In this case, as means for maintaining a state in which the lid is closed with respect to the main body, protrusions protruding forward are provided on both sides on the front side of the main body facing the connecting plate on the back side. There has been known a configuration in which a claw-shaped locking piece provided on both sides of a lower portion on the front side of the lid portion is engaged below the protrusion (see, for example, Patent Documents 1 and 2 below). reference).
[0005]
[Patent Document 1]
Japanese Patent No. 10889214 for Design Registration
[Patent Document 2]
Japanese Unexamined Patent Publication No. 6-502831
[Problems to be solved by the invention]
However, in the case of a type in which the conventional claw-shaped locking piece is engaged or inserted as a locking structure for holding the lid in a closed state with respect to the main body, an engaging protrusion is used. And the like appear in the form of a protrusion, and another form is required in appearance. Further, a gap is formed in the portion of the engagement structure, and the heat inside can easily escape, and further improvement is required for applications requiring heat retention.
[0008]
SUMMARY OF THE INVENTION The present invention has been made in view of the above, and has been described as an engagement operation for maintaining a closed state as a food container including a main body portion and a lid portion connected from one sheet material such as paper. The engaging part does not appear to the outside, the appearance is good, and the engaging part has a double structure so that heat inside can hardly escape and good heat retention is maintained. The present invention provides a food container that can be used.
[0009]
[Means for Solving the Problems]
The present invention has been made to solve the above-described problem, and is formed from a sheet material having a thickness that can be folded, and is connected via a connecting plate on one side of the four circumferences, and each other except the one side. A food container comprising a main body portion and a lid portion formed by bending the side plate of the side, and the lid is configured to be able to be closed freely by being bent with the connecting plate as a center, wherein the connecting plate and The opposite side plate on the front side of the main body portion is connected to an outwardly folded engagement plate via a fold at an edge, and the front side plate of the lid portion facing the connection plate includes: A fold engagement plate inwardly is connected via a fold, and in the closed state, at least an edge portion of the fold engagement plate on the lid portion side is folded inside the fold engagement plate on the main body portion side. It is characterized by being engaged.
[0010]
According to this food container, in a state where food such as a hamburger is stored in the main body, the lid is put on the main body by being bent with the connecting plate at the center, and the lid is closed. At this time, the folding engagement plate connected to the front side plate of the main body is folded outside the side plate. Then, at the time of the closing operation of the lid portion, the folding engagement plate connected to the side plate on the front side of the lid portion is bent inward with respect to the side plate, and the edge side portion of the folding engagement plate of the main body portion is formed. Fold inward to engage. Thus, the lid is held in a state of being covered with the main body.
[0011]
In this closed state, the engagement portion between the folding engagement plate and the folding engagement plate is inside the side plate of the lid portion and cannot be seen from the outside, so that the packaging can be performed in a good format. In addition, since the engagement portion between the folding engagement plate of the lid portion and the folding engagement plate of the main body portion has a double structure, internal heat hardly escapes, and good heat retention is maintained.
[0012]
In the food container, the folding engagement plate of the lid portion is partitioned into an edge side portion and a connection side portion of the side plate by a fold parallel to a fold at a boundary portion between the front side plate and the side plate. The edge side portion is formed to be bendable with respect to the connecting side portion, and the edge side portion is folded inside while being bent outward to the inside of the folding engagement plate on the main body side. It is preferable to be provided so as to return to the unfolded state later.
[0013]
Thereby, when the folding engagement plate of the lid portion is folded inside the folded engagement plate of the main body portion in the lid closing operation, the edge side portion of the folding engagement plate is opposite to the folding direction with respect to the connecting side portion. By folding back in the direction, even if the distance between the side plate of the lid portion and the side plate of the main body portion is narrow, it can be easily pushed into the inside of the folding engagement plate. In addition, after being pushed in this way, the edge portion is returned to the original unfolded state with respect to the connection side portion while deforming the side plate, so that the edge portion is completely inside the folding engagement plate. Can be folded and engaged. In this engagement state, the leading end of the edge side portion of the folding engagement plate is folded to the vicinity of the bent portion due to the fold of the folding engagement plate, and there is also a shape retention property of a sheet material such as paper. The plywood can be held in the engaged state, and the closed state can be favorably held.
[0014]
The fold at the boundary between the side plate on the front side of the main body and the folded engagement plate is preferably formed by forming a perforated cut. That is, the folding engagement plate is folded outward at the cut-off folds to facilitate a mountain-folding when viewed from the inner surface side (the surface side in the unfolded state). The folded state (returned state) can be easily held, and the above-described closing operation and the engaging operation at the time of closing can be easily performed. Also, the fold cut is at the upper end of the side plate in the closed state and does not affect the seepage of the contents.
[0015]

Thus, the diagonal folds 4a, 4a and 4b, 4b are each outwardly mountain-folded so that the auxiliary ears 4, 4 extend along the inside of the extended ends 22b, 24b. The lid can be closed as shown in FIGS. 7 and 8.
[0033]
As a material to be used, for example, a paper sheet having a three-layer or two-layer composite structure in which corrugated paper is used as a core and liner paper is attached to both front and back surfaces or one surface thereof has a certain thickness. It is particularly suitable for use because it has a shape that is durable, foldable, and has elasticity and heat insulation. The paper sheet may be provided with a printed display or a resin coat layer on at least one surface as necessary.
[0034]
In addition, other suitable papers such as cardboard and corrugated paper, or various sheet materials mainly composed of paper can be used. Further, a sheet material obtained by laminating a synthetic resin film on a paper material may be used. It is also possible to use a foamed resin sheet that can be folded and has an appropriate shape-retaining property, but in practice, paper or a sheet mainly composed of paper is preferable.
[0035]
The thickness of the sheet material can be appropriately set in consideration of shape retention as a container, operability at the time of closing a lid, ease of folding, heat insulation, and the like. In the case of a paper sheet having the composite structure, a sheet having a thickness of 0.3 to 1.5 mm is usually used.
[0036]
In the production of the food container A of the present invention, the sheet material is punched and formed into a developed shape shown in FIG. 1 by using a Thomson blade, for example, with the inner surface of the container facing upward. At this time, each cut and each fold are also formed at the same time.
[0037]
For each fold, when punching and forming the sheet material mainly with the inner surface of the container facing upward, pressing the sheet material without cutting the portion corresponding to the fold with a pressing blade, A pressing groove is formed in the portion to form a fold. This fold is easy to bend (valley fold) with the pressing groove side inside, but relatively hard to bend to the opposite side. Therefore, as for the fold 13b between the side plate 13 of the main body 1 and the return engagement plate 16 that is mountain-folded when viewed from the container inner surface side, the return engagement plate 16 is easily folded outward by forming a perforated cut. Good to do.
[0038]
Since the fold 13b is located at the upper end of the side plate 13 in the assembled state and does not affect the seepage of the contents, there is no problem even if the fold is formed by the cut. In addition, there is no fear of seepage of the contents with respect to other folds due to the pressing grooves.
[0039]
Then, after being punched out in an expanded shape as described above, as shown in FIGS. 2 and 3, each side plate 12 to 14 of the main body 1 and each side plate 22 to 24 of the lid 2 are connected to the bottom plate 11 and the lid plate 21. And the adhesive connecting pieces 15, 15 of the main body 1 and the adhesive connecting pieces 25, 25 of the lid 2 are bonded to the adjacent side plates 12, 14, 22 and 24, respectively, to assemble.
[0040]
In this state, since the side plates 12 to 14 and 22 to 24 of the main body 1 and the lid 2 are in an open state, a large number of pieces can be nested, and handling such as storage and transportation can be performed. Easy.
[0041]
The folding engagement plate 16 connected to the side plate 13 on the front side of the main body 1 is folded outward from the fold 13b formed by the perforated cut as shown by the solid line in FIGS. It can be kept in a state of being folded, or can be kept unfolded as indicated by a chain line in FIG.
[0042]
Then, for use in a fast food store, for example, food such as a hamburger is stored, and the lid is closed as shown in FIGS. 7 and 8 in a procedure as shown in FIGS.
[0043]
That is, first, as shown in FIG. 4, the connecting plate 3 is bent substantially at a right angle at the fold 11 a at the boundary with respect to the main body 1, and the lid 2 is connected to the connecting plate 3 with the boundary at the boundary. The cover 2 is bent at a substantially right angle at the fold 21 a, and the cover 2 is put on the main body 1. Next, in a state where the folding engagement plate 16 connected to the front side plate 13 of the main body 1 is folded outward, the folding engagement plate 26 connected to the front side plate 23 of the lid 2 is folded. It is bent inward from the location of the eye 23b, and is folded and engaged with the inside of the folded engagement plate 16.
[0044]
At this time, when the folding engagement plate 26 is divided into an edge portion 27 and a connection side portion 28 by an intermediate fold 26a as in the illustrated embodiment, the end portion is located at the intermediate fold 26a. The edge portion 27 is bent outward, and the edge portion 27 is folded back into the engagement plate 16 while the side plate 13 and the like are deformed from between the side plate 13 of the main body 1 as shown in FIG. While being pushed in, and further pushed into the inside of the folding engagement plate 16, the edge side portion 27 is returned to the original unfolded state as shown in FIG. 6, and folded so as to overlap the inside of the folding engagement plate 16, and The tip is brought into contact with the inside of the bent portion by the fold 13.
[0045]
As a result, the main body 1 and the lid 2 are engaged with each other by the folding engagement plate 16 and the folding engagement plate 26 folded inside, so that the lid 1 is held in the closed state. In particular, the edge portion 27 of the folding engagement plate 26 is folded outward as described above, and the side plate 13 and the like are forcibly returned to the original state while being deformed while being inserted inside the folding engagement plate 16. Therefore, the edge portion 27 of the folding engagement plate 26 is not easily pulled out naturally, so that the closed state can be favorably maintained.
[0046]
In this closed state, the engaging portion between the folding engagement plate 16 and the folding engagement plate 26 is inside the side plate 23 on the front side of the lid 2 and is not visible from the outside, and the appearance is extremely good. is there. Moreover, in this closed state, the engagement portion has a double structure of the folded engagement plate 16 and the folded engagement plate 26, so that the internal heat is hard to escape and the heat retention is well maintained.
[0047]
When taking out the food inside, the folding engagement plate 26 is opened outward together with the side plate 23, and the side plate 13 of the main body 1 is pushed inward to be deformed and pulled out to be opened. Can be.
[0048]
In the above-described embodiment, the case has been described in which the main body 1 and the lid 2 are configured to be folded and closed at the boundary between the connecting plate 3 and the connecting plate. A fold may be formed in the middle portion of the connecting plate 3 so that the connecting plate can be opened and closed by the fold of the middle portion.
[0049]
