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, the seaweed or kelp 26 which is a sheet 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 To expose the rest of the seaweed 26, etc., and wrap this part in triangular rice ball rice 27 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.

This invention solves the problems with the conventional ones described above, and can be opened from the packaged state, and by simply removing it, a sheet food such as seaweed can be wrapped around triangular rice ball rice. It is also an object of the present invention to provide a good packaging material by simply subjecting the film on the surface side to simple processing.

[Means for Solving the Problems]

In order to solve the above-mentioned problems, while forming a rectangular shape having a width direction and a longitudinal direction, it is composed of a uniaxially stretched film having the longitudinal direction as a stretching direction, at one side of the central portion in the width direction, and unsealed. A film on the surface side having a notch having a U-shaped notch facing the longitudinal direction which is the direction,
The two films on the back surface side are adhered together with the film on the front surface side while the center parts are polymerized with each other, and the peripheral edge part except the polymerized part is substantially coincident with the peripheral edge part of the film on the front surface side. And a sheet food such as seaweed is stored between the film on the front side and the film on the back side,
In the vicinity of the cut portion by sequentially folding both corners on both sides in a state where the film on the back side is in contact with triangular rice ball rice, and at a position not overlapping the cut portion, the cut portion of the film on the front surface side With the both corners on the side not being positioned, the label is attached so as to cover the cut portion, and is held in this state and sealed, and when the label is peeled off, the The packaging material is characterized in that the front side film is divided in the longitudinal direction by separating a portion having a width corresponding to the width from the front side film.

[Action]

This invention adopts the above means, and when the label covering the U-shaped cut made on the film on the surface side is peeled off, the inside of the cut is attached to the label and separated from the film on the surface side, When the label is pulled in the longitudinal direction of the film on the front surface side, a portion having a width substantially corresponding to the width is torn from the notch and separated from the film on the front surface side, whereby the film on the front surface side is divided into two. . Then, when the film on the front surface side that is divided into two is removed to the left and right, the two films on the back surface side that are respectively bonded to the film on the front surface that is divided into two are also divided into the 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.

〔Example〕

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

FIG. 1 and FIG. 2 show an embodiment of the packaging material according to the present invention.
A square uniaxially stretched polypropylene film whose longitudinal direction is the stretching direction is used as the film 1 on the front surface side.

Then, as a procedure for opening, the U-shaped notch 10 that faces the opening direction is the central portion in the width direction, and
It is provided closer to one side than the central portion in the longitudinal direction.

Further, the notch 10 is provided with a longitudinally oriented stripe 11 for dividing the film 1 on the front surface side at the center thereof.

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.

Then, on the back surface of the film 1 on the front surface side as described above, the films 2a, 2b on the back surface side made of two high-density polyethylene films are overlapped with each other by 1 cm or more, and Facing the longitudinal direction, and
It is positioned so as to be located in the center of the film 1 on the front surface side, the peripheral edge portion is thermocompression bonded, and the peripheral edge portion between the film 1 on the front surface side and the films 2a, 2b on the rear surface side is adhered and packaged. Form the 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 seaweed 6 is placed on the upper surface of the film 1 on the front surface side, and the films 2a and 2b on the rear surface side are further mounted on the upper surface thereof, and the film 1 on the front surface side and the film 2 on the rear surface side are placed.
A method of adhering between a and 2b and storing them between the two, or a method of inserting seaweed 6 into the void formed between the film 1 on the front surface side and the films 2a, 2b on the back surface side Etc.

When the packaging material formed as described above is used, first, the opening notch 12 provided in the film 1 on the front surface side is substantially formed in the half of the upper surface of the film 2a, 2b on the back surface side. The triangular rice ball rice 7 is placed so as to come to the center, that is, at a position closer to one side in the longitudinal direction as shown in FIG.

Next, the other side in the longitudinal direction of the packaging material is folded back so that the other half of the upper surface of the backside film 2a, 2b contacts the triangular rice ball rice 7, that is, the triangular rice ball rice 7 is used as the packaging material. Make sure to sandwich it.

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.

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 inside of 10 is separated from the film 1 on the front side (Fig. 5),
Further, when the label 9 is pulled in the longitudinal direction, the film 1 on the front surface side is formed of a stretched film which is easily torn in the longitudinal direction, so that it can be easily torn from the notch 10 with a width substantially corresponding to the width ( (FIG. 6), by making one turn around the label 9, most of the film 1 on the front surface side can be divided into two along the strip-shaped state of the width of the notch 10.

In addition, since the notch 10 is provided with a streak 11,
The remaining part which is not divided is divided into two because the streak 11 extends like the chain line shown by X in FIG. 6 when the film 1 on the front surface side is pulled left and right.

Even when the streak 11 is not provided, the force is concentrated on the corners of the notch 10 when pulling the film 1 on the front side to the left and right, so that the film 1 on the front side is divided.

Further, the film 1 on the front surface side and the film 2a on the back surface side,
Since only the peripheral portions thereof are heat-bonded to 2b, when the film 1 on the front surface side is divided into two parts at the substantially central portion and separated, the films 2a and 2b on the back surface side also follow the film on the front surface side. Separated in the state of being adhered to each of 1,
The packaging material can be easily pulled out.

Furthermore, the packaging material can be easily pulled out, and since the sheet-shaped food, seaweed 6, is stored inside, this seaweed 6 can be easily wrapped around the entire circumference of the triangular rice ball rice 7 to make a rice ball. Can be completed.

[Effect of device]

This device has the following effects by being configured as described above.

First, using a uniaxially stretched film for the film on the surface side, the stretching direction that easily tears is the longitudinal direction, and a U-shaped cut facing the longitudinal direction is applied to the central portion in the width direction, further,
Since a label covering this cut is attached at the time of packaging, the triangle rice ball rice can be easily opened in a packaged state and the packaging material can be divided into two simply by peeling the label and pulling.

Therefore, the sheet food such as seaweed can be brought into contact with the triangular rice ball rice simply by pulling the divided packaging material.

Further, since the cut portion is sealed with a label before opening the film on the front surface side, it has no air permeability, the outside air does not come into contact with the sheet food such as seaweed, and the sheet food does not get wet.

Further, it is not necessary to attach a separate member such as an opening tape to the film on the front surface side, and it is only necessary to make a notch so that it is easy to process, and the manufacturing cost is low. .
