[Patent Document 1] Japanese Patent Laid-Open Publication No. 2002-159271

In the packaging sheet of Patent Document 1, the inner film facing the rice block is set to be separable, and therefore the inner film sheet has a structure in which only the inner ends overlap each other. Therefore, moisture, moisture, and the like infiltrate from the overlapping portion thereof, so that the flaky seaweed in the dry state becomes moist. Particularly in the state in which the rice pieces are packaged, the flaky seaweed becomes moist with moisture in a very short time because moisture and moisture oozing out from the rice pieces. The flaky seaweed that becomes moist is not only bad in taste, but also unattractive.

The present invention relates to a packaging sheet in which a flaky food is not moisture-containing, a packaged rice cake in which the rice sheet is packaged by the packaging sheet, and a method of unwrapping the package.

In the packaging sheet of the present invention, a sheet-like food product is disposed in a film-like shape in which a film-like cover sheet is hermetically bonded to one end edge of the first film and the second film, and is oriented in a direction orthogonal to the cover sheet. The film substrate is bent and the open three sides are thermally welded.

The film-based system is bent such that the cover sheet faces the sheet-like food.

The film-based system is applied to both sides of the edge of the cover sheet located on the outer side when the rice block is packaged.

The bent film-based system is subjected to heat-sealing for preventing sliding at one or a plurality of portions around the sheet-like food.

Further, the packaged rice piece of the present invention is a packaged rice piece obtained by packaging a flat shaped rice piece by the packaging sheet, and the cover sheet is disposed on a bottom surface overlapping the circumferential surface of the rice piece.

Further, the method for unwrapping the packaged rice block of the present invention is to stretch the edge of the cover sheet located on the outer side of the packaged rice piece to the edge of the cover sheet and to stretch the film substrate In part, after the film substrate located on the outer side is divided, the film is pulled in such a manner that the bottom surface is inclined in a substantially parallel direction, in a direction substantially inclined in a substantially parallel plane, in a top direction of the rice block, or in either of the left and right directions. a cover sheet between the rice piece and the sheet-like food product, and the film substrate is divided into the first film and the second film, and is formed between the first film and the second film by division The incision is downward, and the rice piece is pulled out from between the first film and the second film in the sheet-like food, and the rice cake in a state of being wrapped in a sheet-like food is taken out and the package is released.

The film-based system hermetically maintains the bonded portion of the first film and the second film by the cover sheet. Thus, it can prevent moisture and moisture from the first The bonded portion of the film and the second film penetrates.

Further, the packaging sheet which is bent by sandwiching the sheet-like food product with the sheet-like food material is continuously airtight by the first film and the second film, and the remaining three sides are prevented from moisture by heat-sealing heat-sealing. And the infiltration of moisture. Therefore, the moisture and moisture of the packaging sheet are not infiltrated in the process of manufacturing and transporting, and the inner surface of the packaging sheet which abuts the rice cake is airtightly maintained by the cover sheet in the state in which the rice is packaged. a bonding portion of the film and the second film. Therefore, the packaged rice pieces packaged in the packaging sheet of the present invention can prevent the infiltration of moisture and moisture from the rice pieces, and can maintain the dry state of the flaky food.

When the package of the packaged rice wrapped in the packaging sheet of the present invention is unwound, the first film and the second film joined by the cover sheet may be divided so as to remove the cover sheet. The cover sheet is not disposed on the outer surface side of the sheet-like food as in the case of the outer side of the sheet-like food. Therefore, when the cover sheet on the inner surface side of the sheet-like food is opened, it is a direction substantially parallel to the bottom surface of the rice block, a direction inclined in a substantially parallel plane, a top direction of the rice block, or any one of the left and right directions. Pull open. Thereby, as a result of peeling off the cover sheet from the first film and the second film, the first film and the second film are divided. Further, by setting the slit formed between the first film and the second film downward, the sheet-like food can be pulled out from between the first film and the second film, and taken out and packaged. A piece of rice in the state of flaky food. Further, the rice pieces can be smoothly taken out of the rice pieces packaged into the flaky food by the weight of the rice itself or by gently shaking the ends of the packaging sheets facing the slits. When the rice pieces packed into flaky foods show some way At the time of the degree, if the exposed portion is stretched, the rice piece packaged into the flaky food can be taken out more smoothly. Since the taken rice block is packaged into a flaky food in a dry state, it can be eaten directly.

Hereinafter, the present invention will be described with reference to the drawings. In addition, in the drawings, in particular, in order to facilitate the description, the width, length, thickness, and weld shape of a film or the like are exaggerated, omitted, or schematically displayed.

As shown in FIGS. 1 to 3, the film substrate 11 constituting the packaging sheet 10 is formed by air-tightly bonding two films composed of the first film 20 and the second film 30 with a cover sheet 40 having a small width. The first film 20 and the second film 30 may be formed of a transparent, translucent or opaque film. Examples of such a film include a polypropylene (PP), a biaxially stretched film (OP) using polypropylene as a raw material, and a material having a low water permeability such as a film in which polypropylene and paper are stacked.

Each of the first film 20 and the second film 30 has a substantially rectangular shape. In the embodiment shown in the figure, the first film 20 on the upper side and the second film 30 on the lower side are disposed adjacent to each other (the symbol in the figure) 17) A film substrate 11 which is hermetically joined by the cover sheet 40 is formed.

When the first film 20 and the second film 30 are bent into the form of the packaging sheet 10, the sheet-shaped food 50 can be accommodated, and the package sheet 10 can be wrapped around the width and length of the rice block 60.

In the embodiment shown in the drawings, the width of the first film 20 and the second film 30 (the vertical direction in FIG. 1) is 13 cm, and the length (the horizontal direction in FIG. 1) is 32 cm.

In combination with the cover sheet 40 of the first film 20 and the second film 30, for example, a film used as a cut tape can be used, and the first film 20 and the second film 30 are hermetically joined by bonding or heat welding. The combination part 17. In the illustrated embodiment, the cover sheet 40 has a width of 5 mm and a length of 32 cm. As the cover sheet 40, a film which is subjected to a part-coated process in which a heat-sensitive adhesive is applied to a joint portion of the first film 20 and the second film 30 can be exemplified.

The film substrate 11 can be produced, for example, by continuously cutting the film wound on the roll into the first film 20 and the second film 30, and on the downstream side, the cover sheet 40 is attached to join the first film 20 and the first film. 2 film 30. Then, it is cut into a length that is appropriately necessary.

Further, as shown in FIGS. 1 and 2, the film base 11 preferably forms the cut portions 12 and 12 in the first film 20 and the second film 30 so as to sandwich the end edge of the cover sheet 40. The cut-in portions 12 and 12 are used for the user to pinch the cover sheet 40 between the cut-in portions 12 and 12 as the split start end when the package is unwound, so that the film base 11 can be easily divided.

The film substrate 11 is bent on the valley fold line L1 of FIG. 1 and the mountain fold line L2 of FIG. 2 which are substantially orthogonal to the cover sheet 40, and is bent into the cover sheet 40. side. The position of the bending is appropriate in the center in the longitudinal direction of the film substrate 11. Further, as shown in FIGS. 4 to 6, the sheet-like food product 50 is sandwiched between the bent film substrates 11. Further, the sheet-like food product 50 may be placed on the film substrate 11 and then the film substrate 11 may be bent.

In the above, the film substrate 11 is bent so that the cover sheet 40 is located inside. The reason for this will be described in the order in which the package is unwound, but the present invention is not limited to the case where the cover sheet 40 is located inside, and the case where the cover sheet 40 is bent to the outside.

The flaky food 50 can be exemplified by flaky seaweed. The sheet-like foods 50 are generally rectangular in shape, and the corners of the rectangular shape are formed by chamfering, and the end portions in the longitudinal direction may be curved by chamfering. In the illustrated embodiment, the sheet-like food product 50 has a length of about 18 cm in the longitudinal direction and a length of about 9 cm in the width direction. The flaky food 50 is not limited to the flaky seaweed, and may be used as long as it is a thin food, a dried squid is thinned, a kelp is formed into a flaky shape, and soybeans are processed into a flaky shape.

In a state in which the sheet-like food product 50 is sandwiched by the bent film substrate 11, the film substrate 11 has a bent side and an open three sides. As shown in FIGS. 4 to 6, a linear heat fusion 13 is applied to the three sides of the opening. Therefore, the film substrate 11 is a packaging sheet 10 in which the sheet-like food product 50 is hermetically accommodated by the bent side and the three sides of the heat-sealed metal 13 . In the case where the above-described cut-in portions 12 and 12 are formed in the film base 11, the heat-sealing 13 is preferably applied to the inner side of the cut-in portions 12 and 12 in order to prevent penetration of moisture or the like from the cut-in portions 12 and 12.

Further, in the packaging sheet 10, the sheet-like food product 50 is positioned, and in order to suppress the offset, as shown in FIG. 4, it is preferable to apply a spot-like or short-line heat-welding 14 to one or a plurality of portions of the sheet-like food product 50.

The obtained packaging sheet 10, the first film 20 on the inner side and the outer side, and the joint portion 17 of the second film 30 are hermetically sealed by the cover sheet 40, and the periphery is bent by the side and heated. The welded portion 13 is airtightly clogged to accommodate the sheet-like food 50. Therefore, it is almost completely prevented that moisture, moisture, or the like penetrate into the inside of the packaging sheet 10, and the dry state of the stored sheet-like food 50 can be favorably maintained over a long period of time.

The rice block 60 is packed by the above-described packaging sheet 10. The rice block 60 can be hardened into a flat shape or a spherical shape by kneading white rice or fried rice. The rice cake 60 may be partially or entirely sprinkled with sprinkled food such as sesame seeds or ingredients, or the ingredients may be sandwiched inside. The rice piece 60 in the present embodiment has a triangular flat shape rice ball, but may be a round flat shape, a quadrangular flat shape, a round shape, a square shape, or a cylindrical rice ball.

When the rice block 60 is packed, first, as shown in FIG. 4, the rice block 60 is placed on the packaging sheet 10. The position of the rice block 60 is located substantially at the center in the width direction of the packaging sheet 10, slightly above the cover sheet 40, and the circumferential surface (bottom surface) of the rice cake 60 after packaging is located opposite to the cover sheet 40. Further, the rice sheet 60 is wrapped around the circumferential surface of the rice pad with the packaging sheet 10, and the overlapping portion of the packaging sheet 10 is fixed by a fixing means 70 such as a tape, whereby, as shown in Fig. 7 (the sheet-like food 50 is not shown) As shown in Fig. 8, a packaged rice block 80 can be obtained. Fig. 9 is a view of the packaged rice block 80 as seen from the bottom surface side where the cover sheet 40 is located.

The fixing means 70 of the present embodiment is an adhesive tape, but may be fixed by a label or heat fusion which describes the date of manufacture, the contents, and the like.

As described above, since the packaging sheet 10 contains the sheet-like food product 50 in an airtight manner, it is possible to prevent the infiltration of moisture and moisture from the rice cake 60, and to maintain the dry state of the sheet-like food product 50 satisfactorily.

The packaged rice block 80 described above can be unpacked in the following order.

First, the cut portions 12 and 12 shown in Figs. 7 and 9 are pinched together with the cover sheet 40, and are stretched in the direction of the arrow E of Fig. 10 which is separated from the bottom surface of the packaged rice block 80. Thereby, the film substrate 11 is divided from the cut portions 12 and 12 by the cover sheet 40. Since the cover sheet 40 is disposed on the inner surface side which is the sheet-like food product 50 side on the film substrate 11, the cover sheet 40 is the first film 20 and the first film 20 of the film substrate 11 as shown in FIG. 2 The film 30 is torn to form a slit 15 having a wide width. Since the slit 15 having a wide width is formed, the resistance of the film can be made small in the following steps of taking out the rice cake 60 and the flaky food 50.

Then, the cover sheet 40 is pulled to the bent portion (the arrow F in FIG. 11) of the film base 11 which is the end portion on the opposite side to the cut portions 12 and 12, and the film base 11 located on the outer side is divided. Thereafter, as shown by an arrow G (G', G") of FIG. 12 and an arrow H (H', H" of FIG. 13, the bottom surface of the packaged rice block 80 is oriented in a substantially parallel direction (G, H). Or the direction (G', H') inclined in a substantially parallel plane, the top direction of the rice block ((G", H" toward the back side of the paper in Figs. 12, 13), or any of the left and right directions The film is placed on the inner side of the flaky food 50 from the film substrate 11, that is, the first film 20 and the second film 30. 40 peeled off and torn off. As a result, the first film 20 and the second film 30 on the inner surface side joined by the cover sheet 40 are unjoined and divided, and a slit 16 having a narrow width is formed.

Fig. 13 shows a state in which the cover sheet 40 is completely torn off, and the film base 11 is completely divided by the slit 15 having a wide outer side and the slit 16 having a narrow width closer to the inner side than the sheet-like food 50.

Next, in a manner such that the slits 15, 16 of the packaged rice block 80 are downward, as shown in Figs. 14 and 15, the rice block 60 is held by its own weight or by a sheet of packaging which is opposed to the slits 15, 16. The end portion of the 10 is gently shaken, and it can be smoothly taken out in a state of being packaged into the sheet-like food 50. At this time, since the rice pieces 60 are pulled out, the slits 15, 16 of the film substrate 11 are opened to have wider openings, and the rice pieces 60 of the sheet-like foods 50 packaged in a dry state can be obtained.

Further, when the rice piece 60 packaged in the sheet-like food product 50 is exposed to some extent, the rice piece 60 packaged into the sheet-like food product 50 can be taken out more smoothly if the exposed portion is stretched.

Since the taken rice block is packaged into a flaky food in a dry state, it can be eaten directly.

The above embodiments are intended to be illustrative of the present invention and should not be construed as limiting the scope of the invention or the scope of the invention. Further, the structure of each part of the present invention is not limited to the above-described one embodiment, and various modifications can of course be made within the technical scope described in the claims.

For example, the above embodiment is packaged by a packaging sheet 10, the rice block 60 is wrapped, but as shown in Fig. 16, the rice cake 60 can also be packed in a bag-shaped packaging sheet 10. In this case, the packaging sheet 10 may be formed into a bag shape before being placed in the rice block 60 or placed on the rice block 60, and then formed into a bag shape.

In the above description, the appropriate size and desired shape are exemplified for the sake of explanation, but the present invention is not limited to the above-described size and shape. For example, the size of the packaging sheet 10 may be made as long as it is the size of the rice piece 60 to be packaged.

Further, in the above embodiment, the opposite sides of the first film 20 and the second film 30 are brought close to each other and joined by the cover sheet 40, and as shown in Fig. 17, the opposite sides may be spaced apart from each other. . In this case, the cover sheet 40 may be used in a width corresponding to the width of the interval.

Fig. 17 shows a packaging sheet 10 in which the opposite sides of the first film 20 and the second film 30 are formed with a space S therebetween. By providing the space S between the first film 20 and the second film 30, the slits 15 and 16 (see FIG. 14 and the like) formed after the cover sheet 40 is removed can have a larger width, and thus can be easily taken out. Rice block 60. The interval S is preferably about 2 mm to 10 mm, and the maximum is the width of the rice block 60. In this case, in the cover sheet 40, the position indicated by the reference numeral 41 in the oblique line is added to FIG. 17, that is, the heat-sensitive adhesive is applied to the position where the cover sheet 40 and the first film 20 and the second film 30 overlap each other. The bonding agent or heat fusion can be used. The overlapping portion 41 of the first film 20, the second film 30, and the cover sheet 40 is preferably 2 mm to 5 mm, and preferably 2.5 mm to 3 mm.

Further, one of the opposing sides of the first film 20 and the second film 30 may be disposed such that their end edges overlap each other. In this case, The cover sheet 40 is only required to be disposed to hermetically join the two films along the edge of one of the films.

Further, as shown in Fig. 17, the linear heat fusion 13 applied to the open sides of the film substrate 11 is carried out so as to be recessed inside the portions of the cut portions 12 and 12 as indicated by reference numeral 13a. Thereby, the long cut portions 12 and 12 can be obtained, and when the package is unwound, the cut portions 12 and 12 can be easily pinched.
