Description
本発明は水溶性補強紙に関し、特には破れ難く、また使用後に水洗トイレに流せる水溶性補強紙に関する。 The present invention relates to a water-soluble reinforcing paper, and more particularly to a water-soluble reinforcing paper that is not easily torn and can be poured into a flush toilet after use.
従来、排泄物等を処理し使用後に水洗トイレに流せる水溶性又は水解性の紙製品においては、トイレットペーパーや使い捨ておむつが一般に知られている。 Conventionally, toilet paper and disposable diapers are generally known for water-soluble or water-degradable paper products that can be discharged into a flush toilet after use.
このトイレに流して捨てることが可能な水溶性又は水解性シートとしては、例えば特許文献１（特開２００１−２８８６５７号公報）には表面層を構成する繊維中にフィブリル化レーヨンを含む多層構造の水解性繊維シートが提案されている。 As a water-soluble or water-decomposable sheet that can be thrown away in this toilet, for example, Patent Document 1 (Japanese Patent Laid-Open No. 2001-288657) has a multilayer structure including fibrillated rayon in the fibers constituting the surface layer. A water-decomposable fiber sheet has been proposed.
更に、強化紙としては、特許文献２（特開２００１−２０５７７０号公報）に、包装紙における強構造を目的とする強化包装紙が開示され、これは第１紙製シートと第２紙製シートとを貼り合せ、その貼り合せ界面に紙製紐を間隔をおいて並列に介在して、第１、第２紙製シートと貼り合せた強化包装紙である。 Further, as reinforced paper, Patent Document 2 (Japanese Patent Application Laid-Open No. 2001-205770) discloses a reinforced wrapping paper for a strong structure in wrapping paper, which is a first paper sheet and a second paper sheet. Is a reinforced wrapping paper in which a paper string is interposed in parallel at the bonding interface and is bonded to the first and second paper sheets.
しかしながら、従来のトイレットペーパーは、単にトイレで使用する分には使用後にトイレに流せて便利であるが、他の使用目的に使用する場合、例えば犬の散歩中に犬の排泄物を処理するのに、トイレットペーパーで包んで持ち帰るにしても、極めて破れ易く使用に耐え難い。 However, the conventional toilet paper can be easily used after being used in the toilet as it is used in the toilet, but when used for other purposes, it treats dog excrement during a dog walk, for example. Even if you wrap it in toilet paper and take it home, it is extremely easy to tear and hard to withstand.
他方、使い捨ておむつにおいては、使用後に水解性の表面材を本体から外して、表面材上の排泄物と共にトイレに流して廃棄するため、本体は別に処理しなければならず、更に、使い捨ての目的でおむつ以外に使用するにしても、高価であり、使用がおむつに限定され、汎用性に欠けていた。 On the other hand, in disposable diapers, the water-decomposable surface material is removed from the main body after use, and it is discarded by flushing it with the excrement on the surface material, so that the main body must be treated separately. Even when used for other than diapers, it is expensive, limited to diapers, and lacks versatility.
更に、特許文献１の水解性繊維シートは、トイレに流して捨てることができ、且つ汎用性があり便利であるが、フィブリル化レーヨン処理が高価であり、製造上も複雑でコスト的に高い問題点を有していた。 Furthermore, the water-decomposable fiber sheet of Patent Document 1 can be thrown away in the toilet and is versatile and convenient. However, the fibrillated rayon treatment is expensive, and the manufacturing is complicated and expensive. Had a point.
また、特許文献２の強化紙においては、使用目的が包装紙であり、リサイクル性や焼却処理性には効果を有するが、この包装紙自体、水解性がなくトイレに流して使い捨てに使用するのには全く使用できない問題点を有していた。つまり、この包装紙自体においては、耐水性を備えることはあっても、水溶性を備えるようなことは水にぬれた場合に破れ易くなるため殆んどなく、従って、トイレに流して使い捨てる使用ができない。 Further, in the reinforced paper of Patent Document 2, the purpose of use is wrapping paper, which has an effect on recyclability and incineration, but the wrapping paper itself does not have water decomposability and can be used for disposable use in a toilet. Had problems that could not be used at all. In other words, in this wrapping paper itself, even though it has water resistance, there is little that it has water solubility because it easily breaks when wet, so it is thrown away in the toilet and discarded. Cannot be used.
従って、本発明は、全体が水溶性であり、全体をそのままトイレに流しても水溶性が良好であり、しかも使用時に破れにくい強度を有する水溶性強化紙を提供することを目的とする。 Accordingly, an object of the present invention is to provide a water-soluble reinforced paper that is water-soluble as a whole, has good water-solubility even when the whole is flushed as it is, and has a strength that does not easily break during use.
本発明の他の目的は、水溶性及び強化を備えながら製造コストが極めて安価にできる水溶性強化紙を提供するにある。 Another object of the present invention is to provide a water-soluble reinforced paper that can be manufactured at a very low cost while having water-solubility and reinforcement.
本発明は、表紙シート（１）と裏紙シート（２）との間に、網目状の補強網体（３）を設け、前記表紙シート（１）と前記裏紙シート（２）とを貼着させ、且つ、前記表紙シート（１），前記裏紙シート（２）及び前記補強網体（３）が、それぞれ水溶性又は水解性のものから成る。 In the present invention, a mesh-like reinforcing net (3) is provided between the cover sheet (1) and the back sheet (2), and the cover sheet (1) and the back sheet (2) are pasted. The cover sheet (1), the backing sheet (2), and the reinforcing net (3) are made of water-soluble or water-decomposable materials, respectively.
前記表紙シート（１）と前記裏紙シート（２）が、それぞれ複数枚の水溶性紙シートを水溶性接着剤で接着し重層するのが好ましい。 It is preferable that the cover sheet (1) and the backing paper sheet (2) are laminated by adhering a plurality of water-soluble paper sheets with a water-soluble adhesive.
前記補強網体（３）が、水溶性紙紐で網目状に形成するのが好ましい。 It is preferable that the reinforcing net body (3) is formed in a mesh shape with a water-soluble paper string.
本発明の水溶性補強紙は、表紙シート（１）及び裏紙シート（２）が水溶性で破れ易いが、補強網体（３）を間に入れたことにより、極めて破れ難く、柔軟性に富み、且つ、表紙シート（１），裏紙シート（２）及び補強網体（３）が水溶性であるため、使用後にそのまま全部がトイレに流して捨てることができる。 In the water-soluble reinforcing paper of the present invention, the cover sheet (1) and the backing paper sheet (2) are water-soluble and easily torn. Since it is rich and the cover sheet (1), the back sheet (2), and the reinforcing net (3) are water-soluble, they can all be flushed and discarded after use.
また、表紙シート（１）及び裏紙シート（２）が、複数枚の水溶性紙シートを水溶性接着剤で接着して重層にしたことにより、使用時に排泄物の処理等ですぐに破れるのを防止でき、且つ、各シート（１），（２）が厚くなっても、トイレに流すと直ちに重層構造がほどけて水に溶解され流し捨てることができ、トイレを詰まらせる心配もない。 In addition, the cover sheet (1) and the backing sheet (2) can be easily broken by excrement disposal at the time of use because a plurality of water-soluble paper sheets are bonded with a water-soluble adhesive to form a multilayer. Even if the sheets (1) and (2) become thicker, the multilayer structure can be unwound immediately after flowing into the toilet, dissolved in water and thrown away, and there is no worry of clogging the toilet.
更に、補強網体（３）が、水溶性の紙紐で網目状に形成したことにより、紙の強度が全方向にわたって均一に得られ、どの方向からも破れることがなく、使用時に方向性を考える必要がないので、本発明の強化紙を使用目的の物に加工するにも成形が容易となる。この成形においても、表紙シート（１）及び裏紙シート（２）が水溶性で薄いため、これらシート（１），（２）のみでは成形した形状を保持できずにくずれ易いが、補強網体により成形した形状が保て安定する。 Furthermore, since the reinforcing mesh (3) is formed in a mesh shape with a water-soluble paper string, the strength of the paper is obtained uniformly in all directions, and it is not torn from any direction, and the directionality during use is improved. Since there is no need to think about it, molding becomes easy even when the reinforced paper of the present invention is processed into an intended product. In this molding as well, the cover sheet (1) and the backing sheet (2) are water-soluble and thin, so that these sheets (1) and (2) alone cannot retain the molded shape and are easily broken. The molded shape is maintained and stabilized.
以下、本発明の実施形態につき、図を基に説明する。図１に示すように、（１)は水溶性又は水解性の紙を使用した表紙シートであり、（２）は表紙シート（１）と同様な紙質の裏紙シートであり、この表紙シート（１）及び裏紙シート（２）は、木材パルプ繊維，非木材系パルプ繊維，レーヨン繊維，ポリエステル繊維等を原料繊維として湿式法や乾式法等の常法により製造されるものであり、特にはトイレットペーパーと同様な材質のものが安価であり好ましい。 Hereinafter, embodiments of the present invention will be described with reference to the drawings. As shown in FIG. 1, (1) is a cover sheet using water-soluble or water-degradable paper, (2) is a paper backing sheet similar to the cover sheet (1), and this cover sheet ( 1) and the backing paper sheet (2) are produced by a conventional method such as a wet method or a dry method using wood pulp fibers, non-wood pulp fibers, rayon fibers, polyester fibers, etc. as raw fibers, A material similar to toilet paper is preferable because it is inexpensive.
（３）は表紙シート（１）と裏紙シート（２）を重ねた中間に入れて補強するための補強網体であり、これは水溶性又は水解性の紙で紙紐を作り、この紙紐を使用して網目状に並べるか又は編んで成形したものである。更に、この紙紐を作るには、主としてセルロース系の水溶性又は水解性材料、例えばポリビニルアルコール，ポリアクリル酸塩共重合体，カルボキシル化セルロース等の水溶性材料等から成り、これらを使用して、複数本の繊維を撚り合せた糸状あるいはフィルムを切断したリボン状のものを撚って紐にして使用すればよく、特に好ましくはトイレットペーパーの紙リボンを撚った紙紐がよい。 (3) is a reinforcing mesh for reinforcing the cover sheet (1) and the backing sheet (2) by putting them in the middle, and this is a paper string made of water-soluble or water-degradable paper. It is formed by arranging in a mesh or using a string. Furthermore, to make this paper string, it consists mainly of water-soluble or water-degradable materials such as cellulosic water-soluble materials such as polyvinyl alcohol, polyacrylate copolymers, carboxylated cellulose, etc. A string formed by twisting a plurality of fibers or a ribbon formed by cutting a film may be used as a string, and a paper string formed by twisting a paper ribbon of toilet paper is particularly preferable.
また、補強網体（３）の網目形状にとしては、例えば図３（ａ）に示す格子状の他に図３（ｂ）の菱形でもよく、要するに網目状に並べるか又は編んで形成したものならばよい。 Further, the mesh shape of the reinforcing mesh body (3) may be, for example, the diamond shape shown in FIG. 3 (b) in addition to the lattice shape shown in FIG. 3 (a). If so.
これら表紙シート（１）と裏紙シート（２）は、図２に示すように重ねて貼り合せるが、この際に両紙シート（１），（２）間に補強網体（３）を入れて貼り合される。この貼り合せる際に使用する接着剤は水溶性のものである。また、両紙シート（１），（２）は図２（ａ）の如く各１枚で貼り合せてもよいが、図２（ｂ）のように、両紙シート（１），（２）がそれぞれ複数枚に重ねたものを使用してもよく、この場合には、柔軟性を保ちつつ、１枚のものに比べより強度も高く使用中に水分の吸収性が向上し使用し易くなる。 These cover sheet (1) and backing paper sheet (2) are overlapped and bonded as shown in FIG. 2, but at this time, a reinforcing net (3) is inserted between both paper sheets (1) and (2). Pasted together. The adhesive used for bonding is water-soluble. Further, both the paper sheets (1) and (2) may be bonded together as shown in FIG. 2 (a), but the both paper sheets (1) and (2) are respectively attached as shown in FIG. 2 (b). A plurality of sheets may be used. In this case, while maintaining flexibility, the strength is higher than that of a single sheet, and the moisture absorption is improved during use, so that it is easy to use.
このように、表紙シート（１）と裏紙シート（２）とを貼着するのに、補強網体（３）を中に挟んで貼着した水溶性強化紙においては、この強化紙を基に、種々の使用目的に応じた形状に成形できる。つまり、水溶性の表紙シート（１）及び裏紙シート（２）のみの場合には、素材に腰がなく、一定の形状を保持させることが難しいが、紙紐で編んだ補強網体（３）により、成形した形状を保持させることができるのである。従って、例えば犬の排泄物を収納用の皿状や箱状にも成形でき便利である。 In this way, in the case of the water-soluble reinforced paper in which the cover sheet (1) and the backing paper sheet (2) are adhered to each other with the reinforcing net (3) sandwiched therebetween, Furthermore, it can be formed into a shape corresponding to various purposes. That is, in the case of only the water-soluble cover sheet (1) and the back paper sheet (2), the material is not stiff and it is difficult to maintain a certain shape, but the reinforcing net (3 ), The molded shape can be held. Therefore, for example, dog excrement can be conveniently formed into a storage dish or box.
