[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a tape-type disposable paper diaper that is excellent in air permeability in the crotch part and the crotch surrounding part that are most likely to be steamed, and that is excellent in fit and wearing feeling.
[0002]
[Prior art]
Conventionally, as shown in FIG. 8, a disposable diaper provided on the market has a liquid-impervious backsheet 1A made of polyethylene or the like arranged on the back surface side, and a permeable cloth made of nonwoven fabric or the like arranged on the surface side. It is mainly composed of a liquid top sheet 2 and an absorbent body 3 disposed between the liquid-impervious back sheet 1A and the liquid-permeable top sheet 2, and is provided on the surface side at both sides of the paper diaper. A three-dimensional gather BS standing up on the surface side is formed by the three-dimensional gather sheet 4 made of a nonwoven fabric and the like, and an elastic stretchable member 5 disposed along the inner edge thereof, and the side edges of the absorbent body 3 A side flap portion SF not including the absorber 3 is formed by the liquid-impervious backsheet 1 </ b> A portion that extends to the side more than the outer sheet portion of the three-dimensional gather sheet 4, and these Plural rows of thread-shaped elastic rubber 7, 7 is by being arranged along the longitudinal direction of the disposable diaper, pleated flat gathers are formed on the side flap portions SF in between.
[0003]
[Problems to be solved by the invention]
In the case of the conventional paper diaper structure described above, the side flap portion SF has a multi-layer structure of a liquid-impermeable back sheet 1A such as polyethylene and a three-dimensional gather sheet 4 made of nonwoven fabric, etc. The lack of breathability around the hips and crotch, the stuffiness was severe when worn for a long time, especially in summer, which caused sweats and eczema. In addition, the polyethylene sheet having relatively low flexibility has a problem that it is difficult to fit softly in the crotch part and the crotch part, and the wearer feels a feeling of stickiness.
[0004]
On the other hand, when examining the absorbent body 3 from various angles, the absorbent body 3 is required to have a target urine absorption capacity. In order to increase the urine absorption capacity, the area of the absorbent body 3 is increased. When it is increased, it has been found that problems occur such that the wearing feeling is impaired when the legs are in contact with the absorbent body 3 having rigidity in the wearing state of the disposable diaper.
[0005]
Therefore, the first main problem of the present invention is to ensure high breathability in the waist and crotch area to prevent stuffiness and skinnyness, and to eliminate the feeling of wrinkles around the waist and crotch and to improve the fit and fit. Etc.
[0006]
In addition to the first problem, the second problem is to reduce the hitting of the leg by the absorbent body while having a sufficient urine absorption capacity as a whole.
[0007]
[Means for Solving the Problems]
In order to solve the first problem, the present invention covers the use surface side, an absorbent body is interposed between a liquid-permeable top sheet made of nonwoven fabric and a back sheet covering the outer surface side, and both sides of the paper diaper. with three-dimensional gathers are formed protruding on the surface side over substantially the diaper entire length part, the nonexistent flap portion of the absorbent body in the longitudinal end and side portions of the absorbent body is formed, and the back-side side edge portions In a tape-type disposable paper diaper in which a fastening tape for installation is arranged ,
The back sheet is composed of a non-woven fabric, and a waterproof film is interposed in a range substantially covering the absorber between the absorber and the back sheet, and only the non-woven fabric is configured in the entire peripheral region outside the waterproof film. Forming the flap part,
In the back side end portion and the ventral side end portion of the paper diaper, the waterproof film is slightly extended from the upper and lower edges of the absorbent body, superposed on the extended portion of the waterproof film, and over the entire width of the diaper, An intermediate non-woven fabric is interposed between the back sheet and the liquid-permeable top sheet, and at least at the back end of the paper diaper, between the intermediate non-woven fabric and the back sheet, spaced in the vertical direction of the paper diaper, along the width direction. A plurality of thread-like elastic rubber to form a back elastic band,
The tape-type disposable paper diaper is characterized in that a base portion of the fastening tape is fixed to both end portions of the dorsal elastic band forming region . In this case, it is desirable that the width of the back side elastic band in the elastic band is in the range of 50 to 100 mm, and the width of the ventral side elastic band is 20 to 50 mm.
[0008]
The first example that can be cited as a structural example of the side flap portion of the absorbent body side is formed by extending the waterproof film slightly laterally from both side edges of the absorbent body, and the liquid-permeable top sheet. Fixed to the side edge,
The width direction intermediate part of the nonwoven fabric sheet which forms the said three-dimensional gathers adheres along the longitudinal direction of a diaper in a paper diaper side part, and it extends to the side beyond the said liquid permeable top sheet side edge part. The non-woven sheet portion and the back sheet that extends laterally beyond the waterproof film side edge portion form a side flap portion that does not have an absorber, and an elastic elastic member is disposed between the sheets to form a flat gather It is characterized by forming.
[0009]
In the second example, the waterproof film is formed so as to extend slightly laterally from both side edges of the absorbent body, and is fixed to the liquid-permeable top sheet surface, and the liquid-permeable top sheet is attached to the waterproof film. While extending to the outline position of the paper diaper beyond the fixed part, it is fixed to the back sheet,
The width direction intermediate part of the nonwoven fabric sheet forming the three-dimensional gather is fixed along the longitudinal direction of the diaper at the side of the paper diaper, and the three-dimensional gather is formed at an inner part of the fixed part, and more than the fixed part. The outer portion is folded back twice, and a plurality of thread-like elastic rubbers are arranged inside the double sheet to form a standing stretchable band. In these cases, it is desirable to use a water-repellent treated non-woven fabric as the non-woven fabric sheet forming the side flap portion in terms of touch to the skin.
[0010]
On the other hand, in the present invention for solving the second problem in addition to the first problem, in the disposable paper diaper, the absorbent body has a constricted portion in which both side edges are constricted inward at the crotch portion. The upper crepe paper that covers the upper surface side and extends laterally beyond the absorber side edge and the lower crepe paper that covers the lower surface side of the absorber and extends laterally beyond the absorber side edge are included. In addition, a side body fluid absorption region by the crepe paper layer is formed by a laterally extending portion of the upper layer crepe paper and the lower layer crepe paper, and the crepe paper layer is spaced apart from the side edge of the absorber at least in the crotch portion of the paper diaper. The three-dimensional gather is formed with the inside of the side body fluid absorption region section as a standing end. In this case, the upper-layer crepe paper and the lower-layer crepe paper are folded back with the extended end portion on one side overlapped with the extended end portion on the other side at the outermost edge portion to form a superposed portion of the crepe paper. It is desirable.
[0011]
In the present invention, instead of the conventional flap structure constituted by a laminated sheet of a liquid-impermeable back sheet (plastic sheet) and a nonwoven sheet, the end flap part and the side flap part, that is, the entire circumference of the paper diaper It is made up of only non-woven fabric. Accordingly, since there is no liquid-impervious plastic film around the waist and crotch where sweat is most likely to occur when worn, the air permeability of the part is greatly improved. In addition, since there is no plastic sheet that is relatively inflexible, the feeling of sticking is lost, and the feeling when worn is excellent. Furthermore, since the waterproof film is used only in the minimum necessary area, the amount of use is reduced and the cost can be reduced.
[0012]
In addition, at least at the front and rear ends of the paper diaper, a plurality of thread-like elastic rubbers are arranged along the width direction at intervals in the longitudinal direction of the paper diaper so as to form an elastic band (shearing). In addition, the wearability of the disposable diaper does not occur when worn, and the wearability is excellent. Furthermore, in the case of the second example of the side flap portion, instead of the conventional flat gathers, a standing stretchable band, so-called pleated standing gathers are formed, so that the skin is surely linear or planar. It comes into contact and can reliably prevent side leakage.
[0013]
On the other hand, the crepe paper containing the absorbent body extends from the side edge of the absorbent body to the side, and by forming a three-dimensional gather with the crepe paper layer as an upright end, while having sufficient urine absorption ability as a whole The area of the absorbent body can be reduced, and the rigid absorbent body can be prevented from strongly hitting the leg, and the wear feeling and fit can be improved.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
[0015]
[First embodiment]
FIG. 1 is a partially broken development view of a disposable diaper according to the present invention, and FIG. 2 is an enlarged development view of the main part of FIG.
[0016]
In FIG. 1, the disposable paper diaper is made of a perforated or non-porous nonwoven fabric and covers a liquid-permeable top sheet 2 that covers the use surface side, and the nonwoven fabric covers the outer surface of the paper diaper. And the side flap portion SF, and the back sheet 1 that forms the end flap portion EF together with the liquid-permeable top sheet 2 at the front and rear ends of the diaper, and the liquid-permeable top sheet 2 and the back sheet 1 are interposed The absorbent body 3 made of cotton-like pulp or the like and having a certain degree of rigidity, such as an hourglass shape (or rectangular shape), and substantially covers the absorbent body 3A between the absorbent body 3 and the back sheet 1 A waterproof film 9 made of polyethylene or the like disposed in the range and a three-dimensional gather BS standing on the surface side on both sides of the disposable diaper are formed. In both side portions it is mainly composed of standing gathers nonwoven 4 which for constituting the side flaps SF together with the back sheet 1.
[0017]
The absorbent body 3A has an hourglass shape as a whole, but when the standing end position of the three-dimensional gather BS is taken as a reference, the side edge of the absorbent body 3A is not located outward from the standing end position, and the area of the absorbent body Reduction is being achieved. That is, the constricted portions 3a and 3a are formed so as to have a side edge on the inner side of the base end position of the three-dimensional gather BS in a portion corresponding to the crotch of both side edges based on a rectangular shape rather than an hourglass shape. . The absorbent body 3A is encapsulated by the crepe paper 18.
[0018]
As shown in detail in FIGS. 2 and 3, the crepe paper 18 has a rectangular upper crepe paper 18 </ b> A that extends laterally beyond the upper surface of the absorber 3 </ b> A and the side edge of the non-constricted portion 3 a, It comprises a lower layer crepe paper 18B having a rectangular shape that extends laterally beyond the lower surface of the absorbent body 3A and the non-constricted portion 3a side edge. In the example, the extended end of the lower crepe paper 18B is overlapped with the extended end of the other crepe paper (upper layer crepe paper 18A in the illustrated example) and folded to form a superposed portion of the crepe papers 18A and 18B.
[0019]
Further, the crepe paper 18A, the side body fluid absorbent region P _S according 18B layer is formed by lateral extending portions of the upper crepe paper 18A in site crotch (constricted portion 3a forming portion) and the lower crepe paper 18B, stereoscopic gathers BS are formed an absorber 3A side edges laterally spaced from and the crepe paper 18A, the side body fluid absorbent region P _S in the interval by 18B layer as standing ends.
[0020]
The advantages of this absorber configuration are as follows. That is, first, since the absorber 3A is wrapped by the upper and lower crepe papers 18A and 18B, the absorber 3A does not protrude at least outward in the width direction.
[0021]
Second, even if the width of the absorber 3A is narrowed, the urine absorbability is ensured in the width region (side body fluid absorption region P _S ) where the upper layer and lower layer crepe papers 18A and 18B exist. However, in the portion where only the upper upper layer and the lower layer crepe paper 18A, 18B on the outer side of the constricted portions 3a, 3a are present, the portion that hits the leg is easily deformed because it is not rigid and easily deformable. The wearing feeling is improved, and the absorber 3A has the constricted portion 3a, so that the degree of freedom of movement of the legs is large and a good fit is exhibited.
[0022]
Third, as can be seen from FIG. 2, since the standing end of the three-dimensional gather BS is formed away from the side edge of the absorbent body 3A in the crotch portion, this constricted portion 3a becomes a temporary pocket for blocking soft stool. The urine is diffused mainly in the upper crepe paper 18A among the upper and lower crepe papers 18A and 18B, and the urine diffused in the middle in the width direction or in the longitudinal direction is eventually absorbed by the absorber 3A. .
[0023]
Thus, since it is not necessary to position the standing end of the three-dimensional gather BS within the width of the absorber 3A as in the prior art, the standing end of the three-dimensional gather BS can be positioned more outward, and as a result, The spacing between the free ends of the three-dimensional gather BSs on both sides can be increased, so that urine and loose stool can be reliably captured even if the wearer moves excessively in the width direction.
[0024]
On the other hand, in this example, the back sheet 1 made of a nonwoven fabric is used instead of the liquid-impermeable back sheet 1A (see FIG. 8) made of polyethylene or the like that is usually used to cover the outer surface of the diaper. In order to prevent the body fluid absorbed by the body 3 </ b> A from oozing out to the outer surface side, a waterproof film 9 made of polyethylene or the like is interposed between the absorber 3 and the back sheet 1.
[0025]
The waterproof film 9 has a rectangular shape in a range covering the absorbent body 3A, and both side edges are formed to extend slightly laterally from the side edges of the absorbent body 3 (this portion is a side extending portion K). that _S.), it is fixed by such liquid-pervious top sheet 2 and the hot melt adhesive in this side extending portion K _S. Moreover, the said back sheet 1 is laminated | stacked on the outer surface side of the said waterproof film 9, is extended to the position which comprises the outline of a paper diaper, and forms the side flap part SF with the solid gathering nonwoven fabric 4 mentioned later.
[0026]
In recent years, a film having moisture permeability is preferably used as the waterproof film 9 from the viewpoint of preventing stuffiness. This water and moisture permeable sheet is a microporous sheet obtained by, for example, melt-kneading an inorganic filler in an olefin resin such as polyethylene or polypropylene to form a sheet, and then centrifuging in a uniaxial or biaxial direction. If the sheet thickness is the same, the rigidity is lower than that of the non-porous sheet, which is superior in terms of flexibility.
[0027]
On the other hand, standing gathers nonwoven 4, the width direction intermediate portion in the region spanning absorber 3 side edges from lateral extending portion K _S is fixed along a substantially longitudinal direction of the paper diaper, the side than the fixing portion The extending nonwoven fabric sheet portion constitutes a side flap SF composed of only the nonwoven fabric together with the backsheet 1. In the side flap portion SF, a plurality of elastic stretch members 7, 7 in the illustrated example are arranged between the three-dimensional gathered nonwoven fabric 4 and the back sheet 1 in the longitudinal direction of the paper diaper. Is formed. This flat gather GK holds the paper diaper tightly around the legs when worn, thereby improving fit and preventing the paper diaper from shifting. In addition, when the paper diaper is held tightly, the three-dimensional gather BS is mounted upright along the legs without turning over.
[0028]
On the other hand, a three-dimensional gather BS standing on the surface side is formed by a non-woven fabric sheet portion on the inner side of the fixed portion of the three-dimensional gathered nonwoven fabric 4. This three-dimensional gather BS has a standing end near the side edge of the absorbent body 3, and the tip thereof is double-folded along the longitudinal direction of the paper diaper, and one thread-like elastic rubber 5 is placed inward of the folded portion. Or, if necessary, a plurality of thread-like elastic rubbers are provided to make the three-dimensional gather BS stand up by utilizing the stretching force. As the thread-like elastic rubber 5, materials such as styrene rubber, olefin rubber, urethane rubber, ester rubber, polyurethane, polyethylene, polystyrene, styrene butadiene, silicon, and polyester that are usually used can be used.
[0029]
The material fibers constituting the back sheet 1, the liquid-permeable top sheet 2 and the three-dimensional gathered nonwoven fabric 4 include olefin-based, polyester-based, and amide-based synthetic fibers such as polyethylene or polypropylene, as well as rayon and cupra. Recycled fibers, natural fibers such as cotton can be used, and nonwoven fabrics obtained by appropriate processing methods such as the spunbond method, thermal bond method, melt blown method, needle punch method, etc. can be used. As the three-dimensional gathered non-woven fabric 4 and the back sheet 1 constituting SF, it is preferable to use a non-woven fabric excellent in air permeability by suppressing the basis weight in order to eliminate the feeling of gore and prevent stuffiness. In order to obtain a nonwoven fabric satisfying the air permeability, a nonwoven fabric prepared with a basis weight of approximately 18 to 23 g / m ² is preferably used.
[0030]
In this disposable paper diaper, the side flap portion SF is made of a non-woven fabric, so that the portion has liquid permeability, but the liquid permeability is reduced as much as possible to prevent the passage of body fluids and to prevent fogging. In order to improve the touch to the skin (dry feeling), it is desirable to use a water-repellent non-woven fabric coated with a silicon-based, paraffin metal-based, alkylchromic croid-based water repellent or the like.
[0031]
On the other hand, on the back side of the paper diaper, as shown in FIG. 4, the waterproof film 9 is slightly extended from the upper and lower edges of the absorbent body 3 </ b> A, and the back sheet 1 and the transparent sheet are formed in the outer region of the waterproof film 9. An end flap portion EF is formed by the liquid top sheet 2 and the intermediate nonwoven fabric 10 interposed between the nonwoven fabric sheets 1 and 2, and the intermediate woven fabric 10 and the backsheet 1 are spaced in the longitudinal direction of the paper diaper. A plurality of thread elastic rubbers 11, 11... In the illustrated example are arranged along the width direction to form an elastic band 8 </ b> A. The intermediate nonwoven fabric 10 has a role of disposing and fixing the thread-like elastic rubbers 11 between the back sheet 1 and the back waist portion before the liquid-permeable top sheet 2 is stretched in the manufacturing process. It contributes to improving the feeling of wearing by having it.
[0032]

More specifically, stretching the thread-shaped elastic rubber 11, 11 ... interval with a range of 3 to 20 mm, expansion ratio 150 to 250% elastic strength as 50 to 400 g, in the range of the width _{W B} It is desirable to constitute the band 8A.
[0033]
On the other hand, for the ventral side of the disposable diaper, it is the same configuration except for the difference in the width dimension W _F. Specifically, as shown in FIG. 5, without extending the waterproof film 9 to the outer edge of the paper diaper, the waterproof film 9 is slightly extended from the upper and lower edges of the absorbent body 3A. An end flap portion EF is formed by the back sheet 1 and the liquid permeable top sheet 2 and the intermediate nonwoven fabric 12 interposed between the two nonwoven fabric sheets 1 and 2, and the intermediate nonwoven fabric 12 and the back sheet 1 are formed. A plurality of thread-like elastic rubbers 13, 13 in the illustrated example are arranged along the width direction at intervals in the longitudinal direction of the paper diaper so as to form the elastic band 8B.
[0034]
Width W _F of the ventral side stretchable bands. 8B, as well as ensuring the fit, it is desirable in the range of 20~50mm to reliably prevent slipping of the diaper. Stretch More specifically, the thread-like elastic rubber 13, 13 ... interval with a range of 3 to 20 mm, expansion ratio 150 to 250% and an elastic strength as 50 to 400 g, in the range of the width _{W F} It is desirable to configure the band 8B.
[0035]
[Second embodiment]
Next, the second embodiment shown in FIGS. 6 and 7 shows a modified example of the structure of the side flap portion SF.
[0036]
The waterproof film 9 is formed so as to extend slightly laterally from both side edges of the absorbent body 3 </ b> A, and is fixed to the surface of the liquid-permeable top sheet 2, and the liquid-permeable top sheet 2 is attached to the waterproof film 9. While extending beyond the fixed portion to the position of the outline of the paper diaper, it is fixed to the back sheet to form the side flap portion SF.
[0037]
An intermediate portion in the width direction of the three-dimensional gathered nonwoven fabric 4 ′ for forming the three-dimensional gather BS is fixed along the longitudinal direction of the diaper at the side of the paper diaper, and the three-dimensional gather BS is formed at an inner portion of the fixed portion. On the other hand, the outer portion of the fixed portion is folded back twice, and a plurality of, in the illustrated example, four thread-like elastic rubbers 14, 14,... Has been. Note that the planar gather BK described in the first embodiment is not formed in the second embodiment.
[0038]
