FIG. 3 is a diagram illustrating a direction confirmation pattern of a lunch container according to an embodiment of the present invention.

Next, a specific example of a form for implementing the lunch container according to the present invention will be described in detail with reference to the drawings.
FIG. 1 is a sectional view schematically showing the overall structure of a lunch container according to an embodiment of the present invention.
Referring to FIG. 1, a lunch container 1 according to an embodiment of the present invention includes a first container 30 for storing food to be heated in an outer box 10 made of paper, a second container 40 for storing food to be heated, and a second container 40 for storing food to be heated. It includes a frame 50 that floats and supports the container 40, and an accessory 60 such as chopsticks.

The first container 30 is composed of a first container main body 31 and a first container lid 32, both of which are made of paper. It has the shape of a rectangular stand that is inverted. This shape is just one embodiment, and it may be a rectangular parallelepiped in which the bottom and top openings are the same size.

The main body 31 of the first container is for storing warming foods such as rice and grilled meat inside, and is taken out from the outer box 10 together with the lid 32 of the first container and heated in a microwave as is. It is made of paper that is water-resistant, oil-resistant, and heat-resistant so that it can warm the food. Various methods have been put into practical use to make food-grade paper water-resistant, oil-resistant, and heat-resistant, such as film lamination, fluororesin processing, and improving the fiber density of the paper itself. The paper used for No. 30 may be any type of paper treated as long as it can be used for food and has the above-mentioned characteristics.

In the embodiment, since the main dishes are arranged on top of the rice to be heated together, no partition is provided inside the main body 31 of the first container, but it is necessary to prevent multiple types of main dishes from being mixed together. When packing in sections, a partition plate made of paper made of the same material as the first container body 31 is erected inside the first container body 31 to divide the inside of the first container body 31 into a plurality of spaces. Good too.

The lid 32 of the first container is configured to be placed over the main body 31 of the first container, and includes a rectangular top surface 34 that covers the opening on the top surface of the main body 31 of the first container, and each side of the top surface 34. It is provided with a bending part 35 which is bent downward toward the main body 31 side of the first container. One of the four folded parts 35 is provided with two cuts extending from the lower end toward the top surface 34 in the folded state, and only the part between the two cuts can be folded upward or folded back as is. , is used as a knob 33 that makes it easier to open the lid 32 of the first container. Although the lid 32 of the first container does not come into direct contact with the food to be heated, it may be exposed to steam rising from the food to be heated or oil splashed during heating in a microwave oven. As with the main body 31, paper is used that is water resistant, oil resistant, and heat resistant. The lid 32 of the first container is used to cover the main body 31 of the first container, and since the lid 32 of the first container does not have a high airtightness, even if warm food is filled, moisture such as steam will not escape from the first container. It is difficult to get trapped inside the container 30.

The second container 40 is a container for storing foodstuffs that are not heated, and is composed of a second container main body 41 and a second container lid 42.
The main body 41 of the second container includes a plurality of accommodating portions 44 in order to provide a plurality of unheated foods without mixing with each other. In one embodiment, four accommodating portions 44 of different sizes are provided. Further, among the four accommodating portions 44, the two accommodating portions 44 having a small upper opening area and the two accommodating portions 44 having a large upper opening area are formed to have different depths.

There are no particular restrictions on the number of accommodating parts 44 and the size and depth of each accommodating part 44, and the number of accommodating parts 44 may be more or less than four, and the depth of the accommodating parts 44 may be the same, or the number of accommodating parts 44 may be the same. It may be different for every 44. However, in the embodiment, even the deepest accommodating part 44 is not deeper than the thickness of the main body 31 of the first container.

The purpose of separating the storage portions 44 in this way is to prevent the influence of juicy ingredients from spreading to other ingredients, as well as to prevent the aroma of foods with strong aromas from transferring to other ingredients. It can also play a protective role. For this reason, the lid 42 of the second container was also aligned with the divisions of the accommodating portions 44 of the main body 41 of the second container, and each accommodating portion 44 was aligned with the accommodating portion 44 of the main body 41 of the second container so as to properly cover the respective accommodating portions 44. formed as a shape. Specifically, as shown in FIG. 1, the lid 42 of the second container is formed with a protruding portion near the outer periphery so as to fit into the recess of the main body 41 of the second container. At the partition wall portion, a protrusion is provided to sandwich the partition wall portion. In the embodiment, the lid 42 of the second container is press-fitted into the main body 41 of the second container so as to have a certain degree of airtightness.

Since the main body 41 of the second container and the lid 42 of the second container have a complicated shape, in the embodiment, the main body 41 of the second container and the lid 42 of the second container are made of transparent polyethylene so that the contents can be seen. Molded by press processing using terephthalate (PET) resin. During molding, a flange portion 43 is formed on the outer periphery of the second container main body 41 and the second container lid 42 for support and ease of handling. The resin and processing method used for molding shown here are just one embodiment, and the materials and processing method are not limited to these as long as the required shape and function can be obtained.

The lid 42 of the second container is fitted over the main body 41 of the second container and may be difficult to remove from the main body 41 of the second container. The portion 45 is formed so as to protrude from the outer periphery.

The frame body 50 is disposed adjacent to the first container 30 in the outer box 10, defines a storage position of the first container 30, and supports the second container 40. The frame 50 is made of paper and has a square tube shape, and has an opening 51 on the upper surface into which the main body 41 of the second container is inserted, and supports the flange 43 around the opening 51 to insert the main body 41 of the second container. The second container 40 is floated and supported so that its upper end is at the same height as the first container 30.

As mentioned above, the depth of the accommodating part 44 of the main body 41 of the second container may vary depending on the accommodating part 44, and in that case, if it is placed directly in the outer box 10, the main body 41 of the second container will tilt. It will end up being put away. Since the frame body 50 supports the flange portion 43 around the opening portion 51, it is possible to horizontally support the main body 41 of the second container even if the depth varies depending on the accommodating portion 44. Furthermore, even if the entire accommodating portion 44 of the main body 41 of the second container is relatively shallow, by making the height of the frame 50 substantially match the height of the first container 30, the first container 30 and the second container 40 can be placed side by side. It can be stored nicely.

As shown in FIG. 1, the second container 40 is separated from the first container 30 and is stored with the accommodating portion 44 floating in the air. Even if the first container 30 is accommodated therein, the structure is such that it is not easily affected by heat from the contents of the first container 30. Further, by taking advantage of the fact that there is a space between the bottom of the second container 40 and the outer box 10, an ice pack or the like is placed in this space to suppress the temperature rise of the food inside the second container 40. You can use it like this. Unlike paper, which is the material used for the first container 30, the frame 50 is not required to have any better characteristics as long as it can support the second container 40, but if an ice pack or the like is used, it will be affected by condensation. The paper used to form the frame 50 is water resistant.

The accessories 60 include chopsticks for serving food. Other examples of the accessories 60 include instructions for heating in a microwave oven, an apron, a side dish, a hand towel, a toothpick, and the like. In one embodiment, when the food contains foods that tend to cause bad breath after eating, it includes a bad breath care product such as gum or tablets to suppress bad breath or freshen the mouth. Depending on the ingredients, a spoon or fork may be provided instead of or in addition to chopsticks. The accessories 60 do not need to include all of the above items, and may be placed on the first container 30 and the second container 40 in an appropriate combination depending on the food contained in the lunch container 1. When the accessory 60 is a combination of the above-mentioned plurality of articles, the plurality of articles may be stored together in one bag or may be stored individually.

The outer box 10 includes an outer box main body 11 and an outer box lid 20, and the outer box main body 11 is higher than the first container 30 housed inside and the second container 40 supported by the frame 50. It is formed as high as at least the height necessary to place the accessory 60, and the lid 20 of the outer box can be placed on it without lifting up. After storing the first container 30, the second container 40 supported by the frame body 50, and the attachment 60 in the main body 11 of the outer box, and after covering the lid 20 of the outer box, a colored rubber band (not shown) is attached. Hook it on one corner of the lid 20 of the outer box, go around the bottom of the main body 11 of the outer box, and hook it on the other corner diagonally of one corner of the lid 20 of the outer box. to fix the outer box main body 11 and the outer box lid 20. This completes the bento.

FIG. 2 is a plan view schematically showing the storage state of the first and second containers of the lunch container according to the embodiment of the present invention.
Referring to FIG. 2, the first container 30 and the second container 40 supported by the frame 50 are housed side by side in the main body 11 of the outer box. FIG. 2 shows a state in which the first container 30 and the second container 40 are covered with a lid 32 of the first container and a lid 42 of the second container, respectively.

The lid 32 of the first container includes a top surface 34 that covers the opening of the main body 31 of the first container, and bent portions 35 that are individually bent from the four outer periphery sides of the top surface 34 toward the main body 31 of the first container. As shown on the right side in FIG. 2, two cuts are made in the folded part 35 on one of the four sides, dividing the folded part 35 into three parts, of which only the middle part is cut. is bent upward, which is the opposite direction to the main body 31 of the first container. This upwardly bent portion becomes the knob portion 33. FIG. 2 shows a state in which the knob 33 is further folded back toward the top surface 34.

The lid 42 of the second container is formed in such a shape as to cover each accommodating part 44 in accordance with the shape and arrangement of the accommodating part 44 of the main body 41 of the second container. The embodiment shown in FIG. 2 shows a state in which unevenness is formed to correspond to four accommodating parts 44, which are two longitudinally elongated accommodating parts 44 and two shorter accommodating parts 44. A flange portion 43 is formed on the outer periphery of the lid 42 of the second container so as to overlap the flange portion 43 of the main body 41 of the second container, and these flange portions 43 are supported around the opening 51 of the frame 50. As a result, the second container 40 is supported with its bottom surface floating.

As shown on the lower right side of the lid 42 of the second container in FIG. 2, a knob 45 is formed to protrude further from the flange 43 to the outer periphery. In the embodiment, the knob portion 45 is knurled for easy picking. The lid 42 of the second container is attached to the main body 41 of the second container in a press-fitted manner so that the juice and aroma of the ingredients in the storage section 44 are unlikely to leak out, so the knob 45 makes it easy to remove the lid 42 of the second container. It is something to do. Moreover, since the knob portion 45 protrudes so as to overlap with the first container 30 side, by storing the second container 40 from behind the first container 30, the first container 45 can be placed over the main body 31 of the first container. It also serves to prevent the lid 32 of the container from lifting up.

Furthermore, the knob 33 of the first container 30 and the knob 45 of the second container 40 are located in the same direction when the first container 30 and the second container 40 are correctly arranged in a predetermined direction. Since it is provided on the side, it also serves to prevent the container from being oriented incorrectly by storing the container so that both the knobs (33, 45) are oriented in the same direction. In the embodiment shown in FIG. 2, the correct arrangement is to accommodate both the knobs (33, 45) on the right side.

FIG. 3 is a perspective view showing the shape of the frame of the lunch container according to the embodiment of the present invention.
Referring to FIG. 3, the frame 50 is formed into a square tubular shape, and an opening 51 is provided on the top surface. In the embodiment, the opening 51 is provided at a position biased toward one side. Therefore, when the main body 41 of the second container is inserted into the opening 51, the main body 41 of the second container is inserted into the upper surface around the opening 51 in a planar shape on three sides, and in a straight line at the vertex of the side wall on one deviated side. The flange portion 43 of 41 is supported. By doing so, a state in which the knob 45 of the second container 40 protrudes toward the first container 30 is realized.
In FIG. 3, an embodiment is shown in which the top surface of the frame remains on three sides: the back side, the front side, and the left side, but in other embodiments, the left side and the right side are open. Similarly, it may be opened so as not to leave the top surface of the frame. In this case, by making the openings the same size and matching the width of the frame 50 with the main body 41 of the second container, the state in which the knob 45 of the second container 40 protrudes toward the first container 30 can be prevented as in the above case. It can be realized.

FIG. 4 is a perspective view showing the shape of the lid of the outer box of the lunch container according to the embodiment of the present invention.
Referring to FIG. 4, the outer box lid 20 according to the embodiment of the present invention includes a top surface 24 and a bending portion 21 that is bent toward the main body 11 of the outer box at each side around the top surface 24. As shown in FIG. In the folded state, the side portions of at least three of the bent portions 21 on adjacent sides are joined to each other at the joining portions 22. Furthermore, a fold line 23 for folding at least one side of the four-side folding section 21 is provided on the folding section 21 joined adjacent to the folding section 21 to be folded.

The fold line 23 is formed to be a valley fold line when viewed from the inside of the lid 20 of the outer box, and a mountain fold line when viewed from the outside. In the embodiment shown in FIG. 4, the folding portions 21 shown on the upper and lower sides are configured to be foldable, and thus creases 23 are formed in the bending portions 21 shown on the left and right sides, respectively. One side of the bent portion 21 shown on the upper side is joined at a joining portion 22, but the other side is cut out and is not joined. Therefore, it can be folded more easily than the bending portion 21 on the lower side.

The folded bent portion 21 can be easily inserted under the main body 11 of the outer box. Therefore, after opening the lid 20 of the outer box, by folding the bent part 21 on one side and stacking it under the main body 11 of the outer box, there is no problem in finding a place to store the lid 20 of the outer box even in a narrow space. In addition, by folding the bent part 21 on one side, the outer box can be overlapped even if it is slightly shifted from the main body 11. You can also temporarily store items that will not be needed during meals.
