Description

The present invention provides a small container for food that can close the gaps between the small containers when arranged in an outer box and can prevent the small containers from rising due to impact during transportation, and the same. It relates to a food container set.

As a food container used for bento and osechi, the outer box is integrated with the outer box inside, or a separate partition is provided inside the outer box. A container for storing vegetables and the like is generally known. Conventionally, it is also known that each food is placed in a subdivided container and then packed in an outer box (see Patent Documents 1 to 4, for example).

However, in the structure in which a recess is formed in the outer box as described in Patent Documents 1 and 2, and the subdivision container is arranged according to the position and shape of this recess, the shape of the subdivision container is limited by the recess. It will be done. Moreover, since an outer box with a concave portion is required, an existing jubako cannot be used as it is, and the manufacturing of the outer box with a complicated shape tends to increase the product cost.

In the food containers described in Patent Documents 3 and 4, although it is not necessary to form a recess in the outer box, the structure is such that a plurality of subdivided containers are arranged in the outer box. In addition, there is a problem that the small container rises due to impact, etc., and the small container tilts greatly, causing the food in the container to spill into the adjacent small container, or the sauce of the food to flow into the adjacent small container. easy.

In addition, in the above-described conventional technology, since gaps are likely to occur between the subdivided containers, the bottom surface of the outer box is exposed through the gaps, and the appearance of the boxed lunch or the like is likely to be spoiled (for example, when golden food containers are arranged, the outer box is likely to be damaged). (e.g., the bottom surface of the product is exposed through the gap and the sense of luxury is lost). In addition, gaps between sub-containers tend to cause the problem that moisture, sauce, etc. drips from the gaps onto the bottom surface of the outer box.

An object of the present invention is to solve the above-mentioned problems of the prior art. To provide a subdivided container for food and a food container set using the subdivided container capable of solving the problem of dripping and preventing the subdivided container from floating due to impact or the like during transportation.

As a means for solving the above problems, the present inventor has proposed that the subdivided container main body 1 has a polygonal bottom portion 11 and a trunk portion 12 that tapers outward from the outer periphery of the bottom portion 11 and spreads upward. and, on the opening side of the body portion 12, an upper portion 12b having a steeper slope than the lower portion 12a on the bottom portion 11 side is formed as a receptacle on the opening side, and the small container main body 1, a configuration is adopted in which the rim 12c of the upper end of the trunk portion 12 is folded downward to form a hanging portion 13 and a flange portion 14 protruding outward from the lower end of the hanging portion 13 (see FIG. 1). .

Further, in the present invention, the drooping portion 13 is formed in a tapered shape that widens outward, and the slope of the drooping portion 13 is made smaller than the slope of the body portion 12, so that the small container body 1 It is possible to suppress the deformation of the drooping portion 13 while suppressing the size in plan view.

In the present invention, by forming the protrusion width of the flange portion 14 within the range of 1.0 mm to 3.0 mm, the flange portions 14 can be easily overlapped while suppressing the size of the subdivided container main body 1 in a plan view. can.

In addition, in the present invention, at least the upper part 12b and the mouth edge 12c of the trunk 12 are given a glossy color or pattern, so that the flange 14 can be made inconspicuous.

In the present invention, a food container set can be constructed by laying the sub-container main bodies 1 of the above sub-containers for food in the outer box 2. In this case, the adjacent sub-container main bodies 1, 1 The flange portions 14 and 14 can be arranged in a vertically overlapping state.

In the present invention, in a small food container having a polygonal bottom portion, a hanging portion is formed by folding the rim portion of the upper end of the body portion downward, and a flange portion protruding outward from the lower end of the hanging portion is formed. By doing so, when the sub-containers are packed in the outer box, the flange portions of the adjacent sub-containers overlap each other, so that the gap between the containers can be closed.

As a result, it is possible to solve the problem that the bottom surface of the outer box is exposed through the gaps between the sub-containers and the appearance is spoiled, and the problem that the sagging or the like drips from the gaps between the sub-containers to the bottom surface of the outer box. In addition, since the flange portions overlap each other, it is possible to prevent the small portion container with the flange portion arranged on the lower side from being lifted up.

Further, in the present invention, the body of the small container is tapered upward from the outer periphery of the bottom portion, and the body has a greater gradient than the lower portion on the bottom side. Since the upper part is formed as a receptacle on the opening side, the visible area of the receptacle of the subdivided container when viewed from the upper side becomes large, and the flange part having a relatively small visible area can be made inconspicuous.

"First Embodiment"
A first embodiment of the present invention will be described with reference to FIGS. 1 to 5. FIG. In the figure, the item indicated by reference numeral 1 is the sub-portion container main body, and the item indicated by reference numeral 2 is the outer box. A food container set is designated by symbol S.

"food container set"
[1] Basic configuration In this embodiment, as shown in FIG. The food container set S is constructed by laying it all over. As shown in FIGS. 2 to 4, the two types of small container bodies 1 and 1' have a square or rectangular bottom portion 11 and a tapered shape extending upward from the outer circumference of the bottom portion 11. In this body portion 12, an upper portion 12b having a steeper slope than a lower portion 12a on the bottom portion 11 side is formed as a receptacle on the opening side.

Furthermore, as shown in FIG. 5(a), the rim 12c of the upper end of the body 12 is folded downward to form a hanging portion 13 in the sub-container bodies 1 and 1'. When the flange portion 14 projecting outward from the lower end is formed and the outer box 2 is laid out, the flange portions 14, 14 of the adjoining sub-container bodies 1, 1' meet each other as shown in Fig. 5(b). They are stacked vertically. This not only prevents deformation and floating of the sub-container bodies 1 and 1', but also hides the gaps between the sub-container bodies 1 and 1'.

[2] About the small container body
[2-1] Materials Next, each component of the food container set will be described. First, with regard to the material of the small container bodies 1 and 1', polypropylene is used in this embodiment, but other synthetic resin materials can also be used. PET resin), polyethylene, polyacetal, etc. can also be used. As the material for the small container body 1, it is preferable to use a thermoplastic resin that can be vacuum-formed, but a thermosetting resin, a metal material, or the like can also be used.

In the present embodiment, the small container bodies 1 and 1' are produced by vacuum forming the thermoplastic resin film, but a method such as sheet forming can also be adopted. Also, the thickness of the thermoplastic resin film is preferably in the range of 0.5 mm to 2.0 mm, which is suitable for vacuum forming.

In the present embodiment, a thermoplastic resin film colored in glossy gold (yellow + metallic luster) is used as the material of the small container bodies 1 and 1' so that the gaps between the containers are inconspicuous. However, those colored in black, red, white, etc. (opaque colors) can also be adopted, and other colors having metallic luster such as silver (white + metallic luster) can also be used. Moreover, it is not necessary to use a single color, and for example, patterns of a plurality of colors can be formed on the bottom portion 11 and the body portion 12 of the small container bodies 1 and 1'. Also, only the upper portion 12b and the lip portion 12c of the body portion 12 may be given a glossy color or pattern so that the gaps between the containers are inconspicuous.

[2-2] Shape of the bottom With regard to the shape of the bottom 11 of the sub-container bodies 1 and 1', in this embodiment, the bottom 11 is square or rectangular as shown in FIGS. 3(a) and 3(b). However, other polygonal shapes such as triangles, pentagons, trapezoids or parallelograms can be used depending on the type of food to be contained in the container. In this embodiment, as shown in FIGS. 3(a)(b) and 4(a)(b), the bottom portion 12 is formed with an upwardly protruding raised portion at the center portion thereof so that the bottom portion when food is put therein. 12 deformation is suppressed. In addition, on the bottom part 12, characters such as a material name, a recycling mark, a company name, a product number, etc., can be formed by unevenness.

[2-3] Body shape The shape of the body 12 of the small container bodies 1 and 1' is shown in Figs. 2(a)(b) and 4(a)(b) in this embodiment. As shown, the lower portion 12a is formed so that the gradient α is within the range of 5 degrees to 20 degrees, and the upper portion 12b is formed so that the gradient β is within the range of 20 degrees to 50 degrees. In addition, the vertical ratio of the lower portion 12a and the upper portion 12b in the total height of the body portion 12 is set within the range of 6:1 to 2:1. As a result, the upper portion 12b of the body portion 12 can be used as a socket for the opening portion while securing the volume of the sub-portion container main bodies 1 and 1'.

[2-4] Shape of drooping portion The shape of the drooping portion 13 of the sub-container main bodies 1 and 1' is shown in FIGS. 2(a)(b) and 4(a)(b) in this embodiment. Thus, even when the drooping portion 13 is formed in a tapered shape that widens outward and an inward force is applied to the drooping portion 13, deformation is suppressed. As for the tapered shape of the drooping portion 13, as shown in FIG. The visual area) is kept from becoming too large. Further, in this embodiment, the drooping portion 13 is formed within the range of the vertical height of the upper portion 12a of the trunk portion 12. As shown in FIG.

[2-5] Shape of flange part In this embodiment, the shape of the flange part 14 of the sub-container main bodies 1 and 1' is shown in Figs. As shown in 5(a), the lower end of the drooping portion 13 protrudes outward in the horizontal direction (right lateral direction). Further, in this embodiment, the width of the flange portion 14 is formed within the range of 1.0 mm to 3.0 mm so that the size (area in plan view) of the small container main bodies 1 and 1' does not become too large. ing. If the protrusion width of the flange portion 14 is less than 1.0 mm, the overlapping area of the adjacent sub-portion container main bodies 1 and 1' becomes too small, and gaps between the containers and floating tend to occur.

5(b), the flange portions 14 are vertically overlapped with each other when the sub-portion container bodies 1 and 1' are spread over the outer box 2. The flange portion 14 comes into contact with the drooping portion 13 of the adjacent sub-container main body 1'. Therefore, when food is put into the sub-container main bodies 1 and 1', the upper flange portion 14 presses the lower flange portion 14 down. When the food container set S containing food is carried, lateral force is applied due to vibration or inclination, and the adjacent sub-portion container bodies 1 and 1' are pressed against each other. , the pressing force is absorbed by the drooping portion 13, and deformation of the sub-portion container main body 1.1 can be prevented.

In addition, as shown in FIG. 5(b), since the flange portions 14 and 14 are overlapped with each other, there is no gap between the sub-portion container bodies 1 and 1', so when the food container set S is viewed from above, The bottom surface of the outer box 2 is not visible through the gap between the sub-container bodies 1 and 1', and the appearance of the food container set S can be improved. In addition, since there is no gap between the small container bodies 1 and 1', it is possible to prevent the problem of food falling on the bottom surface of the outer box 2 or liquid leaking.

[2-6] Modified Example with Partitions In this embodiment, a shape is adopted in which partitions are not provided in the sub-container main bodies 1 and 1'. Partitions in the length direction, width direction, or diagonal direction can be provided integrally or separately (not shown). It can be housed in a container set S.

[2-7] Modification example with lid member In this embodiment, the sub-container main bodies 1 and 1' are shaped without lids, but the lid members are provided separately or integrally with the sub-container main bodies 1 and 1'. (not shown). You can prevent the liquid from leaking.

[2-8] Modified example with cradles In the present embodiment, the subdivision container main bodies 1 and 1' are all formed to have the same height. shallow bottom) can also be used. In this case, a stand for mounting the small container body 1 may be provided separately or integrally so as to fit the upper surface of the small container body 1 having a large height (not shown).

[3] About the outer box
[3-1] Material and shape of the outer box As for the material of the outer box 2, in this embodiment, a box made of a plastic material is used. A wooden material (paulownia box) or a metal material other than the plastic material can also be used. As for the shape of the outer box 2, the form of folding box or multi-tiered box can be appropriately adopted according to the use of the food container set S (New Year's dishes, cherry-blossom viewing lunches, station lunches, etc.). The shape of the outer casing 2 in a plan view is preferably polygonal, and particularly preferably quadrangular or octagonal (eg, octagonal double).

[4] Combination of small containers
[4-1] Combination of Square and Rectangular Containers In this embodiment, as shown in FIG. The number, size, and arrangement of these can be changed as appropriate. For example, it is also possible to use a combination of a square-shaped sub-container main body and two kinds of rectangular sub-container main bodies of different lengths (not shown).

[4-2] Combination of small containers of the same shape Also, only small container bodies 1 of the same shape (for example, square-shaped small container bodies 1) are used, and these are spread over the outer box 2. (not shown). Alternatively, for example, triangular or rectangular sub-container bodies alone may be used. At that time, it is also possible to use a combination of small container bodies having the same shape but different colors and materials.

[4-3] Combination of square and triangular subcontainers It is also possible to use a combination of a square subcontainer main body and a triangular subcontainer main body. It is also possible to replace part of the sub-container bodies 1, 1' with two triangular sub-container bodies (not shown). Also, in the octagonal outer box 2, a triangular sub-container main body can be used on the outer peripheral portion.

[4-4] Combination using trapezoidal subcontainers Alternatively, trapezoidal subcontainers can be partially used. Molded aliquots can be used (not shown). In particular, trapezoidal or rectangular subdivided container bodies can be suitably used as relatively large containers for containing rice, main dishes, and the like. In addition, pentagonal, hexagonal, octagonal, etc. subdivided containers can also be used in combination, if necessary.
