【Example】

 An embodiment of the present invention shown in the drawings will be described below.

FIG. 1 and FIG. 2 show a first embodiment of a packaging material according to the present invention, in which the packaging material 1 has a square outer film 3 and two inner films. 4 and 4 are formed by polymerization.

That is, the outer film 3 is attached with the unsealing tape 2 from the central part of one end to the central part of the other end opposite to each other, and the unsealing tape 2 is attached to both sides of the unsealing tape 2. Notches 6 and 6 are provided, and the periphery is made of biaxially oriented polypropylene which is a polyolefin film coated with a low temperature heat-adhesive resin.

On the other hand, the two inner films 4 and 4 have a rectangular shape and are made of high density polyethylene, and the inner portions are bent outward to form the folded portions 7, 7. At the central portion of the outer film 3, the unsealing tape 2 overlaps in the same direction.

Therefore, as shown in FIG. 2, the inner portions of the inner films 4 and 4 are respectively formed with the folded-back portions 7 and 7 which are folded outward, and the folded-back portions 7 and 7 are formed. The caterpillars are superposed so as to overlap each other in the central portion of the outer film 3.

Further, a sheet-like food product such as seaweed stored inside is sealed with a seal 5 between the outer film 3 and the inner films 4 and 4 at four peripheral edges excluding the vicinity of the opening tape 2. 8 is positioned.

In the packaging material 1 configured as described above, first, as shown in FIG. 1, the opening tape in which the top of the triangular rice ball rice 20 is the side where the notches 6 are provided. 2 is oriented so that one end thereof is oriented and the bottom portion thereof is located at a substantially central portion in the longitudinal direction.

Next, as shown in FIG. 3, one half portion 10 of the packaging material 1 is folded so that both sides of the triangular rice ball rice 20 are covered with the half portions 9 and 10 of the packaging material 1. Fold both corners 11 and 11 of the half 10 to cover the slope of the triangular rice ball rice 20, and insert both corners 12 and 12 of the other half 9 together with the corners 11 and 11 in the direction of arrow B. Fold it in the same direction, and then fix it with labels 13 so that both corners 12 and 12 are not released (Fig. 4).

When eating the rice ball, the opening tape 2 is picked up while the rice ball is fixed with the label 13 and the rice ball is wound around the rice ball substantially once, and the notches 6, 6 are formed on both sides of one end of the opening tape 2. Since the outer film 3 can be easily torn along the notches 6 to divide the outer film 3 into two, the label 13 is also torn apart.

On the other hand, since the inner films 4 and 4 and the folded portions 7 and 7 are originally divided, it is not necessary to divide them again. When one of the two parts is pulled in the direction of the arrow in FIG. 4, the relationship between the triangular rice ball rice 20, the packaging material 1, and the seaweed that is the sheet-shaped food 8 is as shown in FIG. The inner film 4 is peeled off so that the folded-back portions 7 are sequentially flipped from the triangular rice ball rice 20 (see FIG. 6), whereby one of the easily divided portions is removed and sheet-like food such as seaweed is removed. 8 can be contacted with the triangular rice ball rice 20, and the other part can be similarly contacted.

Therefore, there is no possibility of the triangular rice ball rice 20 being rubbed by the folded-back portion 7 and being damaged when peeled off.

In the above embodiment, the outer film and the inner film have a square shape, but the shape is not limited to this and may have any shape.

Further, in the above-mentioned embodiment, the materials of the outer film and the inner film are the same, which is relatively easy to bond, but it is sufficient when the outer film and the inner film are different materials. In order to obtain good adhesive strength, first, apply an adhesive resin with good adhesiveness to the outer film, overlay it with an adhesive resin with good adhesiveness, and apply a so-called double coat. Sufficient adhesive strength can be obtained in this case. In this case, the adhesive resin having good adhesiveness to the outer film does not have to be a heat adhesive resin, and the adhesive resin having good adhesiveness to the inner film. Is a heat-adhesive resin.

A second embodiment of the packaging material according to the present invention is shown in FIGS. 7 and 8, and in this packaging material 21, one synthetic resin film is used.

This synthetic resin film is a biaxially stretched film, and an unsealing tape 22 is provided in the central portion in the width direction, and notches 26, 26 are provided on both sides of the unsealing tape 22. There is.

Then, both side portions in the width direction are folded back to the upper side through the bent portions 23, 23 to form the outer film 24 in the remaining central portion and the inner films 25 1, 25 in the folded portion. Then, the end portions of the both inner films 25, 25 are further folded back to the upper side through the bent portions to form the folded portions 27, 27. The folded portions 27, 27 are at the central portion of the outer film 24. Form to polymerize.

Further, as shown in FIG. 7, a seal 28 is formed between the outer film 24 and the inner films 25, 25 at the four peripheral edges except the vicinity of the unsealing tape 22, and the outer film 24 and the inner film are sealed. The sheet-like food 29 such as seaweed stored between the film 25 and the film 25 is positioned.

The seal 28 may be a spot seal or a full-face seal, and the packaging material 21 is formed by this.

Even the packaging material 21 configured as described above is covered with triangular rice ball rice in the same manner as in the above-mentioned embodiment, and when it is eaten, the unsealing tape 22 is similarly picked and the circuit material is wrapped around for about one round. Then, the packaging material 21 is divided and the triangular rice ball rice is wrapped with the sheet food 29 such as seaweed.

9 and 10 show a third embodiment of the packaging material according to the present invention.

In the example shown in this embodiment, the outer film 34 and the inner films 35, 35 having the folded portions 37, 37 are formed by using one synthetic resin film as in the second embodiment. It is formed by forming two cut lines 36, 36 in the central portion of the outer film 34, and attaching a wide opening tape 32 so as to cover the cut lines 36, 36.

Even in the case of such a configuration, the four peripheral edges of the outer film 34 and the inner films 35, 35 excluding the vicinity of the score lines 36, 36 are adhered to each other, and the sheet-like food is positioned inside. Then, the triangular rice ball rice is packaged in the same manner as in the above-mentioned respective embodiments, and the outer film is similarly torn when eating.

In each of the above embodiments, notches may be provided on both sides of the unsealing tape, or may not be provided.

[0036]

[Effect of the device]

 By being configured as described above, this invention has the following effects.

First, since the unsealing tape is provided on the outer film, the outer film can be easily torn by simply picking the unsealing tape and making a round of the rice ball.

Further, since the inner film is provided with a folded portion and the folded portion is brought into contact with the triangular rice ball rice, the inner film is folded when opened after tearing the outer film to divide the packaging material into two parts. The triangular rice ball is peeled off from the rice so that the parts are flipped, and it can be separated with a small force, so the triangular rice ball is not damaged.

Furthermore, since the opening tape is used for the outer film that tears when eaten, it is not breathable before tearing, and therefore the sheet-like food stored between the outer film and the inner film may become damp. There is no.
