Description

Absorbent article

The present invention relates to an absorbent article.

An example of the absorbent article is a sanitary napkin. Patent Document 1 discloses a sanitary napkin 1 having an absorbent body 4 on which a dot-shaped embossment 7 is formed. And the absorption performance is improved by the capillary phenomenon caused by the fiber density difference formed by the dot-shaped embossment 7.

Patent Document 1: JP-A-2008-136564

However, in the sanitary napkin 1 of Patent Document 1, the dot-shaped embossment 7 is provided in a regular pattern. The body fluid absorbed in the region (H) indicating the body fluid discharge region is shifted to the capillary action so that the body fluid diffuses in a substantially concentric circular shape. At this time, in the absorbent article such as the sanitary napkin 1, the length in the longitudinal direction of the absorbent article 4 can be adjusted depending on the use, but since the length in the width direction is limited by the crotch length of the user, The length is shortened. Therefore, although the range of absorption in the longitudinal direction is widely formed, the body fluid diffused in a substantially concentric circular shape may leak from the end in the width direction of the absorbent article 4. [

The absorber includes a central guide portion and a front press portion configured to guide the excrement. The central guide portion is provided in a central region of the absorbent body in the width direction which is pierced in the thickness direction and along the longitudinal direction. And the front squeeze portion is provided in a front region of the absorbent body in the longitudinal direction so as to be folded in the thickness direction and to follow the longitudinal direction. A value obtained by dividing a half of the length in the longitudinal direction of the excrement existing region by the length in the width direction of the excrement existing region when the absorber existing region is defined as the region in which the excrement exists, Wherein a distance from the most front side end in the longitudinal direction of the front side pressing portion of the absorbent body to a center in the longitudinal direction of the winged adhesive portion is equal to or larger than a value obtained by dividing the distance in the width direction of the absorbent body at the center, The inducing part induces the excrement.

The napkin 1 also includes a napkin body portion 20 provided with the absorbent body 10 and a pair of wing portions 30 extending outward in the width direction from the longitudinal center region of the napkin body portion 20 .

The topsheet 3 is a liquid-permeable sheet, and an air-through nonwoven fabric or the like can be exemplified. The backsheet 5 is a liquid-permeable sheet, and can be exemplified by a resin film of polyethylene (PE) or the like. The planar shape of the topsheet 3 and the backsheet 5 are the same and the planar size thereof is larger than the absorber 10 and covers the entire plane of the absorber 10.

On the non-skin side of the napkin body 20 (the non-skin side of the back sheet 5), a sticky portion 21 for the body is provided. When the napkin 1 is used, the adhesive portion 21 for the main body is adhered to the skin side of the undergarment or the like, whereby the napkin 1 is fixed to the undergarment or the like. The adhesive portion 21 for the main body shown in Fig. 2 has a rectangular shape with long sides in the longitudinal direction. Three adhesive portions are arranged at intervals in the longitudinal direction, and the rows of the three adhesive portions are arranged in eight columns at intervals in the width direction.

Likewise, the non-skin side of each wing 30 (the non-skin side of the back sheet 5) is provided with an adhesive portion 31 for the wing. When the napkin 1 is used, the wing portion 30 is folded toward the non-skin side, and the adhesive portion 31 for the wing portion is adhered to the side surface of the non-skin of the undergarment or the like, whereby the napkin 1 is fixed to the undergarment or the like. The adhesive portion 31 for a wing portion shown in Fig. 2 is a rectangular adhesive portion having long sides in the longitudinal direction.

The absorber 10 is a member that absorbs excreta and keeps it inside. The absorbent core 10 has a skin side sheet 11 on the skin side of the absorbent core 12 and a non-skin side sheet 13 on the skin side of the absorbent core 12. The members 11 to 13 are laminated in the thickness direction. The absorbent core 12 is made of pulp fibers or the like which are liquid absorbent fibers that are formed into a longitudinally long shape at the time of planarization (broken line portion in Fig. 1). As the liquid absorbent fiber, a super absorbent polymer (so-called SAP), which is a liquid absorbent granular material, is added to the pulp fiber. The absorbent core 12 is composed of about 90% of the unit weight of the liquid absorbent fiber and about 10% of the unit weight of the SAP. As the liquid-absorbent fiber, a cellulose-based absorbent fiber can be mentioned.

The skin-side sheet 11 is a liquid-permeable sheet, and tissue paper or the like can be exemplified. The non-skin side sheet 13 may be a liquid-permeable sheet or a liquid-permeable sheet, and may be exemplified by SMS (spunbond / meltblown / spunbond) nonwoven fabric. The absorbent core 12, the skin-side sheet 11 and the non-skin-side sheet 13 are planar in substantially the same shape, and the absorbent core 12 is covered with an adhesive (not shown) (Fig. 3). The skin-side sheet 11 and the non-skin-side sheet 13 may have different planar shapes, and the respective members 11 to 13 may not be bonded to each other with an adhesive.

The napkin 1 includes a front region R1, a center region R2 and a rear region R3 in order from the front side in the longitudinal direction (Fig. 1). Refers to a region on the front side of a portion where the napkin 1 has the greatest width in the upper side than the portion 31 for the wing portion in the region on the front side of the portion provided with the wing portion 30 . The term "rear region R3" refers to a region behind the portion where the napkin 1 has the greatest width in the backward side of the wing portion-attaching portion 31 in the region behind the portion provided with the wing portion 30 . The region provided with the wing portion 30 in the region between the front region R1 and the rear region B in the longitudinal direction is referred to as a central region R2. The napkin 1 is individually folded into three folds by the front folding section Ff located in the front region R1 and the rear folding section Fb located in the rear region R3.

&Lt; Regarding the central guide portion 14, the absorptive point press portion 15 and the press portion 25,

4 is a plan view of the absorber 10 seen from the non-skin side. 5 is an enlarged schematic view of the absorptive point press-bonding portion 15 seen from the skin side of the absorber 10. The end portions of the absorbers 10 in the longitudinally elongated shape in the plan view at the both lateral ends in the width direction are referred to as a transverse section 10e and the ends of the curved shape at the front in the longitudinal direction are referred to as the front end section 10et, The end portion of the curved shape of the rear end portion 10eb is referred to as a rear end portion 10eb. The absorber 10 is a so-called thin absorber having a thickness of 3 mm or less, preferably 2 mm or less, by the absorptive point crimping portion 15.

As shown in Figs. 4 and 5, the absorber 10 has a longitudinal direction extending from a front end portion 10et to a rear end portion 10eb, a width direction extending from a transverse portion 10e on one side, (15e) arranged in a zigzag manner in a region between the absorbent core (10e). The absorber pointed pressed portion 15 is separated from the skin side and the non-skin side respectively in the thickness direction. Each planar shape of the absorber point compression portion 15 is an elliptic shape having a length Lm1 in the longitudinal direction longer than a length Lm2 in the width direction (Lm1 > Lm2). This promotes diffusion of feces in the longitudinal direction.

In the absorber pointed press portion 15, the intervals between the centers of the adjacent absorber pointed portions 15 in the width direction are equal and the centers of the absorptive pointed portions 15 adjacent in the longitudinal direction are equally spaced from each other. Thus, the diffusion of excretion can be made constant while the rigidity of the absorber 10 is kept constant. The interval Lb between the edge portions of the adjacent absorber pointed portions 15 in the width direction is shorter than the width Lm2 in the width direction of the absorber pointed portion 15 (Lm2 > Lb). The intervals Lj of the edges of the absorber pointed press portions 15 adjacent in the longitudinal direction are shorter than the interval Lb of the edge portions of the absorber pointed portions 15 adjacent to each other in the width direction (Lj <Lb).

The absorbent body (10) is provided with a central guide portion (14) along the longitudinal direction at a central portion in the width direction. The central guide portion 14 is separated from the skin side and the non-skin side in the thickness direction from the front end portion 10et to the rear end portion 10eb of the absorber 10, respectively. The central guide portion 14 guides the absorber 10 to the skin side in the thickness direction with the central guide portion 14 as a starting point. Further, the central guide portion 14 guides the excrement or the like in the longitudinal direction. The induction of the bending by the central guide portion 14 and the induction of the excrement will be described later in detail.

The pointed crimping portion 25 is a circular crimped portion in which the topsheet 2 and the absorbent body 10 are pressed together in the thickness direction. The pointed crimping portion 25 is sliced in the thickness direction from the skin surface side and discretely provided in a substantially closed region where the crimping portions 26, 27, 28 described below are partitioned on the topsheet 2.

6A to 6D are diagrams for explaining the formation of the central guide portion 14, the absorber point-to-point crimp portion 15 and the point-to-point crimp portion 25. Fig. Fig. 6A is a schematic cross-sectional view of the absorber 10 in the portion indicated by the arrow E-E in Fig. 1, in which the absorber dot presser 15 is formed. 6B is a schematic sectional view of the absorber 10 of FIG. 6A in which the central guide portion 14 is formed. 6C is a schematic cross-sectional view of the topsheet 3 laminated on the absorber 10 of Fig. 6B. 6D is a schematic sectional view of the portion of the napkin 1 indicated by the arrow E-E in Fig. 6 (a), 6 (b) and 6 (c) are the center line of the absorber 10 in the thickness direction. 6D, Y-Y is the center line of the napkin 1 in the thickness direction. The central guiding portion 14, the absorber pointed press portion 15 and the pointed press portion 25 are arranged in the gap between rolls between a convex roller (not shown) and an anvil roller (not shown) 3) are passed through the superposed absorber 10 and subjected to compression bonding. The convex roller includes a plurality of projections, and the anvil roller has a flat surface.

First, an absorbent body pointed press portion 15 is formed. (Embossing) from the non-skin surface side of the absorbent body 10 before processing, the absorbent body point pressed portion 15 is formed, and the uncompressed region a is formed by compression bonding, b are formed (Fig. 6A). In the region b, the liquid absorbent fiber is crushed, the thickness becomes thinner than the region a, and the density of the liquid absorbent fiber becomes higher than that of the region a. That is, the density of the liquid-absorbent fiber is higher than the end portion of the absorber dot-shaped squeeze portion 15 at the center portion bc of the absorber dot-shaped squeeze portion 15 in the width direction. At this time, the absorber point compression portion 15 is located substantially at the center of the absorber 10 in the thickness direction.

Subsequently, the central guide portion 14 is formed. The central guide portion 14 performs the depression / compression process from the non-skin surface side to the central portion in the width direction of the absorbent body of the absorber 10 in which the absorber pointed press portion 15 is formed. The central guide portion 14 is formed, and a depressed region c is newly formed from the skin side and the non-skin side (Fig. 6B). As in the case of the absorptive point crimping portion 15, the region c is formed by crushing the liquid absorbent fiber to have a thickness smaller than that of the region a, and the density of the liquid absorbent fiber is higher than that of the region a. That is, the density of the liquid-absorbent fiber is higher in the widthwise direction than in the center portion cc of the central guide portion 14.

It is preferable that the density of the liquid absorbent fiber is higher than the center portion cc of the central guide portion 14 by the center portion bc of the absorbent core pointed portion 15. This can be realized by pressing the absorber spot-shaped crimping portion 15 with a pressure larger than that by which the central guiding portion 14 is formed. As a result, the excrement absorbed by the central guide portion 14 can be first guided to the absorber-point press-bonding portion 15 having a higher density of the liquid-absorbent fiber. However, when the central guide portion 14 is further formed at the portion where the absorber point compression portion 15 is formed, the thickness of the central guide portion 14 is partially thinned, and the density of the liquid absorbent fiber is further increased.

Subsequently, as shown in Fig. 6C, the topsheet 3 is laminated from the skin side of the absorbent body 10 and is fixed with an adhesive (HMA). 6C and 6D, the adhesive is omitted.

Then, the pointed crimping portion 25 is formed. The topsheet 3 and the absorbent body 10 are pressed together from the skin surface side together in the thickness direction to form a dent region d from the skin side (Fig. 6D). Thereafter, the back sheet 5 is laminated on the non-skin side and fixed with an adhesive to form the napkin 1. [ In the region d, the liquid-absorbent fiber is further crushed to become thinner than the region a, and the density of the liquid-absorbent fibers becomes higher than that of the region a. That is, the density of the liquid-absorbent fiber is higher than the end portion of the pointed crimping portion 25 at the center portion dc of the pointed crimping portion 25 in the width direction. At this time, the pointed crimping portion 25 is located substantially at the center of the napkin 1 in the thickness direction. In Fig. 6D, the pointed crimping portion 25 is formed at the portion where the absorber pointed crimping portion 15 is formed, but the present invention is not limited to this. The absorber point compression unit 15 and the point compression unit 25 may be formed at the same position or at different positions.

<Regarding the Compression Parts 26, 27, 28, and 29>

In addition, the napkin 1 is provided with linear pressing portions 26, 27, 28, 29 which are paired toward the non-skin side from the skin side in the thickness direction. The density of the liquid absorbent fibers of the linear crimping portions 26, 27, 28, 29 is higher than that of adjacent portions. The topsheet 3 and the absorbent body are pressed (embossed) from the side of the skin in the thickness direction by the pressing portions 26, 27, 28, 29, and are joined and integrated. The crimping portions (26, 27, 28) have a generally annular shape elongated in the longitudinal direction as a whole.

[ The overlapping pressed portion 27c is provided in the rear region R3 on the rear side of the linear crimping portion 27a. The overlapping pressed portion 27c is located at the front end of the linear crimping portion 28b (described later) from the outside in the width direction and at both ends in the width direction of the absorbent body 10. [ Each end of the rear side of the overlapping crimping portion 27b and each end of the front side of the linear crimping portion 27a are connected to each other. Each end of the rear side of the linear crimping portion 27a and each end of the front side of the overlapping crimping portion 27c are connected to each other.

The crimping portion (second crimping portion) 28 is provided in the rear region R3 and includes a rear crimping portion 28a and a linear crimping portion 28b. The crimping portion 28 is in a shape symmetrical with respect to the central guide portion 14. The rear side pressing portion 28a is located at the rear most side, and intersects the longitudinal direction, and follows the contour of the napkin 1 roughly. Each end of the front side of the rear side crimping portion 28a and each end of the rear side of the linear crimping portion 28b are connected to each other. The linear crimping portion 28b is provided from the front side of the rear pressing portion 28a to the front side portion of the rear side region R3 from each end of the front side of the rear pressing portion 28a.

The crimping portion 29 (first crimping portion) is located in the rear region R3 and is provided inward in the longitudinal direction and the width direction of the crimping portion 28. [ The crimping portion 29 includes an inner crimping portion 29a and a linear crimping portion (rear linear crimping portion) 29b. The pressing portion 29 has a shape symmetrical with respect to the central guide portion 14. [ The inner squeeze portion 29a intersects the longitudinal direction in a convex shape from the front side to the rear side of the rear squeezing portion 28a and has a shorter length in the width direction than the rear squeezing portion 28a. Each end of the lower side of the linear crimping portion 29b and each end of the front side of the inner crimp portion 29a are connected to each other. The linear crimping portion 29b is provided from the rear side of the linear crimping portion 29b to the front side portion of the rear region R3 from each end of the front side than the inner crimp portion 29a.

In the present embodiment, the boundary between the front side crimping portion 26a and each linear crimping portion 26b, the boundary between the linear crimping portion 27a and each of the overlapping crimping portions 27b, 27c, the rear crimping portion 28a, And the linear compression portion 28b, the inner compression portion 29a and the linear compression portion 29b are set for convenience, but the invention is not limited thereto.

[ The overlapping press portions 27b and 27c do not necessarily have to be provided. However, by providing the overlapping press portions 27b and 27c, the excretion leaks from the portion where the bending operation by the folding portions Ff and Fb is likely to occur It is possible to further reduce the risk of discarding. The length and shape of the respective crimping portions 26, 27, 28, 29 can be arbitrarily set.

&Lt; Induction for bending the absorber 10 to the skin side by the central guide portion 14 >

The central guiding portion 14 provided in the absorbent body 10 can be guided to bend toward the skin in the thickness direction with the central guiding portion 14 in the thickness direction as a starting point. Accordingly, when the napkin 1 is worn, when the pushing force of the wearer's leg is applied, the central area in the longitudinal direction of the absorbent article 10 is deformed into a shape convex toward the skin toward the center from the side in the width direction. Fig. 7 is a view for explaining the use of the napkin 1. Fig. When the user attaches the napkin 1, the napkin 1 is pulled up to the user's groin 201K side while the napkin 1 is fixed to the crotch part of the undergarment (crotch part). At this time, as shown in state A of Fig. 7, the napkin 1 provided with the absorbent body 10 is bent toward the skin along the central guide portion 14. As shown in Fig. When the napkin 1 is mounted on the user's groin 201K, as shown in the state B of Fig. 7, the portion bent toward the skin along the central guide portion 14 is formed by the excretion hole 201He It becomes easy to touch the existing gap. As a result, it is easy for the user to feel good fitability, and excrement such as menstrual discharge can be easily absorbed by the absorber 10 without being leaked.

&Lt; Induction of the excretion by the central guide portion 14 >

The central guide portion 14 has a shape along the longitudinal direction and is crushed in the thickness direction by the pressing process to increase the density of the liquid absorbent fiber. This can lead the liquid such as excretion in the longitudinal direction. Hereinafter, the diffusion of liquid such as excretion will be described. In this embodiment, diffusion of excretion and the like in the absorber 10 is caused by the ratio of the liquid absorbent fibers in the absorber 10 (liquid absorbent fiber: SAP = 90: 10) And the like are being promoted. The term "capillary phenomenon" is also referred to as "capillary phenomenon", and the degree of rise or effect of the liquid level in the tube is proportional to the surface tension of the liquid and inversely proportional to the inner diameter of the tube. In the present embodiment, a space between fibers corresponds to a tube, and a narrow space between fibers and fibers refers to a phenomenon in which a liquid penetrates without gravity or up / down / left / right. The narrower the gap of the liquid absorbent fiber is, the faster the penetration of the liquid becomes. That is, the higher the density of the liquid-absorbent fiber, the more the excretion is diffused.

8A to 8D are views showing an absorbent body having a topsheet, an absorbent core, and a back sheet as in the case of the absorbent body 10 of the present embodiment, after a predetermined time has elapsed after a predetermined amount of liquid has been dropped. 8A to 8D, the vertical direction in each drawing is the longitudinal direction, and the lateral direction is the width direction.

First, Fig. 8A is a view for explaining an absorber having no absorber point crimping portion and a central guide portion. In this case, since the absorber does not have the pointed crimping portion and the central guide portion, the dropped liquid almost immediately concentrically and almost stays at the dropping place.

Fig. 8B is a view for explaining an absorber having an absorptive point compression portion and not having a central guide portion. Fig. In this case, the dripped liquid is promoted between the adjacent absorber point press-contact portions by the capillary phenomenon of the absorber point press-bonded portion having a higher density of the liquid absorbent fibers. The dropped liquid diffuses over a wider range than in the case of FIG. 8A. At this time, the liquid diffuses to the same extent in the longitudinal direction and the width direction, and diffuses in a substantially concentric circular shape.

Fig. 8C is a view for explaining an absorber having no central absorber point crimping portion and having a central guide portion. Fig. As a result, the dripped liquid promotes the diffusion of the liquid along the central guide portion due to the capillary phenomenon of the central guide portion having a higher density of the liquid-absorbent fibers. The diffusion of the liquid does not proceed much in the width direction, but the liquid is diffused more prolonged with respect to the portion along the central guide portion.

Fig. 8D is a view for explaining an absorber having an absorber point compression portion and a central guide portion. Fig. The diffusion of the liquid along the central guide portion is promoted by the capillary phenomenon of the central guide portion promoted between the adjacent absorber point press portions by the capillary phenomenon of the absorptive point press portion having the higher density of the liquid absorbent fibers, do. As a result, the diffusion of the liquid is promoted also in the width direction and the length direction. At this time, in the case where only the absorptive point press-bonding portion is formed (Fig. 8B), the liquid is diffused by the central guide portion, while the liquid is diffused almost concentrically. The diffusion effect of the liquid by the absorptive point press-bonding portion and the diffusion effect of the liquid by the central guiding portion are combined, so that the region where the liquid is diffused becomes a vertically long oval shape (Fig. The absorber point press-formed portions formed at uniform intervals in the absorber are diffused in the width direction and the longitudinal direction, and the range in which the excretion is spread is made to be substantially concentric. However, the central guide portion is formed along the longitudinal direction of the absorber, and further spreads the liquid in the longitudinal direction.

The central guide portion can change the amount of diffusion of the liquid by changing the depth of depression (compression) of the central guide portion, the length in the longitudinal direction, the area where the central guide portion is formed, and the like. For example, the central guide portion formed by the squeezing of a higher pressure can increase the density of the liquid absorbent fiber, and further promote the spread of the liquid in the longitudinal direction. Further, since the central guide portion having a longer and wider area has a wider area where the density of the liquid absorbent fiber is high, the diffusion of the liquid in the longitudinal direction can be further promoted.

For example, a predetermined amount (for example, 5 ml) of liquid such as artificial menstrual blood is dropped to the absorber at approximately the center of the absorber, and the state after a predetermined time (for example, after 60 minutes) is observed. According to the result, the central guide portion can be adjusted. When it is judged that the diffusion in the longitudinal direction is insufficient, the compression of the central guide portion may be made stronger or the length of the central guide portion in the width direction may be made longer. Further, by making the length of the central guide in the longitudinal direction longer, it is also possible to diffuse the liquid further outward in the longitudinal direction of the absorber. Further, with respect to the absorber having the liquid absorbent fiber and the SAP, the liquid diffusing property can be improved by further increasing the ratio of the liquid absorbent fiber. On the other hand, when it is judged that the diffusion in the longitudinal direction has progressed excessively, the compression of the central guide portion may be further weakened or the width of the central guide portion may be formed in a short and narrow range. Further, the composition ratio of the SAP of the absorber may be increased.

Further, by combining not only the central guide portion but also the central guide portion and the pointed and linear pressed portion, the spread of the liquid can be adjusted more flexibly. The pressing range of the central guiding portion, the pointed and linear pressing portion, the strength of the pressing and the like may be determined by observing the condition as in the case of the adjustment of the central guiding portion.

For example, when the diffusion of the liquid in the width direction is excessively advanced and the diffusion of the liquid in the longitudinal direction is insufficient, the central guiding portion is formed by stronger crimping to promote diffusion in the longitudinal direction, The number of liquids diffused in the width direction may be reduced. Likewise, in the case where the liquid is appropriately diffused in the longitudinal direction and the liquid is not sufficiently diffused in the width direction, the diffusion in the width direction can be suppressed by increasing the number of the pressure- Can be further promoted. The diffusion of the liquid in the longitudinal direction and the diffusion of the liquid in the width direction can also be changed by changing the density in the longitudinal direction of the pointed compression portion and the density in the width direction of the compressed compression bonded portion.

<<< Regarding the Efficiency of the Napkin 1 according to the Present Embodiment >>>

Fig. 9 is a schematic diagram for explaining the excreted presence area Q (q) when the napkin 1 absorbs excreta. The fecal material presence area Q refers to a region where feces or the like is present when the absorbent body 10 of the napkin 1 absorbs feces or the like and can recognize the feces or the like when the napkin 1 is viewed from the skin side Range. Fig. 9 schematically shows a state after a certain period of time has elapsed by the user using the napkin 1, and a state of absorbing a predetermined amount of excretion or the like. In addition, the excrement existing region Q does not have a constant shape but may have a distorted shape or a color with a speckle. In the following description, the elliptical shape circumscribed in the excrement existing region Q (the dotted line region in FIG. 9) will be described as the excrement existing region q.

A predetermined amount of liquid is dropped onto the napkin 100 having no central guide portion 14 and the pressed portion 26 and the napkin 1 according to the present embodiment, The results are compared and explained. The absorbent body 101 of the napkin 100 and the absorbent body 10 of the napkin 1 are both about 285 mm in length in the longitudinal direction and about 70 mm in the width direction. The liquid to be dropped on the napkin 100 and the napkin 1 is a colored liquid such as water. The liquid drops onto the portion where the center line X-X of the width direction of the napkin 100 or the napkin 1 crosses the blade attaching center line W-W. Then, the region where the dropped liquid is diffused is examined as the excrement existing region Q, and for convenience, the excrement existing region q, which is a schematic diagram of the excrement existing region Q, will be described.

10A is a schematic view showing the state before use of the napkin 100. Fig. In addition, like the napkin 1, the absorbent body 10 of the napkin 100 has a plurality of absorbent body puncture portions 15.

Fig. 10B is a schematic diagram showing a state after a predetermined time has elapsed after liquid is dropped onto the napkin 100 of Fig. 10A. Fig. 10A shows a state in which 0.5 ml of liquid is dropped onto the napkin 100 and one hour has elapsed. At this time, the excrement existing region q is roughly concentric with a length T in the longitudinal direction and a length S in the width direction of approximately 30 mm, and is thus collected inside the absorber 101.

10C is a schematic diagram showing a state after a predetermined time has elapsed after liquid is dropped onto the napkin 100 of Fig. 10A. Fig. 10 shows a state in which 3.0 ml of liquid is dropped onto the napkin 100 of Fig. 10A and one hour has elapsed. At this time, the excrement existing region q is substantially concentric circular with the length T in the longitudinal direction and the length S in the width direction being approximately 75 mm, wider than the state shown in Fig. 10B. Although the absorbent body 101 is wet in the longitudinal direction, it is evacuated outwardly in the width direction. Therefore, although the front side region and the rear side region of the absorbent body 101 hardly absorb the liquid, the liquid leaks from the end portion in the width direction of the absorbent body 101, and there is a fear that the liquid leaks to the outside of the napkin 1 There is a possibility of occurrence.

On the other hand, the napkin 1 according to the present embodiment has the central guiding portion 14 and the crimping portions 26, 27, 28, and 29. 11A is a schematic view showing the state before use of the napkin 1. In the napkin 1 of the present embodiment, the value ((T / 2) / S) obtained by dividing the half (T / 2) of the length T in the longitudinal direction of the excrement existing region q by the length S in the width direction A value H obtained by dividing the distance H from the end portion 26ae on the front side of the front pressing portion 26a to the wing portion attachment center line WW by the length K in the width direction of the absorbent article 10 at the wing attachment portion center line WW ((T / 2) / S? H / K) that is equal to or greater than the center guide portion 14 (H / K).

Here, as described above, the state of diffusion of the excrement or the like changes depending on the squeezing state and shape of the central guide portion, the pressed state or the distribution state of the pointed squeeze portion, and the like. Therefore, for example, the central guide portion 14 that realizes (T / 2) / S? H / K can be formed by the following procedure. First, the three types of napkins (the crimping portions 26, 27, 28, and 29 are the same and the central guiding portion 14 is not formed) having different distribution densities of the pointed crimping portions 25 are prepared. Next, for each napkin, change the pressure and squeeze the central guide portion 14 (the same length). Thereby, it is possible to obtain three kinds of napkins differing only in the pressed state of the central guide portion 14. Next, a liquid (artificial menstrual blood or the like) is dropped on these napkins as described above to observe the state of diffusion to specify a napkin having (T / 2) / S? H / K.

(T / 2) / S? H / K is specified, the central guide portion 14 formed on the napkin may be employed. If there is no napkin having a ratio of (T / 2) / S? H / K, the central guide portion 14 ) May be changed by changing the width and /

Next, the spread state of the excrement in the napkin (napkin having (T / 2) / S? H / K) obtained as described above will be described in more detail with reference to the drawings. 11B is a schematic diagram showing a state after a predetermined time has elapsed after liquid is dropped onto the napkin 1 of Fig. 11A. 11A shows a state in which 0.5 ml of liquid is dropped onto the napkin 1 and one hour has elapsed. At this time, the excrement existing region q becomes a longitudinal oval shape having a length T of about 60 mm in the longitudinal direction and a length S of about 30 mm in the width direction, and is thus collected inside the absorber 10.

11C is a schematic diagram showing a state after a predetermined time has elapsed after liquid is dropped on the napkin 1 of Fig. 11A. 11A shows a state in which 3.0 ml of liquid is dropped onto the napkin 1 in the state of Fig. 11A and one hour has elapsed. At this time, the excrement existing region q becomes a longitudinal oval shape having a length T of about 120 mm in the longitudinal direction and a length S of about 60 mm in the width direction, and is thus collected inside the absorber 10.

11B and 11C, the napkin 1 of the present embodiment is configured such that excretion absorbed at a portion where the center line XX of the absorbent body 10 and the blade attaching center line WW cross each other is guided to the central guide portion 14 Is diffused in the longitudinal direction from the width direction. The value (T / 2) / S) obtained by dividing the half (T / 2) of the length T in the length direction of the excrement existing region q by the length S in the width direction is smaller than (H / K) obtained by dividing the distance H from the wing attachment portion center line WW to the wing attachment portion center line WW by the length K in the width direction of the absorber 10 at the wing attachment center line WW (T / 2) / S? H / K). In any state, the feces existing region q is poured into the inside of the absorber 10, and while the excreta is diffused over a wider area of the absorber 10, So that it is less likely that the slurry leaks outward in the width direction. That is, the excrement can be guided to reach the front side pressing portion 26a before the excrement existing region q reaches the transverse portion 10e of the absorber 10, and in the case of the absorber 101 of the napkin 100 It is possible to absorb the excrement or the like in a wider range of the absorber 10 than in the case of the absorber 10.

Fig. 11D is a schematic view showing the maximum excrement existing area qm of the napkin 1. Fig. The excrement existing region q when the diffused liquid reaches the end 26ae on the front side of the front squeeze portion 26a is referred to as the maximum excrement existing region qm as shown in Fig. A value ((Tm / 2) / Sm) obtained by dividing a half (Tm / 2) of the length Tm in the length direction of the excrement existing area qm by the length in the width direction Sm is smaller than a value (H / K) obtained by dividing the distance H from the wing attachment portion center line WW to the wing attachment portion center line WW by the length K in the width direction of the absorber 10 at the wing attachment center line WW (Tm / 2) / Sm? H / K). Therefore, even when the excrement is spread up to the state of the maximum excrement existing area qm, it is possible to reduce the risk of the excrement leaking from the transverse section 10e of the absorber 10.

The maximum excrement existing area qm is asymmetric with respect to the wing attachment center line W-W in the longitudinal direction. That is, the maximum excrement is present from the blade attaching portion center line WW to the distance from the end portion (the end portion 26ae on the front side of the front pressing portion 26a) to the blade attaching portion center line WW on the front side of the maximum excrement existing region qm The distance to the rear end of the region qm is long. This is because the linear compression portions 28b and 29b provided in the rear region of the absorber 10 facilitate the spread of the excrement in the longitudinal direction. Since the napkin 1 has a longer rear region R3 than the front region R1, the spread of the excretion to the rear region can be promoted by the respective linear crimping portions 28b, 29b, (qm) can be made larger.

In the central region R2 of the absorber 10, one side linear compression portion 27a and the other side linear compression portion 27a along the longitudinal direction are provided. An end portion of each of the linear crimping portions 27a on the outer side in the width direction is an outer end portion 27ae. A value ((T / 2) / S) obtained by dividing the length T in the longitudinal direction of the excrement existing region q by the length S in the width direction of the excrement existing region q is smaller than the value The distance H from the end portion 26ae to the blade attaching center line WW divided by the distance J between the outer end portion 27ae on one side and the outer end portion 27ae on the other side at the blade attaching portion center line WW (I.e., (T / 2) / S? H / J). Thus, before the excrement existing region q reaches the outer end portion 27ae of each linear crimping portion 27a or reaches the outer end portion 27ae, the excrement is guided to reach the front press portion 26a can do.

Further, the napkin 1 includes a plurality of folds Ff and Fb along the width direction for folding the skin surface side inward. Thus, the absorbent body 10 includes a back side pressing portion 28a which is folded in the thickness direction and crosses the longitudinal direction, in the rear region of the absorbent body 10. [ The front side crimping portion 26a is provided on the front side of the front side folding portion Ff closest to the winging adhesive portion 31 and further on the rear side than the rear side folding portion Fb closest to the winging adhesive portion 31 . The front side pressing portion 26a and the rear side pressing portion 28a guide the excrement in the width direction (as26, as28). The front squeezing portion 26a and the rear squeezing portion 28a relieve the slippage of excretion from the front end portion 10et and the rear end portion 10eb of the absorber 10 to the outside. The front side crimping portion 26a is provided on the front side of the front folding portion Ff and the rear side crimping portion 28a is provided on the rear side of the back side folding portion Fb. This can secure the length of the central guide portion 14 provided between the front side pressing portion 26a and the rear side pressing portion 28a and can absorb the excrement or the like in a wider range of the absorbent body 10. [

It is preferable that the absorber 10 includes a line-shaped linear crimping portion 29b which is recessed in the thickness direction and along the longitudinal direction in the rear region of the absorber 10 in the longitudinal direction. When the excrement existing region Q (q) reaches the linear crushing section 29b, the spread of the excrement can be promoted to the rear side ab29 along the linear crushing section 29b. When the back side of the napkin 1 is longer than the front side, it is possible to absorb the excrement in a wider range of the absorber 10 by spreading the excreta more rearwardly. In the present embodiment, linear linear crimping portions 28b, which are formed on the outer side of the linear crimping portion 29b in the width direction and in the rear side of the absorbent body 10 in the longitudinal direction, I have. With respect to the linear crimping portion 28b, the excrement can be further diffused to the rear side ab28. When the excrement existing region Q (q) reaches the linear compression bonding portion 28b, the diffusion in the longitudinal direction is promoted to cause the excrement to leak outward from the transverse portion 10e of the absorber 10 Can be reduced.

The absorber 10 also includes rear-side press portions 28a, 29a which are formed in the rear region of the absorber 10 in the longitudinal direction and which extend in the thickness direction and cross the longitudinal direction. The respective linear crimping portions 28b and 29b are located between the rear end of the wing adhesive portion 31 in the longitudinal direction and the rear end 28ae of the rear crimping portion 28a located at the rear most side . As a result, the excrement promoted to the rear side (ab28, ab29) by the linear crimping portions 28b, 29b is promoted to the outer side (as28) in the width direction when reaching the rear side pressing portion 28a. This can alleviate the risk of the slurry leaking outward in the longitudinal direction from the rear-side press portion 28a.

The napkin 1 also includes a pair of linear crimping portions 29b and a crimping portion 29 including a rear crimping portion 28a connected to each longitudinal end of the linear crimping portion 29b, And a crimping portion 28 including a linear crimping portion 28b, a linear crimping portion 28b and a rear crimping portion 28a connected to each end in the longitudinal direction. In the longitudinal direction and the width direction, it is preferable that the pressed portion 29 is located on the inner side of the pressed portion 28. Thus, even when the excrement is spread to the rear side pressing portion 28a, the linear compressed portion 29b can guide the excrement to the rear side ab29, 28b can reduce the possibility that the excretion leaks outward in the width direction of the absorbent article 10. [ Further, the waste material can be moved to the outside (as29) in the width direction by the rear-side pressing portion 28a. Even when the excrement is spread from the rear side pressing portion 28a to the rear side, the rear side pressing portion 28a of the pressing portion 28 located outside the pressing portion 29 can be moved to the rear side of the absorber 10, It is possible to alleviate the fear of leaking.

The central guide portion 14 of the napkin 1 is provided from the end portion 10et on the front side of the absorbent body 10 to the rear end portion 10eb. It is preferable that the central guide portion 14 intersects the front side pressing portion 26a and the rear side pressing portion 28a. As a result, while the central guiding portion 14 spreads the excrement in the longitudinal direction af14 and ab14, the central guiding portion 14 and the portion that intersects the front side pressing portion 26a and the rear side pressing portion 28a, respectively, The front side pressing portion 26a and the rear side pressing portion 28a can promote the excrement to the outside (as26, as28) in the width direction. This can alleviate leakage of excretion to the outside in the longitudinal direction of the absorber 10. That is, the rear region R3 of the napkin 1 includes a pair of linear crimping portions 28b and a pair of linear crimping portions 29b capable of promoting the excretion in the longitudinal direction, And includes a rear side pressing portion 28a and a rear side pressing portion 29a which are strong in promoting the pressing. Even when the excrement is promoted to the outside in the longitudinal direction by the respective linear crimping portions 28b and 29b, the rear crimping portion 28a substantially plays the role of preventing diffusion in the longitudinal direction, It is possible to reduce the possibility that the excretion leaks to the outside of the bag 10eb.

6D, the center position in the thickness direction at the center portion cc of the central guide portion 14 is located closer to the skin than the center position in the thickness direction at the center portion bc of the absorbent article pointed- desirable. As a result, the absorber 10 is folded toward the skin from the central guide portion 14 and comes into contact with the excretion such as the vaginal opening of the user. Therefore, the excrement absorbed in the central guide portion 14, And is moved to the pointed crimping section 15. [0050] Thereby, it is possible to alleviate the stagnation of the excretion in the portion contacting with the skin, thereby improving the tactile sensation.

6D, the density of the liquid-absorbent fiber is set to be between the region c of the central guide portion 14 and the region b of the absorbent core press-bonded portion 15 adjacent to the central guide portion 14 in the width direction, It is preferable that a region a lower than the central portion cc of the central guide portion 14 and the central portion bc of the absorber pointed press portion 15 is provided. That is, between the region c and the region b where the density of the liquid-absorbent fibers is further increased by the pressing process, a region a in which the density of the liquid-absorbent fibers is relatively low is not provided. The liquid absorbent fibers are absorbed in the central guiding portion 14 in the low region "a" and can store the discharged excrement, and the excrement that can not be stored in the region "a" is absorbed by the adjacent pressure- .
