Description

[Technical field]

[0001] The present invention relates to a cooking vessel capable of pressure cooking in a microwave oven and a microwave oven having a control program for said cooking vessel. [Background technology]

[0002] As an example of a pressure cooking container for a microwave oven, Patent Document 1 discloses a pressure cooker having in its lid 2 first and second valve means 16, 18 for discharging excessive pressure to the outside, and a pressure display means 20 that allows the state of the internal pressure to be visually confirmed from the outside when the pressure increases. When the pressure cooker is heated in a microwave oven, the pressure inside the pot rises. When the pressure inside the pot is low, the valve ball 19 of the second valve means 18 closes the steam hole and steam cannot escape. When the pressure inside the pot subsequently rises to a high pressure, the steam pushes up the valve ball 19 of the second valve means 18, and steam escapes through the gap between the second valve means 18 and the valve ball 19, causing the pressure inside the pot to drop.

[0003] [Patent Document 1] JP 2015-077326 A Summary of the Invention [Problem to be solved by the invention]

[0004] In the above pressure cooker, even during normal cooking, the pressure inside the pot rises due to the valve ball 19. On the other hand, during pressure cooking, the valve ball 19 is pushed up, causing the pressure inside the pot to drop, making it impossible to maintain a high pressure state. An object of the present invention is to provide a cooking container in which the pressure inside the container is unlikely to increase during normal cooking and in which a high-pressure state can be easily maintained during pressure cooking. [Means for solving the problem]

[0005] The cooking container of the present invention is a cooking container having a container body and a lid body, in which a communication port connecting the inside of the container to the outside of the container is provided on one of the container body and the lid body, and a blocking portion that blocks the communication port is provided on the other of the container body and the lid body. Effect of the Invention

[0006] According to the above configuration, normal cooking is possible when the communication port is not blocked by the blocking portion, and pressure cooking is possible when the communication port is blocked by the blocking portion, since the high pressure state is maintained.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0008] <Summary> A first cooking vessel according to one aspect of the embodiment is a cooking vessel having a vessel body and a lid body, in which a communication port connecting the inside of the vessel to the outside of the vessel is provided on one of the vessel body and the lid body, and a blocking portion for blocking the communication port is provided on the other of the vessel body and the lid body. In a second cooking vessel according to one aspect of the embodiment, in the first cooking vessel, the communication opening is provided in the lid body, the closing part is provided in the vessel body, and the closing part closes the communication opening when the lid body is attached to the vessel body in a closed position, thereby making it easy to open and close the communication opening by attaching the lid body to the vessel body. A third cooking vessel according to one aspect of the embodiment is the second cooking vessel, wherein the vessel body has a bottom wall portion and a peripheral wall portion extending upward from a periphery of the bottom wall portion, and the closing portion protrudes from an upper end portion of the peripheral wall portion toward a center of the peripheral wall portion, thereby making it easy to provide the closing portion. A fourth cooking vessel according to one aspect of the embodiment is the cooking vessel according to the second or third aspect, wherein an upper surface of the closing portion has an upwardly bulging shape, thereby enabling the communication opening to be closed with high sealing performance. A fifth cooking vessel according to one aspect of the embodiment is any one of the cooking vessels according to the second to fourth aspects, wherein the communication opening is formed by a through hole in the vertical direction of an opening / closing member attached to the top wall of the lid body, and the bottom surface of the opening / closing member is shaped to bulge downwards, thereby making it possible to easily provide the communication opening and to close the communication opening with high sealing performance.

[0009] A first microwave oven according to one aspect of the embodiment has cooking modes for automatic cooking using any one of cooking containers 1 to 5, the cooking modes including a pressure cooking mode, which performs, in this order, a first step of operating at a first output or higher, a second step of intermittently operating at a second output equal to or lower than the first output, and a third output lower than the second output, thereby enabling safe pressure cooking. In a second microwave oven according to one aspect of the embodiment, the pressure cooking mode of the first microwave oven includes a third step of operating the microwave oven at a fourth output lower than the third output after the second step, whereby the pressure inside the container is reduced in pressure when the pressure cooking is completed, thereby improving safety. A third microwave oven according to one aspect of the embodiment is the first or second microwave oven, further comprising a locking mechanism for locking and unlocking the opening and closing of a door body, and a control unit for controlling the locking mechanism, and the control unit releases the lock when the pressure cooking mode ends. This prevents the cooking container from being removed during pressure cooking, thereby improving safety.

[0010] First Embodiment 1. Overall structure Cooking container (hereinafter simply referred to as "container") X is a container for a microwave oven. As shown in FIG. 1, container X includes a container body 1 and a lid body 5. Container X can be used for pressurized cooking, in which high pressure is maintained inside the container, and for normal cooking, in which high pressure is not maintained inside the container. Here, as shown in FIG. 2, a container X will be described in which a communication port 61 that connects the inside of the container with the outside of the container is provided in the lid body 5, and a blocking portion 19 that blocks the communication port 61 is provided in the container body 1. The lid body 5 is disposed in a first position relative to the container body 1 during pressurized cooking, and in a second position during normal cooking. The second position is not exactly a single point, but includes a certain range. The first position corresponds to an example of the "closed position" in the present invention. The closing portion 19 closes the communication opening 61 when the lid body 5 is disposed in a first position relative to the container body 1, and opens the communication opening 61 when the lid body 5 is disposed in a second position relative to the container body 1. This makes it possible to perform pressure cooking by disposing the lid body 5 in the first position relative to the container body 1, and makes it possible to perform normal cooking by disposing the lid body 5 in the second position relative to the container body 1, allowing the user to select between pressure cooking and normal cooking by selecting the position of the lid body 5, improving usability.

[0011] 2. Container body The following description will be mainly made with reference to FIG. 2 and FIG. The container body 1 has at least a bottom wall 11, a peripheral wall 13, a container-side mounting mechanism 15, a container-side locking mechanism 17, and a closing part 19. The container body 1 may have, for example, a handle 21 or a handle or other handle in addition to the bottom wall 11, and here has a handle 21. The container body 1 is made of a heat-resistant resin material, and integrally has the bottom wall 11, the peripheral wall 13, the container-side mounting mechanism 15, the container-side locking mechanism 17, the closing part 19, and the handle 21. In other words, the container body 1 is an integrally molded product.

[0012] (1) Bottom wall The bottom wall portion 11 has a circular shape when viewed from above, but is not limited to this shape and may be rectangular, elliptical, or the like.

[0013] (2) Peripheral wall part The peripheral wall portion 13 extends upward from the peripheral edge of the bottom wall portion 11. Here, the peripheral wall portion 13 has a cylindrical shape, but is not limited to this shape and may be a rectangular cylindrical shape, an elongated cylindrical shape, etc. Here, the cylindrical axis of the peripheral wall portion 13 is also the central axis of the container body 1 and the container X, and hereinafter will be simply referred to as the central axis. The upper end of the peripheral wall portion 13 forms an opening 23 for inserting or removing food to be cooked. A handle 21 is provided on the upper portion of the outer periphery of the peripheral wall portion 13.

[0014] (3) Container side attachment mechanism The container side mounting mechanism 15 and the lid side mounting mechanism 55 constitute a mounting mechanism, and detachably mount the lid main body 5 to the container main body 1. When the lid body 5 is rotated around the central axis relative to the container body 1, the lid side mounting mechanism 55 engages with the container side mounting mechanism 15. The container side mounting mechanism 15 is composed of an outward protrusion 25 that protrudes radially outward from the upper end of the peripheral wall 13. As shown in Fig. 2, there are multiple outward protrusions 25 (e.g., six) at equal intervals in the circumferential direction.

[0015] (4) Container locking mechanism The container-side locking mechanism 17 and the lid-side locking mechanism 57 constitute a locking mechanism that locks (makes it difficult to remove) or unlocks the attached state of the lid main body 5. Here, the attached state is locked by restricting (making it difficult to rotate) the rotation of the lid main body 5 around the central axis. When the lid body 5 is attached to the container body 1 and rotated about the central axis in the attached state, the lid side locking mechanism 57 fits into the container side locking mechanism 17. The container side locking mechanism 17 is composed of a recess 27 provided on the underside of the outward extension 25. A protrusion 73 of the lid side locking mechanism 57 fits into the recess 27. The locking mechanism is provided in two outward extensions 25 and inward extensions 71 facing each other across the central axis out of the multiple outward extensions 25 and inward extensions 71 of the attachment mechanism.

[0016] (5) Occlusion area The blocking portion 19 is provided at the upper end of the peripheral wall portion 13. The blocking portion 19 protrudes from the peripheral wall portion 13 toward the center (central axis). When viewed from above, the blocking portion 19 here protrudes in a triangular or trapezoidal shape. The blocking portion 19 is provided in two locations facing each other across the central axis. The blocking portion 19 is located on the opposite side of the peripheral wall portion 13 from the circumferential center of the handle 21. The upper surface of the blocking portion 19 is shaped to bulge upward. The upper surface of the blocking portion 19 may bulge linearly, may bulge in a convex curved shape, or may bulge in a shape that combines straight lines and curved lines. When the lid body 5 is attached to the container body 1 in a locked state, the center position of the bulged portion of the blocking portion 19 and the center position of the communication port 61 are configured to coincide. This improves the sealing performance of the blocking portion 19. The highest position (most bulged position) on the upper surface of the blocking portion 19 is flat and larger than the communication port 61. This increases the area that can block the communication port 61 relative to the communication port 61, and the inside of the container can be easily sealed by simply attaching the lid body 5 to the container body 1 in a locked state.

[0017] (6) Handle The handles 21 are provided at opposing positions across the central axis, and there are two in total. The handles 21 protrude outward in the radial direction. The handles 21 have a container side mark 29 that indicates that the lid body 5 is attached to the container body 1 in a first position, and serves as a mark for attaching the lid body 5 in the first position.

[0018] 3. Lid body The following description will be mainly made with reference to FIG. 2 and FIG. The lid body 5 is detachably attached to the container body 1 so as to cover the opening 23 of the container body 1. The lid body 5 has at least a top wall portion 51, a peripheral wall portion 53, a lid-side mounting mechanism 55, a lid-side locking mechanism 57, and a pressure adjustment unit 59, and one or more (here, one) communication ports 61 are provided in the top wall portion 51. In addition to the top wall portion 51, the lid body 5 may also have, for example, a handle 21 or a handle or other handle, a pressure display unit 65, and the like, and here, the lid body 5 has a handle 63 and a pressure display unit 65. The lid body 5 is made of a heat-resistant resin material and integrally includes a top wall portion 51, a peripheral wall portion 53, a lid-side mounting mechanism 55, a lid-side locking mechanism 57, and a handle 63. In other words, the lid body 5 is an integrally molded product.

[0019] (1) Ceiling wall The top wall portion 51 has a shape corresponding to the opening 23 of the container body 1, and here has a circular shape. The top wall portion 51 is provided with a pressure adjustment unit 59, a pressure display portion 65, and an opening / closing member 67 for forming the communication port 61.

[0020] (2) Peripheral wall part The peripheral wall portion 53 extends downward from the peripheral edge of the top wall portion 51. Between the upper end portion of the peripheral wall portion 53 and the peripheral edge of the top wall portion 51, an annular packing 69 is provided. A handle 63 is provided on the outer circumferential surface of the peripheral wall portion 53. A lid-side mounting mechanism 55 and a lid-side locking mechanism 57 are provided on the inner circumferential surface of the peripheral wall portion 53.

[0021] (3) Lid side attachment mechanism The lid-side mounting mechanism 55 is configured to be able to engage with the container-side mounting mechanism 15. The lid-side mounting mechanism 55 is configured with an inward protruding portion 71 that protrudes radially inward from the lower end of the peripheral wall portion 53. As shown in Fig. 2, there are a plurality of inward protruding portions 71 (e.g., six in number) at equal intervals in the circumferential direction. The circumferential length of the inward protruding portion 71 is smaller than the interval between two outward protruding portions 25 adjacent to each other in the circumferential direction. At least one (here, two) of the multiple inward protruding portions 71 is provided with a rotation stopper 71a that stops the rotation of the lid body 5 relative to the container body 1 when the lid body 5 is attached to the container body 1. The rotation stopper 71a is provided at the end opposite to the direction of rotation when attaching.

[0022] (4) Lid locking mechanism The lid-side locking mechanism 57 is configured to be able to fit with the container-side locking mechanism 17. The lid-side locking mechanism 57 is configured with a convex portion 73 provided on the upper surface of the inward protruding portion 71. The convex portion 73 fits into the concave portion 27. The convex-concave relationship between the concave portion 27 and the convex portion 73 may be reversed between the container body 1 and the lid body 5.

[0023] (5) Pressure adjustment unit The pressure adjusting unit 59 is for keeping the pressure inside the container constant during pressure cooking. The pressure adjusting unit 59 here is of a weight type, and includes a pipe 81 that communicates with the inside of the container, a lever body 83 with a weight that closes the upper end opening of the pipe 81, and a cap 85 provided on the underside of the top wall portion 51, as shown in FIG. Lever body 83 is supported rotatably around the central axis of pipe 81. When lever body 83 is set to a third position with respect to top wall portion 51, it becomes movable in the vertical direction and closes the upper end of pipe 81. In this state, when the pressure inside the container reaches a certain level or higher, it pushes up the weight (lever body 83) to discharge steam. When the lever body 83 is rotated from the third position to the fourth position, the weight (lever body 83) moves above the pipe 81 and separates from the upper end of the pipe 81. This causes the inside of the container to be in a normally open state.

[0024] (6) Pressure display unit The pressure display unit 65 has a pin 87, the lower end of which is located inside the container, movable up and down on the top wall 51. When the pressure inside the container becomes high, the pin 87 rises, and when the pressure inside the container becomes normal, the pin 87 falls. This makes it possible to display the pressure state inside the container. The pin 87 is made of an elastically deformable resin material, for example, a silicon resin material. As shown in Fig. 4, the pin 87 has a covered cylindrical shape and includes a cylindrical portion 871, an upper large diameter portion 873 that closes the upper end of the cylindrical portion 871 and has a larger diameter than the cylindrical portion 871, and a lower large diameter portion 875 that is provided at the lower end of the cylindrical portion 871 and has a larger diameter than the cylindrical portion 871. The cylindrical portion 871 of the pin 87 is inserted into the through hole 51a (see Fig. 3) of the top wall portion 51. The vertical dimension of the cylindrical portion 871 is larger than the thickness of the top wall portion 51, and the pin 87 is supported so as to be movable up and down. When the pressure inside the container exceeds a certain level, the lower large diameter portion 875 of the pin 87 elastically deforms and passes through the through hole 51a. That is, when the pressure exceeds a certain level, the pressure display unit 65 comes out upward from the top wall portion 51, and the internal pressure is released. In other words, the pressure display unit 65 functions as a safety valve. The thickness, diameter, etc. of the lower large diameter portion 875 of the pin 87 are set according to the timing at which the pin 87 comes out (the pressure inside the container).

[0025] (7) Handle The handles 63 are provided at opposing positions across the cylindrical axis of the peripheral wall portion 53, and there are two in total. The handles 63 protrude outward in the radial direction. The handles 63 have a lid side mark 75 that indicates that the lid body 5 is in a first position relative to the container body 1, and serves as a mark for attaching the lid body 5 in the first position. The pressure display unit 65 and the communication port 61 are located on an imaginary line connecting one of the handles 63. 1, when the lid body 5 is attached (locked) to the container body 1 in the first position and viewed from above, the handle 63 coincides with the handle 21 of the container body 1. In other words, the position where the handles 21 and 63 overlap is the "first position" and the locked state.

[0026] (8) Communication port The communication opening 61 is formed by a through hole 671 in the up-down direction of an opening / closing member 67 attached to the top wall portion 51 of the lid main body 5. As shown in Fig. 5, the opening / closing member 67 is cylindrical, and a groove portion 673 extending in the circumferential direction is formed on the outer circumferential surface at the middle portion in the axial direction of the cylinder. The groove portion 673 fits into the through hole 51b of the top wall portion 51 (see Fig. 3). The outer peripheral surface (lower surface) of the bottom portion 675 of the opening / closing member 67 has a shape that bulges downward. The lower surface of the opening / closing member 67 may bulge linearly, may bulge in a convex curved shape on the lower side, or may bulge in a shape that combines straight lines and curved lines. Specifically, it bulges in a dome shape. The through hole 671 (communication port 61) is formed in the part that bulges most downward. This can improve the airtightness with the blocking portion 19. The most bulging position of the lower surface of the opening / closing member 67 is the center of the opening / closing member 67 and the center of the through hole 671. This allows the bottom of the opening / closing member 67 to be evenly deformed when blocked by the blocking portion 19, improving the airtightness.

[0027] 4.Use (1) Attaching the lid body The lid body 5 is placed on the container body 1 so that the inwardly extending portion 71 of the lid body 5 fits between the outwardly extending portions 25 of the container body 1. This causes the upper end of the peripheral wall portion 13 of the container body 1 to come into contact with the packing 69. With the lid body 5 placed, the lid body 5 is rotated relatively to the container body 1 about the central axis, whereby the lid side attachment mechanism 55 engages with the container side attachment mechanism 15. As a result, the lid body 5 is attached to the container body 1.

[0028] (2) Pressure cooking When pressure cooking, the lid body 5 is further rotated relative to the container body 1 from the engaged state in "(1) Attaching the lid body" above so that the lid side mark 75 and the container side mark 29 are aligned. This activates the locking mechanism, and the lid body 5 is attached to the container body 1 in a locked state, and the communication port 61 is blocked by the blocking portion 19. This seals the inside, making pressure cooking possible. Furthermore, with the communication port 61 blocked, the internal pressure is regulated by the pressure adjustment unit 59, making it easier to maintain a high internal pressure state. The closing portion 19 can be easily provided since it is structured to protrude from the peripheral wall portion 13. In addition, since the upper surface of the closing portion 19 bulges upward, the lid main body 5 can be rotated smoothly. Meanwhile, since the lower surface of the opening / closing member 67 also bulges downward, the lid main body 5 can be rotated smoothly. Since the closing part 19 and the opening / closing member 67 bulge toward each other when rotating, the airtightness can be improved even if the opening / closing member 67 and the closing part 19 are out of the normal position (designed position). In other words, the range (rotation range) in which high airtightness can be maintained can be expanded.

[0029] (3) Normal cooking When pressure cooking, in the engaged state of "(1) Attaching the lid body" above, the communication port 61 is not blocked by the blocking part 19. This allows the inside and outside of the container to communicate with each other through the communication port 61, enabling normal cooking. In this way, pressure cooking and normal cooking can be easily selected depending on the attachment position of the lid body 5 to the container body 1.

[0030] <Second embodiment> A microwave oven having a cooking mode for automatic cooking using the container X described in the first embodiment will be described. Note that the pressure cooking mode for pressure cooking is included in the cooking modes. 1. Microwave As shown in Figures 6 and 7, microwave oven Y comprises a housing 103 with an opening, a door 105 attached to housing 103 and enabling the opening to be opened and closed, an operation unit 107 allowing the user to select what to cook, a display unit 109 that supports the user in selecting what to cook and displays the operating status of the cooking content, a heating unit 111 that heats the ingredients to be cooked, an interior light 113 that turns on in conjunction with heating, a fan unit 115 that ventilates in conjunction with heating, and a control unit 117 that controls heating unit 111, display unit 109, interior light 113 and fan unit 115 in accordance with the user's selection. Furthermore, microwave oven Y includes a lock unit 119 that locks door 105 against opening and closing when the pressure cooking mode program is started, and lock unit 119 is controlled to be locked and unlocked by control unit 117. As lock unit 119, for example, an electromagnetic valve such as a solenoid can be used.

[0031] The operation unit 107 has a number of operation buttons. By operating these operation buttons, the user can set the heating output and time, and select a desired menu from among a number of automatic cooking menus. The automatic cooking menus include a pressure cooking mode using a container X, etc. The control unit 117 is composed of a microcomputer and its peripheral circuits, and includes a memory 121 and a timer 123. The memory 121 stores a plurality of control programs corresponding to the automatic cooking menus. The plurality of programs includes a program for executing the pressure cooking mode.

[0032] When the pressure cooking mode is selected, the control unit 117 performs a first step of operating at a first output, and a second step of intermittently operating at a second output equal to or lower than the first output and a third output lower than the second output, in that order. Here, the control unit 117 further performs a third step of operating at a fourth output lower than the third output, after the second step.

[0033] 2. Control Unit The process of the control unit 117 when the pressure cooking mode is selected will be described with reference to FIGS. The control unit 117 starts processing when the user operates the operation unit 107 and selects the pressure cooking mode. When processing starts, after performing zero clearing and the like, timer 123 is started (S1), interior light 113, fan section 115 and lock section 119 are driven (S2), and heating section 111 is driven at the first output (high output operation: P1) until the first time (T1) has elapsed, as shown in FIG. 8 (S3, S4). The first output (P1) here is stored in advance in the memory 121 for each cooking course. The first time (T1) is the time it takes for the pressure in the container X to reach the pressure required for pressure cooking, and is stored in advance in the memory 121 for each cooking course.

[0034] When the first time (T1) has elapsed ("Yes" in S4), the heating unit 111 is driven in intermittent operation with the first output (P1) and the third output (P3) until the second time (T2) has elapsed (S5, S6). In this intermittent operation, as shown in FIG. 8, the first output (P1) is operated intermittently, and when not operating at the first output (P1), the heating unit 111 is operated at the third output (P3) which is lower than the first output (P1). This makes it possible to maintain a pressurized state inside the container X. Note that the duty ratio between the first output (P1) and the third output (P3) for the intermittent operation and the like are stored in advance in the memory 121. Here, the first output (P1) corresponds to an example of the second output (P2) lower than the first output (P1). The third output (P3) may be lower than the first output (P1), which is also the second output (P2), and may include an output of "0". The third output (P3) and the second time (T2) are stored in advance in the memory 121 in correspondence with each cooking course. The third output (P3) is appropriately set depending on the duty ratio of the intermittent operation and the cooking contents.

[0035] When the second time (T2) has elapsed ("Yes" in S6), the heating unit 111 is driven at the fourth output (low output operation: P4) until the third time (T3) has elapsed (S7, S8). This makes it possible to reduce the pressure inside the container X, thereby improving safety. It should be noted that the fourth output (P4) includes a state in which the output is "0" and also includes a low output that corresponds to the "0" state. When the third time (T3) has elapsed ("Yes" in S8), the driving of the heating unit 111 is stopped and the timer 123 is stopped (S9, S10), the driving of the interior light 113, the fan unit 115 and the lock unit 119 is stopped (S11), and the process ends. This can prevent the user from opening the door 105 during cooking, thereby improving safety. When the normal cooking mode is selected in the microwave oven Y using the container X, an intermittent operation may be performed from the first time (T1) to the second time (T2) as shown in Figs. 8 and 9.

[0036] (3)Other In the second embodiment, intermittent operation is performed with the first output (P1) and the third output (P3). However, intermittent operation may be performed with a second output (P2) that is lower than the first output (P1) and higher than the third output (P3) instead of the first output (P1). In the second embodiment, intermittent operation is performed from the first time (T1) to the second time (T2), but continuous operation may also be performed at a fifth output (P5) that has the same energy as the energy (output x time) of the intermittent operation. In steps S3, S5, and S7 in Fig. 8, the output is constant, but it may be varied, for example. Specifically, in step S3, the output may be gradually increased over time. In steps S5 and S7, the output may be gradually decreased over time. The timing for locking the door 105 may be when the program starts, when the pressure inside the container reaches a certain level (before the pressure display unit 65 starts operating), or after a predetermined time has elapsed since the program started. The timing for unlocking the door body 105 may be when the program ends, when the pressure inside the container reaches a certain level (after the pressure display unit 65, which had been operating, has stopped operating), or after a predetermined time has elapsed since the start of step S7.

[0037] Although the embodiment has been described above, the present invention is not limited to this embodiment, and may be modified as follows, for example. In addition, the embodiment and the modified examples may be combined, or the modified examples may be combined. Furthermore, examples not described in the embodiments and modifications, and design changes within the scope of the present invention are also included in the present invention.

[0038] <Modification> 1. Container (1) Although the container X is made of a heat-resistant resin material, it may be made of a material that is at least usable in a microwave oven, such as a heat-resistant resin material or a heat-resistant glass material. (2) Although the container X has the communication port 61 in the lid body 5 and the closing portion 19 in the container body 1, the communication port may be provided in the container body and the closing portion may be provided in the lid body. (3) Although there is one communication port 61 in the embodiment, there may be two or more communication ports. (4) Although the blocking portion 19 is provided on the inside of the handle 21, it may protrude inward (toward the central axis) over a wide range except for a part of the upper end of the peripheral wall portion 13. When protruding over a wide range, the non-protruding portion is configured so that a communication port is located during normal cooking. (5) Although the communication port 61 and the blocking portion 19 are provided on the central axis side of the handles 21, 63, they may be provided in other positions, for example, between the pair of handles.

[0039] <Other> (1) Although the container X is made of a heat-resistant resin material, it may be made of a metal material and may be used for cooking with a cooking device that uses gas, electricity, magnetism, etc., i.e., a cooking device other than a microwave oven. Even in this case, by providing a communication port, it is possible to provide a cooking container in which the pressure inside the container is unlikely to increase during normal cooking and in which a high pressure state can be easily maintained during pressure cooking. In this case, a pressure display unit and a handle may or may not be provided. (2) The lid body 5 has a pressure indicator 65 that functions as a safety valve. This simplifies the structure of the lid body. In other words, conventional pressure cookers have a valve ball 19 as the second valve means 18 that detaches from the lid body 2 when the pressure exceeds a certain level, which makes the structure complicated. From the perspective of simplifying the structure of the lid body 5, it is sufficient for the lid body to have at least a pressure indicator, and it is not necessary for it to have the communication port 61, and the structure of the pressure adjustment unit is not particularly limited.
