[0028] Referring to FIG. 3A, the left side shows a schematic cross-sectional view taken along TX in FIG. 2A. On the other hand, on the right side is a schematic cross section cut along the TDB, with the application means removed. 3B to 3D, which are schematic cross-sectional views taken along the TDB. The application means has been removed. The line TDB is connected to the inner cuff ( 68) is bonded to the topsheet (58) and is present where the elasticity is deactivated. 3A to 3D, the dimensions in the thickness direction are resolved. Referring to FIG. 3D, the absorbent article of the present invention is arranged laterally outward and includes a core chassis (6 A pair of water-impermeable cuff materials (102) are wrapped around a pair of side edges of the The leg gasket system (100) is Extending the cuff material (102) inwardly onto the wearer-facing side of the chassis (61) a pair of wearer-facing cuff regions (64) formed by The facing cuff region (64) includes a longitudinally extending inner cuff sealing (68S) and an inner a longitudinally extending inner cuff positioned inward from the cuff sealing (68S); The inner cuff sealing (68S) is made of a cuff material (102) and a free edge (68E). The inner cuff elastic element (69) is joined to the top sheet (58), and the inner cuff free edge (6 8E). By "adjacent" it is meant that the inner cuff elastic element (69) is positioned adjacent to the inner cuff itself. About 0.5 mm to about 3 mm away from the free edge (68E) or the inner cuff free edge (68E) This means that the inner cuff sealing (68S) is located approximately 1mm to 2mm away from the ) heat-bonds the cuff material (102) and the topsheet (58), for example, by adhesive. Securely bonded by adhesive, ultrasonic bonding, or any combination thereof Together, these are attachment means that provide leakage protection along the side edges of the absorbent body (38).

[0029] Referring to Figures 3A-3D, the leg gasket system (100) also includes a core shaft. By extending the cuff material (102) inwardly on the garment-facing side of the sleeve (61), A pair of garment-facing cuff regions (72) and a wearer-facing cuff region (73) are formed by 64) or a pair of outer cuff elastic elements ( ) disposed on the garment-facing cuff region (72) 70, 74), the outer cuff elastic elements overlapping the core side regions (62) and the inner cuff The outer cuff elastic element is disposed outward from the sealing (68S). Referring to FIG. 3D, (70) may be disposed on the cuff region (64) facing the wearer. 0) is placed on the cuff area (64) facing the wearer, the cuff area ( 72) may be devoid of any outer cuff elastic elements. Referring to Figures 3A-3C, An outer cuff elastic element (74) may be disposed on the garment-facing cuff region (72). When the elastic element (74) is disposed on the cuff region (72) facing the garment, it The cuff region (64) may be devoid of any outer cuff elastic elements.

[0030] Without being bound by theory, it is believed that the core chassis (61) is provided laterally outwardly. A pair of non-woven fabrics (61) enveloping the pair of side edges and extending inwardly toward the garment-facing side of the core chassis (61). By having a water permeable cuff material (102), the leg gasket system ( 100) provides improved tactile softness and coverage, and provides a high quality finish and appearance. Furthermore, the outer cuff elastic elements (70, 74) can be attached to the core side regions (6 2) By arranging the overlapping portions, the perceived and actual leakage protection performance is maintained. These and other advantages may be further achieved by adopting configurations that are described in more detail below. This can be achieved or enhanced.

[0031] Referring to Figures 3A-3D, a cuff is provided to form the cuff region (64) facing the wearer. The material (102) comprises a double layer inner cuff (68) with an inner cuff elastic element (69) sandwiched therebetween. The outwardly folded material may be formed at the inner cuff sealing (68S). Alternatively, the outwardly folded material is joined to the inner Cuff material (102) between the side cuff free edge (68E) and the inner cuff sealing (68S) The inner cuff elastic element (69) may be bonded to the inner cuff (68). In other embodiments, the inner cuff elastic elements (69) may span the longitudinal length of the crotch. The inner cuff (68) may extend over at least the longitudinal length of the inner cuff (68) in the lower region 30. The sexual element (69) is such that the inner cuff (68) remains in contact with the wearer during normal wear. It is desirable that the inner cuff (68) exhibits sufficient elasticity to enhance the barrier properties of the inner cuff (68). Preferably, the inner cuff free edge (68E) is located toward the edge of the absorbent body (38). The length of the cuff (68) as well as the length of the active elastic inner cuff elastic element (69) are controlled. To do so, it can be joined to the topsheet (58).

[0032] Referring to FIG. 2A, the line TDB is the distance between the inner cuff (68) and the topsheet (58). The inner cuff (68) is connected to the elastic portion of the inner cuff (68) and is located at the location where the elastic is deactivated. The bond may be provided towards both the front and rear edges of the absorbent body (38). Similarly, the cuff region (6) facing the wearer includes the outer cuff elastic elements (70, 74). 4) or the garment-facing cuff region (72) may be formed by a core chassis or application means, as described below. and may be joined to the front and / or rear edges of the absorbent body (38). The inner cuff elastic element (69) or the outer cuff elastic element (70, 7 4) in the area where the elasticity is deactivated, the cuff material (100); Adhesive is provided for bonding to the topsheet (58) or outer cover (42). The outer cuff elastic may or may not be provided on the garment-facing cuff area (72). Focusing on element (74), the adhesive is attached to the outer cuff elastic element with the deactivation area. Alternatively, the adhesive may be applied along the entire length of the substrate 74. In this case, the outer cuff elastic element (74) may not be provided. If adhesive is provided in the deactivation area, the cuff material (100) are firmly joined to each other and to the core chassis (61), thus Unexpected folding of the material during application can be avoided. If no protective layer is provided in the deactivation area, the edges of the absorbent body will be soft and flexible. can be maintained.

[0033] Referring to Figures 3C and 3D, the garment-facing side of the garment-facing cuff region (72) is formed The cuff material (102) for forming the cuff is defined with a fold facing the first garment. The cuff material (102) for forming the facing cuff region (72) is The side edges of the outer cover (42) may end at the innermost position of the back shell (72). The edge of the gate (60) may be located inwardly of the side edge of the gate (60). By providing a side edge with a gasket system, this allows for a flexible and breathable We provide a gasket system.

[0034] Referring to FIGS. 3A and 3B, a cuff material for forming a first garment-facing fold is The material (102) is further folded and extends outward to form a fold facing the second garment. The outer cuff elastic elements (74) may have a fold facing the first garment and a fold facing the second garment. The outer cuff elastic element (74) is a plurality of elastic strands. In this case, all of the outer cuff elastic strands (74) face the first garment, as in Figure 3B. It may be sandwiched between the fold and the fold facing the second garment, or at least one The outer cuff elastic strands (74) are folded in a first garment-facing fold as shown in FIG. 3A. The second garment may be sandwiched between the folded portion facing the second garment. The edge of the fold facing the back sheet (60) may be located inward from the edge of the back sheet (60). Providing the side edges of the leg gasket system with less material This provides a flexible and breathable leg gasket system. 3B, the edge of the fold facing the second garment is positioned on the side of the backsheet (60). The outer cuff elastic element (74) may extend beyond the edge and completely sandwich the outer cuff elastic element (74). , Lofty, side edges of the leg gasket system may be provided.

[0035] Each of the inner cuff elastic element (69) and the outer cuff elastic element (70, 74), respectively: It may be an elastic film, one or more elastic ribbons, or multiple elastic strands. When multiple elastic strands are arranged for the elastic element, the thickness is about 310 dtex to about 500 dtex. Those having a denier of 680 dtex may be arranged at an elongation rate of about 330% or less. By elongation, "0% elongation" means the original length of the elastic member. The tension and elongation may be suitable to provide the desired force while being less irritating to the wearer. The outer cuff elastic elements (70, 74) are one or more If equipped with upper elastic strands, total number of outer cuff elastic strands (70, 74) on one side may be at least 3. Such a plurality of outer cuff elastic strands (70, 74) The electrodes may be arranged at a pitch of less than about 8 mm, or less than about 6 mm. The outer cuff may have at least three outer cuff elastic strands (70, 74) on each side, but not all. This provides good leak protection with less stress on the wearer's skin. It is believed that this can be done.

[0036] If the outer elastic elements (70, 74) are provided with multiple elastic strands, the outermost The force provided by the outer cuff elastic strands (70, 74) present in the even if the force is lower than that provided by the outer cuff elastic strands (70, 74) present in For example, if there are three elastic strands, the outermost strand will It may be possible to provide a lower force than two elastic strands, e.g., four elastic strands. If there is a force, the two outer strands exert a lower force than the remaining two elastic strands. Without being bound by theory, it may be possible to provide a lower force to the outer strands. By providing this, stress on the wearer is reduced and the device is flexible while maintaining leak protection. It is believed that a soft fit is achieved.

[0037] Referring to FIG. 3B and FIGS. 3BE1-3BE3, forming a first garment-facing fold The cuff material (102) for the purpose of the cuff is further folded and extends outward to face the second garment. The outer cuff elastic elements (74) may form a fold facing the first garment. In such a configuration, the first garment-facing fold is sandwiched between the second garment-facing fold. The fold facing the first garment and the fold facing the second garment are secured with fold support glue. The outer cuff may be bonded by a fold support adhesive (FSG), and the fold support adhesive (FSG) may be bonded by an outer cuff elastic. Join the inward position from the inward-most edge of the element (74). In addition to the bond created by bonding the cuff material (102) to the cuff material (102), By providing a fold support adhesive (FSG) in a suitable location, the fold facing the second garment is The folding may be a process step after fabrication of the leg gasket system (100). The folding support adhesive (FSG) ) may also join the innermost locations of the outer cuff elastic elements (74). Referring to FIG. 3BP1, if the outer cuff elastic elements (74) are elastic strands, they may be folded. The Fold Support Adhesive (FSG) shall be applied to at least the most inwardly positioned outer cuff elastic. The strands (74) may be joined. Referring to Figures 3BE2 and 3BP2, the outer cuff elastic When the elastic element (74) is a plurality of elastic strands, the fold support adhesive (FSG) is The outer cuff elastic strands are positioned most inward and the second most inward.
