Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disposable sanitary article such as a disposable diaper and a disposable sanitary article, and more particularly to a disposable sanitary article formed so as to reliably prevent lateral leakage of excrement.

[0002]

2. Description of the Related Art Conventionally, as an article of this type, for example, a liquid-absorbing material is loaded between a liquid-permeable top sheet and a liquid-impermeable back sheet, and both sides in the longitudinal direction are centered at the center. There is a case where a side flap is formed in a gather over a certain length and a side flap for preventing lateral leakage extends in the longitudinal direction and is provided upright at a position of the top sheet inside the gather (for example, Japanese Patent Laid-Open Publication No. No. 4-122256).

[0003]

However, in this type of disposable article, excrement is captured by side flaps formed upright on both sides of the liquid-absorbent material. If it falls down inside, it will be difficult to reliably capture the excrement. Therefore, this type of article is desirably formed so as to reliably prevent side leakage.

However, in the conventional product, the side flaps are merely formed in an upright shape. Therefore, when the conventional products are used, the side flaps are easily mounted in a state of being folded inward, and the side leakage preventing function is sufficiently provided. There was something I couldn't show.

[0005] The present invention has been proposed in view of such problems of conventional products.

Therefore, the technical problem of the present invention is that
An object of the present invention is to provide a disposable sanitary article formed so that side flaps can be prevented from falling inward and side leakage prevention performance is enhanced.

[0007]

The present invention employs the following technical means in order to solve the above-mentioned problems.

That is, the present invention, as shown in FIG.
The liquid-absorbent material 4 is loaded between the liquid-permeable top sheet 2 and the liquid-impermeable back sheet 3, and both sides 5 in the longitudinal direction are formed in the gathers 6 over a certain length centering on the center. A disposable sanitary article in which side flaps 7 for preventing lateral leakage extend in the longitudinal direction and are provided upright at positions of the top sheet 2 inside the gathers 6, wherein the side flaps 7 are disposed outside. And an outer surface at a substantially central position in the longitudinal direction is fixed to a surface position on both sides 5 in the longitudinal direction (claim 1).

The disposable hygiene articles of the present invention include disposable diapers and disposable sanitary articles. Here, the term “fixed” means to be fixedly attached, and is specifically realized by bonding with an adhesive or welding with heat.

In the present invention, the outer surface of the side flap 7 is fixed to the position of the top sheet 2 inside the gather 6, and the side flap 7 is opened outward, whereby the side flap 7 is tilted inward. It can be prevented from being mounted in a state where it is held.

Further, in the present invention, since the two parts are closely adhered to each other to form a laminated structure at the portion where the side flap 7 and the position of the topsheet 2 are fixed, the waterproofness at this portion is enhanced.

Further, in the present invention, it is preferable that the fixing portion of the side flap 7 is a lower portion of the outer surface.

This is because, in this case, it is possible not only to prevent the side flap 7 from being mounted in an inwardly folded state, but also to hold the rising function of the upper part of the side flap 7 without lowering the side leakage preventing function. .

In the present invention, it is preferable that a plurality of fixing portions 10 of the side flaps 7 are formed at intervals in the longitudinal direction of the side flaps 7 (claim 3).

This is because, in this case, the inward fall of the side flap 7 can be prevented more reliably than in the case where only one fixing portion 10 is provided.

Further, in the present invention, as shown in FIG. 4, the fixing portion 10 of the side flap 7 may extend in the longitudinal direction of the side flap 7 and be formed continuously over a predetermined length. Claim 4).

In this case, since the fixing portions 10 are continuous, it is possible to ensure that the side flaps 7 are erected in a state where the side flaps 7 are tilted outward. This is because it can be further prevented.

[0018]

Preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 shows a preferred embodiment in which the article of the present invention is realized in a disposable diaper 1. As shown in FIG.

In FIG. 1 and the like, reference numeral 2 denotes a liquid-permeable topsheet. The topsheet 2 is formed of, for example, a nonwoven fabric. Reference numeral 3 denotes a liquid-impermeable back sheet, and the back sheet 3 is formed of a synthetic resin film. Reference numeral 4 denotes a liquid-absorbing material. The liquid-absorbing material 4 is formed of, for example, an absorbent pad having a water-absorbing polymer. The liquid absorbing material 4 is smaller in size than the top sheet 2 and the back sheet 3 and is loaded between the top sheet 2 and the back sheet 3.

In the disposable diaper 1 of the present invention, both sides 5 in the longitudinal direction are formed in gathers 6 over a predetermined length centering on a central portion. The gather 6 is selected to have a length that fits the crotch when worn.

In the disposable diaper 1 of the present invention, a side flap 7 for preventing lateral leakage is provided in an upright position in the longitudinal direction at a position of the top sheet 2 inside the gather 6. The side flaps 7 are for surely preventing excrement from leaking from both sides of the diaper 1.

The side flap 7 includes a liquid-impervious band-like sheet 8 made of a synthetic resin film, and an elastic member 9a such as thread rubber passed through the open upper edge of the band-like sheet 8 in the longitudinal direction. Is provided. The band-shaped sheet 8
The diaper 1 is superimposed and adhered to both sides 5 in the longitudinal direction of the diaper 1, and an end 8 a at an inner position beyond a boundary 4 a with the liquid absorbent material 4 is adhered to the topsheet 2.

In the present invention, the outer surface of the side flap 7 at a substantially central position in the longitudinal direction is turned outward, and is fixed to the surface positions on both sides in the longitudinal direction with an adhesive. 10
Are fixed portions, and in this embodiment, two fixed portions 10 are formed at a lower portion of the outer surface of the side flap 7 at intervals in the longitudinal direction.

In the case of the present invention, the side flaps 7 are formed so as to rise outwardly at the central portion thereof by the fixing portions 10 and to be gradually inclined downward from the central portion toward the end 8a of the belt-shaped sheet 8.

Therefore, in the case of the present invention, since the side flaps 7 stand up in the state of being opened outward at the center, the upper part of the side flaps 7 stands up as shown in FIG. Therefore, according to this, it is possible to prevent the side flaps 7 from being mounted in a state of being folded inward, and the side flaps 7 can always exhibit the side leakage prevention function.

In the case of the present invention, since the side flaps 7 are fixed to both sides 5 in the longitudinal direction, the waterproof property at this location can be increased by the amount of the side flaps 7 being superposed.

As described above, in the case of the product of the present invention, the number of the fixing portions 10 is not limited to two, but may be three or more, or conversely, one.

The present invention may be formed as shown in FIG. That is, in the disposable diaper 1 according to the present invention of this embodiment, the fixing portions 10 are formed continuously in a longitudinal direction of the side flaps 7 over a predetermined length.

In the case of this embodiment, since the fixing portions 10 are continuous, the side flaps 7 can more reliably maintain the standing posture in a state where they are tilted outward. Therefore, according to this, it is possible to reliably prevent the lateral leakage of the excrement at the central portion of the side flap 7.

[0031]

As described above, in the case of the disposable hygiene article of the present invention, it is possible to prevent the side flap from being mounted in a folded state at the time of mounting. The leak prevention function can be sufficiently exhibited.

In the case of the present invention, since the side flaps and both sides in the longitudinal direction are fixed to each other, the waterproof property at this portion can be improved by the amount of the overlap of the side flaps.
