Description

[0001]
[Industrial application fields]
The present invention relates to a pants combined paper diaper having a wing-shaped misalignment prevention means.
[0002]
[Prior art]
In recent years, disposable diapers that have been used are provided with barrier cuffs that stand three-dimensionally around the legs in order to effectively prevent leakage of excrement, or by elastic elastic members excreted in the vertical direction on the side of the diaper. Gasket cuffs are formed, and elastic elastic members are disposed on the waist to form gathers.
[0003]
However, in order to effectively exhibit the functions of these barrier cuffs, gasket cuffs, etc., it is necessary to effectively prevent diaper displacement. The relative position of the disposable diaper with the local area is easily shifted due to walking or exercise during use, and in such a case, the excrement is likely to leak. Therefore, it is an important issue to effectively prevent such deviation.
[0004]
Conventionally, as a means for preventing the slippage of such a paper diaper, when a paper diaper is placed in the pants, an adhesive for preventing slippage is applied to the outer surface of the outer surface side sheet (liquid-impermeable sheet) of the paper diaper, Such a shift was prevented by adhesion to the back of the pants.
[0005]
[Problems to be solved by the invention]
However, in the case of using the slip-preventing adhesive, since it must be applied in a developed state of the paper diaper, it cannot be applied at a time, resulting in poor productivity. Further, there is a problem that a material and an application process for applying the adhesive are required, and the cost is increased accordingly. Further, the effect of preventing the deviation is not sufficient.
[0006]
Accordingly, a main object of the present invention is to provide a pants combined paper diaper that effectively prevents misalignment of the paper diaper and is excellent in manufacturability and unity with the pants.
[0007]
[Means for Solving the Problems]
The present invention that has solved the above problems is as follows.
<Invention of Claim 1>

In a state where the pants are worn on a paper diaper secured to the wearer by the fastening tape, the crotch part is wrapped around and applied to the outside of the crotch part of the pant, and in the diaper by the wraparound A pants combined paper diaper, characterized in that a narrow leg portion is formed and connected by the fastening tape, and the paper diaper is fixed to the pants.
[0008]
<Invention of Claim 2>
Barrier cuffs are provided on both sides of the use surface side, and the barrier cuffs protrude to the use surface side by the contraction force of the elastic elastic member fixed to the barrier sheet, and the barrier sheet is used on the use surface side of the side flap portion. The pants combined paper diaper according to claim 1, wherein the diaper is a sheet, and a base portion of the fastening tape is fixed to the barrier sheet.
[0009]
[Action]
In the paper diaper of the present invention, an absorbent body is provided along the longitudinal direction of the paper diaper, and includes side flap portions that extend outward from both sides of the absorbent body to form both sides, and a paper diaper is provided on both sides on the back side. A fastening tape for fastening to a wearer is provided, and a middle portion in the longitudinal direction of the side flap portion wraps around and is applied to the outside of the pants.
[0010]
Therefore, the crotch portion of the pants is sandwiched by the side flaps that are applied around the outside of the pants, and the paper diaper is firmly fixed integrally. Compared with the method, the effect of preventing displacement is high.
[0011]
Usually, a paper diaper is manufactured in a square shape on a plane and then cut so that the leg portion is narrow, and finally formed into an hourglass shape. In this case, the cut portion is outside the pants. By using it as a wraparound part that is applied to and wrapping around, it is possible to easily form the wraparound part with almost no additional manufacturing process, facilitating production, and being originally discarded. Because it uses the part that is, it leads to the effective use of materials.
[0012]
In the paper diaper of the present invention, in order to fix to the pants, at the both outer edges of the side flap part, it is possible to form a wrap-around part by making a notch inward from the side edge apart in the longitudinal direction. .
[0013]
Therefore, the crotch portion of the pants is sandwiched by the wraparound portion that is applied to the outside of the pants, and the paper diaper is firmly fixed integrally. Compared with, it is highly effective in preventing displacement.
[0014]
In particular, as shown in FIG. 3, the longitudinal length LL of the folding line of the wrap-around portion _FW of the side flap portion that wraps outward from the crotch side edge of the pants 11 is the longitudinal length of the fastening tape 10. Since it is longer than L, the entire wrap-around portion _FW faces the back surface of the pants 11 and the folding line contacts the crotch side edge of the pants 11. There is no deviation due to tilt, and it is firmly fixed to the pants.
[0015]
It can also be used like a pants by first fixing a paper diaper to the pants.
[0016]
On the other hand, a barrier cuff that protrudes to the use surface side is formed on both sides of the product by the contraction force of the elastic elastic member fixed to the barrier sheet, and the barrier sheet is a constituent material of the side flap portion, and is a fastening tape. The base sheet is fixed to the barrier sheet. As can be seen immediately from FIG. 2, the barrier sheet is formed by the turning force of the wrapping part to the outer surface of the pants and the tension when the fastening tape is fastened. By tending to be pulled to the side, the use side of the barrier cuff is surely raised.
[0017]
【Example】
Hereinafter, the present invention will be described in detail based on examples.
In FIG. 1, a paper diaper is interposed between a liquid-impermeable sheet 1 made of polyethylene or the like, a liquid-permeable sheet 2 made of a nonwoven fabric, or the like, and further between the liquid-impermeable sheet 1 and the liquid-permeable sheet 2. Further, the absorbent body 3 is made of cotton-like pulp or the like, for example, a rectangular or hourglass-shaped absorber 3 having a certain degree of rigidity. In addition, elastic stretch bands 8 and 8 made of urethane foam or the like are interposed between the liquid-impervious sheet 1 and the liquid-permeable sheet 2 at the abdominal side and the back side of the edge. Fastening tapes 6 and 6 are fixed to the respective parts. The absorbent body 3 can be wrapped with absorbent paper (not shown) to maintain its shape.
[0018]
The liquid-impervious sheet 1 extends outward from the periphery of the absorber 3 to form a square, and the laterally extending portions are on the side of the barrier sheet 4 and the liquid-permeable sheet 2 described later. The side flap part F is comprised with the part. The liquid-permeable sheet 2 has a rectangular shape, and extends slightly outward from the side edge of the absorbent body 3 at the legs, and is fixed to the liquid-impermeable sheet 1 with a hot melt adhesive or the like. As a material for forming the barrier sheet 4, a plastic sheet can be used, but from the viewpoint of skin touch, a nonwoven fabric that has been subjected to a water repellent treatment with silicon or the like is preferably used.
[0019]
On the other hand, barrier cuffs B and B projecting to the use surface side are formed on both sides of the paper diaper. As shown in the figure, this barrier cuff B is formed by double folding a barrier sheet 4 that is substantially continuous in the width direction. As a result, a plurality of elastic elastic members are fixed and the barrier cuff B is erected. Further, for example, four elastic elastic members 7, 7... For gasket cuffs are fixed to the liquid-impervious sheet 1 with a hot melt adhesive or the like on the outer portion of the barrier cuff B. The barrier cuffs B and B are in contact with the wearer's legs, and form a confined space for urine or soft stool by the substantially trapezoidal space of the upper opening surrounded by the barrier cuffs B and B and the liquid-permeable sheet 2. When urinating into this space, the urine passes through the liquid-permeable sheet 2 and is absorbed into the absorbent body 3, and the barrier cuffs B and B become barriers (barriers) for the soft stool solids. The overcoming is prevented. Even if urine leaks in the lateral direction over the barrier cuffs B, B, the side leakage is prevented by the gasket cuff formed by the elastic elastic members 7, 7. Reference numeral 9 denotes a shape-retaining elastic expansion / contraction member used for forming the absorbent body 3 into a boat shape. The elastic expansion / contraction member 9 folds the absorbent body 3 having a certain degree of rigidity into a boat shape when the disposable diaper is worn. It can be held in a shape that fits the body.
[0020]
In the case of a general paper diaper, a part of the side flap portion F where the liquid-impervious sheet 1 and the barrier sheet 4 are bonded together is cut into a semi-elliptical shape, and the entire leg portion is narrowed. Although formed in an hourglass shape, in the present invention, the cut portion is used as the wraparound portion _FW .
[0021]
Specifically, after the whole is formed square by the liquid-impervious sheet 1 and the barrier sheet 4, in the side flap portion F, arc-shaped cut lines C are respectively formed on the upper and lower portions in the longitudinal direction of the paper diaper. C is inserted, and the flap portion _FW in this range can be folded back to the outer surface side as shown in FIG. 2, and in use, as shown in FIG. 3, the crotch side edge of the pants 11 to be attached to the outside of the paper diaper It turns into the outside and becomes the wraparound part _FW which is applied to the outer surface of the pants and fastened. Fixing of the wraparound portion F _W, as shown, performs the fastening tape 10 which is fixed to the flap F _W. Moreover, although not shown in figure, you may attach to a pants by sticking a slip prevention tape with respect to the pants contact surface of the said surrounding part _FW , or apply | coating an adhesive agent. Further, as the shape of the wraparound portion _FW , as shown in FIG. 4, for example, it may be formed from the side flap portion F in terms of appearance and formed into a mountain shape as shown.
[0022]
From the viewpoint of labor saving in the manufacturing process and effective use of materials, it is desirable to form the wraparound portion _FW using the cut-off portion of the side flap portion F according to the above-described procedure.
[0023]
Further, in the present invention, since it is assumed that the pants are mounted on the paper diaper, for example, as shown in FIG. 5, the slip-preventing tape 12 for bonding the pants to the liquid-impervious sheet surface side, By providing 12, the effect of preventing misalignment of the paper diaper is further improved.
[0024]
【The invention's effect】
As described in detail above, according to the present invention, it is possible to easily obtain a disposable diaper having a high displacement prevention effect without complicating the production process. Moreover, it becomes what was excellent in the integrity with pants.
