[0007] "Longitudinal" means substantially perpendicular to the article from one waist edge to the other waist edge of the article, and Refers to a direction extending generally parallel to the largest linear dimension of an item.

[0008] "Transverse" refers to a direction perpendicular to the longitudinal direction.

[0009] "Proximal" and "distal" refer to areas closer and farther, respectively, from the longitudinal center of the article. This refers to the desired location.

[0010] "Inward" and "outward" refer to positions closer to or closer to the lateral center of the article, respectively. points to a more distant location.

[0011] "Body-facing" and "garment-facing" refer to an element, or a surface of an element, or "Body-facing" refers to the relative position of an element or surface relative to some other element. "Garment-facing" means closer to the wearer during wear than the bare or surface. An element or surface that is moved farther away from the wearer during wear than any other element or surface. (i.e., the element or surface is attached to a wearer's garment that may be worn over a disposable absorbent article) proximal to

[0012] "Disposed" refers to an element being placed in a particular place or position.

[0013] "Joined" means that an element is attached directly to another element, such that the element is and a structure in which an element is attached to an intermediate member and the intermediate member is attached to the intermediate member. The material is then attached to other elements, so that the element is indirectly attached to the other elements. This refers to a configuration in which the material is attached to a surface.

[0014] "Film" refers to a sheet-like material in which the length and width of the material are significantly greater than the thickness of the material. Typically, the film has a thickness of about 0.5 mm or less.

[0015] "Water-permeable" and "water-impermeable" are used in the context of the intended use of a disposable absorbent article. Specifically, the term "water permeability" refers to the ability of a layer or layer structure to withstand pressure. A pore, opening or aperture that allows liquid water, urine, or synthetic urine to pass through the thickness of the layer or layer structure in the absence of pressure. In contrast, the term "impermeable" refers to a structure having a watertight opening and / or interconnected voids. "Self-stable" refers to the ability of a layer or layer structure to remain liquid in the absence of any compressive forces (other than those of gravity or other natural forces). This definition means that body water, urine, or synthetic urine cannot pass through the thickness of the layer or layer structure. The water-impermeable layer or layer structure may be permeable to water vapor, i.e., "vapor permeable". It may also be "transient."

It can stretch to an extended length of at least about 110% of its original length (i.e., It can stretch 10% longer than the original length, and when the applied force is removed, it completely bursts or breaks. This refers to materials that do not stretch and exhibit little recovery, less than about 20% of their stretched amount. If a material recovers at least 40% of its elongation when an applied force is released, the material is considered to be A stretchable material is considered to be "elastic" or "elastomeric". For example, An elastic material with an initial length of 1.5 mm can be stretched to at least 150 mm and can be subjected to a force When removed, it shrinks to a length of at least 130 mm (i.e., a 40% recovery). A material is considered to be non-extensible if, upon release of the applied force, it recovers less than 40% of its elongation. A material is considered to be "substantially non-elastic" or "substantially non-elastomeric." For example, an extensible material having an initial length of 100 mm will stretch to at least 150 mm. When the force is removed, it shrinks to a length of at least 145 mm (i.e., 10% (indicating recovery).

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). The outwardly folded material is then joined to the top sheet (58). Alternatively, the outwardly folded material is joined to the inwardly folded material. Between the side cuff free edge (68E) and the inner cuff sealing (68S) is a cuff material (102) 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 adapted so that the inner cuff (68) remains in contact with the wearer during normal wear. It is desirable for the inner cuff (68) to exhibit sufficient elasticity to enhance the barrier properties of the inner cuff (68). Preferably, toward the edge of the absorbent body (38), the inner cuff free edge (68E) is The length of the cuff (68) as well as the length of the active elastic inner cuff elastic element (69) are controlled. To achieve this, the fabric may 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). Such a portion of the inner cuff (68) is bonded to the inner cuff and the elastic is deactivated. The bonds may be provided toward both the front and back 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 from a core chassis or application means, as described below. , and may be elastically bonded toward the front and / or rear edges of the absorbent body (38).

An outer cuff elastic is 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 the embodiment, 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 non-activated area, the edges of the absorbent body will be soft and flexible. It can be maintained.

[0033] 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 terminate at the innermost position of the backshell (72). The edge of the hole (60) may be located inwardly of the side edge of the hole (60). By providing side edges with a gasket system, this allows for a flexible and breathable liner. 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 outwardly to form a fold facing the second garment. The outer cuff elastic elements (74) may be folded over facing the first garment and folded over 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 FIG. 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 and the folded portion facing the second garment. The edge of the fold facing the seat 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 that faces the second garment is on the side of the backsheet (60). It 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 elastic strands may be about 310 dtex to about 310 dtex. The fabric may have a denier of 680 dtex and be arranged at an elongation rate of about 330% or less. By elongation, "0% elongation" means the original length of the elastic member. The knit and elongation rates can 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 studs may be arranged at a pitch of less than about 8 mm, or less than about 6 mm. The cuff may have at least three outer cuff elastic strands (70, 74) on each side, but not all. This provides better leak protection with less stress on the wearer's skin. It is believed that this can be done.

[0036] When 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 at a force 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 be It may be possible to provide a lower force than two elastic strands. For example, 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 smaller force to the outer strands. By providing this, stress on the wearer is reduced and the device is flexible while still maintaining leak protection. It is believed that a soft fit is achieved.

[0037] Referring to FIG. 3B and FIGS. 3BE1-3BE3, a first garment-facing fold is formed. The cuff material (102) for providing the cuff is further folded and extends outwardly to face the second garment. The outer cuff elastic elements (74) may form a fold that faces the first garment. In such a configuration, the first garment facing fold is sandwiched between the second garment facing fold.
