DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a food package, and more particularly to a note-lay type package most suitable for packaging side dish foods.

[0002]

2. Description of the Related Art Conventionally, as a package for selling various prepared foods so that they can be brought back home as they are, products are generally arranged in a tray made of synthetic resin such as styrene foam, and a transparent resin is placed on the tray. The film is wrapped and displayed in a store in a sealed state so that the product can be seen through from the outside so as to be offered for sale, and the consumer can take it home after purchase.

[0003]

However, in the above-mentioned conventional package, it is necessary to arrange and wrap the products in trays formed into a dish shape by using styrofoam or the like. Many kinds of materials are required, and in addition, trays and wraps are discarded as non-combustible garbage, which is not only bulky but also involves problems in garbage disposal, and wasteful consumption of resources is pointed out. Further, when heating is required, there are various problems such as heating (or thawing) cannot be performed in an electronic cooking device (microwave oven) as it is. On the other hand, in a format in which merchandise is packed in a bag at a store and sold, the merchandise is manually packed one by one, so that there is a disadvantage that sales efficiency is low.

[0004] In view of the above, an object of the present invention is to provide a note-ray type package in which the state of a product can be seen from the outside, the condition of the product can be confirmed, and the product can be sold as it is. Further, by selecting the material of the packaging material, it is possible to provide a packaging body which can directly cope with heating (thawing) by an electronic cooking device.

[0005]

As a means for solving the problems of the above-mentioned prior art, the present invention is to provide a highly transparent film having a required width at an intermediate portion and peeling the film on both sides of the film. A packaging material consisting of a sheet having a breathable, water-absorbing, water- and oil-resistant property, which is joined to the film portion of the packaging material, the food is placed on the film portion, the sheet portion is wrapped with the packaging material, and the joined end is sealed. It is characterized in that both ends are sealed and packaged together with the film.

[0006] When packaging warm prepared foods, the film is preferably subjected to an anti-fog treatment. In addition, it is desirable from the viewpoint of refuse treatment that the sheet be made of a paper base material and a wrapping material having water resistance and oil resistance added thereto.

[0007]

[Function] A food product is placed on the back side of a film of a packaging material, and the sheets joined on both sides of the film are folded on the product to seal the joined ends of these sheets, and the sheets at both ends are sealed. The product is packaged in a sealed state by overlapping and sealing the film. By arranging them in the store, the inside product can be seen from the outside through the film, and the consumer can check the condition of the product, purchase it, and take it home.

[0008] When opening, grasp the edge of the film on the upper surface and peel off, the product can be easily taken out,
By stripping the film, combustible dust and non-burnable dust are divided, and the problem of dust disposal is solved, resulting in an environmentally friendly package.

If the film and the sheet are made of a material having heat resistance, the film and the sheet can be heated (or thawed) by an electronic cooker as it is. In addition, if the film is subjected to anti-fogging treatment, the film will not be clouded by steam even if hot prepared foods are wrapped, and the inside product will not be difficult to see.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to embodiments shown in the drawings.

FIG. 1 shows the packaging material 1 and FIG.
As shown in an expanded view, a highly transparent film 2 having a required width is located at an intermediate portion, and sheets 3 and 3 made of paper are joined to both sides by seals 4 and 4, respectively. The seals 4 and 4 have such strength that the film 2 can be peeled by hand.

As the film 2, for example, a polyolefin-based material having high transparency such as polypropylene is used. For the sheets 3 and 3, for example, a fluororesin processing 5 is applied to the surface as shown in an enlarged cross section in FIG. A material which is rich in ventilation, water absorption, water resistance and oil resistance, such as so-called synthetic fiber mixed paper, in which a heat seal layer 8 having a fluororesin treatment 7 applied to the surface layer 6 (paper quality) is laminated, or a mixed special paper. A paper material having a heat seal layer on both surfaces is used.

At the time of packaging, as shown in FIGS. 4 and 5, a commodity 9 such as a prepared dish is placed on the back side of the film 2 of the packaging material 1, and the left and right sheets 3 and 3 are folded thereon. , 3 are joined to hot rolls 10, 10,
After passing between the cooling rolls 10a, 10a, a seal 11 (heat sealing) is performed and closed (FIG. 1). Then, the film 2 and the sheets 3, 3 are pressed at both ends by a hot press 12 and a cooling press 13, The seals 14 and 14 (heat seal) are separated from each other along the cutting line 15 at the seal 14, and the product 9 is packaged in a hermetically sealed state (pillow packaging, reverse pillow packaging).

Thus, the sheets 3 and 3 have a function as a plate, and can be displayed side by side in a store with the film 2 as the upper side, and the consumer can see the type and condition of the product 9 inside through the film 2. The user can clearly check the package 16 and can take it home after purchasing the package 16 containing the desired product 9. In this case, the steam is appropriately released from the sheet 3 to maintain the crisp texture of the prepared food. Further, even when heated by the electronic cooker, there is no reversion of moisture or oil content, and there is no sticky feeling.

When the product 9 is taken out, the film 2 on the upper surface is taken out.
If you pinch the corner and peel off, film 2
, And the product 9 can be easily taken out. By removing the film 2, the combustible dust (the sheet 3) and the non-burnable dust (the film 2) can be separated, and the dust treatment can be easily performed.

If the film 2 and the sheets 3 and 3 are made of materials having heat resistance, they can be directly heated by an electronic cooker after purchase, or can be heated and thawed in the case of frozen food. In addition, if the film 2 is used with anti-fogging treatment, it is possible to prevent the inside of the film 2 from becoming cloudy due to steam even when warm prepared foods are packaged.

As a form of packaging, as shown in the drawing schematically shown in FIG.
(Gazette) can be inserted to correspond to the form and quantity of the product, and the film 2 is not necessarily located at the center, but is moved to one side as shown in FIG. May come to the end (see FIG. 7). Furthermore, the film 2 is not the outer surface of the sheets 3 and 3,
You may make it join to an inner surface side.

Each of the above-mentioned seals may be packaged one by one using a normal heat sealer.
Is formed in a piece shape long as shown by a chain line 1a in FIG.
A large number of packages 16 may be formed in a factory by a special packaging machine that sequentially packs the products 9 while feeding the same. In the case of frozen foods and the like, the packaging body 16 is not separated at the seal 14 portion, but is perforated instead, so that the consumer can separate and use one bag at a time. In addition, wrap multiple bags with exterior materials,
Similarly, one bag may be taken out and used.

As an object to be packaged, in addition to the above-mentioned prepared foods, it can be used for meat, marine products (frozen fish, etc.), processed foods, and the like.
It is preferable to partially waterproof the surface, and in the case of marine products, it is also possible to use water supply paper separately.

Further, the strength of the sheets 3 and 3 can be increased by subjecting the sheets 3 and 3 to a folding process (embossing) in the longitudinal direction.

[0021]

As described above, according to the present invention, a film having high transparency is provided in the middle portion, and ventilation films are provided on both sides thereof.
The food, which is a product, is wrapped with a wrapping material that is bonded to a sheet that is highly water-absorbing and water- and oil-resistant, so that the sheet plays a role of a dish for the product and the film plays a role of a window for checking the product. As a result, consumers can see the whole of the product inside through the film, can take it home when purchasing, and have the same convenience as a package using a conventional tray. In some cases, the product can be easily taken out simply by peeling off the film, and after taking out the product, the sheet portion becomes a plate, and since there is no tray, the amount of dust can be reduced and the processing becomes easy.

If a heat-resistant material is used for the film and the sheet, it can be heated (or thawed) by an electronic cooker while being packaged, and can be handled with high safety and can be easily handled. A package that can be easily made can be obtained. Further, by using the film subjected to the anti-fogging treatment, it is possible to prevent the film from fogging and the product from being difficult to see even when hot prepared foods are packed.
