Description

本発明は、止着タイプ使い捨ておむつに関するものである。 The present invention relates to a fastening type disposable diaper.

使い捨ておむつは、大きく分けてパンツタイプとテープタイプ（止着タイプの代表的形態）に分けられ、パンツタイプは主に立位で装着され、テープタイプは主に仰臥位で装着される。しかし、特に子供の場合、成長の過程で立位をとることが出来ない状態では、パンツタイプの着用はテープタイプの着用と比較して困難であり、また、頻繁に寝返りをうつ状態や四つん這いの状態では、テープタイプの着用において、テープを適した位置に固定することが困難な状況が生じうる。 Disposable diapers are roughly divided into a pants type and a tape type (a typical form of fastening type). The pants type is mainly worn in a standing position, and the tape type is mainly worn in a supine position. However, especially in the case of children, when they are unable to stand in the process of growth, wearing pants is more difficult than wearing tape, and they are more likely to turn over frequently or crawl on all fours. In the state, it may be difficult to fix the tape in a suitable position when wearing the tape type.

特許文献１には、予めパンツタイプ使い捨ておむつのように形成されているもののテープタイプ使い捨ておむつのように展開可能なおむつが開示されている。しかし、このような使い捨ておむつにおいても、パンツタイプとしての使用またはテープタイプとしての使用のいずれかの使用に限られ、上記の着用の困難性を解消し得るものではなかった。 Patent Document 1 discloses a diaper that can be developed like a tape-type disposable diaper, although it is formed like a pants-type disposable diaper in advance. However, even in such disposable diapers, the use is limited to either use as a pants type or use as a tape type, and the above-mentioned difficulty in wearing cannot be solved.

特許文献２には、テープタイプの使い捨ておむつ本体の胴回り内側に仮止め帯を設け、立位での着用を容易とした使い捨ておむつが開示されている。しかし、特許文献２に開示される使い捨ておむつは、胴回りの肌に直接触れる状態で仮止め帯を装着するため、着用感が劣る、という問題があった。また、当該使い捨ておむつは、乳幼児のように着用者が動き易い場合に適切な締め付け圧で装着することが困難であるといった問題点や、伏臥位や四つん這い状態での装着が困難であるといった問題点を有していた。 Patent Document 2 discloses a disposable diaper that is provided with a temporary fastening band on the inner side of the waist of a tape-type disposable diaper main body and that is easily worn in a standing position. However, the disposable diaper disclosed in Patent Document 2 has a problem that the wearing feeling is inferior because the temporary fastening band is attached in a state where the disposable diaper is in direct contact with the skin around the waist. In addition, the disposable diaper has a problem that it is difficult to wear it with an appropriate tightening pressure when the wearer is easy to move like an infant, and a problem that the disposable diaper is difficult to wear in a prone position or on all fours. Had.

そこで、本発明の主たる課題は、これらの問題点を解決することにある。 Therefore, the main problem of the present invention is to solve these problems.

上記課題を解決した本発明は次のとおりである。なお、本発明において、「前後方向」及び「縦方向」とは吸収性本体の長手方向と同一の方向を指し、「幅方向」及び「横方向」とは、おむつを展開状態で平置きした状態における、吸収性本体の長手方向と垂直の方向を指すものとする。また、「上下方向」とは、立位の着用状態における上下方向を示すものとする。 The present invention that has solved the above problems is as follows. In the present invention, “front-rear direction” and “longitudinal direction” refer to the same direction as the longitudinal direction of the absorbent main body, and “width direction” and “lateral direction” mean that the diaper is placed flat in an unfolded state. It shall refer to the direction perpendicular to the longitudinal direction of the absorbent body in the state. Further, the “vertical direction” indicates the vertical direction in a standing wearing state.

Fastening type disposable diaper characterized by that.

（作用効果）
本発明では、例えば次のような装着が可能となる。すなわち、先ず第１止着部を腹側部外面に係止することにより着用者の胴回りに対して緩く仮装着し、第２止着部は止着せずにおく。つまり、第１止着部は仮装着用であり、必ずしも係止部の正確な位置に係止される必要がなく、着用者が動く等、正確な作業が困難な場合でも容易に作業を行うことができる。この際、通常のテープタイプおむつのように、着用者におむつの吸収体部分をあてがった後に第１止着部を係止する他、予め第１止着部を係止した後にパンツタイプのように着用者に穿かせてもよい。脇部分に充分な隙間があれば、第１止着部を係止した状態で、容易に穿かせることが可能である。 (Function and effect)
In the present invention, for example, the following mounting is possible. That is, first, the first fastening part is temporarily attached to the wearer's waist by locking the abdomen side outer surface, and the second fastening part is left unfastened. In other words, the first fastening portion is for temporary mounting, and does not necessarily have to be locked at the exact position of the locking portion, and can easily work even when accurate work is difficult, such as when the wearer moves. Can do. At this time, like a normal tape type diaper, the first fastening part is locked after the absorbent part of the diaper is applied to the wearer. It may be worn by the wearer. If there is a sufficient gap in the side portion, it is possible to easily pierce with the first fastening portion locked.

しかる後、第２止着部を自身から第１止着部までの部位、若しくは腹側部分外面における第１止着部の係止部位より幅方向中央側の部位に係止することで、胴回りの締め付けが適切となるように増し締めを行う。既に、第１止着部による仮装着によっておむつの大まかな位置決めがなされているため、着用者が動く等、正確な作業が困難な場合でも、比較的容易に適切な増し締めが可能となる。 After that, by locking the second fastening part to the part from itself to the first fastening part, or to the part on the center side in the width direction from the fastening part of the first fastening part on the outer surface of the abdomen side, Perform additional tightening so that the tightening is appropriate. Since the rough positioning of the diaper has already been performed by provisional attachment using the first fastening portion, appropriate tightening can be performed relatively easily even when accurate work such as movement of the wearer is difficult.

＜請求項２記載の発明＞
前記身体への装着に際し、左右各側において、前記第１止着部を前記腹側部外面に係止するとともに、前記第２止着部を自身から前記第１止着部までの部位、若しくは前記腹側部分外面における前記第１止着部の係止部位より幅方向中央側の部位に係止するか、又は前記第２止着部を前記背側部分における第２止着部間の部位、若しくは反対側の第２止着部に係止するように構成した、請求項１記載の止着タイプ使い捨ておむつ。 <Invention of Claim 2>
When attaching to the body, the first fastening part is locked to the abdominal side outer surface on each of the left and right sides, and the second fastening part is a part from itself to the first fastening part, or A portion of the abdomen-side portion outer surface that is locked to a portion on the center side in the width direction from a locking portion of the first fixing portion, or the second fixing portion that is between the second fixing portions in the dorsal side portion. The fastening type disposable diaper according to claim 1, wherein the fastening type disposable diaper is configured to be locked to the second fastening part on the opposite side.

（作用効果）
このような構成とすることにより、第１止着部を腹側部分に係止した仮装着状態で第２止着部を係止する際、着用者が伏臥位、又は四つん這い状態等になっていても、第２止着部を、腹側ではなく背側に回して、背側部分における第２止着部間の部位若しくは反対側の第２止着部に係止することにより増し締めすることができ、適切な締め付け圧で装着することができる。 (Function and effect)
By adopting such a configuration, when the second fastening portion is locked in the temporary mounting state where the first fastening portion is locked to the abdominal side portion, the wearer is in a prone position, a four-sided state, or the like. However, the second fastening part is turned to the back side instead of the abdomen side, and tightened by engaging the part between the second fastening parts in the back side portion or the second fastening part on the opposite side. And can be mounted with appropriate clamping pressure.

前記背側部分における前記第２止着部間に、幅方向に弾性伸縮する弾性伸縮部を設けるとともに、
前記背側部分の左右各側における第１止着部と第２止着との間の部分のうち、第１止着側の部分に幅方向に弾性伸縮する弾性伸縮部を設け、第２止着部側の部分に幅方向に弾性伸縮しない非伸縮部を設けた、
請求項２記載の止着式タイプ使い捨ておむつ。 <Invention of Claim 3>
Between the second fastening part in the back side part, while providing an elastic stretch part that elastically stretches in the width direction,
Of the portion between the first fastening portion and the second fastening on the left and right sides of the back side portion, an elastic stretchable portion that elastically stretches in the width direction is provided on the first fastening side portion, and the second fastening A non-stretchable part that does not elastically stretch in the width direction is provided on the part on the wearing part side.
The fastening type disposable diaper according to claim 2.

（作用効果）
背側部分の幅方向全体にわたり幅方向に弾性伸縮する部分を設けると、第２止着部を腹側に回して係止する場合には第２止着部間の部分の弾性伸縮によりフィット性が向上し、第２止着部を背側に回して止着する場合には第１止着部と第２止着部との間の部分の弾性伸縮によりフィット性が向上する。しかし、その場合、第２止着部を腹側に回して第１止着部と第２止着部との間の部分に係止する場合、当該係止対象部分が弾性伸縮することにより係止力が低下する、あるいは係止し難くなるといったおそれがある。そこで、上述のように係止対象部分に非伸縮部を設け、フィット性及び係止性の両立を図るのが好ましい。 (Function and effect)
When a portion that elastically expands and contracts in the width direction is provided over the entire width direction of the back side portion, when the second fastening portion is turned to the ventral side and locked, the fit property is achieved by elastic stretching of the portion between the second fastening portions. When the second fastening part is turned to the back side and fastened, the fitting property is improved by elastic expansion and contraction of the portion between the first fastening part and the second fastening part. However, in that case, when the second fastening portion is turned to the ventral side and locked to the portion between the first fastening portion and the second fastening portion, the portion to be locked is elastically expanded and contracted. There is a risk that the stopping force is reduced or it becomes difficult to lock. Therefore, it is preferable to provide a non-stretchable portion in the portion to be locked as described above to achieve both fit and locking properties.

＜請求項４記載の発明＞
前記第１止着部と前記第２止着部とが互いに上下方向に重ならないようにそれぞれ配置された、請求項１〜３のいずれか１項に記載の止着式タイプ使い捨ておむつ。 <Invention of Claim 4>
The fastening type disposable diaper according to any one of claims 1 to 3, wherein the first fastening part and the second fastening part are arranged so as not to overlap each other in the vertical direction.

（作用効果）
第１止着部及び第２止着部をいずれも腹側の係止部に止着される場合、第１止着部の係止位置の横方向の位置が、第２止着部の係止位置と重なる場合があり得る。この場合、第１止着部と第２止着部の上下方向の位置も一致すると、第２止着部を係止部に係止することが困難となる。
本発明は、第１止着部と第２止着部の上下方向の位置をずらすことで、第２止着部を係止部に係止しやすい構成とした。 (Function and effect)
When both the first fastening portion and the second fastening portion are fastened to the abdominal locking portion, the lateral position of the locking position of the first fastening portion is related to the second fastening portion. It may overlap with the stop position. In this case, if the vertical positions of the first fastening portion and the second fastening portion also coincide, it becomes difficult to lock the second fastening portion to the locking portion.
In the present invention, the first fastening portion and the second fastening portion are shifted in the vertical direction so that the second fastening portion can be easily locked to the locking portion.

以上のとおり、本発明によれば、より容易に適切な締め付け圧での装着が可能となる、等の利点がもたらされる。 As described above, according to the present invention, there are advantages such that mounting with an appropriate tightening pressure can be performed more easily.

Note that, hereinafter, the stationary type disposable diaper according to the present invention is referred to as “disposable diaper” or “diaper”.

＜使い捨ておむつの実施形態＞
図１は、使い捨ておむつの実施形態の例を示す内面側平面図であり、図２は、その外面側平面図である。本実施形態のおむつは、中間部１０ｃと、その両側にそれぞれ張り出したサイドフラップ部１１，１２とを有し、装着者の胴回りに巻き付けられる帯状の胴回り部１０と、後端部が胴回り部１０の中間部１０ｃに連結され、背側から股間部を通り腹側までを覆うように装着される吸収性本体２０とから構成されている。なお、胴回り部１０と吸収性本体２０は、図示例の様な別体ではなく、一体として形成してもよい。 <Disposable diaper embodiment>
FIG. 1 is an inner surface side plan view showing an example of an embodiment of a disposable diaper, and FIG. 2 is an outer surface side plan view thereof. The diaper of this embodiment has an intermediate part 10c and side flap parts 11 and 12 projecting from both sides thereof, and a belt-like waist part 10 wound around the waist of the wearer, and a rear end part of the waist part 10 The absorptive main body 20 is connected to the intermediate portion 10c of the knives and is mounted so as to cover the back side through the crotch portion and the abdomen side. In addition, you may form the trunk periphery part 10 and the absorptive main body 20 as one body instead of separate bodies like the example of illustration.

吸収性本体２０は、製品の前後方向を長手とする長方形をなし、装着者の腹部、股間部および臀部を覆うように、製品の幅方向中央に沿って設けられており、その後端部２０Ｂは、ホットメルト接着等により胴回り部１０の中間部１０ｃの内面に着脱不能に固定されている。なお、吸収体本体２０の形状は、脚回りにそって括れを有する砂時計状であってもよい（図示せず）。 The absorbent main body 20 has a rectangular shape with the longitudinal direction of the product as the longitudinal direction, and is provided along the center in the width direction of the product so as to cover the wearer's abdomen, crotch portion, and buttocks, and the rear end portion 20B is It is fixed to the inner surface of the intermediate portion 10c of the waistline portion 10 by hot melt bonding or the like in a non-detachable manner. In addition, the shape of the absorber body 20 may be an hourglass shape having a constriction along the legs (not shown).

なお、吸収性本体２０の後端部２０Ｂを、粘着テープ、ターゲットテープ等を用いて胴回り部１０の中間部１０ｃの内面に着脱自在に連結することもできることは言うまでもない。おむつ交換時に汚れた吸収性本体２０のみを取り外し、新しい吸収性本体２０を取り付けるといった使い方ができるため好ましい。 In addition, it cannot be overemphasized that the rear-end part 20B of the absorptive main body 20 can also be connected to the inner surface of the intermediate part 10c of the waist part 10 using an adhesive tape, a target tape, etc. so that attachment or detachment is possible. This is preferable because only the absorbent main body 20 that is soiled during diaper replacement can be removed and a new absorbent main body 20 can be attached.

吸収性本体２０は、排泄物を受け止めて液分を吸収保持するものであり、図３〜図５に示されるように、身体に接触する使用面をなす液透過性トップシート２１と、液不透過性シート２３と、これらの間に介在された吸収体２２とを有し、周縁部においてトップシート２１および液不透過性シート２３がホットメルト接着等により接合された構造を有している。 The absorbent main body 20 receives the excrement and absorbs and holds the liquid component. As shown in FIGS. 3 to 5, the absorbent main body 20 has a liquid-permeable top sheet 21 that forms a use surface in contact with the body, and a liquid impermeable material. It has the structure which has the permeable sheet 23 and the absorber 22 interposed between these, and the top sheet | seat 21 and the liquid-impermeable sheet | seat 23 were joined by hot-melt adhesion etc. in the peripheral part.

また、吸収性本体２０の、胴回り部１０が取り付けられた端部と対向する端部において、胴回り部１０より小さく、伸縮性を有さない、フラップ形成部材を取り付けてもよい。このようにして、胴回り部１０の対向側の吸収性本体端部近傍の両側部に小さいフラップを設けると、止着式として装着する際に止着部と係止部の位置合せをする時の連結部のつまみ部とすることができ、好適である。 Moreover, you may attach the flap formation member which is smaller than the waist part 10 and does not have a stretching property in the edge part which opposes the edge part to which the waist part 10 was attached of the absorptive main body 20. In this way, when the small flaps are provided on both side portions in the vicinity of the end of the absorbent main body on the opposite side of the waistline portion 10, the position of the fastening portion and the locking portion when aligning as the fastening type is adjusted. It can be used as a knob portion of the connecting portion, which is preferable.

トップシート２１は、不織布、透液開口を有するフィルム、ネットシートなどから形成することができ、液不透過性シート２３は、ポリエチレンシート等のプラスチック製シートなどから形成することができる。液不透液性シートの外側には、エアスルー不織布、ポイントボンド不織布、スパンボンド不織布、ＳＭＳ不織布等の外装不織布が張り合わせられていてもよい（図示せず）。外装を不織布としない場合は、特に、シート表面に、別途フックが絡まるループが多数形成されたターゲットテープ２６を設け、これを連結部とする。ターゲットテープ２６は、図示例のように前後方向の中央より前側の部分等、一部に設けるのが好ましいが、全体にわたり設けることもできる。なお、外装を不織布とする場合であっても、ターゲットテープ２６を設けることが好ましい。 The top sheet 21 can be formed from a nonwoven fabric, a film having a liquid-permeable opening, a net sheet, or the like, and the liquid-impermeable sheet 23 can be formed from a plastic sheet such as a polyethylene sheet. An exterior nonwoven fabric such as an air-through nonwoven fabric, a point bond nonwoven fabric, a spunbond nonwoven fabric, and an SMS nonwoven fabric may be bonded to the outside of the liquid-impermeable sheet (not shown). When the exterior is not a non-woven fabric, in particular, a target tape 26 on which a number of loops with hooks are separately formed is provided on the sheet surface, and this is used as a connecting portion. The target tape 26 is preferably provided on a part of the front side of the center in the front-rear direction as in the illustrated example, but may be provided over the whole. Even when the exterior is a nonwoven fabric, it is preferable to provide the target tape 26.

吸収体２２としては、綿状パルプ等のように短繊維を積繊したものの他、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、セルロースアセテート等のトウ（繊維束）を開繊することにより形成することができる。吸収体２２には、必要に応じて高吸収性ポリマー（ＳＡＰ）を含有させたり、クレープ紙や不織布等により包んだりすることができる。 As the absorbent body 22, there can be used, for example, a fiber made of aggregates of filaments in addition to a fiber bundle of short fibers such as cotton-like pulp. The aggregate of filaments can be formed by opening a tow (fiber bundle) such as cellulose acetate. The absorbent body 22 may contain a superabsorbent polymer (SAP) as necessary, or may be wrapped with crepe paper or nonwoven fabric.

さらに、吸収性本体２０の幅方向両側部には、装着時においてトップシート２１に対して起立するバリヤーカフス３０，３０がそれぞれ設けられている。より詳細には、吸収性本体２０の両側部における長手方向全体にわたり、帯状をなすバリヤーシート３１の幅方向外側の縁部３１ａがホットメルト接着等によりトップシート２１表面に固定され、幅方向中央側の部分３１ｂは、吸収性本体２０の前後端部ではホットメルト接着等によりトップシート２１表面に固定され、長手方向中間部では非固定とされている。また、この非固定部分３１ｂは、先端側部分を折り返して基端側部分に張り合わせることにより二重構造とされ、この二重構造部分のシート間に、糸ゴム等の細長状弾性伸縮部材３２が伸張状態で長手方向に沿って挟持固定されている。使用時には、この弾性伸縮部材３２の収縮力によりバリヤーシート３１の非固定部分３１ｂがトップシート２１から離間するように起立し、その先端部が装着者の脚回りに密着する。その結果、トップシート２１上を伝って横方向に移動する排泄物が阻止され、横漏れが防止されるようになる。バリヤーシート３１としては撥水性不織布を好適に用いることができる。 Further, barrier cuffs 30, 30 that stand up with respect to the top sheet 21 at the time of wearing are provided on both sides in the width direction of the absorbent main body 20. More specifically, the edge 31a on the outer side in the width direction of the belt-like barrier sheet 31 is fixed to the surface of the top sheet 21 by hot-melt bonding or the like over the entire longitudinal direction on both sides of the absorbent main body 20, and the width direction center side The portion 31b is fixed to the surface of the top sheet 21 by hot-melt bonding or the like at the front and rear end portions of the absorbent main body 20, and is not fixed at the middle portion in the longitudinal direction. Further, the non-fixed portion 31b has a double structure by folding back and sticking the distal end portion to the proximal end portion. Between the sheets of the double structure portion, an elongated elastic elastic member 32 such as thread rubber is provided. Is clamped and fixed along the longitudinal direction in the stretched state. At the time of use, the non-fixed portion 31b of the barrier sheet 31 is erected away from the top sheet 21 by the contraction force of the elastic elastic member 32, and the tip portion thereof is in close contact with the wearer's leg. As a result, excrement moving in the lateral direction along the top sheet 21 is blocked, and side leakage is prevented. As the barrier sheet 31, a water-repellent nonwoven fabric can be suitably used.

胴回り部１０は、装着者の胴が通されるウエスト開口部から装着者の脚が通されるレッグ開口部までの部分となる帯状部材である。胴回り部１０は、製品幅方向において吸収性本体２０と対応する中間部１０ｃと、その両側に張り出した第１及び第２サイドフラップ部１１，１２とを有している。各サイドフラップ部１１，１２は、上下方向寸法がおむつの全長の１／５以上、特に１／４以上あると、着用者の胴回りの腹部から鼠蹊部にかけての範囲を広く覆うことができるため、優れた胴回りのフィット性が得られる。ただし、足回りがきつくなるため、１／３以上にはしないことが望ましい。なお、サイドフラップ部の形状が例えばテーパ状であるなどして、上下方向寸法が一様でない場合は、サイドフラップ部の幅方向中央における上下方向寸法を基準とする。また、各サイドフラップ部１１，１２は、収縮時の１．２〜３倍、特に１．５〜２．５倍まで伸張することが可能であると好ましく、伸張時の幅方向寸法が中間部１０ｃの１〜３倍、特に１．５〜２．５倍程度であると、胴回りの寸法調整がしやすいため、好ましい。なお、収縮時、伸張時の幅方向寸法の割合については、サイドフラップを引っ張らずに自然に収縮させた状態における幅方向寸法を１倍として算出するものとする。 The waistline portion 10 is a belt-like member that is a portion from a waist opening through which the wearer's torso is passed to a leg opening through which the wearer's leg is passed. The waistline portion 10 includes an intermediate portion 10c corresponding to the absorbent main body 20 in the product width direction, and first and second side flap portions 11 and 12 projecting on both sides thereof. Each of the side flaps 11 and 12 can cover a wide range from the abdomen to the buttocks around the wearer's waist when the vertical dimension is 1/5 or more of the total length of the diaper, particularly 1/4 or more. Excellent fit around the waist. However, since the undercarriage becomes tight, it is desirable not to make it more than 1/3. In addition, when the shape of a side flap part is a taper shape etc. and an up-down direction dimension is not uniform, it is based on the up-down direction dimension in the center of the width direction of a side flap part. Further, the side flap portions 11 and 12 are preferably 1.2 to 3 times, particularly 1.5 to 2.5 times that when contracted, and the width direction dimension when expanding is an intermediate portion. It is preferable that it is 1 to 3 times, particularly 1.5 to 2.5 times that of 10c, because the dimensions of the waistline can be easily adjusted. In addition, the ratio of the width direction dimension at the time of contraction and expansion is calculated by multiplying the width direction dimension in a state in which the side flap is naturally contracted without being pulled.

より詳細には、図６，７の各断面図から理解されるように、胴回り部１０はその全体にわたる本体シート１３を基本とし、部材の付加により各部に機能を持たせたものである。図示例においては、本体シート１３は、複数枚の不織布１３ａ，１３ｂを重ね合わせてホットメルト接着剤等により固定され、胴回り部の中間部１０ｃおよびサイドフラップ部１１，１２にわたり、弾性伸縮部材１４が幅方向（胴回り方向）に沿って伸張状態で断続的に挟持固定されている。本体シート１３を構成する不織布１３ａ，１３ｂとしては、十分な係合力を発揮する観点から、坪量が１０〜３５ｇ／ｍ²であるのが好ましく、また種類としてはエアスルー不織布、ポイントボンド不織布、スパンボンド不織布、ＳＭＳ不織布等が好適である。サイドストラップ部１１，１２のうち、弾性部材が幅方向に沿って配され、伸縮性を有する部分をサイド伸縮部１１ｘ，１２ｘ、弾性部材が配されない部分をサイド非伸縮部１１ｙ，１２ｙとする。サイド非伸縮部は、左右のサイドフラップにそれぞれ１箇所以上設けることが好ましい。 More specifically, as can be understood from the cross-sectional views of FIGS. 6 and 7, the waistline portion 10 is based on the main body sheet 13 over its entirety, and each portion has a function by adding members. In the illustrated example, the main body sheet 13 is formed by superimposing a plurality of nonwoven fabrics 13a and 13b and fixed by a hot melt adhesive or the like, and the elastic stretchable member 14 extends over the middle portion 10c and the side flap portions 11 and 12 of the waistline portion. It is clamped and fixed intermittently in a stretched state along the width direction (the waistline direction). As the nonwoven fabrics 13a and 13b constituting the main body sheet 13, it is preferable that the basis weight is 10 to 35 g / m ² from the viewpoint of exerting sufficient engagement force, and the types are air-through nonwoven fabric, point bond nonwoven fabric, span Bond nonwoven fabrics, SMS nonwoven fabrics and the like are suitable. Of the side strap portions 11 and 12, the elastic members are arranged along the width direction, the stretchable portions are the side stretchable portions 11x and 12x, and the portions where the elastic member is not placed are the side non-stretchable portions 11y and 12y. It is preferable to provide one or more side non-stretchable portions on the left and right side flaps.

なお、本体シート１３を構成する不織布を一重とし、弾性部材１４を設けない構成としてもよく、また、中間部１０ｃにおける本体シートと吸収体の不透液性シート２３との間にのみ弾性部材を配する構成としてもよい。 In addition, it is good also as a structure which does not provide the elastic member 14 in the nonwoven fabric which comprises the main body sheet | seat 13, and an elastic member is provided only between the main body sheet | seat in the intermediate part 10c, and the liquid-impermeable sheet 23 of an absorber. It is good also as a structure to distribute.

図示例においては、弾性伸縮部材１４が胴回り部１０の中間部１０ｃ全体に配されているが、中間部１０ｃでは弾性伸縮部材１４が切断されており、伸縮力が作用しないように構成されていてもよい。なお、弾性伸縮部材１４の配設領域は、吸収性本体２０の外形線にぴったり一致させる必要はなく、その近傍であれば、弾性伸縮部材１４は、吸収性本体２０と重なっていても離れていても構わない。 In the illustrated example, the elastic elastic member 14 is disposed on the entire intermediate portion 10c of the waist portion 10, but the elastic elastic member 14 is cut at the intermediate portion 10c so that the elastic force does not act. Also good. The area where the elastic elastic member 14 is disposed need not exactly match the outline of the absorbent main body 20, and if it is in the vicinity, the elastic elastic member 14 is separated even if it overlaps the absorbent main body 20. It doesn't matter.

弾性伸縮部材１４としては、糸ゴムや弾性発泡体の帯状物、フィルム状の弾性体、ネット状の弾性体等を使用できるが、多数の糸ゴムを胴回り方向に沿って複数本平行に設けるのが好ましい。具体的には、太さ３１０〜１２４０ｄｔｅｘ好ましくは３１０〜６２０ｄｔｅｘ程度の糸ゴムを、３〜６ｍｍの間隔で５〜１５本程度、伸張率１５０〜３５０％好ましくは２００〜３００％程度で固定するのが好ましい。ここでいう伸張率とは、弾性伸縮部材の自然長を１００％としたときの伸長時の長さの割合を意味する。 The elastic elastic member 14 may be a thread rubber or elastic foam band, a film-like elastic body, a net-like elastic body, or the like, but a plurality of thread rubbers are provided in parallel along the waist direction. Is preferred. Specifically, the thread rubber having a thickness of 310 to 1240 dtex, preferably about 310 to 620 dtex, is fixed at an interval of 3 to 6 mm at about 5 to 15 and an elongation ratio of 150 to 350%, preferably about 200 to 300%. Is preferred. The term “extension ratio” as used herein means the ratio of the length at the time of extension when the natural length of the elastic elastic member is 100%.

The second fastening portions 43 and 44 may be arranged at the same position in the vertical direction as the first fastening portions 41 and 42. However, as described later, the second fastening portions 43 and 44 can be easily locked to the ventral locking portion 26. In order to achieve this, it is more preferable to dispose them in the vertical direction. In the illustrated example, the first fastening parts 41 and 42 are arranged in the vicinity of the upper end of the side flap part, and the second fastening parts 43 and 44 are arranged in the vicinity of the lower end so that they do not overlap in the vertical direction. The first fastening parts 41 and 42 may be arranged near the lower end, and the second fastening parts 43 and 44 may be arranged near the upper end.

図示例においては、第２止着部４３，４４は、図示例のように本体の幅方向中央側の端部をサイドフラップに固着されており（図２）、また、第２止着部の止着手段４３ｘ，４４ｘは、第２止着部の内面側に配されている（図１１）。しかし、第２止着部４３，４４は、本体の幅方向端部側を固着してもよく、また、止着手段４３ｘ，４４ｘを外側面に配してもよい。 In the illustrated example, the second fastening portions 43 and 44 are fixed to the side flaps at the end in the width direction center side of the main body as shown in the illustrated example (FIG. 2). The fastening means 43x and 44x are arranged on the inner surface side of the second fastening part (FIG. 11). However, the second fastening portions 43 and 44 may be fixed to the end portions in the width direction of the main body, and the fastening means 43x and 44x may be disposed on the outer surface.

第２止着部４３，４４は、その止着手段４３ｘ，４４ｘの腹側の係止位置が、腹側の係止部２６または、胴回り部１０の非伸縮部１１ｙ，１２ｙとなる位置に配するのが好ましい。具体的には、第２止着部の固着位置を胴回り部１０の非伸縮部１１ｙ，１２ｙとするのが好ましい。 The second fastening parts 43, 44 are arranged at positions where the abdomen side locking positions of the fastening means 43x, 44x become the abdomen side locking part 26 or the non-stretchable parts 11y, 12y of the waistline part 10. It is preferable to do this. Specifically, it is preferable that the fixing position of the second fastening portion is the non-stretchable portions 11y and 12y of the waistline portion 10.

第１止着部、第２止着部のうち、少なくとも第２止着部は、エアスルー不織布、ポイントボンド不織布、スパンボンド不織布、ＳＭＳ不織布等の不織布とすることが好ましい。より好適には、第１止着部、第２止着部ともに不織布で構成されることが望ましい。 Of the first fastening portion and the second fastening portion, at least the second fastening portion is preferably a nonwoven fabric such as an air-through nonwoven fabric, a point bond nonwoven fabric, a spunbond nonwoven fabric, or an SMS nonwoven fabric. More preferably, it is desirable that both the first fastening part and the second fastening part are made of nonwoven fabric.

第１の実施形態に係るおむつについて、その着用時の形態の変化を図８〜１０に示す。まず、図８に示すように、透液性トップシート２３が内側になるように、吸収性本体２０の腹側部Ｆを背側部Ｂ側に折り返すことにより、係止部２６を上下方向の上部に移動する。次いで胴回り部１０のサイドフラップ部１１，１２を、それぞれ腹側からみて谷折りに上下方向にほぼ平行な線で折返し、端部の第１止着部４１，４２の止着手段４１ｘ，４２ｘを係止部２６に係止させ、仮止め状態とする（図９）。さらに、二つ折りになっているサイドフラップ部１１，１２をそれぞれ腹側からみて谷折りに上下方向にほぼ平行な線で折返し、第２止着部４３，４４の止着手段を係止部２６に止着させる（図１０）。これにより、腹側への係止によるおむつの着用者への固定が可能となる。 About the diaper which concerns on 1st Embodiment, the change of the form at the time of the wearing is shown to FIGS. First, as shown in FIG. 8, by folding the ventral side F of the absorbent main body 20 toward the back side B so that the liquid-permeable top sheet 23 is on the inside, the locking part 26 is moved in the vertical direction. Move to the top. Next, the side flap portions 11 and 12 of the waistline portion 10 are folded back along a valley fold along a line substantially parallel to the vertical direction when viewed from the abdominal side, and the fastening means 41x and 42x of the first fastening portions 41 and 42 at the ends are provided.

In the illustrated example of the first embodiment, the first fastening portion and the second fastening portion are arranged so as to be parallel to the width direction of the main body, but in the second embodiment shown in FIG. As described above, the second fastening parts 43 and 44 may be arranged obliquely so that the side flap parts 11 and 12 are arranged in the vicinity of the lower end in the vertical direction and the width direction end part side is at the upper part in the vertical direction. . In this embodiment, when the second fastening portion is locked to the ventral side locking portion 26, the leg opening is narrowed, so that it is suitable for a wearer with relatively thin legs. About another structure, it is a form similar to 1st Embodiment.

（第３の実施形態）
図１４に示す第３の実施形態においては、第２止着部４３，４４をサイドフラップ部１１，１２の上下方向下端部付近に配し、かつ、幅方向端部側が上下方向の下部にくるように斜めに配されている。この実施形態においては、第２止着部を腹側係止部２６に係止する場合において、脚部開口が広くなるため、比較的脚の太い着用者に適した形態となる。他の構成については、第１の実施形態と同様の形態である。 (Third embodiment)
In the third embodiment shown in FIG. 14, the second fastening parts 43 and 44 are arranged in the vicinity of the lower end in the vertical direction of the side flap parts 11 and 12, and the end in the width direction is at the lower part in the vertical direction. It is arranged diagonally. In this embodiment, when the second fastening portion is locked to the ventral side locking portion 26, the leg opening is widened, so that the configuration is suitable for a wearer with relatively thick legs. About another structure, it is a form similar to 1st Embodiment.

（第４実施形態）
図１５，１６に第４の実施形態を示す。第４の実施形態は、特に第２止着部を背側で固定するのに適した形態である。図１５は、第４の実施形態に係るおむつの展開図の背面図を示す。図１５において、第２止着部は第１〜第３の実施形態に比して幅方向に長く、本体幅方向端部側のみがサイドフラップ部１１，１２に固着されている。また、第２止着部４３，４４の止着手段４３ｘ，４４ｘは、外側面に固着されている。 (Fourth embodiment)
15 and 16 show a fourth embodiment. The fourth embodiment is particularly suitable for fixing the second fastening portion on the back side. FIG. 15: shows the rear view of the expanded view of the diaper which concerns on 4th Embodiment. In FIG. 15, the second fastening part is longer in the width direction than in the first to third embodiments, and only the end part in the body width direction is fixed to the side flap parts 11 and 12. Further, the fastening means 43x, 44x of the second fastening parts 43, 44 are fixed to the outer surface.

本実施形態に係るおむつの着用において、第１止着部の係止までは、第１の実施形態と同様に実施される。第２止着部を腹側係止部に係止する際には、第２止着部のサイドフラップ部への固着部の根元より腹側に折り返すことにより、係止可能である。 In the wearing of the diaper according to the present embodiment, the steps up to the locking of the first fastening portion are performed in the same manner as in the first embodiment. When the second fastening portion is locked to the ventral side locking portion, the second fastening portion can be locked by folding back to the ventral side from the root of the fixing portion to the side flap portion of the second fastening portion.

第２止着部を背側で係止する際において、本実施形態は、図１６及び図１２（ｂ）に示すように、第２止着部の部材同士で係止することが可能である。サイドフラップ部１１，１２を背側に折り返した場合、第２止着部４３，４４の止着手段４３ｘ，４４ｘはいずれも外側面に配されるため、互いに係止することが困難である。しかし、本実施形態においては、第２止着部４３，４４も部材の非固着側の端部に、止着手段４３ｘ，４４ｘよりも幅方向に長い折り代部４３ｙ，４４ｙを有し、当該折り代部４３ｙ，４４ｙを止着手段側に折り返すことにより、止着手段４３ｘ，４４ｘをカバーすることができる。図示例においては、止着手段４３ｘが折り代部４３ｙでカバーされている。一方、止着手段４４ｘは、折り代部４４ｙではカバーされずに、そのまま内側に折り返され、折り代部４３ｙの裏面側に係止している。なお、止着手段４３ｘ，４４ｘ及び折り代部４３ｙ，４４ｙをそれぞれ逆の形態としてもよい。このような構成とすることで、おむつ本体の外側にフックテープ等の止着手段が露出することなく、第２止着部同士を係止することが可能である。 When the second fastening portion is locked on the back side, as shown in FIGS. 16 and 12B, this embodiment can be locked between the members of the second fastening portion. . When the side flap portions 11 and 12 are folded back, the fastening means 43x and 44x of the second fastening portions 43 and 44 are all arranged on the outer surface, so that it is difficult to lock them together. However, in the present embodiment, the second fastening portions 43 and 44 also have folding margins 43y and 44y that are longer in the width direction than the fastening means 43x and 44x at the end of the non-fixed side of the member. The folding means 43x and 44x can be covered by folding the folding margins 43y and 44y toward the fastening means. In the illustrated example, the fastening means 43x is covered with a folding margin 43y. On the other hand, the fastening means 44x is not covered by the folding margin portion 44y, but is folded back as it is and is locked to the back surface side of the folding margin portion 43y. The fastening means 43x and 44x and the folding margins 43y and 44y may be reversed. By setting it as such a structure, it is possible to latch 2nd fastening parts, without fastening means, such as a hook tape, exposing the outer side of a diaper main body.

図示例においては、２つの第２止着部４３，４４を同一の形態とし、いずれの止着部をもう一方の止着部に係止してもよい構成としたが、例えば、第２止着部４４のみ、本体内側面に止着手段４４ｘを設け、かつ折り代部を設けない形態とし、第２止着部間の係止を不可逆的に行う構成としてもよい。 In the illustrated example, the two second fastening portions 43 and 44 have the same configuration, and either fastening portion may be locked to the other fastening portion. Only the attachment part 44 may be configured such that the fastening means 44x is provided on the inner side surface of the main body and the folding margin part is not provided, and the second fastening part is locked irreversibly.
