[Embodiment of device]

 An embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a perspective view showing a combination release state of the lunch box container of this embodiment. The lunch box container 1 is a disposable container used for housing, for example, a box lunch for sale, and includes a paper body container 2 having a rectangular bottomed box body and a paper container having a rectangular bottomed box body. It consists of a combination of a middle container 3 and a paper lid 4 which is also a rectangular box with a bottom.

The main body container 2 is, for example, a container that mainly stores rice (a side dish may be contained therein), and its four side surfaces 2a and 2b are slightly inclined outward from each side of the rectangular bottom surface 2c. It is a tapered surface that rises up.

The medium container 3 is, for example, a container mainly for storing side dishes (may contain rice), and its opening 3d has substantially the same size as the opening 2d of the main body container 2 and The depth is set to approximately half the depth of the main body container 2, and the four side faces 3a and 3b along the four side faces 2a and 2b of the main body container 2 are tapered side faces 2a and 2b of the corresponding main body container 2. And a taper surface having the same inclination angle. As a result, when the inner container 3 is superposed on the main container 2, the main container 3 is dropped to a depth of about ½ of the main container 2 as shown in FIGS. 2 (A) and 3. Since a resistance for preventing a drop is generated between the tapered side surfaces 2a, 2b of No. 2 and the tapered side surfaces 3a, 3b of the inner container 3 in contact therewith, the inner container 3 is fitted in the upper portion of the main container 2 in a state of being fitted therein. Can be supported. Further, in this case, since the complicated structure is not adopted for supporting the middle container 3, the main container 2 and the middle container 3 can be easily manufactured.

The lid 4 is fitted on the upper portion of the main body container 2 to cover the openings 2d and 3d of the main body container 2 and the middle container 3, and the four side surfaces 4a and 4b thereof are also inclined outward. It is a tapered surface that rises up. As a result, the tapered side surfaces 4a, 4a serve as guide surfaces, so that the lid 4 can be smoothly fitted onto the upper portion of the main body container 2.

In the work of filling the bento container 1 with the bento, the rice is stored in the lower half of the main body container 2, and the medium container 3 is stacked thereon. When used as a container for a lunch box for sale, the main container 2 has four side surfaces 2a and 2b as taper surfaces in the work of packing the lunch box, so that the taper side surfaces 2a and 2b are used as guide surfaces as shown in FIG. 4 (A). In addition, a large number of main body containers 2 can be prepared in a stacked state without being bulky. Also for the container 3 and the lid body 4, with the tapered side surfaces 3a, 3b, 4a, 4b used as guide surfaces, a large number of them are superposed as shown in FIGS. 4 (B) and 4 (C). It can be prepared in advance so that the work of packing lunches can be performed efficiently.

In the lunch container 1 of the above embodiment, the four side surfaces 2a, 2b of the main body container 2 and the corresponding four side surfaces 3a, 3b of the middle container 3 are tapered surfaces, but the main container 2 faces each other. The two side surfaces 2a, 2a (or 2b, 2b) are tapered surfaces, and the other two side surfaces 2b, 2b (or 2a, 2a) are vertical surfaces, and the inner containers 3 are opposed to each other correspondingly. The two side surfaces 3a, 3a (or 3b, 3b) may be tapered surfaces and the other two side surfaces 3b, 3b (3a, 3a) may be vertical surfaces. Also in this case, the middle container 3 can be supported on the upper portion of the main body container 2 with a simple configuration. Moreover, since the number of tapered surfaces is small, the volumes of the main body container 2 and the middle container 3 are increased accordingly, and the main body container 2 and the middle container 3 can be easily manufactured. Also in the case of the lid 4, the two side faces 4a, 4a (or 4b, 4b) may be tapered faces and the other two side faces 4b, 4b (4a, 4a) may be vertical faces.

Further, in the above embodiment, the lunch box container 1 is made of paper, but the invention is not limited to this, and it may be made of other material such as resin. Furthermore, in the said embodiment, although the case where the said lunch box container 1 was used as a container of a lunch box for sale was demonstrated, you may use it as a lunch box container for home use.
