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 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 It is mainly composed of a pair of left and right three-dimensional gathers BS, BS provided on the surface side in a predetermined section in the front-rear direction so that the side edge portion is an upright base end and includes at least the body fluid discharge portion R, In the periphery of the absorbent body 4, the outer edge portions of the liquid-impervious backsheet 2 and the liquid-permeable topsheet 3 are used as adhesives such as hot melt and adhesive means such as heat seal at the upper and lower end edges. By The liquid-impervious backsheet 2 that is joined and extends laterally from the absorbent body 4 at both side edges and the side nonwoven fabric 7 that forms the three-dimensional gather BS are bonded by hot melt or the like. Wing-like flaps W and W that are joined by adhesive means such as an agent and 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. Also, second wing-shaped flaps (hip hold flaps) W _B and W _B are formed in a portion located on the buttocks 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. 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. 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.

  On the use surface side of the absorbent body 4, there is a middle height portion 6 of the absorbent body that is high on the use surface side in a region defined by an emboss 8 elongated in the longitudinal direction of the napkin and closed in the circumferential direction at the center in the width direction. Is formed. 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. Moreover, the embossing 9 and 10 are formed in the use surface side with the said embossing 8, respectively.

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 R. 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, W, respectively on the outer surface side adhesive layer 12 of the _B ..., 13 ... comprises a, when worn for shorts, the wing-shaped flaps W, W are folded line It is folded back to the opposite side at the RL position and wrapped around the crotch portion of the shorts to be 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 26, and a plurality of, in the illustrated example, two thread-like elastic stretch members 27, 27 are fixed at both ends or at appropriate positions in the longitudinal direction at the upper portion of the thread-like elastic stretch member 26. 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 bonded to the absorbent body 4 side, so that the portion where the thread-like elastic elastic member 26 is disposed is arranged. As the bending points, three-dimensional gathers BS and BS standing on the surface side are formed while forming pocket spaces P and P with openings inward in a cross-sectional shape.

[Pocket sheet structure]
As shown in FIG. 1 and the like, a pocket space P _B opened to the body fluid discharge portion R side is formed in the rear portion of the sanitary napkin 1 so as to cover the upper surface side of the liquid-permeable surface sheet 3. A pocket sheet 14 is provided. In the illustrated example, the pocket sheet 14 has a shape dimension defined by a peripheral side outline 14a that coincides with the outline of the rear portion of the sanitary napkin 1 and an opening side outline 14b that crosses the napkin width direction. Is done. The position of the opening-side outline 14b prevents the body fluid that has flowed to the rear side from crossing over the portion where the side nonwoven fabric 7 is folded in a Z-shaped cross section (the non-standing portion of the three-dimensional gather BS) and leaking laterally. to, terminating near the upright section of the standing gather BS (near the rear end), specifically 20 mm ± from termination position of the standing section of the standing gathers BS, as preferably located within a range of ± 10 mm It is desirable to do.

The bonded area of said pocket sheet 14, the periphery so as to form a pocket space P _B only needs to be bonded to the napkin (hatched range). In the illustrated example, both end portions in the width direction of the pocket sheet 14 are bonded to the upper surface of the side flap (second wing-shaped flap W _B ) located outward from the absorbent body 4, and the second wing-shaped flap W _B. Standing up from above. Further, the rear side middle portion of said pocket sheet 14 is adapted to stand from the upper surface of the substantially absorbent body 4.

The pocket space P _B can be completely contained so that the captured body fluid does not flow outside. However, if the speed at which the captured body fluid flows out is reduced, the absorber 4 Therefore, as the material of the pocket sheet 14, any sheet material other than the water-permeable sheet that completely loses the capturing function as the pocket space P _B can be used.

Specifically, (1) a sheet material having an absorptivity, for example, a non-woven fabric using a fiber having water absorbency, a non-woven fabric subjected to a hydrophilic treatment, and further, the absorptive material is laminated on a plastic film. A multilayer sheet or the like can be used. In this case, examples of the absorbent material include airlaid absorbers, thin SAP sheets mixed with a large amount of highly water-absorbent resin, and the like. Moreover, you may make it laminate | stack an opening film so that the said absorptive material may be covered. (2) A nonwoven fabric having a slight water permeability, for example, a nonwoven fabric using polyolefin fibers, a water repellent treated nonwoven fabric subjected to a water repellent treatment, and the like can be used. (3) A sheet material having water barrier properties such as a plastic film or a laminated nonwoven fabric can be used. In particular, when a laminated nonwoven fabric is used, by placing the nonwoven fabric surface side as the skin surface side and the plastic film side as the absorption surface side, the touch is good and the leak-proof property is improved. In this case, the nonwoven fabric may be either hydrophilic or water-repellent, but is preferably a hydrophilic nonwoven fabric having water absorption. The plastic film may be a non-breathable film or a breathable film when used alone or in a laminated nonwoven fabric, but a breathable film may be used to improve stuffiness. It is desirable to use it.

The pocket sheet 14 includes the pocket space P _B 1 Article opening for resilient and elastic members 15 disposed along the napkin longitudinally widthwise center in order to open the. The elastic elastic member for opening 15 has one end side extended to a region (hatched area) reaching the bonding region of the pocket sheet 14, and the other end side preferably extended to a position near the opening side outline 14b of the pocket sheet 14. As shown in FIGS. 3 and 4, the opening side outline 14 b side of the pocket sheet 14 is raised by the action of the elastic stretching force along the longitudinal direction of the napkin, and the pocket space P _B Open. Therefore, the body fluid leaking later can be reliably captured without overflowing from the upper surface of the pocket sheet 14.

  As shown in FIG. 5 (A), the elastic elastic member for opening 15 is arranged such that a small folded portion 14c is formed in the central portion of the pocket sheet 14, and the elastic elastic member for opening is formed between the folded portions 14c.
