Description

本発明は、育児や介護の現場で発生する大量の水分を含む尿、便の処理だけでなく、所定の場所以外で排出されるおう吐物の処理にも好適で、かつその後の廃棄処分が容易な吸水性シートに関するものである。 The present invention is suitable not only for the treatment of urine and stool containing a large amount of water generated at the site of childcare and nursing care, but also for the treatment of vomiting discharged outside a predetermined place, and subsequent disposal is easy. The present invention relates to a water absorbent sheet.

従来から、尿、便、おう吐物などの汚物の処理や、汚物による汚染の防止を目的として紙おむつをはじめ各種資材が提案されている。例えば、特許文献1には簡易トイレに装着して使用する、袋体の内部に吸収材を配した汚物処理袋が提案されている。 Conventionally, various materials such as disposable diapers have been proposed for the purpose of treating filth such as urine, feces, and vomit and preventing contamination by filth. For example, Patent Document 1 proposes a waste disposal bag in which an absorbent material is disposed inside a bag body that is used by being attached to a simple toilet.

一方、おう吐物の場合は、多量の水分を含んでいること、O−157やノロウィルスなどを含んでいる可能性もあることもあり、また、予期しない場所に排泄されることから、例えば、手袋、マスクを着用して、吸水剤、殺菌剤及び防臭剤を含有する嘔吐物処理剤(特許文献2)等を散布しておう吐物を脱水固化させ、固化したおう吐物を箒で掃きとって廃棄する方法が提案されている。 On the other hand, in the case of vomiting, it may contain a large amount of water, may contain O-157, norovirus, etc., and is excreted in an unexpected place. Wear gloves and a mask, dehydrate and solidify the vomit that is sprayed with a vomit treatment agent (Patent Document 2) containing a water-absorbing agent, bactericidal agent, and deodorant, and sweep the solid vomit Disposal methods have been proposed.

また、特許文献3には、液透過性の表面シートと、液吸収性の吸収体と、液不透過性の裏面シートを積層させた使い捨ての介護用シートが提案され、特許文献4には、シーツ本体の上にシート状おむつを配置した、おむつ交換時に敷布団やマットレス、掛け布団、衣服(パジャマのズボンなど)が汚れるのを防止できおむつ交換を容易化する医療又は介護用シーツが提案されている。 Patent Document 3 proposes a disposable nursing sheet in which a liquid-permeable top sheet, a liquid-absorbing absorber, and a liquid-impermeable back sheet are laminated. A sheet of diapers on the sheet body has been proposed, and sheets for medical or nursing care have been proposed that make it easy to change diapers by preventing mattresses, mattresses, comforters and clothes (such as pajamas trousers) from becoming dirty when changing diapers. .

更に、手を汚さずに糞便を掴んで袋に入れる機能を解決すべき課題としたペットの糞便の処理材として、特許文献5には、左右一対の指挿入部を形成したシート状物を二つ折りして、これらの指挿入袋部の開口端を上向きにした状態で親指とその他の指とをこれらの指挿入袋部に差し込んで開閉することにより排泄物を掴持したのち、上記被覆片をその上端縁から折り返して反転させることにより、排泄物を包み込むことができるペットの汚物処理具が、特許文献6には、袋の先端を水かきのついた手袋状とすることで、糞便を容易に掴むことができ、それを裏返すとそのまま袋に収納できる汚物処理用手袋が提案されている。 Furthermore, as a treatment material for pet feces, which is a problem to be solved for the function of grasping feces without putting their hands in the bag and placing them in a bag, Patent Document 5 discloses two sheet-like materials having a pair of left and right finger insertion portions. Folding and holding the excrement by inserting and closing the thumb and other fingers into these finger insertion bag portions with the open ends of these finger insertion bag portions facing upward, The pet waste disposal tool that can wrap the excrement by folding it back from its upper edge is disclosed in Patent Document 6, in which the tip of the bag is shaped like a glove with a webbed, facilitating feces. There has been proposed a waste disposal glove that can be held in a bag and stored in a bag as it is turned over.

しかしながら、上述した資材は、各々目的とする用途に適したものではあるが、目的外の用途に利用できるものではなく、また携帯性か、使用後の処分のいずれかに問題があるものが多かった。例えば、特許文献1の汚物処理袋は簡易トイレ或いはその代替物への使用には好適であるがそれ以外の用途への利用できないものであり、おう吐物を処理するためには特許文献2の嘔吐物処理剤に加えて、少なくとも手袋や箒などが必要であり、更にはせっかく固化させたおう吐物を処分するための袋も必要となるなど携帯性、使用後の処分に問題があるものであった。 However, each of the materials described above is suitable for the intended use, but it cannot be used for any other purpose, and there are many problems in either portability or disposal after use. It was. For example, the waste disposal bag of Patent Document 1 is suitable for use in a simple toilet or its substitute, but cannot be used for other purposes. In addition to the material treatment agent, at least gloves and scissors are required, and there is also a problem in portability and disposal after use, such as a bag for disposing of the solidified vomiting. It was.

また、特許文献3の介護用シートは広範囲に利用されており、特許文献4のような用途にも使用されているが、これらのシートは排尿による布団やマットレスの汚染を防ぐには好適ではあるが、尿を吸収した面がむき出しになるので、尿に触れないように廃棄処分することは困難であった。また、特許文献5、6のペットの糞便処理具は、手袋を別途必要とすることなく糞便を袋に入れて運搬処分できるという携帯性に優れたものであるが、水分の多い下痢便や尿等に適用できるものではなかった。 Moreover, although the sheet for care of patent document 3 is used widely, and it is used also for uses like patent document 4, these sheets are suitable for preventing the contamination of the futon and mattress by urination. However, since the surface that absorbed urine was exposed, it was difficult to dispose of the urine without touching it. Moreover, although the pet feces disposal tool of patent documents 5 and 6 is excellent in the portability which can carry and dispose of feces in a bag, without separately requiring gloves, diarrheal feces and urine with much water It was not something that could be applied.

本発明は、上述した用途のいずれにも適用可能であり、しかも携帯性に優れ、尿、便、おう吐物などの処理物の処理に適し、処理後の運搬・廃棄用の袋を用意する必要もない吸水性シートを工業的に安価に適用することを目的とする。 The present invention can be applied to any of the above-mentioned applications, has excellent portability, is suitable for processing of processed products such as urine, feces, and vomitus, and needs to prepare a bag for transportation and disposal after processing. The object is to industrially apply a water-absorbent sheet at low cost.

本発明者は、鋭意検討した結果、透水性膜と非透水性膜とで形成される袋の内部に特定値以上の吸水能力を有する吸収体2を非拘束状態で配し、かつ反対面を非透水性膜とカバーフィルムからなり、該カバーフィルムをほぼ2等分する切り離し個所を開口部とする袋に形成した吸水性シートが、尿、便、おう吐物などの処理物の処理に適し、しかも処理後、開口部の個所で裏返すことによりそのまま処理物を入れた袋として使用できることを見いだし本発明にいたった。 As a result of intensive studies, the inventor has arranged the absorbent body 2 having a water absorption capacity of a specific value or more in an unconstrained state inside a bag formed of a water permeable film and a water impermeable film, and has the opposite surface. A water-absorbent sheet comprising a non-water-permeable membrane and a cover film, formed in a bag having an opening at a cut-off portion that divides the cover film into two equal parts, is suitable for the treatment of processed products such as urine, feces, and vomiting, And after processing, it turned out by turning over in the part of an opening part, it discovered that it could use as a bag which put the processed material as it was, and came to this invention.

In addition, the hatching part of a periphery shows a junction part (heat seal part). 吸水性シート10の層構成を説明するための、図1のAA’線断面模式図である。FIG. 2 is a schematic cross-sectional view taken along the line AA ′ of FIG. 1 for illustrating the layer configuration of the water absorbent sheet 10. 本発明の吸水性シート10の透水性膜1側を上面にして、開口部41を拡げて容器5に被せて使用する態様を示す斜視図である。It is a perspective view which shows the aspect which uses the water-permeable sheet 1 side of the water-absorbent sheet 10 of the present invention on the upper surface, expands the opening 41 and covers the container 5. 本発明の吸水性シート10を開口部41のところで裏返して、底面内側が透水性膜1、底面外側が非送水性膜2、側面がカバーフィルム4からなる、運搬廃棄用袋或いは汚物収容袋として利用する態様を示す斜視図である。The water-absorbent sheet 10 of the present invention is turned upside down at the opening 41, as a transport disposal bag or a filth-containing bag comprising a water-permeable membrane 1 on the bottom side, a non-water-feed film 2 on the bottom side and a cover film 4 on the side. It is a perspective view which shows the aspect utilized.

本発明の吸水性シート10は、透水性膜1、30g/100cm以上の吸水能力(蒸留水)を有する吸収体2、非透水性膜3、カバーフィルム4の順序に積層されている。ここで、透水性膜1は、尿、便、おう吐物などの処理物中の水分を吸収体2まで通過させる機能と、吸収体2若しくは吸収体2の構成物が吸水性シート10から脱落するのを防止する機能を有している。透水性膜1としては、上記機能を有するものであれば特に制限はないが、例えば、ポリエチレンやポリプロピレン等のポリオレフィン系、ポリエステル系、ポリアミド系の合成繊維、レーヨンやキュプラ等の再生繊維、綿等の天然繊維を繊維素材として、スパンレース法、スパンボンド法、サーマルボンド法、メルトブローン法、ニードルパンチ法等の適宜の加工法によって加工した不織布や、天然繊維や合成繊維からなる織布、或いはポリエチレンフィルム、ポリプロピレンフィルム、ナイロンフィルム、ポリエステルフィルム或いはこれらを適宜積層したラミネートフィルムに穴あけ加工を施した多孔フィルムやメッシュフィルムなどが好適に使用できる。本発明においては、これらの中でも安価で十分な強度と優れた透水性を有する不織布が好ましく使用される。特に、レーヨンやキュプラ等の再生繊維、綿等を素材として全部または一部使用した不織布や親水化処理を施した、親水性を有する不織布を使用するのが好ましい。 The water-absorbent sheet 10 of the present invention is laminated in the order of a water-permeable membrane 1, an absorbent body 2 having a water absorption capacity (distilled water) of 30 g / 100 cm 2 or more, a water-impermeable membrane 3, and a cover film 4. Here, the water permeable membrane 1 has a function of allowing moisture in the processed material such as urine, feces, and vomitus to pass to the absorbent body 2 and the absorbent body 2 or the component of the absorbent body 2 is dropped from the water absorbent sheet 10. It has a function to prevent this. The water permeable membrane 1 is not particularly limited as long as it has the above-mentioned functions. For example, polyolefin-based fibers such as polyethylene and polypropylene, polyester-based and polyamide-based synthetic fibers, regenerated fibers such as rayon and cupra, cotton, and the like Non-woven fabrics made from natural fibers of the above, processed by an appropriate processing method such as the spunlace method, spunbond method, thermal bond method, meltblown method, needle punch method, woven fabric made of natural fibers or synthetic fibers, or polyethylene A porous film, a mesh film, or the like obtained by punching a film, a polypropylene film, a nylon film, a polyester film, or a laminate film obtained by laminating these appropriately can be preferably used. In the present invention, among these, a nonwoven fabric that is inexpensive and has sufficient strength and excellent water permeability is preferably used. In particular, it is preferable to use a non-woven fabric having hydrophilicity, or a non-woven fabric using all or part of recycled fibers such as rayon and cupra, and cotton as a raw material.

さて、本発明において吸収体2は、尿、便、おう吐物などの処理物中の水分を吸収することによって、処理物を処理しやすい固形若しくは半固形とするためのものであり、透水性膜1と非透水性膜3とで形成される袋13の内部に非拘束状態で配されている。したがって、吸収体2は、シート状とすることが好ましい。そして、例えば、排尿の処理を目的とする場合は、500g(生理食塩水)程度の吸水量を必要とし、排便の処理の場合は、最も水分量の多い下痢便を想定して200g(生理食塩水)程度の吸水量を必要とするのに対して、単なる汚物入れに使用する場合ひ必要とする吸水量は、せいぜい100g(蒸留水)程度であるから、多種多様な用途で使用可能とするためには、少なくとも300g(生理食塩水)以上、好ましくは500g(生理食塩水)以上を吸水できる吸収体2を使用する必要がある。 Now, in the present invention, the absorbent body 2 is for making the treated product a solid or semi-solid that is easy to treat by absorbing moisture in the treated product such as urine, feces, vomitus, etc. 1 and the water-impermeable membrane 3 are disposed in an unconstrained state inside a bag 13 formed by the water-impermeable membrane 3. Therefore, the absorbent body 2 is preferably a sheet. For example, in the case of urination treatment, a water absorption amount of about 500 g (physiological saline) is required, and in the case of stool treatment, 200 g (physiological saline) is assumed assuming the diarrheal stool with the highest water content. The water absorption amount is about 100 g (distilled water) at most, so that it can be used in a wide variety of applications. Therefore, it is necessary to use the absorbent body 2 that can absorb at least 300 g (physiological saline) or more, preferably 500 g (physiological saline) or more.

吸収体2の吸水量(g)は、
吸水量(g)=吸水能力(g/100cm)×吸水体の面積(cm)/100
なる式で計算することができ、吸水量を大きくするためには吸収体2の吸水能力を大きくするか、或いは吸収体2の面積を大きくする必要があるが、吸収体2の面積は、吸水性シート10の袋13の大きさ以上にすることはできないから、吸水能力の大きい吸収体2を使用することが必要となる。また、吸水剤(特に、吸水性ポリマー)によっては、蒸留水に比べて生理食塩水に対する吸水能力が極端に低下する現象がみられるので、本発明の吸水性シート10においては、30g/100cm以上の吸水能力(蒸留水)、好ましくは、50g/100cm以上の吸水能力(蒸留水)を有する吸収体2を使用する必要がある。逆に、吸水能力(蒸留水)が30g/100cm未満では、本発明の目的にかなった吸水性シート10を提供することができないので好ましくない。
The water absorption amount (g) of the absorber 2 is
Water absorption amount (g) = Water absorption capacity (g / 100 cm 2 ) × Absorbent body area (cm 2 ) / 100
In order to increase the amount of water absorption, it is necessary to increase the water absorption capacity of the absorber 2 or to increase the area of the absorber 2, but the area of the absorber 2 is Since it cannot be made larger than the size of the bag 13 of the adhesive sheet 10, it is necessary to use the absorbent body 2 having a large water absorption capacity. Further, depending on the water-absorbing agent (particularly, the water-absorbing polymer), a phenomenon in which the water-absorbing ability with respect to physiological saline is extremely reduced as compared with distilled water is observed. Therefore, in the water-absorbent sheet 10 of the present invention, 30 g / 100 cm 2. It is necessary to use the absorbent body 2 having the above water absorption capacity (distilled water), preferably 50 g / 100 cm 2 or more. On the other hand, if the water absorption capacity (distilled water) is less than 30 g / 100 cm 2 , it is not preferable because the water absorbent sheet 10 that meets the object of the present invention cannot be provided.

上述する吸水能力を本発明で使用する吸収体2に付与するためには、自身の重量の数百倍の吸水能力を有するとされる吸水性ポリマーを使用することが好ましく、例えば、吸水性ポリマーとパルプ等の吸水材を併用したものが特に好ましく使用される。吸水性ポリマーとしては、ポリアクリル酸塩架橋物、自己架橋したポリアクリル酸塩、アクリル酸エステル−酢酸ビニル共重合体架橋物のケン化物、イソブチレン・無水マレイン酸共重合体架橋物、ポリスルホン酸塩架橋物や、ポリエチレンオキシド、ポリアクリルアミドなどの水膨潤性ポリマーを部分架橋したもの等が挙げられるが、本発明においては、吸水能力、吸水速度に優れるポリアクリル酸ナトリウムで代表されるアクリル酸塩系の吸水性ポリマーを使用するのが好ましい。また、パルプとしては、木材から得られる化学パルプ、溶融パルプ等のセルロース繊維や、レーヨン、アセテート等の人工セルロース繊維からなるものが挙げられる。また、吸収体2には必要に応じて、消臭剤、殺菌剤等を含有させることももちろん可能である。 In order to impart the above-described water absorption capability to the absorbent body 2 used in the present invention, it is preferable to use a water-absorbing polymer that has a water absorption capability of several hundred times its own weight. A combination of water absorbent material such as pulp and the like is particularly preferably used. Water-absorbing polymers include cross-linked polyacrylate, self-crosslinked polyacrylate, saponified acrylate-vinyl acetate copolymer, cross-linked isobutylene / maleic anhydride copolymer, polysulfonate Examples include cross-linked products and partially cross-linked water-swellable polymers such as polyethylene oxide and polyacrylamide. In the present invention, the acrylate system represented by sodium polyacrylate having excellent water absorption capacity and water absorption speed. It is preferable to use the water-absorbing polymer. Examples of the pulp include cellulose fibers such as chemical pulp and molten pulp obtained from wood, and artificial cellulose fibers such as rayon and acetate. Of course, the absorbent body 2 can contain a deodorant, a bactericide and the like, if necessary.

非透水性膜3としては、透水性膜1上に残存する処理物や、透水性膜1を通過して吸収体2に吸収された尿、便、おう吐物などを非透水性膜3の裏側(カバーフィルム4側)に到達させない機能、すなわち、袋43に手を入れて作業する際には手を汚染しないこと、処理後に開口部41で裏返したときに廃棄処理される処理済みの汚物の収納袋として使用できること、を十分果たすものであれば特に制限はなく、包装材として使用されるポリエチレンフィルム、ポリプロピレンフィルムなどの合成樹脂フィルムが好ましく使用される。 As the water-impermeable membrane 3, processed matter remaining on the water-permeable membrane 1, urine, feces, vomitus and the like that have passed through the water-permeable membrane 1 and have been absorbed into the absorbent body 2 are backside of the water-impermeable membrane 3. Function not to reach (the cover film 4 side), that is, do not contaminate the hand when working with the bag 43, the treated filth that is discarded when turned over at the opening 41 after processing There is no particular limitation as long as it can sufficiently be used as a storage bag, and a synthetic resin film such as a polyethylene film or a polypropylene film used as a packaging material is preferably used.

カバーフィルム4としては、非透水性膜3と同様に包装材として使用されるポリエチレンフィルム、ポリプロピレンフィルムなどの合成樹脂フィルムが好ましく使用される。 As the cover film 4, a synthetic resin film such as a polyethylene film or a polypropylene film used as a packaging material in the same manner as the water-impermeable membrane 3 is preferably used.

さて、本発明の吸水性シート10において、吸収体2は、透水性膜1と非透水性膜3の周縁部同士を接合して形成される袋13の内部に非拘束状態で配された構造となっている。このような構造とすることによって、吸収体2は、透水性膜1や非透水性膜3に拘束されることなく吸水して三次元方向に自在に膨張することができ、その結果、貼り合わせ等により拘束した場合のように、本来有している吸水能力を制限することなく、能力通りの水分を吸収することが可能となるのである。なお、透水性膜1と非透水性膜3の接合はプラスチック袋の製造において常用される熱シールによるのが一般的であるが、熱シール特性に乏しい材質の場合はホットメルト接着剤などの接着剤を使用して接合することももちろん可能である。 Now, in the water-absorbent sheet 10 of the present invention, the absorbent body 2 is arranged in an unconstrained state inside a bag 13 formed by joining the peripheral portions of the water-permeable membrane 1 and the water-impermeable membrane 3 together. It has become. By adopting such a structure, the absorbent body 2 can absorb water without being constrained by the water permeable film 1 or the water impermeable film 3 and can freely expand in a three-dimensional direction. As in the case of restraint by the above, it is possible to absorb moisture according to the capacity without limiting the inherent water absorption capacity. The water-permeable membrane 1 and the non-water-permeable membrane 3 are generally joined by heat sealing that is commonly used in the manufacture of plastic bags. However, in the case of a material having poor heat sealing properties, bonding such as a hot melt adhesive is used. Of course, it is also possible to join using an agent.

また、カバーフィルム4は、透水性膜1や吸収体2とは反対側の面の非透水性膜3と全周に渡って周縁部で接合されている。そして、カバーフィルム4はほぼ2等分するように切り離し又は切り離し可能に形成され、当該切り離し個所を開口部41とする非透水性膜3とカバーフィルム4からなる袋43が形成されている。これによって、汚物の処理作業時には手袋の代わりに当該袋状部43に手を挿入して作業することができる。ここで切り離し可能というのは、例えば、ミシン目などを設けておいて処理作業直前にこのミシン目部分を切り離すことができるということを意味している。なお、本発明においては、例えば、二つ折りしたフィルムや折りたたんだチューブ状フィルムの一方の面が非透水性膜3、もう一方の面がカバーフィルム4となるように、そのまま、透水性膜1と接合すれば、一度の積層工程で本発明の吸水性シート10を製造することができるので好ましい。 Further, the cover film 4 is joined to the non-permeable membrane 3 on the surface opposite to the permeable membrane 1 and the absorber 2 at the peripheral edge over the entire circumference. Then, the cover film 4 is formed so as to be separated or separable so as to be roughly divided into two equal parts, and a bag 43 made of the water-impermeable film 3 and the cover film 4 having the separation part as an opening 41 is formed. Thus, it is possible to insert a hand into the bag-like portion 43 instead of the gloves during the waste disposal operation.
