Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a packaging material, and particularly to a packaging material suitable for use in wrapping glued rice balls.

[Conventional technology]

2. Description of the Related Art Conventionally, there has been known a rice ball wrapping body in which a rice ball is wrapped in a packaging material containing a plate paste, and when the rice ball is eaten, the packaging material is opened and the plate paste is wrapped around the rice ball. An example of a packaging material used for the packaging body is proposed in Japanese Utility Model Publication No. Sho 63-114969. Fig. 9, Fig. 1
Figure 0 shows the packaging material 1. This packaging material 1
Is a flat rectangular bag formed by an exterior film 3 having a tear tape 2 for opening at the center and an interior film 4 having a peripheral edge bonded to one surface thereof, and a flat bag is formed therein. Contains Nori 5 The interior film 4 is composed of two films arranged so as to overlap in the center of the bag so that it can be separated from the center to the left and right,
In addition, in order to improve the peeling of the rice ball, the tip of each film is folded back to form a peeling film 4a. Reference numeral 6 in the figure denotes a seal portion between the exterior film 3 and the interior film 4.

To wrap rice balls with this wrapping material 1, see Fig. 11, Fig.
As shown in Fig. 12, sandwich the rice ball 7 with the wrapping material 1 so that the tear tape 2 is almost in the center of the rice ball 7 with the interior film side inside, and further, the corners on both sides of the overlapping end of the wrapping material 1 The parts 1A and 1B are respectively folded on the front surface of the rice ball 7 as shown in FIG. At this time,
The cross section of FIG. 13 viewed in the direction of arrow AA is as shown in FIG. 14 (a), and the release film 4a is in contact with the rice ball 7.

In order to open the packaging material 1 in which the rice balls 7 are thus wrapped and wind the inner plate glue 5 around the rice balls 7, first, the tear tape 2 is pulled along the circumference of the rice balls 7 so that the exterior of the packaging material 1 is covered. The film 3 is separated into right and left at the center (see FIG. 14 (b)). Next, the lower end 1C of the packaging material 1 is pinched and pulled laterally. Then, as shown in FIG. 14 (c), the exterior film 3 and the interior film 4, and the peeling film 4a on the one end 1C side are peeled off from the rice ball 7 and the plate paste 5, and the plate paste 5 is exposed to expose the inside rice ball. Wrap around 7. Further, when one end 1D on the opposite side is pulled in the lateral direction, the remaining plate glue 5 is exposed and wound around the rice ball 7. In this way, the rice ball 7 can be rolled with a plate paste without directly touching it. Here, one end of the interior film 4 is folded back to form the release film 4a.
This is so that the film that is in direct contact with can be easily peeled off. That is, as shown in FIG. 14 (c), one end of the interior film 4 is folded back to release the release film 4a.
Then, when peeling it off, the peeling film
4a can be peeled off from the center of the rice ball, making it easier to peel than simply sliding it off.

[Problems to be solved by the device]

However, with such a conventional structure, the release film 4a is originally
Should be easily peeled from the rice ball 7, but in reality it does not easily peel off, a large force is required for peeling, and there is a problem that the rice ball may be broken during peeling.

The present invention has been made in view of such conventional problems, and an object of the present invention is to provide a packaging material capable of extremely easily peeling off a release film that comes into contact with a rice ball.

[Means for solving the problem]

The present inventors have examined the reason why it is difficult to remove the conventional release film, and as a result, as shown in FIG. 15, the release film 4a and the interior film 4 are bent along the rice ball 7, It was found that the movement of the release film 4a was restricted at the fold portion 8 and it was difficult to remove the release film 4a. Then, it has been found that peeling can be extremely facilitated by making a cut in the release film at the fold portion 8.

The present invention has been made on the basis of such knowledge, and is characterized in that a cut is formed along a portion of a release film, which is provided so as to come into contact with an object to be packaged such as a rice ball, to be folded at the time of packaging.

〔Example〕

 An embodiment of the present invention will be described below.

FIG. 1 is a schematic perspective view of a packaging material 11 according to an embodiment of the present invention, and FIG. 2 is a schematic sectional view thereof. The packaging material 11 is such that the plate glue 15 is housed in a rectangular bag having an exterior film 13 having a tear tape 12 for opening at the center and an interior film 14 capable of separating the center. This interior film 14
In order to make the center separable, two separate films are used from the beginning, and the leading ends of the two films are folded back to form a release film 14a located on the outer surface of the interior film 14. Each of the release films 14a has two cuts 16 formed substantially in the center thereof. The cut 16 is formed along a position that becomes a bending portion when the rice ball is wrapped with the packaging material 11.

The outer film 13 and the inner film 14 are bonded at their peripheral edges by a seal portion 17. The exterior film 13 and the interior film 14 do not necessarily have to be configured as separate films, and may be configured by folding one film.

The packaging material 11 having the above structure is also used as in the conventional case. That is, as in the conventional example shown in FIG. 9 to FIG.
It is used for packaging and is opened in the same way. Here, as shown in FIG. 3, the inner film 14 and the release film 14a of the packaging material 11 in which the rice ball 7 is wrapped can be folded along the bottom of the rice ball 7, and a cut 16 is formed in the bent portion. Has been formed. Therefore, the release film 14
The vertical part and the horizontal part are separated by the cut line 16 so that they do not interfere with each other. By this,
When the inner film 14 and the release film 14a are peeled from the rice ball 7 by pulling the end portion of the inner film 14 in the direction of the arrow X, the release film 14a is favorably turned over, and the whole can be easily peeled and removed.

In addition, in the above embodiment, two cuts 16 are formed on each release film 14a, and when the rice balls are wrapped, the cuts 16 are formed.
Is so that it can be bent. However, it may be difficult to accurately position the cut 16 at the corner of the rice ball during packaging. In order to avoid the difficulty, three or more cuts 16 may be formed at an appropriate pitch. With this configuration, when the rice ball is wrapped by the packaging material 11, even if the position of the rice ball deviates to some extent, any of the cuts will be at a position where the rice ball is bent to facilitate the packaging work.

The material of the outer film 13, the inner film 14 and the like used for the packaging material 11 is not particularly limited, but is usually
A resin single-layer film or a laminated film is used.
Since the interior film 14 needs to be peeled from the rice ball 10 and slide on the inner plate paste 15, it is preferable to use a film having good slipperiness. Further, since the exterior film 13 also needs to slide with respect to the internal plate glue at the time of opening, it is preferable to use a film having good slipperiness. Since the exterior film 13 is the surface that becomes the outer surface when the rice balls are packaged, it may be printed and is preferably a film having good printability. Further, if heat sealing is used to bond the exterior film 13 and the interior film 14, it is easy to manufacture, and therefore a material having heat sealing properties is preferable.
In consideration of these, as the material of each film, it is preferable that the interior film 14 is an OPP having heat sealability, the exterior film 13 is an OPP having heat sealability, or a laminated film of PE and PET.

In the above embodiment, the end portion of the interior film 14 is bent to form the release film 14a, but the present invention is not limited to this structure, and a film different from the interior film 14 may be used as the interior film outer surface. It is also possible to adhere it to a release film. An example in that case will be described below.

FIG. 4 is a schematic perspective view showing the packaging material 21 according to the embodiment, and FIG. 5 is a schematic sectional view thereof. In this packaging material 21, a plate glue 26 is housed in a rectangular bag composed of an exterior film 23 having a tear tape 22 for opening at the center and an interior film 25 whose periphery is sealed by a seal portion 24. are doing. The inner film 25 has an easy opening line such as perforations so that it can be easily torn at the center 27
Is formed. On the outer surface of the interior film 25, peeling films 29 joined by seal portions 28, 28 on both sides of the easy-open line 27 are provided. The peeling film 29 also has easily breakable lines 30 such as perforations so that the peeling film 29 can be easily torn at the portions sandwiched by the seal portions 28, 28. The easily breakable lines 27, 30 may be formed at positions overlapping with each other, but if they are offset from each other as shown in the illustrated embodiment, it is preferable because the effect of preventing moisture and foreign matter from entering from the outside is large. The easily breakable lines 27 and 30 may be ordinary perforations, but it is preferable to have long slits as shown in FIG. 4 because they are easy to tear.

In the release film 29, cuts 31 are formed on both sides of the seal portions 28, 28 at positions to be folded when the rice balls are wrapped with the packaging material 21. The number of breaks 31 is not limited to two as shown in the figure, and may be three or more.

The packaging material 21 of this embodiment is also used similarly to the packaging material 11 of FIG. That is, the peeling film 29 is attached to the rice ball so as to come into contact with the rice ball to form a packaging body having the form shown in FIG. At the time of opening, after cutting the exterior film 23 with the tear tape 22 at substantially the center, both ends of the packaging material 21 are pulled to the left and right. As a result, the easily breakable line 27 of the interior film 25 and the easily breakable line 30 of the peeling film 29 are broken, and then the peeling film 29 is peeled off from the center side. Also at this time, since the cut 31 exists in the bent portion of the release film 29, the release film 29 is peeled off smoothly.

In the above-mentioned embodiment, since the inner film 25 and the peeling film 29 that cover the plate glue 26 have no large cuts, foreign matter and moisture are less likely to enter from the outside, which is advantageous in that it is hygienic.

FIG. 6, FIG. 7, and FIG. 8 show an embodiment in which a part of the embodiment shown in FIG. 4 and FIG. 5 is modified. That is, in the embodiment shown in FIG. 6, the peeling film 29 is adhered to the interior film 25 at the central portion thereof, and the easily breakable line 34 is formed at the center of the adhesive portion 33 so as to be separated. In the embodiment shown in FIG. 7, two films 25a, 25a are arranged as an interior film at a predetermined interval, and a peeling film 29 having an easily breakable line 30 in the center is attached by a seal portion 28, 28 thereon. It was done. In the embodiment shown in FIG. 8, the interior film is composed of two films 25b and 25b,
Peeling films 29a and 29a are attached to them, respectively, and sealing parts 36 and 36
And the release film 29a adhered to the other interior film and the release film 29a adhered to the other interior film are overlapped. The embodiment shown in FIGS. 6 to 8 is also shown in FIGS.
Similar to the embodiment shown in the figure, the release film has a cut in the bent portion, and the same effect is obtained.

It is to be noted that the release film used in these examples is also preferably a film that easily peels from the rice ball and has good slipperiness, such as OPP, so that it can be easily peeled from the rice ball.

[Effect of device]

As described above, in the packaging material of the present invention, since a cut is formed along the part of the release film that comes into contact with the packaged object such as rice balls, which is folded at the time of packaging, the release film is removed from the packaged object. It has the effect that it can be peeled off very easily.
