Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a packaging material, and particularly to a packaging material used to package a container such as a rice ball.

[Prior art and its problems]

Generally speaking, packaging materials for rice balls sold at convenience stores, etc. are available in a variety of packaging formats, and they can be broadly categorized into square, triangular, and modified shapes. Can be classified.

Among these, a conventional packaging material whose shape belongs to a rectangle includes one for packaging rice balls as shown in FIG.

This rice ball packaging material 11 consists of a rectangular exterior material film 13 with a tear tape 12 attached from the center of one end to the center of the opposite end.
Then, two rectangular interior material films 14, 14 each having a width slightly larger than that obtained by dividing this exterior material film 13 into two in the longitudinal direction, are positioned so that their central portions overlap, and a tear tape is applied. 12
Heat-seal the four sides excluding the part where it is pasted 15
and the exterior material film 13 and the interior material film 1
4 and 14 are integrated into a bag-like packaging material 11.

Then, a wrapping material such as seaweed or kelp is sealed inside the packaging material 11, and the interior material film 1
4 and 14 are brought into contact with and wrapped around the rice ball 16.

When the packaging material 11 enclosing the rice ball 16 is opened as described above, the opening tape 12 is first pulled and removed, and the exterior material film is cut into two.

Moreover, the interior material films 14, 14 are set at 2 from the beginning.
Since it is divided into two sheets and the edges are heat-sealed to the exterior material film 13, when one of the two halves of the packaging material 11 is pulled, only one side of the packaging material 11 is removed and the seaweed or Half of the kelp is exposed and this exposed part of the seaweed or kelp is made into rice balls16.
Wrap it around.

After that, when the other side of the packaging material 11 is removed, the remaining seaweed or kelp is exposed, and when it is wrapped around the rice ball 16, the entire outer circumference of the rice ball 16 is wrapped with seaweed or kelp.

As for the packaging material 11 described above, as shown in FIG.
4 also has some adhesiveness, so when the packaging material 11 divided into two parts is pulled, the interior material films 14, 14 and the rice ball 16 are not easily peeled off due to their adhesiveness. Onigiri 16 in packaging material 11
The rice ball 16 may be pulled while it is still attached, causing damage such as the rice ball 16 breaking into two.

This idea solves the above-mentioned problems of the conventional method, and when the two halves of the packaging material are stretched, the rice ball and the interior material film easily separate, causing the rice ball to become The purpose is to provide interior materials that prevent damage.

[Means for solving problems]

In order to solve the above-mentioned problems, this invention involves folding one side of two interior material films on one side of the exterior material film having an opening strip in the center, so that this folded part is attached to the exterior material film. The polymerized portion is positioned along the strip for opening, and the peripheral edges of the exterior material film and interior material film are heat-sealed to form a bag shape. The winding material is stored inside the container, and the stored material is covered with the interior material film on the inside.

[Effect]

As mentioned above, this device is designed so that the folded part provided on the interior material film is located in the overlapping part of the interior material film that contacts the rice ball that is contained, so that it can be cut by the opening strip. When removing the packaging material formed from the exterior material film and the interior material film that is integrally heat-sealed to the exterior material film from the rice ball,
When the interior material film that is in contact with the rice ball is pulled, it is gradually peeled off from the folded portion, and when the interior material film is removed in this state, the exterior material film and the interior material film are separated. A wrapping material such as seaweed stored between the rice balls is wrapped around the entire outer circumference of the rice ball.

〔Example〕

Embodiments of this invention shown in the drawings will be described below.

FIG. 1 shows a packaging material 1 according to this invention, which is made of biaxially oriented polypropylene, which is a polyolefin film, with a tear tape 2 attached from the center of one end to the center of the opposite end. A package made of high-density polyethylene, which has a shaped exterior material film 3 and a folded portion on the outside, which overlaps in the same direction as the opening tape 2 at the center of the exterior material film 3. A bag-shaped packaging material 1 is formed by overlapping two shaped interior material films 4, 4 and heat-sealing 5 the four sides excluding the part to which the opening tape 2 is attached.

Therefore, as shown in FIG. 2, folded portions 7, 7 which are folded back outward are formed in the overlapped portions of the interior material films 4, 4, respectively.

Then, a wrapping material 8 such as seaweed or kelp is sealed inside the bag-shaped packaging material 1, and the interior material films 4, 4 are brought into contact with the rice ball 6, and the rice ball 6 is wrapped with the packaging material 1. Do as shown in the diagram.

Next, the operation of the above will be explained.

When opening the packaging material 1, first pull and remove the tear tape 2, and the exterior material film 3 on both sides of the tear tape 2 is provided with V-notches 3'. The exterior material film 3 is cut into two along this V-notch 3'.

On the other hand, the interior material films 4, 4 are
Since it is a single sheet and is heat-sealed to the exterior material film 3, when the exterior material film 3 is divided into two using the tear tape 2, the bag-shaped packaging material 1 is divided into two.

Then, when one of the two divided packaging materials 1 is pulled, as shown in FIG. It will be torn off.

That is, the folded portion 7 of the interior material film 4
will be peeled off from the rice ball 6 while sequentially moving outward.

Then, the seaweed or kelp 8, which is a wrapping material sealed inside the packaging material 1, does not move and is easily exposed from the packaging material 1, so that it can be wrapped around the rice ball 6.

Furthermore, the other side of the packaging material 1 is peeled off in the same way, and the remaining seaweed or kelp 8 is wrapped around the rice ball 6, thereby completing the rice ball.

In addition, in the above-mentioned example, the shape of the exterior material film and the interior material film was rectangular, but
It is not limited to this, and may have any shape.

[Effect of idea]

As mentioned above, this device provides a partially folded part in the interior material film on the side that contacts the stored object, so that when the interior material film that is in contact with the stored object is first pulled, As a result, the folded parts of the interior material film that are in contact with the stored items are continuously peeled off.
It does not require much force when pulling the interior material film, the packaging material can be easily removed without damaging the stored items, and the wrapping material can reliably come into contact with the stored items. It has excellent effects.
