Description
【発明の詳細な説明】 （産業上の利用分野） 本発明は使捨ておむつに関する。[Detailed description of the invention] (Industrial application field) The present invention relates to disposable diapers.
（従来の技術）
おむつ本体内に収納されている吸水体がウッドバルブ、
繊維等の不織布等で形成されている。(Conventional technology) The water absorbent body housed in the diaper body is a wood valve,
It is made of nonwoven fabric such as fiber.
（発明が解決しようとする問題点）
ところで、従来の使捨ておむつでは、尿の吸収能力を不
織布にほとんど依存しており、不織布聞の大小で吸収能
力が決められている。(Problems to be Solved by the Invention) By the way, in conventional disposable diapers, the urine absorption capacity is almost entirely dependent on the nonwoven fabric, and the absorption capacity is determined by the size of the nonwoven fabric.
そのために、必要とされる不織布は使捨てられるもので
あるだけに消費量が馬鹿にならず、又、不織布の吊に比
例して、不織布自体の単位時間当りの吸水スピードが排
尿流量に追いつかないことによるところの問題が一層増
長することになる。For this reason, since the required nonwoven fabric is disposable, its consumption is not insignificant, and in proportion to the hanging of the nonwoven fabric, the water absorption speed per unit time of the nonwoven fabric itself cannot keep up with the flow rate of urine. This will likely exacerbate the problem.
特に、吸水体における吸収面側に尿膜ができて、吸収ス
ピードが著しく低下する。In particular, an allantoic membrane is formed on the absorption surface side of the water absorbent body, which significantly reduces the absorption speed.
しかも、おむつは不織布の高張りによって全体が嵩高で
、流通段階での包装、保管、運搬１店頭販売、購入の各
段階で、−その大形であることによるところの種々の問
題を有している。In addition, diapers are bulky as a whole due to the high tension of the non-woven fabric, and their large size poses various problems at each stage of packaging, storage, transportation, sales at stores, and purchasing during the distribution stage. There is.
もっとも、吸収体を圧縮した状態に包装してコンパクト

縮状態を解いても、吸収体の不織布の復元が不十分で、
当初の吸収能力、特に毛細管通路の消失によるところの
吸収スピードの著しい低下を免れない問題が生じる。However, it is also possible to package the absorbent body in a compressed state to make it compact, but in this case, even if the compressed state is released at the time of use, the nonwoven fabric of the absorbent body is not sufficiently restored.
A problem arises in which the initial absorption capacity, especially the absorption speed due to the disappearance of capillary channels, is significantly reduced.
本発明はこのような事情に鑑みてなされたもので、少な
い不織布量で吸収能力が高く、しかも使用前までコンパ
クトにできて、使用時にはその高い吸収能力を発揮する
有用な使捨ておむつを提供することを目的とする。The present invention has been made in view of these circumstances, and provides a useful disposable diaper that has high absorption capacity with a small amount of nonwoven fabric, can be made compact before use, and exhibits its high absorption capacity during use. The purpose is to

・A water absorbent is stored inside the diaper body, which is made of parts,
This water absorbent body is characterized in that it is made of a film formed from a mixture of a nonwoven fabric, a granular gelling agent, and a strip-like filling element made of synthetic resin.

状態に無理なく復元するようにしている。The filling element (11) is mixed in an appropriate amount in the nonwoven fabric (9), and flows through the nonwoven fabric (9) due to the elastic force of the element itself.
> is enlarged and the volume of the nonwoven fabric (9) is increased to make it bulky. The elastic force of the filling element (11) can be freely adjusted by selecting the softness or hardness of the material, and the hardness of the water absorbent body (7) itself can also be adjusted to a certain extent, and especially the water absorption body (7)
When the pressure is released from the compressed state, the bulky state, that is, the flow passageway (a) is enlarged, and the state is restored to a state with high absorption efficiency without difficulty.

吸収能力を設定通りに発揮することができる。Further, in an embodiment in which the gelling agent (10) is attached to each filling element (11), the gelling agent (10) is attached to the water absorbent (7).
Urine is uniformly distributed within the water absorbent body (7), and gelation of urine is performed evenly throughout the entire interior of the water absorbent body (7), so that the required absorption capacity can be exerted as set without any absorption spots appearing.
（発明の効果） したがって本発明によれば次の利点がある。(Effect of the invention) Therefore, the present invention has the following advantages.
■ 単位時聞当りの排油量が人である尿を、その排泄位
置の吸収面部分そして吸収体部分から吸水体内を流々通
路に沿い移動案内して吸水体内全域に迅速に流入せしめ
て、排泄個所から急速に吸収することができて、排泄位
置における吸収しきれない尿の拡がりを最小限に抑さえ
且つ尿をゲル状にゲル化して、従来品よりも格段快適に
使用なさしめることができる。■ The amount of urine excreted per unit time is that of a person's urine, which is guided through the absorbent body from the absorbent surface portion at the excretion position and the absorbent body portion along the flow path, so that it quickly flows into the entire area of the absorbent body, and is excreted. It can be rapidly absorbed from the spot, minimizing the spread of unabsorbed urine at the excretion site, and it also turns the urine into a gel, making it much more comfortable to use than conventional products. .
■ 充填要素が不織布の減罎分を充足して変わらぬ吸収

したものより賄えて経湾的効果も優れている。■ The filling element satisfies the shrinkage of the non-woven fabric and maintains a constant absorption capacity, which contributes to the saving of resource consumption such as wood valves for non-woven fabric, and the filling element can be used for various products made of synthetic resin sheets. It can cover the cutting edges produced from the ground compared to the crushed one, and has a better effect on the bay.

Then, when the compressed state is released during use, the flow passage is restored by the elastic force of the filling element, and the high absorption effect can be exhibited to reliably absorb urine.
