Description

  The present invention relates to a packaging material for cooked rice processed food, more specifically, a packaging material for packaging cooked rice processed food such as hand-rolled sushi and rice balls, comprising an inner packaging material and an outer packaging material, and the inner packaging material and the outer packaging material. The present invention also relates to a packaging material for cooked rice food, which is packaged in a state in which nori is placed between the inner packaging material and cylindrical rice for hand-rolled sushi or rice for rice balls is in contact with the inner packaging material.

  Conventionally, various types of packaging materials for processed rice foods, in which nori is interposed between the inner packaging material and the outer packaging material and the rice is in contact with the inner packaging material, have been developed. Packaged processed rice foods such as rice balls are sold at convenience stores.

  From the viewpoint of preventing dampness of the laver, the cooked rice processed food packaged with such a packaging material is blocked by the inner packaging material to prevent direct contact between the laver and the cooked rice. When doing so, it is necessary to release the blocking state by the enveloping material and to combine the laver and the cooked rice.

  When the outer packaging material and the inner packaging material are bag-shaped, the lower portion of the outer packaging material is opened, and the inner packaging material is pulled out from the opening to combine the laver and the cooked rice. However, such a packaging material in which the outer packaging material and the inner packaging material are bag-like cannot completely prevent foreign matter from entering from the lower opening, and when the inner packaging material is pulled out, In some cases, the contact becomes a resistance and cannot be pulled out smoothly.

Therefore, in order to solve such problems, as in the following Patent Document 1 and Patent Document 2, the outer packaging material and the inner packaging material are formed into a sheet shape, and the peripheral edge portion is sealed to prevent entry of foreign matter. Are also used. Since such a wrapping material is sealed at the periphery, means for opening the wrapping material is required, and as the opening means, opening means such as a cut tape is generally employed. However, with such a means of opening with a thin cut tape, the opening is performed relatively reliably, but the inner packaging material is cleaved linearly, so that the laver is inadvertently broken when the inner packaging material is cleaved. There is a risk.
Moreover, opening with the cut tape is merely a means for cutting the outer packaging material and the inner packaging material, and if the packaging material is not pulled sideways after the cutting, the cooked rice processed food cannot be eaten. Eating was troublesome.

In addition, the outer packaging material and the inner packaging material are formed in a sheet shape, the sealing portion of the peripheral portion as described above is not formed, and the inner packaging material is pulled out as it is without using the cut tape, and the laver and the cooked rice are combined. In this case, the inner packaging material is in contact with the cooked rice and cannot be pulled out smoothly due to resistance, as in the case of the above bag-shaped packaging material. It is not always easy to realize.
JP 2000-62835 A JP 2002-166968 A

  The present invention has been made in view of the above points, and it is not necessary to use an opening means such as a cut tape while the outer packaging material and the inner packaging material are both sheet-like packaging materials. It is an object of the present invention to provide a packaged food for cooked rice food that can extract the inner packaging material without receiving resistance due to contact and that can be smoothly and reliably opened.

The present invention has been made to solve such a problem, and the invention according to claim 1 is characterized in that laver is interposed between the sheet-like outer packaging material and the sheet-like inner packaging material, and the rice is included in the inner packaging material. In the packaging material for cooked rice processed food, the inner packaging material is folded back twice into a cooked rice side sheet and a laver side sheet, and the tip of the folded laver side sheet is the outer packaging material The side of the cooked rice sheet and the side of the outer packaging material that are parallel to the drawing direction of the seaweed side sheet are sealed. The width of the laver side sheet of the material is formed narrower than the width of the cooked rice side sheet and the outer packaging material so as not to be sealed together with the cooked rice side sheet and the outer packaging material, and at least half the width of the cooked rice side sheet More than formed It is characterized in that is.
The invention described in claim 2 is characterized in that, in the invention described in claim 1, the width of the laver side sheet of the inner packaging material is formed wider than the width of the laver.

  In the present invention, the inner packaging material is folded back twice between the cooked rice side sheet and the nori side sheet, and the nose side of the folded nori side sheet is exposed to the outside of the outer packaging material and the nori side sheet The side of the rice side sheet parallel to the drawing direction of the nori side sheet and the side of the outer packaging material are sealed, and the width of the nori side sheet of the inner packaging material is The outer packaging material and the cooked rice side sheet are formed to be narrower than the width of the cooked rice side sheet and the outer packaging material so as not to be sealed together with the side sheet and the outer packaging material, and the laver side sheet is pulled out. In this case, the outer packaging material and the cooked rice side sheet are not displaced from each other. Therefore, when the tip of the nori side sheet is pulled outward, an external force is efficiently applied to the starting point of the inner packaging material, and the nori side Shi There is an effect that it is possible to perform bets withdrawal work reliably.

  In addition, the laver side sheet is not thin like a cut tape, for example, and is formed at least half the width of the cooked rice side sheet, so even if the cooked rice side sheet is not cut straight, it is divided in the middle Therefore, it can be opened over the entire longitudinal direction of the cooked rice side sheet.

  In particular, when the laver side sheet is formed wider than the laver width, the width of the opening formed in the cooked rice side sheet by pulling out the laver side sheet is almost the same as that of the laver side sheet and is larger than the laver side sheet. Therefore, as soon as the cooked rice sheet is opened, the cooked rice will immediately merge with the seaweed, and there is no need to peel the packaging material sideways like the conventional means of cutting with a cutting tape. The effect is that you can eat rice with nori as it is.

Hereinafter, embodiments of the present invention will be described.
(Embodiment 1)
The packaging material of this embodiment is a packaging material for hand-rolled sushi, and is composed of one outer packaging material 1 and two inner packaging materials 2 and 3.

The outer packaging material 1 is made of a polypropylene film, and is formed in a planar rectangle as shown in FIG.
One of the inner packaging materials 2a is also made of a polypropylene film, but its shape is different from that of the outer packaging material 1, and as shown in FIG. 2, it can cover the side of the cylindrical rice of hand-rolled sushi. Moreover, it has the protrusion parts 4 and 4 which protrude outward from both sides, and the whole is formed in the substantially T shape.

The inner packaging material 2a is folded back twice as described later at the time of packaging, but is integrated with the cooked rice side sheet 5 in contact with the cooked rice side and the laver side sheet 6 in contact with the laver side. It is structured. The cooked rice side sheet 5 is a wide portion having the protrusions 4, 4, and the laver side sheet 6 is a narrower portion than the cooked rice side sheet 5. Then, in the vicinity of the boundary portion between the laver side sheet 6 and the cooked rice side sheet 5, two cuts 18 and 18 are formed in the direction of the cooked rice sheet 5. The width between the two cuts 18 and 18 is the same as the width of the laver side sheet 6.
The other inner packaging material 3a is also made of a polypropylene film, but there are no projecting portions 4 and 4 like the one inner packaging material 2a. However, the other inner packaging material 3 a is also composed of a laver side sheet 7 having the same width as the laver side sheet 6 of the one inner packaging material 2 a and a cooked rice side sheet 8 wider than the laver side sheet 7. Also in the other inner packaging material 3a, two cuts 19 and 19 are formed in the vicinity of the boundary portion between the laver side sheet 7 and the cooked rice sheet 8 in the direction of the cooked rice sheet 8. The width between the cuts 19, 19 is the same as the width of the laver side sheet 7.
In FIG. 4, 9 shows the laver interposed between the outer packaging material 1 and the inner packaging materials 2a and 3a, and the laver 9 is formed narrower than the laver side sheets 6 and 7 of the inner packaging materials 2a and 3a. Has been.

  As shown in FIGS. 5 to 8, the packaging material of the present embodiment has a nori 9 placed on the outer packaging material 1, and the inner packaging material 2 a that is double-folded on the nori 9. It is configured by placing 3a. More specifically, the inner packaging materials 2a and 3a are double-folded so that the folded portions 10 and 11 overlap in the vicinity of the center as shown in FIG. And the lower side is formed as a laver side sheet in contact with the laver. And the front-end | tip parts 20 and 21 of the seaweed side sheets 6 and 7 protrude on the outer side rather than the front-end | tip part of the cooked rice side sheets 5 and 8, and are made into the bare state. Thereby, the nori side sheets 6 and 7 can be pulled outward.

  Furthermore, as shown in FIGS. 5, 7, and 8, the outer packaging material 1 and the side portions of the cooked rice side sheets 5 and 8, the portion in the direction parallel to the pulling direction of the laver side sheets 6 and 7, that is, the outer packaging material 1 and the side portions in the longitudinal direction of the cooked rice sheets 5 and 8 are sealed by heat to form a seal portion 12. And since the outer packaging material 1 and the cooked rice side sheets 5 and 8 are sealed by the side part of a longitudinal direction by this sealing part 12, although it is set to the fixed state which does not move mutually, the laver side sheet 6 , 7 are formed to be narrower than the outer packaging material 1 and the cooked rice sheets 5, 8, so that they are movable so as to grip and pull out the tip portions 20, 21.

  And when packaging the cylindrical rice for hand-rolled sushi with the packaging material which consists of such a structure, as shown in FIG.9 and FIG.10, the position which has the protrusion parts 4 and 4 of one inner packaging material 2a In addition, the cylindrical cooked rice 13 is placed on the cooked rice side sheet 5, the side portions of the cooked rice 13 are covered with the protruding portions 4, 4, and the packaging material is wrapped around the cooked rice 13 in that state and packaged (not shown). ) Further, although not shown, a label or the like is attached to the wound end. Thereby, hand-rolled sushi is wrapped with the packaging material.

On the other hand, when eating cooked rice, the label is peeled off, the wrapped packaging material is developed, and the state shown in FIGS. 9 and 10 is obtained again.
Then, when the tip portions 20 and 21 of the laver side sheets 6 and 7 are pulled outward, the vicinity of the folded portions 10 and 11, that is, the cuts 18 and 19 are formed as shown in FIGS. 11 and 12. The inner packaging materials 2a and 3a are torn from the portion as the starting point of cleavage, whereby the laver side sheets 6 and 7 can be pulled outward. Further, when the laver side sheets 6 and 7 are pulled out, the film constituting the cooked rice side sheet 5 is torn, thereby opening the upper surface side of the inner packaging materials 2a and 3a and forming the opening 14. .

  In this case, since the outer packaging material 1 which is a portion parallel to the pulling direction of the laver side sheets 6 and 7 and the side portions in the longitudinal direction of the cooked rice side sheets 5 and 8 are sealed, the seal portion 12 is formed. The outer packaging material 1 and the cooked rice side sheets 5 and 8 are fixed, and the outer packaging material 1 and the cooked rice side sheets 5 and 8 may be misaligned when the laver side sheets 6 and 7 are pulled out. Therefore, when the end portions 20 and 21 of the laver side sheets 6 and 7 are pulled outward, the cleavage starting points in the vicinity of the turned-up portions 10 and 11, specifically, the cuts 18 and 19 are formed. External force is efficiently applied to the portion, and the laver side sheets 6 and 7 can be pulled out reliably.

  Moreover, since the laver side sheets 6 and 7 are not as narrow as the cut tape and are formed wider than the laver 9 width, the films constituting the cooked rice side sheets 5 and 8 are not cut straight. Even if it is, there is little possibility that it will be divided in the middle, and therefore the opening 14 can be formed by opening over the entire longitudinal direction of the cooked rice sheets 5, 8.

  Furthermore, since the laver side sheets 6 and 7 are formed wider than the laver 9 width, the width of the opening 14 formed in the cooked rice side sheets 5 and 8 by pulling out the laver side sheets 6 and 7 is also the laver. It is almost the same as the side sheets 6 and 7 and can be made wider than the seaweed 9. Therefore, when the cooked rice side sheets 5 and 8 are opened, the cooked rice is immediately merged with the seaweed. Thus, the work of peeling the packaging material sideways is not necessary, and the rice with nori can be eaten as it is.

(Embodiment 2)
Next, another embodiment will be described with reference to FIGS. Also in this embodiment, the packaging material is comprised by the one outer packaging material 1 and the two inner packaging materials 2b and 3b similarly to the said Embodiment 1, and is common in Embodiment 1 by this point. However, in this embodiment, as shown in FIG. 13, the outer packaging material 1 and the two inner packaging materials 2b and 3b are integrally connected to each other, and in this respect, the outer packaging material 1 and the two inner packaging materials 2b, This is different from Embodiment 1 in which the three packaging materials 3b are all separate bodies.

In this embodiment, as shown in FIG. 14 and FIG. 15, one substantially T-shaped inner packaging material 2b having protrusions 4 and 4 is located at the upper part, and the entire width is the same as that of the one inner packaging material 2b. The entire inner packaging material 3b having a narrow width is positioned at the center, and the outer packaging material 1 wider than the other inner packaging material 3b is positioned at the lower portion, so that the whole is folded into a substantially Z-shape.
The connecting portion 15 between one inner packaging material 2b and the other inner packaging material 3b is bent as it is, but the connecting portion 16 between the other inner packaging material 3b and the outer packaging material 1 is shown in FIG. It has been cut as shown.

In the present embodiment, the entire inner packaging material 2b is formed as a cooked rice side sheet, and the entire other packaging material 3b is formed as a laver side sheet. In this respect, the respective inner packaging materials 2b, 3b It differs from Embodiment 1 in which both the cooked rice side sheet | seat and the laver side sheet | seat are formed.
Due to such a difference, in the first embodiment, each of the inner packaging materials 2b and 3b is configured to be pulled out in the opposite direction, whereas in the present embodiment, the outer packaging material 1 and the other inner packaging material. The tip 22 of 3b is gripped and pulled out in only one direction as shown in FIG.

  Also in the present embodiment, the side part in the longitudinal direction of the outer packaging material 1 and the inner packaging material 2b corresponding to the cooked rice side sheet, which is a portion parallel to the pulling direction of the inner packaging material 3b that is the nori side sheet, is sealed and sealed. Since the portion 12 is formed, the outer packaging material 1 and the inner packaging material 2b are in a fixed state, and the outer packaging material 1 and the inner packaging material 2b may be misaligned when the other inner packaging material 3b is pulled out. Therefore, when the front end portion 22 of the inner packaging material 3b is pulled outward, an external force is efficiently applied to the cleavage start point in the vicinity of the connecting portion 15, and the inner packaging material 3b can be pulled out reliably. .

  In addition, the inner packaging material 3b is formed wider than the laver 9 and is less likely to be divided in the middle. The width of the opening 14 to be formed can be made wider than that of the seaweed 9, and the effects similar to those of the first embodiment are obtained, such as the formation of the opening 14 allows the cooked rice to immediately merge with the seaweed.

(Embodiment 3)
In this embodiment, the inner packaging materials 2c and 3c are connected in series, but the outer packaging material 1 is separate from the inner packaging materials 2c and 3c. Therefore, in the present embodiment, the entire packaging material is composed of two films, which is different from both the first embodiment composed of three films and the second embodiment composed of one film.

In this embodiment, as shown in FIGS. 17 and 18, the root portion 23 of the outer packaging material 1 is folded back and sealed to the inner packaging material 2 c by the seal portion 17. Moreover, the point which the side part of the longitudinal direction of the outer packaging material 1 and the inner packaging material 2c is sealed and the seal part 12 is formed is the same as that of Embodiment 2.
Therefore, although not shown in the drawings, also in the present embodiment, when the inner packaging material 3c is pulled out, the seal portion 12 and the seal portion 17 are formed in a portion in a direction parallel to the pulling direction. There is a similar effect.

(Embodiment 4)
In the present embodiment, as shown in FIG. 19, a large outer packaging material 1 is used, and inner packaging materials 2 d and 3 d having the same structure as in the first embodiment are installed on the outer packaging material 1. Like the inner packaging materials 2a and 3a of the first embodiment, the inner packaging materials 2d and 3d are double-folded so that the folded portions 10 and 11 overlap in the vicinity of the center. It is configured integrally, and is installed on the outer packaging material 1 by sealing both side edges with the seal portion 12.

Also in the present embodiment, the tip portions 20 and 21 of the laver side sheets 6 and 7 protrude outward from the tip portions of the cooked rice sheets 5 and 8 and are in a bare state. Therefore, as in the first embodiment, by pulling the tip portions 20 and 21 of the nori side sheets 6 and 7 outward, the inner packaging materials 2d and 3d are torn, and the nori side sheets 6 and 7 are pulled outward. By pulling out the laver side sheets 6 and 7, the top surfaces of the inner packaging materials 2d and 3d are opened and the laver and cooked rice are combined.
In the present embodiment, cooked rice or the like covered with the inner packaging materials 2d and 3d is further packaged in the outer packaging material 1 in a so-called purse-like state, which is different from the above embodiments.
Instead of the inner packaging material having the structure as in the first embodiment, the large outer packaging material 1 as in the present embodiment is replaced by the inner packaging material having the structure as in the second embodiment or the inner packaging material as in the third embodiment. It is also possible to wrap it in a drawstring state.

(Other embodiments)
In addition, although each said embodiment demonstrated the case where a packaging material was applied to hand-rolled sushi, it is also possible to apply not only to hand-rolled sushi but also to a rice ball. Therefore, it is not a condition that the protrusions 4 and 4 are formed on the inner packaging material as in the first to third embodiments.

  Further, in each of the above embodiments, the outer packaging material 1 and the inner packaging materials 2a, 2b, 2c, 2d, 3a, 3b, 3c, and 3d are made of polypropylene film. The material is not important.

  In the present invention, the outer packaging material 1 and the inner packaging materials 2 and 3 are mainly composed of a synthetic resin film, but can be composed of paper other than the synthetic resin film.

For example, in the packaging materials shown in FIGS. 21 and 22, the inner packaging materials 2e and 3e are made of a synthetic resin film, while the outer packaging material 1 is made of cardboard. The inner packaging materials 2e and 3e are folded in half in the same manner as in the second and third embodiments, and are formed as a cooked rice side sheet and a laver side sheet, respectively. It is attached on the outer packaging material 1.
As in the second and third embodiments, the leading end 22 of the inner packaging material 3e is bare, and the inner packaging is a cooked rice side sheet while grasping the leading end 22 and pulling out the inner packaging material 3e which is a laver side sheet. The material 2e is opened and the cooked rice and laver are combined.
In the present embodiment, the outer packaging material 1 is made of cardboard and has a shape-retaining function for holding the bottom of cooked rice such as rice balls, but it is not flexible like a synthetic resin film, so rice with seaweed To wrap the whole, a packaging material such as a synthetic resin film is separately required.

Furthermore, in the present invention, the main purpose is to make the width of the laver side sheet wider than the width of the laver, but making it wider than the width of the laver is not an essential condition for the present invention.
However, even if the cooked rice side sheet is not cut straight, there is little possibility of being divided in the middle, so that the laver side sheet is not narrow so that it can be opened over the entire longitudinal direction of the cooked rice sheet, It is necessary to be formed at least half the width of the cooked rice sheet. From this viewpoint, the nori side sheet is preferably 2/3 or more of the width of the cooked rice side sheet, more preferably 3/4 or more, and most preferably wider than the width of the nori.

  The cooked rice food packaging material of the present invention is a packaging material for packaging cooked rice foods such as hand-rolled sushi and rice balls. Further, the present invention is widely applied to a packaging material for cooked rice foods for packaging in a state where cylindrical rice for hand-rolled sushi or rice for rice balls is in contact with the inner packaging material.
