Description

  The present invention relates to a method for packaging cooked rice food, and particularly to an internal packaging technique for rice ball products made of cooked rice and dried seaweed.

  Traditionally, onigiri products that have been manufactured and sold in large quantities as market products have been separated with a plastic film so that the cooked rice and dried seaweed do not come into direct contact with each other in order to maintain the shape of the seaweed so that it does not change its hardness until the time of eating. Internal packaging is provided.

  For example, in a laver roll type, a rectangular plastic film is wound inside in a state in which cooked rice and dried laver are separated, and in this case, after removing the packaging material for sanitary storage, the plastic film Needed to be removed from the dried seaweed and rewound on cooked rice. (For example, see Utility Model Document 1)

  In addition, the triangular rice ball wraps the cooked rice inside with a triangular pyramid outer wrapping material and a triangular pyramid shaped plastic film for inner wrapping. After tearing at the center, it was necessary to remove the plastic film for internal packaging from side to side. (For example, see Patent Document 1)

However, according to the above-described prior art, in the case of laver roll type rice ball products, it is necessary to properly perform the operation of once opening the plastic film for internal packaging and the operation of joining separately exposed cooked rice and dried laver. Moreover, it was troublesome, and further, there was often a defect that the dried laver was damaged when the plastic film for inner packaging was opened.
In addition, the current nori-waki type rice ball products that are completely exposed when eating are not only hard to eat due to the absorption of moisture, but also have the disadvantage of falling apart and falling.

  Also, in the case of the three-stroke rice ball, the operation of peeling the plastic film for internal packaging to the left and right while adjusting the speed while taking care not to damage the dried seaweed is troublesome. In some cases, the dried laver that is torn inside the triangular pyramid may be damaged, and it becomes an organic substance that causes eutrophication when discarded, which is not preferable for environmental protection.

  As a result of diligent research to solve the above-mentioned problems related to rice ball products, the present inventors wrapped rice with two portions of a plastic film for inner packaging folded, and dried laver on it. By wrapping, the cooked rice and dried seaweed can be joined quickly and more appropriately with a simple operation by simply pulling both ends of the plastic film for internal packaging. In addition, since the exposed part is minimized when eating, it does not change the hardness of the product due to moisture absorption, is hygienic, and is also used when discarding plastic film for internal packaging after use. The inventors have reached the invention of a novel packaging method that contributes to environmental eutrophication measures because no seaweed damage is mixed.

  In addition, by extending both ends of the plastic film for internal packaging of the present invention and developing it to the role of an outer member, it is possible to unify packaging materials for rice ball products, making it easy to dispose and retain It also led to improvements.

  In the first aspect of the present invention, a packaging shape having a double-side structure is assembled, in which two intermediate portions of a single plastic film whose both ends are positioned at the lower part of the outer side are folded back to be the apexes of the upper part. A method for wrapping cooked rice food, characterized in that after the cooked rice is put, dried nori is wrapped around the side surface and an exterior material is attached and fixed to the outermost part.

  The second aspect of the present invention is a plastic film for internal packaging in which both ends are connected and integrated in a ring shape as an internal packaging plastic film for isolating cooked rice 1 and dried laver 3 in packaging of cooked rice processed food. Use the inner packaging plastic film inner side 2a to cover the cooked rice 1 and place the inner packaging plastic film outer side 2b so as to be folded, and dry laver 3 over the inner packaging plastic film inner side 2a and the inner packaging plastic film outer side 2b. It is the packaging method of the cooked rice processed food characterized by covering.

  The third aspect of the present invention is that the inner packaging film 2 is detached from the cooked rice 1 and the dried nori 3 by pulling the inner packaging plastic outer 2b in the direction A, and the cooked rice 1 and the dried nori 3 are in contact with each other. It is the packaging method of the processed rice food characterized.

  The third aspect of the present invention is to fold back two intermediate parts of one plastic film which is twice the length of the side surface and has both ends positioned at the lower part of the outer side, respectively, and apex of the upper part. After putting the cooked rice into the packaging shape of the double side structure, wrap the dried nori around the side, and then wrap both ends of the plastic film from the bottom of the side to cover and fix the dried nori However, it is a method for wrapping cooked rice food, which is transported to the top of the top.

  As described above, according to the present invention, the shape of the cooked rice may be a seaweed-rolled rice ball or a triangular rice ball, and can correspond to various shapes such as a round shape and a square shape.

  Moreover, the packaging state can be solved quickly and appropriately.

  Moreover, damage and remaining of dried nori can be eliminated.

  In addition, especially in the case of laver roll type cooked rice, it is possible to bring the cooked rice into contact with the dried laver while sequentially moving the plastic film for inner packaging, so that the hardness change of the laver due to moisture absorption does not occur, Therefore, there is no risk of losing shape when eating.

  In the present invention, the material of the plastic film for internal packaging may be a polyolefin resin, a polyamide resin, or a polyester resin, and the fixing exterior material may be any of plastic, paper, nonwoven fabric, and the like.

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, embodiments of the present invention will be described with reference to FIGS.
The present invention is characterized by a plastic film 2 for internal packaging for isolating cooked rice 1 and dried laver 3.

  At the time of packaging, the cooked rice 1 is covered with a plastic film 2 for internal packaging. At that time, the cooked rice 1 is completely covered with the inner packaging plastic film 2a, and the inner packaging plastic film outer 2b has a function for removing the inner packaging plastic film 2a. There is no need to cover the cooked rice 1 by overlapping the inner side 2a.

  FIG. 2 shows an example in which the laver roll-shaped cooked rice 1a is covered with the inner packaging plastic film 2, and FIG. 4 shows an example in which the triangular rice ball cooked rice 1b is covered with the inner packaging plastic film 2. 2 and 4 are shown in the drawings to represent a state in which the inner packaging plastic film 2 is covered. In actual use, the space 6 is not used but the cooked rice 1 is used as the inner packaging plastic film 2. Covered completely.

  Next, the cooked rice 1 covered with the plastic film 2 for internal packaging is covered with the dried laver 3. At that time, in the case of laver roll type, the dried laver 3 is wound from above the inner packaging plastic film inner side 2a and the inner packaging plastic film outer side 2b (FIG. 2). In the case of a triangular rice ball, the dried nori 3 is covered from the upper side, and the bottom of the dried nori 3 is folded between the inner packaging plastic film inner side 2a and the inner packaging plastic film outer side 2b. . (Fig. 5)

  Next, the cooked rice 1 covered with the dried laver 3 is covered with the exterior material 4. At that time, both the laver roll type and the triangular rice ball are covered with the outer packaging material 4 between the inner packaging plastic film inner side 2a and the inner packaging plastic film outer side 2b from below. (An example in which the package 4 is covered with a triangular rice ball processed rice food is “FIG. 6”, and the case of the nori roll type is also covered.)

  At the time of opening, the exterior material 4 is broken from the notch 5 provided in the exterior material 4 and opened in the direction B and the direction C, and the exterior material 4 is removed.

  Next, when the inner packaging plastic film outer side 2b is pulled in the direction A, the inner packaging plastic film inner side 2a is also pulled so that the inner packaging plastic film outer side 2b is taken, and the inner packaging plastic film 2 is removed. Separation of cooked rice 1 and dried seaweed 3 is eliminated, and it becomes possible to eat. (Examples of opening operation in the case of a triangular rice ball are shown in FIGS. 7 to 9, which are sequentially opened with FIGS. 7, 8, and 9, and in the drawings, opening of the outer packaging 4 and plastic film for internal packaging) (The same applies to the seaweed roll type.)

"Other embodiments"
In the above embodiment, the internal packaging plastic film 2 is removed after the exterior material 4 is removed. However, before the exterior material 4 is removed, the internal packaging plastic film 2 may be removed, and the exterior material 4 is opened in half. Then, a method of removing half of the plastic film 2 for internal packaging may be used.

  Moreover, although the plastic film 2 for internal packaging in a present Example is using the rectangular one sheet | seat film which the both ends were connected and was circular, the plastic film 2 for internal packaging which is not connected at both ends May be used. (Example of plastic film 2 for internal packaging in which both ends are not connected, FIG. 10)

  In this embodiment, the inner packaging plastic film inner side 2a and the inner packaging plastic film outer side 2b are integral films, but the inner packaging plastic film inner side 2a and the inner packaging plastic film outer side 2b are separate films, The inner packaging plastic film inner side 2a has a shape that can easily cover the cooked rice 1, and the inner packaging plastic film outer side 2b does not interfere with the covering of the dried laver 3 and the outer packaging material 4. A thin shape may be used. (Example of the internal packaging plastic film 2 formed by connecting the inner packaging plastic film inner side 2a and the inner packaging plastic film outer side 2b formed of separate films to form a single sheet, FIG. 11)

Moreover, in the packaging method of this invention, the function of the exterior material 4 can be satisfied with the plastic film 2 for internal packaging by extending the plastic film outer side 2b for internal packaging, and covering the dried laver 3.
Moreover, the method of integrating the plastic film 2 for internal packagings and the exterior | packing material 4 which were formed separately may be sufficient. (Fig. 12)
