The packaged rice balls described in Patent Document 1 and the like can cut the package with a cut tape, remove the package without touching the rice ball main body, and take out the rice balls wrapped in laver. Moreover, since the seaweed is not in contact with the onigiri body when packaged, it can be kept dry.

However, when a triangular rice ball is packaged in a packaging body such as Patent Document 1, an ear portion in which a film protrudes at each corner of the triangle is formed. And the ear | edge part cannot be completely sealed only by folding. While the packaging rice balls are placed at the storefront, foreign objects such as insects may enter the inside through the opening of the ear. In particular, during summer nights, insects tend to enter convenience stores, and the insects often enter rice balls, resulting in complaints.

Therefore, it is conceivable to seal the ears at the three corners. The two corners on the bottom can be folded back with an adhesive tape or seal. However, there is a tip of the cut tape at the apex, and if a sticker or the like is attached thereto, the tip of the cut tape cannot be picked out.

Moreover, in order to open a packaging rice ball of Patent Document 1 or the like, after cutting the package vertically with a cut tape, the package must be further pulled out to the left and right.

In the invention of Patent Document 2, a half cut is formed in the outer sheet along the longitudinal direction, and the dividing start portion is provided in the middle portion in the longitudinal direction, so that it can be opened from the lower side. Moreover, since the perforation and the half cut are provided also in patent document 3 and patent document 4, it can open along it. However, in any case, it is necessary to provide a half cut from the top to the bottom along the center line of the package.

Long half-cuts must be formed at a certain depth. If it is too shallow, it will be difficult to open, and if it is too deep it will penetrate, so outside air will enter the interior. It is not easy to process a thin film while maintaining such conditions. Furthermore, the thickness of the film also varies to some extent, and the difference in thickness must be large at long distances. Strict conditions cannot be maintained simply by increasing the accuracy of the cutting process.

An object of the present invention is to provide a gripping rice wrapping material, a gripping rice wrapping material, and a wrapping gripping rice that can be easily and accurately manufactured and can be easily opened without using a cut tape.

In order to solve the above-mentioned problems, the packaging material for hand-grip rice of the present invention is formed and packaged on a packaging sheet made of a directional plastic film whose crack progresses in a specific direction, and along the crack progressing direction. It has a half-cut portion with a length corresponding to the thickness of the rubbing rice. And, a substantially rectangular outer sheet made of a directional plastic film in which cracks progress in a specific direction, an inner sheet facing the outer sheet, and a laver sheet placed between the outer sheet and the inner sheet A half-cut portion having a length corresponding to the thickness of the hand-grip rice formed and packaged on the outer sheet along the crack progressing direction can also be provided.

The raw material for packaging rice for gripping rice according to the present invention is made of a directional plastic film in which cracks progress in a specific direction as a raw material, and a continuous sheet having a constant width extending along a direction perpendicular to the crack progress direction, along the crack progress direction. A half-cut portion having a length corresponding to the thickness of the gripping rice formed and packaged on the packaging sheet is provided, and the half-cut portions are provided at a predetermined cycle.

Further, the packaged rice of the present invention is a rice cooked packaged by a packaging material, and the rice noodles have a first surface and a second surface parallel to each other, and a bottom surface formed between the first surface and the second surface. The packaging material has a substantially rectangular packaging sheet made of a directional plastic film whose crack progresses in a specific direction, and the thickness of the gripping rice formed and packaged in the packaging sheet along the crack progressing direction. A half-cut portion having a corresponding length is provided, and the half-cut portion is located on the bottom surface of the grip rice. The nigiri rice has a substantially triangular first surface and a second surface that are parallel to each other, and the packaging material is a substantially rectangular outer sheet made of a directional plastic film whose crack progresses in a specific direction, and an outer surface. It has an inner sheet facing the sheet, and a laver sheet placed between the outer sheet and the inner sheet, and wraps the rice cake while folding the packaging material into a substantially triangular shape along the outer shape of the rice bowl. You may form a sealing part in the ear | edge part of the packaging material formed in an apex part. Alternatively, the packaging material may have a substantially rectangular bag shape.

In this invention, since the half-cut portion is provided with a length corresponding to the thickness of the gripping rice, it is possible to easily make a packaging material having a uniform half-cut depth. Therefore, it can seal reliably and can be opened easily.

It is a perspective view which shows the packaging material original fabric for nigiri rice. It is a top view which shows 1 cycle worth of packaging material raw materials for nigiri rice. It is a perspective view which shows the state which put the grip rice main body in one cycle of the packaging material raw material for gripping rice. It is a perspective view which shows the 1st example of packaging noodles. It is a top view which shows the example of the packaging material for nigiri rice. It is the bottom view. It is the same AA sectional view. It is a perspective view which shows the state which put the grip rice main body on the packaging material for gripping rice. It is a perspective view which shows the 2nd example of packaging noodles.

An embodiment for carrying out the present invention will be described with reference to the drawings. First, the first embodiment will be described. FIG. 1 is a perspective view showing a raw material for packaging material for nigiri rice. This gripping material packaging material 10 is made of a plastic film for food packaging. And this plastic film has directionality. That is, when a plastic film is torn, it has a property that a crack progresses in a specific direction. In the present invention, this direction is the crack progress direction. Such directional plastic films are used as materials for food packaging materials. The continuous sheet 11 continues for a long time along the direction perpendicular to the crack propagation direction.

The continuous sheet 11 is provided with a half cut portion 3 along the crack progressing direction. And the length of the half cut part 3 is set so that it may correspond to the thickness of the gripping rice to be packaged. Therefore, the half cut which continues greatly exceeding the thickness of the noodles is not included in the half cut part in this invention. In this example, the half-cut portion 3 is repeatedly provided with a predetermined period R. In addition, the half cut part 3 shall be provided in the lower surface. This gripping material packaging material 10 can be provided as a roll wound around a bobbin.

In FIG. 1, the wavy line repeatedly represented by the period R is a cut line 12 that is a cutting position. When the noodles are packaged, they are sequentially cut along the cut line 12. Thus, what was cut out with the length R becomes one sheet of packaging material for hand-grip rice in this embodiment. FIG. 2 is a plan view showing one cycle of the raw material for packaging material for noodles.

The half cut portion 3 is provided at an intermediate position in the length direction. Also in the width direction, it may be placed near the center, but in this example, it is placed at a position shifted from the center line. This position corresponds to the position where the bottom surface of the gripping rice is placed during packaging, and is related to the position of the backrest when the pillow package is formed.

Next, a method for wrapping noodles using this nigiri wrapping material packaging 10 will be described. FIG. 3 is a perspective view showing a state in which the hand-grip rice x is placed in one cycle of the raw material 1 for hand-grip packaging material, and shows a packaging method.

The noodles x is placed on the half-cut portion 3 for one cycle at the tip of the nigiri wrapping material blank 1. Here, the half cut is provided on the lower surface of the sheet. The gripping rice x is placed in the direction along the length direction of the continuous sheet, and the half-cut portion 3 is along the thickness direction of the bottom surface of the gripping rice x.

And while cut | disconnecting along the first cutting line, the pipe | tube is formed so that the edge | side A and edge | side B which were the side edges of the packaging material raw material 1 for gripping rice may mutually match | combine, a grip rice wrap x. Side A and side B are joined together and connected by thermocompression bonding or the like to form a backrest. Further, the ends of the cylinders formed by the sides C and D are also sealed by thermocompression bonding or the like. In this way, a pillow package is formed, in which the hand-grip rice x is stored, and the hand-grip rice can be made.

In this example, it is suitable to use for rice noodles with seaweed already wrapped in rice, or rice with nori seaweed seasoned with seasoning.

FIG. 4 is a perspective view showing a first example of packaged rice, and shows an example of packaged rice produced by the packaging material and the packaging method described above. The noodles x have a first surface x1 and a second surface x2 that are parallel to each other, and a bottom surface x3 that is formed between the first surface x1 and the second surface x2. In this example, the first surface x1 and the second surface x2 are substantially rectangular, and the side portions have a slight roundness. The whole is a rectangular plate-shaped nigiri. Nori is already wound on the first surface x1 and the second surface x2. There is cooked rice in the seaweed, and the cooked rice contains ingredients such as meat and vegetables. Nori seaweed is not wound on the bottom surface x3 and the top surface x4 that is parallel to the bottom surface x4.

The packaging material has a substantially rectangular bag shape, and a backrest 21 is horizontally formed along the rectangular first surface x1 or second surface x2. The packaging material is made of a directional plastic film, and the crack progressing direction is along the thickness direction at the bottom surface x3, and along the height direction at the first surface x1 and the second surface x2. And since the half cut part 3 is along the thickness direction of the bottom face x3, it will be along the crack advancing direction. Moreover, the half cut part 3 is located in the approximate center in the length direction of the bottom face x3.

The opening method of this packaged rice is demonstrated. Open both sides of the packaging by pulling it to the left and right. In particular, it is easy to open by picking and pulling the vicinity of the lower corner. When this tensile force is applied, first, the half-cut portion 3 on the bottom surface x3 is cut open. In the present invention, since the half-cut portion 3 is short, it can be accurately formed to an appropriate depth, and is not opened by a weak force applied for any reason other than at the time of opening. Is cut open. Thus, the central portion of the bottom surface x3 is separated into the left and right.

When all the half-cut portions 3 are cut open, the crack progresses to the lower end in the center of the first surface x1 and the second surface x2. Furthermore, if the pulling is continued, the crack progresses upward on the first surface x1 and the second surface x2. Since the crack progressing direction is along the height direction in the first surface x1 and the second surface x2, the crack progresses almost upward. Thus, the bottom surface side of the packaging material is greatly opened, and the nigiri rice x is exposed and can be eaten.

Next, a second embodiment of the present invention will be described. FIG. 5 is a plan view showing an example of a packaging material for noodles, FIG. 6 is a bottom view thereof, and FIG. 7 is a cross-sectional view taken along the line AA. The packaged rice packaging material 1 includes a substantially rectangular outer surface sheet 2, an inner surface sheet 4 facing the outer surface sheet 2, and a laver sheet 5 placed between the outer surface sheet 2 and the inner surface sheet 4. This is a package of non-rolled seaweed rice, opened and removed the packaging material so that it can be rolled up with seaweed wrapped. Already popular. The outer sheet 2 is made of one sheet. On the other hand, the inner sheet 4 is made of two sheets 4a and 4b, and the two sheets 4a and 4b overlap each other with a predetermined width, but the overlapping portion is not bonded. Further, the edges of the outer sheet 2 and the inner sheet 4 are connected along the four sides of the outer sheet 2.

The outer sheet 2 is made of a directional plastic film whose cracks progress in a specific direction. The crack progressing direction is along the longitudinal direction of the outer sheet 2. And the half cut part 3 is provided in the center vicinity of the outer surface sheet 2 along the crack advancing direction. The length of the half cut part 3 is equivalent to the thickness of the hand-grip rice to be packaged. The half cut is formed on the outer surface of the outer sheet 2.

Note that the outer sheet 2 and the inner sheet 4 do not have to be completely rectangular. For example, the corners of the four corners may be cut off so that folding is reduced in packaging.

Next, a method for wrapping noodles using the package for nigiri rice of this example will be described. FIG. 8 is a perspective view showing a state where the main body of the handful rice is placed on the handgrip rice packaging material. The packaging material 1 for nigiri rice is placed so that the inner sheet 4 faces upward. And laver is put on the center part of this packaging material 1 for nigiri rice, and the main body x of rice is put on it.

The nigiri rice packaged in this example is a triangular rice ball. The nigiri rice has a substantially triangular first surface x1 and second surface x2 that are parallel to each other, and a bottom surface x3 that is formed between the first surface x1 and the second surface x2. The seaweed rice body x is not wrapped with nori.

The thickness direction of the grip body main body x is aligned in the direction along the half cut portion 3, and the bottom surface x3 of the grip rice main body x is placed at a position where the half cut portion 3 is located. Next, the handgrip rice main body x is wrapped along the shape of the handgrip rice main body x while folding the handgrip rice packaging material 1. Adhere adhesive tape or a sticker on the folded part. Thus, the triangular rice balls are almost wrapped. At the three corners of the triangle, ears are formed such that the folded portions of the packaging material protrude.

Then, the lower two ears 31 are sealed by heat welding or the like. Further, the apex ear 32 is also sealed by heat welding or the like.

In the two ear portions 31 at the lower portion of the triangle, there is no particular problem in forming the sealing portion. On the other hand, in the ear | edge part 32 of the vertex part, the sealing part was not able to be provided in the conventional packaging triangular rice ball because there was a front-end | tip part of a cut tape. This is because if the seal, adhesive tape, or the like is attached to the apex, the tip of the cut tape cannot be grasped, and the packaging member cannot be opened. However, no cut tape is used in the packaged rice for packaged rice and the packaged rice for cooking of the present invention, and there is nothing that hinders the formation of the sealing portion 33 in the ear portion 32 at the apex portion.

Thus, since the sealing portion 33 is provided in the apex ear portion 32, foreign matters such as insects are prevented from entering from the apex portion, which is hygienic.

FIG. 9 is a perspective view showing a second example of the package gripping rice. As above-mentioned, the example of the packaging handmade rice made with the packaging material for gripping rice shown in FIGS. 5-7 and the packaging method shown in FIG. 8 is shown.

The packaging material 1 is made of a directional plastic film, and the progress direction of the crack is along the thickness direction at the bottom surface x3 and along the height direction at the first surface x1 and the second surface x2. And since the half cut part 3 is along the thickness direction of the bottom face x3, it is along the crack progressing direction.

Next, the opening of the package gripping rice 30 will be described. Opening can be performed simply by pulling the packaging material left and right. For example, holding the packaging member such as the ears 32 at both corners on the lower side, and pulling it left and right. When this tensile force is applied, first, the half-cut portion 3 on the bottom surface x3 is cut open. Thus, the central portion of the bottom surface x3 is separated into the left and right.

When all the half-cut portions 3 are cut open, the crack progresses to the center of the bottom of the first surface x1 and the second surface x2. Furthermore, if the pulling is continued, the crack progresses upward on the first surface x1 and the second surface x2. Since the crack progressing direction is along the height direction in the first surface x1 and the second surface x2, the crack progresses almost directly toward the apex.

The inner sheet 4 is also divided into left and right. If pulled as it is, the inner sheet 4 is removed together with the outer sheet, and a triangular rice ball wrapped in the laver 4 appears.

Conventional packaging triangular rice balls required two steps: drawing the cut tape to cut the external film and drawing the packaging member left and right. However, the packaging triangle rice ball of the present invention can be opened by only one operation of pulling the packaging material left and right.
