According to one or more embodiments of the present invention, since the main body and the side sheets are joined to each other by the connecting sheets, the side sheets are not easily broken as compared with the case where the side sheets are directly joined to the main body. . Therefore, it is not necessary to increase the rigidity of the side sheets, and the flexibility can be maintained.

[Formation for carrying out the invention] <First embodiment>

1 to 4 show a first embodiment of the present invention. Referring to FIGS. 1 to 3, the disposable diaper 1 has a longitudinal direction Y and a lateral direction X, and has a main body 10 having a front waist region 11 and a rear waist region 12 positioned between the front and rear waist regions 11, 12 The crotch region 13, the front and rear end edges 14, 15 extending in the lateral direction X, and the side edges 16 extending in the longitudinal direction Y; and the side sheets 70 connected to the main body 10 via the connecting sheet 80.

The disposable diaper 1 has an imaginary longitudinal center line 2-2 which divides the size of the lateral direction X into two equal parts, and is almost symmetrical at the imaginary longitudinal center line 2-2. Regarding the same constituent elements that are set to be symmetrical, a part of the symbols are omitted from the drawing.

The main body 10 includes: an inner sheet 20 which is liquid-permeable to the opposite surface of the skin; an outer sheet 30 which is located on the opposite side of the non-skin opposite surface; and is located between the inner and outer sheets 20, 30 The absorber 40; and a liquid-impermeable or liquid-impermeable leakage preventing sheet 50 located between the absorber 40 and the outer sheet 30. The skin facing surface of the inner sheet 20 is disposed with a lateral X score. A pair of blocking sheets 60 that extend away from the longitudinal direction Y.

For the inner sheet 20, for example, a mass of about 15 to 35 g/m ² can be used, and it is preferable to use a hydrophilic treated spunbonded fiber nonwoven fabric or a point-bonded non-woven fabric of about 18 to 23 g/m ² . For the outer sheet 30, for example, a hydrophobic spunbonded spunbond (hereinafter referred to as SMS) fiber non-woven fabric or spunbonded nonwoven fabric having a mass of about 10 to 30 g/m ² can be used. The inner sheet 20 has its front and rear end edges 21, 22 almost coincident with the front and rear end edges 31, 32 of the outer sheet 30, and the side edges 23 of the inner sheet 20 are located more laterally than the side edges 33 of the outer sheet 30. Inside party. That is, the inner sheet 20 is set to have a smaller dimension of the lateral direction X than this of the outer sheet 30.

For the sealing sheet 60, for example, a hydrophobic SMS fiber nonwoven fabric or a spunbonded nonwoven fabric having a mass of about 10 to 30 g/m ² can be used. The front and rear end edges 61, 62 of the blocking sheet 60 are almost identical to the front and rear end edges 21, 22 of the inner sheet 20 and the front and rear end edges 31, 32 of the outer sheet 30, the front and rear end edges 61, 62 and the front and rear end edges 21, 22 is joined to each other by a known joining means such as a hot-melt adhesive (not shown). The proximal edge portion 63 of the blocking sheet 60 is joined to both side edges 33 of the outer sheet 30 by well-known joining means such as a hot-melt adhesive. The distal edge portion 64 of the blocking sheet 60 overlaps only the inner sheet 20 in a tension state toward the longitudinal direction Y shown in FIG. At the distal edge portion 64, the elastic body 65 extending in the longitudinal direction Y is retractably mounted in an extended state. By the contraction of the elastic body 65, the distal edge portion 64 is separated from the inner surface sheet 20 toward the wearer's skin side, and is in close contact with the thigh, and the excrement such as stool is sealed inside the sealing sheet 60.

The absorbent body 40 can achieve its function as long as it is at least in the underarm region 13, but in this embodiment, it is extended from the underarm region 13 toward the front and rear waist regions 11, 12, and absorbs urine in a relatively wide range. Excrement. The absorber 40 is composed of a liquid-absorbent core material and a liquid-diffusing cover sheet such as a thin paper covering the core material. Wood fluff pulp, superabsorbent polymer particles, or a mixture of these may be used as the core material. The core material and the coated sheet can be joined to each other by a well-known joining means such as a hot-melt adhesive which is not shown, and which does not impede the absorption function of excrement such as sufficient urine of the core material.

The leakage preventing sheet 50 is joined between the coated sheet of the absorbent body 40 and the outer sheet 30 by a known joining means such as a hot-melt adhesive which is not shown. The leakage preventing sheet 50 can be made of a liquid impervious film, and is preferably a liquid-impermeable and air-permeable plastic film. Since the leakage preventing sheet 50 has a larger area than the absorbent body 40, it is possible to prevent excretion of urine or the like absorbed by the absorbent body 40 from leaking to the outside of the disposable diaper 1.

The leg elastic body 51 is attached in the vicinity of the side edge of the surface opposite to the surface of the outer sheet 30 opposite to the leakage preventing sheet 50. The leg elastic body 51 is joined between the leakage preventing sheet 50 and the blocking sheet 60 by a well-known joining means such as a hot-melt adhesive which is not shown. The leg elastic body 51 extends in the crotch field 13 along the both side edges 16 in the longitudinal direction Y, and the first end edge 51a on the side of the front waist region 11 extends to the front waist region 11, and is located on the side of the rear waist region 12 The 2 end edge 51b extends to the rear waist region 12, and is retractably mounted in a state of being elongated toward the longitudinal direction Y. In the case of the leg elastic body 51, a plurality of linear or strip-shaped elastic bodies can be used. By the leg elastic body 51, in the outer field of the absorber 40 An elastic flank having a gasket function is formed.

In the rear waist region 12 of the main body 10, a pair of side sheets 70 are attached to the side edges 16 thereof via the connecting sheets 80. As the connecting sheet 80, for example, a hydrophobic spunbond nonwoven fabric having a mass of about 40 to 60 g/m ² , an SMS fiber nonwoven fabric, or the like can be used. Referring to Fig. 4, the connecting sheet 80 has an outer region 81 to which the side sheets 70 are joined, an inner region 82 joined to the main body 10, and an intermediate portion 83 positioned therebetween. The inner region 82 is fixed between the sealing sheet 60 and the outer sheet 30 by the joint portions 86, 87 using a known joining means such as a hot melt adhesive. The main body 10 and the side sheets 70 are separated in the lateral direction X across the intermediate portion 83. In the intermediate portion 83, since only the connecting sheet 80 exists, the rigidity is lower than that of the other regions, and the rigidity is poor. Due to the difference in rigidity, the connecting sheet 80 is easily bent across the intermediate portion 83, and the side sheet 70 can be easily adhered to the wearer's skin when worn. As long as such an effect can be obtained, the main body 10 and the side sheets 70 can also be in a state of no overlapping contact with each other. The outer region 81 is fixed to the side sheet 70 by a joint portion 84 using a well-known joining means such as a hot melt adhesive.

The side sheet 70 includes a first sheet 71 positioned on the opposite side of the skin, a second sheet 72 positioned on the non-skin opposing surface, and a plurality of elastic bodies 73 attached between the sheets. In the case of the elastic body 73, for example, a linear or strip-shaped elastic body having a thickness of about 470 to 700 dtex can be used, and the transverse direction X is elongated by about 2 to 3 times, and the longitudinal direction Y is set to be about 5 to 15 mm. . In this embodiment, the use of about 620 dtex as the elastic body 73 is arranged at a pitch of about 10 mm in the longitudinal direction Y, and is oriented in the lateral direction X. The elongation is about 2.6 times to be installed. Further, the pitch means a distance from the center of the adjacent one of the elastic bodies to the longitudinal direction Y of the center of the other elastic body.

The first and second sheets 71 and 72 are almost the same size, and for example, a hydrophobic SMS nonwoven fabric having a mass of about 10 to 30 g/m ² can be used, and a well-known joining means such as a hot-melt adhesive having no pattern can be used. Being joined to each other. The first and second sheets 71 and 72 and the connecting sheet 80 are actually non-elongated fiber nonwoven fabrics. "actually non-elongation" means that the elastic diaper is not provided, and when the disposable diaper 1 is used, at least the normal force is pulled in the lateral direction X, and the waist opening of the left and right disposable diapers 1 is not used. Such a size of the surrounding size setting causes a change.

By attaching the elastic body 73 to the first and second sheets 71 and 72, the side sheet body 70 is formed with an elastic region 74 that is elastically expandable and contractible in the lateral direction X, and the outer side of the elastic region 74 in the lateral direction X. The inner and outer inelastic regions 75, 76 that are elastically stretchable and separated from each other in the lateral direction X. The elastic body 73 extends from the elastic region 74 toward the inner and outer inelastic regions 75, 76, and the end portions 73A, 73B are located in the inner and outer inelastic regions 75, 76. The inner inelastic region 75 is fixed to the outer region 81 of the connecting sheet 80, and the outer inelastic region 76 is fixed between the first and second tongue sheets 91 and 92. A hook element 95 is attached to the first tongue piece 91.

The inner and outer inelastic regions 75, 76 of the side sheet 70 can be formed by the following method. That is, the elastic body 73 is attached in an extended state even in any of the elastic region 74 and the inner and outer inelastic regions 75, 76. In the inner inelastic region 75, a well-known joining means such as a hot melt adhesive is used. The joint portion 84, the second sheet 72 is joined to the outer region 81 of the connection sheet 80. Since the bonding portion 84 is coated with an adhesive, the rigidity is higher than when the coating is not applied. In the joint portion 84, the first and second sheets 71 and 72 and the elastic body 73 are overlapped and joined. In the side sheet body 70, although the elastic body 73 is retractably attached in an extended state even in the inner non-elastic region 75, the second sheet 72 may be joined to the connecting sheet 80 via the joint portion 84, and the overlap may be performed. The portion is made to have high rigidity, and the elastic body 73 can be formed so as not to be stretchable, and the inner inelastic region 75 is formed. Similarly, in the outer inelastic region 76 of the side sheet 70, the second sheet 72 is joined to the second tongue piece 92 via the joint portion 93. At the joint portion 93, the end portion 73B of the elastic body 73 of the side sheet body 70 is overlapped and located there. Since the elastic body 73 which is superposed on the joint portion 93 is restrained from being stretched and contracted, it is practically impossible to expand and contract. Therefore, the outer non-elastic region 76 is formed in a region overlapping the joint portion 93. The joint portion 93 is formed by a well-known joining means such as a hot melt adhesive.

By forming the inner and outer inelastic regions 75 and 76, it is not necessary to perform such a process of cutting the elastic body 73 in order to inelasticize the inner and outer end portions of the elastic body 73 attached in the extended state, and compared with It is easy to form by such a method of engineering. Further, by joining the inner and outer inelastic regions 75, 76 to the connecting sheet 80 and the second tongue sheet 92, the joint strength can be enhanced and the joining can be made stronger than when the elastic regions are joined. In the inner and outer inelastic regions 75, 76, wrinkles are less likely to occur than the elastic regions 74, and the sheets can be joined to a wider area.

In the side sheet 70, the first and second sheets 71, 72 are passed through The joint portions formed by the hot-melt adhesive or the like of the unillustrated form are connected to each other, and the elastic body 73 is also fixed to at least one of the first and second sheets 71 and 72 via the joint portion. In order to prevent the both ends 73A and 73B of the elastic body 73 from falling off, the amount of application of the adhesive can be increased. The joint portion between the first and second sheets 71 and 72 and the joint portion 84 overlap each other, and the dimension of the lateral direction X of the overlapped region can be, for example, 10 mm or more. Similarly, the joint portion between the first and second sheets 71 and 72 and the joint portion 93 overlap each other, and the dimension of the lateral direction X of the overlapped region can be, for example, 10 mm or more. By the fact that the joints overlap each other, the rigidity of the overlapped region is increased to make the joint stronger. Further, the side sheets 70 stacked on the joint portion 84 and the joint portion 93 are disposed such that the end portions 73A and 73B of the elastic body 73 are extended.

A non-joining portion 85 is formed outside the lateral direction X of the joint portion 84 of the connecting sheet 80, and the outer edge of the second sheet 72 and the connecting sheet 80 can be separated. Similarly, the non-joining portion 94 is formed outside the joint portion 93 of the second tongue piece 92 in the lateral direction X, and the inner edge of the second sheet 72 and the second tongue piece 92 can be separated.

2 and 3, the first and second tongue pieces 91, 92 extend in the longitudinal direction Y and protrude outward in the lateral direction X, and a plurality of tongues 96 which are separated from each other in the longitudinal direction Y are formed. The tongue pieces 96 are each mounted with a hook element 95. Therefore, the hook element 95 is disposed to be separated in the longitudinal direction Y. As the first and second tongue sheets 91 and 92, for example, a spunbonded nonwoven fabric having a mass of about 40 to 60 g/m ^{2 or} an SMS fiber nonwoven fabric can be used.

As shown in Figure 1, by hooking the hook element 95 that constitutes the fastening system The desired area of the fiber nonwoven fabric of the outer sheet 30 of the system constituting the front waist region 11 is joined to the front and rear waist regions 11, 12 for wear by the wearer. The hook element 95 of this embodiment forms the second connecting element of the invention, and the outer sheet 30 of the front waist region 11 forms the first connecting element of the invention. By using the outer sheet 30 as the first connecting element, the first connecting element is formed in the entire lateral direction X from one side edge 16 to the other side edge 16 , and the hook element 95 can be connected to the non-skin pair of the main body 10 . Any position to the face. Since the hook element 95 can be coupled to a wide range of the front waist region 11, the front and rear waist regions 11 and 12 can be coupled to the wearer in conformity with the wearer's body shape and body state. Moreover, since the outer sheet 30 is used as the first connecting element, since no other member is required, such a manufacturing cost can be reduced. The fiber non-woven fabric forming the first connecting element may be located in a part of the front waist region 11 or may be positioned substantially in the entire front waist region 11.

In the disposable diaper 1 of the above type, the side sheets 70 are joined to the main body 10 via the connecting sheets 80. It is assumed that when the side sheet body 70 is directly fixed to the main body 10, when the sheet body 70 is pulled toward the lateral direction X, the tensile force acts directly on the side portion of the side sheet body 70 fixed to the main body 10, and the side sheet body 70 is broken. Dropped or detached from the main body 10. However, since the connection sheet 80 is provided, since the tensile force acts via the connection sheet 80, it is possible to prevent the side sheet body 70 from being broken or falling off from the main body 10. It is assumed that when the side sheet 70 is broken, it is necessary to use a material having a relatively high mass and density which increases the rigidity of the side sheet 70. However, since it is not necessary, it can be made of a fiber having low rigidity and low flexibility. The material forms a side sheet 70.

The side sheets 70 are extended almost entirely in the longitudinal direction Y of the rear waist region 12, and the hook elements 95 are fixed to the lateral X outer side edges of the side sheets 70. Therefore, when the hook element 95 is coupled to the outer sheet 30 of the front waist region 11, the hook element 95 and its vicinity are overlapped with the front waist region 11, and most of the side sheet 70 is not overlapped in the front waist region. 11 situation. At this time, the side sheet 70 directly contacts the wearer's skin. In this embodiment, since the side sheet 70 is formed of a material having a relatively low rigidity and high flexibility, even if the side sheet 70 directly contacts the wearer's skin, it can be reduced. A disposable diaper 1 that is irritating to the wearer's skin and has a good touch.

In this embodiment, the outer sheet 30 constituting the main body 10 is joined to the sealing sheet 60 at the inner edge of the connecting sheet 80, and the elastic region 74 of the side sheet 70 is adjacent to the outer edge. The rigidity of the connecting sheet 80 is about 45 to 100 N/50 mm, and the rigidity of the main sheet 10 of the outer sheet 30 and the sealing sheet 60 is about 30 to 50 N/50 mm, and the rigidity of the elastic portion 74 is about 40 to 70 N/50 mm. The rigidity is set to the maximum. The connecting sheet 80 is joined to the side sheet body 70 at the outer side region 81, and joined to the main body 10 at the inner side portion 82, and the intermediate portion 83 between them is constituted only by the connecting sheet 80. When the side sheet 70 is pulled outward in the lateral direction X, and the hook element 95 is joined to the outer sheet 30 of the front waist region 11, the intermediate portion 83 of the connecting sheet 80 having the smallest number of laminated sheets is rigid compared to the outer inner portions 81, 82. Since the intermediate portion 83 is easily broken, the rigidity of the connecting sheet 80 is larger than that of the main body 10 and the side sheet 70, so that the side sheet 70 can be prevented from being broken from the intermediate portion 83. . rigidity The measurement is performed by the following method.

<Measurement method of rigidity>

The rigidity was measured using a stretching tester manufactured by Instron Corporation of Japan. The elastic region 74 and the inner inelastic region 75 were cut as a sample so that the longitudinal direction Y and the lateral direction X were each 50 mm. The elastic region 74 is formed of a sample piece containing the first sheet 71, the second sheet 72, and the elastic body 73, and the elastic body 73 is in a contracted state of 50 mm. A portion including the first sheet 71, the second sheet 72, the elastic body 73, the connecting sheet 80, and the joint portion 84 is used as the sample piece in the inner inelastic region 75. Each of the sample pieces was held by a pair of jigs of the stretching tester, and pulled at a pulling speed of 100 mm/min in a direction separating from each other, and the maximum strength at this time was taken as rigidity.

In the side sheet body 70, the elastic body 73 is attached between the first and second sheets 71 and 72 by a well-known joining means such as a hot-melt adhesive, but the position at the center of the elastic body 73 can be maintained. The coating quality of the agent is set to be smaller than this in the lateral direction X. With such a setting, it is possible to prevent the rigidity from being increased by the adhesive in the elastic region 74, and it is possible to secure this to the first and second sheets 71 and 72 at both end portions of the elastic body 73 as the prevention of elasticity. The body falls off. In this embodiment, the elastic non-stretchable fiber nonwoven fabric is used as the first and second sheets 71 and 72, and the elastic body 73 is attached between the sheets to elastically expand and contract the side sheet 70. Further, the elastic non-woven fabric of the elastic stretchable material can be used as the side sheet body 70. At this time, although it is not necessary to install the elastic body 73, it may be made. The elastic body is further attached to the stretchable fiber nonwoven fabric.

The non-joining portion 85 is formed in the connecting sheet 80, so that the outer edge of the connecting sheet 80 can be separated from the side sheet 70, and the elastic region 74 overlapping the side sheet 70 is formed. Similarly, the second tongue piece 92 is also formed with the non-joining portion 94, and the inner edge of the second tongue piece 92 can be separated from the side sheet 70 and formed to overlap the elastic region 74. The connecting sheet 80 and the second tongue sheet 92 positioned in the non-joining portions 85 and 94 can cover at least a part of the elastic region 74, and even if the elastic region 74 expands and contracts, since the sheets do not have expansion and contraction, they are elastic. When the expansion and contraction of the body 73 causes wrinkles in the elastic region 74, the wrinkles can be covered by the sheets positioned on the non-joining portions 85, 94, respectively. Since the connecting sheet 80 and the second flap sheet 92 are positioned on the non-skin opposing surface of the side sheet 70, the sheets prevent the wrinkles of the elastic region 74 from being caught in the wearer's clothing or between the clothing and the clothing. The situation where the friction becomes larger.

In this embodiment, the connection sheet 80 and the second tongue piece 92 are attached to the non-skin opposing surface of the side sheet body 70, but may be attached to the skin facing surface. At this time, the elastic region 74 of the side sheet 70 can be covered by the sheet positioned on the non-joining portions 85, 94, and the wrinkles of the elastic region 74 can be prevented from coming into contact with the wearer's skin to cause irritation. In the connection sheet 80, the dimension of the lateral direction X of the joint portion 84 is about 10 to 25 mm, and the dimension of the lateral direction X of the non-joining portion 85 is about 1 to 15 mm. The dimension X of the non-joining portion 94 of the second tongue piece 92 is about 1 to 15 mm.

Such a disposable diaper 1 can be suitably worn, for example, for adults who are bedridden for a long time. Paper extending from the non-elongation of the side sheet 70 to the maximum elongation The size of the transverse direction X of the diaper 1 is relatively large from about 550 to 1250 mm, and it can be suitably worn as a disposable diaper for a wide and wide-sized wearer. When the disposable diaper 1 is worn on the wearer, for example, the wearer is placed laterally on the bedding, and as shown in Fig. 2, the disposable diaper 1 is unfolded on the bedding, and the disposable diaper 1 is placed on the back while lying on the back. User's buttocks. Furthermore, the wearer turns over and lie on the opposite side, and after tidying up the disposable diaper 1, the wearer is placed on his back. Thus, when the wearer turns over, it is desirable to straighten the side sheet 70 so as not to bend or bend, and straightly extend in the lateral direction X. Since the side edges 16 of the disposable diaper 1 are extended by the side sheets 70, this tends to extend from the side of the wearer, and the pull-side sheets 70 easily align the position of the disposable diaper 1 with the wearer. When the disposable diaper 1 is placed on the wearer's buttocks, the front waist region 11 of the disposable diaper 1 is abutted against the wearer's abdomen, and the hook elements 95 formed on the side sheet 70 are caught outside the front waist region 11. Sheet 30.

Since the above-described disposable diaper 1 has the stretchable side sheet 70, it can be used by a wearer of various waist sizes. When compared to a baby, the wearer's waist size can span a wide range. When you are an adult, the size of the waist is also different for men and women, and because of the difference in personal physique. By using the stretchable side sheet 70, the range of application to the waist of the wearer can be widely set.

The side sheet body 70 continuously extends from the rear end edge 15 to the crotch region 13 in the rear waist region 12, and the dimension of the longitudinal direction Y is about 180 to 300 mm, and is about 240 mm in this embodiment. The dimension of the longitudinal direction Y of the back waist region 12 is about 260 to 320 mm, and in this embodiment, it is about 281.8 mm, and the dimension of the longitudinal direction Y of the front waist region 11 is about 170 to 240 mm, and in this embodiment, it is about 193.5 mm. Before and after The size of the longitudinal direction Y of the waist regions 11, 12 is the size from the front and rear end edges 14, 15 of the main body 10 to the boundary of the crotch region 13 which is smaller than the size of the lateral direction X. The side flaps 70 extend not only to the waist opening formed by the front and rear end edges 14, 15 but also to the side edges 16 of the underarm region 13 in the rear waist region 12 by extending to almost the entire longitudinal direction Y thereof. The formed diaper 1 is brought into close contact with the wearer in the vicinity of the formed leg opening. Furthermore, since the side sheet 70 is larger than the longitudinal direction Y of the front waist region 11, the entire sheet Y in the longitudinal direction Y of the front waist region 11 can be joined to the side sheet 70, and the front waist region 11 can be closely attached to the whole. Wear the user. In addition, "the side sheet 70 extends to almost the entire longitudinal direction Y of the back waist region 12" means that the effect of bringing the waist opening and the vicinity of the leg opening to the wearer can be exhibited, or The effect of the waist region 11 being closely attached to the wearer includes a smaller or larger size than the longitudinal direction Y of the rear waist region 12.

As described above, in the rear waist region 12, when the side sheet 70 extends almost in the entire longitudinal direction Y, it is less troublesome than the case where the size of the longitudinal direction Y of the side sheet 70 is small, and the connection to the front waist region 11 is also Difficult to change. However, according to this embodiment, since the plurality of hook elements 95 are separated in the longitudinal direction Y, the hook elements 95 can be connected to the front waist region 11 one by one, and even if the side sheet 70 becomes larger in the longitudinal direction Y, it is easy to connect this to Front waist area 11. Further, since the hook element 95 is fixed to the one piece of the first tongue piece 91, when the one of the hook elements 95 is pulled, the other hook element 95 also moves to some extent, so that it is difficult to disperse. After the hook element 95 of one of the hook elements 95 is connected to the front waist region 11, the other hook element 95 can be easily connected.

Although the leg elastic body 51 is attached to the crotch region 13 of the disposable diaper 1, the second end edge 51b is located inside the lateral direction X of the side sheet 70. In other words, the second end edge 51b of the leg elastic body 51 is interposed between the pair of side sheets 70, and the imaginary extension line and the leg elastic body which extend the front end edge 70a of the pair of side sheet bodies 70 in the lateral direction X. 51 cross. When the sheet body 70 is pulled outward in the lateral direction X and is coupled to the front waist region 11 by such a positional relationship, the second end edge 51b of the leg elastic body 51 is also pulled outward in the lateral direction X to be mounted.
