Description

[Technical field]

[0001] The present invention relates to a container comprising a container body, an inner lid, and a lid body attached to cover the inner lid. [Background technology]

[0002] Conventionally, containers consisting of a container body, an inner lid, and a lid body covering the inner lid, as shown in Patent Document 1, have been known, and the inner lid has a handle to make it easier to remove the inner lid from the container body. The handle of the inner lid can be inserted into a part of the lid body so that the inner lid and the lid body covering the inner lid can be lifted together. However, the handle of the inner lid has a protruding shape with a certain thickness so that it can be lifted together with a part of the lid body. Therefore, there was a problem that the handle narrowed the space for storing food on the inner lid.

[0003] The container shown in Patent Document 2 is also a container consisting of a container body, an inner lid, and a lid body that covers the inner lid, and the inner lid is provided with a handle to make it easier to hold the inner lid. The handles of the inner lid are recessed from the surface of the inner lid at both ends, and fingers can be hooked into the recessed parts. However, the handles are recessed to a size large enough for fingers to fit in. Therefore, there is a problem in that the handles narrow the space on the inner lid for storing food.

[0004] [Patent Document 1] Patent Publication 2019-14501 [Patent Document 2] Patent Publication No. 2017-145043 Summary of the Invention [Problem to be solved by the invention]

[0005] In view of the above problems, the present invention provides a container that includes a container body, an inner lid, and a lid body, that can increase the space for storing food above the inner lid, and that has a handle that is easy to grasp. [Means for solving the problem]

[0006] In order to solve the above problem, the container of claim 1 of the present invention is a container comprising a container body, an inner lid that fits internally into the lower container side fitting portion of the container body, and a lid body that fits internally into the upper container side fitting portion of the container body, wherein the inner lid has a sheet-like handle, and when the inner lid is fitted internally into the lower container side fitting portion of the container body, there is a gap between the handle and the side wall of the container body.

[0007] According to the above feature, since the handle is sheet-shaped, the space for storing food ingredients on the bottom wall is not narrowed, and a large amount of food ingredients can be stored efficiently.

[0008] Furthermore, when the inner lid is fitted into the container side fitting portion on the lower side of the container body, the handle is separated from the side wall of the container body to form a gap, which allows a finger to be inserted into the gap and the handle to be easily picked up.

[0009] Furthermore, the container according to claim 1 of the present invention is characterized in that the handle is a vertical wall portion extending upward in a long shape along the outer edge of the inner lid.

[0010] According to the above feature, the area that can be gripped by a person's fingers is increased, making it easier to pick up the handle.

[0011] moreover, The present inventionThe container according to the present invention is characterized in that the handle is flexible, and when the inner lid is not fitted into the lower container-side fitting portion of the container body, the handle is in a substantially horizontal outward position, and when the inner lid is fitted into the lower container-side fitting portion of the container body, the handle is bent at a bent portion and rises upward, with a gap between the tip of the handle and the side wall of the container body.

[0012] According to the above-mentioned features, when the inner lid is fitted into the container side fitting portion on the lower side of the container body, the handle is bent at the bending portion and raised upward, so that the handle can be easily picked up by inserting finger F2 into the gap from above.

[0013] moreover, The present invention The container according to the present invention is characterized in that a recess is formed in a part of the handle, and the bottom surface of the recess abuts against the side wall of the container body.

[0014] According to the above feature, when picking up the handle, the fingers can fit inside the recess, making it easy to pick up the handle. Effect of the Invention

[0015] As described above, the container of the present invention allows for a large space for storing food on the inner lid and has an easy-to-grasp handle. [Brief description of the drawings]

[0018] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In this specification, "upward" refers to a direction toward the top in the vertical direction when the container body of the container is placed on a horizontal surface with the opening side facing up, "downward" refers to a direction toward the bottom in the vertical direction, "horizontal" refers to a direction toward the horizontal direction, and "vertical" refers to a direction perpendicular to "horizontal" on a horizontal surface.

[0019] First, Fig. 1 and Fig. 2 show a lid 100 of a container 500 of the present invention. Fig. 1(a) is a plan view of the lid 100, Fig. 1(b) is a side view of the lid 100, Fig. 2(a) is an AA end view of Fig. 1(a), and Fig. 2(b) is an enlarged end view of the part surrounded by a dotted line in Fig. 2(a).

[0020] As shown in Fig. 1 and Fig. 2, the lid 100 is a shallow dish type opening downward, has a generally circular shape in a plan view, and includes a flat top plate 110, a side wall 120 continuing downward from an edge 111 of the top plate 110, and an inner fitting portion 130 provided at the lower end of the side wall 120. A protrusion 112 protruding upward from the top plate 110 is formed at the edge 111 of the top plate 110, and the bottom wall of a container body described later can be disposed inside this protrusion 112. Therefore, when the containers 500 are stacked, the bottom wall of the container body of the container 500 stacked on top is surrounded by the protrusion 112 of the lid 100 of the container 500 in the lower layer, so that the container 500 in the upper layer does not slip and fall, and can be stably stacked. The side wall 120 and the inner fitting portion 130 are provided continuously or discontinuously over the entire circumferential direction of the lid body 100 .

[0021] As shown in FIG. 2(b), the lower and upper sides of the inner fitting portion 130 are provided with a lower arc portion 140 and an upper arc portion 150, each of which has an arc-shaped vertical cross section. A flat portion 131 extending laterally from the lower end 141 of the lower arc portion 140 is provided at the lower end 141, and the flat portion 131 is continuous with the lower end 121 of the side wall 120. A flat portion 132 extending laterally from the upper end 152 of the upper arc portion 150 is also provided at the upper end 152. The vertical cross section is a cross section that appears when the inner fitting portion 130 is cut by a plane that intersects at a right angle with the opening surface of the lid body 100, as shown in FIG. 2. The inner fitting portion 130 includes both the flat portion 131 and the flat portion 132, but is not limited thereto, and may include only one of the flat portion 131 or the flat portion 132.

[0022] 2(b), the upper arc portion 150 has an arc shape with a radius R1 and a central angle θ1, and similarly, the lower arc portion 140 has an arc shape with a radius R2 and a central angle θ2. The upper arc portion 150 is formed to describe a larger arc than the lower arc portion 140, and the length L1 of the upper arc portion 150 is longer than the length L2 of the lower arc portion 140.

[0023] Furthermore, the central angle θ1 of the upper arc portion 150 is greater than 90 degrees (i.e., 90°<θ1). By making the central angle θ1 of the upper arc portion 150 greater than 90 degrees in this way, the fit with the container side fitting portion described below becomes stronger. On the other hand, the central angle θ2 of the lower arc portion 140 is less than 90 degrees (i.e., θ2≦90°). By making the central angle θ2 of the lower arc portion 140 less than 90 degrees in this way, the so-called undercut portion is reduced when the lid body 100 is sheet-molded, so that the lid body 100 becomes easier to remove from the mold.

[0024] In addition, the lower arc portion 140 and the upper arc portion 150 are connected by the intermediate portion 133 in a state of being vertically spaced apart. Specifically, the upper end 142 of the lower arc portion 140 is continuous with the intermediate portion 133, and the lower end 151 of the upper arc portion 150 is continuous with the intermediate portion 133, so that the lower arc portion 140 and the upper arc portion 150 are vertically spaced apart via the intermediate portion 133. In this way, the lower arc portion 140 and the upper arc portion 150 are not directly continuous with each other, and are spaced apart from each other via the intermediate portion 133, so that the sealing property of the inner fitting portion 130 can be more reliably maintained. For example, when an external force is applied to the edge of the lid body 100, the upper arc portion 150 located on the edge side may be deformed, but the lower arc portion 140 is not easily deformed because it is spaced from the upper arc portion 150 by the intermediate portion 133. Therefore, even if an external force is inadvertently applied to the edge of the lid 100, the inner fitting portion 130 as a whole maintains a sealing performance.

[0025] Furthermore, a recess 134 is provided between the lower arcuate portion 140 and the upper arcuate portion 150 so as to be constricted inward from the arcuate surfaces of the lower arcuate portion 140 and the upper arcuate portion 150. Therefore, as described later, the area where the inner fitting portion 130 comes into close contact with the container side fitting portion described later is increased, and the seal Although the recess 134 is provided between the lower arc portion 140 and the upper arc portion 150, the present invention is not limited to this, and a protrusion may be provided to increase the contact area.

[0026] Although the length L1 of the upper arc portion 150 is longer than the length L2 of the lower arc portion 140, the present invention is not limited to this, and the length L1 of the upper arc portion 150 and the length L2 of the lower arc portion 140 may be the same, or the length L1 of the upper arc portion 150 may be shorter than the length L2 of the lower arc portion 140. However, by making the length L1 of the upper arc portion 150 longer than the length L2 of the lower arc portion 140, even if an external force is applied to the edge of the lid body 100, the upper arc portion 150 located on the edge side can continue to fit firmly into the container body side due to its longer overall length, so that it is possible to effectively prevent the lid body 100 from being inadvertently removed. In the lid body 100 shown in Figures 1 and 2, the internal fitting portion 130 is configured to have a lower arc portion 140 and an upper arc portion 150, but this is not limited to this, and other configurations may be adopted, such as a configuration having an inverted tapered internal fitting portion, as long as the internal fitting portion 130 of the lid body 100 can be internally fitted into the lower container side fitting portion of the container body 400.

[0027] Next, Fig. 3 shows the inner plate 200 of the container 500 of the present invention. Fig. 3(a) is a plan view of the inner plate 200, Fig. 3(b) is a side view of the inner plate 200, and Fig. 3(c) is a BB end view.

[0028] 3, the inner plate 200 is a shallow plate type that opens upward and has a generally circular shape in a plan view, and is provided with a flat bottom wall 210, a side wall 220 that continues to rise upward from the edge of the bottom wall 210, and a partition wall 221 for individually storing ingredients and the like. Furthermore, on the outside of the side wall 220, a skirt portion 230 is provided that extends downward from the upper end of the side wall 220, and a flange portion 240 is provided that extends generally horizontally from the lower end of the skirt portion 230. The side wall 220, the skirt portion 230, and the flange portion 240 are provided continuously or intermittently around the entire circumference of the inner plate 200 in the circumferential direction.

[0029] 3, inner plate 200 is provided with recess 250 recessed inward from the outer edge of inner plate 200. Recess 250 is sized to accommodate a handle of an inner lid, which will be described later. Food such as condiments and vegetables can be stored in the space partitioned by partition wall 221 on bottom wall 210, and bottom wall 210 is provided with finely uneven anti-slip surface 211 to prevent the stored food from slipping.

[0030] Next, Fig. 4 and Fig. 5 show the inner lid 300 of the container 500 of the present invention. Fig. 4(a) is a plan view of the inner lid 300, Fig. 4(b) is a side view of the inner lid 300, Fig. 5(a) is a CC end view of Fig. 4(a), Fig. 5(b) is an enlarged end view of the part surrounded by the dotted line on the right side in Fig. 5(a), and Fig. 5(c) is an enlarged end view of the part surrounded by the dashed line on the left side in Fig. 5(a).

[0031] 4 and 5, the inner lid 300 is a shallow dish-shaped lid that opens upward and has a generally circular shape in a plan view, and includes a flat bottom wall 310, a handle 320 that protrudes upward from the bottom wall 310, and an inner fitting portion 330 provided on an outer edge 312 of the bottom wall 310. The bottom wall 310 has a recess 315 at its center for accommodating noodles and the like. The inner fitting portion 330 is provided continuously or intermittently around the entire circumference of the inner lid 300 in the circumferential direction. The outer edge 312 of the bottom wall 310 is provided with a rotation stopper 314 that protrudes outward.

[0032] A through hole 311 is formed at the center O of the inner lid 300, penetrating the bottom wall 310. As described below, the inner lid 300 is used to allow air to escape, as the lower side of the container body is filled with liquid such as soup and covered with the inner lid 300. The handle 320 has a generally triangular pyramid shape when viewed from the side, and is thin-walled so that it can be easily picked up with human fingers. Furthermore, the inner surface 321 and the outer surface 322 of the handle 320 are curved, making it easy to pick up with fingertips. The handle 320 is disposed at a position shifted from the center O of the inner lid 300 toward the outer edge 312 of the inner lid 300. A hinge (bending portion) 313 extending linearly is provided on the inside of the handle 320. The hinge 313 is configured as a groove linearly provided in the bottom wall 310, and by lifting the handle 320, the bottom wall 310 around the handle 320 can be bent upward from the hinge 313 as a starting point. The hinge 313 is in the form of a linear groove, but is not limited to this, and may be in any other form as long as the bottom wall 310 around the handle 320 can be bent upward from the hinge 313 as a starting point.

[0033] The inner fitting portion 330 of the inner lid 300 has a configuration basically the same as that of the inner fitting portion 130 of the lid body 100, and the lower and upper sides of the inner fitting portion 330 are provided with a lower arc portion 340 and an upper arc portion 350, each of which has an arc-shaped vertical cross section. A flat portion 331 extending laterally from the lower end 341 of the lower arc portion 340 is provided at the lower end 341, and the flat portion 331 is continuous with the bottom wall 310. A flat portion 332 extending laterally from the upper end 352 of the upper arc portion 350 is also provided at the upper end 352 of the upper arc portion 350. The vertical cross section is a cross section that appears when the inner fitting portion 330 is cut by a plane that intersects the bottom wall 310 at a right angle, as shown in FIG. 5. Further, the inner fitting portion 330 includes both the flat portion 331 and the flat portion 332, but is not limited to this.

[0034] 5, upper arc portion 350 has an arc shape with radius R3 and central angle θ3, and similarly, lower arc portion 340 has an arc shape with radius R4 and central angle θ4. Upper arc portion 350 is formed to describe a larger arc than lower arc portion 340, and length L3 of upper arc portion 350 is longer than length L4 of lower arc portion 340.

[0035] Furthermore, the central angle θ3 of the upper arc portion 350 is greater than 90 degrees (i.e., 90°<θ3). By making the central angle θ3 of the upper arc portion 350 greater than 90 degrees in this way, the fit with the container side fitting portion described below becomes stronger. On the other hand, the central angle θ4 of the lower arc portion 340 is less than 90 degrees (i.e., θ4≦90°). By making the central angle θ4 of the lower arc portion 340 less than 90 degrees, the so-called undercut portion is reduced when the inner lid 300 is sheet-molded, so that the inner lid 300 becomes easier to remove from the mold.

[0036] In addition, the lower arc portion 340 and the upper arc portion 350 are connected by the intermediate portion 333 in a state of being vertically spaced apart. Specifically, the upper end 342 of the lower arc portion 340 is continuous with the intermediate portion 333, and the lower end 351 of the upper arc portion 350 is continuous with the intermediate portion 333, so that the lower arc portion 340 and the upper arc portion 350 are vertically spaced apart via the intermediate portion 333. In this way, the lower arc portion 340 and the upper arc portion 350 are not directly continuous with each other, and are spaced apart from each other via the intermediate portion 333, so that the sealing property of the inner fitting portion 330 can be more reliably maintained. For example, when an external force is applied to the outer edge 312 of the inner lid 300, the upper arc portion 350 located on the outer edge side may be deformed, but the lower arc portion 340 is not easily deformed because it is spaced from the upper arc portion 350 by the intermediate portion 333. Therefore, even if an external force is inadvertently applied to the outer edge of the inner lid 300, the inner fitting portion 330 as a whole maintains a sealing performance.

[0037] Furthermore, a recess 334 is provided between the lower arc portion 340 and the upper arc portion 350, as if it is narrowed inward from the arc surfaces of the lower arc portion 340 and the upper arc portion 350. Therefore, as described below, the area where the inner fitting portion 330 comes into close contact with the container side fitting portion described below increases, and the sealing performance becomes higher. Note that, although the recess 334 is provided between the lower arc portion 340 and the upper arc portion 350, the present invention is not limited to this, and a protrusion may be provided to increase the contact area. stomach.

[0038] Although the length L3 of the upper arc portion 350 is longer than the length L4 of the lower arc portion 340, this is not limited to this, and the length L3 of the upper arc portion 350 and the length L4 of the lower arc portion 340 may be the same length, or the length L3 of the upper arc portion 350 may be shorter than the length L4 of the lower arc portion 340.

[0039] Furthermore, the inner fitting portion 330 is provided around the entire outer edge 312 of the inner lid 300, but the fitting strength of the inner fitting portion 330 located on the outside of the handle 320 of the inner lid 300 is configured to be weaker than the fitting strength of the inner fitting portion 330' located on the opposite side to the outside of the handle 320. Note that since the inner fitting portion 330' has basically the same configuration as the inner fitting portion 330 located on the handle 320 side, each component of the inner fitting portion 330' is represented by adding "'" to the reference numeral of each component of the inner fitting portion 330, and detailed description of the same configuration will be omitted.

[0040] As shown in FIG. 5(b), the central angle of the upper arcuate portion 350 of the inner fitting portion 330 located on the handle 320 side is θ3, and as shown in FIG. 5(c), the central angle of the upper arcuate portion 350' of the inner fitting portion 330 located on the opposite side of the handle 320 is θ3'. The central angle θ3 of the upper arcuate portion 350 of the inner fitting portion 330 located on the handle 320 side is slightly smaller than the central angle θ3' of the upper arcuate portion 350' of the inner fitting portion 330' located on the opposite side of the handle 320. Therefore, when the inner fitting portion 330 of the inner lid 300 is fitted into the container-side fitting portion of the container body described later, the upper arcuate portion 350 having the smaller central angle θ3 will be fitted shallower into the container-side fitting portion than the upper arcuate portion 350' on the opposite side. Therefore, the fitting strength of the inner fitting portion 330 located on the outer side of the handle 320 of the inner lid 300 is weaker than the fitting strength of the inner fitting portion 330' located on the opposite side to the outer side of the handle 320.

[0041] In the inner lid 300 shown in FIG. 5, the central angle θ3 of the upper arcuate portion 350 of the inner fitting portion 330 located on the handle 320 side is made smaller than the central angle θ3' of the upper arcuate portion 350' of the inner fitting portion 330' located on the opposite side, and the undercut amount of the upper arcuate portion 350 of the inner fitting portion 330 located on the handle 320 side is made smaller than the undercut amount of the upper arcuate portion 350' of the inner fitting portion 330' located on the opposite side. However, the present invention is not limited to this. If the fitting strength of inner fitting portion 330 located on the outside of handle 320 can be configured to be weaker than the fitting strength of inner fitting portion 330' located on the opposite side of the outside of handle 320, any appropriate configuration can be adopted, such as, for example, changing the shape of upper arc portion 350 located on the handle 320 side to make the fitting area between upper arc portion 350 and the container side fitting portion smaller than the fitting area between upper arc portion 350' located on the opposite side of handle 320 and the container side fitting portion.

[0042] In the inner lid 300 shown in Figures 4 and 5, the inner fitting portion 330 has a configuration including a lower arc portion 340 and an upper arc portion 350, but this is not limited to this, and other configurations may be adopted, such as a configuration including a reverse tapered inner fitting portion, as long as the inner fitting portion 330 of the inner lid 300 can be fitted into the lower container side fitting portion of the container body 400.

[0043] Next, Fig. 6 and Fig. 7 show the container body 400 of the container 500 of the present invention. Fig. 6(a) is a plan view of the container body 400, Fig. 6(b) is a side view of the container body 400, Fig. 7(a) is a DD end view of Fig. 6(a), and Fig. 7(b) is an enlarged end view of the part surrounded by the dotted line in Fig. 7(a).

[0044] As shown in Figures 6 and 7, the container body 400 is deep dish-shaped and opens upward, has a roughly circular shape when viewed from above, and is equipped with a flat bottom wall 410, a side wall 420 that continues upward from the edge 411 of the bottom wall 410, a container side fitting portion 430 provided on the inside of the lower side of the side wall 420, and a container side fitting portion 460 provided on the inside of the upper side of the side wall 420. A storage section 403 surrounded by a bottom wall 410 and a side wall 420 is formed on the lower side of the container body 400, and is capable of storing food such as liquid. The side wall 420, the container side fitting section 430 on the lower side, and the container side fitting section 460 on the upper end side are provided continuously or intermittently all around the circumferential direction of the container body 400. In addition, a knob section 402 that protrudes outward is provided on the outer edge 401 of the container body 400.

[0045] The container side fitting portion 430 on the lower side of the container body 400 is adapted to fit the inner lid 300, and the shape of the container side fitting portion 430 and the shape of the inner fitting portion 330 of the inner lid 300 are the same. Specifically, a lower arc portion 440 having an arc-shaped vertical section and an upper arc portion 450 having an arc-shaped vertical section are provided on the lower side and upper side of the container side fitting portion 430, respectively. The lower arc portion 440 has the same shape as the lower arc portion 340 of the inner fitting portion 330 of the inner lid 300 so that it can be closely fitted to the lower arc portion 340 of the inner fitting portion 330 of the inner lid 300. The upper arc portion 450 has the same shape as the upper arc portion 350 so that it can be closely fitted to the upper arc portion 350 of the inner fitting portion 330 of the inner lid 300. In addition, the intermediate portion 433 that vertically connects the lower arc portion 440 and the upper arc portion 450 has the same shape as the intermediate portion 333 of the inner fitting portion 330 so that it can be in close contact with the intermediate portion 333 of the inner fitting portion 330. In this way, the container side fitting portion 430 on the lower side of the container body 400 is configured to be in close contact with the inner fitting portion 330 of the inner lid 300 and be fitted thereto. Note that the shape of the container side fitting portion 430 and the shape of the inner fitting portion 330 of the inner lid 300 matching is not limited to the case where the two shapes match so as to be completely in close contact with each other without any gaps, but also includes the case where the shape of the container side fitting portion 430 and the shape of the inner fitting portion 330 of the inner lid 300 are slightly different from each other as long as they can be sealed to prevent liquid leakage when the inner fitting portion 330 of the inner lid 300 is internally fitted into the container side fitting portion 430 of the container body 400.

[0046] Further, a flat portion 431 extending laterally from the lower end 441 of the lower arc portion 440 is provided at the lower end 441, and this flat portion 431 is continuous with the lower side wall 420. Meanwhile, a flat portion 432 extending laterally from the upper end 452 of the upper arc portion 450 is also provided at the upper end 452 of the upper arc portion 450, and this flat portion 432 is continuous with the upper side wall 420. The flat portion 431 of the container side fitting portion 430 is configured so as to be able to closely contact the flat portion 331 of the inner fitting portion 330 of the inner lid 300, and the flat portion 432 of the container side fitting portion 430 is also configured so as to be able to closely contact the flat portion 332 of the inner fitting portion 330 of the inner lid 300.

[0047] The container side fitting portion 460 on the upper side of the container body 400 is adapted to fit the lid body 100 therein, and the shape of the container side fitting portion 460 and the shape of the inner fitting portion 130 of the lid body 100 are the same. Specifically, a lower arc portion 470 having an arc-shaped vertical section and an upper arc portion 480 having an arc-shaped vertical section are provided on the lower side and the upper side of the container side fitting portion 460, respectively. The lower arc portion 470 has the same shape as the lower arc portion 140 so that it can be closely fitted to the lower arc portion 140 of the inner fitting portion 130 of the lid body 100. The upper arc portion 480 has the same shape as the upper arc portion 150 so that it can be closely fitted to the upper arc portion 150 of the inner fitting portion 130 of the lid body 100. In addition, the intermediate portion 463 connecting the lower arc portion 470 and the upper arc portion 480 vertically has the same shape as the intermediate portion 133 of the inner fitting portion 130 so as to be in close contact with the intermediate portion 133 of the inner fitting portion 130. In this way, the container side fitting portion 460 on the upper side of the container body 400 is configured to be in close contact with the inner fitting portion 130 of the lid body 100 and be fitted thereto. Note that the shape of the container side fitting portion 460 and the shape of the inner fitting portion 130 of the lid body 100 matching is not limited to the case where both shapes match so as to be completely in close contact with each other without any gaps, but also includes the case where the shape of the container side fitting portion 460 and the shape of the inner fitting portion 130 of the lid body 100 are slightly different from each other as long as they can be sealed to prevent liquid leakage when the inner fitting portion 130 of the lid body 100 is internally fitted into the container side fitting portion 460 of the container body 400.

[0048] A flat portion 461 is provided at the lower end 471 of the lower arc portion 470, and extends laterally from the lower end 471. The flat portion 461 is continuous with the side wall 420 on the upper stage side. Meanwhile, a flat portion 462 extending laterally from the upper end 482 of the upper arc portion 480 is also provided at the upper end 482. The flat portion 461 of the container side fitting portion 460 is configured so as to be able to closely contact the flat portion 131 of the inner fitting portion 130 of the lid body 100, and the flat portion 462 of the container side fitting portion 460 is also configured so as to be able to closely contact the flat portion 132 of the inner fitting portion 130 of the lid body 100.

[0049] 6(a), a storage section 421 is provided in a portion of the side wall 420 between the lower container side fitting section 430 and the upper container side fitting section 460, the storage section 421 being recessed outward as if the side wall 420 had been cut out. The storage section 421 is continuous with the flat section 432 of the container side fitting section 430, and can accommodate the anti-rotation stopper 314 of the inner lid 300 internally fitted into the container side fitting section 430.

[0050] The lid body 100, the inner plate 200, the inner lid 300, and the container body 400 according to this embodiment are formed by sheet molding (for example, vacuum molding, pressure molding, hot plate molding) using a sheet-like material having a thickness of about 0.1 mm to 1.0 mm. For example, the lid body 100, the inner plate 200, and the container body 400 can be made of polystyrene, polypropylene, polystyrene, A-PET, polylactic acid, or biaxially stretched versions of these, and the inner lid 300 can be made of polystyrene, polypropylene, polystyrene, A-PET, polylactic acid, or foamed versions of these or versions mixed with talc. The lid body 100, the inner plate 200, the inner lid 300, and the container body 400 are generally circular in plan view, but can be appropriately changed in shape to other shapes such as polygonal in plan view.

[0051] Next, a method of storing food in container 500 of the present invention will be described with reference to Figures 8 and 9. Figure 8 is an exploded side view of container 500 of the present invention, Figure 9(a) is a plan view of inner lid 300 fitted inside container body 400, and Figure 9(b) is a plan view of inner lid 300 fitted inside container body 400 with inner plate 200 placed over inner lid 300.

[0052] Here, for example, when storing foodstuffs such as chilled noodles in the container 500, first fill the lower storage section 403 of the container body 400 with liquid such as chilled noodle soup and store it therein, as shown in FIG. 8. The liquid is stored up to the lower part of the container side fitting section 430 of the container body 400 with a certain amount of margin so as not to exceed the container side fitting section 430 of the container body 400. In this state, in order to seal the storage section 403, the inner lid 300 is internally fitted into the container side fitting section 430 from above the storage section 403. As shown in FIG. 9(a), when the inner lid 300 is internally fitted into the container body 400, the position of the inner lid 300 is adjusted so that the rotation stopper 314 of the inner lid 300 is stored in the storage section 421 of the container body 400. By storing the rotation stopper 314 in the storage section 421, the effect of preventing the inner lid 300 from rotating inside the container body 400 can be obtained.

[0053] Next, food ingredients such as cold noodles are placed on the bottom wall 310 of the inner lid 300. Then, the inner plate 200 is placed so as to cover the inner lid 300. Specifically, as shown in FIG. 9(b), the flange portion 240 of the inner plate 200 is placed on the flat portion 461 of the upper stage of the container body 400, and the inner plate 200 is placed in the container body 400. In addition, the position of the inner plate 200 is adjusted so that the tip of the handle 320 of the inner lid 300 protrudes from the recess 250 of the inner plate 200. By the handle 320 protruding from the recess 250, a rotation prevention effect can be obtained so that the inner plate 200 does not rotate in the container body 400. Furthermore, by the tip of the handle 320 protruding from the recess 250, the food such as noodles stored on the inner lid 300 does not come into contact with the tip side of the handle 320. Therefore, food and the like does not adhere to the tip side of handle 320, so that the user who holds handle 320 does not feel uncomfortable and it is hygienic.

[0054] Next, food such as condiments for cold noodles is placed on the bottom wall 210 of the inner plate 200, which is partitioned by the partition wall 221. Then, the lid 100 is fitted into the container side fitting portion 460 of the container body 400 so as to cover the inner plate 200 and seal it. The containers 500 in which each ingredient of the cold noodles is individually housed and sealed are displayed in stores for sale.

[0055] The sealed state of the container 500 will now be described with reference to Fig. 10. Fig. 10 is a vertical end view of the container 500 in a sealed state. The vertical end view of the container 500 in Fig. 10 is an end view showing both ends of the container 500 in an enlarged manner in which the lid body 100 shown in Fig. 2(a), the inner plate 200 shown in Fig. 3(c), the inner lid 300 shown in Fig. 5(a), and the container body 400 shown in Fig. 7(a) are stacked together.

[0056] As shown in FIG. 10, the shapes of the inner fitting portion 330 of the inner lid 300 and the container side fitting portion 430 of the container body 400 are the same, and they are fitted closely to each other without any gaps. In particular, the upper arc portion 350 of the inner fitting portion 330 is in close contact with the upper arc portion 450 of the container side fitting portion 430, and the lower arc portion 340 of the inner fitting portion 330 is in close contact with the lower arc portion 440 of the container side fitting portion 430, so that a double arc-shaped contact portion is formed at the fitting portion between the inner fitting portion 330 and the container side fitting portion 430. Furthermore, since the lower arc portion 340 and the upper arc portion 350 are arc-shaped, the contact area can be made larger. In addition, since the lower arc portion 340 and the upper arc portion 350 are arc-shaped, the fitting portion is unlikely to shift even when an external force is applied, and it is easy to maintain a state of close contact with each other. Therefore, the fitting portion between the inner fitting portion 330 and the container side fitting portion 430 has high sealing properties, and liquid leakage can be effectively prevented.

[0057] Here, a verification was carried out to verify whether liquid leakage can be effectively prevented by using the container body 400 in which the inner lid 300 is fitted inside and sealed while liquid is contained in the container portion 403. In order to verify the liquid leakage effect of the inner lid 300, the container body 400 in a state in which the inner plate 200 and the lid body 100 are removed is used. Specifically, the container body 400 containing liquid was tilted at about 45 degrees so that the liquid was soaked into the fitting portion between the inner fitting portion 330 and the container side fitting portion 430. This state was maintained for 30 minutes, 1 hour, 2 hours, and 3 hours, and it was confirmed that there was no liquid leakage in any of the times, and that high sealing properties could be maintained for a long time. On the other hand, the same verification was carried out with the conventional container of Patent Document 1. Specifically, with liquid contained in the lower stage side of the container body, the container body in which the reverse taper fitting portion of the inner lid was fitted inside the second reverse taper fitting portion of the container body was tilted at about 45 degrees so that the liquid was soaked into the fitting portion. This state was maintained for 30 minutes, 1 hour, 2 hours, and 3 hours, but liquid leakage occurred after 1 hour, resulting in lower sealing performance compared to the present invention. In the conventional container of Patent Document 1, the inverted tapered fitting portion is an inclined surface, so the fitting portion is likely to shift slightly up and down along the inclined surface, and it is believed that the weight of the liquid on the inner lid caused the fitting portion to shift slightly up and down along the inclined surface, resulting in liquid leakage.

[0058] Furthermore, as shown in FIG. 10, the shapes of the inner fitting portion 130 of the lid body 100 and the container side fitting portion 460 of the container body 400 match each other, and they are fitted closely to each other without any gaps. In particular, the upper arc portion 150 of the inner fitting portion 130 is in close contact with the upper arc portion 480 of the container side fitting portion 460, and the lower arc portion 140 of the inner fitting portion 130 is in close contact with the lower arc portion 470 of the container side fitting portion 460, so that a double arc-shaped contact portion is formed at the fitting portion between the inner fitting portion 130 and the container side fitting portion 460. Furthermore, since the lower arc portion 140 and the upper arc portion 150 are arc-shaped, the contact area can be made larger. In addition, since the lower arc portion 140 and the upper arc portion 150 are arc-shaped, the fitting portion is unlikely to shift even when an external force is applied, and it is easy to maintain a state of close contact with each other. Therefore, the fitting portion between the inner fitting portion 130 and the container side fitting portion 460 has high sealing properties, and liquid leakage can be effectively prevented.

[0059] Here, a verification was carried out to verify whether liquid leakage can be effectively prevented by using the container body 400 in which the lid body 100 was fitted and sealed with the liquid contained in the container portion 403. In order to verify the liquid leakage prevention effect of the lid body 100, the container body was examined with the inner plate 200 and the inner lid 300 removed. The container body 400 is used. Specifically, the container body 400 containing the liquid is tilted at about 45 degrees so that the liquid is immersed in the fitting portion between the inner fitting portion 130 and the container side fitting portion 460. This state was maintained for 30 minutes, 1 hour, 2 hours, and 3 hours, and it was confirmed that there was no liquid leakage in any of the times, and that high airtightness can be maintained for a long time. On the other hand, the same verification was performed with the conventional container of Patent Document 1. Specifically, with the liquid contained in the lower side of the container body, the container body in which the reverse taper fitting portion of the lid body is internally fitted into the first reverse taper fitting portion of the container body is tilted at about 45 degrees so that the liquid is immersed in the fitting portion. This state was maintained for 30 minutes, 1 hour, 2 hours, and 3 hours, but after 1 hour, liquid leakage occurred, and the result was that the airtightness was lower than that of the present invention. In the conventional container of Patent Document 1, the reverse taper fitting portion is an inclined surface, which makes it easy for the fitting point to shift slightly up and down along the inclined surface. It is therefore believed that the weight of the liquid on the inner lid caused the fitting point to shift slightly up and down along the inclined surface, resulting in liquid leakage.

[0060] 10, both the inner fitting portion 130 of the lid body 100 and the inner fitting portion 330 of the inner lid 300 have an upper arc portion and a lower arc portion, but the present invention is not limited thereto, and either the inner fitting portion 130 of the lid body 100 or the inner fitting portion 330 of the inner lid 300 may have an upper arc portion and a lower arc portion. If either the inner fitting portion 130 of the lid body 100 or the inner fitting portion 330 of the inner lid 300 has an upper arc portion and a lower arc portion, the container body 400 has high sealing properties and can effectively prevent liquid leakage, as described above.

[0061] In this way, in the container 500 of the present invention, when the internal fitting portion 130 of the lid body 100 includes the upper arc portion 150 and the lower arc portion 140 having an arc-shaped longitudinal section, and the shapes of the internal fitting portion 130 of the lid body 100 and the container side fitting portion 460 corresponding to the internal fitting portion 130 match each other, the fitting portions of the internal fitting portion 130 and the container side fitting portion 460 come into close contact with each other and have high sealing properties, and liquid leakage can be effectively prevented. In particular, since the lower arc portion 140 and the upper arc portion 150 are arc-shaped, the contact area can be made larger, and further, since the lower arc portion 140 and the upper arc portion 150 are arc-shaped, the fitting portions are unlikely to shift even when an external force is applied, so that they are easily kept in close contact with each other and have high sealing properties. Furthermore, when fitting the lid body 100 to the container body 400, even if the lid body 100 is pressed downward strongly to fit it, the upper arc portion 150 and the lower arc portion 140 are arc-shaped, so the fitting points are less likely to shift and the lid body 100 will not sink downward.

[0062] Similarly, in the container 500 of the present invention, when the inner fitting portion 330 of the inner lid 300 includes an upper arcuate portion 350 and a lower arcuate portion 340 having an arcuate longitudinal section, and the shapes of the inner fitting portion 330 of the inner lid 300 and the container side fitting portion 430 corresponding to the inner fitting portion 330 match each other, the fitting portions of the inner fitting portion 330 and the container side fitting portion 430 come into close contact with each other and have high sealing properties, thereby effectively preventing liquid leakage. In particular, since the lower arcuate portion 340 and the upper arcuate portion 350 are arcuate, the contact area can be made larger, and further, since the lower arcuate portion 340 and the upper arcuate portion 350 are arcuate, the fitting portions are unlikely to shift even when an external force is applied, so that they are easily kept in close contact with each other and have high sealing properties.

[0063] According to the container 500 of the present invention, as shown in FIG. 10, the upper container-side fitting portion 460 and the lower container-side fitting portion 430 of the container body 400 are vertically spaced from each other, and the lid body 100 internally fitted into the container-side fitting portion 460 and the inner lid 300 internally fitted into the container-side fitting portion 430 are also vertically spaced from each other. Therefore, even if the lid body 100 is pressed downward to fit the lid body 100 to the container body 400, the inner fitting portion 130 and other portions of the lid body 100 can be prevented from touching the inner fitting portion 330 of the inner lid 300 or the container-side fitting portion 430, and the fitting state between the inner lid 300 and the container-side fitting portion 430 is not affected. In other words, the fitting state of the inner lid 300 can be reliably maintained, so that the sealing property is high and liquid leakage can be effectively prevented. Similarly, when the lid body 100 is removed from the container body 400, the inner fitting portion 130 of the lid body 100 and other portions may come into contact with the inner fitting portion 330 of the inner lid 300 and the container side fitting portion 43. Since the inner lid 300 can be prevented from touching the inner lid 300, the fitted state of the inner lid 300 can be reliably maintained, and leakage of liquid can be effectively prevented.

[0064] According to the container 500 of the present invention, as shown in FIG. 2, the inner fitting portion 130 of the lid body 100 includes a flat portion 132 continuing to the upper end 152 of the upper arc portion 150, or a flat portion 131 continuing to the lower end 141 of the lower arc portion 140, and further, as shown in FIG. 7, the container side fitting portion 460 corresponding to the inner fitting portion 130 also includes a flat portion 461 having a shape matching the flat portion 131, or a flat portion 462 having a shape matching the flat portion 132. Therefore, the flat portions come into close contact with each other, so that the contact area between the inner fitting portion 130 of the lid body 100 and the container side fitting portion 460 can be made larger. Furthermore, since the flat portions come into contact with each other, the fitting portion between the inner fitting portion 130 of the lid body 100 and the container side fitting portion 460 is unlikely to shift even when an external force is applied. Therefore, the fitting portion between the inner fitting portion 130 and the container side fitting portion 460 has high sealing performance, and liquid leakage can be effectively prevented.

[0065] According to the container 500 of the present invention, as shown in FIG. 5, the inner fitting portion 330 of the inner lid 300 has a flat portion 332 continuing to the upper end 352 of the upper arc portion 350, or a flat portion 331 continuing to the lower end 341 of the lower arc portion 340, and further, as shown in FIG. 7, the container side fitting portion 430 corresponding to the inner fitting portion 330 also has a flat portion 431 having a shape matching the flat portion 331, or a flat portion 432 having a shape matching the flat portion 332. Therefore, the flat portions come into close contact with each other, so that the contact area between the inner fitting portion 330 of the inner lid 300 and the container side fitting portion 430 can be made larger. Furthermore, since the flat portions come into contact with each other, the fitting portion between the inner fitting portion 330 of the inner lid 300 and the container side fitting portion 430 is unlikely to shift even when an external force is applied. Therefore, the fitting portion between the inner fitting portion 330 and the container side fitting portion 430 has high sealing properties, making it possible to effectively prevent liquid leakage.

[0066] 10, in the container 500 of the present invention, the lid 100 is fitted inside the container body 400 to seal it, but the present invention is not limited to this. Instead of the lid 100, the container 500 may be sealed by heat-sealing a synthetic resin film to a part of the upper container-side fitting part 460 of the container body 400. By heat-sealing the film, the sealing property can be easily improved. Note that the film can be heat-sealed (thermally welded) to any part of the container-side fitting part 460, such as the flat part 462 of the container-side fitting part 460 or near the upper end 482 of the upper arc part 480.

[0067] 10, in the container 500 of the present invention, the inner lid 300 is fitted inside the container body 400, but the present invention is not limited to this. Instead of the inner lid 300, a synthetic resin film may be heat-sealed to a part of the container-side fitting part 430 at the lower stage of the container body 400. By heat-sealing the film, the airtightness can be easily improved. The film can be heat-sealed (thermally welded) to any part of the container-side fitting part 430, such as the flat part 432 of the container-side fitting part 430 or near the upper end 452 of the upper arc part 450.

[0068] As shown in FIG. 10, the inner fitting portion 130 of the lid 100 of the present invention is provided with a lower arc portion 140 closer to the internal space of the container 500. The length L2 (see FIG. 2) of the lower arc portion 140 is shorter than the length L1 of the upper arc portion 150, so the lower arc portion 140 is more rigid and less likely to deform than the upper arc portion 150. In this way, since the lower arc portion 140, which is more rigid and less likely to deform, is disposed closer to the internal space of the container 500, even if liquid or the like is about to leak from the internal space of the container 500 to the outside, the lower arc portion 140 is tightly attached to the container-side fitting portion 460, so that liquid leakage can be effectively prevented. Furthermore, even if steam is generated from the internal space of the container 500 when the container 500 is heated in a microwave oven, the lower arc portion 140, which is more rigid and less likely to deform, is tightly fitted to the container-side fitting portion 460. Therefore, the lid 100 will not come off forcefully due to water vapor.

[0069] 10, the inner fitting portion 330 of the inner lid 300 of the present invention is provided with a lower arc portion 340 closer to the storage portion 403 of the container body 400. Since the length L4 (see FIG. 5) of the lower arc portion 340 is shorter than the length L3 of the upper arc portion 350, the lower arc portion 340 is more rigid and less likely to deform than the upper arc portion 350. In this manner, since the lower arc portion 340, which is more rigid and less likely to deform, is disposed closer to the storage portion 403 of the container body 400, even if liquid or the like is about to leak from the internal space of the container 500 to the outside, the lower arc portion 340 is in strong contact with the container-side fitting portion 430, and thus the liquid leakage can be effectively prevented. Furthermore, even if water vapor is generated from the storage section 403 of the container body 400 when the container 500 is heated in a microwave oven, the lower arc section 340, which is highly rigid and difficult to deform, is tightly fitted into the container side fitting section 430, so that the inner lid 300 will not be forcefully detached by the water vapor.

[0070] Next, a method for removing the inner lid 300 of the container 500 of the present invention will be described with reference to Fig. 11. Fig. 11 shows the state in which the inner lid 300 is removed from the container 500 from which the lid body 100 and the inner plate 200 have been removed, with Fig. 11(a) being a plan view of this state and Fig. 11(b) being an EE end view of this state. Fig. 11 also assumes that a purchaser of the container 500 containing foodstuffs such as chilled noodles is about to eat the chilled noodles, and the purchaser first removes the lid body 100 from the container 500, and then temporarily removes the inner plate 200 containing foodstuffs such as condiments for the chilled noodles from the container 500.

[0071] 11, the purchaser pinches the inner surface 321 and the outer surface 322 of the handle 320 with finger F1 (e.g., thumb) and finger F2 (e.g., index finger), respectively, and pulls it upward. Then, the bottom wall 310 around the handle 320 is curved upward starting from hinge 313. Then, the engagement between the inner fitting portion 330 on the handle 320 side and the container side fitting portion 430 of the container body 400 is released. When the purchaser continues to pull the handle 320 upward, the engagement between the inner fitting portion 330' on the opposite side of the handle 320 and the container side fitting portion 430 also gradually releases, and the inner lid 300 can be completely removed. The purchaser then tilts the inner lid 300 towards the storage section 403 of the container body 400, and puts the noodles and other ingredients (not shown) stored on the bottom wall 310 of the inner lid 300 into the soup (not shown) in the storage section 403. Furthermore, by placing the ingredients such as condiments stored in the inner plate 200, which was once removed, on top of the noodles and soup in the storage section 403, the cold noodles are ready to be eaten. The purchaser can then use the container body 400 as a substitute for tableware and eat the cold noodles directly.

[0072] In this way, according to the container 500 of the present invention, since the handle 320 of the inner lid 300 protrudes upward from the bottom wall 310, a person can easily grasp and pull up the handle 320 with his / her fingers, and the inner lid 300 can be easily removed from the container body 400. In particular, since the handle 320 protrudes from the bottom wall 310, the force generated when the handle 320 is grasped and pulled up is directly transmitted to the bottom wall 310, and is further effectively transmitted from the bottom wall 310 to the inner fitting portion 330 provided on the outer edge of the bottom wall 310. Therefore, the engagement between the inner fitting portion 330 and the container side fitting portion 430 can be efficiently released, and as a result, the inner lid 300 can be easily removed from the container side fitting portion 430.

[0073] Furthermore, according to the container 500 of the present invention, the handle 320 of the inner lid 300 is provided at a position shifted from the center O of the inner lid 300 toward the outer edge 312, and the fitting strength of the inner fitting portion 330 located on the outside of the handle 320 is configured to be weaker than the fitting strength of the inner fitting portion 330' located on the opposite side to the outside of the handle 320. Therefore, when a person holds the handle 320 with their fingers and pulls it up, the fitting between the inner fitting portion 330 on the handle 320 side and the container side fitting portion 430 is easily released, making it easy to remove the inner lid 300.

[0074] Furthermore, according to the container 500 of the present invention, a hinge 313 is provided on the inside of the handle 320 of the inner lid 300. Therefore, when a person grasps the handle 320 with his / her fingers and pulls it up, the bottom wall 310 around the handle 320 is bent upward from the hinge 313, which makes it easier for the inner fitting portion 330 on the handle 320 side to disengage from the container side fitting portion 430, making it easier to remove the inner lid 300.

[0075] In addition, by providing the hinge 313 on the inside of the handle 320 of the inner lid 300, when the inner lid 300 is removed, the inner fitting portion 330 on the handle 320 side is first removed starting from the hinge 313. In other words, since the inner fitting portion 330 on the handle 320 side is removed first, the fitting around the entire periphery of the outer edge 312 of the inner lid 300 is not removed at once. For example, if the fitting around the entire periphery of the outer edge 312 of the inner lid 300 is removed at once, the inner lid 300 may jump up forcefully, and food such as noodles contained in the inner lid 300 may spill out of the container body 400. Therefore, in the container 500 of the present invention, the inner lid 300 is provided with the hinge 313, so that the inner lid 300 can be removed stepwise starting from the inner fitting portion 330 on the handle 320 side, and therefore the inner lid 300 can be prevented from jumping up forcefully.

[0076] 11(b), the inside of the handle 320 of the inner lid 300 is a space 323 surrounded by an inner surface 321 and an outer surface 322. Therefore, when the handle 320 is pinched with fingers, the handle 320 is elastically deformed so that the space 323 is crushed. When the space 323 of the handle 320 is elastically deformed so as to be crushed, the outer surface 322 of the handle 320 is curved inward, and the outer edge 312 and the inner fitting portion 330, which are continuous with the outer surface 322, are slightly bent inward. Therefore, the inner fitting portion 330 located on the handle 320 side is slightly bent inward, and the fitting with the container side fitting portion 430 is easily released, and the inner lid 300 can be easily removed. Furthermore, since the handle 320 extends in a long shape along the outer edge 312 of the inner lid 300, when the handle 320 is pinched with the fingers, the inner fitting portion 330 located on the handle 320 side can be bent inward over a wide range, making it even easier to remove the inner lid 300.

[0077] In addition, since the handle 320 is disposed inside the outer edge 312 of the inner lid 300, as shown in FIG. 11, there is a gap between the handle 320 and the side wall 420 of the container body 400 into which a finger F2 can be inserted. This makes it easy to hold the handle 320 with the finger F2, and makes it easy to remove the inner lid 300. Furthermore, as shown in FIG. 11(b), the handle 320 has a shape that widens toward the bottom wall 310. This makes the width of the handle 320 narrower toward the upper end of the handle 320, and therefore makes the gap between the handle 320 and the side wall 420 of the container body 400 larger, making it easy to hold the handle 320 with the finger F2, and making it even easier to remove the inner lid 300.

[0078] Next, a container 500A according to a first modified example of the present invention will be described with reference to Figs. 12 and 13. Fig. 12(a) is a plan view of the inner lid 300A of the container 500A, Fig. 12(b) is a side view of the inner lid 300A, Fig. 12(c) is an end view FF, Fig. 13(a) is a plan view of the inner lid 300A being removed from the container body 400A, and Fig. 13(b) is an end view GG. The container 500A according to the first modified example is the same as the container 500 except that the configuration of the inner lid 300A is different from the configuration of the inner lid 300 of the container 500 shown in Figs. 1 to 11, and other configurations are the same as the container 500, so detailed description of the same configurations will be omitted. Fig. 13 shows the container 500A with the inner plate 200A and the lid body 100A removed.

[0079] 12, the inner lid 300A is a shallow dish-shaped lid that opens upward, has a generally circular shape in a plan view, and includes a flat bottom wall 310A, a handle 320A that protrudes upward from the bottom wall 310A, and an inner fitting portion 330A provided on an outer edge 312A of the bottom wall 310A. The center side of the bottom wall 310A is formed with a recess 315A to accommodate noodles and the like. The inner fitting portion 330A is provided continuously or intermittently around the entire circumference of the inner lid 300A. A rotation stopper 314A protruding outward is provided on the outer edge 312A of the bottom wall 310A. A through hole 311A ​​penetrating the bottom wall 310A is formed in the center O of the inner lid 300A.

[0080] Handle 320A is formed in a thin sheet shape, and is a vertical wall extending in a long shape along outer edge 312A. As shown in FIG. 12(a), handle 320A, which is a vertical wall, extends along outer edge 312A, and is thus in the shape of an outwardly curved arc in plan view. Bottom wall 310A is provided with protrusion 316A on the inside of handle 320A. Foodstuffs such as noodles contained on bottom wall 310A come into contact with protrusion 316A, and are prevented from moving toward handle 320A.

[0081] The inner fitting portion 330A of the inner lid 300A has the same configuration as the inner fitting portion 330 of the inner lid 300 shown in Fig. 4, and a lower arc portion 340A having an arc-shaped vertical cross section and an upper arc portion 350A having an arc-shaped vertical cross section are provided on the lower and upper sides of the inner fitting portion 330A, respectively. Note that the vertical cross section refers to a cross section that appears when the inner fitting portion 330A is cut by a plane that intersects at a right angle with the opening surface of the inner lid 300A, as shown in Fig. 12(c).

[0082] 13(a) and (b), when the inner lid 300A is fitted into the lower container side fitting portion 430A of the container body 400A, the handle 320A is spaced from the side wall 420A of the container body 400A, and a gap XA is generated between the handle 320A and the side wall 420A. When removing the inner lid 300A, a finger F2 is inserted into the gap XA, and the handle 320A is grasped and pulled up by fingers F1 and F2. A rotation stopper 314A is stored in the storage portion 421A of the container body 400A so that the inner lid 300A does not rotate in the container body 400A.

[0083] In the inner lid 300A shown in FIG. 12, the handle 320A is a vertical wall extending in a long shape along the outer edge 312A, but is not limited thereto. As will be described later with reference to FIG. 14, the handle 320A may be in the form of a short knob, and any shape can be adopted as long as it is in a sheet shape. Although not shown, when the inner plate 200A is placed above the inner lid 300A, the tip of the handle 320A protrudes from the recess 250A of the inner plate 200A. By having the handle 320A protrude from the recess 250A, a rotation prevention effect can be obtained so that the inner plate 200A does not rotate inside the container body 400A, and further, since the food such as noodles contained on the inner lid 300A does not touch the tip side of the handle 320A, the user who holds the handle 320A does not feel uncomfortable and is hygienic.

[0084] In this way, the inner lid 300A of the container 500A according to the first modified example of the present invention has a sheet-like handle 320A protruding from the outer edge 312A side of the inner lid 300, so that by pinching and pulling up the handle 320A with fingers, the inner fitting portion 330A provided on the outer edge 312A can be easily removed from the container side fitting portion 430A, and the inner lid 300A can be easily removed. Furthermore, since the handle 320A is sheet-like, it does not narrow the food storage space on the bottom wall 310A, and a large amount of food can be efficiently stored. Also, as shown in FIG. 13, when the inner lid 300A is internally fitted into the container side fitting portion 430A on the lower side of the container body 400A, the handle 320A is separated from the side wall 420A of the container body 400A to form a gap XA, so that a finger F2 can be inserted into this gap XA, and the handle 320A can be easily pinched up.

[0085] In addition, in the inner lid 300A of the container 500A according to the first modified example of the present invention, the handle 320A is a vertical wall portion that extends in a long shape along the outer edge 312A of the inner lid 300A, so that the area that can be held by a person's fingers is increased, and the handle 320A can be picked up more easily. come.

[0086] Next, a container 500B according to a second modification of the present invention will be described with reference to Figs. 14 and 15. Fig. 14(a) is a plan view of the inner lid 300B of the container 500B, Fig. 14(b) is a side view of the inner lid 300B, Fig. 14(c) is an HH end view, Fig. 15(a) is a plan view of the inner lid 300B being removed from the container body 400B, and Fig. 15(b) is an II end view. The container 500B according to the second modification is the same as the container 500 except that the configuration of the inner lid 300B is different from the configuration of the inner lid 300 of the container 500 shown in Figs. 1 to 11, and other configurations are the same as the container 500, so detailed description of the same configurations will be omitted. Fig. 15 shows the container 500B with the inner plate 200B and the lid body 100B removed.

[0087] As shown in FIG. 14, the inner lid 300B is a shallow dish type that opens upward, has a generally circular shape in a plan view, and includes a flat bottom wall 310B, a handle 320B that protrudes outward from an outer edge 312B of the bottom wall 310B, and an inner fitting portion 330B provided on the outer edge 312B. The bottom wall 310B has a recess 315B at its center for storing noodles and the like. The inner fitting portion 330B is provided continuously or intermittently around the entire circumference of the inner lid 300B in the circumferential direction. The outer edge 312B of the bottom wall 310B is provided with a rotation stopper 314B that protrudes outward. Furthermore, a through hole 311B that penetrates the bottom wall 310B is formed at the center O of the inner lid 300B.

[0088] Handle 320B is formed in a thin sheet shape and extends outward from outer edge 312B. Handle 320B has recess 327B in the center, and bottom surface 324B of recess 327B bulges outward. Handle 320B is flexible and can bend around bending portion 325B. Bottom wall 310B has protrusion 316B on the inside of handle 320B. Foodstuffs such as noodles placed on bottom wall 310B come into contact with protrusion 316B and are prevented from moving toward handle 320B.

[0089] The inner fitting portion 330B of the inner lid 300B has the same configuration as the inner fitting portion 330 of the inner lid 300 shown in Fig. 4, and a lower arc portion 340B having an arc-shaped vertical cross section and an upper arc portion 350B having an arc-shaped vertical cross section are provided on the lower and upper sides of the inner fitting portion 330B, respectively. Note that the vertical cross section refers to a cross section that appears when the inner fitting portion 330B is cut by a plane that intersects at a right angle with the opening surface of the inner lid 300B, as shown in Fig. 14(c).

[0090] 15(a) and (b), when the inner lid 300B is fitted into the lower container-side fitting portion 430B of the container body 400B, the bottom surface 324B of the handle 320B abuts against the side wall 420B, and the handle 320B is raised upward. Since the bottom surface 324B, which bulges outward, abuts against the side wall 420B, a gap XB is generated between the tip 326B of the handle 320B and the side wall 420B. Since the handle 320B is flexible, it can be deformed to rise upward without any difficulty.

[0091] When removing the inner lid 300B, the finger F2 is inserted into the gap XB, and the handle 320B is pinched and pulled up by the fingers F1 and F2. A rotation stopper 314B is stored in the storage section 421B so that the inner lid 300B does not rotate in the container body 400B. In the inner lid 300B shown in FIG. 14, the handle 320B has a recess 327B so that the handle can abut against the side wall 420B of the container body 400B. However, the shape of the handle 320B is not limited to this, and as long as a part of the handle 320B abuts against the side wall 420B and a gap XB is formed between the handle 320B and the side wall 420B, the shape of the handle 320B can be any shape, such as a protrusion protruding toward the side wall 420B. Although not shown, in a state where the inner lid 300B is fitted into the container side fitting portion 430B on the lower side of the container body 400B, the inner lid When inner plate 200B is placed above inner lid 300B, the tip of handle 320B protrudes from recess 250B of inner plate 200B. By having handle 320B protrude from recess 250B, an anti-rotation effect is obtained so that inner plate 200B does not rotate inside container body 400B, and further, since food such as noodles contained on inner lid 300B does not come into contact with the tip of handle 320B, it is hygienic and does not cause discomfort to a user who holds handle 320B.

[0092] In this way, the inner lid 300B of the container 500B according to the second modified example of the present invention has a sheet-like handle 320B protruding from the outer edge 312B side of the inner lid 300B, so that by pinching and pulling up the handle 320B with fingers, the inner fitting portion 330B provided on the outer edge 312B can be easily removed from the container side fitting portion 430B, and the inner lid 300B can be easily removed. Furthermore, since the handle 320B is sheet-like, it does not narrow the food storage space on the bottom wall 310B, and a large amount of food can be efficiently stored. Also, as shown in FIG. 15, when the inner lid 300B is internally fitted into the container side fitting portion 430B on the lower side of the container body 400B, the handle 320B is separated from the side wall 420B of the container body 400B and has a gap XB, so that a finger F2 can be inserted into this gap XB, and the handle 320B can be easily pinched up.

[0093] In addition, in the inner lid 300B of the container 500B according to the second modification of the present invention, the handle 320B is flexible, so that when the inner lid 300B is fitted into the lower container fitting portion 430B of the container body 400B, a part of the handle 320B abuts against the side wall 420B, and the handle 320B stands up. Then, the handle 320B can be easily picked up by inserting the finger F2 into the gap XB from above.

[0094] In particular, as shown in Fig. 14, when the inner lid 300B is not fitted inside the container body 400B, the handle 320B is in a state of being tilted outward so as to be approximately horizontal with the plane of the bottom wall 310B, so that the height of the inner lid 300B can be made low and the storage space for the inner lid 300B does not become bulky. Furthermore, when the inner lid 300B is fitted inside the container side fitting portion 430A on the lower side of the container body 400A, the flexible handle 320B rises upward naturally, so that the handle 320B can be easily picked up and lifted.

[0095] In addition, in the inner lid 300B of the container 500B according to the second modification of the present invention, the handle 320B has a recess 327B, so that when the handle 320B is picked up, the finger F1 fits inside the recess 327B, making it easy to pick up the handle 320B, as shown in Fig. 15(b). Furthermore, the bottom surface 324B of the recess 327B abuts against the side wall 420B, and a gap XB is formed between the handle 320B and the side wall 420B, so that the finger F2 can be inserted into the gap XB to easily pick up the handle 320B.
