Description

  The present invention relates to a packaging sheet containing a sheet-shaped food between an outer film and an inner film, and a rod-shaped packaged food obtained by packaging a rod-shaped food with this packaging sheet. More specifically, the dried state of the sheet-shaped food The present invention relates to a packaging sheet and a bar-shaped packaged food that can maintain the above.

A rod-shaped packaged food obtained by packaging a rod-shaped rice cake with a packaging sheet is known.
The applicant has proposed a packaging sheet in which a sheet-shaped food such as laver is sandwiched between an outer film and an inner film, and a rod-shaped packaged food in which a rod-shaped rice lump is packaged with this packaging sheet (e.g., patent document). 1).

  A cut tape is formed on the outer film in the longitudinal direction, and the inner film is composed of an inner film piece that is approximately half the width of the outer film so that the inner side edges overlap each other at a position facing the cut tape. Moreover, the covering film which wraps the end surface of a rod-shaped rice lump is attached to the side edge of the inner film.

  And when unwrapping the bar-shaped packaged food packaged with the bar-shaped rice cake with this packaging sheet, cut the outer film with a cut tape, grab one edge of the divided packaging sheet and pull it to remove the sheet-shaped food One of the packaging sheets is removed, the stick-shaped rice cake is grasped from above the exposed sheet-like food, and the remaining packaging sheet is removed to obtain a stick-shaped rice cake wrapped with the sheet-like food.

Japanese Patent No. 5634235

  The packaging sheet covers the sheet-like food with the outer film and the two inner film pieces. Since the two inner film pieces only overlap the inner side edges, the moisture of the rod-shaped food enters the inside of the packaging sheet from the overlapped portion when the rod-shaped food is packaged. May end up. Moisturized sheet-like foods have a poor texture and may become sticky when the packaging sheet is removed and cannot be unpacked well.

  An object of the present invention is to provide a packaging sheet capable of maintaining the dry state of a sheet-like food, and a rod-like packaged food obtained by packaging a stick-like food with the packaging sheet.

In order to solve the above problems, the packaging sheet of the present invention is:
An outer film 20 comprising a breakable portion 21 formed in the longitudinal direction;
An inner film 30 consisting of two inner film pieces 31, 31 constituting an overlapping portion 33 where the inner side edges overlap at a position facing the severable portion 21;
Covered films 40, 40 mounted on the inner film 30, and the sheet-like food 50 sandwiched between the outer film 20 and the inner film 30,
A packaging sheet 10 for packaging a rod-shaped food 60, comprising:
The side edges on the inner side of the covering films 40, 40 have a length that overlaps with each other at a position facing the severable portion 21 to form the first overlapping portion 46 when the rod-shaped food 60 is packaged.

  The width of the covering films 40 and 40 is 1/2 or more of the outer peripheral length of the rod-shaped food 60 to be packaged.

  When the covering films 40 and 40 are covered with the end face of the rod-shaped food 60 to be wrapped and folded inward, the outer side edges overlap with each other at the position facing the severable portion 21, and the second film is overlapped. It has a length constituting the overlapping portion 47.

The rod-shaped packaged food of the present invention is
A rod-shaped food is packaged by the packaging sheet described above.

In addition, the rod-shaped packaged food of the present invention is
The covering films 40, 40 constitute the second overlapping portion 47 in which the outer side edges overlap with each other at a position facing the separable portion 21.

  The packaging sheet 10 is arranged so that not only the inner film pieces 31, 31 constituting the inner film 30 have the overlapping portion 33, but the covered films 40, 40 also have the first overlapping portion 46 with the inner side edges overlapping. ing. That is, between the sheet-like food 50 and the stick-like food 60, a total of four films overlap at the film overlap portion. Therefore, when the stick-like food 60 is packaged, moisture enters from the film overlap portion. Can be prevented as much as possible, and the dry state of the sheet-like food 50 can be maintained. Therefore, it is possible to prevent the sheet-like food 50 from becoming unpleasant in texture due to moisture or from being difficult to unpack.

  In addition, by setting the width of the covered films 40 and 40 to be 1/2 or more of the outer peripheral length of the rod-shaped food 60 to be packaged, the covered films 40 and 40 have an overlap portion of the film over the half circumference of the rod-shaped food 60. As a result, moisture can be prevented from entering as much as possible.

  Furthermore, the covering films 40, 40 are formed so as to have the second overlapping portion 47 where the outer edges overlap each other at a position facing the separable portion 21 when the stick-shaped food 60 is packaged. A total of four films are overlapped by these overlaps at a position opposite to each other, and moisture can be prevented from entering from the overlapping portions of the films as much as possible.

  In addition, in the above, by setting the width of the covered films 40 and 40 to be 1/2 or more of the outer peripheral length of the rod-shaped food 60 to be packaged, the overlapping portions of the covered films 40 and 40 are all of the rod-shaped food 60. Because it will be provided around. Moisture penetration can be made extremely difficult.

  The rod-shaped packaged food 70 formed by packaging the rod-shaped food 60 with the packaging sheet having the above-described configuration can prevent the moisture of the rod-shaped food 60 from moving to the sheet-shaped food 50 through the overlapping portion formed of four films as much as possible. Therefore, the dry state of the sheet-like food 50 can be maintained, and it is possible to prevent the sheet-like food 50 from being deteriorated in texture due to moisture or being difficult to unpack.

FIG. 6 is a perspective view showing a process of unwrapping the bar-shaped packaged food. FIG. 7 is a perspective view showing a process of unpacking the bar-shaped packaged food following FIG.

  Hereinafter, the stick-shaped packaged food of the present invention will be described with reference to the drawings.

  As shown in FIGS. 1 to 3, the packaging sheet 10 can be composed of an outer film 20, a sheet-like food 50, an inner film 30, and a covering film 40.

  The outer film 20 can be composed of a rectangular transparent film such as a rectangle. The shape of the outer film 20 is not limited to a rectangle, but may be a shape with a rectangular corner dropped. Further, the size of the outer film 20 is also appropriately determined.

  The outer film 20 is formed with a separable portion 21 in the longitudinal direction. The splittable portion 21 is formed at a substantially central position in the width direction of the outer film 20.

  As the part 21 which can be divided, the structure which sticks a cut tape on the inner surface side (sheet-like food 50 side) of the outer film 20 can be illustrated. In this case, it is desirable that the outer film 20 has a pair of cutting start portions 23 and 23 formed at the end edges with one end of the cut tape interposed therebetween. The cutting start portions 23 and 23 are short cuts in the illustrated embodiment, and are formed on the winding end 11 side.

  Although not shown in the figure as the separable portion 21, a configuration in which intermittent perforated cuts are made 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 band film on the inner surface of the outer film 20 along the cut.

  The inner film 30 is formed inside the outer film 20. The inner film 30 can be composed of a pair of inner film pieces 31, 31. The inner film pieces 31, 31 have a width that is ½ or more of the width of the outer film piece 30, and the inner edge is It has the overlap part 33 which overlapped in the position facing the part 21 which can be divided of the outer film 20. In addition, although the overlap part 33 of the inner film pieces 31 and 31 should just overlap, you may perform thermal welding (welding) spotly so that it can peel easily.

  The covered films 40 and 40 are films that cover the end face of the rod-shaped food 60 in the packaged state. In the present invention, the covered films 40, 40 not only cover the end surface of the rod-shaped food 60, but also form a film that prevents moisture from entering the sheet-shaped food 50 in the packaging sheet 10 together with the inner film 30. The covering films 40 and 40 are thermally welded to the outer surfaces (the bar-shaped food 60 side) of the inner film pieces 31 and 31, respectively.

  Specifically, as shown in FIG. 3, the covering films 40, 40 have long inner edge sides 41 extending, and have a first overlapping portion 46 that overlaps at a position facing the separable portion 21 of the outer film 20. Forming. Thereby, the overlapping part can be formed by four films together with the overlapping part 33 of the two inner film pieces 31, 31.

  Further, as shown in FIG. 3, the outer edge side 43 of the covered films 40, 40 also extends long from 42 covering the end surface of the rod-shaped food 60, and the covered films 40, 40 are covered on the end surface of the rod-shaped food 60. When folded inward, as shown in FIG. 5, it is desirable to form a second overlapping portion 47 that overlaps the outer edges at positions facing the separable portion 21 of the outer film 20. Thereby, the overlapping part can be formed by four films together with the overlapping part 33 of the two inner film pieces 31, 31.

  It is desirable that the width of the covering films 40, 40 be at least 1/2 of the outer peripheral length of the rod-shaped food 60 to be packaged. Thereby, more than half of the outer circumference of the rod-shaped food 60 faces the inner edge of the covering films 40, 40, and the first overlapping portion 46 can be made more than half of the rod-shaped food 60.

  Furthermore, when the outer edge of the covering films 40, 40 is also formed long, the entire periphery of the outer periphery of the rod-shaped food 60 can be covered with the covering films 40, 40, and the first overlapping portion 46 and the second overlapping portion. Since 47 is formed on the entire outer periphery of the rod-shaped food 60, the overlapping portion is formed by four films along with the overlapping portion 33 of the inner film pieces 31, 31 over the entire outer periphery of the rod-shaped food 60. Can do.

  The inner film 30 and the covering film 40 described above can improve the sliding with respect to the rod-shaped food 60 or the sheet-shaped food 50 by adopting an embossed film that forms unevenness by applying heat or pressure to the film, Easy to unwrap the packaging.

  The sheet-like food 50 sandwiched between the opposing inner surfaces of the outer film 20 and the inner film 30 can be exemplified by sheet-like seaweed. The sheet-like food 50 is not limited to the sheet-like seaweed, but is a thin food that does not hinder the covering of the packaging sheet 10 on the stick-like food 60, such as those obtained by forming a rag kombu into a sheet shape, or a thinly stretched rice cake. If it is.

  The packaging sheet 10 first covers the inner film pieces 31, 31 that are the inner film 30 by heat-welding the films 40, 40, respectively, and the sheet-like food 50 is interposed between the outer film 20 and the inner film 30. Repeat as shown.

  And the packaging sheet 10 can be produced by carrying out the heat welding of the outer film 20 and the inner film pieces 31 and 31, respectively.

  The rod-shaped food 60 packaged by the packaging sheet 10 can be exemplified by a rice lump solidified in a rod shape, and can be a rod-shaped rice lump such as white rice, vinegared rice, or rice. In addition, ingredients such as natto can be appropriately added to the rice lump. Of course, the rod-shaped food 60 is not limited to a lump of rice, and may be a bowl or the like. The shape of the rod-shaped food 60 can be a cylindrical shape, a triangular prism shape, a quadrangular prism shape, an elliptical column shape, or the like. In the illustrated embodiment, the rod-shaped food 60 has a columnar shape and the length is substantially the same as the width of the sheet-shaped food 50.

  In order to wrap the rod-shaped food 60 using the packaging sheet 10 of the present invention, as shown in FIG. 2, the inner film 30 side is directed upward, and the rod-shaped food 60 is placed so that the end surfaces are covered with the films 40 and 40.

  Next, the covering films 40 and 40 are put on the end face of the rod-shaped food 60 and folded back inside. At this time, when the outer edges of the covered films 40 and 40 are formed long, these edges are overlapped to form the second overlapping portion 47.

  Then, as shown in FIG. 4, the packaging sheet 10 is tightly wound around the peripheral surface of the stick-shaped food 60, and the winding end end 11 of the packaging sheet 10 is secured by a fastening means (not shown) such as a seal, tape, or heat welding. By sticking to the outer film 20, a rod-shaped packaged food 70 in which the rod-shaped food 60 is packaged by the packaging sheet 10 can be obtained.

  FIG. 5 is a cross-sectional view taken along line BB in FIG. As shown in the figure, the rod-shaped food 60 is formed of four films at the overlapping portion of the film by the overlapping portion 33 of the inner film pieces 31 and 31 and the overlapping portions 46 and 47 of the covering films 40 and 40. You can see that it is covered.

  Therefore, since it becomes difficult for the moisture from the stick-shaped food 60 to enter the inside of the packaging sheet 10 due to the overlapping portion formed by the four films, the sheet-shaped food 50 can be maintained in a dry state. .

  The obtained rod-shaped packaged food 70 can be unpacked in the following manner.

  First, the fastening means is peeled off, and the outer film 20 is divided as shown in FIG. In the present embodiment, since the separable portion 21 is a cut tape, the edge of the cut tape is picked and the cut tape is pulled and removed. By forming the cutting start portions 23 and 23 in the outer film 20, the cut tape can be pulled out easily.

  Subsequently, the bar-shaped food 60 is grasped from the one outer film 20 that has been divided, and the other outer film 20 is pulled in the width direction as shown in FIG. Thereby, half of the sheet-like food 50 is pulled out together with the inner film piece 31 and the covering film 40 and exposed in a state where it remains on the stick-like food 60. Then, the remaining outer film 20 is grasped and pulled in the width direction, whereby the remaining inner film piece 31 and the covering film 40 are removed together with the outer film 20, and the stick-shaped food 60 in which the sheet-like food 50 is wound around the outer periphery is obtained. be able to. Since the sheet-like food 50 is dried, the appearance and texture are good, and the problem that the packaging does not unravel due to stickiness when unpacking can be solved.

  The above description is for explaining the present invention, and should not be construed as limiting the invention described in the claims or limiting the scope thereof. Further, the configuration of each part of the present invention is not limited to the above-described embodiment, and various modifications can be made within the technical scope described in the claims.
