る問題点がある。The above-mentioned known technique is to prevent lateral leakage of body fluid by moving flaps in the longitudinal direction by forming flaps (wings) on both sides of the central portion. However, since it has a flat plate-like shape, it lacks in close contact with the user's body, and thus has a problem that the effect of preventing lateral leakage of body fluid is low. Further, there is a problem that the product cost becomes high due to the flap formation.

Envelops a wide and thick band-shaped absorber 2 with a non-woven fabric 3,
A waterproof sheet (for example, a P / E sheet) 5 is adhered to the clothing side P to be configured. In the embodiment, the widthwise central portion of the portion of the absorbent body 2 located on the body side Q is the nonwoven fabric 3
Instead of this, a mesh sheet 4 was used. In the conventional product, the absorbent body 2 is provided over almost the entire width of the napkin body 1. However, in the present invention, both sides of the central portion of the absorbent body 2 in the longitudinal direction are formed into an arcuate shape R, and the width Wa of the napkin body 1 is reduced. (8 cm in the example), the absorbent body 2 in the central portion in the width direction of the napkin body 1 is narrowed to have a width Wb (5 cm in the example, which is about 60% of the width Wa of the napkin body 1), and the napkin is The absorbent body 2 is provided only in the central portion in the width direction of the main body 1, and the central portions N on both side portions of the napkin main body 1 have a structure in which the absorbent body 2 does not exist, that is, the waterproof sheet 5 and the non-woven fabric 3 or are bent. The non-woven fabric 3 has two layers (see FIG. 2). The rubber thread 11 is adhered to the central portions N on both side portions of the napkin body 1 in the longitudinal direction to make the central portion N on both side portions of the napkin body 1 have a stretchable structure. In the embodiment, the rubber thread 11 is interposed between the two layers of non-woven fabrics 3 and 3,
Of course, it may be adhered to the surface of the non-woven fabric 3 or the waterproof sheet 5 (in the embodiment, the waterproof sheet 5 is used).
Cuts the central portions N on both sides of the napkin body 1 in a circular arc shape with the absorber 2. Therefore, since the non-woven fabric 3 is exposed, the rubber thread 11 is not adhered to the waterproof sheet, but is adhered only to the non-woven fabric 3). Since the rubber thread 11 is adhered to the napkin main body 1 in an expanded state, it expands and contracts in a natural state to reduce and deform both side central portions N of the napkin main body 1 to form a three-dimensional shape shown in FIG. 11. In this state, both side central portions N of the napkin body 1
Functions as a three-dimensional side guard M.

なる。Next, the first invention of the present application will be described based on the embodiment shown in FIGS. First invention is intended napkin odor having a flap 6 Te to form a telescopic structure on both sides the central portion N of Na Pukin body 1, FIG. 1
The flap 6 is added to the napkin body 1 shown in FIG. The flap 6 includes a wing portion 7 and a mounting portion 8, and the wing portion 7 is a waterproof sheet (P / E sheet) on the clothing side.
10 and the non-woven fabric 9 on the body side have a two-layer structure, and the attachment portion 8 is formed by folding back an extended part of the non-woven fabric 9 to form a two-layer structure of the non-woven fabric and bonding a plurality of thread rubbers 11 between the two-layer non-woven fabric 9. Stretchable structure. It should be noted that the waterproof sheet 10 is formed by arranging a plurality of rubber threads on the upper surface or the lower surface of the two-layer non-woven fabric 9 or by extending the waterproof sheet 10 without locating the rubber thread between the two-layer non-woven fabric 9.
Needless to say, it may be adhered. In the embodiment shown in FIG. 5, the waterproof sheet 5 is arranged outside the nonwoven fabric 3 on the clothing side and exposed, and in the embodiment shown in FIG. 6, the waterproof sheet 5 is placed on the nonwoven fabric 3 on the clothing side and the absorbent body 2. It is interposed between and. Further, in the above-described embodiment, the flap 6 has the wings 7
Is attached to the outer side of the napkin body 1 to attach the attachment portions 8 to the upper surfaces of the non-woven fabrics 3 on both sides of the central portion in the longitudinal direction of the napkin body 1, but in the embodiment shown in FIG. 7 and FIG. With the wing portion 7 facing the inside of the napkin body 1, the attachment portions 8 are bonded to the upper surfaces of the nonwoven fabrics 3 on both sides of the central portion in the longitudinal direction of the napkin body 1. In the above-mentioned embodiment of the first invention, 12 is an adhesive tape for fixing the flap 6 to clothes. Since the rubber thread 11 is adhered in the stretched state, it expands and contracts in a natural state to reduce and deform the attachment portion 8 of the flap 6 and the central portions of both side portions of the napkin body 1 to form a three-dimensional shape shown in FIG. .
