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 package according to the present invention. 1 is a schematic rear view showing the interior side of the onigiri package, FIG. 2 is a schematic front view showing the exterior side of the onigiri package shown in FIG. 1, and FIG. 3 is a line AA in FIG. It is sectional drawing.

In other words, the packaging 1 for rice balls shown in FIGS. 1 to 3 has a packaging film 3 to which a strip 2 for opening is adhered.
And left and right interior films 4 and 5 forming a bag portion 21 in cooperation with the exterior film 3. The left and right interior films 4 and 5 are partially polymerized in a non-adhesive manner, and the peripheral edge excluding the polymerized portion is thermally bonded to the exterior film 3.
At the upper and lower corners of the heat-bonded portions 8 and 9, notches 1 formed of a parallel notch 18 a and an inclined notch 18 b are provided.
8, 18,... Are formed.

In FIG. 1 to 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 3 is provided with an opening means, which is formed by the opening strip 2 and the notch 16. The opening strip 2 is arranged and adhered to the central portion in the short side direction on the inner surface side of the exterior film 3 from the upper end to the lower end thereof. At this time, the opening strip 2 is
A material having a certain strength that is not easily cut is used.

The notches 16 are provided in pairs at the upper and lower ends of the exterior film 3 where the opening strip 2 is located, with the opening strip 2 sandwiched therebetween. In this case, the notches 16, 16 are provided at the upper and lower ends of the exterior film 3, but may be provided at only one of the ends. In other words, the notches 16, 16 only need to be provided at least at the end on the opening start side.

Due to the presence of the notches 16, the end of the opening strip 2 is formed as a knob 2a, which triggers the cutting of the exterior film 3 and, at the same time, guides the cutting direction at the beginning of opening. Is done. For this reason, when the knob 2a at one end formed by the notches 16, 16 is picked and pulled toward the other end, the initial advance of the opening strip 2 with respect to the exterior film 3 becomes easy, so that the exterior The film 3 can be cut smoothly. At this time, since the opening strip 2 is provided between the upper and lower ends of the exterior film 3, the exterior film 3 is cut vertically by pulling and removing the opening strip 2 to be divided into two. It will be.

A bag 2 is provided on the entire inner surface of the exterior film 3.
Form one. The bag portion 21 is formed between the films 3, 4, and 5 by bonding the left interior film 4 and the right interior film 5 to the exterior film 3. And
The bag portion 21 can cover the entire surface of the rice 20 on the inner surface side.

The left and right interior films 4 and 5 are each formed of a vertically long rectangular shape using a general-purpose film having thermal adhesiveness. Here, the width of each of the interior films 4 and 5 is slightly longer than the width of the vertical half of the exterior film 3.

The left interior film 4 has its left end aligned with the left end of the exterior film 3, its upper and lower edges aligned with the upper and lower edges of the exterior film 3, and its right end extends beyond the opening strip 2. In this way, the left interior film 4 covers the entire area on the inner surface side on the left half of the exterior film 3. Then, the left inner film 4 is heat-sealed with a predetermined width to the outer film 3 at the left end thereof and a portion extending from the left end of the upper and lower ends to the vicinity of the opening strip 2 and is sealed.

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

In this case, a portion on the right end side of the left interior film 4 and a portion on the left end side of the right interior film 5 are arranged in a non-adhered state at the center of the exterior film 3 in the short side direction. The polymerized portion is oriented vertically. The opening strip 2 is located at a portion corresponding to the overlapping portion of the left and right interior films 4 and 5. Therefore, the bag 21 is formed in cooperation with both the inner films 4 and 5 and the outer film 3, and a space partitioned from the outside is formed inside the bag 21.

Then, since the left interior film 4 and the right interior film 5 are not adhered to each other at their superposed portions, when the opening strip 2 is removed and the exterior film 3 is divided into two, the two interior films 4, 5 can be divided in the left-right direction. That is, when the exterior film 3 is vertically cut at the center in the width direction by removing the opening strip 2, the left half of the exterior film 3 and the left interior film 4 are integrated by the heat bonding portion 8. The right half portion of the exterior film 3 and the right interior film 5 can be divided into a single unit formed by a thermal bonding unit 9.

At the corners of the rice ball package 1, notches 18, 18,... Are provided. These notches 18, 18, ...
... are each formed of a parallel notch 18a and an inclined notch 18b, and are formed within the width of the thermal bonding portions 8 and 9 at both upper and lower corners of the package 1. At this time, the parallel notch 18a is formed in the up-down direction of the package 1, that is, in parallel with the opening strip 2, so as to face the opening direction.
The inclined notch portions 18b are connected to the parallel notch portions 18a in an oblique direction to reach the side end of the package 1, and are formed linearly.

In order to package the rice balls 20 using the rice ball packaging 1 configured as described above, first,
For example, the seaweed 17 which is a wrapping material is placed on the left and right
And is accommodated in the bag portion 21. 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 4 and 5.

Here, in order to store the laver 17 in the bag portion 21, the laver 17 is arranged on the inner surface side of the exterior film 3 in the process of manufacturing the package 1, and then the laver 17 is placed on the inner surface side of the laver 17 at the center. The left and right interior films 4 and 5 may be arranged in a superposed state, and a portion of the four sides of the peripheral edge portion except for the superposed portion may be thermally bonded. Nori 17 is rice 2
It is necessary to have a size that can cover the entire surface of the bag portion 0, and here, a rectangular shape is used so as to match the shape of the space in the bag portion 21.

The rice 20 is covered at the lower end 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 placed on the left and right interior films 4,
5 and the lower left and right sides 12 and 13 of the package 1
Bend. First, the lower right part 13 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 12 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 20 is covered on the upper half of the package 1. In other words, the upper half of the package 1
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 10 and 11 of the package 1 are bent. First, the upper right part 11 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 with the outer surface of the lower right 13. Similarly, the upper left portion 10 of the package 1 is bent along the lower left slope of the rice 20 in the direction e in the figure, and the bent portion is overlapped with the outer surface of the lower left portion 12. At this time, as shown in FIG. 6, the package 1 is adhered and held between the upper right part 11 and the lower right part 13 and between the upper left part 10 and the lower left part 12 by heat bonding or the like, respectively. Is preferred.

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 10 and the upper right part 11 of the package 1, a paper seal 19 such as a label is stuck and fixed so as to straddle, so that the package 1 covers the rice 20. It is held in the state where it was. 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 3,
This is preferable because the fastening of the package 1 becomes more complete.

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 2 and dividing the exterior film 3 into two, 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 17 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 17 is stored in the bag portion 21, a notch 16 is formed as a knob 2a by the notches 16 at the upper end side of the package 1. The user holds the end of the opened strip 2 and pulls it along the surface of the rice 20 toward the knob 2a of the opened strip 2 located at the lower end of the package 1. Then
The exterior film 3 is cut along the opening strip 2 as the opening strip 2 advances, or a part of the exterior film 3 is removed integrally with the opening strip 2. As a result, the exterior film 3 is cut straight in the vertical direction at the central portion in the short side direction, and the package 1 is divided into a left half and a right half.

Thereafter, when the user pulls the right end portion of the right half portion of the exterior film 3 to the right with the right end thereof, the right interior film 5 and the right half portion of the exterior film 3 bonded by the thermal bonding portion 9 are removed together. It is. At this time, since the right interior film 5 is located between the rice 20 and the laver 17, the right interior film 5 slides on the inner surface with the surface of the rice 20 and also slides on the outer surface with the laver 17 on the right side. And is removed to the outside through the gap of the laver 17. Therefore, as shown in FIG. 7, the right half of the rice 20 is exposed while being covered with the laver 17.

Next, the seaweed 17 is pressed against the right half of the rice 20 and is held by hand. On the other hand, in the same manner as described above, the left side of the left half of the exterior film 3 is pulled to the left side. The left interior film 4 and the left half portion of the exterior film 3 bonded by the bonding portion 8 are removed together. At this time, since the left interior film 4 is located between the rice 20 and the laver 17, the left interior film 4 slides on the inner surface with the surface of the rice 20 and on the left side while sliding on the outer surface with the laver 17. And is removed to the outside through the gap of the laver 17. For this reason, the left half of the rice 20 is also exposed while being covered with the laver 17.

As a result, rice 20 can be obtained in a state where rice 20 is entirely covered with laver 17, whereby rice balls are completed and can be easily eaten. In the above case, the right half of the package 1 is removed first, but it is desirable to remove the package 1 from the left half in the first embodiment shown. That is, the package 1 is packaged in a state in which the right end of the left interior film 4 is not in contact with the rice 20.
By pulling the left half of the first, the friction between the left interior film 4 and the rice 20 can be prevented.

In the above case, the rice 20 is wrapped in a state in which the seaweed 17 is stored in the bag portion 21, so that the seaweed 17 does not come into contact with the rice 20 until immediately before eating the rice ball. For this reason, the seaweed 17 is not moistened by the moisture of the rice 20 when in the packaged state, so that the flavor of the seaweed 17 is not impaired. Therefore,
You can always eat delicious onigiri when you open it.

Further, in a state where the left and right interior films 4 and 5 are superimposed on each other in a non-adhered state, a peripheral portion thereof is adhered to the exterior film 3 and the exterior film 3 is cut into two parts so as to pass through the non-adhered portion. The provision of the opening strip 2 allows the left interior film 4 and the right interior film 5 to be divided when each half of the exterior film 3 is separated. For this reason, the exterior film 3 separated by removing the opening strip 2 can simultaneously separate the interior films 4 and 5 by pulling each half. Moreover, by removing the inner and outer films 3, 4, and 5, the rice ball is completed with the rice 20 covered with the laver 17 at the same time. Therefore,
Since the seaweed 17 and the rice 20 can be easily combined at the same time as the opening, the rice ball can be easily eaten without any trouble.

In the above-mentioned rice ball wrapper 1, the opening strip 2 can be easily removed at the time of opening, and
You can be sure.

That is, the notches 1 are provided at both corners of the package 1.
By providing 8, 18,..., As shown in FIG. 6, the overlapping portion G of the upper left portion 10 and the upper right portion 11 at the center in the short side direction where the opening strip 2 is located is reduced. Is available. That is, at both corners of the package 1,
By providing the substantially trapezoidal cutouts 18, 18,... Composed of the parallel cutouts 18a and the inclined cutouts 18b, the corners of the upper left part 10 and the upper right part 11 are eliminated. , The corners of the package 1 do not overlap each other. For this reason, the opening strip 2
However, there is almost no obstacle other than the seal 19 on the line for cutting the exterior film 3. Therefore, at the time of opening, the overlapping portion G is opened
, The cutting of the exterior film 3 by the opening strip 2 becomes easy, and the division of the package 1 can be ensured.

In the above-mentioned rice ball wrapper 1, the wrapping direction can be increased.

That is, notches 18 are provided at both upper and lower corners of the package 1, and the opening strip 2 is provided.
Since the knobs 2a are provided at the upper and lower ends of the package 1, the lower left and right lower parts 12 and 13 can be wrapped on the outer surfaces of the upper left and right upper parts 10 and 11 of the package 1, respectively. That is, in the case of the above embodiment, since the left and right upper portions 10 and 11 are overlapped on the outer surface sides of the left and right lower portions 12 and 13 of the package 1, the notches 18 provided at both upper corners of the upper end of the package 1 are provided. , 18 greatly reduce the overlapping portion G of the upper right and left 10,11. Similarly, even when the left and right lower parts 12 and 13 are wrapped so as to overlap the outer surfaces of the left and right upper parts 10 and 11 of the package 1, the notches 18 provided at both corners at the lower end of the package 1,
18 significantly reduces the overlapping portion G of the lower left and right 12,13.

Therefore, even if the above-mentioned package 1 is brought into contact with and covered with rice 20 from either the upper or lower half,
Since the overlapping portion G of the package 1 on the line of the opening strip 2 can be reduced, it is not necessary to determine the vertical direction of the package 1 during the packaging operation.

Further, the notch 1 is formed within the width of the heat bonding portions 8 and 9.
By forming 8, 18,..., The bag portion 21 is prevented from communicating with the outside. For this reason, since the hermeticity inside the bag part 21 is ensured, the seaweed 17 does not become wet with the moisture contained in the outside air, and the seaweed 1
7 can be maintained.

Next, a second embodiment will be described with reference to FIGS. FIG. 8 is a schematic rear view showing the interior side of the onigiri package, and FIG. 9 is a sectional view taken along line BB in FIG. That is, the rice ball wrapper 31 shown in FIGS. 8 and 9 is obtained by deforming one of the left and right inner films 4 and 5 in the first embodiment. That is, the folded portion 37 is formed on the right interior film 35 used for the illustrated package 31. Since other configurations are the same as those of the first embodiment, detailed description is omitted by attaching the same reference numerals.

In FIGS. 8 and 9, the right interior film 35 has a vertically long rectangular shape larger in width than the right interior film 5 in the first embodiment. The right interior film 35 covers the inner surface of the right half of the exterior film 3 with the right end thereof aligned with the right end of the exterior film 3 and the upper and lower ends thereof aligned with the upper and lower ends of the exterior film 3, respectively. Placed. At this time, the right interior film 35
Is disposed in a state of non-adhesively overlapping a portion on the right side of the inner surface of the left interior film 4.

In the right interior film 35, a portion exceeding the right end of the left interior film 4 is folded inward to form a folded portion 37. In this case, the fold is made to pass over the opening strip 2. The right interior film 35 is heat-sealed with a predetermined width to the exterior film 3 at the right end thereof and a part extending from the right end of the upper and lower ends to the vicinity of the opening strip 2 and is sealed.

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 37 is formed at the left end of the right interior film 35, the exterior film 3 is formed.
When the package body 31 on the right half side is pulled after the cutting, the right interior film 35 is moved rightward so as to be peeled off from the rice 20.

In other words, when the folded portion is not formed as in the first embodiment, the right interior film 35 is
If the right half of the package 31 is pulled to the right side, it may be rubbed against the surface of the rice 20 and moved to the side, so that a tensile force acts on the rubbed portion to break the shape of the rice 20. There is. According to the second embodiment, when the right half package 31 is pulled rightward, the right interior film 35 is pulled.
Moves on the surface of the rice 20 while peeling in the direction of 180 ° to the right from the left end (folded portion) of the folded portion 37. For this reason, since the pulling force is not applied to the rice 20 when the package 31 is removed, the rice 20 can be eaten in a regular state without being deformed.

In the above case, the left interior film 4 is
The right end is located between the right interior film 35 and the exterior film 3 and is not in contact with the rice 20. Therefore, at the time of opening, if the package 31 is divided and then removed from the left half first, it is effective because the left interior film 4 does not rub against the rice 20.

Next, a third embodiment will be described with reference to FIGS. FIG. 10 is a schematic rear view showing the interior side of the onigiri package, and FIG.
It is a C line sectional view. That is, the packaged rice ball 51 shown in FIGS. 10 and 11 is a modification of the left interior film 4 and the right interior film 5 in the first embodiment. That is, folded portions 56 and 57 are formed in the left interior film 54 and the right interior film 55 used for the illustrated package 51. Since other configurations are the same as those of the first embodiment, detailed description is omitted by attaching the same reference numerals.

In FIG. 10 and FIG. 11, the left interior film 54 is the left interior film 4 in the first embodiment.
It is in the shape of a vertically long rectangle wider than it is. The left interior film 54 covers the inner surface of the left half of the exterior film 3 with its left end aligned with the left end of the exterior film 3 and its upper and lower ends aligned with the upper and lower ends of the exterior film 3. Placed. Then, the left interior film 54
The left end and the part extending from the left end of the upper and lower ends to the vicinity of the opening strip 2 are thermally bonded to the exterior film 3 with a predetermined width to be sealed.

The right interior film 55 has a vertically long rectangular shape wider than the right interior film 5 in the first embodiment. The right interior film 55 covers the inner surface of the right half of the exterior film 3 with its right end aligned with the right end of the exterior film 3 and its upper and lower ends aligned with the upper and lower ends of the exterior film 3, respectively. Placed. The right interior film 55 has its right end and a portion extending from the right end of the upper and lower ends to the vicinity of the opening strip 2 thermally sealed with a predetermined width to the exterior film 3 to be sealed.

At this time, the left end of the right interior film 55 is disposed so as to be non-adhesively overlapped with the inner right end portion of the left interior film 54. Then, in the left interior film 54, a portion beyond the left end of the right interior film 55 is folded inward to form a folded portion 56.
In the right interior film 55, a portion beyond the fold of the left interior film 54 is folded inward to form a folded portion 57. In this case, the respective folds of the left and right interior films 54 and 55 are set so as to pass over the opening strip 2, and the left interior film 54 and the right interior film 55 are not centered in the short side direction center of the exterior film 3. It is arranged so as to be overlapped by bonding. Therefore, the left and right interior films 54 and 55 are thermally bonded to the exterior film 3 at the peripheral edges except for the overlapping portions.

Then, the package 5 configured as described above
In the first embodiment, in addition to the operation described in the first embodiment,
The package body 51 can be removed without damaging the rice 20.

That is, since the folded portion 57 is formed at the left end of the right interior film 55, the exterior film 3
When the package body 51 on the right half part is pulled after the separation, the right interior film 55 is moved rightward so as to be peeled off from the rice 20.

That is, according to the third embodiment, when the right half package 31 is pulled rightward, the right interior film 5
5 moves on the surface of the rice 20 while peeling in the direction of 180 ° to the right from the left end (folded portion) of the folded portion 57. For this reason, the pulling force is not applied to the rice 20 when the package 51 is removed, so that the rice 20 can be eaten in a regular state without being deformed.

According to the third embodiment, the package 5
Even if the rice 20 is removed from either half after the division, the shape of the rice 20 does not collapse.

That is, since the folded portions 56 and 57 are formed on the left interior film 54 and the right interior film 55, even if the left or right half of the package 51 is pulled first, each interior film 54 and 55 is , So as to be peeled off from the rice 20 and move to the side.

Generally, in the case shown in the figure, the folded portion 56 of the left interior film 54 is
It is desirable that the package 51 be removed from the left half since it is located on the outer surface side with respect to the folded portion 57. That is,
The package 51 is such that the right end of the left interior film 54 is the rice 20.
Since it is packaged in a state where it is not in contact with, by pulling the left half of the package body 51 first from this state, it is possible to prevent friction from occurring between the left interior film 54 and the rice 20. it can.

Here, in the case of the one shown in the figure, the packaging is performed with the folded portion 57 of the right interior film 55 in contact with the rice 20.
Even if the right half of 1 is removed and the remaining left half is removed later, the right interior film 55 does not apply a pulling force to the rice 20.

First, if the right half of the package body 51 is first pulled to the right, the folded portion 57 of the right interior film 55 moves while being peeled off the rice 20 and is removed. No friction occurs between them. When the right half of the package 51 is removed in this way, the folded portion 56 of the left interior film 54 comes into contact with the rice 20 this time. Thereafter, when the left half of the package body 51 is pulled to the left, the left interior film 54 is moved and removed while the folded portion 56 is peeled off from the rice 20 as in the case of the right interior film 55. So,
No friction occurs with the rice 20. Therefore, when the package 51 is removed, even if the rice 20 is pulled from either the left or right half, the rice 20 is left and right inside the film 5.
The rice balls 20 are not rubbed with each other, so that rice balls can be completed without breaking the shape of the rice 20.

In the first to third embodiments, the outer film 3 and the left and right inner films 4, 5,
The materials of 35, 54 and 55 are not particularly limited. For example, it may be made of polypropylene or polyethylene, and a general-purpose film may be used. In particular, the left and right interior films 4, 5, 35, 5
As the materials 4 and 55, those made of polyethylene which are easy to separate from the rice 20 are preferable.
What is necessary is just a thing with a good separation from 0.

The shape of the exterior film 3 is the first
The present invention is not limited to those shown in the embodiments to the third embodiment, but may be any size and shape that can cover the rice 20. Furthermore, left and right interior film 4,
As for the shapes of 5, 35, 54 and 55, as long as the bag portion 21 is formed between the portion covering the rice 20 and the exterior film 3, the shape shown in the first to third embodiments described above. It is not limited to. That is, in the above-described first to third embodiments, the packages 1, 31, and 51 that wrap the triangular rice 20 are shown as an example, but the packages 1, 31, and 51 are used.
Can be deformed according to the shape of the rice 20. Therefore, it is possible to package not only the rice 20 having a triangular shape as shown in the figure, but also other shapes such as the rice 20 having a cylindrical shape.

Further, in the above-described first to third embodiments, the opening means is provided on the exterior film 3 with the opening strip 2.
Is shown, but the present invention is not limited to this. For example, a pair of perforations may be provided between the upper and lower ends of the exterior film 3 at predetermined intervals, and a strip or a band may be formed between the perforations. In particular, when the exterior film 3 is formed of a stretched film, the opening means does not provide the opening strip 2 and provides a pair of notches 16, 16 at at least one of the upper and lower ends of the exterior film 3. Or just For example, the exterior film 3 was formed of a uniaxially stretched film or a biaxially stretched film, or a laminate of a uniaxially stretched film and a non-oriented film or a laminate of a biaxially stretched film and a non-oriented film. In this case, even if the opening strip 2 is not provided, the outer film 3 is cut in the longitudinal direction at the width between the notches 16, 16 by simply pulling with the knob 2a formed between the notches 16, 16. , The ease of opening is maintained. When a stretched film is used as the exterior film 3 as described above, the opening means may be only the opening strip 2 without providing the notches 16 and 16.

[0070]

According to the present invention as described above, according to the present invention, in both corners of the upper and lower ends of the package, by providing the notch on, since the overlapping portion of the corner portion of the package in the packaging condition ends When the outer film is cut by the opening means at the time of opening, there is almost no obstacle to the cutting. In other words, according to the present invention , the package body can be easily and reliably opened by reducing the overlapping portion of the package body, so that the packaging film can be easily cut by the opening means.

Further, since the cutouts are provided at both the upper and lower corners of the package, even if the package is packaged from either upper or lower direction,
Since the overlapping portion of the package, which is an obstacle to the cutting by the opening means, can be reduced, there is a merit in the work surface at the time of packaging.

In addition, when the cutout is provided within the width of the adhesive portion, the sealing performance of the bag for accommodating the wrapped material such as laver can be ensured. For this reason, there is an effect that the wrapped material accommodated in the bag portion does not get wet with external moisture and can be eaten delicious at any time.
