Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper balloon, and more particularly to a paper balloon made of natural cellulose fiber paper which can be continuously flown in the air and can be rapidly decomposed after dropping without damaging the natural environment. .

[0002]

[Prior Art] At the completion ceremony of various facilities, at various events and commemorative events, etc., helium gas is enclosed in a rubber balloon made of a rubber bag and thrown in the air as a production to enliven the atmosphere of the ceremony. I am letting you. A large number of rubber balloons soaring in the sky impresses the viewer and gives a visual effect. It is estimated that the amount of rubber balloons consumed each year will reach tens of millions.
Further, even in amusement parks and the like, rubber balloons containing helium gas or the like are popular with children.

On the other hand, conventional paper balloons are used only for decoration in the room or for playing games by pushing them up with a hand, and there is no one for continuously flying in the air.

However, since the rubber balloon loses its buoyancy and does not decompose after falling to the ground, it certainly destroys the natural environment, and birds and animals may accidentally prey on it. For this reason, recently, from the perspective of protecting the global environment, regardless of whether it is public or private, we are currently refraining from blowing rubber balloons at various events.

[0005]

Therefore, even if a paper balloon is blown instead of a rubber balloon, in order to continuously fly the paper balloon in the air, the enclosed inert gas does not leak and the airtightness is high. Therefore, it is required to satisfy both of light weight and buoyancy at a high level at the same time. On the other hand, the conventional light weight paper, as it is, lacks airtightness for enclosing the inert gas. Therefore, if the conventional lightweight paper is used, the paper itself needs to be laminated with a film or impregnated with an oil agent or a high molecular polymer as a measure for preventing gas leakage, and the weight becomes heavier. When the weight becomes heavy, it is limited to a large volume paper balloon in order to obtain buoyancy capable of flying. Above all, the above processing makes it impossible to disassemble after dropping, and there is no point in using paper balloons.

On the other hand, if thick heavy paper is used, the gas leakage can be reduced to a certain extent and the degree of gas leakage can be reduced. Will be limited to. Therefore, it has not been possible to manufacture a paper balloon capable of continuously flying in the air, which can replace the rubber balloon, by the conventional technique.

In view of the above circumstances, the present invention provides a paper balloon made of natural cellulose fiber paper, which can be continuously flown in the air and can be quickly decomposed after dropping without damaging the natural environment. The purpose is to

[0008]

In order to achieve the above-mentioned object, the present invention is a paper balloon of a predetermined shape formed of highly airtight natural cellulose fiber paper, which is fixed by enclosing an inert gas. Providing paper balloons that can fly in the air for continuous hours. The natural cellulose fiber paper has a structure in which the air permeability is 10,000 seconds / 100 cc or more, and the natural cellulose pulp is made into a standard Canadian standard type water degree of 0 c.
(c) A composition obtained by papermaking the raw material beaten below is provided.

[0009]

According to the present invention having the above-mentioned structure, the buoyancy capable of flying in the air can be maintained and the buoyancy can be maintained for a certain period of time. Can fly in the air. Moreover, it has a degradability in water that can be rapidly decomposed without damaging the natural environment after dropping.

EXAMPLES The constitution of the present invention will be described below together with various examples. The paper balloon according to the present invention is formed of highly airtight natural cellulose fiber paper. Highly airtight natural cellulose fiber paper is made of coniferous wood, hardwood wood pulp fiber, Manila hemp, red hemp, sisal, cotton and other non-wood pulp fibers. : Canadian Standard
The raw material is beaten with a beater, refiner or other known beating machine so that the numerical value of rd Freeness is 0 cc or less. The reason that the CSF value is beaten to 0 cc or less is to increase the denseness and the airtightness. Then, the raw material was made into paper by a Fourdrinier paper machine, a former, etc., and the air permeability value in JIS P8117 "Paper and board air permeability test method" was at least 10,000 seconds / 10.
A natural cellulose fiber paper of 0 cc or more is obtained. It is necessary for the value of this air permeability to be at least 10,000 seconds / 100 cc or more in order to fly in the air continuously for a certain period of time. Further, a natural cellulose fiber paper having a basis weight of not more than 50 g / m ² is preferable. When the basis weight exceeds 50 g / m ² , the weight of the paper balloon itself becomes large, a large amount of inert gas is required to fly in the air, and the volume of the paper balloon becomes too large.

From this high airtight natural cellulose fiber paper, a paper balloon having a desired predetermined shape is manufactured. That is, after cutting this natural cellulose fiber paper into a spherical, triangular pyramid (tetrahedron), cone, cylinder, or other free-form development view, a water-soluble glue or water-soluble adhesive such as starch paste or CMC (carboxymethylcellulose) is cut. A paper balloon is manufactured by bonding with an adhesive such as tape. Therefore, it is advisable to form the glue margin portion in advance when cutting the development view.

In order to fill the inert gas, a part of the paper balloon may be opened and sealed after the inert gas is filled. However, a separate paper valve as described below should be manufactured and used. Is preferred. That is, two rectangular natural cellulose fiber papers having a width of 1 to 5 cm and a length of 5 to 20 cm are superposed,
A separate valve is manufactured by laminating both ends in the longitudinal direction. Then, a hole is formed at an appropriate position on the side surface of the paper balloon, and the paper valve is inserted so that one end of the paper valve remains outside the paper balloon, and the paper valve is attached integrally with the hole. To seal the inert gas, seal the inert gas in the opening of the paper valve through a straw, etc., and then bend and stick the paper valve or bond it with a paper string to ensure airtightness. Retained. Also, the enclosed gas can be replenished at any time.

Further, when cutting the natural cellulose fiber paper into a developed view of a paper balloon, a rectangular extra portion is left in advance at a position corresponding to one end of the paper balloon, and the end is attached to the paper balloon. A cutoff valve may be used, which may be bent and pasted after being filled with an inert gas, or may be bound with a paper string.

The inert gas used may be helium, neon, argon or the like, but helium gas is preferred because of its price and availability.

It should be noted that natural cellulose fiber paper is preprinted, or when it is cut into a development view or after being attached to a paper balloon, it is further colored as a paper balloon by coloring or painting with a color spray or a paintbrush. It is possible to increase the value. In particular, children can color and paint by themselves, so they can get their own unique paper balloons in the world. You can also freely display the message on the paper balloon itself.

According to the paper balloon of the present invention described above, since it has a buoyancy capable of continuously flying in the air by enclosing an inert gas and a high airtightness for maintaining the buoyancy, it is replaced with a rubber balloon. You can make paper balloons fly to the sky. Further, it is possible to play by holding a paper string on the lower end of the paper balloon and holding it with a human hand. And
Since it is formed from natural cellulose fiber paper after flight, it is easily decomposed after a certain period of time, so that it does not adversely affect the natural environment.

Specific examples will be described below.
The evaluation of the examples was performed by the following measuring method and device. Basis weight: Measured by a metric basis weight measuring method of paper according to JIS P8124. Air permeability: Measured by the air permeability test method of JIS P8117 paper and paperboard. CSF (unit: cc): JIS P8121 pulp water content test method 2.1 Measured according to Canadian Standard Form. How to measure the buoyancy of a paper balloon and the connection time of the buoyancy: Place a plastic washing bottle with a weight of about 300 g on the electronic balance to zero the scale, then fill the paper balloon with helium gas, and attach the paper balloon and the tip of the washing bottle to a tree. Connected with a cotton thread, the scale of the electronic balance was read (-display) and used as the buoyancy (g). Also, the time until the buoyancy becomes zero (time to levitate in the air)
Is the duration of buoyancy. Underwater degradability test: 10 cm square natural cellulose fiber paper was put into a 1 liter beaker containing 300 cc of water,
The rotational speed of the magnetic stirrer was set to 500 rpm and stirring was performed, and the time (minute) until the sample became 2 mm square or less, that is, the rotational speed returned to 500 rpm was measured.

First, in order to select the lightweight and highly airtight natural cellulose fiber paper used in the present invention, softwood kraft pulp and Manila hemp pulp are each subjected to C in a refiner.
Beat to SF0cc, and use a Fourdrinier paper machine to weigh 15,2.
5,35,45 g / m ² of natural cellulose fiber paper was made, and the minimum capacity and in-water degradability test of flyable paper balloons for each basis weight were conducted. The results are shown in Tables 1 and 2.

[0019]

[Table 1]

As shown in Table 1, spherical and regular tetrahedral paper balloons were manufactured using natural cellulose fiber papers having different basis weights, filled with helium gas, and buoyancy was measured.
In each case, buoyancy was generated, and it was possible to find the minimum volume that could fly into the air. For example, in the case of a spherical paper balloon having a diameter of 9 cm, the buoyancy was 0.05 g, and when the diameter was 19 cm, the buoyancy increased to 0.38 g. In the case of a regular tetrahedron, the buoyancy was 0.01 g when the length of one side was 33 cm, and the buoyancy increased to 0.35 g when the length of one side was 60 cm. Therefore, if the diameter is about 9 cm in the case of a spherical shape and the length of one side is about 33 cm in the case of a regular tetrahedron, buoyancy capable of flying can be obtained. On the other hand, when the basis weight exceeds 50 g / m ² , the diameter is 30 cm or more for a spherical shape and the side length is 70 cm or more for a regular tetrahedron. For the purpose of flying freely in the air, There is a cost hindrance. Therefore, the basis weight of the natural cellulose fiber paper used in the present invention is preferably 50 g / m ² or less. The capacity can be increased, and in that case, the basis weight is not limited and a basis weight of 50 g / m ² or more may be used. For example, there is no limit to the capacity when flying fixedly in the air such as an ad balloon.

[0021]

[Table 2]

As shown in Table 2, the natural cellulose fiber paper of the present invention having a basis weight of 15.4 g / m ² has a degradability in water of 6 minutes, which is 6/12 times that of commercially available tissue paper. Has degradability in water. The basis weight is 45.3 g /
It is 38 minutes even for m ² and it can be seen that it has excellent water degradability even compared to 135 minutes for newspaper.

Therefore, Manila hemp pulp and coniferous wood pulp are beaten to CSF0cc by a refiner, and a lightweight and highly airtight natural cellulose fiber paper having a predetermined basis weight and air permeability is made by a Fourdrinier paper machine. Then, the development view of the regular tetrahedron was pasted with starch paste to manufacture a regular tetrahedral paper balloon. Then, a separate paper valve having a width of 2 cm and a length of 10 cm made of a natural cellulose fiber paper made of a softwood lumber kraft pulp having a basis weight of 45.3 g / m ² was inserted by inserting one end of the paper balloon into a hole. After sticking with starch paste, a predetermined amount of helium gas was enclosed, and a paper valve was bound with a paper string having a diameter of 1.5 mm and a length of 1 m, and the buoyancy and the duration of buoyancy were measured. As a comparative example, softwood kraft pulp is CSF.
Using a natural cellulose fiber paper beaten to 100 cc, a paper balloon similar to that in the example was manufactured and the same measurement was performed. The results are shown in Table 3.

[0024]

[Table 3]

As shown in Table 3, it is understood that all of Examples 1 to 7 have sufficient buoyancy capable of flying in the air and buoyancy sustainability. For example, Example 1 having an air permeability of 54400 seconds / 100 cc has a buoyancy duration of 3 hours, and Example 4 having the highest air permeability has an air permeability of 367,000 seconds / 100 cc.
It has an air permeability of 18 hours and a duration of 18 hours. Also, 133
It has a sufficient duration of 1.5 hours in Example 7 of 00 seconds / 100 cc. On the other hand, air permeability is 10,000 seconds / 100c
In the comparative example of 3720 seconds / 100 cc which is less than or equal to c, it is 8.
It has a buoyancy of 8g, but its duration is only 16 minutes, which is not enough for continuous flight in the air, which is not practical. Therefore, the air permeability is 10,000 seconds / 100
It is preferably cc or more.

[0026]

As described above in detail, the paper balloon formed in a predetermined shape from the highly airtight natural cellulose fiber paper has the buoyancy capable of flying in the air by enclosing the inert gas, and the buoyancy can be maintained for a certain time. Since it can be sustained, even a paper balloon formed of natural cellulose fiber paper can continuously fly in the air for a certain time. Moreover, after dropping, it can be quickly decomposed without destroying the natural environment. Therefore, it can be replaced with the conventional rubber balloons that are self-restrained, and can be moved up to the sky in various memorial ceremonies, etc., to give the viewer an impression and a visual effect. Therefore, it has great industrial value and can be used as educational materials for protecting the global environment. Further, the shape thereof can be arbitrarily formed, and even when compared with a rubber balloon, a creative shape can be obtained. Therefore, it is possible to provide paper balloons of various three-dimensional shapes that could not be manufactured with rubber balloons, instead of the rubber balloons of characters sold in amusement parks and the like.
Further, since it is made of paper, it is possible to freely enjoy coloring and painting.
