Description

  The present invention relates to an absorbent article such as a sanitary napkin, a panty liner, and an incontinence pad for absorbing menstrual blood, urine, etc., and relates to an absorbent article that can be processed without leaking the whole body fluid.

  Conventionally, as an absorbent article such as a panty liner, sanitary napkin, incontinence pad, a liquid-impervious back sheet such as a polyethylene sheet or a polyethylene sheet-laminated nonwoven fabric, and a liquid-permeable top sheet such as a nonwoven fabric or a liquid-permeable plastic sheet There is known an intervening absorber made of cotton-like pulp or the like.

Many improvements have been made to this type of absorbent article, and various means for preventing body fluid leakage have been taken. As one of these body fluid leakage preventing means, there is a technique for forming a concave groove by hot embossing. For example, in Japanese Patent Application Laid-Open No. 11-33054, pulp is squeezed and deformed with fit embossed in the shape of a medium-high shape of an absorbent body that is uniformly stacked, and a leak-proof groove is provided around the middle-high part. Thus, a technique for preventing diffusion (leakage) of body fluid has been proposed, and Japanese Patent Application Laid-Open No. 2001-190595 proposes a body fluid treatment article having a recess for allowing body fluid to flow in. Further, in JP-A-9-28729, there is provided a sanitary napkin which is provided with a cushion layer over the entire width of the rear end portion of the base layer absorbent body and prevents body fluid from leaking to the rear side through a rupture at bedtime. Proposed.
JP-A-11-33054 JP 2001-190595 A JP-A-9-28729

  However, the function of the concave groove of Patent Document 1 described above is to suppress further diffusion by flowing body fluid flowing along the surface of the liquid-permeable top sheet into the concave groove, For example, when a large amount of bodily fluid or the like is discharged instantaneously, the structure is not configured to hold and absorb the bodily fluid so as not to leak. That is, the amount of body fluid to be discharged changes from time to time, and a large amount of body fluid may be discharged instantaneously or may be discharged little by little. Therefore, when a large amount of bodily fluid is discharged instantaneously, it is not necessary to simply suppress further diffusion by the concave groove, and it is necessary to ensure that the bodily fluid can be treated with the concave groove. In addition, some body fluids flow in the front-rear direction as they are, and other body fluids flow while diffusing. In particular, body fluids may leak in the width direction while diffusing, and thus need to be processed quickly.

  In Patent Document 2, the body fluid is stored and retained by providing a recess on the upper surface of the absorbent body. However, if a large amount of body fluid flows from one place, there is a risk of overflow, and the body fluid that has flowed into the recess is successfully introduced. Need to control.

  Furthermore, in particular, in order to prevent after-leakage at bedtime, such as a napkin for nighttime, as in the invention described in Patent Document 3, it is not possible to seal the gap between the cracks by simply providing a cushion layer. There were problems such as being unable to prevent back leakage effectively.

  Therefore, the main problem of the present invention is to provide an absorbent article with a high leakage prevention effect that allows the absorbent body to reliably absorb and hold the body fluid without pre-leaking even when a large amount of body fluid or the like is discharged instantaneously. Is to provide.

  As the present invention according to claim 1 for solving the above-mentioned problem, a first curve comprising a curved line that bulges to the front end side of the absorbent article in a plan view on the upper surface of the front absorbent body of the absorbent article. And a second curve that is located on the front end side of the first curve and that is formed of a curved line that bulges to the front end side of the absorbent article, and whose both end portions are respectively joined to both end portions of the first curve. An absorbent article is provided in which a partitioned closed region portion is recessed from the upper surface side to form a concave front side body fluid reservoir.

  As the present invention according to claim 2, there is provided the absorbent article according to claim 1, wherein the front side body fluid storage part has a pseudo crescent shape in plan view.

  In the first and second aspects of the present invention, the front body fluid reservoir is formed on the upper surface portion of the front side absorber, typically in a pseudo crescent shape by the first curve and the second curve. In the present invention, the first curve defining the pseudo crescent-shaped body fluid reservoir is that when there is a body fluid flowing while diffusing, the body fluid diffused on both sides more quickly flows into the body fluid reservoir than the body fluid flowing in the center. It functions to prevent side leakage by allowing the second curve to diffuse in the reservoir by guiding the body fluid that has flowed into the body fluid reservoir to both sides along the curved shape, Even when a large amount of body fluid flows from one place, it functions to prevent overflow.

  According to a third aspect of the present invention, the absorbent article has side embosses on both side portions on the upper surface side of the absorbent body, and both end portions of the front side body fluid storage portion are coupled to the side embossing. The absorbent article as described in any one of -2 is provided.

  In the present invention described in claim 3, the boundary shape defining the body fluid reservoir is defined, and both ends are connected to the side emboss. The shape of the first curve and the second curve that define the body fluid storage part is, for example, a pseudo-crescent shape, and part of the body fluid that flows into the body fluid storage part is absorbed by the absorber on the bottom surface. The body fluid that has not been absorbed gradually narrows down in the course of flowing laterally, and finally flows into the groove of the side emboss and is absorbed by the absorber. By adopting the above-described flow control with respect to the body fluid flowing into the body fluid reservoir, it is possible to reliably absorb and hold the absorber without leaking.

  As the present invention according to claim 4, there is provided the absorbent article according to any one of claims 1 to 3, wherein the body fluid storage amount of the front body fluid storage part is 10 cc at the maximum.

  As this invention which concerns on Claim 5, the absorber width direction dimension of the said front side body fluid storage part is 20 to 80% with respect to an absorber width, The absorbent article in any one of Claims 1-4 is provided. Is done.

The sanitary napkin 1A includes a liquid-impermeable back sheet 2 made of a polyethylene sheet or the like, a liquid-permeable top sheet 3 that allows permeation of menstrual blood or cage, etc., and an intervening space between the two sheets 2 and 3. Absorbent bodies 4 and 6 made of cotton-like pulp or synthetic pulp, etc., crepe paper 5 surrounding the absorbent body 4 for maintaining the shape of the absorbent body 4 and improving diffusibility, and the abbreviation of the absorbent body 4 Consists mainly of a pair of left and right three-dimensional gathers BS, BS provided with a side edge portion as a standing base end and projecting from the body fluid discharge portion H to the surface side in a predetermined section in the front-rear direction, and the absorption In the periphery of the body 4, the outer edges of the liquid-impermeable back sheet 2 and the liquid-permeable top sheet 3 are joined at the upper and lower edges by an adhesive such as hot melt or an adhesive means such as heat seal. In addition, the liquid-impervious backsheet 2 extending laterally from the absorbent body 4 at both side edges and the side nonwoven fabric 7 forming the three-dimensional gather BS are adhesives such as hot melt. Wing-like flaps W and W that are joined by an adhesive means such as heat seal or the like and project sideways by the laminated sheet portion of the liquid-impermeable back sheet 2 and the side nonwoven fabric 7 are formed. the second wing-shaped flaps W _B to the portion located on the buttocks _side, W _B are formed.

Hereinafter, the structure of the sanitary napkin 1A will be described in detail.
As the liquid-impervious backsheet 2, a sheet material having at least water shielding properties such as polyethylene is used. The water- and moisture-permeable sheet material is a microporous material obtained by melting and kneading an inorganic filler in an olefin-based resin such as polyethylene or polypropylene to form a sheet, and then stretching in a uniaxial or biaxial direction. A sheet is preferably used. One or a plurality of adhesive layers (not shown) are formed on the non-use side (outer surface) of the liquid-impermeable back sheet 2 so as to fix the sanitary napkin 1A to the underwear when worn on the body. It has become.

  Next, the liquid-permeable top sheet 3 is preferably a porous or non-porous nonwoven fabric or a porous plastic sheet. As the material fibers constituting the nonwoven fabric, in addition to olefins such as polyethylene or polypropylene, polyesters, polyamides, and other synthetic fibers, regenerated fibers such as rayon and cupra, and natural fibers such as cotton can be used. A nonwoven fabric obtained by an appropriate processing method such as a method, a spun bond method, a thermal bond method, a melt blown method, or a needle punch method can be used. Among these processing methods, the spunlace method is excellent in terms of flexibility and drapeability, and the thermal bond method is excellent in terms of being bulky and soft. When a large number of through holes are formed in the liquid permeable top sheet 3, menstrual blood, venom, etc. (hereinafter collectively referred to as body fluid) are quickly absorbed, and the dry touch property is excellent. It will be a thing.

  The absorbent body 4 is not particularly limited as long as it can absorb and retain bodily fluids. Usually, a fluffy pulp mixed with a water-absorbing polymer powder is preferably used from the viewpoint of the absorption function and cost. The absorbent body 4 is preferably surrounded by crepe paper 5 to maintain its shape.

  A middle-high absorber 6 is disposed along the longitudinal direction at the center on the upper surface side of the absorber 4. The thickness of the medium-high absorbent body 6 is preferably 3 to 20 mm, preferably 5 to 15 mm, because if the thickness is too large, the rigidity of the absorbent body increases and the adhesion to the body decreases. Further, side embosses 14 and 14 are formed on both sides of the liquid-permeable top sheet 3 along the substantially longitudinal direction.

On the other hand, the width dimension of the liquid-permeable top sheet 3 is slightly longer than the width of the absorbent body 4 and covers the absorbent body 4 as shown in the cross-sectional views of FIGS. The purpose of the three-dimensional gathered BS is to prevent the permeation of menstrual blood, or the like from the side non-woven fabric 7 different from the liquid-permeable top sheet 3, specifically to increase the feeling of touch. Depending on the case, it is configured using a non-woven fabric material subjected to appropriate water repellent treatment or hydrophilic treatment. The side nonwoven fabric 7 can be made of natural fiber, synthetic fiber, regenerated fiber, or the like and formed by an appropriate processing method. Preferably, the side nonwoven fabric 7 eliminates the feeling of stickiness and prevents stuffiness. For this reason, it is preferable to use a non-woven fabric with reduced basis weight and air permeability. Specifically, it is desirable to use a nonwoven fabric prepared with a basis weight of 18 to 23 g / m ² , and silicon-based, paraffin-based, alkylchromic chloride-based water repellents, etc. to reliably prevent the passage of body fluids. A water repellent nonwoven fabric coated with is preferably used.

As shown in FIGS. 2 and 3, the side nonwoven fabric 7 has an outer portion from the intermediate portion in the width direction from the inner position of the absorbent body 4 to slightly beyond the absorbent side edge to the outer edge of the liquid-impermeable backsheet 2. Adhering with an adhesive such as hot melt over a range, the laminated sheet portion of the side nonwoven fabric 7 and the liquid-impermeable back sheet 2 makes a pair of left and right at the side of the absorbent body substantially corresponding to the body fluid discharge portion H. wing flaps W, to form a W, a second wing-shaped flaps W _B now to the buttocks side _position, to form a W _B. These wing-shaped flaps W, W and second wing-shaped flaps W _B, respectively on the outer surface side adhesive layer 10 ... of W _B, 11 ... comprises a, as shown in FIG. 8, when worn against shorts 30, wherein The wing-shaped flaps W, W are folded back to the opposite side at the position of the folding line RL, and are wound around the crotch portion of the shorts and fastened.

  On the other hand, while the inner side part of the said side nonwoven fabric 7 is folded back substantially double, the thread-like elastic elastic member by which the appropriate position of the both ends or the longitudinal direction was fixed to the height direction intermediate part inside this double sheet | seat 19, and a plurality of, in the illustrated example, two thread-like elastic stretch members 20, 20 are fixed at both ends or at appropriate positions in the longitudinal direction at the upper portion of the thread-like elastic stretch member 19. It is arranged. As shown in FIG. 3, the double sheet portion is folded and laminated in a Z-shaped cross section at the front and rear end portions, and is bonded to the absorbent body 4 side, whereby the thread elastic elastic member 19 is disposed. As the bending points, three-dimensional gathers BS and BS standing on the surface side are formed while forming pockets P and P having openings inward in a cross-sectional shape.

  In the sanitary napkin 1 </ b> A, a concave rear side body fluid storage part 17 is formed on the rear side upper surface portion of the absorbent body 4 by being recessed from the upper surface side of the liquid-permeable surface sheet 3. As shown in detail in FIG. 5, the body fluid storage unit 17 includes a first curve 16 that is a curved line that bulges toward the rear end side of the sanitary napkin 1 </ b> A in plan view, and the first curve 16. Is also located on the rear end side, and is composed of a curved line that bulges toward the rear end side of the sanitary napkin 1A, and both ends are partitioned by second curves 18 that are joined to both ends of the first curve 16, respectively. A closed region portion (shaded region) is formed by recessing from the upper surface side, and both end portions where the first curve 16 and the second curve 18 are joined are rear end portions K of the side embosses 14, respectively. It is bound to K. In this case, the first curve 16 and the second curve 18 may partially include a straight line portion, or may be a compound curve line having a plurality of centers of curvature. The point is that the curved line bulges toward the rear end side of the sanitary napkin 1A as a whole.

Absorber widthwise dimension _{B 1} of the rear-side fluid reservoir 17 20-80% with respect to the absorption body width, and preferably from 40% to 60%. With storage capability is low when the width B ₁ is less than 20% with respect to the absorber width may not be captured body fluid flowing while diffusing. Further, there is a case where body fluid once absorbed into the absorbent body 4 in the fluid reservoir 17 seeps to the outside from the side of the absorbent body 4 in the case where the width B ₁ is greater than 80% of the absorbent width. Further, the absorber longitudinal dimension _{L 1} in the longitudinal direction center line CL of the napkin 1A is 5-30% with respect to the absorbent body length, preferably desirably 10 to 25%. If the absorber longitudinal dimension L ₁ is less than 5% becomes low fluid retention capability. If it exceeds 30%, the bodily fluid reservoir 17 originally stores and holds bodily fluid that has not been absorbed in the process of flowing on the surface, so that the absorber drainage site H becomes too close and the effect intended by the present invention is achieved. Lower.

Further, it is desirable that the body fluid storage amount of the rear side body fluid storage unit 17 is 25 cc at the maximum. In order to absorb the whole body fluid without leaking, a maximum volume of about 25 cc is required. The position of the rear-side fluid reservoir 17, 10 to 30 based on the intersection point P ₁ between the longitudinal center line CL of the second curve 18 and the napkin, with respect to the absorption body longitudinal dimension from the rear end of the absorbent body 4 It is desirable to be in the range of%. If it is less than 10%, the body fluid once absorbed by the absorber 4 in the body fluid reservoir 17 may ooze out from the side edge of the absorber. Moreover, when it exceeds 30%, the absorber blood removal site H becomes too close, and the effect intended by the present invention is lowered.

  As shown in FIG. 5, even when there is a body fluid flowing backward from the body fluid discharge part H, this body fluid flows into the rear body fluid storage part 17 and diffuses outward in the body fluid storage part 17. A part of the body fluid is absorbed by the bottom absorbent body portion of the body fluid storage unit 17, and the body fluid that has not been absorbed is narrowed in the basin on both ends where the first curve 16 and the second curve 18 are joined. Then, it flows into the grooves of the side embosses 14 and 14 and is absorbed by the absorber 4. Thus, by controlling the direction in which the body fluid flows into the body fluid reservoir 17 and increasing the amount of body fluid absorbed, a large amount of body fluid can be reliably absorbed without leaking to the rear side.

On the other hand, in the case of the sanitary napkin 1 </ b> A, a concave front side body fluid storage portion 15 is also formed on the front side upper surface portion of the absorbent body 4 by being recessed from the upper surface side of the liquid-permeable surface sheet 3. The front body fluid reservoir 15 is, like the above-described body fluid reservoir 17, in a plan view, a first curve 13 formed of a curved line bulging toward the front end side of the sanitary napkin 1A, and a front side of the first curve 13 A closed region portion that is located on the end side and that is formed by a curved line that bulges toward the front end side of the sanitary napkin 1A and that is divided by second curves 12 that are joined at both ends to the both ends of the first curve 13, respectively. A (shaded area) is formed so as to be recessed from the upper surface side, and both ends where the first curve 13 and the second curve 12 are joined are joined to the front end of the side emboss 14 respectively. The width _{B 2} of the front-side fluid reservoir 15 the same reason as the rear-side fluid reservoir 17, 20-80% relative absorber width, and preferably from 40% to 60%. Further, the absorber longitudinal dimension _{L 2} in the longitudinal center line CL of the napkin 1A is the same reason as the rear-side fluid reservoir 17, 3% to 30% with respect to the absorbent body length, preferably 5 to 15 % Is desirable.

Furthermore, it is desirable that the body fluid storage amount of the front body fluid storage unit 15 is 10 cc at the maximum. In order to absorb the whole body fluid without leaking, a maximum volume of about 10 cc is required. Position of the front-side fluid reservoir 15, the crossings P ₂ between the longitudinal center line CL of the second curve 12 and the napkin 1A, the same reason as the rear-side fluid reservoir 17, of the absorbent body 4 It is desirable that it is located in the range of 10 to 20% with respect to the longitudinal dimension of the absorber from the front end.
