高めたものが知られている。2. Description of the Related Art A conventional disposable diaper includes a liquid-permeable top sheet and a liquid-impermeable back sheet, as disclosed in, for example, Japanese Patent Publication No. 52-40267.
A diaper body is composed of an absorbent body located between these two sheets, and elastic members are arranged on side flaps extending to the left and right of the diaper body to form gathers, and the back side of the side flaps. Generally, a so-called flat type diaper intended to improve fitability and leakproofness is provided by disposing a fastener on both side edges of the diaper so as to be adjustable. Further, as disclosed in Japanese Patent Laid-Open No. 62-250201, it is known that the gathers of the leg portions are made three-dimensional, and the flap portions around the absorber are made water repellent to enhance the leakproof effect. .

る。However, recently, as disclosed in Japanese Patent Laid-Open No. 57-77304, the abdominal region and the dorsal region of a pair of left and right side flaps are mutually opposed for the purpose of improving fit and wearability. A so-called pants-type disposable diaper in which a pair of left and right leg openings and a waist opening are formed by joining and fixing is proposed. The pants-type disposable diaper is configured such that the leg opening and the waist opening are formed to be expandable and contractable to fit the body shape. Such pants-type disposable diapers can usually be worn by the wearer himself in an upright position, for toilet training to promote "diaper separation" of infants, or for incontinent or ambulatory persons. It is said to be useful for possible adult use.

があるという問題があった。However, in the conventional pants-type disposable diaper described above, since the crotch part has to be formed narrow, the elastic elastic member cannot be arranged apart from the absorbent body. As a result, it was difficult to exhibit the original stretchable physical properties due to the influence of the rigidity of the absorber. At the same time, wrinkles and gaps are likely to occur at the joint portions of the both side edge portions due to the elastic elastic member, which causes excrement to leak. In addition, there is a problem in that the leg gather is three-dimensionally effective as a leakage prevention measure because the crotch is narrow and it is difficult to manufacture.

とともに、不経済である。A peripheral water-repellent technique which is effective as a measure for preventing leakage of excrement, especially urine, also has a narrow crotch part in a pants-type diaper, which clearly distinguishes the hydrophilic part from the water-repellent part. Since it cannot be formed, a sufficient effect could not be exhibited. Further, the conventional disposable diaper absorbs and retains excrement only in the vicinity of the urination point, only such a portion is soiled, and other portions, for example, the side portions of the waist are not substantially soiled. Therefore, throwing away the entire diaper is wasteful and uneconomical.

Another object of the present invention is to provide a disposable diaper in which only the soiled portion due to excrement can be replaced.

Pants type in which the side edges of the side flaps 8 and 9 of the outermost sheet 2 in the unfolded state shown in FIG. 2 are joined to each other to form a waist opening 11 and a pair of leg openings 7 and 7 as shown in FIG. Form a diaper. The outermost layer sheet 2 has an absorptive main body 3 adhered to the inside by an adhesive A so as to be peelable. At the time of wearing, the pants-type diaper is pulled up by passing both legs through the waist opening 11 and passing through the legs through the leg openings 7, 7. During wearing, the waist flap gathers 12a in the waist opening 11 of the outermost layer sheet 3 and the leg openings 7, 7 are first in the leg openings 7, 7.
The leg gathers 24a are formed, and are designed to have a fit to the wearer, followability, and leakage prevention. Further, the fourth stretchable elastic member 14 improves the fit of the wearer around the waist. Further, as shown in FIG. 3, since the absorbent main body 3 is adhered to the outermost layer sheet only at the central portion thereof, the second elastic elastic member 26
Since the main body flap 18 is easily erected to form a bag-like shape, excrement can be reliably held in the bag-like portion.

易におこなうことができる。Further, in the absorbent main body 3, the second leg gathers 26a are formed to prevent excrement and the like from leaking from the absorbent main body 3 to the outermost layer sheet 2. Further, since the double gathers are formed together with the first leg gathers 24a of the leg openings 7, 7 of the outermost layer sheet 2, leakage from the leg portions is surely prevented. Moreover, since the central portion 20 in the transverse direction of the outermost layer sheet 2 is formed of a single-layer fibrous sheet and the single-layer sheet 21 supports the absorbent main body 3, moisture permeability is not impaired and unevenness during wearing is prevented. While being prevented, the fit to the wearer in the crotch is enhanced. On the other hand, since the side edge portions 22 forming the leg gathers 26 are formed of the plural fiber sheets 23a and 23b and the support film 27, bleeding leakage of urine from these portions is surely prevented. Then, after excretion of the excrement, the absorbent main body 3 is peeled off from the outermost layer sheet 2, and a new absorbent main body 3 is bonded to the outermost layer sheet 2 with the adhesive A and replaced. Thus, according to the first embodiment, it is possible to easily replace only the absorbent main body that is soiled with excrement.

高めたものが知られている。2. Description of the Related Art A conventional disposable diaper includes a liquid-permeable top sheet and a liquid-impermeable back sheet, as disclosed in, for example, Japanese Patent Publication No. 52-40267.
A diaper body is composed of an absorbent body located between these two sheets, and elastic members are arranged on side flaps extending to the left and right of the diaper body to form gathers, and the back side of the side flaps. Generally, a so-called flat type diaper intended to improve fitability and leakproofness is provided by disposing a fastener on both side edges of the diaper so as to be adjustable. Further, as disclosed in Japanese Patent Laid-Open No. 62-250201, it is known that the gathers of the leg portions are made three-dimensional, and the flap portions around the absorber are made water repellent to enhance the leakproof effect. .

る。However, recently, as disclosed in Japanese Patent Laid-Open No. 57-77304, the abdominal region and the dorsal region of a pair of left and right side flaps are mutually opposed for the purpose of improving fit and wearability. A so-called pants-type disposable diaper in which a pair of left and right leg openings and a waist opening are formed by joining and fixing is proposed. The pants-type disposable diaper is configured such that the leg opening and the waist opening are formed to be expandable and contractable to fit the body shape. Such pants-type disposable diapers can usually be worn by the wearer himself in an upright position, for toilet training to promote "diaper separation" of infants, or for incontinent or ambulatory persons. It is said to be useful for possible adult use.

いて困難があるという問題があった。However, in the conventional pants-type disposable diaper described above, since the crotch part has to be formed narrow, the elastic elastic member cannot be arranged apart from the absorbent body. As a result, it was difficult to exhibit the original stretchable physical properties due to the influence of the rigidity of the absorber. At the same time, wrinkles and gaps are likely to occur at the joints of the both side edges due to the elastic member, which causes leakage of excrement. In addition, there is a problem in that the leg gather is three-dimensionally effective as a leakage prevention measure because the crotch is narrow and it is difficult to manufacture.

とともに、不経済である。A peripheral water-repellent technique which is effective as a measure for preventing leakage of excrement, especially urine, also has a narrow crotch part in a pants-type diaper, which clearly distinguishes the hydrophilic part from the water-repellent part. Since it cannot be formed, a sufficient effect could not be exhibited. Further, the conventional disposable diaper absorbs and retains excrement only in the vicinity of the urination point, only such a portion is soiled, and other portions, for example, the side portions of the waist are not substantially soiled. Therefore, throwing away the entire diaper is wasteful and uneconomical.

Another object of the present invention is to provide a pants-type disposable diaper in which only the soiled portion due to excrement can be replaced.

The leg openings of the pant-type outermost layer sheet fit the legs of the wearer by the first leg gathers, so that the leakage from these portions is surely prevented. Further, since the central portion of the outermost layer sheet is composed of only a single-layer fibrous sheet, the central portion is excellent in moisture permeability, and it is possible to prevent unevenness during wearing. Moreover, since the first leg gather portion is composed of a plurality of fibrous sheets, the leakage of urine from the first leg gather is surely prevented. Furthermore, since the central portion of the outermost layer sheet is formed as a single layer, the portion has excellent followability to the crotch of the wearer.
