At the side of the joint portion 31 on the surface of the continuous belt portion 25a, it is disposed along the direction orthogonal to the flow direction, and the ventral side fastener 52 is disposed on the surface side of the continuous diaper body 1a, that is, FIG. It arrange | positions in the position corresponding to the back side surface-shaped fastener 36 in the other end part of the continuous exterior surface sheet 15a shown to a) (fastener arrangement | positioning process). In addition, this fastener arrangement | positioning process is good also as a process before the said joining process. Further, in the fastener disposing step, the continuous diaper main body 1a is formed with a substantially hexagonal continuous leg periphery 8a that is sequentially cut out in the flow direction.

さらに、図6(g)に示すように、ファスナ配設工程を経た連続おむつ本体1aを、背側面状ファスナ36と腹側面状ファスナ52とが互いに対向するように折り畳んで背側面状ファスナ36と腹側面状ファスナ52とを互いに係合させる(折り畳み係合工程)。   Furthermore, as shown in FIG. 6 (g), the continuous diaper body 1a that has undergone the fastener disposing step is folded so that the back side fastener 36 and the ventral side fastener 52 face each other, and the back side fastener 36 and the ventral side surface are folded. The fasteners 52 are engaged with each other (folding engagement step).

そして、図6(h)に示すように、折り畳み係合工程を経た連続おむつ本体1aを、接合部31が流れ方向に略二分される位置にて幅方向にそれぞれ切断し(本体切断工程)、パンツ形状に形成されたおむつ本体1を完成する。   And as shown in FIG.6 (h), the continuous diaper main body 1a which passed through the folding engagement process is each cut | disconnected in the width direction in the position where the junction part 31 is substantially divided into the flow direction (main body cutting process), The diaper main body 1 formed in a pants shape is completed.

次に、上記第1の実施の形態の作用を説明する。   Next, the operation of the first embodiment will be described.

装着者自身が装着する際には、切取り可能線34を切断せずに、背側腰回り部7の両側部にそれぞれ設けた背側面状ファスナ36と腹側腰回り部10の両側部にそれぞれ設けた腹側面状ファスナ52とを係合させるとともに、第1ベルト部面状ファスナ37を腹側腰回り部10の外装内面シート15に係合させることで、おむつ本体1が図4に示す立体パンツ形状となるため、装着者の胴体部が空間部Sに位置するように下着のように着脱することが可能となり、着脱性および肌への密着感が良好になる。   When the wearer wears it, it is provided on both sides of the back side fastener 36 and the ventral side waist part 10 provided on both sides of the back side waist part 7 without cutting the cuttable wire 34, respectively. The diaper body 1 is shown in FIG. 4 by engaging the abdomen side surface fastener 52 and engaging the first belt portion surface fastener 37 with the exterior inner surface sheet 15 of the abdomen waist portion 10. Since it becomes a shape, it becomes possible to attach and detach like an underwear so that a wearer's trunk | drum is located in the space part S, and attachment / detachment and a feeling of close_contact | adherence to skin become favorable.

また、各面状ファスナ36,52の係合を外すとともに、第1ベルト部面状ファスナ37と腹側腰回り部10との係合を外すことで腹側腰回り部10を装着者の前方へと開いても、ベルト部25が装着者の腰回りに固定されているので、例えばおむつ本体1の内部の汚れの有無の確認、あるいは、例えばインナにパッドを使用する場合にはこのインナパッドの交換などを、例えば装着者がその都度ズボンなどを脱ぐことなく容易にできる。   In addition, disengagement of each of the planar fasteners 36 and 52 and disengagement of the first belt portion planar fastener 37 and the abdominal waistline portion 10 allows the abdominal waistline portion 10 to move forward of the wearer. Even if the belt portion 25 is opened, the belt portion 25 is fixed around the wearer's waist. For example, if the inner portion of the diaper body 1 is checked for dirt, or if the inner pad is used, for example, For example, the wearer can easily replace the pants without taking off the pants each time.

さらに、おむつ本体1は、切取り可能線34を切断すると、展開型おむつとして使用できるので、例えばベッドなどから立ち上がることが困難な装着者などに対して介助者がおむつ本体1を着脱する場合などにも容易に適用でき、着脱の操作性も良好となる。   Furthermore, since the diaper main body 1 can be used as an unfolded diaper by cutting the cuttable line 34, for example, when an assistant attaches and detaches the diaper main body 1 to a wearer who is difficult to stand up from a bed or the like. Can be easily applied, and the operability of attachment / detachment is also good.

しかも、切取り可能線34を切断した後には、図5に示すように、各ベルト部面状ファスナ37,38を係合させることで、切取り可能線34を切断する前のベルト部25と同様に空間部Sを形成して立体パンツ形状として使用可能となり、使い勝手が良好である。   Moreover, after the cuttable line 34 is cut, as shown in FIG. 5, the belt portion planar fasteners 37 and 38 are engaged, as in the belt portion 25 before cutting the cutable line 34. The space portion S is formed and can be used as a three-dimensional pants shape, which is easy to use.

すなわち、上記第1の実施の形態の使い捨て吸収性物品は、展開型のおむつでありながら、立体パンツ形状としても使用できるので、立体パンツ形状と展開型とのそれぞれの利点を選択して装着者に応じて適用することができ、使い勝手が良好となる。   That is, since the disposable absorbent article of the first embodiment can be used as a three-dimensional pant shape while being a developed diaper, the wearer can select the advantages of the three-dimensional pant shape and the developed type. It can be applied depending on the situation, and the usability is improved.

また、切取り可能線34からベルト部25を切断すると、各ベルト部面状ファスナ37,38を係合させることでベルト部25の締め付け具合を調整でき、装着者の様々な腰回りのサイズに対応できる。   In addition, when the belt part 25 is cut from the cuttable wire 34, the fastening condition of the belt part 25 can be adjusted by engaging each belt part surface fastener 37, 38, so that the waist size of the wearer can be adjusted. it can.

そして、一旦展開状態としたおむつ本体1は、装着者の腰回りの両側部で対向する背側腰回り部7のベルト部25の表面側と腹側腰回り部10の表面側とで各面状ファスナ36,52により係合するので、順次折り畳むだけで容易に立体パンツ形状に再度形成できる。   The diaper main body 1 once in the unfolded state is formed into a planar shape on the surface side of the belt portion 25 of the back waist portion 7 and the surface side of the abdominal waist portion 10 facing each other on both sides of the waist of the wearer. Since they are engaged by the fasteners 36 and 52, they can be easily formed again into a three-dimensional pant shape by simply folding them in sequence.

また、一般的に、フックファスナは、外装シート6に使用される不織布やループファスナと比較して突起物があり、感触が硬いため、装着者の身体に当たらないようにすることが好ましいが、本実施の形態では、装着時にフックファスナが全て装着者の身体とは反対の外側に向く背側面状ファスナ36と第1ベルト部面状ファスナ37とのそれぞれをフックファスナとすることで、これらファスナ36,37により装着者の身体を誤って傷つけることを確実に防止できる。   In general, the hook fastener has protrusions compared to the nonwoven fabric and loop fastener used for the exterior sheet 6, and since it is hard to touch, it is preferable not to hit the wearer's body, In the present embodiment, the hook fasteners are the hook side fasteners 36 and the first belt surface side fasteners 37 that are all hook fasteners facing the outside opposite to the wearer's body when worn. 36 and 37 can reliably prevent the wearer's body from being injured by mistake.

さらに、ループファスナより硬いフックファスナである各ファスナ36,37を比較的小さく、ループファスナである各面状ファスナ38,52を比較的大きく形成することで、おむつ本体1の硬さを軽減して密着性を向上できる。   Furthermore, the hardness of the diaper main body 1 is reduced by forming the fasteners 36 and 37, which are harder than the loop fasteners, to be relatively small and the surface fasteners 38, 52 being the loop fasteners to be relatively large. Adhesion can be improved.

そして、各面状ファスナ36,37,38,52の幅寸法を狭く、かつ、長手方向を広くすることにより、おむつ本体1の長手方向に分割された背側面状ファスナ36,36間の隙間を少なくできる。   Then, by narrowing the width dimension of each planar fastener 36, 37, 38, 52 and widening the longitudinal direction, a gap between the back side fasteners 36, 36 divided in the longitudinal direction of the diaper body 1 is formed. Less.

また、ベルト部25の幅方向への引っ張り強度を、各腰回り部7,10の幅方向への引っ張り強度よりも小さくすることで、ベルト部25により装着者の腰回りを締め付けすぎてしまうことがないので、装着感が良好になる。   Also, by making the tensile strength in the width direction of the belt portion 25 smaller than the tensile strength in the width direction of the waist portions 7 and 10, the waist portion of the wearer is tightened too much by the belt portion 25. Since there is no, a feeling of wearing becomes good.

さらに、背側腰回り部7にベルト部25を設けることにより、各面状ファスナ36,52を剥がす際に、腹側面状ファスナ52を装着者の背面側から腹面側に向かって剥がすことになるので、装着者の腹面側から背面側へと剥がす場合と比較して、各面状ファスナ36,52の係合を容易に剥がすことができる。   Furthermore, by providing the belt portion 25 on the back waist portion 7, the strip side fasteners 52 are peeled from the back side of the wearer toward the ventral side when the planar fasteners 36, 52 are peeled off. Therefore, compared with the case where it peels from a wearer's abdominal surface side to a back surface side, engagement of each planar fasteners 36 and 52 can be peeled off easily.

また、背側面状ファスナ36をベルト部25のベルト部シート26に配設することにより、おむつ本体1の装着時に各面状ファスナ36,52が装着者の身体の外周側に位置するから、これら面状ファスナ36,52の係合に対して装着時に、せん断方向に力が加わるので、例えば背側面状ファスナ36を背側腰回り部7の外装内面シート15に配設する場合などのように、各面状ファスナ36,52の係合に対して剥離方向に力が加わることがなく、面状ファスナ36,52の係合が外れにくくなる。   Further, by disposing the back side fastener 36 on the belt part seat 26 of the belt part 25, when the diaper body 1 is worn, each of the planar fasteners 36, 52 is located on the outer peripheral side of the wearer's body. Since a force is applied in the shearing direction at the time of mounting with respect to the engagement of the planar fasteners 36 and 52, for example, when the back side surface fastener 36 is disposed on the exterior inner surface sheet 15 of the back waist portion 7, etc. The force in the peeling direction is not applied to the engagement of the planar fasteners 36 and 52, and the engagement of the planar fasteners 36 and 52 is difficult to disengage.

そして、使い捨て吸収性物品の製造に際しては、連続外装シート6aとは別個の連続ベルト部シート26a,27a間にベルト部弾性体28を配設し、表面側の所定位置に、第1ベルト部面状ファスナ37を配設するとともに、裏面側の所定位置に、第2ベルト部面状ファスナ38を配設し、かつ、流れ方向に直交する方向に沿って切取り可能線34を形成した連続ベルト部25aを、おむつ本体形成工程にて形成した連続おむつ本体1aの一端部に沿って配設して、流れ方向と直交する方向に接合部31にて接合するとともに、連続おむつ本体1aの一端部である連続ベルト部25aに背側面状ファスナ36を配設し、かつ、連続おむつ本体1aの他端部に腹側面状ファスナ52を配設することで、各面状ファスナ36,52を連続おむつ本体1aの表面側にて対面係合させることが可能になるので、おむつ本体の両側部を接合、すなわちサイドシールをする一般的な横流れタイプの立体パンツ形状の使い捨て吸収性物品と同様の製造工程に、ベルト部形成工程と、ベルト部加工工程と、接合工程とを加え、サイドシールに代えて各面状ファスナ36,52を係合させることで容易に製造可能となり、製造性を向上できる。   When manufacturing the disposable absorbent article, the belt portion elastic body 28 is disposed between the continuous belt portion sheets 26a and 27a separate from the continuous exterior sheet 6a, and the first belt portion surface is disposed at a predetermined position on the surface side. A continuous belt portion in which a belt-like fastener 37 is provided, a second belt portion surface fastener 38 is provided at a predetermined position on the back surface side, and a cutable line 34 is formed along a direction orthogonal to the flow direction. 25a is disposed along one end of the continuous diaper body 1a formed in the diaper body forming step, and joined at the joint 31 in a direction orthogonal to the flow direction, and at one end of the continuous diaper body 1a. The back side fastener 36 is disposed on a continuous belt portion 25a, and the abdomen side fastener 52 is disposed on the other end of the continuous diaper main body 1a, so that each planar fastener 36, 52 is a continuous diaper main body. Because it is possible to engage face-to-face on the surface side of 1a In the same manufacturing process as a general transverse flow type three-dimensional pants-shaped disposable absorbent article that joins both sides of the diaper body, that is, side seals, a belt part forming process, a belt part processing process, and a joining process In addition, it is possible to easily manufacture by engaging each of the planar fasteners 36 and 52 instead of the side seal, and the productivity can be improved.

しかも、ベルト部形成工程とベルト部加工工程とは、外装シート形成工程およびおむつ本体形成工程と平行して行うことができるので、使い捨て吸収性物品の製造時間が必要以上に増加することもない。   And since a belt part formation process and a belt part processing process can be performed in parallel with an exterior sheet formation process and a diaper main body formation process, the manufacturing time of a disposable absorbent article does not increase more than necessary.

なお、上記第1の実施の形態において、図7に示すように、背側面状ファスナ36を、接合部31の表面側に配設しても、同様の作用効果を奏することが可能である。   In the first embodiment, even if the back side surface fastener 36 is disposed on the surface side of the joint portion 31, as shown in FIG.

また、図8に示すように、ベルト部25は、通気性および軽快性を重視する場合に、おむつ本体1の長手方向の寸法を小さくしてもよい。この場合には、ベルト部25が吸収体本体5と重ならないので、ベルト部25に切欠部35を形成する必要がなく、ベルト部25を矩形状とすることができる。この場合には、例えば背側面状ファスナ36の一部を、背側腰回り部7の外装内面シート15の両側部に配設してもよい。   Moreover, as shown in FIG. 8, the belt part 25 may make the dimension of the longitudinal direction of the diaper main body 1 small, when attaching importance to air permeability and lightness. In this case, since the belt portion 25 does not overlap the absorbent body 5, it is not necessary to form the notch portion 35 in the belt portion 25, and the belt portion 25 can be rectangular. In this case, for example, a part of the back side surface fastener 36 may be disposed on both sides of the exterior inner surface sheet 15 of the back waist portion 7.

次に、第2の実施の形態を図9を参照して説明する。なお、上記第1の実施の形態と同様の構成および作用については、同一符号を付してその説明を省略する。   Next, a second embodiment will be described with reference to FIG. In addition, about the structure and effect | action similar to the said 1st Embodiment, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

この第2の実施の形態は、第1ベルト部面状ファスナ37を、切取り可能線34の近傍のベルト部シート26にて、第1ベルト片32と第2ベルト片33との両方に配設し、第2ベルト部面状ファスナ38を、切取り可能線34の近傍のベルト部シート27にて、第1ベルト片32と第2ベルト片33との両方に配設したものである。   In the second embodiment, the first belt portion planar fastener 37 is disposed on both the first belt piece 32 and the second belt piece 33 on the belt portion sheet 26 in the vicinity of the cut-off line 34. The second belt portion planar fastener 38 is disposed on both the first belt piece 32 and the second belt piece 33 in the belt portion sheet 27 in the vicinity of the cuttable line 34.

すなわち、各面状ファスナ37,38は、それぞれ切取り可能線34を挟んでこの切取り可能線34の両側に離間されてそれぞれ配設されている。   In other words, the planar fasteners 37 and 38 are respectively disposed on both sides of the cuttable line 34 with the cutable line 34 interposed therebetween.

そして、このように構成することで、各面状ファスナ37,38の使用量を低減でき、製造コストを抑制できるとともに、切取り可能線34を切断した後、各面状ファスナ37,38を係合させる場合には、各ベルト片32,33のどちらが上側、あるいは下側となっても各面状ファスナ37,38を係合させることができるので、操作性がより向上する。   With this configuration, the amount of each of the planar fasteners 37 and 38 can be reduced, the manufacturing cost can be reduced, and the cuttable wire 34 is cut, and then the respective planar fasteners 37 and 38 are engaged. In this case, the planar fasteners 37 and 38 can be engaged regardless of which of the belt pieces 32 and 33 is on the upper side or the lower side, so that the operability is further improved.

なお、上記第2の実施の形態において、図10に示すように、切取り可能線34を挟んで両ベルト片32,33に亘って各ベルト部シート26,27に面状ファスナ体53,54をそれぞれ配設し、これら面状ファスナ体53,54が切取り可能線34から切断されることで各面状ファスナ37,38が形成されるように構成することも可能である。この場合には、おむつ本体1の製造に際して、各面状ファスナ体53,54を図6に示す連続おむつ本体1に配設し、これら面状ファスナ体53,54に切取り可能線34を形成することで、各ベルト片32,33にそれぞれ各面状ファスナ37,38を配設する場合と比較して、製造性が向上する。   In the second embodiment, as shown in FIG. 10, the planar fastener bodies 53, 54 are attached to the belt portion sheets 26, 27 across the belt pieces 32, 33 across the cuttable line 34. It is also possible to arrange each of the planar fasteners 53, 54 by cutting the planar fastener bodies 53, 54 from the cuttable line 34, so that the planar fasteners 37, 38 are formed. In this case, when manufacturing the diaper main body 1, the respective planar fastener bodies 53, 54 are disposed on the continuous diaper main body 1 shown in FIG. 6, and a cut-off line 34 is formed in the planar fastener bodies 53, 54. Thus, the productivity is improved as compared with the case where the planar fasteners 37 and 38 are provided on the belt pieces 32 and 33, respectively.

次に、第3の実施の形態を図11を参照して説明する。なお、上記各実施の形態と同様の構成および作用については、同一符号を付してその説明を省略する。   Next, a third embodiment will be described with reference to FIG. In addition, about the structure and effect | action similar to said each embodiment, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

この第3の実施の形態では、腹側腰回り部7の外装内面シート15の幅方向中心域に、おむつ本体1の装着時に対向する部分であるベルト部25の両ベルト片32,33の表面側と係合可能な面状ファスナ55が配設されているものである。   In the third embodiment, the surface of both belt pieces 32 and 33 of the belt portion 25 which is a portion facing when the diaper body 1 is mounted in the central region in the width direction of the exterior inner surface sheet 15 of the abdominal waist portion 7. A planar fastener 55 that can be engaged with the side is disposed.

ここで、面状ファスナ55は、ベルト部シート26が不織布などで形成されている場合には、フックファスナとしてこのベルト部シート26と係合させるようにすればよい。このとき、第1ベルト部面状ファスナ37をループファスナとすることで、面状ファスナ55を第1ベルト部面状ファスナ37とも係合可能とすることができる。この場合には、各面状ファスナ37,38を係合可能とするために、第2ベルト部面状ファスナ38をフックファスナとする。   Here, when the belt portion sheet 26 is formed of a nonwoven fabric or the like, the planar fastener 55 may be engaged with the belt portion sheet 26 as a hook fastener. At this time, by making the first belt portion planar fastener 37 a loop fastener, the planar fastener 55 can be engaged with the first belt portion planar fastener 37. In this case, in order to make each planar fastener 37, 38 engageable, the second belt portion planar fastener 38 is a hook fastener.

なお、第1ベルト部面状ファスナ37は、切取り可能線34からベルト部25を切断した際には第2ベルト部面状ファスナ38と係合されて第2ベルト片33の内側に位置し、面状ファスナ55と対向しなくなるので、面状ファスナ55は、第1ベルト部面状ファスナ37以外の部分でもベルト部25に係合可能となるように形成しておくとよい。   When the belt portion 25 is cut from the cuttable line 34, the first belt portion surface fastener 37 is engaged with the second belt portion surface fastener 38 and is positioned inside the second belt piece 33. Since the planar fastener 55 is not opposed to the planar fastener 55, the planar fastener 55 is preferably formed so that it can be engaged with the belt portion 25 even at portions other than the first belt portion planar fastener 37.

そして、このように構成することで、おむつ本体1の装着時に腹側腰回り部10とベルト部25とが幅方向中心域で係合されるので、腹側腰回り部10とベルト部25とがずれることを確実に防止できる。   And by comprising in this way, since the abdominal side waist part 10 and the belt part 25 are engaged in the center area of the width direction at the time of mounting | wearing of the diaper main body 1, the abdominal side waist part 10 and the belt part 25 are Can be reliably prevented.

なお、上記第3の実施の形態において、ベルト部シート26が不織布などでない場合には、図示しないが、ベルト部シート26にこの面状ファスナ55と係合する面状ファスナを配設すればよい。   In the third embodiment, when the belt portion sheet 26 is not a nonwoven fabric or the like, although not shown, the belt portion sheet 26 may be provided with a planar fastener that engages with the planar fastener 55. .

また、図12に示すように、ベルト部25のベルト部シート26の各ベルト片32,33のそれぞれに、おむつ本体1の装着時に対向する部分である腹側腰回り部10の外装内面シート15と係合可能に面状ファスナ55を配設する構成とすることも可能である。このとき、腹側腰回り部10の外装内面シート15が不織布などで形成されている場合には、面状ファスナ55をフックファスナとするだけで容易に係合可能となる。また、腹側腰回り部10の外装内面シート15が不織布などで形成されていない場合には、腹側腰回り部10にも面状ファスナ55と係合する面状ファスナを配設する。   Further, as shown in FIG. 12, the exterior inner sheet 15 of the ventral waist part 10, which is a part facing each of the belt pieces 32, 33 of the belt part sheet 26 of the belt part 25 when the diaper body 1 is mounted. It is also possible to adopt a configuration in which the planar fastener 55 is disposed so as to be engageable with the other. At this time, when the exterior inner surface sheet 15 of the ventral waist part 10 is formed of a nonwoven fabric or the like, it can be easily engaged only by using the planar fastener 55 as a hook fastener. In addition, when the exterior inner surface sheet 15 of the abdominal waistline portion 10 is not formed of a nonwoven fabric or the like, a planar fastener that engages with the planar fastener 55 is also disposed on the abdominal waistline portion 10.

さらに、上記第1の実施の形態の使い捨て吸収性物品の製造方法は、上記第2および第3の実施の形態でも、それぞれの構成に適宜対応させて適用可能である。   Furthermore, the manufacturing method of the disposable absorbent article according to the first embodiment can be applied to the second and third embodiments as appropriate corresponding to each configuration.
