box shape. Various ingredients to be put in the seasoning liquid S, for example, cooked vegetables, meat chunks, pasta, noodles, cooked rice and the like can be stored in the inner dish 20 in a state separated from the seasoning liquid S. In the heating by such as, it is possible to efficiently heat and warm, and it can be eaten separately from the seasoning liquid S. The inner dish 20 is integrally formed of a sheet-like synthetic resin material such as PPF (polypropylene film resin) as milky white, for example.

  As shown in the figure, a steam introduction hole 22 is opened in the bottom plate 21 of the inner tray body 20, and a knob 24 that slightly protrudes above the peripheral side wall 23 is formed on the peripheral side wall 23. .

  The steam introduction hole 22 introduces, for example, steam generated from the seasoning liquid S accommodated in the lower storage portion 2 into the intermediate dish body 20, and the food F stored in the intermediate dish body 20, for example, a half-cooked vegetable In addition, steam is supplied to meat chunks, pasta, noodles and other by-products, ingredients, etc. so that a steaming action can be imparted.

  The knob 24 is formed by bulging the peripheral side wall 23 and the bottom plate 21 in a hollow shape toward the inner and upper sides of the middle dish body 20 at positions facing each other along the radial direction. It is provided by arranging in a pair at the position. By picking up the picking portion 24 directly with fingers or the like, the middle dish body 20 itself can be extracted from the upper storage portion 6 and lifted, and can be eaten separately from the seasoning liquid S. The stored food F or the like is transferred into the seasoning liquid S stored in the lower storage section 2 so that the supply can be made.

  In addition, since the inside of the knob | pick part 24 is hollow shape, the knob | pick part 24 itself is not heated also with the vapor | steam from the lower stage accommodating part 2, and it picks with a finger | toe etc. and handling becomes easy. A locking edge 25 is formed on the upper edge of the peripheral side wall 23 that is an opening portion of the intermediate dish body 20 and is locked to the closing step portion 7 formed in a step shape on the opening edge of the container body 1. In addition, the middle dish 20 itself is reinforced in consideration of the load resistance of the food F stored.

  The container body 1 is covered with a lid body 30 that covers the opening. The lid 30 is closed by an inner lid structure that is forcibly fitted into the closing step 7 at the edge of the opening of the container body 1, so that further sealing can be secured. That is, the lid 30 has a fitting groove 31 formed on the periphery of the lid 30 itself along the inner edge of the opening so as to be forcibly fitted into the opening of the container body 1, and the fitting groove 31. A cover portion 32 that covers the upper portion of the knob portion 24 and a steam outlet valve 33 that can be raised and lowered on the cover portion 32, and has the same effect as the container body 1, for example. PP-C (polypropylene resin) is integrally formed.

  In addition, although the container main body 1, the heat insulating body 10, the intermediate dish body 20, the lid body 30 and the like in the illustrated example are all formed in a substantially circular shape when viewed from the plane, the present invention is not limited to this. It can also be formed into an oval, rectangular or other polygonal shape, and the size on the plane, the height and depth on the side, etc., corresponding to the amount of storage and storage of the seasoning liquid S and food F to be cooked and heated, etc. Settings can be adjusted arbitrarily.

  Next, for example, in the case of uncle or miscellaneous cooking, a predetermined amount of seasoning liquid S that is semi-solidified with gelatin or the like is stored in the lower storage 2 of the container body 1 and cooked with rice. Then, for example, a predetermined amount of food F such as cooked rice solidified in a disk lump form by gelatin or the like is placed on the placing step portion 4, covered and packaged by the lid 30, and displayed and sold. If necessary, a film may be interposed between the seasoning liquid S and the cooked rice and removed during cooking. When cooking with a microwave oven, the seasoning liquid S is heated and dissolved in a liquid state, and at the same time, the solidified cooked rice itself placed on the placing step part 4 is heated, and further from the seasoning liquid S. It is also loosened by the steam and mixed in the seasoning liquid S to become a miscellaneous meal.

  In addition, cooked vegetables, meat chunks, noodles / pastas, etc., cut to an appropriate size are stored in the intermediate dish body 20, and the intermediate dish body 20 containing these is stored in a similar predetermined amount of seasoning liquid S. Is placed on the mounting stage 4 of the container body 1 accommodated in the lower storage part 2 and similarly covered, packaged, and displayed for sale. By combining with the seasoning liquid S that has been heated and dissolved by heating, it becomes stew, soup pasta, soup curry rice or the like.

  In this way, it is possible to cope with various cooked items of microwave heating by selecting whether or not the middle dish body 20 is used, whether or not the steam introduction hole 22 is opened, selection of the seasoning liquid S, selection of the food F, and the like, Moreover, since the seasoning liquid S and the food F are separated until cooking, the food material is not changed or the taste is not lowered by being immersed in the seasoning liquid S.
