Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a packaging material, and particularly to a packaging material used for packaging rice balls.

[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 by shape into square, triangular, and other variations. Can be classified.

Among these, as a conventional packaging material belonging to the rectangular shape, there is 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 pieces excluding the part that is pasted 15
and the exterior material film 13 and the interior material film 1
4 and 14 are integrated to form a bag-shaped 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.
The packaging material 11 is divided into two pieces and the edges are heat-sealed to the exterior material film 13.
When one side is pulled, the exterior material film and the interior base material film are removed together, and half of the seaweed or kelp is wrapped around the rice ball 16.

Similarly, if the other half of the packaging material 11 is removed,
The entire outer circumference of the rice ball 16 is wrapped with seaweed or kelp.

However, in the case of the packaging material 11 described above, as shown in FIG. Because of the nature of
When pulling the packaging material 11 divided into two parts,
The interior material films 14, 14 and the rice ball 16 are
Packaging material 11 cannot be easily peeled off due to its adhesiveness.
There was a problem in that the rice ball 16 was pulled while 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 packaging materials that prevent damage.

[Means for solving problems]

In order to solve the above problems, this invention has an opening strip in the center, and is formed by folding one side on one side of the exterior material film coated with low-temperature thermoadhesive resin on the four peripheries. An interior material film is formed from two films that are polymerized so that the folded portion is on the opposite side of the exterior material film and has the same size as the exterior material film, and the polymerized portion is along the opening strip. located as,
Except for the vicinity of the strip for opening, the four peripheral edges of the exterior material film and interior material film are thermally bonded using the low-temperature thermoadhesive resin to form a bag, and a sheet-like wrapping is placed inside the bag. At the same time as storing the item, the item is covered and packaged with the interior material film inside, and when the item is opened, the item is still wrapped and the exterior material film is divided into two using the opening strip. At the same time, by pulling one of the divided exterior material films, the interior material film that is thermally bonded to the one exterior material film,
The folded part is peeled off from the stored item, and is integrated with the one exterior material film and separated by a strip leaving the wrapped item.

[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 integrated with the exterior material film by thermal bonding, 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, in which a tear tape 2 is pasted from the center of one end to the center of the opposite end.
A rectangular exterior material film 3 made of biaxially oriented polypropylene, which is a polyolefin in-film coated with a low-temperature thermal adhesive resin on the peripheral edge, and a folded portion on the outside thereof, and the above-mentioned An interior material formed of two rectangular films made of high-density polyethylene that overlap in the same direction as the opening tape 2 and have the same size as the exterior material film in the overlapped state. A bag-shaped packaging material 1 is formed by overlapping the films 4, 4 and thermally bonding 5 the peripheral edges of the four, excluding only the peripheral edge of the part to which the tear 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 nori or kelp is enclosed inside the bag-shaped packaging material 1 to which the four peripheral edges are adhered, and the folded parts 7, 7 of the interior material films 4, 4 are sealed.
Touch rice ball 6 and wrap rice ball 6 with packaging material 1.
Wrap it as shown in Figure 3.

Therefore, when the rice ball is packaged as a storage item, the four peripheral edges of the exterior material film are bonded to the interior material film, so the seaweed stored between the exterior material film and the interior material film is Alternatively, wrapping items such as kelp are not likely to come into contact with the air, so there is no risk of them becoming damp due to the moisture of the rice balls, etc. Therefore, wrapping items such as kelp are always kept in the dry state when stored.

Next, the operation of the above will be explained.

When the packaging material 1 is opened, the tear tape 2 is first pulled and removed, and the exterior material film 3 on both sides of the tear tape 2 is provided with I-notches 3', 3'. Therefore, the exterior material film 3 is cut into two along these I notches 3', 3'.

On the other hand, the interior material films 4, 4 are
Since it is a single sheet and is thermally bonded 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 as if it were being removed.

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 the wrapping material sealed inside the interior 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, when opening the package, the exterior material film can be divided into two parts using the unsealing strip while the contents are still wrapped, and by simply pulling one of the divided exterior material films, one of the exterior material films can be heated. The glued interior material film is separated from one of the exterior material films so that the folded part is peeled off from the stored object, leaving the wrapping material behind, and the wrapped material is separated from the wrapping material on the rice ball. This means that objects can be brought into contact.

In addition, in the above 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.

In addition, in the above embodiment, the exterior material film and the interior material film were made of the same material, but sufficient adhesive strength can be obtained when the exterior material film and the interior material film are made of different materials. To achieve this, first coat an adhesive resin with good adhesion on the exterior material film, and then apply an adhesive resin with good adhesion on the interior material film, which is a so-called double coating. In this case, the adhesive resin that has good adhesion to the exterior material film does not need to be a thermal adhesive resin, and the adhesive resin that has good adhesiveness to the interior material film can be heat-adhesive. It needs to be an adhesive resin.

[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. Since the wrapped item is stored between the exterior material film and the interior material film, which have their four peripheral edges glued together, there is no fear that the wrapped item will become damp and can be eaten deliciously. This has the excellent effect of being extremely hygienic, with no fear of dust or the like adhering to the wrapping.
