Description

  The present invention relates to an absorbent article provided with a side sheet.

  The function of absorbent articles has improved in recent years. For example, technology development is progressing in absorbent articles such as sanitary napkins, panty liners, cage sheets, and incontinence pads, and some of them exhibit high functions. Specifically, the technology has been supported by the development of new materials, the improvement of the shape of articles, the development of processing equipment, and the like, and the performance such as the wearability of the articles, the liquid absorbability and the liquid retainability has been improved. And the technique which industrially produces an absorbent article also progressed and the cheap thing which can be disposable by mass production has been developed although it is highly functional as mentioned above.

  While such improvements in functionality are advancing, the appearance of the article is only brought about by the function, and it cannot be said that the design is sufficiently considered. However, soft and warm impressions are preferred for such articles that are often applied directly to the skin. Of course, it is not desirable to give a cold and hard impression. For example, there is a flap portion provided with a “lattice-like” recess (see Patent Document 1), and a flap base portion in which a top sheet and a side nonwoven fabric are fixed “linearly” (see Patent Document 2). Both are geometric patterns. Although there is what formed "leaf-like" embossing (refer to patent documents 3), since it processed into a surface sheet, the influence on liquid-leakage property by the penetration of a surface material layer, etc. cannot be ignored.

  In consideration of these matters, an absorbent article having a side sheet provided with an embossed pattern with high design has been developed (see Patent Document 4).

It aims at providing the absorbent article which can give beauty | look.

  The present invention includes an absorbent main body having a liquid-permeable surface layer, a liquid-retaining absorbent layer, and a leak-proof layer, and substantially the entire length of both side edges on the skin contact surface side of the absorbent main body. An absorbent article having a pair of left and right side sheets provided, the first emboss formed only on the side sheet, the side sheet, the surface layer, the absorbent layer, and the leak-proof layer of the absorbent main body The above-mentioned object is achieved by an absorbent article that is connected to any one of the layers and provided with second embosses formed in a row in the longitudinal direction of the side sheet continuously or intermittently. It is a thing.

  The absorbent article of the present invention maintains high performance in basic functional characteristics such as wearability, liquid absorbability, and liquid retention, and also improves side leakage prevention and anti-shrinkage, and the structure is decorative. It has an excellent effect that it can give a good impression to the user.

Hereinafter, the absorbent article of this invention is demonstrated, referring drawings for the sanitary napkin which is the preferable embodiment.
FIG. 1 is a plan view schematically showing a sanitary napkin (first embodiment) as a preferred form of the absorbent article of the present invention, with a part thereof broken. As shown in FIG. 1, the sanitary napkin 10 of Embodiment 1 includes an absorbent main body 4 having a liquid-permeable surface layer 1, a liquid-retaining absorbent layer 2, and a leak-proof layer 3, and the absorption. It has a pair of left and right side sheets 5 provided over substantially the entire length along both side edges on the skin contact surface side of the sex main body 4. The side part is formed integrally with the main body. The side sheet 5 is provided with a first emboss 6 formed only on the side sheet 5. Furthermore, the side sheet 5 is connected to any one of the surface layer 1, the absorbent layer 2, and the leak-proof layer 3 of the absorbent main body 4, and is functionally integrated to improve the function of the absorbent article. Two embossments 7 are provided. The second embosses 7 are provided in a row in the longitudinal direction of the side sheet 5.

  In the sanitary napkin 10 shown here, the surface layer (surface sheet) 1 covers the entire upper surface of the absorbent layer (absorber) 2 and extends slightly from the side edge of the absorbent layer 2. However, as shown in FIG. 2A, the surface layer 1 is preferably not in contact with the leak-proof layer (back sheet) 3. The leak-proof layer 3 covers the entire lower surface of the absorbent layer 2 and extends outward from the side edge of the absorbent layer 2. A substantially vertically long absorbent main body 4 is formed from the surface layer 1, the absorption layer 2, and the leak-proof layer 3.

  A pair of left and right side sheets 5 and 5 are provided over substantially the entire length along each side edge on each side edge on the skin contact surface side of the absorbent main body 4. Here, as shown in the figure, a pair of wings 11 formed from the leak-proof layer 3 and the side sheet 5 may be provided on both side edges of the central portion where the excrement of the absorbent main body 4 is concentrated. preferable.

  In the illustrated example, the leak-proof layer 3 and the side sheet 5 are joined by forming side seal portions 12 at both side edges of the absorbent main body 4 and the peripheral edge of the wing 11. Moreover, the surface sheet 1 and the leak-proof layer 3 respectively extend from the front and rear ends of the absorbent layer 2 and form an end seal portion 13 so as to be joined at the extended portion. The leak-proof layer 3 and the side sheet 5 are preferably joined by an adhesive (not shown).

  FIG. 2-1 is an enlarged cross-sectional view showing a cross section taken along line II-II shown in FIG. The form of the sanitary napkin 10 will be described in more detail with reference to FIG. The side sheet 5 is disposed up to the upper position (overlapping position) of the absorption layer 2 in the width direction. At the overlapping position, the side sheet 5 is preferably folded back at the sheet end and brought into contact with the surface layer 1 as illustrated. Here, it is preferable to join the folded portions 5x and 5y in the side sheet 5 with an adhesive. And it is preferable that the sanitary napkin 10 of Embodiment 1 is provided with a hot melt adhesive (not shown) provided on the non-skin contact surface of the absorbent main body 4 and the adhesive surface is fixed to the underwear. .

  In the sanitary napkin 10 of the first embodiment, the first emboss 6 is formed so as to join the folded portions 5x and 5y of the side sheet 5. Referring to FIG. 1, the first emboss may be provided by being partially unevenly distributed. However, as shown in the figure, the first emboss forms a row 6 y extending in the longitudinal direction of the side seat. It is preferable to provide as described above. That is, when a plurality of the first embosses are provided intermittently, the individual embosses are not separated too much, and the side of the liquid excreted in the central region of the absorbent main body 4 (the region sandwiched between the pair of the inner edges 5a of the side sheets). It is preferable to provide it close to the extent that the leakage prevention effect is exhibited. At this time, it is preferable to provide the first emboss in a continuous shape in order to further enhance the side leakage prevention effect.

  A second emboss 7 is further provided on the side sheet 5 of the sanitary napkin 10 according to the first embodiment. In the first embodiment, the second emboss 7 is provided at such a depth as to cover the thickness of the side sheet 5, the surface layer 1, and the absorption layer 2 as shown in FIG. And the 2nd emboss 7 with this depth is extended in the row 7y over the longitudinal direction of the side seat | sheet 5 (refer FIG. 1). More specifically, each second emboss has a substantially S-shaped form in a plan view. The individual embosses are not continuous but are provided independently, but are not separated from each other, and are kept in a separated state so as to form a row and substantially exhibit a liquid side leakage preventing action. .

  In the sanitary napkin of the first embodiment, both the first emboss and the second emboss form a row extending in the longitudinal direction of the side seat 5, and both are provided in parallel with each other. Thus, by arranging the first embossed row 6y and the second embossed row 7y in combination in parallel, the liquid flow is more effectively blocked by the interaction of both embossed rows, and the Leak prevention function can be demonstrated. For example, in the first embodiment, since the absorption layer 2 is partially consolidated by the second embossing, there is an effect of temporarily reducing the propagation speed of the liquid transmitted through the absorption layer 2. As a result, the liquid can be blocked at that site. The second emboss 7 first blocks the liquid that is transmitted to the outer side of the article in the width direction (X direction) of the article, and a small amount of leaching occurs while diffusing in the side sheet beyond that. Further, the first emboss 6 can reliably block the liquid.

  In the first embodiment, since the deep second emboss 7 is provided in the vicinity of the inner edge 5a of the side seat along the inner edge 5a, the inner edge 5a is moderate as shown in FIG. It has a leak-proof wall structure that holds the space 21 opened toward the central region of the absorbent main body. Thereby, in addition to the side leakage preventing action described above, it is possible to block the liquid transmitted on the article surface more effectively. Specifically, for example, even when a person with a slightly different body shape wears or when an article is slightly displaced due to exercise, the standing state of the inner edge 5a is appropriately changed to fit, High liquid leakage prevention property can be realized.

  Here, in the sanitary napkin 10 of the first embodiment, it is preferable to form the first emboss and the second emboss in the region 22 where the absorbent layer 2 of the side sheet 5 exists below (see FIG. 2-1). ). By doing in this way, the favorable curvature of a longitudinal direction and the side leakage prevention property of the sanitary napkin at the time of mounting | wearing are maintained. And it is preferable to arrange | position a 1st embossing on the outer side of a 2nd embossing.

  Next, the shape (refer FIG. 1) in the top view of a 1st emboss and a 2nd emboss is demonstrated in more detail. In the sanitary napkin of the first embodiment, as shown in the figure, the first emboss 6 includes a curved emboss 6a and a hollow emboss 6b. And they are combined and arranged so as to be substantially continuous in the longitudinal direction without being continuous in the plan view. Here, “in the plan view, it is substantially continuous in the longitudinal direction (hereinafter, unless otherwise specified, this continuous state is also simply referred to as“ substantially continuous ”)” This means that when the emboss is projected in a direction orthogonal to the longitudinal direction (X direction), the projected image is continuous in the longitudinal direction (Y direction). By setting it as the form of such an embossing row | line | column, favorable lateral leakage prevention property can be exhibited. And it is preferable to provide the substantially continuous state of an emboss row | line | column over 50% or more of the full length of the longitudinal direction of an absorptive main body, and it is more preferable to provide over substantially full length.

Regarding the embosses 6 a and 7, it has a shape that crosses two or more straight lines along the longitudinal direction of the side sheet 5, that is, a substantially S-shape. By forming such gently curved embosses in a discontinuous state, the stress for bending is moderately dispersed and the embosses themselves are less likely to become wrinkles. For this reason, bending stress is unlikely to occur in the longitudinal direction of the side sheet, and it can be softly brought into contact with the skin in a bent state. Furthermore, such a substantially wavy line-shaped embossed row disperses wrinkles in parts other than the embossed parts, and hard wrinkles are difficult to be formed in the embossed parts. Is good. Moreover, since the embossed pattern is formed in the side sheet 5, it is hard to get wrinkles also in the surface layer 1, and can implement | achieve a more favorable touch.
Each emboss 6a or 7 is gradually narrowed toward the both end portions. By using such a shape, it is possible to bend at the thin portions at both end portions of the emboss, and to prevent a portion with a wide emboss width from being raised, thereby increasing flexibility.

  The hollow emboss 6b having a hollow shape in the first embodiment is an emboss having a non-embossed portion on the inner side in a plan view and forming a planar region embossed around the non-embossed portion. A plurality of hollow embosses 6a are gathered to form a petal-shaped emboss pattern. In the area where the hollow emboss is provided, the embossed portion does not rise, and the hollow area is softly raised, so that it is possible to obtain a liquid propagation preventing effect by the emboss without reducing the flexibility. .

  The floral pattern formed by the above-described hollow emboss 6b is combined with the vine-shaped emboss pattern formed by the substantially S-shaped emboss 6a or 7 described above, and has a decorative aesthetic appearance. Is given. In addition, by arranging the predetermined embosses in a predetermined pattern in this way, an interaction due to each shape, that is, a soft bending state in the longitudinal direction of the absorbent article is realized, thereby improving the touch of the side sheet. It is possible to improve the leak-proof property of the side edge portion of the absorbent layer by the side sheet.

In addition to the shape of the embossed plan view, a plurality of substantially S-shaped embosses are superimposed, for example, an emboss having 3 to 5 end portions, or an emboss formed so that the central portion gradually becomes thinner. Also good. In this way, flexibility may be maintained to prevent wrinkles, design characteristics may be changed, and touch and leakage resistance may be improved.
Note that the embossing and its rows may have straight portions. Moreover, an elastic body can be arrange | positioned in the inner edge 5a of the side seat | sheet 5, and a gather can also be formed there.

  Although the constituent material of the surface layer 1 is not specifically limited, It is preferable to use a hydrophilic nonwoven fabric. Although the constituent material of the leak-proof layer 3 is not specifically limited, It is preferable to use a leak-proof film sheet. As the absorption layer 2, a normal absorbent material can be used. Examples of the side sheet include a nonwoven fabric, a film sheet, and paper. From the viewpoint of leakage prevention, the side sheet is preferably formed of a liquid non-permeable or hardly permeable hydrophobic nonwoven fabric, a leakage-proof film sheet, or the like. Each layer and side sheet of the absorbent main body may be a single sheet, or may be combined with a functional sheet or the like to form two or more sheets. When each layer or side sheet is constituted by a plurality of sheets, the second emboss may be provided so as to join all of the plurality of sheets, or may be provided only on a part of the sheets. For example, the second embossing is provided on the side sheet and any layer of the absorbent main body, but a part of the plurality of sheets constituting the side sheet and a part of the plurality of sheets constituting each layer are integrated. What was provided with the form to do is also included in this invention. Further, when the side sheet is composed of a plurality of sheets, the first emboss may be provided on only one of the sheets constituting the side sheet, or may be provided so as to join the plurality of sheets. good.

  The formation method of the first embossing and the second embossing is not particularly limited, and if it can be formed in a desired shape, even if it is indentation pressure bonding that densifies the member, heat fusion (heat sealing) that joins the members It may be. Speaking of a specific forming method, for example, a long member forming the side sheet 5 is prepared, and first embossing is previously formed thereon. The long members are joined to both side edges of the absorbent main body 4 by forming side seals 12, the front and rear end portions are shaped into a predetermined shape, and the end seal portion 13 is formed. Side sheets 5 having first embosses on both side edges are provided. Thereafter, for example, the second embossing can be provided by thermocompression bonding from above the side sheet 5 to a predetermined depth and integrating with the surface layer 1 and the absorption layer 2.

  Here, it is preferable that the emboss depth is deeper than the first emboss. In the present invention, the embossing depth refers to the distance from the sheet surface of the embossing opening to the bottom of the embossing. In the enlarged sectional view of the embossing portion shown in FIG. 2-2, the depth of the first embossing is 6d. Yes, the depth of the second emboss is 7d. In the present invention, this depth relationship is preferably 7d> 6d.

  By making the first embossing shallower in this way, it is possible to obtain an emboss having a complicated plan view shape that is difficult to process with a deeper one. Thereby, it can be set as the decorative embossing with high design property. And by deepening the second embossing, for example, even if the first embossing is shallow and itself is not sufficiently conspicuous, the second embossing effectively draws the viewer's attention and impresses the decorative aesthetics more strongly be able to. Furthermore, the deep second embossing has a functional aesthetic appearance that is excellent in liquid side leakage and gives the impression. Then, while deepening the second emboss to make the shadow stand out and combining it with the shallow first emboss, on the other hand, it is possible to realize a high-quality and high-quality appearance without giving a too hard impression. It can also maintain a good texture. That is, the combination of the shallow first emboss and the deep second emboss realizes an interaction that cannot be obtained by only one of them.

In the sanitary napkin of the first embodiment, for example, the first emboss depth 6d is preferably about 0.1 to 2.0 mm, and the second emboss depth 7d is about 0.5 to 10 mm. It is preferable. The difference between the depth 7d and the depth 6d is not particularly limited, but the difference is preferably set to 0.5 mm or more from the viewpoint that the embossing is sharpened to give the appearance beautifully.
As a material for forming the absorbent layer 2, those used for absorbent articles such as sanitary napkins, panty liners, incontinence pads and the like can be used without particular limitation. What used these together can be used preferably. As the fibers constituting the fiber assembly, hydrophilic natural fibers such as pulp fibers, synthetic fibers (preferably subjected to hydrophilic treatment), and the like can be used. In the sanitary napkin of Embodiment 1, it is desirable that the absorbent layer 2 is bulky and the basis weight of the fiber assembly is high from the viewpoint of increasing the depth of the second emboss, Since the embossed part is excessively cured, there is a concern that the wearability is deteriorated. The basis weight preferably ^{150g / m 2 ~500g / m 2} .

Figure 3 is a plan view schematically showing a sanitary napkin (embodiment 2) of the form of reference example of the intake Osamusei article. 4 is an enlarged cross-sectional view showing a cross section taken along line IV-IV shown in FIG.
In the second embodiment, the second emboss is provided outside the first emboss, and the second emboss is provided so as to connect the side sheet 5 and the surface layer 1. By doing in this way, favorable liquid-leakage prevention property can be exhibited in the aspect different from the thing of this Embodiment 1. FIG. That is, in the sanitary napkin 20 of the second embodiment, the liquid propagating on the surface can be blocked more effectively. For example, it is possible to first stop the liquid transmitted through the surface with the first emboss 6, and still more reliably stop the liquid spreading through the article surface with the second emboss 72. In particular, in the second embodiment, since the deep second emboss 72 is provided on the outer side of the article and at or near the end of the surface layer 1, the amount of liquid excretion is large and the interface 42 between the side sheet 5 and the surface layer 1 is present. The liquid leakage prevention function can be effectively exhibited when the liquid propagates to Further, by fixing the end portion of the surface layer 1 or the vicinity thereof, the shape stability (prevention of shape loss) when the article is deformed is enhanced.

Although the formation method of the 2nd embossing in this Embodiment 2 is not specifically limited, For example, the 1st embossing 6 is formed in the side sheet 5, and it is set as the composite sheet which joined the surface layer 1. FIG. The second emboss 72 can be provided by integrating the surface layer and the side sheet 5 by thermocompression bonding at a predetermined position of the composite sheet. The composite sheet (surface layer 1, side sheet 5) provided with the first and second embosses is superposed on a separate combination of the leak-proof layer 3 and the absorbent layer 2, and the necessary portions are joined for sanitary use. The form of the napkin 20 is obtained.
The depth of the second emboss 72 (not shown in FIG. 4 but defined in the same manner as that shown in FIG. 2-2) is not particularly limited, but should be deeper than the first emboss 6. For example, it is preferable to set it as 0.2-4.0 mm.

The arrangement in the longitudinal direction of the first emboss 6 and the second emboss 72 of the second embodiment, the shape characteristics in the plan view, and the advantages thereof are the same as those in the first embodiment.
The inner edge 5a of the side sheet may be in a floating state without being joined to the absorbent main body, but when there is a sense of incongruity due to twisting when contacting the skin, for example, the interface 41 between the side sheet 5 and the surface layer and 42 may be joined by an adhesive.
As the surface layer 1, those used for absorbent articles such as sanitary napkins, panty liners, incontinence pads and the like can be used without particular limitation, but in the sanitary napkin of Embodiment 2, the second embossing is used. From the viewpoint of increasing the depth, it is desirable to have a bulky structure, such as an air-through nonwoven fabric. It is also possible to use a method of increasing the apparent thickness of the sheet by sheet processing such as hole opening processing or uneven processing.

FIG. 5 is a plan view schematically showing a sanitary napkin (third embodiment) as still another preferred embodiment of the absorbent article of the present invention. 6 is an enlarged sectional view showing a section taken along line VI-VI shown in FIG.
In the third embodiment, the second emboss 73 is provided outside the first emboss 6 and further outside the surface layer 1. And in this Embodiment 3, the 2nd embossing 73 is provided so that the side seat 5 and the leak-proof layer 3 may be connected. By doing in this way, in this Embodiment 3, especially when there is much excretion liquid volume and not only propagates on the surface, but the inside of the absorption layer 2 moves and the liquid leaks However, the liquid can be effectively blocked. Specifically, the liquid transmitted through the surface is blocked by the first emboss 6, but the liquid that still leaks or the liquid that leaks from the absorption layer 2 can be reliably stopped by the second emboss 73. In particular, since the second emboss 73 is provided on the outer side of the surface layer 1, the liquid leakage prevention function can be exhibited particularly when the liquid spreads significantly to the space 63 due to the wet spread of the liquid. .

Although the formation method of the 2nd embossing 73 in this Embodiment 3 is not specifically limited, For example, the 1st embossing 6 is formed in the side sheet 5, and it is set as the composite sheet joined to the leak-proof layer 3. FIG. A second emboss 73 can be provided by integrating the side sheet 5 and the leak-proof layer 3 at a predetermined position of the composite sheet by thermocompression bonding. The composite sheet (side sheet 5 and leak-proof layer 3) provided with the first and second embosses is superposed on a combination of the surface layer 1 and the absorbent layer 2 separately, and the necessary portions are joined together. The form of the napkin 30 for use is obtained.
The depth of the second emboss 73 (not shown in FIG. 6 but defined in the same manner as that shown in FIG. 2-2) is not particularly limited, but is deeper than the first emboss 6. For example, 0.2 to 3.0 mm is preferable.

The arrangement of the first emboss 6 and the second emboss 73 in the third embodiment in the longitudinal direction, the shape characteristics in the plan view, and the advantages thereof are the same as those in the first embodiment.
The inner edge 5a of the side sheet may be in a floating state without being joined to the absorbent main body. However, when there is a sense of incongruity due to twisting when contacting the skin, the inner edge 5a is joined with an adhesive at the interfaces 61 and 62, for example. May be.
As the leak-proof layer 3, those used in absorbent articles such as sanitary napkins, panty liners, incontinence pads and the like can be used without particular limitation, and the above high effects can be exhibited regardless of the material. .

  In the absorbent article of this invention, it is good also as a form which combined this Embodiment 1, 2, and 3 further. That is, it is good also as a form which provided the 1st embossing in the side seat | sheet 5, and also combined the 2nd embossing 7 (FIG. 1), 72 (FIG. 2), and 73 (FIG. 3) suitably. Among these, a combination of Embodiments 1 and 2, that is, a form in which the first emboss is arranged so as to be sandwiched between the second emboss 7 (FIG. 1) and the second emboss 72 (FIG. 2) is preferable. This combination is preferable in that interaction between liquid leakage prevention and twist prevention can be obtained by combining a plurality of types of second embosses without excessively concentrating embossing and giving a hard impression.

  In the absorbent article of the present invention, it is preferable that the first embossing and the second embossing have different whiteness. By doing so, the light transmittance of both embossments can be made different from each other, and the visibility due to the shading effect of the unevenness can be enhanced. For example, the difference in light transmittance can be increased, and both can be made more impressive by combining a transparent embossing and a whitening embossing. In the case of making it transparent, depending on the type of sheet material, the fiber constituting the side sheet 5 can be heated and compressed to near the melting point or higher so as to lose the shape of the fiber and make it transparent. In the case of whitening, although depending on the type of the sheet material, it is also heat-compressed to such an extent that the shape of the fiber is not lost, or heat-compressed in the vicinity of the melting point of the sheath component of the core-sheath structure fiber, so that the shape of the fiber is partially Can be maintained and whitened to make it whiter than the periphery of the embossed portion. When it is made transparent, it is preferable not only because of high visibility, but also because it is excellent in bondability with other materials such as side sheets or top sheets, and leakage resistance can be further improved. When whitened, the visibility is further enhanced, and a pattern formed by the surrounding embossing or its aggregate can be formed, which is preferable.

  In the absorbent article of the present invention, it is preferable that the first embossment and the second embossment have different hardnesses. Which emboss is to be made harder may be appropriately determined according to the required performance, emboss depth, etc. For example, the second emboss is preferably made harder. Thus, by making the first emboss and the second emboss different in hardness, when the stress applied by the deformation of the absorbent article is applied, the inflection point of the stress from the elastic deformation to the plastic deformation is divided into two stages. Can be provided. For this reason, the deformation | transformation which follows a body becomes possible with respect to a weak stress and a strong stress, and the absorbent article excellent in the mounting property can be provided, which is preferable.

  In addition to sanitary napkins, the absorbent article of the present invention can also be applied to panty liners, cage sheets, incontinence pads, and the like. In particular, it can be favorably applied to absorbent articles having a thickness of 2 mm or more, a length of 150 mm or more, and a width of 50 mm or more.
