Generally, in a store that receives orders from customers and cooks and sells them on the spot, orders are concentrated at a specific time such as lunch time, so it is difficult to respond quickly to many customers.
Therefore, it is efficient to manufacture lunches that are expected to be ordered in advance, display freshly prepared lunches at the time when sales are concentrated, and allow customers to purchase the desired lunch boxes.
At this time, it is required to display the lunch box while keeping it warm so that it does not cool, but if you display the lunch box on the shelf for heat insulation, the problem is that salads, vegetables, seasonings etc. in the lunch box are also heated together there were.
The present invention was made in order to solve the conventional problems, and the purpose of the present invention is to set a portion where heat retention heat is likely to be transmitted and a region where heat is not easily transmitted to the container of the lunch box, and to the kind of foodstuff. Accordingly, an object of the present invention is to provide a lunch container that can accommodate each of them.

  As a means for achieving the above object, in the lunch box according to claim 1, in the lunch box provided with a container for storing food and a lid for covering the upper surface of the container, the container is formed with a partition to store foodstuffs. A plurality of storage portions are formed, and the bottom surfaces of some of the storage portions are arranged at positions higher than the bottom surfaces of the other storage portions.

  In the lunch container according to claim 2, in the lunch container according to claim 1, the lid includes a side surface rising upward and an upper surface bent in a horizontal direction from an upper end of the side surface. Grooves are formed.

  In the lunch container according to claim 3, in the lunch container according to claim 2, a trough portion whose upper surface is depressed downward passes through the lid, and the trough portion when the container is capped The partition line passes at a position corresponding to the passage line, and the lower end of the passage line in the valley of the lid is aligned with the upper end of the partition line of the container so that the lid is attached to the container.

  The lunch container according to claim 4 is the lunch container according to claim 3, wherein the passage line of the valley portion is curved in a plan view.

  The lunch container according to claim 5 is characterized in that in the lunch container according to any one of claims 1 to 4, a part of the bottom surface of the storage part is depressed to form a water droplet storage part.

By adopting the above configuration, the present invention has the following effects.
In the lunch box according to the present invention, the bottom surface of some of the storage portions is arranged at a position higher than the bottom surface of the other storage portions, so that when the lunch box is displayed on a shelf for heat insulation, Parts that are difficult to communicate are set. Therefore, it can accommodate in a suitable accommodating part according to the necessity of the heat insulation of a foodstuff.

Since the lid includes a side surface that rises upward and an upper surface that is bent in the horizontal direction from the upper end of the side surface, the lid has a height and a large storage space for foodstuffs is formed inside.
Since a groove is formed in the vertical direction on the side surface of the lid, water droplets adhering to the side surface are guided by the groove and flow down.

  A trough whose upper surface is depressed downward passes through the lid, and a partition line passes through the container at a position corresponding to the passage line of the trough when the lid is capped. Since the lower end of the passage line is aligned with the upper end of the partition line of the container and the lid is attached to the container, the trough portion provides strength to support the load applied to the upper surface of the lid. In other words, because the lid has a raised side and secured height, there is a risk of crushing due to the load when cooked rice or other lunch containers are stacked on top of the lunch box. Since the upper end of the partition line is in contact, this portion serves as a column and supports the load applied to the upper surface.

Moreover, since the lower end of the passage line of the valley part of the lid is aligned with the upper end of the partition line of the container, a partition is formed in the internal space of the lunch box.
In other words, if the upper space of the storage section is secured wide, the foodstuff will be displaced when carrying the lunch box, but the line-shaped valley part and the partition are combined to partition the space, so the foodstuff is scattered over the partition. It will not come off.

  Since the passage line of the valley is curved in a plan view, the strength against the bending force is given compared to the straight line.

  Since a part of the bottom surface of the storage part is depressed to form a water droplet storage part, water droplets generated by heat retention are stored in the storage part and do not adhere to the food.

  Hereinafter, the best mode for realizing the lunch box of the present invention will be described with reference to the drawings.

  As shown in FIGS. 1-19, the lunch box of this invention consists of the container 1 which accommodates a foodstuff, and the lid | cover 2 which covers the upper surface of the container 1, and is a container which accommodates a side dish (a side dish). At the time of use, the cooked rice container is used by being stacked on the main body.

The container 1 has a peripheral outer peripheral edge 3, a side surface 4 bent obliquely downward from the edge 3, and an accommodating portion 5 surrounded by an elliptical shape by the side surface 4, and a partition is formed in the accommodating portion 5. A plurality of raised portions having different sizes are formed.
The side surface 4 and the partition are arranged with an inclination, and each serving portion is provided with an inclination that opens upward.
The upper end of the side surface 4 of the container 1 is bent outward to form an edge 3 having a predetermined width. This edge 3 functions as an attachment portion for the lid 2, and an attachment portion 24 for the lid 2 overlaps the upper surface of the edge 3. The outer periphery 25 of the lid 2 is fitted into the outer edge of the edge 3.
Wide portions are formed at the four corners of the edge 3, and folds 6 are formed at three locations on the wide portions, respectively, and subjected to reinforcement processing.
The outer shape of the entire container is, for example, a shape having a horizontal diameter of 22 cm, a vertical diameter of 17.5 cm, and a depth of several centimeters.

The container 1 is a flexible resin material having a uniform thickness, and is made of a white material having heat retention. In addition, a raw material can be suitably set according to the foodstuff etc. to apply.
The container body is formed by molding a thin plate-like resin material by mold forming, and when the containers are stacked up and down, each container can be stacked and stored in a state in which the irregularities are complementarily overlapped and closely adhered. .

The storage unit 5 is a space for serving side dishes or containing seasonings, and includes a first storage unit 7 for storing side dishes as main ingredients, a second storage unit 8 for storing vegetables such as salads, dressings, seasonings, and the like. The 3rd accommodating part 9 which accommodates, and the 4th accommodating part 10 which accommodates pickles are provided.
Each of the first to fourth housing portions is divided by a partition, and the partition further divides the main housing line 11 that divides the entire housing portion into two, and one side of the housing portion divided by the main partition line 11. It consists of a sub-divided line 12 and branch lines 13 and 14 that are branched from the front of the main divided line 11.
The main dividing line 11 extends obliquely from the upper right to the lower left of the container, the sub dividing line 12 extends outward from the middle of the main dividing line, and the branch lines 13 and 14 extend from the front of the main dividing line 11 to the left and right. The branches branch shortly and each side reaches the side surface 4.

The first accommodating portion 7 is a portion surrounded by the side surface 4, the main dividing line 11 and the front branch line 14, and is a wide space that occupies an oblique half of the container 1.
The second accommodating portion 8 is a portion surrounded by the side surface 4, the main dividing line 11, the preceding branch line 13, and the sub dividing line 12, and is set to be substantially half of the first accommodating portion 7 or slightly narrower than that. Yes.
The third accommodating portion 9 is a portion surrounded by the side surface 4, the main dividing line 11 and the sub dividing line 12, and is set narrower than the second accommodating portion 8.
The 4th accommodating part 10 is the site | part enclosed by the side surface 4 and the two branch lines 13 and 14, and becomes the narrowest space in an accommodating part.

  The main division line 11, the sub division line 12, and the branch lines 13 and 14 are in a state where the bottom of the container is pushed up by mold forming. The wall height at the end of the main dividing line (around 2 cm in the vicinity of the side surface) gradually decreases toward the end. That is, the intermediate part line indicated by R in FIG. 1 has a high wall height and passes horizontally, and both end directions following the R part gradually drop. The wall height of the intermediate part of the main dividing line 11 is approximately the same as that of the side surface, and this intermediate part line passes correspondingly to the lower end line 28 of the valley portion 22 of the lid 2 described later.

The bottom surface of the first housing part 7 is formed deeper than the other housing parts. Three streaky convex portions 15 pass through the bottom at a predetermined interval. Since the three convex portions 15 are formed, the side dishes of the housing portion are placed on the convex portions 15 and are not in close contact with the bottom, thereby preventing moisture from adhering to the bottom.
A recessed groove 16 is formed along the lower end of the side surface 4 at the bottom of the first accommodating portion 7, and the recessed groove 16 serves as a storage portion for storing water flowing down along the side surface 4. Since the bottom of the groove 16 is depressed, the back side protrudes downward, and this protruding portion functions as a grounding portion when the container is placed. The groove 16 occupies about a half of the entire circumference of the elliptical accommodating portion, and this portion and a groove 17 which will be described later are grounded to stably support the main body.
In this embodiment, the groove 16 is depressed, but it is also possible to separately set a boundary line between the groove 16 and the bottom without being depressed. In this case, the height level of the groove 16 and the bottom becomes the same, and when the container is placed on the heat insulating shelf, both the groove 16 and the bottom of the first housing portion 7 are grounded.

A groove 17 is formed along the bottom of the side surface of the bottom of the second housing portion 8. The groove 17 protrudes downward and the bottom surface is disposed at a position higher than the first housing portion 7 with a step. . Therefore, heat from the bottom is not easily transmitted, and vegetables such as salad can be placed on the heat insulation shelf while avoiding heat.
The bottom of the 3rd accommodating part 9 is arrange | positioned in the position higher than a 2nd accommodating part, and is shallow. The bottom of the 4th accommodating part 10 is arrange | positioned in the position higher than the 3rd accommodating part 9, and is still shallower.
When the container 1 is placed on the shelf, the groove 16 of the first housing portion 7 and the groove 17 of the second housing portion 8 serve as a grounding portion, and the bottoms of the third housing portion 9 and the fourth housing portion 10 are raised. It is difficult to receive heat and can be stored according to the type of food.

The lid 2 includes a side surface 20 rising upward, and an upper surface 21 bent in the horizontal direction from the upper end of the side surface 20. The upper surface 21 has a valley 22 recessed in a V shape and positioning when the rice container is stacked. The convex part 23 is formed (refer FIGS. 10-18).
The lid 2 is formed of a thin plate-like transparent resin material having an elliptical shape in plan view, and is integrally formed by mold forming like the container 1.
The lower end of the side surface 20 is bent outward to form a mounting portion 24 having a predetermined width. The mounting portion 24 abuts on the edge 3 of the outer periphery of the container, and the outer peripheral piece 25 of the mounting portion 24 is fitted to the edge 3 of the container. It comes to include.

Although the outer periphery of the side surface 20 is partly cut by the valley portion 22, when the cut portions are connected, it has the same width as the opening of the side surface 4 of the container 1 and is aligned with the upper end of the side surface 4 of the container 1. The lower end of the side surface 20 of the lid 2 is connected. The side surface 20 has a slope that opens downward.
A large number of grooves 26 are arranged in parallel in the vertical direction on the inner side of the side surface 20, and except for some grooves, the upper portion of the grooves 26 is short and bent horizontally.
The longitudinal groove 26 is formed by making the side surface 20 concave and convex in an arc shape, the groove width is set to 4 to 6 mm, and the depth is 1 to 2 mm, and the groove 26 continuously extends from side to side and covers substantially the entire circumference of the side surface. ing.
Since the lid 2 is formed of a thin plate-like resin material, an arc-shaped convex portion corresponding to the groove 26 is formed on the outside of the side surface, and bending strength is given by the groove.
Since the groove 26 is formed on the side surface 20, water droplets adhering to the inside of the lid 2 flow down to the side surface through the groove and are eliminated.

On the upper surface 21 of the lid 2, a valley portion 22 that is depressed in a V shape is formed, and this valley portion 22 forms a curved line from the upper right to the lower left side of the upper surface of the lid 2.
The valley portion 22 has a planar side surface 27, and the planar side surface converges downward from the upper surface, and the converged lower end is a lower end line 28 having a width of several millimeters.
The height level of the lower end of the valley portion 22 is the same level as the lower end of the side surface 20, and the space inside the side surface 20 is divided into two by the valley portion 22.
When the lid 2 is attached to the container 1, the lower end line 28 of the valley portion 22 of the lid 2 is aligned with the upper end of the main dividing line 11 of the container 1, and the inner space of the container is the lower end line 28 of the valley portion and the main dividing line. 11 is partitioned. The internal space is partitioned by this partition, and the shift of food when carrying the lunch is prevented.
Moreover, when the lines of the lower end line 28 and the main dividing line 11 (intermediate part line indicated by R in FIG. 1) are combined, this part functions as a pillar or wall surface that supports the upper surface 21, and the lunch container or cooked rice container is Supports the load when stacked on top.
In addition, although the lower part line 28 and the intermediate part line of the main division line 11 contact | abut, the part is obstruct | occluded, but since the wall height of a partition line is low, the clearance gap will arise slightly. However, it is also possible to change the shape of the lower end line 28 or the partition line so that the gap contacts the both so that there is no gap.

A method for using the lunch box of the present invention will be described.
The first storage part 7 of the container 1 stores the main dishes, the second storage part 8 stores vegetables such as salads, the third storage part 9 stores dressings, seasonings, and the fourth storage part 10 stores pickles. Put the lid on the display shelf for heat insulation.
At this time, since the bottom of the second storage portion 8 is set high by the groove 17 and the third to fourth storage portions are arranged at positions raised from the shelf, it is difficult for heat to be transmitted to the food.
Since a groove 26 is formed on the side surface 20 of the lid 2 in the vertical direction, water droplets adhering to the side surface due to heat insulation are guided by the groove 26 and flow down, and the water droplets that have flowed down are stored in the grooves 16 and 17 to be used as food. Does not adhere.
Since the lower end line 28 through which the valley portion 22 of the lid 2 passes is fitted to the upper end of the main dividing line 11 of the container 1 and the lid 2 is attached to the container 1, the strength that supports the load applied to the upper surface of the lid 2 by the valley portion 22 is high. It is possible to stack and display lunch boxes.
In addition, since the lower end of the passage line in the valley portion of the lid 2 is aligned with the upper end of the partition line of the container, there is no possibility that the food is shifted beyond the partition when the partition is formed in the internal space of the lunch box and the lunch box is carried.
Since the positioning convex part 23 with respect to the bottom of the cooked rice container is formed on the upper surface of the lid 2, the cooked rice container is used by overlapping the convex part 23.
