Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the present specification, "upper" means an upward direction in the vertical direction when the container is placed on a horizontal plane with the opening surface of the container body facing up, and "downward" means. In the vertical direction, it is a downward direction, "horizontal" is a horizontal direction, and "vertical" is a direction perpendicular to "horizontal" in a horizontal plane.

First, FIGS. 1 and 2 show the lid 100 of the container 500 of the present invention. 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 end view of AA of FIG. 1 (a), and FIG. 2 (b). ) Is an enlarged end view of the portion surrounded by the dotted line in FIG. 2 (a).

As shown in FIGS. 1 and 2, the lid 100 has a shallow dish shape that opens downward, has a substantially circular shape in a plan view, and is below the flat top plate 110 and the edge 111 of the top plate 110. A side wall 120 continuous toward the side and an inner fitting portion 130 provided at the lower end of the side wall 120 are provided. A protrusion 112 that protrudes upward from the top plate 110 is formed on the edge 111 of the top plate 110, and the bottom wall of the container body, which will be described later, can be arranged inside the protrusion 112. Therefore, when the containers 500 are stacked, the bottom wall of the container body of the stacked containers 500 is surrounded by the protrusion 112 of the lid 100 of the lower container 500, so that the upper container 500 is displaced. It does not fall off and can be stacked stably. The side wall 120 and the inner fitting portion 130 are provided continuously or intermittently over the entire circumference of the lid 100 in the circumferential direction.

Further, as shown in FIG. 2B, a lower arc portion 140 having an arcuate vertical cross section and an upper arcuate portion 150 having an arcuate vertical cross section are provided on the lower side and the upper side of the inner fitting portion 130, respectively. It is provided. The lower end 141 of the lower arc portion 140 is provided with a flat portion 131 extending laterally from the lower end 141, and the flat portion 131 is continuous with the lower end 121 of the side wall 120. Further, the upper end 152 of the upper arc portion 150 is also provided with a flat portion 132 extending laterally from the upper end 152. As shown in FIG. 2, the vertical cross section is a cross section that appears when the inner fitting portion 130 is cut by a plane that intersects the opening surface of the lid 100 at a right angle. Further, the inner fitting portion 130 includes both the flat portion 131 and the flat portion 132, but is not limited to this, and may include only one of the flat portion 131 or the flat portion 132.

Further, as shown in FIG. 2B, 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. ing. The upper arc portion 150 is formed so as to draw an arc larger than that of 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.

Further, the central angle θ1 of the upper arc portion 150 is larger than 90 degrees (that is, 90 ° <θ1). By making the central angle θ1 of the upper arc portion 150 larger than 90 degrees in this way, the fitting with the container-side fitting portion described later becomes stronger. On the other hand, the central angle θ2 of the lower arc portion 140 is 90 degrees or less (that is, θ2 ≦ 90 °). By setting the central angle θ2 of the lower arc portion 140 to 90 degrees or less in this way, the so-called undercut portion is reduced when the lid body 100 is sheet-molded, so that the lid body 100 can easily come off from the mold. It becomes.

Further, the lower arc portion 140 and the upper arc portion 150 are connected by an intermediate portion 133 in a vertically separated state. Specifically, since 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, the lower arc portion 140 and the upper arc portion 150 are continuous. , It is in a state of being separated vertically via the intermediate portion 133. In this way, the lower arc portion 140 and the upper arc portion 150 are not directly continuous and are separated from each other via the intermediate portion 133, so that the sealing property of the inner fitting portion 130 can be more reliably maintained. Can be done. For example, when an external force is applied to the edge of the lid 100, the upper arc portion 150 located on the edge side may be deformed, but the lower arc portion 140 is separated from the upper arc portion 150 by the intermediate portion 133. Because it is, it is hard to deform. Therefore, even if an external force is carelessly applied to the edge portion of the lid body 100, the sealing property of the inner fitting portion 130 as a whole is ensured.

Further, a recess 134 is provided between the lower arc portion 140 and the upper arc portion 150 so as to be enclosed inward from the arc surface of the lower arc portion 140 and the upper arc portion 150. Therefore, as will be described later, the area in which the inner fitting portion 130 is in close contact with the container-side fitting portion, which will be described later, is increased, and the sealing property is further improved. A concave portion 134 is provided between the lower arc portion 140 and the upper arc portion 150, but the present invention is not limited to this, and a convex portion may be provided so as to increase the contact area.

The length L1 of the upper arc portion 150 is longer than the length L2 of the lower arc portion 140, but the length L1 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 length, 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 portion of the lid 100, the upper arc portion 150 located on the edge portion side can be formed. Since the total length is long, it can be firmly fitted to the container body side, so that it is possible to effectively prevent the lid 100 from being inadvertently removed. The lid 100 shown in FIGS. 1 and 2 has a configuration in which the inner fitting portion 130 includes a lower arc portion 140 and an upper arc portion 150, but is not limited to this, and the inner fitting portion of the lid 100 is not limited to this. If the 130 can be internally fitted to the lower container-side fitting portion of the container body 400, another configuration such as a configuration including a reverse-tapered inner fitting portion may be adopted.

Next, FIG. 3 shows the inner plate 200 of the container 500 of the present invention. 3A is a plan view of the middle plate 200, FIG. 3B is a side view of the middle plate 200, and FIG. 3C is an end view of the BB.

As shown in FIG. 3, the middle plate 200 is a shallow plate type that opens upward, has a substantially circular shape in a plan view, and rises upward from the flat bottom wall 210 and the edge of the bottom wall 210. A continuous side wall 220 and a partition wall 221 for individually accommodating foodstuffs and the like are provided. Further, on the outside of the side wall 220, a skirt portion 230 extending downward from the upper end of the side wall 220 is provided, and a flange portion 240 extending substantially horizontally from the lower end of the skirt portion 230 is provided. The side wall 220, the skirt portion 230, and the flange portion 240 are provided continuously or intermittently over the entire circumference of the middle plate 200 in the circumferential direction.

Further, as shown in FIG. 3, the middle plate 200 is provided with a recess 250 recessed inward from the outer edge of the middle plate 200. The recess 250 has a size that allows the handle of the inner lid, which will be described later, to be arranged. In addition, foods such as condiments and vegetables can be stored in the space partitioned by the partition wall 221 on the bottom wall 210, and the stored foods have a fine uneven shape on the bottom wall 210 so as not to shift. The non-slip 211 is formed.

Next, FIGS. 4 and 5 show the inner lid 300 of the container 500 of the present invention. 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), and FIG. 5 (b). ) Is an enlarged end view of the portion surrounded by the dotted line on the right side in FIG. 5 (a), and FIG. 5 (c) is an enlarged end view of the portion surrounded by the alternate long and short dash line on the left side in FIG. 5 (a).

As shown in FIGS. 4 and 5, the inner lid 300 has a shallow dish shape that opens upward, has a substantially circular shape in a plan view, and has a flat bottom wall 310 and a projecting upward from the bottom wall 310. The handle 320 and the inner fitting portion 330 provided on the outer edge 312 of the bottom wall 310 are provided. In order to accommodate noodles and the like in the bottom wall 310, the central side of the bottom wall 310 is a recess 315. The inner fitting portion 330 is provided continuously or intermittently over the entire circumference of the inner lid 300 in the circumferential direction. Further, the outer edge 312 of the bottom wall 310 is provided with a detent 314 protruding outward.

Further, a through hole 311 penetrating the bottom wall 310 is formed in the center O of the inner lid 300. As will be described later, since the inner lid 300 is covered with a liquid such as soup on the lower side of the container body, the through hole 311 is used to let air escape. Further, the handle 320 has a substantially triangular pyramid shape in the side view, and the handle 320 has a thin wall shape so that it can be easily picked up by a human finger. Further, the inner surface 321 and the outer surface 322 of the handle 320 are curved surfaces so that they can be easily picked up by the fingertips. Further, the handle 320 is arranged at a position deviated from the center O of the inner lid 300 toward the outer edge 312 side of the inner lid 300. A hinge (bent portion) 313 extending linearly is provided inside the handle 320. The hinge 313 is formed by a groove linearly provided in the bottom wall 310, and by lifting the handle 320, the bottom wall 310 around the handle 320 is bent upward with the hinge 313 as a starting point. Can be done. The hinge 313 is in the form of a linear groove, but the present invention is not limited to this, and other as long as the bottom wall 310 around the handle 320 can be bent upward from the hinge 313 as a starting point. It may be in the form.

Further, the inner fitting portion 330 of the inner lid 300 is basically the same as the configuration of the inner fitting portion 130 of the lid body 100, and each of the lower side and the upper side of the inner fitting portion 330 has a vertical cross section. A lower arc portion 340 having an arc shape and an upper arc portion 350 having an arc shape in the vertical cross section are provided. The lower end 341 of the lower arc portion 340 is provided with a flat portion 331 extending laterally from the lower end 341, and the flat portion 331 is continuous with the bottom wall 310. Further, the upper end 352 of the upper arc portion 350 is also provided with a flat portion 332 extending laterally from the upper end 352. As shown in FIG. 5, 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. Further, the inner fitting portion 330 includes both the flat portion 331 and the flat portion 332, but is not limited to this, and may include only one of the flat portion 331 or the flat portion 332.

Further, as shown in FIG. 5, the upper arc portion 350 has an arc shape with a radius R3 and a central angle θ3, and similarly, the lower arc portion 340 has an arc shape with a radius R4 and a central angle θ4. The upper arc portion 350 is formed so as to draw an arc larger than that of the lower arc portion 340, and the length L3 of the upper arc portion 350 is longer than the length L4 of the lower arc portion 340.

Further, the central angle θ3 of the upper arc portion 350 is larger than 90 degrees (that is, 90 ° <θ3). By making the central angle θ3 of the upper arc portion 350 larger than 90 degrees in this way, the fitting with the container-side fitting portion described later becomes stronger. On the other hand, the central angle θ4 of the lower arc portion 340 is 90 degrees or less (that is, θ4 ≦ 90 °). By setting the central angle θ4 of the lower arc portion 340 to 90 degrees or less, the so-called undercut portion is reduced when the inner lid 300 is sheet-molded, so that the inner lid 300 can be easily removed from the mold.

Further, the lower arc portion 340 and the upper arc portion 350 are connected by an intermediate portion 333 in a vertically separated state. Specifically, since 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, the lower arc portion 340 and the upper arc portion 350 are continuous. , It is in a state of being separated vertically via the intermediate portion 333. In this way, the lower arc portion 340 and the upper arc portion 350 are not directly continuous and are separated from each other via the intermediate portion 333, so that the sealing property of the inner fitting portion 330 can be more reliably maintained. Can be done. 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 separated from the upper arc portion 350 by the intermediate portion 333. Because it is, it is hard to deform. Therefore, even if an external force is carelessly applied to the outer edge of the inner lid 300, the sealing property of the inner fitting portion 330 as a whole is ensured.

Further, a recess 334 is provided between the lower arc portion 340 and the upper arc portion 350 so as to be enclosed inward from the arc surface of the lower arc portion 340 and the upper arc portion 350. Therefore, as will be described later, the area in which the inner fitting portion 330 is in close contact with the container-side fitting portion, which will be described later, is increased, and the sealing property is further improved. A concave portion 334 is provided between the lower arc portion 340 and the upper arc portion 350, but the present invention is not limited to this, and a convex portion may be provided so as to increase the contact area.

The length L3 of the upper arc portion 350 is longer than the length L4 of the lower arc portion 340, but the length L3 of the upper arc portion 350 and the length L4 of the lower arc portion 340 are not limited to this. 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.

Further, the inner fitting portion 330 is provided on the entire circumference of the outer edge 312 of the inner lid 300, but the fitting strength of the inner fitting portion 330 located outside the handle 320 of the inner lid 300 is the handle 320. It is configured to be weaker than the fitting strength of the inner fitting portion 330'located on the side opposite to the outside of the lid. 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 each configuration of the inner fitting portion 330. "'" Is added to the code of the element to represent it, and detailed description of the same configuration is omitted.

As shown in FIG. 5 (b), in the inner fitting portion 330 located on the handle 320 side, the central angle of the upper arc portion 350 is θ3, and as shown in FIG. 5 (c), the handle In the inner fitting portion 330'located on the opposite side of the 320, the central angle of the upper arc portion 350'is θ3'. The central angle θ3 of the upper arc portion 350 of the inner fitting portion 330 located on the handle 320 side is the central angle θ3 of the upper arc portion 350'of the inner fitting portion 330'located on the opposite side of the handle 320. It is slightly smaller than'. Therefore, when the inner fitting portion 330 of the inner lid 300 is internally fitted to the container-side fitting portion of the container body, which will be described later, the upper arc portion 350 having a small central angle θ3 becomes the upper arc portion 350'on the opposite side. Compared to the above, the fitting portion on the container side is shallowly fitted. Therefore, the fitting strength of the inner fitting portion 330 located on the outside of the handle 320 of the inner lid 300 is weaker than the fitting strength of the inner fitting portion 330'located on the side opposite to the outside of the handle 320. It is.

In the inner lid 300 shown in FIG. 5, the central angle θ3 of the upper arc portion 350 of the inner fitting portion 330 located on the handle 320 side is set to the upper arc portion 350 of the inner fitting portion 330'located on the opposite side. The undercut amount of the upper arc portion 350 of the inner fitting portion 330 located on the handle 320 side is set to be smaller than the central angle θ3 of', and the upper arc portion of the inner fitting portion 330'located on the opposite side. Although it is smaller than the undercut amount of 350', the fitting strength of the inner fitting portion 330 located outside the handle 320 of the inner lid 300 is opposite to that of the outside of the handle 320. If it can be configured to be weaker than the fitting strength of the inner fitting portion 330'located on the side, for example, the shape of the upper arc portion 350 located on the handle 320 side may be changed to change the shape of the upper arc portion 350 and the container. An arbitrary configuration may be appropriately adopted, such as making the fitting area with the side fitting portion smaller than the fitting area between the upper arc portion 350'located on the opposite side of the handle 320 and the container side fitting portion. Can be done.

The inner lid 300 shown in FIGS. 4 and 5 has a configuration in which the inner fitting portion 330 includes a lower arc portion 340 and an upper arc portion 350, but is not limited to this, and the inner fitting portion of the inner lid 300 is not limited to this. If the 330 can be internally fitted to the lower container-side fitting portion of the container body 400, another configuration such as a configuration including a reverse-tapered inner fitting portion may be adopted.

Next, FIGS. 6 and 7 show the container body 400 of the container 500 of the present invention. 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 portion surrounded by the dotted line in FIG. 7A.

As shown in FIGS. 6 and 7, the container main body 400 is a deep dish type that opens upward, has a substantially circular shape in a plan view, and is formed from a flat bottom wall 410 and an edge portion 411 of the bottom wall 410. A side wall 420 that is continuous so as to stand up upward, a container-side fitting portion 430 provided inside the lower side of the side wall 420, and a container-side fitting portion 460 provided inside the upper side of the side wall 420. Be prepared. A storage portion 403 surrounded by a bottom wall 410 and a side wall 420 is formed on the lower side of the container body 400 so that food such as liquid can be stored. The side wall 420, the container-side fitting portion 430 on the lower stage side, and the container-side fitting portion 460 on the upper end side are provided continuously or intermittently over the entire circumference in the circumferential direction of the container body 400. Further, the outer edge 401 of the container body 400 is provided with a knob portion 402 protruding outward.

Further, the inner lid 300 can be internally fitted to the container-side fitting portion 430 on the lower stage side of the container body 400, and the shape of the container-side fitting portion 430 and the inner fitting portion 330 of the inner lid 300. The shapes of are the same. Specifically, each of the lower side and the upper side of the container-side fitting portion 430 is provided with a lower arc portion 440 having an arc-shaped vertical cross section and an upper arc portion 450 having an arc-shaped vertical cross section. The lower arc portion 440 has the same shape as the lower arc portion 340 so that it can be brought into close contact with the lower arc portion 340 of the inner fitting portion 330 of the inner lid 300. Further, the upper arc portion 450 has the same shape as the upper arc portion 350 so that it can be fitted in close contact with the upper arc portion 350 of the inner fitting portion 330 of the inner lid 300.

It is configured so that it can be brought into close contact with the flat portion 132 of the inner fitting portion 130 of the body 100.

Further, as shown in FIG. 6A, a part of the side wall 420 between the lower container-side fitting portion 430 and the upper container-side fitting portion 460 is outward as if the side wall 420 was cut out. A recessed storage portion 421 is provided. The storage portion 421 is continuous with the flat portion 432 of the container-side fitting portion 430, and can accommodate the detent 314 of the inner lid 300 internally fitted in the container-side fitting portion 430.

The lid 100, the inner plate 200, the inner lid 300, and the container body 400 according to the present embodiment are sheet-molded (for example, using a sheet-like material having a thickness of about 0.1 mm to 1.0 mm). , Vacuum forming, pressure forming, hot plate forming). For example, the materials of the lid 100, the inner plate 200, and the container body 400 include polystyrene, polypropylene, polystyrene, A-PET, polylactic acid, and the like. As the material of the inner lid 300, polystyrene, polypropylene, polystyrene, A-PET, polylactic acid, foamed products of these, or a mixture of talc can be used. The lid body 100, the inner plate 200, the inner lid 300, and the container body 400 are substantially circular in a plan view, but other shapes such as a polygon in a plan view can be appropriately changed.

Next, a method of containing food in the container 500 of the present invention will be described with reference to FIGS. 8 and 9. 8 is a side view showing the container 500 of the present invention in an exploded manner, FIG. 9A is a plan view of the container body 400 with the inner lid 300 internally fitted, and FIG. 9B is a plan view. It is a top view of the state which covered the inner plate 200 from the top of the inner lid 300 with the inner lid 300 internally fitted to the container main body 400.

Here, for example, when storing foodstuffs such as cold noodles in the container 500, as shown in FIG. 8, first, a liquid such as cold noodle soup is filled in the storage portion 403 on the lower side of the container body 400. To accommodate. The liquid is stored below the container-side fitting portion 430 with a certain margin so as not to exceed the container-side fitting portion 430 of the container body 400. In that state, in order to seal the accommodating portion 403, the inner lid 300 is internally fitted to the container-side fitting portion 430 from above the accommodating portion 403. As shown in FIG. 9A, when the inner lid 300 is internally fitted to the container body 400, the inner lid 300 is stored so that the detent 314 of the inner lid 300 is housed in the storage portion 421 of the container body 400. Adjust the position of. By storing the detent 314 in the storage portion 421, the detent effect can be obtained so that the inner lid 300 does not rotate in the container body 400.

Next, ingredients such as cold noodles are placed and stored on the bottom wall 310 of the inner lid 300. Then, the inner plate 200 is covered so as to cover the inner lid 300. Specifically, as shown in FIG. 9B, the flange portion 240 of the middle plate 200 is placed on the flat portion 461 of the upper stage of the container body 400, and the middle plate 200 is arranged in the container body 400. Further, 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 projecting the handle 320 from the recess 250, it is possible to obtain the effect of preventing the inner plate 200 from rotating in the container body 400. Further, since the tip of the handle 320 protrudes from the recess 250, food such as noodles housed on the inner lid 300 does not touch the tip side of the handle 320. Therefore, since food or the like does not adhere to the tip side of the handle 320, the user who picks the handle 320 does not feel uncomfortable and is hygienic.

Next, ingredients such as condiments of cold noodles are placed and stored on the bottom wall 210 partitioned by the partition wall 221 of the middle plate 200. Then, the lid 100 is internally fitted to the container-side fitting portion 460 of the container body 400 so as to cover the inner plate 200, and is sealed. The sealed container 500 in which each ingredient of the cold noodles is individually stored is displayed and sold at a store or the like.

Then, the state in which the container 500 is sealed will be described with reference to FIG. FIG. 10 is a vertical end view of the container 500 in a sealed state. The vertical end view of the container 500 of FIG. 10 shows the lid 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 FIG. It is an enlarged end view showing both ends of the container 500 in a state where the container body 400 shown in (a) is overlapped.

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 match each other, and they are closely fitted to each other without any gap. 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 the lower arc portion 440 of the container side fitting portion 430. Since it is in close contact with the inner fitting portion 330, an arc-shaped close contact portion is formed twice at the fitting portion between the inner fitting portion 330 and the container side fitting portion 430. Further, since the lower arc portion 340 and the upper arc portion 350 have an arc shape, the contact area can be further increased. Further, since the lower arc portion 340 and the upper arc portion 350 have an arc shape, the fitting portion is less likely to shift even when an external force is applied, and it is easy to maintain a state of being in close contact with each other. Therefore, the fitting portion between the inner fitting portion 330 and the container-side fitting portion 430 has a high sealing property, and liquid leakage can be effectively prevented.

Here, it was verified whether or not the liquid leakage could be effectively prevented by using the container main body 400 in which the inner lid 300 was internally fitted and sealed with the liquid stored in the storage portion 403. In order to verify the liquid leakage effect of the inner lid 300, the inner plate 200 and the lid 100 use the container body 400 in a removed state. Specifically, the container body 400 containing the liquid was tilted by about 45 degrees so that the liquid was immersed in the fitting portion between the inner fitting portion 330 and the container side fitting portion 430. The state was maintained for 30 minutes, 1 hour, 2 hours, and 3 hours, but it was confirmed that there was no liquid leakage at any time and high airtightness could be maintained for a long time. On the other hand, the same verification was performed on the conventional container of Patent Document 1. Specifically, the container body in which the reverse taper fitting portion of the inner lid is internally fitted to the second reverse taper fitting portion of the container body with the liquid stored in the lower stage side of the container body is approximately 45 degrees. Tilt to allow the liquid to immerse in the mating area. This state was maintained for 30 minutes, 1 hour, 2 hours, and 3 hours, but after 1 hour, liquid leakage occurred, resulting in lower airtightness as compared with the present invention. In the conventional container of Patent Document 1, since the reverse taper fitting portion is an inclined surface, the fitting portion is easily displaced up and down along the inclined surface, so that the weight of the liquid applied to the inner lid is increased. It is probable that the fitting portion was slightly displaced up and down along the inclined surface, causing liquid leakage.

Further, 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 are in agreement with each other, and are closely fitted to each other without any gap. 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 the lower arc portion 470 of the container side fitting portion 460. Since it is in close contact with the inner fitting portion 130, an arc-shaped close contact portion is formed twice at the fitting portion between the inner fitting portion 130 and the container side fitting portion 460. Further, since the lower arc portion 140 and the upper arc portion 150 have an arc shape, the contact area can be further increased. Further, since the lower arc portion 140 and the upper arc portion 150 have an arc shape, the fitting portion is less likely to shift even when an external force is applied, and it is easy to maintain a state of being in close contact with each other. Therefore, the fitting portion between the inner fitting portion 130 and the container-side fitting portion 460 has a high sealing property, and liquid leakage can be effectively prevented.

Here, it was verified whether or not the liquid leakage could be effectively prevented by using the container body 400 in which the lid 100 was internally fitted and sealed with the liquid stored in the storage portion 403. In order to verify the liquid leakage effect of the lid 100, the inner plate 200 and the inner lid 300 use the container body 400 in a removed state. Specifically, the container body 400 containing the liquid was tilted by about 45 degrees so that the liquid was immersed in the fitting portion between the inner fitting portion 130 and the container side fitting portion 460. The state was maintained for 30 minutes, 1 hour, 2 hours, and 3 hours, but it was confirmed that there was no liquid leakage at any time and high airtightness could be maintained for a long time. On the other hand, the same verification was performed on the conventional container of Patent Document 1. Specifically, the container body in which the reverse taper fitting portion of the lid is internally fitted to the first reverse taper fitting portion of the container body with the liquid stored in the lower stage side of the container body is approximately 45 degrees. Tilt to allow the liquid to immerse in the mating area. This state was maintained for 30 minutes, 1 hour, 2 hours, and 3 hours, but after 1 hour, liquid leakage occurred, resulting in lower airtightness as compared with the present invention. In the conventional container of Patent Document 1, since the reverse taper fitting portion is an inclined surface, the fitting portion is easily displaced up and down along the inclined surface, so that the weight of the liquid applied to the inner lid is increased. It is probable that the fitting portion was slightly displaced up and down along the inclined surface, causing liquid leakage.

In the container 500 shown in FIG. 10, both the inner fitting portion 130 of the lid 100 and the inner fitting portion 330 of the inner lid 300 are provided with an upper arc portion and a lower arc portion, but the present invention is limited to this. Instead, one of the inner fitting portion 130 of the lid 100 or the inner fitting portion 330 of the inner lid 300 may include an upper arc portion and a lower arc portion. If either the inner fitting portion 130 of the lid 100 or the inner fitting portion 330 of the inner lid 300 includes an upper arc portion and a lower arc portion, the container body 400 has a sealing property as described above. Is high, and liquid leakage can be effectively prevented.

As described above, in the container 500 of the present invention, the inner fitting portion 130 of the lid body 100 includes the upper arc portion 150 and the lower arc portion 140 having an arcuate vertical cross section, and the inner fitting portion 130 of the lid body 100. When the shapes of the container-side fitting portion 460 corresponding to the inner fitting portion 130 match each other, the fitting portions of the inner fitting portion 130 and the container-side fitting portion 460 are in close contact with each other. It has a high sealing property and can effectively prevent liquid leakage. In particular, since the lower arc portion 140 and the upper arc portion 150 have an arc shape, the contact area can be made larger, and further, since the lower arc portion 140 and the upper arc portion 150 have an arc shape, the fitting portion can be fitted even if an external force is applied. Since it is hard to shift, it is easy to maintain a state of close contact with each other and the sealing property is high. Further, when the lid body 100 is fitted to the container body 400, even if the lid body 100 is strongly pushed downward to be fitted, the upper arc portion 150 and the lower arc portion 140 have an arc shape, so that the fitting portion Is hard to shift, and the lid 100 does not sink downward.

Similarly, in the container 500 of the present invention, the inner fitting portion 330 of the inner lid 300 includes an upper arc portion 350 and a lower arc portion 340 having an arcuate vertical cross section, and the inner fitting portion 330 of the inner lid 300. When the shapes of 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 are in close contact with each other. It has a high sealing property and can effectively prevent liquid leakage. In particular, since the lower arc portion 340 and the upper arc portion 350 have an arc shape, the contact area can be made larger, and further, since the lower arc portion 340 and the upper arc portion 350 have an arc shape, the fitting portion can be fitted even if an external force is applied. Since it is hard to shift, it is easy to maintain a state of close contact with each other and the sealing property is high.

Further, 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 separated from each other, and the container side. The lid 100 internally fitted to the fitting portion 460 and the inner lid 300 internally fitted to the container-side fitting portion 430 are also vertically separated from each other. Therefore, when the lid 100 is fitted to the container body 400, even if the lid 100 is pushed downward to be fitted, the inner fitting portion 130 and other parts of the lid 100 are internally fitted to the inner lid 300. It is possible to prevent the inner lid 300 and the container-side fitting portion 430 from being touched, and the fitting state of the inner lid 300 and the container-side fitting portion 430 is not affected. That is, since the fitted state of the inner lid 300 can be reliably maintained, the sealing property is high and liquid leakage can be effectively prevented. Similarly, when the lid 100 is removed from the container body 400, the inner fitting portion 130 and other parts of the lid 100 touch the inner fitting portion 330 and the container side fitting portion 430 of the inner lid 300. Since it can be prevented, the fitted state of the inner lid 300 can be reliably maintained, and liquid leakage can be effectively prevented.

Further, according to the container 500 of the present invention, as shown in FIG. 2, the inner fitting portion 130 of the lid 100 is a flat portion 132 continuous with the upper end 152 of the upper arc portion 150, or a lower arc portion 140. A flat portion 131 continuous with the lower end 141 is provided, and as shown in FIG. 7, the container-side fitting portion 460 corresponding to the inner fitting portion 130 also has a flat portion 461 having a shape matching the flat portion 131. Alternatively, a flat portion 462 having a shape that matches the flat portion 132 is provided. Therefore, when the flat portions are in close contact with each other, the contact area between the inner fitting portion 130 of the lid 100 and the container-side fitting portion 460 can be further increased. Further, since the flat portions are in contact with each other, the fitting portion between the inner fitting portion 130 of the lid 100 and the container-side fitting portion 460 is less likely to be displaced 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 a high sealing property, and liquid leakage can be effectively prevented.

Further, according to the container 500 of the present invention, as shown in FIG. 5, the inner fitting portion 330 of the inner lid 300 is a flat portion 332 or a lower arc portion 340 continuous with the upper end 352 of the upper arc portion 350. A flat portion 331 continuous with the lower end 341 is provided, and 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. Alternatively, a flat portion 432 having a shape that matches the flat portion 332 is provided. Therefore, when the flat portions are in close contact with each other, the contact area between the inner fitting portion 330 of the inner lid 300 and the container-side fitting portion 430 can be further increased. Further, since the flat portions are in 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 less likely to be displaced 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 a high sealing property, and liquid leakage can be effectively prevented.

Further, as shown in FIG. 10, in the container 500 of the present invention, the lid 100 is internally fitted to the container body 400 and sealed, but the present invention is not limited to this, and the container body is replaced with the lid 100. The container 500 may be sealed by heat-sealing a synthetic resin film on a part of the container-side fitting portion 460 on the upper stage of the 400. By heat-sealing the film, the airtightness can be easily improved. If the film is a part of the container-side fitting portion 460, the film is heat-sealed (heat welded) at an arbitrary place such as the flat portion 462 of the container-side fitting portion 460 or the vicinity of the upper end 482 of the upper arc portion 480. ) Can be done.

Further, as shown in FIG. 10, in the container 500 of the present invention, the inner lid 300 is internally fitted to the container body 400, but the present invention is not limited to this, and instead of the inner lid 300, the lower stage of the container body 400 A film made of synthetic resin may be heat-sealed on a part of the container-side fitting portion 430 of the above. By heat-sealing the film, the airtightness can be easily improved. If the film is a part of the container-side fitting portion 430, the film is heat-sealed (heat-welded) at an arbitrary location such as the flat portion 432 of the container-side fitting portion 430 or the vicinity of the upper end 452 of the upper arc portion 450. ) Can be done.

Further, as shown in FIG. 10, the inner fitting portion 130 of the lid body 100 of the present invention includes a lower arc portion 140 toward the inner space of the container 500. Since the length L2 of the lower arc portion 140 (see FIG. 2) is shorter than the length L1 of the upper arc portion 150, the lower arc portion 140 has higher rigidity than the upper arc portion 150 and is not easily deformed. In this way, since the lower arc portion 140 having high rigidity and being hard to be deformed is arranged closer to the internal space of the container 500, it is likely that liquid or the like will leak from the internal space of the container 500 to the outside. However, since the lower arc portion 140 is strongly adhered to the container-side fitting portion 460, liquid leakage can be effectively prevented. Further, when the container 500 is heated by a microwave oven, even if water vapor is generated from the internal space of the container 500, the lower arc portion 140 having high rigidity and not easily deformed is strongly fitted to the container side fitting portion 460. Therefore, the lid 100 does not come off vigorously due to water vapor.

Further, as shown in FIG. 10, the inner fitting portion 330 of the inner lid 300 of the present invention is provided with a lower arc portion 340 toward the side closer to the accommodating portion 403 of the container body 400. Since the length L4 of the lower arc portion 340 (see FIG. 5) is shorter than the length L3 of the upper arc portion 350, the lower arc portion 340 has higher rigidity than the upper arc portion 350 and is not easily deformed. In this way, since the lower arc portion 340, which has high rigidity and is not easily deformed, is arranged closer to the accommodating portion 403 of the container body 400, it is likely that liquid or the like will leak from the internal space of the container 500 to the outside. Even so, since the lower arc portion 340 is strongly adhered to the container-side fitting portion 430, liquid leakage can be effectively prevented. Further, when the container 500 is heated by a microwave oven, even if water vapor is generated from the storage portion 403 of the container main body 400, the lower arc portion 340, which has high rigidity and is not easily deformed, is strongly fitted to the container side fitting portion 430. Therefore, the inner lid 300 does not come off vigorously due to water vapor.

Next, how to remove the inner lid 300 of the container 500 of the present invention will be described with reference to FIG. Note that FIG. 11 shows a 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. FIG. 11A is a plan view of the state, and FIG. 11B is a plan view of the state. FIG. 5 is an end view of EE in this state. Further, in FIG. 11, for example, it is assumed that the purchaser of the container 500 containing the foodstuffs such as cold noodles eats the cold noodles, and the purchaser first removes the lid 100 from the container 500. The middle plate 200, which is removed and contains ingredients such as the flavor of cold noodles, is temporarily taken out from the container 500.

Next, as shown in FIG. 11, the purchaser picks the inner surface 321 and the outer surface 322 of the handle 320 with the fingers F1 (for example, the thumb) and the fingers F2 (for example, the index finger) of the hand, and pulls them upward. Then, starting from the hinge 313, the bottom wall 310 around the handle 320 is curved upward. Then, the inner fitting portion 330 on the handle 320 side and the container side fitting portion 430 of the container body 400 are disengaged. Subsequently, when the purchaser pulls up the handle 320 upward, the inner fitting portion 330'on the opposite side of the handle 320 and the container side fitting portion 430 are gradually disengaged, and the inner lid 300 is completely closed. It can be removed. Then, the purchaser tilts the inner lid 300 toward the accommodating portion 403 of the container body 400, and the noodles or the like (not shown) accommodated on the bottom wall 310 of the inner lid 300 are placed in the accommodating portion 403. Add to soup (not shown). Further, if the ingredients such as condiments stored in the once removed middle plate 200 are placed on the noodles and soup in the storage portion 403, the preparation for eating the chilled noodles is completed. Then, the purchaser can directly eat the cold noodles by using the container body 400 as a tableware.

As described above, 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, it is easy for a person to pick up the handle 320 with a finger and pull it up. Can be easily removed from the container body 400. In particular, since the handle 320 protrudes from the bottom wall 310, the force when the handle 320 is picked up is directly transmitted to the bottom wall 310, and is further provided on the outer edge of the bottom wall 310 from the bottom wall 310. It is effectively transmitted to the inner fitting portion 330. Therefore, the fitting between the inner fitting portion 330 and the container-side fitting portion 430 can be efficiently removed, and as a result, the inner lid 300 can be easily removed from the container-side fitting portion 430.

Further, 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 side, and the inner fitting portion located on the outside of the handle 320. The fitting strength of the 330 is weaker than the fitting strength of the inner fitting portion 330'located on the side opposite to the outside of the handle 320.
