Absorbent body 4 made of cotton-like pulp or synthetic pulp, etc., crepe paper 5 surrounding the absorbent body 4 for maintaining the shape and improving the diffusibility of the absorbent body 4, and substantially both side edges of the absorbent body 4 It is mainly comprised from the side nonwoven fabric 6 each arrange | positioned from the part to the side edge part of the said back surface sheet 2, and in the circumference | surroundings of the said absorber 4, the said liquid-impermeable back sheet 2 in the upper-lower-end edge part. And the liquid-permeable surface sheet 3 are bonded to each other by an adhesive such as hot melt or an adhesive means such as heat seal, and the both side edges of the liquid-permeable surface sheet 3 extend laterally from the absorbent body 4. Liquid back sheet 2 , And the side nonwoven fabric 6 are joined by adhesive means such as adhesive or heat sealing, such as a hot melt.

Hereinafter, specifically, the structure of the sanitary napkin 1 will be described in detail.
As the liquid-impervious back sheet 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.

  Next, as the liquid-permeable surface sheet 3, a porous or non-porous nonwoven fabric or a porous plastic sheet is preferably used. 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.

  In addition, when a large number of through holes are formed in the liquid-permeable surface sheet 3, menstrual blood, urine and the like (hereinafter collectively referred to as body fluid) are quickly absorbed, and the dry touch property is improved. It will be excellent.

  The absorbent body 4 is not particularly limited as long as it can absorb and retain body fluids, and piled pulp, airlaid, pulp nonwoven fabric and the like are used. In general, fluffy pulp mixed with water-absorbing polymer powder is preferably used from the viewpoint of absorption function and cost. As shown in the figure, the absorbent body 4 is preferably surrounded by crepe paper 5 for the purpose of shape retention and the like.

As shown in FIG. 1, the width dimension of the liquid-permeable surface sheet 3 is slightly longer than the width of the absorbent body 4, and only stops covering the absorbent body 4. Side nonwoven fabrics 6 are respectively disposed over the side edges of the back sheet 2. Specifically, the side nonwoven fabric 6 is made of a nonwoven fabric material that has been subjected to appropriate water-repellent treatment or hydrophilic treatment for the purpose of preventing permeation of menstrual blood, cages, etc., or enhancing the feeling of touch. It is configured using. The side nonwoven fabric 6 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 6 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.

(Embossed groove structure)
On the surface of the liquid-permeable surface sheet 3, longitudinal embossed grooves 7, 7 are formed in the crotch range S including the blood drainage site H along the substantially longitudinal direction in left and right pairs, and the napkin front side continuous to the crotch range S The napkin front side start ends of the vertical embossed grooves 7 and 7 are joined to the part F, and a convex front side width direction embossed groove 8 is formed on the napkin front end side, and the napkin continuous to the crotch range S is formed. Napkin rear end portions of the vertical embossed grooves 7 and 7 are joined to the rear portion B, and a convex rear width direction embossed groove 9 is formed on the rear end side of the napkin. A groove 11 is provided. Moreover, the area | region enclosed by the said embossing groove | channel 11 is the middle-high part 10 to which the absorber 4 was thickened, as FIG. 2 shows. The embossed groove 11 is formed such that the central portion P of the front width direction embossed groove 8 is positioned at the tip of the blood drainage port (small labia), and the longitudinal embossed grooves 7 and 7 are longitudinally formed. It is desirable that the blood drainage site H is located approximately in the center of the direction.

  In the present napkin 1, the vertical embossed grooves 7, 7 are formed in a shape that narrows the separation width from the napkin rear side to the front side. Therefore, even if the medium-high absorber 10 sandwiched between the longitudinal embossed grooves 7 and 7 can maintain a sufficient width on the rear side and receives pressure from the base portions of both legs as shown in FIG. Since the wrinkles and twists extend so as to escape to the front end side where the separation width is relatively narrow, wrinkles and twists are not easily generated on the rear side 12, and it is difficult for gaps to be formed between the body and the rear slant. It will be possible to prevent leakage from.

  It is desirable that the shape (width, length, gradient) of the vertical embossed grooves 7 and 7 is matched to the shape of the crotch of the body. Specifically, the directional embossed grooves 7 and 7 have a separation width FL of 20 to 40 mm, preferably 25 to 35 mm, and a separation width BL of the rear end of the napkin of 50 to 60 mm. desirable. When the separation width FL at the leading end of the napkin front side is less than 20 mm, it becomes less than the width of the blood drainage port and it is difficult to prevent leakage. If it exceeds 40 mm, the difference from the separation width BL at the rear end of the napkin becomes small and the inclination (gradient) of the longitudinal embossed grooves 7 and 7 becomes gentle, so that wrinkles and twists do not easily escape to the front end side. Wrinkles and twists will occur on the rear side 12. On the other hand, the dimension of the separation width BL at the rear end of the napkin is set as the width of the portion corresponding to the end of the blood drainage port of the average Japanese body type.

  The line width of the vertical embossed grooves 7, 7 is preferably 0.5 to 3.0 mm. If the line width is less than 0.5 mm, a clear embossed groove cannot be formed. If the line width exceeds 3.0 mm, the entire product is hardened and the wearing feeling is impaired.

  It is desirable that the vertical embossed grooves 7 and 7 are formed with curves that form a gentle convex shape toward the outside of the absorbent article in plan view. When pressure is applied from the leg portion, the absorbent body portion sandwiched between the longitudinal embossed grooves 7 and 7 is likely to rise to the surface side, and can easily bite into the blood outlet.

  As shown in FIG. 4, the embossed groove 11 is formed so that the embossed groove in the front region EF has a relatively high pressure squeezed portion rather than the low pressure squeezed portion. And it is desirable that the embossed groove in the rear region EB has a relatively larger amount of the low-pressure squeezed portion than the high-pressure squeezed portion than the vicinity of the rear end of the longitudinal embossed grooves 7 and 7. In the illustrated example, all the embossed grooves in the front region EF are high-pressure squeezed embosses 12a, and the embossed grooves in the rear region EB are alternately squeezed with high-pressure squeezed embosses 12a and low-pressure squeezed embosses 12b. The area of the emboss 12b is increased. In the front region EF, the absorbent bodies 4 and 10 are easily crushed by increasing the amount of the high-pressure portion relative to the low-pressure portion, whereas in the rear region EB, the pressure portion is relatively lower than the high-pressure portion. By increasing the number, the absorbers 4 and 10 are less likely to be crushed, eliminating wrinkles and twists from the back of the blood drain opening to the base of the buttocks so that no gap is formed between the body and the body. .

  As shown in FIG. 5, the rear side width direction embossed groove 9 has a substantially crescent shape in plan view, with the groove width being maximized at the center in the width direction and gradually narrowing toward the side. It can be an embossed groove. By forming the embossed groove having a substantially crescent shape in plan view, the embossing rigidity is increased in the central part, and the embossing rigidity is gradually decreased toward the side part. You can make it difficult to twist. In this case, as shown in FIG. 6 (A), the high-pressure portion 2a may be formed over the entire length of the groove, but as shown in FIG. In order to make it hard to generate | occur | produce, you may make it form along a groove width direction, putting the low pressing part 12b in the middle.

  On the other hand, in the absorbent body 4, as shown in FIG. 7, a concave emboss groove 13 may be formed along the longitudinal direction of the napkin at the substantially center position of the vertical emboss grooves 7 and 7 on the back surface side. Is possible. The concave embossed groove 13 has a concave groove shaft portion thinner than the other portions, and the rigidity (second moment of cross section) is reduced, so that the concave embossed groove 13 is a flexible shaft (longitudinal flexible shaft). Transformability in the transverse direction is ensured, and in the mounted state, the flexible shaft portion is deformed so as to be bent in the transverse direction, so that the body fits along the roundness of the buttocks and the flexible Since the absorber is deformed so as to be raised by the shaft, it can be brought into close contact with the recessed portion of the buttocks.

[Other examples]
