Description

  The present invention relates to absorbent articles such as sanitary napkins, panty liners, incontinence pads and the like for absorbing menstrual blood and vaginal discharge, and more particularly to an absorbent article that improves adhesion to the body and eliminates post-leakage.

  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.

  Numerous improvements have been made on 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 of forming a concave groove by hot embossing together with the middle and high portions of the absorber. For example, in Patent Document 1 described below, a body fluid is obtained by compressing and deforming a pulp with fit embossing in the shape of a medium-high shape, and forming a middle-high portion by providing a leak-proof groove around the middle-high portion. A technique for preventing the diffusion (leakage) of the liquid has been proposed.

  Moreover, in the following Patent Document 2, a liquid permeable layer is provided on the skin contact surface side, a liquid impermeable layer is provided on the non-skin contact surface side, and an absorbing portion interposed between the liquid permeable layer and the liquid impermeable layer. In the absorbent article that is formed substantially vertically, the central part of the absorbent part is provided with a raised part extending in the longitudinal direction of the absorbent article raised to the skin contact surface side. An absorbent article having one or more grooves extending in the longitudinal direction of the absorbent article is disclosed on the non-skin contact surface side of the absorbent part corresponding to the part.

  Further, in Patent Document 3 below, an absorption element that receives and holds body fluid from the use surface side, a leakage prevention sheet that prevents the leakage of body fluid from the absorption element to the back surface side on the back side, and at least In the middle of the product in the longitudinal direction, it has elastic elastic members for the gathered cuff sheet that is on both sides of the product and does not substantially allow permeation of body fluids, and is used by the contraction force of the elastic elastic members when the product is installed Gather cuffs standing on the skin of the person, the absorbent element straddles the blood drainage site along the longitudinal direction, and has a middle and high part with a high use surface in the widthwise center part, The gather cuff is configured so that its contractile force acts at least in a length range corresponding to a range straddling the blood outlet site, and a length range straddling at least the blood outlet site on both sides of the middle and high parts of the absorption element garden What embossed is formed, these embossments, sanitary napkin has a shape that bulges outward in the width direction than the front and rear in Haichiguchi sites have been proposed.

Furthermore, in the following Patent Document 4, as shown in FIG. 5, a pair of embossed grooves 50, 50 are formed on both sides of the mid-high portion absorber, and the embossed grooves are directed outward in the width direction of the napkin. There has been proposed a sanitary napkin in which convexly curved portions 51a to 51c have a shape in which three in the longitudinal direction of the napkin are connected, and a convexly curved portion 51b located in the middle corresponds to the excretory region.
JP-A-11-33054 JP 10-328232 A JP 2001-95842 A JP 2008-79747 A

  The inventions described in Patent Documents 1 to 3 described above all eliminate leakage of menstrual blood and the like by fitting the absorber in accordance with the body shape of the blood drainage site. Even if it is possible to make almost close contact, the fit to the part of the valley of the rupture part on the back side from the end of the vaginal opening is insufficient, and leakage through the groove of the rupture part is surely prevented. I couldn't.

  Further, the embossed groove 50 described in the cited document 4 is a constricted portion in which the joint portion of each curved portion narrows the emboss interval, and this constricted portion is formed on the front side and the rear side across the excretory region. In addition, since the constricted portion serves as a folding start point when the napkin is bent in the longitudinal direction, it is easy to follow the curved shape of the body as a whole. Moreover, when each curved part 51a-51c receives the side pressure F from the base of a foot, the part with the large width | variety between pressing grooves will receive a big compressive force, and the absorber of this part is more than other parts. Raises to the skin side.

  However, especially when assuming the case of sleeping on the back with the night napkin attached, the adhesion at the rupture part on the rear side of the body fluid excretion part is still insufficient, and the rear leakage from the rear side is surely eliminated. It is not possible.

  Then, the main subject of this invention is providing the absorbent article which raised the adhesiveness with respect to the groove | channel of a bodily fluid discharge port and a crack part, and prevented back leak reliably.

While having two constricted parts consisting of the first constricted part and the second constricted part, the body fluid discharge part is located on the front side of these two constricted parts, and the width between the compressed grooves extends from the cracked part to the rear part side. An absorbent article is provided that is shaped to progressively shrink.

  In the first aspect of the present invention, a pair of left and right pressing grooves extending substantially in the longitudinal direction of the absorbent article are formed on both sides of the liquid-permeable surface sheet, and the pressing grooves are spaced in the longitudinal direction of the absorbent article. While it has two constricted parts which consist of the 1st constricted part and the 2nd constricted part which narrowed the width | variety between pressing grooves, the bodily fluid discharge part is located in front of these two constricted parts.

  The first constricted portion and the second constricted portion serve as folding points when the absorbent article is curved along the longitudinal direction, and are easily deformed in a form along the body shape as a whole. Moreover, in this invention, it has a said 1st narrow part and a 2nd narrow part on the back side of a bodily fluid discharge part. When receiving a lateral pressure from the base of the foot, a portion where the width between the compressed grooves is large, that is, a portion other than the first constricted portion and the second constricted portion is subjected to a large compressive force so as to rise more than the other portions. Become. Specifically, the body fluid discharge portion is raised, and two raised portions are formed on the rear side from this. Therefore, the body fluid discharge part is in close contact with the blood outlet, and the two raised parts come into close contact with the groove of the rupture part, so that menstrual blood or the like leaks after passing through the groove of the rupture part. Can be prevented.

  As a second aspect of the present invention, the first constricted portion close to the body fluid discharge portion of the two constricted portions is located at the substantially rear end of the vaginal opening, and the second constricted portion located on the rear side is a rupture. The absorbent article according to claim 1, which is located at a substantially deepest part of the groove of the part.

  According to the second aspect of the present invention, of the two constricted portions, the first constricted portion close to the body fluid discharge portion side is located at the substantially rear end of the vaginal opening, and the second constricted portion located on the rear side is a rupture. It is made to be located at the substantially deepest part of the groove of the part. Since the constricted portion rises with a narrower width than the other portions, the first constricted portion close to the body fluid discharge portion side is located at the substantially rear end of the vaginal opening, and the second constricted portion located on the rear side is By locating at the substantially deepest part of the groove of the cracked part, it is possible to more effectively prevent menstrual blood and the like from leaking through the groove of the cracked part.

  As a third aspect of the present invention, the first constricted portion is located 28 mm ± 10 mm away from the center point of the body fluid discharge portion, and the second constricted portion is 85 mm ± 10 mm away from the center point of the body fluid discharge portion. An absorbent article according to any one of claims 1 and 2 is provided.

  The invention according to the third aspect numerically defines the positions of the first constricted portion and the second constricted portion limited by the invention according to the second aspect.

  The absorption according to any one of claims 1 to 3, wherein as the present invention according to claim 4, the compressed groove is formed such that the width between the compressed grooves gradually decreases from the rear side to the rear side of the cracked portion. A sex article is provided.

  In the invention according to claim 4, the compressed groove is formed so that the width between the compressed grooves gradually decreases from the rear side to the rear side of the cracked portion, so that the groove on the end side of the cracked portion is compared with the groove. This makes it easier for the absorber to fit and prevents transmission leakage.

  According to a fifth aspect of the present invention, the absorber has a middle-high portion that protrudes to the surface side, and a rear-side edge of the middle-high portion is located on the front side of the second constricted portion located on the rear side. An absorbent article according to any one of claims 2 to 4 is provided.

  In the invention according to claim 5, the absorber has a middle-high portion protruding to the surface side, and a rear-side edge of the middle-high portion is located on the front side of the second constricted portion located on the rear side. Is. On the rear side of the absorbent article, since it is a part that is not significantly affected by the side pressure from the base of the foot, it is preferable to reduce the rigidity of the absorbent body so that it can be easily deformed along the shape of the groove. .

  As the present invention according to claim 6, there is provided the absorbent article according to claim 5, wherein a side edge of the middle and high part is located inwardly from the pair of left and right pressing grooves.

  In the invention according to the sixth aspect, when the side pressure is applied, a middle space portion absorber is more likely to rise to the skin surface side by providing a certain interval between the side edge of the middle height portion and the pressing groove.

  As described above in detail, according to the present invention, it is possible to improve the adhesion to the body fluid discharge port and the groove of the rupture portion, thereby reliably preventing the back leak.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
[Basic structure of sanitary napkin 1]
1 is a partially broken development view of a sanitary napkin 1 according to the present invention, and FIG. 2 is a view taken along the line II-II in FIG.

  The sanitary napkin 1 includes a liquid-impervious back sheet 2 made of a polyethylene sheet, a polypropylene sheet, etc., a liquid-permeable front sheet 3 that allows permeation of menstrual blood, cages, and the like, and a space between the two sheets 2 and 3. An absorbent body 4 made of cotton-like pulp or synthetic pulp intervening in the sheet, crepe paper 5 surrounding the absorbent body 4 for maintaining the shape and improving the diffusibility of the absorbent body 4, and longitudinally on both sides of the surface. It is comprised from the side nonwoven fabrics 7 and 7 formed along the 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 F 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. 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.

  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 said absorber 4 is equipped with 4A of middle-high part absorbers which protruded to the skin surface side in the width direction center part.

  Moreover, you may mix a synthetic fiber with the said absorber 4 and the middle-high part absorber 4A. 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.

  As in this example, when the crepe paper 5 surrounding the absorbent bodies 4 and 4A is provided, as a result, the crepe paper 5 is interposed between the liquid-permeable surface sheet 3 and the absorbent body 4, The crepe paper 5 having excellent absorbability rapidly diffuses body fluid and prevents reversal of these menstrual blood and the like. In particular, in the present invention, as described in detail later, one of the objects is to reduce the uncomfortable feeling when the napkin is mounted, and therefore the thickness of the middle and high part 4A site (including the absorber 4) is 4.5 to The thickness of the absorbent body 4 (peripheral part) is preferably in the range of 2.2 to 4.2 mm, and the manufacturing method of the absorbent body 4 is a piled fiber so as to be rich in flexibility. An airlaid absorber is preferred. In addition, although not shown in figure, the absorber 4 is good also as a middle-high structure where the blood-evacuation port corresponding | compatible part swelled.

  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.

[Structure of compressed grooves 8, 8]
In this sanitary napkin 1, as shown in detail in FIG. 3, a pair of left and right squeezing grooves 8 and 8 (hereinafter referred to as side squeezing) extending substantially in the longitudinal direction of the napkin 1 on both sides of the liquid-permeable surface sheet 3 as shown in FIG. Also called a groove). The side squeezing grooves 8, 8 are coupled to each other on the front side by the front end coupling squeezing groove 9 and are coupled at the rear end by the rear end coupling squeezing groove 10, thereby closing the circumferential direction as a whole. is doing. In addition, these pressing grooves 8-10 can be provided by arbitrary means such as embossing by heat and / or pressure, ultrasonic waves, or a combination thereof. Moreover, 4A of middle-high part absorbers are formed in the inside of the pressing grooves 8-10 closed in the said circumferential direction.

Hereinafter, the pressing grooves 8 to 10 will be described in detail based on FIG.
The front end combined pressing groove 9 is a pressing groove formed in a substantially semicircular arc shape, and includes a pair of left and right side pressing grooves 8, 8 along a substantially longitudinal direction respectively formed on both sides of the middle and high portion absorber 4A. It is a squeezing groove joined by an arcuate curved line at the front end of the napkin.

  The rear end combined pressing groove 10 is also a pressing groove formed in a substantially semicircular arc shape, and a pair of left and right side pressing grooves 8, 8 along the substantially longitudinal direction respectively formed on both sides of the middle / high portion absorber 4A. Is a squeezing groove that joins arcuate curved lines at the rear end of the napkin.

  The side squeezing grooves 8 and 8 are squeezing grooves extending in the longitudinal direction and formed in a range from a substantially front end portion of the vaginal opening to a substantially ending point of the cracked portion, and are spaced apart in the longitudinal direction of the napkin 1. While having the two constricted parts 11 and 12 which consist of the 1st constricted part 11 and the 2nd constricted part 12 which narrowed the width | variety between the pressing grooves 8 and 8, body fluid discharge | emission is ahead of these two constricted parts 11 and 12 The portion H is located, and the width between the compressed grooves 8 and 8 is gradually reduced from the cracked portion to the rear side.

  As a result, in the front and rear portions of the first constricted portions 11 and 12, there are relatively wide portions between the compressed grooves 8 and 8, respectively. The front side of the first constricted portion 11 is the first widened portion 13, the rear side is the second widened portion 14, and the rear side of the second constricted portion is the third widened portion 15.

Of the two constricted portions 11 and 12, the first constricted portion 11 close to the body fluid discharge portion H side is located at the substantially rear end of the vaginal opening K, and the second constricted portion 12 located on the rear side is the rupture portion. It is desirable to be located at the substantially deepest part of the groove. Specifically, the first constricted portion 11 is located 28 mm ± 10 mm (L ₁ ) away from the center point of the body fluid discharge portion H, and the second constriction portion 12 is the center point of the body fluid discharge portion H. It is desirable to be located at a distance of 85 mm ± 10 mm (L ₂ ).

  Accordingly, the two constricted portions 11 and 12 serve as folding points when the napkin 1 is curved along the longitudinal direction, and are easily deformed along the body shape as a whole. The two constricted portions 11 and 12 are located on the rear side of the body fluid discharge portion H, that is, the presence of the two folding points makes it easier for absorbed menstrual blood and the like to be absorbed, and rear leakage is effective. Will be prevented.

  Further, as shown in FIG. 3, when a compressive force F, F... Is received from both sides toward the longitudinal direction center side of the napkin 1 from the base of the foot to the cracked portion and the rear end side, In each part of the 1st-3rd wide part 13-15 in which the width | variety between 8 and 8 was expanded, it will receive larger compressive force than the said constriction parts 11 and 12, and the absorber 4 is more than other parts. Also rises to the skin side. Accordingly, the first widened portion 13 including the body fluid discharge portion H is in close contact with the blood outlet, and the two second widened portions 14 and the third widened portion 15 are in close contact with the groove of the rupture portion. Therefore, menstrual blood or the like can be prevented from leaking through the groove of the rupture portion.

  Moreover, the said side pressing grooves 8 and 8 are formed so that the width | variety between pressing grooves may reduce gradually from the rear part side of a crack part to the rear side. Therefore, the valley is broken at the broken line indicated by the dotted line C, and it is easy to fit into the groove of the cracked portion.

Here, the width of the side pressing grooves 8, 8 is as follows when specifically expressed by suitable numerical values.
The maximum width _{B 1} of the first widened portion 13, 46~56mm, the width _{B 2} of the first constricted portion includes 42～54Mm, the maximum width _{B 3} of the second widened portion 14 46～57Mm, the width of the second constricted portion B ₄ is 33～45Mm, the maximum width _{B 5} of the third widened portion 15 is a 43～53Mm. Further, the relative difference (B ₁ -B ₂ ) between the maximum width B ₁ of the first widened portion 13 and the width B ₂ of the first constricted portion is 2 to 4 mm, and the maximum width B of the second widened portion 14. ₃ and the width B ₂ of the first constricted portion (B ₃ −B ₂ ) is 3 to 4 mm, and the relative difference between the maximum width B ₃ of the second widened portion 14 and the width B ₄ of the second constricted portion _(B 3 -B ₄₎ is 10～13Mm, the relative difference between the maximum width _{B 5} of the third widened portion 15 and the second constricted portion width _{B 4} of _(B 5 -B ₄₎ is that the 8~10mm desirable.

  On the other hand, as shown in FIG. 1, with respect to the middle-high portion absorber 4A, it is desirable that the rear side edge of the middle-high portion absorber 4A is located in front of the second constricted portion 12 located on the rear side. . On the rear side of the napkin 1, since it is a part that is not significantly affected by the side pressure from the base of the foot, the rigidity of the absorbers 4 and 4A is reduced, and the second constricted part 12 is easily bent into a curved shape so that the grooves It is rather desirable to make it easy to deform along the shape. Moreover, it is desirable that the side edge of the middle-high portion absorber 4A is located at a position spaced inward from the pair of left and right pressing grooves 8, 8. By providing a certain distance between the side edge of the middle and high part 4A and the compressed grooves 8 and 8, when the side pressures F and F act, the middle and high part absorber 4A is more likely to rise to the skin surface side. Furthermore, if the medium and high part absorber 4A is added so as to interspersed with dot-like embosses, the density of the medium and high part absorber 4A increases and the hardness comes out. It comes to bulge to the skin side more, and fit property improves.
