Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a disposable diaper, and more particularly, to a disposable diaper including a diaper main body and an auxiliary absorbent pad formed to be smaller than the diaper main body.

[0002]

[Prior art]

 Conventionally, a disposable diaper including a diaper main body and an auxiliary absorbent pad formed to be smaller than the diaper main body and used for overlapping the main body of the diaper is known in order to increase the excretory fluid absorption capacity of the diaper. .

[0003]

[Problems to be solved by the device]

 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 unnecessarily moves during use, which not only gives the wearer a feeling of discomfort, but also the pad. In addition, there is a drawback that the excreted liquid leaks without being absorbed normally.

[0004] The present invention has an object of how to configure a means for surely holding the auxiliary absorbent pad in the diaper main body.

[0005]

[Means for Solving the Problems]

 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 top sheet 3 A liquid-impervious lower surface sheet 4, a liquid-absorbent core 5 interposed between the upper and lower surface sheets 3, 4, and an elastic member 6 that extends outward from both side edges of the core 5 and expands and contracts in the vertical direction. A liquid-impervious first flap 7 to which is attached and a second flap 9 to which an elastic member 8 which branches from the vicinity of both side edges of the core 5 and expands and contracts in the longitudinal direction is attached to a free edge apart from the branch edge. Assuming a disposable diaper with and.

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

When the auxiliary absorbent pad 2 is stacked on the upper surface of the diaper main body 1, both side portions in the width direction are formed so as to be positioned at the respective adhesive portions 12 on both side portions in the width direction of the diaper main body 1.

[0008]

[Action]

 In the diaper according to the present invention having the above-mentioned structure, both the second flaps 9 are lifted upward and the two release protection portions 11 are peeled off from both the adhesive portions 12, so that the space between the second flaps 9 and their lower surfaces is increased. The both sides of the auxiliary absorbent pad 2 are interposed between the two, and the lower surfaces of the both sides 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 hold both side parts of the auxiliary absorbent pad 2. Since it will be clamped, it will be held more reliably.

【Example】

 An embodiment of a 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 is composed of a liquid-permeable upper sheet 3, a liquid-impermeable lower sheet 4, a liquid-absorbent core 5 interposed between 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 to the outside and which is attached under extension with an elastic member 6 which expands and contracts in the vertical direction interposed. The flap 7 near the edge is provided with a second flap 9 in which one side edge is joined to the upper surface of the flap 7 and an elastic member 8 which expands and contracts in the longitudinal direction is wrapped with a free edge apart from the one side edge and attached under extension. . A concave cutout 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 of the core 5 so as to gradually become 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 11 is provided. On the upper surface of the upper surface sheet 3 facing the above, an adhesive portion 12 covered with a mold release protection portion 11 is provided. The release protection part 11 can be provided by applying silicon to the surface facing the adhesive part 12 or by adhering a tape having silicon applied to the facing surface to the surface. The adhesive portion 12 can also be provided by applying an adhesive to the surface facing the release protection portion 11 or by adhering a tape having the adhesive applied to the opposing 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 must be provided respectively. .

As shown in FIGS. 1, 3 and 4 , the auxiliary absorbent pad 2 has a contour shape which is generally smaller than that of the diaper main body 1, and the pad is placed on the upper surface of the diaper main body 1. When the pads are overlapped with each other, the widthwise both sides of the pad are formed so as to be located at the respective adhesive portions 12 on both widthwise sides 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. It is composed of flaps 16 formed from a part of upper and lower sheets 13 and 14 extending outward from the edges, and elastic members 17 which extend and contract in the longitudinal direction are attached to the inner surfaces of both sides of the upper sheet 13 under extension. There is. 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.

Non-woven fabric, porous plastic film, etc. for the top sheets 3, 13; plastic film, etc. for the bottom sheets 4, 14; mixture of crushed pulp and superabsorbent polymer particles for cores 5, 15 etc. For the second flap 9, a breathable liquid-impermeable sheet or the like can be used.

The diaper having the above-mentioned configuration lifts both second flaps 9 of the diaper main body 1 in the upward direction and peels off both release protection parts 11 from both adhesive parts 12, thereby removing the bottom surface and the top surface of both flaps 9. Both side portions of the auxiliary absorbent pad 2 are interposed between the auxiliary absorbent pad 2 and the toe 3, and the lower surfaces of the both side portions are adhered to the adhesive portions 12, whereby the auxiliary absorbent pad 2 is held on the upper surface of the diaper main body 1.

[0015]

[Effect of device]

 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 unnecessarily move during use and does not cause discomfort to the wearer. The excreted liquid is normally absorbed and the leakage is low.
