Description

  The present invention relates to an absorbent article. More specifically, the present invention relates to an absorbent article that can be easily used in combination with ordinary cloth underwear.

  Light incontinence products include cloth light incontinence pants with absorbent cotton in the crotch of cloth pants, and products such as cloth pants with a holder function designed for easy use of absorbent articles (hereinafter referred to as “ Also called “holder pants”. Moreover, as a disposable product, a disposable pant that resembles a pants made of cloth on the exterior using a special nonwoven fabric rich in elasticity as an exterior sheet is known (see, for example, Patent Documents 1 and 2).

Japanese Patent Application No. 2005-294420 Japanese Patent Application No. 2005-238272

  Compared with such conventional light incontinence products, fabric products are superior in terms of touch and sweat absorption. The light incontinence pants made of cloth are suitable when the amount of absorption is a small amount of about several tens of cc, but there are problems that it takes time to dry after washing, and the cotton is easily yellowed because it is difficult to dry.

  Since the holder pants described above can be used in combination with a conventional absorbent article, for example, a urine pad, it can also be used when the amount of urine is large. The holder pants have a higher press-fit feeling than ordinary underwear for the purpose of supporting absorbent articles and may be difficult to wear. Since some of these cloth pants are prepared, washed, and reused, there is a problem that it is expensive at first.

  On the other hand, disposable pants can be thrown away after use, so there is no hassle of washing. However, the disposable pants have problems that sweat absorption, breathability, and touch are inferior to cloth pants. Furthermore, since disposable pants are different from normal pants in appearance, when they are seen by others, they may be informed that they are using disposable pants, and there is a sense of resistance to using disposable pants. May increase.

  As described above, it has been difficult to find a worn product that can be used smoothly both psychologically and functionally when a healthy person takes measures against light incontinence.

  In addition, by using the light incontinence pad attached to the underwear, it is possible to perform light incontinence care while using the conventional underwear as it is. Since such light incontinence care uses conventional underwear, the feeling of wearing the portion where the light incontinence pad does not touch the skin remains in a state where the underwear is worn. Therefore, comfort is maintained to some extent. Such a light incontinence pad is provided with an adhesive stopper tape or the like on the surface to be fixed to the underwear. And this slip prevention tape is stuck on underwear, and a light incontinence pad and underwear are temporarily fixed, and the slippage during wearing is prevented. Similar to the technique used in sanitary napkins, a light incontinence pad having a wing in which both sides of the light incontinence pad are extended outward on the crotch side of the underwear has been proposed. Such a wing is folded and attached to the outer surface of the underwear to fix the light incontinence pad to the underwear. These underwear fixing techniques can prevent misalignment of the incontinence pad and kinking, but if there is a gap between the underwear and the wearer, for example, underwear such as men's briefs When used in combination, there is also a problem that when urination occurs, urine flows in an unexpected direction through the user's body, causing urine leakage. The light incontinence pads described above are difficult to use in combination with trunks. Therefore, when using a light incontinence pad, the underwear to be used together is selected.

  The present invention has been made in view of the problems of the prior art as described above. That is, this invention provides the absorbent article which is easy to use together with the normal cloth underwear.

  According to the present invention, the following absorbent articles are provided.

[1] A liquid-permeable sheet and a liquid-impermeable sheet are laminated in a state where an absorbent body is sandwiched, and an absorbent main body that covers from the front part of the wearer to the crotch, an annular waistband, and the absorbent A pair of auxiliary bands that hold the main body in close contact with the wearer, and elastic elastic bodies are disposed on both side edges of the absorber, and the waistband includes a part of the waistband, the absorbent main body of has been secured to one end of the length direction and the pair of the auxiliary band, one end of each of said auxiliary band is detachably attached to the other end in the longitudinal direction of the absorbent body Or while being fixed so that attachment or detachment is not possible, the other end of the auxiliary band is fixed to the waistband.

[2] It is a tapered shape in which the width of at least the tip portion on the other end side opposite to the one end side where the absorbent main body is fixed to the waistband gradually decreases toward the other end side. The absorbent article according to [1], wherein at least the other end side of the absorbent main body is formed in a concave shape with a surface in contact with a wearer as an inner side surface. .

  The absorptive article of the present invention has the effect that it is easy to use together with normal cloth underwear. That is, the absorbent article of the present invention includes an absorbent main body, an annular waistband, and an auxiliary band that holds the absorbent main body in close contact with the wearer.

[Embodiment 1]
Hereinafter, Embodiment 1 of the absorptive article of the present invention is described using a drawing. As shown in FIGS. 1 to 6, the absorbent article 100 of Embodiment 1 includes an absorbent main body 2, an annular waistband 4, an auxiliary band 3 that holds the absorbent main body 2 in close contact with the wearer 20, It is the absorbent article 100 provided with. The absorbent main body 2 is laminated with a liquid-permeable sheet (for example, a top sheet 10) and a liquid-impermeable sheet (back sheet 11) sandwiching the absorber 9, and from the wearer's front to the crotch It covers. Further, the waistband 4 is obtained by fixing a part 4 e of the waistband 4 to the one end 2 a side in the length direction of the absorbent main body 2. The auxiliary band 3 has one end 3b of the auxiliary band 3 fixed to the other end 2b side of the absorbent main body 2 in a removable or non-detachable manner, and the other end 3a of the auxiliary band 3. Is fixed to the waistband 4.

  As shown in FIGS. 1 to 3, the wearer 20 wears the absorbent article 100 by passing his / her leg through at least a region (leg opening 18) defined by the absorbent main body 2 and the auxiliary band 3. In the absorbent article 100 shown in FIGS. 1 to 3, leg opening 18 is formed in a region defined by the absorbent main body 2, the auxiliary band 3, and the waistband 4. By setting it as such a structure, the absorptive main body 2 can be made to contact | abut to the wearer's 20 body favorably and can be worn. Therefore, according to the absorbent article 100 of Embodiment 1, light incontinence care can be performed with the absorbent article 100 alone, regardless of the type of underwear (not shown) further worn on the absorbent article 100. Further, since the waistband 4 wraps around the wearer around the waist on the crotch side from the navel, it is easy to hide and wear in a general cloth underwear. As described above, the types of underwear to be worn are It is not limited and it becomes difficult for others to know that the absorbent article 100 is used. For this reason, an absorptive article can be used smoothly psychologically and functionally. Thus, the absorbent article 100 of Embodiment 1 is easy to use together with normal cloth underwear.

  Here, FIG. 1 is a front view schematically showing Embodiment 1 of the absorbent article of the present invention. FIG. 2: is the perspective view seen from diagonally forward which shows Embodiment 1 of the absorbent article of this invention typically. Fig. 3 is a perspective view schematically showing the first embodiment of the absorbent article of the present invention as viewed obliquely from the rear. FIG. 4 is a plan view schematically showing a state in which the first embodiment of the absorbent article of the present invention is developed. FIG. 5 is a cross-sectional view schematically showing the Q-Q ′ cross section of FIG. 4. FIG. 6 is a plan view schematically showing a state in which one end of the auxiliary band is fixed to the absorbent main body of the absorbent article shown in FIG. 4. Moreover, in this specification, "the length direction of the absorptive main body 2" means the absorptive main body 2 and the auxiliary band 3 from one end 2a of the absorptive main body 2 to which the absorptive main body 2 and the waistband 4 are fixed. Means the direction toward the other end 2b of the absorbent main body 2 to be fixed. Further, “the one end 2a side in the length direction of the absorbent main body 2” may be referred to as “the front end portion of the absorbent main body 2”, and “the other end 2b side in the length direction of the absorbent main body 2”. This is sometimes referred to as “the rear end of the absorbent main body 2”. This is because the “front end of the absorbent main body 2” is mainly located on the front body side of the wearer 20, and the “rear end of the absorbent main body 2” extends from the crotch part of the wearer 20 to the lower body. By mainly located on the side.

  When the wearer 20 wears the absorbent article 100, the wearer 20 is worn so that the site where the absorbent main body 2 is fixed to the waistband 4 is positioned on the front body side of the wearer 20. And as above-mentioned, a leg is passed through the opening part (leg opening part 18) formed between the absorptive main body 2 and the auxiliary | assistant band 3, and the absorbent article 100 is worn. In addition, when the absorptive main body 2 and the auxiliary | assistant band 3 are comprised so that attachment or detachment is possible, it attaches and fixes one end 3b of the auxiliary | assistant band 3 to the other end 2b side of the absorptive main body 2 before wearing. The absorbent article 100 may be worn after the leg opening 18 is formed. With such a structure, it is easy to use even for a wearer who has difficulty in movement of limbs, body, etc., and who is difficult to attach an auxiliary band on the crotch side to attach to the absorbent main body.

  Further, for example, without attaching one end 3 b of the auxiliary band 3 to the other end 2 b side of the absorbent main body 2, first, after passing the body of the wearer 20 through the waistband 4, The end 3b may be attached to the other end 2b side of the absorbent main body 2 so that the crotch portion is hidden from the buttocks or outer thigh side of the wearer 20 and worn. With this structure, the user can adjust the length of the auxiliary band and fix it to the dimensions just around the wearer's leg, so the absorbent body can fit the body and prevent leakage can do.

  The absorbent main body 2 preferably has a length that covers at least the crotch part of the wearer 20 from the position where the waistband 4 is worn when the absorbent article 100 is worn. In order to make it easy to wear the absorbent article of the present invention under the underwear, the waistband is fixed on the crotch side, and the size of the absorbent body is also important. The length may be the same as the length from the wearing position (the lower fixing portion of the waistband) to the inseam of the wearer.

  The fixing position of the other end 3a of the auxiliary band 3 and the waistband 4 is preferably on the lower body side of the wearer 20 at the time of wearing. As a result, the leg opening 18 that fits well near the root of the wearer's leg is formed by the region defined by the absorbent main body 2, the auxiliary band 3, and the waistband 4.

  Hereinafter, the absorbent article of Embodiment 1 is demonstrated in detail for every component.

(1-1. Girth band)
As shown in FIGS. 1 to 6, the annular waistband 4 in the absorbent article 100 of the first embodiment is an annular belt body that is attached to the waistline of the wearer 20. The waistband 4 is preferably made of a stretchable material. Examples of the stretchable material include a member in which an elastic stretch body is sandwiched between nonwoven fabrics and a stretchable nonwoven fabric. The stretchable nonwoven fabric is a functional nonwoven fabric that is stretchable by itself, and includes, for example, a nonwoven fabric using elastic yarn made of an elastomer of thermoplastic synthetic resin or urethane. Moreover, as such a stretchable nonwoven fabric, for example, a sheet-like base material having a fiber layer formed by a melt blow method may have a large number of wrinkled wrinkles formed by creping.

  The stretchable material used for the annular waistband 4 can be stretched in the length direction (circumferential direction of the annular waistband 4) to 1.2 times the length before stretching. Preferably there is. Furthermore, it is preferable that the stretchable material can be stretched to a length of 3 times, and the subsequent recovery is 1.5 times or more of the original length. If it is a raw material which has such a stretch elasticity, it can be easily widened at the time of wearing, and it can prevent effectively that it loosens and falls off during wearing.

  The waistband 4 should just be comprised cyclically | annularly in the state which worn the absorbent article 100. FIG. That is, the “annular waistband 4” is a waistband that is in a ring shape, and is of course assembled in a ring shape (in other words, manufactured in advance so as to be in a ring shape). Also included is a configuration in which the wearer 20 is configured to assemble in an annular shape before or during wearing. Specifically, the waistband 4 can be formed into an annular shape in advance by joining one end 4a and the other end 4b of the belt-like waistband 4 as shown in FIG. 3). As a joining means for joining one end 4a and the other end 4b of the waistband 4, a suitable joining means can be appropriately selected from ultrasonic sealing, heat sealing, hot melt adhesive, and the like. Further, a hook material (not shown) and a loop material (not shown) of a mechanical fastener may be arranged on one end 4a and the other end 4b of the waistband 4. In the waistband 4 configured in this way, when the wearer or caregiver wears the absorbent article 100, the hook material and the loop material are engaged with each other, and one end 4a of the waistband 4 is engaged. And the other end 4b are joined. Here, the “hook material” is a convex member of a mechanical fastener (also referred to as a planar fastener), and can be fixed by mechanical coupling with a loop material that is a concave material. On the other hand, as the “loop”, those having loop-like fibers arranged on the surface are often used. Further, fixing means other than the above-described mechanical fastener may be disposed on one end 4 a and the other end 4 b of the waistband 4. For example, fixing means such as clasps (hooks), buttons, etc. used for adhesives, clothes, etc. are arranged, and the wearer or caregiver assembles the waistband 4 in an annular shape (that is, with one end 4a and The other end 4b may be fixed).

  As shown in FIG. 5, when the waistband 4 is made of the stretchable nonwoven fabric 7, the other end of the auxiliary band 3 is placed on the inner surface 7 b (that is, the skin contact surface side) of the stretchable nonwoven fabric 7. It is preferable to fix 3a. Although fixing the other end 3a of the auxiliary band 3 to the outer surface 7a of the stretchable nonwoven fabric 7 is not prevented, the other end 3a of the auxiliary band 3 is fixed to the inner surface 7b of the stretchable nonwoven fabric 7. Thus, the appearance of the absorbent article 100 is improved. There is no restriction | limiting in particular about the fixing method of the trunk band 4 and the auxiliary | assistant band 3, It is preferable to adhere and fix using well-known adhesives, such as a hot-melt-adhesive.

  Here, another example of the structure of the stretchable material constituting the waistband 4 and the fixing method with the other end 3a of the auxiliary band 3 will be described with reference to FIGS. 7 to 11 are cross-sectional views schematically showing another example and still another example of the fixing portion between the waistband and the auxiliary band. 7 to 11 show a cross section at the same place as the cross section shown in FIG. 5 (Q-Q ′ cross section in FIG. 4). In FIG. 7, the stretchable nonwoven fabric 7 constituting the waistband 4 has a single outer surface 7a, but has a double inner surface. This inner surface side is composed of an inner surface 7b and an intermediate surface 7c. In FIG. 7, the other end 3a of the auxiliary band 3 is fixed to the inner surface 7b of the stretchable nonwoven fabric 7.

  In FIG. 8, the stretchable nonwoven fabric 7 constituting the waistband 4 has a single inner surface 7 b but a double outer surface side. The outer surface side includes an intermediate surface 7c and an outer surface 7a, and the other end 3a of the auxiliary band 3 is sandwiched and fixed between the inner surface 7b and the intermediate surface 7c of the stretchable nonwoven fabric 7. In this way, the other end 3a of the auxiliary band 3 is sandwiched between the elastic nonwoven fabrics 7 and bonded and fixed, so that the level difference at the joint portion of the auxiliary band 3 is relaxed by the elastic nonwoven fabric 7, and thus the absorbent article. The feeling of wearing 100 is improved.

  9 to 11 show an example in which the waistband 4 is configured by a member in which the elastic stretchable body 16 is sandwiched by the nonwoven fabric 17. That is, in FIG. 9, the waistband 4 is formed of a stretchable material in which a stretchable elastic body 16 is fixed and sandwiched between nonwoven fabrics 17 bent in a U shape or the like. The stretchable elastic body 16 is preferably bonded to the nonwoven fabric 17 using an adhesive such as a hot melt adhesive. In FIG. 9, the other end 3 a of the auxiliary band 3 is fixed to the inner surface 17 b of the nonwoven fabric 17 constituting the waistband 4. As the elastic elastic body 16, urethane thread rubber, natural rubber, synthetic rubber, urethane foam, urethane film, elastomer, and the like can be used.

  In FIG. 10, the outer surface 17a of the nonwoven fabric 17 is single, but the inner surface side is double, and this inner surface side is composed of an inner surface 17b and an intermediate surface 17c, and the elastic surface is formed by the intermediate surface 17c and the outer surface 17a. 16 is sandwiched. In FIG. 10, the other end 3 a of the auxiliary band 3 is fixed to the inner surface 17 b of the nonwoven fabric 17.

  In FIG. 11, the non-woven fabric 17 constituting the waistband 4 has a single inner surface 17b, but a double outer surface. The outer surface side is composed of an intermediate surface 17c and an outer surface 17a, and the stretchable elastic body 16 is sandwiched between the intermediate surface 17c and the outer surface 17a that are doubled. In FIG. 11, the other end 3 a of the auxiliary band 3 is sandwiched and fixed between the inner surface 17 b and the intermediate surface 17 c of the nonwoven fabric 17. Thus, the other end 3a of the auxiliary band 3 is sandwiched between the nonwoven fabrics 17 and bonded and fixed, so that the level difference at the joined portion of the auxiliary band 3 is alleviated by the nonwoven fabrics 17, and thus the wearing feeling of the absorbent article 100 Will improve.

  There is no restriction | limiting in particular about the length of the circumferential direction of the cyclic | annular trunk periphery band 4, According to the size of the wearer's 20 trunk periphery, it can set suitably. In the case where a hook material and a loop material of a mechanical fastener are disposed on one end 4a and the other end 4b of the waistband 4, the loop material is disposed longer in the circumferential direction of the waistline, and the hook The engagement range with the material may be provided wider. By comprising in this way, the size of the trunk periphery of the annular trunk band 4 can be adjusted by the engagement position of a hook material.

  The width t1 (see FIG. 4) orthogonal to the circumferential direction of the annular waistband 4 is not particularly limited. However, if the width t1 of the waistband 4 is too wide, when the underwear is worn on the absorbent article 100, the absorbent article 100 (particularly, the waistband 4) may be difficult to hide. For this reason, the width t1 of the waistband 4 is preferably 5 to 150 mm, more preferably 10 to 100 mm, and particularly preferably 20 to 80 mm. If the width t1 of the girth band 4 is less than 5 mm, the strength of the girth band 4 tends to be weak, and it may bite into the girth and deteriorate the feeling of wear. On the other hand, when the width t1 of the waistband 4 is more than 150 mm, the waistband 4 may be easily exposed when the underwear is worn.

  In addition, the waistband 4 of the absorbent article 100 passes the absorbent article 100 through the leg of the wearer 20 in a region (leg opening 18) defined by the absorbent main body 2, the auxiliary band 3, and the waistband 4. When worn, it is preferably configured as follows. That is, the waistband 4 divides the virtual line segment connecting the umbilicus of the wearer 20 and the lowest point of the pubic bone into 10 equal parts, and is located at the second to seventh positions from the bottom of the virtual line segment divided into 10 equal parts. It is preferable that it is comprised so that it may be arrange | positioned. By comprising in this way, when the underwear is worn on the absorbent article 100, the waistband 4 is hardly exposed from the underwear. Therefore, the waistband 4 has an appropriate tightening force for the wearer 100 at the above-mentioned “position from the second minute to the seventh minute from the bottom where the imaginary line segment connecting the navel and the lowest point of the pubic bone is equally divided into 10 parts”. It is preferable that the absorbent article 100 can be held by expressing the above.

(1-2. Absorbent body)
The absorbent main body 2 is formed by laminating a liquid permeable sheet and a liquid impermeable sheet with the absorbent body 9 interposed therebetween. Here, FIG. 12 is an exploded plan view of the absorbent article shown in FIG. FIG. 13 is a cross-sectional view schematically showing the XX ′ cross section of FIG. As shown in FIGS. 1 to 4, 6, 12, and 13, the absorbent main body 2 used for the absorbent article 100 of Embodiment 1 includes a top sheet 10 as a liquid-permeable sheet, an absorbent body 9, and It has a back sheet 11 as a liquid-impermeable sheet.

  The absorber 9 is made of an absorbent material in order to absorb and hold the urine of the wearer 20. As an absorptive material, a pulp, a synthetic fiber, a water absorbing polymer, a water absorbing fiber, etc. are employable, for example. Further, the absorbent body 9 is wrapped with absorbent body holding sheets 8a and 8b made of tissue or hydrophilic nonwoven fabric so that the water absorbent polymer does not jump out of the absorbent body 9 or the absorbent body 9 loses its shape. Is preferred. Further, the absorbent body 9 is sandwiched between the top sheet 10 and the back sheet 11 and is sealed between the top sheet 10 and the back sheet 11 by sealing the peripheral portions of both sheets. preferable.

  The top sheet 10 is a liquid-permeable sheet disposed so as to cover the skin contact surface side of the absorbent body 9. The top sheet 10 allows a liquid such as urine to penetrate into the absorber 9. As the liquid permeable material constituting the top sheet 10, for example, a woven fabric, a non-woven fabric, or a porous film can be employed. In particular, it is preferable to use a non-woven fabric made of a thermoplastic resin such as polypropylene, polyethylene, polyester, or nylon and subjected to a hydrophilic treatment.

  The back sheet 11 is a liquid-impermeable sheet disposed so as to cover the absorber 9 from the skin non-contact surface side. The back sheet 11 prevents the liquid held by the absorber 9 from leaking out of the absorbent main body 2. As the liquid-impermeable material constituting the back sheet 11, for example, a liquid-impermeable film made of a resin such as polyethylene can be employed. A microporous polyethylene film may be used.

Stretchable elastic bodies 12 are disposed on both side edges of the absorbent body 9 (side edge portions 2d of the absorbent main body 2). By comprising in this way, the side edge part 2d of the absorptive main body 2 becomes firm, and the absorptive main body 2 becomes easy to stick to the wearer 20. Furthermore, since it becomes difficult to make a gap between the wearer 20 and the absorbent main body 2, it is possible to effectively prevent the urine excreted by the wearer 20 from leaking out from the peripheral edge of the absorbent main body 2. The stretchable elastic body 12 is preferably arranged in an extended state along both side edges of the absorbent body 9 and is fixed between the top sheet 10 and the back sheet 11. As the elastic elastic body 12, urethane thread rubber, natural rubber, synthetic rubber, urethane foam, urethane film, elastomer, and the like can be used.

  A cover sheet 13 (see FIG. 13) may be disposed outside the back sheet 11. As the cover sheet 13, a liquid-impermeable nonwoven fabric can be used. By disposing such a cover sheet 13, the back sheet 11 can be reinforced and the feel of the absorbent article 100 can be improved. Further, the cover sheet 13 may be configured such that the outer peripheral portion 13 a of the cover sheet 13 is folded back to the skin contact surface side of the absorbent main body 2 to cover both ends of the top sheet 10. If such a structure is taken, it is possible to effectively prevent the lateral leakage of urine diffused through the top sheet 10.

  The absorbent main body 2 has a width enough to absorb excreted urine on the wearer 20's front body side, while the other end 2b side of the absorbent main body 2 is on the crotch portion of the wearer 20. It is preferable that the shape fits well into the wearer's crotch. For example, the width of at least the tip portion on the other end 2b side opposite to the one end 2a side on which the absorbent main body 9 is fixed to the waistband 4 is tapered, gradually decreasing toward the other end 2b side. It is preferable. Furthermore, it is also a preferable aspect that the absorbent main body 2 is formed in a concave shape in which at least the other end 2b side of the absorbent main body 2 has a surface in contact with the wearer 20 as an inner surface. By comprising in this way, when the male wearer 20 uses the absorbent article 100, the whole male genital can be encapsulated by the concave absorbent main body 2.

  As shown in FIG. 12, for example, the absorbent body 9 on the other end side of the absorbent main body 2 in the manufacturing process has a shape in which the central portion is notched, and the sides of the divided portions 2 </ b> C of the absorbent main body 2. Or it is preferable to form the edge part of the other end of the absorptive main body 2 by joining a surface in the shape of a palm or lamination. At this time, the amount of the notch on the skin contact surface side of the absorbent body 9 is increased, and at least the other end side of the absorbent main body 2 is further formed in a concave shape with the surface in contact with the wearer as the inner surface. preferable. By adopting such a structure, the absorbent main body 2 becomes a concave (bowl-shaped) three-dimensional shape along the line of the wearer's body at the crotch portion, and the gap between the wearer's body and the absorbent main body 2 Can be reduced. In FIG. 12, the cutout portion is formed in the central portion on the other end side of the absorber 9. For example, a plurality of cutout portions are formed on the other end side of the absorber 9, You may form in the concave type which used the skin contact surface as the inner surface by joining a notch part sequentially.

  Moreover, although illustration is abbreviate | omitted, what was shape | molded by the concave shape can also be used as a liquid-impermeable sheet | seat of an absorptive main body. For example, as a liquid-impermeable sheet, a foam molded body formed into a concave mold is used, and an absorbent body and a liquid-permeable sheet (that is, a top sheet) are disposed on the inner surface of the foam molded body to absorb the liquid. A sex body may be produced. By adopting such a structure, a concave absorbent main body having the skin contact surface as an inner surface can be obtained very simply.

  Although not shown in the drawings, the absorbent main body is made of a laminate of flat sheets, and the skin corresponding to the crotch part of the wearer is bonded to each other to fasten the crotch part of the absorbent main body. You may shape | mold so that it may become a concave type which used the contact surface as the inner surface. Furthermore, an absorptive main body consists of a laminated body of a planar sheet | seat, and it may approach a sheet | seat and may make the width | variety of a crotch part thin. By spreading the above-described tack, the absorbent main body has a concave shape with the skin contact surface as the inner surface. More preferably, the absorbent main body is formed (for example, molded) into a three-dimensional shape along the line of the wearer's body.

(1-3. Auxiliary band)
As shown in FIGS. 1 to 6, the auxiliary band 3 is for closely holding the absorbent main body 2 on the wearer 20. In particular, the auxiliary band 3 is an important member for forming the leg-hole opening 18 in the absorbent article 100. That is, the auxiliary band 3 is connected to the rear end portion (the end portion on the other end 2b side) of the absorbent main body 2 to form the leg opening 18 and the rear end portion ( The other end 2b side end) is lifted to the waist side of the wearer 20 so as not to create a gap.

  The auxiliary band 3 has one end 3 b fixed to the other end 2 b in the length direction of the absorbent main body 2 detachably or non-detachably, and the other end 3 a fixed to the waistband 4. It is a belt. The auxiliary band 3 is preferably made of a stretchable material. Examples of the stretchable material include a member in which an elastic stretch body is sandwiched between nonwoven fabrics and a stretchable nonwoven fabric. As the stretchable nonwoven fabric, a known stretchable nonwoven fabric using an elastic yarn made of an elastomer of thermoplastic synthetic resin, urethane, or the like can be used. In addition, as the stretchable nonwoven fabric, it is also possible to use a sheet-like base material having a fiber layer formed by a melt blow method, in which a large number of wavy wrinkles are formed by creping.

  The stretchable material used for the auxiliary band 3 can be stretched to 1.2 times the length before stretching in the direction from one end 3b to the other end 3a. Is preferred. Furthermore, it is preferable that the stretchable material can be stretched to a length of 3 times, and the subsequent recovery is 1.5 times or more of the original length. If it is a raw material which has such a stretch elasticity, it can be easily widened at the time of wearing, and it can prevent effectively that it loosens and falls off during wearing.

  As for the auxiliary band 3, one end 3b of the auxiliary band 3 may be fixed to the other end 2b side in the length direction of the absorbent main body 2 in a non-detachable manner in advance or may be fixed in a removable manner. . The above-described “removably fixed” means that one end 3 b of the auxiliary band 3 is configured to be removable with respect to the other end 2 b side in the length direction of the absorbent main body 2. To do. Therefore, in the absorbent article 100 as a product, one end 3 b of the auxiliary band 3 configured to be detachable may not be fixed to the other end 2 b side in the length direction of the absorbent main body 2. For example, a hook material of a mechanical fastener may be disposed on one end 3b of the auxiliary band 3, and the outer surface of the absorbent main body 2 may be a material that can be engaged with the hook material. In this case, since the wearer can adjust the engagement position of the hook material according to the circumference of his / her leg, the wearability of the absorbent article 100 is improved. For this reason, the leakage from the absorbent article 100 can be effectively suppressed.

  The width t2 (see FIG. 4) of the auxiliary band 3 is not particularly limited. However, if the width t2 of the waistband 4 is too wide, the wearing feeling of the absorbent article 100 is lowered, or when the underwear is worn on the absorbent article 100, the auxiliary band 3 protrudes from under the underwear. Sometimes. For this reason, the width t2 of the auxiliary band 3 is preferably 5 to 100 mm, more preferably 10 to 50 mm, and particularly preferably 15 to 35 mm. If the width t2 of the auxiliary band 3 is less than 5 mm, the strength of the auxiliary band 3 is likely to be weak, and it may bite into the body, resulting in poor wearing feeling. If the width of the auxiliary band 3 exceeds 100 mm, it may protrude from the underwear, or the auxiliary band 3 may be folded or twisted in the crotch, which may significantly impair the wearing feeling.

  Further, as shown in FIG. 14, a tape portion 27 can be fixed to one end 3 b of each of the pair of auxiliary bands 3, and a hook material can be disposed on the tape portion 27. Here, FIG. 14 is a partially enlarged plan view schematically showing an example in which a tape portion is disposed at one end of the auxiliary band. In order to make it easy to hold the tape part 27 on the joining tab 27 a formed by the tape part 27, a gripping tab 26 may be further provided. By providing such a tape portion 27, it is not necessary to fix the auxiliary bands 3 to the absorbent main body 2 one by one, and the lengths on the left and right sides can be easily adjusted.
