On a steamer, which is a steamer composed of a structure in which the above frame is surrounded by a bamboo-made top lid and a bamboo cage bottom, rice cooked in advance for 7 minutes and on top of that rice, seafood, meat, mushrooms, seasonal Various ingredients such as vegetables are put on it and steamed completely with steam.
[0003]
In addition, the above-mentioned steamed rice is a steamed hot rice, the fragrance of cedar and the original taste of various ingredients placed on the rice are transferred, and the appetite is apprehended, and the tasteful directivity is preferred. It is always a popular menu at restaurants. Furthermore, some restaurants specialize in various types of ingredients, devising a variety of ingredients, devising many types of rice, and gaining popularity.
[0004]
Local restaurants that provide such rice have traditionally provided a souvenir lunch box for souvenirs in response to customers' requests.In this case, however, it is used for the rice served in the store. Instead of the original wooden bowl, a simple lunch box made of paper was used.
[0005]
Here, the above simple lunch box containers are "simple seiro" of Japanese Utility Model Publication No. 58-17541, "simple seiro" of Japanese Utility Model Publication No. 60-16330, and "Simple Seiro" of Japanese Utility Model Publication No. 1-62725. And Japanese Patent Application Laid-Open No. Hei 9-252954. Therefore, the outline is described below.
[0006]
First of all, referring to the "Simple Seiro" of Japanese Utility Model Publication No. 58-17541, the gist of the paper is that the upper end of the cylindrical body is opened and the bottom is provided with a bottom body having a plurality of holes. The inner surface of the bottomed container is coated with a heat-resistant synthetic resin, and is composed of a wax main body having an aluminum foil adhered to the outer peripheral surface of the cylindrical body, and a paper lid covering the upper end of the cylindrical body. It was simple.
[0007]
Next, "Simple Seiro" of Japanese Utility Model Publication No. 60-16330 is a simplified seiro that has a simple stacking structure, the gist of which is formed of a foldable material such as paper or metal, and the lower end is formed. A cylindrical body folded inwardly upward, and a plurality of holes that are bent to a length that does not reach the bottom of the folded depth of the lower end of the cylindrical body, and a plurality of holes are formed, and a bottom having a diameter matching the inner diameter of the cylindrical body. The body was simply inserted by inserting the bent portion of the bottom body into the folded portion of the tubular body and pressing the hollow portion of the folded portion of the tubular body stepwise from the outside.
[0008]
Next, the "Simple Seiro" of Japanese Utility Model Laid-Open No. 1-62725 is a type in which a vertical folding line is provided on the main body of the seiro so as to make it foldable so that it does not take up space for storage. A cylindrical body having a step toward the bottom, a circular plate fitted into the step and a bottom plate having a hole, and a lid covering the upper end opening of the cylindrical body, wherein the cylindrical body and the bottom plate are made of paper. The heat-resistant resin layer was mainly provided, and the heat-resistant resin layer was provided on the inner and outer surfaces, and a vertical fold line for flat bending opposed to the cylindrical body was provided.
[0009]

[0010]
[Problems to be solved by the invention]
Here, when examining the "simplified seiro" and "assembled seiro" described in the section of the prior art, these are basically inexpensive materials, such as paper or metal, which can be bent to the original shape of a wooden sewer. It is considered to have been reproduced by such means. However, when considering the method of providing a restaurant related to a souvenir lunch box as a souvenir, it is obvious that the method of providing a rice bowl consumed in a restaurant and a lunch box taken out of the restaurant are different. It is different. Specifically, the difference is that the steamed rice consumed in the store is provided to the customer's seat in the state of steamed hot steamed steamed rice cooked in the kitchen, The lunch box which is taken out is a steamed lunch box, which is made by steaming rice cooked in a 7-minute bowl into a steam-type lunch box, and steaming the various ingredients on top of it in a kitchen. As it is, it is provided to customers after being wrapped with wrapping paper, paper strings, etc. in order to adjust the appearance as a souvenir.
[0011]
Thus, in the case of a lunch box container used as a souvenir as described above, the temperature was initially hot, but the temperature decreased with the lapse of time after takeout, and remained in the container along with it. The condensed water condenses, and the condensed water seeps out of the perforated bottom plate provided for steaming, contaminating the wrapping paper, and also when unpacking the wrapping paper contaminated by the condensed water. There was a drawback that the wrapping paper was inadvertently torn if it was hit, and the appearance as a souvenir was extremely bad.
[0012]
Furthermore, since the bottom plate side of the cylindrical body in the container structure is constituted by a single perforated plate from which the heat inside the container easily escapes from the container structure, the heat retaining property is poor. There was a drawback that it was easy to cool. Then, because it is a easy-to-cool lunch box type lunch container, although it is a souvenir product called hot rice with hot water, when the container was opened, steaming did not stand up and the utensils and rice that appeared to cool down appeared. There was also a drawback that the value as a souvenir was reduced without apprehension and appetite.
[0013]
The present invention has been made in view of the drawbacks of the lunch box container described in the section of the prior art, and has a high heat retaining property and the dew water in the container is outside the container from the perforated bottom plate. It is an object of the present invention to provide a lunch box container which does not infiltrate into a wrapping paper and does not contaminate a wrapping paper or the like wrapped to adjust the appearance as a souvenir.
[0014]
[Means for Solving the Problems]
In order to achieve the above object, the lunch box container according to the present invention is formed of a bendable material such as paper, and is coated with a heat-resistant synthetic resin on an inner surface and has a lower peripheral portion. And a hollow polygonal column that is turned upward inside, and a jet for effectively introducing steam into the container at the center of the bottom plate at a slight distance from the lower end of the cylinder or hollow polygonal column in the vertical direction. A steam introduction hole is formed, and a first bottom plate having a shape coinciding with the horizontal inner peripheral wall shape of the cylindrical body or the hollow polygonal column is formed by forming a bent portion downward, and the cylindrical body or the hollow body is hollowed out. Insert the bent portion of the first bottom plate into the folded portion of the polygonal column, press the hollow portion in the folded portion from the outside, and further correspond to the predetermined interval so as to be separated from the crimping position of the first bottom plate by a predetermined distance. Fold length The bent portion is provided below and a second bottom plate having a shape that matches the horizontal inner peripheral wall shape of the cylindrical body or the hollow polygonal column is inserted from the upper opening of the cylindrical body or the hollow polygonal column. The gist of the present invention is that the tip of the bent portion is disposed in contact with the first bottom plate, and a sealing seal for sealing the jetted steam introduction hole is provided.
[0015]
Here, as the resin used for coating with the synthetic resin described in the above summary , a polyester-based resin such as polyethylene terephthalate and a polyolefin-based resin such as polymethylpentene are preferable. Subsequently, the sealing seal described in the above summary is configured such that when wrapping a steamed lunch box steamed as a souvenir, the jetted steam introduction hole is sealed by the seal in advance, so that the inside of the lunch box container is sealed. In order to prevent the condensed water condensed from leaking out of the lunch box, the seal does not need to be a special seal and may be another as long as it can be used instead. Furthermore, it is preferable to form a step at the lower end of the cylindrical body or hollow polygonal column of the lunch box container described in the above summary when stacking the lunch box containers.
[0016]
Further, in the steam-type lunch container according to the present invention, if a break line or a cut is engraved so that the first bottom plate can be separated from the lunch-box container body as necessary, the case where the yellow lunch is cooled However, apart from the above-mentioned first bottom plate, in addition to the steamer for general household use, steam generated from the steam circulation hole of the second bottom plate of the lunch box container also by a substitute that is configured to fill a pot to generate steam. Penetrates into the container and can be regenerated into hot steamed rice again.
[0017]
[Action]
The steam-type bento container according to the present invention is for vertically introducing a vapor into the bottom plate center portion slightly vertically separated from the lower end to the lower end side of the bottomed hollow cylindrical body or the bottomed hollow polygonal column. A first bottom plate provided with a jetted steam introduction hole is provided, and a plurality of steam flow channels for flowing steam are further vertically spaced apart from the position where the first bottom plate is provided at a predetermined interval. Since the second bottom plate in which the holes were perforated was arranged, when the steamed lunch box steamed for souvenirs was packaged, the above-mentioned spouted steam introduction hole was previously sealed by the provided sealing seal. Thus, the dew water condensed in the lunch box does not leak out of the lunch box to contaminate the wrapping paper.
[0018]
Next, in the spring-type lunch container according to the present invention, if a step is formed at the lower end of the cylindrical body or the hollow polygonal column of the sail-type lunch container, a plurality of lunch containers of the same type can be stacked, Sometimes it works to steam multiple lunch boxes.
[0019]
Subsequently, in the steam-type lunch container according to the present invention, if a break line or a cut is engraved on the first bottom plate so that the first bottom plate can be separated from the lunch container main body, the lunch box is cooled. Even in this case, if the first bottom plate is cut off along the breaking line or cut, and then put in a substitute for general household steamer or a substitute which is filled with water in a pot to generate steam, the lunch container is provided. The steam generated from the steam flow hole of the second bottom plate permeates into the container and acts to be able to regenerate hot steamed rice again.
