JP 2004-181107 A Japanese Patent Laid-Open No. 2004-446

  Looking at the living conditions of people with mild urine leakage symptoms, light incontinence liners tend to continue to wear for a long time, especially for such users that light incontinence liners are less likely to leak In addition to the basic functions, a good feeling of wearing that does not feel strange when worn is required.

  However, in the absorbent article described in Patent Document 1, both the linear compression site and the planar compression site are applied from the skin contact surface side of the surface layer, and this compression site is along the longitudinal direction of the absorbent article. Since it is arranged, all of the compression sites that have become harder due to compression may directly hit the skin, which may deteriorate the feeling of wearing. In particular, a linear compression site in which the compression site is linearly formed along the longitudinal direction of the absorbent article is very effective in preventing leakage because the body fluid is reliably dammed up, but along the roundness of the body. When the absorbent article is bent, a plurality of wrinkles are formed at the linear compression site, and the tips of the wrinkles are sharp and hit the body, which may cause further deterioration of the feeling of wearing such as itching and tingling. .

  Moreover, in the absorbent article of the said patent document 2, since the embossing compression part is comprised by the part which consolidated the nonwoven fabric of the surface material layer, or formed into the film, there exists a possibility that leakage may generate | occur | produce in the embossing of only a surface material. In addition to being high, there was a possibility that all of the hardened embossing directly hit the skin and deteriorated the wearing feeling.

  Then, the main subject of this invention is providing the absorbent article which prevents the leak of a bodily fluid and has a good wearing feeling.

In order to solve the above-mentioned problem, as the present invention according to claim 1, an absorbent body is interposed between the liquid-permeable top sheet and the back sheet, and both sides of the absorbent body are substantially along the longitudinal direction. In the absorbent article provided with embossing,
The embossing is applied to the absorber from the surface side of the absorbent body in a region that does not overlap with the surface embossing that is applied to the liquid permeable surface sheet from the surface side of the liquid permeable surface sheet. With core embossing,
The surface embossing is alternately formed with sections provided with a large area surface embossing formed with a relatively large area and sections provided with a small area surface embossing formed with a relatively small area. The core embossing is formed in a section to which at least the small area surface embossing is applied, and the surface embossing and the core embossing are along a wavy band having a width corresponding to the embossing width of the large area surface embossing. An absorbent article characterized by being formed is provided.

  In the first aspect of the present invention, the embossed material that is applied to both sides of the absorbent body along the substantially longitudinal direction of the absorbent article is applied to the liquid permeable surface sheet from the surface side of the liquid permeable surface sheet. Surface embossing and a core embossing applied to the absorber from the surface side of the absorber in a region that does not overlap with the surface embossing. In this way, by combining the surface embossing that directly touches the skin and the core embossing in which the liquid-permeable surface sheet is interposed between the embossing surface and the skin, the core embossing has the effect of preventing side leakage of body fluids. While maintaining it, the embossing reduces the direct contact with the skin and improves the wearing feeling.

  Here, the surface embossing includes a section provided with a large area surface emboss formed with a relatively large area and a section provided with a small area surface emboss formed with a relatively small area. Since the core embossing is formed alternately in a section to which at least the small area surface embossing is applied, in the section to which the large area surface embossing is applied, the body embossing is performed by the large area surface embossing. In addition to damming, the area where surface embossing and skin are in direct contact is reduced in the section where surface embossing of a small area is applied, and the wearing feeling is improved. On the other hand, in a section where surface embossing of a small area is applied, the effect of humor blocking may be reduced compared to a section where surface embossing of the large area is applied. Therefore, the core embossing is applied to this section. As a result, the body fluid damming effect as a whole is maintained.

In addition, since the surface embossing and the core embossing are formed along a wavy band having a predetermined width, it is possible to secure a certain length for damming the body fluid to some extent as compared with the case where the surface embossing and core embossing are formed linearly in the longitudinal direction of the absorbent article. The side leakage prevention effect is improved, and the flow in the article width direction can be easily changed to the flow in the article longitudinal direction, so that body fluid can be dammed in a wider range.

As the present invention according to claim 2, wherein the surface embossing, the absorbent article according to claim 1 Symbol placement is formed by the longitudinal long linear shapes other than graphic of the absorbent article is provided.

In the second aspect of the invention, when the surface embossing is formed by a linear figure long in the longitudinal direction of the absorbent article, the absorbent article is curved along the roundness of the body so that the linear surface embossing is performed. A plurality of wrinkles are formed on the surface, and the tips of the wrinkles are sharp and cause pain etc. on the skin, so that the surface embossing has a shape other than a linear shape long in the longitudinal direction of such an absorbent article, for example, a circle or a flower shape. The wear feeling is prevented from being deteriorated by forming the absorbent article such as a figure formed with a substantially uniform length in the longitudinal direction and the width direction of the absorbent article.

According to a third aspect of the present invention, the core embossing includes: an inner core embossing formed inside the small area surface embossing; and an outer core embossing formed outside the small area surface embossing. The absorbent article according to claim 1 or 2 is provided.

In the third aspect of the present invention, the core embossing is formed in a section to which at least the small area surface embossing is applied as in the first aspect, and the core embossing is formed inside the small area surface embossing. By forming the inner core embossing formed and the outer core embossing formed outside the surface embossing of the small area, the core embossing rows are formed on both sides of the surface embossing row of the small area. Thus, body fluid can be dammed by a total of three rows of embossing, and the body fluid damming effect is further improved.

As the present invention according to claim 4 , there is provided the absorbent article according to claim 3 , wherein the inner core emboss is formed with a relatively larger area than the outer core emboss.

In the invention of claim 4 , the inner core embossing is formed in a relatively larger area than the outer core embossing, so that most of the body fluid is dammed up by the inner core embossing, and the damming cannot be done here. The body fluid is dammed with a small-area surface embossing and an outer core embossing to prevent side leakage. Moreover, the discomfort at the time of mounting | wearing is improved by forming the outer core embossing which hits the base of a leg with a relatively small area.

As the present invention according to claim 5, core embossed and / or outside the core embossing of the inner, in claim 3, 4 or the relative substantially longitudinal direction of the absorbent article is continuously or intermittently formed The absorbent article described is provided.

In the invention according to the fifth aspect , the inner core embossing and the outer core embossing can be formed continuously or intermittently in the substantially longitudinal direction of the absorbent article. In addition, when formed intermittently, the approximate width of the intermittent part and the absorbent article so as to fill the intermittent part where the small area surface embossing is separated in the longitudinal direction of the article in relation to the small area surface embossing. It is desirable to place the core embossment in a region overlapping in the direction.

As the present invention according to claim 6 , the total length of the core emboss is the sum of the length of the surface emboss of the small area and the length of the core emboss on the line along the substantially width direction of the absorbent article. The absorbent article according to any one of claims 3 to 5, wherein the absorbent article is formed so as to be substantially uniform along a substantially longitudinal direction of the absorbent article.

In the invention according to claim 6 , the core embossing has a total length obtained by summing the length of the surface embossing of the small area and the length of the core embossing on a line along the substantially width direction of the absorbent article. It forms so that it may become substantially equal along the substantially longitudinal direction of the said absorbent article. That is, the core embossing is formed to be narrower by the embossing width of the small area surface embossment at the portion where the small area surface embossing and the absorbent article substantially overlap in the width direction. As a result, the core embossing allows the surface embossing of a small area to have a part of the effect of damming the body fluid on the surface embossing of the small area, reducing the hardening of the absorbent body by the core embossing itself, It has improved.

As the present invention according to claim 7, wherein the embossing is further absorbent according to claim 1 to 6 or which is applied along a substantially transverse direction of the respective absorbent article in the front and rear ends of the absorbent body Articles are provided.

In the invention of claim 7 , in addition to the embossing provided on both sides of the absorbent body, the embossing is applied to the front and rear end parts of the absorbent body along the substantially width direction of the absorbent article, respectively. This prevents leakage of the absorbent article in the front-rear direction.

  As described above in detail, according to the present invention, it is possible to provide an absorbent article that can prevent body fluid from leaking and has a good wearing feeling.

It is the top view to which a part of surface embossing 11 was expanded. It is the top view to which a part of surface embossing 11 and core embossing 12 was expanded. It is the top view which expanded a part of surface embossing 11 and core embossing 12 concerning other forms. It is the top view which expanded a part of surface embossing 11 and core embossing 12 concerning other forms. It is an expanded view of the liner 1 for light incontinence which concerns on the other form example.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  As shown in FIGS. 1 and 2, the light incontinence liner 1 according to the present invention includes a liquid-impermeable back sheet 2 made of a polyethylene sheet, a polypropylene sheet, and the like, urine, menstrual blood, and vaginal discharge (hereinafter summarized). A liquid-permeable surface sheet 3 that quickly permeates the body fluid), an absorbent body 4 made of cotton-like pulp or synthetic pulp interposed between the two sheets 2 and 3, and an absorbent body if necessary. 4 and crepe paper 5 surrounding the absorbent body 4 in order to maintain the shape and improve the diffusibility. Around the absorber 4, the outer edge portions of the liquid-permeable top sheet 3 and the liquid-impervious back sheet 2 extend over the entire circumference of the absorber 4 by an adhesive such as hot melt or a joining means such as heat seal. A peripheral seal portion 8 is formed. Embosses 10 are provided on both sides of the absorbent body 4 along the substantially longitudinal direction of the light incontinence liner 1.

Hereinafter, the structure of the light incontinence liner 1 will be described in detail.
As the liquid-impermeable back sheet 2, a sheet material having at least water shielding properties such as an olefin resin sheet such as polyethylene or polypropylene is used. In addition, a laminated nonwoven fabric obtained by laminating a nonwoven fabric on a polyethylene sheet or the like, or A nonwoven fabric sheet (in this case, the waterproof film and the nonwoven fabric constitute a liquid-impervious back sheet) can be used after substantially impervious to liquid imperviousness by interposing a waterproof film. In recent years, those having moisture permeability tend to be used from the viewpoint of preventing stuffiness. This water- and moisture-permeable sheet material is a microporous sheet obtained by forming a sheet by melting and kneading an inorganic filler in an olefin resin such as polyethylene or polypropylene, and then stretching in a uniaxial or biaxial direction. It is.

  Next, a porous or non-porous nonwoven fabric is preferably used for the liquid-permeable surface sheet 3. Examples of the material fibers constituting the nonwoven fabric include synthetic fibers such as polyethylene or polypropylene, synthetic fibers such as polyester and polyamide, recycled fibers such as rayon and cupra, and natural fibers such as cotton. A nonwoven fabric obtained by an appropriate processing method such as a lace method, a spun bond method, a thermal bond method, a melt blown method, or a needle punch method can be used. Of these processing methods, the spunlace method is excellent in terms of flexibility and the spunbond method is excellent in drapeability, and the thermal bond method and the air-through method are excellent in terms of being bulky and soft.

The absorbent body 4 interposed between the liquid-impervious back sheet 2 and the liquid-permeable top sheet 3 is made of, for example, fluffy pulp and a superabsorbent polymer. The superabsorbent polymer is mixed in the pulp constituting the absorber, for example, as a granular powder. Examples of the pulp include chemical fibers obtained from wood, cellulose fibers such as dissolved pulp, and artificial cellulose fibers such as rayon and acetate. Softwood pulp having a longer fiber length than hardwood pulp functions and It is preferably used in terms of price. Basis weight of the absorbent body 4, for the pulp 10 to 1000 g / m ^2, preferably between 30 to 200 g / m ^2, for the high-absorbent polymer 10 to 500 g / m ^2, preferably from 30 to 100 g / m ² It is desirable to do.

  The absorbent body 4 may be mixed with synthetic fibers. As the synthetic fiber, for example, polyolefins such as polyethylene or polypropylene, polyesters such as polyethylene terephthalate and polybutylene terephthalate, polyamides such as nylon, and copolymers thereof can be used. It may be a mixture. In addition, a composite fiber such as a core-sheath fiber, a side-by-side fiber, or a split fiber having a fiber having a high melting point as a core and a fiber having a low melting point as a sheath can also be used. In the case of a hydrophobic fiber, it is desirable to use a synthetic fiber that has been surface-treated with a hydrophilizing agent so as to have an affinity for body fluids.

  When the crepe paper 5 surrounding the absorbent body 4 is provided as in this example, the crepe paper 5 is interposed between the liquid-permeable surface sheet 3 and the absorbent body 4 as a result. The crepe paper 5 that is excellent in diffusing body fluids quickly diffuses and prevents these body fluids from reversing.

  In the laminated portion of the liquid-permeable surface sheet 3 and the absorbent body 4, a large number of patterns in an appropriate pattern from the surface side of the liquid-permeable surface sheet 3 in the region including at least the urination opening, Dot-shaped embossing 9, 9 ... can be provided.

  Next, the embosses 10 and 10 applied to both sides of the absorbent body 4 will be described in more detail.

  The emboss 10 is formed from the surface side of the absorbent body 4 in a region that does not overlap the surface emboss 11 that is applied to the liquid permeable surface sheet 3 from the surface side of the liquid permeable surface sheet 3. It is comprised from the core embossing 12 provided to the absorber 4. FIG. When the absorbent body 4 is surrounded by the crepe paper 5, the surface emboss 11 and the core emboss 12 are respectively subjected to pressing processing on the absorbent body 4 surrounded by the crepe paper 5.

  As shown in FIG. 1, the surface emboss 11 has a relatively large area emboss 13 formed with a relatively large area with respect to the longitudinal direction of the light incontinence liner 1. Are formed alternately with sections 16 provided with small-area surface embosses 15, 15.

  It is preferable to arrange one figure emboss in the section 14 to which the large area surface emboss 13 is applied. As the planar shape of the emboss, it can be formed by a figure such as a star shape or a heart shape in addition to the flower shape of the illustrated example, and can also be formed by a geometric figure such as a circle, an ellipse, or a rectangle. In addition, the large-area surface emboss 13 may be formed integrally with a continuous compression portion, or may be formed by a combination of a plurality of spaced compression portions as shown in the example. The combined figure can be regarded as one large area surface emboss 13.

The surface embossment 13 having a large area, as shown in FIG. 3, the range length D _A of the major axis of the embossing is 0.5 to 10 mm, preferably it is desirable to form at about 5 mm. Further, when configuring by combining a plurality of compressed portions are the length of the long axis of one compression unit is set to about 0.5 to 6 mm, combined graphic overall diameter of about 10 mm (the D _A It is preferable that it is formed in a size that fits within a circle within the range. Further, the separation distance L _A (the length of the section 16 to which the small-area surface emboss 15 is provided) between the large-area surface embosses 13 and 13 is preferably within a range of 5 to 30 mm, and preferably about 10 to 20 mm. .

  It is preferable that a plurality of surface embosses 15, 15... Are arranged at a predetermined pitch in the section 16 to which the surface emboss 15 having a small area is provided. In the illustrated example, three circular (dot-like) embossments are arranged apart from each other in the substantially longitudinal direction of the light incontinence liner 1. The planar shape of the surface emboss 15 can be formed in various shapes such as an ellipse, a quadrangle, a star, and a heart, in addition to a circle.

The surface embossment 15 of the small area, as shown in FIG. 3, the large area is formed in a small area than the surface embossment 13, the range of the long axis direction of the emboss length D _B of 0.5~6mm Preferably, it is desirable to form with about 1 to 4 mm. The length (pitch) _{L B} between the surface embossing 15, 15 of the small area is preferably in the range of 0.5 to 10 mm, desirably about 1 to 3 mm.

  The planar shape of the surface emboss 11 is preferably formed by a figure other than a linear figure that is long in the substantially longitudinal direction of the light incontinence liner 1. When the surface emboss 11 is formed by a linear figure that is long in the longitudinal direction of the liner, a plurality of wrinkles are formed in the linear surface emboss when the liner curves in the longitudinal direction along the roundness of the body. The tip of the skin may be sharp and cause pain or the like on the skin. As a figure other than the linear figure, a figure formed with a substantially uniform length in the liner longitudinal direction and the width direction, for example, a circle or a flower shape can be used.

  The ratio of the area of the large surface emboss 13 to the area of the small surface emboss 15 is about 5 to 300 times, preferably about 10 to 100 times.

  The surface embossing 11 and the core embossing 12 (embossing 10) are preferably formed along a wavy band having a width corresponding to the embossing width of the surface embossing 13 of the large area. Thus, by forming the emboss 10 along the wavy band, it becomes possible to secure a certain length for damming the body fluid to some extent as compared with the case where the emboss 10 is formed linearly in the longitudinal direction of the light incontinence liner 1. The effect of preventing side leakage of body fluid is improved. Further, the flow from the central portion in the width direction of the light incontinence liner 1 to the outside is easily changed to the flow in the longitudinal direction of the liner by the wavy emboss 10, so that the body fluid can be dammed in a wider range.

  In the case where the emboss 10 is formed in a wave shape, it is preferable that the emboss 10 is formed in a wave shape that is convex inward at the longitudinal center portion of the light incontinence liner 1. As a result, the flow from the central portion of the liner toward the outside can be easily changed to a flow in the liner longitudinal direction at the convex portion inside the wavy emboss 10. Moreover, it is preferable that a wavy shape is made into the area 16 (section in which the core embossing 12 is formed) to which the surface embossing 15 of the said small area is provided in the area which protrudes inside and protrudes outside. It is preferable that the section 14 to which the large-area surface emboss 13 is provided is located in the middle of the convex, that is, in a portion corresponding to the inflection point of these curves. Thereby, the body fluid can be dammed by the core emboss 12 and the small surface emboss 15 at the inside convex portion where the body fluid flow is easily received and the outside convex portion where the body fluid flow is likely to stay. become able to.

  On the other hand, the core emboss 12 is formed in a section 16 to which at least the surface emboss 15 having a small area is provided. That is, the core embossing 12 is disposed so as to fill a portion other than the large-area surface embossing 13, and is discretely disposed so as to be separated by the large-area surface embossing 13 portion as a whole in the liner longitudinal direction. The core emboss 12 extends in such a range that both ends or one end thereof does not overlap with the large-area surface emboss 13 and slightly covers the section 14 where the large-area surface emboss 13 is formed. You may do it.

  The core embossing 12 may be formed continuously like a continuous line along the substantially longitudinal direction of the light incontinence liner 1 (see FIG. 4), or a plurality of compressed portions are spaced apart from each other to light incontinence. You may form intermittently so that it may be arranged along the substantially longitudinal direction of the liner 1 for a use (refer FIG. 5 (A)). When formed continuously, the damming effect of body fluid increases, and when formed intermittently, the part hardened by squeezing becomes intermittent and the skin contact becomes soft. On the other hand, when the core emboss 12 is formed intermittently, there is a concern about the side leakage of body fluid from the intermittent portion. Therefore, as shown in FIG. The part is preferably formed at a position overlapping the surface emboss 15 having a small area in the liner width direction. In other words, the core embossing 12 is desirably formed at a position overlapping with the intermittent portion between the small area surface embosses 15 and 15 in the liner width direction in relation to the small area surface embossing 15. Thereby, even if a body fluid flows out to the outside through the intermittent part of the core embossing 12, it can be dammed by the surface embossing 15 having a small area.

  The surface embosses 15, 15... Of the small area are arranged at the center in the width direction of the wavy band, and the core emboss 12 is formed inside the liner width direction of the surface embosses 15, 15. The inner core embossing 17 and the outer core embossing 18 formed on the outer side in the liner width direction of the small surface embossing 15, 15. Thereby, a compression part comes to be formed over three rows of inner core embossing 17, inner surface embossing 15 of a small area, and outer core embossing 18 in order from the inner side of the liner width direction, and the damming effect of body fluid is achieved. In addition, side leakage can be reliably prevented.

  The inner core embossing 17 is preferably formed with a relatively larger area than the outer core embossing 18. As a result, most of the body fluid is dammed by the inner core embossing 17, and the body fluid that could not be damped here is dammed by the small surface embossing 15 and the outer core embossing 18 to prevent side leakage. become able to. Further, by forming the outer core embossing 18 that is likely to hit the base of the leg with a relatively small area, a sense of incongruity at the time of wearing can be suppressed.

Said inner core embossing 17 and an outer core embossing 18 is preferably embossed minor axis direction of the maximum length _W C, _{W D} is 0.5~5mm respectively. To form the area of the inner core embossing 17 and an outer core emboss 18 in relationship as described above, at least, the maximum length W _C of the minor axis direction of the inner core emboss 17 is a 1~3mm it is desirable, it is preferable that a maximum length _{W D} of the short axis direction of the outer core emboss 18 and the _{W C} is less than 0.5 to 1 mm. Further, the lengths L _C and L _D in the major axis direction are preferably 5 to 30 mm, and more preferably 10 to 20 mm.

  The inner core embossing 17 and the outer core embossing 18 can be formed in various shapes. For example, as shown in FIG. 4, the inner core embossing 17 is formed so that the outer contour line on the inner side in the liner width direction is formed along the side edge of the wavy band, and both ends thereof are defined by the radius of curvature of the wavy band. It can be formed into a thin, substantially crescent shape at both ends connected by a curve having a large radius of curvature. Similarly, the outer core emboss 18 can be formed in a substantially crescent shape.

  In addition to this, as shown in FIG. 5A, the inner core emboss 17 and the outer core emboss 18 are each formed by intermittently arranging a plurality of oval shapes along the wavy band. be able to. Further, as shown in FIG. 5B, the inner core embossing 17 is formed by a substantially equal width continuous line, and the outer core embossing 18 is intermittently arranged with a plurality of long oval shapes along the wavy band. Can be formed intermittently. In this embodiment, most of the body fluid is dammed by the inner continuous linear core embossing 17, and the body fluid that cannot be blocked by the embossing 17 is dammed by the small surface embossing 15 and the outer core embossing 18. I am doing so. Further, as shown in FIG. 5 (C), both ends of the inner core emboss 17 may be formed to be bent inward in the liner width direction. Thereby, the damming effect of the inner core embossing 17 can be improved. Moreover, when forming discretely, you may make it arrange | position intermittently a plurality of circular embossing along the side edge of a wavy zone like the core embossing 18 of the outer side of the figure (C).

As shown in FIG. 6, the core emboss 12 is formed on a line that crosses the wavy band in the width direction (on a line along the substantially width direction of the light incontinence liner 1 and formed by a wavy curve). in the radius of curvature of the radial line), the total length is the sum of the length S _D of the length S _C and the outer core emboss 18 of length S _B and an inner core embossing 17 of the surface embossing 15 of small-area ( It is desirable to form (S _B + S _C + S _D ) so as to be substantially uniform along the wavy band. That is, the inner core embossing 17 and the outer core embossing 18 are formed so as to be narrower by the embossing width of the small area surface embossing 15 in the portion overlapping the small area surface embossing 15 and the liner width direction. As a result, while maintaining the body fluid damming effect in this section, it is possible to reduce the hardening of the absorbent body in the portion where the inner core embossing 17 and the outer core embossing 18 are narrowly formed, and soften the contact with the body. The feeling of wearing will improve. In the illustrated example, the length _SD of the outer core emboss 18 is formed substantially evenly along the wavy band. However, the width of the outer core emboss 18 overlaps the surface emboss 15 having a small area in the same manner as the inner core emboss 17. In contrast to the illustrated example, the outer core emboss 18 may be formed narrow at a predetermined portion, and the inner core emboss 17 may be formed substantially evenly.

  Further, the bandwidth of the wavy band is preferably about 0.5 to 10 mm, and the length of the embossed squeezed portion with respect to this bandwidth is 5 to 95%, preferably 20 to 50%.

  In order to manufacture the light incontinence liner 1, the surface emboss 11 is applied to both sides of the liquid-permeable surface sheet 3 and the core emboss 12 is applied to both sides of the absorbent body 4. The absorbent body 4 and the liquid-permeable surface sheet 3 are laminated on the conductive back sheet 2 and joined by the outer peripheral seal portion 8.
