The present invention relates to sashimi in a main container,
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a boat-type folding container in which foods such as hot docks are put on the market and served for edible use, and liquid seasonings such as soy sauce and sauce are stored in a sub-container and can be added to foods such as sashimi and eaten.

[0002]

2. Description of the Related Art As a main / sub-integral type container of this type, there has hitherto been, for example, the one described in Japanese Utility Model Application Laid-Open No. 56-147271. According to this conventional technique, a second container formed by a container main portion different from a container main portion forming a first container is integrated with a flange formed on the outer periphery of an opening of both container main portions,
A food container in which a hinge function is formed in the flange portion between the both container main parts so that the contents in one container can be transferred into the other container.

[0003]

The above-mentioned prior art is made by heating and pressure forming from a thermoplastic resin sheet, so that it cannot be folded and a large number of containers are used in a distribution system (transportation / storage process). When making it bulky, inconvenient and space inefficient,
Moreover, since it is a simple cylinder or prismatic type main / sub-integral container, there is a problem that it has no taste and is dull.

[0004] In order to eliminate the above-mentioned problems, the present invention provides a large number of main and sub-integral containers which are not bulky in a distribution system and are made bulky by making the main and sub-integral containers foldable in a boat type. The purpose is to do.

[0005]

SUMMARY OF THE INVENTION An object of the present invention is to construct a folding container for assembling a cardboard or a plastic sheet by folding the cardboard from a folding line. A main side plate is connected to each side via a folding line, and an inverted trapezoidal front plate is connected to the front short side of the one main side plate via a folding line and a triangular folded piece is sequentially connected to the upper side via an external folding line. I do. A triangular sub-side plate is formed symmetrically on the oblique side of the folded piece via a fold line, and a glue allowance is continuously provided on each of these upper sides via an outer fold line, and a rear plate is provided on the rear side of the main side plate. A glue allowance is connected to each other via a fold line, and a glue allowance is formed on the side of the front plate via a fold line to form a deployment structure as a folding container.

In assembling, the rear plates of the main side plates that are erected by bending the respective pieces inward from the respective folding lines are joined together with a margin, and the erected front plate is glued with a margin. A main container surrounded by a bottom plate, a main side plate, a front plate, and a rear plate is formed by being attached to the front side of the main side plate. It was achieved by forming the hollow triangular pyramid-shaped sub-container surrounded by the sub-side plate and the folded piece by folding the side plate outward from the outer folding line together with the folded piece. The auxiliary side plate may be fixedly engaged with the front plate locking edge by the locking hook piece.

[0007]

[Function] To fold the above container, after flattening the bottom plate of the finished product as a loading container, the bottom plate, front plate, folded piece, sub side plate and rear plate are all inside from the fold line running in the length direction. The left and right main side plates can be folded in close contact with each other, so that even if a large number of them are superimposed, the bulkiness is small. It can be used by raising the center of the bottom plate while spreading from the bottom.

Further, instead of the above-mentioned folding method, the semi-finished container before the outward folding of the folded piece can be folded by folding all inward from the folding line in the same manner as above, and in this example, each plate piece can be folded. Since all of them can be folded into two pieces, the polymerization thickness is smaller than in the previous example, but the area is slightly larger.

The bottom plate of the folding container according to the present invention has a long elliptical contour, and the left and right main side plates are erected against the rigidity from the fold line along the elliptical contour, and the short sides are opposed to the rigidity of the material. When it is fixed by bending, each main side plate bends outwardly in a bow shape and becomes self-supporting, and the bottom plate is bent at the center in a raised state and is stable, and both main side plates can be firmly shaped by the rigidity of the material. Even when food such as sashimi is stored in the main container, the shape of the container as a shipping container can be stably maintained without being distorted.

[0010] In particular, according to the present invention, the two sub-side plates having the upper sides joined together are folded outwardly from the outer folding line together with the folding pieces, and when the sub-container is used upward, the outer container is removed from the vertical folding line. After the front plate and the folded piece that are folded in the direction, against the self-standing elasticity of the left and right main side plates, once flattened with fingers, etc.,
The auxiliary side plate is folded outward together with the folding piece outward from the folding line. If this folding angle, that is, the angle formed by the front plate and the folding piece is folded back to, for example, about 30 °, the bending restoring force of both main side plates will be increased. The folding piece automatically dents inward from the vertical fold line in the surface direction of the front plate as `` Pecon '' so that the outer surface of the folding piece and the outer surface of the front plate come into close contact, and this close contact state makes the left and right main side plates self-supporting. It can be secured due to its rigidity, and it is safe because it will not accidentally lose its shape during use of the sub container. Then, this sub-container is a hollow triangular pyramid with an upper part surrounded by the inner surface of the folded piece and the sub-side plate, and since the bottom part thereof is in a liquid-tight state,
It can be used safely without leaking even if a liquid seasoning such as soy sauce is added.

[0011]

EXAMPLES Examples will be described with reference to the drawings. In constructing a folding container for assembling a cardboard, a polycoated paper or a plastic sheet by folding it from a folding line, a folding line a is formed on each of the curved long sides of the substantially oblong bottom plate 1.
The main side plates 2 and 2 are connected to each other through a front side 3 of the one main side plate 2 and a front plate 3 having a trapezoidal edge 3A formed by an inverted trapezoid and having a triangular hole in the center through a folding line a at the front short side and an outer side at the upper side. The triangular turn pieces 4 are sequentially connected to each other via the fold line b. Triangular sub-side plates 5 and 5 are formed symmetrically on the oblique sides of the folded pieces 4 via folding lines a, and outer folding lines b are respectively formed on the upper sides thereof.
, A locking hook edge 6 is provided at the center end, and a seam allowance 5a, 5a serving as a bow as a loading vessel is continuously provided.

A rear plate 7 and a seam allowance 7a are respectively connected to the rear sides of the main side plates 2 and 2 via a fold line a, and a seam allowance 3a is provided on the side of the front plate 3 via the fold line a. It forms and constitutes the deployment structure as a folding container. Then, in order to assemble this, first, as shown in FIG. 3, the rear plates 7, 7 of the main side plates 2 and 2 which are erected by bending the respective pieces inward from the respective folding lines a are shown in FIG. 4 as well as the upright front plate 3 by the seam allowance 3a to the front side of the main side plate 2 as shown in FIG. 5, the bottom plate 1, the main side plates 2 and 2, the front plate. 3, the main container 8 surrounded by the rear plate 7 is constituted.

Further, the upper sides of the sub side plates 5, 5 are glued together with a glue margin 5a as shown in FIG.
7 and the folding piece 4 through the outer folding line b through the state of FIG. 7 and as shown in FIGS. 8, 9, and 10 are folded outward so as to be surrounded by the auxiliary side plates 5 and 5 and the folding piece 4. A sub-container 9 having a hollow triangular pyramid shape as in 1 is formed. Then, if necessary, the locking hook edge 6 of the lower free end may be engaged and fixed to the front plate hooking edge 3A to reinforce the bow part of the shipping container shown in FIG. The hooking edge 3A can be formed by a triangular hole having a V-shaped cut.

In order to fold the above-mentioned container, after flattening the bottom plate of the finished vessel container shown in FIG. 1, the bottom plate 1, the front plate 3, the folding piece 4, from the fold line a running in the length direction, Since the auxiliary side plates 5 and 5 and the rear plate 7 are all folded inward as shown in FIG. 13, the left and right main side plates 2 and 2 are brought into close contact with each other so that they can be folded up. Less tense,
One of them can be used by raising the center of the bottom plate 1 while expanding the bottom plate 1 together with the main side plates 2 and 2 from the vertical folding line a at a food or the like sales floor.

Instead of the above folding method, the semi-finished container before folding the folded piece 4 outward from the outer folding line b in the state shown in FIG. 6 is folded inward from the folding line a in the same manner as described above. 15, it is possible to fold as shown in FIG. 15. In this example, since all the plate pieces can be folded in two sheets, the overlapping thickness is smaller than that of the previous example, but the area is slightly larger.

The bottom plate 1 of the folding container according to the present invention has a long elliptical outline, and the left and right main side plates 2 and 2 are erected from the folding line a along the elliptical outline as shown in FIG. When the short sides are bent and fixed against the rigidity of the material as shown in FIG. 5 and FIG.
As shown in the figure, it bows outward and becomes self-supporting.
As shown in FIG. 11, the center is bent to a raised state to be stable, and the rigidity of the material allows both main side plates to be firmly shaped, and stores the food 10 such as sashimi in the main container 8 as shown in FIG. Even so, the shape as a ship-loading container can be stably maintained without being distorted.

In particular, in the present invention, when the two sub-side plates 5 and 5 having the upper sides joined together are folded outwardly from the outer folding line b together with the folded-back pieces 4 to use the sub-container 9 upward, The front plate 3 and the folded piece 4 that are bent outward from the vertical folding line a resist the self-standing elasticity of the left and right main side plates 2,
As shown in FIG. 4, after once flattened with fingers or the like,
Is folded outward together with the folded piece 4 from the outer folding line b as shown in FIGS.

When the turning angle, that is, the angle between the front plate 3 and the turning piece 4 is turned to, for example, close to 30 °, this time,
Due to the bending restoring force of the two main side plates 2, the folded piece 4 is automatically depressed “pecon” inward from the vertical folding line a in the plane direction of the front plate 3 as shown in FIGS. 10 and the outer surface of the front plate 3 are in close contact as shown in FIG. 10, and this close contact state can be ensured by the independent rigidity of the left and right main side plates 2 and 2, and the shape of the sub-container 9 is not degraded during use. It is safe.
The sub-container 9 is in the shape of a hollow triangular pyramid which is surrounded by the inner surface of the folded piece 4 and the sub-side plates 5 and 5 and has an open top, and the bottom is liquid-tight as shown in FIGS. 1 and 11. Therefore, even if a liquid seasoning c such as soy sauce is added, it does not leak and can be used safely (FIGS. 11 and 12).

[0019]

Since the present invention is configured as described above, it has the following effects. After flattening the bottom plate 1 of a finished product as a loading vessel, a fold line a running in its length direction
The bottom plate 1, the front plate 3, the folded pieces 4, the auxiliary side plates 5, 5 and the rear plate 7 are all folded inward, so that the left and right main side plates 2 and 2 can be folded in close contact. Has a small volume even if it is folded and polymerized, and thus has an economic effect in a distribution system that it can be transported and stored with good space efficiency. To use one of them, you can immediately use it by expanding the bottom plate 1 along with the main side plates 2 and 2 from the vertical fold line a at the food sales site and raising the center of the bottom plate 1 immediately. It can be quickly assembled and used in the seafood section and hot dog section of
There is also a benefit in use, as the waiting time for customers can always be shortened.

The bottom plate 1 of the folding container according to the present invention has a long elliptical contour, and the left and right main side plates 2 and 2 are erected against their rigidity from a fold line a along the elliptical contour, and the distance between the short sides is set. When the main side plates 2 and 2 are flexed and fixed against the rigidity of the material, each of the main side plates 2 and 2 flexes outwardly in a bow-like manner and becomes independent, and the bottom plate 1 is stabilized by the central portion flexing in a raised state, and the rigidity of the material is increased. The shape of both main side plates can be firmly preserved, and even if food 10 such as sashimi is stored in the main container 8, the taste as a loading container and the tasteful Japanese traditional form are stably maintained without being distorted. There is also a practical effect that it can be displayed well when displayed and displayed, and can be used safely when used.

In particular, in the present invention, when the two sub-side plates 5 and 5 whose upper sides are joined together are folded outwardly from the outer fold line b together with the folded-back piece 4, and when the sub-container 9 is used upward, The front plate 3 and the folded piece 4 that are bent outward from the vertical folding line a resist the self-standing elasticity of the left and right main side plates 2,
After being once flattened with fingers or the like, the side plates 5 and 5 are folded back.
When the folding angle, that is, the angle between the front plate 3 and the folding piece 4 is folded to, for example, about 30 °, the bending of the two main side plates 2 and 2 is restored. Due to the force, the folded piece 4 is automatically depressed inward from the vertical folding line a, that is, “pecon” in the surface direction of the front plate 3, and the outer surface of the folded piece 4 and the outer surface of the front plate 3 come into close contact with each other. The left and right main side plates 2 and 2 can be secured by the self-standing rigidity, and there is also an effect that the sub-container 9 is safe without being deformed even during use.

The sub-container 9 is a hollow triangular pyramid having an open top surrounded by the inner surface of the folded piece 4 and the sub-side plates 5 and 5. The bottom is in a liquid-tight state. There are many effects that the liquid seasoning c can be used safely without leaking even if it is put.

Furthermore, according to the second aspect, the lower free end of the sub-container 9 is hooked and fixed to the hooking edge 3A of the front plate 3 by the locking hook edge 6, so that the sub-container 9 can be further prevented from being deflected. It has a practical effect that it can be used comfortably.
