Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a packaging material for rice balls.

[0002]

2. Description of the Related Art Rice balls are popular because they can be eaten easily, and they sell well at supermarkets and convenience stores.

This packaging material for rice balls is made by forming a synthetic resin film into a bag shape and sandwiching a sheet-shaped food product such as seaweed into the bag. The rice ball and the sheet-shaped food product are in contact with each other until just before eating. I was trying not to. Then, when eating, the bag was torn from the center and the sheet-shaped food was covered with rice and then eaten (for example, JP-A-9-2523).

However, these foods produce dusts made of synthetic resin film after they are eaten, and when the dusts are burned, the dusts become high in temperature and damage the incinerator, and the secondary substances produced by the incineration pollute the environment. There was a problem that it caused the problem, and when dust was scattered on the ground, it remained without being disassembled forever.

Therefore, it has been considered to make a packaging material using paper so that the dust generated after eating is easily decomposed naturally and has little environmental pollution, but it looks delicious if the inside is not visible. Since there is no rice ball, there is a problem that rice balls wrapped with paper packaging materials cannot be sold.

[0006]

Therefore, according to the present invention,
An object of the present invention is to provide a packaging material for rice balls that is naturally gentle and allows the sheet-shaped food inside to be seen through the exterior material as in the conventional case.

[0007]

Therefore, according to the present invention, the opposite sides 5a, 6a are overlapped with each other on the outer edges of the opposite sides of the outer package 1 made of rectangular transparent paper at approximately the center of the outer package 1. Join the interior materials 5 and 6 made of transparent paper,
Further, a sheet-shaped food 7 is sandwiched between the exterior material 1 and the interior materials 5, 6 to provide a rice ball packaging material.

According to the above, since the exterior material 1 and the interior materials 5 and 6 are made of paper, not only does it emit a high temperature even when incinerated, but also no harmful substance is produced. Even if left on the ground as dust, it is easily decomposed naturally.

Further, since the exterior material 1 is made of transparent paper and the sheet-shaped food 7 can be seen through the exterior material 1, the consumer's willingness to purchase is not impaired.

The transparent paper used for the exterior material 1 and the interior materials 5, 6 may be moisture-proof cellophane paper having thermal adhesiveness or glassine paper coated with a thermal adhesive layer.

It is preferable to attach a cut tape 2 or a cut thread 2 made of a cotton thread to the inside of the exterior material 1 substantially at the center thereof.

As described above, the use of the cut tape or the cut yarn 2 makes it easier to tear the exterior material 1. further,
If a cotton thread is used as the cut thread 2, the cut thread 2 will be naturally decomposed.

FIG. 3 is a rear view showing a state in which the packaging material for rice balls of the present invention is used for packaging. Embodiments of the present invention will be described below with reference to these drawings.

Reference numeral 1 is a rectangular exterior material made of transparent paper,
The cut yarn 2 is attached in parallel to the long side of the exterior material 1 at a substantially central portion on the short side. Furthermore, a pair of cut lines 3 and 3 are formed on both sides of the cut yarn 2 at the outer edge on the short side, and an opening operation piece 4 is formed.

The cut yarn 2 is a cotton yarn, which is attached by arranging the cut yarn 2 along the inside of the exterior material and pressing it with a heated roller.

Reference numerals 5 and 6 denote a pair of interior materials, one side of which is heat-bonded to the outer edge of the exterior material 1 on the long side, and the opposite sides of the interior materials 5 and 6 at the approximate center in the width direction of the exterior material 1. 5a and 6a are overlaid. Further, the interior materials 5 and 6 are made of transparent paper.

As the transparent paper used for the exterior material 1 and the interior materials 5 and 6, moisture-proof cellophane paper having thermal adhesive property, glassine paper coated with thermal adhesive, and heatlon paper coated with paraffin wax on one side. Those having increased transparency and moisture resistance are used.

Moisture-proof cellophane paper having heat-adhesive property is, specifically, a vinyl chloride-based adhesive such as a vinyl chloride copolymer or vinylidene chloride copolymer is applied to cellophane paper to obtain moisture-proof and heat-adhesive properties. And the like. Paraffin wax, polyvinyl alcohol, polyethylene emulsion and the like are adopted as the thermal adhesive applied to the glassine paper.

The transparency of the glassine paper is preferably 50% or more, but may be such that the sheet-shaped food 7 can be seen.

Further, when glassine paper is used, it is preferable to use wood pulp of 100% so that it is easily decomposed.

The exterior material 1 and the interior materials 5 and 6 are adapted to be adhered to each other by melting the vinyl chloride copolymer, paraffin wax or the like applied on the surface by heating.

Reference numeral 7 denotes a sheet-shaped food product sandwiched between the exterior material 1 and the interior materials 5, 6 and is selected from, for example, seaweed, bonito flakes and kelp and the like formed into a sheet shape with gelatin.

Next, an example of packaging rice balls using the packaging material of this embodiment will be described. First, as shown in FIG. 1, the packaging material for rice balls of the present invention is placed with the interior materials 5, 6 facing upward.

Next, the triangular rice ball rice 8 is placed on the interior materials 5 and 6, wrapped with a rice ball packing material, and the ends thereof are stopped by a roll-sealing seal 9, as shown in FIG.

Then, the state shown in FIG. 3 is obtained, and the item is sold in this state. The packaging material for rice balls of the present invention is packaged by a conventionally known packaging device.

When eating this rice ball, pulling the unsealing piece 4 of the exterior material 1 causes the exterior thread 1 to be split along the cut threads 2 because the cut threads 2 are attached.

Next, when the cut right half of the exterior material 1 and the cut interior material 6 are pulled to the right in the figure, the right half of the nigiri rice 8 is covered with the sheet-shaped food 7.

Furthermore, when the left half of the exterior material 1 and the interior material 5 are pulled leftward in the figure, the left half of the nigiri rice 8 is also covered with the sheet-shaped food 7.

The above is the description of the packaging material for rice balls of the present invention, and a cut tape can be used instead of the cut yarn 2.

The cut tape usually used has a width of 3 mm, but it is preferable that the cut tape has a wide width of about 5 mm to 10 mm, preferably 6 mm. This is because if the width of the cut tape is wide, the exterior material 1 is largely torn, the friction with the sheet-shaped food 7 is reduced, and the work of covering the sheet-shaped food 7 is facilitated when eating.

[0031]

As described in the above embodiments, the packaging material for rice balls of the present invention does not use a plastic sheet as in the conventional case, but uses transparent paper. Not only there are few problems of damage and environmental pollution, but even if they are left on the ground, they are easily decomposed naturally and environmental pollution is small.

If the transparent paper used for the exterior material 1 and the interior materials 5, 6 is moisture-proof cellophane paper, the transparency will be good, and if the thermal adhesive layer is applied to glassine paper, the cost can be reduced.

It is preferable that a cut tape 2 or a cut thread 2 made of a cotton thread is attached to the inside of the exterior material 1 substantially at the center thereof.

When the cut tape or the cut yarn 2 is used, the exterior material 1 is easily torn and eaten easily.

Further, when the cut yarn 2 made of cotton yarn is used, the cut yarn is naturally decomposed, so that it is less likely to affect the environment.
