Embossed patterns 71 and 72 having shapes different from those of the embossed lines 61 to 63 are provided.

More specifically, as shown in FIG. 2, the sanitary napkin 1 of the present embodiment includes a liquid-retaining absorbent layer A and a liquid-impermeable leak-proof layer B. It consists of a permeable top sheet 2 and a liquid-retaining absorber 4, and the leak-proof layer B consists of a liquid-impermeable back sheet 3. The absorber 4 is interposed between the top sheet 2 and the back sheet 3.
The topsheet 2 covers the entire upper surface of the absorber 4 and extends slightly from the side edge of the absorber 4, but is not in contact with the backsheet 3. The back sheet 3 covers the entire area of the lower surface of the absorber 4 and extends outward from the side edge of the absorber 4. As shown in FIGS. 1 and 2, a substantially vertically long absorbent main body C is formed from the absorbent layer A and the leak-proof layer B.

As shown in FIG. 1, a pair of left and right side sheets 5, 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 C. Yes. In addition, a pair of wings D are provided on both side edges at the position of the excretory part-facing part of the absorbent main body C. As shown in FIG. 2A, the wing D is formed from an outer portion of the back sheet 3 and an outer portion 5 </ b> C of the side sheet 5.
As shown in FIGS. 1 and 2, the back sheet 3 and the side sheet 5 are joined at both side edges of the absorbent main body C and the peripheral edge of the wing D to form a side seal portion E. Further, as shown in FIG. 1, the top sheet 2 and the back sheet 3 respectively extend from the front and rear ends of the absorber 4 and are joined at the extended portions to form an end seal portion F.

  As shown in FIG. 2, the back sheet 3 and the side sheet 5 are also joined by an adhesive (not shown) in a region near both side edges of the absorbent main body C and a region of the wing D. Further, the side sheet 5 is arranged up to the position above the absorber 4 inward in the width direction, where it is folded back outward in the width direction and in contact with the top sheet 2 and in contact with the back sheet 3. Yes. Here, the folded portions 5A and 5B in the side sheet 5, the contact portion between the side sheet 5 and the back sheet 3, and the contact portion between the side sheet 5 and the top sheet 2 are also joined by an adhesive. ing. The folded portions 5A and 5B in the side sheet 5 are also joined by seals with emboss lines 61 to 63 and component image embosses 71 to 77 (described later) which are also embossed patterns.

  The sanitary napkin 1 of the present embodiment is fixedly attached to the underwear by a hot melt adhesive (not shown) provided on the non-skin contact surface of the absorbent main body C and the wing D.

As shown in FIGS. 1 and 3, the side sheet 5 has a substantially wavy embossed pattern P combined with embossed lines 61 to 63 and a closed embossed pattern (described later) or a comprehensive embossed pattern combined with concrete embossed. The length of the side sheet 5 is 50% or more of the total length in the longitudinal direction.
“50% or more of the total length in the longitudinal direction” is not necessarily limited to 50% or more of the total length in the longitudinal direction by only one emboss line or emboss pattern P, closed emboss, and concrete emboss. The total length along the longitudinal direction of the emboss pattern P in which a plurality of emboss lines are combined and the overall emboss pattern in which closed emboss or concrete emboss is combined is 50% or more of the total length in the longitudinal direction of the side sheet 5. ing. If it is 80% or more, the leakage-proof property is improved, and it is more preferable.

  The “substantially wavy line shape” does not necessarily have the same amplitude and wavelength as long as it has a wavy line shape as a whole, that is, it indicates a wavy shape woven by a curve. In the present embodiment, the substantially wavy emboss pattern P in which the emboss lines 61 to 63 are combined is a plurality of emboss lines 61 that are discontinuous in the longitudinal direction of the side sheet 5 in plan view, as shown in FIG. , 62 and 63 are arranged so as to be substantially continuous in the longitudinal direction of the side sheet 5. In addition, the wavy line shape of each emboss line does not need to be the same.

  “Substantially continuous in the longitudinal direction” means not only when it is actually continuous in a plan view, but also when it is not continuous in a plan view but is close and orthogonal to the longitudinal direction in a plan view (width direction) This includes the case of crossing a curved embossed line when moving a virtual straight line in the longitudinal direction. As described above, the sanitary napkin has leakage resistance in the lateral direction by the curvilinear embossed line being substantially continuous in the longitudinal direction. “Having overlapping regions in the longitudinal direction” described later also has the same meaning.

Specifically, as shown in FIG. 3, the emboss lines 61 to 63 have a shape that crosses two or more straight lines along the longitudinal direction of the side seat 5, specifically, a substantially S-shape, Is not included.
Each emboss line 61-63 which comprises the substantially wavy line-shaped emboss pattern P is arrange | positioned so that it may have the area | region which overlaps in a longitudinal direction instead of continuing by planar view. Specifically, in the plan view, the emboss line 61 and the emboss line 62 slightly intersect and are continuous in the plan view, but the emboss line 62 and the emboss line 63 are not continuous. However, the emboss line 61 and the emboss line 62 overlap in the longitudinal direction by about one third of their length, and the emboss line 62 and the emboss line 63 overlap in the vicinity of their end portions. That is, the embossed lines 61, 62 and 63 are substantially continuous in the longitudinal direction to form an embossed pattern P that covers about one half of the entire length of the side sheet 5.

Each emboss line 61, 62, and 63 that forms the emboss pattern P is gradually narrowed toward both ends thereof.
Of the embossed pattern P composed of the embossed lines 61 to 63, the innermost part of the embossed pattern P may be arranged to be included within 10 mm in the width direction from the inner edge 5 </ b> D of the side seat 5 (see FIG. 2). Moreover, it is preferable that the width | variety along the width direction of the absorptive main body C is 3 mm or more.

  As shown in FIG.1 and FIG.3, the closed embossing 71 and 72 which is an embossed pattern is formed in the side part of the excretion part contact area | region (area | region contact | abutted to a wearer's excretion part) of the absorptive main body C. As shown in FIG. . Moreover, the closed embossing 71 and 72 which are embossed patterns are substantially continuous in the longitudinal direction with the embossing patterns P and P which move back and forth in the longitudinal direction. In the embossed pattern and the embossed pattern P, “substantially continuous in the longitudinal direction” not only means that the embossed pattern and the embossed pattern P overlap each other in the vicinity of the end in the longitudinal direction and are actually continuous in plan view. It also includes a case where the embossed pattern or the embossed pattern P is always crossed when moving in the longitudinal direction a virtual straight line that is not continuous in the planar view but is close and is orthogonal to the longitudinal direction (extending in the width direction) in the planar view. That is, the embossed pattern and the embossed pattern P have a region that overlaps in the longitudinal direction of the side sheet 5, whereby the embossed pattern and the embossed pattern P are substantially continuous in the longitudinal direction, and the embossed pattern A comprehensive emboss pattern is continuously formed from the pattern and the emboss pattern P over substantially the entire length of the side sheet 5 in the longitudinal direction.

  Specifically, in the region T where the embossed pattern P is not continuous in the longitudinal direction in plan view in the side sheet 5, the closed embossed 71 and 72 having a shape for filling and closing the region T as the embossed pattern. Is provided. The closed emboss is an emboss that forms a closed region so that the substantially wavy emboss pattern P is not intermittent in the longitudinal direction (so as to be substantially continuous in the longitudinal direction), and the closed emboss itself is also intermittent in the longitudinal direction. Do not emboss pattern. The closed emboss 71 is a petal-shaped emboss pattern, and six divided emboss units gather to form a closed emboss group of floral patterns. The closed emboss 72 is a bifurcated leaf-shaped emboss pattern.

These closed embosses 71 and 72 are configured to have a curved shape, thereby making it difficult for large wrinkles to be generated on the side seat 5 and reducing the touch. The large petal-shaped and bifurcated leaf-shaped embossed pattern in this embodiment also functions as a concrete embossed pattern.
The concrete emboss is a pattern of a meaningful pattern such as a plant, an animal, or a star, and the outer periphery of the emboss can be represented by a curve. Therefore, since wrinkles generated when the absorbent article is bent collide with the outer peripheral curve of the concrete emboss and finely disperse, the side sheet can be flexibly bent to make the surface softer.

Furthermore, according to the concrete embossing, it is possible not only to improve the leak-proof property but also to achieve both the improvement of the leak-proof property and the soft visual effect. The concrete embossing can be easily obtained by being divided and configured like a petal shape, and the shape can be easily lifted and visibility can be improved.
Furthermore, if the embossing is arranged by blocking the flow shape in the longitudinal direction formed by the substantially wavy embossing pattern, it is easy to collect viewpoints on the concrete embossing, and it is easy to give the user an image such as a feeling of comfort by the concrete embossing. be able to. By making the line density occupied per unit longitudinal distance higher than the adjacent substantially wavy line emboss pattern, it is possible to easily disperse wrinkles induced by concrete emboss, and by making fine soft wrinkles feel It can be made difficult to reduce. As described above, it is preferable to increase the line density because the number of wrinkles generated increases, it is easy to interfere with wrinkles generated near the adjacent substantially wavy embossed pattern, and the generation of wrinkles is easily suppressed.

In addition, by changing the shape or the like of the concrete emboss according to the type of the absorbent article, it becomes easy to recognize the type of the absorbent article, and if it is used even once, the relationship between the state after use and the concrete emboss is easily stored in the memory. It is possible to easily derive from experience as to when it is appropriate to use the period. That is, it becomes easy to select an absorbent article that matches a physiological situation that varies greatly among individuals.
In concrete embossing such as floral patterns, wrinkles do not enter the embossing itself because the outer periphery curve is folded back around the embossing, and it is combined with a substantially wavy line embossing pattern. As a result, wrinkles generated in the vicinity of the substantially wavy-shaped emboss pattern can be dispersed, and interference can be prevented and flexibility can be prevented from being hindered.

  The concrete embossing preferably has a concave portion that is concave in the cross-sectional direction with respect to the substantially wavy embossing pattern, so that when the wrinkles generated from the substantially wavy embossing pattern come into contact with the concrete embossing, the concrete embossing Since the wrinkles are taken in and dispersed in the concave portion of the emboss, it is difficult to become large wrinkles, and the effect of hardly reducing the touch is also obtained.

In the present embodiment, the emboss patterns P and P adjacent in the longitudinal direction are substantially continuous in the longitudinal direction via the closed embosses 71 and 72, and from the emboss pattern P and the closed emboss (component image emboss) 71 and 72. An emboss pattern that is substantially continuous over the entire length of the side sheet 5 in the longitudinal direction is formed.
In addition to the closed embossing 71 and 72 as shown in FIG. 3, the side seat 5 has a concrete embossing 73 to 77 adjacent to the embossing pattern P in the width direction. Other embossing is provided. In this way, by arranging the embosses so that they are discontinuous in plan view and substantially continuous in the longitudinal direction, the absorbent article can be bent softly in the longitudinal direction in the absorbent article, and the touch of the side sheet Of the side edges of the absorbent layer by the side sheet is excellent.

  There is no restriction | limiting in particular as a surface sheet, In this embodiment, the hydrophilic nonwoven fabric is used. There is no restriction | limiting in particular as a back surface sheet, The leak-proof film sheet is used in this embodiment. A well-known thing is used as an absorber. Examples of the side sheet include a nonwoven fabric, a film sheet, paper, and the like. From the viewpoint of leakage prevention, a liquid nonwoven fabric or a non-permeable hydrophobic nonwoven fabric, a leakage-proof film sheet, etc. are preferably used. In the form, a hydrophobic nonwoven fabric is used. One side sheet may be used, or two or more side sheets may be combined in order to further improve leakage resistance. Embossing for improving leakage prevention may be applied to two or more sheets, or may be applied to only some of the layers.

There is no restriction | limiting in particular in the formation method of the embossing lines 61-63, the closing embossing 71-72, and the concrete embossing 73-77, In this embodiment, it forms in the shape of a curve by heat sealing.
The embossed lines 61 to 63 or the closed embossed (component image embossed) 71 to 72 and the concrete embossed 73 to 77 are preferably surrounding embossed formed around the non-embossed portion. Explaining, as shown in FIG. 4, a deep embossed portion 61A that is deeply recessed is formed at the peripheral edge portion, and a shallow embossed portion 61B that is recessed shallower than the deep embossed portion 61A is formed inside the deep embossed portion 61A. It is preferable that The deep embossed portion 61A is a portion compressed to 20% or less (t1 / t0) of the material thickness, and the shallow embossed portion 61B is a portion compressed to 10 to 80% (t2 / t0) of the material thickness (however, t2 <T1).

In the present embodiment, as shown in FIG. 3, a long material U is used as the material of the side seat 5. This long material U has the same width as that of the side sheet 5 in the sanitary napkin 1 in a completed state. The embossed pattern P (embossed lines 61 to 63), closed embossed 71 to 72, and concrete embossed 73 -77 are formed in advance periodically (one period S).
This long member U is joined to both side edges of the absorbent main body C using an adhesive, the front and rear end portions are shaped into a predetermined shape, and end seal portions F are formed. The sanitary napkin 1 provided with the side seal 5 with the embossed pattern P on the edge can be easily obtained.

In the sanitary napkin 1 of the present embodiment, curved emboss lines 61 to 63 are arranged in the longitudinal direction on the side sheet 5, and a plurality of substantially wavy emboss patterns P are formed, and are adjacent in the longitudinal direction. Since the embossed patterns 71 and 72 having shapes different from the embossed lines 61 to 63 constituting the embossed pattern P are provided between the embossed patterns P and P, the absorbent article can be softly bent in the longitudinal direction, and the side There is little fall of the touch of the sheet | seat 5, and it is excellent in the leak-proof property of the side edge part of the absorption layer by the side sheet | seat 5. FIG.
In particular, since the embossed patterns 71 and 72 are formed on the side of the excretory part contact region of the absorbent main body C, the embossed pattern 71 is excellent in ease of bending in the excretion part contact region where the ease of bending is required. And 72, it is easy to align with the excretory part.

The embossed pattern has an embossed pattern P that moves back and forth in the longitudinal direction and a region that overlaps in the longitudinal direction of the side sheet 5, whereby the embossed pattern and the embossed pattern P are substantially in the longitudinal direction. And an overall embossed pattern is formed continuously from the embossed pattern and the embossed pattern P over substantially the entire length of the side sheet 5 in the longitudinal direction. Therefore, the propagation of the liquid transmitted through the non-woven side sheet 5 itself is stopped by the seal portion of the emboss pattern P, and the propagation of the liquid transmitted through the upper surface of the side sheet 5 is stopped by the recess of the emboss pattern P. Excellent leakage prevention at the side edge of the absorbent layer.
Further, when the sanitary napkin 1 is to be bent in the longitudinal direction, the embossing itself is unlikely to become wrinkles, so that the bending resistance in the longitudinal direction is difficult to work and can be bent softly. Furthermore, since the embossed pattern P is formed in a substantially wavy shape on the side sheet 5 and wrinkles are easily formed on portions other than the embossed surface, it is difficult to form hard wrinkles on the embosses themselves, and there are many soft wrinkles and the touch is reduced. It is hard to do.

When the emboss lines 61 to 63 have a shape that gradually becomes narrower toward both ends, the thick portions are unlikely to be raised and the flexibility is unlikely to decrease because the emboss lines 61-63 are bent at the narrow portions at both ends. Even in a region where the embossed pattern P is not continuous in the longitudinal direction in plan view, the adjacent embossed patterns P are connected via the closed embossed 71 and 72 (substantially continuous in the longitudinal direction). The leakage preventing effect of the side edge portion of the absorbent layer by the side sheet 5 is sufficiently obtained.
In the region where the closed embossing and the concrete embossing are provided, the embossed portion is not raised, and the closed region is softly raised, so that it is possible to obtain a liquid propagation preventing effect by the embossing without significantly reducing the flexibility.

The absorbent article of the present invention is not limited to the above embodiment, and can be appropriately changed without departing from the gist of the present invention.
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, the present invention can be favorably applied to absorbent articles having a thickness of 2 mm or more, absorbent articles having a length of 150 mm or more, and absorbent articles having a width of 50 mm or more.
In the emboss pattern, a substantially wavy emboss line having three or more end portions can be incorporated as a method for achieving leakage prevention and flexibility. By selecting such a line, the embossed area in the transverse direction of the absorbent article can be increased, and leakage resistance is improved without reducing the bendability of the absorbent article in the longitudinal direction and the touch of the side sheet. Can be made. The emboss pattern can also be formed by arranging a plurality of emboss lines with one inflection point.

The embossing line, the concrete embossing or the closed embossing can be formed in a curved shape as a whole by providing spot-like embossing so as to be adjacent to each other.
The side sheet and the surface sheet can be joined by an emboss line, concrete emboss or closed emboss.
When hollow embossing is adopted for embossing line, concrete embossing or closed embossing, the folded portions 5A and 5B of the side sheet 5 are joined at the deep embossed part, and the side sheets 5 are not joined at the shallow embossed part. You may make it perform a compression process in the range. According to such a joining form, a good joining strength can be obtained, and a joint-integrated part (deep embossed part) and a part subjected to compression processing (shallow embossed part) to the extent that a leak-proof effect can be expected As a result, a good leak-proof property can be obtained, and the number of joints that are likely to become hard can be reduced.

The aspect which provides concrete embossing in the area | region T where the embossing pattern P is not continuous in the longitudinal direction by planar view in the side seat | sheet 5 is not restrict | limited to the aspect shown in FIG.
The concrete emboss 81 shown in FIG. 5 is a conch-shaped emboss provided so as to be adjacent to the substantially wavy-shaped emboss pattern P (intermittently in the longitudinal direction), and forms an isolated region in plan view. It is.

  The concrete emboss 82 shown in FIG. 6 is a butterfly-shaped emboss, and the emboss pattern P moving back and forth in the longitudinal direction is an emboss that does not have an overlapping region in the longitudinal direction of the side sheet 5. When the embossed pattern P having a shape is formed so as not to be substantially intermittent in the longitudinal direction, it is an emboss that forms a planar region isolated in a plan view. By arranging the concrete emboss 82 in this way, it is easy to suppress the occurrence of wrinkles on the side sheet 5 and not only prevent a decrease in wearing feeling and a liquid leak-proof property but also a flat surface with the substantially wavy-shaped emboss pattern P. Since it is isolated in view, the visibility of the concrete emboss 82 is increased, and a good impression can be given to the user.

Another second sheet can be arranged on the back side of the top sheet. In that case, what is necessary is just to join any two sheets among a surface sheet, a side sheet, and a second sheet.
The emboss pattern may have continuous or intermittent linear portions. In that case, in order to sufficiently obtain the effect of easy folding, it is preferable that the linear portion (the total in the case of intermittent) is 50% or less or 5 cm or less of the total length in the longitudinal direction of the side sheet. .
An elastic body may be disposed on the inner edge 5D of the side sheet 5 to form a gather on the inner edge 5D.
