Description

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 nighttime disposable diaper to be worn by an elderly person.

[0002]

2. Description of the Related Art Conventionally, disposable diapers have been products that mainly absorb effluents intended for babies, elderly people, etc. The ultimate goal is to continue to provide products that gently support people's minds and bodies, and continue to do their best to fulfill each person's dreams, that is, "to create kindness" and "to give kindness". And various products are being developed.

In this regard, there has been proposed a disposable diaper which can be used for an elderly person who cannot move the body, that is, for a "bedridden elderly person". When such a disposable diaper is used for an inactive "bedridden elderly person", it can be worn with less physical movement of the elderly than a pants-type disposable diaper worn through both legs. Pad-type disposable diapers that can be used are preferred.

It is also necessary to consider a case where such a disposable diaper is worn by a female hand. When used for light weight people such as babies,
Women can freely move and wear the baby's body, but when wearing it for elderly people who are as heavy as adults, it is difficult to move the body with the hands of women. For ", it is best to turn the body sideways. Therefore, in order to wear a disposable diaper with a female hand, the elderly person should be laid sideways, the disposable diaper described above should be laid, and the elderly person should lie on his back so that the buttocks etc. may be placed on the disposable diaper. Generally, a method of bending the disposable diaper from between the thighs and pulling out one end of the disposable diaper to the front of the body to attach the disposable diaper is generally adopted.

A thick disposable diaper used at night has also been proposed. This thick disposable diaper needs a water retention capacity of 400 g or more for night use, and to meet this condition, even if the latest technology is used, it is 5 mm.
A certain amount of thickness is required.

On the other hand, in Japanese Utility Model Publication No. 6-21622,
A disposable diaper has been proposed in which a disposable groove is formed on the body side of the disposable diaper so that it can be easily bent so that the clothing side is at the top, and wrinkles do not get around the inseam. You can get a feeling of wearing. Further, in such a disposable diaper, it is compressed in the width direction in the crotch region and deforms into a U-shape to form a cup-shaped space, so that the male genitalia can be wrapped therein.

[0007]

However, in such a disposable diaper, wrinkles do not occur in the crotch region,
Since a force is not applied in the width direction near the male genitalia, it is not easy to maintain the U-shape, and the male genitalia may not be fixed downward. For example, if the male genitals turn to the left and right, even if the disposable diaper adopts a three-dimensional gather, the male genitals may protrude outside the three-dimensional gather, and in that case, it is not possible to absorb body fluid. . Furthermore, when the male genitals face upward, the disposable diaper does not have its upper part closed, does not function as a leak-proof wall, and cannot absorb body fluid sufficiently by the absorbent body. , There is a risk that body fluid will leak to the outside of the disposable diaper.

[0008] Further, the "genital bedridden" male genitals have different shapes depending on the individual such as a dented male genital, an obliquely deformed male genital, etc. Among them, the short male genitals should be fixed downward. Is difficult, as mentioned above,
It is likely to be upwards and will not absorb all the body fluids of the "bedridden old man".

[0009] Furthermore, in order to prevent "bed sores" of "bedridden elderly people", it is necessary to carry out "position change" which is indispensable, and the "position change" may cause the male genitalia to face in a direction different from downward. There is a possibility that the male genitalia may stick out of the disposable diaper and not absorb body fluid.

On the other hand, in Japanese Patent Laid-Open No. 10-5274,
Disposable diapers have been proposed that have a pair of absorbers outside the three-dimensional gathers in the inseam area and enhance the fit in the inseam area, but do not reduce the absorbency in the inseam area. If the male genitalia protrudes from the three-dimensional gather, it cannot be dealt with.

Furthermore, with regard to such disposable diapers, since the positions of the genitals are greatly different between men and women, it is necessary to use both for men and women, and to purchase both. It is complicated. Also,
When a man wears a woman's wear, the possibility that a woman wears a men's wear may decrease the possibility of absorbing body fluid.

The present invention has been made in view of the above-mentioned problems, and fixes the male genitalia of the "bedridden old man" and sufficiently absorbs the body fluid of the "bedridden old man".
It is an object of the present invention to provide a disposable diaper capable of preventing liquid leakage.

Is drawn on the assumption that the bonding cloths 61 and 71 do not shrink due to the plurality of elastic members 62 to 64 and 72 to 74.
FIG. 3 illustrates only one side of the disposable liquid absorbent pad 10 according to the present embodiment, which is symmetrical.

As shown in FIG. 2, the disposable liquid-absorbing pad 10 has a liquid-permeable top sheet 31, a liquid-impermeable back sheet 41, and a liquid-absorbing property interposed between the top sheet 31 and the back sheet 41. The core 51 and the topsheet 31, the backsheet 41, and the liquid-absorbent core 51 are joined to each other, and a pair of joining cloths 61 and 71 extending in the longitudinal direction are formed.

The above-mentioned top sheet 31 comes into contact with the body side when worn, and is a liquid-permeable sheet such as a liquid-permeable nonwoven fabric or perforated plastic film, preferably a liquid-permeable and hydrophobic material. Sheets are used.

The above-mentioned back sheet 41, which comes into contact with the clothing side when worn, is a liquid-impervious plastic film or a laminated sheet of a plastic film and a hydrophobic nonwoven fabric, preferably a breathable liquid-impervious sheet. used.

The above-mentioned liquid-absorbent core 51 is a two-layer type liquid-absorbent core, and comprises an upper-layer liquid absorbent 101 and a lower-layer liquid absorbent 1.
31 and their upper layer absorbing liquid 101 and lower layer absorbing liquid 13
1, a liquid-permeable packaging sheet 121 covering the outer periphery of each of the
151 and. The absorbent core 51 in the present embodiment has the above-described configuration, but the present invention is not limited to this configuration, and for example, a high-absorption sheet or the like may be sandwiched, and further described below. As you
It may be a single-layer type absorbent core 201 (see FIG. 29).

FIG. 4 is a plan view and a sectional view showing the upper layer liquid absorbent 101 of the present embodiment, and FIG. 5 is a plan view and a sectional view of the lower layer liquid absorbent 131 of the present embodiment. Also,
FIG. 6 is a plan view showing the top sheet 31, and the dotted line shows the slits 103 to 106 provided in the upper layer liquid absorbent 101 located on the lower side thereof. The topsheet 31 shown in FIG. 6 is bonded with bonding cloths 61 and 71 with reference numerals 66 and 76 as boundaries. Further, FIG. 7 is a cross-sectional view showing the top sheet 31 and the bonding cloths 61 and 71 of this embodiment.

As shown in FIG. 4, the upper layer liquid absorbent 101 is a rectangular liquid absorbent with a semi-elliptical notch formed in the central side edge portion with respect to the longitudinal direction. The upper layer liquid absorbent 101 is a mixture of fluff pulp and superabsorbent polymer particles, is compressed to a required thickness, and is entirely covered with a water-permeable packaging sheet 121 such as tissue paper. The upper layer liquid absorbent 101 is formed so that its central portion is thicker than its both end edges in order to easily absorb the discharged matter.

The upper layer liquid absorbent 101 has two pairs of slits 1 extending in a V shape in each of the waist regions 20 and 21.
03 to 106 are provided. This slit 103-10
6 is formed in the same shape, and is formed symmetrically at the center of the disposable liquid-absorbing pad 10 formed in a vertically symmetrical manner and a horizontally symmetrical manner. Further, as will be described later, the slits 103 to 106 are substantially rectangular slits, and the side surfaces thereof are formed substantially perpendicular to the upper layer liquid absorbent 101.

In addition, the above-mentioned slits 103 to 106
Is 15 degrees or more and less than 90 degrees with respect to the longitudinal direction, and is preferably 30 degrees or more and 60 degrees or less. This is for the elastic members 62 and 72 and the slits 103 to 106 to intersect as shown in FIG. still,
In the present embodiment, the slits 103 to 106 have an angle of about 30 degrees with respect to the longitudinal direction of the disposable liquid absorbent pad 10, but as shown in FIG. 31, the angle of the disposable liquid absorbent pad 301 with respect to the longitudinal direction is about 80 degrees. Alternatively, as shown in FIG. 32, the angle of the disposable liquid absorbent pad 303 with respect to the longitudinal direction may be about 20 degrees.

As described above, since the disposable diaper "includes an elastic member that applies an elastic force in the longitudinal direction thereof, and the concave bent portion and the elastic member intersect each other",
It is easy to hold the bent state, and since the bent state is maintained after the bent habit, it is possible to easily and properly mount the cup shape without breaking it.

In addition, the above-mentioned upper layer liquid absorbent 101 has the main body region 108 and the slit 103 from the main body region 108.
And a region to be bent 109 divided by 106.

The slit 1 is formed in the bent region 109.
By performing a hinge press and an embossing press in parallel with 03 to 106, the rigidity in the direction parallel to the slits 103 to 106 is increased, that is, the bent region 109.
It is possible to make it easier to fold to the outside, and when it is attached, by preventing it from significantly protruding toward the body side, it becomes a disposable liquid absorbent pad that is even easier to attach.

In the disposable liquid absorbent pad 10 according to the present embodiment, the upper layer liquid absorbent 101 and the lower layer liquid absorbent 131 have substantially the same outer dimensions, but the present invention is not limited to this, and the upper layer liquid absorbent 101 or the lower layer liquid absorbent 131 is used. The shape of 131 may be substantially the same as that of the main body region.

This is because the function in the bent region 109 does not function as a liquid absorbent but a function as a leak preventive wall, so that it is not necessary to absorb body fluid so much. As a result, the accumulated liquid absorption can be replenished in the crotch region 22, and in this case, the function of further absorbing can be enhanced.

Furthermore, as described above, the bent region 10 is not formed without forming the hinge press and the embossing press.
Since it is possible to weaken the rigidity of 9 and make it easier to fold the bent region 109 to the outside, the disposable liquid-absorbing pad that is much easier to wear by preventing it from significantly protruding toward the body side when worn. Becomes

Furthermore, by making the bent region 109 thin, the rigidity of the bent region 109 is weakened, and it can be easily bent without forming the slits 103 to 106.

As shown in FIG. 5, the lower-layer liquid absorbent 131 has a rectangular liquid-absorbing liquid with a semi-elliptical notch formed in the central side edge portion with respect to the longitudinal direction, like the upper-layer liquid absorbent 101. It is a thing. In addition, this upper layer liquid absorbent 101
Is a mixture of fluff pulp and superabsorbent polymer particles, is compressed to a required thickness, and is entirely covered with a water-permeable packaging sheet 151 such as tissue paper.

6 is “b”, the distance between the slits 103 and 104 and the slits 105 and 106 is “c”, and the slits 103 to 1
The depth of 06 was designated as "d". Further, in the slits 136 and 137 in the present embodiment, the width thereof is “A”,
The length is “B”, the interval between the slit 136 and the slit 137 is “C”, and the depths of the slits 136 and 137 are “D”.

Hereinafter, FIGS. 4 and 5 and the symbols a to
The dimensions of the upper layer liquid absorbent 101 and the lower layer liquid absorbent 131 will be described using d and A to D.

In this embodiment, the depths d of the slits 103 to 106 of the upper layer liquid absorbent 101 are determined by the lower layer liquid absorbent 131.
The thickness is about the same as the thickness D and is about 3.5 mm. Furthermore, in this embodiment, the width a of the slits 103 to 106 is about 10.0 mm. Incidentally, the slit 103-
When the slit is formed with respect to the lower layer liquid absorption having a thickness of dmm, the width a of the slit is preferably 2d or more. For example, when a slit is formed for the lower layer liquid absorbent having a thickness of 5.0 mm, the width A of the slit is 10.0 mm.
The above is preferable.

On the other hand, in this embodiment, the slit 13
The width A of 6 is about 10.0 mm. Incidentally, the slit 13
When the slit is formed with respect to the lower layer liquid absorption having a thickness D mm, the width A of the slit is preferably 2D or more. For example,
When a slit is formed in the lower layer liquid absorbent having a thickness of 5.0 mm, the width A of the slit is preferably 10.0 mm or more.

Therefore, in the disposable diaper shown in FIG. 7 (A), when the slits 103 and 105 are bent so that the clothing side becomes the apex, as shown in FIG. 7 (B), the slit 103 is formed. , 105 are formed,
At the bent position, the body-side surfaces of the upper layer liquid absorbent 101 are not pressed against each other, and the rigidity can be weakened. Further, when the slit 136 is bent so that the body side becomes the apex, the slit 136 is formed as shown in FIG. 7C. The surfaces are not pressed against each other, and the rigidity can be weakened.

In the conventional disposable diaper as shown in FIG. 8 (A), since the upper layer liquid absorbent 91 and the lower layer liquid absorbent 81 are not provided with slits, as shown in FIG. 8 (B).
When folded so that the clothes side becomes the apex, the surfaces of the upper layer liquid absorbent 91 press against each other at the bending positions 92 and 93, thereby increasing the rigidity,
Further, as shown in FIG. 8 (C), when the body side is bent so as to have an apex, the bending position 82
Thus, the garment-side surfaces of the lower layer liquid absorbent 81 are pressed against each other to increase the rigidity.

Furthermore, in this embodiment, the length b in the longitudinal direction of the slits 103 to 106 is about 85 mm. The length b of the slits 103 to 106 in the longitudinal direction
Has a minimum thickness of 50 mm in the front-back direction,
It is preferable that 50 ≦ b ≦ (total length in the longitudinal direction of the upper layer liquid absorbent).

Further, in the present embodiment, the slit 10
Interval c between 3, 104 and slits 105, 106
Is about 230.0 mm. The distance c between these slits is preferably 50 ≦ c ≦ (the total length in the longitudinal direction of the upper layer liquid absorbent) because the thickness in the front-back direction of the body is at least 50 mm.

On the other hand, in this embodiment, the slit 13
The length B of 6 is about 150 mm. This slit 13
The length B of 6 is preferably 50 ≦ B ≦ (total length in the longitudinal direction of the lower layer liquid absorbent) because the thickness of the body in the front-back direction is at least 50 mm.

Further, in the present embodiment, the slit 13

m. Interval C between these slits 136 and 137
Has a minimum thickness of 50 mm in the front-back direction,
It is preferable that 50 ≦ C ≦ (total length in the longitudinal direction of the lower layer liquid absorbent).

Furthermore, the above-mentioned upper layer liquid absorbent 101 and lower layer liquid absorbent 131 both have a thickness of about 3.5 mm and a length of about 525 mm. Furthermore, the width of the upper layer liquid absorbent 101 is about 190 mm, and the width of the lower layer liquid absorbent 131 is about 220 mm. Therefore, the lower-layer absorbent liquid 131 far from the body side has a larger volume than the upper-layer absorbent liquid 101 closer to the body side.
It has a higher water retention capacity than 01, accumulates the absorbed exhaust farther from the body side, and prevents it from returning to the body side due to pressure.

Further, the amount of superabsorbent polymer particles differs between the upper layer liquid absorbent 101 and the lower layer liquid absorbent 131, and the amount of the lower layer liquid absorbent 131 includes a larger amount than that of the upper layer liquid absorbent 101. As a result, the water retention becomes higher than that of the upper layer liquid absorbent 101, and the absorbed discharge is accumulated farther from the body side, and is further prevented from returning to the body side due to pressure.

Further, the top sheet 31 is joined to the joining cloths 61 and 71 at boundary lines 66 and 76, as shown in FIG. 6 (A). Elastic members 62 and 72 are provided on the widthwise edges of the bonding cloths 61 and 71. Bonding cloth 6
1 and 71 are top sheets 3 as shown in FIG. 6 (B).
