A DETAILED description of the PREFERRED OPTIONS of the INCARNATION

The present invention is directed to an absorbent item of clothing type shorts, containing curved cuffs for legs. Curved cuffs for the legs, in accordance with the present invention, represent elastic elements for legs having a protruding elastic sections along the length cuffs for the legs, and the United elastic sections along the length cuffs for legs. Protruding sections and the United plots were part of a single unit of an elastic element. The connected site is a part of the cuff to the leg, which is connected with the substrate. Unattached plot can last from United parcel at an angle or may be imposed on the linked site by folds along the length of the cuff to his feet. Unattached the plot has more freedom to respond to nutrena voltage, when the clothing item is in a weakened state than the linked site due to the fact that the linked site is connected to the substrate in the stretched condition, so that movement of the linked site may be limited by the substrate. Disproportionate freedom of movement along the length of the cuff to the feet creates a bending cuffs for legs. In addition to the bending generated a disproportionate freedom of movement, coupled plot is connected with the substrate at the periphery of the curved cutout in the substrate. The curved shape United parcel increases the bending cuffs for legs.

The principles of the present invention can be used in any suitable disposable absorbent product. Examples of such suitable articles include diapers, training pants, products for women's hygiene products for patients suffering from incontinence, other items of personal hygiene or items of clothing for the sick and the like. Used herein, the term "product for patients suffering from incontinence" includes absorbent underwear for children, absorbent items of clothing for children or adolescents with special needs, such as children with autism or other problems of control of bladder/bowel due to physical defects, as well as absorbent articles of clothing for the elderly l is dei, suffering from incontinence.

For ease of explanation the following description will be made regarding training pants for children.

Figure 1 is a disposable absorbent product, such as training pants 20, shown in a sealed condition. Cuff 10 feet are used around holes 12 for leg training pants 20 to reduce or prevent leakage. The main part 14 forms an opening 12 for the legs and a hole 13 for the waist. When the cuff 10 foot made curved, as in the present invention, the cuff 10 foot provide the best fit to the form than the elastic elements for legs with straight edges. The term "elastic elements for legs with straight edges" refers to the usual elements for legs without acting out the parts that are fully connected along the entire length with a straight edge of the substrate. In addition, curved cuff 10 feet, in accordance with the present invention, creating a seal. The term "seal" refers to the tool that is used to block leakage of fluid around the leg holes between the garment and the user's legs. In the opening 12 foot going with a small tension, because the holes 12 foot should not overcome the efforts from the side of the base part 14, which must overcome the elastic ele the coefficients for feet with straight edges. Low tension and adjustment of the form allow you to obtain the absorbent article 20 with improved comfort. In addition, curved cuff 10 foot have finished seam 16 at the connection point to the main part 14, which allows to provide an aesthetically pleasing appearance.

The substrate 40, as shown in figure 2, is usually a lining 42 or the outer coating 44 absorbent element 20 service (figure 1). As shown in figure 2, the substrate 40 preferably has a curved cut along at least one edge 46. The term "bent neck" refers to any neckline with curved edge, which may include one material cut so as to form the neckline, or a few materials, which are connected together to form a cut shape. Connected region 54 in which the cuff 10 for legs are connected to the substrate, approximately parallel to the curved shape of the cutout area for the feet. Parallel line connected region 54 passes towards the center of the product, providing a connected region 54 with a large radius in comparison with the hole for the legs. Larger radius leads to the fact that the cuff 10 for legs going to the center of the holes for the legs when used as cowards, while allowing for the shrinkage of the cuff 10 for legs, so she's in the product adopts the most free state. Before those who like the cuff 10 for legs will be connected to the substrate 40, curved cut line with a connected region 54 on the cuff 10 to the legs, as shown in figure 2. In the first section 38 of the cuff 10 for legs connected to the substrate 40 along the edge of the adjacent curved neckline. The substrate 40 is preferably stretchable, thus providing great flexibility and allowing you to apply the cuff 10 to the legs while her weak tension.

In the first sections 38 of each of the cuffs 10 feet connect with the substrate 40 along the edge adjacent each of the curved cut. The second section 39 of each of the sleeves 10 for the leg acts up from the substrate 40 and serves as a seal during subsequent use of the object 20 service, as explained below. The substrate 40 may have a continuous length, and in this case, the substrate 40 is cut into separate parts for each subject 20 service followed by the process connection.

Figure 3 shows a front view of the absorbent element 20 of the garment with a pair of curved cuff 10 for legs connected to the substrate 40, in this case with the outer coating 44. Each of the curved cuff 10 for legs can be connected to the substrate 40, or in the course of performing successive operations, or both.

Figure 4 shows a front view of the absorbent item 20 service, showing curved cuff 10 for legs with wrapped edges 58, forming a J-obraz the th form. Rolled edges 58 provide greater strength and reinforcement around openings 12 for the legs in addition to a more finished appearance. Figure 5, 6 and 7 also shows the rolled edges 58. Rolled edges 58 contain double the amount of elastic material and, thus, provide double the voltage and double sealing force compared to nezagorelymi edges. An additional strip of elastic material 60 may be located in the bend wrapped edges 58, as shown in figures 5, 6 and 7, to create even greater effect Assembly of the cuff 10 feet, with a smaller circle for more elastic seal. An additional strip of elastic material 60 is preferably made on the basis of elastic material, which is also activated with heat, as described in U.S. patent No. 4816094, issued March 28, 1989, the authors Pomplun and others, which is included here by reference. Wrapped edge 58 may be connected using any suitable means, including adhesive connection, ultrasonic connection, thermal connection or mechanical connection. The resulting seam 16, shown in Fig.7, connecting the cuff 10 and the substrate 40 has a finished appearance, because the edges of the substrate 40 and the first section of the cuff 10 feet hidden in the front on one side of the seam 16.

The first is castke 38 of the cuff 10 for legs can be connected to the substrate 40 by ultrasonic connection, as described above, or by various other techniques, including adhesive connection, thermal connection, the connection seam or other traditional technologies. Suitable adhesives include spray adhesives, adhesives, hot melt, samokleyashchiesya elastomeric materials, etc.

As soon as the cuff 10 foot connected with the substrate 40, the edges 50 and 51 can be connected with edges 52 and 53, respectively, as shown in figure 2, for the formation of the element 20 of the garment shown in figure 1. After formation of the element 20 of the second service areas 39 cuffs 10 feet protrude from the surface of the item of clothing. When using the second sections 39 cuffs 10 foot firmly pressed to the skin of the user and serve as a seal to reduce or prevent leakage through the holes of the element 20 service.

On Fig absorbing element 20 of the garment of figure 1 shown in a partially disassembled stretched flat state, so that shows the surface that faces the user's body while wearing the item of clothing. In addition to the formation of holes 12 and the holes 13 for the waist (figure 1) absorbing the main part 14 forms a pair of transversely opposite side edges 136 and a pair of longitudinally opposite waist edges, which are designated as the front edge 138 of the waist and the rear edge 139 of the waist. The basis of the Naya part 14 also includes, in General, a rectangular composite structure 133, a pair of transversely opposite front side panels 134, and a pair of transversely opposite rear side panels 234. Composite structure 133 and the side panels 134 and 234 can be formed in one piece, as shown in figure 2, or may include two or more separate elements, as shown in figures 1 and 8.

Shown in the drawing composite structure 133 includes the outer coating 44, the pad 42 on the side of the body, which is connected with an outer coating when applying it, and absorbent structure 144, which is located between the outer surface 44 and lining 42 from the side of the body. Rectangular composite structure 133 includes opposite linear end edges 145, which form parts of the front and rear edges 138 and 139 of the waist, and opposite linear or curved side edges 147, which form parts of the side edges 136 absorbing base part 14. Holes 12 foot (figure 1) is usually formed by sections of the transversely opposite side edges 136. For reference, arrows 48 and 49, showing the orientation of the longitudinal axis and transverse axis, respectively, the training pants 20, shown in Fig.

Permeable to fluid lining 42 from the side of the body is shown overlaid on the outer coating 44 and the absorbent structure 144 (Fig) and may,but not necessarily have the same dimensions, as the outer coating 44. Lining 42 from the side of the body is preferably pliable and soft to the touch and does not irritate the baby's skin. In addition, the lining 42 from the side of the body may be less hydrophilic than the absorbent structure 144 to provide for the user a relatively dry surface and so that the fluid can freely penetrate through its thickness.

Absorbent structure 144 (Fig) is located between the outer surface 44 and lining 42 from the side of the body, and these components can be connected together using any suitable means, such as adhesives, as is well known in this field. Absorbent structure 144 can be any structure which, in General, is compressible, comfortable, does not irritate the baby's skin, and allows you to absorb and retain liquids and some bodily fluids. Absorbent structure 144 may be fabricated using a wide variety of sizes and shapes and with the use of a wide variety of materials, absorbent, usually used in this field. For example, the absorbent structure 144, respectively, may include a matrix of gidrofilnyh fibers, such as a sheet of cellulosic fluff, mixed with particles of a material with high absorption capacity, which is usually from the local as ultra-absorbent material. In a particular variant embodiment of the absorbent structure 144 includes a matrix of cellulosic fluff, such as fluff wood pulp and forming ultra-absorbent hydrogel particles. Fluff wood pulp can be replaced by a synthetic polymer fibers blown from the melt, or by a combination of exhaust from the melt fibers and natural fibers. Ultra-absorbent particles can essentially be evenly mixed with hydrophilinae fibers or can be mixed evenly. Pooh and ultra-absorbent particles can also be selectively placed in preferred areas of the absorbent structure 144 for best contents and absorption of secretions of the body. The concentration of ultra-absorbent particles may also vary according to the thickness of the absorbent structure 144. Alternatively, the absorbent Assembly 144 may include a laminate of fibrous cloths and ultra-absorbent material or other suitable means of retaining ultra-absorbent material in a localized area. Another type of absorbent material suitable for absorbing structures 144, is a together form a material that is a mixture of fibers of staple length fibers blown from the melt, as described in U.S. patent 4100324 included here by reference. The weight ratio of fiber stapel the Noah length fibers, removed from the melt, may be in the range between 30 (fiber staple length)/70 (fibers blown from the melt) and 90 (fiber staple length)/10 (fiber, blown from the melt). Fibers from wood pulp are the preferred staple fibers, and polypropylene is preferred for the fibers blown from the melt. Ultra-absorbent materials can be added together to form the materials to increase the capacity.

Suitable ultra-absorbent materials can be selected from natural, synthetic and modified natural polymers and materials. Ultra-absorbent materials can be inorganic materials such as silica gels, or organic compounds, such as polymers with cross links. Suitable ultra-absorbent materials are available from a variety of commercial companies, such as Dow Chemical Company located in Midland, Michigan, USA, and the company Stockhausen GmbH & Co., KG, D-47805 gcrald, Federal Republic of Germany. Typically, ultra-absorbent material can absorb at least about 15 times more water than its own weight, and preferably makes it possible to absorb more than about 25 times more water than its own weight.

In one variation of the embodiment of the absorbent structure 144 has the essentially rectangular in shape and includes a mixture of fluff wood pulp and ultra-absorbent material. One preferred type of fluff is identified as trade designation CR1654, which is supplied by the company's U.S. Alliance, the city of Childersburg, Alabama, USA, and is a bleached sulphate wood pulp with high absorbent, containing primarily soft wood fibers. Usually ultra-absorbent material present in the absorbent structure 144 in an amount of from about 0 to about 90 wt. percent based on the total weight of the absorbent structure. Absorbent structure 144 preferably has a density in the range of from about 0.10 to about 0.35 grams per cubic centimeter. Absorbent structure 144 may or may not be wrapped or surrounded by the respective fabric wrap that maintains the integrity and/or shape of the absorbent structure.

Absorbing the main part 14 may also include other materials, which are made primarily for the reception and temporary retention and/or transfer of liquid along the mutually facing surface of the absorbent Assembly 144, thereby increasing the absorbent capacity of the absorbent structure. One suitable material is indicated as an exciting layer (not shown) and contains a material having a basis weight of about 50 grams per square meter and includes the painting of carding, United through the your weave in the air stream, of a homogeneous mixture consisting of 60 percent bicomponent fibers of a thickness of 3 denier containing a polyester core/polyethylene sheath, supplied by BASF Corporation, and 40-percent polyester fiber thickness of 6 denier, which is supplied by the company Hoechst Celanese Corporation, Portsmouth, Virginia, USA.

Many elastic materials can be used for cuffs for 10 feet. As is well known to specialists in this area, suitable elastic materials include sheets, strands or strips of natural rubber, synthetic rubber, or thermoplastic elastomeric polymers such as extruded polyurethane film. Specific type of suitable elastic material is coupled with stretching the laminate (SBL), which is described in more detail below, with reference to the elastic side panels.

Elastic materials can be stretched and connected by adgezirovannah with the substrate, can be connected through adgezirovannah collected with the substrate or may be connected with the substrate and then they can be given properties of elasticity, or they may be subject to shrinkage, for example, under the application of heat; so that the elastic force of compression was applied to the substrate. One way stretch elastic material and putting them through hell is tiravanija on a substrate is described in U.S. patent No. 4883549, issued 28 November 1989 (Frost and others), which is incorporated by reference. Heat shrinkable elastic material is described in U.S. patent No. 4,640,726, issued February 3, 1987 (Sallee and others), which is included here by reference. In one particular variant embodiment of the cuff 10 foot include, for example, the set formed by the dry process fused multi-fiber elastic filaments of material "spandex", known under the trade name LYCRA®supplied by E.I.DuPont de Nemours and Company, gailingen, Delaware, USA, adhesive laminated between layers of nonwoven material.

Each of the cuffs 10 foot preferably has a width of about 0.5 inch (1 cm) to about 5 inches (13 cm), more preferably about 1 inch (2.5 cm) to about 4 inches (10 cm) and most preferably from about 1.5 inches (4 cm) to about 2.5 inches (6 cm). The second sections 39 cuffs 10 feet preferably have a width of from about 0.25 inches (0.6 cm) to about 4 inches (10 cm), more preferably from about 0.5 inch (1 cm) to about 3 inches (7.5 cm), most preferably from about 1 inch (2.5 cm) to about 2 inches (5 cm). The length of the cuff 10 for legs after they are cut with a cutting device 34 should essentially cover the circumference of the opening 12 for the legs. In addition, each of the cuffs 10 foot preferably has an elongation 25-350%, more preferably is about 30-260% and most preferably about 35-200%.

When the cuff 10 foot connected with the outer cover 40, the width of the joined area 54 is from about 1 mm to about 25 mm, preferably from about 3 mm to about 12 mm, more preferably from about 4 mm to about 8 mm, Connection can be done either with the use of the compounds in the form of a line, separate United parcel compounds in the form of multiple lines, multiple series connected sections of links, or a continuous pattern of connections, such as is formed by spiral spray adhesive or spray when the blast from the melt. Connection with a continuous pattern can include multiple continuous patterns obtained with the use of multiple spray holes. Connection in the form of lines have a width in the above-mentioned width of the joints and cover the full length of the curved cuff 10 for legs. Separate connected sites aligned in a row along the length of the curved cuff 10 feet, and each connection has a width in the above-mentioned width of the compounds. Separate connected sites are appropriate, because they have little resistance elastic band at the Assembly of the elastic band at the time of connection by adhesion with an outer coating compared with the compounds in the form of lines. Connection in the form of a variety of lines including the t several lines extrudable adhesive, which pass through the entire length of the curved cuff 10 for legs. A variety of individual United parcel include a variety of connected sites, which can either be shifted from each other, or parallel to, and cover the whole length of the curved cuff 10 for legs. The connection preferably is a superficial connection or with an external coating or lining on the part of the body. Surface connections simplify the process of attaching cuffs for 10 feet. In addition, the compounds according to the invention are hidden from view, because the cuff 10 for legs automatically wrapped over the connection. The compounds preferably are water-resistant in order to prevent leakage around the leg holes.

Connected region 54, appropriately located so that it is offset from the center of the cuff 10 to the foot, between the first section 38 and second section 39, essentially dividing the cuff 10 feet between the first section 38 and second section 39, as shown in figure 2. Excluding connected region 54 of the cuff 10 for legs, the first section 38 contains from about 0% to about 50% of the material of the cuff 10 for legs, and a second section 39 includes from about 50% to about 100% of the material of the cuff 10 for legs. For example, the first portion 38 may include about 25% of the material of the cuff 10 for legs, and a second section 39 may include the step about 75% of the material of the cuff 10 for legs, excluding connected region 54. The location connected region 54 is important because as the first section 38 and second section 39 work together to overcome the resistance of the material of the basic details of external coatings and linings on the part of the body, for Assembly holes for the legs to ensure a seal.

The design according to the invention imposes stringent requirements on the strength of the connection of the cuff 10-feet with a surface coating, since the voltage applied to the connection, is a voltage at breaking in contrast to the shear strain. Shear deformation is a typical voltage between the elastic material and an outer coating, which ensures that the resilient material will not slip out of the desired position due to the tension applied to the connection of elastic material, or by the user.

When using heat-activated latent elastic material attached in a flat form, the cuff 10 to the foot is essentially flat on the canvas, as shown in figure 5, before the application of the activation process of the cuff 10 for legs. Figure 6 shows the heat-activated cuff for 10 feet before activating when applying using the applicator at an angle of 90 degrees. 7 shows Angela 10 feet in working condition or after activation with heat. Cuff 10 to the legs are going along the path of least resistance, seeking to form the smallest possible circle. At the same time as the first section 38 and second section 39 going towards the center of the hole for the legs. Connected region 54 is limited to the main part and the main part prevents the formation of smaller diameter elastic region 54. Compared to non-hidden elastic material of the cuff 10 for legs with hidden elastic material allows much easier to align the edges 50 and 51 with the edges 52 and 53, respectively, as shown in figure 2.

The substrate 40 is preferably an outer covering 44 and preferably includes a material which, essentially, is impermeable to liquid and can be elastic, stretchable or extensible. The outer coating 44 may be a single layer impermeable to liquid material, but preferably includes a multilayer structure in which at least one of the layers is impervious to liquid. For example, the outer coating 44 may include permeable to liquid outer layer and impermeable to the fluids of the inner layer that are suitably joined together with an adhesive La laminated material (not shown). Suitable adhesives for laminated materials, to the which can be applied continuously or intermittently, in the form of drops, a sputtering method, a parallel spirals or similar patterns, supplied by Findley Adhesives, Inc., the city of Wauwatosa, Wisconsin, USA, or by the company National Starch and Chemical Company, the city of Bridgewater, new Jersey, USA. Permeable to liquid outer layer may be made of any suitable material and preferably of a material which provides, in General, a structure that is similar to the fabric. One example of such material is a non-woven fabric of melt of polypropylene with a weight per unit area of 20 g/m2(grams per square meter). The outer layer may also be made of such a material permeable to the liquid lining 42 from the side of the body. Although it is not necessary that the outer layer was permeable to liquid, preferably so that it formed a structure relatively similar to the fabric for a user.

The inner layer of the outer cover 44 can be simultaneously impermeable to liquid and vapor, or may be impermeable to liquids and permeable to vapor. The inner layer is preferably made of a thin plastic film, although they may also use other flexible impermeable to liquid materials. The inner layer or impermeable to liquid outer coating 44, when it is ipodnano of a single layer, prevents wetting by secretions of the body, such items as linens and clothing, as well as user and human caregivers. Suitable impermeable to fluid film for use as impervious to the fluids of the inner layer or single-layer impermeable to liquid coating 44 is a polyethylene film with a thickness of 0.02 mm, commercially supplied by Huntsman Packaging, Newport news, Virginia, USA. If the outer coating 44 is made of a single layer of material, it can be made by stamping and/or its surface may be made opaque to obtain the appearance, similar to the fabric. As stated above, impervious to the liquid material may allow fumes to exit disposable absorbent products, preventing the passage of fluids through the outer coating 44. Suitable "breathable" material consists of a microporous polymer film or a nonwoven fabric coated or treated to give it the desired level of liquid-proof. A suitable microporous film is a film material PMP-1, supplied by Mitsui Toatsu Chemicals, Inc., Tokyo, Japan, or polyolefin film XKO-S044, supplied by 3M Company, Minnea the OLIS, minn.

Lining 42 from the side of the body can be made of many materials in the form of a cloth, such as synthetic fibers (e.g. polyester or polypropylene fibers), natural fibers (e.g. wood or cotton fibers), a combination of natural and synthetic fibers, porous foam, foam with holes, plastic film with holes or similar materials. As the pads 42 on the part of the body you can use various woven and nonwoven fabrics. For example, the lining side of the body may consist of a fabric of polyolefin fibers blown from the melt or received spunbond method of producing the ejection of high-speed air flow. The lining on the part of the body can also be a canvas of wool spinning, consisting of natural and/or synthetic fibers. The lining on the part of the body may consist essentially of a hydrophobic material, the hydrophobic material may be treated with surface-active agent or may be subjected to other processing, to impart a desired level of wettability and hydrophilicity. For example, the material may undergo surface treatment with the use of about 0.28 wt. percent surfactant, delivering the constituent company Rohm and Haas Co. under the trade designation Triton X-102. Surfactant can be applied using any conventional method, such as spraying, printing, brush application or similar. Surfactant may be applied to the entire lining 42 from the side of the body or may be applied selectively to specific parts of the lining side of the body, such as the middle portion along the longitudinal Central line.

Suitable permeable to fluid lining 42 from the side of the body is a two-component non-woven fabric having a weight per unit area of about 27 g/m2. Non-woven two-component painting can be a two-part cloth obtained spunbond method of production or a two-part cloth of wool spinning. Suitable bicomponent staple fibers include polyethylene/polypropylene bicomponent fiber, supplied by CHISSO Corpotation, Osaka, Japan. In this particular example, two-component fiber polypropylene polypropylene forms the core and the polyethylene forms the sheath of the fiber. There might also be other fiber orientations, such as mnogogolovye, arranged next to each other, the United end to end, or similar. Although the outer coating 44 and liner 42 from the side of the body may include an elastomeric what materials, in some embodiments, the embodiment may be preferable that the composite structure was performed, in General, inelastic, while the outer coating, lining side of the body and the absorbent structure includes a material that, in General, are not elastomeric.
