本発明は、使い捨てオムツに関するものである。  The present invention relates to a disposable diaper.

面ファスナを用いてフィット感を調整できるようにした使い捨てオムツとしては、下記特許文献１に開示されているオムツが知られている。このオムツは、図５のように、いわゆるＴ字型のオムツであり、着用者の縦長部１０１の先端部分（前の胴部）に略全面にわたって設けられた面ファスナ１０２に、横長部１０３の両端に設けられた別の面ファスナ１０４を面接合して、パンツ形状に形成する。
特開２００３−１０２７７７号公報（図１）As a disposable diaper which can adjust a feeling of fitting using a hook and loop fastener, the diaper currently indicated by the followingpatent documents 1 is known. As shown in FIG. 5, this diaper is a so-called T-shaped diaper. Anothersurface fastener 104 provided at both ends is surface-bonded to form a pants shape.
JP2003-102777A (FIG. 1)

かかる使い捨てオムツは、製品出荷時には、そのままの状態では使用できないように折り畳まれている。すなわち、一旦、オムツを展開して身体に当てた後、面ファスナ１０４，１０２をオムツの適切な位置において接合して、オムツを着用しなければならない。かかる着用方法は、自らオムツを着用することができない乳児、重度の病人、いわゆる要介護度が高い老人等にオムツを着せる場合には適切である。  Such disposable diapers are folded so that they cannot be used as they are at the time of product shipment. That is, once the diaper is unfolded and applied to the body, the hook-and-loop fasteners 104 and 102 must be joined at an appropriate position of the diaper and the diaper must be worn. Such a wearing method is appropriate when diapers are worn on infants who cannot wear diapers themselves, severely ill persons, elderly people with high levels of care required, and the like.

一方、差程の介護を必要としない病人や要介護度の低い老人等は自ら着座ないし中腰の姿勢でパンツを着用することができる。しかし、展開されたオムツでは横長部１０３を腰に回しつつ、縦長部１０１を股間に当てがう必要があり、着用することが難しい。むしろ、一般のパンツと同じようにパンツ型のオムツを着用したいという要望がある。したがって、かかる軽度の病人等にとっては、購入時にオムツを展開せずにすぐに着用できるような状態であることが望ましい。  On the other hand, a sick person who does not need the care of the difference, an elderly person with a low degree of care, etc. can wear pants in a sitting or middle waist posture. However, in the developed diaper, it is necessary to apply the verticallylong portion 101 to the crotch while turning the horizontallylong portion 103 to the waist, which is difficult to wear. Rather, there is a desire to wear a pants-type diaper, just like ordinary pants. Therefore, it is desirable for such a mild sick person to be able to wear the diaper immediately without purchasing it at the time of purchase.

ここで、前記図５の面ファスナ１０２，１０４を予め接合して、オムツを予めパンツ形状に形成した上で折り畳んで出荷すれば、オムツを展開せずにすぐに着用することができる。  Here, if the hook-and-loop fasteners 102 and 104 of FIG. 5 are joined in advance and the diaper is formed in a pants shape before being folded and shipped, the diaper can be worn immediately without being unfolded.

しかし、図５の前記オムツを着用した後、フィット感の調整のために接合位置を変更する場合がある。かかる場合に面ファスナ１０２，１０４同士が予め面接合されたオムツでは、面ファスナ１０２，１０４を剥がすのに大きな力を要するので、力の弱い病人や老人にとって、フィット感の調整作業が難しくなる。  However, after wearing the diaper of FIG. 5, the joining position may be changed to adjust the fit. In such a case, a diaper in which the surface fasteners 102 and 104 are surface-bonded in advance requires a large force to peel off thesurface fasteners 102 and 104, so that it is difficult to adjust the fit for a sick person or an elderly person with weak power.

一方、予めパンツ型に形成されたオムツでは、介護者がオムツを病人等に着用させる度にファスナ１０２，１０４を剥がす必要があり面倒である。  On the other hand, in a diaper formed in a pants shape in advance, it is necessary to remove thefasteners 102 and 104 every time a caregiver wears the diaper on a sick person or the like, which is troublesome.

したがって、本発明は、一般のパンツのように着用することができ、かつ、着用後に容易にフィット感を調整することができると共に、オムツとして用いる場合にも用い易い使い捨てオムツを提供することを目的とする。  Accordingly, an object of the present invention is to provide a disposable diaper that can be worn like ordinary pants and can easily adjust the fit after wearing, and is easy to use even when used as a diaper. And

前記目的を達成するために、本発明のある使い捨てオムツは、着用者の胴回りにフィットする胴部と、着用者の股間を覆う股部と、を備えた使い捨てオムツであって、前記胴部は、着用者の後の胴から胴回りに沿って着用者の前の胴まで延びる第１胴部と、少なくとも着用者の前の中央の胴を覆う第２胴部と、を備え、前記第１胴部は、前記第２胴部よりも胴回り方向に長く、前記第１胴部は、胴回り方向の両端部の内表面に、各々、雄面ファスナ（接合要素の一例）を備え、前記第２胴部は、雌面ファスナ（被接合面を形成する部材の一例）と、不織布からなる仮接合面とを外表面に備え、前記仮接合面は着用者の前の胴の略中央に設けられていると共に、少なくとも前記仮接合面の胴回り方向の両側には前記雌面ファスナが配置されており、前記雄面ファスナは前記雌面ファスナ及び前記仮接合面に接合可能であり、前記仮接合面と前記雄面ファスナとの係合力は、前記雌面ファスナと雄面ファスナとの係合力よりも小さく、前記仮接合面に前記雄面ファスナが仮接合されて、パンツ型に折り畳まれている。
本発明においては、雄面ファスナに代えて、接合要素の一例として粘着テープが用いられることができる。この場合、被接合面や仮接合面としては雌面ファスナに代えて平滑な表面を持つ部材が用いられてもよい。In order to achieve the above object, a disposable diaper according to the present invention is a disposable diaper having a torso that fits around a wearer's waist and a crotch that covers the wearer's crotch, and the torso is A first torso extending from the back torso of the wearer to the torso in front of the wearer, and a second torso covering at least the center torso in front of the wearer, the first torso The first body is provided with male surface fasteners (an example of a joining element) on the inner surface of both ends in the waist direction, and the second body is longer than the second body. The portion includes a female surface fastener (an example of a member that forms a surface to be bonded) and a temporary bonding surface made of a non-woven fabric on the outer surface, and the temporary bonding surface is provided at the approximate center of the trunk in front of the wearer The female surface fasteners are disposed at least on both sides of the temporary bonding surface in the waistline direction. The male surface fastener is connectable to the female surface fastener and the temporary bonding surface, and the engagement force between the temporary bonding surface and the male surface fastener is greater than the engagement force between the female surface fastener and the male surface fastener. The male fastener is temporarily joined to the temporary joint surface and is folded into a pants shape.
In the present invention, an adhesive tape can be used as an example of the joining element instead of the male fastener. In this case, a member having a smooth surface may be used as the bonded surface or the temporary bonding surface instead of the female surface fastener.

かかる使い捨てオムツは、予めパンツ型に折り畳まれているので、着用者はオムツを展開することなく、一般のパンツのように仮に着用することができる。雄面ファスナは雌面ファスナに接合されているのではなく、係合力の弱い不織布の仮接合面に接合されているから、前記仮の着用後に、着用者は小さな力で雄面ファスナを仮接合面から剥がした後に、雄面ファスナに雌面ファスナを係合させて雄面ファスナの接合位置を容易に変更できる。つまり、フィット感の調整を容易に行うことができる。したがって、足腰の弱い老人でも介護者の介護なしで自身でオムツを着用することができる。
なお、仮接合面とは別に雌面ファスナが設けられており、当該雌面ファスナに雄面ファスナを接合することにより、大きな係合力を得ることもできる。Since such disposable diapers are folded in a pants shape in advance, the wearer can temporarily wear them like ordinary pants without unfolding the diapers. Since the male fastener is not joined to the female fastener, it is joined to the temporary joining surface of the nonwoven fabric with weak engagement force, so that after the temporary wearing, the wearer temporarily joins the male fastener with a small force. After peeling from the surface, the male surface fastener can be engaged with the male surface fastener to easily change the joining position of the male surface fastener. That is, it is possible to easily adjust the fit. Therefore, even elderly people with weak legs can wear diapers themselves without the caregiver's care.
A female surface fastener is provided separately from the temporary bonding surface, and a large engagement force can be obtained by bonding the male surface fastener to the female surface fastener.

一方、介護者が病人等にオムツを着用させる際には、係合力の弱い不織布から雄面ファスナを小さな力で剥がして、オムツを展開した状態にすることで、通常のオムツとして本オムツを着用させることができる。
本発明において、雌面ファスナは、市販の雌面ファスナを用いることも可能であるが、前記仮接合面を形成する不織布よりも起毛された（毛羽立ちの大きい）不織布を用いることもでき、この場合も本発明の範囲に含まれる。On the other hand, when a caregiver makes a sick person wear a diaper, the diaper is unfolded by peeling off the male fastener from the non-woven fabric with weak engagement force, and the diaper is unfolded. Can be made.
In the present invention, as the female surface fastener, a commercially available female surface fastener can be used, but a non-woven fabric that is raised (larger fluff) than the non-woven fabric forming the temporary joining surface can be used. Are also included within the scope of the present invention.

前記雌面ファスナは、胴回り方向に互いに離間した一対の雌面ファスナからなり、前記一対の雌面ファスナの間において前記仮接合面が露出しているのが好ましい。  The female surface fastener is preferably composed of a pair of female surface fasteners spaced apart from each other in the waistline direction, and the temporary joining surface is exposed between the pair of female surface fasteners.

本発明の好ましい態様においては、前記仮接合面を形成する不織布の外表面に前記雌面ファスナが接着されている。一般に、第２胴部は外表面に不織布を持っているので、前記第２胴部の一部を形成する不織布により仮接合面が形成されていることで製造性の低下を招かない。  In a preferred embodiment of the present invention, the female surface fastener is bonded to the outer surface of the nonwoven fabric forming the temporary bonding surface. Generally, since the second body portion has a non-woven fabric on the outer surface, the temporary joining surface is formed by the non-woven fabric forming a part of the second body portion, so that the productivity is not lowered.

本発明の別の好ましい態様においては、前記仮接合面を形成する不織布は前記第２胴部から胴回り方向の両側に向って延びるフラップを形成すると共に、当該不織布には胴回り方向に伸縮可能な弾性部材が設けられている。
このようにすれば、着用後にフィット感を調整する際にフラップをつまんで第２胴部が胴回り方向に移動しないようにして雄面ファスナの接合位置を調整できるので、フィット感の調整が更に容易になる。また、第２胴部に弾性部材を設けることにより、着用者の前の胴におけるオムツのフィット性が向上する。In another preferable aspect of the present invention, the nonwoven fabric forming the temporary joining surface forms a flap extending from the second body portion toward both sides in the waistline direction, and the nonwoven fabric has elasticity that can expand and contract in the waistline direction. A member is provided.
In this way, when adjusting the fit after wearing, the joint position of the male fastener can be adjusted by pinching the flap so that the second torso does not move in the waistline direction, making it easier to adjust the fit become. Moreover, by providing an elastic member on the second torso, the fit of the diaper on the torso in front of the wearer is improved.

以下、本発明の実施例を図面にしたがって説明する。  Embodiments of the present invention will be described below with reference to the drawings.

第１実施例：
まず、本発明の第１実施例を図１〜図３にしたがって説明する。本実施例は本発明の原理的な実施例であり、いわゆるＴ型の使い捨てオムツの基本的な構造および原理を説明する。
図１（ａ），図１（ｂ）は、本発明の使い捨てオムツの基本的な構造を示す概略斜視図である。図１（ａ）は部分的に展開された状態のオムツを示し、図１（ｂ）は折り畳んだ出荷時の状態のオムツを示す。First embodiment:
First, a first embodiment of the present invention will be described with reference to FIGS. This embodiment is a principle embodiment of the present invention, and the basic structure and principle of a so-called T-type disposable diaper will be described.
Fig.1 (a) and FIG.1 (b) are schematic perspective views which show the basic structure of the disposable diaper of this invention. FIG. 1 (a) shows a diaper in a partially expanded state, and FIG. 1 (b) shows a diaper in a folded state at the time of shipment.

図１（ａ）に示すように、使い捨てオムツは、着用者の胴回りにフィットする胴部１と、着用者の股間を覆う股部２とを備える。前記胴部１は、少なくとも着用者の後の胴を覆う第１胴部１１と、少なくとも着用者の前の胴を覆う第２胴部１２とを備える。前記第１胴部１１は、前記第２胴部１２よりも胴回り方向Ｘに長く形成されている。
第１胴部１１は、着用者の後の胴から胴回り方向Ｘの両側に延びるように形成されている。。第１胴部１１の胴回り方向Ｘの長さは、使用時に着用者の後の胴から胴回りに沿って着用者の前の胴まで届く程度である。一方、第２胴部１２の胴回り方向Ｘの長さは、この例では前記股部２のそれと概ね同じである。As shown to Fig.1 (a), a disposable diaper is provided with the trunk |drum 1 which fits a wearer's waist, and thecrotch part 2 which covers a wearer's crotch. The said trunk |drum 1 is provided with the 1st trunk |drum 11 which covers the trunk | drum after a wearer at least, and the 2nd trunk |drum 12 which covers the trunk | drum before a wearer at least. Thefirst body portion 11 is formed longer in the waistline direction X than thesecond body portion 12.
The 1st trunk |drum 11 is formed so that it may extend to the both sides of the trunk periphery direction X from the trunk | drum of a wearer's back. . The length of thefirst torso 11 in the waistline direction X is such that it reaches the torso in front of the wearer along the torso from the torso behind the wearer during use. On the other hand, the length of thesecond body 12 in the waist direction X is substantially the same as that of thecrotch 2 in this example.

前記第１胴部１１は、胴回り方向Ｘの両端部１５，１５の内表面（肌に対面する側の面）に、各々、雄面ファスナＭ，Ｍを備える。前記第２胴部１２は、胴回り方向Ｘの両端部１７，１７の外表面（肌に対面しない側の面）に、各々、雌面ファスナＦ，Ｆを備える。前記雌面ファスナＦ，Ｆは、前記第２胴部１２を構成する不織布の表面に接着されている。前記第２胴部１２の不織布は、着用者の前の胴の略中央部分（胴回り方向Ｘの略中央部分）の外表面において露出した仮接合面３を形成する。前記雌面ファスナＦ，Ｆは、胴回り方向Ｘに互いに離間して配置されており、仮接合面３は両雌面ファスナＦ，Ｆに挟まれるように配置されている。  Thefirst body portion 11 includes male surface fasteners M and M on inner surfaces (surfaces facing the skin) of bothend portions 15 and 15 in the waistline direction X, respectively. The said 2nd trunk |drum 12 is equipped with the female surface fasteners F and F on the outer surface (surface of the side which does not face skin) of the bothends 17 and 17 of the trunk periphery direction X, respectively. The female surface fasteners F, F are bonded to the surface of the nonwoven fabric constituting thesecond body 12. The nonwoven fabric of thesecond body portion 12 forms the temporary bonding surface 3 exposed on the outer surface of the substantially central portion (substantially central portion in the waistline direction X) of the torso in front of the wearer. The female surface fasteners F and F are disposed so as to be separated from each other in the waistline direction X, and the temporary joining surface 3 is disposed so as to be sandwiched between the female surface fasteners F and F.

前記第２胴部１２の雄面ファスナＭ，Ｍは、前記雌面ファスナＦ，Ｆにも不織布からなる前記仮接合面３にも接合可能である。前記雄面ファスナＭ，Ｍと仮接合面３とを接合した場合の係合力は、雄面ファスナＭ，Ｍと雌面ファスナＦ，Ｆとを接合した場合の係合力よりも小さい。  The male surface fasteners M, M of thesecond body portion 12 can be bonded to the female surface fasteners F, F and the temporary bonding surface 3 made of a nonwoven fabric. The engaging force when the male fasteners M, M and the temporary joining surface 3 are joined is smaller than the engaging force when the male fasteners M, M and the female fasteners F, F are joined.

図１（ｂ）に示すように、出荷時の状態では、前記第１胴部１１が折り畳まれて、第１胴部１１の両端部１５，１５が第２胴部１２の外表面に重ねられる。この際、前記雄面ファスナＭ，Ｍの少なくとも一部が、前記仮接合面３に接合される。この雄面ファスナＭ，Ｍおよび仮接合面３の接合は、係合力の弱い仮接合の状態である。  As shown in FIG. 1 (b), in the state at the time of shipment, thefirst body part 11 is folded and bothend parts 15, 15 of thefirst body part 11 are overlapped on the outer surface of thesecond body part 12. . At this time, at least a part of the male fasteners M, M are joined to the temporary joining surface 3. The joining of the male fasteners M, M and the temporary joining surface 3 is a temporary joining state with a weak engagement force.

このようにして、パンツ型に折り畳まれた使い捨てオムツが形成される。パンツ型に形成されているので、そのままパンツのように着用することができる。また、前記のように、雄面ファスナＭ，Ｍが仮接合面３に仮接合された状態であるから、一旦、着用した後、雄面ファスナＭ，Ｍを仮接合面３から小さな力で容易に剥がすことができ、雄面ファスナＭ，Ｍを第２胴部１２の雌面ファスナＦ，Ｆに接合して、着用者に合わせたフィット感が得られる。この際、雄面ファスナＭ，Ｍは雌面ファスナＦ，Ｆに接合されるので、より強力に接合される。
勿論、Ｔ型に展開して、通常のオムツとして横たわっている病人等に着用させることもできる。In this manner, a disposable diaper folded into a pants shape is formed. Since it is formed in a pants shape, it can be worn as it is. Moreover, since the male fasteners M and M are temporarily joined to the temporary joining surface 3 as described above, the male fasteners M and M can be easily attached to the temporary joining surface 3 with a small force after wearing. The male surface fasteners M, M can be joined to the female surface fasteners F, F of thesecond body 12 to provide a fit that fits the wearer. At this time, the male fasteners M, M are joined to the female fasteners F, F, so that they are joined more strongly.
Of course, it can be developed into a T shape and worn by a sick person or the like lying as a normal diaper.

なお、前記図１（ａ），図１（ｂ）では、雄面ファスナＭ，Ｍは仮接合面３にちょうど嵌り込むような大きさに形成されているが、必ずしもそのように形成する必要はない。例えば、図２（ａ）のように、より小さな雄面ファスナＭ，Ｍを用いて、雄面ファスナＭ，Ｍが仮接合面３の一部にのみ接合するようにしてもよい。また、図２（ｂ）のように、より大きな雄面ファスナＭ，Ｍを用いて、雄面ファスナＭ，Ｍが仮接合面３の少なくとも一部および雌面ファスナＦ，Ｆの一部に接合するようにしてもよい。なお、図２（ａ），図２（ｂ）の平面図では、雄面ファスナＭの設けられた部分を明瞭にするために、当該部分に網かけを施している。  In FIGS. 1 (a) and 1 (b), the male fasteners M and M are sized so as to fit into the temporary joining surface 3. However, it is not always necessary to form such male fasteners. Absent. For example, as shown in FIG. 2A, the male fasteners M, M may be joined only to a part of the temporary joining surface 3 by using smaller male fasteners M, M. Further, as shown in FIG. 2B, the male fasteners M, M are joined to at least a part of the temporary joining surface 3 and a part of the female fasteners F, F by using larger male fasteners M, M. You may make it do. In the plan views of FIGS. 2A and 2B, the portion provided with the male fastener M is shaded in order to clarify the portion.

また、前記図１（ａ），図１（ｂ）では、第２胴部１２の外表面を形成する不織布に一対の雌面ファスナＦ，Ｆを互いに離間して配置、接着することで、その間に仮接合面３を形成したが、必ずしもかかる構造を採用する必要はない。例えば、図３（ａ）のように、中央に孔４１を有する１つの雌面ファスナＦを前記不織布に接着することで、雌面ファスナＦに囲まれた仮接合面３を形成できる。また、図３（ｂ）のように、第２胴部１２を形成する不織布４３とは別の不織布４４を雌面ファスナＦの上に接着することで、仮接合面３を形成することもできる。この場合、図３（ｃ）のように、第２胴部１２を形成する不織布４３の上に、胴回り方向Ｘに沿って第２胴部１２を横断する１つの雌面ファスナＦを接着し、さらに該雌面ファスナＦの上に別の不織布４４を接着する。しかし、かかる図３（ａ），（ｂ）の構造よりも図１（ａ）の構造の方が製造が容易である。  Further, in FIGS. 1A and 1B, a pair of female surface fasteners F and F are disposed and bonded to the nonwoven fabric forming the outer surface of thesecond body 12 while being separated from each other. Although the temporary joining surface 3 is formed in the above, such a structure is not necessarily adopted. For example, as shown in FIG. 3A, the temporary joining surface 3 surrounded by the female surface fastener F can be formed by bonding one female surface fastener F having ahole 41 at the center to the nonwoven fabric. Further, as shown in FIG. 3B, the temporary joining surface 3 can be formed by adhering anon-woven fabric 44 different from thenon-woven fabric 43 forming thesecond body 12 on the female surface fastener F. . In this case, as shown in FIG. 3C, one female surface fastener F that crosses thesecond body portion 12 along the waistline direction X is bonded onto thenonwoven fabric 43 that forms thesecond body portion 12. Further, anothernon-woven fabric 44 is bonded onto the female surface fastener F. However, the structure of FIG. 1 (a) is easier to manufacture than the structure of FIGS. 3 (a) and 3 (b).

第２胴部１２における前記アウター材９２の外表面つまり不織布９２の外表面には、一対の雌面ファスナＦ，Ｆが接着されている。この一対の雌面ファスナＦ，Ｆは、胴回り方向Ｘに互いに離間して設けられていることで、両雌面ファスナＦ，Ｆの間に不織布が露出した仮接合面３が形成される。  A pair of female surface fasteners F and F are bonded to the outer surface of theouter member 92 in thesecond body 12, that is, the outer surface of thenonwoven fabric 92. The pair of female surface fasteners F, F are provided to be separated from each other in the waistline direction X, thereby forming a temporary bonding surface 3 in which the nonwoven fabric is exposed between the female surface fasteners F, F.

なお、図４（ａ）に示すように、第２胴部１２における前記アウター材９２の前記端部９３のうち、仮接合面３に対応する部分には弾性部材７１が図示されていないが、当該部分にも弾性部材７１を設けてもよいし、あるいは、弾性部材７１を短く切断して前記仮接合面３に対応する部分に収縮力が発揮されないようにしてもよい。  As shown in FIG. 4A, theelastic member 71 is not shown in the portion corresponding to the temporary joining surface 3 in theend portion 93 of theouter material 92 in thesecond body portion 12. Theelastic member 71 may be provided also in the part, or theelastic member 71 may be cut short so that the contraction force is not exerted on the part corresponding to the temporary joining surface 3.

また、第２胴部１２における前記アウター材９２は、前記雌面ファスナＦの胴回り方向Ｘの両側に向って延びて、フラップ９９を形成している。このフラップ９９をつまんで第２胴部を固定しながら、面ファスナＦ，Ｍの接合位置を調整できるので、容易にフィット感の調整が可能になる。  Further, theouter material 92 in thesecond body portion 12 extends toward both sides of the female surface fastener F in the waist direction X to form aflap 99. Since the joining position of the hook-and-loop fasteners F and M can be adjusted while pinching theflap 99 and fixing the second body portion, it is possible to easily adjust the fit.

本オムツは、フラップ９９を内側に折り畳み、更に、股部２を折り畳んだ後、第１胴部１１の両端部１５，１５を第２胴部１２の外表面側に重ねて、雄面ファスナＭ，Ｍを仮接合部３に仮接合することで、前記第１実施例と同様にパンツ型に折り畳まれたオムツとなる。  In this diaper, after folding theflap 99 inward and further folding thecrotch portion 2, the bothend portions 15, 15 of thefirst body portion 11 are overlapped on the outer surface side of thesecond body portion 12. , M are provisionally joined to the provisional joining portion 3 so that the diaper is folded into a pants shape in the same manner as in the first embodiment.

ところで、図４のようなオムツでは、雌面ファスナＦ，Ｆ間に仮接合面３を設けずに、雄面ファスナＭをフラップ９９の外表面に接合することも可能である。しかし、こうすると、出荷時のパンツ形状に畳んだ状態において嵩張る。  In the diaper as shown in FIG. 4, the male fastener M can be joined to the outer surface of theflap 99 without providing the temporary joining surface 3 between the female fasteners F and F. However, if it carries out like this, it will be bulky in the state folded into the pants shape at the time of shipment.

ところで、オムツの着用時に雄面ファスナＭ，Ｍを中央の仮接合面３に接合したままの状態で用いられる場合は極めて少ない。したがって、中央には仮接合面３が設けられており、本来の雌面ファスナＦ，Ｆが設けられていないが、何ら支障がない。  By the way, there are very few cases where the male fasteners M, M are used while being joined to the central temporary joining surface 3 when the diaper is worn. Therefore, although the temporary joining surface 3 is provided in the center and the original female surface fasteners F and F are not provided, there is no problem.

なお、前記弾性部材７１，７２，７３としては糸ゴム、平ゴム、網目ゴム、弾性フィルムまたは熱可塑性弾性部材を含む材料を採用してもよい。  Theelastic members 71, 72, 73 may be made of a material including thread rubber, flat rubber, mesh rubber, an elastic film, or a thermoplastic elastic member.

以上のとおり、図面を参照しながら好適な実施形態を説明したが、当業者であれば、本明細書を見て、自明な範囲で種々の変更および修正を容易に想定するであろう。
たとえば、不織布のアウター材を第１および第２胴部にのみ設けて、股部には設けないようにしてもよい。
また、第１胴部のうちコア部が配置された部分に弾性部材を設けるようにしてもよい。
したがって、そのような変更および修正は、請求の範囲から定まる本発明の範囲内のものと解釈される。As described above, the preferred embodiments have been described with reference to the drawings. However, those skilled in the art will readily understand various changes and modifications within the obvious scope by looking at the present specification.
For example, a non-woven outer material may be provided only on the first and second body parts and not on the crotch part.
Moreover, you may make it provide an elastic member in the part by which the core part is arrange | positioned among 1st trunk | drums.
Accordingly, such changes and modifications are to be construed as within the scope of the present invention as defined by the claims.
