Description

The present invention relates to an absorbent article having an absorbent body. In particular, the present invention relates to an absorbent article in which the rear portion of the absorbent body can be pulled forward when discarded.

In the following description, disposable diapers are used as an example of an absorbent article, but this absorbent article is not limited to disposable diapers and also includes absorbent articles other than disposable diapers, such as sanitary napkins.

When an absorbent body absorbs a large amount of body fluids such as urine, it rises toward the inside, and opens outward in the width direction compared to before it absorbed the body fluids. This means that when disposing of the absorbent article, the worker's hands are more likely to come into contact with the body fluids and become soiled.

Inventions related to the present invention are disclosed in the following Patent Documents 1 to 4.
The absorbent article for pets disclosed in Patent Document 1 has an excrement disposal sheet fixed to an absorbent main body, and a string is provided on the peripheral edge of the excrement disposal sheet. When the string is pulled during excrement disposal, the fixation between the absorbent main body and the excrement disposal sheet is released, and the separated excrement disposal sheet becomes bag-shaped.

However, the pet absorbent article disclosed in Patent Document 1 had the problem that it had to be provided with an excrement disposal sheet, which is not present in ordinary absorbent articles.

The absorbent article disclosed in Patent Document 2 has insertion holes extending along the length direction formed on both sides in the width direction, and a long member is inserted inside the insertion hole. An opening is formed on the front end side of the insertion hole, and a fixing part is formed on the rear end side. The rear end of the long member is fixed to the fixing part, and the front side of the long member is pulled out from the opening. When the front part of the long member inserted into the insertion hole is pulled by hand, the absorbent article is rolled up with the top sheet on the inside and the back sheet on the outside, so that the hands do not come into contact with the absorbent body and it can be handled hygienically.

However, in the absorbent article disclosed in Patent Document 2, the top sheet, absorbent body, and back sheet are rolled up as a single unit, so when rolling up the absorbent body that has absorbed bodily fluids and become heavy, the rolling up process may be time-consuming or may not go smoothly. In particular, in the case of the sanitary napkin disclosed in Patent Document 2, this may still be an acceptable problem, but it is difficult to roll up an absorbent body that has absorbed a large amount of urine and become heavy, as in the case of a disposable diaper.

In the absorbent article disclosed in Patent Document 3, a pair of tubular parts extending in the length direction are formed on both sides in the width direction of the absorbent body, and a pair of string-like members extending in the length direction are inserted inside the tubular parts. Both ends of the string-like members are fixed to both ends in the length direction of the tubular part, respectively, and the parts other than the both ends can be freely drawn out to the outside of the tubular part through outlet holes provided on the circumferential surface of the tubular part. The entire absorbent article can be folded by drawing the string-like members out to the outside of the tubular part through the outlet holes. Therefore, it can be folded without touching the parts of the liquid-permeable sheet on which body fluids are attached.

However, the absorbent article disclosed in Patent Document 3 also folds the liquid-permeable sheet, absorbent body, and liquid-impermeable sheet as a single unit using the string-like members, so there is a risk of problems when folding the absorbent body that has absorbed bodily fluids and become heavy. In particular, in the case of the sanitary napkin disclosed in Patent Document 3, this may still be an acceptable problem, but it is difficult to fold an absorbent body that has absorbed a large amount of urine and become heavy, as in the case of a disposable diaper.

The absorbent article disclosed in Patent Document 4 has a backsheet consisting of two layers, an upper layer backsheet and a lower layer backsheet, and the lower layer backsheet has a central perforation along the approximate center line in the width direction and a bisection perforation that divides the lower layer backsheet into approximately two equal parts in the longitudinal direction, and multiple adhesive parts are formed on the clothing-facing surface of the lower layer backsheet. When the absorbent article is to be disposed of, the topsheet is folded inward, the bisection perforation and the central perforation in the right or left lower layer backsheet divided by the bisection perforation are broken, the broken lower layer backsheet is inverted, and the adhesive part of the broken lower layer backsheet is adhered to the unbroken lower layer backsheet and its adhesive part. Therefore, the absorbent article can be disposed of while maintaining the topsheet folded inward.

However, when disposing of the absorbent article disclosed in Patent Document 4, the worker must fold the top sheet, break the central perforation, turn over the lower back sheet, and glue the adhesive portion of the lower back sheet, which requires many steps and results in a problem of poor convenience.

Therefore, the object of the present invention is to provide an absorbent article that is highly effective in preventing the inner surface of the absorbent article, which has body fluids on it, from adhering to the worker's hands, etc., when it is disposed of.

The absorbent article that solves the above problems is as follows.
<First aspect>
An absorbent article having a crotch portion and a front portion and a rear portion extending on both the front and rear sides of the crotch portion,
A liquid permeable top sheet;
A liquid-impermeable back sheet;
an absorbent body interposed between the top sheet and the back sheet;
a pull-in member provided between the top sheet and the absorbent body and/or between the absorbent body and the back sheet, fixed to a rear portion of the absorbent body, and extending from the rear portion through the crotch area to the front portion;
The absorbent article is characterized in that, when the absorbent article is disposed of, the pulling body is pulled forward, and the rear portion of the absorbent body is pulled forward relative to the top sheet and the back sheet, thereby gathering the absorbent body at the front of the absorbent article.

(Action and Effect)
The absorbent article according to the present invention is provided with a pulling body extending from the rear portion through the crotch portion to the front portion, and the pulling body is fixed to the rear portion of the absorbent body. When disposing of this absorbent article, an operator can pull the pulling body to the front side, and pull the rear portion of the absorbent body arranged between the top sheet and the back sheet to the front side, and collect the absorbent body at the front side of the absorbent article. After that, for example, the rear portion that only has the top sheet and the back sheet (the rear portion of the absorbent article without the absorbent body) is folded back to the inner side to fold the absorbent article. In this way, when folding the absorbent article, the absorbent body that has become heavy by absorbing body fluids such as urine is no longer present at the rear portion of the absorbent article, and the rear portion of the top sheet is not pushed by the absorbent body and raised to the inner side. Therefore, when folding, there is little possibility that the wearer's hand will touch the top sheet and urine or the like will adhere to it.

<Second aspect>
An absorbent article having a crotch portion and a front portion and a rear portion extending on both the front and rear sides of the crotch portion,
A liquid permeable top sheet;
A liquid-impermeable back sheet;
an absorbent body interposed between the top sheet and the back sheet;
a pulling body which extends from the front portion through the crotch portion to the rear portion between the top sheet and the absorbent body, then rolls up a rear end of the rear portion of the absorbent body and turns from the inner side to the back side, and further extends from the rear portion through the crotch portion to the front portion between the absorbent body and the back sheet,
The absorbent article is characterized in that, when the absorbent article is disposed of, the pulling body is pulled forward, and the rear portion of the absorbent body is pulled forward relative to the top sheet and the back sheet, thereby gathering the absorbent body at the front of the absorbent article.

(Action and Effect)
In the first aspect, the attracting body was fixed to the rear portion of the absorbent body, but in the second aspect, the attracting body is arranged so as to wrap around the rear end of the rear portion of the absorbent body. In the first aspect, if the fixing force between the rear portion of the absorbent body and the attracting body is not sufficient, there is a risk that the attracting body will come off from the rear portion of the absorbent body, but in the second aspect, in principle, the rear portion of the absorbent body and the attracting body are not fixed, so there is no risk of the problem of the first aspect occurring.

<Third aspect>
The absorbent article according to the first or second aspect, wherein the pulling body is an elongated member made of a thermoplastic resin.

(Action and Effect)
Compared to a case where a string is provided as the pulling body, the manufacturing of an absorbent article is easier when the pulling body is made of a thermoplastic resin.

<Fourth aspect>
The absorbent article according to a second aspect, wherein at least a portion of the pulling body that is folded over the rear end of the rear portion of the absorbent body from the inner side to the back side is made of a sheet.

(Action and Effect)
In the case where the attracting body is arranged to wrap around the rear end of the rear part of the absorbent body as in the second embodiment, if the wrapped part is in a sheet shape, the contact area between the absorbent body and the attracting body increases, making it easier to attract the absorbent body. In other words, if the wrapped part of the attracting body has a long and thin shape like a string, when the absorbent body is attracted, the wrapped part of the attracting body may sink into the rear part of the absorbent body and cause part of the rear part of the absorbent body to break apart . This may make it difficult to move the entire rear part of the absorbent body to the front, but by making the wrapped part in a sheet shape as in the fourth embodiment, it is possible to prevent such problems from occurring.

<Fifth aspect>
The top sheet, the pulling body, and the back sheet each extend forward of the front end of the absorbent body and are integrally formed,
In that integrated part,
The top sheet and the back sheet are provided with a cut line extending across the pulling body in a width direction,
The portion in front of the cut line is a cutout portion,
The absorbent article of any one of the first to fourth aspects, wherein, when the absorbent article is disposed of, the cut-out portion is cut along the cut-out line and pulled forward, so that the rear portion of the absorbent body moves forward relative to the top sheet and the back sheet.

(Action and Effect)
The fifth aspect is characterized by the front portion of the pulling body. If a gap is provided between the top sheet and the back sheet at the front end of the absorbent article and the pulling body is pulled through the gap, there is a risk that urine may leak to the outside through the gap when the wearer urinates, for example.

In the fifth aspect, in order to prevent such problems, a gap is provided between the top sheet and the back sheet, and the structure does not involve pulling out the pull-out body through the gap. In other words, a cut line is provided on the top sheet and the back sheet that extends across the pull-out body in the width direction, and the portion in front of the cut line is the cut-out portion. Then, when disposing of the absorbent article, the cut-out portion is cut along the cut line, and then the cut-out portion is pulled forward, moving the rear portion of the absorbent body forward. With this structure, it is no longer necessary to provide a gap between the top sheet and the back sheet in advance, and leakage of bodily fluids through the gap can be prevented.

In addition, in a configuration in which the pulling body is pulled out from the gap between the top sheet and the back sheet, if the pulling body has a long and thin shape like a string, it is difficult to find the pulling body placed in the gap. In addition, when pulling out the long and thin pulling body, the worker must grasp the pulling body with their fingers and pull it out, which can be difficult for elderly people in particular.

This embodiment has a cutout, so there is little chance of the user having difficulty finding the location where the attracting body is placed. In addition, all that is required is to hold the cutout and move it forward, so even elderly people can easily attract the attracting body.

<Sixth aspect>
The absorbent article has a three-dimensional gather having an elongated elastic stretchable member and a gather sheet that are stretchable in the front-rear direction,
The three-dimensional gathers are arranged on both sides in the width direction of the absorbent article,
The absorbent article of any one of the first to fourth aspects, wherein the gathered sheet is fixed in a laid-down state to the inner surface of the absorbent article at both front-to-rear end portions of the absorbent article, and the gathered sheet is not fixed to the inner surface of the absorbent article at the middle part of the front-to-rear direction of the absorbent article, and the elongated elastic stretchable member is provided in the unfixed part, and the gathered sheet stands up relative to the use surface of the absorbent article as the elongated elastic stretchable member contracts in the front-to-rear direction.

(Action and Effect)
This embodiment is characterized in that the absorbent article is provided with three-dimensional gathers. After the worker pulls the rear portion of the absorbent body to the front, the absorbent body is not present in the rear portion of the absorbent article, making it lighter. Therefore, the rear portion of the absorbent article automatically collapses to the inner side due to the front-rear contraction force of the elongated elastic and stretchable member provided in the three-dimensional gathers, and faces the inner surface of the front portion of the absorbent article. Therefore, after the worker pulls the rear portion of the absorbent body, the absorbent article is automatically folded without the worker having to touch it, and in the folded state, the soiled inner surface of the absorbent article is covered with the back sheet, so there is little risk of urine or other body fluids adhering to the worker's hands.

As described above, the present invention provides an absorbent article that is highly effective in preventing the inner surface of the absorbent article, which has body fluids on it, from adhering to the worker's hands, etc., when disposed of.

Below, examples of absorbent articles are described in detail with reference to the attached drawings.

(Groin area, front part, back part)
The term "crotch area" refers to the area that corresponds to the crotch of the body when in use, and depending on the product, it may be the range from the center or vicinity of the center in the front-to-back direction LD of the article to a specified area on the front side as in the illustrated embodiment, or it may be a specified range in the center of the front-to-back direction LD of the article. If there is a narrow waist part in the middle of the front-to-back direction LD of the article or in the middle of the front-to-back direction LD of the absorbent, it means a specified range in the front-to-back direction with the narrowest part of either or both waist parts being the center in the front-to-back direction. In addition, "front part (ventral part)" refers to the part in front of the crotch area, and "rear part (dorsal part)" refers to the part behind the crotch area.

(Joining Means)
The joining means for joining the components can be, for example, an adhesive, and can be formed by solid, bead, curtain, summit or spiral application of hot melt adhesive, or pattern coating (transfer of hot melt adhesive using letterpress printing), or alternatively or in addition, by application to the outer circumferential surface of the elastic member using a comb gun or SureWrap. Hot melt adhesives include, for example, EVA-based, adhesive rubber-based (elastomer-based), olefin-based, polyester/polyamide-based, and the like, and can be used without any particular limitation. The joining means for joining the components can also be material welding means such as heat sealing or ultrasonic sealing.

(Basic structure of pad-type disposable diapers)
1 to 4 show a pad-type disposable diaper 200 as an example of an absorbent article. This pad-type disposable diaper 200 has a crotch portion C2 and a front portion F2 and a rear portion B2 extending on both the front and rear sides of the crotch portion C2. The dimensions of each portion can be appropriately determined. For example, the total length (length in the front-rear direction) L of the article can be about 350 to 700 mm, and the total width W1 can be about 130 to 400 mm (but wider than the width of the absorbing surface of the diaper). In this case, the length in the front-rear direction of the crotch portion C2 can be about 10 to 150 mm, the length in the front-rear direction of the front portion F2 can be about 50 to 350 mm, and the length in the front-rear direction of the rear portion B2 can be about 50 to 350 mm. The width W3 of the crotch portion C2 can be 150 mm or more, particularly about 200 to 260 mm, for an adult.

The pad-type disposable diaper 200 has a basic structure in which an absorbent body 23 is sandwiched between a liquid-permeable top sheet 22 and a liquid-impermeable outer sheet 21.

(Outer sheet)
An outer sheet 21 is provided on the back side of the absorbent body 23 so as to slightly protrude beyond the periphery of the absorbent body 23. As the outer sheet 21, in addition to a polyethylene film or the like, a sheet having moisture permeability without impairing water impermeability can also be used to prevent stuffiness. This water impermeable and moisture permeable sheet can be, for example, a microporous sheet obtained by melt-kneading an inorganic filler in an olefin resin such as polyethylene or polypropylene to form a sheet, and then stretching the sheet in a uniaxial or biaxial direction.

(Exterior sheet)
The outer surface of the outer sheet 21 is covered with an exterior sheet 27 made of nonwoven fabric, and this exterior sheet 27 protrudes outward from the peripheral edge of the outer sheet 21 with a predetermined protrusion width. Various types of nonwoven fabric can be used as the exterior sheet 27. As the material fiber constituting the nonwoven fabric, synthetic fibers such as olefin-based fibers such as polyethylene or polypropylene, polyester-based fibers, polyamide-based fibers, regenerated fibers such as rayon or cupra, and natural fibers such as cotton can be used. The exterior sheet 27 can also be omitted.

(Back seat)
The sheet located on the back side of the absorbent body 23 is called the back sheet 10, and this back sheet 10 includes the outer sheet 21 and the exterior sheet 27. In other words, the back sheet 10 is a generic concept that includes the outer sheet 21 and the exterior sheet 27. The back sheet 10 does not include the packaging sheet 26.

(Top sheet)
The front side of the absorbent 23 is covered with a top sheet 22 having liquid permeability. In the illustrated embodiment, the absorbent 23 partially protrudes from the side edge of the top sheet 22, but the width of the top sheet 22 can be increased so that the side edge of the absorbent 23 does not protrude. Various nonwoven fabrics can be used as the top sheet 22. The constituent fibers of the nonwoven fabric may be short fibers or long fibers (continuous fibers), and synthetic fibers such as olefins, polyesters, and amides such as polyethylene or polypropylene (which may be single-component fibers or composite fibers such as core-sheath structures made of multiple components), regenerated fibers such as rayon and cupra, and natural fibers such as cotton can be used. In addition, the method of bonding the fibers of the nonwoven fabric is not particularly limited, and chemical means such as adhesives and solvents, or physical means such as mechanical entanglement and thermal bonding can be used. One of the nonwoven fabrics preferable for the top sheet is an air-through nonwoven fabric formed by hot air bonding of thermoplastic synthetic fibers. Details of the top sheet 22 will be described later.

(middle seat)
It is preferable to interpose an intermediate sheet 25 between the top sheet 22 and the absorbent body 23. This intermediate sheet 25 is provided to prevent the return of urine absorbed by the absorbent body 23, and is preferably made of a material with low water retention and high liquid permeability, such as various nonwoven fabrics and mesh films. When the front end of the top sheet 22 is 0% and the rear end of the top sheet 22 is 100%, the front end of the intermediate sheet 25 is preferably located in a range of 0 to 11%, and the rear end of the intermediate sheet 25 is preferably located in a range of 92 to 100%. In addition, it is preferable that the width W4 of the intermediate sheet 25 is about 50 to 100% of the minimum width W5 of the constricted portion 23n of the absorbent body 23 described later. The intermediate sheet 25 can be omitted.

(End flap, side flap, three-dimensional gathers)
At both ends in the front-rear direction LD of the pad-type disposable diaper 200, the exterior sheet 27 and the top sheet 22 are attached to each other, extending forward and backward beyond the front and rear ends of the absorbent 23, to form end flap portions EF where the absorbent 23 is not present. At both sides of the pad-type disposable diaper 200, the exterior sheet 27 extends outward beyond the side edges of the absorbent 23, and the outer portions 24x of the gather sheets 24s forming the three-dimensional gathers 24 in the width direction WD are attached to the inner surface of the portion from the extension portion to the side portion of the top sheet 22 over the entire front-rear direction LD, forming side flap portions SF where the upper absorbent 23A and the lower absorbent 23B are not present. These attached portions can be formed by hot melt adhesive, heat sealing, or ultrasonic sealing. When the exterior sheet 27 is not provided, the outer sheet 21 can be extended to the side flap portions SF instead of the exterior sheet 27 to form the outer surface side of the side flap portions SF.

The material for the gathered sheet 24s can be a plastic sheet or meltblown nonwoven fabric, but in terms of feel on the skin, it is preferable to use nonwoven fabric that has been treated with a water-repellent agent such as silicone.

The widthwise center portion 24c of the gathered sheet 24s extends onto the top sheet 22, and at the end portion at the widthwise center, an elongated elastic member 24G is fixed in a stretched state along the front-to-rear direction with a hot melt adhesive or the like. The elongated elastic member 24G can be made of commonly used materials such as styrene-based rubber, olefin-based rubber, urethane-based rubber, ester-based rubber, polyurethane, polyethylene, polystyrene, styrene butadiene, silicone, polyester, etc., formed into thread, string, strip, etc.

In addition, the widthwise outer portions 24x of both gather sheets 24s are bonded and fixed to the inner surface of the article (the surface of the top sheet 22 and the inner surface of the exterior sheet 27 in the illustrated embodiment) over the entire front-to-rear direction, while the widthwise center portions 24c are bonded and fixed to the inner surface of the article (the surface of the top sheet 22 in the illustrated embodiment) at both ends in the front-to-rear direction, but are not fixed to the inner surface of the article (the surface of the top sheet 22 in the illustrated embodiment) between the both ends in the front-to-rear direction. This non-fixed portion is a portion that becomes a leak prevention wall that stands elastically against the inner surface of the article (the surface of the top sheet 22 in the illustrated embodiment), and its standing base end 24b is located at the boundary between the fixed portion 24x on the widthwise outer side of the gather sheet 24s and its inner portion 24c.

(Absorber)
The absorbent body 23 may be a pulp fiber stack, a filament aggregate such as cellulose acetate, or a nonwoven fabric, with particulate or other highly absorbent polymer particles mixed or fixed as necessary. The absorbent body 23 is not limited to a single-layer structure as shown in the figure, and may be, for example, a two-layer structure consisting of a lower absorbent body and an upper absorbent body provided on the skin side (front side) thereof, or a structure of three or more layers. In the case of a two-layer structure consisting of an upper absorbent body and a lower absorbent body, the lower absorbent body is preferably an accumulation of at least pulp fibers, and is particularly preferably a mixed accumulation of pulp fibers and highly absorbent polymer particles. On the other hand, the upper absorbent body is preferably a mixed accumulation of pulp fibers and highly absorbent polymer particles.

The superabsorbent polymer particles contained in the absorbent body can be the same as those used in this type of absorbent article. In normal cases, when sieving (shaking for 5 minutes) using a 500 μm standard sieve (JIS Z8801-1:2006) and sieving (shaking for 5 minutes) the particles that fall below the sieving sieve using a 180 μm standard sieve (JIS Z8801-1:2006), it is desirable that the proportion of particles remaining on the 500 μm standard sieve is 30% by weight or less and the proportion of particles remaining on the 180 μm standard sieve is 60% by weight or more.

The highly absorbent polymer particles are not particularly limited, but those with a water absorption speed of 20 to 50 seconds and a water absorption capacity of 50 to 80 g/g can be suitably used. Examples of highly absorbent polymer particles include starch-based, cellulose-based and synthetic polymer-based particles, and those that can be used include starch-acrylic acid (salt) graft copolymers, saponified starch-acrylonitrile copolymers, crosslinked products of sodium carboxymethylcellulose and acrylic acid (salt) polymers.

If necessary, the absorbent body 23 can be wrapped, either integrally or individually, in a wrapping sheet 26 that has liquid permeability and liquid retention, such as crepe paper, for the purpose of maintaining the shape and the superabsorbent polymer particles.

The absorbent body 23 extends from the front portion F2 through the crotch portion C2 to the rear portion B2. The shape of the absorbent body can be determined as appropriate, and can be rectangular, but it is preferable that a predetermined portion in the middle in the front-rear direction including the crotch portion C2 is formed as a narrow constricted portion 23n. The minimum width W5 of this constricted portion 23n is preferably about 50-65% of the width W2 of the non-constricted portion located in front of and behind the constricted portion 23n. In addition, when the front end of the article is 0% and the rear end of the article is 100%, the front end of the constricted portion 23n is preferably located in the range of 10-25%, the rear end of the constricted portion 23n is preferably located in the range of 40-65%, and the portion of the constricted portion 23n that has the minimum width W5 (minimum width portion) is preferably located in the range of 25-30%. Although not shown, a slit of a predetermined width may be provided in the front-rear direction in the front-rear region of the absorbent body 23 that corresponds to the crotch portion C2.

First Embodiment
Next, an absorbent article (absorbent pad) of a first embodiment will be described with reference to Figures 1 to 4. In the absorbent pad of the first embodiment, one attracting body 30 is disposed between the top sheet 22 and the absorbent body 23, and one attracting body 30 is also disposed between the absorbent body 23 and the outer sheet 21 (back sheet 10). One end of the attracting body 30 is fixed to the rear side of the rear part B2 of the absorbent body 23 in the front-rear direction LD, and the attracting body 30 extends from the rear part B2 through the crotch part C2 to the front part F2, and the other end of the attracting body 30 is located at the front edge of the front part F2. In addition, the attracting body 30 is provided in the center part in the width direction WD.

In the present invention, the meaning of the attraction body 30 being fixed to the absorbent body 23 is that when the absorbent body 23 is wrapped in the packaging sheet 26, the attraction body 30 is fixed to the outer surface of the packaging sheet 26 (not the surface in contact with the absorbent body 23, but the surface opposite to it) (the attraction body 30 is indirectly fixed to the absorbent body 23 with the packaging sheet 26 interposed therebetween), and when the absorbent body 23 is not wrapped in the packaging sheet 26, the attraction body 30 is fixed directly to the surface of the absorbent body 23.

The method of fixing the attracting body 30 to the absorbent body 23 is not particularly limited, and examples include adhesives. Specifically, it is formed by solid, bead, curtain, summit or spiral application of hot melt adhesive, or pattern coating (transfer of hot melt adhesive using letterpress printing). There are various types of hot melt adhesive, such as EVA-based, adhesive rubber-based (elastomer-based), olefin-based, and polyester/polyamide-based, and any type can be used without particular limitations. In addition, material welding methods such as heat sealing and ultrasonic sealing can also be used.

If the fixing area between the attracting body 30 and the absorbent body 23 is small, the attracting body 30 may peel off from the absorbent body 23 when the absorbent body 23 is pulled forward in the front-rear direction LD. Therefore, it is preferable that the fixing area is sufficient. Specifically, it is preferable that the fixing area is 100 mm ² or more, and more preferably 1125 mm ² or more. In particular, when the shape of the attracting body 30 is elongated in the front-rear direction LD as in the first embodiment, if the length of the width direction WD of the attracting body 30 is short, it tends to be difficult to secure a sufficient fixing area even if the entire width of the attracting body 30 is fixed. Therefore, it is preferable to secure a certain length in the width direction WD of the attracting body 30. Specifically, it is preferable that the length of the width direction WD of the attracting body 30 is 15 mm or more, and more preferably 30 mm or more. Furthermore, when the length of the attracting body 30 in the width direction WD is short, in order to ensure a sufficient fixing area, it is preferable to fix the entire width of the attracting body 30 to the absorbent body 23 and to increase the length in the front-rear direction LD of the fixing portion 31 of the attracting body 30 and the absorbent body 23. For example, when the length of the fixing portion 31 of the attracting body 30 in the width direction WD is about 15 mm to 30 mm, it is preferable to set the length of the fixing portion 31 of the attracting body 30 in the front-rear direction LD to about 50 mm to 75 mm.

The fixing point of the attracting body 30 and the absorbent body 23 is preferably the rear part of the attracting body 30 in the front-rear direction LD. Considering the purpose of pulling the rear part B2 of the absorbent body 23 forward in the front-rear direction LD, the further the fixing point of the attracting body 30 and the absorbent body 23 is on the rear side in the front-rear direction LD of the absorbent body 23, the more the rear part B2 of the absorbent body 23 can be pulled forward without any waste. From the above viewpoint, it is preferable to set the length from the rear edge of the absorbent body 23 in the front-rear direction LD to the fixing part 31 of the attracting body 30 and the absorbent body 23 (more specifically, the rear edge of the fixing part 31 in the front-rear direction LD) to within 50 mm, and more preferably within 25 mm.

It is also preferable that the attraction body 30 and the absorbent body 23 are fixed only to the rear part B2 of the absorbent body 23. If the attraction body 30 is also fixed to the crotch part C2 or front part F2 of the absorbent body 23, the force is easily transmitted to the front part F2 located near the hand of the worker pulling the attraction body 30, so the front part F2 is easy to move forward, but the farther it is from the worker's hand, the less the pulling force is directly transmitted, making it difficult to move the rear part F2, which is the most desired part to move, forward. In addition, the crotch part C2 and the front part F2, which do not need to be moved, are actively moved forward, so a stronger force is required when the worker pulls the attraction body 30. In particular, the crotch portion C2 and the front portion F2 that have absorbed urine and the like are inflated and pushing the top sheet 22 and the back sheet 10 outward in the thickness direction TW, so that the frictional forces between the top sheet 22 and the absorbent body 23 and between the absorbent body 23 and the back sheet 10 are strong, and if the crotch portion C2 and the front portion F2 are actively moved forward, a stronger force is required when pulling them in. The fastening point between the pulling body 30 and the absorbent body 23 is only the rear side of the rear portion B2 of the absorbent body 23, and it is preferable that the front side of the rear portion B2 of the absorbent body 23 is not fastened to the pulling body 30. Specifically, it is preferable to fasten a portion of about 50 mm from the rear end edge of the pulling body 30 in the front-rear direction LD to the front side to the absorbent body 23, and more preferably a portion of about 25 mm to the absorbent body 23.

In the first embodiment, the attracting body 30 is a single elongated strip-shaped member extending in the front-rear direction LD. As the attracting body 30, for example, a strip-shaped member (or string-shaped member; the same applies below) made of cotton, hemp, rubber, paper, etc. can be used, but when manufacturing an absorbent article, it is difficult to pinpoint the attracting body 30 made of these strings and then attach it to the rear part B2 of the absorbent body 23 after placing it at a predetermined position of the absorbent article. This is because in the manufacturing line, a belt conveyor carrying the absorbent body 23, etc. moves at high speed. Therefore, in consideration of the ease of manufacturing the absorbent article, it is preferable to use a strip-shaped member made of thermoplastic resin as the attracting body 30. Thermoplastic resin has higher mechanical properties than cotton and paper, so it can withstand overloads such as pulling materials during production, and has the advantage that the attracting body 30 is automatically attached to the absorbent body 23 during the process of cooling the thermoplastic resin. In order to fix the puller 30 made of a thermoplastic resin only to the rear portion B2 of the absorbent body 23 and not to the crotch portion C2 or the front portion F2, a known agent for preventing adhesion may be applied to the surface of the crotch portion C2 or the front portion F2 of the absorbent body 23. Examples of such thermoplastic resins include polystyrene, polymethyl methacrylate, and polycarbonate. In particular, it is preferable to use polystyrene or polymethyl methacrylate because they have a lower heat distortion temperature than other thermoplastic resins and have a higher tensile strength and elastic modulus.

In the first embodiment, the pull-in body 30 is provided between the top sheet 22 and the absorbent body 23, and also between the absorbent body 23 and the outer sheet 21 (back sheet 10), but it may be provided on only one of them. However, if it is provided on only one of them, the ability to move the rear part B2 of the absorbent body 23 forward is reduced, so it is preferable to provide it on both as much as possible, as in the first embodiment. If it is provided on only one of them, it is preferable to provide it between the absorbent body 23 and the outer sheet 21 (back sheet 10). Since the absorbent body 23 that has absorbed body fluids such as urine becomes heavy due to gravity, it is easier to pull it by supporting the underside of the absorbent body 23 with the pull-in body 30.

Second Embodiment
Next, an absorbent article (absorbent pad) of a second embodiment will be described with reference to Figs. 5 and 6. Note that the description of the contents overlapping with the first embodiment will be omitted. The attracting body 30 of the second embodiment extends from the front side of the front end edge of the front part F2 of the absorbent 23 between the top sheet 22 and the absorbent body 23 (more precisely, between the top sheet 22 and the packaging sheet 26 because the absorbent body 23 is wrapped in the packaging sheet 26) to the rear end edge of the rear part B2 of the absorbent body 23 through the crotch part C2. The attracting body 30 that extends to the rear end edge of the rear part B2 of the absorbent body 23 then wraps around the rear end of the rear part B2 of the absorbent body 23 and is returned from the inner side to the rear side. That is, it extends from the front side to the rear side in the thickness direction TW through the side edge of the rear end of the rear part B2 of the absorbent body 23. The pulling body 30 that has been turned to the back side extends further between the absorbent body 23 and the back sheet 10 (more precisely, between the packaging sheet 26 and the back sheet 10 (outer sheet 21) since the absorbent body 23 is wrapped in the packaging sheet 26), from the rear edge of the rear portion B2 of the absorbent body 23, through the crotch area C2, and further forward than the front edge of the front portion F2 of the absorbent body 23.

The second embodiment is characterized in that the attracting body 30 between the top sheet 22 and the absorbent body 23 is connected to the attracting body 30 between the absorbent body 23 and the back sheet 10. Another characteristic is that the connected portion is a portion that wraps around the rear end of the rear portion B2 of the absorbent body 23. Another characteristic is that the attracting body 30 is not fixed to the absorbent body 23 directly or indirectly.

In the second embodiment having such a configuration, when the attracting body 30 is attracted forward, the rear end of the attracting body 30 captures the rear edge of the absorbent body 23 while attracting the rear portion B2 of the absorbent body 23 forward. In this way, the attracting body 30 attracts the rear portion B2 of the absorbent body 23 forward while grasping the rear edge of the absorbent body 23, which has the advantage of providing a stronger attracting force than the first embodiment.

In addition, in the first embodiment, only one attracting body 30 was provided in the center of the width direction WD, but in the second embodiment, one attracting body 30 is provided at each of the positions that divide the width direction WD into approximately three equal parts (two in total). Therefore, the balance of the attracting body 30 in the width direction WD is better than in the first embodiment, and from that point of view, there is an advantage that the attracting force is stronger than in the first embodiment.

Third Embodiment
Next, an absorbent article (absorbent pad) of the third embodiment will be described with reference to Figs. 7 and 8. Note that the description of the contents overlapping with the first and second embodiments will be omitted. This third embodiment is a modification of the second embodiment, and the rear side of the rear part B2 of the attracting body 30 of the second embodiment is made into a sheet shape. In this way, by making the rear side of the rear part B2 of the attracting body 30 into a sheet shape, the contact area between the rear end of the attracting body 30 and the rear end of the absorbent body 23 is increased, and the force with which the rear end of the attracting body 30 captures the rear end edge of the absorbent body 23 is strengthened, so that the rear part B2 of the absorbent body 23 is more easily attracted to the front side than in the second embodiment. In particular, if the attracting body 30 has an elongated shape as in the second embodiment, when the absorbent body 23 is attracted, the rear end edge of the attracting body 30 may sink into the rear end of the absorbent body 23, causing the rear part B2 of the absorbent body 23 to break apart (this is particularly noticeable when the absorbent body 23 is not wrapped in a packaging sheet 26). As in the third embodiment, by forming the rear side of the pulling body 30 in the front-rear direction LD into a sheet shape, it is possible to reduce the probability of the sinking occurring as in the second embodiment.

In the third embodiment, it is preferable that the length in the front-rear direction LD of the sheet portion 30S of the attracting body 30 is not too long. If the distance that the sheet portion 30S extends from the rear edge of the absorbent body 23 to the front in the front-rear direction LD becomes too long, for example, when the wearer urinates, the sheet portion 30S of the attracting body 30 may hinder the movement of urine to the absorbent body 23. Therefore, the length in the front-rear direction LD of the sheet portion 30S is preferably within a range of 40 mm, and more preferably within a range of 20 mm, from the position of the rear edge of the absorbent body 23 to the front in the front-rear direction LD.

In the embodiment shown in FIG. 7, the length of the sheet portion 30S of the attracting body 30 in the width direction WD is increased, and the elongated portions 30L of the attracting body 30, one on each side in the width direction WD, are connected by this sheet portion 30S. However, this is not necessarily limited to such a shape, and the elongated portions 30L of the attracting body 30 do not necessarily have to be connected by the sheet portion 30S.

However, when the pulling body 30 is pulled, the longer the length in the width direction WD of the sheet portion 30S that contacts the rear edge portion of the absorbent body 23, the higher the pulling ability of the absorbent body 23. Therefore, it is preferable to make the length in the width direction WD of the sheet portion 30S that contacts the rear edge portion of the absorbent body 23 as long as possible. Specifically, the length in the width direction WD of the sheet portion 30S that contacts the rear edge portion of the absorbent body 23 is preferably 40% to 80% of the length in the width direction WD of the rear edge portion of the absorbent body 23, and more preferably 70% to 80%. Specifically, the length in the width direction WD of the sheet portion 30S that contacts the rear edge portion of the absorbent body 23 is preferably about 96 mm to 192 mm, and more preferably about 168 mm to 192 mm.

The rear end of the sheet portion 30S of the pull-in body 30 is wrapped around the rear end of the rear portion B2 of the absorbent body 23 and turned from the inner side to the rear side, similar to the second embodiment.

Fourth Embodiment
Next, an absorbent article (absorbent pad) of a fourth embodiment will be described with reference to Figures 9 to 11. In the fourth embodiment, a cutout portion 36 is provided in the front portion F2 of the absorbent article. In detail, the top sheet 22, the pulling body 30, and the back sheet 10 (the outer sheet 27 of the back sheet 10) each extend further forward than the front end of the absorbent body 23, and the pulling body 30 is sandwiched between the top sheet 22 and the back sheet 10. In this portion (in a portion further forward than the front end of the absorbent body 23), a cutout line 35 is provided for the top sheet 22 and the back sheet 10, which extends across the pulling body 30 in the width direction WD.

9 and 10, the cut line 35 may extend in a substantially straight line from the left edge of the absorbent article in the width direction WD and the front edge of the absorbent article in the front-rear direction LD to the rear side in the front-rear direction LD (not extending to the front edge of the absorbent body 23), then change direction and extend in a substantially straight line to the right side in the width direction WD, straddling two pulling bodies 30 in the process of extending, and then change direction again and extend in a substantially straight line to the front side in the front-rear direction LD, terminating at the right edge of the absorbent article in the width direction WD and the front edge of the absorbent article in the front-rear direction LD, as shown in FIG. 11. Alternatively, the cut line 35 may extend in a substantially straight line from the left edge of the absorbent article in the width direction WD to the right edge in the front-rear direction LD in the part further forward than the front end of the absorbent body 23, straddling two pulling bodies 30 in the process of extending. In the above description, the cut line 35 is formed in a substantially straight line ("substantially straight line" includes "straight line" and "line close to straight line"), but it may be modified as appropriate, such as being curved.

The cut line 35 can be formed, for example, by a through hole that passes through the top sheet 22 and the back sheet 10 at a predetermined interval. In a plan view, the through hole of the cut line 35 is formed in a dotted line. A through hole may be formed in a part of the attracting body 30 at the cut line 35, but considering that the attracting body 30 pulls the absorbent body 23 forward, it is preferable not to provide a through hole for the cut line 35 in the attracting body 30 so that the attracting body 30 does not break.

As shown in Figures 9 to 11, a cutout portion 36 is formed in the portion forward of the cutout line 35. A worker who disposes of the absorbent article cuts out the cutout portion 36 along the cutout line 35 and pulls the cutout portion 36 forward, thereby moving the rear portion B2 of the absorbent body 23 forward.

As shown in FIG. 10, it is preferable that the top sheet 22, the back sheet 10, and the attracting body 30 are bonded at the cutout portion 36, and the attracting body 30 is not bonded to the top sheet 22 or the back sheet 10 in the rear portion of the cutout portion 36. By bonding the top sheet 22, the back sheet 10, and the attracting body 30 at the cutout portion 36, it is possible to prevent body fluids such as urine from leaking out from the gap between the top sheet 22, the back sheet 10, and the attracting body 30 of the absorbent article. In addition, by not bonding the attracting body 30 to the top sheet 22 or the back sheet 10 in the rear portion of the cutout portion 36, when the cutout portion 36 is cut and moved forward, only the rear portion B2 of the absorbent body 23 can be moved forward while keeping the top sheet 22 and the back sheet 10 in their original positions.

(Disposal method)
Next, the disposal process of an absorbent article (absorbent pad) will be described with reference to Figures 12 to 15. When disposing of an absorbent article, the puller 30 is pulled forward in the front-to-rear direction LD, and while keeping the top sheet 22 and the back sheet 10 in their original positions, the rear portion B2 of the absorbent body 23 is pulled forward relative to the top sheet 22 and the back sheet 10, so that the absorbent body 23 is gathered at the front of the absorbent article. If a cut line 35 is provided, the top sheet 22 and the back sheet 10 are cut along the cut line 35, and the cut portion 36 is pulled forward.

Figure 15 shows a cross-sectional view of the state after the rear portion B2 of the absorbent body 23 has been pulled forward. Note that Figure 15 shows an example in which the puller 30 is provided only between the absorbent body 23 and the back sheet 10. In this way, when the rear portion B2 of the absorbent body 23 is pulled forward, not only the rear portion B2 of the absorbent body 23 but also the crotch portion C2 and front portion F2 of the absorbent body 23 are pushed by the rear portion B2 of the absorbent body 23 and move forward, resulting in the absorbent body 23 gathering at the front of the absorbent article in the front-to-rear direction LD.

After this state is reached, the worker can fold the absorbent article by grasping the rear portion B2 of the absorbent article and folding it in half toward the inner surface of the front portion F2 of the absorbent article, as shown by the dotted arrows in Figure 15. After folding, the front portion F2 and rear portion B2 of the top sheet 22 of the absorbent article that is soiled with urine or the like are positioned on the inside and facing each other, and the outside is covered by the back sheet 10 of the absorbent article that is not soiled with urine or the like. The worker can then grab the back sheet 10 of the absorbent article in this state and dispose of it.

As described above, in the process of disposing of the absorbent article, by pulling the puller 30 forward to move the rear portion B2 of the absorbent 23 forward, the absorbent 23 is not present in the rear portion B2 of the absorbent article as shown in Fig. 15, and therefore the top sheet 22 of the rear portion B2 of the absorbent article is not raised. Therefore, when the rear portion B2 of the absorbent article is picked up and folded in half toward the inner surface of the front portion F2 of the absorbent article , urine or the like adhering to the surface of the top sheet 22 is less likely to come into contact with the worker's hands.

If the absorbent article is provided with the above-mentioned three-dimensional gathers, disposal becomes easier. That is, in the process of disposing of the absorbent article, when the puller 30 is pulled forward to move the rear part B2 of the absorbent body 23 to the front, the absorbent body 23 that has become heavy by absorbing urine and the like is not present in the rear part B2 of the absorbent article, and the weight of the rear part B2 of the absorbent article becomes light overall. Then, the contraction force of the elongated elastic member 24G of the three-dimensional gathers in the front-rear direction LD acts, and the rear part B2 of the absorbent article is automatically folded in half toward the inner surface of the front part F2 of the absorbent article. Therefore, the worker does not even need to pick up the rear part B2 of the absorbent article and fold it in half toward the inner surface of the front part F2 of the absorbent article , so that the risk of urine or the like adhering to the surface of the top sheet 22 coming into contact with the worker's hands is further reduced.

<Explanation of terms used in the specification>
When used in this specification, the following terms have the following meanings, unless otherwise specified in the specification.
- "Front-to-back (vertical) direction" means the direction connecting the ventral side (front) and the dorsal side (rear), and "width direction" means the direction perpendicular to the front-to-back direction (left-right direction).
- "MD direction (machine direction or line flow direction)" and "CD direction (horizontal direction perpendicular to MD direction)" in the manufacturing method mean the "MD direction" and "CD direction" of the processing equipment of the convex portion 31, one of which is the front-rear direction and the other is the width direction. The MD direction in the product is the direction of fiber orientation of the nonwoven fabric. Fiber orientation is the direction along which the fibers of the nonwoven fabric are aligned, and can be determined, for example, by a measurement method based on the fiber orientation test method based on the zero-distance tensile strength of TAPPI standard method T481, or a simple measurement method that determines the fiber orientation direction from the tensile strength ratio in the front-rear direction and the width direction. In the illustrated form, like most disposable diaper products, the front-rear direction is the MD direction and the width direction is the CD direction.
"Deployed state" means a flat deployed state without contraction or sagging.
The "thickness" of the top sheet means the "apparent thickness" and is measured by the following method. That is, when measuring, a measuring piece of 30 mm length x 30 mm width is cut out. At this time, a cut surface passing through the measurement part is made. For example, when measuring the apparent thickness of a part of the top sheet excluding the peripheral part of the through hole, a cut surface is formed that is parallel to the MD direction and does not pass through the through hole and its peripheral part. Then, an enlarged photograph of this cut surface is taken using a digital microscope VHX-1000 manufactured by Keyence Corporation, and the apparent thickness of the target part of the top sheet is measured based on this enlarged photograph. When determining the maximum and minimum values, measurements are made at 10 or more points, and the maximum and minimum values are determined.
The "thickness" of the absorbent is measured using a thickness gauge from Ozaki Manufacturing Co., Ltd. (Peacock, large dial thickness gauge, model J-B (measurement range 0 to 35 mm) or model K-4 (measurement range 0 to 50 mm)) with the sample and the thickness gauge held horizontally.
"Thickness" other than the above is automatically measured using an automatic thickness measuring device (KES-G5 handy compression measurement program) under the conditions of a load of 0.098 N/cm ² and a pressurized area of 2 cm ² .
The water absorption amount is measured according to JIS K7223-1996 "Test method for water absorption amount of superabsorbent resin".
The water absorption rate is the "time to the end point" when 2 g of superabsorbent polymer and 50 g of physiological saline are used and the "Test method for water absorption rate of superabsorbent resin" according to JIS K7224-1996 is performed.
・Unless otherwise specified, the dimensions of each part refer to the dimensions in the unfolded state, not in the natural length state.

The present invention can be used for any type of disposable diaper, including pad-type disposable diapers such as the above example, tape-type disposable diapers, pants-type disposable diapers, etc. It can also be used for absorbent articles other than disposable diapers, such as sanitary napkins.
