Description

  The present invention relates to a microwave oven and a microwave oven integrated food.

  When cooking food and drink such as chilled foods and frozen foods that contain a lot of liquid and a lot of viscous ingredients such as soup, risotto, ramen, etc., so-called hot pots using a heating cooker such as an electric stove or gas stove It is common to cook and cook. Since these heating cookers can adjust the amount of heat, they can be cooked while controlling the rise of bubbles so that the liquid portion does not spill during boiling cooking.

  On the other hand, in microwave cooking, it is difficult to adjust the amount of heat at any time, so the liquid part of food and drink rises as a bubble while holding solids with boiling, from the container opening When the height is too high, there are problems such as spilling out of the container, and large bubbles generated by bumping burst, and the liquid portion of the food and drink is scattered outside the container, causing the inside of the microwave oven to become dirty. Therefore, in order to prevent spilling and scattering, it is necessary to shorten the cooking time or repeatedly heat and cook in a range where spillage does not occur, so there was a problem that sufficient cooking could not be done and it took time and effort .

  In order to solve these problems, a method of increasing the height of the edge of the container has been devised (for example, Patent Document 1). However, a microwave oven generally sold for home use cannot be made unlimitedly high because the height in the cabinet is determined to some extent. In addition, there is a problem that it becomes difficult to eat due to the height of the edge of the container, or it becomes difficult to store in the container shelf. Further, Patent Document 1 describes a method for solving a problem at the time of eating by enabling removal of a raised portion of the container. However, in such a configuration, the container is reused. There was a problem that could not be.

  Moreover, the method of using a lid | cover has been devised (for example, patent document 2). However, when the lid is hermetically sealed, there is a risk that food generated in the container may explode due to the internal pressure in the container being increased by steam generated during cooking in the microwave oven. In addition, even if a hole for venting steam is provided to prevent the internal pressure in the container from increasing, if the lid and the liquid level of the food or drink in the container are close, the liquid and solids of the food or drink from the hole There is a risk of leakage. In order to prevent this, it is necessary to increase the height of the lid itself, but the height of the lid itself is limited by the height in the microwave oven. Patent Document 2 describes a blowout prevention lid in which a hollow portion is formed inside a lid and a through hole communicating with the hollow portion is provided in each of an upper wall and a lower wall forming the hollow portion. . However, in such a configuration, although the spillage can be prevented, the solid matter spilled together with the liquid from the through hole in the lower wall is heated without returning to the inside of the container, and the lid becomes dirty and the texture is uneven. There was a problem of going out.

  In addition, a microwave cooker including a lid, a cap, and a container is known (for example, Patent Document 3). Patent Document 3 is a microwave cooker composed of a container, a lid, and a cap. The container and the lid, the lid and the cap are respectively fitted, the lid has an annular lid concave portion, and the center of the lid concave portion is There is described a microwave cooker which is open and has a steam discharge groove on a side surface, and the steam in the container is discharged from the cover opening and the cover steam discharge groove. However, in such a configuration, the shape of the lid, the cap structure, and the like are complicated, and there is a problem that a cap is required in addition to the lid to prevent spillage.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1-4 is explanatory drawing of the lid | cover 1a which comprises the microwave oven cooker concerning 1st embodiment. 1 is a perspective view, FIG. 2 is a top view, FIG. 3 is a cross-sectional view taken along the line AA ′, and FIG. 4 is a cross-sectional view taken along the line AA ′ showing the state fitted to the container.

  As shown in FIGS. 1 to 3, the lid 1 a has a substantially frustoconical shape including a lid top surface 100, a lid outer peripheral portion 120, and a lid side surface 110 connecting the lid top surface 100 and the lid outer peripheral portion 120. In addition, a projection 140 formed by being pushed downward in the vicinity of the center of the lid top surface 100 and a steam discharge hole 170 provided on the lid top surface 100 are provided. The protrusion 140 has a substantially inverted truncated cone shape composed of a non-opening protrusion tip 150, an opening surface surrounded by the lid-projection boundary 160, and a side surface connecting the protrusion tip 150 and the lid-projection boundary 160. Thus, the lid center 180 is disposed. The steam discharge hole 170 is configured by a substantially elliptical hole. Four steam discharge holes 170 are arranged around the lid-projection boundary 160 on the lid top surface 100. Each of the steam discharge holes 170 is provided at a position including a point equidistant from the lid center 180, and the distance between the adjacent steam discharge holes 170 is the same distance. The steam discharge holes 170 facing each other are provided at positions including point-symmetric positions with respect to the lid center 180.

  The material of the lid 1a is not particularly limited as long as microwave cooking is possible. Examples thereof include plastic materials such as polypropylene, polyethylene terephthalate, crystallized polyethylene terephthalate, and polysulfone in addition to glass and ceramics. In view of ease of molding, a plastic material is preferable, and polypropylene is particularly preferable because of its high heat resistance. The same applies to lids 1b to 1d and containers 2a and 2b described later.

  The method for forming the lid 1a is not particularly limited. For example, when the material of the lid 1a is glass, there may be mentioned press molding, blow molding, mold molding and the like. Moreover, when the material of the lid 1a is a plastic material, thermoforming, injection molding, and the like can be given. The same applies to lids 1b to 1d and containers 2a and 2b described later. The shape of the lid 1a does not have to be substantially frustoconical as illustrated, and can be appropriately set by those skilled in the art according to the container. The same applies to lids 1b to 1d described later.

  The protrusion 140 is formed integrally with the lid 1a and has a shape in which the center on the lid top surface 100 is recessed downward. Moreover, you may provide the projection part 140 by adhere | attaching a member to the lid | cover 1a. Considering the labor of bonding, the protrusion 140 is preferably formed integrally with the lid 1a. In particular, when the material is polypropylene, the lid 1a can be easily formed by thermoforming a polypropylene sheet. Thereby, since a plurality of lids can be overlapped, it is convenient for transportation and storage.

  Further, the shape of the protrusion 140 does not have to be a substantially inverted truncated cone shape as shown in the figure, and a person skilled in the art can block the rise of bubbles during cooking in a microwave oven according to the shape of the container or lid. Can be appropriately designed. However, as shown in the figure for the protrusion 140, the horizontal cross-sectional area of the protrusion is designed to become smaller as it approaches the tip of the protrusion, thereby dispersing the rising force of bubbles over the entire lid. The effect is easy.

  One protrusion 140 is arranged at the center of the lid top surface 100 so as to include the lid center 180. The arrangement of the protrusions 140 is not particularly limited. However, in the case of the one having one protrusion such as the lid 1a, the rise of the bubbles is efficiently suppressed and the force is evenly diffused to the lid. It is preferable to be provided at a position including the center. Further, the number of protrusions 140 is not limited to one, and two or more may be provided. The same applies to the protrusions 141 to 144.

  The protrusion tip 150 is non-opening, but the term “non-opening” as used herein means that the protrusion is not a complete opening, and a small hole may be opened within a range in which the protrusion can suppress the rise of bubbles. However, it is more preferable that the tip of the protrusion is a complete non-opening. The shape of the protrusion tip 150 may be other than the flat shape as shown in the figure, and may be, for example, a shape in which the tip is pointed downward, a shape curved downward, or a shape curved upward. For those having a relatively low viscosity of the food / drink liquid part, a shape with a pointed downward tip or a downward curved shape is preferred in order to make it easier to break the rising bubbles. For those having a high viscosity of the food / drink liquid part, a flat shape or a curved structure in the upward direction is preferable in order to suppress the rise of bubbles.

  As shown in FIG. 4, the protrusion tip 150 is disposed above the food liquid surface when the lid 1 a is fitted into the container. If the protrusion tip portion 150 is disposed below the food liquid level, the rise of the bubbles cannot be suppressed. Further, if the protrusion tip 150 is disposed at a position close to the lid top surface 100, the distance between the vapor discharge hole 170 and the foam becomes short, and the liquid portion of the food and drink leaks from the vapor discharge hole 170. There is a risk of taking out. The position of the protrusion tip 150 is not particularly limited because the preferred conditions vary depending on the shape of the container and the lid and the position of the food liquid level in the container, but it is preferably 10 mm or more from the position where the steam discharge hole 170 is located, particularly preferably. It is preferable to be provided in the downward direction by 20 mm or more.

  The area of the protrusion tip 150 is designed to be about 7% of the area of the lid opening 130. The area of the projection tip 150 is not particularly limited because the preferred conditions vary depending on the shape of the projection tip 150, the shape of the container and the lid 1a, and the position of the food liquid level in the container, but the lid 1a and the container are not limited. It is preferable to set so that it may become 1 to 80% with respect to the surface to contact. If it is less than 1%, it is difficult to suppress the rise of the foam, and if it exceeds 80%, there is no place for the foam to be suppressed, and the liquid portion of the food or drink is more likely to spill from the steam discharge hole 170. In addition, when a plurality of protrusion tip portions 150 are provided, the total area of the protrusion tip portions 150 may be designed to be 1 to 80%. The same applies to the protrusion tip portions 151 to 154.

  The steam discharge holes 170 are substantially oval, and four are disposed on the top surface 100 of the lid. However, the shape and number of the steam discharge holes may be discharged and can be appropriately set by those skilled in the art. . In order to efficiently discharge the steam, it is preferable to arrange two or more steam discharge holes. However, it is necessary to arrange the vapor discharge hole at least above the position of the protrusion tip, and it is preferable to arrange it at a position as high as possible in the lid. Further, four steam discharge holes 170 are arranged around the lid-projection boundary portion 160 on the lid top surface 100, and each is equidistant from the lid center 180, and the distance between the adjacent steam discharge holes 170 is the same. The vapor discharge holes 170 that are equidistant and face each other are arranged at positions symmetrical with respect to the lid center 180. By arranging the steam discharge holes evenly around the lid-projection boundary in this way, not only the steam is evenly discharged from the inside of the container, but also the force that bubbles push up the projection can be evenly released to the entire lid. it can.

  The total area of the steam discharge holes 170 is designed to be about 10% with respect to the area of the lid opening surface 130. The total area of the steam discharge holes is not particularly limited because preferred conditions vary depending on the shape of the container and lid, the shape and number of the steam discharge holes, etc., but it is 1 to 50 with respect to the surface where the lid and the container contact. It is preferable to set to be%. If it is less than 1%, the steam is not discharged smoothly, and the vapor pressure in the container increases. If it exceeds 50%, it will be difficult to prevent the liquid part of food and drink from scattering.

  As shown in FIG. 4, the lid 1a can be fitted so as to be inscribed in the container without a gap. Therefore, in the container according to the first embodiment, at least a part of the horizontal cross-sectional area of the container is smaller than the area of the opening 130 of the lid 1a as in the case of the container 1, or the lid 1a is included in the container 2 as in the case of the container 2. A portion for placing the lid 1a inside the container is provided for contact. In a container having a portion for placing a lid such as the container 2, a flange or the like can be attached to the lid outer peripheral portion 120. Since the bubbles that have risen on the wall surface of the container at the time of microwave oven cooking rise inward on the lid wall surface and intensify the adhesion between the lid and the container, the lid is difficult to come off. The lid 1a does not have a special structure for fitting with a container such as the lid 1b. However, even in such a case, the lid 1a can be fitted if it is fixed to the extent that it does not come off during microwave cooking. It can be said that.

FIGS. 5 to 7 are diagrams showing states during microwave cooking, FIG. 5 is a microwave cooking state when a lid is not used, and FIG. 6 is a microwave oven cooking when a lid having no protrusion is used. FIG. 7 is a diagram showing a microwave cooking state when the lid 1a constituting the microwave oven according to the first embodiment is used.

As shown in FIG. 5, in the case of cooking in a microwave oven without using a lid, at the initial stage of boiling when the liquid portion of the food and drink begins to boil, the bubbles rise along the container wall surface, and the food and drink convect in the container. At the middle stage of boiling, the bubbles begin to rise to the dome shape, and at the later stage of boiling where the convection is further increased, the bubbles rise further, and when a force exceeding the surface tension is applied, the liquid portion of the food and drink spills out of the container. In addition, when large bubbles are crushed, a part of the liquid portion of the food and drink is scattered outside the container.

  In addition, as shown in FIG. 6, in the case of using a lid that does not have a protrusion, in the initial stage of boiling, bubbles rise along the container wall surface and the lid wall surface, and when the middle stage of boiling is reached, the lid is not used. In the same way as in the case, the foam swells in a dome shape, and when the lid is low at the end of boiling, a part of the foam where the liquid part of the food and drink has risen leaks out of the steam discharge hole and blows out of the container. . Therefore, when using a lid that does not have a protrusion, it is necessary to increase the height of the lid itself in order to counter the rising of bubbles. However, since the height of a microwave oven for home use is determined to some extent, the height of the lid itself is limited.

  On the other hand, as shown in FIG. 7, in the case of using the lid 1a, bubbles rise along the container wall surface and the lid wall surface in the initial stage of boiling and in the middle stage of boiling as in the case of the lid having only the steam discharge holes. When the convection begins, the bubble rises to a dome shape. However, in the latter stage of boiling, the rise of the bubble is suppressed by the protrusion tip 150 of the protrusion 140 provided in the lid 1a, and the suppressed bubble eventually breaks. It bubbles and is discharged from the steam discharge hole 170 as steam. At this time, by keeping a space between the foam and the steam discharge hole 170, the discharge of the steam becomes smooth, and when the foam breaks, the liquid portion of the food and drink can be prevented from splashing out of the container. By providing the projection 140 in this way, the height of the lid itself can be reduced.

  As described above, by using the lid 1a that constitutes the microwave oven according to the first embodiment, it is possible to prevent the liquid portion of the food or drink from being blown out or scattered during cooking in the microwave oven.

  Next, with reference to FIGS. 8-14, the lid | cover 1b-1e which is a modification of the lid | cover which comprises the microwave oven cooker concerning 1st embodiment is demonstrated.

  FIGS. 8-11 is the figure explaining the lid | cover 1b which is a modification of the lid | cover which comprises the microwave oven cooker concerning 1st embodiment. 8 is a perspective view, FIG. 9 is a top view, FIG. 10 is a cross-sectional view taken along line B-B ′, and FIG. 11 is a cross-sectional view showing a state in which the lid 1 b is fitted into the container.

As shown in FIGS. 8 to 10, the lid 1 b is substantially the same in shape as the lid 1 a shown in FIGS. 1 to 3, but has a structure in which the lid outer peripheral part 121 can be fitted to the container.
The lid outer peripheral portion 121 of the lid 1b is formed on the outermost outer periphery 121a of the lid, the outer peripheral surface 121c of the lid that rises so as to cover the container from the outermost outer periphery 121a, the outer peripheral flange 121b that is in close contact with the edge of the container, and the outer peripheral surface 121c. In order to fit the container and the lid 1b, a lid outer peripheral recessed portion 121d formed by recessing the lid outer peripheral side surface portion 121c toward the container side is provided. The lid outer peripheral recesses 121d are arranged at substantially equal intervals on the lid outer peripheral side surface 121c.
As shown in FIG. 11, the edge of the container is in close contact with the inside of the lid outer peripheral flange 121b, and is fixed in the space inside the lid outer peripheral flange 121b and the lid outer peripheral recess 121d, whereby the container and the lid are fitted.

  The mechanism for fitting the lid and the container may be a mechanism other than those shown in FIGS. 8 to 11 as long as the structure can be fitted to the container. By fitting with the container, cooking can be performed without removing the lid from the container due to the force received when the protrusion of the lid suppresses the rise of bubbles. Moreover, the possibility of the liquid portion of food and drink popping out is low and high in safety when carried after cooking.

  FIG. 12 is a perspective view showing a lid 1c which is a modified example of the lid constituting the microwave oven according to the first embodiment.

  As shown in FIG. 12, the lid 1 c is a dome-shaped lid, and has a projection 142 whose center of the lid is curved downward and recessed, and a non-opening around the lid-projection boundary 162 on the lid top surface 102. Three steam discharge holes 172 are provided at a position above the protrusion tip portion 152 of the above. The steam discharge hole 172 is formed by making a cut in an arc shape that leaves a part of a circle on the lid top surface 102 and bending the cut portion inside the container. The steam discharge holes 172 are each equidistant from the lid center 182, and the adjacent steam discharge holes 172 are arranged at equal distances. Although not shown, the lid 1c is fitted in a form inscribed in the container without a gap.

  As shown in FIG. 12, the shape of the lid according to the first embodiment may be a dome shape. In the case of such a shape having no lid side surface, it is preferable that the vapor discharge hole is arranged at a position above the tip of the protrusion and as high as possible so that bubbles do not reach. In addition, the steam discharge hole 172 is not a complete hole but is formed by bending a part of the lid inward, and in this case, the portion of the liquid part of the food or drink from the steam discharge hole is bent by the inside of the container. Spattering can be prevented.

  FIG. 13: is a perspective view which shows the lid | cover 1d which is a modification of the lid | cover which comprises the microwave oven cooker concerning 1st embodiment.

  As shown in FIG. 13, the lid 1 d has a shape of a regular truncated pyramid, and a projection 143 that is recessed downward in a regular prism shape at the center of the lid top surface 103 of the lid and a square 4 on the lid top surface 103. Two steam exhaust holes 173 are provided. The steam discharge holes 173 are arranged on the diagonal line of the square opening surface surrounding the lid-projection part boundary portion 163 so as to be equidistant from the lid center line 183. Although not shown, the lid 1d is fitted in a form inscribed in the container without a gap.

  If the opening surface of the container is a square, the container and the lid can be brought into close contact with each other by making the lid opening surface 133 square like the lid 1d shown in FIG. The shape of the lid is not limited to a square, and the shape of the lid can be appropriately set so as to be in close contact with the container according to the shape of the container. For example, if the container opening surface is octagonal, the lid may be designed so that the lid opening surface is octagonal. Further, as shown in FIG. 13, the shape of the protrusion 143 is designed to be a regular prism shape so that rising bubbles can be uniformly suppressed in accordance with the shape of the lid opening surface 133. Further, as shown in FIG. 13, the steam discharge holes 173 are respectively equal to the lid center 183 on the diagonal line of the square opening surface surrounding the lid-projection boundary portion 163 so that the steam can be discharged uniformly from the lid. It is arranged to be a distance. As described above, the shape of the protrusion and the arrangement position of the steam discharge hole can be appropriately set according to the shape of the lid.

  FIG. 14: is a perspective view which shows the lid | cover 1e which is a modification of the lid | cover which comprises the microwave oven cooker concerning 1st embodiment.

  As shown in FIG. 14, the lid 1 e has a disk shape and includes three cylindrical protrusions 144 and seven circular steam discharge holes 174. The protrusion 144 has a non-opening at the protrusion tip 154, is equidistant from the lid center 184, and the distance between adjacent vapor discharge holes 174 is at an equal distance on the back side of the lid top surface 104. It is arranged in a form that adheres to the lid on the surface. One of the steam discharge holes 174 is disposed so as to include the lid center 184, the remaining six are disposed at an equal distance from the lid center 184, and the adjacent steam discharge holes 174 are disposed at an equal distance. The three steam discharge holes 174 surrounding one of the protrusions 144 are arranged at an equal distance from the center of the protrusion 144. Although not shown in the drawing, the lid 1e is fitted to the container so as to be inscribed without a gap.

  As shown in FIG. 14, the shape of the lid according to the first embodiment may be a flat plate shape. In this case, when the lid is fitted to the container, the protrusion tip 154 needs to be adjusted to a position above the food / drink liquid level in the container. Moreover, you may comprise in the form which adhere | attaches a projection part directly on a lid | cover like the projection part 144 of the lid | cover 1e.

  When there are a plurality of protrusions like the lid 1e, it is not always necessary to dispose the protrusions at the center of the cover, and it is preferable to dispose the protrusions at a position where the rise of bubbles can be suppressed evenly. For example, the lid 1e includes three projections 154, and each projection 154 is equidistant from the lid center 184, and adjacent projections 154 are arranged at equidistant positions. . As described above, the bubbles can be uniformly prevented from rising by being arranged at an equal position with respect to the center of the lid. In addition, when there are two protrusions, it is preferable that the protrusions are arranged so as to be symmetrical with respect to the lid center. In addition, when there are four or more protrusions, each protrusion is equidistant from the center of the lid, and not only the adjacent protrusions are arranged at the same distance, but also the protrusion at the center of the lid. It is also possible to arrange one part so that the protrusions adjacent to the remaining protrusions are equidistant, and the distance from the center of the lid is also equidistant.

  As for the lid 1e, a plurality of protrusions are arranged and a vapor discharge hole may be provided in the center of the lid, and the vapor discharge hole is uniform with respect to the entire lid and the protrusion. It is preferable to arrange them so that they are equidistant from the center of the protrusions in the periphery, and the distances between adjacent steam discharge holes are also equidistant. By doing so, the force received by the protrusion due to the rising of the bubbles can be evenly released to the entire lid, and the steam can be discharged smoothly.

  Then, the microwave oven cooker 3a concerning 1st embodiment is demonstrated using FIGS.

  FIGS. 15-18 is a figure which shows the microwave oven 3a concerning 1st embodiment. 15 is a perspective view of the microwave cooker 3a, FIG. 16 is a top view of the container 2a, FIG. 17 is a cross-sectional view taken along the line CC ′ of the container 2a, and FIG. 18 is C in a state where the lid 1a is fitted to the container 2a. FIG. Since the lid 1a has been described with reference to FIGS. 1 to 3, the container 2a and the arrangement of the lid 1a and the container 2a will be described.

  As shown in FIGS. 15 to 17, the container 2 a is an inverted frustoconical container including a container opening 200, a container bottom surface 210, and a container side surface 220 that connects the container opening 200 and the container bottom surface 210. Moreover, the lid | cover installation part 240 for putting the lid | cover 1a on a container without a clearance gap is comprised inside the container. The lid installation part 240 is formed by bending a part of the container horizontally in the container outer direction. Therefore, as shown in FIG. 18, the lid 1 a can be fitted in a form inscribed in the container 2 a without a gap by being placed on the lid installation portion 240. In this state, the lid 1a is not firmly fixed to the container 2a. However, the lid 1a and the container 2a are also fitted in this case because the lid 1a is not displaced when cooking in a microwave oven as will be described later. It can be said.

About the shape of the container of a microwave oven, shapes other than the substantially inverted truncated cone shape as shown in FIGS. When the lid and the container are inscribed as in the case of the lid 1a and the container 2a, at least part of the horizontal cross-sectional area of the container is smaller than the area of the opening of the container or the inside of the container to inscribe the lid It is necessary to provide a part for placing a lid, such as the lid installation part 240. If it is a structure like the lid | cover installation part 240, the joining of a container and a lid | cover can be strengthened by attaching a flange to the lid | cover outer peripheral part 120 of the lid | cover 1a.
In addition, as long as the lid can be inscribed in the container without a gap, the portion for placing the lid is not limited to the structure of the lid installation portion 240.

  As shown in FIGS. 19-22, the container and lid concerning 1st embodiment may be installed in the form which fits. When the lid and the container are fitted, the shape of the entire container is not particularly limited, but is not limited to the structure of the lid and the container as shown in FIGS. 8 to 10 and FIGS. What is necessary is just to fit a lid | cover and a container.

  FIG. 23: is sectional drawing which shows the state at the time of the microwave oven cooking of the microwave oven cooker integrated type food 4 concerning 2nd embodiment.

  As shown in FIGS. 23 (a) and 23 (b), a microwave cooker-integrated food 4 includes a solid food 410 and a liquid food 420 in a microwave cooker 3a 'composed of a lid 1a' and a container 2a. The food and drink 400 consisting of the above is included. Here, the lid 1a 'is obtained by further extending the lid protrusion 140 of the lid 1a downward, and the other configuration is the same as the lid 1a. In either case of FIGS. 23A and 23B, the tip of the lid protrusion 140 ′ is located above the uppermost part of the food and drink 400.

  The food and drink 400 is made up of food and drink such as frozen food and chilled food, and is made up of foods and drinks that contain a lot of viscous liquid at the time of eating, such as soup, risotto, ramen, soup pasta, and curry. The solid food and drink 410 is a portion showing solidity in the food and drink 400, and specifically includes ingredients, noodles, rice, and the like. Moreover, the liquid food / beverage 420 is a viscous liquid part of the food / beverage 400, and specifically includes various foods / soups.

  When the food / drink 400 is a frozen food, it is a solid food / drink 410 because it is frozen at the start of cooking, but also includes those that change to a liquid food / drink 420 when dissolved by heating during cooking. It is. Moreover, when the food / beverage 400 is a chilled food, it is solidified in the form of a jelly at the start of cooking to be a solid food / beverage 410, but includes food that changes to a liquid food / beverage 420 by heating during cooking.

  23 (a) and 23 (b) is a state in which the food / beverage 400 is directly contained in the microwave oven 3a 'during microwave oven cooking. The food and drink 400 does not necessarily have to be included in the microwave cooker 3a 'when selling the microwave cooker-integrated food 4 or the like, and may be sold as a single unit. In addition, the food and drink 400 may be further individually packaged when sold in the microwave cooker 3a '. However, when the microwave oven is cooked, the food and drink 400 is discharged from the individual package. It is directly contained in the cooker 3a 'and is set with the lid 1a' and the container 2a fitted.

  Hereinafter, how the microwave oven cooker integrated food 4 is cooked in a microwave oven will be briefly described. FIG. 23A is an example in which the liquid portion is relatively large and the uppermost portion of the liquid food 420 reaches the upper side than the uppermost portion of the solid food 410. In such a case, as in the case described with reference to FIG. 7, even when the food liquid level rises as foam or the like by microwave cooking, the rise of the foam is suppressed by the lid protrusion 140 ′, Spattering can be prevented.

  On the other hand, FIG. 23 (b) is an example in which the solid portion is relatively large and the uppermost portion of the solid food / drink 410 reaches an upper side than the uppermost portion of the liquid food / beverage 420. In such a case, since there are fewer liquid foods and drinks 420, spillage and scattering due to the rising of the bubbles are unlikely to occur in the first place, but even when the bubbles are rising, the lid protrusion 140 ′ as in FIG. Since the rise of bubbles is suppressed by this, it is possible to prevent spills and splashes.

  In addition, when the food and drink 400 is a frozen food or a chilled food, the solid food or drink 410 is large as shown in FIG. 23B because it is frozen or solidified in a jelly shape at the start of microwave cooking. In some cases, the food and drink 400 may be all solid food and drink 410. In this case, a part of the solid food 410 is dissolved during cooking, and the liquid food 420 is changed. Even in such a case, when the uppermost part of the food and drink 400 is arranged below the front end of the lid protrusion 140 ′ during cooking, the state shown in FIG. Can be prevented, and spills and splashes can be prevented.

  Furthermore, when the food and drink 400 is a frozen food or a chilled food, as shown in FIG. 24, the top of the solid food 410 comes above the tip of the lid protrusion 140 ′ at the start of cooking. There is a case. Even in such a case, the lid protrusion portion is configured such that the uppermost portion of the food and drink 400 comes below the tip of the lid protrusion portion 140 ′ as shown in FIG. The rise of bubbles is suppressed by 140 ', and spilling and scattering can be prevented.

  Note that the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the invention when it is practiced. Furthermore, the above embodiments include inventions at various stages, and various inventions can be extracted by appropriately combining a plurality of disclosed constituent elements. For example, even if some constituent requirements are deleted from all the constituent requirements shown in the embodiment or some constituent requirements are combined in different forms, the problems described in the column of the problem to be solved by the invention are not solved. When the effects described in the column “Effects of the Invention” can be obtained, a configuration in which these constituent requirements are deleted or combined can be extracted as an invention.

  For example, in the second embodiment, it has been described that the food and drink 400 is sold as one unit with the microwave cooker 3a ′. However, the present invention is not limited to such a mode. For example, the food and drink 400 is illustrated in the first embodiment. Moreover, like the microwave oven cookers 3a-3b, it may be distributed as a product separate from food and drink, and may be cooked with food and drink corresponding to these microwave oven cookers. On the contrary, it is good also as a microwave oven cooking appliance integrated food which united the microwave oven cookers 3a-3b and food and drink 400 concerning 1st embodiment.

In addition, the food and drink 400 may be one in which a predetermined amount of water is poured immediately before cooking in the microwave oven. In this case, it is only necessary that the uppermost portion of the food and drink 400 is adjusted to be below the lid protrusion 140 ′ when the lid is fitted after the addition of water.
