JP 2002-159271 A

  The packaging sheet of Patent Document 1 has a configuration in which two inner film pieces are simply overlapped with each other in order to be able to divide the inner film facing the rice cake. Therefore, moisture, moisture and the like enter from the overlapped portion, and the sheet-like seaweed that has been in a dry state becomes wet. In particular, in the state where the rice cake is packaged, the sheet-like seaweed gets wet in a very short time due to moisture and moisture coming out of the rice cake. Moist sheet-like seaweed not only has a bad texture, but also looks bad. In addition, the wet sheet-like food may stick to the packaging sheet and break when unpacking.

  The present invention clarifies a packaging sheet in which a sheet-like food does not get wet, and a packaged rice cake obtained by packaging a rice cake with this packaging sheet.

The packaging sheet of the present invention is
A film base comprising: a first film; a second film; and a strip-shaped cover piece that airtightly joins the opposing edges of the first film and the second film, and the longitudinal direction of the cover piece A film substrate having a bent portion orthogonal to the cover piece at a substantially central position of
A sheet-like food sandwiched between the film substrates that are bent at the bent portion; and
A heat welding part for airtightly bonding three sides other than the bent part of the film base;
Have
In the first film and the second film, an easily breakable portion that easily breaks the first film and the second film is formed at a joint portion with the cover piece located inside when the rice lump is packaged. Has been.

  The easily breakable portion may be a plurality of cuts formed in the joint portion.

  It is desirable that the notch reaches the edge of the first film and the second film.

  The incisions may be formed at intervals along the edges of the first film and the second film.

  It is desirable that the film base has a bent portion in which the cover piece is bent toward the inner surface facing the sheet-like food.

  It can join with the said cover piece at intervals between the said one end edges which the said 1st film and the said 2nd film oppose.

The packaged rice lump of the present invention is
A flat-shaped rice lump is packaged by the packaging sheet described above.

In the above packaging sheet,
A cover film that is parallel to the cover piece and protrudes from both sides of the second film can be bonded to the second film at a portion that becomes an inner side when the lump of rice is packaged.

Moreover, the stick-shaped packaged rice lump of the present invention is
A rod-shaped rice lump is packaged by the packaging sheet described above.

  The film base is airtightly joined to the joining portion of the first film and the second film by a cover piece. Therefore, the penetration | invasion of the water | moisture content and moisture from the connection part of a 1st film and a 2nd film can be prevented.

  In addition, the packaging sheet folded with the sheet-like food sandwiched between the film base is airtight because the folded side is continuous with the first film and the second film, and the remaining three sides are airtightly heat-sealed. Intrusion of moisture and moisture is prevented. Therefore, intrusion of moisture and moisture only during the manufacturing and transporting process of the packaging sheet is eliminated, and the inner surface of the packaging sheet that comes into contact with the rice cake is connected to the first film and the second film even when the rice cake is packaged. The mating part is kept airtight by the cover piece. For this reason, the packaged rice lump in which a flat shaped rice lump or a rod-shaped rice lump is wrapped with the packaging sheet of the present invention can prevent the intrusion of moisture and moisture from the lump and maintain the dry state of the sheet-like food. Can do.

  In order to unwrap the packaged rice lump, the first piece and the second film joined by the cover piece may be divided by removing the cover piece. Specifically, first, the cover piece positioned outside the sheet-like food is pulled. Thereby, as for a cover piece, the junction part of the 1st film and 2nd film which are located outside peels, and joining of a 1st film and a 2nd film is released. After pulling the cover piece to the bent portion of the film base to release the bonding between the first outer film and the second film, the cover piece is pulled substantially parallel to the direction away from the film base. Since the easily breakable portion is formed in the joint portion between the inner cover piece and the first film and the second film, the cover piece is formed by tearing the first film and the second film from the easily breakable portion. The second film can be pulled out while unbonding. Thereby, joining of the inner first film and the second film is also released.

  In the case of a packaged rice lump that wraps a flat shaped rice lump, the flat shaped lump does not allow the sheet-shaped food to be used by turning the cut formed between the first film and the second film divided downward. The rice lump in a state of being pulled out from between the first film and the second film and wrapped in the sheet-like food can be taken out. In addition, the rice lump can be taken out by its own weight or by gently shaking the end of the packaging sheet facing the cut end and gently shaking it. When the mass of rice wrapped in the sheet-like food is exposed to some extent, the mass of rice wrapped in the sheet-like food can be taken out better by grasping and pulling the exposed portion. Since the taken out lump is wrapped in a sheet-like food in a dry state, it can be eaten as it is.

  In the case of the packaged rice cake in which the rod-shaped rice cake is packaged, the sheet-like food can be exposed by unfolding the packaging sheet and pulling the first film. Then, the rod-shaped rice lump around which the sheet-like food is wound can be eaten by winding the exposed sheet-like food around the rod-shaped rice lump.

<First Embodiment>
A schematic configuration of the packaging sheet 10 of the present invention will be described. As shown in FIGS. 1 and 2, a film base 11 is formed in which a substantially rectangular first film 20 and second film 30 are hermetically connected by a cover piece 40. A sheet-like food 50 is placed on the film base 11, and the film base 11 is bent along a line L1 (FIG. 1) substantially perpendicular to the cover piece 40 to form a bent portion L3. The film base 11 other than the bent portion L3 The heat-sealed part 13 is formed by heat-welding the three open sides, and the packaging sheet 10 is created by sealing hermetically.

  And the rice lump 60 is mounted on the rice side area | region 18 of the obtained packaging sheet 10, and the rice lump 60 is packaged, and the packaged rice lump 80 is obtained. In the following description, the packaging sheet 10, the film base 11, the first film 20, the second film 30, and the cover located on the left side of the valley fold line L 1 in FIG. 1 and on the right side of the mountain fold line L 2 in FIG. The piece 40 is referred to as the rice-side region 18 (side facing the rice lump 60), and the right side of the valley fold line L1 in FIG. 1 and the left side of the mountain fold line L2 in FIG. The reverse side).

  In the present invention, the easily breakable portions 24 and 34 are formed in the joining portions 22a and 32a of the rice side region 18 for the joining portions 32 and 42 where the first film 20 and the second film 30 are joined to the cover piece 40. It is a feature. The easily breakable parts 24 and 34 are cuts as shown in FIG. 3, for example. When the cover piece 40 is pulled when unwrapping the packaged rice lump 80, the outer region 19 is separated from the first film 20 by the cover piece 40. The second film 30 is divided, and the joining portions 22a and 32a of the rice-side region 18 are pulled by the cover piece 40 and easily broken from the easily breakable portions 24 and 34 as starting points.

  The present invention will be described below with reference to the drawings. In the drawings, particularly the cross-sectional views, the width, length, thickness, and welded shape of a film and the like are exaggerated, omitted, or schematically shown for easy understanding.

  As shown in FIGS. 1 and 2, the first film 20 and the second film 30 each have a substantially rectangular shape. In the illustrated embodiment, each of the upper first film 20 and the lower second film 30. The opposing sides are arranged close to each other. The first film 20 and the second film 30 can employ transparent, translucent or opaque films. Examples of this type of film include materials having low water permeability, such as polypropylene (PP), biaxially stretched film (OP) made of polypropylene, and films obtained by laminating Japanese paper with polypropylene.

  In the illustrated embodiment, the first film 20 and the second film 30 have a rectangular shape with a width (vertical direction in FIG. 1) of 13 cm and a length (horizontal direction of FIG. 1) of 32 cm. Is not limited to this.

  As shown in FIGS. 1 and 2, the film base 11 sandwiches one end edge of the cover piece 40 in the outer region 19 so that the user can easily grasp the cover piece 40 when opening the film base 11. The opening cuts 12 and 12 are preferably formed in the first film 20 and the second film 30. Thereby, when unpacking, the user can easily divide the film substrate 11 by grasping the cover piece 40 between the opening cuts 12 and 12 which becomes the dividing start end.

  In the first film 20 and the second film 30, easily breakable portions 24 and 34 are formed at the joining portions 22 a and 32 a of the rice-side region 18, respectively. As shown in FIGS. 1 and 2, the easily breakable portions 24 and 34 are formed in the rice-side region 18 of the joining portions 22 and 32 where the both films 20 and 30 are joined to the cover piece 40. The easily breakable portions 24 and 34 can be provided over the entire length of the joint portions 22 and 32.

  When the cover piece 40 is pulled, the easily breakable portions 24 and 34 are broken at the joint portions 22a and 32a together with the cover piece 40, and are guided or broken so that the first film 20 and the second film 30 can be easily divided. This is the starting point. For example, the easily breakable portions 24 and 34 are cuts formed at opposite edges of the films 20 and 30 as shown in the enlarged view 3. It is desirable to form the cut so as to reach the opposite edges of the first film 20 and the second film 30 as shown in the drawing so that the films 20 and 30 are easily torn. The easily breakable portions 24 and 34 are preferably 1 mm to 10 mm, and more preferably 3 mm to 5 mm. The easily breakable portions 24 and 34 can be equally spaced or can be provided at different intervals.

  The cover piece 40 joins the joining portions 22 and 32 of the first film 20 and the second film 30 together. The cover piece 40 can be a film used as a cut tape, for example. By joining the cover piece 40 to the joining portions 22 and 32 of the first film 20 and the second film 30 by adhesion or heat welding, the joining portion 17 of the films 20 and 30 is hermetically sealed. Is obtained.

  In the illustrated embodiment, the cover piece 40 has a width of 5 mm and a length of 32 cm. Examples of the cover piece 40 include a film obtained by applying a part coat process in which a heat-sensitive adhesive is applied to the joint portions 22 and 32 between the first film 20 and the second film 30. In addition, in this invention, since the easily breakable parts 24 and 34 are formed in the joining parts 22a and 32a of the rice side area | region 18, the division | segmentation of the 1st film 20 and the 2nd film 30 of the rice side area | region 18 is mentioned later. Can be easily performed. For this reason, the joining strength by part coat processing can be raised. Thereby, the airtightness of the film base | substrate 11 can be improved as much as possible.

  The above-described film base 11 is formed by, for example, continuously cutting a film wound on a roll into a first film 20 and a second film 30 and easily breaking into joint portions 22a and 32a of the rice-side region 18 on the downstream side. Cuts to become the parts 24 and 34 and opening cuts 12 and 12 are made. Further, on the downstream side, the cover piece 40 can be manufactured by joining the first film 20 and the second film 30 to the joining portions 22 and 32 and cutting them to the required length. Of course, the manufacturing method of the film base | substrate 11 is not limited to this.

  As shown in FIGS. 1, 2, and 4, the obtained film substrate 11 is bonded to the first film 20 and the second film 30 by the cover piece 40, and the bonding portions 22 and 32 are hermetically closed. It will be.

  The obtained film substrate 11 is folded to wrap the sheet-like food 50 as described below. The sheet-like food 50 is, for example, a sheet-like seaweed. The sheet-like food 50 is illustrated as having a substantially rectangular shape, but a rectangular shape with a chamfered corner or a shape with a rounded chamfered end in the longitudinal direction can also be used. . In the illustrated embodiment, the sheet-like food 50 has a length in the longitudinal direction of about 18 cm and a length in the width direction of about 9 cm. The sheet-like food 50 is not limited to the sheet-like seaweed, and if it is a thin food, a thinly stretched rice cake, a coconut-shaped kelp formed into a sheet, a soybean processed into a sheet, or the like is adopted. be able to.

  The film substrate 11 is folded at the center in the longitudinal direction (the valley fold line L1 in FIG. 1 and the mountain fold line L2 in FIG. 2) substantially orthogonal to the cover piece 40 to form a bent portion L3, and the sheet-like food 50 is interposed therebetween. Packaging. The film substrate 11 may be bent after the sheet-like food 50 is placed on the film substrate 11. Here, the film base 11 is bent so that the cover piece 40 faces the sheet-like food 50 at the valley fold line L1 of FIG. 1 and the mountain fold line L2 of FIG. . Although this reason is demonstrated in the procedure which unwraps, this invention is not limited to what is located inside, but includes what is bent so that it may be located outside.

  In a state where the sheet-like food 50 is sandwiched between the folded film base 11, the film base 11 has a bent portion L3 and three open sides. As shown in FIG. 5 to FIG. 7, on the three open sides, by forming a heat-welded portion subjected to linear heat-welding, a packaging sheet 10 in which the sheet-like food 50 is wrapped in an airtight manner is obtained. It is done.

  When the above-described opening cuts 12 and 12 are formed on the film base 11, the heat welding portion 13 is provided with an opening cut in order to prevent intrusion of moisture and the like from the opening cuts 12 and 12. It is desirable to apply inside 12 and 12.

  In order to position the sheet-like food 50 on the packaging sheet 10 and suppress the deviation, as shown in FIG. 5, one or a plurality of places surrounding the sheet-like food 50 are subjected to dot-like or short linear heat welding. It is desirable to form the heat welded part 14.

  The obtained packaging sheet 10 has the joint portion 17 of the first film 20 and the second film 30 hermetically closed by the cover piece 40 on both the inner surface side and the outer surface side, and the periphery is thermally welded to the bent portion L3. The sheet-like food 50 is accommodated by the three sides airtightly closed by the portion 13. Accordingly, it is possible to almost completely prevent moisture, moisture and the like from entering the inside of the packaging sheet 10, and the dry state of the stored sheet-like food 50 can be suitably maintained for a long time.

  The lump 60 is packaged by the packaging sheet 10. The rice lump 60 can be made into a lump having a flat shape or a spherical shape by hardening white rice or rice. The rice lump 60 may be partially or entirely sprinkled with sprinkled food such as sesame, placed with ingredients, or sandwiched with ingredients. In this embodiment, the rice cake 60 is a triangular flat rice ball, but it can also be a round flat shape, a square flat shape, a round shape, a square shape, or a bowl shape.

  As shown in FIG. 5, the rice lump 60 is placed and packaged in the rice-side region 18 of the packaging sheet 10. The position of the rice lump 60 is substantially the center in the width direction of the rice side region 18 of the packaging sheet 10 and is slightly above the cover piece 40, and when wrapped, the peripheral surface (bottom surface) of the rice lump 60 is the cover piece 40. And the position facing. And the rice lump 60 is wrapped with the packaging sheet 10 along the peripheral surface of the rice lump, and the overlapping portion of the packaging sheet 10 is stopped by the fastening means 90 such as tape, so that FIG. ) And cross-sectional view 9, a packaged rice lump 80 can be obtained. FIG. 8 is a view of the packaged rice lump 80 as viewed from the bottom side where the cover piece 40 is located.

  Although the fastening means 90 of this embodiment is a tape, it can also be fastened by using a label that describes the date of manufacture, contents, etc., or by thermal welding.

  As described above, the packaging sheet 10 contains the sheet-like food 50 in an airtight manner. Therefore, the packaged rice cake 80 obtained by packaging the rice cake 60 with the packaging sheet 10 can prevent moisture and moisture from entering from the outside. In addition, the rice-side region 18 of the film base 11 facing the lump 60 is not only simply overlapped with the inner films as in the prior art, but also the first film 20 and the second film 30 are joined airtightly by the cover piece 40. Therefore, intrusion of moisture and moisture from the rice lump 60 can be prevented. For this reason, the dry state of the sheet-like food 50 can be maintained suitably.

The packaged rice lump 80 can be unpacked in the following procedure.
FIG. 10 is a view of the packaged rice lump 80 as viewed from the bottom side. First, the gap between the opening cuts 12 and 12 shown in FIG. 10 is picked together with the cover piece 40 and pulled in the direction of arrow F away from the bottom surface of the packaged rice lump 80 as shown in FIG. Accordingly, the outer region 19 of the film base 11 is separated from the opening cuts 12 and 12 by the cover piece 40. Since the cover piece 40 is disposed on the inner surface side that is the sheet-like food 50 side with respect to the film base 11, the cover piece 40 is formed of a film as shown in FIGS. A wide cut 15 is formed while tearing the first film 20 and the second film 30 of the substrate 11. By forming the wide cut end 15, the resistance of the film can be reduced in the subsequent step of taking out the rice lump 60 and the sheet-like food 50.

  And the 1st film 20 located in the outer side area | region 19 is pulled by pulling the cover piece 40 to the bending part L3 of the film base | substrate 11 used as the edge part on the opposite side to the opening notches 12 and 12 (arrow G of FIG. 12). And the second film 30 is divided.

  Subsequently, the cover piece 40 is pulled in a direction H substantially parallel to the bottom surface of the packaged rice lump 80 as indicated by an arrow H in FIG. Thereby, the cover piece 40 of the rice-side area | region 18 is fractured | ruptured from the easily breakable parts 24 and 34 formed in the joining parts 22a and 32a of the 1st film 20 and the 2nd film 30 of the rice-side area | region 18. . FIG. 14 shows a state in which the first film 20 and the second film 30 in the encircled portion I of FIG. FIG. 14 is a view of the rice area 18 viewed from the sheet-like food 50 side. As shown in FIG. 14, the first film 20 and the second film 30 are easily pulled when the cover pieces 40 are pulled in the direction of arrow H, so that the joint portions 22 a and 32 a joined to the cover pieces 40 are pulled. The cracks 25 and 35 extend from the fractured portions 24 and 34, and the first film 20 and the second film 30 are broken in the vicinity of the cover piece 40 by connecting the cracks 25 and 35.

  Further, by pulling the cover piece 40, the cracks 25 and 35 are completely connected as shown in FIG. 15, and the first film 20 and the second film 30 are completely broken.

  In FIGS. 14 and 15 and FIGS. 16 to 18 to be described next, the cracks 25 and 35 have substantially the same shape, but actually the cracks 25 and 35 are random starting from the easily breakable portions 24 and 34. Connected in a state.

  And as shown by the arrow J in FIG. 16, the 1st film 20 and the 2nd film 30 of the rice side area | region 18 which were joined by the cover piece 40 are completely parted by pulling out the cover piece 40 completely. A cut 16 is formed.

  FIG. 17 is a view of the rice-side region 18 of the encircled portion K in FIG. 16 as viewed from the sheet-like food 50 side. Referring to FIG. 17, it can be seen that the first film 20 and the second film 30 are completely broken by the cracks 25 and 35.

  FIG. 18 shows the cover piece 40 withdrawn on the side of the rice area 18. 18A is a view seen from the first film 20 and the second film 30 side, and FIG. 18B is a view seen from the cover piece 40 side. As shown in the figure, the broken pieces of the first film 20 and the second film 30 that remain are left on the cover piece 40.

  By the above, the 1st film 20 and the 2nd film 30 are parted completely, and the cut edges 15 and 16 are formed in the part parted. Then, by turning the cut ends 15 and 16 downward, as shown in FIGS. 19 and 20, the rice lump 60 grips the end portion of the packaging sheet 10 facing the cut ends 15 and 16 by its own weight. By gently shaking, it can be taken out in a state of being successfully wrapped in the sheet-like food 50. At this time, by pulling out the rice lump 60, the film base 11 can be opened with the cut ends 15 and 16 opened wider, and the lump 60 wrapped in the sheet-like food 50 in a dry state can be obtained. .

  In addition, if the rice lump 60 wrapped in the sheet-like food 50 is exposed to some extent, the rice lump 60 wrapped in the sheet-like food 50 can be taken out better by grasping and pulling the exposed portion.

  Since the taken out lump is wrapped in the sheet-like food 50 in a dry state, it can be eaten as it is.

  In the above embodiment, packaging is performed so as to wrap the rice cake 60 with the packaging sheet 10, but the rice cake 60 may be packaged with the bag-shaped packaging sheet 10 as shown in FIG. 21. In this case, the packaging sheet 10 may be formed in a bag shape in advance and the rice lump 60 may be input, or may be formed in a bag shape after the rice lump 60 is placed.
