Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an infant wear article, and more particularly, a disposable article which is worn by an infant during a training period when he / she shifts to a life where he / she does not wear a diaper, and which is provided with a means for the infant to sense wetness due to urination. Regarding goods.

[0002]

2. Description of the Related Art Disposable so-called training pants having a wetness detecting means are conventionally known. For example, Japanese Utility Model Laid-Open No. 5-19305 discloses that a wet holding sheet is provided as a wetness detecting means on the skin contacting surface of the training pants, and Japanese Utility Model Laid-Open No. 7-33916 discloses that the skin contacting surface of the training pants. While fixing both ends of the stretchable wet holding sheet, the wet holding sheets between these both ends are temporarily joined with a water-soluble adhesive, and when contacted with urination, the wet holding sheet has the skin contact surface. Disclosed is a structure in which it is peeled off and lifted up and elastically pressed against the inseam of an infant.

[0003]

The known wetness sensing means can achieve the intended purpose to some extent as long as the wetness holding sheet is sufficiently in contact with the inseam of the infant. However, when the training pants are worn, the central part of the moisturizing holding sheet generally does not come into close contact with the infant's inseam. Is much larger, so that it is often not possible to achieve the intended purpose with the wet holding sheet.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of an infant wear article according to the present invention will be described below with reference to the drawings.

1 to 3, pants-type disposable articles, that is, disposable training pants are shown. 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, and front and rear waist regions 6, 7 and a crotch region therebetween. 8
Have and. The inner and outer surface sheets 3 and 4 extend outward from the outer periphery of the core 5 and define leg concave concave edges 10 having thigh abutment pieces 9 forming the wetness detecting means 2 on both sides of the crotch region 8. There is. Between the longitudinally extending portions of the inner and outer surface sheets 3 and 4, elastic elastic members 11 that act in the circumferential direction of the front and rear waist circumferential regions 6 and 7, and the laterally extending portions of the inner and outer surface sheets 3 and 4 are provided. Between them of the parts, elastic elastic members 12 acting along the leg peripheral concave edge 10 are respectively attached under extension in their longitudinal direction. The pants body 1 is folded in two through the center of the crotch region 8 so that the inner sheet 3 is located inside the pants body 1, and heat welded along both side edges 13 of the front and rear waist regions 6, 7. The waist opening 14 is intermittently joined by means.
And a pair of leg openings 15 are defined. In this state, the thigh abutment piece 9 extends outward from the lower central portion of the leg opening 15. The thigh contact pieces 9 are the inner and outer sheets 3, 4
The parts 3a, 4a, 5a of the core 5 are formed by extending outward. Of course, the outer peripheral edge of the thigh abutment piece 9 is joined by the hot melt adhesive means or the welding means in the same manner as the outer peripheral edges of the inner and outer surface sheets 3 and 4 of the pants body 1. The thigh abutment piece 9 has a guide means 16 as a compressed groove so that it can be easily bent downward at its base end.
The pants body 1 has guiding means 17 as a plurality of concave squeezing grooves formed by the inner surface sheet 3 and the core 5 on the skin contact surfaces in the front and rear waist regions 6, 7 and the crotch region 8. These guiding means 17 extend toward the thigh abutment piece 9 so that the urine in the front and back waist circumferential areas 6, 7 and the crotch area 8 can be effectively flow-transmitted to the thigh abutment piece 9.

In FIG. 4, the thigh abutment piece 9a is a horizontally long rectangle separate from the constituent members of the pants body 1 and is made of a sheet material having a higher liquid holding property per unit area than the inner sheet 3. The crotch region 8 is continuously crossed between the concave curved edges 10 on both legs or between the lower central portions of the leg openings 15.

The present invention, as shown in FIG. 1, is a pant type in which the side edges of the front and rear waist regions 6, 7 are continuous with each other, and, for example, as shown in FIG. , 7 in which the side edges are not connected to each other, but are not limited to any of those embodiments.

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

[0013]

According to the infant wear article of the present invention,
Urine urine in the crotch region and the front and back waist region is flow-transmitted to the thigh abutment pieces extending outward from both sides of the crotch region. Even if the worn article slips down and the center of the crotch region of the article separates from the infant's crotch, the skin contact surface of the thigh contact piece contacts the skin inside the thigh of the infant. Since the skin inside the thigh is more sensitive to wetting than the skin in the central part of the crotch, the infant can sensitively detect urination by wetting the thigh contact piece.

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