Description

Packing sheet, packed rice ball, and a method of unpacking the same

The present invention relates to a packaging sheet formed by sandwiching a sheet-type food between films, a packaged rice lump in which a rice lump is packaged with the packaging sheet, and a method of unpacking the same, and more particularly, to maintain the dry state of the sheet-type food product It relates to a packaging sheet that can be used.

So-called packaged rice balls are sold at convenience stores, etc., in which lumps of rice, such as triangular rice balls, are packaged in a sheet-type packing sheet with embedded seaweed.

As the packaging sheet, a packaging sheet having a triple structure formed by sandwiching a sheet-like seaweed between an outer film and an inner film is widely known. For example, in Patent Document 1, a packaging sheet is formed by placing a sheet-like food product on the inner surface of an outer film having a splittable portion for segmenting in the longitudinal direction at a central portion in the width direction, and comprising two longitudinally long inner film pieces. The films are arranged so as to overlap on the inner end side, and the outer film and the inner film are thermally welded to be integrated.

Japanese Patent Laid-Open No. 2002-159271

The packaging sheet of Patent Document 1 has a configuration in which the inner film piece only overlaps the inner end portions so that the inner film facing the lump of rice can be divided. Therefore, moisture, moisture, etc. penetrates from the overlapping part, and the sheet-like steam which was in a dry state becomes wet. In particular, in the state in which the lump of rice is packed, the sheet-like laver becomes soggy in a very short time due to moisture or moisture coming out of the lump. Soggy sheet-type seaweed not only tastes bad, but also looks bad.

The present invention discloses a packaging sheet in which a sheet-type food product does not become soggy, a packaged rice mass obtained by packaging the rice mass with the packaging sheet, and a method of unpacking the same.

The packaging sheet of the present invention comprises:

A sheet food is placed on a film base in which the opposite ends of the first film and the second film are airtightly joined by a band-shaped cover piece, and the film base is folded in a direction orthogonal to the cover piece to be opened. It is made by heat-welding the three sides.

The said film base body is folded so that the said cover piece may oppose a sheet-like food product.

The film base has cutouts formed on both sides of the edge of the cover piece located on the outside when the lump of rice is packaged.

As for the said film base|substrate which was folded, heat welding for shift|offset|difference is given to one or more places around the said sheet-like food product.

In addition, the packaged rice mass of the present invention,

A packaged rice mass obtained by packaging a flat rice mass with the packaging sheet, wherein the cover piece is disposed on a bottom surface overlapping with a peripheral surface of the rice mass.

Further, in the method of unpacking the packaged rice mass of the present invention, with respect to the packaged rice mass, hold the end edge of the cover piece located on the outside, and fold the film body in the direction in which the cover piece moves away from the bottom surface. After dividing the film substrate located on the outside, hold it in a direction approximately parallel to the bottom surface, a direction inclined in an approximately parallel plane, the direction of the top of the lump of rice, or any one of the left and right directions By pulling, the cover piece existing between the lump of rice and the sheet-like food is taken out, and the film base is divided into the first film and the second film, and between the first film and the second film by division. With the formed dividing portion facing down, the lump of rice pulls out the sheet-like food from between the first film and the second film, and the package is unpacked by taking out the lump of rice wrapped in the sheet-like food.

As for the film base body, the connection part of a 1st film and a 2nd film is airtightly hold|maintained by the cover piece. Accordingly, intrusion of moisture or moisture from the connecting portion of the first film and the second film is prevented.

In addition, the packaging sheet folded by sandwiching the sheet-type food in the film base is airtight because the first film and the second film are continuous on one folded side, and the remaining three sides are airtightly heat-sealed, so moisture or moisture intrusion. Therefore, ingress of moisture or moisture in the manufacturing and conveying process of the packaging sheet is eliminated, and even in a state in which the rice lump is packaged, the inner surface of the packaging sheet in contact with the rice lump is the connection between the first film and the second film. The part is airtightly held by the cover piece. For this reason, the packaged rice mass packaged with the packaging sheet of this invention can prevent the penetration|invasion of the moisture and moisture coming out from a rice mass, and can maintain the dry state of a sheet-like food product.

In order to unpack the packaged rice mass packaged with the packaging sheet of this invention, what is necessary is just to divide the 1st film and 2nd film joined by the cover piece by removing the cover piece. The cover piece is arrange|positioned not only to the outer surface side of a sheet-form food product, but also to the inner surface side of a sheet-form food product like the prior art. Therefore, when pulling the cover piece on the inner surface side of the sheet-like food, in a direction substantially parallel to the bottom surface of the lump of rice, a direction inclined in a substantially parallel plane, in the direction of the top of the lump, or in any one of the left and right directions. pull with Thereby, as a result of peeling a cover piece from a 1st film and a 2nd film, a 1st film and a 2nd film are parted. And, by lowering the dividing portion formed between the first film and the second film, the lump of rice can take out the sheet-like food from between the first film and the second film, and the lump of rice wrapped in the sheet-like food can be taken out. Also, the lump of rice can be easily taken out by its own weight or by holding the end of the packaging sheet facing the divided portion and shaking it lightly. To some extent, when a lump of rice wrapped in a sheet-like food is exposed, if the exposed portion is grasped and pulled, the lump of rice wrapped in the sheet-like food can be more easily taken out. The taken out lump of rice is wrapped in a dry sheet food, so you can eat it as it is.

EMBODIMENT OF THE INVENTION Hereinafter, this invention is demonstrated, referring drawings. In addition, in order to make description easy to understand, drawing, especially sectional drawing, exaggerated, abbreviate|omitted, or schematically shows the width|variety, length, thickness, and welding shape of a film etc.

As shown in Figs. 1 to 3 , the film base 11 constituting the packaging sheet 10 includes two films composed of a first film 20 and a second film 30, a narrow cover piece. It is configured by airtightly connecting to (40). The first film 20 and the second film 30 may be transparent, translucent, or opaque films. Examples of this type of film include materials with low water permeability, such as polypropylene (PP), a biaxially stretched film (OP) made from polypropylene as a raw material, and a film in which Japanese paper or the like is laminated with polypropylene.

Each of the first film 20 and the second film 30 has a substantially rectangular shape, and in the illustrated embodiment, one side of the upper first film 20 and the lower second film 30 each opposing each other are arranged close to each other (reference numeral 17 in the figure), and the film base 11 airtightly connected with the cover piece 40 is constituted.

When the first film 20 and the second film 30 are folded into the form of the packaging sheet 10, the sheet-like food 50 can be accommodated, and the packaging sheet 10 is a lump of rice ( 60), a width and length that can wrap it is adopted.

In the illustrated embodiment, the first film 20 and the second film 30 have a width (up-down direction in FIG. 1 ) of 13 cm and a length (left-right direction in FIG. 1 ) of 32 cm.

The cover piece 40 which connects the 1st film 20 and the 2nd film 30 can be set as the film used as a cut tape, for example, The 1st film 20 and the 1st film 20 and The connection portion 17 of the second film 30 is hermetically bonded. In the illustrated embodiment, the cover piece 40 has a width of 5 mm and a length of 32 cm. As the cover piece 40, the film which gave the partial coating process which apply|coated the thermal adhesive to the bonding part of the 1st film 20 and the 2nd film 30 can be illustrated.

The film base 11 continuously cuts a film wound on a roll into, for example, the first film 20 and the second film 30, and the cover piece 40 is separated from the first film ( 20) and the second film 30 may be manufactured by attaching them to each other. And what is necessary is just to cut it to the required length suitably.

Moreover, the film base 11 is cut in the 1st film 20 and the 2nd film 30 so that one end edge of the cover piece 40 may be pinched|interposed, as shown in FIG.1, FIG.2. It is preferable to form the mouths 12 , 12 . The cutouts 12 and 12 are for the user to easily cut the film base 11 by holding the cover piece 40 between the cutouts 12 and 12 serving as the division start end when unpacking.

The film base 11 is folded so that the cover piece 40 is located on the inside at the inward fold line L1 of FIG. 1 and the outward fold line L2 of FIG. 2 that are substantially orthogonal to the cover piece 40. all. It is suitable for a folding position to make it into the longitudinal direction center of the film base|substrate 11. And as shown in FIGS. 4-6, the sheet food 50 is pinched|interposed between the folded film bases 11. As shown in FIG. In addition, after putting the sheet-like food product 50 on the film base 11, you may fold the film base 11.

In the above, the film base 11 is folded so that the cover piece 40 is located inside. Although this reason is demonstrated in the order of unpacking, this invention is not limited to being located inside the cover piece 40, It also includes folding so that it may be located outside.

The sheet-like food 50 can be exemplified by sheet-like laver. Although the sheet-like food 50 has shown a substantially rectangular thing, the thing of the shape in which the rectangular edge part was chamfered can also be used, or the thing of the shape in which the edge part in the longitudinal direction was roundly chamfered can also be used. In the illustrated embodiment, the sheet food 50 has a length in the longitudinal direction of about 18 cm and a length of about 9 cm in the width direction. The sheet food 50 is not limited to sheet-shaped laver, and if it is a thin food, a thinly pressed dried squid, a kelp formed in a sheet form, a soybean processed in a sheet form, etc. may be employed.

In the state which pinched|interposed the sheet-form food 50 in the folded film base 11, the film base 11 has one folded side and three open sides. The three open sides are subjected to linear thermal welding 13 as shown in Figs. 4 to 6 . Thereby, the film base 11 becomes the packaging sheet 10 which airtightly accommodated the sheet-like food product 50 by the one folded side and the three sides to which the heat welding 13 was performed. When the cutouts 12 and 12 described above are formed in the film base 11, in order to prevent penetration of moisture or the like from the cutouts 12 and 12, the thermal welding 13 is 12, 12), it is preferable to carry out on the inner side.

In addition, in the packaging sheet 10, in order to position the sheet-shaped food product 50 and suppress a shift, as shown in Fig. 4, one or more points surrounding the sheet-shaped food product 50 are formed in a dotted shape or a short linear shape. It is appropriate to perform thermal welding 14 .

As for the obtained packaging sheet 10, the connection part 17 of the 1st film 20 and the 2nd film 30 is sealed airtightly by the cover piece 40, and the peripheral edge is folded The sheet-like food 50 is accommodated by one folded side and three sides sealed airtightly by the heat welding 13 . Accordingly, it is possible to almost completely prevent intrusion of moisture, moisture, etc. into the inside of the packaging sheet 10 , and it is possible to properly maintain the dried state of the accommodated sheet-like food 50 over a long period of time.

The lump of rice 60 is packaged by the packaging sheet 10 . The lump of rice 60 can be made into one lump in a flat shape or a spherical shape by hardening white rice, mixed rice, or the like. The rice mass 60 may be partially or wholly sprinkled with powdered food such as sesame seeds, put on a filling material, or sandwiched with an ingredient material inside. In this embodiment, although the rice ball 60 is a triangular flat-shaped rice ball, it can also be set as a circular flat shape, a square flat shape, a circle|round|yen, a rectangle, and a cylindrical rice ball.

To package the lump of rice 60 , first, as shown in FIG. 4 , the lump of rice 60 is placed on the packaging sheet 10 . The position of the lump of rice 60 is approximately the center in the width direction of the packaging sheet 10, slightly above the cover piece 40, and when packaged, the circumferential surface (bottom surface) of the lump of rice 60 is the cover piece. (40) and the opposite position. Then, by wrapping the lump of rice 60 with the packaging sheet 10 so as to follow the circumferential surface of the lump of rice, and fixing the portion where the packaging sheet 10 overlaps with a fixing means 70 such as a tape, FIG. 7 ( The sheet-like food 50 is not shown) and, as shown in FIG. 8, a packaged rice mass 80 can be obtained. 9 : is the figure which looked at the packaged rice lump 80 from the bottom surface side where the cover piece 40 is located.

Although the fixing means 70 of this embodiment is a tape, it can also be fixed by using the label which described the manufacturing date, the content, etc., or by heat welding.

As described above, since the packaging sheet 10 airtightly accommodates the sheet-shaped food product 50 , the intrusion of moisture or moisture from the rice mass 60 can be prevented, and the sheet-shaped food product 50 is in a dry state. can be properly maintained.

First, between the cutouts 12 and 12 shown in Figs. 7 and 9 is held together with the cover piece 40, and it is pulled in the direction of the arrow E in Fig. 10 away from the bottom surface of the packaged rice mass 80. Thereby, the film base 11 is divided from the cutouts 12 and 12 by the cover piece 40 . Since the cover piece 40 is arrange|positioned on the inner surface side used as the sheet-like food 50 side with respect to the film base 11, similarly to a cut tape, the cover piece 40 is a film, as shown in FIG. While tearing off the first film 20 and the second film 30 of the base 11 , a wide dividing portion 15 is formed. By forming the wide parting part 15, the process of taking out the lump 60 and the sheet-like food 50 later WHEREIN: Resistance of a film can be made small.

Then, the cover piece 40 is pulled up to the portion where the film base 11, which is the end opposite to the cut-out portions 12 and 12, is folded (arrow (F) in Fig. 11), and the film base located on the outside ( 11) is divided. Then, as indicated by the arrows G(G', G") of FIG. 12 and the arrows H(H', H") of FIG. 13, with respect to the bottom surface of the packaged rice mass 80, approximately A parallel direction (G, H), or a direction inclined in a substantially parallel plane (G', H'), the direction of the top of the lump (G", H" toward the inside of the paper in FIGS. 12 and 13) , or, pull it in one of the left and right directions. Thereby, the cover piece 40 located inside the sheet-like food product 50 is taken out while peeling from the 1st film 20 and the 2nd film 30 which are the film base 11. As shown in FIG. As a result, the first film 20 and the second film 30 on the inner surface side, which were connected by the cover piece 40, are separated from each other, and a narrow dividing portion 16 is formed.

13 shows a state in which the cover piece 40 is completely pulled out, wherein the film base 11 has a divided portion 15 with a wider width on the outside and a divided portion with a narrower inner width than the sheet food 50 ( 16) is completely divided.

Then, by turning the divided portions 15 and 16 of the packaged rice mass 80 downward, as shown in FIGS. 14 and 15 , the rice mass 60 is either by its own weight or the divided portions 15 , 16) and by holding the end of the packaging sheet 10 opposite to and shaking lightly, it can be easily taken out in a state wrapped in the sheet-like food (50). At this time, as the lump of rice 60 is taken out, the film base 11 is opened with the dividing portions 15 and 16 wider and opened, and the lump 60 wrapped in the sheet-like food 50 in a dry state. ) can be obtained.

In addition, when the lump of rice 60 wrapped in the sheet-like food 50 is exposed to some extent, if the exposed portion is pulled, the lump of rice 60 wrapped in the sheet-like food 50 can be more easily taken out.

The taken out lump of rice is wrapped in a sheet-like food in a dry state, so you can eat it as it is.
