Description

The present invention relates to a lunch box container, particularly in an outer box made of paper, in which foods to be warmed and foods not to be warmed are stored in separate containers and arranged side by side with good appearance, while suppressing the amount of plastic material used. To provide a convenient lunch container.

Bento containers have been devised and put into practical use in a wide variety of forms depending on the purpose and usage. Bento containers can be broadly divided into individual bento containers that individuals carry around and use repeatedly, and disposable bento containers that are provided by restaurants and food processing manufacturers and used for home delivery or takeout. can.
In the case of a disposable lunch box container, it is common to use a resin material such as by pressing a resin sheet or injection molding a resin material. With such a processing method, if a metal mold is manufactured, it is possible to stably mass-produce bento lunch containers having various shapes of accommodating portions, and to manufacture bento lunch containers at a relatively low cost.

Patent Document 1 is an example of a disposable plastic food packaging container, and Patent Document 1 describes a container body divided into a plurality of compartments by partition ribs and a lid covering the entire opening of the container body. A packaging container is described.

Patent document 2 is also an example of a lunch box made of plastic. Patent document 2 describes a synthetic resin lunch box provided with a container body having a plurality of storage spaces inside and a lid covering the container body. Among the containers, a lunch container is described which further comprises an auxiliary container for sealing within the storage space.

Next, specific examples of the form for carrying out the lunch box container according to the present invention will be described in detail with reference to the drawings.
FIG. 1 is a cross-sectional view schematically showing the overall configuration of a lunch box container according to an embodiment of the present invention.
Referring to FIG. 1, a lunch box container 1 according to an embodiment of the present invention includes a first container 30 for storing foods to be warmed in an outer box 10 made of paper, a second container 40 for storing foods not to be heated, and a second container 40 for storing foods to be warmed. A frame 50 for floating and supporting the container 40 and an accessory 60 such as chopsticks are provided.

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

The main body 31 of the first container accommodates food for warming such as rice and grilled meat inside. It is made of water-, oil-, and heat-resistant paper so that food can be warmed. Various methods such as film lamination, fluororesin processing, and improvement of the fiber density of the paper itself have been put into practical use as techniques for imparting water resistance, oil resistance, and heat resistance to food paper. The paper used for 30 may be any kind of processed paper as long as the above characteristics are obtained for food.

In the embodiment, since the main dishes to be warmed together are provided on top of the rice, no partition is provided inside the main body 31 of the first container. In the case of separately packing, a partition plate made of paper made of the same material as the main body 31 of the first container is erected in the main body 31 of the first container to partition the interior of the main body 31 of the first container into a plurality of spaces. good too.

The lid 32 of the first container is configured to cover the main body 31 of the first container, and has a rectangular top surface 34 covering the opening of the top surface of the main body 31 of the first container from above, and each side of the top surface 34. and a bending portion 35 that is bent from the bottom toward the main body 31 side of the first container. One of the four folding parts 35 is provided with two cuts directed from the lower end to the top surface 34 in the folded state, and only the part between the two cuts is folded upward or folded as it is. , as a knob 33 that facilitates opening the lid 32 of the first container. The lid 32 of the first container does not come into direct contact with the warming food, but it may be exposed to steam rising from the warming food or oil that scatters during the heating process in the microwave oven. As with the main body 31, water-, oil-, and heat-resistant paper is used. The lid 32 of the first container is used so as to cover the main body 31 of the first container, and the sealing property of the lid 32 of the first container is not high. It is difficult to stay inside the container 30 .

The second container 40 is a container for storing foods that are not to be heated, and is composed of a second container main body 41 and a second container lid 42 .
The body 41 of the second container comprises a plurality of receptacles 44 for providing a plurality of refrigerated foodstuffs that do not mix with one another. In one embodiment, the plurality of accommodating portions 44 is provided with four different sizes. Further, among the four housing portions 44, the two housing portions 44 having a small upper opening area and the two housing portions 44 having a large upper opening area are formed to have different depths.

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

The compartments 44 are divided in this way, in addition to preventing the influence of juicy foodstuffs from circulating in other foodstuffs, and also preventing the scent of strong-scented foodstuffs from transferring to other foodstuffs. It can also play a preventative role. Therefore, the lid 42 of the second container is also aligned with the section of the storage section 44 of the main body 41 of the second container, and each storage section 44 is aligned with the storage section 44 of the main body 41 of the second container so as to properly cover. Formed as a shape. Specifically, as shown in FIG. 1, the lid 42 of the second container has a protruding portion formed in the vicinity of the outer circumference thereof so as to fit into the concave portion of the main body 41 of the second container, and serves as a boundary separating the accommodating portion 44 . A protrusion is provided so as 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 working using terephthalate (PET) resin. A flange portion 43 is formed on the outer periphery of the main body 41 of the second container and the lid 42 of the second container in order to support and facilitate handling during molding. The resin used for molding and the processing method shown here are one embodiment, and the material 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 put on the main body 41 of the second container so as to fit thereon, and there is a risk that it 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 50 is arranged adjacent to the first container 30 within the outer box 10 , defines the housing position of the first container 30 and supports the second container 40 . The frame 50 is made of paper and formed in a square tubular shape, and has an opening 51 on the upper surface thereof into which the main body 41 of the second container is inserted. The second container 40 is floated and supported such that the upper end is at the same height as the first container 30 .

As described above, the depth of the storage portion 44 of the main body 41 of the second container may vary depending on the storage portion 44. In this case, if the main body 41 of the second container is placed directly in the outer case 10, the main body 41 of the second container may tilt. I will put it away. Since the frame 50 supports the flange portion 43 around the opening 51 , it can horizontally support the main body 41 of the second container even if the depths of the housing portions 44 are different. In addition, even when the entire accommodating portion 44 of the main body 41 of the second container is relatively shallow, the first container 30 and the second container 40 can be arranged side by side by substantially matching the height of the frame 50 with the height of the first container 30. It looks nice and can be stored.

As shown in FIG. 1, the second container 40 is separated from the first container 30 and stored with the storage portion 44 floating in the air. , the structure is such that it is less likely to be affected by heat from the contents of the first container 30 . In addition, using the space between the bottom of the second container 40 and the outer box 10, a cooling agent or the like is placed in this space to suppress the temperature rise of the food in 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 more characteristics as long as it can support the second container 40. However, if a cooling agent or the like is used, the frame 50 is affected by condensation and the like. Water-resistant paper is used for forming the frame 50 .

Appendages 60 include chopsticks and the like for serving foodstuffs. The attachments 60 may also include a manual for heating in a microwave oven, an apron, a side sauce, a towel, a toothpick, and the like. In one embodiment, when foods that tend to cause bad breath after eating are included, a bad breath care product such as a gum or tablet is included to control 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 attachments 60 do not need to include all of the above items, and are placed on the first container 30 and the second container 40 in an appropriate combination according to the foodstuffs to be accommodated in the lunch container 1 . When the accessory 60 is a combination of the plurality of items described above, the plurality of items may be put together in one bag and then stored, or may be stored individually.

The outer box 10 includes a main body 11 of the outer box and a lid 20 of the outer box. It is formed at least as high as the height required to place the accessory 60, and the lid 20 of the outer box is covered without lifting. After housing the first container 30, the second container 40 supported by the frame 50, and the accessory 60 in the main body 11 of the outer box, and then covering the lid 20 of the outer box, a colored rubber band (not shown) is hooked on one corner of the outer box lid 20, then wraps around the bottom surface of the outer box body 11 and hooks on the other diagonal corner of one corner of the outer box lid 20. to fix the main body 11 of the outer box and the lid 20 of the outer box. This completes the bento box.

FIG. 2 is a plan view schematically showing the accommodation state of the first and second containers of the lunch container according to the embodiment of the present invention.
Referring to FIG. 2, a first container 30 and a second container 40 supported by a 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 the first container lid 32 and the second container lid 42, 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 bending portions 35 that individually bend from four sides of the outer periphery 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 portion 35 on one of the four sides to divide the folded portion 35 into three, and only the middle portion is folded upwards in a direction opposite to the body 31 of the first container. This upwardly bent portion serves as the knob portion 33 . FIG. 2 shows a state in which the knob portion 33 is further folded toward the top surface 34 .

The lid 42 of the second container is formed in such a shape as to cover the respective accommodating portions 44 according to the shape and arrangement of the accommodating portions 44 of the main body 41 of the second container. The embodiment of FIG. 2 shows a state in which unevenness is formed so as to correspond to four accommodating portions 44 including two elongated accommodating portions 44 and two shorter accommodating portions 44 . A flange portion 43 is formed on the outer peripheral portion 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. Thus, the second container 40 is supported with its bottom surface floating.

As shown in FIG. 2 below the right side of the lid 42 of the second container, a knob portion 45 is formed so as to protrude from the flange portion 43 to the outer periphery. In the embodiment, the knob portion 45 is knurled so that it can be easily picked. Since the lid 42 of the second container is attached to the main body 41 of the second container in such a manner that it is press-fitted so that the juice and flavor of the ingredients in the storage portion 44 do not easily leak out, the knob portion 45 makes it easy to remove the lid 42 of the second container. It is something to do. Further, 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 40 which is only covered with the main body 31 of the first container can be opened. It also serves to keep the lid 32 of the container from floating.

Furthermore, the knob portion 33 of the first container 30 and the knob portion 45 of the second container 40 are oriented in the same direction when the first container 30 and the second container 40 are correctly arranged in a predetermined orientation. Since it is provided on the side, it also serves to prevent the direction of the container to be stored from being mistaken by arranging the direction of both knobs (33, 45) in the same direction. In the embodiment shown in FIG. 2, the correct arrangement is to store both knobs (33, 45) on the right side.
