Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a seaweed-wrapped rice ball packaging device that can package seaweed-wrapped rice balls and allow the user to eat crispy seaweed-wrapped rice balls when edible.

[Conventional technology]

Traditionally, seaweed-wrapped rice balls were made in advance and wrapped in cellophane or other film, but recently there has been a packaging material that allows the rice balls and seaweed to be wrapped separately and then eaten as seaweed-wrapped rice balls. developed and commercialized. For example, Jikko No. 57-10542 and Special Publication No. 59-
As shown in No. 41679, it consists of a double bag consisting of a triangular outer bag and an inner bag. Seaweed is inserted between the outer bag and the inner bag, and then the rice balls are placed inside the inner bag and the bag is sealed.
A packaging device and a method for using the packaging device have been developed in which the inner bag can be pulled out to make crispy seaweed-wrapped rice balls inside the outer bag when edible.

With these double-bag methods, not only was it time-consuming to wrap the rice balls, but there were many problems in automating the process.

Recently, various rice ball packaging tools have been developed to solve these problems. For example, as shown in FIG. 6, a rice ball packaging device is disclosed in which the inner central portions of bags are overlapped and seaweed is inserted therein. This rice ball packaging tool body 1
1, as shown in FIG. 6, a synthetic resin film is formed into a rice ball packaging material 12, the inside is cut to an appropriate length, an inner overlapped part 15 is provided in the center, and the inner overlapped part 15 and the rice ball are wrapped. Seaweed S is inserted between the packaging material 12 and the four corners are sealed.

First, as shown in FIG. 6, place the rice ball W on either side of the inner side 16 of the rice ball packaging main body 11, and insert the folding part 1 according to the shape of the rice ball W.
8 and then fold the other side in the same way (see Figure A) to create a wrapped rice ball H as shown in Figure B.
Next, when eating, remove the seal of the packaged rice ball H shown in Figure B, spread the rice ball packaging material 12 horizontally, and open the inside part 16 on the opposite side where the rice ball W is placed.
Turn it outward (see figure C). Then,
Roll the rice ball W half a turn, place it on the seaweed S, and then peel off the inner part 17 on the opposite side outward (see Figure 2). Further, as shown in Figure E, roll the rice ball W in the book position and wrap the seaweed S around the rice ball W with your hands to make a seaweed-wrapped rice ball.

This conventional method does not pose much of a problem when making packaged rice balls H, but it takes time and effort to make seaweed-wrapped rice balls for consumption, and in the end, the rice balls W have to be wrapped in seaweed directly, which is unsanitary. This poses a major problem in terms of hygiene.

There is also a packaging device for rice balls wrapped in seaweed, which was filed by the present applicant in Utility Application No. 83611/1983. This seaweed-wrapped rice ball packaging device, which has already been applied for, will be explained with reference to FIGS. 7 to 9. In the figure, 1 is the main body of the rice ball packaging device. The rice ball packaging material body 1 is a rice ball packaging material 2.
, a drawn material 7, and seaweed S.
The rice ball packaging material 2 is formed by molding a transparent synthetic resin film into a rectangular bag. A peel-off sticker 3 is placed approximately in the center of the surface portion 5 of this rice ball package 2.
is attached, and on the other hand, approximately the center portion of the back surface portion 6 is cut off. The peel-off sticker 3 is a red band-shaped sticker provided for peeling off the rice ball packaging material 2 and cutting it approximately in half, and is adhesively or press-sealed. The cut portion of the back surface portion 6 is provided so that the pull-out material 7 can be pulled out smoothly when the center portion of the rice ball packaging material 3 is opened by peeling off the peel-off sticker 3, as will be described later. It is. Reference numeral 4 denotes a pressure-bonding seal portion of the rice ball packaging material 2, and the nori seaweed S is inserted into the bag and sealed. Reference numeral 7 denotes a pull-out material that is attached to cover the cut opening portion of the back surface 6 of the rice ball packaging material 2 so that it can be pulled out when making seaweed-wrapped rice balls. This drawing material 7 is made of a semi-transparent film, and the resistance on the front and back surfaces is particularly reduced so that drawing is smooth. Note that, as shown in FIG. 8A and FIG. 8B, the drawn material 7 is coated from either the top or bottom of the back surface portion 6, and almost the same effect can be obtained.

Next, the usage state of the seaweed-wrapped rice ball packaging tool will be explained with reference to FIG. First, prepare the desired rice ball packaging body 1 containing seaweed and a triangular rice ball W, place the rice ball W on either side of the back surface 6 of the rice ball packaging material 2, and place the rice ball W on either side of the back surface 6 of the rice ball packaging material 2. Fold it in as shown in the figure, and then fold in the folded parts 8 on both sides.
When these are overlapped and sealed, a packaged rice ball H as shown in Fig. 4 is obtained. At this time, the peel-off sticker 3 of the rice ball packaging material 2 is made to protrude slightly so that it can be peeled off by pinching with fingers. Next, when eating, peel off the peel-off sticker 3 in the state shown in Figure C to open the almost central part of the rice ball packaging material 2, and then pull out the pull-out material 7 from the side as shown in Figure 2, as shown in Figure E. The seaweed-wrapped rice ball M is completed. Then, the rice ball wrapping material 2 can be eaten while being peeled downward with the seal 9 attached, or by pushing up the seaweed-wrapped rice ball M by hand. In other words, if you use this rice ball packaging tool, just peel it off and pull it out.
You can make crispy seaweed-wrapped rice balls.

However, in the seaweed-wrapped rice ball packaging devices shown in FIGS. 7 to 9 described above, the pull-out material 7 has the same dimensions as the width direction of the rice ball packaging material 2 and is relatively wide rectangular, so the peel-off sticker cannot be peeled off when eating. ,
When trying to push out the seaweed S and then pull out the pullable material 7, there was a problem in that since there was little and wide gripping space, there was a large resistance and it was difficult to pull out.

[The problem that the idea aims to solve]

The problem to be solved by the present invention is to solve the above-mentioned conventional problems. In other words, in the nori-wrapped rice ball packaging tool,
We provide a nori-wrapped onigiri packaging tool that allows the packaging to be automated using machines, as before, while making it easier than ever to make nori-wrapped onigiri for consumption. This invention aims to solve the problem by improving the extrusion so that it can be easily pulled out when pulling out the drawing material, making it possible to make seaweed-wrapped rice balls without touching them directly, and to be able to eat them as they are. There is a problem to be solved.

[Means to solve the problem]

The present invention was developed in order to solve the above-mentioned problems, and is a rice ball packaging in which the center of one side of a bag formed into an approximately rectangular shape is cut off, and a strip-shaped peel-off sticker is provided at the center of the other side. and a pull-out material that covers either the front side or the back side of the cut surface of the rice ball packaging material and is formed in a triangular shape so as to be able to be pulled out from the rice ball packaging material, the bag of the rice ball packaging material A rice ball packaging device body is constructed by inserting seaweed shaped into a desired shape into the body, a rice ball is packaged in the rice ball packaging device body, and when eaten, the peel-off seal is peeled off and the pull-out material is pulled out, thereby forming the rice ball. The present invention provides a seaweed-wrapped rice ball packaging device characterized by forming a seaweed-wrapped rice ball inside the packaging material, the drawing material may be diamond-shaped, and the rice ball packaging material and the drawing material may be made of transparent or translucent synthetic resin. It is even better if it is made of a film material, and one or both sides of the drawing material are made of a material that has low resistance and is easy to slip.

In addition, the rice ball packaging material and the drawing material are mainly made of thermoplastic resin and antibacterial zeolite, and the antibacterial material contains the antibacterial zeolite in a range of 0.1 to 5% by weight based on the total weight of the thermoplastic resin. Even better if it is configured.

Furthermore, the rice ball packaging material and the drawing material mainly consist of a thermoplastic resin and an antibacterial zeolite, and the antibacterial zeolite is in a range of 0.1 to 5% by weight based on the total weight of the thermoplastic resin, and
It may be formed from a multilayer sheet in which at least one thermoplastic resin sheet is fused or adhered to a sheet having a thickness of 0.03 mm to 0.1 mm.

[Effect]

(1) According to the packaging device for nori-wrapped rice balls having the above-mentioned configuration,
When eating, the peel seal is peeled off and the corners of the triangular pull-out member are grasped and pulled out by hand to make the nori-wrapped rice ball inside the rice ball packaging material, so that the rice ball packaging material can be easily opened and the nori-wrapped rice ball can be made with a single touch.

(2) Furthermore, if the drawn material is made into a diamond shape, the corners of the diamond shape can be grabbed and pulled out by hand, so the drawn material can be easily pulled out when eating.

(3) The rice ball packaging material and the drawn material are made of transparent or translucent synthetic resin film material, and one or both sides of the drawn material are made of a material that has low resistance and is easy to slip. You can see the packaging condition of the rice ball, and in addition, the resistance between the rice ball packaging material and the pulling material is reduced, so there is no need to add oil components such as dressing to the rice ball rice.
A pull-out material can be easily pulled out from a packaged seaweed-wrapped rice ball packaging material.

(4) The rice ball packaging material and the drawing material are made of antibacterial material, and the antibacterial material is 0.03mm thick.
Even if the rice ball packaging material and the drawing material are made of a multilayer sheet made by fusing or gluing at least one thermoplastic resin sheet to a sheet with a thickness of ~0.1 mm, the packaging material may become sterile, resulting in the packaging being damaged. It is possible to prevent bacteria from accumulating or rotting onigiri rice or seaweed-wrapped rice balls.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

FIGS. 1 to 3 show a seaweed-wrapped rice ball packaging device of the present invention, which has substantially the same structure as the embodiment shown in FIGS. 7 to 9. 1 is the main body of the rice ball packaging device. The rice ball packaging main body 1 includes a rice ball packaging material 2, a pull-out material 7, and a sheet of seaweed S.
It is composed of. The difference between the seaweed-wrapped rice ball packaging device of the present invention and the seaweed-wrapped rice ball packaging device shown in FIGS. 7 to 9 is that the shape of the pull-out material 7 shown in FIGS. 7 and 8 is different.

In other words, the shape of the drawn material 7 is 2 with an acute angle between them.
It is an equilateral triangle. By forming the drawn material 7 in this way, the acute angle portion 7a of the drawn material 7 is
It is placed on the rice ball packaging material 2 so as to protrude from the long side of the rice ball packaging material 2. Also, the drawn material 7 having an acute isosceles triangle shape is shown in Fig. 2 A and Fig. 2
As shown in Figure B, either the top or bottom of the back surface portion 6 is coated, and substantially the same effect can be obtained. The rest of the structure is similar to the embodiment shown in FIGS. 7 to 9, so reference numerals are attached to the drawings and explanation thereof will be omitted.

Next, the state of use of the present invention will be explained using A, B, C, and H of FIGS. 3 and 9.

First, the desired seaweed-filled rice ball packaging tool body 1
Prepare a triangular rice ball W, and place the rice ball W on either side of the back side 6 of the rice ball packaging material 2.
, fold both sides of the back part 6 as shown in Figure A, and then overlap and seal the folded parts 8 on both sides to form a packaged rice ball H as shown in Figure B. At that time, remove the onigiri packaging material 2 so that the peel-off sticker 3 on the onigiri packaging material 2 can be removed by pinching it with your fingers.
It is made to protrude somewhat from the long side of the
The acute-angled part 7a of the acute isosceles triangular drawing material 7 is also designed to protrude somewhat from the long side of the rice ball packaging material 2 so that it can be pulled out by pinching it with fingers.

Next, when eating the rice ball, peel off the peel-off sticker 3 in the state shown in Figure C to open the approximately central part of the rice ball packaging material 2, and then pull out the pull-out material 7 from the side as shown in Figure 3. Since the drawing material 7 has an acute isosceles triangle shape, the drawing material 7 does not wrinkle and become difficult to pull out as in the case of FIG. 9D, and can be smoothly removed from the rice ball packaging material 2. The seaweed-wrapped rice ball M as shown in Fig. E is completed. Then, the rice ball wrapping material 2 can be peeled downward while being sealed by the seal 9, or it can be eaten while pushing up the seaweed-wrapped rice ball M by hand. In other words, if you use the rice ball packaging tool of the present invention, you can make crunchy seaweed-wrapped rice balls just by peeling it off and pulling it out.

FIG. 4 shows another embodiment of the present invention,
The difference from the embodiment shown in FIGS. 1 to 3 is that the drawn material 7 is formed in a diamond shape. Other configurations and operations are similar to those of the embodiment shown in FIGS. 1 to 3, so reference numerals are attached to the drawings and explanation thereof will be omitted.

Next, the material of the rice ball packaging device according to the present invention will be explained with reference to FIG. The rice ball packaging main body 1 is formed from a packaging sheet, and in particular, a sterile packaging sheet is used.

The antibacterial material of this packaging sheet 21 mainly consists of a thermoplastic resin 22 and an antibacterial zeolite 23, and the antibacterial zeolite 23 is in the range of 0.1 to 5% by weight based on the total weight of the thermoplastic resin 22.

This thermoplastic resin 22 can be mixed with the antibacterial zeolite 23, and has the characteristics required as a packaging sheet for food and drink, such as being able to withstand a certain degree of low and high temperatures, and heat retention and cold retention. Any material may be used as long as it has a certain degree of elasticity, does not give off an odor to food, is water resistant, and is non-toxic.

The thermoplastic resin 22 includes polyethylene, polystyrene, ABS resin, acrylic styrene, polypropylene, ethylene vinyl copolymer, polyvinyl chloride,
Any thermoplastic resin can be used, such as methacrylic, polyamide (nylon), polycarbonate, polyethylene terephthalate, polymethylpentene, fluororesin, polysulfone, oxybenzoyl polyester, and polybutene.
In addition, from the viewpoint of workability, it is preferable to use a material that becomes plastic at a relatively low temperature. However, depending on the intended use, it may be better to use a material that becomes plastic at a high temperature.

The antibacterial zeolite 23 may have antibacterial metal ions, such as silver, copper, zinc, etc., substituted for some or all of the ion-exchangeable ions of natural zeolite or synthetic zeolite (Japanese Patent Laid-Open No. 1986-60). -Refer to Publication No. 181002).

That is, zeolites are generally aluminosilicates with a three-dimensional skeleton structure, and the general formula is
It is expressed as XM ² / _o O・Al ₂ O ₃・YSiO ₂・ZH ₂ O.
Here, M represents an ion exchangeable ion, which is usually a monovalent or divalent metal ion, such as sodium, potassium, magnesium, iron, etc., n is the valence of the metal ion, and X is a metal oxide. Y is the coefficient of silica, and Z is the number of crystal water molecules. Such a general formula XM ² / _o O・
The ion exchange capacity of the zeolite represented by Al ₂ O ₃ .YSiO ₂ .ZH ₂ O is 2.6 ^meq / _g to 11.5 ^meq / _g . Therefore, in the antibacterial zeolite 23, the ion-exchangeable ions are replaced with antibacterial metal ions such as silver, copper, and zinc. From the viewpoint of antibacterial properties, the antibacterial zeolite 23 preferably contains about 0.1 to 15% by weight of these antibacterial metal ions (expressed in weight% on a dry basis at 110° C.).

Moreover, this antibacterial zeolite 23 may be a natural zeolite or a synthetic zeolite in which part or all of the ion-exchangeable ions are replaced with ammonium ions and antibacterial metal ions (Japanese Patent Application No. 61-290144). (See "Antibacterial Zeolite" filed on December 4, 1988, claiming priority under Article 42-2, Paragraph 1 of the Patent Law). The reason for adding ammonium ions in this way is to effectively prevent discoloration of the antibacterial zeolite 23, and the ammonium ions in this antibacterial zeolite 23 are 0.5
A content in the range of ~2.0% by weight is preferable. Furthermore, from the viewpoint of substantially preventing discoloration of the thermoplastic resin 22, it is preferable that the content of the antibacterial zeolite 23 containing ammonium ions is 0.1 to 3.0% with respect to the thermoplastic resin 22. .

The antibacterial properties, sustainability of antibacterial activity, heat resistance, and safety of these two types of antibacterial zeolites 23 are described in detail in these publications or application examples.

The packaging sheet 21 as described above is mainly composed of a thermoplastic resin 22 and an antibacterial zeolite 23, as shown in FIG.
Antibacterial zeolite 23 is 0.1% of the total weight of 2.
~5% by weight, and 0.03mm ~ 0.1mm
It may be a multilayer sheet 26 in which at least one thermoplastic resin sheet 25 is fused or adhered to a thick sheet 24. In this way, the multilayer sheet 26
The reason for using zeolite is that it is sufficient to impart antibacterial properties to one side of the multilayer sheet 26, and the amount of antibacterial zeolite 23 used can be reduced to reduce costs.

[Effect of idea]

Since the present invention is configured as described above, when eating a seaweed-wrapped rice ball, the peel-off sticker of the rice ball packaging material can be peeled off and the end of the pull-out material, which is shaped to be easily pulled out, can be easily grasped. Moreover, since it has a shape that is easy to pull out, it is possible to easily pull out the material by pulling it in the horizontal direction, making it possible to make crispy seaweed-wrapped rice balls. Moreover, you can eat it without touching it directly.
Not only is it more convenient than the conventional method, but it is also highly effective in terms of hygiene.

In addition, since the rice ball packaging device of the present invention is made of sterile material, there is no possibility that germs will adhere to the packaged rice for the rice balls or the seaweed for the nori rolls, and the rice balls wrapped in the nori seaweed can be prepared for consumption. Bacteria will not be attached even when it gets wet. As a result, the shelf life of the seaweed-wrapped rice balls is increased, which also helps prevent food poisoning and the like.
