2. Description of the Related Art Conventionally, disposable so-called training pants provided with wetness detecting means have been known. For example, Japanese Utility Model Laid-Open No. 5-19305 discloses that a moisture holding sheet is provided as a wetness detecting means on the skin contact surface of the training pants, and Japanese Utility Model Application Laid-Open No. 7-33916 discloses that the skin contact surface of the training pants is provided. Both ends of the stretchable wet holding sheet are fixed, and the wet holding sheet between these ends is temporarily bonded with a water-soluble adhesive, and when the sheet comes into contact with urination, the wet holding sheet is brought into contact with the skin contact surface. Disclosed is a configuration in which it is separated from and lifted up, and elastically presses against the crotch of an infant.

[0003]

The known wetness sensing means can achieve its intended purpose to some extent as long as the wettability sheet is in full contact with the infant's crotch. However, when the training pants are worn, generally, the central portion of the wet holding sheet does not come in close contact with the infant's crotch, and when the training pants move down due to the operation of the infant, the gap between the wet holding sheet and the infant's crotch is generally reduced. Is further increased, so that the intended purpose cannot often be achieved by the wet holding sheet.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view showing an embodiment of an article worn by an infant according to the present invention.

1 to 3 show a pants-type disposable article, that is, a disposable training pants. The pants are composed of a pants body 1 and a wetness detecting means 2. The pants body 1 is composed of a liquid-permeable inner sheet 3, a liquid-impermeable outer sheet 4, and a liquid-absorbent core 5 interposed therebetween. 8
And The inner and outer sheets 3, 4 extend outwardly from the outer periphery of the core 5 and define a leg peripheral concave curved edge 10 having a thigh abutment piece 9 forming the wetness detecting means 2 on both sides of the crotch region 8. I have. Between the longitudinally extending portions of the inner and outer sheets 3, 4, elastic elastic members 11 acting around the front and rear waist circumferences 6, 7 and the laterally extending inner and outer sheets 3, 4 extend. Elastic telescoping members 12 acting along the peripheral concave edge 10 of the leg are respectively mounted between them in the lengthwise direction. The pants body 1 is folded in two through the central portion of the crotch region 8 so that the inner sheet 3 is positioned inside the pants body 1, and is heat-sealed along both side edges 13 of the front and rear waist circumferential regions 6 and 7. Intermittently joined by means, the waist opening 14
And a pair of leg openings 15. In this state, the thigh contact piece 9 extends outward from the lower central portion of the leg opening 15. The thigh abutment piece 9 includes the inner and outer sheets 3, 4
And portions 3a, 4a, and 5a of the core 5 extend outward. Naturally, the outer peripheral edge of the thigh abutment piece 9 is joined by hot-melt bonding means or welding means like the outer peripheral edges of the inner and outer sheets 3 and 4 of the pants body 1. The thigh abutment piece 9 has a guiding means 16 as a compressed groove so that the base end thereof is easily bent downward.
The pants body 1 has a plurality of guiding means 17 as a plurality of squeezed grooves formed by the inner sheet 3 and the core 5 on the skin contact surfaces in the front and rear waist peripheral regions 6 and 7 and the crotch region 8. These guiding means 17 extend toward the thigh abutment piece 9 so that urination in the front and rear waist circumference areas 6 and 7 and the crotch area 8 is effectively transmitted to the thigh abutment piece 9.

In FIG. 4, the thigh abutment piece 9 a is formed of a sheet material having a liquid retaining property per unit area higher than that of the inner sheet 3, which is a horizontally long rectangle separate from the constituent members of the pants body 1. , Continuously crossing the crotch region 8 between the curved concave edges 10 of the two legs or between the lower central portions of the two leg openings 15.

The present invention is characterized in that the side edges of the front and rear waist regions 6 and 7 are formed in a continuous pants shape as shown in FIG. 1 and, for example, as shown in FIG. , 7 are not connected to each other, and are not limited to any of those embodiments.

The inner sheet 3 is made of, for example, a hydrophilic or hydrophobic fiber non-woven fabric, the outer sheet 4 is made of, for example, a plastic film or a laminate of this and a hydrophobic non-woven fabric, and the core 5 is made of, for example, fluff pulp. For example, a fiber nonwoven fabric, tissue paper, or plastic foam sheet having a higher hydrophilicity than the inner sheet 3 is used as the material for the thigh contact piece 9a.

[0013]

According to the infant wearing article according to the present invention,
Urination in the crotch region and the front and rear waist region is flow-transmitted to the thigh contact piece extending outward from both sides of the crotch region. Even if the worn article is displaced and the center part of the crotch area of the article is separated from the infant's inseam, the skin contact surface of the thigh contact piece contacts the skin inside the infant's thigh. Since the skin inside the thigh is more sensitive to wetting than the skin in the middle of the inseam, the infant can sense urination sharply by the moistening of the thigh abutment piece.

When the skin contact surface of the article body is provided with means for guiding urination to the thigh contact piece, the skin contact surface of the thigh contact piece is more effectively moistened, and the function of detecting wetness is provided. Can be further enhanced.
