BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disposable diaper, and more particularly, to a disposable diaper for using a separate absorbent pad on the inside.

[0002]

2. Description of the Related Art Conventionally, for example, in a disposable diaper for an adult or a bedridden elderly, a separately prepared liquid-absorbent pad is used by simply superimposing the pad on the inside from the viewpoint of the absorption capacity of excreted liquid and economy. Things are known. In such a diaper, as long as the outer diaper that covers and holds the absorbent pad is not damaged or soiled, only the absorbent pad can be replaced and the outer diaper can be used a plurality of times.

[0003]

The outer diaper has a liquid-absorbent core, unlike a generally-known diaper cover. If an absorbent pad is further superimposed on the inside of such an outer diaper, not only will the entire diaper be bulky and unsightly, but it will also interfere with the wearing of underwear, and the absorbent pad will be deviated from the outer diaper. There are a number of drawbacks, such as slippage, and the inability of the stretchable elastic members arranged on both sides of the crotch region of the outer diaper to make both sides sufficiently adhere to the wearer's thigh, thereby causing excretion to leak.

[0004] This invention eliminates the bulk of the diaper,
An object of the present invention is to configure an exterior diaper so that a liquid-absorbent pad is stably superimposed on the inside of the exterior diaper and both sides of a crotch region of the exterior diaper are adhered to a thigh.

[0005]

Means for solving the above-mentioned problem according to the present invention is that a liquid-permeable inner sheet and a liquid-impermeable outer sheet have a first liquid absorbing property between both sides thereof. The core is interposed so as to extend from both side edges of the core, and concave notches for thighs are formed on both sides of the inner and outer sheets, and a first elastic member is attached along the concave notches. A second sleeve is provided on both sides of the inner sheet in the lengthwise direction of the diaper.
A disposable diaper having an inner edge of a flap formed with an absorbent core interposed therebetween and a second elastic member attached to an outer edge of the flap.

The present invention is based on the premise that the first expansion / contraction elastic member is provided between the opposing first elastic members.
A concave area is formed in the liquid-absorbent core, and the joint portion of the flap to the inner sheet is located near the first elastic member.

[0007] In a preferred embodiment, the recessed region does not have the liquid-absorbent core interposed in the region, or the thickness of the liquid-absorbent core in this region is different from that of the first liquid-absorbent core in another region. The thickness of the inner sheet is smaller than the thickness of the inner sheet, the flaps are tilted outward, and both sides in the longitudinal direction are joined to the upper surface of the inner sheet, and the inner sheet portion of the recessed area Includes that the elastic elastic holding sheet is joined at both ends in the same direction while extending in the length direction thereof.

[0008]

The diaper according to the present invention having the above structure is used as the above-mentioned armored diaper, wherein the recessed region of the liquid-absorbent core is located between the opposing first elastic members. ing. Therefore, the rigidity of the recessed region is lower than the rigidity of the diaper component in the front and rear regions, and the recessed region contracts relatively easily due to the contraction force of the first elastic member, in other words, the first elastic member. That the contraction force is restricted by the rigidity of the recessed area, compared to the case where the recessed area is not formed and there is the same amount of liquid-absorbing material per unit area as the other area of the liquid-absorbing core. , Considerably less. Also, the first elastic member contracts the flap in cooperation with the second elastic member.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIGS. 1 to 4, in a diaper, both sides of a liquid-permeable inner sheet 1 and a liquid-impermeable outer sheet 2 have a first liquid-absorbing core 3 therebetween. The core 3 is interposed so as to extend from both side edges of the inner and outer sheets 1 and 2.
A concave notch 4 having a shape suitable for surrounding the thigh is formed on both sides of the sheet, and a plurality of thread-like elastic elastic members 5 are stretched along the concave notch 4 between the inner and outer sheets 1 and 2 at a required magnification. It is arranged below and attached with adhesive. Also, a plurality of thread-like elastic members 6 are arranged between the inner and outer sheets 1 and 2 in the back-side waist-encircling portion under the required magnification and attached with an adhesive.

On both sides of the inner sheet 1, a long sleeve 9 is formed in the longitudinal direction from the liquid-permeable inner strap 7 and the liquid-impermeable outer strap 8, and the inside of the sleeve 9 is removed except for both ends in the length direction of the sleeve 9. A flap 11 is formed with an absorbent core 10 interposed therebetween. The flap 11 joins the inner edge of the sleeve 9 to the upper surface of the inner sheet 1 along a stretchable elastic member 5 by a joining means such as an adhesive or fusion bonding. A plurality of thread-like elastic members 12 are arranged along the inside of the edge under the required magnification and attached with an adhesive (not shown).
To the outside, and the both ends 13 in the longitudinal direction thereof are attached to the inner sheet 1.
It is joined to the upper surface of.

A recessed area 14 is formed in the liquid-absorbent core 3 between the two opposing elastic members 5. Depressed area 14
Is formed by not interposing the liquid-absorbent core 3 in the illustrated example, but the thickness of the liquid-absorbent core 3 there is to be smaller than the thickness of the liquid-absorbent core 3 in other regions. May be formed. In short, the rigidity of the recessed area 14 is lower than the rigidity of the diaper component in the front and rear areas, and the recessed area 14 contracts relatively easily due to the contraction force of the elastic elastic member 5, in other words, the elastic elastic member 5 The fact that the contraction force is restricted by the rigidity of the recessed area 14 is compared with the case where the recessed area 14 is not formed and the amount of the liquid-absorbing material per unit area is the same as the other area of the liquid-absorbent core 3. do it,
When the liquid absorbing pad (not shown) prepared separately is superimposed on the recessed area 14, it is sufficient that the pad has a depth that holds the pad with good stability. Depressed area 1
Numeral 4 is biased toward the front waist-encircling portion so as to occupy at least the region receiving the most excreted liquid during excretion.

On the upper surface of the inner sheet 1 in the recessed area 14, a holding sheet 15 having elasticity at least in the length direction of the diaper is extended under the length direction in the length direction. Joined by joining means.

Tape fasteners 16 are attached to both side edges of the back waist portion for adhesively fixing both sides to the outer surface of the front waist portion when the diaper is worn.

The components of the diaper include materials known as those of this type of diaper, for example, a fibrous nonwoven fabric / porous plastic film on the inner sheet 1 and the inner strap 7, and a repellent material on the outer sheet 2 and the outer strap 8. Water treated fibrous non-woven fabric / plastic film, fluff pulp, mixed with superabsorbent polymer particles for cores 3, 10 and natural or synthetic material having rubber elasticity for stretchable elastic members 5, 12 respectively can do.

[0015]

According to the diaper according to the present invention having the above-described structure, the diaper has the function as described in the above-mentioned section of the function. The two sides of the liquid-absorbent pad can be held in close contact with the wearer's crotch, and the flap is placed around the wearer's thigh by cooperative shrinkage of the first elastic member and the second elastic member. Can be in close contact. Therefore, leakage of excrement from the thigh circumference can be prevented as much as possible.

Since the elastic sheet is joined to the inner sheet portion of the recessed area, the liquid absorbing pad is more securely held in combination with the presence of the recessed area, and the pad is prevented from shifting. Can be.

[0017] Due to the presence of the recessed area, even when the liquid-absorbent pad is superimposed thereon, the entire diaper does not become bulky and unsightly, nor does it hinder the wearing of underwear.
