Abstract

(57) [Summary] [Purpose] Conventionally, a lunch box container having a box-like shape composed of a synthetic resin body and a lid, for example, Japanese Utility Model Publication No. 52-32
A lunch box such as the No. 586 is known. However, in the above-mentioned lunch box, since the lids are stacked on top of each other, there are several steps in the stacking part, and it is difficult to remove dusts and the like when washing with water, and it is difficult to drain water. or,
Although there was a strong demand for novelty in terms of design, there was also the drawback that no measures such as this were taken. The present invention aims at providing a lunch box container, in particular a lid for a lunch box container, which eliminates the above-mentioned drawbacks. [Structure] An inclined overlapping corner portion 10 inclined from 30 ° to 70 ° is provided around the upper edge of the lid 3, and 30 ° to 30 ° corresponding to the inclined overlapping corner portion 10 is formed on the lower inner edge of the side wall 9.
The inclined overlapping portion 11 inclined at 70 ° is provided around the periphery.

[Industrial applications]

 This invention is to make many bento boxes of the same kind or almost the same kind at the same time at one time, and provide them to a large number of people at a lunch center, restaurant, drive-in, etc. The present invention relates to a lunch container, and more particularly to a lid of the lunch container.

[0002]

[Prior art]

 BACKGROUND ART Conventionally, as this type of lunch container, a heavy box-shaped container made of a synthetic resin container and a lid, for example, a lunch box such as Japanese Utility Model Laid-Open No. 52-32586 has been known and put to practical use. .

[0003]

[Problems to be solved by the device]

 However, in the above-mentioned lunch box, stacking the lids on top of each other is not stable, and there is a problem that it is difficult to remove and remove dust and the like when washing with water. In addition, there was a drawback in that it was lacking in freshness in terms of design.

[0004]

[Means for solving the problem]

 In view of this, in the present invention, the entire upper edge of the lid is provided with an inclined overlapping corner portion inclined at about 30 ° to 70 °, and the entire lower end inner edge of the side wall corresponds to the inclined overlapping corner portion. A tilted overlapped portion having a tilt of about 30 ° to 70 ° is provided around the circumference. The inclined overlapping corner portion and the inclined overlapping portion allow the lids to be easily stacked with each other without making them bulky. Further, since the overlapped portion has an oblique angle, no expansion or contraction occurs, and since the stacking step is one step, it is possible to easily remove dusts and water.

[0005]

[Action]

 In the lid according to the present invention, the inclined overlapping corner portion is provided around the entire upper edge portion and the inclined overlapping corner portion corresponding to the inclined overlapping corner portion is provided around the entire lower inner edge of the side wall. An outer overlapping portion is formed at the upper end portion, and an inner overlapping portion is formed at the lower end inner portion. Therefore, when stacking or storing multiple lids, stacking the next lid on the lower lid will guide the slanted angle to the outer overlapping portion of the lower lid and the inner overlap of the upper lid. The part is completely covered and fits.

[0006]

【Example】

 Next, the embodiment of the present invention will be described in detail with reference to the drawings. The bento container 1 is made of synthetic resin and is composed of a body 2 and a lid 3. The body 2 is for serving rice and dishes, and as shown in the drawing, the shape thereof is a box shape having a substantially square shape, and a side wall 5 is provided around the side edge of the bottom plate 4 to store the rice and dishes. 6 has been formed. Although not shown, a partition plate may be integrally molded in the storage unit 6 or manufactured as a separate body and fitted into the storage unit 6. Further, substantially L-shaped leg portions 7 are formed at portions located slightly inside the four corners of the bottom plate 4. The lid 3 is sized so that it can cover the upper end of the body 2, and a side wall 9 is provided below the side edge of the upper plate 8 as shown in the figure, and the entire corner portion of the upper plate 8 and the side wall 9 is 30 °. The inclined overlapping corner portion 10 inclined to ˜70 ° is provided around, and the inclined overlapping overlap portion 11 corresponding to the inclined overlap angle portion 10 is also provided around the entire lower end of the side wall 9. There is. The inclination angles of the inclined overlapping angle portion 10 and the inclined overlapping portion 11 are preferably 30 ° if one is 30 ° and 70 ° if the other is 70 °, but 2 °. A difference of about 5 ° is acceptable. In the figure, reference numeral 12 is a shallow recess provided on the surface of the upper plate 8, and the legs 7 in the case where the body 2 and the lid 3 are set and used as the lunch container 1 are inserted so that stacking can be performed easily and securely. However, it is not always necessary. It should be noted that although a substantially square shape is exemplified in the above embodiment, the shape is not limited to this, and it may be a rectangle, a polygon, a circle, an ellipse, or the like. In addition, a pattern may be applied from the upper plate 8 of the lid 3 to the inclined overlapping corner portion 10 and the side wall 9 or a lacquer finish may be applied.

The bento container 1 as described above is used as a lid 3 by placing rice and dishes in the storage portion 6 of the body 2, and placing a large number of lids 3 in a stacked state or storing them. In this case, if the next lid 3 is placed on the lower lid 3, it is guided by the inclination angle and the inner overlapped portion of the upper lid is completely covered by the outer overlapped portion of the lower lid, that is, the inclined overlapped portion. The corner portion 10 and the inclined overlapping portion 11 overlap with each other in a state of being joined to each other.

[0008]

[Effect of device]

 The lid 3 of the lunch container 1 according to the present invention has a side wall 9 provided around the lower side edge of the upper plate 8, and an inclined overlapping corner 10 is provided around the entire corners of the upper plate 8 and the side wall 9. Since the inclined overlapping portion 11 corresponding to the inclined overlapping corner portion 10 is provided on the entire inner side of the lower end of the side wall 9, the lids 3 can be stacked easily and reliably without rattling. In addition, since the stacks are in close contact, the bulk is minimized, and it is convenient because it does not take up much space for storage, etc., and because there are no stacking steps, dust that has adhered can be easily removed by washing with water. Hygiene can be maintained and draining is also effective. Also, since there is no structure surrounding the inclined overlapping corner portion 10 and the inclined overlapping portion 11 at all, it is very novel in terms of functionality and design, and has the effect of matching customer needs. .
