を阻止している。Next, the housing case body 2 is assembled into inner and outer parts with the non-woven fabric.
A bag-shaped bag with a heavy structure is used, and the inner layer 2
A shielding layer 21 is formed between A and the outer layer 2B to prevent the citric acid in the oxygen generating agent 3 from leaching out of the case body in the liquid.

水素イオン濃度（ｐＨ）が低下するのを抑制している。This shielding layer 21 is formed by applying a neutralizing agent (or adsorbent) to the surface of the nonwoven fabric during the manufacturing stage of the housing case body 2, and prevents the citric acid in the oxygen generating agent 3 from leaching out of the case body. By neutralizing this, a decrease in the hydrogen ion concentration (pH) in the liquid is suppressed.

換樹脂等が使用される。As this neutralizing agent, a salt of a strong base and a weak acid is used, which exhibits weak alkalinity when dissolved in water, and is harmful even if it reacts with the acid (for example, citric acid) in the oxygen generating agent 3. For example, inorganic bases such as sodium bicarbonate, sodium carbonate, and sodium acetate, organic bases such as chitosan, and other ion exchange resins are used.
さらに図示例の酸素発生部材１においては、収容ケース
体２の外周面全体に高収縮性ビニロン糸４が適当ピッチ
で巻き付けである。Furthermore, in the illustrated oxygen generating member 1, highly contractile vinylon thread 4 is wound around the entire outer peripheral surface of the housing case body 2 at an appropriate pitch.
この高収縮ビニロン糸４は、湿潤時に収縮する性質を有
するものであって、この酸素発生部材１を水中へ投入し
た際に高収縮ビニロン糸４を収縮させることによって、
収容ケース体２内の空気を外部へ押し出して酸素発生剤
３０粒子を密着させ、これにより反応速度を適宜に調節
すると共に、酸素発生部材の浮上がりを防止している。This high shrinkage vinylon thread 4 has the property of shrinking when wet, and by shrinking the high shrinkage vinylon thread 4 when this oxygen generating member 1 is put into water,
The air inside the storage case body 2 is pushed out to the outside to bring the oxygen generating agent 30 particles into close contact with each other, thereby appropriately adjusting the reaction rate and preventing the oxygen generating member from floating up.
なお上記は収容ケース体２に高収縮ビニロン糸４を巻き
つけることで内部の充填物を締め付けているが、これに
限らず、例えば収容ケース体２自体を高収縮ビニロン繊
維をもって形成すれば、収容ケース体への糸の巻きつけ
る作業が不要となり、作業の能率が向上する。In the above example, the internal filling material is tightened by wrapping the high shrinkage vinylon thread 4 around the accommodation case body 2. However, the present invention is not limited to this. For example, if the accommodation case body 2 itself is made of high shrinkage vinylon fiber, the accommodation There is no need to wind the thread around the case body, improving work efficiency.
上記構成の酸素発生部材１を製作するには、まず収容ケ
ース体２を作るための一枚の不織布を用意し、この不織
布の半分に中和剤を塗布する。つぎに中和剤を塗布して

さらに中和剤を塗布した他の半分をその上に巻いて外層
２Ｂを形成する。そして不織布の端部を必要に応じて接
着すると、内層２人と外層２Ｂとの間に中和剤による遮
蔽層２１を備えた内外２重構造の筒状体が形成される。To manufacture the oxygen generating member 1 having the above configuration, first, a piece of nonwoven fabric for making the housing case body 2 is prepared, and a neutralizing agent is applied to half of this nonwoven fabric. Next, half of the nonwoven fabric that has not been coated with a neutralizer is wrapped in a single layer to form an inner N2A.
Further, the other half coated with a neutralizing agent is wound thereon to form an outer layer 2B. Then, by adhering the ends of the nonwoven fabric as necessary, a cylindrical body with an inner and outer double structure including a shielding layer 21 made of a neutralizing agent between the two inner layers and the outer layer 2B is formed.
この筒状体は適当長さに切断され、一方の切断端を縫着
することにより袋体を形成する。ついでこの袋体の開口
部よりその内部へ酸素発生剤を充填し、前記開口部を同
様にして塞いで収容ケース体２を完成させた後、その外
周に高収縮ビニロン糸４を巻き付けるものである。This cylindrical body is cut to an appropriate length, and one cut end is sewn to form a bag. Next, an oxygen generating agent is filled into the inside of the bag through the opening, and the opening is closed in the same manner to complete the housing case body 2, after which a high shrinkage vinylon thread 4 is wrapped around the outer circumference of the housing case body 2. .
図示例の酸素発生部材１を水中へ投入すると、高収縮ビ
ニロン糸４が短時間で収縮して、収容ケース体２の外周
面全体を締め付ける。この加圧作用により酸素発生剤３

押し出されて、酸素発生部材１は水底に沈む。酸素発生
部材１中の酸素発生剤３は、水に溶けて反応し長時間に
わたり酸素を発生する。When the illustrated oxygen generating member 1 is put into water, the high shrinkage vinylon thread 4 contracts in a short time and tightens the entire outer peripheral surface of the housing case body 2. Due to this pressurizing action, the oxygen generating agent 3
At the same time, the air inside the housing case body 2 is pushed out to the outside, and the oxygen generating member 1 sinks to the bottom of the water. The oxygen generating agent 3 in the oxygen generating member 1 dissolves in water and reacts to generate oxygen over a long period of time.
ところで酸素発生剤３中のクエン酸は水に可溶であるか
ら、収容ケース体２を通過して水中へ浸出しようとする
。この時クエン酸は、中和剤を塗布した遮蔽層２１を通
過することになるため、この中和剤によって中和され、
電離した水素イオンのケース体外への浸出が阻止されて
、水中のｐＨの低下が抑えられる。By the way, since the citric acid in the oxygen generating agent 3 is soluble in water, it passes through the housing case body 2 and tends to leach into the water. At this time, citric acid passes through the shielding layer 21 coated with a neutralizing agent, so it is neutralized by this neutralizing agent.
Ionized hydrogen ions are prevented from leaching out of the case body, and a drop in the pH of the water is suppressed.
なお上記の実施例では、収容ケース体２として不織布を
袋状に形成したものを用いているが、これに限らず、通
気性および通水性を有するものであれば、いかなる材料
、形態のものであってもよい。In the above embodiment, a non-woven fabric formed into a bag shape is used as the housing case body 2, but it is not limited to this, and any material or shape may be used as long as it has air permeability and water permeability. There may be.
また上記実施例では、不織布に中和剤を塗布することで
遮蔽層２１を形成しているが、この遮蔽層２１は塗布以
外の方法（例えば含浸、吹付は等）を用いて形成するこ
ともできる。Further, in the above embodiment, the shielding layer 21 is formed by applying a neutralizing agent to the nonwoven fabric, but the shielding layer 21 may also be formed using a method other than coating (for example, impregnation, spraying, etc.). can.
さらに上記の実施例では、中和剤を用いて遮蔽層２１を
形成しているが、この遮蔽層２１は、クエン酸等のケー
ス体外への浸出を防止するものであれば、中和剤■以外
のものを用いることも可能である。たとえば半透膜で遮
蔽層２１を形成することも理論上句えられ、この場合に
半透膜は、水分子や酸素分子は通すが、クエン酸のよう
に大きな分子は通さないので、クエン酸の水中への浸出
が防止できることになる。Furthermore, in the above embodiment, the shielding layer 21 is formed using a neutralizing agent, but if the shielding layer 21 prevents citric acid or the like from leaching out of the case body, the neutralizing agent It is also possible to use other materials. For example, it is theoretically possible to form the shielding layer 21 with a semi-permeable membrane. In this case, the semi-permeable membrane allows water molecules and oxygen molecules to pass through, but does not allow large molecules such as citric acid to pass through. leaching into the water can be prevented.

の状況を観察した。Experimental Example> Three striped shrimp were placed in an aquarium filled with 7N of water at a temperature of 24°C, and one oxygen generating member according to the present invention was added to the water.
Hydrogen ion concentration (pH) over time
We observed the changes in the shrimp and the status of the striped shrimp. In addition, three striped shrimp were placed in an aquarium under the same conditions, and one oxygen-generating member with a conventional structure without a shielding layer was introduced into the water. I observed the situation.

少している。As shown in Table 1, since the conventional oxygen generating member does not have a shielding layer made of a neutralizing agent, the acid in the oxygen generating agent leaches into the water and the pH of the water decreases over time. Therefore, after 24 hours, all the striped shrimp in the water are dead. In contrast, the oxygen generating member of the invention is provided with a shielding layer made of a neutralizing agent, so that the leaching acid is neutralized and the pH of the water is maintained at around 7. Therefore, the negative effects of the pH drop have been removed, and the number of dead shrimp in the water has been significantly reduced.

きる等、発明目的を達成した効果を奏する。<Effects of the Invention> As described above, this invention is configured to provide a shielding layer on the storage case body to prevent acid from leaching out of the case body, so it is possible to prevent a drop in the pH of the liquid and prevent any negative effects on live fish. The invention has the effect of achieving the purpose of the invention, such as being able to eliminate.
