Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to packaging materials such as hand-rolled sushi and packaged sushi.

[0002]

2. Description of the Related Art As conventional packaged rice balls and hand-rolled sushi, there are widely known ones in which seaweed and rice are shielded by an intervening sheet and the intervening sheet is removed immediately before eating.

The above-mentioned packaging rice ball is one in which the intervening sheet is pulled out along the surface of the rice, and a small amount of salad oil is mixed in the rice to impart lubricity to the surface of the rice so that the intervening sheet can be easily pulled out. is there. On the other hand, for hand-rolled sushi,
It was difficult to pull out the intervening sheet because the cone-shaped sushi rice had a narrow angle. In addition, since oil cannot be mixed with rice, the intervening sheet cannot be pulled out. For example, when sushi rice is wrapped with a packaging sheet in which seaweed is placed between the outer sheet and the intervening sheet, the packaging sheet can be used when eating. Opened, removed the intervening sheet, and wrapped the sushi rice again with seaweed.

However, in the above hand-rolled sushi, removing the intervening sheet is troublesome. That is, it is necessary to open the sushi rice wrapped with the packaging sheet once to remove the intervening sheet, and then re-roll it with seaweed, which is troublesome. Nor is it hygienic.

Therefore, the present inventor arranges the intervening sheet folded in two on the seaweed placed on the outer sheet, and pulls the portion of the intervening sheet that comes into contact with the seaweed, so that the intervening sheet is inverted and the sushi is inverted. Invented a sushi packaging material and a sushi packaging that can be peeled off from rice (Japanese Patent Laid-Open No. 30485/1992).
(See No. 5).

As shown in FIG. 11, the wrapping material 2 of the present inventor inserts seaweed into a bag 5 provided at one end of the outer wrapping material 4 so that the bag 5 partially overlaps the bag 5. It is covered with a folded intervening sheet 8. A knob 8a is formed on the intervening sheet 8 on the side in contact with the seaweed.

In order to wrap the sushi rice 7 with the packaging material 2,
The conical sushi rice 7 is placed on the intervening sheet 8, and the packaging material 2 is wrapped around the sushi rice 7 so that the corners 2a of the packaging material 2 overlap the side edges 2b in the opposite direction. Then, as shown in FIG. 12, the side edge 2c in the longitudinal direction of the packaging material 2 is attached to the outer packaging material 2 by the seal 6 to make the packaged sushi 9. Then, the knob 8a of the interposition sheet 8 is exposed.

[Problems to be Solved by the Invention]

However, in the packaging material 2 or the packaged sushi 9, when the intervening sheet 8 is pulled out, the grip portion 8a is pulled, but since the grip portion 8a is small, it is difficult to pull and the grip portion 8a is easy to tear. On the other hand, if the rectangular intervening sheet 8 is made of a material that is simply rolled up, there is no waste of material. However, the intervening sheet 8 having the knob 8a requires additional processing and waste of material. And

Therefore, an object of the present invention is to provide a packaging material such as sushi and a packaging sushi from which an intervening sheet as an inner packaging material can be easily removed.

[0010]

In order to solve the above problems, the present invention has the following constitution. That is, a sheet-shaped food material such as seaweed is placed on the outer packaging material made of a rectangular film, and the folded portion of the intervening sheet folded in two on the exposed portion of the food material is on the side edge in the width direction of the outer packaging material. Along with it, the interposing sheet is placed so as to cross the width direction of the outer wrapping material, while the portion of the intervening sheet that comes into contact with the food material is used as drawing means, and the width direction side edge portion of the outer wrapping material on the tip side of the drawing means is placed. It is characterized by having a notch.

A part of the exposed portion of the food material is covered with an intervening sheet, and the intervening sheet is close to one side in the longitudinal direction of the outer wrapping material, while the leading end portion of the pulling-out means is located in the width direction side of the outer wrapping material. The sushi rice is placed on the intervening sheet by projecting from the edge, and a notch is provided at a position where the intervening sheet does not exist at the side edge in the width direction of the outer packaging material on the tip side of the pulling-out means. , When the intervening sheet of the outer wrapping material is bent to one side and the corner portion on the leading end side of the pulling-out means is folded so as to overlap the side edge of the outer wrapping material where the folding portion of the intervening sheet is located, The projecting tip of the means overlaps the notch of the outer wrapping material.

On an outer wrapping material consisting of a rectangular film,
A portion where a sheet-shaped food material such as seaweed is placed, and the folded portion of the intervening sheet folded in two on the exposed portion of the food material is placed along the side edge in the longitudinal direction of the outer wrapping material so as to come into contact with the food material of the intervening sheet. Is used as the drawing means, and at least the drawing means has a length that covers the food material, while a notch is provided in the side edge portion of the outer packaging material where the drawing means overlaps.

The intervening sheet may be composed of only the pulling-out means. Alternatively, a conical sushi rice may be placed on the intervening sheet of each of the above-mentioned packaging materials, the sushi rice may be wrapped with the packaging material, and the end of the wrapped packaging material may be stopped on the outer packaging material to form packaged sushi.

[0014]

[Operation] The operation will be described. In order to prevent the sushi rice from contacting the sheet-shaped food such as seaweed, the food is wrapped around the sushi rice with an intervening sheet interposed between the food and the sushi rice. Remove the exposed part from and bring the food into contact with the rice.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings. FIG. 1 shows a disassembled state of the packaging material. 2 and 3 are explanatory views showing the manufacturing process of the packaging material.

The packaging material 12 for hand-rolled sushi is the outer packaging material 14
And seaweed 16 which is a sheet-shaped food material and an intervening sheet 18 as an inner packaging material.

2 and 3 show a procedure for forming the packaging material 12 by stacking the interposing sheet 18. As shown in FIG. 2, the seaweed 16 is placed on the outer packaging material 14 so as to cover one-third of the seaweed 16 at one side in the longitudinal direction of the drawing.
The interposition sheet 18 is placed so that both ends thereof protrude in the width direction of the outer packaging material 14. The intervening sheet 18 may not cover the right end of the Shanghai moss 16 shown in FIG.

One portion of the interposing sheet 18 that largely protrudes in the width direction of the outer wrapping material 14 has an inner portion 1 that contacts sushi rice.
8a. The other extending portion is a picking portion 18b. Then, the outer wrapping material 14 and the interposition sheet 18 are welded to each other at a boundary portion between the interposition sheet 18 and the inner portion 18a. This welded part is 2
Set to 2. The welded portion 22 is used as a folded portion to form the inner portion 1
8a is bent, and the leading edge portion of the inner portion 18a, the interposing sheet 18 and the outer wrapping material 14 are integrally welded. This welded portion is 24. The welded portion 24 is not always necessary.

A portion other than the inner portion 18a of the interposing sheet 18 is used as a pulling-out means. That is, a part of the interposition sheet 18 that overlaps the inner part 18a (referred to as an overlapping part 18c) and the picking part 18b constitute the pulling-out means 20. The knob portion 18b extends longer than the inner portion 18a. That is, the protruding length L of the knob 18b is a length that covers the exposed length M (about 1/3) of the seaweed 16.

A notch 15 is formed in a part of the side edge 14a of the outer packaging material 14 which is not covered by the pulling-out means 20 and which is on the protruding edge side of the knob 18b. When the sushi or the like is packaged, the notch 15 has a pull-out means 20.
To expose a part of.

Although the packaging material 12 is constructed as described above, the intervening sheet 18 may be fixed to the outer packaging material 14 by spot welding. The bent portion of the interposition sheet 18 is located along the side edge of the outer wrapping material 14 in the width direction, that is, the bent portion of the interposition sheet 18 is the side edge of the outer wrapping material 14 in the width direction opposite to the cutout 15. It is arranged along with.

A case of winding sushi rice 34 (shown by a dotted line) using the packaging material 12 configured as described above will be described. The cone-shaped sushi rice 34 is placed on the inner portion 18 a of each intervening sheet 18. In addition, conical sushi rice 3
4 are arranged diagonally so that the tops thereof face the direction of the welded portion 24 (see FIG. 3).

The sushi rice 34 is rolled from the corner 12a of the packaging material 12, and the seaweed 16 is covered by the picking portion 18b of the packaging material 12. Then, a part of the knob 18b overlaps the notch 15. In this state, the portion of the packaging material 12 that overlaps the knob 18b is wrapped so as to cover the vicinity of the corner 12a of the packaging material 12. Then, the end portion of the packaging material 12 is attached to the outward direction material 14 by a seal 26 or the like,
A hand-rolled sushi roll 36 is produced (see FIG. 4). A part of the pulling-out means 20 located in the notch 15 of the outer packaging material 14 is exposed.

Next, the procedure for removing the packaging material 12 of the hand-rolled sushi roll 36 configured as described above and bringing the seaweed 16 into close contact with the sushi rice 34 will be described. The knob 18b of the pull-out portion 20 exposed from the notch 15 of the outer packaging material 14 is pulled. Then, the intervening sheet 1
The overlapping portion 18c of 8 is pulled, and this force causes the welded portion 2
4 and the welded portion 22 are peeled off one after another.

Further, the grip portion 18 of the interposing sheet 18
When b is pulled, the inner portion 18a of the intervening sheet 18 is gradually pulled toward the back side and sequentially peeled off from the sushi rice 34. That is, instead of pulling the intervening sheet 18 along the sushi rice 34 to peel it off, the inner portion 18a of the intervening sheet 18 which is in contact with the sushi rice 34 is pulled by the overlapping portion 18c so as to be peeled to the back side and is sequentially inverted. Therefore, the interposition sheet 18 is smoothly peeled off from the sushi rice 34. And
When the intervening sheet 18 is pulled out, the seaweed 16 comes into close contact with the sushi rice 34.

Next, the seal 26 attached by a seal or the like on the outer surface of the outer packaging material 14 on the side of the picking portion 18b of the packaging material 12 is peeled off. Then, the outer packaging material 14 can be completely peeled off and eaten as it is. Alternatively, the sushi can be eaten by gradually peeling off the outer wrapping material 14 while being wrapped with the outer wrapping material 14.

In the above embodiment, the intervening sheet 1 is used.
The width of 8 may be the same as the length of the outer packaging material 14. In this case, the knob 18b may not be provided, and the overlapping portion 18b
c (pull-out means 20) covers the notch 15 of the outer packaging material 14, and when the sushi rice 34 is packaged, the notch 1
A part of the overlapping portion c (drawing means 20) is exposed from 5.

5 to 8 show another embodiment. In this embodiment, the outer wrapping material 14 and the seaweed 16 have the same form as the above embodiment, but the configuration of the intervening sheet as the inner wrapping material is different.
The intervening sheet of this embodiment is designated as 28.

That is, the wrapping material 12 for hand-rolled sushi is composed of an outer wrapping material 14, seaweed 16, and an intervening sheet 28.

6 to 8 show a procedure for forming the packaging material 12 by stacking the interposition sheet 28. As shown in FIG. 6, the seaweed 16 is placed on the outer packaging material 14, and the seaweed 16
The entire sheet of the
One end of 8 extends. The extending portion is an inner portion 28a that contacts the sushi rice. The portion of the intervening sheet 28 that covers the seaweed 16 is the pulling-out means 20. A portion of the pulling-out means 20 located in the notch 15 of the outer packaging material 14 will be referred to as a pick portion 28b. The intervening sheet 2
The overlapping portion with the inner portion 28a of 8 is the overlapping portion 28c, and the four corners of the overlapping portion 28c are welded to the outer packaging material 14 by spot welding. This welded portion is 19. The welded portion 19 is not always necessary.

Then, as shown in FIG. 7, the interposition sheet 2
Among them, the inner side portion 28a is folded so as to overlap the overlapping portion 28c, and the packaging material 12 is completed (see FIG. 8).

A case where sushi rice 34 (shown by a dotted line) is wrapped with the packaging material 12 configured as shown in FIGS. 5 to 8 will be described. The cone-shaped sushi rice 34 is placed on the inner portion 28a of the interposing sheet 28 (see FIG. 5). The conical sushi rice 34 is diagonally arranged so as to face the notch 15 (see FIG. 5).

Then, as shown in FIGS. 3 and 4, by rolling the sushi rice 34, the picking portion 28b is exposed at the position of the picking portion 18b in FIG.

The picking portion 18 of the pulling means 20 is
b, 28b are the overlapping portions 18c, 28c and the inner portion 18
It does not have to have the same width as a and 28a, and may be simply exposed from the notch 15. Further, the width of the inner portions 18a and 28a may not be the same as that of the inner portions 18a and 28a. The intervening sheets 18 and 28 are preferably made of a synthetic resin film having high flexibility and coated with silicon. On the other hand, a polypropylene film or the like is suitable as the outer packaging material.

In the embodiment shown in FIG. 7, the inner sheets 18a and 28 may not have the inner portions 18a and 28a (see FIGS. 9 and 10). In this case, sushi rice or the like is placed on the overlapping portions 18c and 28c of the intervening sheets 18 and 28, and wrapped and packaged in the same manner as above. Then, from the notch 15 of the outer packaging material 14, the interposition sheet 18,
Part of the knob portions 18b, 28b of 28 will be exposed. In this embodiment, the intervening sheets 18 and 28 are not peeled from the sushi rice, but pulled out along the surface of the sushi rice.

Further, in the embodiment shown in FIGS. 1 to 4, the width of the interposition sheet 18 may be the same as the length of the outer wrapping material 14 in the longitudinal direction. In this case, the knob 18b may be omitted, and a part of the overlapping portion 18c is located in the notch 15, and the knob 18b shown in FIG. 4 is located in the overlapping portion 18c. .

Although various explanations have been given with reference to the preferred embodiments of the present invention, the present invention is not limited to the above embodiments, for example, the shape of the notch is not limited, and the spirit of the invention is not limited. It goes without saying that many modifications can be made without departing from the scope.

[0038]

The packaging material for hand-rolled sushi and the like according to the present invention and the packaged sushi have a part of the picking portion (pulling-out means) of the intervening sheet exposed from the outer packaging material, so that the intervening sheet can be easily used as it is. It can be pulled out and stripped. Further, by simply winding sushi rice or the like, a part of the intervening sheet pulling-out means can be exposed, and automation of packaging or the like can be performed. Further, as in the conventional case, the pinching portion of the intervening sheet is easily torn, and the material is not wasted.
