Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a Notley-type package which is most suitable for packaging food such as prepared foods.

[0002]

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

[0003]

However, in the above-mentioned conventional packaging body, since the products must be lined up on the tray formed in the shape of a plate with styrofoam or the like and wrapped, it is not only labor-intensive for packaging but also at the time of packaging. It requires various kinds of materials, and the trays and wraps are not only bulky because they are discarded as non-combustible waste, but also have problems in waste disposal and wasteful consumption of resources is pointed out. Further, there are various problems such as when heating (or thawing) may not be possible in an electronic cooker (microwave oven) as it is when heating is required. On the other hand, in the format in which products are packed in bags and sold at the store, the products are hand-packed one by one, so that the sales efficiency is low.

In view of this, it is an object of the present invention to provide a note-lay type packaging body in which the state of a product can be seen from the outside and the state of the product can be confirmed and then sold as it is. Further, it is possible to provide a packaging body that can directly cope with heating (thawing) by an electronic cooker by selecting the material of the packaging material.

[0005]

As a means for solving the problems of the above-mentioned conventional techniques, the present invention is directed to a highly transparent film located at an intermediate portion and having a required width, and peeled to both side portions of the film. Equipped with a packaging material consisting of a sheet that is air-absorbent, water-absorbent, water-resistant, and oil-resistant and is joined as much as possible, put a product such as a side dish on the film portion of the packaging material, wrap it with the sheet portion, and join the joint end. It is characterized in that both ends are sealed and sealed together with the film.

In the case of packaging warm side dishes, it is preferable that the film is subjected to an antifogging treatment. Further, it is desirable for the above-mentioned sheet to use a packaging material in which paper is used as a base material and water resistance and oil resistance are added to it in terms of dust disposal.

[0007]

[Function] The product is placed on the back side of the film of the packaging material, the sheets joined to both sides of the film are folded over the product to seal the joint ends of these sheets, and the sheet and the film at both ends are separated. The products are packaged in a sealed state by stacking and sealing. By arranging them in stores, the products inside can be seen through the film from the outside, and consumers can check the condition of the product and purchase it before taking it home.

At the time of opening the package, if the end of the film on the upper surface is pinched and peeled off, the product can be taken out easily.
By peeling off the film, combustible dust and incombustible dust are separated, and the problem of dust disposal is solved, resulting in an environmentally friendly package.

If the film and the sheet are made of heat-resistant material, they can be heated (or thawed) as they are in an electronic cooker. Further, when the film is anti-fog treated, even if warm side dishes are packaged, the film will not be fogged by water vapor and the products inside will not be difficult to see.

[0010]

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

The packaging material 1 is shown in the packaged state in FIG.
As shown by expanding the individual pieces, a highly transparent film 2 having a required width is located in the middle portion, and sheets 3 and 3 having paper as a base material are joined to both sides by seals 4 and 4, The seals 4 and 4 have such strength that the film 2 can be peeled off by hand.

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

At the time of packaging, as shown in FIGS. 4 and 5, a commodity 9 such as a side 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 on top of it, and the sheet 3 , 3 are joined to the heat rolls 10, 10,
A seal 11 (heat seal) is passed through between the cooling rolls 10a, 10a to close them (FIG. 1), and then the film 2 and the sheets 3, 3 are pressed at both ends by a hot press 12 and a cooling press 13, By sealing 14 and 14 (heat sealing) and separating the seal 14 along the cutting line 15, the product 9 is packaged in a sealed state (pillow packaging, reverse pillow packaging).

As a result, the sheets 3 and 3 have a function as a plate, and the film 2 can be displayed side by side in the store with the film 2 as the upper side, and the consumer can see the kind and condition of the product 9 inside through the film 2. It can be clearly confirmed, and the package 16 containing the desired product 9 can be taken home after purchase. In this case, water vapor is appropriately released from the sheet 3 to maintain the dry texture of the side dish. Moreover, even if heated by an electronic cooker, there is no reversion of water or oil, and no sticky feeling occurs.

When the product 9 is taken out, the film 2 on the upper surface
Pinch the corners of the film and peel it off to get the film 2 into sheets 3 and 3.
The product 9 can be easily removed, and by removing the film 2, the combustible dust (sheet 3) and the incombustible dust (film 2) can be separated, and the dust treatment can be facilitated.

If the film 2 and the sheets 3 and 3 are made of a heat-resistant material, they can be heated by an electronic cooker as they are after purchase or can be heated and thawed in the case of frozen food. Further, by using the film 2 which has been subjected to anti-fog treatment, it is possible to prevent the inside from being obscured by steam even if warm side dishes are packed.

As for the packaging form, as shown in the schematic view of FIG.
The shape and quantity of the product can be adjusted by inserting (gazette), and the film 2 is not necessarily located at the center, but can be moved to one side as shown in FIG. May be at the end (see FIG. 7). Furthermore, the film 2 is not on 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 with a normal heat sealer.
As shown in FIG. 2 by a chain line 1a, is formed into a long piece in the shape of a piece,
A large number of packages 16 may be formed in a factory by a dedicated packaging machine that sequentially packages the products 9 while feeding the products. In the case of frozen foods, the package 16 may not be cut off at the seal 14 part, but may instead be perforated so that the consumer can cut it one by one and use it. Wrap multiple bags with exterior materials,
Similarly, one bag may be taken out and used.

The objects to be packaged include, in addition to the above-mentioned prepared foods, meat, fishery products (frozen fish, etc.), processed foods, etc. In the case of meat, sheets 3, 3 are used.
Partial waterproofing is preferable, and in the case of marine products, it is possible to use water supply paper together.

Furthermore, the strength of the sheets 3 and 3 can be increased by subjecting the sheets 3 and 3 to folding line processing (embossing) in the longitudinal direction thereof.

[0021]

As described above, according to the present invention, a film having high transparency is provided in the middle portion, and ventilation and
Packing products such as prepared foods with a packaging material that joins sheets that are rich in water absorption and water / oil resistance, the above-mentioned sheets share the role of dishes and the film shares the role of windows for product confirmation. As a result, consumers can see the entire product inside through the film and can take it with them at the time of purchase, which is convenient and does not change from the packaging using a conventional tray. Sometimes the product can be easily taken out simply by peeling off the film, and after taking out the sheet part becomes a plate, and since there is no tray, the amount of dust is small and the processing is easy.

If a material having heat resistance is used for the film and the sheet, it can be heated (or thawed) in the electronic cooker while being packaged, and it can be handled with high safety and is compatible with the electronic cooker. A packaging body that can be easily made can be obtained. Furthermore, by using a film that has been subjected to anti-fog treatment, it is possible to prevent the film from becoming cloudy and difficult to see even when warm side dishes are packed.
