いた。However, in the conventional napkin, since the elastic deformation of the napkin is too strong, the napkin cannot conform to the body shape of the user, side fluid leaks, and the amount of the elastic body used is inadequate. It had a drawback that it was made uneconomical by increasing the amount required.

また、特に弾性体が複数本の場合、弾性体の止着不良が
多くなって、不良品の発生率が多くなり、生産性が低下
する虞れがあった。The napkin is manufactured by a production line that moves at a high speed. However, since the elastic body is directly attached to both sides of the narrow napkin on the production line, the elastic body is not formed. It was likely to cause improper fastening.
Further, particularly when there are a plurality of elastic bodies, there is a possibility that the number of defective fixing of the elastic bodies increases, the incidence of defective products increases, and the productivity decreases.

After that, on the surface sheets on both sides of the absorbent layer, fold the thermoplastic non-woven fabric in two and place the two side pieces whose folds are located on the side of the absorbent layer, and the both side pieces are 1 to 10 elastic bodies. A clamping piece that is clamped and fixed at a stretch ratio of 1.2 to 2.0 times is located in the length direction, and an elastic body is formed on this clamping piece 40% of the total length of the napkin body for the purpose.
Use the one fixed in advance with a length of -60%, and the both sides of the piece placed on the surface sheet, the start-up allowance from the folding part is 5 mm to 20 m.
As m, the base end is heat-welded to the top sheet and the both side pieces, the top sheet and the leakproof sheet are fixed together, and then both ends of the napkin body are cut together with the topsheet, the leakproof sheet and both side pieces. It is characterized by what you do by doing.

A sandwiching piece that is sandwiched and fixed with a length of 40% to 60% of the entire length of the napkin main body for molding is located on the surface of the thermoplastic nonwoven fabric, and this thermoplastic nonwoven fabric is folded back to sandwich the sandwiching piece, Place both side pieces on both sides of the water-permeable surface sheet that should cover the surface of the absorbent layer, with the folds inside, and fix the outer base ends of both side pieces to the surface sheet. After fixing it, the start margin from the folded part of both side pieces is set to 5 mm to 20 mm, and then this side sheet is fixed to both sides with a surface sheet,
After covering the absorbent layer located on the surface of the leakproof sheet and heat-sealing the topsheet, the leakproof sheet, and both side pieces, both ends of the napkin body are covered together with the topsheet, the leakproof sheet, and both side pieces. It is characterized by the fact that it is carried out.

出された体液の殆どは、吸収層によって吸収される。Since the present invention is configured as described above, when the napkin is brought into contact with the local area of the user, the absorbent layer is located locally through the surface sheet. Most of the body fluid discharged from the user is absorbed by the absorbent layer.

【００１６】また、ナプキンは、ナプキン本体の長さ方

形成できる。Further, the napkin has two side pieces formed by folding a thermoplastic nonwoven fabric into two on both sides in the length direction of the napkin body. The both side pieces have the folded portion of the two folds located on the absorbent layer side, and the base end portions thereof are fixed to the side flaps. If formed in this way, a rising margin can be formed in the interval between the fastening portion and the folding portion.

生的な装着が可能となる。Further, the both side pieces fix the sandwiching pieces to which the elastic body is fixed in the longitudinal direction. Therefore, the both side pieces are urged in the contraction direction by the contraction of the elastic body, so that the rising margins rise on both sides of the absorbent layer. Therefore, even if the bodily fluid is diffused in the width direction of the absorption layer, the bodily fluid is stopped by the both side pieces positioned higher than the absorption layer, and the lateral leakage of the bodily fluid can be prevented. In addition, the both side pieces can retain body fluid in the space between the start-up allowance and the absorption layer, obtain a large side leakage prevention effect, and can be mounted hygienically.

害を生じる。Further, both side pieces have a rising margin between the fastening portion for fastening the base end portion and the folding portion of 5 mm to 20 mm. If formed in this way, the side pieces can prevent lateral leakage of body fluid with a natural feeling of use without giving the user a feeling of strangeness. If both sides are formed with a start margin of less than 5 mm, the start width is insufficient and side leakage is likely to occur. If both sides are formed with a start-up allowance of more than 20 mm, and if this start-up part falls sideways on the side of the absorption layer, the absorption layer is covered with both-side pieces of large area, Impairs fluid absorption.

性体の収縮力が大き過ぎて、柔軟に伸張せず、ナプキン
本体の反り返りが大き過ぎるものとなる。Further, the both side pieces are internally fixed with a sandwiching piece having 1 to 10 elastic bodies fixed in a stretched state. If formed in this way, the both side pieces do not impair the contraction force even when the user exercises or the like, and the both side pieces can be reliably started up. Further, the both side pieces cannot obtain a contracting force at all unless the elastic body is fixed to the sandwiching piece, which makes it difficult to start up. If more than 10 elastic bodies are fastened, the contraction force of the elastic body is too large, and the elastic body does not expand flexibly, and the warp of the napkin body becomes too large.

ものとなる。Further, as both side pieces, a sandwiching piece having an elastic body fixed at a stretch ratio of 1.2 to 2.0 is fixed in the lengthwise direction. When formed in this way, the elastic body can obtain an appropriate contraction force, and the two side pieces can be appropriately raised. Further, in the case of the both side pieces, if the expansion ratio of the elastic body fixed to the sandwiching piece is less than 1.2, the contracting force becomes insufficient and it becomes difficult to start up the both side pieces.
Further, if the elastic body is fixed at an extension rate exceeding 2.0, the contraction force increases and the warp of the napkin body becomes too large.

ものとなる。Further, the both side pieces are formed such that the length of the fixing portion of the elastic body is 40% to 60% of the total length of the napkin body for molding. When formed in this manner, the contraction range of the elastic body is optimized with respect to the entire length of the napkin body, and the napkin can be three-dimensionally formed according to the body shape of the user. In addition, if the elastic body is formed so that the length of the fixing part is less than 40% of the total length of the napkin body for molding, the range length of the elastic body will be short, and the napkin will match the user's body shape and Difficult to form. If the elastic body is formed so that the length of the fixing portion exceeds 60% of the total length of the napkin main body for molding, the elastic body has a large contraction range,
The warp of the napkin becomes excessively strong, which deteriorates the feeling of use and increases the amount of elastic body used, which is uneconomical.

If it is formed of any one of the thermoplastic elastomers, it becomes possible to inexpensively and easily manufacture an elastic body having a large stretching force.

It can be fitted and fixed integrally to the crotch part, and will not slip even if it is subjected to intense exercise, etc., and stable mounting that prevents twisting, twisting, etc. becomes possible.

Further, even when the diffusion of the bodily fluid is intense, the leak preventive film prevents the passage of the bodily fluid, and the lateral leakage of the bodily fluid can be prevented.
