A raised absorbent article is disclosed.

JP 2004-154153 A JP 2001-95843 A

Both of the absorbent articles described in Patent Document 1 and Patent Document 2 include an absorbent body having a middle-high portion as a constituent member. When the middle and high parts are provided in the absorbent body, the number of members of the absorbent body is increased, the number of manufacturing steps is increased, and the labor and cost of manufacturing the absorbent article are increased. Furthermore, the absorbent article described in Patent Document 2 has the middle and high portions raised by the contraction force of the three-dimensional gather sheet, and the three-dimensional gather sheet having elasticity is also a constituent member.
In the absorbent article described in Patent Document 2, the medium-high absorbent body is contracted inward in the longitudinal direction due to the contraction force of the three-dimensional gather sheet, wrinkles are generated in the width direction of the absorbent body, and body fluid is generated in the wrinkles. There is a possibility of side leakage along.

  Accordingly, an object of the present invention is to provide an absorbent article that is easy to manufacture because the absorbent body bulges toward the skin when worn, has an excellent fit.

  The present invention is an absorbent article provided with an absorbent layer and a leak-proof layer, wherein a pair of grooves are provided on both sides in the longitudinal direction of the skin contact surface side of the absorbent layer, and the pair of grooves, The absorbent layer has a substantially line-symmetric shape with respect to a center line extending in the longitudinal direction, and each of the pair of grooves is formed to be convexly curved outward in the width direction in the central region in the longitudinal direction. Further, each of the pair of grooves has a portion that extends from the longitudinal central region to the front part or / and the rear part and is constricted inward in the width direction in at least one of the front and rear of the longitudinal central region. And the said objective is achieved by providing the absorbent article folded | folded by the fold line which straddles the width direction in this narrowed part.

  According to the absorbent article of the present invention, the absorbent body bulges toward the skin when worn, has excellent fit, and is easy to manufacture.

  Hereinafter, preferable this embodiment of the absorbent article of this invention is described, referring FIGS. 1-6.

The absorbent article of the present embodiment is a sanitary napkin 1 and includes a liquid-retaining absorbent layer 10 and a liquid-impermeable leak-proof layer 11 as shown in FIG. The absorbent layer 10 in the napkin 1 is composed of a liquid-permeable top sheet 2 and a liquid-retaining absorbent body 4, and the leak-proof layer 11 is composed of a liquid-impermeable back sheet 3. The pulp basis weight of the absorbent body 4 forming the absorbent layer 10 in the napkin 1 of the present embodiment is 300 to 600 g / m 2, which is a relatively large basis weight.
As shown in FIG. 1, the napkin 1 of the present embodiment is provided with a pair of grooves 5 and 5 that are embossed by heat seal processing on both side portions of the absorbent layer 10 on the skin contact surface side in the longitudinal direction. As shown in FIG. 2, the pair of grooves 5, 5 has a shape substantially axisymmetric with respect to the center line extending in the longitudinal direction and the center line extending in the width direction of the absorption layer 10. Each of the grooves 5 and 5 is formed to be convexly curved outward in the width direction in the central region in the longitudinal direction. Further, each of the pair of grooves 5 and 5 extends from the longitudinal central region to the front part A and the rear part C, and has portions 5D and 5E that are constricted inward in the width direction before and after the longitudinal central region. ing.
More specifically, each of the pair of grooves 5 and 5 is formed by connecting three portions 5A, 5B, and 5C that are convexly curved outward in the width direction in the longitudinal direction. Further, in the napkin 1 of the present embodiment, the convexly curved portion 5B located in the middle of the longitudinal direction includes the front part A in the longitudinal direction and the excretory part facing part B (the central region in the longitudinal direction). It is arranged in the excretion part facing part B when the excretion part opposing area | region arrange | positioned facing a wearer's liquid excretion part is divided into the width direction center) and the rear part C.
Further, the napkin 1 of the present embodiment has two widths positioned between the portions 5A, 5B, and 5C that are convexly curved outward in the three width directions in each of the pair of grooves 5 and 5 before use. Fold lines S1 and S2 (see FIG. 2) that cross each of the portions 5D and 5E confined to the inner side in the width direction are folded in three as shown in FIG.

  The napkin 1 of the present embodiment will be further described. The top sheet 2 and the absorbent body 4 are joined by the pair of grooves 5 and 5 respectively. As shown in FIG. 2, each of the pair of grooves 5 and 5 is provided so that the napkin 1 extends from the front part A through the excretory part facing part B to the rear part C in the longitudinal direction. Further, as shown in FIG. 4, each of the pair of grooves 5 and 5 is formed to extend deeply in the thickness direction of the napkin 1 to the vicinity of the back surface side of the absorbent body 4, and a large amount of body fluid is excreted. However, since the body fluid is temporarily stopped not only by the skin contact surface but also by the groove 5, it can also move to the absorbent body 4 through the groove 5.

The pair of grooves 5 and 5 will be described in detail. The pair of grooves 5 and 5 are connected and closed at the front part A and the rear part C of the absorbent layer 10 as shown in FIG. Therefore, when the napkin 1 receives compressive force from the width direction at the time of wearing, it is effectively prevented that the napkin 1 is folded in two along the longitudinal direction at the center portion in the width direction.
In addition, the seal portion forming the pair of grooves 5 and 5 is connected to the front portion A with a sharp shape toward the front, and has a sharp shape toward the rear at the rear portion C. Have and be connected. Therefore, the width of the groove in the front-rear direction (length in the longitudinal direction) increases as the high basis weight absorber is used, and the touch may be lowered, but the napkin 1 of the present embodiment has a high basis weight. The absorbent body 4 and the surface sheet 2 can be joined by a narrow seal portion, and the touch can be kept good.

In the napkin 1 of the present embodiment, the central portion of the absorbent body 4 surrounded by the pair of grooves 5 and 5 described above is raised toward the skin direction when the napkin 1 receives a compressive force from the width direction when worn. A raised portion 40 is formed. In addition, the protruding part 40 before wearing does not protrude, but has a substantially uniform absorbent basis weight.
As shown in FIG. 2, the raised portion 40 has a substantially line-symmetric shape with respect to the center line extending in the longitudinal direction of the napkin 1 and the center line extending in the width direction. Further, the protruding portion 40 is formed with three portions curved in a convex manner on both outer sides in the width direction, and is formed in the front portion A, the excretory portion facing portion B, and the rear portion C. The portions 40A, 40B, and 40C that are convexly curved outward are provided. Between the part 40A and the part 40B and between the part 40B and the part 40C, two parts 40D and 40E that are confined inward in the width direction are formed, respectively.

  In the raised portion 40, both side edges of the portion 40A are formed from the portions 5A and 5A of the pair of grooves 5 and 5, as shown in FIG. 2, and both side edges of the portion 40B are The grooves 5 and 5 are formed from the portions 5B and 5B. Both side edges of the portion 40C are formed from the portions 5C and 5C of the pair of grooves 5 and 5.

In the raised portion 40 of the napkin 1 of the present embodiment, the width W1 (the maximum width along the width direction in the longitudinal direction) of the portion 40B of the excretory portion facing portion B is, as shown in FIG. Each of the portions 40A and 40C in the portion C is wider than the width W2 (the maximum width in the longitudinal direction along the width direction). Moreover, the length L1 along the longitudinal direction of the part 40B of the excretory part facing part B is a length along the longitudinal direction of the parts 40A and 40C in the front part A and the rear part C, as shown in FIG. It is longer than L2.
The said part 40B of the protruding part 40 which has such a shape contact | abuts so that a wearer's excretion part may be covered over a longitudinal direction and the width direction at the time of wear of the napkin 1. FIG.

Moreover, the napkin 1 of this embodiment is folded in three in the state of a product, as shown in FIG. Since the napkin 1 is folded at the two constricted portions 5D and 5E of the pair of grooves 5 and 5 at the folding lines S1 and S2 extending across the width direction, the napkin 1 is easily folded and is formed by the folding lines S1 and S2. The generation of wrinkles is minimized.
When the napkin 1 is used, the tab tape 8 is removed, and each of the folded front part A and rear part B is opened outward in the longitudinal direction. In the raised portion 40 of the napkin 1 developed in this manner, the marks of the fold lines S1 and S2 straddling the two constricted portions 40D and 40E in the width direction remain as wrinkles.

Next, the state in which the napkin 1 of the present embodiment is worn will be described below.
The napkin 1 is fixed and worn on the inner side of the crotch such as shorts, and the portion of the topsheet 2 in the excretory part facing part B of the napkin 1 comes into contact with the excretion part of the wearer. At this time, as shown in FIG. 5, the napkin 1 receives a compressive force from the left and right in the width direction (in the direction of the arrow in FIG. 5) by the inner sides of the thighs of the wearer.
When the napkin 1 receives a compressive force from the left and right inward in the width direction, the napkin 1 is shown in FIG. 5 starting from the wrinkles of the fold lines S1 and S2 that straddle the two constricted portions 40D and 40E in the raised portion 40 in the width direction. Thus, the whole protruding part 40 protrudes toward the skin side with the surface sheet 2.
More specifically, in the portion 5B forming both side edges of the raised portion 40 in the excretory portion facing portion B, the portion located on the outermost side in the width direction quickly receives the compressive force toward the inner side in the width direction, The compressive force is transmitted over the entire longitudinal direction of the groove 5 to cause the raised portion 40 to be raised.
When the raised portion 40 of the absorbent body 4 in the napkin 1 is raised toward the skin side, the surface sheet 2 positioned on the raised portion 40B is pressed against the excretion portion of the wearer and is in close contact with the skin. Furthermore, since the groove is formed in a sharp shape at the end in the longitudinal direction, the ridge is narrowed inside the groove, so that the fit with the body is improved, and it is hardly affected by the bulge outside the groove. The absorber becomes flat and has the advantage of increasing the liquid stopping effect.

  The degree of the central bulge varies depending on the state of the shorts that fix the napkin 1 attached to the body, but in the present invention product, the bulge is higher than before because the width of the central (excretion point) is widened. Even if it is a case of underwear with small fit with a body, the absorption surface of a napkin can be effectively fitted to an excretion point.

In the state where the raised portion 40 is raised, both the front side and the back side of the raised portion 40 of the absorber 4 are convexly curved toward the skin side as shown in FIG.
Moreover, when the protruding part 40 protrudes toward the skin direction, the surface sheet 2 positioned on the protruding part 40 is also curved convexly toward the skin side as shown in FIG. The wrinkles of the fold lines S1 and S2 in each of 40D and 40E are extended and substantially disappear.

As shown in FIG. 2, a groove 6 that is convexly curved inward in the width direction is provided on the outer side in the width direction of each of the pair of grooves 5 and 5. Each of the pair of grooves 6 and 6 is formed by embossing by heat sealing, and the top sheet 2 and the absorbent body 4 and further an inner sheet 7 described later are joined by the grooves 6. The length of each of the pair of grooves 6 and 6 (the length along the longitudinal direction of the napkin 1) is substantially the same as that of the groove 5, and as shown in FIG. It extends to the middle of the absorber 4.

As shown in FIG. 4, a pair of water-repellent inner sheets 7 and 7 are arranged on the back surfaces of both sides of the absorbent body 4 of the napkin 1 of the present embodiment. The side portions on the outer side in the width direction of each inner sheet 7 extend from the side edge of the absorbent body 4 and are wound up between the absorbent body 4 and the top sheet 2. 2 and the absorber 4 are joined by the groove 6. Furthermore, the absorbent body 4 is substantially wrapped by the water-repellent inner sheet 7 and the back sheet 3 by arranging the back sheet 3 on the non-skin contact surface side, and the absorbed body fluid is exposed to the outside. Leakage is prevented.
Moreover, as shown in FIG. 4, the inner sheet 7 is bonded to the absorbent body 4 and the top sheet 2 by an adhesive on both sides in the longitudinal direction on the back side of the napkin 1. In addition, instead of using the water-repellent inner sheet 7, a flap portion can be formed by extending and joining the back sheet 3 and the top sheet 2 from both side edges of the absorbent body to the outside in the width direction, thereby enhancing the leakage prevention effect. .

The napkin 1 of the present embodiment will be further described. Both side portions in the longitudinal direction of the top sheet 2 extend from both side edges of the absorbent body 4, and are wound down between the inner sheet 7 and the back sheet 3, The back sheet 3 is joined. Moreover, it is preferable that the part located on the protruding part 40 in the surface sheet 2 is provided with the some hole from a viewpoint of making the permeability | transmittance of the excreted bodily fluid favorable.
Both end portions in the longitudinal direction of the top sheet 2 and the back sheet 3 extend from both end edges in the longitudinal direction of the absorber 4 and are joined by a known joining method such as heat sealing.
Moreover, the slip prevention material for fixing the napkin 1 to a wearer's shorts etc. is apply | coated to the outer surface of the back surface sheet 3. The slip stopper is covered with a release paper and is protected until use.

In the napkin 1 of the present embodiment, the length L1 along the longitudinal direction of the portion 40B of the raised portion 40 in the excretory part facing part B is 50 to 100 mm from the viewpoint of contacting the excretion part in the longitudinal direction. Preferably, it is 60-80 mm. Moreover, 20-70 mm is preferable and, as for the length L2 along the longitudinal direction of each said part 40A and 40C of the protruding part 40 in the front part A and the rear part C, it is more preferable that it is 30-60 mm. The length along the longitudinal direction is a length along a direction parallel to the longitudinal direction, and is not a length along a curved curve.
The width W1 (the maximum width along the width direction in the longitudinal direction) of the raised portion 40 in the excretory part facing part B is preferably 20 to 70 mm from the viewpoint of contacting the excretion part in the width direction, More preferably, it is 30-60 mm. Further, the width W2 (maximum width along the width direction in the longitudinal direction) of the portions 40A and 40C of the raised portion 40 in the front part A and the rear part C is preferably 10 to 60 mm, and preferably 20 to 50 mm. More preferred. The width along the width direction is a width along the direction parallel to the width direction (hereinafter the same).

In the napkin 1 of the present embodiment, various pulp materials used in conventional absorbent articles and the like can be used as the pulp material of the absorbent body 4, and in particular, softwood pulp, chemically treated synthetic pulp Long fibers such as cellulose tow are preferred. Further, as a material for forming the absorbent body 4, in addition to a pulp material, a polymer-absorbing polymer, a synthetic fiber made of polyester or polypropylene, a heat-fusible fiber, or rayon can also be used. As a material for forming the absorbent body 4, it is also preferable to use a mixture of pulp material and other materials.
The basis weight of the absorbent body 4 is as described above, but is preferably 200 to 800 g / m 2 from the viewpoint that the absorbent body rises well on the skin side and ensures the flexibility of the absorbent body. More preferably, it is ˜600 g / m 2 .
As the inner sheet 7, various water-repellent sheet materials used in conventional absorbent articles and the like can be used, and a polyethylene sheet, polyethylene laminated paper, and SMS nonwoven fabric are particularly preferable.
As a material for forming the top sheet 2 and the back sheet 3, various sheet materials used in conventional absorbent articles and the like can be used without particular limitation.

According to the napkin 1 of this embodiment mentioned above, by providing a pair of groove | channels 5 and 5 in the absorption layer 10, the absorption layer 10 can be raised toward the skin side at the time of wear. The napkin 1 having such a configuration is easily manufactured.
In addition, since the basis weight of the absorbent body 4 of the napkin 1 is large and the front and rear ends of the pair of grooves 5 and 5 are closed and connected, the raised portion 40 is more easily raised.
Moreover, since the absorber 4 is integrally wrapped by the inner sheet 8 on both side portions and the back surface side in the longitudinal direction, the raised portion 40 is configured to be more easily raised.
Moreover, since the groove | channels 6 and 6 which are curving convexly are provided in a pair of width direction inside, when the napkin 1 receives the compressive force from the width direction locally, the said compressive force applied to this local part Is distributed over the entire longitudinal direction of the groove 6 and transmitted to the groove 5 that is convexly curved outward in the width direction, whereby the raised portion 40 is stably obtained.
Thus, in addition to the pair of grooves 5 and 5, the groove 6 is provided on the outer side in the width direction of each of the grooves, so that the compressive force on the inner side in the width direction received by the napkin 1 is not uniform left and right. However, the raised portion 40 is well raised toward the skin side.
Furthermore, since the periphery of the raised portion 40 is surrounded by the pair of grooves 5 and 5, the shape stability of the surface shape is enhanced, and the raised shape is stably maintained during wearing. .
The wrinkles formed on the fold lines S1 and S2 traces when the napkin 1 is deployed substantially disappear due to the bulging of the raised portions 40 when worn, so that the body fluid excreted on the surface of the napkin 1 is transmitted through the wrinkles. There is no risk of leaking in the width direction.

The absorbent article of the present invention is not limited to the above-described embodiment, and can be appropriately changed without departing from the gist of the present invention.
For example, each of the pair of grooves 5 and 5 in the present embodiment extends from the central region in the longitudinal direction to the front part A and the rear part C, but may extend to only one of them.
Further, each of the pair of grooves 5 and 5 has a portion confined in the width direction inside both the front and rear of the central region in the longitudinal direction, but at least one of the grooves 5 and 5 has a portion constricted in the width direction inside. good. In this case, it is also preferable that the end of the longitudinal direction not having the constricted portion is folded at a fold line so as to straddle the width direction.
In addition, each of the pair of grooves 5 and 5 is formed by heat sealing in the present embodiment, but may be formed by using other pressure bonding means such as ultrasonic sealing.
Furthermore, although the absorber 4 was formed only from the pulp in this embodiment, the granular or layered superabsorbent polymer may be contained.
The absorbent article of the present invention may be a sanitary napkin or an incontinence pad.
