[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a container which is a molding of a generally disposable thermoplastic resin or paper material of a lunch box or a merchandise container sold at a supermarket, a grocery store or a packaging supply store.

[0002]

2. Description of the Related Art In many cases, a lunch box made of a resin molded product on the market is often provided with separate recesses in a single box, in which rice and side dishes are stored, respectively. Alternatively, a rice container and a side dish container having substantially the same size are separated, and the side dish container is placed in a compartment provided therein. Alternatively, rice is put in a large container without putting it in a container that can be divided into small pieces. Further, as a stacking container, there is Japanese Utility Model Publication No. 4-49075 previously proposed by the applicant.

[0003]

[Problem to be solved by the invention] In the first container, rice and side dishes are all contained in one box, and pickles,
Since it is not preferable to warm the vinegar and the like, if it is desired to warm a part of the vinegar in a microwave oven, it is necessary to transfer only the vinegar to another container, which is troublesome. There is no problem in warming all the side dishes that are separated from the second rice and side dishes, but trying to heat a part of them is as troublesome as in the first. In addition, when rice and side dishes are piled up, there is a problem that if they are not tied up, the contents of the misalignment will be shifted during carrying.

[0004] Furthermore, the third rice and side dishes are put in separate containers, and the side dishes placed separately in small containers are separated and inconvenient to carry. There is a problem that an extra container is required because the entire container is stored, and the container is bulky because the container is stored in the container. 4-4
No. 9075 is capable of stacking the same shape detachably, but it cannot separate side dishes and cannot mix and combine various sizes and shapes arbitrarily. There's a problem.

[0005] The present invention has been made in view of such problems of the prior art, and the purpose of the present invention is to be able to arbitrarily select and combine them according to the contents, and to make only the side dishes to be warmed. An object of the present invention is to provide a container suitable for a lunch box that can be easily separated and does not collapse when being carried. Further, it is an object of the present invention to provide a container suitable for a lunch box that can stably support cups and side dishes even in unstable places when eating outdoors.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. The container 1 in which a thermoplastic resin sheet or a film or a sheet made of paper is vacuum- or pressure-formed is a large-sized container mainly for rice, and has an inverted tapered fitting convex that extends downward in an oval shape on a drafted bottom surface. Parts 1a, 1a, 1
b and 1b are formed. 1a and 1a; 1b and 1b have the same shape, and are arranged at the four corners of the bottom surface in parallel in the same direction. 1a and 1b may have the same shape or may have different sizes and shapes. In the embodiment, 1a
And 1b have the same width but differ only in length. And container 1
The edge of the bent portion 1 is hooked outward as shown in FIG.
c is formed on the entire circumference, and its cylindrical portion serves as a fitting portion with the lid 2.

A lid 2 formed by integrally or separately forming a thermoplastic resin sheet or a film or a paper sheet with a container 1 by vacuum or compressed air is a fitting projection 1a, 1 at the bottom of the container 1.
1b, 1b are fitted with slightly larger, inversely tapered fitting recesses 2a, 2a; 2b, 2b, respectively, at positions corresponding to the projections 1a, 1a; 1a, 1b. . A bent portion 2c as shown in the figure is formed all around the outer periphery of the lid 2, and an engagement recess 2d which can be fitted to the bent portion 1c of the container and inflates inward at the end of the bent portion 2c. It is formed on the entire circumference or several places around the circumference and engages with the end of the bent portion 1c to ensure the fitting connection between the container 1 and the lid 2.

The fitting portions 1a, 1b and the fitting recesses 2a,
As the shape of 2b, for example, Japanese Utility Model Publication No. 4-49075 can be adopted. Furthermore, the shape of the fitting portion between the rim of the container 1 and the lid 2 can be, for example, that of Japanese Utility Model Publication No. 4-41087 or Japanese Utility Model Publication No. 4-49075.
As shown in FIG. 3, if the container 1 is formed as a flat surface without forming the fitting projections 1a and 1b on the bottom surface, it is convenient when used for the lowermost layer of the stack.

Also, fitting projections 1a, 1a; 1b, 1 on the bottom surface.
When b is formed about 1 mm inward from the outer circumference 1e of the bottom as shown in FIG. 2 and the end 1d having a large diameter of the reverse tapered end face is flush with or inward from the outer circumference 1e of the bottom, it is convenient to stack the containers 1. Is good. The container 1 with the lid 2 is configured such that the fitting projections 1a, 1a; 1b, 1b of the container 1 are
a, 2a; 2b, 2b can be stacked in multiple stages.

As shown in FIGS. 4 and 5, the medium-sized container 3 mainly serving as a side dish, which is placed on the fitting concave portion 2a of the lid 2, has the same depth as the container 1, the bent portion of the lip, and the like. However, the present invention is not limited to this. The volume is reduced and the number of the fitting protrusions is reduced, and the reverse tapered fitting protrusions 3a, 3 on the bottom surface are formed.
a is formed at the both ends in parallel with two having the same shape as the fitting projection 1a. These two fitting projections 3a, 3a
Are slightly similar to the fitting recesses 2a, 2a of the lid 2 and are formed slightly smaller.
Since it is formed at two positions corresponding to 2a, the fitting projections 3a, 3a of the container 3 can be fitted simultaneously to the fitting recesses 2a, 2a of the lid 2.

The cover 4 covering the container 3 has the same depth and bent portion as the cover 2 and is made smaller in accordance with the container 3, and the number of fitting recesses is the same as that of the container 3. Two mating concave portions are formed at positions corresponding to the fitting convex portions 3a, 3a of the container 3. The same container 3 with the lid 4 can be stacked in various types in the fitted state. Furthermore, the small container 5 mainly for side dishes is the same as the container 3 in the depth, the bent portion of the lip, etc., but is not limited to this. The volume is reduced and the fitting projection 5a is made one. In this case, an inversely tapered convex portion 5a is formed on the entire bottom surface.

The lid 6 covering the container 5 has the same depth and bent portion as the lid 4 and is formed with a single inverted tapered fitting concave portion 6a into which the fitting convex portion 5a is fitted. 4-490
It is the same as No. 75. Therefore, it goes without saying that the fitting concave portion 5a of the container 5 and the fitting convex portion 6a of the lid 6 are sequentially fitted and stacked. The bent portions of the lids 4 and 6 covered with the bent portions of the containers 3 and 5 are the same as those described in Japanese Patent Publication No. 4-41087.
Or No. 4-49075.

Further, as shown in FIG. 6, a medium-sized container 7 mainly serving as a side dish, which is placed on the fitting recesses 2b of the lid 2, is formed by making the long rectangular container 3 wide and substantially square. The two inverted tapered fitting projections 7b, 7b
The fitting recesses 2b, 2 of the lid 2 have the same shape as the fitting projections 1b, 1b.
b, is slightly smaller and has a lid 2
The lid 2 is formed at a position corresponding to the fitting recesses 2b when it is placed on the upper side.
The fitting protrusions 7b, 7b of the container 7 can be fitted to 2b.

The lid 8 covering the container 7 is also the same as the lid 4 in which the width of the lid 4 is widened and the length of the inversely tapered fitting recesses 4a, 4a is increased, and the fitting projections 7b, 7b. Further, although not shown, a small container with a side dish for the side dish to be placed on the lid 8 is one in which the container 5 and the lid 6 are elongated, and the fitting projection of the container is formed by the fitting recess 8 of the lid 8.
b, and the fitting recess of the lid corresponds to one of the fitting projections of the container.

That is, the former A series having the same single fitting portion and the latter B series having the same single fitting portion have different lengths of the single fitting portion and other shapes are the same.
The A-series container with a lid or the B-series container with a lid can be fitted in the stack by arbitrarily changing the stacking order or arbitrarily changing the combination. Food or goods can be freely placed in such various containers. A large container 1 with a lid 2 is shaped like an a, and a flat bottom of the container 1 with a lid 2 is called a.
The container A with the lid 4 in the A series is a square shape, the container 5 with the lid 6 is a C shape, the container 7 with a lid 8 in the B series is a D shape, and a small container placed on the D shape is an E shape.

Now, for example, rice, b, and d are boiled and tempura side dishes in the a and b shapes, and pickles are in the c shape.
Assume that you have packed the sauce in the shape of E. The combination can be arbitrarily performed as follows. For example, the first layer A 'and the second layer are each a combination of a B shape and a D shape. This combination is i '+
When displayed as (b, d), i '+ (c, ha, d) i' + (b, ho, e) + i '+ b + (b, d) + (c, c, e , E) and can be developed more freely.

Further, as the large container 11 mainly for rice, as shown in FIG. 7, inverted tapered L-shaped fitting projections 11a, 11a, serving also as legs at four corners of the bottom surface of a square container.
11a, 11a are formed, and a fitting projection 1 is formed on the upper surface of the lid 12.
4a, four quadrangular inverted tapered fitting concave portions 12a, 12a, 12b, 12b having completely different shapes are formed. In particular, each of the fitting concave portions 11a at the four corners can be fitted. It is located including the corner, and when the containers with lids are overlapped, they are connected by fitting at four corners.

These fitting recesses 12a and 12b can be fitted by forming fitting projections of medium and small containers mainly for side dishes placed thereon in the same manner as described above. In this case, several types of medium-sized and small-sized containers with lids are made in the same manner as described above. The fitting recess 12a of the lid 12
A medium and small container with a lid, A and B, with different shapes of 12b
By dividing into groups, they can be combined in the same manner as described above.

Although the fitting projection on the bottom surface is L-shaped, it is not limited to this, and it may be an inverted tapered cylinder, square cylinder, or the like. It is also possible to freely form the fitting projection. However, in the case of such partial fitting, fitting portions need to be present at least at three corners for positioning. Further, a boat-shaped mainly rice container 13 as shown in FIG. 8 has triangular inverted tapered fitting projections 13a, 13a, 13a, 13a formed at four corners of the bottom surface.

The cover 14 has a slightly larger fitting recess 14a, 1 having a similar shape of an inverse taper corresponding to the fitting projection 13a at the four corners.
4a, 14a, and 14a are formed so that fitting is possible. In particular, in the center of the fitting recesses 14a, 14a at both ends, and a rectangular reverse taper fitting recess 14b which is long in the lateral direction of the reverse taper is formed. As shown in FIG. 9, the medium-sized container 15 mainly for side dishes placed on the lid 14 has fitting projections 15 a fitted to fitting recesses 14 a, 14 a and 14 b.
15a and 15b. Fitting recesses 16a, 16a, 16b are formed on the lid 16 covering the container 15 so as to fit in the same manner as described above, corresponding to the fitting projections 15a, 15a; 15b. Although a small container for a side dish placed on the fitting recess 14a is not shown, its shape can be easily assumed from the above.

Although the fitting projections and fitting recesses of the lid-mounted container have been fitted to each other when they are stacked, in this embodiment, when two lid-mounted containers 13 are stacked, When medium and small containers are arranged on a large container and a large container is placed thereon, a rectangular fitting recess 14b is formed.
Is different from the configuration in that it is not involved in the fitting. In the above embodiment, the fitting projection is formed on the bottom surface and the fitting recess is formed on the lid surface.

Further, as shown in FIG. 10, a square-shaped inverted tapered fitting projection 18 is provided on the upper surface of a lid 18 covering the container 17.
a, a circular convex protrusion 18b, 18b having a reverse taper is formed, and the side dish container (shown in FIG. 12) 19 to be fitted therein is naturally formed with a fitting recess corresponding to the bottom surface, and is covered with a crown. the lid for fitting convex portion is formed. Further, the feature of this is that, for example, a cherry-shaped flower-shaped convex portion 18c is formed by being raised like a pattern, and a deep circular fitting concave portion 18d is formed at the center thereof. This fitting recess 18d is shown in FIG.
As shown in FIG. 2, it is formed in a size to fit the bottom of the cup 20, and is used as a base of the cup 20. The fitting recess 18d can be used not only as a cup but also as a fitting surface for a small side dish container.

The small container 21 placed on the fitting projection 18b has fitting recesses 21a, 21a corresponding to the fitting projection 18b. The lid 22 covering the container 21 may be provided with corresponding fitting projections 22a, 22a. In this embodiment, the case of using as a lunch box has been described. However, the present invention is not limited to the lunch box, and the range of use such as a small case can be freely expanded.

[0027]

[Effect of the Invention] Since the present invention is formed as described above, the present invention has the following effects. Arbitrarily combined containers can be connected and connected in multiple layers, so even when moving such as a hunk or a picnic, they can be safely brought without collapsing, and can be freely deployed depending on the number of people and the purpose. It is. And even if you want to warm a part of the side dish, it will not affect other side dishes.

In the case where the fitting surface of the lid is convex on the upper surface, the lid is turned upside down so that the back of the fitting portion becomes concave, so that it can be used as a dish for holding sauce, soy sauce and the like. In addition, the fitting recess of the lid is formed in a shape and size that the cup can fit, so even if it is unstable in the outdoors such as hiking, picnic etc., it is stable if the lid is placed on the ground and the cup is fitted on it It can be used effectively as a stand.
