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 is provided with a dividing guide band 31 parallel to the severable portion 21 at a position substantially opposite to the outer severable portion 21.

  The division guide band 31 can be a narrow band attached to the inner film 3 by adhesion or heat welding.

  The inner film 3 can be a directional film that tears along the longitudinal direction of the dividing guide band 31.

  In the inner film 3, it is desirable to form an inner dividing start portion 33 on either side of one end or both ends of the dividing guide band 31.

  The dividing guide band 31 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 grasping one outer film piece 2b from the top of the rice lump 5 and pulling the other outer film piece 2a, the inner film 3 crosses the dividing guide band 31 substantially along the dividing guide band 31. Without splitting into two inner film pieces 3a, 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,
Grabbing the exposed sheet-like food 4 from above the lump 5 and removing the remaining outer film piece 2b and inner film piece 3b,
Is.

  The packaging sheet 1 according to the present invention is provided with a dividing guide band 31 at a position substantially opposite to the outer dividing possible portion 21 of the outer film 2 with respect to the inner film 3. When the outer film 2 is pulled when unwrapping the packaged rice lump 6 packaged by the packaging sheet 1, the inner film 3 substantially extends along the dividing guide band 31, but the tear is spread without exceeding the dividing guide band 31. The film is divided into two inner film pieces 3a and 3b. Therefore, the inner film 3 can be composed of a single film, and the inner film 3 does not require intermittent cuts such as perforations. Since the inner film 3 can be composed of a single film, when the rice cake 5 is packaged with the packaging sheet 1, the sheet-like food 4 is moistened by steam from the rice cake 5 or moisture contained in the rice cake 5. It is possible to maintain the dry state of the sheet-like food 4 for a long time, the appearance after unpacking is good, and the texture is also excellent.

FIG. 2 is a perspective view in which a lump of rice (triangle rice ball) is placed on the packaging sheet according to the present invention. FIG. 3 is a cross-sectional view taken along line AA in FIG. FIG. 4 is a perspective view in the course of packaging a lump of rice with a packaging sheet according to the present invention. FIG. 5 is a perspective view of a packaged rice cake obtained by packaging a rice cake with the packaging sheet according to the present invention. FIG. 6 is a perspective view showing a procedure for unwrapping the packed rice lump. FIG. 7 is a perspective view showing a procedure for unpacking the package following FIG. FIG. 8 is a perspective view showing a procedure for unpacking the package following FIG. FIG. 9 is an explanatory view showing the inner film divided along the dividing guide zone.

  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 3 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 of 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 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 FIGS. As the inner film 3, it is desirable to employ a directional film so that the cutting is easy along the cutting guide band 31 described below. In this case, the easy dividing direction of the directional film is made to coincide with the direction of the outer dividing possible portion 21 of the outer film 2. The direction in which the directional film can be divided is made to coincide with the longitudinal direction of the cut tape 22 when the outer partable portion 21 is the cut tape 22.

  Further, the inner film 3 may be a directional film instead of the directional film, or may be configured such that the inner film 3 is thinned along the dividing guide band 31. For example, the thinning can be exemplified by a groove formed by a heated iron, a rotating round blade, a roller or the like. By pulling the inner film 3 to the left and right, the groove tears, and the inner film 3 can be divided along the groove.

  In addition, since the inner film 3 is in contact with the rice chunk 5, it is preferable to use a material having a high detachability with respect to the rice chunk 5.

  As shown in FIGS. 1 and 3, the inner film 3 is provided with a cutting guide band 31 at a position substantially opposite to the outer cuttable portion 21 of the outer film 2. The division | segmentation induction | guidance | derivation belt | band | zone 31 can be made into the strip | belt-shaped body of width about 1 mm-5 mm, for example, is formed from a film. The division guide band 31 can be attached to the inner film 3 by adhesion or heat welding. Desirably, the splitting induction band 31 is attached to the sheet-like food 4 side of the inner film 3 in order to prevent the lump 5 from adhering and becoming resistance when unwrapping. Desirably, the splitting induction band 31 employs a material that is harder to tear than the inner film 3 or a material that is more stretchable than the inner film 3 in order to prevent being split together with the inner film 3. An example of this type of material is a narrow film used for a cut tape.

  In the inner film 3, it is desirable to form an inner dividing start portion 33 at one end or both ends of the dividing guide band 31. The inner cutting start portion 33 can be exemplified by a cut as shown in FIGS. 1 and 2. When dividing the inner film 3, the inner dividing start portion 33 becomes a dividing start end and can easily divide the inner film 3 along the dividing guide band 31. In addition, when providing the inner part division start part 33 only in the end of the division | segmentation induction | guidance | derivation belt | band | zone 31, the inner side division | segmentation start part 33 can be provided in either side or both of the division | segmentation induction band 31. On the other hand, when the inner division start portions 33 are provided at both ends of the division guide band 31, the inner division start portions 33 and 33 are not provided on both sides of the division guide band 31, but as shown in FIG. 1 and FIG. Or on the same side. This is to prevent the inner film 3 from being divided along the dividing guide band 31 from the inner dividing start portion 33 located at the diagonal, and the splits intersecting on the dividing guide band 31.

  In addition, when forming the thin groove | channel along the division | segmentation induction | guidance | derivation belt | band | zone 31 in the inner film 3, it is suitable to form the inner side division | segmentation start part 33 so that it may overlap with the groove | channel.

  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 severable portion 21 and the slicing induction band 31.

  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 at least the surface facing the sheet-like food 4 has no intermittent cuts or overlapping film pieces such as perforations. Therefore, invasion of moisture or the like caused by the inner film 3 can be almost completely prevented, and the dry state of the stored sheet-like food 4 can be suitably maintained over a long period of time. In particular, as will be described later, when the rice cake 5 is packaged with the packaging sheet 1, steam contained in the rice cake 5 and moisture contained in the rice cake 5 do not pass through the inner film 3. It is possible to prevent the sheet-like food 4 from getting wet.

  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 pulled to the corner 15a on the side where the inner division start portion 33 is not formed with respect to the division guide band 31 when the cut by the outer divisionable portion 21 described later is “1”. A number “2” indicating the direction and order is added. 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. Since the packaged rice lump 6 comprises the inner film 3 as a single film, the two pieces of film do not overlap as in the past, so that intrusion of moisture and the like can be prevented, and the stored sheet-like food 4 The dry state 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 split along the split guide band 31 from the inner split start portion 33 (for example, the cut) as shown in FIG. It spreads without passing through the induction band 31, and is divided into two inner film pieces 3a and 3b. Then, the inner film piece 3a is removed together with the removed outer film piece 2a.

  Even when a thin film is used for the inner film 3 along the directional film or the dividing guide band 31, it is difficult to divide the inner film 3 straight depending on how the force is applied. However, according to the present invention, since the split guide band 31 is provided, when the split approaches the split guide band 31 side, the split extends along the split guide band 31 without exceeding the split guide band 31. To go. For this reason, the inner film 3 can be divided almost straight.

  In the present embodiment, the corner 15a provided on the inner film piece 3a side opposite to the inner dividing start portion 33 is first pulled across the dividing guide band 31. This is because, when the inner film 3 is divided, the inner film piece 3a that is pulled first is opposite to the inner dividing start portion 33 even if the tear extends in a direction away from the dividing guide band 31. This is because the inner film 3 has no problem because the inner film piece 3b remaining on the side of the rice lump 5 is small. When the opposite side is pulled first, the inner film piece 3b remaining in the above case protrudes larger than the outer film piece 2b, and when the rice cake 5 is grasped from above the exposed sheet-like food 4 in the subsequent process. , The protruding inner film piece 2b may be pressed from above the sheet-like food 4, and the packaging may not be unraveled.

  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.

  FIG. 9 is an explanatory diagram in which the divided inner film 3 is developed. As shown in the figure, it can be seen that the inner film 3 is divided into two inner film pieces 3 a and 3 b substantially along the dividing guide band 31.

  The rice lump 5 wrapped in the obtained sheet-like food 4 is composed of the inner film 3 made of a single film. Since the food 4 is prevented from getting wet and 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 also excellent.

  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 said embodiment, although the rice lump 5 packaged by the packaging sheet 1 was a triangular rice ball, a rod-shaped rice lump may be sufficient. In this case, the outer severable portion 21 and the severing guide band 31 are formed so as to be located on the peripheral surface of the bar-shaped rice lump. The formation position is preferably the center in the longitudinal direction of the rod-shaped rice lump, but may be a position close to any end face. In addition, what is necessary is just to form the ear piece which covers the end surface of a rod-shaped rice lump suitably in the packaging sheet 1, when packaging a rod-shaped rice lump. Moreover, it is needless to say that various foods such as Gohei rice cake and hampen can be packaged without being limited to the rice chunk 5.

  Moreover, in the said embodiment, although the division | segmentation induction | guidance | derivation belt | band | zone 31 is one, a predetermined space | interval (for example, 2-5 mm) exists, two are provided in parallel, and the inner side division | segmentation start part 33 (for example, cutting) is provided between them. Thus, the inner film 3 can be divided more linearly.
