Description

[Detailed description of the invention] <Technical field> This invention relates to packaging containers for steamed foods, including shumai,
It relates to packaging containers for storing steamed foods such as meat buns and gyoza.

<Prior Art> It is widely practiced to package steamed foods such as the above-described shumai in a cooked or semi-cooked state and sell them as they are or frozen.

However, in order for consumers to eat the food they bring home, they need a steamer as a cooking utensil, but it is extremely troublesome to prepare a steamer each time and transfer the food from the packaging container to the steamer for cooking.
It was inconvenient to eat easily. For this reason, many people do not use a steamer and simply heat the food in a microwave or oven. If the lid is clogged, there is a problem in that dew condenses on the back of the clogged lid and the condensed water falls onto the steamed food, making it wet or sticky, which impairs the original taste of the steamed food.

<Purpose> Therefore, the purpose of this invention is to solve the above-mentioned problems of the conventional technology, and to provide a packaging container for steamed foods that allows steamed foods to be cooked while being stored in the packaging container and that can be eaten easily and deliciously. Our goal is to provide the following.

<Structure> The structure for achieving the above purpose is that the inner bottom plate is recessed inside the container body, floating slightly above the bottom surface, and the upper part of the container body is provided with a storage space for accessories. A recessed inner lid is fitted to form a chamber, and a large number of through holes are formed in both the inner bottom plate and the inner cover, and a water reservoir is formed between the bottom and the inner bottom plate. , the space between the inner bottom plate with through holes and the inner lid with through holes is formed as a steamed food storage section.

<Example> Next, an example of this invention will be described below with reference to the drawings.

As shown in Figures 1 and 2, 1 is a container body, which is formed from a synthetic resin sheet such as a foamed polystyrene sheet into a regular container shape such as a pot or cup by a sheet forming method such as vacuum forming. , is integrally molded.

Reference numeral 2 denotes an inner bottom plate, which is made of a sheet material such as a synthetic resin sheet, and is inserted near the inner bottom surface of the container body 1 with a slight space between it and the bottom surface, floating upward. The space is formed as a water reservoir, and in the case of the figure, a flat inner bottom plate 2 is placed in contact with above a stepped part 10 formed near the bottom of the container body 1. A steamed food F such as shumai is placed, and a water reservoir section, which is a space between the inner bottom plate 2 and the bottom surface of the container body 1, stores water for steam generation during cooking. The inner bottom plate 2 is provided with a large number of through holes 20 over the entire surface.
Used for passing steam.

Next, 3 is an inner lid, which is integrally molded from a synthetic resin sheet such as a transparent polystyrene sheet.
A fitting edge 30 that hangs downward is formed on the outer periphery. The inner lid 3 is detachably attached to the container body 1. Reference numeral 31 denotes a fitting protrusion, which is formed in a small protrusion on the inner surface of the fitting edge 30 and engages with the lower end of the flange portion 11 of the container body 1 to fix the inner lid 3 to the container body 1 by being fitted.
It's more reliable.

A storage chamber 32 is formed in the center of the inner lid 3 and is recessed downward from the top surface, and the outer wall of the storage chamber 32 is tightly fitted into the inner surface of the container body 1. This further ensures that the inner lid 3 and the container body 1 are fitted and fixed. Inside the storage chamber 32, sauces or sauces to be poured over the steamed food F, or accessories S such as chopsticks are stored.
In addition, the inner lid 3 has a large number of through holes 38 formed therein to prevent steam from condensing on the back surface of the inner lid 3 due to moisture from the steamed food F or steam coming from below. It is formed.

Further, reference numeral 4 denotes a removable sealing lid, which is made of a flexible synthetic resin sheet or the like, and is coated with or laminated with a thermal adhesive or the like.
2 and adhere it to the top surface of the inner lid 3, and then close the storage chamber 3.
2 is sealed. Reference numeral 40 denotes a knob piece, which is formed to extend from a part of the outer periphery of the seal lid 4 and is used when the seal lid 4 is peeled off and removed.

Next, a method of using the packaging container having the above structure will be explained.

First, when transporting, storing and selling the steamed food F, the steamed food F is placed on the upper surface of the inner bottom plate 2 in the storage chamber for steamed food between the inner bottom plate 2 with the through hole 20 and the inner lid 3 with the through hole 33. After storing the container body 1, the inner lid 3 is fitted onto the upper part of the container body 1 to cover it. The inner lid 3 is one in which accessories S such as sauce are stored in advance in the storage chamber 32, and then a seal lid 4 is pasted and sealed on the upper surface, and the inner lid 3 is fitted onto the container body 1 and covered.

When eating the steamed food F, as shown in FIG. Inject a small amount of water into 1 or close the inner lid 3.
Water is injected into the container main body 1 through the through hole 33, and water W for steam generation is stored in a space serving as a water reservoir in the lower part of the inner bottom plate 2.

Next, with the inner lid 3 closed, the entire container is inserted into a heating device such as a microwave oven or an oven range to heat the entire container. Then, the water W accumulated at the bottom of the container body 1 is heated and generates steam. The generated steam passes through the through hole 20 formed in the inner bottom plate 2 to steam and heat the steamed food F above, and then passes through the through hole 33 in the inner lid 3 and diffuses to the outside. Therefore, this wicking action can prevent dew condensation on the back surface of the inner lid due to steam from the moisture in the steamed food F or steam from the water reservoir at the bottom. and,
If the water W at the bottom of the container body 1 evaporates sequentially and the steamed food F can be completely steamed, remove the packaging container from the heating device and open the inner lid 3 of the container body 1, and the steamed food F can be steamed into the container body. The steamed food F can be used as tableware at the dining table while being stored in the container 1, and the steamed food F can be eaten as is.

In use, the sealing lid 4 may be peeled off at the initial stage of injecting water W into the container body 1, but the sealing lid 4 may be peeled off at the initial stage of injecting water W into the container body 1; It is also possible to make it difficult for heat and steam to escape from inside the container body 1 by leaving it attached to the container body 1. However, even in this case, it is necessary to peel off a portion of the seal lid 4 to provide a passage for the steam so that a certain amount of steam can escape to the outside of the container.

Furthermore, the accessories S stored in the storage chamber 32 of the inner lid 3 may be taken out from the inner lid 3 before the water W is poured into the container body 1, but the accessories S such as sauces and sauces etc. In this case, if the steamed food F is stored in the inner lid 3 while being cooked in a microwave oven or the like, the sauce or the like can be heated at the same time as the steamed food F is cooked.

Among the packaging containers described above, as the synthetic resin sheet forming the container body 1, foamed sheets made of various thermoplastic resin sheets such as foamed polystyrene sheets are suitable because of their excellent cushioning and heat insulation properties. A laminated sheet in which a non-foamed synthetic resin film is laminated on the foamed sheet, or a single non-foamed sheet can be used, and a laminated sheet of a synthetic resin sheet and paper, metal foil, etc. can also be used. However, any material needs to have heat resistance to the extent that it can be heated in a microwave oven or the like. Also, for the inner bottom plate 2 and the inner lid 3, sheet materials made of various synthetic resin sheets can be freely used.

Next, in order to place the inner bottom plate 2 floating near the bottom of the container body 1, as shown in the figure,
In addition to the structure in which the inner bottom plate 2 is placed on the stepped portion 10, a protrusion for supporting the inner bottom plate 1 is formed at the bottom of the container body 1, and a part of the inner bottom plate 2 is provided with a protrusion on the lower surface side. A protruding leg portion may be formed.

As long as the inner lid 3 can fit and cover the container body 1, in addition to the illustrated fitting structure with the fitting edge 30 and the engaging protrusion 31, various fitting structures similar to those used in ordinary packaging containers can be used. It is also possible to change the structure. Further, the shape of the storage chamber 32 can be changed as appropriate depending on the shape of the accessories S to be stored inside.
A partition or a stepped portion may be formed to separate and store the inner lid 3, or the storage chamber 32 may be formed only in a part of the center of the inner lid 3.

Further, as the sealing lid 4, one made of a removable synthetic resin sheet similar to that used for sealing conventional cup containers and the like can be used.

The steamed foods F that can be stored in the packaging container of this invention include siomai, meat buns, bean buns, gyoza,
Other foods that can be steamed and eaten can be used, and accessories S include additive foods such as sauces, sauces, soups, seasonings, and condiments, as well as eating utensils such as chopsticks, forks, and spoons, paper napkins, and toothpicks. It can also be stored.

<Effects> According to the packaging container of this invention configured as described above, the inner bottom plate 2 with the through hole 20 is inserted and arranged in a floating state near the bottom of the container body 1, so that the inner bottom plate Water W is placed at the bottom of 2 as a water reservoir.
By storing it in a microwave oven or the like and heating it, steam is generated from the water W, and the steamed food F placed on the upper part of the inner bottom plate 2 can be steam-cooked. In addition to being easy to steam and cook without using steamed food, there is no problem of spoiling the taste of steamed food F or making it hard, unlike simply heating steamed food F directly in a microwave, etc. Food F can be heated and cooked in a state where it can be eaten most deliciously.

Since the inner lid 3 is formed with a large number of through holes 33, the container body 1
The space between the inner lid 3 with the through hole 33 and the inner bottom plate 2 with the through hole 20 is formed as a storage space for the steamed food F to trap steam, and at the same time, the through hole 33 By letting a certain amount of steam escape, the steaming efficiency of the steam can be maintained in the best condition, and by letting the steam escape, dew condensation can be prevented from forming on the back surface of the inner lid 3 as described above. It also has a unique effect in that it prevents the steamed food F from becoming sticky or wet, allowing it to be cooked well.
