Description

The present invention relates to a packaging container for instantly completing packaging of a two-stage lunch at a low cost.

The heavy box was a two-tiered box (lacquer ware) that was born in the Muromachi period and holds dishes for Hare's day. Originally it was tableware, but there was also a demand for it as a takeaway item. A variety of dishes can be stored compactly, but a structure that simply stacks two layers is not possible as a packaging container. Furoshiki and strings were used for movement. In bento boxes and boxes, there were only complicated containers made of styrene or plastic that could be placed in a big box, moved by car and taken out.

Containers for circular foods such as pizza and okonomiyaki are square, so it's hard to take home. Therefore, I often took it home by car. For pizza, the habit of becoming almost home delivery has been created. In recent years, personnel expenses for home delivery have not gathered, and labor costs are a bottleneck. No "prior art document" or "patent document" is found.

The double-tiered tableware adds a special color to the dining table, just as the heavy boxes were used on the day of the festival. Originally lacquered, it is expensive and has no distribution. Therefore, many popular products of good quality made of resin have been made. However, it is not a cost that can be taken out, it is structurally the same as in the Muromachi era, it quickly falls apart, and I am nervous about moving.

For round foods such as pizza, the packaging container is a square with a complicated structure (to eliminate unevenness), which is difficult to carry. Also, foods with a large floor area are easy to cool.

Conventionally, the two-stage bento is against the resource-saving culture, and there has been a demand for a packaging container that is easily integrated and has high rigidity.

Since the take-out type conventional two-stage lunch container is integrated, it takes a lot of trouble at the joint portion, and then the whole must be covered with cardboard. The present invention solves the two projects that had to be developed at once. In the flow of enclosing the whole, the first-stage (1) (2) (3) (4) faces and the second-stage (5) (6) (7) faces are integrated.

The main body of A is simply a rectangle with six broken lines. It can be said that it is the ultimate resource-saving structure because there are no parts to cut and discard.

The main body of A is preferably cardboard or cheaper dumpler. Since the fold line has a hollow crease, it is easy to make a crease in that direction, and extremely rigid is provided in the direction in which the A main body opens (perpendicular to the crease).

B C may be an off-the-shelf product, but since A itself has rigidity, overall rigidity can be ensured even if it is thin at the level of drawing paper used by infants. This is because (8), (9), (10), and (11) of the middle box B C are braced even though they are thin.
The thinner the paper, the more energy saving. Even in the single-stage container constituted by the (3), (4), (5), (6), and (7) planes of A, the exposed portion of the inner box has a brace and has the same effect.

It can be said that the sizes of ready-made off-the-shelf lunch boxes are similar to each other. Therefore, if you make about 3 types of similar size A and sell them as one set, you can carry most bento lunch boxes compactly and as a two-stage lunch box.

Since it can be easily and cost-effectively made into a two-stage lunch, it will be widely used in station lunch boxes, lunch boxes, and convenience store lunch boxes. However, the ready-made middle box BC for a lunch box or the like is a plastic container with a lid, but because of its rigidity, many ribs are made and it is cheap. If you use the main body of A, you can use a simple one similar to the present invention BC, and you can make it a high-class and elegant design with the function of adding color to the original compactness of the heavy box.

The production cost can be kept low because it is the smallest class of material that can be used as a takeout heavy container.

As a heavy box container, the rigidity can be obtained with a simple structure, and the A main body can be manufactured in various sizes. That will come true with BC ready-made products.

Since it is a simple production, it enables speedy packaging work.

If you expand A body, you can put it on your thighs for meals such as buses and trains so that you can use it as a placemat that does not sag.

A main body development view The A main body is made only by the polygonal lines attached to the same surface of a to f. The A body is preferably made of cardboard or dumpler, in which case the creases (the part containing air) are parallel to the fold line.

A Completed drawing of the main body All the polygonal lines are mountain folds.

B C has a size that fits exactly into the two slits in the A main body completed drawing. In the packaging, first, C is wrapped with the (1), (2), (3), and (4) planes, and B is continuously wrapped with the (5), (6), and (7) planes. BC's (8)(9)(10)(11) are in a brace.

According to the revision of the consumption tax this year, the amount of take-away items is limited to 8%. The number of pizzas taken out at cafe restaurants and Italian restaurants will increase. Even if you take it home with you by car, the current square package will be nervous. If you take it in two steps in two minutes, it will be much easier to handle. Also, by changing the contents of the upper and lower tiers, the unique color of the heavy box when the packaging is opened is created. If you want a perfect circle, combine them. Moreover, if it is divided into upper and lower parts, the floor area will be halved, and the heat insulation effect of the upper part will be high, making it difficult to cool.

Since polypropylene pradan was developed as a curing sheet, it is easier than corrugated cardboard and 1 mm veneer, is resistant to water, and has high rigidity. Pradan is safe for the main body of the ekiben at the destination. Choose semi-transparent, and the function of the heavy box and the coloring of the ingredients make the ekiben more attractive. At the same time, there is an urgent need to take home the restaurant and develop special lunch boxes. There are many kinds of foods such as tempura and yakitori that you want to separate rice.

A main body is a translucent type of Pradan, and even a single-stage type has high rigidity, so it can be used as a soft food container. First, fruit sandwich. Even in Senbikiya, since it is the same plastic case as the container for yakisoba, you can use the A main body to create a high-class product. Similarly, both the one-stage type and the two-stage type can be used as take-out containers for cakes. Generally, cake paper boxes are not so rigid, so you can carry them with confidence.

It is also used for pottery shop packaging because it is rigid and can be packaged quickly. Similarly, there are many fruits, sashimi, etc. that are cheap and need rigidity, and that you want to package quickly.

INDUSTRIAL APPLICABILITY The present invention is basically used as a packaging container for a tertiary processed food to bring home, and is used in the food industry. Due to its low cost and high rigidity, it is also used as a breakable glass and as a take-away packaging container in the pottery industry.

In FIG. 1, the main body development view (1), (2), (3), (4), (5), (6), and (7) planes are distinguished by broken lines of abcdef.
1, A body assembly drawing abcdef is mountain-folded. The (1), (2), (3), (4), (5), (6), and (7) planes have the same symbols as I.
Fig. 2, BC middle box Ready-made product is also acceptable. In the case of off-the-shelf products, the dimensions of the A body will be determined according to the dimensions of each off-the-shelf product. The size of the BC middle box should, of course, be better matched to the size of the food. B C may be the same as C if the size of C is exactly the size of (1), (2), (3), and (4) of C. The rigidity of A is promised because the (8), (9), (10), and (11) planes of BC play a role of bracing. Although this surface is exposed, if the broken lines a to f of the corrugated board or the praddan are parallel to the respective creases, the rigidity does not matter even if the (8), (9), (10) and (11) surfaces are exposed. For pizza, you don't even need a lid.

Claims (5)

As is apparent from the A main body development view, the present invention has a simple rectangular shape, and there is no margin for assembling or a complicated cut portion. As a result, many similar shapes are extremely easy to make, providing a cost advantage over any packaging container that requires constant rigidity. In order to complete the packaging of an ordinary two-stage bento, the assembly work process for joining the first and second stages is complicated, but if there is a simple middle box BC, the rest will be a single package. One-action two-stage bento is completed. The main body of A can be made of ordinary thick paper, but since it is completed in one package, the side of BC is exposed. Therefore, it is desirable that the A main body is a corrugated cardboard or a praddan. In that case, even if the B C side surface is exposed, the rigidity is high in the direction orthogonal to the streaks of the A main body, and a package is realized. This simple structure also contributes to resource saving. The fact that the A body is simple means that it can be used for various shapes at a low cost. In other words, it will be possible to support off-the-shelf products. Japan's plastic lunch box size is very different, and if you sell a pack of A main body of about three sizes, you do not have to worry about taking home your lunch. It is also effective when carrying a number of packed lunches in a stack. As the consumption tax on take-away items will be cheaper, it is expected that lunch will increase at high-end restaurants. High-end restaurants often provide styrene two-stage bento, but it takes time to package them. The main body of the present invention A can be manufactured by matching the dimensions of each of the original inner boxes, and it is possible to provide an original take-away item that saves cost and does not require nerves.
