Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging container, and more particularly to a disposable packaging container for containing udon-suki material and the like.

[0002]

2. Description of the Related Art This type of packaging is usually a container made of aluminum foil, containing noodles, utensils, condiments, soup stock, etc., closed with a synthetic resin lid or covered with a wrap film. It is sold.

When it is served on a table, the lid or the wrap film is removed, and the soup stock, ingredients, etc. are put in a container together with the noodles and cooked, and appropriately boiled.

[0004]

However, storing noodles, ingredients, condiments, etc. together in the same container is messy and unfavorable in appearance, and an aluminum foil molded container is provided with a partition wall for separate storage. I can't do that either.

Further, it is not preferable in terms of keeping freshness that the vegetables and raw noodles used as ingredients are stored in the same place.

Further, since all the contents are put into the same container (pot) and boiled, it is not possible to enjoy the pot product while adding ingredients appropriately (for this purpose, a separate container must be prepared). There is a problem, such as outdoors.)

The above-mentioned various problems can be solved by preparing a plurality of containers and separately storing them. However, it takes time and effort to wrap each container and to assemble these containers. The problem of becoming bulky arises.

Therefore, an object of the present invention is to convert two completely separated containers into one packaging form.

[0009]

In order to solve the above-mentioned problems, a packaging container according to the first invention comprises a first container having a flange and a second container having a flange. A lid made of a heat-shrinkable film and having a margin outside the flange is heat-sealed, the flange and the flange of the second container are overlapped, and the margin is heat-shrinked to make the flange of the first and second containers. It is characterized by combining.

In the second invention, the first container is formed of a heat-shrinkable sheet, the skirt portion is provided on the flange, and the lid is heat-sealed on the flange of the first or second container. The two flanges are joined by superimposing and heat-shrinking the skirt.

In the third aspect of the invention, the lid is heat-sealed on the flange of the first container, the flange of the second container is superposed, and the heat-shrinkable film band is wound around the outer periphery of these flanges. Then, the flanges of the first and second containers are connected by heat shrinking.

[0012]

Since the lid is heat-sealed to the first container, the first and second containers are completely separated. Further, since the flanges are overlapped with each other and connected, a single packaging form is provided, which is convenient for handling.

If one container is used as a pan,
You can boil while adding ingredients from the other container.

[0014]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

As shown in FIG. 1, the packaging container of the present invention comprises a first container 10 and a second container 20.

The first container 10 has a bottom wall 11 and a peripheral wall 12, and a flange 13 is provided on the peripheral edge of the opening at the upper end of the peripheral wall 12.

Similarly, the second container 20 also has a bottom wall 21 and a peripheral wall 22, and a flange 23 is provided on the peripheral edge of the opening at the upper end of the peripheral wall 22.

The first container 10 and the second container 20 may have any shape such as a circular shape, an elliptical shape, a polygonal shape or the like, but preferably have substantially the same shape, and the sizes thereof are the flanges 13 and 23 as described later. Make the size so that they overlap.

The containers 10 and 20 and the material used may be a simple substance such as synthetic resin, paper, glass, metal foil, or a composite. For example, the container 10 is a molded product of a synthetic resin sheet, and the container 20 is an aluminum foil. It is a molded product.

After the contents such as soup stock, ingredients, and condiments are stored in the first container 10, the lid 30 made of a heat-shrinkable film is heat-sealed to the flange 13. In the figure,
Reference numeral 31 is a heat seal portion, and 32 is a margin extending outside the flange 13.

As the heat-shrinkable film, oriented polypropylene, oriented polystyrene or the like is used. Further, the shape of the lid 30 may be formed in conformity with the shape of the flange 13 of the container 10, but if the container 10 is circular, for example, it may be circular as a whole as shown in FIG. Three
As shown in FIG. 5, the margin 32 can be formed in an appropriate shape such as a petal. Of course, the heat seal portion 31 needs to match the shape of the flange 13.

Next, for example, raw noodles are stored in the second container 20, and as shown in FIG. 4, the first container 10 is reversed and its flange 13 is overlapped with the flange 23 of the second container 20, The container 10 is placed in the opening of the container 20. Then, hot air is blown from around the overlapped flanges 13 and 23 to shrink the margin 32 of the lid 30, and the flange 2
Wrap it around 3. Thereby, the flange 13 and the flange 23 are connected, and the opening of the second container 20 is also covered with the lid 30.
Closed by.

In this way, the first container 10 and the second container 20 form a single packaging form, and the lid 30 is a common lid that closes the openings of both containers 10 and 20.

As shown in FIG. 5, the first container 10 is
The size of the container 20 is smaller than that of the container 20, and the flanges 13 and 23 are overlapped so as to fit into the second container 20.
It may be wrapped around and the flanges 13 and 23 may be connected to form a single packaging form.

FIG. 6 shows another embodiment. As shown,
The first container 10 is formed of a heat-shrinkable sheet, and a skirt portion 14 extending from the outer periphery of the flange 13 thereof is provided. Then, the lid 30a is heat-sealed to the flange 13. The lid 30a is made of a material having no heat shrinkability, and it is not necessary to provide the margin 32 (FIGS. 1 to 4) as described above. The second container 20 may be similar to that of FIG.

Then, as shown in FIG. 7, the first container 1
When 0 is reversed and the flange 13 is overlapped with the flange 23 of the second container 20 and hot air is blown onto the skirt portion 14 to shrink the skirt portion 14, the skirt portion 14 has the winding flanges 13 and 23 connected to the flange 23, It becomes one packaging form.

As shown in FIG. 8, the skirt portion 14 is shown in FIG.
And the first container 10 as shown in FIG.
May be fitted into the second container 20 and the skirt portion 14 may be heat-shrinked to join the two containers 10 and 20 together.

As shown in FIG. 10, a container 1 similar to that shown in FIG.
0 and 20 are prepared, and the lid 30a similar to that shown in FIG. 6 is heat-sealed to the flange 13 of the container 10. Then, as shown in FIG. 11, the container 10 is reversed and its flange 13 is overlapped with the flange 23 of the container 20, and as shown in FIG.
A ring 40 wrapped around the flanges 13 and 23 with a heat-shrinkable film strip 40 or made of a heat-shrinkable film.
Alternatively, the flange 13 and the flange 23 can be connected to each other by heat-shrinking the film strip or the ring 40 by inserting.

Of course, also in this case, as shown in FIGS. 5 and 9, the container 10 may be fitted inside the container 20.

[0030]

According to the present invention, as described above, the lid is heat-sealed on one of the flanges of the first container and the second container,
The two are superposed and the two flanges are joined with a heat-shrinkable film, so both containers are completely separated by the lid, but they become an integrated packaging container.For example, by separately storing the utensils and noodles, the freshness can be maintained well. In addition, the appearance is preferable, and the heat-shrinkable film necessary for integral packaging is not only sufficient but can be firmly integrated.

Further, for example, it becomes possible to package the soup stock and the ingredients in a factory or a trader other than the noodles, and combine the two for sale.

In addition, even when serving at a dining table, it is possible to enjoy while adding ingredients and the like from one container to the other container (pot) without preparing another container.
