It will be explained in.

<Container configuration and function of the first embodiment>
First, the container 10 of the present embodiment will be described with reference to FIGS. 1 and 2.
As shown in FIGS. 1 and 2, the container 10 includes a container body 20 and a lid 30. In the present embodiment, the container body 20 and the lid 30 are made of resin as an example. The container 10 is adapted to accommodate foodstuffs (not shown) as an example in the space SP formed by the container body 20 and the lid 30. Then, the foodstuff contained in the container 10 is heated by a microwave oven (not shown) as an example and processed into food (in other words, the foodstuff), as described in the method for producing food (not shown) described later. Is heat-treated and cooked into food).

The container body 20 has a peripheral wall 22 and a bottom wall 24. The peripheral wall 22 has a cylindrical shape as an example, and has a shape substantially symmetrical with respect to its axis (axis O in the drawing to be referred to). The bottom wall 24 is a disk connected to the entire peripheral edge of one end of the peripheral wall 22 in the axial direction. That is, the container body 20 is, for example, a bottomed cylinder. An opening OP is formed on the upper side of the bottom wall 24 (the other end side of the peripheral wall 22 in the axial direction).

The lid 30 has a top plate 32 and a peripheral side wall 34. The top plate 32 is a disk as an example. The peripheral side wall 34 is a cylindrical wall connected to the entire peripheral edge of the top plate 32. Then, as shown in FIG. 2, the lid 30 is fitted into the container body 20 with the outer peripheral surface of the peripheral side wall 34 facing the inner peripheral surface of the peripheral wall 22 of the container body 20 to close the opening OP. ing. As a result, the lid 30 forms a space SP (see FIG. 2) surrounded by the container main body 20.

Next, the portion where the container body 20 and the lid 30 fit together will be described with reference to FIGS. 2 and 3.
In the present embodiment, the lid 30 is configured to fit inside the container body 20. Specifically, the portion of the peripheral wall 22 of the container body 20 that is fitted to the lid 30 (hereinafter, referred to as the first portion 25) is formed in a ring shape having a peripheral surface along the axis. On the other hand, the portion of the peripheral side wall 34 of the lid 30 that fits into the first portion 25 (hereinafter referred to as the second portion 35) is formed in a ring shape having a peripheral surface along the axis. The inner diameter of the first portion 25 and the outer diameter of the second portion 35 are set so that the second portion 35 fits inside the first portion 25.

Then, as shown in FIG. 2, in a state where the lid 30 fits into the container body 20 and is supported by the container body 20, the second portion 35 is supported from below by the step portion 26. With the above configuration, the second portion 35 can move in the vertical direction on the upper side of the step portion 26 of the first portion 25 with respect to the first portion 25.
Further, as shown in FIG. 3, a through hole 36 is formed in the second portion 35. As an example, the through hole 36 is a rectangular hole whose longitudinal direction is the axial direction.

The above is the description of the configuration and function of the container 10 of the first embodiment.

<Method of producing food using the container of the first embodiment>
Next, a method for producing food using the container 10 of the present embodiment will be described mainly with reference to FIG.
First, a food material (for example, vegetables) is stored in the container body 20, and the opening OP of the container body 20 is closed with a lid 30 (see FIGS. 1 and 2). In this case, the container body 20 may contain foodstuffs below vegetables. For example, water, seasonings (soy sauce, salt, pepper, sake, mirin, curry powder, oil, etc.) and other ingredients may be added.
Next, the container 10 containing the foodstuff is placed in a heating device (not shown, a microwave oven as an example) to heat the foodstuff. Here, an example of the heating device is a microwave oven, but the heating device does not have to be a microwave oven as long as the food can be heated. The figures on the left side of FIGS. 4A and 4B show the state at the start of heating. Along with this, water vapor is generated from the foodstuffs stored in the space SP of the container 10, and the pressure of the space SP increases. Then, when the force for raising the lid 30 due to the pressure of the space SP becomes larger than the own weight of the lid 30, the lid 30 rises upward in the vertical direction while being guided by the first portion 25. The central figure of FIGS. 4A and 4B shows a state in which the lid 30 is raised. When a part of the through hole 36 formed in the second portion 35 exceeds the upper end of the first portion 25, the part of the through hole 36 communicates the space SP with the space outside the container 10. As a result, a part of the water vapor in the space SP is discharged to the outside of the container 10 through a part of the through hole 36. The figures on the right side of FIGS. 4A and 4B show a state in which more water vapor is generated in the space SP and the pressure in the space SP is further increased. In this state, the lower end of the through hole 36 exceeds the upper end of the first portion 25, and more water vapor is discharged to the outside of the container 10.
Here, FIG. 5 is a graph showing the relationship between the ascending distance of the lid 30 and the opening area depending on the position of the through hole 36 in the container 10 of the present embodiment. As shown in FIG. 3B, since the through hole 36 has a rectangular shape whose longitudinal direction is along the axial direction, the opening area increases in proportion to the ascending distance of the lid 30. Further, FIG. 6 shows the rate of change (differential coefficient) between the ascending distance of the lid 30 and the opening area of the portion of the container 10 of the present embodiment that communicates the space SP in the container 10 and the outside of the container 10 with respect to the ascending distance. It is a graph which shows the relationship with. In the case of this embodiment, since the graph of FIG. 5 shows the relationship of the linear function, the rate of change, that is, the differential coefficient is constant as a positive integer.
When the pressure in the space SP decreases with the discharge of water vapor, the lid 30 descends downward in the vertical direction while being guided by the first portion 25. The lid 30 is moved in the vertical direction by the pressure inside the space SP, so that the amount of water vapor discharged is appropriately adjusted and the foodstuff is heated.
Then, the food material heated for a predetermined period becomes food, and the food production method of the present embodiment is completed.

In the case of the present embodiment, when the through hole 36 formed in the first portion 25 and the through hole 36 formed in the second portion 35G overlap in the radial direction, the space SP of the container 10G and the outside of the container 10G are exposed to each other. Communicate.
The effect of this embodiment is the same as that of the sixth embodiment.
The above is the description of the eighth embodiment.

As described above, each of the above-described embodiments has been described as an example of the present invention, but the present invention is not limited to each of the above-described embodiments. The technical scope of the present invention also includes, for example, the following forms (modifications). In the following modifications, the components having the same structure and function as in each embodiment will be described using the same names and symbols as in each embodiment. Further, the components having different structures and the same functions as in the case of each embodiment will be described using the same names and the same code numbers with alphabets as in the case of each embodiment.

For example, in the description of the first embodiment, it is assumed that the container 10 is made of resin. However, one or both of the container body 20 and the lid 30 constituting the container 10 do not have to be made of resin. For example, one may be made of another material such as rubber or metal.

Further, in the description of the second embodiment, the shape of the through hole 36A is assumed to be triangular. However, as in the through hole 36H of the modified example shown in FIG. 17, it may be composed of a plurality of through holes and may have a triangular shape as a whole.

Further, in the description of the first embodiment, it has been described that the opening for communicating the space SP of the container 10 and the outside of the container 10 is formed by the through hole 36. However, as in the modified example shown in FIG. 18, the notch 36I may be used instead of the through hole 36. Further, as in this modification, the opening may be composed of a plurality of notches 36I. This point is the same in the case of the through hole 36 and the like.

Further, in the description of the first embodiment, it is assumed that the through hole 36 is formed at one place in the circumferential direction of the container 10. However, as in the modified example shown in FIG. 19, the portion X in which the through hole 36 or the notch 36I is formed may be a plurality of portions in the circumferential direction of the container 10. In this case, if there are two places where the through holes 36 are formed, it is preferable that the through holes 36 are formed symmetrically with respect to the axis O (for example, point symmetry). In the case of this modification, the lid 30 due to the change in air pressure in the space SP is compared with the configuration in which the through holes 36, 36A or the notch 36I are formed only in one place of the first portion 25 or the second portion 35. It is effective in that it can smooth the movement of.
If there are three places where the through holes 36 or the notches 36I are formed, it is preferable that the through holes 36 are formed at equal intervals in the circumferential direction (see the modified example shown in FIG. 20). .. Similarly, if there are four places where the through holes 36 or the notches 36I are formed, it is preferable that the through holes 36 are formed at equal intervals in the circumferential direction (see the modified example shown in FIG. 21). ).

Further, as in the first embodiment, when the container 10 has a symmetrical shape with respect to the axis O, specifically, when the container body 20 and the lid 30 have a circular shape when viewed from the axial direction, it is shown in FIG. Like the container body 20J and the lid 30J of the container 10J of the modified example, the protrusion 50 (an example of the circumferential regulation part) is on one of the first portion 25J of the container body 20J and the second portion 35J of the lid 30J, and the protrusion 50 is on the other. There may be a dent 60 (another example of the circumferential regulation portion) into which the dent 60 is fitted. In the case of this modification, one of the peripheral wall 22 and the lid 30J is restricted from moving in the circumferential direction by fitting the protrusion 50 into the recess 60.
The container 10 may not have a circular shape when viewed from the axial direction, for example, may have a polygonal shape. In this case, it can be said that the shape has the function of the circumferential regulation unit.

Further, a container set (illustrated) in which a container 10 or the like of each embodiment or each modification and a lid (an example of another lid) having a through hole 36 or the like having a shape different from that of the lid 30 provided in the container are combined. Omitted) is also included in the technical scope of the present invention. In the case of this modification, it is effective in that the heating conditions of the foodstuff can be changed according to the type of the lid, or the type of the lid can be changed according to the type of the foodstuff.

It should be noted that one form of each of the above-described embodiments and modifications may be combined with components of another form. Further, it may be a form in which some components of one form of each of the above-described embodiments and modifications are replaced with components of another form.
