Description

本発明は生理用ナプキン、おむつ、尿失禁パッド、パンティライナーなど吸収製品に関するものである。   The present invention relates to absorbent products such as sanitary napkins, diapers, urinary incontinence pads, panty liners and the like.

一般に吸収製品は大きく上部シート、下部シート及び上部シートと下部シートとの間に位置した吸収コアからなっている。このうち、上部シートは吸収コア上に位置する中央カバーと中央カバーの側方向に長く位置する側方向カバーからなる。中央カバーは液体を吸収して吸収コアに伝達する役割を遂行し、側方向カバーは軟らかい着用感を提供すると同時に液体の漏れを防止し、より大きい安定感を与える役割を遂行する。
従来の吸収製品では、TABCW, TBCW, SBWなどの不織布で側方向カバーが形成された。TBCW, SBWなどの不織布では、個別的なファイバの結合のための規則的な結合パターンが外部に表れていた。このような単調な結合パターンは、使用者に審美感を提供する面において非常に制約的であった。 In general, the absorbent product is mainly composed of an upper sheet, a lower sheet and an absorbent core positioned between the upper sheet and the lower sheet. Among these, an upper sheet | seat consists of a side cover located long in the side direction of a center cover located on an absorption core, and a center cover. The central cover serves to absorb and transmit the liquid to the absorbent core, and the side cover serves to provide a soft wearing feeling while at the same time preventing liquid leakage and providing a greater sense of stability.
In conventional absorbent products, the side cover is formed of non-woven fabric such as TABCW, TBCW, SBW. In non-woven fabrics such as TBCW and SBW, a regular coupling pattern for coupling individual fibers appeared outside. Such a monotonous coupling pattern is very restrictive in providing aesthetics to the user.

本発明者は生理用ナプキン、おむつ、尿失禁パッド、パンティライナーなどの吸収製品において、人体から排出された液体を吸収する基本的な機能だけでなく、製品自体の形状や製品に刻まれた文様などを通じて使用者に美しさを感じさせ、心理的安定感を与えるなどの心理的側面での機能も非常に重要であるという点に注目した。本発明の目的は、従来の吸収製品の側方向カバーが単に不織布ファイバの結合パターンのみを外部に露出させ、心理的側面での機能を十分に行われなかった問題を克服し、側方向カバーに美しい文様を刻み入れ、吸収製品全体の美的価値を高めるものである。   The present inventor has not only the basic function of absorbing liquid discharged from the human body in absorbent products such as sanitary napkins, diapers, urinary incontinence pads, panty liners, but also the shape of the product itself and the patterns engraved on the product. We paid attention to the fact that psychological functions such as giving users a sense of beauty and giving them psychological stability are also very important. The object of the present invention is to overcome the problem that the side cover of the conventional absorbent product simply exposes the non-woven fiber bonding pattern to the outside, and the function of the psychological aspect is not sufficiently performed. Engrave beautiful patterns and enhance the aesthetic value of the entire absorbent product.

本発明の吸収製品は、中央カバー、中央カバーの左右側縁部に位置し、中央カバーに一部重畳して接着剤により中央カバーに結合する側方向カバー、中央カバーと、側方向カバーが重畳した部位とクリンプ熱封止方式により結合する下部シート、中央カバーと下部シートとの間の空間に位置する吸収コアを備える。本発明の側方向カバーは不織布で形成され、側方向カバーの材料である不織布は複数の個別的な文様からなる文様を含む。本発明の側方向カバーの文様は、熱圧着エンボシング方式により形成され、熱圧着エンボシング方式により文様が刻まれるとき、圧縮ローラの回転方向に個別的な文様が互いに対して重畳して刻まれる。
また、本発明の吸収製品は、中央カバーと側方向カバーが別個の構成要素でなく、一つの構成要素の場合も可能である。この場合には、本発明の吸収製品は上部シート、縁部部分が上部シートと結合した下部シート及び上部シートと下部シートとの間の空間に位置する吸収コアを備える。上部シートは熱圧着エンボシング方式により形成された複数の個別的な文様からなる文様を含み、熱圧着エンボシング方式により文様が刻まれると、圧縮ローラの回転方向に個別的な文様が互いに対して重畳する。熱圧着方式により文様を具現するとき、不織布自体では厚さが高くて密度が低いが、熱圧着を用いて文様を刻む時に熱圧着ローラが不織布に付く文様部分では、圧着、熱変形によりほぼフィルム化が進行され、厚さが薄くなり密度が非常に高くなる。文様がある部分とない部分とのこのような密度の差により、密度が高い部分が文様として認識できるようになる。密度が低い部分は厚さが厚いが、この時の厚さは0.3mm乃至2mmが望ましく、密度が高い部分は厚さが薄いが、この時の厚さは0.03mm乃至1mmが望ましい。本発明の上部シートが単一の構成要素で形成されるとき、熱圧着エンボシングにより形成される文様が上部シート全体にかけて形成されることもでき、上部シートのうち側面部分にのみ形成されることができる。下部シートと結合し、吸収コアを取り囲む上部シートの部分が中央カバーと側方向カバーの二つの構成要素で形成される場合と単一の構成要素である上部シートで形成される場合において、エンボシング処理方式、エンボシング処理される材質の特性、刻まれる文様の特性、下部シートとの結合方式などはいずれも同一である。 The absorbent product according to the present invention is located on the left and right side edges of the center cover, the center cover, and the side cover, the center cover, and the side cover that are partially overlapped with the center cover and joined to the center cover by an adhesive. The lower sheet | seat couple | bonded with the crimped part by the crimp heat sealing system, and the absorption core located in the space between a center cover and a lower sheet | seat are provided. The lateral cover of the present invention is formed of a nonwoven fabric, and the nonwoven fabric that is the material of the lateral cover includes a pattern composed of a plurality of individual patterns. The pattern of the side cover of the present invention is formed by a thermocompression embossing system, and when a pattern is engraved by the thermocompression embossing system, individual patterns are engraved on each other in the rotation direction of the compression roller.
In the absorbent product of the present invention, the central cover and the side cover are not separate components but can be a single component. In this case, the absorbent product of the present invention comprises an upper sheet, a lower sheet whose edge portion is joined to the upper sheet, and an absorbent core located in the space between the upper sheet and the lower sheet. The upper sheet includes a pattern composed of a plurality of individual patterns formed by the thermocompression embossing method. When a pattern is engraved by the thermocompression embossing method, the individual patterns are superimposed on each other in the rotation direction of the compression roller. . When embodying the pattern by thermocompression bonding, the non-woven fabric itself is thick and low in density, but the pattern where the thermocompression roller is attached to the non-woven fabric when engraving the pattern using thermocompression bonding is almost a film due to crimping and thermal deformation. As the process proceeds, the thickness becomes thinner and the density becomes very high. Due to the difference in density between the part with the pattern and the part without the pattern, the part with high density can be recognized as the pattern. The low density portion is thick, but the thickness at this time is preferably 0.3 mm to 2 mm, and the high density portion is thin, but the thickness at this time is preferably 0.03 mm to 1 mm. When the upper sheet of the present invention is formed of a single component, the pattern formed by thermocompression embossing may be formed over the entire upper sheet, and may be formed only on the side surface portion of the upper sheet. it can. The embossing process when the part of the upper sheet that is joined to the lower sheet and surrounds the absorbent core is formed by two components, the central cover and the side cover, and the upper sheet that is a single component The method, the characteristics of the material to be embossed, the characteristics of the pattern to be engraved, the method of joining to the lower sheet, etc. are all the same.

本発明によると、側方向カバーに美しい文様を刻み入れ、吸収製品全体の美的価値を高めることができる。また、側方向カバーの材料に用いられる不織布上に不規則的な配列のデザインをエンボシング処理により刻み入れ、この不織布を側方向カバーとして用いるので、左側側方向カバーと右側側方向カバーのデザインが互いに同一でなく、1つのパッケージ内でも隣接吸収製品間に互いに異なるデザインを備えるようになる。このような点は、使用者に与える審美感を一層高めることができるようになる。一方、文様を刻むにおいても、個別の文様が互いに重畳するようにすることにより、熱圧着エンボシング工程で側方向カバーの材質になる不織布上に、より均等に文様を刻み入れることができる。また、体液の量が多い場合には、主吸収層の縁部を越えて広がることがあるが、中央カバー及び側方向カバーの重畳部位で、下部シートと熱封止を適用することにより体液の広がりが側方向カバーまで拡大されることを防げるようになる。   According to the present invention, it is possible to engrave a beautiful pattern on the side cover and increase the aesthetic value of the entire absorbent product. In addition, an irregular array design is engraved on the nonwoven fabric used for the material of the side cover by embossing, and this nonwoven fabric is used as the side cover, so the design of the left side cover and the right side cover are mutually It is not the same, and it will have different designs between adjacent absorbent products within one package. Such a point can further enhance the aesthetic feeling given to the user. On the other hand, even when patterns are engraved, the patterns can be engraved more evenly on the nonwoven fabric that becomes the material of the side cover in the thermocompression embossing process by making the individual patterns overlap each other. In addition, when the amount of body fluid is large, it may spread beyond the edge of the main absorbent layer, but by applying the lower sheet and heat sealing at the overlapping part of the center cover and the side cover, The spread can be prevented from expanding to the side cover.

以下で、図2をまず参照して本発明による吸収製品の一実施の形態について説明する。本発明の権利範囲は、以下に説明される実施の形態により制限されるのではない。
図2は本発明の吸収製品の断面図である。吸収製品は大きく、中央カバー(1)、側方向カバー(2)、下部シート(3)、吸収コア(4)からなる。中央カバー(1)の縁部付近で側方向カバー(2)は中央カバー(1)上に一部重畳する。この重畳部位に接着剤が塗布されることにより、中央カバー(1)と側方向カバー(2)が結合する。接着剤を塗布するにおいては、ビード(BEAD)やシムコーティング(SHIM COATING)方法を用いることが望ましく、塗布される接着剤の幅は0.5mm乃至5mmが望ましい。接着剤の種類としては、一般に用いられる接着剤を用いることもできるが、溶液流れ遮断の側面では、疎水性接着剤を用いることが望ましい。接着剤により結合した中央カバー(1)と側方向カバー(2)の重畳部位は、クリンプ(CRIMP)熱封止方式により下部シート(3)に結合する。吸収コア(4)は中央カバー(1)と下部シート(3)により囲まれた空間内に位置する。中央カバー(1)は穿孔フィルム、不織布または不織布とフィルムを積層することにより形成された物質で製作できる。不織布としてはTABCW(Through Air Bonded Carded Web), TBCW(Thermal Bonded Carded Web), SBW(Spun Bonded Web)またはスパンレース(Spunlace)が用いられる。どの材質で形成されるとしても、中央カバー(1)は液体を透過させる性質を有しなければならない。人体から排出された液体が吸収コア(4)で吸収されるためには、中央カバー(1)を必ず通過しなければならないためである。側方向カバー(2)の材質としては、TABCW, TBCW, SBW, スパンレースなどの不織布または不織布とフィルムの積層物が用いられる。側方向カバー(2)としては、疎水性材質と親水性材質がいずれも用いられるが、親水性材質を用いることがより望ましい。側方向カバー(2)には、審美感を呼び起こす文様が位置する。これについては図1を参照し、より詳細に説明する。
側方向カバーを形成する材質上の文様は、熱圧着エンボシング方式により形成される。図1に示された実施の形態では、花状の文様を有する側方向カバーが示されている。側方向カバーは、上部カバーと結合する前に熱圧着エンボシング方式により多様な文様を有することになる。側方向カバーの材料を熱圧着エンボシング処理するときに重要な点はエンボシングローラ(図示省略)の回転方向に個別の文様が重畳しているという点がある。図1のB部分を見ると、垂直方向に個別の文様が重畳しているという点を分かる。図1のA部分とC部分には重畳していない個別の文様があるが、これはこの部分に刻まれた文様と重畳する文様を有する上部または下部部分が切られたためである。もし、このように個別の文様を互いに重畳するようにしなければ、熱圧着エンボシング工程でエンボシングローラに刻まれた前後の文様間に空き空間が生じることになる。空き空間とは、ローラにより刻まれる文様のうち、(時間的に)前に刻まれる文様と後に刻まれる文様との間に余白があるということを意味する。このような空き空間により、刻む文様がある部分と文様がない部分との間で高さの差が発生し、これにより個別文様の最初に始まる部分では鮮明度が高く、終わりの部分では鮮明度が落ち、一個の個別文様内でも鮮明度の偏差が発生することがある。側方向カバーを形成する不織布は基本的に親水性材質であり、約10gsm乃至100gsmの坪量を有し、太さが10デニール(denier)、良好では3デニール以下の細かい繊維で構成される。様々な文様を熱圧着エンボシング方式により不織布上に刻む実験を反復的に実行した結果、曲線のみからなる文様または直線と曲線を適切に混合した文様が吸収製品と充分に調和し、審美感を効果的に呼び起こすという事実を発見した。また、使用者が文様を容易に認識することができるようにするためには、直線と曲線の線の太さが0.2mm以上、3mm以下の場合が有利であるという事実を発見した。側方向カバーを形成する不織布は、身体につく部分とその反対面がファジーな(fuzzy)面とスムーズな(smooth)面に区分できたり、または区分ができないこともあるが、区分できる場合には、スムーズな面が着用者の身体に接触するように配置することが望ましい。これはエンボシング処理された文様の鮮明度がファジーな面よりスムーズな面で優れて具現され、使用者により容易に認識できるためである。 In the following, an embodiment of an absorbent product according to the invention will be described with reference first to FIG. The scope of rights of the present invention is not limited by the embodiments described below.
FIG. 2 is a cross-sectional view of the absorbent product of the present invention. The absorbent product is large and consists of a central cover (1), a side cover (2), a lower sheet (3), and an absorbent core (4). The side cover (2) partially overlaps the central cover (1) near the edge of the central cover (1). By applying an adhesive to the overlapping portion, the central cover (1) and the side cover (2) are coupled. In applying the adhesive, it is preferable to use a bead (BEAD) or shim coating (SHIM COATING) method, and the width of the applied adhesive is preferably 0.5 mm to 5 mm. As the type of adhesive, a commonly used adhesive can be used, but it is desirable to use a hydrophobic adhesive in terms of blocking the solution flow. The overlapping portion of the central cover (1) and the side cover (2) bonded by the adhesive is bonded to the lower sheet (3) by a crimp (CRIMP) heat sealing method. The absorbent core (4) is located in a space surrounded by the central cover (1) and the lower sheet (3). The central cover (1) can be made of a perforated film, a nonwoven fabric or a material formed by laminating a nonwoven fabric and a film. As the nonwoven fabric, TABCW (Through Air Bonded Carded Web), TBCW (Thermal Bonded Carded Web), SBW (Spun Bonded Web), or Spunlace is used. Regardless of the material used, the central cover (1) must have the property of allowing liquid to pass through. This is because the liquid discharged from the human body must pass through the central cover (1) in order to be absorbed by the absorption core (4). As the material of the side cover (2), a non-woven fabric such as TABCW, TBCW, SBW, spunlace or a laminate of non-woven fabric and film is used. As the side cover (2), both a hydrophobic material and a hydrophilic material are used, but it is more preferable to use a hydrophilic material. The side cover (2) has a pattern that evokes aesthetics. This will be described in more detail with reference to FIG.
The pattern on the material forming the side cover is formed by a thermocompression embossing method. In the embodiment shown in FIG. 1, a side cover having a flower-like pattern is shown. The side cover may have various patterns by a thermocompression embossing method before being combined with the upper cover. An important point when the material of the side cover is subjected to thermocompression embossing is that individual patterns are superimposed on the rotation direction of an embossing roller (not shown). If you look at part B in Figure 1, you can see that the individual patterns are superimposed in the vertical direction. There are individual patterns that are not superimposed on the A part and the C part in FIG. 1, but this is because the upper or lower part having a pattern that overlaps with the pattern carved on this part is cut off. If the individual patterns are not superposed on each other in this way, an empty space is generated between the patterns before and after the embossing roller carved in the thermocompression embossing process. An empty space means that there is a space between a pattern that is engraved by a roller and a pattern that is engraved before (in time) and a pattern that is engraved after that. Due to such an empty space, a difference in height occurs between the part with the pattern to be engraved and the part without the pattern, so that the sharpness is high at the beginning of the individual pattern and the sharpness at the end. May fall, and deviations in sharpness may occur within a single individual pattern. The nonwoven fabric forming the side cover is basically a hydrophilic material, has a basis weight of about 10 gsm to 100 gsm, is composed of fine fibers having a thickness of 10 denier, and preferably 3 denier or less. As a result of repetitively carrying out an experiment in which various patterns are engraved on a nonwoven fabric using the thermocompression embossing method, a pattern consisting of only curves or a pattern that mixes straight lines and curves appropriately harmonizes with the absorbent product, resulting in an aesthetic effect. I discovered the fact that it evokes it. Also, in order to make it easy for users to recognize patterns, we discovered the fact that the thickness of straight lines and curved lines is more than 0.2mm and less than 3mm. The non-woven fabric that forms the side cover can be divided into a fuzzy surface and a smooth surface on the opposite side of the body, or it may or may not be divided. It is desirable to arrange the smooth surface so as to contact the wearer's body. This is because the embossed pattern has a sharpness that is superior to a fuzzy surface and is easily recognized by the user.
