[Industrial applications]

 The present invention relates to a retort set food that can be eaten by a vending machine having a built-in microwave oven, and a container thereof.

[0002]

[Prior art]

 A wide variety of retort or frozen foods have been commercialized, and retort-set foods and bagged retort-carried foods that are bagged with boiled spaghetti and prepared sauce are generally well known. Recently, retort foods such as rice and pilaf, which do not require tableware, have been commercialized by filling and sealing a container with a plate and cooking the container with an electronic range. Further, as a food container for microwave oven cooking, a large number of food containers have been devised, in which a part of the container is shielded from microwaves by a metal foil or the like and the heating portion can be controlled. Also, if the sealed food is heated together with the container in a microwave oven, the generated vapor pressure damages the container, so that part of the seal line on the outer periphery of the container is projected inward in a V shape to form a V shape. Japanese Patent Application Laid-Open No. 2-84908 discloses a device in which the internal pressure is concentrated to automatically open. Retort or frozen food packed in a container with a plate is also considered for cooking with boiling water in addition to the adjustment by a microwave oven, and it is difficult to use a heat insulating material for the plate to shorten the cooking time with boiling water. As a result, the cooked food is hot and cannot be held in your hands, and you will have to eat it on the table.

[0003]

[Problems to be solved by the device]

 If you want to easily eat your meal in a microwave oven without polluting the kitchen, the traditional bag-packed spaghetti set food is a frying pan to sauté the spaghetti, a pot to warm the sauce and hot water, and dishes such as a plate of spaghetti. It is necessary to open the required and warm sauce bag and print it on the spaghetti. Also, as in the case of curry in a retort or frozen rice packed in a dish with a dish, when the packaged prepared side dish is cooked in a microwave oven after it is sprinkled on the rice side, the side dish does not spill the side dish. Requires sufficient capacity. Further, when different foods are cooked in a microwave oven at the same time, heating unevenness is likely to occur between the foods due to the difference in heat generation due to microwaves. For this reason, it is possible to control the heating part by shielding the microwave with a part of the container using metal foil, but in the case of rice and prepared foods that have poor fluidity, the part that does not block the microwave is extremely heated. There is a problem.

Frozen foods require refrigeration facilities in the distribution and sales processes, and therefore need to be stored in the refrigerator immediately after purchase, which causes an increase in cost, and are not suitable as foods for camping. It also has the drawback of requiring more cooking time than retort pouch foods.

Next, consider the case where a retort or frozen food is cooked and sold by an automatic vending machine having a built-in microwave oven. In this case, it is premised on food packed in a container with a dish that does not require tableware, but it is necessary to open a part of the seal lid before the internal pressure rises due to heating to avoid damage to the container due to heating of the microwave oven. Yes It would be annoying if the customer opened it by hand. For this reason, the seat lid automatic opening container disclosed in JP-A-2-84908 is required. In this case, the tension force mainly acts in the shearing direction on the V-shaped seal portion where the tension force of the seat lid is concentrated. Since it is difficult to act in the peeling direction, the internal pressure required for the opening is relatively high, and the tension of the seat lid concentrates on the V-shaped seal portion in the dish as well, so the rigidity of the dish must be increased more than necessary.

In addition, in the case of meals by a vending machine, a poor meal environment such as a standing meal or in a car is expected, and it is necessary to have meals with a plate in hand. However, since it is difficult to use heat insulating material in the dish to shorten the cooking time with hot water, meals with the dish in hand are hot and almost impossible. The present invention aims to solve the various problems described above.

[0007]

[Means for Solving the Problems]

 In order to achieve the above object, the constitutional feature of the invention according to claim 1 is that in a retort food which is sealed with a plate and a sheet lid and cooked in a microwave oven or hot water together with the container, the plate is a partition plate. It is divided into two rooms and one room is filled with boiled spaghetti and the other room is filled with cooked sauce and sealed separately.

In addition, the constitutional feature of the invention according to claim 2 is that in the retort-set food according to claim 1, the spaghetti and the cooked rice instead of the sauce and the prepared side dish are separated. It was filled and sealed.

Further, the structural feature of the invention according to claim 3 is that, in the retort-set food container according to claim 1 or 2, a plate portion or a sheet lid that constitutes one of the chambers. Or, both of them are coated with non-microwave particles in a dotted or meshed manner.

Further, the constitutional feature of the invention according to claim 4 is that in a food container which is sealed with a plate and a sheet lid and cooked together with a microwave oven or hot water, the folded back portion is folded at the center of the sheet lid. This is because the pressure reducing port is provided at the center of the apex of the folded portion and the circumference is sealed.

Further, the structural feature of the invention according to claim 5 is that in a dish of a food container which is sealed by a dish and a sheet lid and can be cooked together with a microwave oven or boiling water by vacuum forming or pressure forming. The flange shape is integrally provided on the entire circumference of the bottom part or a part thereof.

[0012]

[Operation and effect of the device]

 In the device according to claim 1 configured as described above, it is sufficient to heat the set food of spaghetti and sauce together with the container in a microwave oven or boiling water when cooking, and at the time of meal, peel the sheet lid and use the fork to cook the spaghetti. After loosening, you can scrape the sauce on the spaghetti side and eat it each time. For this reason, you do not need a frying pan to fry the spaghetti, a pot to heat the sauce and hot water, and dishes to put the spaghetti on, like the conventional bag-filled spaghetti set food, and open the warm sauce bag to open the spaghetti No need to squeeze out. Since cooking can be done easily in this way, it can be cooked and sold by a vending machine with a built-in microwave oven.

Further, in the invention according to claim 2 configured as described above, at the time of cooking, it is sufficient to heat the set food of rice and side dish together with the container in a microwave oven or boiling water. Peel off chopsticks or spoon to loosen the rice and then eat. The present invention is suitable for sauce-like side dishes such as curry, and when cooking in a microwave oven like the conventional combination of bag-filled curry and plate-filled rice, remove the sheet lid of the rice in advance. There is no need to open and squeeze a bag of curry, nor does it need a sufficient capacity to prevent the curry from spilling into the rice container. Since it is a retort food, it does not need to be refrigerated like frozen food and does not require much cooking time. Since cooking can be done easily in this way, it can be cooked and sold by a vending machine with a built-in microwave oven.

Further, in the invention according to claim 3 configured as described above, since the microwave impermeable particles are scattered or mesh-shaped coated on the container, By adjusting the density, it is possible to control the amount of passing microwaves per unit area of the container. By applying this coating to only one of the chambers having two chambers, it is possible to produce containers with different microwave transmission rates in each chamber. That is, in a set food product in which two food products having different microwave exothermic properties are separately filled and sealed, the two food products can be heated uniformly or at a temperature suitable for the meal of each food product. According to the present invention, there is no heating unevenness in the case of a food having poor fluidity as compared with the conventional method of completely blocking microwaves in a part of the container.

Further, in the invention according to claim 4 configured as described above, when cooking in a microwave oven with the container sealed, the internal pressure of the food container rises due to heating of the microwave oven, but Since the pulling force of the seat lid is concentrated on the pressure reducing port sealing portion provided in the folded portion, the sealing portion is easily peeled off, and water vapor inside the container is discharged from the pressure reducing port of the sheet lid, so that the container can be prevented from being damaged. This eliminates the need to manually open a portion of the seat lid before cooking in the microwave. Also, when cooking with an automatic vending machine with a built-in microwave oven, it is possible to cook without having to get food. In the present invention, as compared with the conventional automatic container with a seat lid, the pulling force of the seat lid mainly acts on the decompression port seal portion in the peeling direction, so that the decompression port seal portion can be peeled off with a relatively low internal pressure. Since the pulling force of the seat lid acts evenly on the outer periphery of the dish, it is not necessary to increase the rigidity of the dish.

Further, in the invention according to claim 5 configured as described above, after the container is cooked, the flange-shaped tip portion provided on the outer periphery of the bottom of the dish is touched by hand without directly touching the high temperature portion of the dish body. You can take it with you to eat. In addition, since no heat insulating material is used for the dishes, cooking time with boiling water is short. If meals can be held with the plate in this way, it is possible to eat even in a poor meal environment such as a stand-up meal expected when cooked with a vending machine with a built-in microwave oven and purchased.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. 1 and 2 are a perspective view of a spaghetti retort-set food product to which the present invention is applied and a perspective view with a sheet lid 20 removed. The container 1 is composed of a plate 10 and a sheet lid 20, and the spaghetti 2 boiled and the cooked sauce 3 are separately filled and sealed by a seal line 4. Further, since the sauce 3 is more easily heated by microwaves than the spaghetti 2, the portion of the seat lid 20 filled with the sauce 3 and the chamber 12 are made of aluminum that does not pass microwaves such as aluminum powder, as shown in FIG. The particles 5 are coated so as to be scattered. The coating pattern is not limited to dots, but may be a mesh or any pattern.

The dish 10 has chambers 11 and 12 in which the spaghetti 2 and the sauce 3 are filled by the partition portion 13, and is integrally formed by vacuum forming or pressure forming. Further, two flange shapes 14 facing each other are integrally formed on the outer periphery of the bottom of the chamber 11. 3 and 4 are a cross-sectional view of the container 1 in a state of being held in the hand and a cross-sectional view in which the flange shape 14 is enlarged. As shown in FIG. 3, even if the container 1 is held by hand, it does not directly touch the high temperature part of the dish body after cooking. In the flange shape 14 of FIG. 4, the tip is left in the shape of a ball and the heat welding portion 15 is provided at the base portion, but all may be heat welded, and the flange shape 14 may be facing downward.

As shown in FIG. 1, the seat lid 20 has a folded-back portion 21 that extends over the chambers 11 and 12 in the center, and a decompression port 22 and a seal line that closes the depressurized opening 22 at the apex of the folded-back portion 21. 23 is provided so as to be located at the center of each of the rooms 11 and 12. FIG. 5 shows an enlarged cross-sectional view of the decompression port 22 provided in the folded portion 21. As shown in FIG. 5, the tensile force acting on the seat lid 20 acts on the seal line 23 in the peeling direction. In addition, since the portion of the folded-back portion 21 that overlaps the seal line 4 is sealed, the food does not leak out of the container 1 or the food is not mixed with each other. Further, a seal 24 is attached to the sheet lid 20, and if the seal 24 is peeled from the sheet lid 20 after cooking and attached to the decompression port 22 to close it, the contents of the container will not spill when carried. Further, since the container 1 is equipped with a fork (not shown), no tableware is required for meals.

According to the present invention, as described above, the spaghetti and the sauce are separately filled and sealed in one dish-equipped container, and the whole container can be cooked in either the microwave oven or the hot water, and the sheet can be cooked. If you remove the lid, you can eat immediately. In other words, when cooking in the microwave oven, which is the easiest method, you do not need a frying pan to fry the spaghetti, a pot to heat the sauce and hot water, and dishes such as a plate to sprinkle the spaghetti, as compared to the conventional bag-filled spaghetti set food, and There is no need to open the warm sauce bag and squeeze it over the spaghetti.

In addition, when cooking in a microwave oven, microwave-impermeable particles are coated on the container on the source side that is easily heated, so if you heat for a certain period of time, you can eat spaghetti and sauce. Can be heated to a temperature of. Further, since the sheet lid automatic opening container is adopted, it is not necessary to manually open a part of the sheet lid in advance. Also, in an automatic seat lid lid opening container that utilizes the rise in the internal pressure of the container due to heating, the pulling force of the sheet lid against the decompression port seal part of the sheet lid mainly acts in the peeling direction, so that the internal pressure is relatively low. The decompression port seal can be peeled off, and the tensile force of the sheet lid acts evenly on the outer periphery of the dish, so there is no need to increase the rigidity of the dish. In addition, a flange shape is provided on the outer periphery of the bottom of the dish so that the dish does not come into direct contact with the hot portion of the dish after cooking even if the dish is held by hand from below. For this reason, it is possible to eat with the plate in hand. Moreover, the present invention is most effective when cooking and purchasing at a vending machine with a built-in microwave oven. That is, the customer can automatically obtain the cooked spaghetti by inserting cash and pressing the desired product button, and the warm spaghetti after cooking even in a poor meal environment such as standing or in a car. It becomes possible to eat with food in hand. In addition, since no heat insulating material is used for the dishes, cooking time with hot water is short. Further, the present invention is not limited to spaghetti, and can be applied to curry rice, beef bowl, oyakodon, Chinese rice bowl, etc.
