As this thermal balloon, the opening part of the paper bag-like balloon body is faced downward, a ring-shaped frame body is provided in the opening part, and the opening state is maintained. (For example, refer to Patent Document 1), the heated air heated by the heating unit is taken into the bag-like balloon body and floats.

  In the above hot balloons, Japanese paper is generally used as the paper for forming the bag-shaped balloon body, and the ring-shaped frame that holds the opening of the bag-shaped balloon body in an open state is a bamboo basket or wire. Further, a wire is used as an attachment member for attaching the heating part to the frame so that it is positioned at the center of the opening.

Japanese Patent Laid-Open No. 2001-247094

  In the above hot balloons, Japanese paper is generally used as the paper that forms the bag-shaped balloon body, but Japanese paper is strong in water and does not disperse easily in water, for example, when a hot balloon falls into a lake or ocean In addition, since cellulose, which is a constituent of Japanese paper, takes a long time to decompose naturally, there has been a problem in that the bag-like balloon body floats on the water or in the water and affects aquatic organisms.

Also, since the wire is used for the ring-shaped frame that holds the opening of the bag-like balloon body in the open state and the attachment member that attaches the heating unit to the frame, the frame of the wire that has fallen into the lake or the ocean In addition, there is a problem that the attachment member may be caught in the aquaculture net or the fishery net and damage the net or the net. Also, when bamboo frames are used for the frame, bamboo is a natural product and decomposes in nature, but its degradation rate is slow and hard, so when bamboo falls into the ocean, Similarly, there is a problem that the net or the net may be damaged.
For this reason, it was necessary to consider the recovery of hot balloons that fell into lakes and oceans.

  It is an object of the present invention to provide a hot balloon that can prevent pollution of the natural environment and does not need to be recovered after flying.

  In order to achieve the above object, according to the first aspect of the present invention, the opening of the paper bag-like balloon body is directed downward, and a ring-shaped frame is provided at the opening end to maintain the opening state. In this frame body, a heating balloon is located at the center of the opening and a heating part is attached via an attachment member, and the bag-like balloon body is formed of water-decomposable or water-soluble paper, The frame is formed of a paper shaft using water-decomposable or water-soluble paper, and the attachment member is formed of non-combustible yarn or non-combustible paper twist.

  The invention according to claim 2 is characterized in that the water-decomposable or water-soluble paper according to claim 1 has a water dispersibility within 100 seconds, which is defined by JIS P450. And

  The invention described in claim 3 is characterized in that the water-decomposable or water-soluble paper forming the bag-like balloon body according to claim 1 or 2 is a water-soluble laminated paper.

  A fourth aspect of the present invention is characterized in that the heating unit according to any one of the first to third aspects uses wax as a fuel.

According to the hot balloon of claim 1, since the bag-like balloon body is formed of water-decomposable or water-soluble paper, the bag-like balloon body can be removed in a short time when falling to a lake or the ocean. Since the frame is formed of a paper shaft using water-decomposable or water-soluble paper, the frame is formed in a short time, similar to the bag-like balloon body. Since it is undissolved or melts and disperses in water, the bag-shaped balloon body can be prevented from polluting the natural environment due to floating on the water for a long time, and the frame body also melts and disperses in water. There is no problem of damaging nets and nets laid underwater such as frames made of bamboo and bamboo.
In addition, since the attachment member is formed of a non-combustible yarn or a non-combustible paper twist, even if it is caught in a net or a net laid in the water, it is laid in the water like a conventional wire-made attachment member There is no problem of damaging the network or the network.

  According to the hot balloon according to claim 2, the water-decomposable or water-soluble paper according to claim 1 has water dispersibility within 100 seconds, which is defined by JIS P450. So, when falling into a lake or ocean, the bag-like balloon body and the frame will melt and disperse in a short time without almost floating on the water or in the water, preventing pollution of the natural environment more effectively it can.

  According to the hot balloon according to claim 3, the water-decomposable or water-soluble paper forming the bag-like balloon body according to claim 1 or 2 is a water-soluble laminated paper, and thus has good airtightness. When heated air is taken into the bag-shaped balloon body, it becomes easy to float, so it is possible to reduce the basis weight of the paper forming the bag-shaped balloon body, and the bag-shaped balloon body can be reduced in weight. The part can be reduced in size and fuel can be saved.

  According to the hot balloon described in claim 4, since the heating unit according to any one of claims 1 to 3 uses wax as fuel, even if the wax falls into a lake or the ocean without burning. There is no problem of wax biodegrading and polluting lakes and oceans.

It is a perspective view which shows an example of embodiment of the hot balloon which concerns on this invention. It is a top view of the ring-shaped frame shown in FIG. It is a perspective view of the heating part attached to the frame shown in FIG. 1, and the attachment member which attaches a heating part to a frame.

Hereinafter, an example of an embodiment of a hot balloon according to the present invention will be described with reference to the drawings.
1 is a perspective view of this example, FIG. 2 is a plan view of the ring-shaped frame shown in FIG. 1, and FIG. 3 is a heating unit attached to the frame shown in FIG. 1, and an attachment member for attaching the heating unit to the frame FIG.
The hot balloon of the present example has the opening 2 of the paper bag-shaped balloon body 1 facing downward, and the opening end 3 is provided with a ring-shaped frame 4 so that the open state is maintained. A heating unit 6 is attached to the frame body 4 via an attachment member 5 located at the center of the opening 2.

The bag-shaped balloon body 1 is formed of water-decomposable or water-soluble paper. As the water-decomposable paper, it is desirable that the paper has water dispersibility within 100 seconds, which is easy to solve as defined in JIS P450. Further, as the water-soluble paper, paper having water dispersibility within 60 seconds and more desirably water dispersibility within 20 seconds is desirable in the following water dispersibility test.
(Water dispersibility test)
Five 3 cm square test pieces were prepared from a sample harmonized for 24 hours or more in an atmosphere of 23 ° C. and 50% RH. Next, 300 ml of deionized water was placed in a 300 ml beaker, and one of the above test pieces was added while stirring at 650 rpm with a stirrer. The time when the test piece was cut into two or more pieces was determined with a stopwatch, and the average value of the five measurements was taken as the water dispersion time.
An example of water-degradable paper is CSD22 (manufactured by Nippon Paper Papillia), and an example of water-soluble paper is 30MDP (manufactured by Nippon Paper Papillia).

The basis weight of the paper may be appropriately selected depending on the size of the bag-like balloon body 1 and the like, but is preferably 10 g / m ² or more and 70 g / m ² or less, more preferably 15 g / m ² to 35 g / m ^2. Range. If it is 10 g / m ² or less, the airtightness of the paper is impaired, and the bag-like balloon body 1 is unlikely to rise. If it is 70 g / m ² or less, the paper is heavy, the weight of the bag-like balloon body 1 is increased, and it is difficult to rise.

  Furthermore, in order to improve the air tightness of the bag-shaped balloon body 1, that is, the paper air tightness, it is particularly preferable that the water-decomposable or water-soluble paper is a water-soluble laminated paper. Examples of the water-soluble laminated paper include Dissolvo (registered trademark) A3015 in which water-soluble polyvinyl alcohol is laminated on water-soluble paper.

  The shape of the bag-shaped balloon main body 1 is not particularly limited, and is configured as, for example, a cylindrical shape or a rectangular tube shape in which the upper portion is sealed and the lower portion is opened like a conventional hot balloon. In addition, water-soluble paste such as starch paste and polyvinyl alcohol paste is used as the paste used to form the bag-shaped balloon body 1.

The frame 4 is formed by a paper shaft 7 using water-decomposable or water-soluble paper. The water-decomposable or water-soluble paper used for the paper shaft 7 is preferably water-decomposable or water-soluble paper that forms the bag-shaped balloon body 1 described above. The paper shaft 7 is made by a conventional method, and is made by tightly winding water-decomposable or water-soluble paper and solidifying with starch paste so as not to be unwound.
Both ends of the paper shaft 7 are inserted and connected from both sides of a paper connecting tube 8 to form a ring-shaped frame 4. In this example, as shown in FIG. 2, a plurality of paper shafts 7 are prepared by dividing the peripheral length of the opening of the bag-shaped balloon body 1, and these are connected by a connecting pipe 8 to form a ring-shaped frame. 4 is formed (FIG. 2). The connecting tube 8 is also preferably made of water-decomposable or water-soluble paper.
The frame body 4 formed in this way is attached to the open end 3 of the bag-like balloon body 1 with water-soluble glue such as starch paste or polyvinyl alcohol glue.

The attachment member 5 for attaching the heating unit 6 to the frame body 4 is formed of non-combustible yarn or non-combustible paper twist.
As a material for the non-combustible yarn, for example, a PAN-based flame resistant fiber obtained by oxidizing polyacrylonitrile (PAN) fiber at 200 to 300 ° C. in air (Pyromex (registered trademark) manufactured by Toho Tenax Co., Ltd., Lastan (registered trademark) Asahi Kasei Co., Ltd. Organic fiber or inorganic fiber with LOI (Limited Oxygen Index) value of 50 or more such as glass fiber, polyparaphenylene benzoxazole fiber (Zylon (registered trademark) Toyobo Co., Ltd.), fluorine fiber, etc. Can be illustrated.
For nonflammable paper twist, flame retardant paper in which paper is impregnated with a flame retardant is used. Examples of the flame retardant include a phosphorus flame retardant, a halogen flame retardant, and a metal hydroxide flame retardant. The nonflammable paper twist may be coated with starch paste to obtain strength. It is preferable to use water-decomposable or water-soluble paper as the nonflammable paper twist.

In the heating unit 6 attached to the frame body 4 by the attachment member 5, in this example, a paper core member 9 is impregnated with fuel. The paper core member 9 is preferably a thin paper roll wound from the viewpoint of fuel impregnation. For example, a toilet paper roll can be used as a roll of thin paper.
Also, wax is used as the fuel. As the wax, paraffin wax, beeswax, wood wax obtained from the fruits of the tree, etc. are preferably used.
As shown in FIG. 3, the heating unit 6 is bound by an attachment member 5 and fixed to the frame body 4 from four directions.

  According to the hot balloon configured as described above, the bag-shaped balloon main body 1 is formed of water-decomposable or water-soluble paper. In particular, if the water-degradable paper has a water-dispersibility within 100 seconds specified by JIS P450, it can be unwound in a shorter time and water-dispersed. If the paper has water dispersibility within 60 seconds in the water dispersibility test, and further has water dispersibility within 20 seconds, the paper melts and disperses in a shorter time.

  In addition, if the water-decomposable or water-soluble paper forming the bag-shaped balloon body 1 is a water-soluble laminated paper, the bag-shaped balloon body will be easy to float when heated air is taken into the bag-shaped balloon body. The basis weight of the paper forming 1 can be reduced, and the weight of the bag-like balloon body 1 can be reduced.

  Further, since the frame body 4 is formed by the paper shaft 7 using water-decomposable or water-soluble paper, it is dispersed in a short time in the same manner as the bag-like balloon body 1. In this example, a plurality of paper shafts 7 are prepared by dividing the peripheral length of the opening of the bag-shaped balloon main body 1, and these are connected by a connecting pipe 8 to form a ring-shaped frame 4. In the case of falling into a lake or ocean, the paper shaft 7 is disassembled at the portion connected by the connecting pipe 8, the paper shaft 7 connected is separated, and the length of the paper shaft 7 is shortened. Therefore, water dispersion becomes slow, and even if it catches on a net or net in the water, the influence on fisheries etc. can be reduced.

In addition, the attachment member 5 for attaching the heating unit 6 to the frame body 4 is formed of non-combustible yarn or non-combustible paper twist, so when it falls into a lake or ocean, it catches on a net or a fishing net. Even so, there is no risk of damaging the net or net unlike conventional wires.
In addition, since the heating unit 6 uses wax as fuel, even if the wax does not burn and falls to the lake or the ocean, the wax biodegrades and does not pollute the lake or the ocean.

Examples of the present invention and comparative examples are given below to illustrate the features of the present invention. This invention is not restrict | limited at all by an Example and a comparative example.
