As disclosed in Japanese Patent Application Laid-Open No. 207605, a vertically long main body including a liquid-permeable top sheet, a liquid-impermeable back sheet, and an absorber interposed between these sheets is provided. Are divided into an abdominal part located on the ventral side of the wearer and a dorsal part located on the dorsal side when worn. Then, in the pair of left and right side flaps formed on both sides along the longitudinal direction of the main body, the ventral side portion and the back side portion are joined and fixed to each other to form a pair of left and right leg openings and one waist opening. ..

成人用として用いられている。This type of pants-type diaper is constructed so that a pair of leg openings and one waist opening are formed to be expandable and contractable so as to fit the body shape.
Since the wearer himself can wear it while standing,
It is used for toilet training to promote infant's "diaper separation" or for incontinence or ambulatory adults.

性を有することが要求される。The pants-type diaper is characterized in that it is easier for the wearer to raise and lower by himself and to be worn by a caregiver as in ordinary underwear, as compared with a so-called flat-type diaper. To prevent the excrement from leaking,
In addition, the pants-type diaper is required to have excellent fit in order to be easily worn. Furthermore, it is required to have sufficient followability to the active activity of the wearer.

おむつとして実用的ではなかった。However, in the conventional pants-type diaper, since the bending rigidity of the absorber portion of the pants-type diaper is considerably high and thick, the absorber does not have a good fit with the body when worn. Became a cause of leakage of excrement. In addition, a thin product similar to normal underwear is commercially available for toilet training, but it is not practical as a diaper because its liquid absorption capacity is extremely low.

ある。SUMMARY OF THE INVENTION The present invention comprises a liquid-permeable top sheet, a liquid-impermeable back sheet, and an absorber arranged between these sheets, and is provided on the ventral side of the wearer. The side edges of the ventral side portion and the back side portion located on the back side are joined and fixed to form a waist opening and a pair of leg openings, and the waist opening and the leg openings are substantially formed. In a pants-type diaper having an upper continuous gather, the absorber has (1) a bending elasticity of 20 g.
This is achieved by providing a pants-type diaper characterized in that the thickness is cm or less, (2) its thickness is 5.0 mm or less, and (3) its liquid absorption capacity is 300 g / piece or more.

さと相まって充分に確保される。According to the pants-type diaper of the present invention, since the bending elasticity of the absorber is suppressed to be low and the thickness is thin, as shown in FIG. It doesn't happen that the waist gathers over the abdomen. In addition, the gathers at the leg openings are not covered and do not come into contact with the crotch. That is, even when sitting, the absorber follows the abdominal part and the dorsal part and can sufficiently cover the excretion site. Therefore, the leakproofness on the absorbing surface of the absorber is sufficiently ensured in combination with the high liquid absorption capacity of the liquid of the absorber.

I was there. The flexural elasticity is measured according to the stiffness test method of paperboard by the load bending method (JIS P8125), and the liquid absorption capacity is measured by putting the absorbent body in a non-woven fabric bag and immersing it in physiological saline solution. After soaking for 1 minute, the mesh was allowed to stand for 3 hours and the weight of the physiological saline solution absorbed was measured.

ギャザー１４を設けた効果が充分にみられる。The pants-type diaper having the thin absorber 4 is provided with an elastic member around the waist of the wearer between the waist opening 8 and the leg opening 9 in order to further improve the fit with the body. Preferably. In the pants-type diaper 1 according to this embodiment, the waistline gathers 14, 14, 14 are stretched as described above. In the present embodiment configured as described above, FIG. 3 shows the state of the pants-type diaper 1 when it is worn in a sitting position. As shown in FIG. 3, the waistline portion 20 of the ventral side portion 6 of the pants-type diaper 1 is shown.
Also, the crotch portion 22 does not come into contact with the body. Further, it can be seen that the absorber 4 follows the abdomen and back of the body through the top sheet 2 when sitting. Further, the effect of providing the waist gathers 14 can be sufficiently seen.

It can also absorb body fluid sufficiently. Next, another embodiment of the present invention will be described with reference to FIG.
And it demonstrates according to FIG. FIG. 4 is a development view in which joining and fixing portions of both side edges of a pant-type diaper according to another embodiment are separated from each other, and FIG. 5 is a cross-sectional view of a main portion provided with a solid gather.

吸収容量が５００ｇ／枚である点である。The pants-type diaper according to the present embodiment is constructed in substantially the same manner as the embodiment shown in FIG. 1, and the same members as those in the embodiment shown in FIG. 1 are designated by the same reference numerals in FIG. Although detailed description thereof will be omitted, the difference from the embodiment of FIG. 1 lies in that between the leg opening gather 11 and the longitudinal side edge 4a of the absorber 4 (or on the side edge in the absorber longitudinal direction). However, the three-dimensional leg gathers 15 that can come into contact with the wearer's groin area when worn.
And the absorbent body 4 is composed of a mixed layer in which 200 g / m 2 of pulp and 200 g / m 2 of super-absorbent polymer are mixed, the bending elasticity is 10 g · cm, the thickness is 4 mm, and the liquid absorption capacity is Is 500 g / sheet.

Was found to touch the body. (Comparative Example 2) Absorber with 500 g / m 2 of pulp and 150 g
A pants-type diaper was produced in the same manner as in the example except that a sandwich layer having a superabsorbent polymer of / m 2 was used, and the bending elasticity was 8 g · cm and the thickness was 8 mm.
