Description

  The present invention relates to a packaging sheet containing a sheet-like food between an outer film and an inner film, and packaging sushi wrapped with the packaging sheet.

In this type of packaging sheet, as shown in FIGS. 9 and 12, the inner film (4) formed of two inner film halves (41) and (41) covers both end faces of the rolled sushi (6). For this reason, there are some which have the extended portions (41a) and (41a) protruding from the outer film (1).
In the packaging sheet (5) of FIG. 9, rectangular extensions (41a) (41a) extend over the entire length of the inner film halves (41) (41) in the longitudinal direction.
The packaging sheet (5) in FIG. 12 has an extension (41a) (41a) extending from the central part in the longitudinal direction of both inner film halves (41) (41) into a substantially square shape slightly larger than the end face of the rolled sushi (6). Is extended.

  The wrapping sheet (5) shown in FIG. 9 is rolled onto the inner film (4) at right angles to the belt-like overlapping portions (40) between the inner ends of the inner film halves (41) and (41). 6) is placed, and the extension portions (41a) and (41a) of the inner film halves (41) and (41) are raised to cover the end faces of the rolled sushi (6). Furthermore, as shown in FIG. 10, for each extension part (41a) (41a), three folding pins (8) are brought close to the outer peripheral edge of the end part of the sushi roll (6) to roll the sushi roll. The extension parts (41a) and (41a) are folded inward so as to be opposed to each other in the longitudinal direction of (6). In this state, the packaging sheet (5) is wrapped around the rolled sushi (6) and then folded. The pin (8) was pulled out and packaging was possible mechanically.

  In addition, the extended portions (41a) and (41a) of the inner film halves (41) and (41) extend over the entire length of the inner film halves (41) and (41), so that the folding pins (8) are pushed. When the folding part (41a) (41a) is folded so as to cover the outer periphery of the end of the rolled sushi (6), both ends (51) (52) of the packaging sheet (5) are extended parts (41a) (41a) There is an advantage that the packaging sheet is easily wound around the rolled sushi (6).

However, when the sushi roll (6) is placed on the inner film halves (41) (41), if it is tilted from the correct position, as shown in FIG. 11, from the winding end (52) of the packaging sheet (5), The extension portions (41a) and (41a) of the inner film halves (41) and (41) protrude and there is a problem that the commercial value is impaired.
In addition, both ends of the extension part (41a) of the inner film (4) do not contribute to the packaging of the end part of the rolled sushi (6), and the wrapping sheet (5) is wrapped around the rolled sushi (6). Increases the bulk of the packaging and impairs the aesthetics of the packaging.

  The extensions (41a) and (41a) of the inner film (4) of the packaging sheet (5) shown in FIG. 12 are the minimum size necessary for wrapping the end including the end face of the rolled sushi (6), Automatic packaging using a folding pin (8) as shown in FIG. 8 is difficult.

  In the present invention, the extension (41a) of the inner film halves (41) (41) protrudes from the winding end (52) of the packaging sheet (5) without impairing the advantages of the packaging sheet shown in FIG. It is intended to clarify a packaging sheet and packaging roll sushi that can prevent this and package sushi rolls with less bulk.

  The packaging sheet (5) of the present invention contains the sheet-like food (3) between the outer film (1) and the inner film (4), and the outer film (1) outside the sheet-like food (3). The inner film (4) and the inner film (4) are thermally welded to each other, and a severable portion (11) is provided along the longitudinal direction of the outer film (1) at a substantially central portion in the width direction of the outer film (1). ) Consists of two inner film halves (41) (41) that overlap the outer film (1), and both inner film halves (41) (41) are also on the end face of the rolled sushi (6) to be wrapped. In the packaging sheet (5) having the extension portions (41a) and (41a) protruding from the outer film (1) so as to cover the extension portions (41a) (over the entire length of the inner film halves (41) and (41)). 41a) extends, and cut portions (41b) and (41b) are provided at both outer ends of the respective extensions (41a) and (41a).

  The wrapping sushi roll according to the present invention is formed on the inner film (4) of the packaging sheet (5) according to any one of claims 1 to 4 and has a band shape with the inner ends of the inner film halves (41) (41). Place the rolled sushi (6) so that it is perpendicular to the overlap (40) and both ends do not protrude in the width direction of the outer film (1), and the extension (41a) of the inner film halves (41) (41) Fold (41a) inward and cover both ends of the rolled sushi (6) including both ends, wrap the packaging sheet (5) around the rolled sushi (6), and seal the wound end (52) (7) Joined by thermal welding or the like.

In the packaging sheet (5) of the present invention, the extension portions (41a) and (41a) of the inner film (4) extend over the entire length in the longitudinal direction of the inner film (4). When the extension part (41a) (41a) is pushed inward using the folding pin (8), both ends (51) (52) of the packaging sheet (5) are pulled by the extension part (41a) (41a). Float up. For this reason, since it becomes easy to grasp the edge part of a packaging sheet (5), it becomes easy to wind a packaging sheet (5) around a rolled sushi (6).
In addition, since cut portions (41b) and (41b) are provided at both outer ends of the extension portions (41a) and (41a), when rolling the sushi (6), the rolled sushi (6) is put into the inner film half (41). Even if it is placed on the (41) with a slight inclination from the correct position, it is possible to prevent the extended portions (41a) and (41a) from protruding from the winding end (52) of the packaging sheet (5) to impair the commercial value.

FIG. 1 is a packaging sheet (5) of the present invention, and FIG. 2 is a sectional view thereof.
As shown in FIG. 3, the packaging sheet (5) is formed by placing a strip-shaped intermediate film (2), a sheet-like food (3), and an inner film (4) on a rectangular outer film (1) in this order. The outer film (1), the inner film (4) and the intermediate film (2) are heat-welded at the outer periphery of 1).

The rolled sushi (6) packaged by the packaging sheet (5) has a substantially circular cross section, a length of about 10 cm, and a diameter of about 3.5 cm.
Of course, the rolled sushi (6) may have a substantially square cross section.

The outer film (1) has a vertical length of about 15.5 cm and a horizontal length (width length) of about 12.5 cm.
The outer film (1) is provided with a separable portion (11) along the longitudinal direction at the center in the width direction, and the separable portion (11) of the embodiment is an intermittent incision (11a).

  The intermediate film (2) is for covering the intermittent incision strip (11a) to prevent the outside air from entering from the incision strip (11a), and is formed in a strip shape, and the length is the outer film. It is the same as the vertical length of (1), and the width is about 1.5 cm.

The sheet-like food (3) is a rectangle having a length of about 14 cm, a width of about 10 cm, and a size smaller than the outer film (1). The sheet-like food (3) is accommodated between the outer film (1) and the inner film (4) so that the center substantially overlaps the center of the outer film (1).
The sheet-like food (3) of the example is a sheet-like seaweed.

The inner film (4) is composed of two inner film halves (41) and (41) having the same shape, and the inner film halves (41) and (41) also cover the end face of the rolled sushi (6). Further, in the packaging sheet (5) having the extension portions (41a) and (41a) protruding from the outer film (1), the extension portions (41a) and (41a) are extended over the entire length of the inner film halves (41) and (41). The cut portions (41b) and (41b) are provided at both outer ends of the respective extension portions (41a) and (41a).
The cut portion corresponds to a shape in which both ends of the rectangular extension portions (41a) and (41a) in FIG.
The inner ends of the inner film halves (41) and (41) overlap each other with a width of about 1 cm.
The outer edge length L parallel to the outer film (1) of the extension part (41a) of both inner film halves (41) and (41) is about 11.5 cm, and the protruding height H from the outer film (1) ( As long as the extension portion (41a) can cover the end portion including the end face of the rolled sushi (6) with a margin, the size is not limited.

  Both ends of the outer film (1), the inner film half (41) (41) and the intermediate film (2) surround the sheet-like food (3) with a little inner plate from the outer periphery of the outer film (1). Then, heat welding (12) (13) is performed. However, the inner film halves (41) (41) are not thermally welded to the overlapping portion (40).

The outer film (1), the inner film (4), and the intermediate film (2) are formed of rice, that is, a film having poor adhesion to the rolled sushi (6), for example, polypropylene.
The film pieces (41) and (41) of the inner film (4) that are in direct contact with the rolled sushi (6) have a roughened surface and are translucent. By roughening the film pieces (41) and (41), the poor adhesion to the sushi roll (6) is further enhanced.

Next, the procedure for packaging the rolled sushi (6) using the packaging sheet (5) will be described.
As shown by the two-dot chain line in FIGS. 1 and 2, roll sushi (6) on the inner films (4) and (4) of the packaging sheet (5) and the inner halves (41) and (41) of each other. Place it so as to be perpendicular to the overlapping part (40) between the inner ends. At this time, both ends of the rolled sushi (6) should not protrude from both ends in the width direction of the sheet-like food (3).

The extension parts (41a) and (41a) of the film pieces (41) and (41) are erected so as to cover both end faces of the rolled sushi (6). Next, three folding pins (8) are brought close to the outer peripheral edge of the end face of the rolled sushi (6) with respect to the respective extensions (41a) and (41a), and the longitudinal direction of the rolled sushi (6) is reached. The extension parts (41a) and (41a) are folded inward so as to face each other, and in this state, the packaging sheet (5) is wound around the rolled sushi (6), and the winding end is sealed by the sealing piece (7) Join.
If the end of the seal piece (7) is left floating without adhering to the film, it can be easily picked with a fingertip and peeled off.
Of course, instead of the seal piece, the winding end of the packaging sheet can be fixed by thermal welding.

To unwrap the wrapping sushi roll, one side of the wrapping sushi roll is supported with one hand, and the seal piece (7) is peeled off with the other hand. With the hand that peeled off the seal piece (7), the other end side film of the wrapped sushi roll is picked and pulled. The outer film (1) is divided by the slits (11a), and the inner film (4) is separated into two inner film halves (41) (41) from the beginning. Half of the packaging sheet (5) to be removed is pulled out.
The extension parts (41a) and (41a) that are in direct contact with the rolled sushi (6) are roughened and have poor adhesion to the rolled sushi (6), so when pulling out half of the packaging sheet (5), The frictional resistance with the sushi roll (6) is small, and it is possible to prevent the sushi roll (6) from being broken due to excessive force applied to the sushi roll (6).
When the outer end of the remaining packaging sheet (5) is picked and pulled outward, the other half of the packaging sheet (5) can be smoothly pulled out in the same manner as described above, leaving the sheet-like food (3). The sheet-like food (3) is directly put on the rolled sushi (6).

  7 and 8 show another embodiment of the severable portion (11) of the outer film (1), and FIG. 7 shows a directional film in which the outer film (1) is easily split in the longitudinal direction. Two short cuts (11b) (11b) are provided in parallel at the center of the end. By picking and pulling between the parallel cuts (11b) and (11b), the outer film (1) can be easily divided into two minutes.

  8 is a so-called cut tape (11c) obtained by adhering a strip tape with a strong adhesive. When one end of the tape is pulled to the opposite side, the outer film (1) can be divided into two. . In the case where the severable portion (11) shown in FIGS. 6 and 7 is carried out, the intermediate film (2) can be omitted because there is no intrusion of outside air as in the case of the intermittent incision strip (12) shown in FIG.

The present invention is not limited to the configuration of the above embodiment, and various modifications can be made within the scope of the claims.
For example, the winding end of the wrapping sheet (5) wound around the rolled sushi (6) can be heat-welded so as to be peeled off, so that the package is not peeled off.
