Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention relates to an absorbent article such as a menstrual napkin, a panty protector, and an incontinence guard, and more particularly to an absorbent article comprising a side flap. [Prior Art] In the case of using an absorbent article containing a side flap, the side flap portion is bent to the bottom side (the panty side), and an adhesive is fixed to the inter-turn portion of the underwear to avoid Offset. Previously, when manufacturing such an absorbent article, even a surface thin layer including a side flap shape and a bottom surface thin layer were formed by cutting the entire surface thin web and the bottom thin layer of the entire fabric, respectively. When there are extra scraps. Therefore, in recent years, the viewpoint of reducing the amount of use of the entire cloth or the amount of production of the scrap material has been considered, and the body portion having the side flap portion between the surface thin layer and the bottom surface layer is formed. A pair of side panels are formed from a whole fabric which is different from the entire thin fabric of the surface and the entire thin fabric of the bottom surface, and the pair of side panels are joined to the inner side of both side portions of the body portion to become the side flap portions. Since the side flap portion is weak in strength and is easily displaced from the main body portion, a technique has been proposed in which the joint portion between the side flap portion and the surface thin layer and the bottom surface layer is 5 mm or more. In the joint region, the joint width dimension on the surface sheet side is set to be larger than the joint width dimension on the bottom sheet side. In the above-mentioned prior art proposed, since the treatment of the positively joined side flap portion and the body portion of the present 94701.doc 1324510 is concerned, it is necessary to remarkably increase the rigidity of the side portion of the side flap portion 71. The result is 'produced. The following problem: due to the difficulty in bending the side flaps, the problem of discomfort in terms of operability, or the fact that the bent portion of the side flaps is relatively hard, causing friction or discomfort in the intercondylar portion, thereby significantly detracting from the problem of wearing feeling. Wait. The 'other' is generally a process in which the flank is rolled up into the undergarment and attached thereto to improve the prevention of creases/offsets of the absorbent article, but the flank of the above prior art is set too large Strength, which is detrimental to soft bending and fits on the underpants. Moreover, in the technique of the βHai, the surface layer is spread over the surface of the side flap portion, so that the body fluid impregnated into the surface layer oozes out and spreads over the side flap portion, and the fruit of the person has a dirty portion. The possibility of leaking and soiling the underpants. SUMMARY OF THE INVENTION An absorbent article according to the present invention includes an absorbent body, and a side flap portion is formed to extend to both sides of the absorbent body, and the absorbent body includes an absorbent body having a liquid retaining property. The surface of the absorbent body has a liquid-permeable abutting skin thin layer and a thin layer of abutting underwear covering the bottom surface of the absorbent body. The side flap portion is fixed to the abutting skin thin layer by the abutting skin side joint portion, and is fixed to the abutting back panty layer by the abutting panty side joint portion. The width of the abutting skin side joint portion is smaller than the width of the abutting back side joint portion, and the width outermost end position of the abutting skin side joint portion and the abutting back side joint portion are The outermost position of the width is more arranged on the outer side than the outermost position. 94701.doc 1324510 [Embodiment] The present invention relates to an absorbent article which has good side flap handling properties, good wrinkle, offset prevention, and good skin feel, the side flaps and the surface layer and The bottom layer is not the same. In the case of the present invention, since the width of the abutting skin side joint portion is smaller than the abutting back side joint portion, and the outermost end position of the width is disposed outside, the root portion of the side flap portion is implemented at the root portion of the side flap portion. The design that can achieve the softness of the skin on the side of the skin can be designed to ensure the strength of the flank to the extent that the flank does not fall off on the side of the abutment, and as a result, the side flap can be bent to the bottom side. Good operability, the fit of the sports shorts and the good skin feel. In the present application, the direction of the "width" is the same as the direction in which the side flaps extend. The "outermost end position" means that the abutting skin side joint portion and the abutting underwear side joint portion are located in the width direction of the absorbent article. The outermost position. Hereinafter, a preferred embodiment of the absorbent article of the present invention will be described with reference to the drawings. This embodiment refers to menstrual sanitary napkins. As shown in Fig. 1, Fig. 2, and Fig. 4(a), the absorbent article 1 of the present embodiment includes an absorbent main body 1a, and the side portions 5 are formed to extend to the outside of both sides of the absorbent main body 1a. The above-mentioned absorbent body a includes a liquid-retaining absorbent body 4' covering the surface of the absorbent body*, and having a liquid-permeable abutting skin layer 2 for one of the surfaces of the surface, and covering the bottom surface of the absorbent body 4 and having A liquid impervious bottom layer (abutting a thin layer of underpants) 3. The side flap portion 5 is fixed to the skin contact pad 7 by the surface side joint portion (contact skin side joint portion) 6, and is increased by Z and joined by the bottom side side (abutting the panty side joint portion) 7 9470丨.d〇c is fixed to the bottom layer 3 . The width W of the front side joint portion 6 is formed to be smaller than the width W2 of the bottom side joint portion 7, and the outermost end position of the width WI of the front side joint portion 6 and the outermost end of the width W2 of the bottom side joint portion 7 are the outermost ends. Compared with the position, it is more arranged on the outside. The related absorbent article 1 will be described in detail. The bottom surface layer 3 is formed into a substantially rectangular shape using a material having liquid impermeability, and the absorber 4 is formed into a laminate body using a pulp fiber and an absorbent polymer so as to have liquid retainability. . The contact between the skin thin layer 2 and the bottom layer 3 is a pair, and the absorbent body 4 is interposed therebetween, and the operability of the side flaps 5, wrinkles, offset prevention, and skin feel are ensured. It is also possible to include only the surface thin layer 2& however, it is preferable to include the surface thin layer 2a and the water repellent thin layer 2b from the viewpoint of excluding the risk that the body fluid expansion of the surface thin layer 2a leaks to the side flap portion 5. The absorbent body 4 can absorb the liquid by abutting against the thin layer 2 of the skin, so that the absorbent article 1 becomes a part capable of absorbing liquid from one of its surfaces to the absorbent body 4. More specifically, the absorbent article 1 can absorb liquid from a portion which is present in the central portion in the width direction of the absorbent body 1a and which is not covered by the water repellent thin layer 2b. The surface layer 2a is a material having a liquid permeability, and is subjected to a hydrophilization treatment in a substantially strip shape formed to be smaller than the width of the bottom layer 3. The water repellent thin layer 2b is formed into a two-piece shape so as to be buried on both sides of the surface thin layer 2a with respect to the bottom surface thin layer 3 by using a water-repellent non-woven fabric. The side flap portion 5 is formed by using a material having a property of exhibiting good softness and good adhesion to the bottom surface and having a property for fixing workability on the bottom surface thereof, and an adhesive material (not shown). In particular, as a surface, a material which is a non-woven fabric or a composite material, a high wrinkle/offset prevention material. For materials which are soft and workable, it is preferred that the materials of the selected film conform to the adaptability of the respective materials, and in particular, the viewpoint that the underpants can be well bonded and combined, it is preferred to use an elastomeric property: A flank material having an elastomeric property, preferably a stretchable thin 222, for example, a latent crimping fiber "Women-propylene random (10)) is used as a core component, and a polypropylene (pp) is used as a preform: : shrinking core-type composite fiber as a raw material to produce a sheet-like mesh-like inclusion and =_ material is heated by heating the M-printed material and heat-shrinking the fiber, but may also comprise a film having elastomeric properties Or a composite of mesh and other elastic materials. Further, the method of fixing to the undergarment is not limited to the following materials, and other methods such as fixing by mechanical fasteners may be selected. Next, the position in the absorbent article I is described. The positional relationship of τ and the joined state are described on the upper surface portions of the surface thin layer 2a, and it is difficult to combine the water repellency and thin sound 2b = one side portion. In the joint portion between the surface thin layer 2a and the water repellent thin layer 213, an imprint process by heat sealing is applied. The 钿邛 2b of the surface thin layer side of the refractory Zb is formed so as to protrude from the surface thin layer 2a. ^ 1 as ' and can be used as a body which can block and ooze out from the surface thin layer 2a. * and the leakage preventing wall of the sputum is used as 9470l.doc such that the surface thin layer 2a and the water repellent thin layer 2b are integrated. The surface thin layer 2a covers the surface of the absorbent body 4 (abutting the skin side), and The water repellent layer 2b covers the side of the absorber 4. A surface side joint portion 6 is formed by imprinting between the upper surface portion of the inner side portion of the side flap portion 5 and the other side portion of the water repellent thin layer (outside of the side flap extending direction). In the formation of the surface thin layer "bonding with the water repellent thin layer and the surface side bonding 46, a bonding method for maintaining the softness (skin feel) of the surface side can be selected. It is considered that the penetration of the body fluid into the side flap portion 5 is prevented. It is to be noted that the surface side joint portion 6 is continuously formed in the longitudinal direction (X direction) of the absorbent article 于 in the joint region of the water repellent thin layer 2b and the side flap portion 5. In this case, the side flap portion 5 becomes not directly Bonded to the surface layer, and the body liquid which is impregnated with the surface layer 2a or the body liquid layer which is retained on the surface layer h is interrupted. The side portions 5 are joined to the both sides of the bottom layer 3, respectively. A bottom surface side joint portion 7' is formed between the lower surface of the inner side portion of the side flap portion 5 and the side portion of the bottom surface layer 3, and a hot melt adhesive is used in the present embodiment. In the formation of the bottom surface side joint portion 7, A joining method for ensuring the joint strength (difficult to peel off) of the side flap portion 5 and the bottom sheet thin layer can be selected. From the viewpoint of preventing leakage of body fluid as in the case of the surface side joint portion 6, the bottom side joint portion 7 is at the side flap portion. 5 with a thin layer on the bottom 3 The length of the article 1 is continuously formed in the longitudinal direction.

Further, the upper limit of the width of the bottom side joint portion 7 is not limited to ensure the joint strength between the side flap portion 5 and the bottom surface 4, and the bottom side joint portion 7 may extend over the joint region between the side flap portion 5 and the bottom sheet 3 The entire range may also protrude from the side flaps 5 and be interposed between the absorbent body 4 and the bottom layer 3 . Furthermore, as shown in FIG. 4(c), the bottom side joint portion 7 is considered in view of the fact that it is not necessary to continuously roll in the width direction (y direction) particularly in the state in which the side flap portions 5 are well bonded to the undergarment. It is also possible to vacate the pattern joint of the joint spacers. At this time, the width Wz of the bottom side joint portion 7 is preferably set to 3 to 1 〇. The joint gap is preferably set to 1 to 5 mm. Further, as shown in FIG. 4(c), regarding the surface-side joint portion 6, it is also considered that it is not necessary to be wide and the direction (y-direction) is continuous, in particular, the side flap portion $ is good in workability and is well fitted to the undergarment. In view of the fact that it is easy to curl, and the viewpoint of improving the touch of the skin, it is also possible to vacate the pattern joint of the joint. According to the same viewpoint as described above, the outermost end position of the width of the front side joint portion 6 coincides with the outermost end position of the bottom side joint portion 7, and the outer side surface joint portion 6 which is preferably located outside is joined to the bottom surface side. The width of the surface-side joint portion 6 is preferably set to be 3 to 10 mm. As shown in FIG. 2 and FIG. 4( a ), the absorbent article 1 abuts the side of the thin layer 2 of the skin layer as compared with the position of the side edge of the bottom layer (contact (four) thin layer) 3 . Doc -13· The 4510 edge end position (more specifically, the outer edge end position of the water repellent thin layer 2b) is further located outside the width direction of the absorbent article 1. Further, the outermost end position of the front side joint portion 6 and the outermost end position of the bottom side joint portion 7 are located further outward than the position of the side edge of the absorbent body 4 in the width direction of the absorbent article 1. The method for producing the absorbent article 1 is not particularly limited, and an example of a thin layer of the entire surface of the surface layer 2a is prepared in advance, and a water-repellent thin layer of the water-repellent layer 2b is formed to form a bottom surface. In addition to the thin layer of the bottom layer of the thin layer 3 and the plurality of absorbers 4 (not shown above), it is also necessary to form a full-width sheet of the side flaps of the side flaps 5 (see Fig. 3). , from the surface; the entire layer of the layer of cloth and the entire layer of water-repellent thin layer, forming a continuous surface side continuous body in contact with the skin thin layer 2 in the feeding direction, for which the surface side continuous body is fed according to each fixed interval The body 4 is absorbing and the bottom sheet of the entire web is joined to join to join. As shown in Figure 3, the entire fabric of the flanks is applied to the center of its width D. p is cut into a wavy-shaped flank cut, (9) to form a pair of side ^ / continuation UU ' and for both sides of the flank continuum 11 , a "special ^ direction of the 刖 after cutting before cutting, Thereby, a plurality of - opposite side flaps 12, 12 are formed. And: the side flaps 12 are fed in such a manner that the end surface of the entire fabric of the water repellent thin layer "between the ends of the webs", and to satisfy: The above-described conditions of the joint portion 6 and the bottom surface side joint portion 7 are connected to each other by the means of the above-described conditions, and the continuous body is cut according to the fixed length to form a plurality of absorbent articles 1. As described above, according to the present embodiment, when the side flap portion 5 is joined between the water repellent thin layer 2b and the bottom surface thin layer 3, the width of the front side joint portion 6 is set to be smaller than the width W2 of the bottom surface side joint portion 7, Further, the width w of the front side joint portion 6 and the outermost end position are located further outside than the outermost end position of the width W2 of the bottom side joint portion 7, so that the wing portion 5 can be obtained in the root portion of the side flap portion 5. Good operability when bent on the bottom side. Further, according to the present embodiment, when the side flap portion 5 is joined between the water repellent thin layer 沘 and the bottom enamel layer 3, the front side joint portion 6 is not overlapped with the bottom surface side joint portion 7 and is offset outward in the width direction. According to this configuration, in the root portion of the side flap portion $, it is possible to obtain more excellent operability when the side flap portion 5 is folded to the bottom surface side. Further, according to the present embodiment, the contact thin layer 2 is divided into the surface thin layer 2a and the water repellent thin layer 2b, and the side flap portion 5 is joined to the water repellent thin layer and is separated from the surface thin layer 2a. It is prevented that the body fluid impregnated on the surface layer or the body fluid retained on the surface layer 2a is transferred to and attached to the side flap portion 5. In the case of the present embodiment, in particular, in the root portion of the side flap portion 5, both the front side joint portion 6 and the bottom surface side joint portion 7 are attached to the absorbent article! Since it is continuously formed in the longitudinal direction, it is possible to prevent not only the body fluid of the surface layer 2a but also the body fluid of the absorber 4 from leaking to the side flap portion $. Further, according to the present embodiment, even if the side flap portion 5 is a member different from the skin thin layer 2 and the bottom surface layer 3, as described above, the function of the original absorbent article 1 can be maintained. Therefore, the different componentization of the side flaps 5 is related to the situation in which the amount of use of the entire fabric and the amount of scraps are reduced. Specifically, the side flap portion 5 is formed so that the entire fabric 10 of the flanks does not generate scraps, and the skin thin layer 2 and the bottom thin layer 3 can be narrowed to the absorbent article 1 . The entire fabric of the width is formed in such a manner that the scrap is hardly generated. The related aspect is also the same as the case where the skin thin layer 2 is divided into the surface thin layer 2a and the water repellent thin layer 2b. Next, another preferred embodiment of the present invention (hereinafter also referred to as a second embodiment) will be described with reference to Figs. 5 and 6 . In the description of the absorbent articles (menstrual sanitary napkins) of the second embodiment, the same reference numerals will be given to the same points as those of the above-mentioned absorbent articles, and the same reference numerals are attached to the same portions, and the description thereof will be omitted.
