Description

使い捨て排泄物処理具Disposable excrement disposal tool
　本発明は、所定温度より高いある温度未満の水には水解または水溶しないが、前記ある温度以上の温度の水に水解または水溶する材料（紙材、合成樹脂材または天然素材）からなる使い捨て排泄物処理具に関し、具体的には、基材である積層紙を熱プレス成型して製造する排泄物処理具に関する。 The present invention is a disposable excretion made of a material (paper material, synthetic resin material or natural material) that does not hydrolyze or dissolve in water below a certain temperature higher than a predetermined temperature, but does not hydrolyze or dissolve in water above the certain temperature. More specifically, the present invention relates to an excrement disposal tool produced by hot press molding a laminated paper as a base material.
　従来、たとえば使い捨ておむつは普通ごみまたは産業廃棄物として焼却処理されるのが通常である。行政にとっても、使い捨ておむつを焼却処理するために、多くのエネルギーが消費され、二酸化炭素の排出量も多くなる。
　ところで、使用済みの使い捨ておむつは容積が大きいため、通常は、水洗便器に流すことができない。
　使い捨ておむつの素材自体を水に水解または水溶しやすい材料で構成することも考えられるが、尿によりおむつの素材が水解または水溶してしまうため、この手法を採用することはできない。
　一方、使用後の使い捨ておむつを回収し、回転ドラムにより８０－９０℃の高温水に浸漬させた状態で回転させ、これにより使用後のおむつを不溶成分と可溶成分とに遠心分離する技術も知られている（特許文献１）。しかし、この遠心分離技術は設備が大掛かりであり、コストが膨大となるため実現には至っていない。 Conventionally, for example, disposable diapers are usually incinerated as ordinary garbage or industrial waste. For the government as well, incineration of disposable diapers consumes a lot of energy and increases carbon dioxide emissions.
By the way, since a used disposable diaper has a large volume, it cannot normally be poured into a flush toilet.
Although it is conceivable that the disposable diaper material itself is made of a material that is easily hydrolyzed or water-soluble in water, this method cannot be adopted because the material of the diaper is hydrolyzed or water-soluble by urine.
On the other hand, there is also a technique for collecting disposable diapers after use, rotating them in a hot drum at 80-90 ° C. with a rotating drum, and centrifuging the used diapers into insoluble components and soluble components. Known (Patent Document 1). However, this centrifugal separation technology has not been realized since it requires a large amount of equipment and the cost is enormous.

　ところで、使い捨ておむつを普通ごみとして廃棄する場合を考える。通常、多くの行政区では、普通ごみの回収は一週間に２回程度しか行わない。
　その結果、回収されない使用済みのおむつから排泄物の匂いが出るし、さらに使用済みのおむつは蝿の発生の温床ともなるという問題がある。
　もちろん、使用済生理ナプキン、尿漏れパッド等についても同様のことが言える。 By the way, the case where a disposable diaper is discarded as normal waste is considered. Usually, in many administrative districts, regular garbage is collected only twice a week.
As a result, there is a problem that the smell of excrement comes out from the used diaper that is not collected, and the used diaper also becomes a hotbed for generation of sputum.
Of course, the same applies to used sanitary napkins, urine leak pads, and the like.
　本発明の目的は、基材の全部または一部が、所定温度（たとえば３８℃）より高いある温度未満の水には水解または水溶しないが、前記ある温度以上の水に水解または水溶する紙材、合成樹脂材または天然素材からなる使い捨て排泄物処理具を提供することである。
　本発明の他の目的は、基材の全部または一部が、所定温度（たとえば、３８℃）より高いある温度（たとえば、４１℃）未満の水には水解または水溶しないが、前記ある温度以上の他の温度（たとえば、４５℃）の水に水解または水溶する紙材、合成樹脂材または天然素材からなる使い捨て排泄物処理具を提供することである。 An object of the present invention is to provide a paper material in which all or a part of the base material does not hydrolyze or dissolve in water below a certain temperature higher than a predetermined temperature (for example, 38 ° C.), but hydrolyzes or dissolves in water above the certain temperature. It is to provide a disposable excrement disposal tool made of a synthetic resin material or a natural material.
Another object of the present invention is that the whole or a part of the substrate does not hydrolyze or dissolve in water below a certain temperature (for example, 41 ° C.) higher than a predetermined temperature (for example, 38 ° C.). It is to provide a disposable excrement disposal tool made of a paper material, a synthetic resin material, or a natural material that is hydrolyzed or water-soluble in water at another temperature (for example, 45 ° C.).

　本発明の排泄物処理具では、基材はたとえば３８℃より高いある温度未満の水には水解または水溶しないが、当該ある温度以上の水に水解または水溶するようにできる。この場合、装用者の体温が平熱（３６～３７℃前後）であれば、装用中に基材から尿が漏れるといった不都合は生じない。
　また、本発明の排泄物処理具では、基材はたとえば４３℃より高いある温度未満の水には水解または水溶しないが、当該ある温度以上の水に水解または水溶するようにできる。この場合、装用者の体温が平熱以上であったとしても、通常、体温は４３℃を超えることはごくまれであるので、装用中に基材から尿が漏れるといった不都合は生じない。
　基材の原料価格、入手の容易性、基材の特性等を考慮し、前記紙材、前記合成樹脂材または前記天然素材として、所定温度（３８～５０℃）より高いある温度未満の水には水解または水溶しないが、当該ある温度以上の水には水解または水溶するものが適宜選択できる。
　一方、本発明では、基材を、所定温度（たとえば３８℃）より高いある温度未満の水には水解または水溶しないが、当該ある温度以上の水には水解または水溶する部分（上記「基材の一部」）と、ある温度未満（２０℃程度）の水でも水解または水溶する部分（上記「基材の残部」、たとえば吸水パッド）により構成することができる。この場合、「基材の一部」は３８℃未満だと水に水解または水溶しないが、「基材の残部」は３８℃未満で（たとえば、２０℃であったとしても）水に水解または水溶する。 Fig. 5 shows the temperature characteristics of the base material when it is hydrolyzed or water-soluble in water that is not hydrolyzed or water-soluble in water lower than a certain temperature that is higher than a predetermined temperature but water that is above the certain temperature. 1 (A).
In addition, a part of the base material does not hydrolyze or dissolve in water below a certain temperature higher than a predetermined temperature, but hydrolyzes or dissolves in water above the certain temperature, and the remainder of the base material is water below the certain temperature. FIG. 1B shows the temperature characteristics of the hydrolysis and water-solubility of the base material when it is hydrolyzed or water-soluble (for example, water at 20 ° C.).
In the present invention, for example, when a test based on JIS P4501 (quality standard test for ease of loosening of toilet paper, etc.) is performed on a sample (a piece of excrement disposal tool) using water at a certain temperature, it does not exceed 100 seconds May be “hydrolyzed or water-soluble in water”, and may be “hydrolyzed or water-insoluble in water” when it exceeds 100 seconds.
In the test method of JIS P4501, a 114 mm square test piece is put into water stirred at 600 revolutions per minute, and the rotational speed temporarily drops to about 500 revolutions due to the resistance of the test piece. The number of revolutions increases as the test piece unwinds, and the time to recover from the test piece to 540 revolutions is measured.
In the excrement disposal tool of the present invention, the base material may be a paper material composed of a single sheet of paper, or, as will be described later, in addition to a laminate of a plurality of papers or paper, It may be comprised from the laminated body containing a property sheet | seat film (it can be comprised from a synthetic resin, an organic substance sheet | seat film), and a hydrolyzed natural material sheet | seat film.
In the excrement disposal tool of the present invention, the base material does not hydrolyze or dissolve in water below a certain temperature, for example, higher than 38 ° C., but can hydrolyze or dissolve in water above the certain temperature. In this case, when the body temperature of the wearer is normal (around 36 to 37 ° C.), there is no inconvenience that urine leaks from the base material during wearing.
In the excrement disposal tool of the present invention, the base material is not hydrolyzed or water-soluble in water below a certain temperature, for example, higher than 43 ° C., but can be hydrolyzed or water-soluble in water above the certain temperature. In this case, even if the body temperature of the wearer is equal to or higher than normal temperature, the body temperature usually rarely exceeds 43 ° C., so that there is no inconvenience that urine leaks from the base material during wearing.
Considering the raw material price of the base material, the availability, the characteristics of the base material, etc., the paper material, the synthetic resin material or the natural material is used in water below a certain temperature higher than a predetermined temperature (38 to 50 ° C.). Is not hydrolyzed or water-soluble, but water that is hydrolyzed or water-soluble can be appropriately selected as the water at a certain temperature or higher.
On the other hand, in the present invention, the base material is not hydrolyzed or water-soluble in water below a certain temperature higher than a predetermined temperature (for example, 38 ° C.), but is hydrolyzed or water-soluble in water above the certain temperature (the above “base material”). And a portion that is hydrolyzed or water-soluble even with water below a certain temperature (about 20 ° C.) (the above “remaining part of the substrate”, for example, a water absorbing pad). In this case, “part of the substrate” is not hydrolyzed or water soluble in water when it is less than 38 ° C., while “the rest of the substrate” is hydrolyzed or dissolved in water at less than 38 ° C. (even if it is 20 ° C., for example). Water soluble.
