Description

Description of the invention: [Technical field to which the invention belongs] Shi Yu ΛMing relates to a pant-type diaper, a pant-type absorbent article used as a pant-type diaper or a pant-type physiological article, and a manufacturing method thereof. [Prior art] The city asked about various types of pants-type diapers for infants and adults of the age of one month. Because the pants-type diaper system for young children is moved from diapers to ordinary underwear, and the pants-type diaper system for adults is moved from ordinary underwear to diapers, the main teeth of the aforementioned pants-type diaper system should have the same feeling as ordinary underwear as much as possible. In recent years, the material of the pant-type diaper is a person who uses a touch similar to that of ordinary underwear. In recent years, the absorbent body, which is very important in pants-type diapers, has been most preferably a highly flexible one which can provide comfort to the wearer's skin. Furthermore, the appearance (fluidity) of the -Yuewang pants-type diaper is close to that of ordinary underwear. Then, with the improvement of such pants-type diapers, the development of pants-type physiological products has become more diverse. A method of improving the performance of the side flap of a diaper is to arrange elastic members around the waist of the diaper, and to form a waist hem around the waist. When a hem around the waist is formed on a pant-type diaper using a soft absorbent body, wrinkles are generated in the absorbent body by the elastic member described above, resulting in a difference in appearance from a normal underwear style. Now that the absorbent body is softened, the necessity of using an elastic member that causes wrinkles in the absorbent body is reduced. In order to improve the appearance of the portion where the absorbent body is present, it is desirable to prevent the formation of frills around the lower back. For example, Japanese Patent Laid-Open Publication No. 2001-61890, Japanese Patent Laid-Open Publication No. 2001-286504, Japanese Patent Laid-Open Publication No. 200 1-293030, and Japanese Patent Laid-Open Publication No. 2001-286930. Ichikai Kai 2002-178428: When there is a t-shaped pant-type diaper, a western-style member is disposed in the area that becomes the waist periphery, and then the elastic member is cut off at a specific place only in There is no pant-type diaper in which the waistline hem is formed on the absorbent body (absorbent core). In a pant-type diaper in which a hem around the waist is formed only in a part where the absorber body (absorbent core) does not exist, it is necessary to use an elastic member disposed near the waist opening and a majority of the hem around the waist An elastic member prevents leakage from the ventral side of the diaper (hereinafter referred to as "ventral leakage") and leakage from the back side (hereinafter referred to as "men's leakage"). Therefore, when the individual shrinkage stresses of the plurality of elastic members forming the hem around the waist are larger than those of a pant diaper in which a hem around the waist is formed in a part where the absorber body (absorbent core) is present, set to Strong. However, it is difficult to wear when the individual shrinkage stress of the elastic member forming the hem around the waist is set to be strong. During wearing, the traces of the elastic member are added to the body of the wearer to cause local compression, thereby reducing the wearing feeling. In addition, it is difficult to fix the elastic member itself at a desired position, for example, when the pants-type diaper is worn or worn, a part of the elastic member is unfastened, so that the elastic member contracts. When the fixing of the elastic member is released, the elastic shrinkage of the part is weak, which not only easily causes ventral leakage or back leakage, but also easily causes the diaper to fall off or fall off. Since pants-type diapers are often used for wearers with a large number of activities, it is required to have a function that does not fall off even when performing various actions. [Summary of the Invention] 85556. The first problem of the present invention is to provide a pants-type diaper that can provide fluidity and wearability while having sufficient side flap performance without using expensive materials. In addition, the second problem of the present invention is to provide a compressive mark (hereinafter referred to as a "rubber mark") that maintains the prevention of falling off, and allows the elastic member to feel "softness", " "Panty diaper". The third subject of the present invention is to provide a pants-type absorbent article that is easy to make the appearance the same as ordinary underwear and fly, and has excellent anti-adhesion, wearing feeling and side leakage prevention performance, and it is difficult to fall off even if the wearer performs various actions. . The fourth problem of the present invention is to provide an easy-to-appear appearance similar to ordinary underwear &lt; appearance, excellent wearability, wearing feeling, and side leakage prevention performance. Even if the wearer performs various actions, it is easy to obtain pants-type absorptivity that is difficult to fall off A method for manufacturing a pant-type absorbent article of an article. Hereinafter, the present invention will be specifically described. In addition, although reference numerals have been added to the drawings in order to make the present invention easy to manage the midday afternoon, this does not limit the illustrated form of the present invention. In the first aspect of this ignorance, a pants-type diaper (hereinafter referred to as pants-diaper I) is provided to solve the above-mentioned problem H. The pants-type diaper (1, 100, 200) has the following components : A liquid-permeable surface material (2 丨), a liquid-impermeable leak-proof material (22), and an absorber (23) between the surface material and the leak-proof material, characterized in that it is located in the wearer The upper part of the waist around the waist & the long side of the absorbent body has at least two plates and a side flap area (4iA, 41B, 42A, 42B) without the absorbent body, as described above. Related to the waist, a plurality of elastic members (32) are arranged at an average interval of 5 mm or less between the two plates 85556 1224963 (24A, 24B) at least on the side flap area. The rigidity is 350 mN / 50 mm or less, and the load of 80% of the whole waist circumference is extended to 2 to 8 N. When the number of elastic members provided in the side flap area is set to A, the waist area When the total elongation load is set to bn, B / AS is 0.4N. Here, the "flexural rigidity of the absorber" is the "3-point load-flexible creep of a foot" prescribed in JIS rule 7116. The detailed measurement method of the "flexural rigidity of the absorber" is described later. In the pants g diaper I, since the load for stretching the entire waistline portion (in other words, the stress value when the entire waistline portion is stretched by 80%) is 2 to 8N, it is difficult to cause deviation when worn. In addition, since the number A of the elastic members constituting the waist circumference divided by the load B is equal to B / eight: 0.4 N &amp;: This can suppress the pressure directly below the widthwise section of the elastic member (in the width direction). When the pant-type diaper is worn, the elastic pressure provided to the wearer's waist around the waist by the elastic member mentioned above). That is, since the elongation load mosquito of each elastic member in a state of being assembled to a diaper is below a specific value, it is possible to provide a good wearing feeling for a wearer. Here, the "elongation load" refers to a load (hereinafter, the same) that is required to stretch the elastic member for a fixed length. In addition, the rigidity of the absorbent body is set to be not more than 35mN / 5mm, and since the elongation load per elastic member is small, the absorbent body does not cause large wrinkles, and the discomfort of the wearer disappears. , And can improve comfort. In addition, it can also cause the tooth writer to make a big crying action, which can also prevent the absorbent body from generating large wrinkles. 7Because of the structure as above, for example, even when the elastic member is arranged around 85556 1224963 not only in the side leakage area, it has the advantages described below. That is, the gentleness felt by the spear author is continuous between the part having the absorbent body and the side part of the absorbent body, which can reduce the discomfort when wearing a diaper. Wrinkles, make the side of the absorbent body close to Nakamoto Ashi 2}, and 1 non-Kyang universal when wearing, and a pocket structure is formed on the side, so it can prevent the pollution of excrement. Furthermore, since it is difficult to form a hem (sensitive skirt) on the absorbent body, the width of the absorbent body can be ensured, and there is an advantage that it can be completely received even if a large amount of urine is discharged. In the pants-type diaper I, the two sheets are made of a non-woven fabric which is more isolated from the wearer than the leak-proof material, and the basis weight of the non-woven fabric is 10 to 30 g / m2, which is the fineness of the fibers constituting the non-woven fabric. The degree of elasticity is ⑴i, and the volume softness of at least one side is equal to or lower than the width direction of the product. The upper elastic member and the two plates are fixed by a water-repellent adhesive provided on at least one side of the plate.噙 Here, the density of the water-repellent adhesive set on one side of the non-woven cloth that is provided by wearing a non-woven cloth that touches the SX 'by using a non-woven cloth with specific physical properties is locally increased due to the formation of frills on the elastic member. Therefore, contamination of feces can be prevented. In addition, "bulk softness" is a specific test method of "bulk softness" which is a test evaluation item for evaluating the softness of a nonwoven fabric or the like as described later. The waist of the pant-type diaper is divided at an average interval of 3 mm or less: a plurality of elastic members are formed at the edges in the circumferential direction, and the load at which 80% of the waist opening is fully dazzled is extended to 3 to 6 N. When the number of the aforementioned elastic members at the waist is c, and the load for elongating the entire waist opening by 80% is set to d [n], 85556 -10- 1224963 makes the relation of D / C ^ O.8 N While posing. In the configuration, since the positive and spoon pressures of the elastic members on the waist of the diaper I are dispersed (when wearing the diaper j, the waist weight pressure is exerted on the wearer by the elastic members), the wearer's wear can be reduced. The discomfort when removing the diaper is the same as that of the wearer's waist, and it can also solve the problem of rubber marks on the wearer's waist. In a second aspect of the present invention, a pants-type diaper (hereinafter referred to as a pants-type diaper π) is provided to solve the above-mentioned second problem. The pants-type diaper has the following members: a liquid-permeable surface material ( 21), liquid-impermeable leak-proof material (22), liquid-retaining absorbent (23) interposed between two members, and located on both sides of the waist periphery (9) around the waist of the wearer A plurality of waist elastic members (32) arranged in the circumferential direction are provided on the part, wherein the stress when the waist elastic members are respectively extended twice is 20 gf (i96 cN) or less, and when the extension is tripled. The stress is equal to or less than twice when the elongation is doubled. The interval between the plurality of elastic members around the waist is kept at an average of 5 mm or less, and is arranged between two plates (24 A, 24B). According to this pants-type diaper II, since the stress when the elastic member around each waist doubles is 20 gf (19.6 cN) or less, it is possible to prevent rubber marks on the wearer's skin during wearing. Users (wearers (babies, infants, etc.) of trousers and protectors who help wearers to wear diapers, etc.) can feel "softness" or "softness". In addition, the "double stretch" of the elastic members around the waist corresponds to the stretch rate of a standard-sized (physical) infant when wearing a diaper. In addition, since the stress around the elastic member around the waist is three times lower than the stress when it is doubled, the protector and the like will not have a great resistance when the infant or the like wears a pants-type diaper 85556 1224963 π. . In addition, since the intervals of the plurality of elastic members around the waist are arranged while keeping the average of 5 mm or less, the number of elastic members around the waist can be ensured to be arranged around the waist. Moreover, since the plurality of elastic members are fixed between the two plates, it is possible to prevent the so-called "r" of the elastic member from falling off, and it can be reliably fixed. In this way, according to the pants-type diaper II, problems such as falling-off and rubber marks can be prevented beforehand, and the user can actually feel "softness" or "softness". In a third aspect of the present invention, a pants-type absorbent article is provided to solve the above-mentioned third problem. The pants-type absorbent article (400) has the following components: a liquid-permeable surface material (2 丨) The absorbent body (20) of the liquid-retaining absorbent body (23) is interposed between the liquid-impermeable leak-proof material, the outer layer body (24) to which the absorbent body is fastened, and the absorption described above. The left and right outer sides of the body body are provided with a plurality of waist-peripheral elastic members (32). The outer layer system includes a plurality of sheets laminated with an adhesive, and the waist-peripheral elastic members are fixed to two members constituting the outer layer of bone beans. Between the sheet plates (24a, 24B), the elastic members around the waist are arranged at intervals of 5 mm in the downward direction, and the load required when the elastic members around the waist are doubled is 19.6 cN / If the weight is less than double, the load required for double stretching is less than twice the load required for double stretching. When worn, it is placed around the waist of the wearer's waist (P). The load required for stretching is 80%. 2 N to 8 N, one of the adhesives between the two plates Contact region lies in the region around the absorbent body than the solid body, the adhesive between the two base plate under the weight of a region to Alex! 〇 g / m2. 85556 -12- 1224963 The aforementioned waist-peripheral elastic member is an elastic member for forming a hem around the waist, and the increase rate of the shrinkage stress corresponding to the increase of the respective elongation of the waist-elastic member is small. As described above, in the pants-type absorbent article in which such a waist-peripheral elastic member is disposed, the absorbent body is not substantially formed with ruffles (wrinkles) due to the shrinkage force of the waist-peripheral elastic member, so that Its appearance is the same as ordinary underwear (the appearance is the same. Also, it is easy to widen the waist opening when wearing: it has high spear resistance. When focusing on the distribution of the shrinkage stress of the elastic members around the waist around the waist, This distribution is also difficult to deviate during wearing, so it is difficult to cause the traces of the lumbosacral member to be locally pressed on the body of the wearer, which makes the wearing feeling excellent. Also, preventing the whole around the waist from falling off can obtain sufficient Shrinkage stress, and since the elastic members around each waist are easily fixed at the desired position even during wearing, it is easy to prevent ventral leakage or back leakage, and it is easy to prevent the pants-type absorbent article from falling off easily or Easy to take off. Tian Zai, the application of the adhesive that forms the outer layer is selected as described above, because it can be confirmed even when wearing a pants-type absorbent article. Each elastic member around the waist is fixed at a desired position, and a reduction in touch or softness around the waist can be suppressed. Therefore, it is also an excellent pants-type absorbent article from this point of view. In a fourth aspect of the invention, a method for manufacturing a pants-type absorbent article is provided to solve the above-mentioned fourth problem. The method for manufacturing the pants-type absorbent article (400) has the following components. Permeable surface material ⑵) and liquid-impermeable 85556 -13- An absorbent body (20) with a liquid-retaining absorbent body (23) interposed between the liquid-impermeable leak-proof material (22), and the absorbent body The fixed outer layer body (24) and a plurality of waist elastic members (32) arranged on the left and right outer sides of the absorber body, the outer layer system includes a plurality of sheets laminated with an adhesive (54), The waist elastic member is fixed between the two plates (4A and 24B) constituting the outer layer body. The special feature is that it has the following steps: transporting the first plate material in a manner that the long side direction of the first plate material moves to the moving direction and becomes I-plate of square shape with two plates (50), and when it becomes a pants-type absorbent article on the i-th panel material, apply the adhesive on the area around the waist around the waist of the wearer; The second step of applying the adhesive intermittently in the longitudinal direction on the long-length elastic body (56) of the elastic member around the waist is after applying the oil; The long-length elastic body is held and fixed on the first plate material: between the second plate material that becomes the other of the two plate materials, the third plate is known, and in the second step, it is not in the long plate shape. The fourth step of cutting the area by pressing a plurality of protruding members from the outside of the first plate material or the second plate material on the area where the adhesive is applied; and on the first plate The fifth step of fixing the absorbent body to the material or the second plate material. Since U is applied to a long-length elastic body that becomes an elastic member around the waist, even if a low-density elastic body is used as the long-length elastic body, it is possible to suppress undesired breakage during the manufacturing process of the pants absorbent article. Therefore, the pants-type absorbent article according to the third aspect can be easily manufactured. [Embodiment] 85556 -14- In the following, the embodiment of the cloth and the manufacturing method of the pants-type absorbent physical article will be specifically described in order with reference to the drawings. <Pants-type diaper I. First embodiment. 1 &gt; Fig. 1 is a perspective view of a pants shape according to a first aspect of the present invention. The shape of the trousers and mouth of the present invention and the trousers' absorption are explained. The elastic diaper 1 (for babies), one of the embodiments, is provided in the side flap area. The diaper I shown in the figure has : 配 &; — 〃 is also on the ventral portion 2 on the ventral side of the wearer, the dorsal portion 3 on the back side, and the lower portion 4 between the members. The side portions of the ventral portion 2 and the sides of the dorsal center are connected to each other, and a waist opening portion 5 and a pair of leg opening portions 6A and 6B are formed. The waist portion 7 located at the waist opening Shao 5 is formed with a waist ruffle 8 all over the width direction (body width direction) of the diaper. The waist portion 7 includes an area on one end of the waist opening portion 5. When viewed from the long-side direction (crotch direction) of the pant diaper 1, the I degree of the waist loop 7 corresponds to the end of the waist opening portion 5 and One-third of the distance between the leg openings 68 and the ends of the fairy side (meaning the ends of the waist openings 5A of the leg openings 6A and 6B). The waist periphery 9 is located below the waist 7 and the waist periphery 9 is formed with a waist periphery ruffle 10. The waistline portion 9 is an area connected to the waistline portion 7. When viewed from the long-side direction (crotch direction) of the pant diaper 1, the width of the waistline portion 9 is equivalent to two thirds of the distance. The waist hem 10 is not disposed on the entire periphery of the perimeter part 9 but is disposed only on its side. A pair of leg openings 6A and 6B are formed with leg hem 11A and 11B on the entire circumference of the opening, respectively, adjacent to the leg hem 11A and 11B, 85556 -15-1224963, and are provided as Three-dimensionally guided three-dimensional frills 26A and 2.6B (only three-dimensional frills 26A are shown in FIG. 1).

Fig. 2 is a plan view of an extended state of the state before constituting the pant-type diaper 1 shown in Fig. 1 as viewed from the side in contact with the wearer's skin. 3 is a sectional view taken along the line III-III in FIG. 2. In addition, in FIG. 2, the drawings of the three-dimensional frills 26 A and 2 6 B are omitted for convenience. In Figs. 2 and 3, the pants-type diaper 1 basically includes a vertically long absorbent body 20 and an outer layer body 24 disposed on the leak-proof material 22 side of the absorbent body 20. The absorbent body 20 includes a liquid-permeable surface material 21, a liquid-impermeable back material 22, and a liquid-retaining absorbent body 23 interposed between the two members 21 and 22. The absorbent body 23 absorbs The base paper 25 is covered. The outer layer body 24 is two sheets of material, that is, the non-woven fabric 24A covering the legs including the leak-proof material 22 side, and the outermost surface of the pant diaper 1 is disposed so as to face the non-woven fabric 24A covering the legs. Non-woven outer layer 2 * b. The surface material 21 and the leakage preventing material 2 2 may be formed in any of rectangular shapes. The absorbent body 2 3 may be formed in a rectangular shape or an hourglass shape in which the central portion of the two long sides of the rectangular shape is recessed inward. The surface material 21, the leakage preventing material 22, and the absorbent body 23 are joined to each other by a specific means, and the rectangular absorbent body 20 is formed as a whole. The longitudinal direction of the absorber main body 20 coincides with the longitudinal direction of the outer layer body 24 and is arranged at a substantially central portion of the outer layer body 24. The outer layer body 24 forms the outer shape of the pants-type diaper 1. The outer nonwoven fabric 24B constituting the outer layer body 24 forms the outermost surface of the pants-type diaper 1. The nonwoven fabric 24A covering the legs is joined to the inner surface side of the outer layer nonwoven fabric 24B. The outer edges of both sides of the outer layer body 24 are formed at the central portion in the longitudinal direction 85556 -16-1224963 to form an hourglass shape recessed to the inside. Three leg elastic members 30A, 3 are respectively arranged between the left and right leg openings 6a, 6B between the non-woven fabric 24a covering the legs and the outer nonwoven fabric 24B constituting the outer layer body 24 in the extended state. 〇B. Thereby, when the pant-type diaper 1 is formed, completely continuous leg hem 11A, 11B is formed around the periphery of the leg openings 6A, 6B. Three-dimensional hems 26a and 26B are formed on the left and right sides of the absorber body 20. Each of the private edges 26 A and 26B has fixed ends 27A and 27B fixed to the surface material 21 and unfixed free ends 28A and 28B along the longitudinal direction of the absorber body 20. Near the free ends 28A and 28B, elastic members 29A and 29B for three-dimensional frills are arranged in an extended state. With this, at least when wearing pant urine, the three-dimensional white edges 26A, 26B are raised in the direction of the wearer's skin in such a way that the '28A, 28B can be freely seen from the plane, and the liquid is prevented from being directed toward the absorber body. Side width leak. Fig. 4 (a) is a sectional view taken along the line IV-IV in Fig. 2. Hereinafter, referring to the drawings, FIG. 2 and FIG. 4 (a), the waist ruffle 8 and the waist-surrounding ruffle 10 will be described. The front and rear ends of the outer layer body 24 are along the front and rear edges 5A and 5B (the edges of the waist opening Shao 5 forming the shape of the diaper 1). . The waist elastic member 31 is held in a stretched state by a non-woven fabric 24A covering the legs and an outer non-woven fabric 24B. When the side edges 2A, 3B of the ventral portion 2 of the pants-type diaper 1 and the two inverted edges 3A, 3B of the back portion 3 are joined to each other, one end of the waist elastic member 31 is disposed so as to overlap the other end . As a result, the waist elastic members 31 are aligned neatly in the circumferential direction of the waist opening 5 of the pant diaper 1. As shown in Figure 丨, the waist opening = 85556 -17-1224963 Side 8. As described above, the waist periphery 9 is divided into three regions by the distance between the three-division waist opening 5 and the leg openings 6A and 6B in the longitudinal direction of the diaper, leaving a region closest to the waist opening 5 Remove the remaining two areas. In this embodiment, a waist elastic member 32 is provided in at least one of the three regions. The waist elastic member 32 is arranged on the ventral portion 2 and the back portion 3 of the pants-type diaper 1 in areas 41 a, 41B, 42A, and 42B (leak-proof side areas) which are more outward than the side edges of the absorbent body 23. ). The elastic members 32 around the waist are held and fixed in a stretched state by the nonwoven fabric 24A covering the legs and the outer nonwoven fabric 24B so that the elasticity can be found. When each of the waist-side elastic members 32 joins the side edges 2A and 2B of the ventral portion 2 of the pant-type diaper 1 and the side edges 3A and 3B of the back-side portion 3 with each other, The special waist elastic members 32 are substantially overlapped, and the two waist elastic members 32 are arranged substantially so as to obtain one continuous elastic member. According to this method, the waist elastic members 32 are aligned in the circumferential direction of the waist 9 of the naked diaper 1 as shown in FIG. 丨, and are more outward than the side edges of the absorbent body 23 of the pants diaper. The area 41, 8, 41B, 42A, 42B is formed with a hem around the waist 10. In the present embodiment, the wearer's waist is comfortable with moderate stress and does not fall off. From the viewpoint of preventing the wearer's perimeter from being fastened, the waist circumference 9 is extended as a whole. 80% of the load is set to 2 to 8N, more preferably 3 to 7N, and most preferably 4 to 6N. In addition, when the load for extending the entire waistline portion 9 by 80 ° / 设为 is set to "b" N and the number of elastic members constituting the waistline portion 85556 -18-1224963 9 is set to "A", The value "b / a" is preferably 0.4 N or less, more preferably 0.3 N or less, and most preferably 0.25 N or less. As mentioned above, by adding $ 1 to the female, the waist elastic member constituting the waist periphery 9 is extended by 8G% of the load "B / Α", which can reduce the elastic member in the width direction directly under the cut (the wearer's Skin side) pressure (line pressure). This makes it possible to prevent rubber traces from being formed around the wearer's waist when wearing the trousers | cloth i. Furthermore, it can provide a comfortable use feeling for the wearer. In addition, the upper sling "80% of the load" cuts only the waist circumference of the pant-type diaper in a ring shape, and the length when the waist circumference is maximized in the diameter direction is set to 100% It can be stretched to 80% load. This load was measured by an electronic theoretical universal testing machine. The flexural rigidity of the absorber 23 in this embodiment is set to be 35 mN / 50 mm or less, more preferably 300 mN / 50 mm or less, and particularly ⑽ mN / 50 mm or less. With this setting, a soft absorbent body 23 can be realized. The discomfort of the wearer is eliminated by the soft absorbent body 23. It can also make the diaper &quot; tile linear. Furthermore, even if the wearer performs a sudden movement, the absorbent body 23 does not cause large wrinkles. When forming such a soft absorbent body 23, the basis weight of the defibrated pulp used in the absorbent body 23 or the pressing conditions during molding must be appropriately determined under the condition that the thickness of the entire diaper must reach the thickness of the special thickness. In addition, when the absorbent body 23 is mixed with a water-absorptive polymer, the polymer is mixed with the restriction condition that the absorbent body must be made softer. Therefore, a small amount of the polymer is used, that is, a small amount of water-absorbing polymer is used. High-performance polymers are the most ideal for 85556 -19-1224963. In addition, the measurement of the rigidity of the absorber was performed using an electronic theoretical universal testing machine [RTC-1150A manufactured by ORIENTEC Co., Ltd.] in accordance with the JIS standard K7116 method (test method for flexural characteristics of plastics) (Rl = 50 ° 0.1 mm, R2 = 5 · 〇 ± 0 · 2 mm fixed). The test piece was placed so that the distance L between the side piers was set to 50 mm between the support stands, and the tip end portion of the press was placed so as to contact only the test piece. &quot;, J force agent 5 kg (limit 1.96 N), the pressure is lowered at a speed of 30 mm / min to obtain a load bending curve. The maximum value of the obtained bending load was set as the bending rigidity value (mN / 50 mm). 4 The test sheet is cut from the surface of the diaper with no frills and small / central creases, wrinkles, etc., with a length of 50 mm in the longitudinal direction and 80 mm in the width direction of the diaper. It is a structural member from a material to a leak-proof material. The unit "50 mm" including the flexural rigidity is the length of the short side of the test piece, and the width of the test piece that was bent by the indenter during the test. 85556 In the pant-type diaper of this embodiment, from the viewpoint of preventing the effect of preventing the contamination of fecal matter with the soft feel of the diaper, the elastic members 32 around the waist are made of silk rubber, and the thickness ( Fineness) is preferably not more than 39〇1, and more preferably not more than 310dtex. If the thickness of the elastic members 32 around each waist exceeds the thickness described above, it is actually difficult for the wearer and the protector who wears the diaper to feel that "softness" or "gentleness" is easily on the skin of the author Leaves rubber marks. In addition, the elasticity around the waist: the member 32 is fixed to the non-woven cloth covering the legs—and the outer layer of non-woven cloth 'to directly apply an adhesive to the elastic member 32 around the waist. Under this condition of -20-1224963, even if the silk rubber which is generally easy to detach becomes a state of any kind of expansion and contraction, it is difficult to detach, and the above-mentioned effect can be surely achieved. Moreover, each waist elastic member 32 is optimally arrange | positioned so that each space | interval may become 5 mm or less on average. Thereby, in order to prevent the pant-type diaper 1 from falling off from the wearer, it is ensured that the required number of waist elastic members 32 are arranged on the waist periphery portion 9. In addition, by arranging the elastic members 32 of silk rubber set at the above-mentioned thickness at an average interval of 5 mm or less, even pants-type diapers can be widely changed (for example, a wearer weighing 12 kg to 22 kg has a symmetrical size) (Range) Hours' can also be used. Ί 疋 Provides gentle and soft touch for tooth writers. With this configuration, the waist elastic member 32 is provided on the side of the absorbent body 20 of the waist periphery 9 and only a specific portion is fastened to obtain a sense of physical and mental relaxation, and the effect of preventing side leakage can be unexpectedly improved. The structure is presumed as follows. That is, excreted urine or soft stools easily diffuse to the absorbent body, and in particular, there is a high tendency to move to the waist region 9 in the sleeping state. At this time, urine or soft stools are stagnated on the absorbent body 23 of the waist region 9, and then slowly absorbed by the absorbent body to be absorbed. However, when the rigidity of the absorbent body 23 is low, the ruffles on the side portions are large, and urine or softness moves from here to the outside of the absorbent body 23. However, in this application form, the elongation load of the elastic members around the waist has the above-mentioned general characteristics. Since the arrangement distance is reduced to form a fine ruffle (the waist around the hem 10), it is presumed to prevent it. Urine and the like move to the side. In the complaint of "Bebeshikai", since a thinner elastic body is used as the elastic member 32 around the waist, the adhesion strength with the plate member on the other side of the elastic member is not good. Because of &amp; it is ideal to apply the adhesive directly to the elastic member. At this time, the formation density of the adhesive is compared with the formation of the fine hem (the waist hem 10) and the formation of 85556 * 21-1224963 thick hem. The &amp; ability to transmit to the upper surface of the absorbent body 20 (liquid permeable top plate (surface material), etc.) has a high ability to block contaminated excreta. In addition, as shown in this embodiment, when one pair of private edges 26, 26B is provided on the outer sides of the absorbent body, in combination with the above-mentioned fine ruffles (round waist ruffles 10), side leakage can be prevented This is because of the following structure. That is, the three-dimensional frills 26A, 26B generally form a three-dimensional space (pocket) that physically prevents the liquid from leaking to the side edges of the absorbent body. When the elongation load of the member is strong, the three-dimensional white edges 26A and 26B are also contracted by the contraction of the side edges of the absorber, which may cause the capacity of the pocket to decrease. In contrast, as in this embodiment, one by one The elongation load of the elastic member around the waist has the above-mentioned characteristics, and by reducing the arrangement distance, the shrinkage of the side edge portion of the absorbent body 23 is reduced. As a result, the capacity of the pocket for preventing side leakage can be maintained as designed, and the side can be improved. The performance of the flap. Non-woven 24A and outer non-woven 24B that cover the legs while holding and fixing the elastic member 3 of the waist in an extended state. From the viewpoint of giving a gentle touch to the wearer, 'I hope the basis weight 10 § / 1112 to 30 g / m2, more preferably J 5 g / m2 to 25 g / m2, especially 15 § / 1112 to 20 g / m2. Also, a non-woven fabric 24A covering the legs In either of the outer nonwoven fabric 24B, it is best to use a water-repellent adhesive when fixing the elastic member 31. In this way, the water-repellent adhesive is locally increased in density by the hem of the elastic member. Pollution. Since the waist elastic member 32 is fixed between the non-woven fabric 24A covering the legs and the outer nonwoven fabric 24B, it is possible to prevent the so-called 85556 -22-1224963 from the waist elastic member 32 to be securely fixed. In addition, since the two plates for holding and holding the elastic member 32 around the waist are made of non-woven fabric, it does not hinder the stretchability of the waist periphery and can provide the wearer with a soft touch. Bei Shiyuan's complaint 'for the purpose of effectively obtaining the above-mentioned effects, use silk rubber as the elastic members 32 around each waist, and use silk rubber thinner than conventional (specifically, the fineness is 39 dtex or less, And thought that the best below 30mtex). However, such a thin elastic member is introduced into a diaper board during the manufacturing process, and the member is placed in an environment that is in contact with the lead-in bearing and has a large frictional force and is easily broken. Therefore, in order to reduce the frictional force of the thin elastic member, an oil is applied to its surface. This is because it can prevent adhesion to the diaper plate member: it makes it difficult to fix, for example, even if it can be temporarily fixed, it cannot withstand the large expansion and contraction width of the diaper, which requires a large size and suitability. Peel off. However, the inventors and others who have filed in this application have broken the knowledge based on the physical properties of the elastic member, the type of the plate member, the type of the adhesive, and the method of manufacturing the surface. f Combination: the method of lowering the material surface to the material surface and the method of making the surface of (5) can overturn the common sense. Use the person who decreases the increase rate of the load relative to the increase of the elongation (the load of the elongation is 2 times that of the elongation). 2 times the load) as an elastic member. ⑺Use basis weight 1. Those up to 30 g / m2 are used as the holding sheet. ] 85556 -23- 3 1224963 (3) The average thickness (average fineness) of the fibers used in at least one of the two sheets is below 4 · 5 dtex (preferably below 20 dtex). (4) Styrene-butadiene-styrene hetero-molecular copolymer (Styrene-butadiene styrene bloc copioid), and styrene-ethyl, Greek, and pentamidine-co-polymer ( styrene isoprene styrene block Copolymerization) as a binder. (5) Apply an adhesive of 10 to 50 g / m2 (20 to 40 is the most desirable) on the elastic member, and fix and fix the two sheets. It is ideal to fix the two non-woven fabrics (board materials) of the elastic member 32 around the foot. At this time, the adhesive may be applied to at least one of the nonwoven fabric 24A covering the legs and the outer nonwoven fabric 24B. In addition, by applying an adhesive to the non-woven fabric, the fixing of the elastic member 32 around the waist can be made stronger and stronger, and the elastic member will not fall off even if the wearer performs irregular and intense movements. In addition, at this time, the amount of adhesive applied to the non-woven fabric is reduced (the specific application amount is 1 to 8 g / m2), and the frills generated by arranging the thin elastic members at short intervals ( The ruffles around the waist 10) provide a soft feel to the diaper. Fig. 20 is a perspective view of an example of a conventional pant-type diaper. The figure is a cross-sectional view corresponding to the same position as that of FIG. 4 (a) of the conventional pant diaper. Comparison Fig. 1 and Fig. 20, the pants-type diaper of this embodiment! The hem around the waist is smaller than the waist hem 510 of the conventional pant-type diaper 500 and forms a large number. 4 (a) and FIG. 4 (b), the difference between the thickness of the waist elastic members 32 and 532 of the diapers 1 and 500 and the number of used elastic members is more obvious. In addition, since the constituent elements of the conventional pant diaper 500 shown in FIG. 20 and the constituent elements having the same or similar functions are all shown in FIG. 1, 85565 -24-1224963 added to the constituent elements shown in FIG. 1 is referred to (The numerical part is added with the reference sign of 500. The same applies to FIG. 4 (b). An example of the method for manufacturing the pants-type diaper of this embodiment is as follows. When manufacturing the outer layer body 24, firstly apply a full coating on the outer layer body non-woven fabric 24B. Apply a hot-melt adhesive. Then, the waist-peripheral portion 9 is provided with a fixed elastic member 32 around the waist in a specific stretched state along the width direction of the outer nonwoven fabric 24B. Then, the waist-elastic member 32 is provided at a specific position in a specific stretched state. It is assumed that the waist elastic member 31 and the leg elastic members 30A and 30B are fixed. Then, the non-woven fabric 24A covering the legs is overlapped on the outer layer of non-woven fabric and the two are joined together. Then, it is cut in the width direction-central part. The waist elastic member 32. In this way, the outer layer body 24 can be obtained. In addition, the absorber body 20 is manufactured according to a general manufacturing method. Then, the absorber body 20 and the outer layer body 24 are fixed by partial bonding. Furthermore, the left and right side edges 28, 2B, 3A, and 3B of the ventral portion 2 and the dorsal portion 3 of the outer layer body 24 are respectively fixed and fixed as the pants shape, and the pants urine of this embodiment is obtained. A method such as heat sealing, high frequency sealing, and ultrasonic sealing is used. The surface material 21 constituting the diaper 1 of the present embodiment is a liquid-permeable panel that allows excretion to pass through the absorbent body 23, and has a tactile feel close to that of an undershirt. For example, woven fabric, non-woven fabric, porous film, etc. The material of the leak-proof material 22 is the most impervious to the use of polymers such as polyethylene, polypropylene, and polyester. From the viewpoint of preventing stuffiness, The above board is best provided with moisture permeability. &Gt; The absorbent body 2 3 is mainly composed of defibrillated pulp and a water-absorbent polymer, and is a mixture of thermoplastic resin, cellulose fiber, and water-absorbent polymer. The heat treatment is best applied. The shape of the absorbent body 23 is rectangular or hourglass-shaped 85556 -25-1224963, etc. Although its structure is ideal, a single layer or two layers are listed, but it is not limited to this. . Elastic member for three-dimensional skirt 29A, 29B, leg elastic member removal, lion and waist elastic member 31 is an elastomer composed of natural rubber or synthetic rubber, and its shape can be any of silk, filament, film, and ribbon The waist elastic member 32 series can be, for example, "ie" (product name: registered two-standard) manufactured by Todobon Corporation _-PONT TORAY CA, LTD, and "RGiea" (product name: (Registered trademark), "Silver Queen" (referred to as (registered trademark: registered trademark)) manufactured by ASAHItEC Co., Ltd., but the present invention is not limited to this. The non-woven fabric 24A covering the legs and the outer non-woven fabric 24B series include: Transparent thrh) non-woven fabric, thermo-lepton (fine r〇ii) non-woven fabric, spunbond non-woven fabric, spunlace non-woven fabric, meh blown non-woven fabric, laminated solution spraying type Non-woven fabrics with spunbond &lt; non-woven fabrics (such as SM + S (㈣, material, spunbond)), SMMS (spunbond, solvent spray, bright spray, spunbond), etc. However, the present invention is not limited to this. Non-woven fabrics are made of polypropylene, polyethylene, or polyethylene-polypropylene random copolymers (p〇 丨 州 ㈣_Polyp-ylene randomeopolymer) and other resin-based resins. , Dimensional, polyg purpose fiber, polyaramide fiber, etc. are the best. The fiber structure includes single fiber, core / sheath fiber, and side-by-side fiber. Considering the touch (skin feel), price, and strength of the non-woven 2 4 A covering the legs, especially considering the stability and stability of the elastic members around the waist 85056 -26- Temple &quot; Six I? Also, fubu,-, non-woven fabric, SMSf woven fabric, SMMS non-woven fabric are the most ideal. In terms of the thickness (fineness) of you and Dai Yan, from the viewpoint of obtaining good tactile sensation, it is preferably lower than 3.0. From the viewpoint of the touch (skin feel), price, and spring of the Λ outer layer nonwoven fabric 24B, the penetration type nonwoven fabric is best. The thickness of the fiber can be good to the touch, especially from the point of view of fine pleating (Shirring), it is better to be less than 2.0 dtex. The non-woven fabric 24A covering the legs and the outside: The non-woven fabric 24B is best treated by applying a water repellent treatment when the leakproofness of the liquid is considered. When a nonwoven fabric other than a spunbond is used for the nonwoven fabric 24A covering the legs, a spunbond nonwoven fabric may be used for the outer nonwoven fabric 24B. When a spunbond nonwoven fabric is used on either side, the fixing stability of the elastic member 32 around the waist can be further improved. Although the adhesive is most preferably a hot-melt adhesive from the viewpoint of simplification of the manufacturing steps and ensuring the adhesive strength, the present invention is not limited to this. Ethyl acetate, petroleum resin, cold glue can also be used. (C〇id glue) and so on. The inventors of the present application, etc., have introduced the concept of "bulk softness" that should be used to evaluate the softness of the non-woven fabric used in order to construct a pant-type diaper with a good feel. A method for evaluating the softness of the volume will be described below. [Preparation of test piece] The two plates holding the elastomer were taken out from the product, and they were separated using an organic solvent. After being completely dried, a rectangle of 30 mm in length and 150 mm in length was cut out of the product (see FIG. 5 (a)). Each test piece was made into a cylinder having a diameter of 45 mm and a height of 30 mm (overlapping width of about 8 mm), ultrasonically sealed 85556 -27-1224963, and the upper end and the lower end were bonded together, and a measurement sample was performed (see FIG. 5 (b)). [Measuring method] Using a compression tester, the maximum load shown when the circumference of the upper end of the measurement sample was compressed to a cylindrical direction (height direction) at a compression speed of 10 mm / min was measured as the volume softness. The above-mentioned volume softness in the width direction of the product (pants-type diaper) is preferably N / 30 mm or less on at least one of the non-woven fabric 24 A covering the legs and the outer non-woven fabric 24B. The pants-type diaper 1 (hereinafter referred to as "Example 1") and the conventional pants-type diaper (hereinafter referred to as Comparative Example 1) of the first embodiment described above are various in terms of hand touch, wearing pressure, and various The performance was evaluated as follows. (A) Evaluation of hand feel The resistance measurement at the time of contact was used as an index of softness around the waist. [Measuring device] An automated surface testing machine (KESFBA-AUTC ^ a) manufactured by CARTEC Corporation was used. [Measuring method] A non-elongated sample was fixed on an acrylic plate with a double-sided tape, and the sample was placed on a sample table with the surface facing upward for measurement. [Measurement conditions] The measurement speed (moving speed of the sample table) was set to i mm / sec, and the friction measurement weight (W) was 0.5 N. The average surface friction coefficient obtained from the measurement was used to obtain the frictional force ((F), resistance) in the following formula. The measurement was performed at least three times, and the average value of the frictional force was set to softness. 85556 -28- 1224963 F = pW [Measurement results] are shown in Table 1. Table 1 Rigidity of diaper type absorber (mN / 50 mm) P Final softness (mN) type and fineness interval (mm) around the waist BB / A Example 1 250 Silk rubber 310 dtex 4.0 4.0 0.25 180 Comparison Example 1 250 silk rubber 470 dtex 7.5 4.1 0.53 270 It is clear from Table 1 that the softness of the pant diaper 1 (Example 1) of this embodiment is smaller than that of a conventional product (Comparative Example 1), and the value is small. That is, the frictional force is small, indicating that it is softer than conventional products. (B) Wearing pressure directly below the elastomer [Measurement method] Wear a diaper (L size) on a vinyl chloride tube (perimeter 570 mm), and measure the wearing pressure on the side of the waist. A clothing pressure measuring device (AMI 3 037-2) manufactured by AMI Corporation was used, and the value of the number of elastomers applied to the sensor used for the measurement divided by the wearing pressure was used as the wearing pressure directly below the elastomer. The measured value of each point of the side part of the waist periphery shows a frequency (%). The samples are Example 1 and Comparative Example 1 in Table 1. "Measurement result" is shown in Table 2. 85556 -29- Table 2

In addition, there is no rubber mark on the skin wearing 7, 、 # to obtain a soft touch. (C) Various performance evaluations. Various changes were made to the absorbent body, the fineness of the elastic body disposed at the waist and the interval between the elastic bodies, and samples were prepared (Examples 2 to 3, and Comparative Examples 2 to 4). With respect to the above samples, the load B that stretches the entire waist circumference part by 80%, the appearance (flow linearity), the rubber traces of the wearer's waist circumference, drop, and absorbency are also evaluated. The test methods for each evaluation item are as follows 85556 -30- 1224963

8Load 80% of the total waist circumference B "80% of the total waist weight" is cut in the waistline of the pant-type diaper only in a ring shape, and the maximum The length is ⑽%, and the length of the load to jump is measured under the condition of "test speed · mm / min" using an electronic theoretical universal testing machine.

(D) The cross section is enlarged and compared, and the body side part (leak-proof side area) of the pants-type diaper 1 (Example 1) of this embodiment and the conventional pants-type diaper (Comparative example 2) were cut | disconnected horizontally in the upright position. , Take a micrograph of the cut surface and compare the two. Fig. 6 (a) is a pant diaper 1 of the present embodiment, and (b) is a cross-section microphotograph of 1,224,963 sheets of a conventional pant diaper. The scale length of each photo is expressed in 5 mm. Comparing the two, it can be seen that the pants-type diaper according to this embodiment is more thin than the conventional pants. As a result, the concentration process of the pressure part is reduced, and the pressure is dispersed, and no local high pressure is generated on the wearer's skin, and no rubber marks are generated. &lt; Second embodiment of pant-type diaper I: pant-type diaper with fine frills also formed at the waist portion Fig. 7 is a perspective view of a second embodiment of pant-type diaper. The structure of the pant diaper 100 shown in the figure is the same as the structure of the pant diaper described above, except that the waist 7 is made of thin silk rubber as the elastic member for forming the hem. Forms fine waistline frills 108. Among the constituent members or regions shown in Fig. 7, constituent members and regions other than the waist hem 108 are assigned the same reference numerals as those used in Fig. 1, and descriptions thereof are omitted. Specifically, the waist-periphery ruffle 108 is formed by arranging a plurality of elastic members (waist elastic members) for forming a ruffle that extend in the circumferential direction on the waist portion 7 with an average interval of 3 mm or less. In addition, the load of the elongating sail of the entire waist opening 5 is set to 3 to 6 N, and the range of ⑴N is optimal. Furthermore, when the number of elastic members at the waist (waist elastic members) is set to c, and the entire waist opening is extended by 80%, the load is set to * DN,

The relationship of D / C ^ 0.8 N is established and the medium-length load γ of each elastic member at the waist is set in this way. Because the square κ is 7 A, the pressure directly below the elastic member at the waist # 7 ( When wearing pant-type diapers at 100, it is possible to reduce the uncomfortable feeling when wearing and taking off diapers. And: the same as the wearer's waist around-can solve the problem of rubber traces on the wearer's waist. In addition, from the viewpoint of improving the performance of preventing side leakage, the load of elongating the entire waist opening by 80% is greater than that of extending the entire waist peripheral portion 9. The loading method constitutes the best. In this way, by increasing the elongation load of the waist 7 to be larger than the waist circumference. The elongation load of 9 can reduce the pressing pressure of the waist circumference 9 on the wearer, and the pocket structure formed by the absorbent body and the side can be exerted. Better results. The method for manufacturing the pants-type diaper 100 of this embodiment is basically the same as that described for the pants-type diaper i of the third embodiment. The above-mentioned condition may be satisfied when the waist elastic member is arranged and fixed at a specific position of the waist 7 in a specific stretched state. &lt; Third embodiment of pant diaper I: diaper 1 provided with elastic members over the entire circumference &gt; Fig. 8 is a perspective view of a third embodiment of a pant diaper! The basic structure of the butterfly-type diaper 200 is the same as that of the pants-type diaper 100 described above, except that a thin silk rubber is also used as the elastic member for forming the hem at the waist 7 to form a thin waist hem 108. In addition, a thin waist elastic member is arranged on the entire periphery 2 of the waist periphery 9, and a waist periphery tip 208 is formed on the entire periphery of the waist periphery 9. Here, although it is different from the pant diaper 100 in which the waist circumference is provided only at the waist circumference, the other configuration is different. In the constituent members or regions shown in FIG. 8, the waist is ruffled. Constituent members and areas other than 2008 are added with the same reference symbols as those used in FIG. 7 and will be omitted from the description of 85556 -34-1224963. As described above, the following is an example of a method of manufacturing a pant-type diaper 200 in which a waist-peripheral elastic member is provided around the waist 7. When manufacturing the outer layer body, the first step is to coat the outer layer of non-woven fabric with a hot-melt adhesive. Then, the waist-peripheral elastic member is fixed in a state in which the waist-peripheral portion is extended along the width direction of the outer nonwoven fabric. Then, the waist elastic member and the leg elastic member are respectively arranged and fixed at a specific position in a specific extended state. Then, on the outer nonwoven fabric, the leg nonwoven fabric is overlapped and the two are joined. _ This way you get the outer body. In addition, the absorber body is manufactured according to a general manufacturing method. Then, the absorber body and the outer layer body are fixed and bonded by shao points. Then, the left and right side edges of the ventral portion and the backside portion of the outer layer body were respectively joined and fixed to form a pants shape 'to obtain the pants-type diaper 200 of this embodiment. In this way, by providing an elastic member around the waist around the entire periphery of the waist portion 9, the wearer can continuously feel the softness between the portion of the absorbent body and the side portion of the absorbent body. comfortability. In addition, large wrinkles are prevented from being generated in the absorbent body. Since the side portion of the absorbent body is close to the central direction when worn, a pocket structure is formed on the side portion to prevent contamination of excrement. Furthermore, since it is difficult to form frills (knocks) on the absorbent body, the visibility of the absorption m can be ensured. This has the advantage that it can be completely absorbed even if a large amount of urine is discharged. -Although the best embodiment related to the pant diaper j of the present invention has been described above, the pant diaper I of the present invention is not limited to the implementation complaints disclosed in this specification. Appropriate changes can be made within the scope of the spirit or idea of the disclosed invention 85556-35-, and pants-type diapers with such changes are also included in the technical scope of the present invention. According to the pants-type diaper I of the present invention, since the weight B which lengthens the entire periphery of the waist by 80/0 is set to 2 to 8 N, it is difficult to cause deviation when worn. In addition, the value b / a divided by the weight a divided by the number a of the elastic members constituting the waist periphery is less than or equal to 0.4 N ', so that the portion directly under the width direction of the elastic member can be reduced &lt; pressure (Line pressure). That is, since the elongation load of each elastic member is set to a specific value or less, the wearer can provide a good wearing feeling at the same time as the traces around the waist of the wearer can be suppressed. It is also 'softer when the rigidity of the absorbent body is less than 3500 mN / 5 0 mm, and as a result, the absorbent body does not cause wrinkles more than necessary, so that it does not give the wearer uncomfortable feeling', and can improve novelty. (Flow linear). Furthermore, it is possible to avoid the occurrence of large wrinkles in the absorbent body due to the abrupt movement of the wearer. &lt; Embodiment of diaper type II &gt;

Fig. 9 is a perspective view of an embodiment of a pant-type diaper. Fig. 10 is a plan view showing the state of elongation of the pant diaper shown in Fig. 9 before the constituents are viewed from the surface material side. FIG. 11 is a sectional view taken along the line XI_XJ in FIG. 10. Fig. 12 is a cross-sectional view taken along the line X &amp; XII_XH of Fig. 10; It can be seen from the comparison of Fig. I, Fig. 2, Fig. 3, and Fig. 4 (a) that the pants-type diaper 300 (for babies) shown in Fig. 7F has the same initial configuration as the pants-diaper 1 described above. In the pants-type diaper 300 and the pants-type diaper, the physical properties of the elastic members around the waist, the elastic properties of the waist periphery, and the flexural rigidity of the absorbent body are greatly different from each other in terms of 85556 -36-1224963. Among the constituent members or regions shown in FIGS. 9 to 12, in addition to the physical properties of the elastic members around the waist, the elastic characteristics of the waist periphery, and the constituent members and regions of the absorber, they are added to FIG. I, FIG. 2, _3, and * 4 (a), the same reference symbols are used, and descriptions thereof are omitted. A new reference numeral 332 is attached to the waist elastic member, a new reference numeral 309 is attached to the waist periphery, and a new reference numeral 323 is attached to the absorber. In addition, for the convenience of explanation, the illustration of the three-dimensional frills 26A and 26B is omitted in FIG. 10. Each of the waist elastic members 3 3 2 of the pant-diaper 3 0 0 is arranged at an average interval of less than 5 claws at the point around the waist 309, which is the same as the pant diaper 1 described above, but the waist circumference When the elastic member 332 doubles in extension, the stress is lower than 20 gf (19.6 cN). By selecting the physical properties and arrangement of the elastic member 332 around the waist in this way, even if the size of the pant diaper 300 has a wide range (for example, a weight of 12) "When the size is symmetrical to the wearer of kg), it can give the user a soft and soft touch. In this configuration, the waist elastic member 332 is provided at the waist periphery 309. The side portion of the absorbent body 20 has a comfortable feeling of being tightened only at a specific part ', and the side flap effect can be improved for the same reason as the above-mentioned pants-type diaper 1. In addition, the pants-type diaper in this embodiment In 300, the stress when the elastic member 332 around each waist doubled was 20 gf (19.6 cN) or less as described above, but when the stress is exceeded, the wearer and the wearer It is difficult for protectors to feel "soft" or "gentle" , Prone rubber marks on the skin of the wearer. Elastic member around the waist 3 3 2 The stress at twice the elongation takes into account 85556 -37-1224963 deviation or side leakage performance when worn, and is set to 10 gf (9.8 cN) to 20 gf (19.6 cN)

Elongation during diaper attachment. Also, similarly, the stress at 3 times the elongation is lower than that at twice the elongation.

The minimum elongation required for a cloth or diaper. This is because when the stress is twice as high as twice the elongation, it is difficult to put on and take off. The optimum stress at this three-times elongation is specifically 35 gf (34.3 cN) or less, and more preferably 30 gf (29-4 cN) or less. In the above, for example, when the "double extension" is set to the original length A, it is extended to a length of 2A. In addition, the individual stretching stresses of the waist elastic members used in the diaper are obtained, and the waist elastic members 332 are taken out of the diaper product. When fixing with an adhesive, remove the adhesive completely with an organic solvent such as chloroform. Then, under the condition of a test speed of 300 mm / min, the S-S curve of the elastic member 3 3 2 around the waist was measured by an electronic theoretical universal testing machine, and the stress at each elongation was measured. Furthermore, each of the waist elastic members 3 3 2 is arranged so that the average interval is 5 mm or less. Therefore, in order to prevent the pants-type diaper 300 from falling off the wearer's body, it is necessary to ensure that the required number of waist-peripheral elastic members 332 are disposed at the waist-peripheral portion 309. In addition, since the waist elastic member 332 is two sheets, that is, between the non-woven fabric 24 A covering the legs and the outer layer of non-woven fabric 85B-85552-38-1224963, the so-called "fall-off" of the waist elastic member 332 can be prevented. , And can be fixed. In the pants-type diaper 300 according to this embodiment, the wearer's waist is comfortable with moderate stress so as not to fall off, and according to need, from the viewpoint of preventing the diaper fastened around the wearer's waist from falling, The stress at the time when the waist circumference elastic portion 309 of the waist circumference elastic member 332 is stretched by 80% as a whole is set to 400 to 800 gf (3.92 to 7.84 N), particularly 500 to 700 § £ (49 to 6 86 N). good. The "stress at 80% elongation" can be measured by the same method as described in the pant diaper i. In this embodiment, two non-woven fabrics, that is, a non-woven fabric 24A covering the legs and an outer non-woven fabric 24B are used to fix the waist elastic member 332. In this way, since the two sheets of the elastic member 332 fixed around the waist are made of non-woven fabric, it does not hinder the stretchability around the waist, which can provide the wearer with a soft touch and can purchase the board material at a low price. . Therefore, the pants-type diaper 300 according to this embodiment sets the stress at the time of elongation of each waist elastic member 332 below a specific value while selecting an appropriate material, so that the stress of the entire waist periphery 309 is maintained. In a specific range, the diaper of the wearer can be prevented from falling off, and the problem of rubber marks can be prevented from occurring in the first place, and the wearer can feel "softness" or "gentleness". In this embodiment, in order to effectively obtain the above-mentioned effects, a waist elastic member (specifically, the fineness is less than 39 dtex, and most preferably less than 3 10 dtex) is used as the waist circumference. Elastic member. In order to stably fix 14 kinds of fine elastic members, and to give the diaper a soft touch and vision, 85556 -39- In this embodiment, the following methods (5) to (5) are provided. ⑴ Use two base plates with a basis weight of 1G to 3G g / m2 to hold the fixed elastic member. (2) At least one of the above two sheets # is such that the average thickness (average fineness) of the resulting fineness is 4.5 dtex &amp; (preferably less than 101). Tianyu uses hot-melt adhesives of styrene-butadiene-styrene-isobutylene copolymers, styrene-associated fluorene, and pentadiene-styrene copolymers. ⑺Apply an adhesive of 咖 %% 2 (even the most suitable) to the elastic member, and fix and fix the two sheets. (5) Apply an adhesive agent 'on at least one of the two sheets holding the fixed elastic member, and set the coating amount to 1 to 8 g / m2. By providing the above methods (1) to (5), the elastic member 332 around the waist is strengthened, and the elastic member will not fall off even if the wearer performs fierce movements. Furthermore, in combination with the frills (the ruffles around the waist 10) generated by arranging the thin elastic members at a short pitch, it is possible to provide a soft feel to the diaper. The pants-type diaper 300 of this embodiment can be manufactured using the same method as the pants-type diaper i mentioned above. Surface material 21, leak-proof material 22, absorber 323, three-dimensional frilled elastic members 29A, 29B, leg elastic members 30A, 30B, waist elastic member 31, waist elastic member constituting the diaper 300 332. The non-woven fabric 24A covering the legs and the outer non-woven fabric 24B and the adhesive can be the same as those described in the pants-type diaper 1. However, the absorbent body 323 may be one having a higher bending rigidity than the absorbent body 23 described above. Although the above description is about the best embodiment related to the pants type diaper II of the present invention, 85556 -40-1224963 2 is the pants type diaper of the present invention. It is not limited to the five application modes disclosed in this specification. Appropriate changes can be made within the scope of the gist or idea disclosed in the entirety of the anti-patent application and the specification. However, pants with such changes are also included in the technical scope of the present invention. Pant-type diapers, the stress when the elastic members around the waist are twice as long as 20gf (19.6cN), and the stress when the times are three times as long as the stress when they are twice as long, The interval p between the elastic structures is set to be less than 5 mm and is arranged between the two plates, so that the wearer can feel "soft" or / 皿 本 "around the waist of the wearer in a large size range, and Reduces rubber marks. Then, while preventing permeation and contamination of the excreta in the side leakage portion of the waist periphery, the excreta will not leak out from the opening 4. In addition, the method described above can be achieved stably without causing the elastic members around the waist to fall off even if the diaper constituent materials and manufacturing steps are performed in a wide range of sizes. &lt; Embodiment of pants-type absorbent article> Fig. 13 is a perspective view schematically showing an embodiment of the pants-type absorbent article of the present invention. FIG. 14 is a composition diagram viewed from the side in contact with the wearer's skin. A plan view of the state before the pant-type absorbent article. FIG. 15 is a schematic view of a sectional view taken along line xv xv of FIG. Fig. 16 is a schematic view of a sectional view taken along a line. The pants-type absorbent article 400 shown in the figure above is a pants-type diaper (hereinafter referred to as a pants-type diaper 400). The pants-type diaper 400 is shown in FIG. 9, FIG. 10, FIG. 1 and FIG. By comparison, it can be seen that it has the same configuration as the aforementioned pant-type diaper in appearance. 85556 -41-1224963 In the pant diaper 400 and the pant diaper 300, in addition to a few differences in elastic characteristics around the waist, the application patterns of the adhesives holding the two plates that fix the elastic members around the waist are also different. In addition to the constituent members or regions shown in FIGS. B to 16, the same reference signs as those used in FIG. 9, FIG. 10, FIG. Reference symbols are omitted, and descriptions thereof are omitted. Around the waist, Shao added a new reference symbol Toru. In addition, in Fig. 14, the illustrations of the three-dimensional frills 26A and 26B are omitted for convenience. The elastic member 332 around the waist of the pant diaper 400 shown in the figure requires a load that is twice as long as 丨 9.6 cN / strand (converted as gf to 2〇§ £ / strand), and even three times as long. Elastomers with a required load equal to or less than twice the above-mentioned elongation are most desirable, especially when the required load is twice 19.6 CN / strand and the required load is three times as large. Elastomers with a maximum of 4 4 _ (converted by gf to 30 gf / strand) are ideal. Specifically, for an elastomer having a fineness of 390 dtex or less, for example, "⑽" (trade name), manufactured by DU-PONT TORAY CO., LTD., And Asahi Kasei Corporation can be used. "Roica" (trade name: registered trademark, "Silver Queen" (trade name: registered trademark), etc., manufactured by ASAHITEC Co., Ltd.) is not limited to this. The waist elastic member 332 is attached to the pants. The directions are arranged at intervals of less than 5, and the number is selected so that the waist circumference is completely stretched. _ The required load is selected from 2 N to 8 N. It is selected to be 4 prostitutes and 7 N. Here, in the present embodiment, the so-called "load required to be 11 times (11 series 2 or 3) 85556 -42-1224963 weight" refers to the natural state of the elastic body used as the elastic member 332 around the waist (not applied) When the length of the state of tension) is set to 丨, it means that the length of the elastic body is set to the load required by η. Also, "the waist circumference is extended by 80%" means that only the waist circumference is cut out under a ring-shaped complaint. 409, the body width direction when the waist circumference portion 409 is extended to the maximum in the body width direction The length is set to 100%, and the body width direction is extended to 80% of the length. The pants-type diaper 400 is the same as the pants-type diaper of each embodiment described above, and the non-woven fabric covering the legs is made of an adhesive. 24Α and outer layer non-woven fabric 24B are fixed to each other, and the elastic members 3 3 2 around each waist can also be found in the state of stretch elasticity. In the extended state, the non-woven fabric 24A covering the legs and the outer layer non-woven fabric 24Β The above-mentioned adhesives are from the viewpoints of simplification of manufacturing steps and securing of adhesive strength. Although a hot-melt adhesive is preferred, the present invention is not limited to this, and vinyl acetate can also be used appropriately. , Petroleum resin, cold glue (cold glue), etc. Also, the basis weight (applied amount) of the adhesive is lower than the area in the area where the absorber body 20 is fixed to the diaper 400. The surroundings are selected in more ways. The basis weight of the above adhesive under the area where the absorber body 20 is fixed is selected from 1 to 10 g / m, especially in the range of 2 to 8 g / m2. The adhesive on the left and right sides of the region The basis weight is preferably from 1 to 12 g / m2, and most preferably from 2 to 10 g / m2. In the pant diaper 400 having the above-mentioned distribution on the basis weight of the adhesive, the following (1) to ( The method of 2) is quite effective for fixing the waist elastic member 332 to a desired position even when the diaper is used. 85556 -43- 1224963 Fixing the waist elastic member (1) Use a basis weight of 10 to 30 g / The m2 is used as the two sheets of the holding member 3 3 2. (2) At least one of the two sheets mentioned above uses a fineness of 4.5 dtex, and more preferably 2.0 dtex or less. In the pants-type diaper having the above configuration, the waist elastic member 332 having a low rate of increase in shrinkage stress relative to the increase in elongation is arranged at a narrow interval around the waist, so that the waist can be easily expanded when worn. Opening Shao 5. That is, the usability is excellent. In addition, since the distribution of the shrinkage stress of the waist elastic members 332 in the waist region 409 as a whole is difficult to deviate during wearing, the waist circumference is changed by the wearer's posture or movement, and the waist region 409 is changed. The elongation increases. As a result, giving the wearer a strong tie 'can suppress the occurrence of rubber marks. That is, the wearing feeling is excellent. In addition, sufficient shrinkage stress can be obtained by preventing the entire waistline portion 409 from dropping. As described above, by selecting the basis weight (application amount) of the adhesive, each waistline can be reliably secured even during wearing. Since the elastic member 332 is fixed at a desired position, it is possible to easily prevent leakage from the abdomen or the back, and to prevent the pants-type diaper 400 from falling off or taking off easily. When the pant-type diaper 400 is used for infants, a pant-type diaper which is difficult for infants to take off by themselves is obtained. As described above, the basis weight (applied amount) of the adhesive can securely fix each waist elastic member 332 at a desired position even during wearing. The touch and the softness are reduced, so the above-mentioned points can also improve the wearing feeling of the pants-type diaper 400. Furthermore, the effect of preventing side leakage of the peripheral portion 409 of the waist 85556 -44-1224963 is improved for the same reason as the aforementioned pant-type diasoo. The pants-type diaper 400 that achieves the above-mentioned technical effects is substantially free of frills (wrinkles) on the absorbent body 20, so that its appearance can be the same as that of ordinary underwear. In addition, as described later, it is desirable to apply an oil to a long-length elastic body which is a material for the elastic member 332 around the waist when the pant-type diaper 400 is manufactured. When the oil agent is applied, a pant-type diaper 400 having an oil agent on the surface of the elastic member 332 around the waist can be obtained. The absorbent body 23 is preferably one having a saturated absorption capacity of more than 500 g. &lt; Embodiment of manufacturing method of pant-type absorbent article &gt; Figs. 17 to 19 each schematically show a manufacturing step of the pant-type absorbent article of the present embodiment. In the following, the above-mentioned pants-type diaper 400 is used as an example, and the reference symbols used in Figs. 13 to 16 are appropriately referred to, and the embodiment of the manufacturing method will be described in detail. First, as shown in FIG. 17, the belt-shaped i-th plate material 50 of the outer layer non-woven fabric 24B is moved by a Wan-type conveyance that moves the first material 50 in the longitudinal direction, and the i-th plate material 50 is passed through the first} The roll coater 52 continuously applies the adhesive 54 on the 409 &lt; area of the waist which becomes the pants-type diaper 4 in the direction of the long side of the plate material 50 for the first step. In Fig. 17, an arrow a indicates the conveying direction of the second plate material. The type of the adhesive 54 used in the first step is a pants-type absorbent article: The description of the application form is as follows. In addition, the coating amount is selected from 丨 to [0 g / m2, and particularly preferably selected from a range of 2 to 8 g / m2. Step 2 is performed in parallel or back and forth. In the second step, prepare a known long-length elastic body that becomes the elastic member 332 around the waist, and apply oil to the above-mentioned elastomers as shown in FIG. 17, as shown in FIG. 17, respectively. An adhesive (not shown) is applied to the elongated elastic body 56 intermittently in the longitudinal direction by the second roll coater 58. The long elastic body 56 serving as the waist elastic member 332 is as described above. Since the fineness is small, it is easy to break due to the friction of the device during the guidance to the desired position. Therefore, it is speculated that it is impossible to apply such an elastomer to a diaper. In this embodiment, by applying an oil to the long-length elastic body 56, it is possible to prevent the breakage and it can be applied to a diaper having a percentage of the long-length elastic body. The oil agent applied to the elongated elastic body 56 can be, for example, silicone oil, hydrocarbon oil, mineral oil, etc., and the application method thereof can be, for example, an impregnation method, a spray grid rotation method, or the like. In the application of the grievance, a method of immersing the long-length elastic body 56 in oil beforehand is applied. The oil agent is relative to the weight of the long-length elastic body 56, and it is preferable to apply it in an amount of 0.5 to 6 wt./%, especially in a range of 1 to 5 wt.%. In this way, by applying the oil, it is easy to surely cut the long-length elasticity to 5 6 ′ in the fourth step described later, and it is possible to easily fix the waist elastic member w 2 at a desired position. In addition, even if the application amount of the adhesive used in the first step is the above-mentioned amount, the waist elastic member 332 can be surely fixed at a desired position ', so that it is easy to maintain the touch of the waist 401. Furthermore, when the elastic member 3 3 2 around the waist is formed and the long-length elastic body 56 is cut off locally, even if a small piece of the elastic body 56 remains on the absorber body 20, the small piece is disengaged from the first The sheet material 50 or the second sheet material 62 shrinks due to adhesion and fixation. Since the shrinkage is not observed, the small piece does not shrink the absorber body 20 by 85556 -46-1224963. In the second step, the adhesive applied to the long-length elastic body 56 may be the same as that used in the first step. In the case of using two sheets of non-woven two-layered body 24, from the standpoint of adhesiveness, it is most preferable to use a hot melt adhesive. Θ This adhesive is not applied to the area below the central area in the width direction of the absorber body 20 in the fifth step described later, and is applied intermittently as described above because it is applied to the: area. The interval between the adhesive-coated area and the non-adhesive-coated area is preferably set to 20 to 80% of the body width of the pants-type diaper 400, and it is particularly preferable to set it within a range of 30 to 60%. . In this case, it is preferable that the area where the adhesive is applied is designed so as to overlap the left and right side edges of the absorber body 20 of the waist periphery portion 409. At this time, although the weight and the width of the mouth knife are less than 20% of the maximum width of the waist circumference 4 009 of the absorber body 20, and in particular 10% or less, the absorption performance is not reduced. Without compromising the best appearance. Considering the adhesiveness and the tactile sensation around Shao 409 around the waist, in the second step, the area where the adhesive is actually applied knows that the application amount of the adhesive is best selected in the range of 10 to 50 g / m2. In addition, the elastic body 60 serving as the waist elastic member 31 is coated with a hot-melt adhesive by a coating means (not shown). Arrow B in the figure indicates the conveying direction of the elastic bodies 56 and 60. -After performing the first step and the second step, as shown in FIG. 17, the long-length elastic body 56 that has been subjected to the second step is held and fixed to a belt-shaped belt covered with a non-woven fabric 2 4 A. Step 2 between the second plate material 6 2 85556 -47- step. The arrow C in the figure indicates the conveying direction of the second plate material 62. In the example shown in the figure, a pair of lepton 64 passes through a plate material 50, a long-length elastic body ^ serving as a waist elastic member 332, an elastic body 60 serving as a waist elastic member 31, and The second plate material 62 holds and holds the elastic bodies 56 and 60 between the first plate material 50 and the second plate material 62. In this case, it is preferable that the elongated elastic bodies 56 are each set to have an elongation between 100 and 500 ¾. In this embodiment, the elongation of 250% is fixed. In addition, the elongation referred to herein is a value expressed by [(L1-L) / L] x100% when the length of the elastomer is L and the length at the time of extension is L1. Similarly, the elastic body 60 serving as the waist elastic member 31 is preferably fixed at an elongation of 50 to 200 ° / °. In this embodiment, it is fixed at 100% elongation. In the laminated body obtained in the third step, since the adhesive is applied to the long-length elastic body 56 intermittently, the application amount of the adhesive is distributed. That is, in the region where the absorber body 20 is fixed in the fifth step described below, the adhesive is not applied to the long-length elastic body 56 and the application amount of the adhesive is less than that around the region. the amount. The second plate material 62 may or may not be coated with an adhesive. When the adhesive is applied, the entire second plate material 62 may be applied, and when the pant diaper 400 is produced, it may be applied only to the areas on the left and right sides of the absorbent body 20. When the adhesive is applied to the second plate material 62, the application amount combined with the adhesive applied to the first plate material 50 is applied on the entire surface of the board so as not to damage the tactile and visual sense of the waist circumference 409. It is preferable to select this coating amount so that it may become the range of 1-10 g / m2. 85556 -48-1224963 Do not apply adhesive to the second board material 62, because the lower part 4, waist part 7, and waist circumference part 4 of the panty diaper 400 equivalent to the pant diaper 400 on the 50th sheet material 50 The area Wang Shangtang was coated with an adhesive 54 ′, so it was approximately fully bonded with the second work material 62 and the second work material 62. Since there is practically no gap between the two plate materials: EJ can obtain an outer layer body 24 without a soft and fluffy touch. In addition, the elastic bodies 56, 60 are fixed at the first! The step m of the plate material 50 and the step m of holding the elastic body 56 and 60 between the i-th plate material 50 and the second plate material ^ are performed substantially simultaneously as shown in the figure, or they can be performed individually. . Although;, :: Figures are omitted in Figure 17, but the leg elastic members 3GA and 3GB constituting the trouser-type diaper are also passed in the third step-between the cymbals 64 and fixed on the j-th plate The material 50 and the second plate material α. The oil continues to the third step above. * As shown in FIG. 18, a plurality of tears are pressed from the outside of the first plate material 50 and the second plate material α on the areas where the long elastic m 56 is not coated with the adhesive, respectively. The raised member 66 performs a fourth step of cutting the area. In the example shown in the figure, a roller 68 composed of a first roller 68A having a plurality of protruding members 66 and a second roller 68b having a general shape is arranged in a thousand-bird shape at a specific place. In the third step, the first plate material 50 and the second plate material 62 are fixed to each other, and a plurality of protruding members 66 are pressed from the outside of the second plate material 62 to cut the area. In FIG. 18, in the long-length elastic body, the above-mentioned cut areas are indicated by dashed lines, and the other areas are indicated by continuous lines. X is used to realize the elasticity of 85565 -49- 4 waist elastic member 31.体 60。 The arrow D in the figure indicates the conveying direction of the first plate material 50 and the second plate material 62 which are fixed to each other in the third step. The opposite side is cracked. As a result, the heating is performed in the present embodiment. Each protrusion-shaped member is arranged in an elongated state: each of the long elastic bodies 56 of Mann is cut with a weak pressure. In this way, when the above-mentioned region is cut, it is possible to suppress a required pressing force from being applied to the first plate material 50 and the second plate material 62, so that it is possible to prevent the phase of the face of the protruding member from being pressed. This prevents the formation of diapers from damaging other members or giving the wearer an uncomfortable feel. When the crying member 66 is heated, the temperature of the protruding member M is 30 to 20 ° C. Especially 50 to 120 ° C is the best. The linear pressure applied by the crying member 66 is preferably i N / mm to 1 MN / mm, and more preferably 50 N / mm to 10 kN / mm. When the line pressure is set to 50 N / mm or more, the cutting of the long-length elastic body 56 is extremely stable. When the line pressure is set to N kN / mm or less, it is caused by the i-th plate material 50 and the second plate material 62. The strength P low is 'significantly restrained from breaking at the boundary portion between the pressurized portion and the non-pressurized portion. Then,' the first plate material 50 or the second plate material 62 is fixed to the first plate material 50 and the first 5 steps. In the example shown in the figure, since the second plate material 62 is a non-woven fabric 24A covering the legs, the absorber body 20 is fixed to the second plate material 62. As shown in FIG. 19, the fixed body of the absorber body 20 is arranged on the way &amp; a pair of first rollers 72 is used to send the laminated body 70 obtained in the fourth step to the figure indicated by an arrow E Show the direction. The absorber body 20 is connected to a plurality of ribbons 74 and is provided for the first cutting. 85556 -50- several are separated one by one in this order. Then, the separated absorbent bodies 20 are sequentially supplied to the rollers 72A on one side of the first roller 72, respectively. The arrow F on the way indicates the conveyance direction of the ribbon 74. The roller 72A attracts the provided absorbent body 20, changes its direction to the special direction I, and then interposes a laminate 70 between the other rollers 72B to hold the absorbent body 20. This absorber body 20 is fixed to the laminated body 70. After the absorber main body 20 is fixed by this method, as shown in FIG. 19, the leg openings 6A and 6B are formed by the second roller 80, and then the second cutting machine 82 is used to sequentially An area 84 corresponding to one pants-type diaper 400 is cut out. In a specific place of each area 84, that is, a place corresponding to both side portions 2A, 2B (see FIG. 14) of the ventral portion 2 of the pant-type diaper 400, and both side portions corresponding to the back side portion 3A and 3B (refer to FIG. 14), the pants-type diaper 400 mentioned above can be obtained. In addition, in the pants-type diaper 400 described above, it is not necessary to arrange all the waist elastic members 332 according to the above embodiment. For example, a part of the waist elastic members 332 may be disposed in the absorber body 2. 5 waist openings. In this case, the elastic member 332 around the waist disposed on the side of the waist opening 5 of the absorber body 20 may be partially cut, and may be continuous without being cut. In addition, the waist elastic member 332 is only disposed outside the side edge portion of the absorbent body 20, and is within a range not exceeding the spirit or idea of the present invention. 〇 The side parts may be arranged so as to overlap. The three-dimensional frill system is not limited to one pair, and two pairs can also be set. When two pairs are set, 85556 -51-1224963 can make one pair only exist across the lower part 4. Although the description of the embodiment of the pants-type absorbent article of the present invention is described by taking a pants-type diaper as an example, the pants-type absorbent article of the present invention is not limited to pants-type diapers, and may be applied to other pants. Type absorbent article 'such as a pant type physiological article. The above embodiment can be applied to a pant-type physiological article. In addition, operators can make various changes, improvements, and combinations. Hereinafter, the example is described in detail for the pants-type absorbent article of the present invention. <Example 4 to Example 6> According to the embodiment of the manufacturing method of the pants-type absorbent article of the present invention described above, the same characteristics were obtained except that the elastic characteristics of the elastic members around the waist and the elastic characteristics of the waist were different. There are three types of pants-type diapers with a waist width of 40 and a waist-peripheral width of 80 mm in the planting direction. At this time, the knife uses a spunbonds non-woven fabric with a basis weight of 20 g / m2 as the first board material, a spunbond non-woven fabric with a basis weight of 25 g / m2 as the second board material, and uses a shaving adhesive as an adhesive and silicone. Oil is applied to a long-length elastic body which becomes a single f member around the waist. The interval between adjacent waist elastic members is 4 mm. The elastic properties of the elastic members around the waist of the pants-type diapers produced by each of the examples are shown below. The elastic characteristics of the waist and the size of the oil during the production are expressed by the amount of the adhesive applied by Yu and Temple. Table 4 shows the appearance value of the appearance of each pants type diaper in Table 5. <Comparative Example 5 to Comparative Example 13> 85556 -52- 丄 224963 Elastic reduction of elastic members around the waist ㈣ Characteristics Interval of waist elastic members, :: Elastic characteristics of rounds, application amount of oil and adhesion The application amount of the agent is out of the range of the soil-type absorbent article of the present invention, and the rest are made in the same manner as in Example 4 to Example 6 to produce the pants type of Examples 4 to 6. The diaper has a pants-type diaper of the same structure.
