Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a packaging material, and more particularly to a packaging material used for packaging triangular rice ball rice and sheet food such as seaweed together.

[Prior art and problems to be solved]

Generally, there are various packaging forms such as rice balls and seaweed rolls sold at convenience stores and the like, which can be roughly classified into triangles, quadrangles, and variations thereof.

Among them, as a conventional packaging material whose form belongs to a quadrangle, there is a packaging material for packaging rice balls as shown in FIGS. 7 and 8.

That is, this packaging material for rice balls is composed of a film 21 on the front surface side and two films 22 on the back surface side which are overlapped with each other in the longitudinal center portion of the film 21 on the front surface side.
a and 22b, and their peripheral portions are heat-bonded 25 to form a bag-shaped packaging material.

In this case, the film 21 on the front surface side and the films 22a, 22b on the back surface side are easily heat-bonded, but the film on the back surface side
22a and 22b are treated so as not to be heat-bonded to each other.

Then, when using the packaging material, first, between the film 21 on the front surface side and the film 22a, 22b on the back surface side, for example, kelp or seaweed 26 which is a sheet-shaped food is stored, and the back surface side A triangular rice ball rice 27 is wrapped on the upper surfaces of the films 22a and 22b, and the ends are fixed with labels or tapes, and the rice balls are commercially available as rice balls.

When eating this wrapped rice ball, peel off the label or tape that stops the end, put triangular rice ball rice 27 on the film 22b on the one back side, and the film on the other back side Pick up the overlapping part of 22a and pull it to peel it from the film 21 on the front side
After exposing 26 etc. and moving the triangular rice ball rice 27 to the upper surface of this exposed seaweed 26 etc., this time peel off the film 21 on the front side by pulling by pulling on the end of the film 22 b on the one back side Expose the rest of the seaweed 26, etc., and wrap the triangular rice ball rice 27 in this part to complete the rice ball.

Therefore, the above-mentioned packaging material has a problem that it takes time to make a rice ball wrapped with seaweed, and there is a demand for a packaging material that can be more easily wrapped with seaweed.

The present invention solves the problems of the conventional ones described above, and can be opened in the packaged state, and by simply removing it, a sheet food such as seaweed can be wrapped around triangular rice ball rice. An object is to provide a packaging material that can be easily opened.

[Means for Solving the Problems]

In order to solve the above problems, a rectangular shape having a width direction and a longitudinal direction is formed, and at least the longitudinal direction is a stretched film, which is a center portion in the width direction, From the U-shaped notch facing the other end in the longitudinal direction, which is the unsealing direction, toward one end in the direction, and the streak extending to the one end side in the longitudinal direction that is continuous with the central portion of the part facing the width direction of the notch. And a film on the surface side on which the cut portion is formed, and two sheets that are folded back and overlap each other with the folded back portion facing up, and the peripheral edge portion of the non-folded back portion is adhered to the surface side film. And a sheet-shaped food such as seaweed is stored between the film on the front surface side and the film on the back surface side, and a triangular rice ball is formed on the upper surface of the folded back portion of the back surface film. In addition to folding and wrapping in a position, the label is fixed and sealed while covering the cut portion, and the packaging material is configured to be opened using this label. is there.

[Action]

This invention adopts the above means, and when the inner part of the U-shaped cut made on the film on the front surface side is pulled in the longitudinal direction of the film on the front surface side, the width corresponding to the width from the cut is substantially equivalent. By sequentially tearing and separating the portion from the film on the front surface side in the stretching direction, the film on the front surface side is divided into two in a state where one end portion is continuous. Then, when one of the films on the front surface side of the two-divided portion is separated and removed, the continuous portion is easily divided by the streak, and the front-side film is divided into two. Then, the two films on the rear surface side, which are respectively adhered to the front surface side that is divided into two, are also divided into left and right.

Therefore, the sheet-shaped food such as seaweed or kelp stored between the film on the front surface side and the film on the back surface side is wrapped around triangular rice ball rice to complete the rice ball.

Then, the film on the back side is folded back, and the upper surface of the folded back portion is in contact with the triangular rice ball rice, so when the film on the back side is pulled left and right, the film on the back side is triangular rice ball rice. Since it will come off rather than rub against it, there is no risk of the triangular rice ball breaking.

〔Example〕

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

1 to 3 show an embodiment of the packaging material according to the present invention.

In the packaging material shown in this example, a rectangular biaxially oriented polypropylene film having at least the longitudinal direction as the stretching direction is used as the film 1 on the front surface side.

Then, as a procedure for opening, in the opening direction, that is, the U-shaped notch 10 that faces the longitudinal direction, and the central portion of the notch 10 that faces the width direction is connected to one end side in the longitudinal direction. A cut portion 12 including an extending stripe 11 is provided. Then, the cut portion 12 is provided at the center portion in the width direction of the film 1 on the front surface side and closer to one end than the center portion in the longitudinal direction.

The portion surrounded by the cut 10 is the tongue portion 10a.

Then, the thermal adhesive resin 5 is applied to the peripheral portion excluding the vicinity of the central portion in the width direction so as not to hinder the cutting of the film 1 on the front surface side when opening.

Next, the back side films 2a and 2b made of two high-density polyethylene films are folded back on the back side of the front side film 1 as described above, and the folded back portions are placed on top of each other.

Then, the overlapped portion faces the longitudinal direction of the film 1 on the front surface side, is positioned so as to be located in the central portion of the film 1 on the front surface side, and further covers the cut portion 12.

And the film 1 on the front side and the films on both back sides
The peripheral edge portion between the unfolded portion of 2a and 2b is thermocompression-bonded, and the film 1 on the front side and the film 2 on the back side
The peripheral portion between a and 2b is adhered to form a packaging material.

At this time, the sheet-shaped food, for example, seaweed 6, is housed between the film 1 on the front surface side and the films 2a and 2b on the back surface side.

That is, the method for storing the seaweed 6 is as follows.
And the backside films 2a and 2b are adhered to each other and the seaweed 6 is housed therebetween, or the front side film 1
There is a method of storing the seaweed 6 by inserting the seaweed 6 into the space formed between the film 2a and the film 2b on the back side.

When the packaging material formed as described above is used, first, the half of the upper surface of the folded back portion of the backside film 2a, 2b,
1. The triangular rice ball rice 7 is placed so that the notch 12 for opening provided in FIG. 1 is located substantially in the center, that is, as shown in FIG.

Next, the other side of the longitudinal direction of the packaging material is folded back, so that the other half of the upper surface of the folded back portion of the films 2a, 2b on the back side contacts the triangular rice ball rice 7, , Triangular rice ball rice 7 should be sandwiched between packaging materials.

After this, the corners on one side in the longitudinal direction of the packaging material are bent to cover the slope of the triangular rice ball rice, and the corners on the other side are bent in the opposite direction to the corners on the one side. After covering both side corners, stack them.

As a result, the two corners on the other side are located in the vicinity of the cut portion 12 and do not overlap the cut portion 12.

Then, the label 9 is attached so as to cover the cut portion 12 and to lock the overlapping portion of both corners on the other side (FIG. 3), and the packaging is completed.

The adhesive surface of the label 9 may be the entire surface, or the non-adhesive portion to which the adhesive is not applied may be formed on the upper end portion and the entire surface may not be the adhesive portion.

When eating rice balls stored inside the packaging material as described above, first, the label 9 is peeled off in the direction of arrow A as shown in FIG.
The tongue portion 10a, which is the inner portion of the film 10, is the film 1 on the front
(Fig. 5).

Then, when the label 9 is pulled in the longitudinal direction, the film 1 on the front surface side is formed of a stretched film that is easily torn in the longitudinal direction, so that the film 1 on the front surface side can be easily formed with a width substantially corresponding to the width from the notch 10. It can be torn (Fig. 6).

Further, by making a round of the label 9, the film 1 on the front side
Can be divided into two along the band of the width of the notch 10 with one end thereof being continuous. In addition, there are lines 11 in the notch 10.
Since the continuous portion that is not divided into two is provided by the stripe 11 extending like the chain line shown by X in FIG. 6 when pulling one side of the film 1 on the surface side and separating it, Film 1 is divided into two.

Further, the film 1 on the front surface side and the film 2a on the back surface side,
Since only the peripheral portions of 2b are heat-bonded to each other, the front side film 1 is divided into two at the central portion, and the front side film 1 is simply pulled to the left or right to form the back side film.
2a and 2b are also pulled to the left and right in a state of being adhered to each of the two divided films 1 on the front surface side.

At this time, the films 2a and 2b on the back surface side are pulled left and right with the triangular rice ball rice 7 in contact with the upper surface of the folded back portion.

When the backside films 2a and 2b are pulled to the left and right, the backside films 2a and 2b are peeled off from the triangular rice ball rice 7 so that the backside films 2a and 2b are removed from the triangular rice ball rice 7. Will not rub.

In this way, when pulling the films 2a, 2b on the back side to the left and right, there is no fear that a force that breaks the triangular rice ball rice 7 will act.

Further, since the film 1 on the surface side is only in contact with the seaweed 6, it can be easily pulled to the left and right.

Therefore, by simply pulling the divided film 1 on the front side to the left and right, the seaweed 6 which is a sheet-shaped food can be easily wrapped around the entire circumference of the triangular rice ball rice 7 without breaking the triangular rice ball rice 7. You can complete a rice ball.

In the examples, the biaxially stretched film was used as the film 1 on the front surface side, but it is not limited to this, and may be a uniaxially stretched film. In short, the film 1 on the front surface side is
It suffices if it is formed of a stretched film in which at least the longitudinal direction is the stretching direction.

[Effect of device]

This invention uses a stretched film for the film on the front side, and makes the stretch direction that tears easily the longitudinal direction, and at the center of the width direction, near the one end of the longitudinal direction, a U-shaped cut facing the longitudinal direction. , A cut part consisting of a stripe extending to one end in the longitudinal direction connected to the central part of the width direction part of the cut, and when the triangular rice ball rice is wrapped, the cut part is sealed with a label. Since it is positioned, it is possible to easily tear the film on the surface side from the notch to the longitudinal direction which is the stretching direction by simply grasping and pulling the label at the time of opening. It can be divided.

Therefore, the label can be used both as a seal at the time of packaging and as a pick at the time of opening, the number of constituent members is small, and it can be manufactured at low cost, and at the same time, it is possible to clarify the opening position at the time of opening.

In addition, since one end side that is continuous has a streak formed, it is possible to easily and surely reach the end at the streak position simply by pulling apart the surface-side film divided into two parts to the left and right. It can be divided, so that sheet-shaped food such as seaweed can be brought into contact with triangular rice ball rice without opening mistakes.

Therefore, as a procedure for unsealing, in the center portion in the width direction of the film on the front surface side, at a position close to one end in the longitudinal direction, the notch and the center portion of the notch in the width direction are connected. It suffices to provide only a notch formed by a stripe extending to one end side in the longitudinal direction, and it is not necessary to attach another member such as an unsealing tape to the film on the surface side.
It is easy to process and the manufacturing cost is low.

Further, the back side film is provided with a folded back portion, and since the folded back portion comes into contact with the triangular rice ball rice, when the back side film is pulled left and right, it peels off so that the front side film is There is no danger of rubbing triangular rice ball rice and breaking it, it is easy and
You can surely make triangle rice ball rice wrapped with sheet food.

Further, since the cut portion is covered with the label before opening, the front side film has no air permeability at all, and there is an effect that the sheet-shaped food stored inside is not likely to get wet.
