[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a front view of the disposable diaper 1 in a developed state, and FIG. 2 is an exploded perspective view of the disposable diaper 1. FIG. 1 is a view when each of the elastic yarns 5 and 6 described below is in an extended state. In actuality, a gather is formed on the disposable diaper 1 by contraction of each of the elastic yarns 5 and 6 and the three-dimensional Shrinks.

The disposable diaper 1 basically includes a cover portion 2 having a front abdomen 2A, a crotch portion 2C, and a back portion 2B, and a pair of covers provided on both sides of the back portion 2B of the cover portion 2. It is composed of a waistband band 3 (A, B) and an absorber 4 provided to extend from the crotch 2C on the skin side of the cover 2 to the front abdomen 2A and the back 2B. ing.

The cover portion 2 includes an outer liquid-impervious (non-woven cloth made of synthetic fiber or the like) sheet 2a made of a plastic film or the like that does not allow liquid to pass through, and a nonwoven cloth made of synthetic fiber with a good touch. And a liquid-permeable sheet 2b on the skin side. Then, after a plurality of leg gather elastic yarns 5 are intermittently adhered in a lengthwise direction around the two leg holes 2D of the crotch portion 2C of the liquid impermeable sheet 2a on the outer surface side, the liquid impermeable sheet on the outer surface side The liquid-permeable sheet 2b on the skin side is joined to the conductive sheet 2a by welding or adhesion. The skin-side liquid-permeable sheet 2b has a surface shape that becomes a loop-shaped female locking portion of a mechanical fastener as described later.

A plurality of waist gather elastic yarns 6 are arranged in the longitudinal direction on the upper part of the inner surface of the front abdomen 2A and the upper part of the inner surface of the back part 2B of the liquid-permeable sheet 2b on the skin side of the cover part 2 in the longitudinal direction. The strip-shaped sheets 8 intermittently bonded in the stretched state are joined by welding or bonding.

The elastic yarns 5 for leg gathers and the elastic yarns 6 for waist gathers are band-like or thread-like natural rubber or synthetic rubber, and the waist gathers and leg gathers are formed by the contraction force of the elastic yarns 5 and 6. Is naturally formed.

The pair of waist-stop bands 3 (A, B) are made of a knitted fabric or a nonwoven fabric made of synthetic fibers or the like having a surface shape that becomes a loop-shaped female locking portion of the mechanical fastener.

Here, the mechanical fastener is a pair of a hook-shaped male locking portion and a loop-shaped female locking portion, and when both are strongly pressed, the male locking portion and the female locking portion are mutually reciprocated. The male and female locking parts are released so that the male and female locking parts are released from the lock when the male and female locking parts are strongly pulled apart by hand. Also called. Note that a peelable adhesive may be used instead of the mechanical fastener.

Each of the pair of waist-stop band portions 3 (A, B) is formed in a triangular shape, and each base portion is formed on the back surface of the rear portion 2 B of the cover portion 2 (ie, the opaque portion on the outer surface side). It is joined to both sides of the liquid sheet 2a by welding or bonding so that the tops of the liquid sheets 2a project to both sides.

The inner surface of one of the waist-stop band portions 3A of the pair of waist-stop band portions 3 (A, B) is provided on the outer surface of the other waist-stop band portion 3B (the loop-shaped mechanical fastener). A hook-shaped first male locking member 7A of a mechanical fastener which is removably locked to the female locking portion) is attached.

As shown in detail in FIG. 3, the absorbent portion 4 is composed of a liquid-impervious back sheet 4a and a liquid-pervious top sheet 4b, and is made of a pulp fiber or a highly absorbent polymer liquid-permeable sheet. Absorber core 4c made of a mixture is wrapped and molded flat. Absorber portion 4 is formed in a trapezoidal shape such that the front abdomen side is slightly narrower and the rear back side is slightly wider. The cover part 2 is provided so as to extend from the crotch part 2C on the skin surface side to the front abdomen part 2A and the back part 2B. In addition, the absorber part 4 is not limited to a trapezoid. Further, a three-dimensional nonwoven fabric (cuff) for preventing lateral leakage of urine or the like may be provided on both sides of the upper surface of the top sheet 4b of the absorber portion 4.

The front surface of the absorber portion 4 on the front abdomen side and the back surface of the rear end portion on the back side are detachably attached to the skin surface of the cover member (loop-shaped female locking portion of the mechanical fastener). Hook-shaped second male locking members 7B of the mechanical fastener which are locked to the brackets are respectively attached. The second male locking member 7B can be attached to a location other than the above, for example, the crotch side of the absorber portion 4.

On both sides of the skin surface of the front abdomen 2A of the cover portion 2, detachable to the outer surfaces (loop-like female locking portions of the mechanical fastener) of the pair of hip stopper bands 3 (A, B). A hook-shaped third male locking member 7C of the mechanical fastener which is locked by itself is attached.

When the disposable diaper 1 configured as described above is worn on a wearer, as shown in FIG. 1, the disposable diaper 1 is expanded, and the absorbent portion is formed by the second male locking member 7B. 4, the front and rear back sides of the cover part 4 are respectively engaged with the front and rear back sides of the cover part 2, and as shown in FIG. 7 (b), the wearer 10 is turned upside down so that the rear part of the absorber 4 is applied to the rear part of the wearer 10 as shown in FIG. 7 (b). I do.

Thereafter, the second male locking member 7B on the front abdomen side of the absorber portion 4 is unlocked and turned upward at the crotch portion so that the front abdomen of the absorber portion 4 is in front of the wearer 10. Apply to the abdomen (see FIGS. 5 and 7 (c)).

Then, while applying the other detent band portion 3B to the outer surface of the front abdomen of the folded absorber portion 4, the one detent band portion 3A is applied to the outer surface of the other waist detent band portion 3B. Is locked by a third male locking member 7A (see FIGS. 6 and 7D).

Thereafter, the front abdomen 2A of the cover portion 2 is folded upward with the crotch portion 2C as a boundary, and a pair of waist-stopping band portions 3 (while covering the outer surface of the folded front portion of the absorber portion 4 ( A and B) is locked by a third male locking member 7C (see FIGS. 4 and 7 (e)). Thereby, wearing of the disposable diaper 1 is completed.

In the disposable diaper 1, after the front abdomen of the absorber portion 4 from which the second male locking member 7 B is unlocked is turned over and applied to the front abdomen of the wearer 10, Since the outer surface of the upper part of the front abdomen of No. 4 can be held by the waist-stop band portions 3 (A, B), the front abdomen of the absorber portion 4 is larger than the waist-stop band portions 3 (A, B). Since it is located inward, the front abdomen of the absorber portion 4 comes into direct contact with the front abdomen of the wearer 10, so that the fitting property is improved and leakage of urine and the like can be prevented.

Further, since the waist-stop band portions 3 (A, B) can press the upper part of the folded front portion of the absorber portion 4, the displacement of the absorber portion 4 can be prevented. Further, a waist gather is formed on the front abdomen 2A and the back 2B of the cover portion 2 by a waist gather elastic thread 6, and the leg gather elastic thread 5 surrounds the leg hole 2D of the crotch 2C. Since the leg gathers are formed, leakage of urine and the like can be prevented by each gather.

Further, since the second male locking member 7B of the absorber portion 4 and the first male locking member 7A of the waist stopper band portion 3 (A, B) do not directly contact the front abdomen of the wearer, Becomes better.

On the other hand, as shown in FIG. 7F, replacement of the absorber portion 4 is performed after the second male locking members 7 B are unlocked and the absorber portion 4 is separated from the cover portion 2. This can be easily performed by locking the new absorber portion 4 to the cover portion 2 with the second locking members 7B, so that the cover portion 2 can be used repeatedly.

It is needless to say that the disposable diaper 1 can be used as a conventional integrated type without separating the absorbent portion 4 and the cover portion 1.

[Effect of the invention]

 As is apparent from the above description, the present invention is characterized in that, after the front abdomen of the absorber part where the second locking member is unlocked is turned over and applied to the front abdomen part of the wearer, the absorption is performed. Since the pair of waist-stop bands can be locked by the first locking member on the outer surface of the front abdomen of the body part, the front abdomen of the absorber portion is located more inward than the pair of waist-stop bands. As a result, the front abdomen of the absorber portion directly hits the front abdomen of the wearer, thereby improving the fit and preventing leakage of urine and the like. Further, since the front abdomen of the folded-back absorber portion can be pressed by the pair of waist-stop bands, displacement of the absorber portion can be prevented.

Further, when replacing the absorber portion, the second lock member is unlocked to separate the absorber portion from the cover portion, and then the new absorber portion is locked to the cover portion by the second lock member. By doing so, the cover part can be used repeatedly.

In addition, the waist gathers are formed at the front abdomen and the back of the cover portion, and the leg gathers are formed around the leg holes of the crotch portion. 3) Leakage of urine and the like can be prevented by each gather.
