[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a disposable lunch box system, which is used as a lunch box lunch or a kaiseki lunch box, and is composed of an outer box for outer use, a plurality of inner boxes for storing foods, a lid, and the like.

[0002]

[Prior art]

 Conventionally, lunch boxes used as lunch boxes and multi-course lunches of this type form a partition wall by, for example, injection molding a foamed synthetic resin material in order to separately store multiple ingredients in the outer case. In this way, a single inner box for storing different foodstuffs, which is formed by partitioning a plurality of storage sections for different foodstuffs, is stored in the outer box for exterior use, or a cutout provided with a plurality of band-shaped partition plates. In this case, the frame material, which is divided vertically and horizontally or obliquely through the outer casing, is stored in the outer casing, so that the outer casing is divided into a plurality of compartments and stored.

[0003]

[Problems to be solved by the invention]

 However, in such a conventional lunch box, a single storage box for each foodstuff is used which is formed by forming a partition wall by injection molding of a foamed synthetic resin material to form a plurality of storage sections for each foodstuff. In this case, it is necessary to change the arrangement pattern of the foodstuffs stored in the outer case because the partition arrangement pattern of the foodstuff-specific storage unit itself is already determined as one pattern by the injection molding die. In order to form partition walls with different shape patterns, separate molds etc. are used for injection molding of synthetic resin materials, etc. A box must be formed, which is too laborious and costly to manufacture. On the other hand, in the case of storing a frame material, which is formed by intersecting a plurality of strip-shaped partition plates in a vertical or horizontal or oblique manner, in an outer case, it is necessary to change the partition arrangement pattern of the storage section for each foodstuff. Changes the position of the breaks in the partition plate to change the crossing state, but this is also a very cumbersome operation in terms of manufacturing and in combination, and has problems such as high costs. .

Accordingly, the present invention has been made in view of the above-described circumstances that existed in the past, and by appropriately selecting and combining a plurality of food storage inner boxes in various forms. , The arrangement pattern of the ingredients stored in the outer box can be freely changed, and it is possible to realize an array pattern that gives a fresh impression to the eater, regardless of whether it is for lunch or banquet, Moreover, an object of the present invention is to provide a disposable lunch box system capable of reducing labor and cost in manufacturing.

[Embodiment of the invention]

 An embodiment of the present invention will be described below with reference to the drawings. Reference numeral P shown in the figure is a lunch box used as a lunch box lunch, a Kaiseki lunch, etc. which constitutes a lunch box system according to the present invention. . As shown in FIG. 1, the lunch box P has an outer case 1 of a square box shape forming an outer case, and a square, rectangle, triangle or the like having different sizes in the outer case 1, respectively. Based on the division arrangement pattern by the combination of the above, it is arranged and stored without waste so that there is no empty space, and a plurality of square boxes, rectangular boxes, triangle boxes, etc. for storing a plurality of foodstuffs Q individually in itself. It comprises a box 2 for storing foodstuffs separately, and a lid 3 in the form of, for example, a square box for covering the outer box 1 for exterior use. As shown in FIGS. 6 and 7, the bottom of the storage box for each foodstuff 2 has a temperature within a range that does not lower the taste of the foodstuff Q stored in the storage box for foodstuff 2 itself. In some cases, a heat insulating / cooling material 4 may be provided so as to be always held.

As shown in FIG. 4 and FIG. 5, each of the outer case 1, the middle box 2 for storing foods, and the lid 3 has a predetermined thickness with a waterproof treatment R such as a vinyl coating on the surface. In other words, the paper material is made of a paper material which retains its shape when various foodstuffs Q are stored therein and has such a rigidity that it is not easily broken down. As shown in FIGS. 6 and 7, a hole 5 for supplying / distributing air to / from the heat insulating / cooling material 4 is formed in the lower part of the side wall surface of the food storing middle box 2.

In this embodiment, the outer box 1 having a square box shape is employed. However, the present invention is not limited to this. For example, the outer box 1 having a rectangular box shape or a triangular box shape may be employed. good. In addition, although the outer case 1 is used as one stage, the outer case 1 may be used by stacking it in two or more stages, such as a heavy box, or a plurality of the outer case 1 itself may be arranged in parallel. You may do it. Further, as the material of the outer case 1 for outer packaging, the inner box 2 for storing foods, and the lid 3, for example, synthetic resin materials such as plastics, light metal materials such as aluminum, wood, etc. may be used. However, it does not matter. In addition, the exterior outer box 1, the food storage inner box 2, the lid 3, and the like are given a predetermined color such as red or black on the surface or the like, or have an appropriate pattern such as a corrugated pattern. It is given a Shochiku plum pattern or the like, and is further considered to have a lacquer-like, wave-like, white-like or fruit-like appearance.

When the storage box 2 for each foodstuff is developed in a square box shape, for example, as shown in FIG. 4, for example, a square bottom portion formed based on the pattern components of the partition arrangement pattern, as shown in FIG. A substantially trapezoidal middle fold wall portion 16 is extended around a valley fold line portion 12 around a valley fold line portion 11, and a mountain fold line portion 13 is formed at a corner of the bottom portion 11 and a valley fold line portion sandwiching both sides thereof. 14, a side surface of each of the center fold wall portions 16 is connected to each other via a V-shaped center fold portion 15 formed in a substantially triangular shape. A substantially trapezoidal outer folding wall portion 19, which is slightly longer than the center folding wall portion 16, extends on the outer edge of the center folding wall portion 16 via two mountain fold lines 17, 18 parallel to each other. A tongue-shaped insertion piece 20 is formed at both side ends of one outer folding wall portion 19, and a center folding wall portion is formed at both side ends of the other outer folding wall portion 19 via a valley fold line portion 21. A substantially triangular ear portion 22 is formed between the outer portion 16 and the outer fold wall portion 19, and a slit-like insertion hole 23 is formed in the valley fold portion 21 for inserting and inserting the insertion piece 20. I have.

When the storage box 2 for each foodstuff has a triangular box shape, as shown in FIG. 5, a substantially trapezoidal shape is formed around a triangular bottom surface portion 11 through a valley fold line portion 12. A folded wall portion 16 is extended, and a V-shaped center-fold portion 15 formed in a substantially triangular shape by a mountain fold line portion 13 and a valley fold line portion 14 sandwiching both sides of the mountain fold line portion 13 at the triangular vertex of the bottom portion 11 is formed. The side portions of each of the half-folded wall portions 16 are connected to each other through the intermediary. A substantially trapezoidal outer folding wall portion 19, which is slightly longer than the center folding wall portion 16, is extended from the outer edge of the center folding wall portion 16 through two mountain fold lines 17, 18 parallel to each other. A tongue-shaped insertion piece 20 is formed at both end portions of one outer folding wall portion 19, and a middle folding wall portion is formed at both end portions of one outer folding wall portion 19 via a valley fold portion 21. A substantially triangular lug 22 is formed between the portion 16 and the outer fold wall portion 19, and a slit-like insertion hole 23 is formed in the valley fold 21. Further, insertion pieces 20 for insertion into the insertion holes 23 are formed on both side ends of the other outer folding wall 19. Further, at one end of the other outer folded wall portion 19, a substantially triangular ear portion 22 sandwiched between the center folded wall portion 16 and the outer folded wall portion 19 via the valley folded portion 21 is formed. In addition, a slit-shaped insertion hole 23 is formed in the valley fold line portion 21, and an insertion piece 20 for insertion into the insertion hole 23 is formed in the other end of the outer folding wall surface portion 19.

When assembling the square box-shaped and triangular box-shaped intermediate boxes 2 for storing food, the center-folded wall portion 16 is bent inward from the bottom portion 11 through the valley fold line portion 12. At this time, the mountain fold line portion 13 of the V-shaped center fold portion 15 is mountain-folded, and at the same time, the valley fold line portions 14 on both sides are valley-folded, thereby bending the V-shaped center fold portion 15 itself into a V shape. By doing so, the side portions of each of the half-folded wall portions 16 are joined to each other. Then, the center fold wall portion 16 and the outer fold wall portion 19 are joined by folding the two mountain fold line portions 17 and 18 respectively. At this time, the ear portion 22 of the other outer folding wall portion 19 is previously sandwiched between the one middle folding wall portion 16 and the outer folding wall portion 19, and the insertion piece 20 is inserted into the insertion hole 23. If the outer folded wall portions 19 are connected to each other, the square box-shaped and triangular box-shaped storage boxes 2 for each food material can be easily formed.

Note that the outer case 1 itself is formed in the same shape as the developed shape of the middle box 2 for storing foodstuffs, but it is a matter of course that the present invention is not limited to this.

As shown in FIG. 8, a partition arrangement pattern of a plurality of storage boxes 2 for each foodstuff formed in the outer case 1 is a square plane having one vertical and horizontal scale with a fixed unit length as one scale. The combination of the partition arrangement patterns is formed on the basis of a square planar part composed of a total of 144 vertical 12 horizontal scales and 12 horizontal horizontal scales, each of which is a unit of part components. As shown in FIG. 9, this partitioning arrangement pattern sets a vertical unit of 4 graduations with a fixed unit length of, for example, 55 mm as one graduation as a reference size of each part, and sets a horizontal graduation of PK-1 ( 9A), PK-1.5 for three horizontal scale parts (see FIG. 9B), PK-2.5 for five horizontal scale parts (see FIG. 9C), and 6 horizontal. The parts of the scale are referred to as PK-3 (see Fig. 9 (d)), the parts with eight horizontal scales as PK-4 (see Fig. 9 (e)), and the parts with four horizontal scales as PK-4 (see Fig. 9 (e)). A part formed by dividing the area of a square plane called PK-2 (refer to FIG. 9 (f)) and a square plane which is a part PK-2 having four vertical and horizontal scales by a diagonal line into PS-1 (see FIG. 9 (f)). (See (g)). The area of the right-angled isosceles triangular plane and the rectangular plane which is the part PK-4 of 4 vertical scales and 8 horizontal scales is set to 1 The parts formed by dividing into 1: 2 into three parts are PS-1 and PS-2 (see FIG. 9 (h)), and these parts are variously designated as large and small right-angled isosceles triangular planes as pattern components. By combining the above, about 1000 or more partition arrangement patterns are formed.

Next, a description will be given of an example of a combined use of the partition arrangement patterns of the food storing inner box 2 in the embodiment configured as described above. In addition, as shown below, the display of 95-75, 110-55, 110-40, etc., indicating the vertical and horizontal sizes of the outer case 1 indicate numerical values obtained by reducing the actual size of the vertical and horizontal sizes to about 1/3. For example, the display of 110-55 indicates that the vertical length is about 330 mm and the horizontal length is about 165 mm. However, such numeral display is only for convenience and the display method is not limited to this, and by using such a display method, the size of the lunch box manufacturer and the lunch box distributor can be reduced between the lunch box manufacturer and the lunch box seller. This has the advantage that it is easy to understand the general idea, and it is not necessary to use the display of numerically large items, which simplifies it.

Further, when the display of the vertical and horizontal sizes of each part is 110-55, PK-1 is used, when 110-82.5 is displayed, PK-1.5 is used, and when 110-110 is used, PK-2 is used, 137. The case of 5-110 is PK-2.5, the case of 165-110 is (PK-3) [(PS-1) × 2 + (PS-1)], and the case of 220-110 is (PK-4). [(PS-2) + (PS-1) × 2], the case of 110-55.5 is referred to as PS-1, the case of 220-110 is referred to as PS-2, etc. (for example, FIG. This is explained below.

PK-3 is arranged (see FIG. 2B). When the display of the vertical and horizontal sizes of the outer case 1 is 75-75, the four parts PK-2 of the middle box 2 for storing foodstuffs are arranged in two horizontal rows, and the part PK-2 is located below and adjacent thereto. Arrange them in two horizontal rows (see Fig. 2 (c)). If the display of the vertical and horizontal sizes of the outer case 1 is 95-75, the parts PK-2 are arranged on both sides of the intermediate box 2 for foodstuffs so that the parts PK-1 are sandwiched between them. The part PK-3 and the part PK-2 are arranged side by side (see FIG. 2D). When the display of the vertical and horizontal size of the outer case 1 is 110-65, the three parts PK-1.5 of the middle box 2 for each food are arranged in three rows, and the part PK is located below the part PK-1.5. -3, parts PK-1 and PK-2 are arranged side by side in three rows (see FIG. 2 (e)).

In addition, as shown in FIG. 3, when the display of the length and width of the outer case 1 is 75-40, the parts PK-3 and PK-1 of the middle box 2 for storing foodstuffs are not included. Are stored in two horizontal rows (see FIG. 3A). When the display of the vertical and horizontal sizes of the outer case 1 is 110-40, the parts PK-2.5, PK-1.5, and PK-2 of the middle box 2 for storing foods are each displayed in the horizontal direction. They are arranged in a row (see FIG. 3B). If the vertical and horizontal size of the outer case 1 is 110-75, the three parts PS-1, PS-2, and PS-1 of the food storage box 2 are arranged in a rectangular shape, Next, PK-2 is arranged next to, and the parts PK-2 are arranged in three horizontal rows below this (see FIG. 3C). When the display of the vertical and horizontal size of the outer case 1 is 110-110, the two parts PK-4 and PK-2 of the middle box 2 for foodstuffs are arranged in two horizontal rows, and below this, Parts PK-2 are arranged on both sides so as to sandwich the two parts PK-1 arranged side by side, and two parts PK-3 arranged in two horizontal rows are arranged below the parts PK-2 (Fig. 3 (d)). When the display of the vertical and horizontal sizes of the outer case 1 is 75-75, the two parts PK-2 of the middle box 2 for storing foods are arranged in two horizontal rows, and the two parts PK are located below this. -2 are arranged in two horizontal rows (see FIG. 3E).

Further, as shown in FIG. 11, a state in which PS-1 and PS-1 are arranged on the right side of the two PK-1s arranged in parallel (see FIG. 11 (q)). The PS-1 / PS-1 is arranged in a different direction on the right side of the PK-1 (see FIG. 11 (r)). The PS-1 / PS- is located on the left side of the two aligned PK-1s. 1 (see FIG. 11 (s)), PS-1 and PS-1 arranged on the left side of two parallel PK-1s (see FIG. 11 (t)) A state where two PK-1s arranged side by side vertically are arranged on the right side of the two PK-1s arranged in parallel (see FIG. 11 (u)). A state in which two PK-1s arranged side by side vertically on the left side are arranged (see FIG. 11 (v)), and a state of a combination of PS-1, PS-2 and PS-1 (FIG. 11) (See (w)), the state of the combination of PS-1, PS-2, and PS-1 changed in the up and down direction (see FIG. 11 (x)). There is a state of parallel arrangement (see FIGS. 11 (y), (z), (yy), (zz)), and these are totaled to form a 28-partition arrangement pattern.

In the case where the display of the vertical and horizontal sizes of the outer case 1 is 75-75, the partition arrangement pattern when the vertical and horizontal sizes are 75-40 is used by using two steps (28 × 28 + 28). 2 = 406 partition arrangement patterns are possible, and 406 × 2 = 812 patterns can be used by further reversing the upper and lower rows. If four parts PS-2 are used, 813 types of parts can be used.

In the case where the display of the vertical and horizontal sizes of the outer case 1 is 110-40, as shown in FIGS. 12A to 12E, the partition arrangement pattern when the vertical and horizontal sizes are 75 to 40 is shown. By adding the pattern constituent elements of the two PK-1, one PK-2, and two PS-1 parts to the left and right, 28 partition arrangement patterns in the case of 75-40 can be obtained. The number of turns is 10 times, 28 × 10 patterns in a row, and a total of 281 patterns can be used by adding two PK-3 parts.

When the display of the vertical and horizontal size of the outer case 1 is 110-75, the partition arrangement pattern when the vertical and horizontal size is 110-40 is used by using two steps ((281 × 281 + 281)). ÷ 2 = 39621 kinds of partition arrangement patterns are possible, and 39621 × 2 = 79242 kinds of use are possible by using the upper and lower sections in reverse.

In the case where the display of the vertical and horizontal sizes of the outer case 1 is 110-110, there are 79242 types of partitioning arrangement patterns when the vertical and horizontal sizes are 110-75, and 281 when the vertical and horizontal sizes are 110-40. It is possible to use a plurality of partition arrangement patterns in the upper, middle, and lower tiers, and at this time, a total of 79,242 × 281 × 3 = 66801006 combinations are possible.

In the case where N parts are used, the basic arithmetic expressions of one or two stages are (N + 1) × N ÷ 2 according to a combination formula for selecting two sets from N parts. For example, when five parts are used, (5 × 5 + 5) ÷ 2 = 15, and a total of 15 arrangement patterns are possible. Further, the basic arithmetic expression of two to three stages is (total pattern of two stages) × (pattern of one stage) = (total pattern of three stages). At this time, the total pattern of two stages is used in the upper stage and the lower stage is used, and the total pattern of the three stages is obtained by multiplying the total pattern of the two stages by one stage pattern to be three times the upper, middle, and lower stages.

In the case where the display of the vertical and horizontal sizes of the outer case 1 is 75-55, in the vertical use, it can be used in two stages of 11 parts as shown in FIGS. 13 (a) to 13 (k). At this time, (11 × 11 + 11) ÷ 2 = 66 ways can be used, and 66 × 2 = 132 ways can be used by further reversing the upper and lower stages. On the other hand, in the horizontal use, by using two PK-1s horizontally in 28 patterns when the display of the vertical and horizontal sizes of the outer case 1 is 75-40, the outer case 1 can be used in 28 ways.

When the display of the vertical and horizontal size of the outer case 1 is 110-65, it can be used in horizontal use by attaching three PK-1.5 to the 281 pattern when the vertical and horizontal size is 110-40. 562 can be used by using the upper and lower tiers. On the other hand, in the vertical use, PK-1.5 can be used with five parts as shown in FIGS. 12 (a) to 12 (e). For example, it is possible to use 10 patterns on the left and right in one stage, (10 × 10 + 10) ÷ 2 = 55 in two stages, and 550 in 55 × 10 in three stages.

When the display of the vertical and horizontal sizes of the outer case 1 is 95-75, the parts are PK-1, PK-1.5, PK-2... In horizontal use as shown in FIGS. 5, PK-3, PK-4, PK-2, PS-1, and PS-2 by appropriately combining the eight pattern components, a total of 49 combined patterns are used in two stages, so that ( (49 × 49 + 49) ÷ 2 = 1225 usages are possible.

[Effect of the invention]

 Since the present invention is configured as described above, a variety of combinations of a plurality of storage boxes 2 for various foodstuffs in various forms are selected and stored in the outer box 1 for outer packaging. The arrangement pattern of the ingredients Q stored in the outer box 1 can be freely changed, and the labor and cost for manufacturing can be reduced. You can select a container mode and form that matches Q.

That is to say, this is because the present invention has various combinations such that the outer case 1 forming the outer case of the lunch box P and the plurality of ingredients Q are individually stored and arranged in the outer case 1. This is because it has a plurality of storage boxes 2 for each foodstuff arranged based on the combined partition arrangement pattern, and a lid 3 for covering the outer packaging box 1, thereby saving labor and cost. In addition, the arrangement pattern of the food material Q in the outer case 1 can be easily and freely changed.

Since the exterior outer box 1 has a plurality of itself stacked on top of each other or arranged side by side, the degree of freedom in the combination of the arrangement patterns of the food materials Q stored in the exterior outer box 1 is greatly increased. Can be increased.

The section arrangement pattern is a square box-shaped, rectangular box-shaped, and triangle box-shaped foodstuff of different sizes to be stored and arranged inside the outer case 1 such as a square box, a rectangular box, and a triangle box. Since the configuration is based on the combination of the separate storage inner boxes 2, the combination of the square storage box, the rectangular box shape, and the triangular box-shaped storage box 2 for different foodstuffs allows, for example, more than 1000 combinations according to the needs of the user. It is possible to realize the food arrangement pattern.

The partition arrangement pattern has a rectangular plane, a square plane, and a large and small right-angled isosceles triangular plane with four vertical graduations each having a fixed unit length as one graduation as a basis of each part. It is possible to freely change the pattern setting for the vertical use and the horizontal use of the food storage middle box 2 corresponding to the outer case 1 having different sizes.

The outer case 1 for outer packaging and the inner box 2 for storing foods are mutually connected via a bottom portion 11 formed based on the pattern components of the partition arrangement pattern and a V-shaped center folded portion 15. The unfolded shape is formed by a center-folded wall portion 16 formed by connecting the portions, and an outer-folded wall portion 19 that allows the side portions to be joined to each other via the insertion piece 20 and the insertion hole 23. Therefore, a space layer is formed on the side wall by the center-folding wall portion 16 and the outer-folding wall portion 19, and the outer box 1 having a square box shape, a rectangular box shape, and a triangular box shape having heat insulation and durability. In addition, it is possible to easily form the middle box 2 for storing each food.

The outer box 1 for exterior and the inner box 2 for storing foods are made of a paper material having a predetermined thickness and subjected to a waterproof treatment R on the surface, so that leakage of the juice Q of the foods Q can be prevented, In addition, costs can be reduced. Moreover, since it is made of paper, it can be easily incinerated, the problem of trash disposal can be solved, and an environmentally friendly disposable lunch box P can be realized.

At the bottom of the storage box 2 for each foodstuff, a heat retention / cooling material 4 for keeping the temperature of the foodstuff Q stored in the storage box 2 for each foodstuff itself within a range that does not degrade the taste is provided. Therefore, it is possible to provide a lunch box P that does not lower the taste of the foodstuff Q.
