Description

本発明は、ショーツ（男女用を問わない）、テープ式おむつまたはパンツ型おむつなどの外装体の使用面側に吸収パッドをあてがい使用するパッド型おむつ構造に関する。 The present invention relates to a pad-type diaper structure in which an absorbent pad is applied to a use surface side of an exterior body such as shorts (for men and women), a tape-type diaper, or a pants-type diaper.

ショーツなどの下着の使用面側に吸収パッドをあてがい使用することが行われている。しかし、着用者の動きによってショーツはずれ落ちたりすることが多く、吸収パッドと肌との間から漏れることが多い。
他方、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主に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。成人の場合には、自身による着用の可否によって使い分けが行われている。
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、乳児の例を取って説明すると、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、ウエスト回り方向に伸縮する機能は有しない。
特許第３８１１０８６号 The use of an absorbent pad on the use side of underwear such as shorts has been carried out. However, the shorts often fall off due to the movement of the wearer, often leaking from between the absorbent pad and the skin.
On the other hand, so-called tape-type (disposable) diapers are mainly used for infants, whereas pants-type diapers are mainly intended for infants. In the case of an adult, it is properly used depending on whether or not it can be worn by itself.
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, taking an example of an infant, a wearer (mother or the like) 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 the function of expanding and contracting in the direction around the waist.
Japanese Patent No. 3811086

したがって、本発明の主たる課題は、吸収パッドを使用する場合において、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パッド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パッド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パッド構造を提供することにある。 Therefore, when the absorbent pad is used, the main problem of the present invention is that the waist is brought into close contact with the elastic elastic member of the waist part, and the absorbent pad is brought into close contact with or close to the skin as the elastic elastic member of the waist part is extended. In addition, it is an object of the present invention to provide a pad structure that can maintain the absorbent pad 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。

ことを特徴とするパッド型おむつ構造。 The present invention that has solved the above problems is as follows.
<Invention of Claim 1>
For the exterior body that is configured on the back surface side and at least the waist part can be expanded and contracted in the lateral direction, an absorbent pad that receives and holds body fluid from the front surface side and prevents leakage to the back surface side is used when the exterior body is in use. In the pad type diaper structure that is connected and fixed to the use side of the body,
In the crotch part of the middle part in the width direction of the elastic elastic member which is in the shape of a strip that is longer in the lateral direction than the absorbent pad and contracts in the longitudinal direction when stretched in the lateral direction at the respective end portions on the ventral side and the back side of the absorbent pad The end of the
In use, the elastic elastic member is connected and fixed to the use surface side of the back and abdominal waist portions of the exterior body by connecting and fixing means at both lateral ends thereof, and the width direction intermediate portion of the elastic elastic member is used. The crotch side of the part is not fixed ,
The absorbent pad rather Do substantially entirely fixed relation with the outer body in the front-rear direction intermediate region excluding the connection fixing region,
When the exterior body is worn, the elastic elastic member is pulled in the lateral direction together with the exterior body and contracts in the longitudinal direction, whereby the longitudinal contraction causes the crotch portion of the absorbent pad to move back and forth with respect to the exterior body. Configured to lift in the direction,
A pad-type diaper structure.

（作用効果）
本発明において、裏面側に位置し少なくともウエスト部分が横方向に伸縮可能に構成された外装体の代表例としては、ショーツなどの下着、テープ式おむつまたはパンツ型おむつである。
テープ式などの連結式おむつあるいはパンツ型おむつにおいて、予め外装体の脇部やウエスト回りに横方向に伸縮するウエスト伸縮部材が設けられている場合、着用時にその弾性伸縮部材の伸長力を開放したときに伸縮する。
いま、テープ式おむつを外装体とする例に沿ってその作用効果を説明する。
前記背側及び腹側における、連結手段としてのテープの止着による横方向締め付け作用領域に、吸収パッド使用時において、横方向に伸ばすと縦方向に収縮する弾性伸縮部材２０（図面参照）をそれぞれ外装体１に横方向に連結固定する。したがって、止着テープを腹側に持ち込み外装体１の腹側と連結した状態でおむつを着用すると、図３に示すように、弾性伸縮部材２０は横方向に引っ張られ、縦方向に収縮する。その際、弾性伸縮部材２０と吸収パッド１０の前後方向端部とをそれぞれ固定しているので、しかも、吸収パッド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体１と固定関係にないので、弾性伸縮部材２０のその幅方向（前後方向）の収縮が、図３〜図５の矢印Ｆのように、吸収パッド１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、吸収パッド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（外装体）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、吸収パッド１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、吸収パッド１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を前後にそれぞれ設けたので、前後方向一方に設ける場合に比較して、吸収パッド１の股下部を前後方向に持ち上げる量が多くなり、吸収パッド１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。
パンツ式おむつの場合には、着用時において、少なくともウエスト回りに設けられたウエスト伸縮部材に抗してウエスト部分を拡開すると、同様に、弾性伸縮部材２０の横方向の伸長に伴って、弾性伸縮部材２０が縦方向に収縮する。その結果、吸収パッド１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。
もちろん、ウエスト部分に予め伸縮部材などにより伸縮可能に設けられたショーツなどの下着においても、その装着時に収縮により、吸収パッド１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。
従来、通常のパッド型おむつ構造において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、吸収性パッドが股部に引き寄せられ、隙間ができにくい。 (Function and effect)
In the present invention, typical examples of an exterior body that is located on the back surface side and is configured such that at least a waist portion can be expanded and contracted in the lateral direction are underwear such as shorts, a tape-type diaper, or a pants-type diaper.
In a connected diaper such as a tape type or a pants-type diaper, when a waist elastic member that expands and contracts in the lateral direction around the side of the exterior body and around the waist is provided in advance, the extension force of the elastic elastic member is released when worn. Sometimes it stretches.
Now, the operation and effect will be described along an example in which a tape-type diaper is used as an exterior body.
Elastic stretching members 20 (refer to the drawings) that contract in the longitudinal direction when stretched in the lateral direction when the absorbent pad is used in the lateral tightening action region by fastening the tape as the connecting means on the dorsal side and the ventral side, respectively. The exterior body 1 is connected and fixed in the lateral direction. Therefore, when the diaper is worn while bringing the fastening tape into the abdomen and connected to the abdomen of the exterior body 1, the elastic elastic member 20 is pulled in the lateral direction and contracted in the longitudinal direction as shown in FIG. At this time, since the elastic elastic member 20 and the front and rear end portions of the absorbent pad 10 are respectively fixed, the absorbent pad 10 is substantially entirely in the front and rear intermediate region excluding the connection fixing region. Since the elastic expansion / contraction member 20 is contracted in the width direction (front-rear direction), the crotch portion of the absorbent pad 1 is lifted (lifted) in the front-rear direction as indicated by an arrow F in FIGS. Act on.
As a result, the absorbent pad 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-back leak prevention effect.
Even if the diaper (exterior body) slips off 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, Since the force acts so as to further lift (lift) the crotch part of the absorbent pad 1 in the front-rear direction, it is possible to maintain the state where the absorbent pad 1 approaches or closely contacts the wearer's skin side.
Moreover, in the said form, since the elastic expansion-contraction member 20 was each 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 absorption pad 1 in the front-back direction increases, and the absorption pad 1 wears. It comes to approach or closely adhere to a person's skin side suitably.
In the case of a pants-type diaper, when the waist portion is expanded against the waist elastic member provided at least around the waist at the time of wearing, similarly, the elastic elastic member 20 is elastic along with the lateral extension. The elastic member 20 contracts in the vertical direction. As a result, the crotch portion of the absorbent pad 1 acts to lift (lift) in the front-rear direction.
Of course, even underwear such as shorts provided on the waist part in advance by an elastic member or the like, the crotch part of the absorbent pad 1 acts to be lifted (lifted) in the front-rear direction by contraction at the time of wearing.
Conventionally, in a normal pad-type diaper structure, when the wearer sits, a gap is easily formed around the legs. However, according to the structure of the present invention, when the wearer sits, the waistline swells, so that the elastic elastic member expands. Thus, the absorbent pad is attracted to the crotch, making it difficult to form a gap.

＜請求項３項記載の発明＞
前記外装体は、ショーツ、テープ式おむつまたはパンツ型おむつである請求項１又は２記載のパッド型おむつ構造。 <Invention of Claim 3 >
The outer body, shorts, pad type diaper structure according to claim 1 or 2, wherein a tape-type diaper or pant diaper.

本発明においては、要すれば、吸収パッドを使用する場合において、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、装着時の弾性伸縮部材の伸長あるいは着用者が座った際に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、吸収パッドが股部に引き寄せられ、隙間ができにくいものとなる。しかも外装体が股下側にずれ落ちたとしても吸収パッド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での漏れを防止することができる。 In the present invention, when using an absorbent pad, if necessary, the elastic elastic member may be tightened in close contact with the restoring force of the elastic elastic member, and the elastic elastic member may be stretched when worn or when the wearer sits down. With the expansion of the elastic elastic member due to the swelling of the waistline, the absorbent pad is attracted to the crotch portion, making it difficult to form a gap. In addition, even if the exterior body slips down to the crotch side, the absorbent pad can still be kept in close contact with or close to the skin. Accordingly, leakage at the waist and the crotch 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、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外装体であり、外装体がおむつである場合、その代表例は、不織布などからなる透液性表面シート１Ａ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裏面シート１Ｂと、それらの間に介在された吸収体１３とを備える形態を挙げることができる。
図示のように、テープ式おむつが外装体１である場合、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体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なしで外装体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。実施の形態では、メカニカルファスナーテープ２、２と、ターゲットテープ３とが連結手段を構成している。この連結手段は、おむつの背側及び腹側を着用者に対し横方向Ｘに締め付ける。なお、図示していないが、外装体１の少なくともウエスト部分に弾性伸縮部材を予め設けておき、ウエスト部分を伸縮可能にしておくのが望ましい。 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 the horizontal direction, Y indicates the 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 body that is located on the back surface side, accepts and holds body fluid from the front surface side, and prevents leakage to the back surface side. When the exterior body is a diaper, a representative example thereof is a liquid-permeable property composed of a nonwoven fabric or the like. Examples include a top sheet 1A, a liquid-impermeable plastic back sheet 1B such as polyethylene, and an absorber 13 interposed therebetween.
As shown in the figure, when the tape-type diaper is the exterior body 1, the fastening means, and mechanical fastener tapes 2 and 2 having a large number of male elements 2A in the embodiment are fixed to both sides of the back side. 2 and 2 shall be the target tape 3 having a female element previously provided on the abdomen side of the exterior body 1 to be brought into the stomach side, or the nonwoven fabric in which the back surface of the exterior body 1 itself constitutes the female element without the target tape 3. To be connected to the area where the target is positioned. In embodiment, the mechanical fastener tapes 2 and 2 and the target tape 3 comprise the connection means. This connection means fastens the back side and the abdomen side of the diaper in the lateral direction X with respect to the wearer. Although not shown, it is desirable to provide an elastic elastic member in advance at least on the waist of the exterior body 1 so that the waist can be expanded and contracted.

外装体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パッド１０が設けられている。
吸収パッド１０の形態は適宜でよいが、たとえば不織布からなる内面シート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裏面シート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。この例示の吸収体１３の素材は、外装体１の吸収体１Ｃの素材としても使用できる。 On the inner surface side of the outer package 1, there is provided an absorption pad 10 that receives and holds body fluid from the front surface side and prevents leakage to the back surface side.
The form of the absorbent pad 10 may be appropriate. For example, the inner pad 11 made of nonwoven fabric, the liquid back-impervious plastic back sheet 12 such as polyethylene, and the absorber 13 interposed between them are listed. be able to. 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 material of the illustrated absorber 13 can also be used as the material of the absorber 1C of the exterior body 1.

吸収パッド１０には、必要により、バリヤーカフス１４及び又はガスケットカフス（図示せず）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。
本発明においては、横方向に長い帯状で、横方向に伸ばすと縦方向に収縮する弾性伸縮部材２０、２０を、吸収パッド１０の前後方向Ｙ両端部に対して、ホットメルト接着剤３１などによりそれぞれ固定してある。横方向（図１におけるＸ方向）における弾性伸縮部材２０、２０の長さは、前述の持上げる力を大きく作用させるため、図示例のように、横方向における吸収パッド１０の長さよりも長くする。
また、弾性伸縮部材２０、２０の長手方向（外装体の横方向）の両端部には、連結固定手段３０が設けられている。図示例の連結固定手段３０としては、吸収パッド１０の裏面に予め設けられたホットメルト接着剤である。
このホットメルト接着剤３０の位置は、図６にも示すとおりであるが、その他、図７のように横方向に沿って、図８のようにＬ字状のものを対向する形態などで適宜配置できる。ホットメルト接着剤３０を横方向に間欠的に設けることもできる。
他方で、弾性伸縮部材２０、２０の配設位置としては、かかる連結式おむつにおいては、背側及び腹側における、前記連結手段（メカニカルファスナーテープ２）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、横方向（それ自身では長手方向）に沿って配設するのが望ましい。
弾性伸縮部材２０、２０の外装体１への固定、あるいは吸収パッド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。 If necessary, the absorbent pad 10 may be provided with a barrier cuff 14 and / or a gasket cuff (not shown). 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.
In the present invention, the elastic elastic members 20, 20 that are long in the lateral direction and contract in the longitudinal direction when stretched in the lateral direction are attached to the both ends in the front-rear direction Y of the absorbent pad 10 by the hot melt adhesive 31 or the like. Each is fixed. The lengths of the elastic elastic members 20 and 20 in the lateral direction (X direction in FIG. 1) are made longer than the length of the absorbent pad 10 in the lateral direction as shown in the example in order to exert the above-described lifting force greatly. .
Moreover, the connection fixing means 30 is provided in the both ends of the longitudinal direction (lateral direction of an exterior body) of the elastic expansion-contraction members 20 and 20. FIG. The connection fixing means 30 in the illustrated example is a hot melt adhesive provided in advance on the back surface of the absorbent pad 10.
The position of the hot-melt adhesive 30 is as shown in FIG. 6 as well, but in addition to the L-shaped one as shown in FIG. Can be placed. The hot melt adhesive 30 can also be provided intermittently in the lateral direction.
On the other hand, as the arrangement position of the elastic elastic members 20, 20, in such a connection type diaper, a lateral X tightening action region (result of connection) by the connection means (mechanical fastener tape 2) on the back side and the abdomen side. It is desirable to arrange them along the lateral direction (in the longitudinal direction itself) in the longitudinal direction.
The elastic expansion members 20 and 20 are preferably fixed to the exterior body 1 or connected and fixed to the absorbent pad 10 by hot-melt adhesives 30 and 31, respectively, by mechanical fasteners by combinations of male and female elements, respectively. It can also be connected and fixed.

さらに、吸収パッド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体１０と固定関係にないものとしてある。ただし、吸収パッド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、吸収パッド１０を外装体１の使用面側に持ち込み、好ましくは、弾性伸縮部材２０の長手方向両端を持って伸長させた状態で、外装体１の表面シート１Ａに接着させる。その結果、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が幅方向に収縮する。その後に、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体１０の腹側と連結すると、図３に示すように、弾性伸縮部材２０の長手方向にさらに伸長力Ｆ０をもって伸長され、その伸長に伴って、弾性伸縮部材２０が幅方向にさらに収縮する。その際、弾性伸縮部材２０と吸収パッド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、吸収パッド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体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３〜図５の矢印Ｆのように、吸収パッド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。 Further, the absorbent pad 10 is assumed to have substantially no fixed relationship with the exterior body 10 in the front-rear direction Y intermediate region excluding the connection fixing region. However, it does not exclude that the front-rear direction Y intermediate region of the absorbent pad 10 and a part of the crotch L are partially fixed in the front-rear direction.
In such a form, the absorbent pad 10 is brought into the use surface side of the exterior body 1, and preferably adhered to the topsheet 1 A of the exterior body 1 in a state of being stretched with both ends in the longitudinal direction of the elastic elastic member 20. As a result, as shown in FIG. 3, the elastic elastic member 20 contracts in the width direction along with the longitudinal extension F 0 of the elastic elastic member 20. Thereafter, 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 body 10, as shown in FIG. 3, the elastic expansion member 20 is further extended with an extension force F0 in the longitudinal direction. In accordance with the extension, the elastic elastic member 20 further contracts in the width direction. At that time, since the elastic expansion / contraction member 20 and the front and rear end portions of the absorbent pad 10 are connected and fixed, respectively, the absorbent pad 10 is substantially entirely in the front and rear intermediate region excluding the connection and fixing region. Since the elastic expansion / contraction member 20 is contracted in the width direction, the crotch part of the absorbent pad 10 is lifted (lifted) in the front-rear direction as indicated by an arrow F in FIGS.

その結果、図５に示すように、吸収パッド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、吸収パッド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、吸収パッド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。
上記例では、吸収パッド１０の外装体１への連結固定時に弾性伸縮部材２０を伸長させ、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体１０の腹側と連結する段階でも、弾性伸縮部材２０を伸長させるものとした。しかし、後者の伸長度合いは前者のものと比較してあまり大きくないので、主に前者の伸長に頼る形態が望ましい。
図９は、図１の形態を概念的に図示し、弾性伸縮部材２０位置関係を判り易くしたものである。 As a result, as shown in FIG. 5, the absorbent pad 10 comes close to or in close contact with the wearer's skin side, thereby preventing side leakage at the crotch L. 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-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 pad 10 Since force acts so as to further lift (lift) the crotch part in the front-rear direction, it is possible to maintain a state in which the absorbent pad 10 approaches or closely contacts the wearer's skin side.
In the above example, the elastic elastic member 20 is extended at the time of connecting and fixing the absorbent pad 10 to the exterior body 1, and the elastic elastic member 20 is connected to the abdominal side of the exterior body 10 by bringing the mechanical fastener tapes 2 and 2 to the abdomen side. 20 was extended. However, since the degree of extension of the latter is not so large as compared with the former, it is desirable to mainly rely on the former extension.
FIG. 9 conceptually illustrates the form of FIG. 1 and facilitates understanding of the positional relationship of the elastic elastic member 20.

図９の図示法に準じて図示した図１０及び図１１に示すように、背側及び腹側における弾性伸縮部材２０、２０の形状を異なるものとすることができる。
図１０の例では、腹側における弾性伸縮部材２０の幅を背側における前記弾性伸縮部材２０の幅より幅狭く、かつ短くし、腹への過度の圧迫を可能な限り防止したものである。
図１１の例では、逆に、腹側における弾性伸縮部材２０の幅が背側における弾性伸縮部材２０の幅より幅広とし、乳児の腹は太鼓状であり、腹側においてずれ落ち易いことに鑑み、前後方向に持ち上げる量を多くするようにしたものである。
