The flap sheet 5 has a substantially trapezoidal shape in which the long side is directed inward in the width direction and the diaper longitudinal end edge and one side of the flap sheet 5 are in a straight line. A pair of left and right is arranged at each longitudinal end.

FIG. 2 is an enlarged sectional view taken along line II-II in FIG. The fastening tape 4 in the present embodiment is disposed on the side edge in the width direction on the non-skin contact surface side of the back side flap Sr, and in the unfolded state, the first in order from the side flap side edge. The region 41 and the second region 42 are partitioned by a partition line (boundary line) 4w. In the figure, the shape indicated by a two-dot chain line is the fastening tape 4 in a developed state. The fastening tape 4 in a state before deployment (when not in use) is joined to the back side flap Sr so that the first portion 41 and the joint t to which the first portion 41 is attached face each other. The part is not joined to the back side flap (side edge) Sr. The joint part side edge in the width direction of the first part 41 joined by the joint part t is set at the same position as the edge Sa in the width direction of the back side flap Sr. Further, in the folding structure of the fastening tape 4, the second portion 42 is folded back to the opposite side of the side edge portion at a partition line (boundary line) 4 w so that the second portion 42 faces the first portion 41, and a folded portion 4 b is formed. Yes.
In this embodiment, it has the structure folded so that the side edge Sr, the 1st site | part 41, and the 2nd site | part 42 may overlap before seeing in the thickness direction. Furthermore, the fastening tape 4 is folded back at the boundary between the fastening tape 4 and the side edge portion Sr, and the second portion 42 is the first portion at the boundary 4w between the first portion 41 and the second portion 42 of the fastening tape 4. 41 is folded back so as to be located on the side opposite to the side edge portion Sr. As described above, in this embodiment, the side flap (side edge) Sr, the first portion 41 of the fastening tape, and the second portion 42 are Z-folded in this order. It may be folded into an e-shape so as to be sandwiched between the first portion 41 and the side flap Sr (however, the folded portion of the fastening tape is not included in a member constituting the side edge portion). At this time, it is preferable that the second portion 42 and the side flap Sr are temporarily joined by a hook material 43 described later.

  In the present embodiment, a hook member 43 is disposed on the skin contact surface side of the second portion 42. The second portion 42 is detachably provisionally joined to the non-skin contact surface side of the first portion 41 by the hook material 43, and the fastening tape 4 in the present embodiment is substantially folded in the cross section in the unused state. It is made the shape of The hook material 43 includes a hook 43a and a base material 43b on which the hook 43a is disposed. As the hook material 43, a male material of a mechanical fastener that is generally used can be used. The bonding method between the hook member 43 and the second portion 42, and the back side flap Sr and the first portion 41 is not particularly limited, and the hook member 43 and the second portion 42 can be bonded by an adhesive used for a normal sheet material of this type. In the present embodiment, the non-joint side edge (free edge) 4i in the width direction of the fastening tape 4 is not folded and does not exceed the edge Sa in the width direction of the back side flap Sr. Has been.

In the disposable diaper 10, side sheets 8 extending in the longitudinal direction along both widthwise side portions of the absorbent body 3 are disposed on the upper surface (skin contact surface side) of the top sheet 1 (FIG. 6 shows an embodiment). The diaper according to FIG. 2 is common to the first embodiment in a cross section crossing the left and right fastening tapes 4, and is referred to here. The side sheet 8 is made of a non-woven fabric provided with a thread-like or thin string-like elastic member (not shown) forming a pair of erecting leak-proof cuffs arranged on the inner side edge 8a in the width direction. The left and right side sheets 8 are bonded and fixed on the top sheet 1 outside the adhesive base line k indicated by a one-dot chain line outside the side edge of the absorber 3 in the figure. On the contrary, the side sheet 8 is not fixed to the top sheet 1 at the part inside the adhesive base line k, and stands up to form a leak-proof cuff 8 ′. That is, the width direction inner edge 8a side of the leak-proof cuff is configured to stand up three-dimensionally along the diaper longitudinal direction by the gather forming action of the leg elastic member in the diaper wearing state. This three-dimensionally erected leak-proof cuff 8 'is firmly in contact with the skin, effectively preventing excretion from moving to the outside and effectively preventing side leakage.
Although the configuration of the diaper according to the present embodiment as described above has been described, the processing or manufacturing procedure of the diaper including the fastening tape according to the present embodiment is not limited and understood by the expression and order.

  Here, the embodiment at the time of wearing of the disposable diaper 10 of this embodiment is demonstrated in more detail based on FIG. 3, 4, and 5 are perspective views showing a state in which the disposable diaper of the present invention is to be worn by an infant from the front of the body. In the figure, it is assumed that an infant wearing a diaper is in a supine position, and a hand 70 is a mother's hand that causes the infant to wear a diaper. Moreover, the shape at the time of wearing of the disposable diaper 10 is shown schematically and does not necessarily have the same shape as illustrated in the implementation of the present invention.

3, 4 and 5 show the process of pulling out the fastening tape 4 in the diaper 10 of this embodiment in that order. FIG. 3 shows a state in which a baby diaper 71 lying on its back is provided with a diaper back side R on the buttocks side of the baby, a crotch C along the crotch of the baby, and a diaper belly side F applied to the lower abdomen. It is. To attach the diaper, it is necessary to pull out the fastening tape 4 attached to the back side flap Sr and engage it with a landing zone (not shown) on the non-skin contact surface of the abdominal side F. First, the fastening tape Work to draw 4 occurs.
By the way, in the fastening tape without a general folding structure (patent document 2), the fastening tape joined to the skin contact surface side is temporarily joined to the side flap by a hook material, and the free end of the fastening tape is visually observed. The operation of confirming and grasping is performed. Usually, since this type of diaper is folded and packed in a compact state, the side flaps and the fastening tape are also pressed, and there are not many steps between them. Therefore, there was a situation where it was difficult to find the free end in a dark place where there was no “crawl” of the fingertip when pulling out the fastening tape.

On the other hand, the fastening tape 4 in the present embodiment is attached so that the first portion 41 arranged on the non-skin contact surface side and the side flap (side edge portion) Sr face each other, and are joined at the joining portion t. Has been. On the other hand, the first part 41 is not joined to the dorsal side flap Sr at a part other than the joint part t and is in a separated state, and the folded part so that the second part faces the first part. 4b is folded back on the opposite side of the side edge. By adopting this structure, for example, even when working by hand-hunting in the dark, as shown in FIG. 3, a finger is inserted from the outside in the width direction to the non-skin contact surface side of the back side flap Sr portion to explore a little. Thereby, the folding part 4b spaced apart from the back side flap Sr of the fastening tape 4 can be found easily. Then, if the finger is slid from the inner side to the outer side (in the direction of the arrow m) while pressing the folding part 4b, the fastening tape 4 and the back side flap Sr are folded into a U-shape. The fingertip enters the separation portion p ₁ (see FIG. 2), and the fastening tape 4 gradually lifts away from the non-skin contact surface. Further, the folding portion 4b of the fastening tape 4 is rotated in a fan shape with the joint portion t as a fulcrum, and is moved to a position beyond the edge Sa in the width direction of the back side flap Sr (see FIG. 4). Along with the transition, a joint-side folded portion 4c is newly formed at the inner edge in the width direction of the joint t, and the first drawing state (FIG. 4) of the fastening tape is obtained.

Next, the first part 41 and the second part 42 that are temporarily joined by the hook member 43 are peeled and developed to be in a second pulled-out state (see FIG. 5). At this time, gaps p _{2 to} p ₄ due to the thickness of the hook material 43 are formed between the first part 41 and the second part 42 temporarily joined by the hook material 43. By inserting the tip of a thumb or the like without changing the position of the hand in this portion, the temporary engagement can be easily peeled by a series of operations. At this time, even if narrower p ₂ ~p ₄ is pushed, without difficulty is already fastening tape is found, can be developed here. Thereafter, as shown in FIG. 5, the vicinity of the free edge 4 i of the fastening tape is grasped with fingers, and the hook member 43 is attached to a landing tape or the like (not shown) on the abdominal side F to be worn by the infant. be able to. The disposable diaper 10 of the present embodiment can detect and attach the fastening tape 4 by a series of operations by the above-described simple operation, and can easily change the diaper only by touch without relying on vision.

  FIG. 6 is a plan view schematically showing the arrangement position of the fastening tape 4 in the disposable diaper 20 as another embodiment (Embodiment 2) according to the present invention and shown from the skin contact surface side, and the elastic member and the like are not shown. (B) is an enlarged view of the T region in (a), and (c) is a cross-sectional view of the position where the left and right fastening tapes are connected. In the disposable diaper 20 of the present embodiment, a pair of fastening tapes 4 are disposed on the abdominal side flap Sf and the back side flap Sr, respectively. The dimensions and the like of the four fastening tapes 4 are the same as in the first embodiment, and the configuration of the diaper other than the fastening tape is also the same. In addition, the illustrated fastening tape is shown in a pulled-out state.

  In this embodiment, the fastening tape 4 is attached to the abdominal side flap Sf and the back side flap Sr, respectively, and various wearing states are possible. Moreover, the fastening tape 4 of this invention is set to the non-skin contact surface side, and the fastening tape 4 does not contact | abut a wearer's skin in any wearing state. Various mounting states described above will be described below with reference to FIG.

  FIG. 7: is a cross-sectional schematic diagram which showed the cross section in the position of a fastening tape in the state which worn the disposable diaper of this embodiment, and was seen from the head direction. The top sheet 1, the back sheet 2, the absorber 3, the flap sheet 5, and the side sheet are shown as a diaper body 10A by a solid line, and only this and the fastening tape 4 are shown. Further, the cross-sectional shape 73 of the body is a modeled external body portion, and the spine 72 is shown to explain the position of the body. Moreover, about the shape at the time of mounting | wearing of the disposable diaper 10, it does not necessarily need to become the same shape as what was illustrated in implementation of this invention. In the figure, the lower side is the ventral side of the body, and the upper side is the dorsal side of the body.

  When diapers are worn by babies and infants, they may hate to change diapers and swing their bodies from side to side or rampage. In such a case, it is difficult to obtain a correct wearing state, and the diaper that has been forcibly worn is worn in a displaced state, and there are cases where the fastening tape is detached during horizontal use or during use. There are also infants who are interested in the fastening tape and who remove the fastening tape themselves. In such a case, it is preferable to set the fastening tape within the reach of the infant.

According to the diaper of the second embodiment, the fastening tape that is not used in any manner described below is used on the non-skin surface side of the diaper. The free edge 4i does not protrude from the edge Sa in the width direction of the back side flap Sr. Therefore, compared with the general thing in which the fastening tape is arrange | positioned inside a diaper in the unused state, there is no possibility that the skin of an infant may be injured without the fastening tape or its edge part contacting a skin.
The wearing form (i) uses only the fastening tape provided on the back side flap Sr, and does not use the fastening tape provided on the ventral side flap Sf. This wearing form is a wearing form of a general deployment type diaper, and is suitable for changing diapers in a state where an infant is on its back. The wearing form (ii) uses only the fastening tape disposed on the ventral side flap Sf, and does not use the fastening tape disposed on the dorsal side flap Sr. By doing in this way, the fastening tape 4 arrange | positioned on the back side seeing from the infant is hard to reach from the infant who wears, and there exists an effect with respect to the infant who removes the fastening tape itself mentioned above. The wearing form (iii) (iv) uses either the left or right side of the fastening tape disposed on the abdominal side flap Sf, and the fastening tape disposed on the back side side flap Sr is also only on the left or right side. use.
By adopting such a configuration, the right and left fastening tapes 4 disposed on the dorsal and ventral side flaps are selectively used in accordance with the movement of the infant moving when changing the diaper. Is possible. For example, an infant may move during the first change of diapers on his / her back and become prone on the way. However, the disposable diaper 20 of this embodiment can select the fastening tape 4 used for engagement according to the movement. In addition, the fastening tape 4 can be easily found, pulled out, and worn by a series of operations due to the above-described preferred pulling-out property of the fastening tape 4 in the present invention.

Although the dimension and arrangement | positioning position of the fastening tape 4 in this embodiment are not specifically limited, Considering the favorable convenience mentioned above as a disposable diaper for infants, length d ₁ in the width direction of the 1st site | part 41 in the fastening tape 4 10-50 mm is preferable (refer FIG. 2), and 20-30 mm is still more preferable. The length _{d 2} is 20~60mm in the widthwise direction of the second portion 42 is preferably in the fastening tape 4, more preferably 30 to 40 mm. The length d ₃ in the width direction of the joint t is preferably 2 to 10 mm, and more preferably 2 to 5 mm. The length d ₄ (see FIG. 6) in the longitudinal direction of the fastening tape 4 is preferably 20 to 60 mm, and 30 to 30 mm. 40 mm is more preferable. Further, the ratio of the lengths (d ₁ / d ₂ ) in the width direction between the first part 41 and the second part 42 is preferably 0.5, and more preferably 2.

  FIG. 8 is an enlarged cross-sectional view schematically showing Modification 1 of the shape of the fastening tape of the present invention. The position of the cross section is the same as the line II-II in FIG. In the fastening tape 4 of this modification, the non-joint side edge (free edge) 4i in the width direction is longer in the width direction than the edge Sa in the width direction of the back side flap Sr. By doing in this way, it can use easily, without searching a fastening tape.

  FIG. 9 is an enlarged cross-sectional view schematically showing Modification Example 2 of the form of joining to the side flap in the fastening tape of the present invention. The position of the cross section is the same as the line II-II in FIG. The fastening tape 4 of this modification is interposed and joined to the top sheet 1 and the back sheet 2. By doing in this way, the joining force of the junction part t becomes strong, and it does not peel off or drown.

FIG. 10: is an expansion perspective view which shows typically the modification 3, 4, 5 of the arrangement | positioning form to the side flap in the fastening tape of this invention from the diaper non-skin surface side. The side flaps shown in the figure may be either on the back side or on the ventral side.
In the modification 3 shown to (a), the fastening tape 4 is arrange | positioned in the position which deviated to the longitudinal direction outer end edge Sb of the side flap. By doing in this way, it is possible to give a margin around the leg of the diaper, and conversely, there is a firm fit around the waist, and the slippage around the waist is reduced.
In the modified example 4 shown in (b), the fastening tape 4 is disposed at a position deviated to the longitudinal inner edge Sc of the side flap. By doing this, it is possible to have a margin around the waist of the diaper, and conversely, there is a firm fit around the foot, and side leakage of excrement due to slipping around the foot is reduced. .
In the modified example 5 shown in (c), the length in the longitudinal direction of the width direction edge Sa of the side flap is the same as the length in the longitudinal direction of the fastening tape 4. By enlarging the fastening tape in this way, it is easy to grasp and the operation of unfolding the fastening tape is further simplified.

  The fastening tape 4 of the present invention is not limited to the above-described embodiment and modifications, and is preferably determined as appropriate according to the use situation and needs. For example, the first part 41 and the second part 42 may be different members (first member, second member), and in that case, the first part 41 may be an elastic member or the first part 41. It is also preferable that a string-like or thread-like rubber is arranged in the width direction to impart stretchability. By doing in this way, a fastening tape has a stretching property, and the disposable diaper 10 clamp | tightens a wearer's waist appropriately, and shows favorable fitting property. Moreover, since the same effect is acquired even if it uses the elastic member for the flap sheet 5 which makes the side flap to which the fastening tape 4 is attached, it is preferable. In order to further facilitate the discovery of the fastening tape 4 in the dark, it is also preferable to change the color of the entire fastening tape 4 or the non-joint side edge 4i side to a side flap. In this case, it is more effective to use a fluorescent color such as a green tone as a color to be used. Furthermore, it is also preferable to cut the shape of the non-joining part side edge 4i in the width direction of the fastening tape 4 into a corrugated shape constituted by a curve or the like. By using such a shape, it becomes easy to find by tactile sensation of fingers during work by groping in the dark. Furthermore, it is also preferable that the bending rigidity of the fastening tape 4 is higher than that of the side flap. In this way, not only the above-described discovery in the dark is easy, but also the ease of gripping and the ease of work with high rigidity are improved.

  Examples of the stretch sheet when the flap sheet 5 forming the side flap described above has stretch properties include stretch fabrics. For example, the same or different, substantially inelastic, on both sides of the elastic fiber layer. Some are laminated with an inelastic fiber layer. At this time, it is preferable that the elastic fiber layer and the non-elastic fiber layer are bonded to the entire surface by thermal fusion of the fiber intersections in a state where the constituent fibers of the elastic fiber layer maintain the fiber form. In this embodiment, at the interface between the elastic fiber layer and the non-elastic fiber layer and in the vicinity thereof, the intersection of the constituent fiber of the elastic fiber layer and the constituent fiber of the non-elastic fiber layer is heat-sealed. Therefore, it is preferable that the entire surface is uniformly bonded. Further, in at least one of the two inelastic fiber layers, a part of the constituent fibers enter the elastic fiber layer, and / or a part of the constituent fibers of the elastic fiber layer is at least one inelastic. It is preferable to be in a state of entering the fiber layer.

  As the constituent fiber of the elastic fiber layer, for example, a fiber made from a thermoplastic elastomer, rubber or the like can be used. The elastic fiber layer is an aggregate of fibers having elasticity, but inelastic fibers may be included as long as the elastic elasticity is not impaired. The inelastic fiber layer has extensibility but is substantially inelastic. The stretchability here refers to the case where the constituent fibers themselves are stretched, and even if the constituent fibers themselves are not stretched, the two fibers that have been heat-sealed at the intersection of the fibers are separated from each other, or the fibers are thermally fused. Any of the cases in which the three-dimensional structure formed by a plurality of fibers is structurally changed by wearing or the constituent fibers are torn, and the entire fiber layer is elongated. Examples of the fibers constituting the inelastic fiber layer include fibers made of polyethylene (PE), polypropylene (PP), polyester (PET or PBT), polyamide, and the like. Further, core-sheath type or side-by-side composite fibers, split fibers, irregularly shaped cross-section fibers, crimped fibers, heat-shrinkable fibers, and the like can also be used.

  The stretchable nonwoven fabric has stretchability in at least one of the in-plane directions, but may have stretchability in all in-plane directions. In that case, it is not hindered that the degree of elasticity varies depending on the direction. Regarding the direction of expansion and contraction, the degree of elasticity is preferably 10 to 500 cN / 25 mm, more preferably 20 to 100 cN / 25 mm, at 50% elongation. Further, the residual strain when contracted from the 50% stretched state is preferably 15% or less, and more preferably 10% or less.

  In the said embodiment, although the position where the fastening tape 4 is joined to a side flap is a non-skin contact surface side, you may arrange | position to the skin contact surface side without being limited to it. Moreover, the arrangement | positioning position of the hook material 43 in the fastening tape 4 may be the 1st site | part 41 or the 2nd site | part 42, and it is preferable to change suitably according to the arrangement | positioning form to the side flap of said fastening tape 4. FIG. Note that it is also preferable that the above-described modifications are combined. For example, Modification 1 in FIG. 8 and Modification 3 in FIG. 10A are combined, and the non-joint side edge 4i in the width direction of the fastening tape 4 is more than the edge Sa in the width direction of the back side flap Sr. Also, the fastening tape 4 may be long in the width direction and unevenly positioned on the outer side edge Sb in the longitudinal direction of the side flap, or may be various other combinations.

  The hook material 43 of the fastening tape used in the present invention may be a female material. In that case, for example, a pair of male mechanical fasteners may be provided as a landing tape (not shown) on the non-skin contact surface side of the stomach side F of the disposable diaper. The landing tape can be attached to the disposable diaper by fastening the fastening tape, but the non-skin contact surface side of the disposable diaper is attached to the male hook material 43a. Landing tape is not always necessary if it is formed from a possible sheet. Moreover, the fastening tape of this invention is not limited to the said embodiment, According to the performance and form requested | required, it can select suitably using the advantage of each embodiment.

  As a forming material of the fastening tape 4, various tape materials such as a nonwoven fabric or a synthetic resin film used in a normal disposable diaper can be used.
