Description

  The present invention relates to a packaging sheet that can be formed by sandwiching a sheet-like food between an inner film and an outer film, and can package a rice lump, a packaged rice lump in which a rice lump is packaged with a packaging sheet, and a packaged rice lump. It is related with the method of unpacking.

  As a packaging sheet for rice balls sold at convenience stores and the like, a triple-structured sheet formed by sandwiching a sheet-like seaweed between an outer film and an inner film is widely known.

  The outer film has an outer severable portion such as a cut tape for dividing the outer film at the center in the width direction, and the inner film is composed of two film pieces. The two inner films are heat-welded to the outer film such that the inner ends of the film pieces overlap on the outer part of the outer film that can be separated (see, for example, Patent Document 1).

  The packaged rice cake in which the packaged rice cake is packaged by the packaging sheet is divided into two parts by the outer severable portion, and the inner film thermally welded to the outer film by pulling one of the separated outer films outward. One film piece is pulled out together.

  Subsequently, by pulling the other outer film to the outside and pulling it out together with the film pieces of the remaining inner film, it is possible to obtain a rice cake on which the sheet-like food is wound directly, and eat this .

Japanese Patent Laid-Open No. 2002-101832

  The inner film is simply a stack of the inner ends of the film pieces. Therefore, when a mass of rice containing a lot of moisture is packaged, the moisture enters the packaging sheet from the overlapping portion of the film pieces, and the sheet-like food May become damp, resulting in poor texture.

  An object of the present invention is to provide a packaging sheet in which a sheet-like food is not moistened even when a lump of rice is packaged.

The packaging sheet 1 according to the present invention is:
Sheet food 4 is sandwiched between the outer film 2 and the inner film 3 disposed on the back side of the outer film 2, and the outer film 2 and the inner film 3 are welded on the outer periphery of the sheet food 4. An integrated packaging sheet,
The outer film 2 has an outer severable portion 21;
The inner film 3 has an intermittent cut 31 formed at a position substantially opposite to the outer splittable portion 21, and a narrow cover film piece 32 is attached so as to cover the intermittent cut 31. It becomes.

  The cover film piece 32 can be attached to the inner film 3 by bonding or heat welding 33 along the intermittent cut 31 on one side.

  The cover film piece 32 is preferably attached to the sheet-like food 4 side of the inner film 3.

  Moreover, the packaged rice lump of the present invention is formed by packaging the lump 5 with the packaging sheet 1 described above.

In addition, the method of unwrapping the packaged rice lump of the present invention,
A method for unwrapping the packaged rice cake,
Dividing the outer film 2 into two outer film pieces 2a, 2b by the outer dividing portion 21,
By gripping one outer film piece 2b from above the lump 5 and pulling the other outer film piece 2a, the inner film 3 is connected to the intermittent cuts 31 so that two inner film pieces are connected. 3a and 3b, the inner film piece 3a facing the other outer film piece 2a is removed leaving the rice cake 5 and the sheet-like food 4,
The exposed sheet-like food 4 is gripped from the top of the rice lump 5, and the remaining outer film piece 2b and inner film piece 3b are removed.

  The packaging sheet 1 according to the present invention is provided with an intermittent cut 31 at a position substantially opposite to the outer severable portion 21 of the outer film 2 with respect to the inner film 3, and a cover film piece 32 covering this is mounted Yes. Therefore, since the intermittent cut 31 is covered with the cover film piece 32, the packaging sheet 1 does not allow moisture to enter the sheet-like food 4 accommodated from the inner film 3. For this reason, the dry state of the sheet-like food 4 can be maintained over a long time.

  Moreover, since the intermittent cut 31 of the inner film 3 is covered with the cover film piece 32, the moisture contained in the rice lump 5 is contained in the sheet-like food 4 in the packaged rice lump 6 wrapped by the packaging sheet 1. Can be prevented from entering the side. Therefore, the dry state of the sheet-like food 4 can be maintained for a long time, the appearance after unpacking is good, and the texture is excellent.

  Further, when the packaged rice lump 6 of the present invention is unpacked and the outer film 2 is pulled, the inner film 3 is divided into two inner film pieces 3a and 3b by connecting intermittent cuts 31 to each other. Therefore, the packaging can be easily unwound.

FIG. 10 is a perspective view of a packaged rice cake obtained by packaging a rice cake with the packaging sheet formed in the bag shape of FIG. 9.

  Hereinafter, with reference to the drawings, a packaging sheet 1 of the present invention and a packaged rice cake 6 obtained by packaging the rice cake 5 with the packaging sheet 1 will be described.

  As shown in FIGS. 1 to 3, the packaging sheet 1 of the present invention is configured by stacking an outer film 2, a sheet-like food 4, and an inner film 3. As shown in FIGS. 2 and 3, the outer film 2 and the inner film 3 are integrated by applying a thermal welding 11 to the periphery of the sheet-like food 4.

  The outer film 2 and the inner film 3 can be rectangular. In the illustrated embodiment, the outer film 2 and the inner film 3 are rectangular films having a length of about 27 cm and a width of about 16 cm. In addition, the outer film 2 and the inner film 3 can also be made into the polygonal shape which dropped the corner | angular part. Further, the size is not limited to the above.

  The outer film 2 has an outer severable portion 21 that can tear the outer film 2 in the direction over the entire length or the entire width. The outer severable portion 21 can be formed at the approximate center in the width direction or longitudinal direction of the outer film 2 or can be formed at a position shifted from the center. In the illustrated embodiment, the outer severable portion 21 is formed over the entire length of the outer film 2 at approximately the center in the width direction of the outer film 2.

  The outer part possible part 21 can illustrate the structure which sticks the cut tape 22 on the inner surface side (sheet-like foodstuff 4 side) of the outer film 2. FIG. In this case, it is desirable that the outer film 2 has a pair of outer cutting start portions 23 and 23 formed on the end edge with one end of the cut tape 22 interposed therebetween. The outer cutting start portions 23 and 23 are short cuts in the illustrated embodiment, and as shown in FIG. 5 described later, the outer cutting start portions 23 and 23 are formed at the end on the winding end side.

  Although not shown in the figure as the separable portion 21, a configuration in which the outer film 2 is intermittently perforated can be exemplified. In this case, in order to prevent moisture and the like from entering from the cut, it is desirable to arrange a narrow cover film piece on the inner surface of the outer film 20 along the cut.

  The inner film 3 can be a film having substantially the same shape as the outer film 2 as shown in FIG. 1 to FIG. Is preferred.

  On the inner film 3, intermittent slits 31 are formed at positions substantially opposite to the outer severable portion 21 of the outer film 2. The intermittent cut 31 is cut when the inner film 3 is pulled in a direction substantially perpendicular to the cut 31 and the cuts 31 are connected to each other and the inner film 3 is divided into two inner film pieces 3a and 3b. Form at possible intervals. Desirably, the length of each cut 31 is 0.5 mm to 5 mm, and the interval between the cuts 31 is 0.1 mm to 2 mm. If the cut line 31 becomes long, the strength of the inner film 3 may be reduced. Further, when the lump 5 is packaged, the cut line 31 may be opened at the bent portion of the inner film 3. Moreover, when the space | interval of the cuts 31 becomes long, there exists a possibility that the inner film 3 cannot be divided easily.

  The intermittent cut 31 is closed by a narrow cover film piece 32. As shown in the drawing, the cover film piece 32 is joined to the inner film 3 at one side along the intermittent cut 31 by heat welding 33 or adhesion. The cover film piece 32 can be about 1 cm to 2 cm in width.

  In addition, the cover film piece 32 is attached to the sheet-like food 4 side of the inner film 3 in order to avoid the resistance when the lump 5 is attached and unwraps.

  The sheet-like food 4 can illustrate sheet-like nori. The sheet-like food 4 is placed substantially at the center on the back side of the outer film 2. As the sheet-like food 4, a substantially rectangular shape can be used, 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 length of the sheet-like food in the longitudinal direction is about 19 cm, and the length in the width direction is about 10 cm.

  The sheet-like food 4 is not limited to the sheet-like seaweed, and if it is a thin food, it is possible to adopt a thinly stretched cocoon or a piece of rag kombu formed into a sheet.

  As shown in FIG. 1, the outer film 2, the sheet-like food 4, and the inner film 3 are placed on the sheet-like food 4 at the approximate center on the back side of the outer film 2, and the inner film 3 is stacked on top of the sheet-like food 4. As shown in FIG. 2 and FIG. 3, the outer sheet 2 and the inner film 3 are linearly heat-welded 11 so as to surround the sheet-like food 4, thereby producing the packaging sheet 1. It should be noted that it is desirable not to apply the heat welding 11 to the separable portion 21 and the cover film piece 32.

  Further, in order to prevent the sheet-like food 4 from shifting in the packaging sheet 1, as shown in FIG. 2, as shown in FIG. In the vicinity of one end or both ends in the longitudinal direction of the strip-shaped food 4, it is desirable to apply a point or short-line heat welding 13 at one or a plurality of locations.

  In the produced packaging sheet 1, the inner film 3 is composed of a single film, and the intermittent cuts 31 that are formed are also covered with the cover film piece 32. Intrusion of moisture and the like can be prevented almost completely, and the dry state of the stored sheet-like food 4 can be suitably maintained over a long period of time.

  The rice lump 5 packaged by the packaging sheet 1 can be made into a flat or spherical lump, or a columnar or prismatic rod-shaped boiled rice lump, such as white rice or savory rice. The rice lump 5 may be sprinkled with a sprinkled food such as sesame, partially or entirely, or the ingredients may be sandwiched inside. In this embodiment, the rice chunk 5 is a triangular flat-shaped rice ball, but it can also be a round rice ball or a rectangular rice ball.

The lump 5 is packaged by the packaging sheet 1 having the above configuration.
As shown in FIG. 2, the packaging places the lump 5 on the packaging sheet 1 with the inner film 3 side facing upward. The position of the rice lump 5 is approximately the center in the width direction of the packaging sheet 1 and is slightly above the longitudinal direction. Next, as shown by the arrow B in FIG. 2, the packaging sheet 1 is covered so as to wrap the rice chunk 5. Then, as shown in FIG. 4, the rice cake 5 is wrapped with the packaging sheet 1 along the circumferential surface of the rice cake, and the overlapping portion of the packaging sheet 1 is stopped by the fastening means 7 such as a tape, whereby the packaging rice cake 6 can be obtained.

  The fastening means 7 of the present embodiment is a tape, but it can also be fastened by using a label that describes the date of manufacture, contents, etc., or by thermal welding.

  In addition, as shown in FIG. 4, the corner | angular parts 15a and 15b which protruded from two vertices of the triangle of the packaged rice lump 6 are bent upward, and are stopped by fastening means 72 such as tape, so that the packaged rice lump is displayed at the time of display. The sitting of 6 can be improved. On the fastening means 72 or the bent corners 15 a and 15 b, marks such as an arrow or a sequence indicating the packaging procedure of the packaged rice lump 6 can be printed. The mark indicating the packaging procedure is given a numeral “2” indicating the pulling direction and order on one corner 15a when the cut by the outer severable portion 21 described later is “1”. Furthermore, it is preferable that the other corner portion 15b is also given a numeral “3” (not shown) indicating its pulling direction and order.

  FIG. 5 is a perspective view of a packaged rice cake 6 obtained by packaging the rice cake 5 with the packaging sheet 1 of the present invention. In the packaged rice lump 6, the inner film 3 is composed of a single film, and the formed intermittent cut 31 is closed with a cover film piece 32, and the overlap of the two film pieces is as before. Therefore, the intrusion of moisture or the like can be prevented, and the dry state of the stored sheet-like food 4 can be suitably maintained. In particular, in the packaged state, the moisture of the rice lump 5 does not pass through the inner film 3, so that the dry state of the sheet-like food 4 can be suitably maintained over a long period of time.

The packaged rice lump 6 can be unpacked in the following procedure.
First, as shown in FIG. 6, the outer severable portion 21 on the winding end side of the outer film 2 is picked and pulled in the direction of arrow C. Thereby, the outer film 2 is divided into two outer film pieces 2a and 2b. Also, before and after the division of the outer film 2, the fastening means 72 and 72 located on the left and right are peeled off to raise the corners 15a and 15b in the direction of arrow D, respectively. In the present embodiment, since the division of the outer film 2 is in the order “1”, the outer film 2 is divided first.

  Subsequently, as shown by an arrow E in FIG. 7, the corner portion 15a raised by the other outer film piece 2a is pulled while grasping the rice lump 5 from above the divided one outer film piece 2b. The corner portion 15a is given the order “2”. Thereby, the outer film 2 is removed together with the inner film piece 3a as described below, and the outer film piece 2b and the inner film piece 3b remain in the sheet-like food 4 and the rice lump 5. Become.

  In the above, by pulling the corner 15a of the outer film piece 2a, the inner film 3 is pulled with a force in a substantially vertical direction with respect to the intermittent cut 31, so that the intermittent cuts 31 are connected to each other. The inner film 3 is divided into inner film pieces 3a and 3b.

  Then, the divided inner film piece 3a is removed together with the outer film piece 2a.

  Finally, the rice cake 5 is grasped from above the exposed sheet-like food 4 and the corner portion 15b with the order "3" is picked, and the remaining outer film piece 2b and inner film piece 3b are moved to the arrow F in FIG. By pulling and removing as shown in, a lump of rice 5 wrapped in the sheet-like food 4 can be obtained.

  As described above, the packaged rice lump 6 of the present invention simply pulls the outer film 2, and the intermittent cuts 31 of the inner film 3 are connected to each other, thereby dividing the inner film 3 into the inner film pieces 3a and 3b. Therefore, the package of the rice lump 5 can be easily unpacked.

  The above embodiment is for explaining the present invention, and should not be construed as limiting the invention described in the claims or reducing the scope thereof. Moreover, each part structure of this invention is not restricted to the said one Embodiment, Of course, a various deformation | transformation is possible within the technical scope as described in a claim.

  In the above embodiment, packaging is performed so as to wrap the rice cake 5 with the packaging sheet 1, but as shown in FIG. 9, the packaging sheet 1 may be formed in a bag shape in advance.

  FIG. 9 is a perspective view of the bag-shaped packaging sheet 1. As shown in FIG. 9, the packaging sheet 1 is folded so that the upper edge is opened, and the collar portion is heat-sealed 14 to form a bag shape. It is formed. As shown in FIG. 9, it is desirable to form the collar portion so that the side close to the bottom is folded inward. Thereby, when it is set as a bag shape, it can prevent effectively that a foreign material, a water | moisture content, etc. penetrate | invade.
