DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention shown in the drawings will be described below. 1 to 3 show a first embodiment of an onigiri packaging according to the present invention. FIG. 1 is a schematic rear view showing the interior side of the onigiri packaging, and FIG. 2 is shown in FIG. FIG. 3 is a schematic surface view showing the exterior side of the onigiri package, and FIG.
FIG. 2 is a sectional view taken along line AA in FIG. 1.

That is, the onigiri package 1 shown in FIGS. 1 to 3 is composed of an outer film 2 having opening means, and left and right inner films 3 and 4 forming a bag portion 7 in cooperation with the outer film 2. Consists of The opening means is the exterior film 2
Opening strip 5 adhered between the upper and lower ends, and an inverted Y-shaped notch 1 provided at a position where the opening strip 5 is located.
3 are formed. Then, by removing the opening strip 5, the outer film 2 is cut into almost two parts so that the left and right inner films 3, 4 can be split.

In FIG. 1 through FIG.
Is made of a general-purpose film having thermal adhesiveness, and is formed in a vertically long rectangular shape large enough to cover the rice ball 20 for rice balls.

The package film 2 is provided with an opening means, which is formed by the opening band 5 and the cut 13.

The opening strip 5 is disposed and adhered to the center of the outer surface of the exterior film 2 in the short side direction from the upper end to the lower end. At this time, the opening band 5 is
A material having a certain strength that is not easily cut is used. Further, the upper end and the lower end of the opening strip 5 are made to be non-adhesive to the exterior film 2, and the non-adhesive part of the end is formed as a knob 5a. In addition, although the figure which formed the knob part 5a in the upper and lower both ends of the opening strip | belt 5 in the figure was shown, either may be only one. In that case, the knob 5a is formed at the end (the upper end in the figure) on the opening start side, which is the rearmost part in the opening direction X of the opening band 5.

In this case, the method of bonding the bonding portion 5b of the opening strip 5 is not limited. For example, a pressure-sensitive adhesive or an adhesive may be used, or thermal bonding may be used. It is preferable that the adhesive has a certain adhesive strength and can be peeled to some extent. Further, the method of non-adhesion of the knob 5a is not particularly limited. For example, a release agent may be applied to the portion of the exterior film 2 corresponding to the knob 5a, or to both ends of the opening strip 5, or mechanical means may be used. In short, it is sufficient if the knob 5a can be picked and pulled.

At the upper end portion of the portion of the exterior film 2 where the opening strip 5 is located, a cut portion 13 having an inverted Y shape as a whole is provided. The cut 13 is formed by the cut 11 and the streak 12.

The cut 11 is formed in an inverted V-shape so as to expand toward the front side (downward in the drawing) in the opening direction X from the upper end to the lower end. 14 are formed. The cut 11 serves as a trigger for cutting the exterior film 2, and guides the cutting progress so that the cutting direction of the opening band 5 is directed to the opening direction X. For this reason, when the knob 5a on the upper end side is picked and pulled downward in the opening direction X, the opening strip 5 is separated so as to be peeled off from the exterior film 2 up to the cut 11. Subsequently, at a position further in the opening direction X than the cut 11, the opening band 5 is pulled while being adhered to the exterior film 2.
From the opening strip 5 so as to be torn along both side edges of the opening strip 5.

The streak 12 is connected to the center of the cut 11 having an inverted V-shape, and is formed in a straight line extending upward from the center of the cut 11 in parallel with the opening direction X. Due to the presence of the streaks 12, the exterior film 2
To facilitate the division. When the opening strip 5 is removed, the exterior film 2 is cut vertically in a state where the portions above the cuts 11 are connected. In this case, since the presence of the streaks 12 formed in the vertical direction triggers the division of the exterior film 2, the exterior film 2 can be easily pulled to the left and right halves by pulling the left and right ends to the side. It is divided into two parts.

A bag 7 is provided on the entire inner surface of the exterior film 2.
Is formed. The bag portion 7 is formed between the films 2, 3, and 4 by bonding the left interior film 3 and the right interior film 4 to the exterior film 2. The bag 7 can cover the entire surface of the rice 20 on the inner side.

The left and right interior films 3 and 4 are each formed of a general-purpose film having thermal adhesiveness and formed in a vertically long rectangular shape. Here, the width of each of the interior films 3 and 4 is longer than the width of the vertical half of the exterior film 2.

The right interior film 4 has its right end aligned with the right end of the exterior film 2, its upper and lower ends aligned with the upper and lower ends of the exterior film 2, and its left end passes over the opening strip 5. Thus, the right inner film 4 covers the entire area on the inner surface side on the right half of the outer film 2. The right inner film 4 has its right end and a portion extending from the right end of the upper and lower ends to the vicinity of the opening band 5 thermally sealed to the outer film 2 with a predetermined width to be sealed.

The left interior film 3 has its left end aligned with the left end of the exterior film 2, its upper and lower ends aligned with the upper and lower ends of the exterior film 2, and its right end passes over the opening strip 5. Thus, the left interior film 3 covers the entire area on the inner surface side on the left half of the exterior film 2. The left inner film 3 and the portion extending from the left end of the upper and lower ends to the vicinity of the opening strip 5 are thermally bonded to the outer film 2 with a predetermined width and sealed.

In this case, the portion on the left end side of the right interior film 4 and the portion on the right end side of the left interior film 3 are arranged in a non-adhesive state at the center of the exterior film 2 in the short side direction. The polymerized portion is oriented vertically. The opening strip 5 is located at a position corresponding to the overlapping portion of the left and right interior films 3 and 4. Therefore, the bag portions 7 are formed in cooperation with both the interior films 3 and 4 and the exterior film 2, and a space partitioned from the outside is formed inside the bag portion 7.

Since the left interior film 3 and the right interior film 4 do not adhere to each other at the overlapped portion, when the opening strip 5 is removed and the exterior film 2 is cut, the two interior films 3 and 4 are attached to each other. It can be divided in the horizontal direction. In other words, when the opening strip 5 is removed, the exterior film 2 is cut into approximately two parts, so that the left half of the exterior film 2 and the left interior film 3 are integrated by the heat bonding portion 9; The right half portion of the exterior film 2 and the right interior film 4 can be divided into a single unit formed by a thermal bonding unit 10.

At both corners of the upper end, which is the opening start end side of the rice ball wrapper 1, trapezoidal cutouts 8, 8 are provided at the positions of the thermal bonding portions 9, 10. This is optional and does not need to be provided specially. However, it is preferable to provide it when packing rice 20 having a triangular shape.

In order to package the rice 20 for onigiri using the packaging 1 for onigiri configured as described above, first,
For example, laver 6 which is a wrapping material is inserted from the overlapping portion of the left and right interior films 3 and 4 and accommodated in the bag portion 7. Next, rice 20 that is gripped in a triangular shape that is convenient to eat is brought into contact with the inner surfaces of the left and right interior films 3 and 4.

Here, in order to store the laver 6 in the bag 7,
In the manufacturing process of the package 1, after the laver 6 is arranged on the inner surface side of the outer film 2, the left and right inner films 3, 4 are arranged on the inner surface side of the laver 6 in a superposed state, and the four sides of the peripheral edge thereof are arranged. Of these, the portion excluding the polymerized portion may be thermally bonded. In addition, the laver 6 needs to be large enough to cover the entire surface of the rice 20,
Here, a rectangular shape is used so as to match the shape of the space in the bag portion 7.

The rice 20 is covered and positioned on the lower end side of the inner surface of the package 1. First, as shown in FIG. 4, the rice 20 is disposed at the center of the package 1 in the short side direction with one top thereof facing downward, and at that time, the rice 20 is placed at the center of the long side direction. It is located at a position more deviated to the lower end side.

Then, the rice 20 is filled with the left and right interior films 3,
4 and the right and left lower parts 17, 18 of the package 1
Bend. First, the lower right part 18 of the package 1 is the rice 2
0 is bent in the direction of a in FIG. 4 along the lower right slope,
The bent portion is brought into contact with rice 20. Similarly, the lower left portion 17 of the package 1 is bent in the direction b in the figure along the lower left slope of the rice 20, and the bent portion is brought into contact with the rice 20.

Next, rice 2 is placed in the upper half of the package.
Cover 0. That is, the upper half of the package 1 is
Is bent in the direction c in FIG. 4 along the upper surface of the rice, and the bent portion is brought into contact with the rice 20 to obtain a state as shown in FIG. Subsequently, the left and right upper portions 15 and 16 of the package 1 are bent. First, the upper right part 16 of the package 1 is
5 is bent in the direction d in FIG. 5 along the lower right slope, and the bent portion is overlapped on the outer surface of the lower right 18. Similarly, the upper left portion 15 of the package 1 is bent in the direction e in the figure along the lower left slope of the rice 20, and the bent portion overlaps the outer surface of the lower left portion 17.

As a result, the package 1 is wrapped so as to cover the entire surface of the rice 20 as shown in FIG. At this time, between the upper left part 15 and the upper right part 16 of the package 1, a seal 19 such as a label is stuck and fixed so as to straddle, so that the package 1 is kept in a state of covering the rice 20. Is done. In this case, as shown in the figure, when a part of the seal 19 is attached so as to also contact the exterior film 2, the package 1
This is preferable because the fixing of the rubber is more complete. FIG. 6 shows the surface on the opposite side of the package 1 shown in FIG.

Next, the operation of the above will be described. When eating the contents packaged in the package 1 as described above, after removing the opening strip 5 and cutting the exterior film 2, the left and right halves of the package 1 are pulled. Then, the contents are exposed in a state where the rice 20 is covered with the laver 6, and the rice balls are completed.

First, in order to open the package 1 in which the rice 20 is packaged in a state in which the seaweed 6 is stored in the bag portion 7, the knob 5 a of the opening band 5 located on the upper end side of the package 1 is opened. This is pulled along the surface of the rice 20 toward the knob 5a on the other side located on the lower end side of the package 1 (in the X direction in FIG. 6). Then, the opening strip 5 is separated so as to be peeled off from the exterior film 2 up to the portion where the cut 13 is located. When the knob 5a is further pulled in the opening direction X further than the notch 13, the tongue 14
Is adhered to the opening strip 5 and is pulled together therewith.

At this time, due to the presence of the cut 11, the tongue portion 14 of the opening band 5 becomes the opening start end, and the cut 11
From the opening strip 5 along the side edge of the opening strip 5 so as to tear the exterior film 2. In other words, the portion of the exterior film 2 corresponding to the adhesive portion 5b is pulled while being adhered to the opening band 5, so that the portion is cut off from the other exterior film 2 and integrated with the opening band 5. Will be removed. As a result, the exterior film 2 is cut almost straight in the vertical direction at the central portion in the short side direction, and is roughly divided into a left half portion and a right half portion while being connected at the upper end.

Thereafter, when the user pulls the right end portion of the right half of the exterior film 2 with the right end apex, the right interior film 4 and the right half of the exterior film 2 bonded by the thermal bonding portion 10 are removed together. It is. At this time, since the right interior film 4 is located between the rice 20 and the laver 6, the right interior film 4 slides on the inner surface with the surface of the rice 20 and on the outer side with the laver 6 while sliding on the right side. Will be moved to.
Therefore, as shown in FIG. 8, the right half of the rice 20 is exposed while being covered with the laver 6.

At this time, the opening direction X
The portion of the exterior film 2 on the rear side is in a state where the left half and the right half are connected, but due to the presence of the streak 12,
Each half can be easily divided.

Next, the seaweed 6 is held by hand in a state pressed against the rice 20 in the right half, and on the other hand, the left end top of the left half of the exterior film 2 is pulled to the left in the same manner as described above. The left interior film 3 and the left half of the exterior film 2 adhered by the adhesion section 9 are removed together. At this time,
Since the left interior film 3 is located between the rice 20 and the laver 6, the left interior film 3 slides on the inner surface with the surface of the rice 20 and moves leftward while sliding on the outer surface with the laver 6. Will be. Therefore, the left half of the rice 20 is exposed while being covered with the laver 6.

As a result, rice 20 can be obtained in a state where rice 20 is entirely covered with laver 6,
Onigiri is completed and can be eaten.

In the above case, the rice 20 is wrapped in a state in which the seaweed 6 is stored in the bag part 7, so that the seaweed 6 does not come into contact with the rice 20 until immediately before eating the rice ball. For this reason, the seaweed 6 is not moistened by the moisture of the rice 20 when in the packaged state, so that the flavor of the seaweed 6 is not impaired. Therefore, a delicious rice ball can be eaten at any time upon opening.

Further, in a state where the left and right interior films 3 and 4 are superimposed on each other in a non-adhesive state, the peripheral edge is adhered to the exterior film 2 and the exterior film 2 is cut into two parts so as to pass through the non-adhered portion. The provision of the opening strip 5 allows the left interior film 3 and the right interior film 4 to be divided when each half of the exterior film 2 is separated. For this reason, the exterior film 2 divided by removing the opening strip 5 can simultaneously separate the interior films 3 and 4 by pulling each half. Moreover, by removing the inner and outer films 2, 3, and 4, the rice ball is completed with the rice 20 covered with the laver 6 at the same time. Therefore, the laver 6 and the rice 20 can be easily combined at the same time as opening, so that the onigiri can be easily eaten without any trouble.

Then, in the above-mentioned onigiri package 1, the outer film 2 can be cut cleanly and securely when opened.

That is, in the portion of the exterior film 2 corresponding to the bonding portion 5b of the opening strip 5 at the opening start end side (upper end), an inverted Y-shape formed by the cut 11 and the streak 12 is formed. By providing the cut portion 13, when the opening strip 5 is removed, it is easy to cut the exterior film 2 in the initial stage of opening. In addition, it is easy to divide each half of the exterior film 2 after cutting.

That is, since the cut 11 of the cut 13 is formed in an inverted V-shape that expands toward the front in the opening direction X and the outer film 2 is provided with the tongue 14,
The tip of 4 is swingable. For this reason, when pulling the opening strip 5, the tongue portion 14 is separated from the portion of the cut 11 from the other portion of the exterior film 2 and is pulled together with the opening strip 5. Therefore, as the opening band 5 advances in the opening direction X, the tongue portion 1
4, the adhesive portion 5b at the site in the opening direction X is pulled in a state of being adhered to the exterior film 2, whereby the portion of the exterior film 2 adhered to the adhesive portion 5b is separated from the other exterior film 2 site. It is torn.

In this case, since the portion of the exterior film 2 corresponding to the bonding portion 5b is pulled and removed integrally with the opening strip 5, the exterior film 2 can be reliably cut. . As a result, the exterior film 2 is reliably cut along the opening strip 5, so that the portion torn from the tongue portion 14 does not meander or taper and is cut, so that a clean cut is possible. Can be realized.

Moreover, since the streaks 12 of the cuts 13 are formed in the vertical direction, it is easy to cut the exterior film 2 from that portion. That is, when the opening strip 5 is removed, the left half and the right half of the exterior film 2 are cut by the cut 11
It is connected at the upper end on the rear side in the opening direction X and is not completely separated. At this time, since the streaks 12 are present in the portion of the remaining exterior film 2 that has not been cut at the site where the opening strip 5 was located, each half of the exterior film 2 is laterally moved. By pulling, the line 12 is easily cut from the site. Therefore, it is easy to divide each half of the exterior film 2 after the opening strip 5 is removed, so that the package 1 can be easily and reliably removed.

Furthermore, when the trapezoidal cutouts 8 are provided at both corners at the upper end of the package 1, the opening strip 5 can be more easily removed.

That is, notches 8 are provided at both corners of the package 1.
By providing 8, as shown in FIG. 7, the overlapping portion G between the upper left portion 15 and the upper right portion 16 at the center in the short side direction can be reduced. For this reason, at the time of opening, since the overlapping portion G does not hinder the advance of the opening band 5, the cutting of the exterior film 2 by the opening band 5 is facilitated, and the separation of the package 1 can be ensured. Become.

The notch 1 in the first embodiment described above.
Modifications of Example 3 are shown in FIGS. That is, the cut portion 13a shown in FIG. 16 is a U-shaped cut 11 that opens in the opening direction X at the upper end of the exterior film 2.
a. The notch 13b shown in FIG.
It is formed by a U-shaped cut 11b opening forward, and has an inverted U shape as a whole.
As described above, the shape of the cut portion is not particularly limited, and the cut portion is provided on the upper end side of the adhesive portion of the opening band,
What is necessary is just to form the tongue part which becomes an opening start end. In addition, it is a matter of course that the cut portion 13a shown in FIG. 16 and the cut portion 13b shown in FIG. 17 may be provided with a vertical streak which makes it easy to divide the exterior film 2. .

Next, a second embodiment will be described with reference to FIGS. 9 is a schematic rear view showing the interior side of the onigiri package, FIG. 10 is a schematic front view showing the exterior side of the onigiri package shown in FIG. 9, and FIG. 11 is a line BB in FIG. It is sectional drawing. That is, FIGS.
The rice ball wrapping body 31 shown in FIG. 5 is obtained by deforming one of the left and right interior films 3 and 4 and the cut portion 13 in the first embodiment. That is, the folded portion 33a is formed in the left interior film 33 used for the illustrated packaging body 31, and the cut portion 43 is formed in an inverted V shape. Since other configurations are the same as those of the first embodiment, detailed description is omitted by attaching the same reference numerals.

9 to 11, the left interior film 33 has a vertically long rectangular shape having a width larger than that of the left interior film 3 in the first embodiment. The left interior film 33 covers the inner surface of the left half of the exterior film 2 in a state where its left end is aligned with the left end of the exterior film 2 and its upper and lower ends are respectively aligned with the upper and lower ends of the exterior film 2. Placed. At this time, the left interior film 33
Of the right interior film 4 is disposed in a non-adhesive and overlapped state on the left side of the inner surface of the right interior film 4.

In the left interior film 33, a portion beyond the left end of the right interior film 4 is folded inward to form a folded portion 33a. In this case, the fold is made to pass over the opening band 5. Then, the left interior film 33 is heat-sealed with a predetermined width to the exterior film 2 at the left end and a portion extending from the left end of the upper and lower ends to the vicinity of the opening strip 5 and sealed.

At the upper end portion of the portion of the exterior film 2 where the opening band 5 is located, a cut portion 43 having an inverted V shape as a whole is provided. The cut portion 43 does not form the stripe 12 in the first embodiment, and is formed by the cut 11 having an inverted V shape. That is, the cut portion 43 does not have to form the stripe 12. In this case, the exterior film 2 can be divided into a left half portion and a right half portion by cutting the opening side body 5 and then pulling the left and right ends to cut from the top of the cut 11. It has become.

Then, the package 3 configured as described above
In the first embodiment, in addition to the operation described in the first embodiment,
The package 31 can be removed without damaging the rice 20.

That is, since the folded portion 33a is formed at the right end of the left interior film 33, when the package 31 on the left half portion is pulled after cutting the exterior film 2, the left interior film 33 is The rice 20 is moved to the left so as to be peeled off.

In other words, when the folded portion is not formed as in the first embodiment, when the left interior film 3 is pulled to the left side of the package 1 on the left half side, the rice 20 is removed.
There is a possibility that the shape of the rice 20 may be broken due to a tensile force acting on the rubbed portion because the rubbed portion moves to the side so as to rub against the surface of the rice 20. According to this modification, when the left half package 31 is pulled to the left, the left interior film 33
Moves on the surface of the rice 20 while peeling from the right end of the folded portion 33a to the left. For this reason, since the pulling force is not applied to the rice 20 when the package 31 is removed, the rice 20 can always be eaten in a well-shaped state.

In the above case, the right interior film 4 is
The right end is located between the left interior film 33 and the exterior film 2 and is not in contact with the rice 20. For this reason, at the time of opening, if the package 31 is divided and then removed from the right half first, it is effective because the right interior film 4 does not rub against the rice 20.

Next, the third embodiment will be described with reference to FIGS.
Shown in 12 is a schematic rear view showing the interior side of the onigiri package, FIG. 13 is a schematic front view showing the exterior side of the onigiri package shown in FIG. 12, and FIG. 14 is a line CC in FIG. It is sectional drawing. That is, FIGS.
4 are the left-side interior film 3 and the right-side interior film 4 of the first embodiment.
And the notch 8 are modified. That is, the left interior film 53 and the right interior film 54 used for the illustrated packaging body 51 are formed with folded portions 53a and 54a, and the cutout 58 is formed in a triangular shape. Since other configurations are the same as those of the first embodiment, detailed description is omitted by attaching the same reference numerals.

In FIGS. 12 to 14, the left interior film 53 has a vertically long rectangular shape larger in width than the left interior film 3 in the first embodiment. The left interior film 53 covers the inner surface of the left half of the exterior film 2 in a state where its left end is aligned with the left end of the exterior film 2 and its upper and lower ends are respectively aligned with the upper and lower ends of the exterior film 2. Placed. Then, the left interior film 53
The left end and the part extending from the left end of the upper and lower ends to the vicinity of the opening strip 5 are thermally bonded to the exterior film 2 with a predetermined width to be sealed.

The right interior film 54 has a vertically long rectangular shape wider than the right interior film 4 in the first embodiment.
