Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to sanitary napkins, urinary incontinence pads, and other body fluid absorbing articles.

[0002]

2. Description of the Related Art Conventionally, in sanitary napkins, urinary incontinence pads, and other bodily fluid absorbent articles, in order to prevent lateral leakage of bodily fluids and to improve the wearing feeling of the wearer, the absorbent articles have been used. There is one in which both sides are raised and three-dimensional side flaps are provided.

[0003]

However, the absorbent article is worn on the crotch of the wearer, and the crotch is rounded in the vertical and horizontal directions. The flap is formed by linearly rising on the surface of the absorbent article. Therefore, if you wear the absorbent article while bending it to match the curve inside the inner crotch of the wearer,
The straight side flap rises and collapses, making it impossible to stand up three-dimensionally.
As a result, the body fluid does not fit, and a gap is formed in the gap between the skin and the side flaps. The body fluid leaks from the gap to the outside, and the undergarment or clothes may be stained.

Therefore, when an elastic body is inserted into the side flap to form a three-dimensional gather, the absorbent article and the three-dimensional gather are curved in an arc shape in the length direction toward the skin contact side due to the contraction force of the elastic body. Therefore, in the length direction, it is easy to adhere to the crotch of the wearer. However, when worn on the crotch of the wearer, both sides of the three-dimensional gather remain linear,
This three-dimensional gather is pressed by the inner thigh that has an arc shape, the rising part is crushed, it does not rise well,
The side leakage prevention function could not be sufficiently exhibited, and the wearing feeling was also poor.

In order to solve the above-mentioned drawbacks, there is a sanitary napkin as described in Japanese Utility Model Publication No. 3-9698. In this sanitary napkin, the side flap and the end flap are formed by compressing the outer peripheral portion so as to be thin. Then, the central portion of the side flap is folded back to the skin contact surface side, and the entire folded portion is fixedly fixed by heat fusion or the like to form a fixed portion. By this fixing, the sanitary napkin is narrow at the fixing portion of the side flap, and wide at the end flap side. Also, on the side flap, a wall surface having a slope is formed in the length direction,
The wall is intended to prevent lateral leakage of bodily fluids.

Accordingly, the above-mentioned sanitary napkin is narrow at the fixing portion of the side flap and gradually widens in the direction of the end flap, so that both sides have an inner arc shape, and fit the inner crotch of the wearer. Then, the sanitary napkin is prevented from being pushed inside by being pressed by the inner thighs during mounting. Furthermore, since the flat sanitary napkin is attracted to the skin contacting surface side by the fixing of the fixing portion, and the side shape becomes arcuate in the length direction, the sanitary napkin is attached to the wearer's crotch. It also fits in the front-back direction of the part. In this way, the sanitary napkin fits the wearer's rounded crotch in both the length direction and the width direction, so it is difficult for the sanitary napkin to twist or shift due to movement during use, and a good wearing feeling Can be obtained.

However, in the above-mentioned conventional example, since the fixing portion of the side flap is compressed and formed thin and flat, a gap is generated between the fixing portion and the skin.
For this reason, the body fluid causes lateral leakage from the gap between the fixing portion and the skin, and the lateral leakage preventing function is insufficient.

[0008] The present invention is to solve the above-mentioned problems, and aims to efficiently prevent lateral leakage of body fluid by raising both sides of the body fluid-absorbing article to form a three-dimensional structure. Things. In addition, by forming the absorbent article three-dimensionally, both sides of the absorbent article are formed into an inner arc shape, and are also curved in an arc shape in the length direction, so that the absorbent article is three-dimensionally contacted in the front-rear and left-right directions of the wearer's crotch. It is intended to obtain a good feeling of wearing without generating any gaps. Then, it is possible to form the absorbent article having the above-mentioned effects at a low cost without any trouble or material.

[0009]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention has a structure in which a water-permeable topsheet and a non-water-permeable leakproof sheet wider than the topsheet are provided with a topsheet. Also, a narrow body fluid-absorbing absorption layer is interposed, and both sides of the leak-proof sheet are folded back to the topsheet side and laminated with the topsheet to form side flaps on both sides of the absorption layer. It is folded back to the top sheet side to form a pair of folded pieces, and the absorbent layer side of the central portion in the length direction of the pair of folded pieces with respect to the folded edge is fixed to the top sheet at a fixed length to form a fixed portion. By forming, the inner edge of the folded piece is raised to form a rising portion.

[0010] Folding of the leak-proof sheet toward the top sheet may be performed by disposing a top sheet on the lower surface of the folded leak-proof sheet.

In addition, the folding of the leak-proof sheet toward the top sheet may be performed by disposing the top sheet on the upper surface of the folded leak-proof sheet.

The rising portion may have a rising width at the fixed portion of 5.0 mm to 30.0 mm.

The fixing part has a fixing length of 10.0 mm.
It may be set to 100.0 mm.

The folded piece may have an elastic body inserted therein.

[0015]

According to the present invention, as described above, a folded piece formed by folding the side flap toward the topsheet is fixed to the topsheet at a fixed length on the absorption layer side from the folded edge. Therefore, when the napkin body is stretched in the length direction during use, the inner edges of the folded pieces rise on both sides of the absorbent layer around the fixed part, and the side flaps have wall-shaped rising parts from the center to both ends. It is formed.

Further, since the side flaps are folded inward to form a folded piece to form a fixed portion, the absorbent article is narrow at this fixed portion, and both end portions in the length direction are side portions. Because the flap wrap is not fixed,
It is wide at both ends. The rising portion has a steep inclination angle of the wall surface at the fixed portion and gradually forms a wall surface having a gentle inclination angle toward the distal end portion. Therefore, a smooth curve is drawn between the narrow portion of the fixed portion of the absorbent article and the wide end portions, and the shape fits the roundness of the inner thigh of the wearer. Therefore, as in the case of linearly formed, the rising portion is not crushed or twisted by being pressed by the inner thigh, and the rising portion holds the rising state and comes into three-dimensional contact with the skin.

Further, by fixing the folded piece to the topsheet at the center portion, both end portions are drawn toward the center on the topsheet side, so that the absorbent article is curved in an arc shape in the length direction. Therefore, the absorbent article fits the shape of the wearer's crotch in the front-rear direction. In this way, while forming a constriction on both sides in the width direction, a three-dimensional absorbent article having an arc shape in the length direction is obtained, and when worn on the crotch of the wearer, the skin and the absorbent article There is no gap in the space between the two, and the fitting is ensured. In addition, since the rising portion keeps the rising state without being bent by the inner thigh of the wearer, the rising portion fits three-dimensionally and prevents a gap with the skin.

Then, while wearing the absorbent article of the present invention,
When the bodily fluid is discharged from the wearer, the bodily fluid diffuses on the topsheet, penetrates into the topsheet, and is quickly absorbed by the absorbent layer. Further, since the absorbent article has a three-dimensional boat-like shape in both the length direction and the width direction by the fixing portion and the rising portion, the bodily fluid can be easily received at the central portion of the absorbent article. When a large amount of bodily fluid is released from the wearer, the bodily fluid cannot be absorbed at the central portion, and penetrates laterally on the topsheet to reach the side flaps. Since the side flap forms the rising portion with the leak-proof sheet, the body fluid is blocked by the rising portion. Further, since the rising portion does not form a gap due to three-dimensional contact with the skin, the blocked body fluid does not leak to the outside, and lateral leakage can be reliably prevented.

Since the side flap does not absorb body fluid, the skin contact portion of the side flap is not stained with the body fluid, and the body fluid does not seep from the skin contact side of the side flap to the back side. Therefore, the dirt of the bodily fluid does not adhere to the underwear or the like, and the wearer does not feel discomfort that the inner crotch is wet. As described above, the rising portion formed by raising the side flaps enables the body fluid to be satisfactorily damped and the lateral leakage to be surely prevented, thereby increasing the sense of security of the wearer.

As described above, the absorbent article of the present invention fits three-dimensionally into the crotch part of the three-dimensional wearer in both the length direction and the width direction, so that it can be used at the time of wearing or after wearing. A good wearing feeling can be obtained without being affected by the movement of the wearer. Also, by reliably preventing lateral leakage, a sense of security is given to the wearer, so that the user's comfort is further improved.

Further, in the process of manufacturing the absorbent article, the leakproof sheet is folded back from both sides to the topsheet side,
When laminating with the top sheet, the top sheet may be arranged on the lower surface of the folded leak-proof sheet, or the top sheet may be arranged on the top surface of the folded leak-proof sheet. When a topsheet is placed on the lower surface of the folded back sheet, the leakproof sheet, the absorbent layer, and the topsheet are arranged in this order, and then both sides of the leakproof sheet are turned back to the topsheet side, and this leakproof sheet is placed. Is laminated on the top surface of the topsheet.

In the case where a topsheet is placed on the top surface of the folded leakproof sheet, an absorbing layer is placed on the top surface of the leakproof sheet, and both sides of the leakproof sheet are folded back to the absorbing layer side.
The folded leak-proof sheet portion is laminated on the upper surface of the leak-proof sheet. Thereafter, a topsheet is disposed on the upper surface of the absorbent layer, and the edge of this topsheet is laminated on the laminated portion of the leakage prevention sheet. In either method, the side flaps are formed of the leak-proof sheet, and the absorbent layer is surely covered with the leak-proof sheet and the topsheet. An easy-to-manufacture method is appropriately selected according to the performance and design of the manufacturing machine.

The rising portion has a rising width of 5.0 mm or more.
If it is formed at 30.0 mm, the rising portion rises well, and has a U-shaped cross section that fits the roundness of both sides in the width direction of the crotch portion of the wearer, and the edge of the rising portion adheres to the skin. The gap is prevented, and the lateral leakage of the body fluid is favorably prevented.
Further, when the rising width of the rising portion is formed to be narrower than 5.0 mm, the rising is low, the edge of the rising portion does not contact the skin, and a gap is generated between the skin and the rising portion. That is, when a large amount of bodily fluid is released, it becomes impossible to sufficiently dampen this bodily fluid to prevent lateral leakage.

Also, if the rising portion is raised more than 30.0 mm, the rising portion does not rise well by its own weight, and is mounted in a state where it falls down inside or outside. There is a possibility that it will not be possible to exert it.
Or, the rising portion is bulky, the topsheet does not make good contact with the skin, the absorbent article feels floating from the skin, and the wearing feeling is poor, and even at the tip of the absorbent article. There is a possibility that a gap may be formed without adhering to the skin, and body fluid may leak from the gap in the front-back direction of the crotch of the wearer.

The fixed part has a fixed length of 10.0 mm.
If formed at -100.0 mm, the absorbent article is narrower at the fixing portion and gradually widens toward the distal end, and the shape of the side flap from the folded piece to both distal ends fits the roundness of the inner thigh of the wearer. Draw a moderate curve. For this reason, when the absorbent article is mounted, the rising portion of the side flap does not buckle due to the press of the inner thigh, and a good wearing feeling can be obtained.

When the fixing length of the fixing portion is shorter than 10.0 mm, a reaction when the absorbent article is spread,
Due to the pressing force at the time of movement during mounting, the fixing portion is released and the rising portion is not formed, and the absorbent article may be planar. In such a case, the effect of preventing the lateral leakage from being caused by the rising portion is not obtained. Further, if the fixing length of the fixing portion is longer than 100.0 mm, a curve from the folded piece of the side flap to the tip portion is not formed, the rising portion becomes linear, and the inner thigh of the wearer is rounded. Will not fit. Therefore, the rising portion is twisted by the inner thigh pressure of the wearer, a gap is generated without three-dimensionally contacting the skin, and lateral leakage prevention is incomplete.

The rising width of the rising portion and the fixing length of the fixing portion are appropriately formed in the above ranges in consideration of the size and thickness of the body fluid absorbent article. The size and thickness vary depending on the type and intended use of the body fluid absorbent article. For example, in the case of sanitary napkins, the thickness changes between a thin type and a normal type. In the case of a thin type, even if the fixing part is formed shorter than the normal type, the fastening does not come off and the rising part does not come off. Can be formed. In addition, the size and the thickness vary depending on the time of use such as night use, day use, and long time use. Also, in the case of the urinary incontinence pad, the optimum fixing length of the fixing portion and the rising width of the rising portion are determined according to the size and thickness of the pad to form the rising portion.

Also, if the folded piece is formed by inserting an elastic body into the inside, the inner edge of the folded piece can be satisfactorily raised,
The curve of the side flap from the folded piece to the tip becomes smoother. Therefore, the rising portion is in flexible contact with the skin, and the wearing feeling is good. Furthermore, since a moderate tension is applied to the rise of the rising portion and a strain is generated, the wearer moves violently while wearing the absorbent article, and is hardly distorted even if the rising portion is strongly pressed by the inner thigh or the crotch portion. It will be. Even if the rising portion is twisted or crushed, the shape is restored to the original shape and surely fits the wearer's skin.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention implemented with a sanitary napkin will now be described with reference to the drawings. As shown in FIG. 2, (1) is a surface sheet, which is a water-permeable material such as a mesh sheet or a nonwoven fabric. Formed. On the back side of the topsheet (1), a leakproof sheet (2) wider than the topsheet (1) and made of a water-impermeable material such as polyethylene is arranged. Also, between the topsheet (1) and the leakproof sheet (2),
A napkin body (4) is formed with a body fluid absorbing layer (3) interposed therebetween. This absorbent layer (3) is made of cotton, pulp,
It is made of a material such as an absorbent polymer, and is formed narrower than the topsheet (1) and the leakproof sheet (2). A sheet-like elastic body (5) made of polyurethane foam or the like is arranged on both sides of the leak-proof sheet (2) and in a wider portion than the top sheet (1).

With the elastic body (5) inside,
After folding (2) from both sides to the topsheet (1) side, the edge of the leakproof sheet (2) is laminated on the top surface of the topsheet (1), and the leakproof sheet ( 1) and the topsheet (2) are fixed by heat fusion. This fastening forms a pair of side flaps (6) on both sides of the napkin body (4). Thus, the side flap is formed by inserting the sheet-like elastic body (5) into the inside to form the side flap (6) and covering the interior of the elastic body (5).
(6) Tension and thickness appear on the whole, making it hard to be distorted, the restoring force against distortedness is increased, and the feeling of contact with the skin is also good. In addition, the edge of the side flap (6) is rounded, so that the contact of the wearer with the skin is soft. Further, if the elastic body (5) is fixed with a tensile force applied thereto,
Due to the restoring force of (5), as shown in FIG.
Gathers are formed in (6), and good curvature is generated in the center direction.

The both ends of the napkin body (4) in the longitudinal direction are also provided on the outer periphery of the absorbent layer (3) with the topsheet (1) and the leak-proof sheet.
(2) and a pair of end flaps (7)
Is formed.

The side flap (6) is folded on both sides from the folded edge (9) to the side of the top sheet (1) to form a pair of folded pieces (8). And this folded piece (8)
As shown in FIGS. 2 and 3, the central portion of the absorption layer (3) inside the folded edge (9) is fixed to the topsheet (1) by a fixed length using an adhesive or heat fusion. Fastening and fixing, fixing part (11)
Is formed. When the napkin body (4) is manufactured, the side flaps (6) are folded back toward the topsheet (1), folded in three in the length direction, and housed in individual packaging. Therefore, the napkin body (4) must be removed from the package when used.
Is taken out and stretched in the longitudinal direction. The inner edge of the folded piece (8) is placed on both sides of the absorbent layer (3) with the fixing part (11) as the center.
(12) stands up. Then, the side flaps (6) are attached to both end flaps (7) from the central fixing portion (11).
, A wall-shaped rising portion (13) is formed.

The napkin body (4) extended as described above
As shown in FIGS. 2 and 3, the folded piece (8) is fixed at a central portion to form a fixed portion (11) having a fixed length. Therefore, the fixed portion (11) is narrow and narrow. And on both end flaps (7) side, as shown in FIGS.
(8) is wide because it is not fixed. The rising portion (13) of the side flap (6) has a steep inclination angle of the wall surface at the fixed portion (11), and both end flaps are provided.
(7) The inclination angle gradually becomes smaller in the direction.

Therefore, the fixing portion (11) of the napkin body (4)
As shown in FIGS. 1 and 2, a smooth curve is drawn between the constriction and the wide side flaps 6 so as to fit the roundness of the inner thigh of the wearer. Furthermore, since the elastic body (5) is inserted into the side flap (6),
(13) Tension and strain appear, the rising is stable,
The fitting feeling is improved, and even when the skin is slightly pressed, the rising portion (13) is less likely to be twisted or crushed, so that the rising portion (13) contacts the skin while maintaining a good standing state.

Also, by fixing the folded piece (8) to the topsheet (1) at the center, both end flaps (7) are provided.
Is drawn toward the center on the top sheet (1) side, and the side surface shape of the napkin body (4) is curved in an arc shape in the length direction.
Therefore, the napkin body (4) also fits the shape of the wearer's crotch in the front-rear direction.

The fixed length of the fixed portion (11) is 10.
It is good to form in 0mm-100.0mm,
It is good to fix at the position where the rising width of (13) is 5.0 mm to 30.0 mm. In any case, the size and thickness of the absorbent article are taken into consideration and appropriately determined within the above range. In the sanitary napkin of the present embodiment, the rising width of the rising portion (13) is formed with a width of 7.0 mm, and the fixing length of the fixing portion (11) is formed with 30.0 mm. As mentioned above,
The side flap (6) has a rising portion (13) with a shape and an angle that fits the curve of the wearer's crotch and inner crotch.
Is formed.

As described above, the sanitary napkin has a constriction on both sides in the width direction and is a three-dimensional product having an arc shape in the length direction. Therefore, the sanitary napkin is attached to the wearer's crotch. Then, the topsheet (1) and the rising part (13)
Thus, the crotch is wrapped around, and there is no gap between the skin and the napkin body (4), so that the napkin body (4) fits the skin reliably. Furthermore, even if it moves violently during mounting, since it fits three-dimensionally in the length direction and the width direction as described above, the napkin body (4) may be distorted,
Displacement is less likely to occur. Even if the starting part is
Even if (13) is twisted or crushed, the rising portion (13) is restored to its original shape and rises satisfactorily by the elastic restoring force of the elastic body (5), and comes into three-dimensional contact with the skin. Therefore, a sense of security is given to the wearer, and a good feeling of wearing is maintained.

When the body fluid is discharged from the wearer while wearing the sanitary napkin, the body fluid is removed from the topsheet (1).
And is quickly absorbed by the absorption layer (3). When a large amount of bodily fluid is discharged, the absorption in the absorbent layer (3) cannot catch up, and the bodily fluid penetrates laterally on the topsheet (1) and reaches the side flap (6). Since the side flap (6) forms the rising portion (13) with the leak-proof sheet (2), the bodily fluid is blocked by the rising portion (13). Further, as described above, since the rising portion (13) maintains the three-dimensional contact with the skin and does not form a gap, the rising portion (13)
The body fluid blocked by (13) does not leak to the outside from the rising portion (13), and lateral leakage can be reliably prevented.
Thereafter, the body fluid blocked by the rising portion (13) passes through the topsheet (1) and is surely absorbed by the absorbing layer (3).

Further, a rising portion formed of the leak-proof sheet (2)
Since (13) does not absorb body fluid, the skin contact portion of the rising portion (13) is always in a dry state, and gives the wearer a good feeling of use. Furthermore, since the leak-proof sheet (2) is formed by folding back from the back surface to the skin contact side, the back surface of the napkin body (4), which is the portion that contacts the underwear, and the edge of the side flap (6) No body fluid seeps out. Therefore, the underwear and the clothes are less likely to be stained by the body fluid, and the sense of security of the wearer is further increased.

Further, even when the body fluid penetrates in the direction of the fixing portion (11), the fixing portion (11) does not fix the entire surface of the turning piece (8) but a part of the turning piece (8). Only fixed and fixed, the inner edge (12) is raised, and a three-dimensional rising part
Since (13) is formed, the fixing portion (11) also reliably dams the body fluid and prevents lateral leakage.

In the above embodiment, the side flaps
The elastic body (5) to be inserted into (6) is formed of a sheet-like polyurethane foam, but if it is elastically deformable and the napkin body (6) can be deformed in an arc shape, vulcanized natural The elastic body (5) may be formed using a material such as rubber, synthetic rubber, polyurethane film, polyethylene film, and other thermoplastic elastomers.

In the above embodiment, when the side flap (6) is formed by folding the leak-proof sheet (2) toward the top sheet (1), as shown in FIG.
Although the topsheet (1) is arranged on the lower surface of (2), the topsheet (1) may be arranged on the upper surface of the folded leakproof sheet (2). In the second embodiment, as shown in FIG. 5, the leak-proof sheet (2) is folded from both sides to the absorbent layer (3) side, and the folded leak-proof sheet (2) is placed on the upper surface of the main body of the leak-proof sheet (2). To be laminated. Then, a topsheet is provided on the upper surface of the absorption layer (3).
After arranging (1) and laminating the edge of the topsheet (1) on the layered portion of the leakproof sheet (2), the outer periphery of the absorbent layer (3) is used to form the leakproof sheet (2) and the topsheet. (1) is fixed by heat fusion to form a side flap (6).

In the above embodiment, the present invention is used for a sanitary napkin. However, the present invention can be used for urinary incontinence pads and other body fluid absorbing articles.

[0044]

Since the present invention is constructed as described above, rising portions are formed on both sides of the body fluid-absorbing article, and the shapes on both sides of the body fluid-absorbing article are formed as arc-shaped recesses so that the wearer's inner crotch can be obtained. 3D fit. In addition, it is also curved in the length direction so as to fit the roundness of the crotch of the wearer. Thus, by fitting three-dimensionally to the wearer's skin, the wearer can be given a good feeling of wearing. In addition, since the rising portion rises three-dimensionally and comes into contact with the skin without any gap, it is possible to satisfactorily dampen body fluids and reliably prevent lateral leakage.

Further, since a product having the above-mentioned effects can be easily formed simply by folding the side flaps inward and fixing and fixing a part thereof, it is possible to form an inexpensive product without labor and cost. You can do it.
