Description

  The present invention relates to absorbent articles such as sanitary napkins, panty liners, and incontinence pads for absorbing menstrual blood, vaginal discharge, and the like, and more specifically, a concave portion formed of a combination of a wavy pattern and a dot pattern on a liquid-permeable surface sheet. It is related with the absorbent article which formed.

  Conventionally, as absorbent articles such as sanitary napkins, panty liners, cage sheets, incontinence pads, etc., it consists of a liquid-impermeable back sheet made of polyethylene sheet or polyethylene laminated nonwoven fabric, and a nonwoven fabric or porous plastic sheet. There is known one in which an absorbent body made of cotton-like pulp or the like is interposed between the liquid-permeable surface sheet.

  With regard to the liquid-permeable surface sheet, conventionally, menstrual blood, urine, etc. (hereinafter collectively referred to as body fluid) are diffused in the front-rear direction of the absorbent article to cause leakage in the width direction of the absorbent article (lateral leakage). Various devices have been devised in accordance with purposes such as preventing or reducing the feeling of wetness by reducing the contact area with the skin, and enhancing the texture and cushioning properties. For example, Patent Document 1 below discloses an absorbent article in which concave portions and convex portions extending in the longitudinal direction are alternately formed in the width direction by a surface sheet.

  Moreover, in the following patent document 2, the uneven | corrugated shape is formed in the surface side which contact | abuts skin at the time of wear, The said uneven | corrugated shape is the uneven | corrugated formation sheet | seat in which many hook-shaped parts were formed in parallel with each other, A sanitary napkin is disclosed that is formed by linearly joining a base sheet between each ridge-shaped portion, and having the longitudinal direction of each ridge-shaped portion and the longitudinal direction of the sanitary napkin being the same direction.

Patent No. 4202737 Japanese Patent No. 3617637

  However, all of those disclosed in Patent Documents 1 and 2 are formed on the topsheet in a linear pattern in which a plurality of linear recesses along the longitudinal direction of the absorbent article are arranged in the width direction of the absorbent article. As a result, body fluid diffuses too much in the front-rear direction of the absorbent article along the concave portion of the linear pattern, and pre-leakage and rear-leakage were likely to occur.

  On the other hand, when the surface sheet is joined to the lower layer sheet only by the concave portion of the linear pattern, the convex portion of the surface sheet floats from the lower layer sheet, so that it is difficult for the body fluid to transfer to the lower layer sheet, and the surface residue of the body fluid Has occurred.

Therefore a main object of the present invention is to control the diffusion region of the body fluid, while preventing leakage is to reduce the surface remaining such menstrual blood and textiles.

As the present invention according to claim 1 to solve the above Symbol challenges, in the absorbent article where the absorber is interposed between a liquid-permeable topsheet and the backsheet,

The separation width between the first wavy pattern and the second wavy pattern is formed by alternately repeating the wide portion and the narrow portion in the longitudinal direction of the absorbent article, There is provided an absorbent article characterized in that a dot-like embossed recess is provided in part .

In the first aspect of the present invention, the protrusion of the liquid-permeable surface sheet, which includes at least the body fluid discharge portion, protrudes to one side in the absorbent article width direction along the substantially longitudinal direction of the absorbent article in plan view. first and wavy pattern, a second wavy pattern and the absorbent obtained by inverting the first wavy pattern in the width direction of the absorbent article repeating the projecting curved portion of the Jo curved portion and the other side alternately Embossed recesses in a wavy pattern that are alternately arranged in the width direction of the article and formed so that the protruding curved portion toward the other side has a smaller radius of curvature than the protruding curved portion toward the one side. Since the body fluid flows zigzag in the width direction along the wavy embossed recess, the body fluid is less likely to diffuse in the front-rear direction than when the linear embossed recess is formed, and the diffusion region of the body fluid is controlled by Prevents leakage from It becomes so that. Further, in the present invention, the curvature radius is relatively small by forming the wavy pattern in particular such that the convex curved portion toward the other side has a smaller radius of curvature than the convex curved portion toward the one side. Since the body fluid flow can be suppressed by the projecting curved portion, the body fluid diffusion region in the front-rear direction can be controlled, and leakage can be prevented.

In the present invention, wide portions and narrow portions having a wide separation width are alternately formed between the first wavy pattern and the second wavy pattern. By providing dot-like embossed recesses in whole or in part, the body fluid of the wide part can be easily transferred to the lower sheet material, and the surface residue of the body fluid is reduced. Further, by providing the dot-like embossed recess, the contact area with the skin is reduced, so that the feeling of dampness is suppressed and skin troubles are less likely to occur.

As the present invention according to claim 2 , the embossed recess of the wavy pattern and the dot-like embossed recess are also formed in a region other than the region including the bodily fluid discharge portion, and in a region other than the region including the bodily fluid discharge portion, the fluid discharge portion than the region including the absorbent article according to claim 1, wherein the dot diameter and / or dot depth of the dot-shaped embossed depressions is set to be smaller is provided.

In the invention according to the second aspect , in a region other than the region including the body fluid discharge portion, the role of the dot-like embossed recess is greater in reducing the contact area to the skin than in transferring the body fluid to the lower layer sheet. Therefore, in this region, the dot diameter and / or the dot depth of the dot-like emboss is set smaller than the region including the body fluid discharge portion.

As the present invention according to claim 3, wherein the intermittent portion is formed in the embossed depressions of the wavy pattern, substantially longitudinally claims are provided intermittently in claim 1 of the wave-like pattern absorbent article, 2 to any The absorbent article described is provided.

In the invention described in claim 3 , the intermittent portion is formed in the embossed concave portion of the wavy pattern so that the wavy pattern is intermittently provided in the substantially longitudinal direction of the absorbent article. It is possible to control so as to further suppress diffusion of body fluids, and it is possible to reliably prevent leakage before and after.

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

[Basic structure of sanitary napkin 1]
As shown in FIG. 1, the sanitary napkin 1 according to the present invention has a liquid-impervious back sheet 2 made of a polyethylene sheet, a polypropylene sheet, and the like, and a liquid-permeable surface that allows permeation of blood or vaginal discharge quickly. The sheet 3, the absorbent body 4 made of cotton-like pulp or synthetic pulp interposed between the two sheets 2 and 3, and the absorbent body 4 are surrounded to maintain the shape and improve the diffusibility of the absorbent body 4. A crepe paper 5, a second sheet 6 made of a hydrophilic non-woven fabric laminated on the lower layer side of the liquid-permeable surface sheet 3 and interposed between the liquid-permeable surface sheet 3 and the crepe paper 5, and both sides of the surface The side nonwoven fabrics 7 and 7 are arranged along the longitudinal direction. Around the absorber 4, at the upper and lower edge portions, the outer edge portions of the liquid-impervious back sheet 2 and the liquid-permeable surface sheet 3 are joined by an adhesive such as hot melt or an adhesive means such as heat seal. In addition, the liquid-impervious back sheet 2 and the side nonwoven fabric 7 that extend laterally from the absorbent body 4 at both side edges thereof are bonded to each other by an adhesive such as hot melt or an adhesive means such as heat seal. In addition, a flap portion where the absorber 4 does not exist is formed on the outer periphery.

Hereinafter, the structure of the sanitary napkin 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, as the liquid-permeable surface sheet 3, a porous or non-porous nonwoven fabric or a porous plastic sheet is preferably used. 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. As will be described in detail later, the liquid-permeable surface sheet 3 is provided with a recess made of a combination of a predetermined wave pattern and a dot pattern.

  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 water-absorbing polymer. The water-absorbing polymer is mixed in the pulp constituting the absorber, for example, as 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.

  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 which is excellent in diffusing body fluids quickly prevents reversal of menstrual blood and the like.

  The second sheet 6 made of a hydrophilic non-woven fabric laminated on the lower layer side of the liquid permeable surface sheet 3 is made of, for example, synthetic fibers such as polyethylene or polypropylene, olefin-based, polyester-based, polyamide-based synthetic fibers, rayon, cupra, etc. Natural fibers such as recycled fibers and cotton can be used, and nonwoven fabrics obtained by appropriate processing methods such as the spunlace method, the spunbond method, the thermal bond method, the melt blown method, and the needle punch method can be used. In order to impart hydrophilicity, a method of polymerizing a compound having a hydrophilic group, for example, an oxidation product of polyethylene glycol, in the process of producing a synthetic fiber, or treatment with a metal salt such as stannic chloride, Synthetic fibers can be made to swell or become porous by a method such as partially dissolving the surface to make it porous and depositing metal hydroxide, etc., and applying capillary action to impart hydrophilicity. As will be described in detail later, the second sheet 6 is bonded to the liquid-permeable surface sheet 3 in a predetermined bonding pattern.

  On the other hand, side non-woven fabrics 7 and 7 are provided on both sides of the sanitary napkin 1 along the longitudinal direction and almost the entire length of the napkin 1, respectively. Wing-like flaps W and W are formed by a part of the liquid-impervious back sheet 2 that extends laterally and also laterally.

  As the side nonwoven fabric 7, a water-repellent treated nonwoven fabric or a hydrophilic treated nonwoven fabric can be used from the viewpoint of an important function. For example, if importance is placed on functions such as preventing permeation of menstrual blood or vaginal discharge, or enhancing the touch feeling, water repellent treatment coated with silicon, paraffin or alkylchromic chloride water repellent It is desirable to use a nonwoven fabric. Further, if importance is attached to the absorption of menstrual blood and the like in the wing-shaped flaps W, W, a method of polymerizing a compound having a hydrophilic group, for example, an oxidation product of polyethylene glycol, in the process of producing a synthetic fiber, , By treating with a metal salt such as stannic chloride, partially dissolving the surface to make it porous, and depositing metal hydroxides to swell or make the synthetic fiber porous, applying capillary action to make it hydrophilic It is desirable to use a hydrophilic treated non-woven fabric provided with.

  In the sanitary napkin 1, embosses 10 to 13 having a depth from the skin contact surface side (the surface side of the liquid-permeable surface sheet 3) to the absorber 4 are applied. Embosses 10 are formed on both sides of the body fluid discharge portion H by arcuate curves along the substantially longitudinal direction of the sanitary napkin 1 and having a center of curvature on the napkin longitudinal center line CL side. Further, an emboss 11 is formed along the substantially width direction of the sanitary napkin 1 so as to be spaced forward from the emboss 10. On the other hand, it has a substantially inverted V-shape that is spaced rearward from the emboss 10 and gradually expands from the position on the longitudinal centerline CL toward the rearward side, and the tip thereof is the longitudinal centerline CL. An emboss 12 that is curved to the side is formed. Further, on the front side of the emboss 11, an emboss 13 is formed in a shape such as a heart shape that expands toward the front side and has a front end curved inward for the purpose of distracting the feeling of depression during the menstrual period. Is formed.

[About liquid-permeable surface sheet 3]
In the sanitary napkin 1, as shown in FIGS. 1 and 2, an embossed recess 20 having a predetermined wavy pattern is provided in a region including at least the body fluid discharge portion H of the liquid-permeable surface sheet 3. The embossed recess 20 of the wavy pattern repeats a protrusion 21 on one side and a protrusion 22 on the other side alternately in the napkin width direction along the substantially longitudinal direction of the napkin 1 in plan view. One wavy pattern 23 and a second wavy pattern 24 obtained by inverting the first wavy pattern 23 in the napkin width direction are alternately arranged in the napkin width direction.

  As shown in FIG. 1, the region including the bodily fluid discharge portion H is a region including a region corresponding to the wearer's bodily fluid discharge portion H, and in the illustrated example, on both sides of the bodily fluid discharge portion H. The region J is substantially surrounded by the embosses 10 and 10 formed along the longitudinal direction of the napkin. In the example shown in FIG. 1, the embossed recess 20 having a wavy pattern is also provided in a region other than the region including the body fluid discharge portion H (an outer region beyond the region J).

  By providing the embossed recesses 20 with the wavy pattern, the body fluid flows along the wavy embossed recesses 20. Therefore, the flow of the body fluid is suppressed and the body fluid is more or less diffused than when the embossed recesses are formed linearly. Leakage can be prevented.

  As shown in FIG. 1 and FIG. 2, by providing the embossed recesses 20 of the wavy pattern, a wide portion 25 and a width having different separation widths between the first wavy pattern 23 and the second wavy pattern 24. The narrow portions 26 are formed alternately and repeatedly in the napkin longitudinal direction.

  As shown in FIG. 2, the dimensions of the embossed recesses 20 of the wavy pattern are such that the apex interval T (one cycle) of the projecting portions 21 and 21 is 5.0 to 7.0 mm, and the emboss width B (embossed recess 20 The width S1 of the wide portion 25 in the napkin width direction is 4.5 to 7.5 mm, and the width S2 of the narrow portion 26 in the napkin width direction is 2.0. It is preferable to set it to -5.0 mm.

  The liquid-permeable surface sheet 3 is bonded to the lower planar second sheet 6 at least at the contact surface portion with the bottom surface of the embossed recess 20 of the wavy pattern by an adhesive such as heat fusion or hot melt. It is integrated with the sheet 6 (this manufacturing method will be described in detail later).

  On the other hand, in order to reduce the remaining surface of the body fluid in the wide portion 25 and reduce the contact area with the skin, the sanitary napkin 1 has a dot-like embossed recess 27 in all or part of the wide portion 25. Is preferably provided.

  As shown in FIG. 2 (B), the dot-like embossed recess 27 is formed at an emboss depth substantially equal to the embossed recess 20 of the wavy pattern at least in a region including the body fluid discharge portion H. It is joined at the contact surface portion with the second sheet 6. Thereby, it becomes easy to transfer the body fluid of the wide portion 25 of the wavy pattern to the second sheet 6 of the lower layer, and the surface residue of the body fluid is reduced. Moreover, since the contact area to skin reduces, a moist feeling is suppressed and it becomes difficult to produce skin trouble. In the region including the body fluid discharge part H, it is preferable that the dot diameter of the embossed concave part 27 (the diameter of the bottom part of the embossed concave part 27) is 1 mm or more to increase the bonding area with the second sheet 6.

  On the other hand, in the region other than the region including the bodily fluid discharge portion H, the dot-like embossed recess 27 may be formed with a depth that can be joined to the second sheet 6 as in the above, but FIG. ), The embossing depth may be relatively shallower than the embossing depth of the region including the body fluid discharge portion H, and may not be joined to the lower second sheet 6. Since the role of the dot-like embossed concave portion 27 in the region other than the region including the body fluid discharge portion H is that the reduction of the contact area to the skin is greater than the body fluid transfer to the lower second sheet 6, shallow embossing is performed. This is due to the depth. The embossing depth of the embossed recess 27 in this region is preferably equal to or greater than 80% of the depth of the embossed recess 20 of the wavy pattern. In this area, the dot-like embossed recess 27 can be formed with a shallow embossing depth, or with a dot diameter of less than 1 mm smaller than the dot diameter of the area including the body fluid discharge portion H.

  As shown in FIG. 3, the embossed recesses 20 of the wavy pattern are formed intermittently in the longitudinal direction of the napkin by forming periodic intermittent portions 28, 28... According to the period of the wavy pattern. Can be provided. In the example shown in FIG. 3 (A), an intermittent portion 28 is provided at the top of the protruding portion 21 to one side in the napkin width direction. In FIG. 3 (B), the protrusion to the other side in the napkin width direction is provided. An intermittent portion 28 is provided at the top of the shape portion 22. By providing the intermittent portion 28, it is possible to control the body fluid diffusion in the longitudinal direction of the napkin to be further suppressed, so that leakage before and after can be reliably prevented. Here, when the intermittent length of the intermittent portion 28 is too large, the continuity of the wavy pattern is remarkably impaired, and the body fluid does not diffuse in the front-rear direction of the napkin and may spread in the napkin width direction. May cause leakage. Therefore, in order to ensure a certain degree of continuity of the wavy pattern, the intermittent length of the intermittent portion 28 in the napkin longitudinal direction is preferably within 1 mm.

  As shown in FIGS. 1 and 2, the dot-like embossed recesses 27 may be provided in the entire wide portion 25. In this case, the embossing makes the fiber density of the surface sheet dense and the surface sheet flexible. 4 and FIG. 5, it can be provided in a part of the wide portion 25 in a region other than the region including the body fluid discharge portion H, as shown in FIGS. In the example shown in FIG. 4, every other wide portion along the longitudinal direction of the napkin while the first wavy pattern 23 is located on the left side and the second wavy pattern 24 is located on the right side of the paper. The embossed recess 27 is formed in the wide portion 25 while the second wavy pattern 24 is positioned on the left side and the first wavy pattern 23 is positioned on the right side. Has been. Further, in the example shown in FIG. 5, the embossed recesses 27 are formed in every two wide portions 25 between the first wavy pattern 23 and the second wavy pattern 24, and both adjacent wavy patterns are formed. The embossed recesses 27 are arranged in a zigzag pattern as a whole by shifting the position at which the embossed recesses 27 are formed between 23 and 24 in the napkin longitudinal direction.

  Next, the embodiment of the wavy pattern will be described in detail. As shown in the embodiment, the wavy pattern includes a protrusion 21 on one side in the napkin width direction and a protrusion 22 on the other side. Is a circular arc pattern formed on both sides (FIG. 6 (A)), the protruding portion 21 on one side in the napkin width direction has an arc shape, and the protruding portion 22 on the other side has two curves. One-side arc-shaped pattern (B in FIG. 6B) formed into a shape in which the two sides are butted together, and a protruding portion 21 on one side and a protruding portion 22 on the other side are formed in a linear shape that is refracted. It is possible to form an arbitrary wavy shape such as a pattern (FIG. 6C) such as various combinations of lines that periodically span the napkin longitudinal direction line L on both sides in the napkin width direction.

  Further, when the embossed concave portion 20 of the wavy pattern is a pattern in which the arc-shaped projecting portion 21 curved to one side in the napkin width direction and the arc-shaped projecting portion 22 curved to the other side are alternately repeated, the projecting The ridges 21 and 22 may be arcs having the same radius of curvature, but as shown in FIGS. 2 and 6A, the radii of curvature of the ridges 21 and 22 are made different so as to protrude toward one side. It is preferable to form the protrusion 22 toward the other side of the protrusion 21 so as to have a relatively small radius of curvature. Thereby, since the flow of the body fluid is suppressed in the projecting portion 22 having a relatively small radius of curvature, the diffusion region of the body fluid in the front-rear direction can be controlled and leakage can be prevented.

[Production method of liquid-permeable surface sheet 3]
In manufacturing the liquid-permeable surface sheet 3 described above, as shown in FIG. 7, the first embossing roll 31, the second embossing roll 32, and the anvil roll 33 having a smooth surface are arranged in the vertical direction from the lower side. An embossing roll device 30 arranged side by side is used. The first embossing roll 31 and the second embossing roll 32 are used as a set, and a liquid-permeable surface sheet is passed between the embossing rolls 31 and 32 to give uneven embossing. While passing the liquid-permeable surface sheet 3 between the anvil rolls 33, the lower sheet 2 is made to enter between the second embossing roll 32 and the anvil roll 33, and the liquid-permeable surface sheet 3 and the second sheet 6 are inserted. And at least one side of the second embossing roll 32 and the anvil roll 33 is heated to a predetermined temperature, and the bottom surface of the recess of the liquid-permeable surface sheet 3 and the second sheet 6 are heated. Join by fusion. The joining method of the said liquid-permeable surface sheet 3 and the 2nd sheet | seat 6 is good also as joining by adhesive agents, such as a hot melt.
