DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a packaging container that can be expanded using far infrared rays.

[Conventional technology]

Traditionally, in the fresh food corners of shops and department stores, etc.
For example, raw meat, fish, their fillets, shellfish, vegetables, and other perishable foods or chilled foods are placed on a bottom plate made of polystyrene paper (PSP) shaped into a tray, and then covered with a packaging film. It is wrapped,
They are lined up in stores so that buyers can take them home.

Placing fresh foods on a tray-shaped bottom plate like this and wrapping them with a packaging film makes it easy to place them in store showcases, allowing customers to view the products through the film. Because of this, it is widely used as a simple packaging method.

[Problem to be solved by the invention]

However, with conventional packaging methods, neither the tray-shaped bottom plate nor the pack film have a water-absorbing function, so moisture and liquid from perishable foods accumulate inside, impairing their appearance and reducing their freshness. There is a risk that the product value may be damaged. Another problem is that moisture and liquid that seeps out of the fresh food accumulates inside the product while the purchaser takes it home, reducing its freshness. Therefore, especially in the case of a product with a high moisture content, it is necessary to take time and effort to package the product, resulting in poor workability. However, since fresh foods are easily spoiled by bacteria, special care must be taken to avoid contamination with bacteria during the packaging process.

Furthermore, even if a product can be cooked in a microwave oven, if moisture or liquid has accumulated inside the product, there is a problem that the product can be placed in the microwave without being forced to be removed from the packaging container. .

Furthermore, even if the product can be placed in a microwave oven, if the product releases moisture or liquid during the heating process, the packaging container itself does not have the ability to absorb water, so it may accumulate inside the product and cause the product to taste bad. There is.

The present invention was made in order to solve such conventional problems, and its purpose is to absorb water so that moisture and liquid do not accumulate inside it during display and transportation, so that freshness does not deteriorate. To provide a packaging container which prevents spoilage due to germs and allows direct cooking in a microwave oven.

The packaging container according to claim 2 of the present invention has a bottom plate and a side plate formed of a synthetic resin thin film kneaded with a far-infrared emitting substance, and the side plate is connected to the bottom plate so as to be expandable. A water-absorbing plate is placed on top.

The packaging container according to claim 3 of the present invention has a plurality of holes,
A side plate made of a synthetic resin thin film kneaded with a far-infrared emitting substance is connected to the bottom plate, which has a water-absorbing plate placed on the outside, and is placed on a bottom plate with multiple holes. The side plate is configured to cover the packaged item placed thereon.

In the packaging container according to claim 4 of the present invention, the bottom plate and the side plate are formed of a synthetic resin thin film kneaded with a far-infrared emitting substance, a plurality of holes are bored in the bottom plate, and the side plate is expanded to the bottom plate. The bottom body is freely connected and has a plurality of holes, and the side plate covers the article placed on the bottom body.

In the packaging container according to claim 5 of the present invention, a transparent or translucent portion is provided on the side plate formed of a synthetic resin thin film into which a far-infrared emitting substance is kneaded.

[For production]

In the present invention, water or liquid coming out of the product stored inside is absorbed by the water-absorbing plate and does not accumulate in the area where the product is placed. In addition, the synthetic resin thin film is constantly irradiated with far infrared rays, which sterilizes and maintains freshness.

Also, if you put it in the microwave while it is packaged and heat it,
Far-infrared rays are irradiated from a thin synthetic resin film that surrounds the product to detect, for example, proteins that make up the product.

It is efficiently absorbed by high molecular compounds such as starch and cellulose, and water molecules, and can effectively heat this product.

〔Example〕

Embodiments of the present invention will be described below based on the drawings.

1 and 2 show a packaging container according to a first embodiment of the present invention. In the figure, 1 is a sheet made of a synthetic resin film having a bottom plate 2 and four side plates 3, 4, 5.6 connected to the bottom plate 2.

This seat 1 has four side plates 3,4°5. excluding the bottom plate 2.
6 contains far-infrared material. This far-infrared material may be kneaded into the synthetic resin film when it is made, or it may be printed on the synthetic resin film as a design, such as a bamboo skin shape or a desired one-color pattern. A water-absorbing plate 7 is placed on the bottom plate 2 of the sheet 1. As the plate 7, a thermoplastic resin foam, water-absorbing cardboard such as blotting paper, or a sheet containing a water-containing polymer is used.

Next, the packaging container 10 configured in this manner will be explained.

First, as shown in FIG.
The three side plates 3, 4, 5.6 are raised in the same direction so that they cover the object 20 to be packaged. Next, as shown in FIG. 1, cellophane tape 8 is pasted to the area where the four side plates 3, 4, 5.6 overlap, and the four side plates 3, 4, 5.
Make sure that 6 does not separate.

In this state shown in FIG. 1, the intended packaging container 10 is obtained.

According to this packaging container 10, when moisture or liquid comes out from the packaged object 20, the water-absorbent plate 7 located below absorbs it, and no moisture or liquid accumulates on the bottom plate 2. . Therefore, the packaged item 20 is kept free from moisture and liquid, and deterioration in freshness and spoilage caused by accumulation of moisture and liquid are prevented. Furthermore, since the four side plates 3, 4, 5.6 that cover the packaged item 20 are always irradiated with far infrared rays, the freshness of the packaged item 20 can be maintained.

Furthermore, even when the purchaser is taking the packaging container 10 home, moisture and liquid coming out of the packaged object 20 are absorbed by the water-absorbing plate 7.
The liquid is reliably absorbed by the base plate 2, and no moisture or liquid accumulates on the bottom plate 2. Therefore, the packaged item 20 is kept free from moisture and liquid, and deterioration in freshness and spoilage caused by accumulation of moisture and liquid are prevented. Moreover, since the four side plates 3, 4, 5, and 6 that cover the packaged item 20 are always irradiated with far infrared rays, the freshness of the packaged item 20 can be maintained. Therefore, the four side plates 3, 4,
5. It is sufficient to use sellotape 8, which is easy to fasten 6.
There is no need to be as strict as before.

Furthermore, when this packaging container 10 is directly placed in a microwave oven and heated, far infrared rays corresponding to the amount of heat are irradiated from the four side plates 3, 4, 5. It is efficiently absorbed by polymer compounds such as cellulose and water molecules, and the packaged object 20 can be heated effectively.

FIG. 3 shows a packaging container according to a second embodiment of the present invention, and this embodiment differs from the above embodiment in that a water-absorbing plate 7 is provided on the outside of the sheet 1. . That is,
A plurality of holes 9 are bored in the bottom plate 2 of the sheet 1, and a far-infrared material is kneaded into the bottom plate 2 as well as the four side plates 3, 4, 5.6.

This embodiment also provides the same effects as those of the above embodiment.

In this embodiment, if there is a large amount of water or liquid coming out of the packaged object 20, it is desirable to increase the thickness of the plate 7 to improve water absorption performance.

Furthermore, in the present invention, the four side plates 3, 4, 56 have lost their transparency by incorporating far-infrared material, so that when the packaged items 20 inside the interior are displayed, etc. A transparent or semi-transparent region without far-infrared material incorporated therein may be provided in an appropriate size so that it can be viewed directly.

Furthermore, in the case of the sheet 1 shown in FIG. 1, the far-infrared material may also be incorporated into the bottom plate 2.

Further, in each of the above embodiments, the bottom plate 2 has a rectangular shape, but the bottom plate 2 is not limited to this, and can have any shape such as a round shape, a triangular shape, or a polygonal shape.

〔Effect of the invention〕

As described above, according to the present invention, since the bottom plate, the water-absorbing plate, and the side plate having a packaging function are integrated into one part of the tray, the article to be packaged is placed on the bottom plate or the water-absorbing plate. Packaging of items can be easily done by simply placing the container on the container and covering it with the side wall. Since moisture and liquid coming out of the packaged item are reliably absorbed by the water-absorbing plate, this does not accumulate inside the package and does not impair its aesthetic appearance, making it possible to increase the product value. Moreover, since far-infrared rays are constantly irradiated from at least the parts forming the side walls, freshness is maintained. Moreover, since the packaging itself is simple, the work does not take much time and effort.
