Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a packaging material, and more particularly to a packaging material suitable for packaging rice balls and the like.

[Prior art and its problems]

Generally, regarding packaging materials sold at convenience stores and the like, various packaging forms are available on the market, and the packaging materials can be roughly classified into quadrangles, triangles, and variations thereof.

Among them, as a conventional packaging material whose shape belongs to a quadrangle, there is a packaging material for packaging contained items such as rice balls as shown in FIG.

The packaging material 31 for rice balls is divided into two pieces in the longitudinal direction of a rectangular outer film 33 to which an unsealing tape 32 is attached from the central portion of one end to the central portion of the other end opposite to the outer film 33. Two square inner films 34, 34 each having a width slightly larger than the ones are positioned so that the central portions thereof overlap each other, and the four sides excluding the portion where the opening tape 32 is adhered are heat-melted. The outer film 33 and the inner films 34, 34 are integrated with each other to form a bag-shaped packaging material 31.

Then, inside the packaging material 31, that is, between the outer film 33 and the inner film 34, a sheet-like food 37 such as seaweed or kelp is enclosed, and the inner films 34, 34 are contacted with the triangular rice ball rice 36. It is configured to be wrapped.

When the packaging material 31 enclosing the triangular rice ball rice 36 as described above is opened, first, the opening tape 32 is pulled and removed, and the outer film 33 is cut into two.

Also, since the inner films 34, 34 are divided into two pieces from the beginning and the edges are heat-sealed to the outer film 33,
When one of the divided packaging materials 31 is pulled, the outer film,
It is also removed together with the inner film, and half of the seaweed or kelp is wrapped around the triangular rice ball rice 36.

Similarly, if the other half of the packaging material 31 is removed, the entire outer circumference of the triangular rice ball rice 36 becomes a rice ball wrapped with seaweed or kelp.

However, in the packaging material 31 as described above, the ninth
As shown in the figure, triangular rice ball rice 36 has adhesiveness,
When pulling the packaging material 31 divided into two parts, the inner films 34, 34 and the triangular rice ball rice 36 are referred to as JIS so-called 0.
° Peeling does not occur easily, and the triangular rice ball rice 36 is pulled while the packaging material 31 is still attached to the packaging material 31.
It had the problem of causing damage such as cracking.

This invention solves the above-mentioned problems of the conventional ones, and when pulling each of the two-divided packaging materials, the contained material and the film are easily separated from each other and the contained material is not damaged. An object of the present invention is to provide a packaging material that enables the above.

[Means for solving problems]

In order to solve the above problems, the present invention provides an outer film and a pair of inner films which are superposed on the upper surface of the outer film and whose inner portion is superposed at a substantially central portion in the width direction of the outer film. In the packaging material having a sheet-shaped food product between the outer film and the inner film, the outer film has a strong resistance to the tensile force in the longitudinal direction of the film, but the width direction. With respect to the pulling force on the outer film, a synthetic resin film that is easy to tear is formed, and a notch for opening is formed at a substantially central portion on one side in the width direction of the outer film. The inner film of the outer film is bent outward to form a folded portion, and the folded portions are polymerized, and the folded portion is contacted with triangular rice ball rice to be wrapped. It is obtained by constituting the packaging material characterized by.

[Action]

This invention adopts the above-mentioned means, and the folded portion is provided on the inner film that comes into contact with the triangular rice ball rice, and the outer film is formed by the uniaxially stretched film, and the cut for opening is made. When removing the divided packaging material from the triangular rice ball rice, the inner film is peeled off so that it gradually turns from the folded back part to the triangular rice ball rice. Sheet-like food such as seaweed and kelp stored between the film and the film will be wrapped around the entire circumference of the triangular rice ball rice.

〔Example〕

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

FIG. 1 shows a first embodiment of a packaging material according to the present invention, and this packaging material 1 uses one synthetic resin film.

This synthetic resin film has a longitudinal direction (A
Direction) is easy to tear, but has a strong resistance to the tensile force in the width direction orthogonal to it, so-called uniaxially stretched film, strong against the tensile force Two notches 2 and 2 for opening which are oriented in the longitudinal direction are provided at predetermined intervals in the widthwise central portion having resistance.

In addition, the portions on both sides in the axial direction are folded back to the upper side through the bent portions 3 and 3, and the outer film 4 is retained at the remaining center portion.
In addition, the inner films 5 and 5 are formed by the folded back portions, and the end portions of the both inner films 5 and 5 are bent to form a bent portion 6,
The folded-back portions 7 and 7 are formed by folding back further through 6 to form the folded-back portions 7 and 7 so that the central portions of the outer film 4 are overlapped with each other.

Further, as shown in FIG. 2, a seal 8 is provided between the outer film 4 and the inner films 5 and 5 at four peripheral edge portions excluding the vicinity of the cuts 2 and 2, and the seaweed or the like stored inside is sealed. Allow the sheet food to be positioned.

The seal 8 may be a spot seal or an entire surface seal, and the packaging material 1 is formed by this.

In the packaging material 1 configured as described above, first, the second
As shown in the figure, the top of the triangular rice ball rice 20 faces the two cuts 2 and 2, and the bottom is positioned so as to be substantially in the center 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. Both corners 1
Fold 1 and 11 to cover the inclined surface of the triangular rice ball rice 20, and fold both corners 12 and 12 of the other half 9 together with both corners 11 and 11 in the direction of arrow B, and then to both corners. Secure with labels 13 etc. so that 12 and 12 are not released (Fig. 4).

Then, when eating rice balls, the film forming the packaging material 1 is a uniaxially stretched film by picking a portion formed between the two cuts 2 and 2 and making a round of the rice ball, and Since the direction in which the portion between the notches 2 and 2 is pulled is the stretching direction in which tearing is easy, it can be easily torn and the outer film 4 can be divided into two parts, at which time the label is also torn open.

On the other hand, since the inner films 5 and 5 and the folded portions 7 and 7 are originally divided, it is not necessary to divide them again.

When one of the two divided 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 which is the sheet-shaped food product 14 is as shown in FIG. Therefore, the inner film 5 is peeled off so that the folded portions 6 are sequentially moved outward and the folded portions 7 are sequentially flipped off from the triangular rice ball rice 20, resulting in so-called JIS 180 ° peeling (see FIG. 6). As a result, it is possible to easily remove one of the divided parts and bring the seaweed into contact with the triangular rice ball rice 20, and the other part as well.

Therefore, there is no possibility that the onigiri will be rubbed by the folded-back portion 7 and damaged when peeled off.

FIG. 7 shows a second embodiment of the packaging material according to the present invention.

In the packaging material 21 shown in this embodiment, a uniaxially stretched film is used for one square outer film 24, and another film such as a polyethylene film is used for the two square inner films 25, 25. Is used.

Then, the uniaxially stretched film, which is the outer film 24, is stretched in the stretching direction, that is, the direction of easy tearing is in the direction of the arrow A, and the two slits are formed at predetermined positions in the central portion of the outer film 24 in the width direction. 22 and 22 are provided.

On the other hand, the two inner films 25, 25 are provided with folded portions 27, 27 via the folded portions 26, 26, and the folded portions 27, 27 are formed.
In a state where they are overlapped with each other in the substantially central portion of the outer film 24, and in a state in which the peripheral edge portions are matched with each other, they are overlapped with the upper surface of the outer film 24, and the outside except for the vicinity of the notches 22 and 22. The four peripheral edges of the film 24 and the inner film 25 are adhered 17 to form a packaging material 21.

It should be noted that the sheet-shaped food is previously stored between the outer film 24 and the inner film 25.

Therefore, even in the packaging material 21 configured as described above, the triangular rice ball rice is coated as in the first embodiment.

And when eating rice balls, make a cut in the above two places
If the part formed between 22 and 22 is picked up and the rice ball is wrapped around the rice ball, the film forming the outer film 24 is a uniaxially stretched film, and the part between the notches 22 and 22 tears in the direction in which it is pulled. Since the stretching direction is easy, the outer film 24 can be easily torn and the outer film 24 can be divided into two parts. At this time, the label is also torn apart.

On the other hand, since the inner films 25, 25 and the folded portions 27, 27 are originally divided, it is not necessary to divide them again.

Then, pulling one of the two divided parts in the lateral direction,
The inner film 25 is peeled off so that the bent portions 26 sequentially move outward and the folded portions 27 are sequentially flipped from the triangular rice ball rice, thereby easily separating one of the divided portions of the packaging material 21. Once removed, the seaweed can be brought into contact with the triangular rice ball rice, and the other part can be done in the same way.

Therefore, there is no possibility that the rice ball will be rubbed by the folded-back portion and damaged when peeled off.

[Effect of device]

The present invention has the following effects by being configured as described above.

First, since we used a uniaxially stretched film for the outer film,
It can be easily torn by simply picking the gap between the cuts and going around the rice ball once.

Also, by providing a fold-back portion on the inner film so that the fold-back portion comes into contact with the triangular rice ball rice, it is pulled from the triangular rice ball rice so that the fold-back portion of the inner film can be flipped when opening after tearing the outer film. It will be peeled off and can be pulled apart with a small force, so the triangular rice ball rice will not be damaged.

Furthermore, since the uniaxially stretched film is used as the outer film that tears when eaten, it is not breathable before tearing, and therefore, the sheet-shaped food product housed inside does not have a risk of getting damp.
