Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a tub in which a small plate is assembled within a container, such as a sushi tub incorporating a sashimi plate.

(Prior art) If a bento box is considered to be a type of bucket, various forms of bento boxes have been used in recent years. A device in which a small container is placed inside a large container in the main body is used. Lunch boxes equipped with these small containers can store various side dishes without mixing them up with each other, and have been widely used in recent years, especially as a meal substitute at banquets and the like. Although the bucket according to the present invention is not a lunch box like this, it is the same when viewed as a food container in a broader sense, but for example, when a circular bucket as shown in Figure 6 is combined with a small plate as a small container. Also, in cases where a small container is placed inside the lunch box main container shown in Fig. 5 above, these small containers and main container are used as a pair.
The small container cannot be used as another main container. Therefore, when the crescent-shaped small plates of the circular bucket shown in FIG. 6 are assembled into buckets with different inner diameters, the curvatures of the trays are different and some gaps are created. At banquets, etc., there are cases where such combination containers are used, such as using the same small container and a larger main container, and sometimes using a smaller main container, or combining containers with completely different shapes.

(Problems to be Solved by the Present Invention) As described above, a tub that is integrated with a small plate as a small container is a pair of the small container and the main container, and the small container is not used for other purposes. It cannot be used as the main body container. The present invention was devised to solve this problem, and provides a tub with a small plate that can be used as a single small plate.

(Means for Solving the Problems) The small plate incorporated in the tub of the present invention has an asymmetrical outer shape for the purpose of dual use. The main container into which the small plate is incorporated has a circular edge or an edge with an arc formed at the corner, and the outer surface of the small plate is tightly fitted to a part of the edge. Moreover, the size of the radius of curvature of the other opposing outer surface of the small plate is
Unlike the curvature radius of the outer surface, which is in close contact with each other, it can be used in combination with other main containers.

EMBODIMENT OF THE INVENTION Hereinafter, one embodiment of the bucket with a small plate according to the present invention will be described in detail based on the drawings.

(Example) Figures 1 and 2 show one form of the tub with a small plate of the present invention, where the tub 1 serving as the main container is circular and has a rim 3 along the outer periphery. , the bottom 4 has a protruding leg 5. The inner circumferential surface 6 of the edge 3 has a radius of curvature from the center of _R1 ,
A small plate 2 whose entire surface on one side (hereinafter referred to as P surface 7) is in contact with the inner circumferential surface 6 is combined. Therefore,
The curvature of the P surface 7, which is the outer surface of the small plate 2, is the same as the radius of curvature _R1 of the inner peripheral surface 6, while the other surface (hereinafter referred to as the Q surface 8) also has a radius of curvature R1 of the inner peripheral surface 6. It is a circular arc with a constant radius of curvature, and its size R ₂ is
It is different from the radius of curvature _R1 of surface 7. Further, as shown in FIG. 3, a partition 9 is formed in one corner of the small plate 2, and the main container 1 is separated by the partition 9.
The depth of the auxiliary container 11 is relatively shallow compared to the depth of the main container 10. Furthermore, there are legs 12 protruding from the bottom,
Here, the cross-sectional shape of the small plate 2 and the auxiliary container part 1 are shown.
The presence or absence of the small plate 2 does not matter, and the form of the small plate 2 shown in FIGS. 1 and 2 is only one example belonging to the present invention.

FIG. 4 shows another embodiment, in which the main container shape of the tub 1 is approximately square, with large roundness formed at each corner. The outer surface P surface 7 of the small plate 2 having the same radius of curvature R ₃ as the radius of curvature R ₃ of the roundness is in close contact with the inner circumferential surface 6 of the edge 3 without any gap, and the P surface 7 of the small plate 2 Opposite Q surface 8
have different radii of curvature R ₄ .

By the way, the shape of the tub 1 is circular as mentioned above.
It is not limited to a substantially square shape, but may also be a diamond, rectangle, oval, etc., and the small plate 2 is placed at one corner of the tub 1, and the usage of such a tub is as follows:
For example, when used as a sushi tub, sushi can be placed in the tub body, sashimi can be placed in the small plate 2, and soy sauce can be placed in the auxiliary container 11 of the small plate.

As described above, the tub with a small plate according to the present invention has a small plate with opposing outer surfaces having different curvatures built into one corner of the edge 3 forming an arc with a predetermined curvature, and exhibits the following effects. obtain.

(Effects) (1) In this way, the opposing outer surfaces of the small plate are formed with different arcs of curvature, and two
It can be used as the main body of any type of bucket.

For example, in the case of a small plate that is combined with a circular bucket, if the curvature radii of the P surface 7 and Q surface 8, which are opposing outer surfaces, are R ₁ and R ₂ , it can be used for a bucket with radii R ₁ and R ₂ , respectively. be.

(2) By combining small plates within the main body of the tub, food is collected in one container without mixing with each other, and it is possible to select the size of the tub for the small plates, making it very suitable for the number of users. It's convenient.
