Abstract

PROBLEM TO BE SOLVED: To prevent a penis from slipping out of an opening part due to the movement of a urine collecting pad caused by force applied to the urine collecting pad by the movement of a wearing person. SOLUTION: A bag body 1 is formed of a laminated body 10 comprising an inner surface sheet, an outer surface sheet and an absorbing core. The bag body 1 is provided with an opening part 20. In an area 31 provided to surround the opening part 20, the rigidity of the laminated body is lower than that of the other part of the laminated body. Since the low rigidity area 31 is provided, force applied to a urine collecting pad is not directly transmitted to the opening part so as to restrain a penis from coming off the opening part 20.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bag-shaped urine absorbing pad used for urinary incontinence and the like. The present invention relates to a urine absorbing pad that is less likely to generate water.

[0002]

2. Description of the Related Art A urine absorbing pad used for urinary incontinence or the like is a laminate comprising a liquid-permeable inner sheet, a liquid-impermeable outer sheet, and a liquid absorber sandwiched between the two sheets. Is formed. The liquid absorber is formed of a water-absorbing fiber such as pulp, or a mixture of the absorbent fiber and a superabsorbent polymer (SAP).

[0003] As the urine absorbing pad, there is a pad in which a bag is formed from the laminate and an opening is formed in the bag.
The urine absorbing pad of this structure is mainly used for men,
A penis is inserted into the bag through the opening, and urine discharged into the bag is absorbed by the liquid absorber.

[0004]

In the conventional urine absorption pad, the rigidity of the laminated body constituting the bag body is uniform, and the laminated body also exists around the opening. Therefore, the rigidity of the laminate at the periphery of the opening and the rigidity of the laminate at a region apart from the opening are substantially the same.

Therefore, when the urine absorbing pad moves with the penis inserted through the opening, the laminate in the region around the opening cannot be flexibly deformed, and the penis tends to come off from the opening. . For example, after attaching the urine absorbing pad to the penis, when attaching the diaper to the outside of the urine absorbing pad, the urine absorbing pad is shifted in the diaper by the external force of the attachment, or the urine absorbing pad and the diaper are attached. In the state, when you roll over and move your body,
The urine absorbing pad is displaced, so that the penis comes off from the opening and urine easily leaks out of the urine absorbing pad.

In the conventional urine absorbing pad, when the diaper is worn from the outside, the bag is bent or broken by the tightening force of the diaper, and as a result, the bag formed of a laminate is formed. The internal space of the space may become narrow, and it may not be possible to secure sufficient water retention capacity.

The present invention solves the above-mentioned conventional problems, and the urine does not come off from the opening even when the urine absorbing pad is subjected to an external force, that is, when the diaper is worn or the urine absorbing pad is worn. It is an object of the present invention to provide a urine absorbing pad capable of stabilizing a mounted state even when a body position of a human body changes in a state.

Another object of the present invention is to provide a urine absorbing pad which can prevent the bag from being bent or broken, thereby preventing a substantial reduction in the volume of the internal space of the bag.

[0009]

According to a first aspect of the present invention, there is provided a laminate having a liquid-permeable inner sheet, an outer sheet, and a liquid absorber sandwiched between the two sheets so that the inner sheet faces inward. In a urine absorbing pad in which a bag is formed and the bag is provided with an opening, the bag has a rigidity of the laminate in a region surrounding the opening, which is higher than a rigidity of the laminate other than the region. Is also low.

According to the present invention, the bag formed of the laminated body including the inner sheet, the outer sheet, and the liquid absorber is displaced due to an external force when the diaper is mounted on the outside of the bag, a change in the body position when the diaper is mounted, and the like. Even so, since the rigidity of the laminate around the opening is low, external force acting on the bag is absorbed by deformation of the low-rigidity laminate near the opening holding the urinary organ. Therefore, the urinary organ is less likely to come off the opening. In addition, since the rigidity of the bag body is high except around the opening, the bag body is unlikely to bend or break due to an external force when the diaper is worn, and the water retention capacity of the internal space of the bag body can be increased. In the present invention, since a laminate is present around the opening although the rigidity is low, the liquid absorbing layer of the laminate can exhibit a liquid absorbing function also around the opening.

In the present invention, the structure for lowering the rigidity of the laminated body in the region surrounding the opening than in other regions may include a thickness of the liquid absorber in the region surrounding the opening. The thickness is smaller than the thickness of the liquid absorber other than the region. The density of the liquid absorber in a region surrounding the opening is lower than the density of the liquid absorber in a region other than the region. Is preferred.

Further, at the boundary between the low-rigidity area surrounding the opening and the other high-rigidity area in the urine absorbing pad, a deformed boundary portion where the liquid absorber is thinned or the liquid absorber is removed is formed. Preferably, it is formed. By forming the easily deformable boundary portion in this way, the laminate in the region surrounding the opening, that is, the laminate inside (the opening side) than the deformed boundary portion, is easily deformed, and the urology becomes difficult to open. It is hard to come off.

Next, a second aspect of the present invention is to provide a laminated body having a liquid-permeable inner sheet, an outer sheet, and a liquid absorber sandwiched between the two sheets to form a bag body in which the inner sheet faces inward. In the urine absorbing pad provided with an opening in the bag, the liquid absorber may be thinned or the liquid absorber may be provided at the boundary between the region surrounding the opening and the other region. Characterized in that a deformed boundary portion from which is removed is formed.

According to the second aspect of the present invention, the deformed boundary portion where the liquid absorber is thinned or the liquid absorber is removed is provided at the boundary between the region surrounding the opening and the other region at a distance from the opening. Is formed, the laminate in the region around the opening is easily deformed independently of other regions of the bag. Therefore, even if an external force acts on the urine absorbing pad, the urinary organ does not easily come off the opening.

[0015] In the opening of the urine absorbing pad of the present invention,
It is preferable that a fastening means for fastening the opening to the penis inserted into the bag is provided.

In the urine absorbing pad of the present invention, it is preferable that an elastic sheet is provided in the bag body and in a region other than a region surrounding the opening. When the elastic sheet is provided, the bag is less likely to bend or break due to external force, and a large water holding space in the bag can be always secured. In addition, when the said elastic sheet is provided in the inner surface side of the said bag, it is preferable that the said elastic sheet is liquid-permeable.

[0017]

The bag 1 is composed of a laminate 10. As shown in the sectional views of FIG. 5 and FIG.
Is composed of an inner sheet 11, an outer sheet 12, and an absorbent core (liquid absorber) 13 interposed between the two sheets. The inner sheet 11 is a liquid-permeable sheet, and is, for example, a nonwoven fabric such as a point bond, an air through, a spun bond, or a spun lace formed of hydrophilic fibers or hydrophilic fibers. Among them, an air-through nonwoven fabric having a basis weight of 20 to 30 g / m ² is preferable.

The outer sheet 12 is liquid-impermeable, and is formed of, for example, an olefin-based resin sheet. Preferably, the basis weight is 20 to 30 g / m ² and the thickness is 20 to 30 μm.
Is a polyethylene sheet. Alternatively, the outer sheet 12 may be a transparent or translucent polyethylene film with a point-bonded nonwoven fabric laminated on the outer surface. When the outer sheet 12 is used, when the absorbent core 13 absorbs a large amount of urine and changes its color, it can be visually confirmed from the outside. Further, an adhesive layer for preventing slippage from the diaper may be provided on the surface of the back side 5 shown in FIG. In addition,
The outer sheet may be liquid permeable. In this case, the urine that has not been completely absorbed by the absorbent core 13 passes through the outer sheet 12 and is absorbed by, for example, a diaper applied to the outside.

The absorbent core 13 is formed of pulverized pulp or a mixture of pulverized pulp and superabsorbent polymer (SAP), and is wrapped with an absorbent sheet such as a tissue. The specific mixing ratio of pulp and SAP is preferably pulp: SAP = about 70:30 to 50:50. Alternatively, the absorbent core 13 is composed of a nonwoven fabric formed of hydrophilic fibers and SAP, and the SA
P may be interposed between the nonwoven fabrics, and the nonwoven fabrics may be partially joined.

FIG. 8 shows the laminate 10 constituting the bag 1.
Is shown in an unfolded state, but the laminate 10 in the unfolded state is shown.
Is a flat sheet, and each edge 14, 15, 16, 1
7, the inner sheet 11 and the outer sheet 12 extend outside the absorbent core 13 without the absorption core 13, and the two sheets 11 and 12 are joined by bonding or heat sealing or bonding and heat sealing. Have been.

In the unfolded state shown in FIG. 8, the upper edge 14
And the lower edge 15 are parallel, both sides in the horizontal direction, and the upper edges 17, 17 are parallel to each other, and the edges 16 and 1 on both sides in the horizontal direction.
Reference numeral 6 denotes inclined edges that approach each other on the lower end side. With the bag 1 formed, an opening 20 as shown in FIG.

The laminate 10 has a boundary 30 surrounding the edges 17. Here, a part of the laminate 10 surrounding the opening 20 inside the boundary 30 (opening side) is a region 31, and the other part, that is, a region 32 outside the boundary 30 is the region 32 of the laminate 10. .

As shown in FIG. 8 and FIG.
In 1, the absorption core 13 is formed thinner than the region 32, and the rigidity of the laminated body 10 is lower in the region 31 than in the region 32. Alternatively, the absorption core 13 is formed in the region 31 and the region 32.
Are the same, the density of the absorbent core 13 in the region 31 is lower than the density of the absorbent core 13 in the region 32, and as a result, the rigidity of the laminate 10 in the region 31 is lower than that in the region 32. Good.

Alternatively, in the region 32, the absorbent core 1
When the SAP in 3 is given water and the SAP and the fiber forming the absorbent core are bonded, or the SAP and the outer sheet 12 are bonded, the rigidity of the laminate 10 in the region 32 is reduced. It may be formed higher than 31. Further, the basis weight of the absorbent core 13 may be the same in the regions 31 and 32, and embossing or heat embossing may be formed in the region 31 in a dot shape to make the laminate of the region 31 flexible.

Further, at the boundary portion 30 separating the regions 31 and 32 having different rigidities, a concave portion may be formed in the absorbent core 13 to facilitate the deformation of the region 31. In this case, the concave portion can be formed by reducing the thickness of the absorbing core 13 at the boundary portion 30, removing the absorbing core at the boundary portion 30, or performing a heat embossing process on the absorbing core 13.

The laminate 10 in the high rigidity region 32
Is about 15 to 18 g · cm by the taper measurement method, and the rigidity of the laminate 10 in the region 31 is preferably lower than the above range.

The edges 17, 17 have elastic members 18, which constitute fastening means (holding means) for the penis,
18 are adhesively fixed. The elastic member 18,
18 gives a soft touch to the skin,
It is preferable that the elastic restoring force is not so strong. For example, the elastic restoring force is formed of hard urethane foam. Alternatively, it may be formed of a plastic plate or cardboard impregnated with a resin.

The edge 15 at the lower end of the laminate 10 shown in FIG.
Is valley-folded at the center line Ly0 extending in the center in the horizontal direction (X direction) and in the vertical direction (Y direction), and the left and right halves of the edge 15 extend on the virtual line Lz extending in the thickness direction (Z direction). Joined together. The upper edge 14 is in the horizontal direction (X direction)
Are bent along a bending line Ly1 set at approximately 1/4 from both ends of each of the edges 14, and the edges 14 are bonded to each other.

The edges 16 and 16 on both sides in the lateral direction (X direction)
Are bonded to each other at a portion of a virtual line Lα extending obliquely in the vertical direction in a palm-to-palm alignment. In addition, only the upper and lower portions of the edges 17 and 17 provided with the elastic members 18 and 18 except for the elastic members 18 and 18 are bonded to each other. The joining of these edges is performed by bonding using a hot-melt adhesive, heat sealing, or a combination of an adhesive and a heat seal.

As a result, as shown in FIG. 1 and FIG.
In the bag 1, the edges 14 are joined together at the upper end 2 to form a joint 14a and closed, and the edges 15 are joined together at the lower end 3 to form a joint 15a. Closed. The joining portion 14a of the upper end 2 extends in the lateral direction (X direction), the joining portion 15a of the lower end 3 extends in the thickness direction (Z direction), and the joining portions 14a and 15a extend in directions orthogonal to each other. Is a so-called tetrapot type three-dimensional shape.

On the body mounting side 4, a joint 16a is formed by joining the edges 16 together, and on the upper end 2 side, a joint 17a is formed by joining the edges 17 together.
At a position close to the upper end 2, and preferably at a position substantially continuous with the upper end 2, the opening 20 in which the elastic members 18 are opposed to each other.
Are formed. The opening 20 has an upper end 2 and a lower end 3
And a vertically elongated shape (slit shape) extending in the vertical direction. The boundary 30 is provided so as to surround the opening 20, and the rigidity of the laminate 10 is reduced in a certain range of the region 31 surrounding the opening 20.

A urine absorbing space 21 having a relatively large internal volume is formed inside the bag body 1 on the lower end 3 side of the portion where the opening 20 is formed. As shown in FIG. 4, the back side 5 opposite to the body wearing side 4 is substantially triangular, but no joint is formed on this back side.

Further, in a preferred embodiment, FIG.
As shown in FIGS. 4, 5, and 6, the elastic sheet 22 is provided inside the inner sheet 11 of the laminated body 10 forming the back side 5. As shown in FIG. 8, the elastic sheet 22 is attached to the back side 5 so as to extend from the position facing the opening 20 toward the urine absorbing space 21 along the vertical direction (Y direction) of the bag 1. Have been.

The elastic sheet 22 is preferably a liquid-permeable, bulky air-through nonwoven fabric having a thickness of, for example, about 1 to 50 mm. Specifically, it is an air-through nonwoven fabric made of fibers such as polyethylene, polypropylene, polyethylene / polyester, and polyester.

When the elastic sheet 22 is provided,
In the use state shown in FIG. 2, the bag 1 formed of the laminated body 10 can be prevented from being bent or broken by an external force such as an attaching force of a diaper worn outside, and the bag 1 can be prevented from being used during use. A sufficient volume of urine holding space can be formed inside. Therefore, the elastic sheet 22 has a function of reinforcing the bag 1. When the elastic sheet 22 is liquid-permeable, it functions to guide urine discharged into the bag body downward in the vertical direction of the bag body 1. As described above, the elastic sheet 22 may have a function of inducing urine.

The elastic sheet may be adhered to the outer surface of the outer sheet 12 or may be bonded to the outer sheet 12 and the absorbent core 1.
3 or between the inner sheet 11 and the absorbent core 13.

When using the male urine absorption pad, the body mounting side 4 is directed to the lower abdomen of the body, and both ends of the elastic members 18 and 18 in the vertical direction (Y direction) are grasped with fingers as shown in FIG. Gives compressive force in the vertical direction. Then, each elastic material 1
The buckles 8 and 18 are buckled and deformed in the direction in which they open from each other, and
Is opened to the left and right. As shown in FIG. 3, when the penis 25 is inserted into the bag 1 through the opening 20 and the compressive force applied to the elastic members 18 is removed, the elastic members 18 are elastically restored, and The base part of 25 is elastic material 18,
18, lightly squeezed from both sides in the lateral direction and held.

When an external force acts on the urine absorbing pad, such as when the diaper is worn from the outside after the urine absorbing pad is worn, or when the wearer's body position changes during the wearing, the area of the opening 20 is reduced. Since the laminate 10 can be relatively freely deformed at 31, when the urine absorbing pad moves, this moving force is absorbed by the deformation of the region 31,
An excessive force does not easily act on the opening 20. Therefore, it becomes difficult for the penis 25 to come off from the opening 20. Also, even if an external force acts on the urine absorbing pad, the wearer's penis 25
No excessive force acts on the wearer, and the wearer does not feel uncomfortable. In addition, since the absorption core 13 is also provided in the region 31 surrounding the opening 20 of the laminate 10, the amount of absorption in the peripheral portion of the opening 20 does not extremely decrease.

The region 3 other than the region surrounding the opening 20
In No. 2, since the laminate 10 has relatively high rigidity, the bag 1 is not easily deformed by the external force. In particular, in this embodiment, since the elastic sheet 22 is provided, the bag 1 is unlikely to be bent or broken. Therefore, a space for retaining and absorbing excreted urine is maintained. That is, stable absorption performance is obtained, and excreted urine is not sufficiently absorbed as in the related art, and does not flow out to the opening 20.

The elastic members 18, 18 are made of a foam material or the like, and lightly press the penis 25 by the restoring force in the buckling deformation, so that the pressing force applied to the penis 25 is extremely weak. Further, as shown in FIG.
When the concave portion 18a and the convex portion 18b are formed on the opposing surfaces of the pendulums 8 and 18, the concave portion and the convex portion come into contact with the penis 25, and the friction between the penis 25 and the elastic members 18 can be suppressed. 25 is less likely to come off the opening 20.

Further, since the opening 20 is formed in the side surface between the upper end 2 and the lower end 3 so as to be long in the vertical direction,
When the penis 25 is hardly detached in the lateral direction with respect to the opening 20 in a state where the penis 25 is inserted into the bag 1 from the opening 20, for example, when the posture of the human body moves and the pad tries to move in the diaper. In addition, it becomes difficult for the penis 25 to come off from the opening 20.

Another embodiment of the present invention shown in FIGS. 10A and 10B will be described. In the embodiment shown in FIG. 10, the thickness and density of the absorbent core 13 forming the laminate 10 are uniform over the entire area of the bag 1. That is, the opening 2
The rigidity of the laminate is the same in the region 31 surrounding 0 and in the other region 32. However, a deformation boundary 30a or 30b is formed at the boundary between the regions 31 and 32.

In FIG. 10A, the absorption core 13 is made thinner at the deformation boundary portion 30a, or an embossed or heat embossed portion 35 is formed. The thin portion and the embossed portion may be formed linearly at the boundary between the region 31 and the region 32, or may be formed intermittently along the boundary, for example, in an intermittent dot shape.

In FIG. 10B, the absorbing core is partially removed at the deformed boundary 30b, and a thinned portion 36 of the laminate 10 is formed at the deformed boundary 30b.

In FIGS. 10A and 10B, the rigidity of the laminated body is the same in the region 31 surrounding the opening 20 and in the other region 32, but the region 31 and the region 32 are deformed. It is divided by the boundary 30a or 30b. Therefore, when an external force acts on the bag body 1 with the urine absorbing pad attached, the region 31 surrounding the opening 20 is different from the other region 32 in the deformation boundary portion 30a or 30b.
Is easily deformed at the boundary, and as a result, the opening 2
0 hardly comes off the penis 25.

However, as described above, it is preferable that the rigidity of the region 31 is lower than that of the region 32, and that the boundary between the regions 31 and 32 is provided with the deformed boundary portion 30a or 30b shown in FIG.

In the male urine absorption pad of the above embodiment, the elastic members 18, 18 are provided in the opening 20, but the elastic members 18, 18 are not provided, and the gap between the edges of the laminate is provided. A slit-shaped opening 20 may be formed. In addition, the opening 20 has a shape that slightly widens in the lateral direction (X direction),
By providing a side leak preventing means such as a gather including a urine leak in close contact with the body, this portion can be used by attaching to a female urinary organ. It can also be used for infants and infants.

The bag body 1 is not limited to the tetrapot type as shown in FIG. 1, but may be a square, a cylinder, a triangular pyramid, or the like having an opening at one end. Good.

[0051]

As described above, the urine absorbing pad of the present invention is
It is stably attached to the body, and even if an external force acts, the position of the portion attached to the urinary organ is less likely to be displaced, and urine is less likely to leak.

When the elastic sheet is provided, the urine absorbing pad itself can be prevented from being deformed, so that the absorption performance is stabilized, and the excreted urine is not sufficiently absorbed and flows out to the opening. Absent.
