Japanese Patent No. 4512268 Japanese Patent No. 5171634

  When the absorptive article of patent documents 1 receives the force from both legs from the side, the force is transmitted also to a front field via a side pressing crevice. However, since the absorbent article of Patent Document 1 is not configured such that the front region is curved by such force, there is a possibility that the wearing feeling on the front side of the body is reduced. Moreover, when a bodily fluid is discharged | emitted rapidly etc., there exists a possibility that a bodily fluid may leak along a side pressing recessed part.

  Moreover, in the form of patent document 2, although the 1st bending area | region and the 2nd bending area | region are formed by providing a slit in an absorber, these slits fit the front side of the body of an absorbent article. It is not a consideration of sex.

  In view of the above points, an object of the present invention is to provide an absorbent article that has improved fit to the front side of the body.

  In order to solve the above problems, a first aspect of the present invention includes a liquid-permeable top sheet, a liquid-impervious back sheet, and an absorbent body provided between the top sheet and the back sheet. An absorbent article comprising a main body having an elongated shape having a predetermined length in the front-rear direction and a predetermined width in a direction orthogonal to the front-rear direction. A pressing part that is recessed from the sheet side to the back sheet side is formed, and the pressing part extends in a line symmetry and a front-rear direction with a front-rear direction center line extending in the front-rear direction of the main body as a symmetry axis. A pair of squeezing parts formed in the front-rear direction and a pair formed in front of the pair of squeezing parts in the front-rear direction so as to be symmetric about the front-rear direction center line and spread outward toward the front. The oblique direction pressure part, and the oblique direction pressure The rear end parts are seen in the width direction, and is disposed inside the front-rear direction compressing portion.

  According to the said 1st form, in a front of an absorbent article, a pair of diagonal direction pressing part formed so that it might spread outside toward the front was formed. And since the rear end of this oblique direction compression part is arranged in the front-rear direction compression part as seen in the width direction, when the absorbent article receives force from both legs (both thighs) from both sides, Using the force, the region in front of the absorbent article can be deformed starting from the rear end of the oblique direction squeezing portion. Thereby, the area | region ahead of an absorbent article can be made to fit the front side of a body favorably, and comfortable wearing feeling can be improved.

  Moreover, since the fitting property of the front area | region of an absorbent article improves as mentioned above, a main body can be stuck more favorably to the front side of a body. Thereby, leakage of body fluid can be prevented.

  In the second embodiment of the present invention, a line that bisects the maximum angle formed by two imaginary lines that pass through the rear end of the oblique compression section and contact the oblique compression section is the front-rear direction center line. An angle of 25 to 80 ° is formed with respect to the orthogonal straight line.

  According to the said 2nd form, since the diagonal direction pressing part is arrange | positioned at the predetermined | prescribed angle, the area | region ahead of an absorbent article can be deform | transformed much more along the roundness of the front side of a body.

  In the third embodiment of the present invention, a width direction pressing portion extending in the width direction is formed in front of the pair of front and rear direction pressing portions, and the oblique direction pressing portion is the pair of front and rear direction pressing portions and the above It is separated from the width direction pressing part.

  According to the said 3rd form, it becomes easier to bend a front area | region toward the front side of a body because the width direction pressing part is formed ahead of a pair of front-back direction pressing part, and the front of a bodily fluid Leakage into the water can also be prevented. Moreover, even when a large amount of body fluid is discharged because the oblique direction compressed portion is separated from the front and rear direction compressed portion and the width direction compressed portion, body fluid leaks through the front and rear direction compressed portion and the width direction compressed portion. This can be prevented more reliably.

  In the 4th form of this invention, the front end of the said diagonal direction pressing part is arrange | positioned inside the said front-back direction pressing part seeing in the width direction.

  According to the fourth aspect, since the front end of the oblique squeezing portion is also arranged inside the front-rear direction squeezing portion, it is possible to reduce the portion where the oblique squeezing portion hits the skin in the front side portion, so that it is uncomfortable. Can be reduced, and a comfortable wearing feeling can be enhanced.

  In the fifth embodiment of the present invention, a pair of second portions formed so as to be symmetric with respect to the front-rear direction center line as a symmetry axis and to extend outward toward the rear side behind the pair of front-rear direction pressing portions. An oblique compression unit is formed, and a front end of the second oblique compression unit is disposed inside the front-rear compression unit as seen in the width direction.

  According to the fifth aspect, in addition to the front region, the rear direction region is provided with the oblique squeezing portion, so that deformation along the roundness of the body is possible also in the rear direction. Thereby, the fitting property to the body of the whole absorbent article can be improved.

  According to one aspect of the present invention, an absorbent article with improved fit to the front side of the body can be provided.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  As shown in FIGS. 1 and 2, the absorbent article 1 includes a liquid-impervious back sheet 2, a liquid-permeable front sheet 3, and an absorbent body 4 provided between both the sheets 2 and 3. And a main body (absorbent article main body) 8 having. In order to maintain the shape of the absorbent body 4, the absorbent body 4 may be wrapped with an encapsulating sheet 5 made of crepe paper or nonwoven fabric.

  As shown in FIG. 1, the main body 8 as a whole has an elongated shape having a predetermined length in the front-rear direction, and has a substantially constant predetermined width in a direction orthogonal to the front-rear direction. . And the absorbent article 1 has a substantially line-symmetric shape with respect to the center line CL extending in the front-rear direction. In addition, the absorbent article 1 has a central region M including a region (a body fluid discharge port corresponding region) 20 corresponding to a body fluid discharge port when worn, a front end region F in front of the center region M, and a center region. And a rear end region R located behind M. The central region M has wings WG extending from both sides thereof. The front end region F can be a region in front of the wing WG starting position, and the rear end region R can be a region behind the wing WG starting position. In addition, the absorbent article 1 by this form can also be made into the form in which the wing WG is not provided.

  Side nonwoven fabrics 7 are provided on both side portions on the surface sheet 3 side along the front-rear direction (longitudinal direction). The side nonwoven fabric 7 partially protrudes to the side of the main body 8 and is laminated on the back sheet 2 which also protrudes to the side. The side nonwoven fabric 7 is bonded by an adhesive such as hot melt or an adhesive means such as heat seal or ultrasonic seal. Thus, wings WG are formed on both side portions of the main body 8.

  As the back sheet 2, a sheet material having at least water shielding properties such as an olefin resin sheet such as polyethylene or polypropylene can be used. A laminated nonwoven fabric obtained by laminating a nonwoven fabric on a polyethylene sheet or the like, or a laminated sheet of a nonwoven fabric that is substantially impervious to liquid by interposing a waterproof film can be used. Further, it is more desirable to use a material having moisture permeability from the viewpoint of preventing stuffiness. As such a water-impervious / breathable sheet material, a sheet obtained by melt-kneading an inorganic filler in an olefin resin such as polyethylene or polypropylene to form a sheet and then stretching it in a uniaxial or biaxial direction can be obtained. A porous sheet can be used.

  The top sheet 3 is a liquid-permeable sheet that quickly permeates body fluids such as menstrual blood, venom, and urine. As the surface sheet 3, a porous or non-porous nonwoven fabric, a porous plastic sheet, or the like is preferably used. Examples of the material fibers constituting the nonwoven fabric include olefins such as polyethylene and polypropylene, synthetic fibers such as polyester and polyamide, regenerated fibers such as rayon and cupra, and blended fibers thereof, and natural fibers such as cotton alone or Two or more types can be used in combination. Examples of the nonwoven fabric processing method include a spunlace method, a spunbond method, a thermal bond method, a melt blown method, and a needle punch method. Among these processing methods, the spunlace method is preferable in terms of flexibility and the spunbond method is preferable in that it can produce a nonwoven fabric rich in drapeability, and the thermal bond method is preferable in terms of the ability to manufacture a bulky and soft nonwoven fabric. 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 be used.

  The absorbent body 4 interposed between the back sheet 2 and the top sheet 3 is not limited as long as it is a material that can absorb and retain body fluid, but preferably contains cotton-like pulp and a water-absorbing polymer. As the water-absorbing polymer, a superabsorbent polymer (SAP), a superabsorbent fiber (SAF), and a combination thereof can be used. Examples of pulp include cellulose fibers such as chemical pulp obtained from wood and dissolved pulp, and artificial cellulose fibers such as rayon and acetate. As raw materials for chemical pulp, hardwood, softwood, etc. are used, but softwood is preferably used because of its long fiber length.

  Further, the absorbent body 4 may be mixed with synthetic fibers. As synthetic fibers, polyolefins such as polyethylene and polypropylene, polyesters such as polyethylene terephthalate and polybutylene terephthalate, polyamides such as nylon, and copolymers thereof can be used. It can also be used. In addition, composite fibers such as a core-sheath fiber, a side-by-side fiber, and 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 addition, it is also possible to use a hydrophobic fiber that has been surface treated with a hydrophilizing agent to impart affinity to body fluids.

  The thickness of the absorber 4 can be in the range of 0.5 to 25 mm, and is preferably in the range of 1.5 to 6.5 mm. The absorbent body 4 does not have to have a uniform thickness over the front surface, and may have a structure in which the body fluid discharge port corresponding region 20 is bulged. In addition, the absorbent body 4 is preferably manufactured by a stacking fiber or an airlaid method.

  As the side nonwoven fabric 7, a water-repellent treated nonwoven fabric or a hydrophilic treated nonwoven fabric can be used. For example, in order to increase the effect of preventing permeation of menstrual blood or vaginal discharge or the feeling of touch, it is preferable to use a water repellent nonwoven fabric coated with a silicon-based, paraffin-based, alkylchromic chloride-based water repellent or the like . Moreover, when improving the absorptivity such as menstrual blood in the wing WG, it is preferable to use a nonwoven fabric subjected to hydrophilic treatment as the material of the nonwoven fabric. As a kind of the nonwoven fabric, a soft air-through nonwoven fabric which is difficult to crease and hardly wrinkles is preferable.

  The outer edge of the wing WG may be provided with a squeezed portion having a dot shape or a predetermined shape at a predetermined location for the purpose of joining the side nonwoven fabric 7 and the back sheet 2 and increasing the rigidity.

  The full length of the absorbent article 1 can be 13-45 cm, 14-36 cm, and 17-27 cm. When the full length of the absorbent article 1 is 17-27 cm, the structure of the whole absorbent article 1 or the structure of the main body 8 can be made symmetrical.

  The absorbent article 1 of this embodiment is provided with a plurality of pressing parts (also referred to as compression parts or embosses). This pressing part is formed as a recess recessed from the top sheet 3 to the back sheet 2 side. A pressing part can be formed by passing the laminated body which laminated | stacked the surface sheet 3 on the absorber 4 between a pair of pressurization rolls. For example, the laminated body of the absorber 4 and the surface sheet 3 can be passed through so that a convex roll and a flat roll are respectively arranged on the surface sheet 3 side and the absorber 4 side.

  In the absorbent article 1, the squeezed portion is formed in line symmetry with a center line (longitudinal direction center line) CL extending in the longitudinal direction as a symmetry axis. As shown in FIG. 1, as a pressing part, a pair of front-rear direction pressing parts 11 formed so as to extend in the front-rear direction in a line-symmetric manner with a front-rear direction center line CL extending in the front-rear direction of the main body 8 as a symmetry axis. 11 are formed. In the illustrated form, the first pressing parts 11, 11 extend in the front-rear direction substantially over the central region M, but in a range in the front-rear direction narrower than the range of the central region M, or beyond the central region M in the front-rear direction. It may be provided within a range.

  The absorbent article 1 receives forces from both legs when worn. The force from both the legs is also transmitted to the front and rear of the front-rear direction pressing parts 11, 11. Thereby, for example, since the side portion of the front region F is pulled rearward, tensile stress is generated in the entire front region F, and it may not be possible to fit the front side of the body well.

  On the other hand, in this embodiment, in the front region F of the absorbent article 1, a pair of oblique compression parts 12, 12 are arranged symmetrically about the front-rear direction center line CL as an axis of symmetry. The pair of oblique compression parts 12 and 12 are formed so as to spread outward toward the front, and the rear ends 12a and 12a of the oblique compression parts 12 and 12 are respectively seen in the width direction. It is arrange | positioned inside the front-back direction pressing parts 11 and 11. FIG. Stress tends to concentrate on such a pair of obliquely squeezed portions 12 and 12, particularly rear ends 12a and 12a. Therefore, the absorbent article 1 can be deformed starting from the rear ends 12a, 12a of the oblique compression parts 12, 12.

  FIG. 3 is a diagram schematically showing the deformation of the absorbent article 1. Fig.3 (a) (FIG. 3 center) is the top view of the same absorbent article as the absorbent article 1 shown in FIG. Fig. 3 (b) (left side in Fig. 3) is a view schematically showing a II-II cross section of the absorbent article 1 at the time of wearing, and Fig. 3 (c) (lower side in Fig. 3) is a drawing at the time of wearing. It is the figure which showed the III-III cross section of the absorbent article 1 typically. In FIG.3 (b) and FIG.3 (c), the absorbent article before mounting | wearing (before a deformation | transformation) is shown with the code | symbol 1 '.

  As described above, when the absorbent article 1 is worn, the absorbent article 1 receives a force from both legs (indicated by white arrows in the figure) and is pressed from both sides, and the absorbent article 1 is legged by the pressing force of both legs. Deforms to follow the roundness. At that time, the pressing force of the legs is transmitted in the front-rear direction via the front-rear direction compressed parts 11, 11, and the side part of the front region F is pulled obliquely rearward. By such a force, the front part of the absorbent article 1 is a cross section (III-III line cross section, FIG. 3 (c)) cut along the front-rear direction center line CL, starting from the oblique compression parts 12 and 12. Stand up to the body side (upper side). At the same time, as viewed in the cross section cut in the width direction (II-II line cross section, FIG. 3B), the area near the center line CL in the front-rear direction is curved so as to protrude forward. Thereby, the front area | region F of the absorbent article 1 can deform | transform three-dimensionally along the roundness of the pubic part of the front side of a body.

  Since the diagonal direction pressing part 12 by this form is formed by pressing together the surface sheet 3 and the absorber 4, there also exists a problem that the surface sheet 3 floats from the absorber 4 and the absorber 4 is twisted. Hard to occur. Therefore, a comfortable wearing feeling can be obtained even when used for a long time.

  Moreover, since the front area | region F of the absorbent article 1 can deform | transform along the roundness of the front part of a body in this way, the adhesiveness to the front side part of the body of the absorbent article 1 improves. Therefore, leakage of body fluid can be suppressed well.

  In addition, the rear end 12a of the diagonal direction pressing part 12 is arrange | positioned inside the front-back direction pressing part 11 seeing in the width direction, and from the rear end 12a of the diagonal direction pressing part 12 to the front-back direction centerline CL When the distance d in the width direction is compared with the maximum distance D in the width direction from the front-rear direction compressed portion 11 to the center line CL in the front-rear direction, the latter is included (FIG. 1). In the form of FIG. 1, the pair of front-rear direction pressing parts 11, 11 extends linearly in the front-rear direction with an equal interval, so that it is half the distance between the pair of front-rear direction pressing parts 11, 11. Is equal to the distance D.

  A pair of front and rear direction pressing parts 11 and 11 may have a curved shape as shown in FIGS. 4A and 4B. In the form shown to FIG. 4A, a pair of front-back direction pressing parts 11 and 11 have the shape swelled to the width direction outer side. In this case, the distance D is half of the distance between the front-rear direction compressed parts 11 and 11 in the center as viewed in the front-rear direction of the front-rear direction compressed part 11. Moreover, with the form shown to FIG. 4B, a pair of front-back direction pressing parts 11 and 11 have the shape constricted to the width direction inner side. In this case, the distance D is a half of the distance between the front-rear direction compressed parts 11, 11 at the front end or rear end of the front-rear direction compressed part 11. 4A and 4B, the distance d in the width direction from the rear end 12a of the oblique compression unit 12 to the center line CL in the front-rear direction is smaller than the distance D. 4A and 4B are diagrams for illustrating the positional relationship between the front-rear direction pressing portion 11 and the oblique direction pressing portion 12, and some reference numerals are omitted in these drawings.

  In addition, the rear end 12a of the oblique compression unit 12 is disposed inside the front / rear compression unit 11 when viewed in the width direction, and the position of the rear end 12a of the oblique compression unit 12 and the front / rear direction When comparing the position of the front end of the direction pressing part 11 in the width direction, the latter may include being closer to the front-rear direction center line CL. In addition, the width direction pressing part 15 extended in the width direction is provided ahead of a pair of front-rear direction pressing parts 11 and 11, and a pair of front-rear direction pressing parts 11 and 11 and the width direction pressing part 15 are connected. In the case (described later), the front end of the front-rear direction compressed portion 11 can be a curvature change point at the connecting portion. In that case, the position of the rear end 12 a of the oblique direction pressing part 12 is on the inner side than the position of the end part of the width direction pressing part 15.

  In FIG. 5, the enlarged view of the diagonal direction pressing part 12 is shown. As is clear from FIG. 5, the oblique direction compressed portion 12 has a shape that spreads outward from the rear end 12 a toward the front. In this case, two imaginary lines X1 and X2 passing through the rear end 12a of the oblique direction squeezing part 12 and in contact with the oblique direction squeezing part 12 are such that the angle β formed by these imaginary lines X1 and X2 is maximized. The angle α formed by the inclined center line Y that bisects the angle β and the straight line perpendicular to the front-rear direction center line CL is preferably 25 to 80 °, and more preferably 45 to 75 °. preferable. By making angle (alpha) into the said range, the effect which deform | transforms the front area | region F of the absorbent article 1 along the roundness of the front side of a body can be exhibited more favorably.

  The oblique direction compressed portion 12 is preferably disposed such that the rear end 12a is separated from the front-rear direction center line CL by 1.0 to 2.5 cm in the width direction, and is arranged to be separated by 1.5 to 2.0 cm. It is more preferable. Moreover, the rear end 12a of the oblique direction pressing part 12 is 5.0-7 from the line orthogonal to the front-rear direction center line CL in the center of the full length of the absorbent article 1 or the center of the center region when viewed in the front-rear direction. The distance is preferably 0.0 cm, and more preferably 5.0 to 6.0 cm.

  In the form of FIG. 5, since the oblique direction pressing part 12 is groove shape, the said inclination centerline Y is a centerline which passes along the center of the width | variety of a groove | channel. When the oblique direction pressing part 12 is groove-shaped, the length of the oblique direction pressing part 12 is preferably about 5 to 20 mm.

  The oblique direction pressing portion 12 may have a shape other than the groove shape, and may have a shape having a predetermined area, for example, a heart shape as shown in FIG. When the oblique direction compressed portion 12 has a shape having a predetermined area, the rigidity of the portion is increased, so that the function as a starting point of bending is further ensured.

  Also in the form of FIG. 6, as described in the form of FIG. 4, virtual lines X <b> 1 and X <b> 2 passing through the rear end 12 a of the oblique direction pressing part 12 and in contact with the oblique direction pressing part 12 are represented by these virtual lines X <b> 1 and X <b> 2. When the formed angle β is maximized, the angle α formed by the inclined center line Y that bisects the angle β and the straight line perpendicular to the front-rear direction center line CL is preferably 25 to 80 °. More preferably, it is 45 to 75 °.

  Moreover, as shown in FIG. 7, the oblique direction pressing part 12 may include a plurality of independent pressing parts. In the form shown in the figure, two heart-shaped oblique compression parts 12 ′ and 12 ″ are arranged side by side on the inclined center line Y. In this case, the shape and size of a plurality of independent oblique pressing parts can be the same or different.

  The shape of the oblique direction pressing part 12 is not particularly limited, and may be a shape other than the groove shape (FIG. 5) and the heart shape (FIGS. 6 and 7). For example, it may be a drop shape, an arrow shape, an inverted triangle, an inverted pentagon, etc. as shown in FIGS. As shown to Fig.8 (a)-(d), each oblique direction pressing part 12 has the rear end 12a used as the starting point of curvature.

  Further, as shown in the drawing, the oblique pressing unit 12 includes a high pressing unit 122 and a low pressing unit 121 (displayed in white) having a depression shallower than the high pressing unit 122 (displayed in black) formed around the high pressing unit 122. You may have. The low pressing part 121 may be formed so as to surround the entire high pressing part 122, and a part of the outline of the high pressing part 122 and a part of the outline of the low pressing part 121 may overlap. .

  The shape of the oblique direction pressing part 12 shown in FIGS. 6 to 8 is line symmetric. Therefore, the above-described inclined center line Y (a line that bisects the maximum angle β formed by the two virtual lines X1 and X2 that pass through the rear end 12a of the oblique compression unit 12 and touch the oblique compression unit 12) It is a symmetric line of the direction pressing part 12. However, the shape of the oblique direction pressing part 12 may not be line symmetric.

  In FIG. 9, the enlarged view of the diagonal direction pressing part 12 which has another shape is shown. In the form of FIG. 9, the oblique compression unit 12 has a heart shape, but the heart shape itself is not line symmetric. When the shape of the oblique direction pressing part 12 is not line symmetric as in the form of FIG. 9, it is preferable that the region on the outer side in the width direction is larger than the line symmetric figure (FIG. 6 and the like).

  6 to 9, not only the rear end 12a of the oblique direction compressed portion 12 but also the front end 12b is disposed inside the front / rear direction compressed portion 11 when viewed in the width direction. May be outside the squeezed portion 11 in the front-rear direction. However, since both the rear end 12a and the front end 12b of the oblique direction compressed portion 12 are arranged inside the front and rear direction compressed portion 11 when viewed in the width direction, the oblique direction compressed portion is formed at the side portion of the front region F. It is possible to prevent the part 12 from hitting the skin and causing a sense of incongruity. In addition, the front end 12b of the diagonal direction pressing part 12 points out the front edge part of the inclination direction pressing part 12 on the above-mentioned inclination centerline Y. As shown in FIG.

  In the form of FIG. 1, a width direction pressing portion (front width direction pressing portion) 15 extending in the width direction is provided in front of the pair of front and rear direction pressing portions 11 and 11. By providing such a front width direction squeezing part 15, the groove-like squeezing part becomes a starting point of folding, and therefore, when wearing, the front region F of the absorbent article 1 is more directed toward the front side of the body. Can be easily bent. Moreover, the body fluid leakage to the front can be prevented by the front width direction pressing portion 15.

  The diagonal direction pressing part 12 may be connected to the front width direction pressing part 15 or may not be connected. However, as shown in FIG. 1 and the like, when the oblique direction compressed portion 12 and the front width direction compressed portion 15 are not connected and separated from each other, the body fluid diffuses along the front width direction compressed portion 15. , Can prevent leakage. In that case, it is preferable that the distance to be separated is 2.0 mm or more. Moreover, the distance to separate is preferable in it being 10 mm or less from the relationship with the folding by the front width direction pressing part 15. FIG.

  In addition, in the form of FIG. 1, the width direction pressing part (back width direction pressing part) 16 extended in the width direction is provided behind the pair of front-rear direction pressing parts 11 and 11. In this embodiment, the pair of front-rear direction pressing parts 11, 11 are respectively connected to the front width direction pressing part 15 at the front side, and connected to the rear width direction pressing part 16 at the rear side. Thereby, the cyclic | annular groove-shaped pressing part is formed. Thus, by forming the connected compressed parts, it is possible to prevent leakage of bodily fluid mainly discharged to the bodily fluid discharge port corresponding region 20 in all directions.

  In the above, although the case where the diagonal direction pressing part 12 was formed only in the front area | region F was demonstrated, the diagonal direction pressing part 12 may be formed also in the back area | region R. FIG. In that case, a pair of 2nd diagonal direction pressing part formed in the back area | region R is arrange | positioned inside the front-back direction pressing parts 11 and 11 seeing in the width direction, and there exists an effect that it curves to a body according to roundness. As long as the pair of oblique compression parts 12 and 12 formed in the front region F may be the same shape, size and / or arrangement, or may be different.

  FIG. 10 shows an absorbent article 1A according to another embodiment of the present invention. 1 A of absorbent articles differ from the absorbent article 1 shown in FIG. 1 by the point from which the structure of a pressing part differs. The absorbent article 1 is formed with a pair of front and rear squeezing parts 11A and 11A, and in front thereof, oblique squeezing parts 12A and 12A that extend outward toward the front are provided. Furthermore, 2nd diagonal direction pressing parts 13A and 13A are formed in the back of a pair of front-back direction pressing parts 11A and 11A.
