[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wrapping film for rice balls, and more particularly, to directly wrapping rice balls (hereinafter referred to as straight rice balls) in which nori is wrapped directly on rice constituting rice balls, and rice balls not wrapped in nori. Suitable for
The present invention relates to an onigiri packaging film body that is extremely easy to package and open.

[0002]

2. Description of the Related Art In general, straight-wound rice balls sold at convenience stores and supermarkets are wrapped by an onigiri packaging film body 1 as in a first conventional example shown in FIGS. That is, the packaging film bag 2 for rice balls used for this packaging is formed in a bag shape by laminating the front and back two films 3 and 3 into a substantially U-shape and heat-bonding the bonding portion 7 by heat sealing or the like. . In the substantially U-shaped opening, an input port 9 for inputting the rice ball body O at the time of packaging is opened. Although the onigiri body O is illustrated as having a triangular shape, a generally circular one is generally sold.

[0003] Further, an opening means for opening is provided, which is formed by a protruding piece picking portion 4, a tape-shaped opening strip 5 and notches 6,6. The tab 4 is provided at the bottom end of the U-shape, and the opening strip 5 is arranged inside the bag from the end of the tab 4 to the inlet 9 along the center line of the bag. Is glued. The notches 6 and 6 are provided at the bottom edge with the opening strip 5 interposed therebetween.

[0004] Then, in order to package the rice ball body O in the above-mentioned rice ball packaging film bag body 2, first, the charging port 9 is set.
Insert the rice ball body O more. Next, as shown in Steps 1 to 6 in FIG. 23, the right side F1 is folded inward in Step 1 to fold the input port 9 portion of the onigiri packaging film bag body 2 and then the left side F2 in Step 2. Is folded inward, the front surface F3 is folded inward in step 3, and the rear surface F4 is folded forward in step 4. Further, in step 5, stop with adhesive tape T, and in step 6
By sticking a seal S such as a label, a folded portion 11 is formed and a predetermined packaging state is maintained, and FIG.
4 is completed.

In order to open the rice balls wrapped as described above, as shown in FIG. 25, first, the end of the opening strip 5 is pulled toward the other end and removed. Cut one side of the film vertically and left and right film 3
Split into L and 3R. Thereafter, the package body having one side of the rice ball cut open is pulled so as to push the films 3L, 3R to the left and right, thereby exposing the rice ball body O to be taken out.

[0006]

However, when packaging the rice ball body O using the rice ball packaging film body 1 constructed as described above, the packaging must be performed according to the complicated procedure as described above. Did not. From rice ball molding to laver winding is already automated, and it is 2,0 hours per hour.
Approximately 00 machines are widespread and processed at high speed. Recently, a fully automatic machine has been developed for the packaging process, but as described above, the packaging process is complicated, so the price is high, and it is hardly widespread yet. Therefore, at most manufacturing sites, the packaging operation is still performed manually, and about 4 to 5 packaging personnel, including replacement personnel, are attached to one rice ball forming machine. However, it is a difficult task for the machine partner to be able to keep his hands for a while, and also requires some skill, so securing human resources has always been a problem in the industry. There was also a problem that the labor cost had to be increased accordingly. Further, the cost of the adhesive tape as a stopper and the label to be applied from above to cover the adhesive tape was also a problem. According to some statistics, the number of rolled rice balls produced per day is 400
It is said that the number is more than 100,000, and it is a very serious problem in the industry as a whole that the labor and labor costs and the direct costs required for adhesive tapes, labels and the like increase. SUMMARY OF THE INVENTION In view of the above problems, it is a first object of the present invention to provide a packaging film and a packaging method which eliminates the folding portion 11 and which enables low-cost packaging of straight-wound rice balls and has high work efficiency.

Next, in order to open the wrapping film 1 for onigiri wrapped as described above, the film is cut and opened by the opening strip 5, but the film is folded as described with reference to FIG. Films F1 to F4 of the loading slot 9
(Folded portion 11) hinders, and only a part of one side of rice ball main body O can be exposed. For this reason, the onigiri body O is pulled out by pushing the film 3L, 3R to the right and left with the hand, and the onigiri body O is taken out. However, the onigiri body O and the film 3 are sticky due to the stickiness of the rice, and there is a problem that the onigiri body O is cracked or broken. In addition, the folded part was cluttered and the design was not good, and the opening was slow. SUMMARY OF THE INVENTION In view of the above problems, the present invention provides a packaging film and a packaging method for a straight-wound rice ball that allows both sides of the rice ball body O to be exposed at the time of opening and that can be easily and reliably opened and has a clean design. This is a second problem.

In the second conventional example shown in FIGS. 26 and 27, the opening strip 5 runs in the horizontal direction and cuts off the film portion covering the upper part of the rice ball main body O. Since the opening is narrow for separation, the rice ball main body O cannot be taken out as it is, and the first and second problems exactly the same as the first conventional example exist.

In the third conventional example shown in FIGS. 28 and 29, an opening strip 5 having a knob 10 is started from the side of the rice ball 1, and the opening is performed by pulling the knob 10 provided on the side. It is supposed to do. A cut line 12 is formed in the film 3 so that the initial stage of opening can be started smoothly. The onigiri packaging film body 1 is also hindered by the folded portion of the film 11 minutes, so that the onigiri body O cannot be taken out as it is, and the first and second problems are the same as in the first conventional example. Exists.

[0010] In addition, although not described in detail, several types of straight-wrapped rice ball wrapping film bodies that differ depending on the shop are currently used. In each case, the inlet 9 is folded and sealed, and there are first and second problems which are exactly the same as those of the first conventional example described above. In other words, in other words, all of the currently used packaging film bodies for straight-wound rice balls have the same problem, and solving this problem can have enormous economic effects for the entire industry.

[0011]

[0018]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 to FIG. 4 are explanatory diagrams of the first embodiment of the present invention. FIG. 1 is a schematic perspective view of an onigiri packaging film body 1 in a state where an onigiri body O is packaged, FIG. 2 is a front view, and FIG. 3 is AA.
FIG. 4 is a schematic cross-sectional view taken along a line, and FIG.

That is, the packaging film body 1 for onigiri of FIGS. 1 to 4 comprises a bag-shaped film 3 for accommodating the onigiri body O, and notches 6, 6 used at the time of opening.
Are formed from the tab picking portions 4 and 4 and the opening strip 5.

The film 3 is made of a general-purpose film having thermal adhesiveness. The rice ball body O is sandwiched from both sides, and the rice ball body O is thermally bonded to the peripheral portion of the rice ball body O to form the film 3 in a bag shape. However, the packaging film for rice ball 1
Are not thermally bonded, and the films 3 on both sides are continuously connected at the bottom 8. This is so that the cutting of the film 3 by the unsealing strip 5 proceeds smoothly on both the front and back surfaces of the rice ball body O at the time of opening.
It is configured in this way.

A method of packaging the rice ball body O by bonding the peripheral portion of the rice ball body O and forming the film 3 in a bag shape will be described later in detail in an embodiment of a packaging method. The method is not limited to thermal bonding, but may be bonding using a hot-melt adhesive or another adhesive, or taping with an adhesive tape or the like, and the bonding method is not particularly limited.

The onigiri packaging film 1 is provided with an opening means, and the opening strip 5 and the protruding portion 4,
4 are formed. The protruding knobs 4, 4 are located on the peripheral edge of the bottom 8 on the opposite side. Opening strips 5 are protruding tabs 4,4.
Starting from the end and passing through the bottom 8, the tabs 4, 4 on the rear surface
And is bonded to the inner surface side of the film 3 so as to reach. At this time, the opening strip 5 having a certain strength that is not easily cut is used.

The notches 6, 6 are formed as a pair of cuts on the protruding knobs 4, 4 with the opening strip 5 sandwiched therebetween. The notches 6, 6 may be formed on only one of the protruding knobs 4, 4. The notches 6, 6 serve as a trigger for cutting the film 3 at the time of opening, and at the same time, guide the cutting direction at the initial stage of opening. For this reason, when the end portion of the opening strip 5 sandwiched between the notches 6, 6 is pulled toward the other end, the initial advance with respect to the film 3 is facilitated.
The film 3 can be cut smoothly. In addition, the shape of the protruding knobs 4, 4 may be such that the front and rear two protruding knobs 4, 4 have different heights, or the upper end is cut into a V-shape instead of a single character. Although there are various formats for making it easy to pick 4, any of the formats may be selected. In addition, the bonding portion 7 between P1 and P2 may be heat-sealed with an adhesive pattern that can adjust the bonding force slightly rather than heat-sealing the entire surface so that the bonding portion 7 can be easily peeled at the time of opening. desirable.

At the time of opening, when the opening strip 5 is grasped with the hand HR and pulled and removed with the protruding knobs 4, 4, the opening strip 5 makes one round from the front to the back of the rice ball body O, and the rice ball The packaging film body for use 1 is cut vertically and completely divided into two pieces. In the conventional onigiri packaging film body 1, the folded portion 1 of the input port 9 is opened when opened.
1 prevents the opening strip 5 from proceeding, and the rice ball body O
It was not possible for the cutting line to make one round from the front to the back.

Since the configuration is as described above,
In the packaging film body 1 for onigiri of the present invention, the folding of the film 3 for sealing the inlet 9 of the onigiri body O at the time of packaging, which is the biggest problem in the prior art, is no longer necessary. This eliminates the need for stickers with adhesive tapes and labels, greatly reducing labor, labor costs and costs. . Also, since the folded portion 11 of the film 3 was completely eliminated, the design became beautiful.

Further, when the rice ball body O is taken out at the time of opening, the folded portion 1 of the film 3 which has been hindered from being opened.
Since 1 disappeared, the film 3 came to be completely separated into two. For this reason, it became possible to easily open the rice balls without breaking the rice balls or breaking the shape. Further, as shown in FIG.
If you try to eat the rice ball with your hand HL from one side 3L of the film 3 remaining after taking the rice, you can always eat the rice ball without touching the rice ball directly and without worrying about the dirt of the hand Can now be eaten. Conventionally, when taking out the rice ball body O,
The folding section 11 was messed up and hardly reached a comfortable state in which it could be stably grasped by hand.

Now, another embodiment of the present invention will be described below. In describing the other embodiments, only the differences between the configurations and operations of the other embodiments will be described.
The same components as described above are denoted by the same reference numerals, and redundant description will be omitted.

A second embodiment of the present invention shown in FIG. 5 will be described. The main difference between the first embodiment and the second embodiment is that the opening means is changed to the opening means using the stretchable film 3 which can be directionally torn from the opening strip 5. is there. That is, the packaging film body 1 for onigiri is composed of the stretchable film 3. In this way, the opening can be performed by pulling the tabs 4 and 4 without disposing the opening strip 5. With this configuration, the same operation and effect as those of the first embodiment can be obtained.

A third embodiment of the present invention shown in FIGS. 6 and 7 will be described. FIG. 6 is a front view, and FIG.
Is a sectional view taken along the line BB '. The main difference between the first embodiment and the third embodiment is that the lugs 4 and 4 at the beginning of the pulling of the opening strip 5 used in the opening means are replaced with the rice ball body O.
This is a point changed to the knob portion 10 which is arranged slightly inside from the peripheral portion. The knob 10 is adhered to the film 3 in the lower half thereof, and a cut line 12 is provided in the adhered portion of the film 3. The incision line 12 is provided to start tearing of the film 3 when pulling the knob 10 at the beginning of opening and to facilitate opening. With this configuration, the same operation and effect as those of the first embodiment can be obtained. Further, similarly to the second embodiment, the opening strip 5 used in the opening means may be replaced with a stretchable film 3 which can be torn in a directional manner, and the same operation and effect can be obtained.

The fourth embodiment of the present invention shown in FIGS.
An embodiment will be described. FIG. 8 is a schematic perspective view, and FIG. 9 is a sectional view taken along line CC ′. The main difference between the third embodiment and the fourth embodiment is a difference in the sealing method when the packaging film 1 for onigiri is formed using a film formed in a bag shape in advance. As a means for inserting the rice ball body O and sealing the inlet 9,
The sealing was performed by squeezing and squeezing the inlet 9 using a flexible cord 13 such as an adhesive tape, a string, a rubber band, or a wire instead of bonding. With this configuration, the same operation and effect as those of the first embodiment can be obtained.

A fifth embodiment of the present invention shown in FIGS. 10 to 12 will be described. FIG. 10 is a front view, FIG. 11 is a cross-sectional view taken along the line DD ′, and FIG. 12 is a perspective view showing an outline at the time of opening. First Embodiment and Fifth Embodiment
The main difference from this embodiment is the opening means. At the time of opening, the front and rear protrusions 4F and 4B of the front and rear tabs are pulled so as to be peeled in the front and rear direction (the directions of arrows of MF and MB). The opening progresses. Onigiri body O is gradually exposed from the top. The degree of exposure of the onigiri body O can be adjusted in accordance with the degree of progress of eating the onigiri body O, and during that time, the unopened onigiri packaging film body 1 can be opened.
You can eat by holding the lower part by hand. This makes it possible to eat the rice ball in a sanitary manner without touching the rice ball directly and without worrying about stains on the hand. In addition, the adhesive force of the adhesive portion 7 at the peripheral portion is determined by the film 3
By applying a force weaker than the tensile stress of the adhesive, the adhesive is adhered with such an adhesive strength that the adhesive can be easily peeled or peeled off. In addition, the film 3 on the front and back surfaces does not need to be continuous at the bottom portion 8 of the rice ball wrapping film body 1, and in this embodiment, the bottom portion 8 is adhered similarly to the other peripheral portions and adheres to the adhesive portion 7.
Is composed. Of course, the films 3 on the front and back surfaces may be continuously connected. With this configuration, the same operation and effect as those of the first embodiment can be obtained.

The sixth embodiment of the present invention shown in FIG. 13 will be described. The main difference between the first embodiment and the sixth embodiment is that the bottom portion 8 of the wrapping film 1 for a rice ball formed in a bag shape is bonded by bonding in the same manner as the other peripheral portion of the rice ball main body O. It is formed. With such a configuration, the opening means is interrupted at the time of opening, so that only one side of the rice ball main body O can cut the film 3, and the ease of opening is lost.
However, the advantage that there is no need to form the folded portion 11 at the time of sealing, which is a great feature of the present invention, is still secured. Therefore, as already described in the first embodiment, the manufacturing advantage is very large, and such a configuration may be adopted.

A description will be given of a seventh embodiment of the present invention shown in FIGS. The seventh embodiment is an example of an onigiri packaging film bag 2 that constitutes the onigiri packaging film 1 of the first embodiment,
The packaging method. FIG. 14 is a plan view of the packaging film bag 2 for onigiri, and FIG. 15 is a sectional view taken along line EE ′ of FIG. FIG. 16 is a schematic perspective view in which the charging port 9 is sealed, and FIG. 17 is a plan view showing unnecessary portions C1 and C2.

That is, the packaging film bag 2 for onigiri
Is composed of a film 3 forming the front and back surfaces of the bag, an opening strip 5 and notches 6, 6 used at the time of opening. The film 3 is a general-purpose film having thermal adhesiveness.

The film 3 cut into a substantially U-shape that forms the front and back surfaces has both ends sandwiching the bottom portion 8 by heat bonding to form a bonding portion 7. The bottom 8 is not adhered, and the films 3 on both sides are continuously connected at the bottom 8. This is so configured that the opening of the film 3 by the opening strip 5 can be smoothly and continuously progressed on both the front and back surfaces of the rice ball main body O at the time of opening. The upper end of the film 3 is opened without being adhered, and serves as an input port 9 for inputting the rice ball main body O. The film 3 as a whole constitutes a substantially U-shaped bag.

The method of bonding the film 3 is not limited to thermal bonding, but may be bonding using a hot-melt adhesive or another adhesive.
Alternatively, taping may be performed with an adhesive tape or the like, and the bonding method is not particularly limited.

The packaging film bag 2 for rice balls is provided with opening means, and the opening strip 5 and the notches 6, 6 are provided.
And formed. The opening strip 5 starts at the end of the input port 9 on the surface of the film 3, runs substantially vertically along the center line of the film 3, and passes through the bottom 8 to the end of the input port 9 on the back side of the film 3. Placed and glued. An opening strip 5 having a certain strength that is not easily cut at the time of opening is used.

The notches 6, 6 are formed as a pair of cuts at the end of the charging port 9 with the opening strip 5 being sandwiched therebetween.
The notches 6, 6 may be formed on only one of the front and rear surfaces of the film 3. Notch 6,
6 is an opportunity to cut the film 3 at the time of opening, and at the same time, the cutting direction at the initial opening is guided. Therefore, notch 6,
By pulling the end of the opening strip 5 sandwiched between 6 toward the other end, the initial advance to the film 3 is facilitated, so that the film 3 can be cut smoothly.

At the time of opening, the end of the opening strip 5 is grasped with a finger and pulled and removed.
One round from the front surface to the rear surface, the packaging film bag 2 for onigiri is cut vertically and completely divided into two pieces. In the conventional packaging film bag 2 for onigiri, the folded portion 11 of the insertion port 9 hinders the advancement of the opening strip 5 when opening, and the cutting line makes one round from the front surface to the rear surface of the rice ball main body O. That was impossible. As shown in FIG. 21 to FIG. 29, when the rice ball body O is wrapped, the input port becomes a 9-folded portion 11 as described above with reference to FIGS. Prong picking part 4, 4 that triggers start
Was provided on the bottom 8. On the other hand, in the wrapping film bag 2 for onigiri of the present invention, the lugs 4 and 4 can be formed at the end of the input port 9, so that the onigiri body O can make one round and can be completely separated.

Next, the packaging film bag for rice balls 2
A packaging method for accommodating the rice ball body O inside and forming the packaging film 1 for rice balls will be described with reference to FIGS. First, the input port 9 of the rice ball body O is opened, and the rice ball body O is loaded into the rice ball packaging film bag 2. Then, the rice ball O is placed on a guide G for positioning the rice ball main body O, and the rice ball packaging film bag 2 is fixed to a predetermined position by pressing against the wall surface of the guide. At this time, the orientation of the onigiri packaging film bag 2 is adjusted so that the charging port 9 is located just below the heater bar B1. Thereafter, the heater 9 is pressed downward (in the direction indicated by arrow M1) with a heater bar B1 having a curved shape along the periphery of the rice ball body O, which has been heated to an appropriate temperature, and the inlet 9 is fused and sealed. .

At the same time as welding with the heater bar B1, the protruding knob portions 4, 4 are also formed. Outside the pair of notches 6, 6 at the upper end of the input port 9, the bonding portions 7, which are both end portions of the protruding knob portions 4, 4, are formed on the knob forming portion Y 1 of the heater bar B 1.
Pressed and fused by Y2 to form. At the same time, the outside of the fusion sealing line, which is an unnecessary part of the film 3, is cut by fusing and removed as removal parts C1 and C2.

The shape of the lugs 4 and 4 may be different from each other, or the upper lugs may be cut into a V-shape instead of a single character. There are various forms for making the knobs 4 and 4 easy to pick, and any of the forms may be selected. The shape of the upper end of the inlet 9 is selected according to the format. In addition, the bonding portion 7 between P1 and P2 may be heat-sealed with an adhesive pattern that can adjust the bonding force slightly rather than heat-sealing the entire surface so that the bonding portion 7 can be easily peeled at the time of opening. desirable. As described above, at the same time as the sealing, the protruding pieces 4 and 4 are also formed, and the rice ball packaging film body 1 in which the rice ball main body O is accommodated inside is completed.

Although the method of sealing and packaging using the wrapping film bag 2 for rice balls provided with the picking portions 4 and 4 at the input port 9 has been described above, this method is applied to a bag-like film body. When packaging O, it can be applied to all,
The present invention is not limited to the packaging of a specific bag-like film body. For example, the same can be applied to the second and third conventional examples shown in FIGS. 27 and 29 given in the prior art examples. In this case, the knob forming portions Y1 and Y2 of the heater bar B1 are not required.

Since the configuration is as described above,
The film 3 which was used to seal the input port 9 of the rice ball body O at the time of packaging, which was the biggest problem in the prior art.
The need for the folding process has been eliminated. Along with this,
The need for stickers with adhesive tapes and labels has been eliminated, significantly reducing labor, labor and costs. . Also, since the folded portion 11 of the film 3 was completely eliminated, the design became beautiful. In addition, open the film 3
Easily and completely separated into two, and the separated film 3
Can now provide hygienic rice balls that can be grabbed by hand and eaten.

An eighth embodiment of the present invention will be described with reference to FIG. The eighth embodiment is similar to the seventh embodiment.
The opening means of the packaging film bag 2 for onigiri of the embodiment is changed to the opening means using the stretchable film 3 which can be directionally torn from the opening strip 5. That is, the packaging film bag 2 for onigiri is constituted by the stretchable film 3. In this way, the same operation and effect as in the seventh embodiment can be obtained without disposing the opening strip 5.

A ninth embodiment shown in FIGS. 19 and 20 will be described. The ninth embodiment is a method for packaging a rice ball body O using a film. 19 and 20 are schematic perspective views showing the steps of packaging. The main difference from the example of the packaging method of the seventh embodiment is that the packaging film bag 2 for rice balls is not used,
That is, the packaging film body 1 for onigiri is formed only by one step of heat sealing from the film. First, after the rice ball O is placed on the film 3 having a square shape as shown in FIG. 19, the film 3 is folded and the rice ball O is folded in a U-shape. As a result, a film surface sandwiching the front and back of the rice ball body O is formed. The front and back films 3 are connected at the folded portion of the film 3, that is, the portion corresponding to the U-shaped bottom, and the other front and back films 3 are still open. Next, as shown in FIG. 20, the rice ball body O sandwiched between the films 3
Is set on the pedestal D. This pedestal D is the rice ball O
The surface of the rice ball O can be positioned in a predetermined position and direction.
Next, a heater bar B2 having a shape along the periphery of the rice ball body O except for the bottom portion 8 is moved downward (in the direction of the arrow M2).
To fuse. At the same time, the unnecessary portion of the film 3 is cut off by fusing to complete the rice ball packaging film body 1 in a state where the rice ball body O is housed inside.

This packaging method does not require the onigiri packaging film bag body 2 formed in a bag shape in advance as compared with the packaging example of the seventh embodiment, and is performed by one-time fusion with a heater bar. By the process, the rice ball body O can be sealed together with the formation of the bag shape, and the efficiency is high. Even with this configuration, the seventh
The same operation and effect as those of the embodiment can be obtained.

In each of the embodiments described above, the present invention has been described with respect to a triangular rice ball. Needless to say, the present invention is applicable to other shapes of rice balls, and the present invention is not limited to the shape of the rice balls. Also, when wrapping triangular rice balls, you can freely decide the direction of the rice balls,
The direction is not limited.

[0049]

As described above, according to the present invention, since the rice ball body is sealed and packaged by bonding, the folded portion required for the prior art can be eliminated, and the following effects can be obtained. Can be (A) Since the folding work at the time of packaging, which has been the biggest problem in the past, is no longer necessary, the number of packaging personnel is reduced to 1/2 to 1/3, so that the cost can be greatly reduced and the securing of personnel becomes easy. (A) A sealing material such as an adhesive tape or a label for sealing the folded portion 11 becomes unnecessary, resulting in a large cost reduction. (Even if the number of tapes and seals used per onigiri is very small, it would be a huge amount if 40 million pieces are produced per day.) (C) When the onigiri is opened, the film is completely and easily removed.
Since the rice ball body is exposed from the film as in the prior art, the rice ball body is not broken or broken, so that it is easy to eat. (D) The onigiri can be eaten by holding the rice ball itself with one of the two separated films, so that even dirty hands can eat the onigiri safely. Product value is improved in line with recent consumer hygiene and cleanliness preferences. (E) The unsightly folds are eliminated and the design is clean. Also, the printing design of the film became easier.
