Description

  The present invention relates to a connection type disposable wearing article called a tape type disposable diaper or the like.

  A general connection-type disposable wearing article has a crotch portion including the center in the front-rear direction, a ventral portion extending forward from the center in the front-rear direction, and a back portion extending rearward from the center in the front-rear direction. Has a wing portion extending to the left and right sides in the width direction from the crotch portion. A connection tape (connection tab) having a connection portion detachably connected to the outer surface of the abdominal portion is attached to the wing portion. In use, the wing portion is turned from both sides of the waist to the outer surface of the abdominal portion, and the connecting portion of the connecting tape is connected to the outer surface of the abdominal portion. Such a connection type disposable wearing article is used not only for infants but also for nursing care (adult use) (for example, see Patent Document 1).

  Conventionally, as a connecting tape, a base end portion fixed to a wing portion, a main body portion extending from the base end portion, and an abdominal portion provided in the middle in the width direction of the main body portion are detachably connected. It generally has a connecting portion and a non-connecting portion provided between the connecting portion and the base end portion and not connected to the abdominal portion.

  Such connected disposable wearing articles are used for infants and infants and are widely used for nursing care (adult use), but have a problem that the waist circumference and the leg circumference are easily loosened.

  As a solution to this problem, there has been proposed a connection type disposable wearing article in which the connection tape can be divided into upper and lower stages by perforations (for example, see Patent Document 1). This connection-type disposable wearing article is connected while pulling the first connection tape on the waist side diagonally downward and firmly tightening around the waist, and connecting the second connection tape on the leg circumference side diagonally upward. By doing so, the circumference of the leg can be firmly tightened, and a fitted state with excellent fit can be obtained.

  However, in the device described in Patent Document 1, the portion divided into two upper and lower sections is limited to the connecting tape, so the first connecting tape on the waist side is directed obliquely downward and the second connecting tape on the leg circumference is directed obliquely upward. When each is connected, large wrinkles are attached to the wing portion, and the appearance is deteriorated.

  Further, in the device described in Patent Literature 1, since the portion divided into upper and lower two stages is limited to the connecting tape, in order to take advantage of the advantage, it is necessary to secure a certain length in the width direction of the connecting tape. . However, since the connecting tape is made of a relatively hard material in order to secure sufficient strength and to facilitate cutting during manufacturing, when the width of the connecting tape becomes longer, the connecting tape becomes longer. There is also a problem that the hardness of the body greatly affects the feeling of wearing.

JP 2005-160506 A

  Therefore, a main problem of the present invention is to provide a connection type disposable wearing article which can obtain a tightly fitted mounting state by a two-stage connection tape and reduce wrinkles formed on a wing portion, and the like. It is in.

The connection type disposable wearing article which solved the above-mentioned subject is as follows.
<First aspect>
A crotch portion including the center in the front-rear direction, a ventral portion extending forward from the center in the front-rear direction, and a back portion extending rearward from the center in the front-rear direction,
Having an absorber incorporated in a range including the crotch portion,
The back side portion has a side flap portion extending to the side of the absorber,
The side flap portion of the back portion has a wing portion extending outward in the width direction from the crotch portion,
Attached to the wing portion of the dorsal portion, comprising a connecting tape detachably connected to the abdominal portion,
The connection tape has a base end portion fixed to the wing portion, a main body portion extending from the base end portion, and a connection portion provided to the main body portion and connected to the abdominal portion. ,
In articulated disposable wearing articles,
As the connection tape, a first connection tape provided on the waist side of the wing portion, and a second connection tape provided on the leg circumference side of the wing portion,
The side flap portion includes, at a side edge of the wing portion, a divided perforation extending inward in a width direction from between the first connection tape and the second connection tape, and a width direction of the divided perforation. A finger insertion hole adjacent to the inner end of the
A disposable disposable wearing article characterized in that:

(Effects)
In the present connection type disposable wearing article, insert a finger into the finger insertion hole and move the finger to the side of the divided perforation, or pinch the side of the divided perforation with the finger, and move the divided perforation from the inside in the width direction. By sequentially separating outwardly, at least a portion of the wing portion can be divided into upper and lower stages. Then, the upper part having the first connection tape on the waist side is connected while being pulled obliquely downward, so that the circumference of the waist is firmly tightened, and the lower part having the second connection tape on the leg circumference side is connected while being pulled obliquely upward. By doing so, the circumference of the leg can be securely tightened. Especially, because the wing part which is not divided conventionally is divided into two steps and can be fitted independently according to the circumference of the waist and the circumference of the legs, it is possible to obtain a more tightly fitted state than the conventional one It is.

  And since this connection type disposable wearing article is provided with divided perforations in the side flap portion and divided into upper and lower two steps, the first connection tape on the waist side is directed obliquely downward and the second on the leg circumference side. Even if the connecting tapes are connected diagonally upward, large wrinkles are unlikely to adhere to the wing portions, and the appearance is hardly deteriorated.

  In addition, if a divided perforation is provided on the side flap portion and this divided perforation is separated from the side edge side and divided into two upper and lower stages, when the divided perforation is torn to the inner end, the divided perforation is moved from the inner end to the inner perimeter. There is a possibility that the side flap portion may be further torn to the inner portion (hereinafter, also referred to as excessive tearing). On the other hand, when the finger is inserted into the finger insertion hole as described above and the divided perforations are cut outward from the inside in the width direction, excessive tearing does not occur. Furthermore, since the finger insertion hole is a conspicuous portion, there is also an advantage that there is little possibility that the place where the finger is to be inserted like a slit is lost or the finger cannot be easily inserted.

  The term “finger insertion hole” is formed by punching out a target portion, and has both an anteroposterior dimension and a width dimension in an unfolded state and has an area.

<Second aspect>
The width dimension of the connection tape is 1/7 to 1/2 times the width dimension of a portion of the back portion excluding the connection tape.
The disposable disposable wearing article according to the first aspect.

(Effects)
In the present connection type disposable wearing article, since the side flap portion is divided into upper and lower stages, the width dimension of the connection tape can be reduced. Therefore, in the present connection-type disposable wearing article, it is possible to obtain a tightly fitted mounting state by the upper and lower two-stage connecting tapes, while reducing the influence of the hardness of the connecting tapes on the feeling of wearing.

<Third aspect>
In the divided perforations, the width of the tie portion of the first portion located laterally from the middle in the width direction is wider than the width of the tie portion of the second portion located inward in the width direction than the first portion.
The articulated disposable wearing article according to the first or second aspect.

(Effects)
As in the present embodiment, if the second part of the divided perforation from the beginning of tearing to a certain extent is easily torn, and if the subsequent first part is difficult to tear the divided perforation, the separation of the divided perforation becomes easy to start, so that the wing It becomes easy to divide the part into two upper and lower stages. Further, the divided perforations can be used without being separated, and in such a case, it is unlikely that the divided perforations are unintentionally separated.

<Fourth aspect>
In the finger insertion hole, at least the upper edge and the lower edge of the portion located on the outer side in the width direction extend toward the inner end in the width direction of the divided perforation,
The articulated disposable wearing article according to any one of the first to third aspects.

(Effects)
It is preferable that the finger insertion hole has such a shape, since the moving direction of the finger toward the divided perforation can be easily understood. Further, with the movement of the finger toward the divided perforations, the upper edge and the lower edge are gradually expanded to apply a force for tearing the divided perforations, so that the tearing of the divided perforations can be started smoothly.

<Fifth aspect>
The size of the finger insertion hole in the front-rear direction is 8 to 18 mm, and the size of the finger insertion hole in the width direction is 8 to 18 mm.
The articulated disposable wearing article according to any one of the first to fourth aspects.

(Effects)
Although the size of the finger insertion hole can be determined as appropriate, it is preferable that the size be within the above range, since the index finger can be easily inserted and the trace of the finger insertion hole does not become large after the split perforation is torn.

<Sixth aspect>
An elastic sheet that elastically expands and contracts in the width direction is attached to at least the left and right side flap portions on the back side portion,
The stretch sheet extends to the side more than the finger insertion hole,
The articulated disposable wearing article according to any one of the first to fifth aspects.

(Effects)
With the finger insertion hole, when the divided perforation is used separately, the corner formed from the edge of the finger insertion hole to the divided perforation may flutter and deteriorate the appearance and the feeling of wearing. There is. On the other hand, when the stretchable sheet is extended to the side of the finger insertion hole and the rigidity of the region including the finger insertion hole is increased as described above, after the separation perforation is performed, the divided perforation is cut from the edge of the finger insertion hole. Is preferable because the corners formed in the portion reaching to become difficult to move easily.
In addition, since it is known that the above-mentioned elastic sheet is attached to the back part of the tape-type disposable diaper to improve the fit around the waist, extending the elastic sheet as described above is not possible with the elastic sheet. It is also preferable from the viewpoint of effective use of.

<Seventh aspect>
The stretchable sheet is a non-stretchable region in which the region located on the side than the widthwise inner end of the finger insertion hole does not elastically expand and contract in the width direction.
The articulated disposable wearing article according to the sixth aspect.

(Effects)
By providing the non-stretchable regions on both sides of the stretchable sheet in this way, it is possible to prevent a situation in which the edge of the finger insertion hole shrinks due to the shrinkage of the stretchable sheet and the appearance deteriorates.

<Eighth aspect>
A liquid-permeable top sheet covering the front side of the absorber,
A liquid-impermeable sheet covering the back side of the absorber and extending to the side of the absorber,
An exterior nonwoven fabric covering the back side of the liquid impermeable sheet,
A root portion fixed to a region including the side flap, a main body portion extending from the root portion, a falling portion in which both ends in the front-rear direction of the main body portion are fixed in a laid state, and a front and rear falling portion of the main body portion A gather sheet having a non-fixed rising portion located between the portions, and a rising gather having a gather elastic member fixed to at least a distal end portion of the rising portion,
The side flap portion is formed by a portion of the gather sheet, the top sheet, the liquid impermeable sheet, and the exterior nonwoven fabric, which is located on a side of the absorbent body,
The region having the divided perforations in the side flap portion has a two-layer structure of the gather sheet and the exterior nonwoven fabric,
The articulated disposable wearing article according to any one of the first to fifth aspects.

(Effects)
In the connection type disposable wearing article, in order to suppress the usage amount of the top sheet and the liquid impermeable sheet, the side sheet does not extend to the side edge of the side flap part, and the side flap part is a gather sheet and a sheet outside the middle in the width direction. It often has a two-layer structure of an exterior nonwoven fabric. Therefore, it is preferable to use such a thin and weak side flap structure and to provide the divided perforations in the two-layer structure portion because the divided perforations are easily torn. In particular, in the structure of the thin and weak side flap part, if the conventional method of dividing the divided perforation from the side edge side and dividing into two upper and lower stages is adopted, the possibility of excessive tearing of the divided perforation increases. Since the disposable wearing article has a finger insertion hole, there is no possibility of excessive tearing.

  FIGS. 1 to 6 show an example of a connection type disposable wearing article, in which X represents the entire width of the diaper excluding the connection tape, and L represents the entire length of the diaper. Indicates a hot melt adhesive as a joining means for joining the constituent members located on the front side and the back side. The hot melt adhesive is formed by a known method such as slot coating, continuous linear or dotted line bead coating, spiral or Z-shaped spray coating, or pattern coating (transfer of hot melt adhesive by letterpress method). Can be applied. Alternatively or together with this, at the fixing portion of the elastic member, a hot melt adhesive can be applied to the outer peripheral surface of the elastic member, and the elastic member can be fixed to the adjacent member. Examples of the hot melt adhesive include EVA-based adhesives, adhesive rubber-based (elastomer-based), olefin-based, and polyester / polyamide-based adhesives, but they can be used without any particular limitation. As a joining means for joining the constituent members, means by material welding such as heat sealing or ultrasonic sealing can be used.

  The connected disposable wearing article includes a crotch portion M including a center in the front-back direction LD, a ventral portion F extending forward from the center in the front-back direction LD, and a back portion B extending rearward from the center in the front-back direction LD. have. Further, the connected disposable wearing article includes an absorbent body 56 incorporated in a range including the crotch portion M, a liquid-permeable top sheet 30 covering the front side of the absorbent body 56, and a liquid impervious material covering the back side of the absorbent body 56. It has a permeable sheet 11 and an exterior nonwoven fabric 12 which covers the back side of the liquid impermeable sheet and constitutes the outer surface of the product.

Hereinafter, the materials and characteristic portions of each part will be described in order.
(Absorber)
The absorber 56 is a portion that absorbs and retains the excreted liquid, and can be formed by an aggregate of fibers. Examples of the fiber aggregate include a filament aggregate obtained by spreading a tow (fiber bundle) of synthetic fibers such as cellulose acetate, as necessary, in addition to fibers obtained by stacking short fibers such as cotton-like pulp and synthetic fibers. Can also be used. The basis weight of fibers, when fiber stacking flocculent pulp or short fibers, for example, be a 100 to 300 g / m ² approximately, in the case of a filament aggregate, for example, be 30 to 120 g / m ² approximately Can be. The fineness of the synthetic fiber is, for example, 1 to 16 dtex, preferably 1 to 10 dtex, and more preferably 1 to 5 dtex. In the case of a filament aggregate, the filament may be a non-crimped fiber, but is preferably a crimped fiber. The degree of crimp of the crimped fiber can be, for example, about 5 to 75 pieces, preferably about 10 to 50 pieces, more preferably about 15 to 50 pieces per 2.54 cm. Further, crimped fibers uniformly crimped can be used.

(Superabsorbent polymer particles)
The absorber 56 can contain superabsorbent polymer particles in a part or the whole thereof. The superabsorbent polymer particles include “powder” in addition to “particles”. As the superabsorbent polymer particles, those used for this type of absorbent article can be used as they are. Although the particle size of the superabsorbent polymer particles is not particularly limited, for example, sieving using a standard sieve of 500 μm (JIS Z8801-1: 2006) (shaking for 5 minutes), and particles falling under the sieving by this sieving When sieving using a 180-μm standard sieve (JIS Z8801-1: 2006) (shaking for 5 minutes), the percentage of particles remaining on the 500-μm standard sieve is 30% by weight or less, and the 180-μm standard sieve is used. It is desirable that the ratio of the particles remaining on the top is 60% by weight or more.

  The material of the superabsorbent polymer particles can be used without any particular limitation, but those having a water absorption of 40 g / g or more are preferred. Examples of the superabsorbent polymer particles include starch-based, cellulose-based and synthetic polymer-based particles, such as starch-acrylic acid (salt) graft copolymer, starch-acrylonitrile copolymer saponified product, and sodium carboxymethylcellulose crosslinking. Or an acrylic acid (salt) polymer can be used. The shape of the superabsorbent polymer particles is preferably in the form of a commonly used powder, but other shapes can also be used.

  As the superabsorbent polymer particles, those having a water absorption rate of 70 seconds or less, particularly 40 seconds or less are suitably used. If the water absorption speed is too slow, the so-called reversion in which the liquid supplied into the absorber 56 returns to the outside of the absorber 56 easily occurs.

  As the superabsorbent polymer particles, those having a gel strength of 1000 Pa or more are preferably used. Thereby, even when the bulky absorber 56 is used, the sticky feeling after absorbing the liquid can be effectively suppressed.

The basis weight of the superabsorbent polymer particles can be appropriately determined according to the absorption required for the use of the absorber 56. Therefore, although it cannot be said unconditionally, it can be usually 50 to 350 g / m ² .

(Packaging sheet)
In order to prevent the superabsorbent polymer particles from coming off or to enhance the shape retention of the absorber 56, the absorber 56 can be incorporated as an absorbing element 50 wrapped in a wrapping sheet 58. As the packaging sheet 58, tissue paper, particularly crepe paper, nonwoven fabric, polylaminated nonwoven fabric, a sheet with small holes, or the like can be used. However, a sheet from which the superabsorbent polymer particles do not escape is desirable. When a nonwoven fabric is used instead of crepe paper, hydrophilic SMMS (spunbond / meltblown / meltblown / spunbond) nonwoven fabric is particularly suitable, and polypropylene, polyethylene / polypropylene or the like can be used as the material. The fiber basis weight is preferably 5 to 40 g / m ² , particularly preferably 10 to 30 g / m ² .

  As shown in FIG. 3, the packaging sheet 58 has a structure in which the entirety of the absorber 56 is wrapped by a single sheet, or a plurality of upper and lower sheets may be used to wrap the entirety of the absorber 56. 58 can also be omitted.

(Top sheet)
The top sheet 30 has liquid permeability, and for example, a perforated or non-porous nonwoven fabric, a porous plastic sheet, or the like can be used.

  The top sheet 30 extends from the front end to the rear end of the product in the front-rear direction, and extends laterally beyond the absorber 56 in the width direction WD. For example, the starting point of the rising gathers 60 described later is closer than the side edge of the absorber 56. If necessary, for example, if the top sheet 30 is located at the center in the width direction, the top sheet 30 can be appropriately deformed, for example, the width of the top sheet 30 is made shorter than the entire width of the absorber 56.

(Intermediate sheet)
An intermediate sheet (also called “second sheet”) 40 can be provided on the back side of the top sheet 30 to prevent the liquid that has passed through the top sheet 30 from returning. The intermediate sheet 40 can be omitted.

As the intermediate sheet 40, various nonwoven fabrics can be suitably used, and particularly a bulky air-through nonwoven fabric can be suitably used. It is preferable to use a conjugate fiber having a core-sheath structure for the air-through nonwoven fabric. In this case, the resin used for the core may be polypropylene (PP), but polyester (PET) having high rigidity is preferable. Basis weight is preferably ^{17~80g / m 2, 25~60g / m} 2 is more preferable. The thickness of the raw material fibers of the nonwoven fabric is preferably 2.0 to 10 dtex. In order to make the nonwoven fabric bulky, it is also preferable to use eccentric fibers or hollow fibers having no core at the center, or eccentric and hollow fibers, as the mixed fibers of all or some of the raw fibers.

  In the illustrated example, the intermediate sheet 40 is disposed at the center shorter than the width of the absorber 56, but may be provided over the entire width. The intermediate sheet 40 may be provided over the entire length of the diaper, or may be provided only in the intermediate portion including the excretion position as shown in the figure.

(Liquid impermeable sheet)
The liquid impermeable sheet 11 is not particularly limited, but preferably has moisture permeability. As the liquid-impermeable sheet 11, for example, a microporous material obtained by kneading an inorganic filler in an olefin-based resin such as polyethylene or polypropylene, forming a sheet, and then stretching the sheet in a uniaxial or biaxial direction. A sheet can be suitably used. Further, as the liquid impermeable sheet 11, a sheet having a non-woven fabric as a base material and having improved waterproofness can be used.

  The liquid impermeable sheet 11 preferably extends over the same or a wider range as the absorber 56 in the front-rear direction LD and the width direction WD, but if necessary, such as when other water shielding means is present, The structure which does not cover the end part of the absorber 56 in the front-back direction LD and the width direction WD can also be used.

(Exterior non-woven fabric)
The exterior nonwoven fabric 12 covers the entire back side of the liquid-impermeable sheet 11 so that the outer surface of the product has a cloth-like appearance. The nonwoven fabric may be used alone or in a plural number. In the latter case, it is preferable to bond the nonwoven fabrics together with a hot melt adhesive or the like. When a nonwoven fabric is used, it is preferable that the constituent fibers have a fineness of 1.0 to 3.5 dtex, a basis weight of 10 to 50 g / m ² , and a thickness of 1 mm or less.

(Get up gather)
In order to prevent the excrement traveling on the top sheet 30 and moving in the lateral direction, and to prevent so-called lateral leakage, rising gathers 60 that stand on the skin side of the wearer are provided on both sides in the width direction WD of the surface. Is preferable. Of course, the rising gathers 60 can be omitted.

  When adopting the rising gathers 60, the structure is not particularly limited, and any known structure can be adopted. The rising gather 60 in the illustrated example includes a root portion 65 fixed to a region including the side flap, a main body portion 66 extending from the root portion, and a both-ends of the main body portion 66 in the front-rear direction fixed to a down state. A gather sheet 62 having a non-fixed rising portion 68 located between the front and rear falling portions 67 of the main body portion 66 and a gather elastic member 63 fixed to at least the distal end of the rising portion 68 It has become. As the gather sheet 62, a water-repellent nonwoven fabric can be used, and as the gather elastic member 63, thread rubber or the like can be used. As shown in FIGS. 1 and 3, a plurality of gather elastic members 63 may be provided, or one gather elastic member 63 may be provided.

  The inner surface of the gather sheet 62 has a joining start end in the width direction WD on the side portion of the top sheet 30, and a portion outside in the width direction from the joining start end is an inner surface of each side flap portion SF, that is, in the illustrated example, liquid impermeable. The side surface of the non-woven sheet 11 and the side portion of the exterior nonwoven fabric 12 located on the outer side in the width direction are joined by a hot melt adhesive or the like.

  Around the legs, the inner side in the width direction from the joining start end of the rising gathers 60 is fixed on the top sheet 30 at both ends in the front-rear direction of the product, but the portion between them is a non-fixed free portion. The elastic member 63 rises due to the contracting force and comes into close contact with the body surface.

(End flap, side flap)
The connection type disposable wearing article of the illustrated example has a pair of end flap portions EF that do not have the absorber 56 and extend to the front side and the rear side of the absorber 56, respectively, and are lateral to both side edges of the absorber 56. And a pair of side flap portions SF that do not have the absorber 56 respectively. The side flap portion SF may be made of a material (exterior nonwoven fabric 12 or the like) continuous from the portion having the absorber 56 as shown in the illustrated example, or may be formed by attaching another material.

(Plane gather)
On each side flap portion SF, a side elastic member 64 made of an elongated elastic member such as thread rubber is fixed in a state of being extended along the front-back direction LD. Are configured as planar gathers. The leg-surrounding elastic member 64 is provided between the gather sheet 62 and the liquid-impermeable sheet 11 on the outer side in the width direction near the joining start end of the joining portion of the gather sheet 62 as shown in the illustrated example. It can also be provided between the liquid impermeable sheet 11 and the exterior nonwoven fabric 12 in SF. As shown in the illustrated example, a plurality of leg surrounding elastic members 64 may be provided on each side, or only one leg surrounding elastic member 64 may be provided on each side.

  The plane gather is a portion where the contraction force of the side elastic member 64 acts (a portion where the side elastic member 64 is shown in the drawing). Therefore, in addition to the form in which the side elastic member 64 exists only in the portion of the flat gather, the side elastic member 64 exists on the front side, the rear side, or both sides of the flat gather, but the side elastic member 64 exists in other than the portion of the flat gather. When the member is finely cut at one or many places, or is not fixed to the sheet sandwiching the side elastic member 64, or both, a contraction force acts on a portion other than the flat gather. However, there is also included a structure in which the contraction force of the side elastic member 64 acts only on the portion of the flat gathers (substantially equivalent to not providing the elastic member).

(Wing part)
In the present connection type disposable wearing article, the back side portion B has a wing portion WP extending outward in the width direction WD from the crotch portion M. Similarly, the abdominal portion F also has a wing portion WP extending outward in the width direction WD from the crotch portion M. These wing portions WP can be formed by other members than the other portions. However, in the structure having the side flap portion SF as shown in the figure, by cutting the middle in the front-rear direction LD at the side portion of the side flap portion SF, the concave shape from the side edge of the crotch portion M to the lower edge 71 of the wing portion is formed. It is preferable that the edge 70 is formed, and as a result, the wing portion WP is formed because manufacturing is easy.

(Connecting tape)
As shown in FIGS. 1, 2, and 6, connecting tapes 80 </ b> A and 80 </ b> B that are detachably connected to the outer surface of the abdominal part F are provided on the wing part WP of the back part B. . When the diaper 10 is mounted, the connecting tapes 80A and 80B are turned from both sides of the waist to the outer surface of the abdominal portion F, and the connecting portions 83 of the connecting tapes 80A and 80B are connected to appropriate positions on the outer surface of the abdominal portion F.

  As shown in FIGS. 6 and 9, the connection tapes 80 </ b> A and 80 </ b> B include a base end portion 81 fixed to the wing portion WP, and a sheet base material 80 </ b> S forming a main body portion 82 extending from the base end portion 81. The sheet base 80 </ b> S has a connection part 83 to the abdominal part F provided at an intermediate part of the main body part 82 in the width direction WD. In the main body 82, the base end 81 side of the connection part 83 is a non-connection part 84 not connected to the abdominal part F, and the opposite side is a knob part 85. The non-connection portion 84 and the knob portion 85 are formed only of the sheet base material 80S that forms the main body portion 82. The side edge of the base end portion 81 may coincide with the side edge of the wing portion WP, or, as shown in FIG. 6, is slightly separated inward in the width direction WD from the side edge of the wing portion WP. Is also good. This separation distance can be about 10 to 50 mm. The inner edge in the width direction of the connecting portion 83 may coincide with the side edge of the wing portion WP, but as shown in FIG. 6, the outer edge in the width direction WD is sufficiently extended from the side edge of the wing portion WP. It is preferred that they are separated. This separation distance can be about 1 to 100 mm.

  As the connecting portion 83, a hook material (male material) of a mechanical fastener (surface fastener) may be provided, or an adhesive layer may be provided. The hook member has a large number of engaging projections on its connection surface. The shape of the engaging projection is (A) L-shaped, (B) J-shaped, (C) mushroom-shaped, (D) There are a T-shape, (E) a double J-shape (a shape in which J-shapes are joined back to back) and the like, but any shape may be used.

In addition, as the sheet base material 80S that forms the base end portion 81 to the main body portion 82, a nonwoven fabric, a plastic film, a polylaminated nonwoven fabric, paper, or a composite material thereof can be used, but the fineness is 1.0 to 3.5 dtex. Spunbond nonwoven fabric, air-through nonwoven fabric, or spunlace nonwoven fabric having a basis weight of 60 to 100 g / m ² and a thickness of 1 mm or less is preferable.

  The connecting tapes 80A and 80B may be such that at least a part of the non-connecting portion 84 expands and contracts in the width direction WD, or may not entirely expand and contract.

(Target part)
A target portion 20 is provided at a connection point of the connection tapes 80A and 80B in the abdominal portion F. The target portion 20 can be provided by attaching a sheet material for facilitating connection to the outer surface of the abdominal portion F as in the illustrated example.

  The sheet material for forming the target portion 20 is not particularly limited, but when the connecting portion 83 is a hook material, for example, long fibers in which fibers are partially welded to each other by ultrasonic welding in an intermittent pattern. Non-woven fabric can be used.

  In the case where the connecting portion 83 is a hook material, a large number of loop threads on which the engaging projections of the hook material are entangled are sewn on the surface of the base material made of a plastic film or a nonwoven fabric as a sheet material for forming the target portion 20. A composite sheet material obtained can be used.

  Further, when the connecting portion 83 is a hook material and the connecting portion of the connecting tapes 80A and 80B in the abdominal portion F is made of a nonwoven fabric (for example, when the exterior nonwoven fabric 12 is provided as in the illustrated example), the target portion 20 is not used. Instead of adding a sheet material, a suitable portion of the exterior nonwoven fabric 12 may be used as the target portion 20 and a hook material may be entangled with fibers of the exterior nonwoven fabric 12 and connected.

  On the other hand, in the case where the connecting portion 83 is an adhesive material layer, the surface of a sheet material made of a plastic film having a smooth adhesive surface was subjected to a release treatment as a sheet material for forming the target portion 20. Can be used.

(Elastic sheet)
An elastic sheet 17 that elastically expands and contracts in the width direction WD is attached between the left and right connecting tapes 80A and 80B in the back part B, and a region having the elastic sheet 17 elastically expands and contracts in the width direction WD. Is preferred. The elastic sheet 17 may be located only at the end flap portion EF, but if it is arranged to extend from the end flap portion EF to the rear end portion of the absorber 56 as shown in the illustrated example, This is preferable because the rear end is firmly pressed against the body.

  The elastic sheet 17 may use a sheet-like elastic member such as a rubber sheet, but preferably has air permeability. In this case, an air-permeable sheet-like elastic member such as a stretchable nonwoven fabric can be used. However, as shown in FIGS. 5 and 7, the support layer 18 such as two nonwoven fabrics is bonded with a hot melt adhesive or the like. It is preferable that an elastic member 19 such as a perforated sheet-like, net-like, or elongated (filament-like or string-like) is fixed between the two support layers 18 in a state of extending along the width direction WD. Used for In this case, as the material of the support layer 18, the same material as the exterior nonwoven fabric 12 can be used. It is preferable that the elongation rate of the elastic member 19 is about 150 to 250%. In the case of using an elongated member (such as a string or a string) as the elastic member 19, it is preferable to provide approximately 5 to 15 rods having a thickness of 420 to 1120 dtex at an interval 19d of 3 to 10 mm.

  The width of the elastic sheet 17 can be appropriately determined, but is preferably a width extending between the left and right side flap portions SF as in the illustrated example. As a specific dimension, the width of the elastic sheet 17 is preferably about 80 to 95% of the total width X of the main body portion excluding the connecting tapes 80A and 80B.

  Both ends of the stretchable sheet 17 in the width direction WD may be non-stretchable regions 17n for holding and attaching by suction during manufacturing. The dimension of the non-stretchable area 17n and the dimension of the intermediate stretchable area 17e located between them and expanding and contracting in the width direction WD can be determined as appropriate, but the width of the intermediate stretchable area 17e is determined by the left and right connecting tapes 80A, It is preferable that the width between the connecting portions 83 of 80B is 45 to 90%, and the width of the non-stretchable area 17n is about 5 to 50 mm in order to prevent shrinkage and curling during manufacturing. The non-stretchable region 17n may be a region without the elastic member 19, but the elastic member 19 is attached over the intermediate stretchable region 17e and the non-stretchable region 17n, and the elastic member 19 is cut in the non-stretchable region 17n. A structure in which the elastic member 19 remains in the region 17n but hardly or never expands or contracts may be employed.

  In addition, the elastic member 19 can be arranged so that a part thereof crosses the absorber 56. However, as shown in FIG. 7, the elastic member 19 cuts a part or all of a portion overlapping the absorber 56. Accordingly, if the elastic member 19 remains but hardly or not at all expands and contracts, the rear end portion of the absorber 56 does not shrink in the width direction, so that the fitting property is further improved.

  The elastic sheet 17 is disposed between the liquid impermeable sheet 11 and the absorbing element 50 in the illustrated example, but is not particularly limited to this arrangement. For example, the stretch sheet 17 may be disposed between the liquid impermeable sheet 11 and the exterior nonwoven fabric 12 or may be provided outside the exterior nonwoven fabric 12.

(Divided perforation)
Characteristically, as shown in an enlarged manner in FIG. 9, the first connecting tape 80A provided on the waist side (rear side) of the wing portion WP and the leg surrounding side (front side) of the wing portion WP. A second connecting tape 80B provided on the side. The side flap portion SF includes a divided perforation 90 extending inward in the width direction WD from a portion between the first connecting tape 80A and the second connecting tape 80B at a side edge of the wing portion WP, and a divided perforation 90. And a finger insertion hole 98 adjacent to the inner end in the width direction WD.

  In use, the present articulated disposable wearing article inserts a finger into the finger insertion hole 98 and moves the finger to the side of the divided perforation 90, or pinches the side of the divided perforation 90 with the finger, and Are sequentially cut from the inner side to the outer side in the width direction WD, at least a part of the wing portion WP can be divided into upper and lower stages UP and LP as shown in FIG. Then, the upper part UP having the waist-side first connecting tape 80A is connected while being pulled obliquely downward, so that the waist is firmly tightened, and the lower part LP having the second waist-side second connecting tape 80B is inclined obliquely upward. By pulling and connecting, the circumference of the leg can be securely tightened. In particular, since the wing portion WP which is not conventionally divided is divided into two stages and can be independently fitted to the circumference of the waist and the periphery of the leg, respectively, a more securely fitted state than the conventional one can be obtained. Things. The connection position of the first connection tape 80A and the second connection tape 80B can be appropriately determined by the user, and as shown in FIG. 8 (b), the positional relationship of the connecting portions 83 may be reversed, and the connecting portions 83 may not overlap, as shown in FIG. 8 (b). The connecting portions 83 may partially overlap each other. Further, if necessary, the divided perforations 90 can be used without being separated.

  In addition, since the present connection-type disposable wearing article is provided with a division perforation 90 in the side flap portion SF and divided into two upper and lower stages, the first connection tape 80A on the waist side is directed obliquely downward and around the leg circumference. Even if the second connecting tapes 80B are connected diagonally upward, large wrinkles are unlikely to come close to the wing portions WP, and the appearance is hardly deteriorated.

  Further, when a divided perforation 90 is provided on the side flap portion SF and the divided perforation 90 is separated from the side edge side and divided into upper and lower two stages, when the divided perforation 90 is torn to the inner end, the divided perforation 90 is divided. There is a possibility that the side flap portion SF may be torn to a portion further inside than the inner end of the side flap (hereinafter, also referred to as excessive tearing). On the other hand, when a finger is inserted into the finger insertion hole 98 as described above and the divided perforations 90 are cut outward from the inside in the width direction WD, excessive tearing does not occur. Further, since the finger insertion hole 98 is a conspicuous portion, there is also an advantage that there is little risk that the finger insertion hole is lost as in a slit or that it becomes difficult to insert the finger.

  In the present connection type disposable wearing article, since the perforations 90 are formed in the side flap portions SF, the dimension 80w of the connection tapes 80A and 80B in the width direction WD can be reduced. For example, the dimension 80w of the connecting tapes 80A and 80B in the width direction WD can be set to be 1/7 to 1/2 times the dimension X of the portion of the back part B except the connecting tapes 80A and 80B in the width direction WD. . As a result, in the present concatenated disposable wearing article, the effect of the hardness of the connecting tapes 80A, 80B on the feeling of wearing is reduced while a tightly fitted mounting state is obtained by the upper and lower connecting tapes 80A, 80B. can do. The dimension of the connecting tape 80A, 80B in the front-back direction LD can be determined as appropriate, but can be, for example, less than half the size of the side edge of the wing portion WP in the front-back direction LD.

  The first connecting tape 80A and the second connecting tape 80B may have the same size and shape as in the illustrated example, or may differ in at least one of the size and shape. The first connecting tape 80A and the second connecting tape 80B may be attached to the waist side or the leg circumference side in the wing portion WP, but in a normal case, the waist side from the center in the longitudinal direction LD of the wing portion WP. Preferably, the first connecting tape 80A is attached to the wing portion WP, and the second connecting tape 80B is attached to the leg circumference side from the center of the wing portion WP in the front-rear direction LD. In order to form the divided perforations 90 between the first connecting tape 80A and the second connecting tape 80B, the first connecting tape 80A and the second connecting tape 80B have a sufficient interval in the front-rear direction LD, for example, an interval of 15 mm or more. It is preferable that they are adjacent to each other as long as the divided perforations 90 can be formed.

  The vertical position of the divided perforation 90 is located at the center in the front-rear direction LD between the first connecting tape 80A and the second connecting tape 80B. It may be biased toward the two connecting tapes 80B. In the normal case, the divided perforations 90 are preferably located within a range of ± 5 mm in the front-rear direction LD with respect to the center of the wing portion WP in the front-rear direction LD.

  The size of the divided perforations 90 in the width direction WD can be appropriately determined, but is preferably 15 mm or more, and particularly preferably 40 mm or more. Also, as shown in FIGS. 6 and 9, it is preferable that the inner end of the divided perforation 90 is located laterally to the side edge of the top sheet 30 and the side edge of the liquid impermeable sheet 11.

  The number of divided perforations 90 may be one as shown in the illustrated example, or may be plural. In this case, although not shown, a finger insertion hole 98 can be provided corresponding to each divided perforation 90.

  As shown in FIG. 10, the width of the tie portion 91 t of the first portion 91 located laterally with respect to the middle in the width direction WD in the divided perforations 90 is located inward of the first portion 91 in the width direction WD. One preferable example is to make the tie portion 92t of the second portion 92 wider than the width of the tie portion 92t. The tie portion is the width of the non-cut portion between the adjacent cut portions 91c and 92c, and is equal to the interval between the adjacent cut portions 91c and 92c. As described above, if the divided portion 90 is easily torn in the second portion 92 to a certain extent from the beginning of the tearing of the divided perforation 90, and if the divided portion 90 is difficult to be torn in the subsequent first portion 91, the separation of the divided perforation 90 can be easily started. , The wing portion WP can be easily divided into upper and lower tiers. In addition, when the divided perforations 90 are used without being separated, the situation in which the divided perforations 90 are unintentionally separated is less likely to occur.

(Finger insertion hole)
The finger insertion hole 98 only needs to extend from a position adjacent to the inner end of the divided perforation 90 in the width direction WD. The position adjacent to the inner end of the divided perforation 90 in the width direction WD means a position that is close enough to start separating the divided perforation 90 from the finger insertion hole 98. In a normal case, if the interval 98t between the finger insertion hole 98 and the cut portion of the divided perforation 90 adjacent to the finger insertion hole 98 is equal to or less than the length of the tie portion 90t of the divided perforation 90, like the divided perforation 90, The separation of the divided perforations 90 from the finger insertion holes 98 can be started.

  The finger insertion hole 98 is formed by punching out a target portion, and has both a dimension 98y in the front-back direction LD and a dimension 98x in the width direction WD in the unfolded state and has a shape as long as it has an area. There is no particular limitation. The finger insertion hole 98 is, for example, circular as shown in FIGS. 1, 2, 9, and 10, an ellipse, a polygon such as a triangle as shown in FIG. 12, a cloud, or a star. And so on.

  In particular, as in the example shown in FIG. 11 and the example shown in FIG. 12, at least the upper edge e <b> 1 and the lower edge e <b> 2 of the finger insertion hole 98 located on the outer side in the width direction WD correspond to the divided perforations 90. It is preferable that the finger extends toward the inner end in the width direction WD because the moving direction of the finger toward the divided perforation 90 can be easily understood. Further, with the movement of the finger toward the divided perforations 90, the upper edge e1 and the lower edge e2 are gradually pushed apart and spread, and a force for tearing the divided perforations 90 is applied, so that the tearing of the divided perforations 90 also starts smoothly. . Note that the finger insertion hole 98 in the example shown in FIG. 11 has a circular portion into which a finger is inserted first, and a laterally triangular portion indicating a tearing direction (having vertices outward in the width direction and inward in the width direction). Has a bottom side). On the other hand, the finger insertion hole 98 in the example shown in FIG. 12 has a generally horizontal triangular shape (having a vertex outward in the width direction and having a base inward in the width direction).

  The dimension of the finger insertion hole 98 can be appropriately determined as long as the tip of the finger can be inserted. In a normal case, the dimension 98y of the front-back direction LD is 8 to 18 mm and the dimension 98x of the width direction WD is 8 to 18 mm. It is preferable that the distance is 18 mm because the index finger can be easily inserted and the trace of the finger insertion hole 98 does not become large after the split perforation 90 is torn.

(Extension of stretch sheet)
With the finger insertion hole 98, when the divided perforation 90 is separated and used, the corner formed from the edge of the finger insertion hole 98 to the divided perforation 90 flutters, and the appearance and the wearing feeling are improved. May worsen. Therefore, as shown in FIG. 9 and the like, it is proposed to extend the above-described elastic sheet 17 provided on the back part B to the side of the finger insertion hole 98. As described above, when the elastic sheet 17 is extended to the side of the finger insertion hole 98 to increase the rigidity of the region including the finger insertion hole 98, after the separation of the divided perforation, the edge of the finger insertion hole 98 moves to the divided perforation 90. This is preferable because the corners formed at the leading portions are less likely to flutter. This structure is also preferable in terms of effective use of the elastic sheet 17 for improving the fit around the waist.

  The portion overlapping the elastic sheet 17 is contracted together with the elastic sheet 17 in a natural length state. For this reason, if the intermediate elastic region 17 e of the elastic sheet 17 is present up to the portion overlapping the finger insertion hole 98, the edge of the finger insertion hole 98 may be shrunk by the contraction of the elastic sheet 17 and turned up. Therefore, as shown in FIG. 9 and the like, it is preferable that the non-stretchable region 17n of the stretchable sheet 17 extends to the side from the inner end of the finger insertion hole 98 in the width direction WD. Accordingly, it is possible to prevent a situation in which the edge of the finger insertion hole 98 is contracted due to the contraction of the elastic sheet 17 and the appearance is deteriorated.

(Non-woven fabric)
As the nonwoven fabric in the above description, a known nonwoven fabric can be appropriately used depending on the site and purpose. Examples of the constituent fibers of the nonwoven fabric include olefin-based synthetic fibers such as polyethylene and polypropylene, polyester-based and polyamide-based synthetic fibers (including composite fibers such as core-sheaths as well as monocomponent fibers), as well as regeneration of rayon and cupra. Fibers, natural fibers such as cotton, and the like can be selected without particular limitation, and these can be used in combination. In order to increase the flexibility of the nonwoven fabric, it is preferable that the constituent fibers are crimped fibers. In addition, even if the constituent fibers of the nonwoven fabric are hydrophilic fibers (including hydrophobic fibers made hydrophilic by a hydrophilizing agent), hydrophobic fibers or water-repellent fibers (water-repellent water repellent by a water repellent) are used. (Including aqueous fibers). In addition, non-woven fabrics generally have short fiber non-woven fabrics, long fiber non-woven fabrics, spun bond non-woven fabrics, melt blown non-woven fabrics, spun lace non-woven fabrics, thermal bond (air through) non-woven fabrics, and needle punches depending on the fiber length, sheet forming method, fiber bonding method, and laminated structure. Nonwoven fabrics, point-bonded nonwoven fabrics, laminated nonwoven fabrics (SMS nonwoven fabrics having a melt blown layer between spunbond layers, SMMS nonwoven fabrics, and the like) and the like can be used, and any of these nonwoven fabrics can be used.
