Description

  The present invention relates to a disposable diaper for pets.

  Recently, disposable diapers for pets that have been used on dogs and cats have been proposed. For example, the device described in Patent Document 1 includes a back side portion for covering the back and a main body portion for covering from the abdomen through the crotch to the vicinity of the root of the tail, and protrudes from both sides of the main body portion. The fastening tape is a fixed type that is mounted by detachably locking the fastening tape to a target tape provided on the outer surface of the back portion. The body part is functionally divided into an anus below the base of the tail and a buttock covering part for covering the lower part of the anus and a ventral part for covering the abdomen in front of the buttock covering part. be able to.

  One of the characteristic parts in the disposable diaper for pets is a tail through portion that penetrates the front and back formed at the tail root opposing portion. At the time of mounting, the tail is passed through the tail through part as necessary. Conventionally, as the tail-through portion, the position and size can be changed by separating the perforation in addition to the opening type (see Patent Documents 1 and 2) in which a tail-through hole of a predetermined size is previously opened at a predetermined position. A perforation type (see Patent Document 3) and a slit extending from the tail root facing part to the front end of the dorsal part are formed in advance. A slit type (see Patent Documents 4 and 5) in which the fastening tape is fixed by crossing at the front side (cross-stopping) has been proposed.

JP 2004-159591 A Japanese Patent No. 3773622 Japanese Patent Laid-Open No. 10-75679 JP 2009-273407 A Japanese Patent No. 4201798

  However, even though the conventional tail-through part can be dimensionally changed like the perforated type, it does not completely fit the tail thickness of individual pets, and the dog has a tail that is narrower than the design. In this case, there is a possibility that a gap is formed between the tail passage part and the anal side edge at the base of the tail, and excrement may leak from this gap.

  In order to solve this problem, Patent Document 1 discloses a technique in which a winding member separate from the diaper is wound around the peripheral edge of the tail through hole, and the peripheral edge of the tail through hole is squeezed to adhere to the outer periphery of the tail. Although it has been proposed, not only a separate winding member is required, but also the winding member is separate, so that the winding work is difficult, for example, the position is easily shifted.

  Therefore, the main problem of the present invention is that a separate member is not required, and it is difficult to form a gap between the tail passage part and the anal side edge at the base of the tail, so that excrement from the tail passage part can be prevented. It is to prevent leakage.

This disposable diaper for pets has a main body portion 10 extending in one longitudinal direction so as to cover the crotch through the crotch from the anal side edge at the base of the tail, and the back side from the anal side edge at the base of the tail. A back side portion B extending to the other side in the longitudinal direction so as to cover, and a fastening tape 13 provided as a locking portion for the back side portion B provided on both side portions of the main body portion 10 are provided. The main body 10 can be divided into an anus below the base of the tail and a buttock covering portion M for covering the vicinity of the lower side, and an abdominal portion F for covering the abdomen in front of the buttock covering portion M. it can.

  The disposable diaper includes an absorbent holding portion in which an absorbent element 50 is interposed between the liquid-permeable surface sheet 30 that forms the body-side surface and the liquid-impermeable sheet 11 that is positioned on the outer surface side, and both front and rear sides thereof. And an end flap portion EF and a side flap portion SF that are portions that extend to the left and right sides, respectively, and that do not have the absorbent element 50, and in this example, are absorbed and held in the main body portion 10. A portion is provided, and the back side portion B is not provided.

  As the laminated structure, the entire outer surface of the disposable diaper is formed by the exterior sheet 12, and in the absorption holding portion having the absorbent element 50, the liquid-impermeable sheet 11 is formed on the inner surface side of the exterior sheet 12 with a hot melt adhesive or the like. The absorbent element 50, the intermediate sheet 40, and the top sheet 30 are laminated in this order on the inner surface side of the liquid-impermeable sheet 11. The top sheet 30 and the liquid-impermeable sheet 11 are rectangular in the illustrated example, have slightly larger dimensions in the longitudinal direction and the width direction than the absorbent element 50, and are eaten from the side edges of the absorbent element 50 in the top sheet 30. The peripheral edge that protrudes and the peripheral edge that protrudes from the side edge of the absorbent element 50 in the liquid-impermeable sheet 11 are fixed by a hot melt adhesive or the like. The liquid-impermeable sheet 11 is made of a moisture-permeable polyethylene film or the like, and is formed to be slightly wider than the top sheet 30.

  Further, on both sides of the absorbent main body 10, side solid gathers 60, 60 that protrude (stand up) toward the pet's skin are provided, and a gather sheet 62 that forms the side solid gathers 60, 60. , 62 extend over the entire inner surface of the side flap portion SF from both side portions of the topsheet 30.

Hereinafter, the material and the characteristic part of each part are demonstrated in order.
(Exterior sheet)
The exterior sheet 12 is a part that supports the absorbent element 50 and is attached to a pet. The exterior sheet 12 has an hourglass shape in which the middle portions in the vertical direction on both sides are confined, and this is a portion along the circumference of the pet's leg.
The exterior sheet 12 is preferably a non-woven fabric, but is not limited thereto. The type of the nonwoven fabric is not particularly limited, and as the material fiber, for example, synthetic fibers such as polyethylene or polypropylene, synthetic fibers such as polyester or polyamide, recycled fibers such as rayon or cupra, and natural fibers such as cotton are used. As a processing method, a spunlace method, a spunbond method, a thermal bond method, an air-through method, a needle punch method, or the like can be used. However, a long-fiber nonwoven fabric such as a spunbond nonwoven fabric, an SMS nonwoven fabric, or an SMMS nonwoven fabric is preferable in that both the touch and strength can be achieved. In addition to using a single nonwoven fabric, a plurality of nonwoven fabrics can be used. In the latter case, the nonwoven fabrics 12 are preferably bonded to each other with a hot melt adhesive or the like. When using a nonwoven fabric, the fabric weight is preferably 10 to 50 g / m ² , particularly 15 to 30 g / m ² .

(Liquid impervious sheet)
The material of the liquid-impermeable sheet 11 is not particularly limited. For example, the liquid-impermeable sheet 11 is substantially made of an olefin resin such as polyethylene or polypropylene, a laminated nonwoven fabric obtained by laminating a nonwoven fabric on a polyethylene sheet, or a waterproof film. Non-woven fabrics that ensure liquid impermeability (in this case, liquid impervious sheets are composed of waterproof films and non-woven fabrics). Of course, in addition to this, a liquid-impermeable and moisture-permeable material that has been used and used in recent years from the viewpoint of preventing stuffiness can also be exemplified. As the sheet of the material having liquid impermeability and moisture permeability, for example, an inorganic filler is kneaded in an olefin resin such as polyethylene or polypropylene, and the sheet is formed, and then stretched in a uniaxial or biaxial direction. Examples of the microporous sheet obtained in this way can be given. In addition, non-woven fabric using micro-denier fiber, strengthening leak-proofing by reducing the voids of the fiber by applying heat or pressure, and applying water-absorbing resin or hydrophobic resin or water repellent. A sheet that is liquid-impermeable without using a film can also be used as the liquid-impermeable sheet 11.

(Surface sheet)
The top sheet 30 is sufficient if it has liquid permeability, and for example, a porous or non-porous nonwoven fabric or a porous plastic sheet can be used. Of these, the nonwoven fabric is not particularly limited as to what the raw fiber is. For example, synthetic fibers such as olefins such as polyethylene and polypropylene, polyesters and polyamides, recycled fibers such as rayon and cupra, natural fibers such as cotton, and mixed fibers and composite fibers using two or more of them. Etc. can be illustrated. Furthermore, the nonwoven fabric may be manufactured by any processing. Examples of the processing method include known methods such as a spunlace method, a spunbond method, a thermal bond method, a melt blown method, a needle punch method, an air through method, and a point bond method. For example, the spun lace method is a preferable processing method for obtaining flexibility and drapeability, and the thermal bond method is for obtaining bulkiness and softness.
Further, the top sheet 30 may be composed of one sheet or may be composed of a laminated sheet obtained by bonding two or more sheets. Similarly, the top sheet 30 may be composed of one sheet or two or more sheets in the planar direction.

(Intermediate sheet)
An intermediate sheet (also referred to as a second sheet) 40 can be provided between the surface sheet 30 and the absorbent element 50 in order to move excrement that has passed through the surface sheet 30 to the absorber and prevent reversal. This intermediate sheet 40 not only improves the absorption performance of the absorbent by quickly transferring the excrement to the absorber, but also prevents the excretion of the absorbed excrement from reversing from the absorber, and the surface of the top sheet 30 has a good touch. To do. The intermediate sheet 40 can be omitted.
As the intermediate sheet 40, the same material as that of the top sheet 30 can be used. The intermediate sheet 40 is preferably bonded to the top sheet 30. When heat embossing or ultrasonic welding is used for the bonding, the material of the intermediate sheet 40 preferably has a melting point similar to that of the top sheet 30. Further, in the case where a perforated sheet is used for the top sheet 30, the fineness of the fiber used for the intermediate sheet 40 is preferably 5.0 to 7.0 dtex in consideration of permeation of solid content in feces. The liquid residue in the surface sheet 30 increases. On the other hand, when the fineness of the fiber used for the intermediate sheet 40 is 1.0 to 2.0 dtex, the liquid residue of the top sheet 30 is hardly generated, but the solid content of the stool is hardly transmitted. Therefore, it is preferable that the fiber of the nonwoven fabric used for the intermediate sheet 40 has a fineness of about 2.0 to 5.0 dtex.
The intermediate sheet 40 in the illustrated form is arranged in the center shorter than the width of the absorbent element 50, but may be provided over the entire width. The length in the longitudinal direction of the intermediate sheet 40 may be the same as the entire length of the diaper, may be the same as the length of the absorbent element 50, or may be within a short length range centered on the region that receives the liquid.

(Side three-dimensional gather)
In order to prevent urine and soft stool that move laterally on the top sheet 30 and prevent side leakage, side solid gathers 60, 60 that protrude (stand up) on the use surface side are provided on both sides of the product. Is preferred.
The side three-dimensional gather 60 includes a gather sheet 62 that is substantially continuous in the width direction, and an elongated elastic elastic member 63 that is fixed to the gather sheet 62 in a stretched state along the longitudinal direction. As the gather sheet 62, a water-repellent nonwoven fabric can be used, and as the elastic elastic member 63, rubber thread or the like can be used. As shown in FIGS. 1 and 2, a plurality of elastic elastic members can be provided in addition to a plurality of elastic expansion members.
The inner surface of the gather sheet 62 has a fixing start end in the width direction on the side portion of the top sheet 30, and a portion on the outer side in the width direction from the fixing start end is on the side portion of the liquid-impermeable sheet 11 and on the outer side in the width direction. It fixes to the side part of the exterior sheet | seat 12 located with the hot-melt-adhesive agent etc.
Around the leg, the width direction inner side from the fixing start end of the side three-dimensional gather 60 is fixed on the top sheet 30 at both ends in the product vertical direction, but the portion between them is an unfixed free part, and this free The portion comes to stand by the contraction force of the rubber thread 63. When the diaper is worn, the diaper is attached to the body in the shape of a boat, and the contraction force of the rubber thread 63 acts. Therefore, the side three-dimensional gather 60 stands up due to the contraction force of the rubber thread 63 and comes into close contact with the legs. . As a result, so-called side leakage from around the legs is prevented.
Unlike the illustrated embodiment, the longitudinal end portions of the gather sheet 62 on the inner side in the width direction are divided into a base end side portion extending from the outer side in the width direction to the inner side in the width direction and a center side in the width direction of the base end side portion. It is also possible to fix in a double-folded state having a distal end side portion that is folded back from the edge toward the body side and extends outward in the width direction, and the portion in between can be an unfixed free portion.

(Side edge elastic elastic member)
A side edge elastic elastic member 64 is fixed to each side flap part SF in a state of being extended along the vertical direction. More specifically, an elongated shape as the side edge elastic elastic member 64 is provided between the sheets of the portion where the gather sheet 62 and the exterior sheet 12 face each other on the outer side in the width direction in the vicinity of the fixing start end of the fixed portion of the gather sheet 62. A plurality of elastic elastic members are clamped along the vertical direction and at intervals in the width direction.

(Absorption element)
The absorption element 50 is a part that absorbs and holds liquid such as urine and loose stool. The absorbent element 50 includes an absorbent body 56 and a packaging sheet 58 that wraps at least the back and side surfaces of the absorbent body 56. The packaging sheet 58 can be omitted. The absorbent element 50 can be adhered to the inner surface of the liquid-impermeable sheet 11 via an adhesive such as a hot melt adhesive on the back surface.

(Absorber)
The absorber 56 can be formed of an aggregate of fibers. As this fiber assembly, a filament assembly obtained by opening, as necessary, synthetic fiber tows (fiber bundles) such as cellulose acetate as well as short fibers such as cotton-like pulp and synthetic fibers Can also be used. The fiber basis weight can be set to, for example, about 100 to 300 g / m ² when cotton-like pulp or short fibers are stacked, and in the case of a filament aggregate, for example, about 30 to 120 g / m ^2. Can do. The fineness in the case of a synthetic fiber is 1-16 dtex, for example, Preferably it is 1-10 dtex, More preferably, it is 1-5 dtex. In the case of a filament aggregate, the filament may be a non-crimped fiber, but is preferably a crimped fiber. The crimped degree of the crimped fiber can be, for example, 5 to 75, preferably 10 to 50, and more preferably about 15 to 50 per inch. Further, a crimped fiber that is uniformly crimped is often used. In addition, the code | symbol 56W and 56L in a figure has each shown the vertical direction length and width | variety of an absorber.

(Superabsorbent polymer particles)
The absorbent body 56 preferably includes superabsorbent polymer particles. In particular, at least in the liquid receiving region, the superabsorbent polymer particles (SAP particles) are dispersed substantially throughout the thickness direction with respect to the aggregate of fibers. Is desirable.
If there is no SAP particle in the upper part, the lower part, and the middle part of the absorber 56, or if there is very little, it cannot be said that the "absorbed throughout the thickness direction". Therefore, “distributed in the entire thickness direction” means “distributed unevenly in the upper part, the lower part, and / or the middle part of the aggregate of fibers in addition to the form“ uniformly ”distributed in the entire thickness direction. However, it is still included in the form of being dispersed in the upper, lower and middle portions. Further, a form in which some SAP particles do not enter the fiber assembly and remain on the surface thereof, and a form in which some SAP particles pass through the fiber assembly and are on the packaging sheet 58 are also excluded. It is not something.
Superabsorbent polymer particles include “powder” in addition to “particles”. As the particle diameter of the superabsorbent polymer particles, those used in this type of absorbent article can be used as they are, and those having a particle size of 1000 μm or less, particularly 150 to 400 μm are desirable. 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 suitable. High-absorbent polymer particles include starch-based, cellulose-based, and synthetic polymer-based starch-acrylic acid (salt) graft copolymers, saponified starch-acrylonitrile copolymers, and sodium carboxymethylcellulose crosslinks. Or an acrylic acid (salt) polymer can be used. As the shape of the superabsorbent polymer particles, a commonly used granular material is suitable, but other shapes can also be used.
As the superabsorbent polymer particles, those having a water absorption rate of 40 seconds or less are preferably used. When the water absorption speed exceeds 40 seconds, so-called reversion in which the liquid supplied into the absorber 56 returns to the outside of the absorber 56 is likely to occur.
The basis weight of the superabsorbent polymer particles can be appropriately determined according to the amount of absorption required for the use of the absorber 56. Therefore, although it cannot be said unconditionally, it can be set to 50 to 350 g / m ² . If the amount of polymer is less than 50 g / m ^2, it is difficult to secure the absorption amount. When it exceeds 350 g / m ² , not only the effect is saturated, but also the sensation of incongruity due to the excess of the superabsorbent polymer particles is given.

(Packaging sheet)
When the packaging sheet 58 is used, as the material, tissue paper, particularly crepe paper, non-woven fabric, polylaminated non-woven fabric, a sheet with small holes, or the like can be used. However, it is desirable that the superabsorbent polymer particles be a sheet that does not escape. When a nonwoven fabric is used instead of the crepe paper, a hydrophilic SMMS (spunbond / meltblown / meltblown / spunbond) nonwoven fabric is particularly suitable, and polypropylene, polyethylene / polypropylene, etc. can be used as the material. The fiber basis weight is preferably 5 to 40 g / m ² , particularly 10 to 30 g / m ² .
As shown in FIG. 3, the packaging sheet 58 may wrap only the back surface and the side surface of the layer in addition to the form for wrapping the entire absorbent body 56. Although not shown, only the upper and side surfaces of the absorbent body 56 are covered with crepe paper or a nonwoven fabric, and the lower surface is covered with a liquid-impermeable sheet such as polyethylene, and the upper surface of the absorbent body 56 is covered with crepe paper or a nonwoven fabric. For example, the lower surface may be covered with a liquid-impermeable sheet such as polyethylene (each of these materials is a component of the packaging sheet). If necessary, the absorbent body 56 may be sandwiched between two upper and lower sheets or disposed only on the lower surface, but this is not desirable because it is difficult to prevent the movement of the superabsorbent polymer particles.

(Fastening tape)
As shown in FIGS. 1 and 2, the fastening tape 13 has a base portion of a sheet base material 13C made of a nonwoven fabric, a plastic film, a polylaminated nonwoven fabric, paper or a composite material thereof attached to the diaper and protrudes from the diaper. A hook material 13 </ b> A of a mechanical fastener is provided as a locking portion for the ventral side at the distal end side portion. The hook material 13A is joined to the sheet base 13C with an adhesive so as not to be peeled off.

  In the normal case, the length of the diaper in the width direction is preferably 10 to 50 mm, particularly preferably 20 to 40 mm, and the longitudinal length is 20 to 100 mm, particularly 40 to 40 mm. 80 mm is preferable. Of the dimensions of the front end portion of the fastening tape 13, the length in the width direction of the diaper is preferably 30 to 80 mm, particularly preferably 40 to 60 mm, and the length (height) in the vertical direction is 20 to 70 mm. In particular, the thickness is preferably 25 to 50 mm. In addition, when a part or all of the fastening tape 13 has a substantially tapered shape, for example, and the length in the vertical direction and the length in the width direction are not constant, the numerical range is determined by an average value. The fastening tape 13 may have a symmetrical shape such as a rectangular shape. However, if the fastening tape 13 is a convex shape composed of a wide attachment portion and an elongated tip side portion, the grip portion on the tip side portion can be easily picked and This is preferable because the tension between the bases of this region acts over a wide range. The hook member 13A has a large number of engaging protrusions on the outer surface side. The shape of the engaging protrusion is (A) Le-shaped, (B) J-shaped, (C) Mushroom-shaped, (D) T-shaped, (E) Double J-shaped (J-shaped And the like may be any shape. Instead of the hook material 13 </ b> A, an adhesive material layer can be provided as a locking portion of the fastening tape 13.

  When wearing the diaper, as shown in FIG. 7, the fastening tape 13 is placed on the outer surface of the back portion B with the side flap portion SF of the abdominal portion F overlapped on the outside of the side flap portion SF of the back portion B. Lock in place. The position and size of the fastening portion of the fastening tape 13 can be arbitrarily determined. In a normal case, the locking location is a rectangular range of 20 to 80 mm in the vertical direction and 150 to 300 mm in the width direction, the distance in the height direction between the upper edge and the ventral upper edge is 0 to 60 mm, particularly 20 to 50 mm, And it is preferable to set it as the center of the width direction of a product.

  When the fastening tape 13 is attached so that its attachment portion overlaps the ventral side edge of the absorbent element 50 in the longitudinal direction, the absorbent element 50 is applied by tension acting between the attachment portions of the left and right fastening tapes 13 when the diaper is attached. This is preferable because the ventral end portion is firmly pressed against the body. Moreover, if the attachment part of the fastening tape 13 is too far from the ventral end part (rear end part) of the diaper, the tension acting between the attachment parts of the left and right fastening tapes 13 when the diaper is mounted is the ventral end part of the diaper. Therefore, a gap is easily generated between the ventral end of the diaper and the body surface. Therefore, it is preferable that the longitudinal length of the end flap EF in the ventral portion F is equal to or shorter than the longitudinal length of the base portion of the fastening tape 13. From this viewpoint, the longitudinal length of the end flap EF in the ventral portion F is preferably about 5 to 20% of the total length L of the diaper, and is particularly preferably 10 to 60 mm, particularly 20 to 50 mm. .

(Target sheet)
It is preferable to provide a target sheet 12T having a target for facilitating the locking at the locking portion of the fastening tape 13 in the back portion B. As the target sheet 12T, when the hook portion is the hook material 13A, a target sheet 12T can be used in which a large number of loop yarns are formed on the surface of a sheet base material made of a plastic film or nonwoven fabric so that the hook material engagement protrusions are entangled. In the case of an adhesive material layer, a sheet base material made of a plastic film having a smooth surface that is rich in adhesiveness can be used.
Further, when the fastening portion of the fastening tape 13 in the back portion B is made of a nonwoven fabric, for example, when the exterior sheet 12 of the illustrated form is made of a nonwoven fabric, and the fastening portion of the fastening tape 13 is a hook material 13A. Can omit the target sheet 12T and entangle the hook material 13A with the nonwoven fabric of the exterior sheet 12 to be locked. In this case, the target sheet 12T may be provided between the exterior sheet 12 and the liquid-impermeable sheet 11.

(Wrapping part and tail through part)
Characteristically, at the end of the back portion B on the main body portion 10 side, a belt-like winding that includes a portion facing the root of the tail 100 and extends to the sides of the width direction so as not to reach both side edges. A partial formation region 70 is provided, and a winding portion is formed except for an uncut portion (width direction central portion) 71 facing the anus-side edge at the root of the tail 100 in the periphery of the winding portion formation region 70. A perforation 72 is formed. In use, as shown in FIG. 7, the winding portion forming perforation 72 is cut off as necessary to form a winding portion 80 that is continuous from the edge along with the tail threading portion 81. Furthermore, in this example, a slit forming perforation 73 extending along the center line in the width direction from the winding portion forming perforation 72 to the other edge in the longitudinal direction is also provided. Accordingly, as shown in FIG. 8, by separating all the slit forming perforations 73, the back portion B can be divided into left and right sides.

  In addition, a connecting means 74 for connecting to the other end is provided at one end in the width direction of the winding portion forming region 70. As the connecting means 74, a pressure-sensitive adhesive layer or a hook sheet (also referred to as a male material) of a mechanical fastener (surface fastener) can be suitably used. In the latter case, a loop sheet of a mechanical fastener (a sheet provided with a number of loops on the surface, also referred to as a female material) may be attached to the other end of the wound portion forming region 70. When it is formed of a material that can be engaged with a hook sheet (male material) of a mechanical fastener like a nonwoven fabric, it can be engaged with the material. The connecting means 74 is preferably provided on the outer surface of the diaper, but can also be provided on the inner surface.

  In use, as shown in FIG. 7, the user cuts the winding portion forming perforations 72 as necessary to form the tail through portion 81 and the winding portion 80, and the winding portion 80. A state in which the base portion 82 is aligned with the edge of the anus at the base of the tail 100 and the flap portions 83 extending on both sides in the width direction of the base portion 82 of the winding portion 80 are wound around the tail 100 as shown in FIG. Thus, the winding portion 80 is fixed in a cylindrical state having an arbitrary diameter by the connection of the connecting means 74. Thereby, the part which coat | covers an anus and its circumference | surroundings is supported by the tail 100 via the winding part 80 which continues from there, and becomes difficult to slide down. Therefore, it is possible to form the tail-through part 81 and the winding part 80 as necessary with a simple and easy-to-manufacture structure in which a perforation is made in a predetermined pattern without requiring a separate member. In addition, it is possible to make it difficult to create a gap between the tail-through portion 81 and the anal-side edge at the base of the tail 100, thereby preventing leakage of excrement from the tail-through portion 81. It becomes like this.

  As shown in FIG. 9 (a), the connecting portion 74 by the connecting means 74 may be overlapped and connected in the form of a palm as shown in FIG. 9 (b). it can. In any case, the cylindrical portion formed of the winding portion 80 can have a diameter matching the tail 100.

  Further, as shown in FIG. 10, the slit-forming perforations 73 are all cut off when mounting, so that the back portion B is divided into left and right sides, and the portions on both sides of the slit are passed through the both sides of the tail 100 to the front of the tail 100. And fasten the fastening tape 13 on the left side of the ventral part F to the right side of the dorsal part B and fix the fastening tape 13 on the right side of the ventral part F to the left side of the dorsal part. In this case, not only the difficulty of passing the tail 100 through the conventional tail hole is improved, but also there is an advantage that it is possible to cope with various kinds and sizes of pets. .

  The shape of the winding portion 80 may be designed as appropriate. For example, a rectangular shape is preferable from the viewpoint of ease of manufacturing and preventing generation of trim (end material), but there is a possibility that the movement of the tail 100 to the back side may be hindered. Alternatively, there is a possibility that unnecessary wrinkles may come to the winding portion 80 in the vicinity of the root of the tail 100. Therefore, as shown in FIG. 11, one side in the longitudinal direction of the winding portion 80 (in FIG. 11, since the perforation 72 is not cut off, the winding portion forming region 70 corresponds to this. Reference numeral 80 refers to FIG. 7). A form is also proposed in which the abdominal side edge 75 is formed in a shape toward the other side in the longitudinal direction as it goes outward in the width direction. It is preferable that the edge 76 on the other side (back side) in the vertical direction has the same shape. If it has such a shape, the movement of the tail 100 is hardly obstructed, and unnecessary wrinkles are less likely to lean.

  Although the dimension of the winding part 80 can be designed suitably, in normal cases, the longitudinal length is preferably about 3 to 40% of the total length L of the diaper, and the width is about 30 to 75% of the total width X of the diaper. Is preferable. Although the dimension of the base part 82 located in the center of the width direction and the flap part 83 extending symmetrically on both sides thereof can be determined as appropriate, the width of the base part 82 is about 5 to 50% of the total width X of the diaper. The width (one side) of the flap portion 83 is preferably about 3 to 40% of the total diaper width X.

  In the wearing state shown in FIG. 7 and the examples shown in FIGS. 12 and 13 described later, since an open part is formed on the tail 100 side of the main body part 10, there is a possibility that excrement may leak from this part. Therefore, as shown in FIGS. 1 and 6, the root portion 82 of the winding portion 80 (the winding portion forming region 70 corresponds to the winding portion 80 because it is before the perforation 72 is cut off in FIGS. 1 and 6). The uncut portion 71 corresponds to the root portion. Reference numerals 80 and 82 refer to FIG. 7.) In the vicinity of one side in the longitudinal direction, a tail through portion leakage preventing three-dimensional gather 90 protruding from the surface along the width direction. By extending, it is also a preferable form to effectively prevent leakage from the gap of the tail passage portion. The tail through-hole leakage prevention three-dimensional gather 90 in the illustrated example is a belt-shaped gather sheet 91 extending in the width direction so as to straddle between the side three-dimensional gathers 60, and the crotch side end of the gather sheet 91 along the width direction. And an elastic elastic member 92 fixed in an extended state. The gather sheet 91 and the elastic elastic member 92 in the tail through-hole leakage preventing three-dimensional gather 90 can be selected from the same materials as the gather sheet 62 and the elastic elastic member 63 in the side three-dimensional gather 60. And as for the width direction both ends which overlap the non-stand-up part (end part by the side of the winding part 80) of the side part three-dimensional gather 60 in the gather sheet | seat 91, the whole vertical direction is joined to the surface of the side part three-dimensional gather 60, and these Of the intermediate portion in the width direction, the end on the winding portion 80 side is joined to the surface of the topsheet 30, and the crotch portion is not fixed to the topsheet 30, but is a free portion. The elastic elastic member 92 stands up due to the contraction force. These joining portions are indicated by hatching in FIG. 1, and can be formed by joining means such as a hot melt adhesive. In this example, the through-hole leakage preventing three-dimensional gather 90 is provided on the side three-dimensional gather 60, but may be provided between the side three-dimensional gather 60 and the top sheet 30.

  On the other hand, when the amount of hair of the tail 100 is large, or when the movement of the tail 100 is large, the winding portion 80 may be displaced, loosened, or detached. Therefore, it is also a preferred form that the winding portion 80 is configured to elastically expand and contract in the width direction. As a result, when the winding part is wound around the tail 100 to form a cylinder, the cylindrical winding part fits the tail 100 by elastically tightening the tail 100. It will be able to handle a wide variety of pet types and dimensions, such as being difficult to slip. In order to make the winding portion elastically expand and contract in the width direction, for example, an elastic expansion and contraction sheet such as a rubber sheet may be attached to the winding portion forming region 70 in a state of extending in the width direction. When the formation region 70 has a laminated structure of a plurality of sheets, the elastic elastic member 84 is arranged between the sheets (between the exterior sheet 12 and the liquid-impermeable sheet 11 in the illustrated example). It is preferable to clamp and fix in an extended state. The elastic expansion / contraction member 84 may be a non-porous rubber sheet. However, in terms of air permeability, the elastic expansion / contraction member 84 is of an elongated shape such as a thread shape or a string shape (illustrated example), a mesh shape, or a porous sheet shape. Is preferred.

(Other)
(A) In the above example, the tail part is formed by the winding part forming perforations 72, and the slit is formed by the slit forming perforations 73, but holes and slits are previously formed as in the prior art. May be.
(B) Unlike the above example, as shown in FIGS. 12 and 13, a configuration in which the dorsal portion and the tail-through portion are omitted may be employed. In the example shown in FIGS. 12 and 13, only the winding portion forming region 170 is provided on the other longitudinal side of the main body portion 10, and the central portion in the width direction is cut out of the boundary between the main body portion 10 and the winding portion forming region 170. A winding portion forming perforation 172 is formed over the entire widthwise sides of the remaining portion 171. Moreover, it is comprised so that it may connect with the fastening tape 113 and the target sheet | seat 112T by turning to one side part of the main-body part 10, the other side part, and the back side of a pet. In this embodiment, as shown in FIG. 13, the ventral portion F of the main body portion 10 is formed into a cylindrical shape with a fastening tape 113 and supported by being wound around the body portion, while the winding portion forming perforation 172 is separated and wound. A portion 80 is formed, the root portion 82 of the winding portion 80 is aligned with the anal side edge at the root of the tail 100, and the flap portions 83 extending on both sides in the width direction of the root portion 82 of the winding portion 80 are formed on the tail 100. In this state, the winding portion 80 is fixed in a cylindrical state with an arbitrary diameter by the connection of the connecting means 174, so that the buttock covering portion M is supported by the tail 100. This form has the advantage that the amount of material used can be suppressed, and there are many exposed portions that are not covered by the diaper, resulting in excellent breathability.

  The present invention is not limited to the stationary type as in the above example, and can be used for all disposable diapers for pets such as a pants type.
