Therefore, an object of the present invention is to provide a holder that is excellent in fit and resistant to dirt.
以下、本発明をその好ましい実施形態に基づき図面を参照しながら説明する。なお、以下の図面の記載において、同一又は類似の部分には、同一又は類似の符号を付している。図面は基本的に模式的なものであり、各寸法の比率などは現実のものとは異なる場合がある。
Hereinafter, the present invention will be described based on its preferred embodiments with reference to the drawings. In addition, in the following description of the drawings, the same or similar reference numerals are given to the same or similar parts. The drawings are basically schematic, and the ratio of each dimension may differ from the actual one.
図1~3には、本発明のホルダの一実施形態であるホルダ1が示されている。また図4及び図5には、本発明のホルダの使用例として、ホルダ1とこれに止着された吸収性パッド11とを含む、使い捨ておむつ10(以下、「おむつ10」ともいう。)が示されている。おむつ10は、本発明の吸収性物品、即ち本発明のホルダと該ホルダに装着可能な吸収性パッドとを備える吸収性物品の一実施形態である。おむつ10は、図4に示すように、ホルダ1と吸収性パッド11とがホルダ側止着構造6及びパッド側止着構造16を介して結合されたものであり、ホルダ1が有するウエスト開口部WHと、ホルダ1の高さ方向HDの下端部と吸収性パッド11の長手方向(後述する縦方向X)に沿う両側縁部とで画成される一対のレッグ開口部LH,LHとを有する。なお、吸収性パッド11は、ホルダ1の構成部材ではない。
1 to 3 show a holder 1, which is one embodiment of the holder of the present invention. 4 and 5 show a disposable diaper 10 (hereinafter also referred to as "diaper 10") including a holder 1 and an absorbent pad 11 secured thereto as an example of use of the holder of the present invention. It is shown. The diaper 10 is one embodiment of the absorbent article of the present invention, that is, an absorbent article comprising the holder of the present invention and an absorbent pad attachable to the holder. As shown in FIG. 4, the diaper 10 is constructed by connecting the holder 1 and the absorbent pad 11 via the holder-side fastening structure 6 and the pad-side fastening structure 16. WH and a pair of leg openings LH, LH defined by the lower end in the height direction HD of the holder 1 and both side edges along the longitudinal direction (longitudinal direction X described later) of the absorbent pad 11. . Note that the absorbent pad 11 is not a constituent member of the holder 1 .
セパレートタイプの吸収性物品であるおむつ10は、ホルダ1と吸収性パッド11とが止着構造6,16を介して結合・分離自在であるため、従来の非セパレートタイプの吸収性物品に比べて環境に対する負荷が低減されている。すなわち、着用者の腰周りに対応する部分(ホルダ相当部分)と着用者の股間部に対応する部分(吸収性パッド相当部分)とが一体不可分である従来の非セパレートタイプの吸収性物品を使用後に廃棄する場合、ホルダ相当部分は汚れていなくても、排泄物で汚れた状態の吸収性パッド相当部分とともに廃棄せざるを得なかったが、おむつ10であれば、ホルダ1はそのままで吸収性パッド11のみを新品と交換すればよいため、非セパレートタイプの吸収性物品に比べてゴミ廃棄量、二酸化炭素排出量が低減され、環境に対する負荷の低減に貢献することができる。
また、おむつ10の着用中、吸収性パッド11はホルダ1に着脱可能に固定されているので、該吸収性パッド11を新品に交換する作業は簡単であり、おむつ10は、従来の非セパレートタイプの吸収性物品に比べて交換作業の負荷が大幅に軽減されている。 In thediaper 10, which is a separate type absorbent article, the holder 1 and the absorbent pad 11 can be freely connected and separated via the fixing structures 6, 16, so compared to conventional non-separate type absorbent articles, The load on the environment is reduced. That is, a conventional non-separate type absorbent article is used in which the portion corresponding to the waist of the wearer (portion corresponding to the holder) and the portion corresponding to the crotch portion of the wearer (portion corresponding to the absorbent pad) are inseparably integrated. When discarding later, even if the portion corresponding to the holder is not soiled, it has to be discarded together with the portion corresponding to the absorbent pad that is soiled with excrement. Since only the pad 11 needs to be replaced with a new one, the amount of garbage disposal and carbon dioxide emissions are reduced compared to non-separate type absorbent articles, and the burden on the environment can be reduced.
In addition, since theabsorbent pad 11 is detachably fixed to the holder 1 while the diaper 10 is being worn, the work of replacing the absorbent pad 11 with a new one is simple, and the diaper 10 is similar to the conventional non-separate type. The burden of replacement work is greatly reduced compared to other absorbent articles.
また、おむつ10の着用中、吸収性パッド11はホルダ1に着脱可能に固定されているので、該吸収性パッド11を新品に交換する作業は簡単であり、おむつ10は、従来の非セパレートタイプの吸収性物品に比べて交換作業の負荷が大幅に軽減されている。 In the
In addition, since the
ホルダ1は、着用者の腰周りに環状に装着されるとともに、吸収性パッド11を着用者に装着した状態、すなわち着用状態に保持可能なものであり、着用者の身長方向に沿う高さ方向HD及び胴周り方向に沿う周方向CDを有している。ホルダ1には、吸収性パッド11が有するパッド側止着構造16を脱着可能に止着可能なホルダ側止着構造6が設けられている。

When the extension length H1 from the body portion 2 is constant, it is preferable that the lower end portion 25b of the extension portion 21 is linear parallel to the circumferential direction CD as in the present embodiment. 2, the lower end portion 25b of the extending portion 21 has fine unevenness when viewed microscopically, but may be linear extending in the circumferential direction CD when viewed macroscopically. For example, when the lower end portion 25b has fine irregularities and the distance in the height direction HD between the apex of the convex portion and the bottom point of the concave portion is 10 mm or less, preferably 5 mm or less, the lower end portion 25b is a flat edge. 25b.
本実施形態では、ホルダ1の高さ方向HDの下端縁1bは、欠落部23の頂部23a、一対の傾斜縁部23b,23b、及び一対のフラット縁部25b,25bにより構成されている。延出部21は、欠落部23の両側それぞれに、傾斜縁部23b、フラット縁部25b及び接合部Sによって囲まれた部分である延出部本体25を有する。
In this embodiment, the lower edge 1b of the holder 1 in the height direction HD is composed of the top 23a of the missing portion 23, a pair of inclined edges 23b, 23b, and a pair of flat edges 25b, 25b. The extending portion 21 has an extending portion main body 25 which is a portion surrounded by the inclined edge portion 23b, the flat edge portion 25b and the joint portion S on both sides of the missing portion 23 respectively.
ホルダ1は、中央領域Cから側部領域Eにわたる欠落部23を有するので、ホルダ1の装着状態において、ホルダ1の下端縁1bが着用者の排泄部から離れた位置に配されることになる。そのため、該下端縁1bが着用者の排泄物に触れにくくなり、ホルダ1が汚れることを防ぐことができる。
しかも、欠落部23が傾斜縁部23bを有するので、欠落部23の両側に位置する部分の下端縁1b近傍が、着用者の肌にしっかりフィットするようになり、非肌対向面側又は肌対向面側にめくれてしまうことを防ぐことができる。したがって、ホルダ1は、フィット性にも優れる。
このように、本実施形態のホルダ1は、フィット性に優れるとともに、汚れにくくなっている。
これに対し、特許文献1~3のホルダが有する切り欠きやスリット等は、切り欠きやスリットの両側に、めくれやすい角部を有しており、違和感が発生しやすい。特許文献2及び3が有する切り欠き及びスリットは、周方向の幅が短く、ホルダが汚れやすい。 Since theholder 1 has the missing portion 23 extending from the central region C to the side region E, the lower edge 1b of the holder 1 is arranged away from the wearer's excretory part when the holder 1 is worn. . Therefore, the lower edge 1b is less likely to come into contact with the wearer's excrement, and the holder 1 can be prevented from being soiled.
Moreover, since thecutout portion 23 has the inclined edge portion 23b, the vicinity of the lower edge 1b of the portions located on both sides of the cutout portion 23 can be firmly fitted to the wearer's skin. It is possible to prevent the surface from being turned over. Therefore, the holder 1 is also excellent in fit.
As described above, theholder 1 of the present embodiment has excellent fitting properties and is resistant to dirt.
On the other hand, the cutouts, slits, and the like of the holders ofPatent Documents 1 to 3 have corners on both sides of the cutouts or slits that are easily turned up, which tends to cause discomfort. The cutouts and slits in Patent Documents 2 and 3 are short in width in the circumferential direction, and the holder easily becomes dirty.

本発明のホルダにおいては、欠落部23を有する延出部21を、腹側部F及び背側部Rのいずれか一方のみに有していてもよいが、本実施形態のホルダ1のように、該延出部21を、腹側部F及び背側部Rの両方に有していることが好ましい。こうすることにより、腹側部F及び背側部Rそれぞれの下端縁1bを、着用者のペニス、肛門等の排泄部から離れた位置に配することができるので、ホルダ1が汚れることを一層効果的に防ぐことができる。
In the holder of the present invention, only one of the ventral portion F and the dorsal portion R may have the extending portion 21 having the missing portion 23, but like the holder 1 of the present embodiment, It is preferable to have the extending portion 21 on both the ventral portion F and the dorsal portion R. By doing so, the lower edges 1b of the ventral portion F and the dorsal portion R can be placed away from the wearer's excretory parts such as the penis and anus, thereby further preventing the holder 1 from getting dirty. can be effectively prevented.
延出部21は、欠落部23の両側それぞれに、腹側部F又は背側部Rの幅方向CDに伸縮する伸縮部を有していることが好ましい。こうすることにより、ホルダ1を装着したときに、延出部21、特に延出部本体25が着用者の胴周りにフィットするようになるので、ホルダ1のフィット性を一層向上させることができる。伸縮部は、例えば、延出部21に、幅方向CDに伸縮可能な弾性部材を配置することによって形成することができる。また、延出部21の全部又は一部を、幅方向CDに伸縮性を有する伸縮シートにより構成することによって形成することもできる。

By doing so, when the holder 1 is worn, the extension 21, particularly the extension main body 25, fits around the waist of the wearer, so that the fit of the holder 1 can be further improved. . The stretchable portion can be formed, for example, by arranging an elastic member stretchable in the width direction CD on the extension portion 21 . Alternatively, all or part of the extending portion 21 may be formed by an elastic sheet having elasticity in the width direction CD.
本実施形態のホルダ1は、上述のように、周方向CDに伸縮可能に配置された弾性部材5を備えており、本体部2は、周方向CDの伸縮性を有している。本体部2と延出部21とは、伸縮応力が同じであってもよいし、異なっていてもよい。本体部2の伸縮応力と延出部21の伸縮応力とが異なる場合、本体部2における延出部21に隣接する領域の伸縮応力S1より、延出部21の伸縮部の伸縮応力S2の方が小さいことが好ましい。仮に、本体部2における延出部21に隣接する領域の伸縮応力S1と、延出部21の伸縮部の伸縮応力S2とを上述のような関係とすることによって、ホルダ1のフィット性を向上させるとともに、延出部21がめくれることを防ぐことができる。この効果が一層顕著に奏されるようにする観点から、前記伸縮応力S1に対する前記伸縮応力S2の比S2/S1は、好ましくは0.05以上、より好ましくは0.10以上、更に好ましくは0.20以上であり、また好ましくは0.95以下、より好ましくは0.90以下、更に好ましくは0.80以下であり、また好ましくは0.05以上0.95以下、より好ましくは0.10以上0.90以下、更に好ましくは0.20以上0.80以下である。伸縮応力は、以下の方法により測定することができる。

The main body portion 2 and the extending portion 21 may have the same or different stretching stresses. When the expansion/contraction stress of the body portion 2 and the expansion/contraction stress of the extension portion 21 are different, the expansion/contraction stress S2 of the expansion/contraction portion of the extension portion 21 is greater than the expansion/contraction stress S1 of the region adjacent to the extension portion 21 in the body portion 2. is preferably small. If the stretching stress S1 of the region adjacent to the extending portion 21 in the main body portion 2 and the stretching stress S2 of the stretching portion of the extending portion 21 are in the relationship described above, the fit of the holder 1 is improved. In addition, it is possible to prevent the extension part 21 from being turned over. From the viewpoint of achieving this effect more remarkably, the ratio S2/S1 of the stretching stress S2 to the stretching stress S1 is preferably 0.05 or more, more preferably 0.10 or more, and still more preferably 0. 0.20 or more, preferably 0.95 or less, more preferably 0.90 or less, still more preferably 0.80 or less, more preferably 0.05 or more and 0.95 or less, more preferably 0.10 0.90 or less, more preferably 0.20 or more and 0.80 or less.

The upper limit of the angle α can be set to 175°, for example.
本実施形態では、ホルダ1の下端縁1bは直線のみで構成されているが、ホルダ1の下端縁1bは、図6に示すように、直線及び曲線により構成されていてもよい。図6に示す変形例では、欠落部23の頂部23a及びフラット縁部25bが直線及び曲線により構成されており、傾斜縁部23bは曲線により構成されている。図6に示す変形例のように、傾斜縁部23b及びフラット縁部25bの交点付近、又は、傾斜縁部23b及び欠落部23の頂部23aの交点付近を多項近似式により曲線に近似できる場合、傾斜縁部23bとフラット縁部25bとのなす角αは、以下のようにして測定することができる。
In this embodiment, the lower edge 1b of the holder 1 is composed only of straight lines, but the lower edge 1b of the holder 1 may be composed of straight lines and curved lines as shown in FIG. In the modification shown in FIG. 6, the top portion 23a and the flat edge portion 25b of the missing portion 23 are composed of straight lines and curved lines, and the inclined edge portion 23b is composed of curved lines. As in the modification shown in FIG. 6, when the vicinity of the intersection of the inclined edge portion 23b and the flat edge portion 25b or the vicinity of the intersection of the inclined edge portion 23b and the top portion 23a of the missing portion 23 can be approximated to a curve by a polynomial approximation, The angle α between the inclined edge portion 23b and the flat edge portion 25b can be measured as follows.
まず、傾斜縁部23b及びフラット縁部25bの交点付近を多項近似式により曲線に近似して、該曲線と同一の曲率を有し、傾斜縁部23b及びフラット縁部25bに接する仮想円R1を考える。次に、傾斜縁部23b及び欠落部23の頂部23aの交点付近を多項近似式により曲線に近似して、該曲線と同一の曲率を有し、傾斜縁部23b及び欠落部23の頂部23aに接する仮想円R2を考える。そして、仮想円R1及び仮想円R2の両方に接する仮想接線Q1を引く。仮想接線Q1とフラット縁部25bとのなす角を、傾斜縁部23bとフラット縁部25bとのなす角αとすることができる。
First, the vicinity of the intersection of the inclined edge portion 23b and the flat edge portion 25b is approximated to a curve by a polynomial approximation, and a virtual circle R1 having the same curvature as the curve and being in contact with the inclined edge portion 23b and the flat edge portion 25b is formed. think. Next, the vicinity of the intersection of the slanted edge portion 23b and the apex portion 23a of the missing portion 23 is approximated to a curve by a polynomial approximation formula, and has the same curvature as the curve. Consider a tangent virtual circle R2. An imaginary tangent line Q1 that touches both the imaginary circle R1 and the imaginary circle R2 is then drawn. The angle between the virtual tangent line Q1 and the flat edge 25b can be defined as the angle α between the inclined edge 23b and the flat edge 25b.
またホルダ1の下端縁1bは、図7に示すように、凹凸が繰り返された形状であってもよい。図7に示す変形例では、ホルダ1の下端縁1bは、ギザギザ状となっている。図7に示す変形例のように、傾斜縁部23b及び延出部21の下端部25bの交点付近、又は、傾斜縁部23b及び欠落部23の頂部23aの交点付近を多項近似式により曲線に近似することが困難である場合、以下のようにして、傾斜縁部23bとフラット縁部25bとのなす角αを測定することができる。
Also, the lower edge 1b of the holder 1 may have a shape in which unevenness is repeated, as shown in FIG. In the modification shown in FIG. 7, the lower edge 1b of the holder 1 is jagged. As in the modification shown in FIG. 7, the vicinity of the intersection of the inclined edge portion 23b and the lower end portion 25b of the extension portion 21 or the vicinity of the intersection point of the inclined edge portion 23b and the top portion 23a of the missing portion 23 is curved by a polynomial approximation. If approximation is difficult, the angle α between the slanted edge 23b and the flat edge 25b can be measured as follows.

An imaginary tangent line Q2 that touches both the imaginary circle R3 and the imaginary circle R4 is then drawn. The angle formed between the virtual tangent line Q2 and the lower end portion 25b of the extending portion 21 can be the angle α formed between the inclined edge portion 23b and the flat edge portion 25b. When the lower end portion 25b of the extending portion 21 is not a straight line parallel to the circumferential direction CD, the flat edge portion 25b is approximated to a straight line T parallel to the circumferential direction CD by the method of least squares, and the approximate straight line T and the virtual tangent line Q2 are approximated. can be defined as the angle α between the inclined edge portion 23b and the flat edge portion 25b.
また、図1に示す実施形態では、傾斜縁部23bは、本体部2からの延出長さが連続的に変化していたが、傾斜縁部23bは、図8及び図9に示すように、本体部2からの延出長さが段階的に変化していてもよい。図8に示すように、傾斜縁部23bの両端を通る仮想線Q3とフラット縁部25bとのなす角を、傾斜縁部23bとフラット縁部25bとのなす角αとすることもできる。
In addition, in the embodiment shown in FIG. 1, the inclined edge portion 23b extends continuously from the main body portion 2, but the inclined edge portion 23b is changed as shown in FIGS. , the extension length from the body portion 2 may be changed stepwise. As shown in FIG. 8, the angle between the flat edge portion 25b and the imaginary line Q3 passing through both ends of the inclined edge portion 23b may be the angle α between the inclined edge portion 23b and the flat edge portion 25b.
