Description

The present invention relates to a disposable wearable article.

Connected disposable wearable articles generally have side gathers that rise toward the body and extend in the front-to-rear direction on both sides of the width of the surface (see, for example, Patent Documents 1 and 2). By providing such side gathers, body waste is trapped between the two side gathers, and leakage of body waste from around the wearer's legs is particularly prevented.

In general, connected disposable wearable articles have poorer fit around the waist compared to pants-type disposable wearable articles, so to prevent leakage from the back or stomach, it is known to provide elastic waist areas or provide three-dimensional waist gathers that rise toward the body along the width direction at the rear end of the rising part of the side three-dimensional gathers (see, for example, Patent Document 1).

However, conventional disposable connected wearable articles have the problem that gaps are easily formed behind the raised portion of the side three-dimensional gathers, and if body waste exceeds the three-dimensional waist gathers, it leaks out from the rear end of the product (rear leakage or back leakage). In addition, when the absorbent body absorbs excrement and increases in thickness, the raised height of the three-dimensional waist gathers becomes lower relative to the surface of the product on the crotch side, which makes it easier for body waste to go over the three-dimensional waist gathers.

To solve this problem, it was considered to add three-dimensional waist gathers behind the raised parts of the side gathers, but if the three-dimensional waist gathers at the back only held back the excrement, there was a risk that the held back excrement would cause skin trouble, or that the excrement would end up leaking out if a gap formed between the three-dimensional waist gathers at the back and the skin.

On the other hand, similar problems (front leakage or abdominal leakage) occurred not only at the rear of the product but also at the front of the product.

JP 2010-22587 A JP 2016-32591 A

The main objective of the present invention is to improve the effectiveness of preventing rear or front leakage in connected disposable wearable articles.

The following disposable jointable wearable article has been developed to solve the above problems.
<First aspect>
The garment has a crotch portion including a center in the front-to-rear direction, a ventral portion extending forward from the center in the front-to-rear direction, and a dorsal portion extending rearward from the center in the front-to-rear direction,
The dorsal portion has connecting portions provided on both sides thereof and detachably connected to an outer surface of the ventral portion,
An absorbent body is provided in an area including the crotch area,
A first waist three-dimensional gather is provided on the waist side of at least one of the back side portion and the ventral side portion, the first waist three-dimensional gather having a first rising portion rising from the surface along a first cut-off position along the width direction, and a second waist three-dimensional gather having a second rising portion rising from the surface along a second cut-off position along the width direction, the second rise-off portion being spaced away from the first cut-off position toward the crotch,
At least a part of the region extending from the first raised portion to the second raised portion has an absorbent layer having a superabsorbent polymer;
The excreted liquid that reaches the surface between the first raised portion and the second raised portion can be supplied to the absorbent layer.
A disposable wearable article comprising:

(Action and Effect)
In this article, a two-stage leakage prevention function is exhibited, in which the second waist three-dimensional gathers basically prevent the movement of excrement, and the first waist three-dimensional gathers prevent the leakage of excrement that has somehow passed over it. Characteristically, not only is the first waist three-dimensional gathers blocking excrement that has passed over the second waist three-dimensional gathers, but the blocked excrement can also be absorbed and retained by an absorbent layer provided at the blocking position (between the first and second rising parts). This makes it possible to prevent situations in which excrement blocked by the first waist three-dimensional gathers causes skin trouble, or where excrement once blocked ends up leaking out when a gap forms between the first waist three-dimensional gathers and the skin.

<Second aspect>
An end flap not having the absorbent body is provided on the waist side of the absorbent body in the back portion,
At least one of the first raised portion and the second raised portion has a front sheet layer and a back sheet layer extending to a waist root portion attached to the end flap,
an absorbent layer made only of the superabsorbent polymer is interposed between the front sheet layer and the back sheet layer in the waist base portion;
1. A disposable jointable wearing article according to a first aspect.

(Action and Effect)
The waist root portion is the lowest portion between the first and second raised portions, and is the portion where excrement that has passed over the second waist three-dimensional gathers is collected. Therefore, by incorporating an absorbent layer at least in the waist root portion as in this embodiment, the excrement blocked by the first waist three-dimensional gathers can be transferred to the absorbent layer more quickly. In addition, by arranging an absorbent layer made only of a highly absorbent polymer near the surface as in this embodiment, it is possible to prevent the deterioration of the fit due to an increase in thickness.

<Third aspect>
a top sheet layer located on the top side of the absorbent layer,
The front sheet layer has a plurality of through holes formed at intervals and penetrating from the front to the back, and the absorbent layer is provided only between adjacent through holes.
The jointable disposable wearing article according to the first or second aspect.

(Action and Effect)
Not only does the excreted liquid easily reach the absorbent layer through the through-holes, but the absorbent layer that has absorbed the excreted liquid is covered by the front sheet layer, making it less likely to come into contact with the skin. Thus, according to this embodiment, both the prevention of skin troubles and the prevention of leakage are improved. In addition, when the highly absorbent polymer in the absorbent layer absorbs the excreted liquid and expands, the front sheet layer is lifted, making it easier for the excreted matter to be introduced into the absorbent layer through the through-holes. Note that the term "through-hole" does not include fiber gaps, but refers to holes formed by needle piercing, slitting, or punching.

<Fourth aspect>
a top sheet layer located on the top side of the absorbent layer,
The front sheet layer has a through hole penetrating from the front to the back, and an opening/closing flap extending from a periphery of the through hole to cover the through hole.
The jointable disposable wearing article according to any one of the first to third aspects.

(Action and Effect)
Not only does this make it easier for excreted liquid to reach the absorbent layer through the through-holes, but the absorbent layer that has absorbed the excreted liquid is covered by the opening and closing flaps, making it less likely to come into contact with the skin. Thus, according to this embodiment, both the prevention of skin troubles and the prevention of leakage are improved.

<Fifth aspect>
At least a tip end of the first raised portion has a first three-dimensional elastic member,
At least a tip end of the first raised portion is contracted in the width direction together with the first three-dimensional elastic member and is extensible in the width direction,
The through holes are formed in a plurality of spaces in the width direction,
The base of the opening and closing flap is located on the waist side of the through hole,
A shrinkage wrinkle is formed in an area including a root of the opening and closing flap due to the influence of shrinkage of the first three-dimensional elastic member.
A disposable jointable wearing article according to a fourth aspect.

(Action and Effect)
When the aforementioned opening and closing flaps are arranged as in this embodiment and shrinkage wrinkles are formed in the area including the base of the opening and closing flaps due to the shrinkage of the first three-dimensional elastic member, the opening and closing flaps are lifted slightly to form gaps, making it easier for excreted liquid to reach the absorbent layer through the through holes.

<Sixth aspect>
The garment has three-dimensional side gathers rising from the surface along a third cut-off position extending in the front-rear direction on both sides in the width direction,
The side three-dimensional gathers include a side root portion attached to the outside of the third blocking position in the width direction, a side main portion extending from the side root portion, a side fallen portion formed by fixing a front end portion and a rear end portion of the side main portion in a fallen state, a side rising portion formed by leaving a portion between the front and rear side fallen portions of the side main portion unfixed, and a side three-dimensional elastic member attached to at least a tip portion of the side rising portion,
At least the tip end of the side rising portion is contracted in the front-rear direction together with the side three-dimensional elastic member and is extensible in the front-rear direction,
The first blocking position is located between the side fallen portions arranged at intervals in the width direction,
The first waist three-dimensional gather has a waist root portion attached along the first blocking position, a first portion extending from the waist root portion toward the waist edge side, a first fallen portion formed by fixing both ends in a fallen state of the first portion, a first raised portion formed by leaving a portion of the first portion between the first fallen portions unfixed, and a first three-dimensional elastic member attached to at least a tip portion of the first raised portion,
At least a tip end of the first raised portion is contracted in the width direction together with the first three-dimensional elastic member and is extensible in the width direction,
The second waist three-dimensional gather has a second portion extending from the waist root portion toward the crotch area, a second fallen portion formed by fixing both ends in a width direction of the second portion in a fallen state, a second raised portion formed by leaving a portion of the second portion between the second fallen portions unfixed, and a second three-dimensional elastic member attached to at least a tip end of the second raised portion,
At least a tip end of the second raised portion is contracted in the width direction together with the second three-dimensional elastic member and is extensible in the width direction.
The jointable disposable wearing article according to any one of the first to fifth aspects.

(Action and Effect)
The first waist three-dimensional gather of the present article is characterized by a combination of a first raised portion extending out toward the waist edge relative to the waist base portion and its attachment position being between side fallen portions spaced apart in the width direction.
That is, in the present first waist three-dimensional gathers, as the first rising portions contract, the first fallen portions are drawn toward each other, and the waist edge side of the first rising portions rises toward the crotch side. On the other hand, in the side three-dimensional gathers, as the side rising portions contract, the front and rear side fallen portions are drawn toward each other, and the side rising portions rise. Here, the region having the first waist three-dimensional gathers is between the side fallen portions. Therefore, the action of the side three-dimensional gathers drawing the front and rear side fallen portions toward each other also has the action of drawing the first portion of the first waist three-dimensional gathers toward the waist root portion. In addition, the area where the contraction directions of the side rise-up portions and the first rise-up portions intersect, that is, the front and rear side fallen portions having the first waist three-dimensional gathers, are affected by both contractions and are raised toward the wearer's skin.
As a result, the first rising portion of the first waist three-dimensional gather is a portion where a gap is likely to occur against the wearer's skin, and the rising state changes characteristically depending on the size of the gap. That is, while the gap is small, the tip of the first rising portion of the first waist three-dimensional gather faces the waist edge side, the rising angle is small, and the contact is made by a surface. That is, when the risk of leakage is low, a fit with excellent wearing comfort is ensured. On the other hand, when the gap becomes large, the tip side of the first rising portion of the first waist three-dimensional gather rises high, and when the tightening around the waist becomes particularly loose, the middle part in the width direction curls toward the crotch side, or rises high to a state close to curling without curling. That is, when the risk of leakage is high, the state changes to one with better leak prevention. Such a change in the first waist three-dimensional gather is unprecedented, and is particularly effective against back leakage and front leakage caused by loosening of the wearing state over time (for example, due to meal timing, etc.). Therefore, the combination of such a first waist three-dimensional gather and an absorbent layer further enhances the leak prevention effect.
In addition, the first waist three-dimensional gathers in this embodiment rise in the opposite direction to the second waist three-dimensional gathers, and since the two have fundamentally different blocking functions, the leakage prevention properties are superior to those of a case in which the same rising portion is simply provided twice.

The present invention provides the following advantages: Improved prevention of rear or front leakage from connected disposable wearable articles.

1 to 6 show a tape-type disposable diaper as an example of a connected disposable wearable article. Note that, for the parts of the hot melt adhesive that are to be bonded, the plan view shows a diagonal line pattern and a dot pattern, and the cross-sectional view shows a dot pattern, where necessary for explanation. The hot melt adhesive can be applied by known methods such as slot coating, continuous line or dotted line bead coating, spiral or Z-shaped spray coating, or pattern coating (transfer of hot melt adhesive using a letterpress method). Alternatively or in addition to this, the hot melt adhesive can be applied to the outer periphery of the elastic member at the fixing portion of the elastic member to fix the elastic member to the adjacent member. As the hot melt adhesive, for example, EVA-based, adhesive rubber-based (elastomer-based), olefin-based, polyester/polyamide-based, and other types are available, but there are no particular limitations on the types that can be used. As a joining means for joining the respective components, material welding means such as heat sealing and ultrasonic sealing can also be used.

This tape-type disposable diaper has a crotch portion including the center LC in the front-to-rear direction LD, a ventral portion F extending forward from the center LC in the front-to-rear direction LD, and a dorsal portion B extending rearward from the center LC in the front-to-rear direction LD. This tape-type disposable diaper also has an absorbent body 3 built into an area including the crotch portion, a liquid-permeable top sheet 2 covering the front side of the absorbent body 3, a liquid-impermeable sheet 1 covering the back side of the absorbent body 3, and an exterior nonwoven fabric 12 covering the back side of the liquid-impermeable sheet 1 and constituting the outer surface of the product.

The materials and features of each part are explained below.

(Absorber)
The absorbent body 3 has a basic structure having a single layer or multiple layers of fiber assembly layers made of pulp fiber stacks, filament aggregates such as cellulose acetate, or nonwoven fabric. The absorbent body 3 can have a particulate or other superabsorbent polymer mixed in the fiber assembly layer, fixed in the fiber assembly layer or on the surface of the fiber assembly layer, or interposed between the fiber assembly layers in the form of layers. The absorbent body 3 can be wrapped in a wrapping sheet such as crepe paper (not shown) as necessary. The shape of the absorbent body 3 can be appropriately determined, but as shown in the figure, an hourglass shape (constricted shape) in which the width of the middle part in the front-to-back direction LD including the crotch part is narrower than both the front and back sides, as well as a shape extending from the front side to the rear side of the crotch part, such as a rectangle, is preferable. The fiber basis weight of the absorbent body 3 can be about 100 to 500 g/m ² , and the thickness can be about 1 to 15 mm. The basis weight of the superabsorbent polymer in the absorbent body 3 can be about 0 to 300 g/m ² .

(Liquid-impermeable sheet)
The liquid-impermeable sheet 1 prevents excrement from seeping out to the back surface. In addition to plastic films such as polyethylene films, sheets that are moisture-permeable without impairing water-proofing properties can also be used as the liquid-impermeable sheet 1. This water-proof/moisture-permeable sheet can be 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.

It is desirable for the liquid-impermeable sheet 1 to extend over the same or a wider area than the absorbent 3 in the front-rear direction LD and width direction WD, but if necessary, for example, when other water-blocking means are present, it may be structured so that it does not cover the ends of the absorbent 3 in the front-rear direction LD and width direction WD.

To give the outer surface of the diaper a cloth-like appearance and feel, the entire back surface of the liquid-impermeable sheet 1 can be covered with an exterior nonwoven fabric 12. The exterior nonwoven fabric 12 can also be omitted, in which case the liquid-impermeable sheet 1 forms the outer surface of the product.

(Top sheet)
The top sheet 2 is liquid permeable, and may be, for example, a perforated or non-perforated nonwoven fabric, a perforated plastic sheet, or the like.

The top sheet 2 extends from the front to the rear of the product in the front-to-back direction LD, and extends laterally beyond the absorbent body 3 in the width direction WD. However, appropriate modifications can be made as necessary, such as making the width of the top sheet 2 shorter than the overall width of the absorbent body 3, for example, when the starting point of the side three-dimensional gathers 4 described below is located closer to the center in the width direction WD than the side edges of the absorbent body 3.

(Side flap)
The illustrated tape-type disposable diaper has a pair of side flaps SF that do not include the absorbent body 3 and extend laterally from the absorbent body 3. The side flaps SF may be made of a material (such as the exterior nonwoven fabric 12) that is continuous with the portion that includes the absorbent body 3, as in the illustrated example, or may be formed by attaching other materials.

(Flat gathers)
In the middle of the side flaps SF in the front-rear direction LD, elongated leg elastic members 7 are fixed in a stretched state in the front-rear direction LD between the liquid impermeable sheet 1 and the exterior nonwoven fabric 12 by a hot melt adhesive or the like, and the side flaps SF are formed with so-called flat gathers by contraction of the leg elastic members 7. The flat gathers allow the sides of the diaper to elastically expand and contract to fit around the legs. The leg elastic members 7 may be curved to fit around the legs.

The number of leg elastic members 7 on each side can be determined as appropriate, but 1 to 10, more preferably 3 to 8, is appropriate. If multiple members are used, the spacing between them is preferably 2 to 15 mm, and especially 6 to 10 mm. The leg elastic members 7 can be made of commonly used materials such as styrene rubber, olefin rubber, urethane rubber, ester rubber, polyurethane, polyethylene, polystyrene, styrene butadiene, silicone, and polyester, formed into threads, strings, or strips, and the thickness is preferably about 500 to 1500 dtex, and in the case of natural rubber, about 0.1 to 3 mm, and especially about 0.5 to 3 mm. The stretch rate of each leg elastic member 7 when fixed is preferably about 150 to 250%.

(Wing part)
In this tape-type disposable diaper, the back portion B has wing portions extending outward in the width direction WD from the crotch portion. Similarly, the ventral portion F also has wing portions extending outward in the width direction WD from the crotch portion. These wing portions may be formed of a separate material from the other portions. However, in the structure having side flaps SF as shown in the figure, it is preferable to form concave leg-surrounding edges Le extending from the side edges of the crotch portion to the lower edges of the wing portions by cutting the middle of the sides of the side flaps SF in the front-to-rear direction LD, as this facilitates manufacturing.

(Connecting tape)
Connecting tapes 5 are attached to both side portions of the back portion B (wing portions of the side flaps SF in the illustrated example) so as to protrude from the side edges, and a target sheet 6 is attached along the width direction WD to the surface of the waist circumference portion of the abdominal portion F. When putting the diaper on the body, with the diaper 100 placed on the body, the connecting tapes 5 on both sides are wrapped around from each side of the waist to the outer abdominal surface and fastened to the target sheet 6. The target sheet 6 can be omitted, in which case the connecting tapes 5 are fastened directly to the outer surface of the diaper (exterior nonwoven fabric 12 in the illustrated example).

As shown in FIG. 3, the connecting tape 5 has a fixing portion 5f fixed between the sheets in the side flap SF of the back side portion B by means of a hot melt adhesive or the like, and a protruding portion 5e protruding outward in the width direction WD from between the sheets at the side edge of the side flap SF, and this protruding portion 5e has a tip portion 5p and a main portion 5b on the base end side of the tip portion 5p. On the inner surface of the tip portion 5p of the connecting tape 5, a hook material (male material of a hook-and-loop fastener) of a mechanical fastener having a large number of hook-shaped projections on its surface is attached as a connecting portion 9 for connecting to the target sheet 6. In addition, a target sheet 6 having a surface to which the hook-shaped projections are detachably attached (female material of a mechanical fastener (hook-and-loop fastener)) is attached to the outer surface of the abdominal portion F. The material of the outer surface of the diaper itself can be used instead of the target sheet 6, or an adhesive layer can be used as the connecting portion 9 instead of the hook material, and a resin tape with a smooth surface that is highly adhesive can be used as the target sheet 6.

As shown in FIG. 1, the connecting tape 5 has perforations 10 that run along the width direction WD from the outer edge in the width direction WD at the middle of the front-rear direction LD to inside the main body 5b. By cutting the perforations 10, the connecting tape 5 can be separated into an upper and lower section, each of which has a fixing section, a main body, a tip section, and a connecting section 9, as shown in FIG. 11. Instead of the perforations 10, the connecting tape 5 may be separated in advance by cutting or the like. Such a connecting tape 5 can be detachably connected to the target sheet 6 of the abdominal section F with the upper and lower sections crossed. Of course, the present invention is not limited to this type of two-section, and can also be applied to other known connecting tapes, such as a type that is not divided into two sections.

(3D gathers on the sides)
As shown in Figures 1, 4 and 5, in order to block excrement moving laterally along the top sheet 2 and prevent so-called lateral leakage, three-dimensional side gathers 4 are provided on both sides of the surface in the width direction WD, rising from the surface along blocking positions extending in the front-to-rear direction.

More specifically, the three-dimensional side gathers 4 have a side root portion 4x fixed to an area including the side flap SF, a side main portion 4c extending from the side root portion 4x, a side front fallen portion 4b and a side rear fallen portion 4e formed by fixing the front end and rear end of the side main portion 4c in a fallen state, and a side rise portion 4f formed by leaving the portion between the side front fallen portion 4b and the side rear fallen portion 4e of the side main portion 4c unfixed. In addition, a side three-dimensional elastic member 4G is attached to at least the tip of the side rise portion 4f.

Each part of the side three-dimensional gather 4 in the illustrated example is formed by a side three-dimensional sheet 4s, and this side three-dimensional sheet 4s is folded in half at the tip of the side main part 4c (the end opposite the side root part 4x side), so that the range including the free part has a two-layer structure. The side three-dimensional elastic member 4G is sandwiched between the layers of this two-layer structure. The side three-dimensional elastic member 4G can be provided only on the side rising part 4f, but it is preferable to fix it from the rear end of the side front falling part 4b to the front end of the side rear falling part 4e as in the illustrated example, because the contraction force of the side three-dimensional elastic member 4G acts not only over the entire side rising part 4f but also to the ends of the side front falling part 4b and the side rear falling part 4e.

The inner surface of the side three-dimensional sheet 4s has a joining start point in the width direction WD on the side of the top sheet 2, and the portion outside the joining start point in the width direction WD is joined with a hot melt adhesive or the like to each side flap SF, that is, in the illustrated example, to the side of the liquid-impermeable sheet 1 and the side of the exterior nonwoven fabric 12 located outside the side in the width direction WD. Note that the dotted pattern in the plan view indicates the attached portion of the side three-dimensional gathers 4.

The inside of the joining start point of the side three-dimensional gathers 4 in the width direction WD is fixed to the top sheet 2 at both ends in the front-to-back direction, but the side rise-up portion 4f between them is an unfixed free portion. Therefore, the side rise-up portion 4f rises while contracting in the front-to-back direction due to the contraction force of the side three-dimensional elastic member 4G, and becomes stretchable in the front-to-back direction, so that it fits closely to the body surface. Also, as the side rise-up portion 4f contracts in the front-to-back direction due to the contraction force of the side three-dimensional elastic member 4G, the portions having the side front collapsed portion 4b and the side rear collapsed portion 4e deform so as to approach each other.

Although not shown, as is well known, the main side portion 4c of the side three-dimensional gathers 4 can be folded in half to have a base end portion extending from the outer portion in the width direction WD to the inside of the width direction WD and a tip end portion that is folded back from the edge on the center side of the base end portion in the width direction WD toward the body and extends to the outside of the width direction WD, and both ends of the main side portion 4c in the front-to-rear direction LD can be fixed to form a fallen portion.

The type of the side three-dimensional sheet 4s is not particularly limited, but in most cases, a water-repellent material is used to ensure liquid blocking properties. In particular, nonwoven fabrics having meltblown layers between spunbond layers (SMS nonwoven fabric, SMMS nonwoven fabric, SSMS nonwoven fabric, SSMMS nonwoven fabric) are suitable because they can achieve both softness and liquid blocking properties. The nonwoven fabric can be used in a single layer or multiple layers stacked together. In the latter case, it is preferable to bond the nonwoven fabrics together with a hot melt adhesive or the like.

The three-dimensional elastic side members 4G can be made of commonly used materials such as natural or synthetic rubber formed into threads, strings, or strips, specifically styrene rubber, olefin rubber, urethane rubber, ester rubber, polyurethane, polyethylene, polystyrene, styrene butadiene, silicone, and polyester. As shown in Figures 1 and 2, the three-dimensional elastic side members 4G can be provided spaced apart from each other, or one at a time. The stretch rate of the three-dimensional elastic side members 4G in the deployed state can be determined as appropriate, but for example, in the case of spandex rubber threads with a thickness of about 420 to 1120 dtex, it can be about 230 to 270%.

(end flap)
This tape-type disposable diaper has a pair of end flaps EF that do not include the absorbent body 3 and extend to the front and rear sides of the absorbent body 3, respectively. The constituent materials of the end flaps EF vary depending on the structure of the diaper. In the illustrated example, the end flaps EF are formed by the liquid-impermeable sheet 1, the exterior nonwoven fabric 12, the top sheet 2, and the side three-dimensional sheet 4s that are laminated and extend to the front and rear sides of the absorbent body 3 and joined together, but are not limited to this. The end flaps EF may be formed by adding a sheet dedicated to forming the end flaps EF to the front or rear side of the absorbent body 3.

Normally, the dimension of the end flap EF in the front-to-back direction LD can be approximately 1-10% of the dimension of the entire diaper in the front-to-back direction LD.

(3D gathers at waist)
1, 5, 8 and 9, the rear end of the illustrated disposable diaper is provided with a first waist three-dimensional gather 20 having a first rising portion 25 rising from the surface along a first cut-off position along the width direction WD, and a second waist three-dimensional gather 30 having a second rising portion 35 rising from the surface along a second cut-off position along the width direction WD, which is away from the first cut-off position toward the crotch side. At least a part of the region from the first rising portion 25 to the second rising portion 35 has an absorbent layer 40 containing a highly absorbent polymer, so that excreted liquid that reaches the surface between the first rising portion 25 and the second rising portion 35 can be supplied to the absorbent layer 40.

9 and 10, the disposable diaper exhibits a two-stage leakage prevention function in which the second waist three-dimensional gathers 30 basically prevent the movement of excrement, and the first waist three-dimensional gathers 20 prevents excrement that has somehow passed over the second waist three-dimensional gathers 30 from leaking. Furthermore, the disposable diaper not only blocks excrement that has passed over the second waist three-dimensional gathers 30 with the first waist three-dimensional gathers 20, but also absorbs and holds the blocked excrement with the absorbent layer 40 provided at the blocking position (between the first rising portion and the second rising portion 35). This prevents excrement blocked by the first waist three-dimensional gathers 20 from causing skin trouble, or excrement that has been blocked ends up leaking out when a gap is formed between the first waist three-dimensional gathers 20 and the skin.

The absorbent layer 40 is not particularly limited in its position in the front-rear direction LD as long as it is provided in at least a part of the area from the first rise portion 25 to the second rise portion 35, but it is preferable that it is provided to include at least a part (e.g. 50% or more) of the non-rise portion (waist root portion 22 described later in the illustrated example) located between the first rise portion 25 and the second rise portion 35, and more preferably, it is provided to include the entirety. The non-rise portion between the first rise portion 25 and the second rise portion 35 is the part where excrement that has exceeded the second waist three-dimensional gather 30 collects, so by having the absorbent layer 40 in this position, the excrement blocked by the first waist three-dimensional gather 20 can be moved to the absorbent layer 40 more quickly.

Specifically, the first rising portion 25 and the second rising portion 35 in the example shown in Figs. 1 to 8 have a front sheet layer 41 and a back sheet layer 42 that continue to the waist root portion 22 attached to the end flap EF, and an absorbent layer 40 is interposed between these sheet layers 41, 42 at the waist root portion 22. In this way, by interposing the absorbent layer 40 at least in the waist root portion 22, the excreted liquid blocked by the first waist three-dimensional gather 20 can be quickly absorbed by the absorbent layer 40 arranged near the surface. The front sheet layer 41 and the back sheet layer 42 can be formed by folding a sheet in half and bonding them together, as in the example shown in Figs. 6 and 7, or by overlapping and bonding separate sheets together. The front sheet layer 41 and the back sheet layer 42 are preferably bonded together via a hot melt adhesive 43.

The absorbent layer 40 may contain hydrophilic fibers such as pulp as long as it contains a superabsorbent polymer, but if it is made only of a superabsorbent polymer as in the illustrated example, it is possible to prevent the deterioration of the wearing comfort due to an increase in thickness. As the superabsorbent polymer, in addition to the particulate type that is commonly used as a material contained in the absorbent body 3, fibrous type, sheet type, etc. can be used without any particular limitation. It is desirable to fix the particulate or other superabsorbent polymer to at least one of the sheet layers 41, 42 on the front and back sides via a hot melt adhesive as shown in FIG. 8.

When the front sheet layer 41 is provided on the front side of the absorbent layer 40, the material is not particularly limited as long as the excreted liquid that reaches the surface between the first rising portion 25 and the second rising portion 35 can be supplied to the absorbent layer 40. For example, the front sheet layer 41 can be made of a nonwoven fabric with or without holes, a plastic sheet with holes, or the like, as in the top sheet 2. In particular, since the sheet forming the first waist three-dimensional gather 20 or the second waist three-dimensional gather 30 is almost always not permeable to liquid, such as a water-repellent nonwoven fabric, when this is the front sheet layer 41 as in the example shown in FIG. 8, it is preferable that the front sheet layer 41 has through holes 45 that penetrate from the front to the back in order to promote the supply of excreted liquid to the absorbent layer 40. It is preferable to provide a plurality of through holes 45 at intervals. In addition to arranging them in a row at intervals in the width direction WD as in the illustrated example, they can also be arranged in multiple rows at intervals in the front-to-back direction LD, or in an appropriate pattern such as a staggered pattern.

The front sheet layer 41 has such through holes 45, so that the excreted liquid can easily reach the absorbent layer 40 through the through holes 45. However, if the absorbent layer 40 is located at a position overlapping the through holes 45, the absorbent layer 40 that has absorbed the excreted liquid may come into contact with the skin, which may cause skin trouble. Therefore, as shown in FIG. 6, it is preferable that a plurality of through holes 45 are formed at intervals, and the absorbent layer 40 is provided only between adjacent through holes 45. This not only makes it easier for the excreted liquid to reach the absorbent layer 40 through the through holes 45, but also makes it difficult for the absorbent layer 40 that has absorbed the excreted liquid to come into contact with the skin because it is covered with the front sheet layer 41. In addition, as shown in the schematic diagrams of the states before and after absorption in FIG. 12 (a) and (b), when the highly absorbent polymer of the absorbent layer 40 absorbs the excreted liquid and expands, the front sheet layer 41 is lifted, and the excreted matter is easily introduced into the absorbent layer 40 through the through holes 45. In this case, the front sheet layer 41 and its opposing back surface may be entirely bonded, but it is preferable to leave the annular portion 44 around the periphery of the through hole 45 unbonded, because this allows the opening to expand when the front sheet layer 41 is lifted as the absorbent layer 40 expands.

As shown in FIG. 7, it is also preferable to have an opening and closing flap 46 that extends from the periphery of the through hole 45 to cover the through hole 45. By having such an opening and closing flap 46, as shown in FIG. 11, the absorbent layer 40 that has absorbed the excreted liquid is covered by the opening and closing flap 46, making it less likely to come into contact with the skin. Therefore, the absorbent layer 40 can be placed in a position that overlaps the through hole 45. In the illustrated example, the opening and closing flap 46 is formed by forming a cut in the periphery of the part of the front sheet layer 41 that will become the through hole 45, excluding the part that will become the root 46b of the opening and closing flap 46, but the opening and closing flap 46 may be attached separately.

The orientation of the opening and closing flap 46 is not particularly limited, but if the base 46b of the opening and closing flap 46 is located on the waist side of the through hole 45 and shrinkage wrinkles are formed in the area including the base of the opening and closing flap 46 due to the shrinkage of the first three-dimensional elastic member 21 described below, as shown in Figure 11, the opening and closing flap 46 will be slightly raised to form a gap, making it easier for excreted liquid to reach the absorbent layer 40 through the through hole 45, which is preferable.

The structure of the first waist three-dimensional gather 20 is not particularly limited, but the one shown in Fig. 1 to Fig. 8 is preferable. That is, in the example shown in the figure, the first waist three-dimensional gather 20 is provided, which rises from the surface along the first blocking position between the side rear fallen parts 4e. More specifically, as shown in Fig. 5 and Fig. 8, the first waist three-dimensional gather 20 has a waist root part 22 attached along the first blocking position of the end flap EF, a first part 23 extending from the waist root part 22 to the waist edge side, a first fallen part 24 formed by fixing both ends of the first part 23 in the width direction WD in a fallen state, and a first rising part 25 formed by not fixing the part between the first fallen parts 24 in the first part 23. In addition, a first three-dimensional elastic member 21 is attached to at least the tip part (the end part on the waist edge side) of the first rising part 25. As a result, at least the tip of the first raised portion 25 is contracted in the width direction WD together with the first three-dimensional elastic member 21, and is also capable of stretching in the width direction WD.

The first waist three-dimensional gather 20 in the illustrated example is formed by a waist three-dimensional sheet 26, and has a two-layer structure formed by folding back this waist three-dimensional sheet 26. The first three-dimensional elastic member 21 is sandwiched between the layers of this two-layer structure and fixed with a hot melt adhesive or the like. The first three-dimensional elastic member 21 can be provided only on the first rising portion 25, but it is preferable to fix it from one first falling portion 24 to the other first falling portion 24 as in the illustrated example, because the contractile force of the first three-dimensional elastic member 21 acts not only over the entire first rising portion 25 but also up to the first falling portion 24.

The inner surface of the waist three-dimensional sheet 26 in the illustrated example has a joining start point in the front-to-back direction LD on the end flap EF, and the part behind this joining start point is joined to the inner surface of the end flap EF, that is, in the illustrated example, to the surface of the top sheet 2 with a hot melt adhesive or the like. Note that the part where the waist three-dimensional sheet 26 is attached to the top sheet 2 is shown by a diagonal line going diagonally downward to the right in Figures 1 and 5(a).

The waist edge side of the joining start point of the first waist three-dimensional gather 20 has a first fallen portion 24 fixed to the top sheet 2 at both ends in the width direction WD, but the first rise portion 25 between them is an unfixed free portion. Therefore, the first rise portion 25 rises while contracting in the width direction WD due to the contraction force of the first three-dimensional elastic member 21, and becomes stretchable in the width direction WD, so that it fits closely to the body surface. Also, as the first rise portion 25 contracts in the width direction WD due to the contraction force of the first three-dimensional elastic member 21, the portion having one first fallen portion 24 and the portion having the other first fallen portion 24 deform so as to approach each other.

On the other hand, as the side rising portion 4f contracts, the side front falling portion 4b and the side rear falling portion 4e are drawn toward each other, and the side rising portion 4f rises. Here, the area having the first waist three-dimensional gather 20 is located between the side rear falling portions 4e. Therefore, the action of the side three-dimensional gather 4 drawing the side front falling portion and the side rear falling portion 4e toward each other (see the arrow in FIG. 11) also has the action of drawing the first portion 23 of the first waist three-dimensional gather 20 toward the waist root portion 22 (see the arrow in FIG. 11). In addition, the area where the contraction of the side rising portion 4f and the contraction of the first rising portion 25 intersect, that is, the side front falling portion 4b or the side rear falling portion 4e that has the first waist three-dimensional gather 20, is influenced by both contractions and rises toward the wearer's skin.

As a result, the first rising portion 25 of the first waist three-dimensional gather 20 is a portion where a gap is likely to occur against the wearer's skin, and as shown in Figs. 9 to 10(a), the rising state changes characteristically depending on the size of the gap between the inner surface of the product and the wearer's skin surface BS. That is, while the gap is small, as shown in Fig. 9(a), the tip of the first rising portion 25 of the first waist three-dimensional gather 20 faces the waist edge side, the rising angle is small, and the contact is made by surface. In other words, when the risk of leakage is low, a fit with excellent wearing comfort is ensured. On the other hand, when the gap becomes large, as shown in Fig. 9(b), the tip side of the first rising portion 25 of the first waist three-dimensional gather 20 rises high, and when the tightening around the waist becomes particularly loose, as shown in Figs. 10(a) and 11, the tip side of the middle part in the width direction WD curls back toward the crotch side (or rises high to a state close to curling, although it does not curl back). In other words, when the risk of leakage is high, the state changes to one with better leak prevention. This type of change in the first waist three-dimensional gathers 20 is unprecedented and is particularly effective in preventing rear and front leakage caused by loosening of the garment over time (e.g., due to meal timing, etc.).

The first collapsed portion 24 in the illustrated example is a portion sandwiched between the top sheet 2 and the side three-dimensional sheet 4s in the side rear collapsed portion 4e and joined to both sheets by a joining means such as a hot melt adhesive, but it may be provided on the side three-dimensional sheet 4s in the side rear collapsed portion 4e. In other words, although not shown, the first waist three-dimensional gather 20 may be provided on the side three-dimensional gather 4.

The type of waist three-dimensional sheet 26 is not particularly limited, but in most cases, a water-repellent material is used to ensure liquid blocking properties. In particular, nonwoven fabrics having meltblown layers between spunbond layers (SMS nonwoven fabric, SMMS nonwoven fabric, SSMS nonwoven fabric, SSMMS nonwoven fabric) are suitable because they can achieve both softness and liquid blocking properties. The nonwoven fabric can be used in a single layer or multiple layers stacked together. In the latter case, it is preferable to bond the nonwoven fabrics together with a hot melt adhesive or the like.

The first three-dimensional elastic member 21 can be made of commonly used materials such as natural or synthetic rubber formed into threads, strings, strips, etc., specifically styrene-based rubber, olefin-based rubber, urethane-based rubber, ester-based rubber, polyurethane, polyethylene, polystyrene, styrene butadiene, silicone, polyester, etc. The first three-dimensional elastic member 21 can be provided in a number of intervals as in the illustrated example, or it can be provided with only one. The elongation rate of the first three-dimensional elastic member 21 in the deployed state can be determined as appropriate, but for example, in the case of spandex thread rubber with a thickness of about 600 to 1300 dtex, it can be about 130 to 250%, particularly about 160 to 200%.

When multiple first three-dimensional elastic members 21 are provided at intervals in the front-to-rear direction LD, the stretch rate of all of them may be the same, but some or all of them may have different stretch rates. For example, it is preferable that the stretch rate of the stretch rate in the expanded state is lower closer to the waist edge, because this makes the tip side of the first raised portion 25 more likely to curl.

The position of the first three-dimensional elastic member 21 can be determined as appropriate, but it is preferable that the first three-dimensional elastic member 21 located at the tip (closest to the waist edge) is located about 2 to 40 mm away from the rear edge of the waist root portion 22, as this makes it easier for the tip side of the first raised portion 25 to curl back. For the same reason, it is preferable that the first three-dimensional elastic member 21 located at the tip (closest to the waist edge) is located away from the front edge of the end flap EF.

In tape-type disposable diapers, gaps are likely to form between the area located closer to the waist edge than the connecting part 9 (meaning the one closest to the waist edge if there are multiple connecting parts in the front-to-rear direction LD) and the skin. Therefore, in the unfolded state, it is preferable for the first waist three-dimensional gather 20 to have a first three-dimensional elastic member 21 located closer to the waist edge than the connecting part 9, as this allows the above-mentioned deformation of the first waist three-dimensional gather 20 to be effectively expressed.

The first portion 23 of the first waist three-dimensional gather 20 can also extend from the waist base portion 22 toward the crotch area, similar to the second portion 33 of the second waist three-dimensional gather 30 described below.

The structure of the second waist three-dimensional gathers 30 is not particularly limited, but the one shown in Fig. 1 to Fig. 8 is preferable. That is, the second waist three-dimensional gathers 30 shown in the figure preferably have a second part 33 extending from the waist root part 22 toward the crotch side, a second fallen part 34 formed by fixing both ends of the second part 33 in the width direction WD in a fallen state, a second rise part 35 formed by leaving the part of the second part 33 between the second fallen parts 34 unfixed, and a second three-dimensional elastic member 31 attached to at least the tip of the second rise part 35. This provides a two-stage leakage prevention function in which the second rise part 35 basically prevents the movement of excrement, and the first rise part 25 prevents leakage of excrement that has somehow passed over it. Here, since the first rising portion 25 has a fundamentally different blocking function from the second rising portion 35 as described above, it goes without saying that the leak prevention is superior to the case where two identical rising portions are simply provided.

In the example shown in Figure 8, the waist root portion 22 of the second waist three-dimensional gather 30 is common to the first waist three-dimensional gather 20, but it can also be provided separately, as in the example shown in Figure 10 (b).

In the illustrated example, the second portion 33 of the second waist three-dimensional gather 30 is located in the range in the front-rear direction LD that includes the side rising portion 4f of the side three-dimensional gather 4, but part or all of the second portion 33 may be located in the range in the front-rear direction LD that includes the side rear fallen portion 4e. In the former case, the second fallen portion 34 is located in the area that includes the side root portion 4x, but in the latter case, it may be located in the area that includes the side rear fallen portion 4e.

In addition, when the second portion 33 of the second waist three-dimensional gather 30 is located in the range in the front-to-back direction LD that includes the side rise portion 4f of the side three-dimensional gather 4, it is preferable that the second rise portion 35 and the side rise portion 4f are not joined at the overlapping portion, but they may be joined.

＜Other＞
In the above example, the first waist three-dimensional gathers 20, the second waist three-dimensional gathers 30 and the absorbent layer 40 are provided only in the back portion B, but instead of or in addition to this, the first waist three-dimensional gathers 20, the second waist three-dimensional gathers 30 and the absorbent layer 40 can also be provided in the abdominal portion F.

As the nonwoven fabric in the above description, known nonwoven fabrics can be used appropriately depending on the part and purpose. The constituent fibers of the nonwoven fabric can be selected without particular limitation, for example, synthetic fibers such as olefins such as polyethylene or polypropylene, polyesters, polyamides, etc. (including single-component fibers as well as composite fibers such as core-sheath fibers), regenerated fibers such as rayon or cupra, natural fibers such as cotton, etc., and these can also be used in combination. In order to increase the flexibility of the nonwoven fabric, it is preferable to use crimped fibers as the constituent fibers. In addition, the constituent fibers of the nonwoven fabric may be hydrophilic fibers (including those made hydrophilic by a hydrophilizing agent), hydrophobic fibers, or water-repellent fibers (including water-repellent fibers made water-repellent by a water-repellent agent). Nonwoven fabrics are generally classified into staple fiber nonwoven fabrics, long fiber nonwoven fabrics, spunbond nonwoven fabrics, meltblown nonwoven fabrics, spunlace nonwoven fabrics, thermal bond (air-through) nonwoven fabrics, needle punch nonwoven fabrics, point bond nonwoven fabrics, laminated nonwoven fabrics (SMS nonwoven fabrics with a meltblown layer sandwiched between spunbond layers, SMMS nonwoven fabrics, etc.) depending on the fiber length, sheet formation method, fiber bonding method, and laminated structure, but any of these nonwoven fabrics can be used.

<Explanation of terms used in the specification>
As used herein, the following terms have the following meanings unless otherwise specified in the specification.

The "front-rear direction" refers to the direction indicated by the symbol LD in the figure (longitudinal direction), and the "width direction" refers to the direction indicated by the symbol WD in the figure (left-right direction), with the front-rear direction and the width direction being perpendicular to each other.

"MD direction" and "CD direction" refer to the flow direction (MD direction) in the manufacturing equipment and the horizontal direction (CD direction) perpendicular to it, and depending on the part of the product, one of them may be the front-to-back direction and the other the width direction. The MD direction of a nonwoven fabric is the direction of fiber orientation of the nonwoven fabric. Fiber orientation is the direction in 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 using zero-distance tensile strength in TAPPI standard method T481, or a simple measurement method that determines the fiber orientation direction from the tensile strength ratio in the front-to-back direction and the width direction.

- "Front side" means the side closest to the wearer's skin when worn, and "back side" means the side farthest from the wearer's skin when worn.

- "Front side" means the side of the component that is closest to the wearer's skin when worn, and "back side" means the side of the component that is farthest from the wearer's skin when worn.

"Elongation rate" refers to the value when the natural length is 100%. For example, an elongation rate of 200% is equivalent to an elongation ratio of 2 times.

- "Gel strength" is measured as follows. 1.0 g of superabsorbent polymer is added to 49.0 g of artificial urine (a mixture of urea: 2 wt%, sodium chloride: 0.8 wt%, calcium chloride dihydrate: 0.03 wt%, magnesium sulfate heptahydrate: 0.08 wt%, and ion-exchanged water: 97.09 wt%) and stirred with a stirrer. The resulting gel is left in a thermo-hygrostat at 40°C x 60% RH for 3 hours, then returned to room temperature, and the gel strength is measured with a curd meter (I.techno Engineering: Curdmeter-MAX ME-500).

・"Basis weight" is measured as follows. After pre-drying the sample or test piece, leave it in a test room or device under standard conditions (test location: temperature 23±1°C, relative humidity 50±2%) until it reaches a constant weight. Pre-drying refers to bringing the sample or test piece to a constant weight in an environment at a temperature of 100°C. Note that pre-drying is not necessary for fibers with an official moisture regain of 0.0%. Using a sample collection template (100mm x 100mm), cut out a sample measuring 100mm x 100mm from the test piece that has reached a constant weight. Measure the weight of the sample and multiply it by 100 to calculate the weight per square meter, which is the basis weight.

"Thickness" is automatically measured using an automatic thickness measuring device (KES-G5 Handy Compression Measurement Program) under conditions of a load of 0.098 N/ ^cm2 and a pressurized area of 2 ^cm2 . The thickness of a perforated nonwoven fabric is measured in the area excluding the holes and the protruding parts around them.

- Water absorption is measured according to JIS K7223-1996 "Water absorption test method for superabsorbent resins."

The water absorption rate is the "time to the end point" when 2 g of superabsorbent polymer and 50 g of saline are used to perform the "water absorption rate test method for superabsorbent polymers" according to JIS K7224-1996.

The fiber orientation direction of a nonwoven fabric is the direction in which the fibers of the nonwoven fabric run, and can be determined, for example, by a measurement method based on the fiber orientation test method using zero-distance tensile strength in TAPPI standard method T481, or a simplified measurement method that determines the fiber orientation direction from the tensile strength ratio in the front-to-rear and width directions.

- "Expanded state" means a flat, unfolded state without contraction (including any contraction, such as contraction due to elastic members) or sagging.

- Unless otherwise specified, the dimensions of each part refer to the dimensions in the unfolded state, not the natural length.

-If no specification is given regarding the environmental conditions for a test or measurement, the test or measurement shall be performed in a test room or equipment under standard conditions (the test location shall be a temperature of 23±1°C and a relative humidity of 50±2%).
