Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a conical sushi packaging sheet in which a sheet-shaped food product such as seaweed is sandwiched between an outer film and an inner film, and a packaged conical sushi packaged with the packaging sheet. Is.

[0002]

2. Description of the Related Art A wrapping sheet in which sheet-like seaweed is sandwiched between an outer film and an inner film is used to wrap triangular rice ball rice to prevent moisture from the seaweed, and the outer film and inner film are used when eating rice balls. A packaging sheet and a packaging rice ball that can be removed and directly covered with dried sheet-like seaweed on rice ball are widely known.

Recently, mass production of hand-rolled sushi by mechanical force has been carried out, similar to the hand-rolled sushi in which rice is rolled into a conical shape with sheet-shaped seaweed. As shown in FIG. 7, the packaging sheet for hand-rolled sushi has a rectangular outer film in the same manner as the conventional packaging sheet for triangular rice ball rice.
The sheet-shaped laver (31) is sandwiched between the (1) and the inner film (2), and the outer peripheries of the outer film (1) and the inner film (2) are heat-welded to each other. The inner film (2) is a large film piece (2
The inner ends of the small film piece (3) and the small film piece (24) are overlapped with each other, and the strip-shaped overlapping portion (20) is orthogonal to the longitudinal direction of the inner film (2). The rice (5) collected in a substantially conical shape is placed with its tapered tip positioned near the outer edge of the inner film (2) in the longitudinal direction, and the packaging sheet is placed on the inner film (2).
It is wrapped around the conical surface of.

To eat sushi, unpack it and cook
(5) is placed on the large film piece (23) and the small film piece (2
Remove 4) from the outer film (1) to expose the sheet-like seaweed (31). (FIG. 8A). Roll the rice (5) and place it on the exposed sheet-like seaweed (31) (Fig. 8B). The outer film (1) and the large film piece (23) are pulled to expose the entire sheet seaweed (31), and the conical surface of the rice is wrapped with the sheet-like seaweed (31) (Fig. 8).
C).

The above procedure is easy if the wrapped sushi is placed on a table, but it is difficult to carry it while holding it in hand. In addition, if the wrapped sushi is placed sideways on the table and the above-mentioned work is performed, the ingredients (6) are spilled and the beauty of the hand-rolled sushi is impaired, and the spilled ingredients stain the table. Moreover, rice (5) and seaweed (3
When winding 1), there is a problem that the rice (5) directly touches and sticks. Further, in the above packaging sheet, only the conical surface of sushi is packaged, and the enlarged front end surface is exposed, which is unsanitary.

As shown in FIGS. 9 and 10, the outer film (1)
Is also provided with a protruding portion (10) protruding in an L-shape from the inner film (2), and a packaging sheet for covering the enlarged tip of the conical sushi with the protruding portion (10) is also proposed (Actual Kaihei 3). -5
8989). However, the wrapping sheets shown in FIGS. 9 and 10 have the outer film (1) corresponding to the right side edge of the inner film (2) and the approximately right half of the longitudinal direction continuously from the edge. Since it protrudes into an L shape, it is difficult to automatically weld and cut the long strip-shaped film while unwinding and producing the same as in the case of producing a conventional packaging sheet.

In the inner film (2) of the packaging sheet shown in FIGS. 9 and 10, the large film piece (23) and the small film piece (24) are overlapped at their inner ends, and the strip-shaped overlapping portion (20) is formed. ) Is orthogonal to the longitudinal direction of the inner film (2). A cut tape (41) is applied to the outer film (1), but the direction of the cut tape is orthogonal to the longitudinal direction of the film.

As shown in FIG. 11, rice and utensils are placed on the right half of the inner film (2), and as shown in FIG.
Fold the right side of (4) into a triangle to wrap rice. The left half of the packaging sheet is placed on the previously bent portion, and the bent end is attached with the label (7) as shown in FIG.

When eating packaged sushi, the outer film (1) is divided into two large and small film pieces (13) (1) by the cut tape (41).
The label (7) is cut into 4 pieces, but the small film piece (13) cannot be pulled out to the tapered side of the sushi, and must be pulled out to the side along the conical surface of the sushi. In addition, the large film piece (14) covers the entire conical surface from the tapered tip of the conical sushi, and even if the large film piece (23) is pulled, the pulling resistance is too large to come off. If you remove it forcibly, the sushi will break. The packaging sheet of FIGS. 9 to 13 and the sushi packaged with the sheet have not been realized.

The present invention clarifies a conical sushi packaging sheet and a conical sushi packaging that can solve the above problems.

[0011]

The packaging sheet of the present invention comprises a sheet-shaped food product between a rectangular outer film (1) and a rectangular inner film (2) consisting of two film pieces (21) (22). A conical sushi packaging sheet formed by heat-sealing the outer edges of an outer film (1) and an inner film (2) with (3) sandwiched between the inner film (2) and two film pieces of the same length. (21) (22) is formed in a rectangular shape by overlapping the inner edges in the longitudinal direction, and the outer film (1) protrudes from one side edge along the longitudinal direction of the inner film over the entire length of the side edge. It has a protruding portion (10), and the outer film (1) is provided with a separable portion (4) corresponding to a position overlapping with the inner film (2) along the entire length of the inner film in the longitudinal direction. The strip-shaped overlapping portions (20) of the film pieces (21) and (22) of the inner film (2) are substantially parallel to the separable portion (4) of the outer film (1).

In the packaged conical sushi product of the present invention, rice is placed on the inner film (2) of the above-mentioned packaging sheet, and the rice is wrapped in the packaging film so that the protruding portion (10) side of the outer film (1) expands. The sheet is wound in a conical shape, the outer end of the sheet is joined by a label (7), heat welding, etc., and the protruding end side of the substantially conical sushi is covered by the protruding portion (10) of the outer film (1).

[0013]

FUNCTION AND EFFECT The conical sushi product is hygienic because it covers the area from the tapered base end to the enlarged distal end surface with a film, and can prevent rice from drying and maintain freshness. To unwrap, wrap sushi with taper side down and outside film
(1) is bisected from the separable part (4) in the width direction of the outer film (1). The inner film (2) is formed by stacking a large film piece (21) and a small film piece (22) at the inner edge thereof, and is divided into two in the width direction from the beginning. Therefore, pulling the tapered end of the sheet-wrapped conical sushi downwards, the outer film (1)
The lower film piece (22) and the lower film piece (22) of the inner film (2) can be pulled out together, and the lower part of the sheet-shaped food product (3) is exposed to the outside and directly covers the tapered portion of the conical sushi.

Next, the exposed portion of the sheet-shaped food product (3) is grasped by one hand, and the upper end of the sheet is grasped by the other hand and pulled upward. The upper half of the outer film (1) and the large film piece (23) are pulled out together, and the sheet-shaped food product (3) covers the entire conical surface of the rice.

As described above, the wrapping sushi is divided into two parts in the width direction of the outer film (1) from the separable portion (4) with the tapered tip facing downward, and the wrapping sheet is placed on the lower side. By pulling the film upwards, you can pull out only the film and cover the sheet-shaped food (3) directly on the rice. There is no trouble of unwrapping the food on the table, and the ingredients at the top of the wrapped sushi spill. Instead, you can maintain the beauty of hand-rolled sushi. Furthermore,
The hands do not touch the rice directly, and there is no risk of the hands becoming sticky.

Example: The inner film (2) has a length of 220 mm and a width of 100
A large film piece (21) having a length of mm and a small film piece (22) having a length of 220 mm and a width of 55 mm are overlapped with one side edge in the longitudinal direction with a width of 15 mm. (2
Although 0) is not overlapped because it is simply overlapped, it may be weakly heat-spotted in spots so that it can be easily peeled off. The large film piece (21) and the small film piece (22) are formed of a film that easily slips on cooked rice and has excellent moisture resistance.

The outer film (1) has a length of about 220 mm and a width of about 2
It is 00 mm. The outer film (1) is formed of a stretched synthetic resin film that is easily torn in the longitudinal direction and is not torn in the lateral direction.

The outer film (1) is formed with a separable portion (4) for tearing the film in the longitudinal direction. The separable part (4) of the embodiment utilizes the property that the outer film (1) easily tears in the longitudinal direction.
The cuts (42) (42) are made at two places in the center of one edge of the. When the outer film (1) and the inner film (2) are overlapped with their one side edges in the longitudinal direction aligned with each other, the notches (42), (42) are located substantially at the center of the inner film (2) in the width direction. Is provided. When the gaps between the cuts (42) (42) are pinched and pulled, the outer film (1) is easily torn in the longitudinal direction by the width between the cuts (42) (42) and divided into two in the width direction.

The sheet-shaped food product (3) is a rectangular sheet-shaped laver (31) which is slightly smaller than the inner film (2) in the embodiment. A sheet-shaped laver (31) is sandwiched between the outer film (1) and the inner film (2), and the outer peripheral edges of both the inner and outer outer films (1) and (2) are separated into large and small film pieces (21) of the inner film (2). ) (22) except the overlapping part (20) and the separable part (4) are heat-welded to form a packaging sheet.

In order to wrap conical sushi with the above-mentioned packaging sheet, rice is first placed on the inner film (2) of the packaging sheet. It is easy to wrap the rice if the rice is put together in a substantially conical shape and the taper base end is placed in the vicinity of the outer edge of the small film piece (22) in the longitudinal direction. Wrapping sheet for outer film (1)
The rice is wound around the rice in a conical shape so that the protruding portion (10) is enlarged, and the outer ends of the sheets are joined by the label (7) and heat welding. The sushi ingredients (6) may be put together with the rice (5) or rolled in a conical shape and then placed on the rice (5).

The protruding portion (10) of the outer film (1) is squeezed and bound with an adhesive tape, a metal retaining ring or the like. This also covers the film on the tip side of the cone-shaped sushi on the enlarged side,
The conical sushi is wrapped in a film from the taper at the base end to the tip of the enlarged portion at the tip and sealed.

The conical wrapping sushi, however, is hygienic because the sheet covers from the tapered base end to the enlarged front end surface and is sanitary, and the rice can be prevented from drying and freshness can be maintained. To unwrap, wrap sushi with taper side down and outside film
(1) is bisected from the separable part (4) in the width direction of the outer film (1). The inner film (2) is formed by overlapping the wide film piece (21) and the narrow film piece (22) at the inner edge thereof, and is divided into two in the width direction from the beginning. Therefore, when the tapered end of the wrapping cone-shaped sushi of the sheet is pulled downward, the lower half of the outer film (1) and the lower film piece (22) of the inner film (2)
Can be pulled out together, and the lower part of the sheet-shaped seaweed (31) is exposed to the outside and directly covers the tapered part of the conical sushi.

Next, the exposed portion of the sheet-shaped food product (3) is grasped by one hand, and the upper end of the sheet is grasped by the other hand and pulled upward. The upper half of the outer film (1) and the large film piece (23) are pulled out together, and the sheet-shaped food product (3) covers the entire conical surface of the rice.

As described above, the wrapping sushi is divided into two parts in the width direction of the outer film (1) from the separable portion (4) with the tapered tip facing downward, and the wrapping sheet is placed on the lower side. You can pull out the film only and pull the sheet-like seaweed (31) directly on the rice by pulling it upwards, there is no trouble of unwrapping the wrapping on the table, and the ingredients at the top of the wrapped sushi will spill. Instead, you can maintain the beauty of hand-rolled sushi. Furthermore,
The hands do not touch the rice directly, and there is no risk of the hands becoming sticky.

FIGS. 5 and 6 show another embodiment of the separable portion (4). The separable portion (4) of FIG. 5 is an outer film.
The cut tape (41) is formed by adhering over the entire length of (1), and by pulling one end of the cut tape (41), the outer film (1) is torn by the width of the tape to form the outer film.
(1) can be divided into two parts on both sides of the tape (41). FIG. 6 shows that the outer film (1) is provided with perforations (43) (43) parallel to each other in the longitudinal direction of the film at a central portion in the width direction to form a separable part (4). It is a thing.

In the embodiment, since the protruding portion (10) of the outer film (1) is squeezed at the end of the packaging procedure, the portion of the packaging sheet which covers the enlarged side of the conical sushi when the packaging is unwound. Since there is little freedom and the pullout resistance is large,
Swap the positions of the large and small film pieces (21) and (22) of the inner film (2) so that the small film piece (22) is on the protruding portion (10) side of the outer film (1) and the large film piece (21) is on the opposite side. And the pull-out resistance of the inner film pulled out together with the protruding portion (10) can be reduced.

If the position of the separable portion (4) of the outer film (1) is closer to the protruding portion (10) side than the center portion of the inner film (2) in the width direction, the pull-out resistance of the outer film is increased. Can be made smaller. Even if the area of the film covering the tapered base end side of the conical sushi increases, the pull-out resistance does not become so large because of the draft.

The sheet-shaped food product (3) is not limited to the sheet-shaped seaweed (31), and may be any edible sheet-shaped product such as a sheet-shaped kelp.
