<Size adjustment means>
4 and 5, the size adjusting means 12 includes a fastening tape 50 and a cover member 51 that covers the whole. The fastening tape 50 is formed of a known fiber nonwoven fabric, for example, a spunbond fiber nonwoven fabric having a mass of about 20 to 100 g / m ² , preferably about 40 to 80 g / m ² . The fastening tape 50 has an inner surface 53 facing the outer surface of the diaper 10 and an outer surface 54 opposite to the inner surface 53, a length direction and a width direction, and inner and outer end edges 50 a, 50 b facing each other in the length direction and the trunk circumference Both side edges 50c extending in the direction, a proximal part 55 fixed via side seams 22 at both side edges of the front waist region 15, and a distal part located on the opposite side of the proximal part 55 in the longitudinal direction 56 and an intermediate portion 57 located between the proximal portion 55 and the distal portion 56. The distal portion 56 has a rectangular fastening region 60 located on the inner surface 53 thereof, and a gripping portion 61 extending from the fastening region 60 toward the inner end edge 50a.

  The fastening region 60 is formed from a hook element of a mechanical fastener, and can be fastened to the outer layer sheets 32 and 33 made of a fiber nonwoven fabric that form the outer surfaces of the front and rear waist regions 15 and 16. The fastening area 60 can also be formed from a pressure sensitive adhesive. The fastening region 60 is fastened to the intermediate portion 57 by bending the distal portion 56 where the fastening tape 50 is located toward the inner surface 53. In FIG. 5, an aspect of the distal portion 56 before being folded (or when unfolded) is indicated by an imaginary line. Alternatively, the fastening region 60 may be secured directly to the outer surface of the front waist region 15 without bending the distal portion 56, or the portion where the fastening region 60 is located during the manufacturing process of the diaper 10. The outer surface of the waist region 15 may be temporarily fixed by heat sealing or the like. By fastening or temporarily fastening the fastening region 60 in this way, for example, when the size adjusting means 12 is not used, the fastening region 60 is not worn by the wearer when the distal portion 56 is exposed from the cover member 51. There is no possibility that the body touches and irritate, and the fastening tape 50 is prevented from being exposed so as to unexpectedly jump out of the covering portion 67 of the cover member 51 while the diaper 10 is being transported or worn. can do.

The cover member 51 is formed from a known fiber nonwoven fabric, for example, a spunbond fiber nonwoven fabric, an SMS fiber nonwoven fabric, or an air-through fiber nonwoven fabric having a mass of about 10 to 40 g / m ² , preferably about 15 to 30 g / m ² . It has inner and outer layer sheets 63 and 64 and a cover elastic body 65 attached between the inner and outer layer sheets 63 and 64. The cover elastic body 65 extends in the length direction of the cover member 51, has a fineness of about 350 to 950 dtex, and is stretched by about 1.5 to 3.0 times from a contracted or relaxed state. Alternatively, it is formed from a strand-like elastic material. The inner and outer layer sheets 63 and 64 are formed from a single or separate sheet member.

  The cover member 51 includes an outer end edge (fixed edge) 51b fixed together with the outer end edge 50b of the fastening tape 50 at the side seam 22, and a concavely curved inner end facing the outer end edge 51b in the lateral direction X. It has a horizontally long rectangular shape defined by an edge (free edge) 51a and both side edges 51c that are spaced apart from each other in the longitudinal direction Y and extend in the lateral direction X. The cover member 51 further includes a seal portion (including the side seam 22) 66 joined to the chassis 11 by heat welding means, extending in a U shape along the outer end edge 51b and both side edges 51c, and between the seal portions 66. And a covering portion 67 that is not fixed to the chassis 11 surrounded by. A plurality of gathers 70 formed by contraction of the cover elastic body 65 are formed in the covering portion 67. The holding portion 61 of the fastening tape 50 is exposed outward from the inner end edge 51a so that the operator can hold it.

  The separation dimension (pitch) R1 between the cover elastic bodies 65 located in the covering portion 67 is about 10 to 30 mm. The covering portion 67 is disposed in the region where the second front waist elastic body 34B is present, and the separation dimension between the second front waist elastic body 34B located near the side edge 51c of the cover member 51 and the cover elastic body 65 adjacent thereto. (Pitch) R2 is about 10 to 30 mm. When the difference between the separation dimension R1 and the separation dimension R2 is about 0 to 10 mm, between the gather 40 formed in the separation part between the second front waist elastic body 34B and the cover elastic body 65 and the cover elastic body 65 The gathers 70 formed in the separated portions are substantially the same size in appearance in the vertical direction Y.

  4 and 5, the length dimension (the dimension in the lateral direction X) L1 of the fastening tape 50 is about 120 to 240 mm, and the width dimension (the dimension in the longitudinal direction Y) W1 is about 15 to 40 mm. The length dimension (dimension in the horizontal direction X) L2 of the member 51 is about 120 to 240 mm, and the width dimension (dimension in the vertical direction Y) W2 is about 40 to 80 mm. The lengths L1 and L2 of the fastening tape 50 and the cover member 51 are substantially equal, and almost the entire fastening tape 50 is covered with the covering portion 67, and the gather 70 is formed on the covering portion 67 of the cover member 51. As a result, the length of the fastening tape 50 is shrunk and the length of the fastening tape 50 is shortened, so that a part of the fastening tape 50 is exposed from the cover member 51. The fastening tape 50 can be easily pulled out from the inside of the cover member 51 by picking the exposed portion and pulling it inward.

  As described above, since almost the entire fastening tape 50 is covered with the covering portion 67 of the cover member 51, the outer shape of the fastening tape 50 does not appear outside, and the diaper 10 is a disposable diaper with a tape in appearance. It is hard to be recognized as, and an impression like a so-called underwear can be given to the wearer. However, as long as the entire outer shape of the fastening tape 50 is not exposed, the diaper 10 is not recognized as a disposable diaper with a tape, and at least the proximal portion 55 only needs to be covered. That is, even if at least the proximal portion 55 of the fastening tape 50 is covered with the covering portion 67 and a part of the intermediate portion 57 and the entire distal portion 56 are exposed from the covering portion 67, the fastening tape 50. Since the entire outer contour is not exposed, the wearing article 10 is not recognized as a disposable diaper with a tape instead of a pants-type diaper in appearance. Further, since at least the proximal portion 55 is covered, the entire length of the fastening tape 50 cannot be grasped from the outside, and the fastening tape 50 has a relatively large length. However, its existence does not stand out.

  Specifically, when the size adjusting means 12 is not used, that is, a natural state of the diaper 10 (for example, a state where the diaper is taken out from the package and left in an atmosphere of a temperature of 20 ° C. and a humidity of 60% HR for 60 minutes). It is preferable that about 50% or more of the entire surface area of the fastening tape 50 is covered with the covering portion 67 of the cover member 51. In such a case, even if a part of the fastening tape 50 is exposed, its presence is not clearly recognized. On the other hand, when about 50% or more of the surface area of the fastening tape 50 is exposed, the uniform appearance of the diaper 10 is impaired, and the fastening tape 50 is conspicuously recognized as a disposable diaper with a tape fastener. There is a fear.

  In addition, even if the entire fastening tape 50 is covered with the cover member 51, the diaper 10 is recognized as a disposable diaper with a fastening tape when the outline of the cover member 51 attached to the chassis 11 clearly appears. There is a risk. In particular, when the gathers 70 are not formed on the covering portion 67 that forms the outer surface of the size adjusting means 12, the gathering formed on the entire diaper 10 due to the contraction of the front waist elastic body 34 is locally eliminated (interrupted). Therefore, the presence of the size adjusting means 12 may be clearly visually recognized on the outer surface. In the case of the present embodiment, a plurality of gathers 40 due to the contracting action of the front waist elastic body 34 is formed on the entire front waist region 15 in which at least the size adjusting means 12 of the chassis 11 is disposed, and the cover Since a plurality of gathers 70 generated by the contracting action of the cover elastic body 65 are formed on the covering portion 67 of the member 51, the chassis 11 and the cover member 51 have a uniform appearance, and at first glance size. It is not recognized as a disposable diaper with adjusting means (cover member).

  Further, as described above, the size in the longitudinal direction Y of the gather 40 formed in the separated portion between the second front waist elastic body 34 </ b> B and the cover elastic body 65 and the gather formed in the separated portion between the cover elastic bodies 65. When the size in the vertical direction Y of 70 is substantially equal, the gathers 40 and 70 having the same size are formed continuously in the cover member 51 and the chassis 11, so the chassis 11 and the cover The boundary with the member 51 becomes unclear, and it becomes difficult to clearly distinguish the outline of the cover member 51 in the external view.

  In order to improve the uniform appearance on the appearance of the diaper 10, the expansion ratio of the cover elastic body 65 is 0.8 to 1.2 times the expansion ratio of the front waist elastic body 34 disposed in the front waist region 15. It is preferable. In such a case, there is no significant difference between the former and the latter, and the size of the gathers 40 and 70 formed on the entire outer surface of the diaper 10 is locally changed. This is because the sense of unity is not impaired.

  As described above, since the outer shape of the cover member 51 does not appear clearly in the appearance of the diaper 10, the wearer and the wear assistant have a function capable of adjusting the size by the tape element, and at the same time, the appearance like a pant. The diaper 10 can be worn as if wearing an underwear. That is, by making the presence of the size adjusting means 12 invisible in appearance, the wearer and the wearing assistant wear a disposable diaper, but wear a pants-type wearing article that seems to be more underwear. You can be satisfied that you are doing, and can play a role in providing mental support for a more active life.

  Referring to FIG. 6, the usage mode of the size adjusting means 12 will be described. When the diaper 10 is worn, the distal portion 56 of the fastening tape 50 covered or exposed by the covering portion 67 of the cover member 51 is gripped. Then, it is pulled inward, that is, in the direction of the arrow F <b> 1, and is fixed to the outer surface of the chassis 11. By fastening the fastening tape 50 to the outer surface of the chassis 11, both side edges of the proximal side 55 where the fixed side seam 22 is located are drawn inward, and the waist circumference of the diaper 10 is reduced. When contracted, the front and rear waist regions 15, 16 are more fit to the wearer's body.

  When the leg opening edge of the diaper 10 has a relatively large peripheral dimension with respect to the wearer's thigh, that is, a slightly spaced portion (gap between the upper edge of the leg opening edge and the thigh) ) Is formed, the leg opening edge does not fit the wearer's thigh, causing leakage of excrement. In particular, in a diaper for adults with different sizes of the wearer's body, such a situation is likely to occur. In this way, not only the front and rear waist regions 15 and 16 but also the size of the leg opening can be adjusted by the size adjusting means 12. By adjusting, leakage of body fluid can be prevented. However, the size adjusting means 12 can be used only for adjusting the size around the waist. In this case, the size of the front waist region 15 or the rear waist region 16 is not the both side portions 18 of the front waist region 15. You may be located near the center part, and may be located not around the leg opening but around the waist opening. Moreover, the size adjustment means 12 may be arrange | positioned according to the dimensional amount which needs size adjustment by single or multiple. Further, in the present embodiment, the size adjusting means 12 may be disposed so as to be inclined so as to intersect the horizontal center line Q when the size adjusting means 12 is disposed substantially parallel to the horizontal center line Q. Even when the size adjusting means 12 is disposed obliquely with respect to the horizontal center line Q, the cover elastic body 65 can exert a force to expand and contract in the horizontal direction X, so that the covering portion 67 and the outer surface of the diaper 10 The gathers 40 and 70 having a sense of unity are formed.

  In the present embodiment, since the cover elastic body 65 is attached to the cover portion 67 of the cover member 51, the cover portion 67 contracts when the fastening tape 50 is pulled in the direction of the arrow F1 and pulled out from the cover member 51. And since the length dimension shrinks, it is hard to disturb the drawer operation.

<Modification 1>
Referring to FIG. 7, in this embodiment, the seal portion 66 of the cover member 51 includes an end seal portion 66a that overlaps the side seam 22, and a side seal portion 66b that extends in the lateral direction X along both side edges 51c. Have The seal pattern of the end seal portion (same as the side seam 22) 66a and the seal pattern of the side seal portion 66b have the same shape composed of a plurality of dot-like debosses. These seal patterns may be different, but are preferably the same in consideration of unity in appearance. In the side seal portion 66b, the dot-shaped debosses extend to the chassis 11 so as to overlap the side edges 51c. As described above, since the seal pattern of the side seal portion 66b overlaps the side edge 51c of the cover member 51 and extends to the chassis 11, the boundary between the cover member 51 and the chassis 11 becomes unclear. The outer contour of 51 can be made indistinct, and the overall appearance of the diaper 10 can be improved.

  In addition, dots formed on the outer surface of the chassis 11 in the shape of a dot-shaped joint portion (for example, a circle, a rectangle, a star, or a geometric figure) located on the side edge 51c of the cover member 51 in the side seal portion 66b. It is preferable to have the same or similar shape as the shape joint. In such a case, it is possible to further improve the unity of the seal pattern and the overall appearance of the diaper 10.

  Furthermore, at least the outer layer sheet 64 of the inner and outer layer sheets 63 and 64 forming the cover member 51 is formed from the same type of fiber nonwoven fabric as the outer layer sheets 32 and 33 forming the outer surface of the chassis 11 (for example, both sheets are air-through). It is preferable that the main fibers have the same orientation (both extend in the longitudinal direction Y (or in the lateral direction X)). In such a case, the shape and size of the gathers 40 and 70 formed on the outer surface of the chassis 11 and the outer surface of the cover member 51, the texture and feel of the sheet can be more approximated, and the overall appearance of the diaper 10 can be unified. This is because the feeling can be further improved. The following measurement method was used for fiber orientation. The fiber orientation includes a case where all the fibers are oriented in one direction and a case where the fibers are oriented in parallel or randomly and are oriented in one direction in proportion.

<Measurement of orientation>
The outer layer sheets 32, 33, and 64 are cut into a vertical sample piece by cutting to a dimension of 60 mm in the longitudinal direction Y and a dimension of 10 mm in the lateral direction X. After cutting, the breaking strength of each of the vertical sample piece and the horizontal sample piece was measured as a horizontal sample piece. The measurement was performed using a tensile tester (Instron). The distance between grips of the testing machine was set to 100 mm, both ends in the longitudinal direction of the vertical sample piece and the horizontal sample piece were held between grips, the sample piece was pulled at a speed of 100 mm / min, and the maximum strength at break was measured. The orientation was determined by the following formula.

Sheet breaking strength = maximum breaking strength of horizontal (or vertical) sample piece / maximum breaking strength of vertical (or horizontal) sample piece × 100

Such measurements show, for example, that the fibers are oriented in the longitudinal direction if the maximum breaking strength of the longitudinal sample piece is higher than that of the transverse sample piece, so check the breaking strength of each sample in the longitudinal direction. It was confirmed whether the fibers were oriented in the lateral direction.

<Modification 2>

<Modification 3>
FIG. 9 is a diagram showing a state in which the fastening tape 50 is pulled out from the cover member 51 in an example of still another modification of the fastening tape 50, and FIG. 10 is still another modification of the fastening tape 50. It is a figure which shows the mode of the use condition in an example. In the fastening tape 50 according to the present embodiment, the fastening region 60 is located on the outer surface 54 instead of the inner surface 53 of the distal portion 56. The method of using the size adjusting means 12 having such a mode will be described. First, the operator holds the gripping portion 61 with one hand and pulls the fastening tape 50 in the direction of the arrow F so that the fastening area 60 is used. In addition to releasing the fastening, the cover member 51 is pulled out and pulled as it is to eliminate the slack in the leg opening edge and fit the inner surface of the leg opening edge to the wearer's thigh (first step). Referring to FIG. 10, next, while maintaining the state where the fastening tape 50 is pulled inward, it is folded and the waist opening side through the folded inner end edge (folded guide edge) 50a of the cover member 51 The fastening area 60 is fastened to the outer surface of the front waist area 15 by pulling in the F2 direction (second step). As a result, the side edge of the front waist region 15 is drawn inward, and the dimensions of the cover member 51 are reduced. The direction of folding back is not limited to the diagonally upward direction, but may be reversed 180 degrees to secure the fastening area 60 on the outer surface of the cover member 51, or may be reversed diagonally and secured to the clothing facing surface of the diaper 10. May be. Thus, in order to maintain the state of the first step, it is not necessary to hold the front waist region 15 with the other hand, and the wearer / wearing assistant needs to attach the fastening tape 50 to the first step and the second step. It can be operated relatively easily with one hand in succession.

  In such a configuration, the inner end edge 66c of the seal portion 66 of the cover member 51 is positioned so as to overlap the side edge portion of the liquid absorbing structure 43 of the absorbent panel 14 in a plan view of the wearing article. The liquid-absorbing structure 43 has a relatively large thickness dimension, and has higher rigidity (also referred to as semi-rigidity) than other sheet members, and in particular, the side edge portion does not conform to the wearer's body shape. Where the gap is easily formed, the inner end edge 66c of the seal portion 66 is positioned so as to overlap with the liquid absorbing structure 43 in plan view, thereby preventing the side edge of the liquid absorbing structure 43 from being lifted. Can adhere to the skin. In other embodiments, similarly, it is preferable that the inner end edge 66c of the seal portion 66 is positioned so as to overlap with the side edge portion of the liquid absorbing structure 43 in plan view.

Have A continuous elastic body 103 corresponding to the front and rear waist elastic bodies 34 and 35 is disposed inside the first and second composite panels 101 and 102.

  In the composite panel 100 having such a configuration, a continuous band 105 serving as a base material for the two fastening tapes 50 is intermittently arranged in the machine direction MD on the other surface side of the first composite panel 101. The continuous band 105 is temporarily fixed at the joint portion 106 by heat sealing or hot melt adhesive at both ends 105a and 105b facing each other in the center portion and the machine direction MD. Next, an elastic sheet (corresponding to two cover members 51) 110 having a plurality of elastic bodies 111 extending in the machine direction MD is disposed so as to cover the continuous band 105. Both sides of the elastic sheet 110 extending in the machine direction MD are joined to the first composite panel 101 by known joining means 112 such as heat embossing or hot melt adhesive. Next, the composite panel 100 is arranged such that the continuous band 105 faces the outside along a folding line T that bisects the dimension in the cross direction CD of the composite panel 100 (so that one side of the absorbent panel 14 faces each other). Is folded in half and conveyed. The overlapping portions (first composite panel 101 and second composite panel 102) of the folded composite panel 100 are joined to each other by a pair of joining lines 113 extending in the cross direction CD. Next, a plurality of diapers 10 can be continuously manufactured by cutting the composite panel 100 along the cutting line 108 extending in the cross direction CD between the bonding lines 113.

  In this way, the continuous band 105 is attached to the composite panel 100 serving as the base material of the chassis 11 while being transported in the machine direction MD, and the cutting of the size adjusting means 12 and the cutting of the main body of the diaper 10 are simultaneously performed in a single cutting process. be able to. Compared to a case where a fastening tape and a cover member are separately attached to each of the diaper main bodies cut from the composite panel 100, the manufacturing can be simplified. Moreover, in the manufacturing process, the continuous band 105 can be transported smoothly in the machine direction MD without being displaced by temporarily fixing the continuous band 105 at a plurality of locations by the central portion and the both end portions 105a and 105b.
