Patent Document 1: Japanese Patent Application Laid-Open No. 2006-34496

However, the above-described absorbent article has the following problems.

Since the rear flap portion of the absorbent article described in Patent Document 1 has a flap absorber, the stiffness tends to be higher than that of the configuration without the flap absorber. Further, since the embossed portion is provided in the rear flap portion, the rigidity of the rear flap portion tends to be further increased. In addition, a plurality of embossed portions are arranged in the width direction. Therefore, when the absorbent article is pushed inward in the width direction from the outside in the width direction by the wearer's legs or buttocks, the rear flap portion is hard to be deformed, and there is a possibility that an uncomfortable feeling occurs.

Further, since the rigidity of the rear flap is relatively high, there is a possibility that the rear flap is not appropriately arranged along the curve of the body. Therefore, the sanitary napkin does not fit into the body, leakage of the body fluid occurs, and there is a fear that the feeling of wearing is deteriorated. Further, since the rear flap portion is rigid, for example, in the case where wrinkles or folded marks are formed, there is a fear that the wrinkles or folding marks of the wearer come into contact with the wearer and the wearing feeling is deteriorated.

The wing portion 43 is configured to fold back toward the skin non-contact side of the wearer's undergarment. The flap portion (60) is located behind the wing portion (43). Fig. 1 shows the area RA of the wing in the longitudinal direction and the area RB of the flap in the longitudinal direction. The flap portion 60 in this embodiment is a region extending outward in the width direction from the body portion 2 and extends rearward from the rear side end portion of the wing portion.

The rear side end portion (rear inner side end portion 43RI described later) of the wing portion which is the front side end portion of the flap portion 60 is a portion located in the widest inward direction between the wing portion 43 and the flap portion 60 . The body portion 2 is a region inside the width direction of the front end portion of the flap portion 60 and the rear end portion of the wing portion.

Fig. 1 shows the region RC of the main body in the width direction, the region of the wing in the width direction, and the region RD of the flap 60. In the present embodiment, the main body portion is defined as the main body portion in the width direction between the wing portion 43 and the flap portion 60, as compared with the portion located in the widest inward side. However, the present invention is not limited to this configuration. For example, a region extending in the front-rear direction from the region where the main body absorbent body 30 is disposed may be a main body portion. In the present embodiment, the width direction of the wing portion and the width direction of the flap portion substantially coincide with each other, but they may not necessarily coincide with each other.

The absorbent article 1 has a topsheet 10, a backsheet 20, a main body absorbent body 30, and a flap absorbent body 35. The main body absorbent body 30 and the flap absorbent body 35 are disposed between the topsheet 10 and the backsheet 20. Therefore, the main body absorbent body 30 and the flap absorbent body are shown by broken lines in Fig. 1 and Fig. The main body absorbent body 30 is disposed at a central portion in the longitudinal direction L and the width direction W along the front-back direction of the absorbent article 1. [ The flap absorbent body 35 is disposed in the flap portion and is disposed in the vicinity of both end portions in the width direction of the absorbent article.

In the present embodiment, the main body absorbent body 30 and the flap absorbent body 35 are made of the same absorbent material and are also integrated. However, the main body absorbent body 30 and the flap absorbent body 35 may be constituted by different absorbent materials, or may not be integrated, but may be separately provided. The body absorbent body 30 and the flap absorbent body 35 may have different thicknesses.

The topsheet 10 is a sheet which permeates liquid such as body fluids. The topsheet 10 covers at least the surface of the main body absorbent body. The topsheet 10 has a body topsheet 11 disposed at least in the main body portion 2 and a flap topsheet 12 disposed in the flap portion 60. [ The main body top sheet is not particularly limited as long as it is a sheet-like material having a structure permeable to liquid such as a nonwoven fabric, a woven fabric, a perforated plastic sheet, or a mesh sheet. As the material of the woven fabric or the nonwoven fabric, any of natural fibers and chemical fibers can be used.

The flap top sheet 12 covers at least the flap portion 60. The flap top sheet 12 according to the present embodiment is arranged so as to cover the flap portion 60, the wing portion 43, and a portion of the main body portion (both ends in the width direction of the main body portion). The flap top sheet 12 may be a nonwoven fabric, a woven fabric, a perforated plastic sheet, a mesh sheet, or the like, and may be a structure that transmits liquid, and a structure that does not transmit liquid.

However, when the flap top sheet 12 is hydrophobic or water repellent, the menstrual blood can be suppressed on the inner side in the width direction than the flap top sheet. Since the flap top sheet 12 is broken by the flap embossing portion to be described later even when the menstrual blood flows on the flap top sheet, The menstrual blood can be drawn into the absorber.

The flap top sheet 12 according to the present embodiment is constituted by an air through nonwoven fabric. The air through nonwoven fabric is smooth and soft. By improving the texture of the flap portion when the flap portion is arranged along the body, the mounting feeling can be further improved.

The backsheet 20 has a length substantially equal to the length of the topsheet 10. The backsheet 20 may be formed of a breathable resin film such as a polyethylene sheet, a breathable film containing calcium carbonate or barium sulfate, a laminated nonwoven fabric mainly made of polypropylene or the like, a breathable resin film, a spunbond or a spun lace Bonded sheet or the like can be used. The backsheet 20 is preferably made of a material having flexibility so as not to cause an uncomfortable feeling when worn. The backsheet 20 is preferably liquid impermeable and moisture-permeable, and may be formed of a microporous sheet obtained by melt-kneading an inorganic filler with an olefin resin such as polyethylene or polypropylene.

The main body absorbent body 30 and the flap absorbent body 35 include hydrophilic fibers and pulp. The main body absorbent body 30 and the flap absorbent body 35 are formed of a material capable of absorbing body fluids such as menstrual blood. The main body absorbent body 30 and the flap absorbent body 35 may be formed by laminating a hydrophilic fiber or powder according to an airlaid method or may be an airlaid sheet formed by forming a hydrophilic fiber or powder into a sheet form by an airlaid method, (For example, a unit weight of 15 g / m < 2 >), and enclosing the pulp pulp with a tissue.

The main body absorbent body 30 and the flap absorbent body 35 according to the present embodiment are formed by wrapping a pulp obtained by laminating a sheet pulp or synthetic pulp on a basis weight of 100 g / m 2 to 300 g / m 2 with a protective paper (not shown) Consists of. Further, the main body absorbent body 30 and the flap absorbent body 35 may have substantially uniform thickness over the entire surface, or may have a non-uniform thickness. The protective paper is for keeping the shape of the pulp, and for example, a crepe paper or a tissue paper can be used.

The main body absorbent body 30 is provided so as to include the center of the excretion foot contact area at least with which the excretion of the wearer comes into contact. The center of the excretion port contact region coincides with the longitudinal direction and the center in the width direction of the central region where the excretion of the wearer contacts. For example, in the case of an absorbent article having a wing portion, the center in the longitudinal direction of the wing portion becomes the center in the longitudinal direction of the central region. In the absorbent article having no wing portion, the position having the shortest length dimension in the width direction of the absorbent body becomes the center in the longitudinal direction of the central region. Further, the excretion port contact area is included in a region in contact with the crotch part of the wearer, and is located between the legs of the wearer.

The flap absorbent body (35) is provided on the outer side in the width direction than the body absorbent body (30). The flap absorbent body 35 is located on the inner side in the width direction than the outer edge of the flap portion 60. The flap absorbent body 35 is positioned inside the outer edge embossed portion (described later) provided at the outer edge of the absorbent article.

In the absorbent article 1, the main body top sheet 11 or the flap top sheet 12 and the peripheral edge of the back sheet 20 are joined together and the main body absorbent body is sealed. At the outer edge of the absorbent article, an outer edge embossed portion 85 to which the topsheet 10 and the backsheet 20 are joined is formed. The topsheet 10 and the backsheet 20 are pressed in the thickness direction of the outer edge embossed portion 85. As a bonding method of the top- and backsheets 10 and 20, any one of heat-embossing, ultrasonic waves, hot-melt adhesives, or a combination of a plurality of them can be used.

In the backsheet 20, the surface contacting the undergarment is provided with a bonding portion coated with an adhesive in a plurality of regions (see Fig. 2). The adhesive portion is provided on the back side of the main body portion and includes a central adhesive portion 51 for fixing the absorbent article 1 to the crotch portion of the undergarment and a wrist portion 43 provided on the back side of the wing portion 43, And a flap adhering portion 53 provided on the back side of the flap portion 60 for fixing the flap portion in an extended state with respect to the back side of the undergarment.

In the state before use, the adhesive is in contact with a release sheet (not shown). The release sheet prevents the adhesive from deteriorating before use. Then, the release sheet is peeled off by the wearer during use.

In the absorbent article having no release sheet, the adhesive sheet may be prevented from deteriorating before use by a package sheet for individually packaging the absorbent article. When the adhesive and the package sheet are in contact with each other, it is preferable that the surface of the package sheet is treated so that the adhesive can be peeled off without lowering the adhesive force of the adhesive.

The absorbent article 1 is provided with a main body embossed portion 80 in which the topsheet 10 and the main body absorbent body 30 are compressed in the thickness direction and a flap embossed portion 70 Is formed. The main body embossed portion 80 and the flap embossed portion 70 are formed by pressing at least the topsheet 10 and the main body absorbent body in the thickness direction T or pressing at least the topsheet 10 and the flap absorbent body It may be formed by pressing in the direction T, and various configurations can be adopted. For example, it may be formed by press working or embossing, and the shape thereof may be a lattice network or honeycomb.

The flap portion 60 is formed with a plurality of constricted portions whose length in the width direction is shorter than the width direction length of the front and rear regions. The constricted portion has a first constricted portion 61 located on the front side and a second constricted portion 62 located on the rear side.

The flap portion 60 includes a first flap portion 63 located forward of the first constriction portion 61 and a second flap portion 63 located forward of the second constricted portion 62, And a third flap portion 65 positioned rearward of the second constriction portion 62. The second flap portion 64 has a second flap portion 65 located at the rear of the second constricted portion 62,

The first flap portion 63 is an area from the rear inner end portion 43RI located rearward of the inner end portion in the width direction of the wing portion 43 to the first constricted portion 61 and the rear inner end portion 43RI to the outside in the width direction. The first maximum width position (outer end) 63WM located at the outermost widthwise position in the first flap portion 63 is located outside the first constriction portion 61 in the width direction. The first maximum width position 63WM is located behind the center of the first flap portion 63 in the front-rear direction.

The second flap portion 64 is a region from the first constricted portion 61 to the second constricted portion 62 which is the rear end portion of the first flap portion 63 and extends from the first constricted portion 61 to the rear And extends outward in the width direction according to the facing. The second maximum width position (outer end) 64WM located at the outermost widthwise position in the second flap portion 64 is located outside the second constricted portion 62 in the width direction. The second maximum width position 64WM is located behind the center of the second flap portion 64 in the longitudinal direction.

The third flap portion 65 is a region from the second constricted portion which is the rear end portion of the second flap portion 64 to the rear side end portion of the flap portion and extends from the second constricted portion 62 in the width direction Respectively. The third maximum width position (outer end) 65WM located at the outermost widthwise position in the third flap portion 65 is located outside the second constricted portion 62 in the width direction. The third maximum width position 65WM is located behind the center of the third flap portion 65 in the longitudinal direction.

Next, the flap embossed portion will be described in detail. The flap embossing section includes a first flap embossing section 71 extending rearward from the vicinity of the rear inner end 43RI of the wing section 43 and a second flap embossing section 71 branched from the first flap embossing section 71, A second flap embossed portion 72 extending from the first flap embossed portion 71 and extending toward the second constricted portion 62; And a fourth flap emboss part 71 branched from the first flap emboss part 71 and extending in the vicinity of a third maximum width position 65WM located outside the width direction of the third flap part 65. [ (74). The flap embossed portion 70 is formed in a region where the flap absorber 35 is disposed.

According to the absorbent article thus constructed, since the flap absorbent body has the flap absorbent body, it is possible to absorb the body fluids and to suppress the fountain back and the lateral fountain. For example, in a sleeping posture, menstrual blood or the like may leak from the gap between the buttocks and the absorbent article. However, since the flap absorber 35 is provided in the flap portion 60, it is possible to suppress the spring back.

Further, since the flap absorber 35 is provided in the flap portion 60, the rigidity of the flap portion is increased, and the flap portion may be less likely to be deformed. However, the second flap embossed portion 72, the third flap embossed portion 73, and the fourth flap embossed portion 74 are configured to extend outward in the width direction from the inside in the width direction toward the rear side The flap embossed portion becomes a starting point of folding, and the flap portion is folded naturally, since the flap embossed portion follows the direction in which the force of the flap embossing is applied. Therefore, the flap portion 60 is easily fit to the body and the underwear easily. Therefore, wrinkles are not easily generated in the flap portion, and deformation without discomfort is possible, and a fresh feeling of mounting is obtained.

The flap embossed portion is constituted by a plurality of embossed constituent portions pressed in the thickness direction. Specifically, the second flap embossing portion 72, the third flap embossing portion 73, and the fourth flap embossing portion 74 are constituted by an aggregate of a plurality of embossed dot forming portions . The dot-shaped embossed constituent parts are arranged in line and are not continuous with each other. According to the aggregate of the plurality of dot-shaped embossed constituent parts, it is possible to suppress the excessively hardened flap part by the embossed constituent parts as compared with the embossed constituent parts continuing in line form. Therefore, the flap portion is easily deformed smoothly along the line of the body, so that the flap portion can be fitted to the body more.

The first flap embossing portion extends along the longitudinal direction and is provided to be connected from the rear side end of the wing portion 43 to the rear side end portion of the flap portion. Therefore, when body fluids are diffused from the center in the width direction of the absorbent article toward the widthwise outer side, body fluids are drawn in the first flap embossed portion to inhibit body fluids from diffusing outward in the width direction from the first flap embossed portion .

Further, a plurality of flap embossed portions are arranged overlapping in the width direction. Specifically, the first flap embossing portion overlaps the second flap embossing portion, the third flap embossing portion, and the fourth flap embossing portion in the width direction. The second flap embossing portion overlaps the first flap embossing portion and the third flap embossing portion in the width direction. The third flap embossed portion overlaps the first flap embossed portion, the second flap embossed portion, and the fourth flap embossed portion in the width direction.

When the body fluids flow from the center in the width direction of the absorbent article toward the outside in the width direction, the first flap embossed portion 72, the second flap embossed portion 72, the third flap embossed portion 72, The flap embossing portion 73 and the fourth flap embossing portion 74 can prevent the body fluids from reaching the outer edge of the absorbent article by drawing the body fluids in double or triple.

Since the first flap embossing portion 71 extends along the longitudinal direction from the vicinity of the rear side end portion of the wing portion 43, the first flap embossing portion 71 is provided in the vicinity of the wing portion from the outside in the width direction to the inside in the width direction When pressed, it becomes a starting point of deformation. Since a plurality of flap embossed portions are provided by branching from the first flap embossed portion 71, even when the deformation is largely deformed in the vicinity of the wing portion 43, deformation can be performed starting from a plurality of flap embossed portions, The entire flap portion can be flexibly deformed.

The first flap embossing portion 71 is spaced apart from the rear side end portion of the wing portion 43 as a rear side than the rear side end portion of the wing portion 43. However, the first flap embossing portion 71 is not limited to this configuration. The first flap embossing portion 71 may extend from the rear end of the wing portion 43 toward the rear.

The outer edge embossed portion 85 is provided on the outer edge of both ends in the width direction of the absorbent article. The outer edge embossed portion 85 is constituted by a plurality of embossed constituent portions pressed in the thickness direction. Specifically, the outer edge embossment section 85 is constituted by an aggregate of a plurality of dot-shaped embossment constituent parts. The dot-shaped embossed constituent parts are arranged in a line shape and are not continuous with each other.

The embossment forming portion of the dot shape constituting the outer edge embossing portion is configured to have a different shape or depth from the embossing forming portion of the dot embossing constituting the flap embossing portion. Specifically, the area of the embossed constituent portion constituting the flap embossed portion is larger than the area of the embossed constituent portion of the pointed type constituting the outer-edge embossed portion. Alternatively, the depth of the dot-shaped embossed constituent portion constituting the flap embossed portion is deeper than the depth of the dotted embossed constituent constituting the outer-edge embossed portion.

Since the flap embossed portion is disposed substantially inside the outer edge embossed portion so as to be substantially continuous, it is possible to prevent the body fluid from flowing to the outer edge of the absorbent article. In addition, the user can clearly recognize the second flap embossing portion 72, the third flap embossing portion 73, and the fourth flap embossing portion 74, It is possible to recognize that the additional portion exists inside the outer edge of the absorbent article, and it is possible to obtain a sense of security that it is difficult for the portion to flank.

Further, the embossed constituent part constituting the flap embossed part is larger than the embossed constituent part constituting the outer-edge embossed part, or is deeper in depth, and is more conspicuous. Therefore, the flap emboss part can be made relatively prominent. The user can easily recognize the flap embossed portion which is laterally inside the outer edge of the absorbent article and clogs the fountain, so that more relief can be obtained.

It is preferable that the shape of the embossed constituent part constituting the flap emboss part and the shape of the embossed constituent part constituting the outer edge emboss part are different. The emboss constituent parts are different in shape from each other not only in the shape of the outer shape such as the circular shape and the triangular shape but also in the shape having the same shape and different size. The shape of the embossed constituent part constituting the flap embossed part and the shape of the embossed constituent part constituting the outer edge embossed part are made different from each other so that the flap emboss part in which the body fluids can be introduced is present inside the outer edge of the absorbent article It can be recognized, and it is possible to obtain a sense of security that the fountain is not easily generated on the side.

The outer edge embossed portion and the flap embossed portion are disposed with an interval. For example, if the outer edge embossed portion and the flap embossed portion are continuous, the body fluid drawn by the flap embossed portion may be propagated to the outer edge embossed portion. However, since the outer edge embossed portion and the flap embossed portion are apart from each other, it is possible to prevent the body fluid drawn by the flap embossed portion from propagating to the outer edge embossed portion, and to suppress leakage of the body fluid.

Next, a part of the manufacturing method of the absorbent article 1 according to the first embodiment will be described. As for the method not described, an existing method can be used. In the method for manufacturing an absorbent article, as a first step, a surface sheet forming step is performed. Next, as the second step, the surface sheet bonding step is performed. Specifically, the main body top sheet 11 and the flap top sheet 12 are bonded by, for example, thermal welding.

As the third step, an absorber molding process is performed. Specifically, a pulp to be a material of an absorbent body is formed by a forming drum to form a main body absorbent body and a flap absorbent body. The order of the steps of manufacturing the topsheet in the first and second steps and the step of forming the absorbent body in the third step may be reversed.

In the fourth step, a bonding step is performed. Specifically, a joining step for joining the topsheet and the side sheet joined in the second step to the main body absorbent body and the flap absorbent molded in the third step is performed.

In the fifth step, a pressing process is performed. Specifically, the main body absorbent body and the topsheet 10 are compressed in the thickness direction to form the main body embossed portion 80, and the flap top sheet 12 and the flap absorbent body 35 are compressed in the thickness direction, Thereby forming a flap embossed portion 70. In the sixth step, the backsheet bonding step is performed. More specifically, the absorber, the topsheet, and the like, on which the embossed portion is formed, and the backsheet are bonded. After the above step, a step of forming the outer edge embossed portion 85 and a step of applying an adhesive agent are provided. By the above process, the absorbent article according to the present embodiment can be produced.

Next, the absorbent article 1A according to Modification Example 1 will be described. 5 is a plan view of a part of the absorbent article 1A according to Modification 1, viewed from the front surface side. The absorbent article shown in Fig. 5 has embossed emboss constituent parts 91 representing embossed shapes and embossed embossed embossed constituent parts 92 representing embossed emboss constituent parts constituting the embossed flap part.

The embossed embossed structure 91 is an embossed embossed embossed shape. In addition, the figure shape is a concept including polygons such as points, lines, circles, triangles, and squares. The pattern embossed constituent part 92 is an embossed part showing a pattern shape. Also, the shape of a pattern is a concept including various shapes and pictures such as a star pattern, a heart pattern, a leaf pattern, and a floral pattern.

By having the pattern emboss forming section 92, the aesthetic appearance can be increased. Further, the absorbent article 1A can be decorated adorably, and the depressed mood during the user's physiology can be alleviated. Further, the pattern embossed constituent unit 92 recognizes that there is an embossed portion that is easier to notice than the line-shaped embossed portion and allows the user to absorb the body fluid on the inner side than the outer-edge embossed portion 85 . Therefore, the user can obtain a sense of security for the fingers more sideways.

Further, the area of the embossed pattern embossing portion 92 is larger than the area of the embossed embossed pattern forming portion 91. Therefore, the pattern embossed constituent part 92 is more conspicuous than the embossed constituent part 91 and plays a role of an eye mark. For example, when the menstrual blood is diffused in the flap portion 60, the flap embossing portion introduces menstrual blood and blurs. At this time, since the menstrual blood is spread in the pattern emboss constituent section having a relatively large area, the pattern emboss constituent section in which the menstrual blood is diffused is recognized by the user, and it is easy to judge the replacement timing.

The embossed embossed constituent parts 91 are arranged on a predetermined line, and the embossed embossed constituent parts are arranged shifted from the line. In addition, the line includes not only a straight line but also a curved line. By arranging the embossment forming section 91 on a predetermined line, it is possible to densely arrange the embossment forming section 91 and to draw the body fluid from the embossment forming section 91, . In addition, by arranging the pattern embossed constituent parts 92 to be shifted from the line in which the embossed constituent elements 91 are arranged, the pattern embossed constituent parts 92 can be conspicuous, While securing it, the aesthetics can be increased.

The width dimension W92 perpendicular to the predetermined line of the pattern embossed constituent element 92 is larger than the predetermined line width W91. Since the width dimension orthogonal to the predetermined line of the pattern embossed constituent part 92 is larger than the width of the line in which the embossed constituent element 91 is disposed, the pattern embossed constituent part 92 can be conspicuous There, it can increase beauty. Since the area of the pattern embossed constituent part 92 is large, even if the body fluid infiltrates the whole of the embossed figure embossing section 91, the body embedding structure 92 does not infiltrate the entire body of the embossed emboss structure 92 And the pattern emboss formation section 92 can grasp the replacement timing.

In addition, if the embossed emboss structure 92 is shifted from the emboss embossed structure 91, the embossed emboss structure 91 can prevent deformation of the embossed structure 91 . Specifically, when the flap portion is deformed from the vicinity of the joint portion of the wing portion as a starting point, the embossed portion of the figure embodied in a constant line shape becomes a starting point of deformation. At this time, deformation of the flap portion is apt to stop at a portion where the pattern emboss structure portion deviated from the line of the embossed figure forming portion is disposed, and excessive deformation of the flap portion can be suppressed. If the width of the embossed pattern embossing portion 92 is larger than the width of the embossed embossed pattern portion 91, the embossed embossed pattern forming portion 92 is arranged in a line The effect of suppressing deformation of the flap portion can be obtained.

It is also preferable that the pattern embossed constituent part is arranged behind the line of the embossed constituent part of the figure emblem. In the case where the pattern embossed constituent part is arranged behind the line of the embossed constituent part of the graphic form, it is possible to suppress the deformation of the flap part toward the rear when the flap part is deformed from the wing part side located at the front side.

A plurality of embossed embossed constituent parts 91 are arranged adjacent to each other, and a pattern embossed constituent part 92 is disposed between embossed embossed constituent parts 91. The interval P1 between the pattern embossed constituent parts 92 and 91 is larger than the interval P2 between the figure embossed constituent parts 91. [ The pattern embossed constituent section 92 can be conspicuous by making the interval between the pattern embossed constituent section 92 and the embossed constituent element section 91 larger than the interval between the embossed constituent elements 91 , Aesthetics can be increased.

In addition, the emboss constituent part constituting the outer edge emboss part may include a pattern emboss constituent part 92. However, in order to prevent the outer edge of the absorbent article from being opened, it is preferable that the outer edge embossed portion is provided with a gap or a lattice-shaped embossed portion without gaps.

The flap embossing portion according to Modification Example 1 is provided with two rows spaced apart in the longitudinal direction. The rear flap embossing portion is formed so as to extend in the width direction from the inside in the width direction toward the rear side in the region ahead of the third maximum width position 65WM as the maximum swelling portion located at the outermost widthwise position in the flap portion And extends rearward from the outside in the width direction toward the inside in the width direction in a region behind the third maximum width position 65WM located at the outermost widthwise position in the flap portion.
