  The operation of the embodiment for carrying out the present invention will be described below.

  When preparing contents such as spaghetti that need to be heated in a range in the container 1 of this embodiment, first prepare raw noodles (contents, not shown) of spaghetti in the container body 2. In addition to serving, a lubricating oil is applied to the bottom of the dish part 3 to deposit a predetermined amount of sauce (other contents) 31 on the dish part 3 and the container body 2 is closed with the spaghetti raw noodles in place. In the state where the plate portion 3 is covered, the lid portion 4 is covered so as to close the plate portion 3 with the source 31 placed, and the plate portion 3 is disposed between the container body 2 and the lid portion 4, the wrap 32 Thus, the container body 2 and the entire lid 4 are wrapped. In addition, the procedure to prepare may cover the empty plate part 3 after putting the spaghetti raw noodles on the container main body 2, and then the sauce 31 and the cover part 4 on the plate part 3.

  Here, the dish part 3 locks the second outer surface 15 of the dish part 3 to the peripheral face 7 of the container body 2 via the locking convex part 20 with respect to the container body 2, and the dish part 3. The back surface of the second step surface 14 is placed on the peripheral surface 7 of the container body 2, and is externally fitted to the container body 2 and fastened. At this time, the first inner side surface 9 of the plate part 3 is spaced inward from the side surface 6 of the container body 2 to form the first flow path gap 33, and the convex part 16 of the plate unit 3 is The second flow path gap 34 is formed away from the peripheral edge surface 7 of the outer wall 2, and the opening 35 is formed away from the side surface 6 of the container body 2. Furthermore, the dish part 3 determines the position of the dish part 3 with respect to the container main body 2 in the circumferential direction by using a mark (not shown) for positioning the convex part 16.

  On the other hand, the lid part 4 makes the third side surface 26 of the lid part 4 abut against the second inner side surface 11 of the dish part 3 with respect to the dish part 3 and the back surface of the groove peripheral surface 25 of the lid part 4 is dished. It is placed on the first step surface 10 of the part 3, and the back surface of the second peripheral surface 27 of the lid part 4 is placed on the peripheral surface 12 of the dish part 3, and is fitted into the dish part 3 and fastened.

  As shown in FIG. 4, the wrap 32 wraps the container body 2 and the lid portion 4 so as to wrap substantially the whole with the dish portion 3 disposed between the container body 2 and the lid portion 4. The upper portion of the lid portion 4 is stretched substantially horizontally from the first peripheral surface 23 and the second peripheral surface 27 so as to separate the door portion 28 via the stepped periphery 29 and the first side surface 22. .

  Next, when eating contents such as spaghetti (not shown), the container body 2 and the lid wrapped by the wrap 32 with the dish part 3 disposed between the container body 2 and the lid part 4 Part 4 is placed in a range and the contents of the spaghetti raw noodles and sauce 31 are heated. At this time, as the spaghetti and the sauce 31 are heated by the range, the internal space 36 between the container body 2 and the dish part 3 and the internal space 37 between the dish part 3 and the lid part 4 are respectively heated to a high vapor pressure. A first flow path gap 33 formed between the container body 2 and the dish part 3, and a pressure such as a high-temperature vapor pressure generated in the internal space 36 between the container body 2 and the dish part 3. It escapes from the second flow path gap 34 and the opening 35 to the outside. At the same time, the pressure such as high-temperature vapor pressure generated in the internal space 37 between the dish portion 3 and the lid portion 4 is pushed upward to open the door portion 28 formed on the lid portion 4, thereby opening the internal space. The pressure of 37 is released from the opening of the door portion 28 to the outside. Here, when the door portion 28 is curved and opened upward so as to relieve pressure, the tip of the door portion 28 does not engage or abut on the lap 32 depending on the arrangement position in the vertical direction with respect to the wrap 32. Further, the wrap 32 that wraps the container body 2 and the lid 4 is appropriately expanded outward by the high-temperature pressure that has escaped to the outside, and does not affect the relief of the pressure.

  Subsequently, after heating the raw spaghetti noodles and the sauce 31 in the range, the container body 2 and the lid part 4 wrapped by the wrap 32 are taken out of the range, the wrap 32 is broken, the lid part 4, the dish part 3, The container main body 2 is removed and the sauce 31 of the dish part 3 is hung on the raw noodles of spaghetti in the container main body 2 so that the spaghetti can be eaten. Here, when the source 31 piled up on the plate part 3 is transferred to the container body 2, the bottom surface 8 and the bottom surface 8 of the plate unit 3, which are smooth surfaces, even if the source 31 is a highly viscous content. It becomes possible to easily transfer the source 31 to the container main body 2 so that the source 31 does not adhere to the bottom surface 8 of the dish portion 3 and remains.

  As described above, according to the present invention, the contents such as raw spaghetti noodles (not shown) and the sauce 31 are heated by the range with the dish portion 3 disposed between the container body 2 and the lid portion 4. At that time, pressure such as vapor pressure is released from the opening 35 formed in the periphery 29 of the plate portion 3 at a high temperature generated in the internal space 36 between the container body 2 and the plate portion 3, and at the lid portion 4. Since the pressure such as the vapor pressure is released at the high temperature generated in the internal space 37 between the plate portion 3 and the lid portion 4 from the door portion 28 that opens upward, each pressure is easily released, and the container 1 can be deformed or damaged. Can be prevented. In addition, since the position where the pressure escapes can be predicted in advance by the opening 35 and the door portion 28, the pressure can be suitably and safely released. Further, since the periphery 29 of the door portion 28 is formed lower than the upper surface 21 of the lid portion 4, even when the door portion 28 opens upward when heated by the range with the lid portion 4 being wrapped by the wrap 32. The tip of the door portion 28 does not engage or abut on the upper lap 32, and the pressure generated in the internal space 37 between the plate portion 3 and the lid portion 4 can be easily released, and the container 1 can be deformed or damaged. Can be prevented. Furthermore, since the door portion 28 is closed except during heating, the hermeticity of the lid portion 4 can be improved and the hygiene level can be improved.

  When the upper surface 21 of the lid portion 4 is formed lower than the first peripheral surface 23 and the second peripheral surface 27 of the lid portion 4, it is lowered in two steps so that the position of the door portion 28 is further lowered. Since the gap is larger than the wrap 32 that wraps the portion 4, when heating by the range with the lid 4 being wrapped by the wrap 32, even if the door portion 28 is opened upward, the tip of the door portion 28 is the upper wrap. The pressure such as the vapor pressure is more easily released at a high temperature generated in the internal space 37 between the plate portion 3 and the lid portion 4 without being engaged with or coming into contact with the plate portion 3, and the container 1 is preferably prevented from being deformed or damaged. can do.

  If four or more open ports 35 are formed at regular intervals in the circumferential direction, the open ports 35 can be arranged in a distributed manner in the circumferential direction. Therefore, steam is generated at a high temperature generated between the container main body 2 and the dish portion 3. Pressure such as pressure can be easily and evenly released.

  If the convex part 16 of the dish part 3 which forms the open port 35 is used as a positioning mark so as to determine the position of the dish part 3 in the circumferential direction, the positional relationship between the container body 2 and the dish part 3, and the dish part 3 And the lid 4 can be easily recognized, so that the container body 2, the lid 4 and the dish 3 can be arranged at desired positions so as to align the left and right positions, thereby enhancing the display effect. Moreover, since the dish part 3 is provided with the latching convex part 20, the dish part 3 can be easily externally fitted to the container body 2. Further, since five or more locking convex portions 20 are provided between the side surfaces of the convex portion 16, the dish portion 3 can be easily detached from the container body 2. In addition, when there are four or less locking convex portions 20 positioned between the convex side surfaces 18, it is difficult to remove.

  If the bottom surface 8 of the dish part 3 is a smooth surface through which the contents can flow, the source 31 can be easily moved by the smooth surface of the dish part 3 when the contents such as the highly viscous source 31 are transferred from the dish part 3. The contents having high viscosity can be suitably transferred.

  When using the container 1, when preparing the contents part such as the source 31 in the dish part 3, a lubricant that can flow the contents such as the source 31 is applied to the bottom surface 8 of the dish part 3 in advance. Therefore, even when the source 31 has a high viscosity, when the source 31 is transferred from the dish part 3, the source 31 having a high viscosity is slid by the lubricating oil on the bottom surface 8 of the dish part 3 and is preferably transferred. be able to.

  In addition, the container of the present invention and the method of using the same are not limited to the above-described embodiments, and the door portion of the lid portion may have any shape as long as it is positioned lower than the upper surface. Good, in particular, the door portion is lowered in two steps through the upper surface from the peripheral edge, but may be further lowered in multiple steps, the contents are not limited to food, and may be industrial materials, etc. Of course, various changes can be made without departing from the scope of the present invention.
