[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disposable diaper, and more particularly, to a structure for detachably attaching front and rear bodies of the diaper.

[0002]

2. Description of the Related Art It is well known that as a means of wearing disposable diapers, the front and rear bodies are overlapped at the waist side, and both bodies are detachably fastened with a fastener tape extending outward from the waist side edges. It is. As one type of this fastener tape, for example, a disposable diaper using a combination of a barbed tape known as a trade name Velcro tape and a detachable adhesive tape is disclosed in Japanese Patent Application Laid-Open No. 48-30.
No. 547.

[0003]

A diaper provided with a fastener tape can adjust the tightening strength around the belly and the waist when worn by the tape. In particular, when the diaper is made to have elasticity in the direction around the belly or the waist, the adjustment is easy. However, the fastener tape of the disposable diaper is generally made of a non-stretchable material without being limited to the above-mentioned known technology, so if the diaper does not have elasticity in the belly or waist direction, if the tightening is too strong. There is a problem that the wearer becomes suffocated.

In view of the above, the present invention has an object to solve the above-mentioned problems of the prior art by forming the fastener tape with a hooked fastening member and an elastic fastening member.

[0005]

Means for Solving the Problems Diapers according to the invention
Is at least a water-permeable topsheet and a water-impermeable backsheet
The front and back body is attached to and detached from the waist side
Means for fastening freely, said means being
A sheet-like hooked fastening member provided on the back sheet side of the time,
Of the fastening member extending outward from the waist circumference side edge of the back body
Such as a sheet-like elastic fastening member having an engagement portion with a hook
In the disposable diaper comprising
That it consists of a number of longitudinally long slits
Features.

[0006]

[Function] In this invention, a fastening member made of an elastic sheet is used to fasten the diaper's front body and back view, so when wearing it, the distance between the front body and the back view will expand and contract under elastic action. Then, the slit expands and the hook engages with the slit.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the illustrated embodiment.

FIGS. 1 and 2 show a disposable diaper 1 according to the present invention. FIG. 1 is a perspective view showing a worn state.
FIG. 2 is an exploded plan view showing a part of the structure. The diaper 1 is composed of a water-permeable top sheet 2, a water-impermeable back sheet 3, an absorber 4 interposed between the two sheets 2 and 3, and provided on the back sheet 3 near both side edges of the front body 6. A pair of hooked fastening members 8 and a pair of elastic fastening members 9 provided to extend outward from both side edges of the rear view 7.
And a pair of leg elastic members 10 extending in the longitudinal direction of the diaper 1 between the side edges and the absorber 4. In such a diaper 1, a hooked fastening member 8 and an elastic fastening member 9 are provided.
Are detachable from each other, and the diaper 1 worn as shown in FIG. 1 fits around the abdomen and the waist by fastening these two members 8 and 9, and can be taken off freely.

FIG. 3 is a view taken along the line XX of FIG.
The hooked fastening member 8 is schematically shown. The fastening member 8 is made of a synthetic resin, and a base material 13 having a circular or elliptical flat surface, a hemispherical side surface (cross-section), and a hook 12 having a smooth surface is formed on the back sheet 3 by hot-melt adhesive, sewing, or the like. Are joined by appropriate means.

FIG. 4 is an enlarged plan view of the elastic fastening member 9, in which sheets of urethane rubber or various elastomers are provided with a number of slits 14 as engaging portions . Each slip
When a large number of gates 14 are arranged in the length direction of the elastic fastening member 9,
Both are arranged so that they are alternately positioned in each column.
is there. When the diaper 1 is worn and the fastening member 9 is pulled in the abdomen direction, the slits 14 are widened and the hooks 12 of the hooked fastening member 8 can be extremely easily attached. The fastening member 9 is sandwiched between the top sheet 2 and the back sheet 3, but can be joined to either sheet surface. As means for the holding and joining, there are means such as bonding and stitching by hot melt.

When the diaper 1 constructed as described above is worn, even if the diaper 1 does not have an elastic member around the belly or the waist, the gap between the front and rear bodies elastically expands and contracts. There is no suffocation around the waist or around the waist.

FIG. 5 shows a case in which one long elastic fastening member 9 is attached to the inside of the edge of the rear view 7 under extension and serves also as a waist elastic member in the diaper 1. By doing so, the entire waist circumference is stretched, so that the fit to the wearer is extremely good.

As for the diaper 1, in addition to the above-mentioned structure and materials used, known or well-known techniques can be used as appropriate.

[0014]

[Effects of the Invention] In the diaper according to the present invention, when the elastic fastening member is stretched against its elasticity during its use,
Each slit is expanded and easily engages with each hook of the hooked fastening member, and when it is extended and released, each slit closes due to contraction of the elastic fastening member to strongly clamp each hook. Is securely held. In addition, since the elastic fastening members need only be provided with slits, their manufacture is extremely easy.
