Description

本発明は、連結式おむつ、すなわち、接着剤層を有する止着テープ、メカニカルファスニングテープ又はメカニカルファスナー、または留め金などの止着手段を利用し、この止着手段を腹側と連結する連結手段を有する使い捨ておむつに関する。   The present invention utilizes a connecting diaper, that is, a connecting means for connecting a fastening means such as a fastening tape having an adhesive layer, a mechanical fastening tape or a mechanical fastener, or a clasp, to the abdomen. It relates to the disposable diaper which has.

いわゆるテープ式(使い捨て)おむつは、パンツ型のおむつが幼児を対象とするものであるのに対し、乳児用を中心に採用されている。テープ式おむつとしては、近年では、粘着テープ式のものに代わって、メカニカルファスニングテープが汎用されている。また、留め金(ホック)式のおむつも知られているが、おむつカバーを中心として採用されているのみで、市販品のおむつ自体としては採用されていない。
いずれにしても、おむつ一般として体液の漏れの多くは脚周りにおいて生じる。その原因のほとんどが、着用時において、吸収体と肌との離間を生じることが原因である。そこで、バリヤーカフスによって、肌との接触を保持し、横漏れを防止する手法が多く採用されているが、吸収体と肌との離間距離が大きい場合には、バリヤーカフスの遠位縁の肌との接触が保てず、漏れの生じる原因となる。
このために、装着者(母親など)は、おむつを装着後に、おむつを吊り上げる(持ち上げる)ようにし、吸収体と肌とが密着するようにしている。
しかし、おむつが股下側にずれ落ちた場合、吸収体と肌との密着性は失われ、その密着性を保持する機能はない。
特許文献1には、パンツ型おむつにおいて、第1連結帯及び第2連結帯によって液吸収性パッドを吊り上げるようにしたものが開示されている。
しかし、このものは本発明の連結式おむつとは異なり、あくまでも予め脇部がウエスト回りに連結されているパンツ型おむつであり、第1連結帯及び第2連結帯は前後方向及び横方向に伸縮性を有するとしても、ウエスト回り方向(横方向)に伸縮する機能は有しない。
特許第3811086号
So-called tape-type (disposable) diapers are mainly used for infants, whereas pants-type diapers are intended for infants. As a tape-type diaper, in recent years, a mechanical fastening tape is widely used instead of an adhesive tape-type diaper. Moreover, although a clasp (hook) type diaper is also known, it is employed mainly for a diaper cover, and is not employed as a commercially available diaper itself.
In any case, as a general rule, most body fluid leaks occur around the legs. Most of the causes are caused by separation between the absorbent body and the skin at the time of wearing. Therefore, many methods have been adopted to maintain contact with the skin and prevent side leakage with barrier cuffs, but when the distance between the absorber and the skin is large, the skin at the distal edge of the barrier cuffs is used. The contact with can not be maintained, causing leakage.
For this reason, a wearer (such as a mother) lifts (lifts) the diaper after the diaper is worn, so that the absorbent body and the skin are in close contact with each other.
However, when the diaper slips down to the crotch side, the adhesion between the absorbent body and the skin is lost, and there is no function to maintain the adhesion.
Patent Document 1 discloses a pant-type diaper in which a liquid absorbent pad is lifted by a first connection band and a second connection band.
However, unlike the connected diaper of the present invention, this is a pants-type diaper whose side portions are connected in advance around the waist, and the first and second connection bands expand and contract in the front-rear direction and the lateral direction. Even if it has the property, it does not have a function of expanding and contracting in the direction around the waist (lateral direction).
Japanese Patent No. 3811086

したがって、本発明の主たる課題は、連結式おむつにおいて、ウエスト部の弾性伸縮部材によりウエストを密着させるとともに、ウエスト部の弾性伸縮部材の伸長に伴って吸収性本体が肌と密着または接近するようになり、しかもおむつが股下側にずれ落ちたとしても吸収性本体を依然として肌と密着または接近する状態に維持することが可能なおむつを提供することにある。   Accordingly, the main problem of the present invention is that, in a connected diaper, the waist is brought into close contact with the elastic elastic member of the waist portion, and the absorbent main body is in close contact with or close to the skin as the elastic elastic member of the waist portion is extended. In addition, an object of the present invention is to provide a diaper capable of maintaining the absorbent main body in close contact with or close to the skin even if the diaper slips down to the crotch side.

上記課題を解決した本発明は次掲のとおりである。

The present invention that has solved the above problems is as follows.
<Invention of Claim 1>
A liquid-permeable top sheet, a liquid-impermeable back sheet, and an absorbent body interposed therebetween, an absorptive main body consisting of an abdominal part, a crotch part, and a dorsal part;
An elastic elastic member that is fixed at each end of the abdominal side and the back side of the absorbent main body, is in a strip shape longer than the absorbent main body in the horizontal direction, and contracts in the vertical direction when extended in the horizontal direction;
Fastening means fixed to the left and right ends of the elastic elastic member on either the ventral side or the back side;
A connecting means disposed on the other side and connectable to the fastening means;
An articulated diaper characterized by including.

(作用効果)
図1及び図2の符号をもって説明すると、吸収性本体10の腹側及び背側のそれぞれの端部において固定され、横方向に吸収性本体よりも長い帯状で、横方向に伸ばすと縦方向に収縮する弾性伸縮部材20、20が固定される。腹側または背側どちらか一方側、図1の例では背側の弾性伸縮部材20の左右両端部に止着手段2が固定されている。これに対し、他方側に止着手段2と連結できる連結手段が形成または設けられる。たとえば止着手段が接着剤層を有する止着テープであれば、その止着テープが接着される他方側の弾性伸縮部材20の外面自体、またはその外面に設けられた別のシートの外面が連結手段を構成する。また、止着手段がメカニカルファスニングテープであれば、そのメカニカルファスニングテープと対をなすメカニカルファスニング要素が、他方側の弾性伸縮部材20の外面、またはその外面に設けられた別のシートの外面に設けられ、これが連結手段を構成する。
かくして、止着手段と連結手段とを連結するに際し、図2に示すように、弾性伸縮部材20を横方向(図2の左右方向)に伸長させる(伸長方向を符号F0で示す。)と、弾性伸縮部材20が縦方向(図2の上下方向)に収縮する(収縮方向を符号Fで示す。)。その結果、弾性伸縮部材20の幅方向の収縮が、図3の矢印Fのように、吸収性本体10の股下部を前後方向に持ち上げる(吊り上げる)ように作用する。また、着用者が座ると胴回りが膨らむことにより、弾性伸縮部材の伸長に伴って、おむつが縦方向に伸張されるため、吸収性本体が股部に引き寄せられ、隙間ができにくいものとなる。
かくして、吸収性本体10が着用者の肌側に接近または密着するようになり、股下部における横漏れを防止する。また、弾性伸縮部材20の伸長に伴う復元力が、ウエスト回りを締め付け、前後漏れ防止効果が高いものとなる。
仮に、着用後に着用者の動きなどによって、おむつがずれ落ちたとしても、胴回りの周長は腰部から臀部に下がるに従って大きくなるため、弾性伸縮部材20は横方向にさらに伸長され、吸収性本体10の股下部を前後方向にさらに持ち上げる(吊り上げる)ように力が作用するので、吸収性本体10が着用者の肌側に接近または密着する状態を維持できる。
また、上記形態では、弾性伸縮部材20を前後に設けたので、前後方向一方に設ける場合に比較して、吸収性本体10の股下部を前後方向に持ち上げる量が多くなり、吸収性本体10が着用者の肌側に好適に接近または密着するようになる。
従来、通常のおむつは着用者が座ると足回りに隙間ができやすいが、本発明の構造によれば、着用者が座ると胴回りが膨らむことにより、弾性伸縮部材の伸長に伴って、吸収性本体が股部に引き寄せられ、隙間ができにくい。また、個人差で股間がゆるくなるようにあてた場合でも、止着手段、たとえばテープを引っ張って止着する際に、吸収性本体が股間に引き寄せられるため、股間の緩みで漏れが生じることが少ない。
(Function and effect)
1 and 2, the absorbent body 10 is fixed at the respective ventral and dorsal end portions of the absorbent main body 10 and has a strip shape longer than the absorbent main body in the lateral direction. The elastic elastic members 20 and 20 that contract are fixed. The fastening means 2 is fixed to either the left or right end of the elastic elastic member 20 on the back side, in the example of FIG. On the other hand, a connecting means that can be connected to the fastening means 2 is formed or provided on the other side. For example, when the fastening means is a fastening tape having an adhesive layer, the outer surface of the elastic elastic member 20 on the other side to which the fastening tape is bonded, or the outer surface of another sheet provided on the outer surface is connected. Configure the means. If the fastening means is a mechanical fastening tape, the mechanical fastening element that forms a pair with the mechanical fastening tape is provided on the outer surface of the elastic elastic member 20 on the other side or on the outer surface of another sheet provided on the outer surface. This constitutes the connecting means.
Thus, when the fastening means and the connecting means are connected, as shown in FIG. 2, the elastic elastic member 20 is extended in the lateral direction (left-right direction in FIG. 2) (the extension direction is indicated by the symbol F0). The elastic elastic member 20 contracts in the vertical direction (vertical direction in FIG. 2) (the contraction direction is indicated by a symbol F). As a result, the contraction in the width direction of the elastic elastic member 20 acts to lift (lift) the crotch part of the absorbent main body 10 in the front-rear direction as indicated by the arrow F in FIG. Further, when the wearer sits down, the waistline swells, so that the diaper is stretched in the vertical direction as the elastic elastic member is stretched, so that the absorbent main body is attracted to the crotch portion, and a gap is hardly formed.
Thus, the absorbent main body 10 comes close to or closely contacts the wearer's skin side, thereby preventing side leakage at the crotch. Moreover, the restoring force accompanying the expansion | extension of the elastic expansion-contraction member 20 tightens a waist periphery, and becomes a thing with a high front-and-back leak prevention effect.
Even if the diaper slips down due to the movement of the wearer after wearing, the circumference of the waistline increases as it falls from the waist to the buttocks, so the elastic elastic member 20 is further extended in the lateral direction and the absorbent main body 10 Since the force acts so as to further lift (hang) the crotch part in the front-rear direction, it is possible to maintain the state in which the absorbent main body 10 approaches or closely contacts the wearer's skin side.
Moreover, in the said form, since the elastic elastic member 20 was provided in the front-back direction, compared with the case where it provides in the front-back direction one side, the amount which lifts the crotch part of the absorptive main body 10 to the front-back direction increases, and the absorptive main body 10 is It comes to approach or closely adhere to a wearer's skin side suitably.
Conventionally, when a wearer sits, a normal diaper tends to have a gap around the undercarriage, but according to the structure of the present invention, the waistline swells when the wearer sits, so that the elastic stretch member expands. The body is drawn to the crotch, making it difficult to create a gap. Even when the crotch is loosened due to individual differences, when the fastening means, for example, by pulling the tape, the absorbent main body is attracted between the crotch, so that leakage may occur due to the loosening of the crotch. Few.

A connected diaper characterized by that.

(作用効果)
上記各例では、弾性伸縮部材に対して止着手段を設けたものであるが、製品外面の肌触りを向上させる、見栄えをよくするなどの目的で、吸収性本体に対して外装シートを設ける態様においても、上記の機能を発揮させる構造が提供される。
すなわち、図5に示すように、吸収性本体10の裏面側に外装シート1が設けられ、この外装シート1に各弾性伸縮部材20、20が固定される。そして、外装シート1の腹側または背側どちらか一方側(図示例では背側)において、外装シート1の両側部に止着手段2、2が固定され、並びに他方側(図示例では腹側)の端部に配置され、止着手段2と連結できる連結手段とを備える。
そして、止着手段2及び連結手段は、対応する弾性伸縮部材20の横方向延長が重なる縦方向位置又はその縦方向近傍位置にあり、弾性伸縮部材20を、止着手段2、2相互を横方向に離間させたとき、横方向に伸ばされる状態で外装シート1に対して固定されている。
かくして、止着手段2、2と連結手段とを連結するに際し、図7に示すように、弾性伸縮部材20を横方向(図7の紙面を貫く方向)に伸長させると、弾性伸縮部材20が縦方向(図7の左右方向)に収縮する(収縮方向を符号Fで示す。)。その結果、弾性伸縮部材20の幅方向の収縮が、図7及び図8の矢印Fのように、吸収性本体10の股下部を前後方向に持ち上げる(吊り上げる)ように作用する。
かくして、吸収性本体10が着用者の肌側に接近または密着するようになり、股下部における横漏れを防止する。また、弾性伸縮部材20の伸長に伴う復元力が、ウエスト回りを締め付け、前後漏れ防止効果が高いものとなる。
仮に、着用後に着用者の動きなどによって、おむつがずれ落ちたとしても、胴回りの周長は腰部から臀部に下がるに従って大きくなるため、弾性伸縮部材20は横方向にさらに伸長され、吸収性本体10の股下部を前後方向にさらに持ち上げる(吊り上げる)ように力が作用するので、吸収性本体10が着用者の肌側に接近または密着する状態を維持できる。
また、上記形態では、弾性伸縮部材20を前後に設けたので、前後方向一方に設ける場合に比較して、吸収性本体10の股下部を前後方向に持ち上げる量が多くなり、吸収性本体10が着用者の肌側に好適に接近または密着するようになる。

また、「弾性伸縮部材は、前記止着手段相互を横方向に離間させたとき、横方向に伸ばされる状態で前記外装シートに対して固定されている」形態の第1の例は、弾性伸縮部材20がその伸長状態で外装シート1に固定される形態を挙げることができる。この形態では、製品状態では弾性伸縮部材20及び外装シート1が横方向に収縮した状態にあり、止着手段2、2相互を横方向に離間させたとき弾性伸縮部材20及び外装シート1が収縮した状態から伸長した状態になる。第2の例としては、外装シート1を伸縮性の材料で構成するか、二枚の外装シート2、2間に糸ゴムや弾性伸縮部材を設け、その外装シート部材と弾性伸縮部材20とを接合するなどの形態を採ることができるものである。
(Function and effect)
In each of the above examples, the fastening means is provided for the elastic elastic member, but the exterior sheet is provided on the absorbent main body for the purpose of improving the touch of the outer surface of the product and improving the appearance. The structure for exhibiting the above functions is also provided.
That is, as shown in FIG. 5, the exterior sheet 1 is provided on the back side of the absorbent main body 10, and the elastic elastic members 20, 20 are fixed to the exterior sheet 1. The fastening means 2 and 2 are fixed to both sides of the exterior sheet 1 on either the stomach side or the back side of the exterior sheet 1 (the back side in the illustrated example), and the other side (the stomach side in the illustrated example). And a connecting means that can be connected to the fastening means 2.
Then, the fastening means 2 and the connecting means are in the longitudinal position where the lateral extensions of the corresponding elastic stretchable members 20 overlap or in the vicinity of the longitudinal direction. When spaced apart in the direction, it is fixed to the exterior sheet 1 in a state of being stretched in the lateral direction.
Thus, when connecting the fastening means 2, 2 and the connecting means, as shown in FIG. 7, when the elastic elastic member 20 is extended in the lateral direction (direction passing through the paper surface of FIG. 7), the elastic elastic member 20 is It contracts in the vertical direction (left-right direction in FIG. 7) (the contraction direction is indicated by symbol F). As a result, the contraction in the width direction of the elastic elastic member 20 acts to lift (lift) the crotch part of the absorbent main body 10 in the front-rear direction, as indicated by an arrow F in FIGS.
Thus, the absorbent main body 10 comes close to or closely contacts the wearer's skin side, thereby preventing side leakage at the crotch. Moreover, the restoring force accompanying the expansion | extension of the elastic expansion-contraction member 20 tightens a waist periphery, and becomes a thing with a high front-and-back leak prevention effect.
Even if the diaper slips down due to the movement of the wearer after wearing, the circumference of the waistline increases as it falls from the waist to the buttocks, so the elastic elastic member 20 is further extended in the lateral direction and the absorbent main body 10 Since the force acts so as to further lift (hang) the crotch part in the front-rear direction, it is possible to maintain the state in which the absorbent main body 10 approaches or closely contacts the wearer's skin side.
Moreover, in the said form, since the elastic elastic member 20 was provided in the front-back direction, compared with the case where it provides in the front-back direction one side, the amount which lifts the crotch part of the absorptive main body 10 to the front-back direction increases, and the absorptive main body 10 is It comes to approach or closely adhere to a wearer's skin side suitably.
In this case, as shown in FIG. 8, the absorbent main body 10 and the exterior sheet 1 can be appropriately joined such as not being joined together, but partially joined or joined together. is there.
Further, the first example of the form “the elastic elastic member is fixed to the exterior sheet in a state of being extended in the lateral direction when the fastening means are separated from each other in the lateral direction” is an elastic expansion and contraction. The form which the member 20 is fixed to the exterior sheet | seat 1 in the expansion | extension state can be mentioned. In this form, in the product state, the elastic elastic member 20 and the exterior sheet 1 are contracted in the lateral direction, and when the fastening means 2 and 2 are separated from each other in the lateral direction, the elastic elastic member 20 and the exterior sheet 1 contract. It becomes the extended state from the state. As a second example, the exterior sheet 1 is made of a stretchable material, or a rubber thread or an elastic stretch member is provided between the two exterior sheets 2 and 2, and the exterior sheet member and the elastic stretch member 20 are It can take the form of joining.

As in the fourth and fifth aspects, even when the elastic elastic member is provided only on one of the back side and the abdomen side, the same function as described above is exhibited.

本発明においては、要すれば、連結式おむつにおいて、止着手段相互を離間させるように弾性伸縮部材を伸長させる、あるいは連結後において、着用者が座ると胴回りが膨らむことによる弾性伸縮部材の伸長に伴って、吸収性本体が股部に引き寄せられ、隙間ができにくいものとなる。そして、弾性伸縮部材の復元力によって、ウエスト回り方向に締め付けて密着させるとともに、装着時に吸収性本体の股下部が肌と密着または接近するようになり、しかもおむつが股下側にずれ落ちたとしても吸収性本体を依然として肌と密着または接近する状態に維持することが可能となる。したがって、ウエスト部分及び股下部からの漏れを防止することができる。   In the present invention, if necessary, in the connected diaper, the elastic elastic member is extended so that the fastening means are separated from each other, or after the connection, the elastic elastic member is expanded by the waistline expanding when the wearer sits down. As a result, the absorbent main body is attracted to the crotch, making it difficult to form a gap. And even if the elastic crotch member is tightened in close contact with the waist, and the crotch part of the absorbent main body comes into close contact with or approaches the skin when worn, and the diaper slips down to the crotch side It is possible to keep the absorbent main body still in close contact with or close to the skin. Therefore, leakage from the waist part and the crotch part can be prevented.

以下本発明をいくつかの実施の形態を挙げて本発明をさらに詳説する。
<第1の実施の形態>
図1〜図5は第1の実施の形態を示したものである。図1において、Xが横方向、Yが前後方向をそれぞれ示し、前後方向Yの中間は股下部Lとなっている。股下部Lは脚周りに該当する前後方向のおむつの中間領域である。
10は吸収性本体で、表面側から体液を受け入れて保持し裏面側への漏れを防止するものである。
吸収性本体10の形態は適宜でよいが、たとえば不織布からなかるトップシート11と、液不透過性のたとえばポリエチレンなどのプラスチックバックシート12と、それらの間に介在された吸収体13とを形態を挙げることができる。吸収体13としては綿状パルプと高吸収性ポリマーとを含むもののほか、綿状パルプ等の短繊維を積繊したものに換えて、フィラメントの集合体からなるもの等も使用できる。フィラメントの集合体は、トウ(繊維束)を開繊することにより得ることができる。トウ構成繊維としては、例えば、多糖類又はその誘導体(セルロース、セルロースエステル、キチン、キトサンなど)、合成高分子(ポリエチレン、ポリプロピレン、ポリアミド、ポリエステル、ポリラクタアミド、ポリビニルアセテートなど)などを用いることができるが、特に、セルロースエステルおよびセルロースが好ましい。
吸収性本体10には、必要により、バリヤーカフス14を設けることができる。図示例のバリヤーカフス14は、自由部先端に糸ゴム14Aを設け、使用状態において、自由部を起立させるようにしたものである。
吸収性本体10の腹側及び背側のそれぞれの端部において、横方向(図1におけるX方向)に吸収性本体10よりも長い帯状で、横方向に伸ばすと縦方向に収縮する弾性伸縮部材20、20が固定される。腹側または背側どちらか一方側、図1の例では背側の弾性伸縮部材20の左右両端部に止着手段2が固定されている。止着手段としては、粘着(接着)テープやメカニカルファスニングテープを挙げることができる。
これに対し、他方側に止着手段2と連結できる連結手段が形成または設けられる。たとえば止着手段が接着剤層を有する止着テープであれば、その止着テープが接着される弾性伸縮部材20の外面自体、またはその外面に設けられた別のシートの外面が連結手段を構成する。また、止着手段が図示のようにメカニカルファスニングテープ2であれば、そのメカニカルファスニングテープと対をなすメカニカルファスニング要素が、弾性伸縮部材20の外面、またはその外面に設けられた別のシート21(図3及び図4参照)の外面に設けられ、これが連結手段を構成する。
Hereinafter, the present invention will be described in more detail with reference to some embodiments.
<First Embodiment>
1 to 5 show a first embodiment. In FIG. 1, X indicates a lateral direction, Y indicates a front-rear direction, and the middle of the front-rear direction Y is a crotch L. The crotch L is an intermediate region of the diaper in the front-rear direction corresponding to the periphery of the leg.
10 is an absorptive main body, which receives and holds body fluids from the front side and prevents leakage to the back side.
Although the form of the absorptive main body 10 may be appropriate, for example, a top sheet 11 made of a nonwoven fabric, a liquid-impermeable plastic back sheet 12 such as polyethylene, and an absorbent body 13 interposed therebetween are formed. Can be mentioned. As the absorbent 13, in addition to those containing cotton-like pulp and a superabsorbent polymer, those made of aggregates of filaments can be used in place of those containing short fibers such as cotton-like pulp. An aggregate of filaments can be obtained by opening a tow (fiber bundle). Examples of tow fibers include polysaccharides or derivatives thereof (cellulose, cellulose ester, chitin, chitosan, etc.), synthetic polymers (polyethylene, polypropylene, polyamide, polyester, polylactamamide, polyvinyl acetate, etc.). In particular, cellulose esters and cellulose are preferable.
The absorbent main body 10 may be provided with a barrier cuff 14 if necessary. The barrier cuff 14 of the illustrated example is provided with a rubber thread 14A at the tip of a free part so that the free part stands up in use.
An elastic elastic member that has a strip shape that is longer than the absorbent main body 10 in the lateral direction (X direction in FIG. 1) at each end on the ventral side and the back side of the absorbent main body 10 and contracts in the vertical direction when stretched in the lateral direction. 20 and 20 are fixed. The fastening means 2 is fixed to either the left or right end of the elastic elastic member 20 on the back side, in the example of FIG. Examples of the fastening means include an adhesive (adhesive) tape and a mechanical fastening tape.
On the other hand, a connecting means that can be connected to the fastening means 2 is formed or provided on the other side. For example, if the fastening means is a fastening tape having an adhesive layer, the outer surface of the elastic elastic member 20 to which the fastening tape is bonded or the outer surface of another sheet provided on the outer surface constitutes the connecting means. To do. Further, if the fastening means is a mechanical fastening tape 2 as shown in the figure, the mechanical fastening element paired with the mechanical fastening tape is provided on the outer surface of the elastic elastic member 20 or another sheet 21 (on the outer surface). This is provided on the outer surface of FIG. 3 and FIG. 4 and constitutes a connecting means.

さて、かかる連結式おむつにおいて、吸収性本体10のバックシート12と弾性伸縮部材20とがたとえばホットメルト接着剤31によって接合されることにより、弾性伸縮部材20、20は吸収性本体10の腹側及び背側のそれぞれの端部において固定されている。吸収性本体10の表面シート11と弾性伸縮部材20とを接合することも可能である。
これらの弾性伸縮部材20、20と吸収性本体10との連結固定は、ホットメルト接着剤によるのが望ましいが、それぞれオス要素とメス要素との組み合わせによるメカニカルファスナーにより連結固定することもできる。
かかる形態では、止着手段としての多数のオス要素2Aを有するメカニカルファスナーテープ2、2を腹側に持ち込み腹側の弾性伸縮部材20の裏面に対して連結すると、図3に示すように、弾性伸縮部材20の長手方向の伸長F0に伴って、弾性伸縮部材20が縦方向に収縮する。その際、弾性伸縮部材20と吸収性本体10の前後方向端部とをそれぞれ連結固定しているので、弾性伸縮部材20の縦方向の収縮が、図3及び図4の矢印Fのように、吸収性本体10の股下部を前後方向に持ち上げる(吊り上げる)ように作用する。
その結果、吸収性本体10が着用者の肌側に接近または密着するようになり、股下部における横漏れを防止する。また、弾性伸縮部材20の伸長に伴う復元力が、ウエスト回りを締め付け、前後漏れ防止効果が高いものとなる。
そして、着用者が座ると胴回りが膨らむことにより、弾性伸縮部材20の伸長に伴って、吸収性本体10が股部に引き寄せられ、隙間ができにくい。また、個人差で股間がゆるくなるようにあてた場合でも、止着手段、たとえばテープを引っ張って止着する際に、吸収性本体が股間に引き寄せられるため、股間の緩みで漏れが生じることが少ない。
仮に、着用後に着用者の動きなどによって、おむつがずれ落ちたとしても、胴回りの周長は腰部から臀部に下がるに従って大きくなるため、弾性伸縮部材20は横方向にさらに伸長され、吸収性本体10の股下部を前後方向にさらに持ち上げる(吊り上げる)ように力が作用するので、吸収性本体10が着用者の肌側に接近または密着する状態を維持できる。
Now, in such a connected diaper, the elastic elastic members 20 and 20 are joined to the abdominal side of the absorbent main body 10 by joining the back sheet 12 of the absorbent main body 10 and the elastic elastic member 20 by, for example, a hot melt adhesive 31. And fixed at each end of the dorsal side. It is also possible to join the top sheet 11 of the absorbent main body 10 and the elastic elastic member 20.
These elastic elastic members 20 and 20 and the absorbent main body 10 are preferably connected and fixed by a hot melt adhesive, but can also be connected and fixed by mechanical fasteners each of which is a combination of a male element and a female element.
In such a form, when the mechanical fastener tapes 2 and 2 having a large number of male elements 2A as fastening means are brought into the abdomen and connected to the back surface of the elastic elastic member 20 on the abdomen, as shown in FIG. The elastic elastic member 20 contracts in the vertical direction along with the extension F0 of the elastic member 20 in the longitudinal direction. At that time, since the elastic elastic member 20 and the front-rear direction end of the absorbent main body 10 are respectively connected and fixed, the vertical contraction of the elastic elastic member 20 is as indicated by an arrow F in FIGS. The crotch part of the absorptive main body 10 acts so as to be lifted (lifted) in the front-rear direction.
As a result, the absorptive main body 10 comes close to or closely contacts the wearer's skin side, thereby preventing side leakage at the crotch. Moreover, the restoring force accompanying the expansion | extension of the elastic expansion-contraction member 20 tightens a waist periphery, and becomes a thing with a high front-and-back leak prevention effect.
When the wearer sits down, the waistline swells, and as the elastic elastic member 20 expands, the absorbent main body 10 is attracted to the crotch portion, making it difficult to form a gap. Even when the crotch is loosened due to individual differences, when the fastening means, for example, by pulling the tape, the absorbent main body is attracted between the crotch, so that leakage may occur due to the loosening of the crotch. Few.
Even if the diaper slips down due to the movement of the wearer after wearing, the circumference of the waistline increases as it falls from the waist to the buttocks, so the elastic elastic member 20 is further extended in the lateral direction and the absorbent main body 10 Since the force acts so as to further lift (hang) the crotch part in the front-rear direction, it is possible to maintain the state in which the absorbent main body 10 approaches or closely contacts the wearer's skin side.

<第2の実施の形態>
図5〜図8は第2の実施の形態を示したものである。図1において、Xが横方向、Yが前後方向をそれぞれ示し、前後方向Yの中間は股下部Lとなっている。股下部Lは脚周りに該当する前後方向のおむつの中間領域である。
1は裏面側に位置する、たとえば2枚の不織布からなる外装シートであり、その外装シート1の背側両側に止着手段、実施の形態では多数のオス要素2Aを有するメカニカルファスナーテープ2、2が、たとえば外装シート1、1の間に固定され、これらのメカニカルファスナーテープ2、2は、腹側に持ち込み外装シート1の腹側に予め設けられたメス要素を有するターゲットテープ3、あるいはターゲットテープ3なしで外装シート1の裏面自体がメス要素を構成する不織布とすることで対象の止着位置とした領域に連結される。したがって、第2の実施の形態では、メカニカルファスナーテープ2、2の関係で、ターゲットテープ3が連結手段を構成している例である。
外装シート1の内面側には、表面側から体液を受け入れて保持し裏面側への漏れを防止する吸収性本体10が設けられている。
<Second Embodiment>
5 to 8 show a second embodiment. In FIG. 1, X indicates a lateral direction, Y indicates a front-rear direction, and the middle of the front-rear direction Y is a crotch L. The crotch L is an intermediate region of the diaper in the front-rear direction corresponding to the periphery of the leg.
1 is an exterior sheet made of, for example, two non-woven fabrics located on the back surface side, and is a fastening means on both back sides of the exterior sheet 1, and mechanical fastener tapes 2 and 2 having a large number of male elements 2A in the embodiment. For example, these mechanical fastener tapes 2 and 2 are fixed between the exterior sheets 1 and 1, and the target tape 3 or the target tape having a female element that is brought in on the stomach side and provided in advance on the stomach side of the exterior sheet 1. The back surface itself of the exterior sheet 1 without using 3 is connected to the region where the target is fixed by using the nonwoven fabric constituting the female element. Therefore, in 2nd Embodiment, the target tape 3 is an example which comprises the connection means by the relationship of the mechanical fastener tapes 2 and 2. FIG.
On the inner surface side of the exterior sheet 1, an absorbent main body 10 that receives and holds body fluid from the front surface side and prevents leakage to the back surface side is provided.

さて、かかる連結式おむつにおいて、本発明においては、背側及び腹側における、前記連結手段による横方向X締め付け作用領域(連結の結果、前後に締め付け作用領域が生じる)に、伸長時に縦方向に収縮する弾性伸縮部材20、20をそれぞれ外装シート1の背側及び腹側において、ホットメルト接着剤30により横方向Xに固定してある。
また、弾性伸縮部材20、20と吸収性本体10の前後方向Y両端部とは、ホットメルト接着剤31により連結固定してある。
弾性伸縮部材20、20の外装シート1への固定、あるいは吸収性本体10との連結固定は、ホットメルト接着剤30、31によるのが望ましいが、それぞれオス要素とメス要素との組み合わせによるメカニカルファスナーにより連結固定することもできる。
さらに、実施の形態では、吸収性本体10は前記連結固定領域を除く前後方向Y中間領域の実質的に全体が外装シート10と固定関係にないものとしてある。ただし、吸収性本体10の前後方向Y中間領域、股下部Lの前後方向一部を部分的に固定することを排除するものではない。
かかる形態では、止着手段としてのメカニカルファスナーテープ2、2を腹側に持ち込み外装シート10の腹側と連結すると、図7に示すように、弾性伸縮部材20の長手方向の伸長F0に伴って、弾性伸縮部材20が縦方向に収縮する。その際、弾性伸縮部材20と吸収性本体10の前後方向端部とをそれぞれ連結固定しているので、しかも、吸収性本体10は前記連結固定領域を除く前後方向中間領域の実質的に全体が外装シート1と固定関係にないので、弾性伸縮部材20の幅方向の収縮が、図7及び図8の矢印Fのように、吸収性本体10の股下部を前後方向に持ち上げる(吊り上げる)ように作用する。
その結果、図8に示すように(図8においては、吸収性本体10を概括的に図示してある。)、吸収性本体10が着用者の肌側に接近または密着するようになり、股下部Lにおける横漏れを防止する。また、弾性伸縮部材20の伸長に伴う復元力が、ウエスト回りを締め付け、前後漏れ防止効果が高いものとなる。
仮に、着用後に着用者の動きなどによって、おむつがずれ落ちたとしても、胴回りの周長は腰部から臀部に下がるに従って大きくなるため、弾性伸縮部材20は横方向にさらに伸長され、吸収性本体10の股下部を前後方向にさらに持ち上げる(吊り上げる)ように力が作用するので、吸収性本体10が着用者の肌側に接近または密着する状態を維持できる。
Now, in this connection type diaper, in the present invention, in the dorsal and abdominal sides, in the lateral X tightening action region by the connecting means (the tightening action region is generated in the front and rear as a result of the connection), in the longitudinal direction when extended. The elastic elastic members 20 and 20 that are contracted are fixed in the lateral direction X by a hot melt adhesive 30 on the back side and the belly side of the exterior sheet 1, respectively.
Further, the elastic elastic members 20, 20 and both ends in the front-rear direction Y of the absorbent main body 10 are connected and fixed by a hot melt adhesive 31.
The elastic stretch members 20 and 20 are fixed to the exterior sheet 1 or connected and fixed to the absorbent main body 10 by hot melt adhesives 30 and 31, but each is a mechanical fastener using a combination of male and female elements. Can also be connected and fixed.
Furthermore, in the embodiment, the absorbent main body 10 is assumed to have substantially no fixed relationship with the exterior sheet 10 in substantially the entire Y-intermediate area in the front-rear direction excluding the connection fixing area. However, it does not exclude that the front-rear direction Y intermediate region of the absorbent main body 10 and a part of the crotch L are partially fixed in the front-rear direction.
In such a form, when the mechanical fastener tapes 2 and 2 as fastening means are brought to the abdomen side and connected to the abdomen side of the exterior sheet 10, as shown in FIG. 7, along with the longitudinal extension F 0 of the elastic elastic member 20. The elastic elastic member 20 contracts in the vertical direction. At that time, since the elastic elastic member 20 and the front-rear direction end of the absorbent main body 10 are respectively connected and fixed, the absorbent main body 10 is substantially entirely in the front-rear direction intermediate region excluding the connection fixing region. Since there is no fixed relationship with the exterior sheet 1, the shrinkage in the width direction of the elastic elastic member 20 lifts (lifts) the crotch part of the absorbent main body 10 in the front-rear direction as indicated by the arrow F in FIGS. Works.
As a result, as shown in FIG. 8 (in FIG. 8, the absorbent main body 10 is schematically shown), the absorbent main body 10 comes close to or closely contacts the wearer's skin side, and the inseam Side leakage at the part L is prevented. Moreover, the restoring force accompanying the expansion | extension of the elastic expansion-contraction member 20 tightens a waist periphery, and becomes a thing with a high front-and-back leak prevention effect.
Even if the diaper slips down due to the movement of the wearer after wearing, the circumference of the waistline increases as it falls from the waist to the buttocks, so the elastic elastic member 20 is further extended in the lateral direction and the absorbent main body 10 Since the force acts so as to further lift (hang) the crotch part in the front-rear direction, it is possible to maintain the state in which the absorbent main body 10 approaches or closely contacts the wearer's skin side.
