BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disposable diaper, and more particularly to a disposable diaper composed of a diaper main body and an auxiliary absorbent pad formed smaller than the diaper main body.

[0002]

2. Description of the Related Art Conventionally, in order to increase the excretory liquid absorption capacity of diapers, etc., the disposable is composed mainly of a diaper and an auxiliary absorbent pad which is formed smaller than the diaper and is used as a main body of the diaper. Diapers are known.

[0003]

However, in the above-mentioned known diaper, since the holding means for the auxiliary absorbent pad mainly composed of the diaper is not reliable, the pad foolishly moves during use and is unpleasant for the wearer. Not only does it give a pleasant sensation, but it also has the drawback that the excretory fluid leaks into the pad without being absorbed properly.

An object of this invention is how to construct a means for surely holding the auxiliary absorbent pad in the diaper main body.

[0005]

As shown in the drawings, the present invention for solving the above-mentioned problems comprises a diaper main body 1 and an auxiliary absorbent pad 2 formed smaller than the diaper main body 1, and the diaper main body 1 Is a liquid-permeable upper sheet 3, a liquid-impermeable lower sheet 4, a liquid-absorbent core 5 interposed between the upper and lower sheets 3, 4, and extends outward from both side edges of the core 5. The liquid-impervious first flap 7 to which the elastic member 6 that extends and contracts in the vertical direction is branched, and the elastic member 8 that expands and contracts in the vertical direction branches off from the vicinity of both side edges of the core 5 and is separated from the branch edge. Assuming a disposable diaper with a second flap 9 attached to the free edge.

According to the present invention, on the premise, the release flaps 11 are provided on the inner surfaces of the second flaps 9, respectively, while the top sheet 3 facing each of the release guards 11 is provided.
The one of the upper surface of the first flap 7 Ru provided each adhesion portion 12 is covered with each of the releasing protective unit 11.

The auxiliary absorbent pad 2 is composed mainly of the diaper 1
When overlapped on the upper surface of the diaper, the widthwise both side portions are formed so as to be located at the respective adhesive portions 12 on the widthwise both side portions of the diaper body 1.

[0008]

In the diaper according to the present invention having the above-mentioned structure, both the second flaps 9 are lifted up and the two release protection portions 11 are peeled off from the both adhesive portions 12.
Both side portions of the auxiliary absorbent pad 2 are respectively interposed between and the lower surfaces thereof, and the lower surfaces of the both side portions are bonded to the bonding portion 12, respectively. By doing so, the auxiliary absorbent pad 2 can be overlapped and held on the upper surface of the diaper main body 1, but both second flaps 9 cooperate with their opposing surfaces to sandwich both side parts of the auxiliary absorbent pad 2. Therefore, the holding becomes more reliable.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the diaper according to the present invention will be described below with reference to the drawings.

As shown in FIGS. 1 and 2, the diaper according to the present invention comprises a diaper main body 1 and an auxiliary absorbent pad 2 formed smaller than the diaper main body 1. The diaper main body 1 includes a liquid-permeable upper sheet 3, a liquid-impermeable lower sheet 4, a liquid-absorbent core 5 interposed between the upper and lower sheets 3, 4, and both side edges of the core 5. Both sides of the core 5 and the liquid-impervious first flap 7 which is formed by a part of the upper and lower sheets 3 and 4 extending outward and is attached under extension with an elastic member 6 which expands and contracts in the vertical direction interposed. A second flap 9 is attached to the upper surface of the flap 7 near the edge, the elastic member 8 having one side edge joined thereto and extending in the longitudinal direction is wrapped with a free edge apart from the one side edge and attached under extension. A recessed portion 10 is formed along the circumference of the wearer's leg at the center outer edge of each of the first flaps 7. The core 5 is compressed on both sides so that the core 5 gradually becomes thinner toward the outer edge.

Both of the second flaps 9 are joined to the top sheet 3 by inclining both longitudinal ends of the second flaps 9 inwardly, and a mold release protection part 11 is provided on the inner surface near the front end part while the mold release protection part 1 is provided.
On the upper surface of the top sheet 3 facing the sheet 1, there is provided an adhesive portion 12 covered with a release protection portion 11. The mold release protection part 11 can be provided by applying silicon to the surface facing the adhesive part 12 or by bonding a tape having silicon applied to the facing surface to the surface. The adhesive section 12 can also be provided by applying an adhesive to the surface facing the release protection section 11 or by adhering a tape having the adhesive applied to the facing surface to the surface. The release protection part 11 and the adhesive part 12 can be provided at any position where the second flap 9 is located, but as shown in the drawing, at least the front end part and the facing part thereof must be provided respectively.

As shown in FIGS. 1, 3 and 4 , the auxiliary absorbent pad 2 has an outline shape which is generally smaller than the outline shape of the diaper main body 1, and moreover the pad is diaper main body 1.
When overlapped on the upper surface of the diaper, the widthwise both side portions of the pad are formed so as to be positioned at the respective adhesive portions 12 on both widthwise side portions of the diaper main body 1. The auxiliary absorbent pad 2 also includes a liquid-permeable upper sheet 13, a liquid-impermeable lower sheet 14, a liquid-absorbent core 15 interposed between the upper and lower sheets 13, 14, and both sides of the core 15. Flap 1 formed from a part of upper and lower sheets 13, 14 extending outward from the edges
6, and elastic members 17 that extend and contract in the vertical direction are attached to the inner surfaces of both side portions of the top sheet 13 while extending.
The core 15 is compressed so that the core 15 is gradually thinned toward its outer edges on both sides. The lower surface sheet 14 may have liquid permeability.

Nonwoven fabrics, porous plastic films and the like are used for the upper sheets 3 and 13, plastic films and the like are used for the lower sheets 4 and 14, and a mixture of crushed pulp and superabsorbent polymer particles is used for the cores 5 and 15. For the second flap 9, a breathable liquid-impermeable sheet or the like can be used.

The diaper having the above-mentioned structure is mainly a diaper 1.
Both the second flaps 9 of the
Both the release protection parts 11 are peeled off from both sides, the both side parts of the auxiliary absorbent pad 2 are interposed between the lower surfaces of the both flaps 9 and the upper surface sheet 3, and the lower surfaces of the both side parts are adhered to the both adhesive parts 12. As a result, the auxiliary absorbent pad 2 is held on the upper surface of the diaper main body 1.

[0015]

According to the diaper according to the present invention, since the holding means for the auxiliary absorbent pad mainly composed of the diaper is reliable, the pad does not move unintentionally during use and does not cause discomfort to the wearer. Moreover, the excreted liquid is normally absorbed by the pad, and it rarely leaks.
