BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a urine absorbing pad for urinary incontinents who cannot control urination on their own initiative and bedridden elderly people who need nursing care.

[0002]

2. Description of the Related Art FIG. 10 is a front view showing a typical prior art urine absorption pad 1, and FIG. 11 is a sectional view taken along the line BB of FIG. The urine absorption pad 1 basically includes a first surface sheet 2 having water permeability, a pair of second surface sheets 3 having water permeability, a back sheet 4 having water impermeability, fluff pulp, and the like. 1 top sheet 2 and each 2nd top sheet 3 and back sheet 4
And a thread-shaped first linear body 6 having elastic elasticity.

The first topsheet 2 is provided on one side (upper side in FIG. 11) of the water absorbing layer 5 in the thickness direction (vertical direction in FIG. 11). The pair of second topsheets 3 are arranged in a width direction (FIG. 10) perpendicular to the longitudinal direction of the first topsheet 2 (vertical direction in FIG. 10).
And in the left-right direction in FIG. 11), and are provided so as to partially overlap on both sides, and extend in the same direction as the first topsheet 2.

The widthwise intermediate portions 3b of the respective second topsheets 3 are fixed to both widthwise side portions of the first topsheet 2, respectively. The back sheet 4 is provided on the other side in the thickness direction of the water-absorbing layer 5 so as to extend in the same direction as the first top sheet 2, and both sides in the width direction of the back sheet 4 are on one side in the width direction of each second top sheet 3. Fixed to the respective parts. Back sheet 4
Is the first in the widthwise middle portion 4a at both ends in the longitudinal direction.
It is fixed to both ends in the longitudinal direction of the topsheet 2, and the widthwise both sides 4 b of the both ends in the longitudinal direction are fixed to both ends in the longitudinal direction of each second topsheet 3. In this way, the water-absorbing layer 5 is covered by the first topsheet 2, each second topsheet 3, and the backsheet 4.

In addition, a plurality of first linear members are disposed between the one side portion in the width direction of each second top sheet 3 and the both end portions in the width direction of the back sheet 4 at the middle portion in the longitudinal direction of the urine absorption pad 1. Each of the bodies 6 is interposed. Each first linear body 6 has both ends 6a and 6b in the longitudinal direction sandwiched by the second top sheet 3 and the back sheet 4, and the middle section in the longitudinal direction is expanded and contracted by the second top sheet 3 and the back sheet 4. It is held freely. Each of the first linear bodies 6 is provided so that the urine absorption pad 1 is in an extended state in a state of being extended in a flat shape. When each of the first linear members 6 contracts, the urine absorbing pad 1
Is curved in such a manner that its middle portion in the longitudinal direction projects in the depth direction perpendicular to the paper surface of FIG. Note that the urine absorption pad 1 in FIG. 10 shows a state when it is extended in the longitudinal direction.

[0006] Such a urine absorption pad 1 is used, for example, mounted inside a pants 8 as shown in FIG. In a state before the water-absorbing layer 5 absorbs urine, both sides 1a in the width direction of the urine absorption pad 1 are in close contact with the skin 9a of the user 9 by the degenerating force of the first linear body 6 over the entire length in the longitudinal direction. . When the user 9 discharges urine, the urine passes through the first topsheet 2 or the second topsheet 3, is guided to the water absorbing layer 5, and is absorbed.

For example, if the water absorption layer 5 becomes heavy due to the absorption of urine, the widthwise side portions 1a of the urine absorption pad 1 separate from the skin 9a of the user 9, and the discharged urine is discharged. There is a possibility that the absorbent pad 1 leaks outward in the width direction. Even in such a case, in order to prevent the urine from leaking outward in the width direction of the urine absorption pad 1 (hereinafter, may be abbreviated as “lateral leakage prevention”), A pair of side flaps 10 are provided near both sides in the width direction.

Each of the side flaps 10 is attached to each of the second topsheets 3 fixed to both widthwise sides of the first topsheet 2.
A portion 3a extending from the intermediate portion 3b in the width direction to the other side portion extending inward in the width direction of the urine absorption pad 1, and each of the second linear bodies 7 having elastic elasticity. The other side portion in the width direction of each of the second topsheets 3 is folded back and fixed so as to overlap the widthwise middle portion of the portion 3a of the second topsheet 3. Each second linear body 7 is provided with the second surface sheet 3.
Are arranged so as to be interposed between the fold portions of the portion 3a of the second surface sheet 3, and both ends 7a and 7b in the longitudinal direction are respectively sandwiched by the portions 3a of the second surface sheet 3, and the intermediate portion in the longitudinal direction is a portion 3a of the second surface sheet 3. It is held so that it can expand and contract. Thus, each side flap 10 is formed.

When the water absorbing layer 5 absorbs urine and the widthwise side portions 1a of the urine absorption pad 1 are separated from the skin 9a of the user 9, the side flaps 10 are connected to the second lines as shown in FIG. Each side flap 10 is generated by the retraction force of the body 7.
The free end 10a in the width direction, in which the second linear body 7 is interposed, rises due to an increase in weight due to urine absorption of the water-absorbing layer 5 while remaining in close contact with the skin 9a of the user 9 over the entire length in the longitudinal direction, Thus, it is configured such that a gap is prevented from being formed between the skin 9a and the water absorbing layer 5, and the above-described lateral leakage of urination can be prevented.

[0010]

In the prior art as described above, if the width D of each side flap 10 is not selected to be sufficiently large, when the water absorbing layer 5 absorbs urine, the rise of each side flap 10 will occur. The height is insufficient, and the free end portion 10a of each side flap 10 does not adhere to the skin 9a of the user 9, so that the side leakage cannot be sufficiently prevented.

However, when the water-absorbing layer 5 does not absorb urine in the mounted state, the side flaps 10 fall down inward in the width direction of the urine absorbing pad 1 so as to overlap the first topsheet 2. Close contact with the user 9. Therefore, if the width D of each side flap 10 is formed large,
When urination is guided to the water absorbing layer 5, the side flaps 10 may hinder the urination. Further, the side flap 1 is provided so that urination is not hindered when the urine is guided to the water absorbing layer 5.
Also, when the width D of each side flap 10 is formed large, the free end portion 10 of each side flap 10 can be formed even when the side flap 10 is configured to fall down outward in the width direction of the urine absorption pad 1.
a extends outward in the width direction of the urine absorption pad 1 and becomes difficult to attach. As described above, it is not preferable to increase the width D of each side flap 10, and therefore, it is not possible to sufficiently prevent the lateral leakage as described above.

The free end portion 10 of each side flap 10
Even if a is in close contact with the skin 9a of the user 9, each of the side flaps 10 is formed of a water-permeable sheet. May leak out to the outside, and it may not be possible to sufficiently prevent lateral leakage of urination.

[0013] An object of the present invention is to provide a urination absorbing pad capable of reliably preventing lateral leakage of urination.

The urine absorption pad of the present invention is used, for example, attached to the inside of pants, and the water-permeable sheet of the second folded portion in which the linear body is interposed is in close contact with the user's skin over the entire length in the longitudinal direction, Prevent lateral leakage of urination. Furthermore, since the first and second folded portions are configured to be folded up, there is a problem as described in the prior art described above, that is, the movement of urination to the water absorbing layer in the falling state is hindered or obstructed when being worn. It does not become. Therefore, the rising height of the first and second folded portions can be increased, and lateral leakage of urination can be reliably prevented. Further, as described above, since the first and second folded portions are configured to include the water-impermeable sheet, even if a large amount of urine is discharged in a short period of time, the urine does not pass to the outside, and the discharged urine is absorbed by the water absorbing layer. Can be surely guided. Furthermore, in the urine absorption pad of the present invention, since the water-permeable sheet and the water-impermeable sheet can each be constituted by a single sheet,
The number of parts can be reduced as much as possible. Therefore, the material cost can be reduced, the manufacturing process can be simplified, the loss rate due to the occurrence of defective products can be reduced, and the production amount of the urination absorbing pad per unit time can be increased.

FIG. 4 is a perspective view of the urine absorbing pad 21, FIG. 5 is a cross-sectional view taken along the line VV of FIG. 4, and FIG. 6 is a cross-sectional view taken along the line VI-VI of FIG. FIG. 4 to 6 show a state in which the middle portion in the longitudinal direction of the urine absorption pad 21 is curved with the contraction of each linear body 27 described above. Further, the absorption layer 26 of the urine absorption pad 21 in FIG. 6 is simplified for ease of illustration.

When the linear members 27 are retracted, both ends in the longitudinal direction of the urine absorbing pad 21 are brought close to each other by the retracting force of the linear members 27, whereby the portion 26c of the water absorbing layer 26 at the intermediate portion in the longitudinal direction, and Part 26 of water absorption layer 26

Curve with 2c inside.

As described above, the shape of the urine absorbing pad 21 in a state where each linear body 27 is contracted and partially curved is the abdominal part 3 to be located on the abdominal side of the user, which is both ends in the longitudinal direction.
6 and a dorsal part 37 to be located on the dorsal side are substantially flat, and a crotch part 38 between the abdominal part 36 and the dorsal part 37, that is, a middle part in the longitudinal direction of the urine absorption pad 21.
But it is curved. The crotch portion 38 is a curved portion with the above-described portion 22c of the water-permeable sheet 22 inside.

When the urine absorbing pad 21 shifts from the extended state shown in FIGS. 1 to 3 to a curved state as shown in FIGS. 4 to 6, the first and second folded portions 28 and 29 are used.
Of the linear body 27 are the respective portions 33a, 3
3b, the portion 22c of the water-permeable sheet 22 suspended between
And spreads out on both sides in the width direction of the portion 22c of the water-permeable sheet 22 in a loose state. A pair of side flaps 39 for preventing lateral leakage of urination is respectively formed by the intermediate portions in the longitudinal direction of the first and second folded portions 28 and 29 developed in this manner. The crotch portion 38 is surrounded by the side flap 39 and the portion 22c of the water-permeable sheet 22 to form an accommodation space 42 that opens in the direction in which the side flap 39 is deployed (upward in FIGS. 5 and 6). .

In the curved state in which each linear body 27 is contracted, the size of the urine absorbing pad 21 is as shown in FIGS.
The length L3 of the intermediate portion in the longitudinal direction is smaller than that in the extended state shown in FIG. 1, and the length L3 'of the intermediate portion in the longitudinal direction after the contraction of each linear body 27 is about 75 to 150 mm. Also,
The rising height H1 of each side flap 39 is about 40 to 100 mm when it is maximized.

Referring to FIG. 6, fixing means 4 is provided on portion 23d of impermeable sheet 23 constituting abdominal portion 36.
6 are provided. The fixing means 46 is composed of a double-sided tape 47 and a protective tape 48 covering the double-sided tape 47. When the urine absorbing pad 21 is used, the protective tape 48 is peeled off from the double-sided tape 47, for example, on the inner surface of the pants,
The exposed surface facing the outside of the double-sided tape 47 is attached. In this way, the urine absorbing pad 21 is easily fixed to the pants. Therefore, it is possible to eliminate a problem that the urine absorption pad 21 is shifted from a correct mounting position due to, for example, movement of the user.

FIG. 7 is a longitudinal sectional view showing the mounted state of the urine absorbing pad 21. For convenience of explanation, the urine absorbing pad 21 is schematically shown. Urination absorption pad 2 of the present embodiment
1 is worn, the urination part of the user 43
The crotch portion 38 is positioned between the crotch of the user 43 such that the abdomen 36 is positioned on the abdomen of the user 43 so that the crotch 38 is exposed to the storage space 42 of the user 43. After that, the pants 44 are worn over the urine absorption pad 21. When the pants 44 are worn, the protective tape 48 is peeled off from the double-sided tape 47 as described above, and the double-sided tape 47 is attached to the inner surface 44a of the pants 44.

When the urine absorbing pad 21 is thus mounted inside the pants 44, the portions 22d and 22f of the water-permeable sheet 22 on the abdominal portion 36 and the back portion 37 are provided.
However, each comes into close contact with the skin 43a of the user 43. In addition, the side flaps 39 are deployed in a slack state, and the contraction force of each linear body 27 causes the portion 29 a of the water-permeable sheet 22 of the second folded portion 29 to adhere to the skin 43 a of the user 43.

FIG. 8 is a cross-sectional view showing a state of attachment of the urine absorbing pad 21 before the water absorbing layer 26 absorbs urine, and FIG. 9 is a urine absorbing pad 2 after the water absorbing layer 26 absorbs urine.
FIG. 2 is a cross-sectional view showing a mounting state of No. 1; Urination absorption pad 2
When the user 43 using 1 discharges urine, the urine passes through the permeable sheet 22 and is guided to the water absorbing layer 26.

When the water-absorbing layer 26 absorbs urine and is displaced by its weight in a direction away from the skin 43a of the user 43, the slack of each side flap 39 expands while being gradually extended, and the side flap 39 and the user The state in which the skin 43a is in close contact with the skin 43 is maintained.

As described above, in the urine absorbing pad 21 of the present embodiment, each side flap 39 is constituted by the first and second folded portions 28 and 29 which are provided by folding, as in the above-described prior art. Even when the rising height H1 is formed to be large as compared with a configuration in which the side flaps are folded down, the side flaps 39 prevent movement of urination to the water absorbing layer 26 or when the urination absorbing pad 21 is attached. The side flaps 39 do not get in the way. Therefore, it is possible to increase the rising height H1 of each side flap 39, thereby reliably preventing urine from leaking laterally. In addition, this makes it possible to form the accommodation space 42 large, and the effect of preventing lateral leakage is improved.

Further, in the prior art, the side flap for preventing lateral leakage is constituted by a water-permeable sheet, but the side flap 39 of the urine absorption pad 21 of the present embodiment is constituted by including the water-impermeable sheet 23. Therefore, even if there is a large amount of urination in a short time, urination can be surely guided to the water absorbing layer 26.

Further, in the prior art, as shown in FIGS. 10 to 12, the side flap and the sheet provided to cover one side in the thickness direction of the water absorbing layer are constituted by separate sheets having water permeability. However, since the urine absorption pad 21 of the present embodiment is constituted by only a single water-permeable sheet 22, the number of parts is reduced. Therefore, the number of sheet materials to be purchased by the manufacturer of the urine absorption pad 21 can be reduced, and the purchase cost can be reduced. Further, even in the case where a single sheet material is purchased and cut, the labor and cost for this are unnecessary, and the cost can be reduced. That is, the material cost can be reduced. In addition, the number of steps for bonding sheets to each other is reduced, and the linear body may be provided in a smaller number of places compared to the related art, so that the manufacturing process can be simplified. Therefore, the loss rate, that is, the rate at which defective products are generated, can be reduced, and the production amount of the urine absorption pad 21 per unit time can be improved. The present inventor has found that the material cost is 1 /
A reduction of about 10 has been confirmed. Also, since the number of parts is reduced, the processing loss such as the occurrence of defective products is reduced by 1 /
It has been confirmed that it decreases to 2 or less.

In the above-described embodiment, the second folded portion 29
Although the two linear members 27 are interposed between the water-permeable sheet portion 29a and the water-impermeable sheet 23 constituting the water-permeable sheet 23, the number of linear members is not limited to two. It may be one or three or more each. Further, the linear body 27 is not limited to the thread shape, and may be a band-like elastic elastic member such as a flat rubber string.

In the above-described water-permeable sheet 22, a nonwoven fabric having a feeling close to that of underwear is used because it is in direct contact with the skin 43a of the user 43. However, the present invention is not limited to a non-woven fabric, and may be a sheet having water permeability, and as another embodiment of the present invention, a woven fabric or a porous film may be used.

The water-impermeable sheet 23 is not limited to the above-mentioned polyethylene film, and may be a non-woven fabric having a strong water repellency, a composite material of a film and a non-woven fabric, or the like. It may be a composite of a film and a woven fabric.

Further, the urine absorbing pad 2 of the embodiment described above
1 is the length L1, L3, L4, and the width L described above.
The height is not particularly limited to 2, L5 and the height H1, and may be arbitrarily selected according to the size of the user 43 and the position and shape of the urination unit, such as for men, women and infants. Further, for each kind of urine absorption pad configured for various uses such as for men, women and infants, the water-impermeable sheet 23 is, for example, light blue for men,
By color-coding pink for women and white for infants, the purchaser can easily recognize the difference between the types.

The fluff pulp 24 of the water absorbing layer 26 may include fine particles obtained by concentrating sap containing components such as phytoncide, in addition to the water absorbing polymer 25. The fine particles, even in a dry state, generate a fragrance of a tree, and when dissolved by moisture such as urine, neutralize the main components of the odor, such as ammonia, and promote the evaporation of the fragrance of the tree. , The fragrance is increased, so that the water absorbing layer 26
Can increase the urinary absorption capacity of the urine, and further suppress the unpleasant odor such as the ammonia smell of urination, thereby generating the fragrance of the tree.

[0043]

According to the present invention, since the first and second folded portions are folded, the urinary movement to the water-absorbing layer in the downside state as described above, that is, the problem of the prior art described above, is prevented. There is no hindrance or hindrance during mounting. Therefore, the rising height of the first and second folded portions can be increased, and lateral leakage of urination can be reliably prevented.

Further, since the first and second folded portions include the water-impermeable sheet, even if a large amount of urine is discharged in a short time, the urine does not pass to the outside and the urine is discharged to the water absorbing layer. It can be surely guided.

Further, in the urine absorption pad of the present invention, since the water-permeable sheet and the water-impermeable sheet can each be constituted by a single sheet, the number of parts can be reduced as much as possible. Therefore, the material cost can be reduced, the manufacturing process can be simplified, the loss rate due to the occurrence of defective products can be reduced, and the output of the urine absorbing pad per unit time can be increased.

Further, according to the present invention, since a plurality of linear bodies are provided at intervals from each other, when the urine absorbing pad is used by the user, the user is allowed to provide the second folded portion with a wide area. Can be brought into close contact. Therefore, lateral leakage of urination can be more reliably prevented.

Claims (2)

[Claims] 1. A water-absorbing layer made of fluff pulp or the like is interposed between a water-permeable sheet and a water-impermeable sheet, and peripheral edges of the water-permeable sheet and the water-impermeable sheet are fixed to each other,
In the middle part in the longitudinal direction, on both sides in the width direction perpendicular to the longitudinal direction, a linear body having elasticity is sandwiched at both longitudinal ends of the linear body by the water-permeable sheet and the water-impermeable sheet. A urine absorbing pad provided in a state in which a degenerating force is applied, wherein a water-permeable sheet and a water-impermeable sheet are folded back on both sides in the width direction of the urine absorbing pad, and water is passed through both sides in the width direction of the water absorbing layer. Folded portion where the permeable sheet overlaps, and a second folded portion where the first folded portion is connected most inward in the width direction and the water-impermeable sheet overlaps outward in the width direction and the linear body is interposed. The first and second folded portions are fixed to both ends of the water-permeable sheet in which the water-absorbing layer is present at both ends in the width direction at both ends in the longitudinal direction. 2. The urine absorption pad according to claim 1, wherein a plurality of said linear bodies are provided at intervals from each other.
