To assemble into a pants-type absorbent article 1 as shown in FIG.

(Absorbent body)
Next, the absorbent main body 2 used in the pants-type absorbent article 1 will be described in detail with reference to FIGS. 2 and 3.
FIG. 3 is a sectional view taken along the line II of FIG.

  As shown in FIGS. 2 and 3, the absorbent main body 2 includes a liquid-permeable top sheet 21 disposed closest to the body and a liquid-impermeable top sheet facing the top sheet 21 and disposed closest to the garment. , And an absorber 23 disposed between the top sheet 21 and the back sheet 22. Thereby, the absorber 23 has a structure sandwiched between the top sheet 21 and the back sheet 22.

  The top sheet 21 allows body fluid to pass quickly toward the absorber 23, and is disposed to face the back sheet 22 with the absorber 23 interposed therebetween. Since the top sheet 21 is a sheet that comes into contact with the skin, it has a soft feel and does not irritate the skin, and is formed of a hydrophilic nonwoven fabric, an opening film such as an open polyethylene film, or a foaming material such as urethane foam. It is formed from a film or a composite sheet obtained by laminating these films. The top sheet 21 may be a single layer or a plurality of layers, and may have a large number of through holes for imparting dry touch properties.

  Further, as the hydrophilic nonwoven fabric having the above properties, synthetic fibers such as polypropylene and polyethylene, regenerated fibers such as rayon, and natural fibers such as cotton, using a thermal bond method, an air-through method, a spunlace method, Those obtained by a known processing method such as a spun bond method can be used. The top sheet 21 may be coated with a lotion, an antioxidant, an anti-inflammatory component, a pH adjuster, an antibacterial agent, a humectant, etc. in order to reduce irritation to the skin.

  As the back sheet 22, a sheet material having liquid impermeability and having water blocking properties is used, but may have moisture permeability to prevent stuffiness. As a material of the back sheet 22 having such characteristics, for example, a plastic sheet having a small thickness such as a polyethylene sheet or a polyethylene laminated nonwoven fabric can be exemplified.

  The absorber 23 used for the absorbent main body 2 of the present embodiment is formed in a substantially square or substantially rectangular shape in a plan view, and includes an absorbent core 231 for absorbing bodily fluids such as urine, and an absorbent core 231 for absorbing the bodily fluid. And a carrier sheet 232 that covers the core 231 so as to surround it.

  The absorbent core 231 contains absorbent fibers as a base material and a highly absorbent polymer. The absorbent fiber is not particularly limited as long as it is generally used for the pants-type absorbent article 1, and examples thereof include fluff pulp, cotton, rayon, acetate, tissue, absorbent paper, and hydrophilic nonwoven fabric. . Among these, it is preferable to use fluff pulp from the viewpoint of absorbability. Examples of such fluff pulp include wood pulp, synthetic fiber, polymer fiber, non-wood pulp, and the like that are defibrated into cotton.

  The superabsorbent polymer is not particularly limited as long as it is capable of absorbing body fluid and preventing backflow, and includes sodium polyacrylate, polyaspartate, (starch-acrylic acid) graft copolymer, Those formed from materials such as (acrylic acid-vinyl alcohol) copolymer, (isobutylene-maleic anhydride) copolymer and saponified product thereof can be used. Among them, sodium polyacrylate is preferred from the viewpoint of the amount of absorption per weight.

  The carrier sheet 232 may cover the entire absorbent core 231 or may cover the absorbent core 231 from above and below. By covering the absorbent core 231 with the carrier sheet 232, the shape of the absorbent core 231 can be maintained, and additionally, the superabsorbent polymer can be prevented from leaking out of the absorber 23. Examples of the carrier sheet 232 include a tissue, an absorbent paper, a hydrophilic non-woven fabric such as a spun-bonded non-woven fabric and an air-laid non-woven fabric, and it is preferable to use a tissue from the viewpoint of liquid diffusibility, water retention, and cost.

  It is preferable that three-dimensional gathers are provided on the body-side surface of the absorbent main body 2 (not shown). The three-dimensional gather forms a confined space for bodily fluids together with the top sheet 21 so that leakage of bodily fluids can be prevented.

(Exterior)
Next, the exterior body 3 used for the pants-type absorbent article 1 will be described in detail with reference to FIGS. 1 to 3.

  As shown in FIGS. 1 to 3, the exterior body 3 has an inner layer sheet 34 on the body side when the pants-type absorbent article 1 is worn and an outer layer sheet 35 on the clothes side when the pants-type absorbent article 1 is worn. It is configured as follows. In addition, the inner layer sheet 34 and the outer layer sheet 35 are formed of a nonwoven fabric sheet having a dimension in the thickness direction of 0.3 mm or more and 0.6 mm or less, and formed such that the fiber orientation is in the width direction. . Further, a thread-like elastic member described later is arranged between the inner layer sheet 34 and the outer layer sheet 35 so as to impart elasticity.

  Further, the exterior body 3 is formed in a substantially hourglass shape when viewed in a plan view (development view), and includes a crotch portion 33 that covers the crotch of the wearer when worn, and is positioned in front of the crotch portion 33 and worn when worn. An abdomen 31 covering the abdomen of the wearer, a back 32 positioned behind the crotch 33 and covering the back of the wearer when worn, and extending longitudinally on both sides of the abdomen 31 and the back 32 in the width direction. It has long side edges 38 formed integrally with the abdomen 31 and the back 32 so as to extend along the direction. That is, the crotch part 33 is provided so as to connect the abdominal part 31 and the dorsal part 32. The absorbent main body 2 is provided so as to cover at least the crotch 33.

  The abdomen 31 has a first elastic member region 31a (waist gather) disposed on the end side of the waist opening 4 and a leg opening 5 (longer than the first elastic member region 31a along the longitudinal direction). It has a second elastic member region 31b (fit gather) arranged on the crotch portion 33) side and a non-elastic member region 31c arranged between the first elastic member region 31a and the second elastic member region 31b. I have. That is, the first elastic member region 31a, the non-elastic member region 31c, and the second elastic member region 31b are sequentially arranged from the end of the waist opening 4 toward the leg opening 5 (the crotch 33). It has become so.

  In the first elastic member region 31a, a plurality of thread-like waist elastic members 36 (first elastic members) extending along the width direction are arranged at predetermined first intervals along the longitudinal direction. . These waist elastic members 36 are provided with elasticity so as to tighten around the waist of the wearer. The first elastic member region 31a and the waist elastic member 36 form a waist gather.

  In the second elastic member region 31b, a plurality of thread-like waist elastic members 37 (second elastic members) extending along the width direction are arranged at predetermined second intervals along the longitudinal direction. I have. These waist elastic members 37 are provided with elasticity so as to tighten around the waist of the wearer. The second elastic member region 31b and the waist elastic member 37 form a fit gather.

  In the present embodiment, the first interval is formed so as to be smaller than the second interval (that is, the arrangement density of the waist elastic members 36 is larger than the arrangement density of the waist elastic members 37). However, the present invention is not limited to this, and may be formed to be equal to the second interval or to be larger than the second interval as necessary.

  The inelastic member region 31c is a long member provided so as to extend along the width direction in plan view, and has no elastic member or the like. In addition, the dimension of the inelastic member region 31c in the longitudinal direction is preferably 20 mm or more, and more preferably 25 mm or more and 40 mm or less. It goes without saying that the dimension of the inelastic member region 31c in the longitudinal direction is significantly larger than any of the first interval and the second interval.

  The length of the second elastic member region 31b in the longitudinal direction is formed to be larger than the length of the first elastic member region 31a in the longitudinal direction.

  The back side portion 32 has a first elastic member region 32a (waist gather) arranged on the end side of the waist opening 4 and a leg opening 5 (longer than the first elastic member region 32a along the longitudinal direction). It has a second elastic member region 32b (fit gather) disposed on the crotch portion 33) side and a non-elastic member region 32c disposed between the first elastic member region 32a and the second elastic member region 32b. I have. That is, the first elastic member region 32a, the non-elastic member region 32c, and the second elastic member region 32b are sequentially arranged from the end side of the waist opening 4 toward the leg opening 5 (the crotch 33). It has become so.

  In the first elastic member region 32a, a plurality of thread-like waist elastic members 36 (first elastic members) extending along the width direction are arranged at predetermined first intervals along the longitudinal direction. . These waist elastic members 36 are provided with elasticity so as to tighten around the waist of the wearer. The first elastic member region 32a and the waist elastic member 36 constitute waist gathers.

  In the second elastic member region 32b, a plurality of thread-like waist elastic members 37 (second elastic members) extending in the width direction are arranged at predetermined second intervals in the longitudinal direction. I have. These waist elastic members 37 are provided with elasticity so as to tighten around the waist of the wearer. Note that the second elastic member region 32b and the waist elastic member 37 constitute a fit gather.

  In the present embodiment, the first interval is formed so as to be smaller than the second interval (that is, the arrangement density of the waist elastic members 36 is larger than the arrangement density of the waist elastic members 37). However, the present invention is not limited to this, and may be formed to be equal to the second interval or to be larger than the second interval as necessary.

  The non-elastic member region 32c is a long member provided so as to extend in the width direction in plan view, and has no elastic member or the like. Further, the dimension of the inelastic member region 32c in the longitudinal direction is preferably 20 mm or more, and more preferably 25 mm or more and 40 mm or less. It is needless to say that the dimension of the inelastic member region 32c in the longitudinal direction is significantly larger than any of the first interval and the second interval.

  The length of the second elastic member region 32b in the longitudinal direction is formed to be larger than the length of the first elastic member region 32a in the longitudinal direction.

  As shown in FIGS. 1 and 2, both side edge portions 38 include a non-joining portion 38 a arranged in a region in the longitudinal direction of the non-elastic member regions 31 c and 32 c, and a waist opening 4 that is larger than the non-joining portion 38 a Side seal portion 38b arranged on the side, the second side seal portion 38c arranged closer to the leg opening 5 than the non-joined portion 38a, and arranged on the outer edge side in the width direction than the non-joined portion 38a. And a third side seal portion 38d.

  As shown in FIG. 2, the body side in the width direction of the non-joining portion 38a, the first side seal portion 38b, and the body side in the width direction of the second side seal portion 38c are a first straight line extending along the longitudinal direction. The second straight line which is provided on the upper side, and the outer edge side in the width direction of the third side seal portion 38d and the first side seal portion 38b and the outer edge side in the width direction of the second side seal portion 38c are parallel to the first straight line. It is provided above.

  The non-joining portion 38a connects the body side in the width direction of the first side seal portion 38b and the body side in the width direction of the second side seal portion 38c along the longitudinal direction. The inelastic member regions 31c, 32c and the third side seal portion 38d extend along the width direction so as to be connected to the widthwise ends of the first and second side seal portions 31c, 32c and the third side seal portion 38d. It is located between them. Further, since the non-joining portion 38a is disposed in the region in the longitudinal direction of the non-elastic member regions 31c and 32c, the dimension in the longitudinal direction is preferably 20 mm or more, more preferably 25 mm or more and 40 mm or less. preferable.

  By setting the longitudinal dimension of the non-joining portion 38a to the above range, a finger can be reliably inserted into the non-joining portion 38a from the waist opening 4 when worn. If the length in the longitudinal direction of the non-joined portion 38a exceeds 40 mm, the strength of the pants-type absorbent article 1 may not be sufficiently obtained at the time of wearing, and may be peeled off. If the length of the non-joined portion 38a in the longitudinal direction is less than 20 mm, there is a possibility that a finger cannot be inserted into the non-joined portion 38a successfully.

  The first side seal portion 38b is provided so as to extend along the longitudinal direction from the end of the waist circumference opening 4 to one end (the upper end in FIG. 2) of the non-joining portion 38a. It is preferable that the dimension is in the range of 4 mm or more and 7 mm or less.

  The second side seal portion 38c is provided so as to extend along the longitudinal direction from the end of the leg opening 5 to the other end (the lower end in FIG. 2) of the non-joining portion 38a. It is preferable that the dimension be substantially the same as the dimension of the first side seal portion 38b in the width direction and be in the range of 4 mm or more and 7 mm or less.

  By setting the width dimension of the first side seal portion 38b or the second side seal portion 38c in the above range, sufficient strength can be obtained when worn, and the side edges 38 are easily torn during disposal. Thus, the pants-type absorbent article 1 can be easily removed.

  When the width direction dimension of the first side seal portion 38b or the second side seal portion 38c exceeds 7 mm, the orientation of the fibers of the inner layer sheet 34 and the outer layer sheet 35 constituting the exterior body 3 becomes the width direction, so that the bonding portion is formed. The width dimension of the first side seal portion 38b or the second side seal portion 38c as described above is too long, so that the fibers are not easily cut at the time of disposal, and the side edges 38 are not easily torn. Further, when the width dimension of the first side seal portion 38b or the second side seal portion 38c is less than 4 mm, sufficient strength cannot be obtained when worn, and the first side seal portion 38b or the second side seal portion 38c is not provided. It becomes difficult to recognize the difference from the non-joined portion 38a.

  The third side seal portion 38d is for connecting the outer edge side in the width direction of the first side seal portion 38b and the outer edge side in the width direction of the second side seal portion 38c along the longitudinal direction. The dimension in the direction is preferably in the range of 45% or more and 55% or less.

  Further, it is preferable that the dimension in the width direction of the non-joining portion 38a is in a range of 45% to 55% of the dimension in the width direction of the first side seal portion 38b or the second side seal portion 38c. By setting the dimension of the non-joined portion 38a in the width direction to the above range, the position of the non-joined portion 38a can be easily recognized, and the third side seal portion 38d can be easily fused.

  If the dimension in the width direction of the non-joining portion 38a exceeds 55% of the dimension in the width direction of the first side seal portion 38b or the second side seal portion 38c, the dimension in the width direction of the third side seal portion 38d becomes too small. Thus, the third side seal portion 38d is less likely to be fused. If the dimension in the width direction of the non-joining portion 38a is smaller than 45% of the dimension in the width direction of the first side seal portion 38b or the second side seal portion 38c, the first side seal portion 38b or the second side seal portion 38c. The difference between the non-joined portion 38a and the position of the non-joined portion 38a is difficult to recognize.

  The side edges 38 of the abdominal part 31 and the side edges 38 of the back part 32 are fused by using a known method such as heat sealing or ultrasonic sealing. At this time, the non-joined portion 38a of the abdomen 31 and the non-joined portion 38a of the back 32 are not fused.

(Effect of this embodiment)

A waist opening 4 and a pair of left and right leg openings 5 are formed, and the abdominal part 31 and the back part 32 are both arranged on the end side of the waist opening 4. The first elastic member regions 31a and 32a where the waist elastic member 36 is arranged, and the second where the waist elastic member 37 is arranged closer to the leg opening 5 than the first elastic member regions 31a and 32a. Elastic member regions 31b, 32b and first elastic member regions 31a, 32a And non-elastic member regions 31c, 32c disposed between the second elastic member regions 31b, 32b, and the both side edge portions 38 are provided in non-elastic member regions 31c, 32c in the longitudinal direction. A first side seal portion 38b disposed closer to the waist opening 4 than the non-joint portion 38a, and a second side seal portion disposed closer to the leg opening 5 than the non-joint portion 38a. 38c, and a third side seal portion 38d that is arranged closer to the outer edge in the width direction than the non-joined portion 38a and connects the first side seal portion 38b and the second side seal portion 38c along the longitudinal direction. Things. Thus, by disposing the non-joining portion 38a on the inner edge side of the both side edge portions 38 in the region in the longitudinal direction of the non-elastic member regions 31c, 32c, a hand is inserted from the waist opening 4 at the time of disposal, and the finger is used. By touching the inner edges of the side edges 38, the non-joined portion 38a can be easily found, and then the finger can be easily inserted into the non-joined portion 38a. Then, the second side seal portion 38c and the third side seal portion 38d can be easily torn, and then the opening formed by the tearing is widened from the outside of the waist opening 4, so that the welding pattern of the side seal portion can be changed. Since the side seal portion can be peeled along the longitudinal direction with a light force without a special shape, the pants-type absorbent article 1 can be easily removed. Kill.

  Also, since the third side seal portion 38d connects the first side seal portion 38b and the second side seal portion 8c, the non-joined portion 38a is covered by the third side seal portion 38d, so that the pants-type absorbent article 1 can maintain the aesthetic appearance.

  As described above, the present invention has been described using the embodiments. However, it is needless to say that the technical scope of the present invention is not limited to the scope of the above embodiments, and various changes or improvements may be made to the above embodiments. It is clear to a person skilled in the art that is possible. It is apparent from the description of the claims that the embodiments with such changes or improvements can be included in the technical scope of the present invention.
