Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to absorbent articles such as sanitary napkins, panty liners, incontinence pads, etc., for absorbing menstrual blood and vaginal discharge. More specifically, a large amount of body fluid is instantaneously discharged. The present invention relates to an absorbent article that retains and absorbs this bodily fluid so as to prevent the body fluid from leaking and a method for manufacturing the absorbent article.

[0002]

2. Description of the Related Art Conventionally, as absorbent articles such as panty liners, sanitary napkins and incontinence pads, liquid impermeable back sheets such as polyethylene sheets or polyethylene sheet laminated nonwoven fabrics and nonwoven fabrics or liquid permeable plastic sheets etc. It is known that an absorbent body made of cotton-like pulp or the like is interposed between the liquid-permeable top sheet and the liquid-permeable top sheet.

Many improvements have been made to this type of absorbent article, and various measures have been taken to prevent body fluid leakage. As one of these body fluid leakage prevention means, there is a technique of forming a concave groove by hot embossing. For example, in Japanese Laid-Open Patent Publication No. 11-33054, the absorbent body that is uniformly laminated is squeezed and deformed to form a middle high portion with a fit embossing having a middle height shape, and a leak-proof groove is provided around the middle high portion. Therefore, a technique for preventing the diffusion (leakage) of body fluids has been proposed, and in JP-A-9-108262, a bottom surface is formed on the upper surface of the sanitary napkin by a planar shape that extends in the longitudinal direction and has a narrow interval in the central portion. There has been proposed a technique for forming a pair of left and right compressed groove portions each having a high-pressure pressed portion and a low-pressure pressed portion alternately.

[0004]

However, the above-mentioned function of the concave groove is only to prevent further diffusion by allowing the body fluid flowing along the surface of the liquid permeable top sheet to flow into the concave groove. However, when a large amount of body fluid or the like is instantaneously discharged, the body fluid is not held and absorbed so as not to leak. That is, the amount of bodily fluid discharged varies from time to time, and a large amount of bodily fluid may be instantaneously discharged or may be discharged little by little. Therefore, when a large amount of bodily fluid is instantaneously discharged, it is not sufficient to simply block the concave groove to prevent further diffusion, and it is not enough to prevent the diffusion of the bodily fluid to the absorber in the concave groove. It must have sufficient shape characteristics for holding and absorbing.

Therefore, the main object of the present invention is to regulate the formation conditions, shape characteristics, etc. of the groove-shaped embossing so that even if a large amount of body fluid is instantaneously discharged, this body fluid is retained so as not to leak. -To provide an absorbent article designed to absorb.

[0006]

According to a first aspect of the present invention for solving the above problems, there is provided an absorbent material having an absorbent body interposed between a liquid permeable top sheet and a liquid impermeable back sheet. In the article, there is a groove-shaped center emboss provided on the absorbent body from the upper surface of the liquid-permeable top sheet over the range including the blood drainage site on the center line of the absorbent article in the longitudinal direction. An absorbent article is provided, in which side embossments provided from the upper surface of the liquid-permeable top sheet are also present on both sides of the center emboss along the longitudinal direction of the absorbent article.

In the invention according to claim 1, the side embossing is formed together with the center embossing on the surface side of the absorbent article. The function of this side embossing is retained because it exceeds the allowable amount of the center embossing by any chance.
When there is body fluid that cannot be absorbed, it is of course possible to prevent the further diffusion by causing the body fluid portion overflowing from the center emboss to flow into the concave groove of the side emboss, but it is also formed with the center emboss. By doing so, it is formed in order to improve the body fluid permeability of the liquid-permeable top sheet in the center embossing. That is, by forming the side embossing, the liquid-permeable top sheet is completely fixed and constrained to the absorber at the side embossing position, and the liquid-permeable top sheet is held in a stretched state. On the other hand, in the center embossed portion, since the concave groove is formed while the liquid-permeable top sheet is stretched, in the case of a top sheet having a large number of openings, the diameter of the openings is enlarged by stretching, and In the case of a non-woven fabric, the gap between the fibers is expanded, so that the liquid permeability (permeation speed) is improved and the body fluid flowing into the center emboss is quickly absorbed by the absorber. Since the openings other than the center embossed portion are the same as before, the feeling of touch and the like do not deteriorate.

Then, claim 2 of a concrete and preferred embodiment

When the medium-high absorbent body is provided, it becomes easy to form a deeper concave groove as the center embossing, and the absorbent body between the side embossing adjacent to both sides exhibits a bulge like a bulge. Therefore, the flow of body fluid into the recessed groove of the center emboss is promoted, and the opening of the top sheet or the fiber gap of the non-woven fabric is further expanded in the center embossed portion, so that liquid permeability (permeation) Speed) will be further increased.

The present invention according to claim 3 provides the absorbent article according to any one of claims 1 and 2, wherein the center emboss is formed over a length range of 50 to 100 mm.

Absorbers 6 made of cotton-like pulp or synthetic pulp interposed between the absorbers, crepe paper 5 surrounding the absorber 4 in order to maintain the shape of the absorber 4 and improve diffusibility; and the absorber. 4 is a standing base end, and is mainly composed of a pair of left and right three-dimensional gathers BS and BS which are provided at least projecting from the blood outlet corresponding portion in the front-rear direction in a predetermined section in the front-rear direction. Further, in the periphery of the absorber 4, the outer edges of the liquid-impermeable back sheet 2 and the liquid-permeable top sheet 3 at the upper and lower edges thereof are an adhesive such as hot melt or an adhesive means such as heat seal. Therefore, the liquid-impermeable backsheet 2 which is joined and extends laterally beyond the absorber 4 at both side edges thereof and the side nonwoven fabric 7 forming the three-dimensional gather BS are made of hot melt or the like. The wing-shaped flaps W, W, which are joined together by an adhesive means such as an adhesive or heat seal, and which project laterally are formed by the laminated sheet portion of the liquid-impermeable back sheet 2 and the side nonwoven fabric 7, The buttock-side wing-shaped flaps W _B , W _B are formed in the portion located on the back side of the buttock.

The structure of the sanitary napkin 1A will be described below in more detail.
As the material, a sheet material having at least water-blocking property such as polyethylene is used, but in recent years, a material having moisture permeability tends to be used from the viewpoint of preventing stuffiness. This water-impermeable / moisture-permeable sheet material is obtained by melt-kneading an inorganic filler in an olefin resin such as polyethylene or polypropylene to form a sheet, and then stretching the sheet uniaxially or biaxially A sheet is preferably used. One or a plurality of adhesive layers (not shown) are formed on the non-use surface side (outer surface) of the liquid-impervious back sheet 2 so that the sanitary napkin 1A is fixed to the underwear when worn on the body. It has become.

Next, as the liquid-permeable top sheet 3, a perforated or non-perforated nonwoven fabric, a porous plastic sheet or the like is preferably used. As the material fibers constituting the non-woven fabric, in addition to synthetic fibers such as olefins such as polyethylene or polypropylene, polyesters, polyamides, etc.,
Regenerated fibers such as rayon and cupra, and natural fibers such as cotton can be used, and a nonwoven fabric obtained by an appropriate processing method such as a spunlace method, a spunbond method, a thermal bond method, a meltblown method, or a needle punch method is used. be able to. Among these processing methods, the spunlace method is excellent in flexibility and drapability, and the thermal bond method is excellent in bulkiness and softness. When a large number of through holes are formed in the liquid permeable top sheet 3, menstrual blood, scents and the like (hereinafter collectively referred to as body fluids) are quickly absorbed, and the dry touch property is excellent. Will be things.

The absorbent body 4 may be any one capable of absorbing and retaining body fluid. Usually, fluffy pulp mixed with water-absorbing polymer powder is preferably used from the viewpoint of absorbing function and price. It The absorber 4 is preferably surrounded by a crepe paper 5 to maintain its shape.

A medium-high absorbent body 6 is arranged in the central portion on the upper surface side of the absorbent body 4 along the longitudinal direction. The thickness of the medium-high absorbent body 6 is preferably 5 to 20 mm, and more preferably 10 to 15 mm, because the rigidity of the absorbent body increases and the adhesion to the body decreases if it is made too thick.

On the surface of the liquid-permeable top sheet 3, the medium-high absorbent body 6 is held in a predetermined position, swelled firmly to the surface side, and the absorbed body fluid is contained. The middle-high part definition embossing 13 is formed from the upper surface side of the liquid permeable top sheet 3 so as to surround the periphery. The middle-high part defining embossment 13 includes a front end semi-circular arc-shaped embossed portion 13a and a side embossed portion 13b extended from both ends of the front end semi-circular arc-shaped embossed portion 13a to a rear end side along a substantially longitudinal direction. , 13b,
In the illustrated example, the side embossments 13b and 13b are closed on the rear end side. In addition, among these middle-high part definition embosses 13, what constitutes the “side emboss” in the present invention is the side embosses 13 b, 13 described above.
It is part b.

Further, a horseshoe-shaped front side embossing 12 is formed at the front end of the absorbent body 4, and a gentle arc shape bulging toward the inner side is formed on the side portion of the middle-high part defining embossment 13. Second side embosses 14, 14 that draw a line are formed.

On the other hand, in the illustrated example, the width dimension of the liquid permeable top sheet 3 is set to be slightly longer than the width of the absorbent body 4 as shown in the transverse sectional views of FIGS. Four
The three-dimensional gather BS prevents the side non-woven fabric 7 different from the liquid permeable top sheet 3, specifically, menstrual blood, a stuff, etc. from permeating, or enhances the feeling of touch. According to the purpose, the non-woven fabric material is appropriately treated to be water repellent or hydrophilic. The side nonwoven fabric 7 may be made of natural fibers, synthetic fibers, regenerated fibers, or the like and is formed by an appropriate processing method. However, it is preferable to eliminate the stickiness and prevent stuffiness. Therefore, it is preferable to use a non-woven fabric having a low basis weight and breathability. Specifically, it is desirable to use a non-woven fabric made with a basis weight of 18 to 23 g / m ² , and to reliably prevent permeation of body fluids, silicone-based, paraffin-based, alkylchromic chloride-based water repellents, etc. A water repellent non-woven fabric coated with is preferably used.

As shown in FIG. 2 and FIG. 3, the side nonwoven fabric 7 has an absorbent body 4 on the outer side from the widthwise middle portion.
The side non-woven fabric 7 and the liquid impermeable back sheet 2 are bonded to each other with an adhesive such as hot melt over a range from the inner position of the absorbent body slightly beyond the side edge of the absorber to the outer edge of the liquid impermeable back sheet 2. the laminated sheet portions of the substantially horizontally to the absorption body side unit position corresponding to the fluid outlet pair of wing flaps W, to form a W, which from the second wing-shaped flaps W _B, and W _B are formed on the buttocks side position ing. These wing-shaped flaps W, W and second wing-shaped flaps W _B, respectively adhesive layer 10 ... on the outer surface side of the W _B, 11 ... comprises a, as shown in FIG. 8, when worn against shorts 30, folded At the line RL position, it is folded back to the other side and wrapped around the crotch part of the shorts to be fastened.

On the other hand, the inner portion of the side nonwoven fabric 7 is folded back in a substantially double manner, and inside the double sheet, a thread-like elasticity whose both ends or appropriate positions in the longitudinal direction are fixed to the middle portion in the height direction. The elastic member 19 is disposed, and a plurality of, in the illustrated example, two elastic elastic members 20, 20 are fixed at the upper side of the elastic elastic member 19 at both ends or at appropriate positions in the longitudinal direction. It is arranged in the state. As shown in FIG. 3, the double sheet portion is attached to the absorbent core 4 side in a state where the double sheet portion is folded and laminated in a Z-shaped cross-section as shown in FIG. As bending points, three-dimensional gathers BS, BS standing upright on the surface side are formed while forming pockets P, P having an opening facing inward in a V-shaped cross section.

In the sanitary napkin 1A, a groove is formed from the upper surface of the liquid permeable top sheet 3 to the middle-high absorbent body 6 particularly on the center line of the sanitary napkin 1A in the longitudinal direction and in the range including the blood drainage site. A center-shaped emboss 8 is formed. The side embossments 13b, 13b of the middle-high section definition embossing 13 described above are arranged on the sides of the center embossing 8 according to the present invention.

The center emboss 8 preferably has a longitudinal dimension L of 50 to 100 mm and a groove bottom width B of 2 to 7 mm.
It is preferably 3 to 5 mm. It is desirable that the maximum depth H of the groove is 3 mm or more and 15 mm or less, preferably 10 mm or less, and the volume of the groove is 0.5 cm ³ or more.

When the longitudinal dimension L is less than 50 mm,
The blood drainage part of the body may be displaced from the center emboss 8 due to the position shift of the napkin at the time of wearing, or the position may be largely deviated to the front and rear end side, and sufficient body fluid retention may be achieved due to the relative positional relationship with the blood drainage part. It becomes impossible to form a space. Further, when the longitudinal dimension L exceeds 100 mm, the body fluid holding space is sufficiently formed, but the rigidity of the absorbent body is excessively increased, resulting in poor fitability.

If the width B of the bottom of the groove is less than 2 mm, a groove having a sufficiently open upper surface cannot be formed and the inflow of body fluid is hindered. The bottom width B of the groove is 7 mm
When it exceeds, the rigidity of the absorbers 4 and 6 becomes too high and the fit to the body is deteriorated.

Further, when the groove depth H is less than 3 mm, a sufficient body fluid inflow space is not secured, and when the groove depth H exceeds 15 mm, the liquid permeable top sheet 3 is stretched by embossing. This causes problems such as breakage. Finally, when the volume of the concave groove is less than 0.5 cm ³ , body fluid rarely overflows from the concave groove.

Center embossed 8 processed portion (groove wall portion)
Then, since the concave groove is formed while the liquid-permeable top sheet 3 is stretched, in the case of a top sheet having a large number of openings, the diameter of the openings is enlarged by stretching,
Further, in the case of a non-woven fabric, the gap between the fibers is expanded, so that the liquid permeability (permeation rate) is improved and the body fluid flowing into the center emboss 8 is quickly absorbed by the absorber. If the liquid-permeable top sheet 3 is a porous plastic sheet, the pore diameter of the porous plastic sheet stretched by the center emboss 8 is 110 to 300%, preferably 150 to 2 as compared with the surroundings.
It is desirable to set it to 00%.

The concave groove formed by the center emboss 8 is
As shown in FIG. 4, it may be formed with a constant depth H from the front end portion to the rear end portion, but preferably, as shown in FIG. 5, the groove depth of the middle portion is set to the deepest, It is preferable that the groove bottoms of the front side portion and the rear side portion adjacent to the intermediate portion are formed as inclined bottoms inclined toward the intermediate portion. This makes it possible to control the flow direction of the body fluid that has flowed into the concave groove to some extent, and more reliably prevent leakage in the front-rear direction.

By the way, during the process of manufacturing the sanitary napkin 1A, the process of applying the center emboss 8 is as follows.
It is desirable to perform it after performing the imparting process of the embossing 13 for middle and high section definition. The side embossments 13b, 13b located first on the side where the center embossment 8 is to be formed are first processed to impart the middle-high part definition embossing 13.
The liquid-permeable top sheet 3 and the absorbent body 6 are completely fixed by the above, and then the center embossing 8 is applied to effectively expand the top sheet opening or the fiber gap of the nonwoven fabric. You will be able to.

Further, the medium-high absorbent body 6 is provided as in this example,
The side embossments 13b, 13 are provided on the side portions of the middle-high absorbent body 6.
In the case where b is formed, the side embossing 13
b and 13b, the middle-high absorbent body 6 is held in a raised shape, and the center-embossing 8 is added to the middle-high absorbent body 6 so that the cross-sectional shape of the middle-high absorbent body 6 extends over the center embossing 8 on both sides. Both have a mountain shape that swells to the upper surface side, so that body fluid easily flows into the concave groove of the center emboss 8. The side embossments 13b, 13
The formation position of b (indicated by ▼ in FIG. 2) is preferably formed in the outer range of 0 to 10 mm (S) from the side edge position of the middle-high absorbent body 6. Distance S from the side edge of the medium-high absorbent is 10 mm
When the center embossing 8 is applied, it is not possible to effectively enlarge the opening of the top sheet or the fiber gap of the non-woven fabric when the center embossing 8 is applied, and the middle-high absorbent bodies 6 on both sides across the center embossing 8 are expanded to the upper surface side. It will not be possible to form the protruding mountain shape. In this case, the side embossment 13b,
Most preferably, 13b is formed at a position (S = 0 mm) at the mid-high absorbent body 6.

When the center embossing 8 is applied, in order to form the middle-high absorbent bodies 6 on both sides straddling the center embossing 8 into a mountain shape which bulges to the upper surface side, a napkin of the center embossing 8 and the side embossing 13b, 13b is formed. It is desirable that the widthwise spacing SB of 10 to be 25 mm.

[Second Embodiment] Next, the sanitary napkin 1B according to the second embodiment shown in FIGS. 6 and 7 will be described in detail.

The sanitary napkin 1A according to the first embodiment.
Explaining only the differences in comparison with the present, the sanitary napkin 1
In B, the structure does not have the medium-high absorbent body 6, and the branch embosses 8a and 8b branching into V-shapes are formed at the front end portion and the rear end portion of the center emboss 8, and the side embosses 13b and 13b are formed. Has a shape that does not close on the rear end side of the napkin.

When the center embossing 8 is simply formed like the first embodiment, wrinkles are formed on the liquid permeable top sheet 3 at the front end and the rear end of the center embossing 8. Since it was found that the opening of the topsheet or the fiber gap of the non-woven fabric could not be expanded in this portion, wrinkles were eliminated by forming the branch embosses 8a and 8b, and the opening of the topsheet was also formed in the front and rear end portions. Or the fiber gap of the nonwoven fabric can be increased.

The side embossments 13b, 13b do not need to be closed as shown in the figure, and may be formed on both sides of the center emboss 8 along the longitudinal direction.

The structure other than the above is the same as that of the first embodiment, and therefore, the same reference numerals are given and the description thereof will be omitted.

[0045]

As described above in detail, according to the present invention, by defining the conditions for forming the groove-shaped embossing, the shape characteristics, etc., even if a large amount of body fluid is instantaneously discharged, this body fluid will leak. It will be able to be held and absorbed by the center embossed part so that it does not exist.
