Description
【０００１】[0001]
本考案は多層構造シートに関し、とくにシーツ、マット、座布団などの体の下 に敷いて用いるシートに関する。 The present invention relates to a multi-layered sheet, and particularly to a sheet to be laid under a body such as a sheet, a mat, and a cushion.
【０００２】[0002]
人が眠る場合や座る場合に、体を面で支えるよりも、多数の点で支える方が、 血行障害を防止し、皮膚局部にかかる体重圧のストレスや炎症を抑えられること が知られている。例えば、寝た状態を長くとり続ける病人や老人の場合、皮膚の 潰瘍や褥瘡などの炎症を起こすことがあるが、多数の点で支えられる寝具を使用 するとこの様な炎症が生じにくい。従来、多数の点で支える寝具としては、マッ トレスの内部に凸部を多数形成した発泡体やゴムシートを収納したものが知られ ているが、発泡体の場合には長期の使用の内にへたってしまって効果がなくなる という問題があり、ゴムシートの場合には感触が固く体に馴染みにくいという問 題があった。また、いずれもマットレス内に収納されているため、取り替えが困 難であるという欠点もあった。 It is known that, when a person sleeps or sits down, supporting the body in multiple points rather than supporting it in a flat surface prevents blood circulation disorders and suppresses body weight pressure stress and inflammation on the local skin. . For example, in the case of a sick person or an elderly person who keeps sleeping for a long time, inflammation such as skin ulcer or pressure ulcer may occur, but when using bedding that supports many points, such inflammation is less likely to occur. Conventionally, as bedding that supports a number of points, it is known that a mattress contains a foam or rubber sheet with a large number of protrusions formed inside it. There is a problem that the effect becomes tired and loses its effect, and in the case of a rubber sheet, there is a problem that the feel is hard and it is difficult for the body to adapt. In addition, all of them are stored in the mattress, which makes it difficult to replace them.
【０００３】 本考案者は上記従来技術の欠点を解決するために、実開昭６２−１８２７２５ 号などに開示される平面フィルムと突起フィルムとが接合一体化された空気内包 シート素材を使用し、この表裏に不織布などの繊維質シートを積層した多層構造 シートを検討した。このシートの場合、凸部が空気の内包されたフィルムで構成 されるので感触がソフトであり、またマットレスのような大掛かりな構造をとら ないので、簡便に取り替えることができるという利点を有する。しかしながら、 このシートの場合にも人体などの重量が長期に渡って加わることにより、フィル ムの破裂や内包された空気の漏れによりへたりが生じることがあった。しかも、 空気を封入した凸部で重量を支えるため、凸部が平に変形しやすく、点で支える という効果も失われやすかった。In order to solve the above-mentioned drawbacks of the prior art, the inventor of the present invention uses an air-encapsulating sheet material in which a flat film and a projection film, which are disclosed in Japanese Utility Model Laid-Open No. 62-182725, are integrally joined. We examined a multi-layer structure sheet in which fibrous sheets such as non-woven fabric were laminated on both sides. This sheet has an advantage that it can be easily replaced because it does not have a large-scale structure such as a mattress because it has a soft feel because the convex portion is made of a film containing air. However, even in the case of this sheet, the weight of the human body or the like is added for a long period of time, and thus the film may be ruptured due to the rupture of the film or leakage of the enclosed air. Moreover, since the convex portion that encloses the air supports the weight, the convex portion is easily deformed into a flat shape, and the effect of supporting it at points is easy to be lost.

本考案は上記従来の技術の欠点を解消すべくなされたものであり、人体などを 多数の点で支えることができ、へたりにくく、感触がよく、簡便に取り扱える多 層構造シートを提供することを目的とする。 The present invention has been made to solve the above-mentioned drawbacks of the conventional technology, and provides a multi-layered sheet that can support the human body in many points, is hard to be flat, has a good feel, and can be handled easily. With the goal.

すなわち、本考案は平面フィルムと突起フィルムとを接合一体化した素材の表 裏面に、繊維質シートを積層したシートにおいて、該素材の平面フィルムと突起 フィルムによって囲まれる空間に粉粒体を充填せしめたことを特徴とする多層構 造シートに関する。 That is, the present invention is a sheet in which a fibrous sheet is laminated on the front and back surfaces of a material in which a flat film and a projection film are bonded and integrated, and a space surrounded by the flat film and the projection film of the material is filled with powder particles. The present invention relates to a multi-layered structure sheet.
【０００６】 以下、図面を用いて本考案を説明する。図１は本考案の多層構造シートの一例 を示す断面模型図であり、図２、図３は各々本考案の多層構造シートの他の例を 示す断面模型図である。The present invention will be described below with reference to the drawings. FIG. 1 is a sectional model view showing an example of the multilayer structure sheet of the present invention, and FIGS. 2 and 3 are sectional model views showing other examples of the multilayer structure sheet of the present invention.
【０００７】 本考案においては、平面フィルム１と突起フィルム２とを接合一体化した素材 を使用する。平面フィルム１及び突起フィルム２には、ポリエチレン系樹脂、ポ リプロピレン系樹脂、ポリアミド系樹脂、ポリエステル系樹脂、ポリスチレン系 樹脂、シリコーン系樹脂、ポリウレタン系樹脂、セルロース系樹脂などの樹脂か らなるフィルムが好適に用いられる。フィルムは単層であっても多層であっても よく、また、平面フィルム１と突起フィルム２とは同じフィルムであっても異な るフィルムであってもよい。なお、後述する粉粒体３に、吸湿性、芳香性、抗菌 性などの機能性を有するものを用いる場合には、フィルムには気体の透過が物理 的又は化学的に可能なものを使用することが望ましい。一方、とくに弾性やソフ トな感触が望まれる場合には、粉粒体と共に気体を充填するとよく、この場合フ ィルムには非通気性のものを選択することが望ましい。In the present invention, a material in which the flat film 1 and the protrusion film 2 are joined and integrated is used. The flat film 1 and the projection film 2 are films made of resins such as polyethylene resin, polypropylene resin, polyamide resin, polyester resin, polystyrene resin, silicone resin, polyurethane resin, and cellulose resin. Is preferably used. The film may be a single layer or a multilayer, and the flat film 1 and the projection film 2 may be the same film or different films. In addition, when a powder or granular material 3 to be described later is used that has functionality such as hygroscopicity, fragrance and antibacterial property, a film that physically or chemically allows gas permeation is used. Is desirable. On the other hand, when elasticity and soft feeling are desired, it is preferable to fill the gas with the powder and granular material. In this case, it is desirable to select a non-breathable film.
【０００８】 突起フィルム２には、円柱状、四角柱状などの柱状突起、または半球状、かま ぼこ状などのドーム状突起などが適宜の配置で設けられているものが好適に使用 される。突起フィルム２はフィルム形成の際に突起に対応する形状を有する型を 用いて作成してもよいし、一旦平面フィルムを形成した後に型を用いて熱成形し てもよい。The protrusion film 2 is preferably provided with columnar protrusions such as columnar and quadrangular prisms, or dome-shaped protrusions such as hemispherical and semicylindrical shapes in an appropriate arrangement. The protrusion film 2 may be formed by using a mold having a shape corresponding to the protrusion when forming the film, or may be thermoformed by using the mold after forming the flat film once.
【０００９】 平面フィルム１と突起フィルム２とは接着剤による接着により、又はフィルム の熱融着により接合一体化される。後者の場合には、平面フィルム１又は突起フ ィルム２の少なくとも一方の接合面に熱融着性フィルムを使用する。接合された 素材は、通常は図１のように平面フィルム１が裏面側に、突起フィルム２が表面 側となるように用いられるが、図２のように突起フィルム２の両面に平面フィル ム１１、１２を積層してもよく、また図３のように平面フィルム１の両面に突起 フィルム２１、２２を積層してもよい。これらの場合には、表裏の区別なく使用 することができる。The flat film 1 and the projection film 2 are joined and integrated by adhesion with an adhesive or by heat fusion of the films. In the latter case, a heat-fusible film is used on at least one joint surface of the flat film 1 or the projecting film 2. The joined materials are usually used so that the flat film 1 is on the back side and the projection film 2 is on the front surface as shown in FIG. 1. However, as shown in FIG. , 12 may be laminated, or the protruding films 21 and 22 may be laminated on both surfaces of the flat film 1 as shown in FIG. In these cases, it can be used without distinction between the front and back.
【００１０】 上記素材の平面フィルム１と突起フィルム２とで囲まれる空間には、粉粒体３ が充填される。本考案の多層構造シートにおいては、この充填された粉粒体３が 人体などのシートに加わる重みを支えるため、突起フィルム２の形状が大きく変 形せず、シートのへたりが生じにくいので、点で支える効果が持続できる。また 、粉粒体３は充填されていてもある程度の移動は可能であるため、シートに接触 する人体の形状に合わせて多少変形できるので、体に馴染みやすく感触もよい。 とくに、発泡スチロールのビーズなどの多孔体や中空体を充填したものは、圧縮 弾性を有するのでソフトな感触のシートを形成できるのでよい。また、上記の空 間に粉粒体３とともに空気などの気体を充填してもソフトな感触のシートが得ら れる。ただし、後者の場合には、空気が抜けると突起部の形状の変化が大きくな るので、非通気性のフィルムを使用することが望ましい。The space surrounded by the flat film 1 and the projection film 2 made of the above-mentioned material is filled with powder particles 3. In the multi-layered sheet of the present invention, since the filled granular material 3 supports the weight applied to the sheet such as a human body, the shape of the projection film 2 is not largely changed, and the sheet is less likely to be settled. The effect of supporting by points can be sustained. In addition, since the granular material 3 can be moved to some extent even when it is filled, it can be deformed to some extent according to the shape of the human body that comes into contact with the sheet, and it is easy to fit into the body and feels good. In particular, a material filled with a porous body or a hollow body such as styrofoam beads is preferable because it has a compression elasticity and can form a soft-feeling sheet. In addition, a sheet having a soft feel can be obtained even when the air is filled with a gas such as air together with the powdery particles 3. However, in the latter case, it is desirable to use a non-breathable film, because the shape of the protrusion changes greatly when air escapes.
【００１１】 本考案の粉粒体３には、例えばポリスチレン、ポリウレタン、シリコーンなど の樹脂または発泡体をビーズ状、粒状に成形したものや、砂、もみがら、コルク などの粒体などの他に、活性炭などの脱臭剤、シリカゲルなどの吸湿剤、金、銀 、銅などの金属粉末、抗菌性ゼオライトなどの抗菌剤などからなる機能性粉体な どが好適に使用できる。これらは単独もしくは混合して用いられるが、とくに機 能性粉体を充填する場合には、機能が有効に働くように、平面フィルム１又は突 起フィルム２の少なくとも一方を物理的又は化学的に気体を通過させるフィルム で構成することが望ましい。The powder and granules 3 of the present invention include, for example, resin or foam such as polystyrene, polyurethane and silicone formed into beads or granules, and particles such as sand, chaff and cork. Functional powders such as deodorants such as activated carbon, hygroscopic agents such as silica gel, metal powders such as gold, silver and copper, and antibacterial agents such as antibacterial zeolite can be preferably used. These may be used alone or as a mixture, and particularly when the functional powder is filled, at least one of the flat film 1 and the protruding film 2 is physically or chemically so that the function works effectively. It is desirable to use a film that allows gas to pass through.
【００１２】 粉粒体３を平面フィルム１と突起フィルム２とで囲まれる空間に充填する方法 としては、突起フィルム２を突起が下に向くように置き、この突起内に適量の粉 粒体３を入れた後に、平面フィルム１を積層し、突起フィルム２と接合一体化す る方法がある。なお、粉粒体３を入れる時に突起フィルム２を振動させながら入 れると、粉粒体３が平面フィルム１と突起フィルム２との接合面に残らず、効率 よく突起内に充填されるのでよい。As a method of filling the space surrounded by the flat film 1 and the projection film 2 with the powder particles 3, the projection film 2 is placed with the projections facing downward, and an appropriate amount of the powder particles 3 is placed in the projections. After putting in, there is a method of laminating the flat film 1 and joining and integrating with the projection film 2. It should be noted that when the powder particles 3 are put in while vibrating the projection film 2, the powder particles 3 do not remain on the joint surface between the flat film 1 and the projection film 2 and can be efficiently filled in the projections. .
【００１３】 平面フィルム１と突起フィルム２とを接合一体化した素材の表裏には、繊維質 シート４、５が積層される。繊維質シート４、５には、不織布、編織布、紙など を単独または複合したシートが使用される。とくに、突起フィルム２に積層され る表面側繊維質シート４は人体と接触する面であるので、汗などの体液や水分が 繊維質シート表面に残らないようにすることが望ましい。このため、表面側繊維 質シート４には、表面に水分が付着しにくいように繊維質シートの表面を撥水加 工したものを用いたり、水分がシート内部に速やかに吸収されるように表面が撥 水性又は疎水性で内部を親水性にした繊維質シートを用いることが望ましい。例 えば、このような繊維質シート４としては、親水性繊維の上層と疎水性繊維の下 層とを有する水流絡合不織布や、表面を撥水加工した親水性繊維からなる水流絡 合不織布などがある。一方、平面フィルム１に積層される裏面側繊維質シート５ はとくに限定されないが、多層構造シートが容易に滑らないようにできるものや 、多層構造シートに強度の付与できるものが望ましく、例えばスパンボンド不織 布などがとくに適している。Fibrous sheets 4 and 5 are laminated on the front and back of a material in which the flat film 1 and the projection film 2 are integrally joined. As the fibrous sheets 4 and 5, sheets made of non-woven fabric, knitted fabric, paper or the like alone or in combination are used. In particular, since the surface side fibrous sheet 4 laminated on the protrusion film 2 is the surface that comes into contact with the human body, it is desirable that body fluid such as sweat and moisture do not remain on the surface of the fibrous sheet. For this reason, as the front side fibrous sheet 4, a fibrous sheet whose surface is treated to be water-repellent so that water does not easily adhere to the surface side, or a surface which allows water to be quickly absorbed inside the sheet is used. It is desirable to use a fibrous sheet which is water-repellent or hydrophobic and whose inside is hydrophilic. For example, such a fibrous sheet 4 includes a hydroentangled non-woven fabric having an upper layer of hydrophilic fibers and a lower layer of hydrophobic fibers, a hydroentangled non-woven fabric made of hydrophilic fibers having a water-repellent surface, and the like. There is. On the other hand, the back side fibrous sheet 5 to be laminated on the flat film 1 is not particularly limited, but it is desirable that the multilayer structure sheet can be prevented from slipping easily and that the multilayer structure sheet can be imparted with strength, for example, spun bond. Nonwoven fabrics are especially suitable.
【００１４】 上記フィルム素材と繊維質シートとは、接着剤、接着フィルムなどを用いて接 着してもよく、フィルム素材又は繊維質シートの構成繊維に熱融着性のものを使 用して接着してもよいが、場合によっては、表裏の繊維質シートどうしを袋状に 接合し、その内部にフィルム素材を収納するようにしてもよい。このように、フ ィルム素材の表裏両面に繊維質シートを積層することによって、シーツやマット などの下敷シートの代用として多層構造シートを用いることが可能になるので、 点で人体を支える機構をマットレスなどに組込む大掛かりな構造としなくても簡 便に導入でき、しかも取り替えも簡単に行える。The film material and the fibrous sheet may be adhered to each other by using an adhesive, an adhesive film or the like, and the constituent fibers of the film material or the fibrous sheet may be heat-meltable. It may be bonded, but in some cases, the fibrous sheets on the front and back may be joined in a bag shape, and the film material may be housed inside. By laminating the fibrous sheets on both the front and back sides of the film material in this way, it becomes possible to use a multi-layer structure sheet as a substitute for an underlay sheet such as a sheet or a mat. It can be installed easily without the need for a large-scale structure that can be incorporated into a device, and can be easily replaced.
【００１５】 なお、図３に示すように、多層構造シートを表裏の区別なく使用できるように する場合には、裏面側繊維質シート５は用いず、表面側繊維質シート４１、４２ を両面に配してもよい。As shown in FIG. 3, when the multilayer structure sheet can be used without distinction between the front and back sides, the back side fibrous sheet 5 is not used and the front side fibrous sheets 41 and 42 are provided on both sides. You may distribute it.
【００１６】[0016]
本考案の多層構造シートは、平面フィルムと突起フィルムとによって囲まれる 空間に粉粒体が充填されているので、突起部が人体などの荷重を受けても大きく 変形せず、へたることもないので、人体などを多数の点で支える効果を長期に渡 って利用することができる。また、粉粒体は充填されていても人体の動きに合わ せてある程度移動できるので、体に馴染みやすく感触もよい。更に、本考案の多 層構造シートは表裏に繊維質シートが積層されているので、体の下に敷くシーツ 、マット、座布団などの代用品として使用でき、取り扱いが簡便で、大掛かりな 構造をとることなく、人体などを多数の点で支える機構を利用できる。 The multilayer structure sheet of the present invention is filled with powder particles in the space surrounded by the flat film and the projection film, so that the projection does not deform significantly even when subjected to a load such as a human body, and does not sag. Therefore, the effect of supporting the human body in many points can be used for a long period of time. Further, even if the granular material is filled, it can be moved to some extent in accordance with the movement of the human body, so that it is easy to fit into the body and feels good. Furthermore, since the multi-layer structure sheet of the present invention has fibrous sheets laminated on the front and back, it can be used as a substitute for sheets, mats, cushions, etc. laid under the body, and is easy to handle and has a large-scale structure. Without having to do so, a mechanism that supports the human body at many points can be used.
