[Basic structure of sanitary napkin 1]
1 is a developed view of a sanitary napkin 1 according to the present invention, FIG. 2 is a view taken along the line II-II in FIG. 1, and FIG. 3 is a view taken along the line III-III in FIG.

The sanitary napkin 1 includes a liquid-impervious back sheet 2 made of a polyethylene sheet, a liquid-permeable top sheet 3 that allows permeation of menstrual blood, cages, and the like, and an intervening sheet between the sheets 2 and 3. Absorbent body 4 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 substantially side edges of the absorbent body 4 A pair of left and right three-dimensional gathers BS, BS projecting to the surface side in a predetermined section in the front-rear direction so as to include at least a body fluid discharge part, and a pair of right and left three-dimensional gathers BS, Between the BS, it is mainly composed of a pair of left and right surface gathers 20, 20 provided standing on the surface side in the longitudinal direction, and around the absorber 4, at the front and rear end edges thereof The outer edge of the liquid-impermeable back sheet 2, the liquid-permeable top sheet 3 and the surface gathered nonwoven fabric 21 forming the surface gather 20 is joined by an adhesive such as hot melt or an adhesive means such as heat seal. In addition, the liquid-impervious backsheet 2 that extends to the side of the absorbent body 4 at both side edges and the side nonwoven fabric 7 that forms 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 and project laterally by the laminated sheet portion of the liquid-impermeable back sheet 2 and the side nonwoven fabric 7 are formed, and the heel portion is more than this. Second wing-shaped flaps W _B and W _B are formed on the portion located on the side.

Hereinafter, the structure of the sanitary napkin 1 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, but in recent years, a material having moisture permeability tends to be used from the viewpoint of preventing stuffiness. 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 1 to the underwear when worn on the body. It has become. As the liquid-impermeable back sheet 2, a polylaminated nonwoven fabric in which a plastic film and a nonwoven fabric are laminated may be used.

  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. 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. When using a mesh material in which a large number of perforations are formed as the liquid-permeable top sheet 3, menstrual blood, urine and the like (hereinafter collectively referred to as body fluid) are quickly absorbed, It is preferable because it has excellent dry touch properties.

  In the illustrated example, the width dimension of the liquid-permeable top sheet 3 is slightly shorter than the width of the absorbent body 4 as shown in the cross-sectional views of FIGS. The surface gathered non-woven fabric 21 is disposed on both sides of the surface side to the extent slightly outside the width of the absorbent body 4.

  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. When the crepe paper surrounding the absorbent body 4 is provided, the crepe paper intervenes between the liquid-permeable surface sheet 3 and the absorbent body 4 as a result, and the body fluid is removed by the crepe paper having excellent absorbability. It diffuses promptly and prevents reversal of these menstrual blood and the like.

  The absorber 4 may be composed of a single layer absorber, but as shown in FIGS. 2 and 3, the upper layer absorber 4A and the lower layer absorber 4B may be laminated. preferable. The lower layer absorber 4B has a planar shape that defines the outer edge of the absorber arrangement region, and the upper layer absorber 4A is formed in a region that is elongated in the napkin longitudinal direction at the center portion in the width direction, on the use surface side. Arranged to form the mid-high section 6 of the high absorber. The thickness of the middle-high portion 6 is preferably 3 to 20 mm, more preferably 5 to 15 mm, because if the thickness is too large, the rigidity of the absorber 4 increases and the adhesion to the body decreases. An emboss 8 that is closed in the circumferential direction from the surface side of the sheet material covering the surface side of the upper layer absorbent body 4A is provided along the periphery of the upper layer absorbent body 4A, and the inner side thereof. Emboss 9 is formed on the surface. Further, the emboss 8 is not limited to the outer periphery of the upper absorbent body 4A, and the emboss 8 may be provided from the upper surface of the upper absorbent body 4A toward the lower absorbent body 4B. In this case, it is made to perform under high pressure so that the hollow by the emboss 8 may bite into the lower layer absorber 4B. The embossing 8 prevents misalignment of the upper absorbent body 4A and also has the purpose of defining the middle and high portions 6 exactly. The embossing 8 will be described in more detail later.

The three-dimensional gathered BS is a side nonwoven fabric 7 different from the liquid-permeable top sheet 3, specifically for preventing menstrual blood, venom or the like from penetrating, or enhancing the touch feeling, etc. 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 8 to 23 g / m ² , and silicon-based, paraffin-based, alkylchromic chloride-based water repellents, etc., to reliably prevent permeation 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. A pair of left and right wings are bonded to the absorbent body side portion substantially corresponding to the body fluid discharge portion by the laminated sheet portion of the side nonwoven fabric 7 and the liquid-impervious back sheet 2. 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, W outer surface respectively the adhesive layer on the side 12 of the _B ..., 13 ... comprises a, as shown in FIG. 6, 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 15, and a plurality of, in the illustrated example, two thread-like elastic stretch members 16, 16 are fixed at both ends or at appropriate positions in the longitudinal direction on the upper portion of the thread-like elastic stretch member 15. 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, so that the portion where the thread-like elastic elastic member 15 is disposed is arranged. 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.

  As shown in FIG. 2 and FIG. 3, the surface gathered nonwoven fabric 21 forming the surface gather 20 is in a range from both side portions of the liquid-permeable top sheet 3 to a portion slightly beyond the side edge of the absorbent body 4. It is arranged over. Thereby, the surface side of the sanitary napkin 1 has the liquid-permeable top sheet 3 over the longitudinal direction of the center part in the width direction, the surface gathered nonwoven fabrics 21 and 21 on both sides thereof, and the side nonwoven fabric 7 on both sides thereof. 7 appear on the surface.

  The surface gathered nonwoven fabric 21 may be a liquid-permeable material, and the same material as the liquid-permeable top sheet 3 can be used. Here, it is preferable to use the above-mentioned mesh material as the liquid-permeable top sheet 3 and a non-woven material as the surface gathered nonwoven fabric 21. Thereby, in the part over the longitudinal direction of the width direction center part of the napkin 1, since the liquid-permeable top sheet 3 comes to contact a body, it is excellent in liquid permeability and can suppress stickiness, Since the surface gathered nonwoven fabric 21 comes into contact with the body in the portions extending in the longitudinal direction on both sides, the touch can be improved and a comfortable feeling can be given to the wearer.

  The surface gathered nonwoven fabric 21 is provided with a pair of left and right embosses 8 along the substantially longitudinal direction of the sanitary napkin 1 from the surface side, and the outer portion of the embossed 8 is a lower layer sheet material by an adhesive such as hot melt. It is glued to. On the other hand, the inner side portion of the surface gathered nonwoven fabric 21 is folded back almost double as shown in FIG. 4, and at the tip end in the height direction inside the double sheet, at least the emboss 8 is given. A thread-like elastic elastic member 22 fixed at an appropriate position is disposed over the longitudinal direction of a certain range. As a result, a pair of left and right surface gathers 20, 20 standing with the emboss 8 as a base end are formed along the substantially longitudinal direction in the formation region of the emboss 8 in the middle of the three-dimensional gather BS. It has become.

  As shown in FIG. 4, the emboss 8 is applied on at least a surface gathered nonwoven fabric 21 in which the liquid-permeable top sheet 3 is interposed. If it extends to the outer region where the top sheet 3 does not intervene, the absorbent body 4 is exposed when the surface gathers 20 are erected, and it comes into direct contact with the skin, which is not preferable. And as the said embossing 8 is shown by FIG. 4, it is preferable to provide so that it may bite into the lower layer absorber 4B from the surface side of the surface gathered nonwoven fabric 21 in which the liquid-permeable top sheet 3 was interposed. Thereby, the body fluid blocked by the surface gathers 20 is easily absorbed by the absorber 4. Furthermore, the folded state of the surface gather 20 can be reliably maintained by applying the emboss 8 at the double folded portion of the surface gathered nonwoven fabric 21.

  At both ends in the longitudinal direction of the sanitary napkin 1 which is the front and back sides of the longitudinal range to which the embossing 8 is applied, the liquid permeable top sheet 3 is disposed on the inner surface side of the surface gathered nonwoven fabric 21 in order to eliminate discomfort during wearing. The surface is prevented from standing by being adhered to the surface with an adhesive such as hot melt, and the surface gathers 20 are not formed.

  The emboss 8 is provided in a pair of left and right along the substantially longitudinal direction of the napkin 1 from the surface side of the surface gathered nonwoven fabrics 21 and 21 disposed on both sides of the liquid-permeable top sheet 3. In the example shown in FIG. 1, the emboss 8 surrounds the middle and high portions 6 of the absorbent body 4 </ b> A disposed at the center in the width direction of the napkin 1, and the liquid-permeable top sheet 3 at the center and both sides thereof. The surface gathered nonwoven fabrics 21 and 21 are stretched in the longitudinal direction of the napkin 1 so as to be closed in the circumferential direction so that the surfaces of the surface gathered nonwoven fabrics 21 and 21 are substantially along the longitudinal direction of the napkin 1. Paired left and right.

  Here, the pair of left and right embosses 8, 8 applied to the surface gathered nonwoven fabric 21, 21 is formed by gradually changing the separation width in the longitudinal direction of the sanitary napkin 1 in plan view. Thereby, the standing height of the surface gathers 20 standing with the emboss 8 as the base end is arbitrarily changed.

  Next, a pattern for changing the standing height of the surface gather 20 will be described in detail. As shown in FIG. 1, the first pattern has a relatively narrow separation width b1 between the left and right embossings 8 and 8 at a portion corresponding to the blood outlet H. The separation width b2 of the embosses 8 and 8 in the front portion of the portion corresponding to the blood discharge port H and the separation width b3 of the embosses 8 and 8 in the rear portion are set relatively wide. That is, the standing height of the surface gathers 20 formed with the emboss 8 as the base end is relatively low at the portion corresponding to the blood drainage port H and relatively high at the front and rear portions thereof. Thereby, in the part corresponding to the blood drainage port H, the napkin surface and the blood drainage port are brought into close contact with each other so that the fit with the body can be maintained and the body fluid can be prevented from leaking. Furthermore, at the front and rear portions of the blood drainage outlet corresponding portion, the body fluid that is about to diffuse in the diagonally front and rear direction of the blood drainage port can be blocked to prevent the body fluid from leaking. In the illustrated example, the separation width b2 of the front portion and the separation width b3 of the rear portion are formed to be substantially the same width. However, depending on the structure of the body, the separation width b2 of the front portion is set to the rear portion. It may be formed relatively wider than the separation width b3, and vice versa.

  Although the second pattern is not illustrated, in contrast to the first pattern, the separation width of the pair of left and right embosses 8 and 8 is relatively wide in the portion corresponding to the blood outlet H, and blood is discharged. The separation width b2 of the embosses 8 and 8 in the front part of the part corresponding to the mouth H and the separation width b3 of the embosses 8 and 8 in the rear part are set relatively narrow. When formed in this way, the height of the surface gathers 20 is formed relatively high at the portion corresponding to the blood outlet H. As a result, side leakage of body fluid can be effectively prevented, and the wearer can be given a sense of security in appearance against side leakage.

  As shown in FIG. 5, in the third pattern, the pair of left and right embosses 8 and 8 pass through the front end of the surface gather 20 or the vicinity thereof in the longitudinal intermediate portion c of the sanitary napkin 1, By setting a wide separation width in the front and rear parts, a first standing part s1 in the front part from the intermediate part c and a second standing part s2 in the rear part from the intermediate part c are provided. . As a result, the surface gather 20 is not formed in the intermediate portion c, so that the adhesion to the body is improved. On the other hand, in the standing portions s1 and s2, a portion where a gap is easily generated between the body and the napkin surface is formed. It can be covered, and the fit to the body is improved at the same time as preventing the leakage of bodily fluids. Here, in the example shown in FIG. 5, the intermediate portion c is provided in the crotch region behind the blood outlet H, and the first standing portion s1 is the front side of the intermediate portion c and the blood outlet H is The second upright portion s2 is provided on the rear side of the intermediate portion c and corresponding to the groove portion of the flange portion. The emboss 8 in the intermediate portion c is provided across the surface gathered nonwoven fabric 21 and the liquid-permeable top sheet 3 as long as it passes through the front end of the surface gathered nonwoven fabric 21 forming the surface gather 20 or the vicinity thereof. Alternatively, it may be provided so as to extend on the liquid-permeable top sheet 3.
