RELATED APPLICATION [0001] This application claims the priority of US Patent Application No. 13 / 832,965 filed on March 15, 2013 and called "ABSORBENT ITEMS AND METHODS OF MANUFACTURING THEMSELVES" which is a partly related continuation with U.S. Patent Application No. 13 / 276,843 filed on October 19, 2010 and called “ABSORBENT ITEMS AND METHODS OF MANUFACTURING THEMSELVES” which claims the priority of US Patent Application No. 61 / 394,758 filed on October 19, 2011 and named "ABSORBENT ARTICLES AND MANUFACTURING METHODS OF THE SAME". This application also claims the priority of the Patent Cooperation Treaty Application (PCT) No. PCTUS1156869 filed on October 19, 2011. The content of each of these applications is incorporated herein by reference in its entirety.

BACKGROUND [0002] This invention relates generally to absorbent articles and, in particular, to absorbent articles with better fit, comfort and production feasibility.

[0003] Millions of people of all ages suffer from bowel or bladder incontinence. Whether a minor, adult or elderly, the underlying cause of incontinence varies, but the method of treatment usually involves products of absorbent articles. Disposable diapers, protective and incontinence briefs for adults can alleviate the physical and emotional discomfort of incontinence by absorbing and containing fluid and other secretions from the human body to prevent the body and clothing from getting dirty.

[0004] Despite the recent pressure from the Senior Health Insurance Centers and People's Health Insurance Services (CMS) to change clinical practice to promote the systematic treatment of incontinence, Continued misuse of incontinence absorbent products when treating urinary and fecal incontinence. The high prevalence of incontinence in nursing home residents results in Incontinence Associated Dermatitis (ICD) in the perineal region and is a common complication. Improper adjustment or use, providing the wrong size to a user of absorbent articles is a contributing factor to perineal dermatitis by producing a cumulative increase in heat or rubbing against the skin's superficial tissue.

[0005] In an attempt to improve performance and reduce abrasion on the skin, the absorbent articles industry has been introducing new product concepts with, for example, backsheets without being interwoven for comfort. However, these products still contribute to the development of ICD due to the wrong size and design on the crotch and the leg cut. In an attempt to provide the right size to the garments, a majority of current absorbent items are sold in five sizes: Medium, Regular, Large, Extra Large and 2X Large. However, these sizes do not solve the aforementioned aspects since the items do not fit sufficiently to users with different proportions of body size. As a result, caregivers constantly need to wear larger clothes, too large because the product design does not allow a good fit around the waist and thigh of the patients at the same time. Thus, caregivers are putting larger garments on patients to compensate for what leads to a higher cost; potential spills; and less dignity due to the use of a more voluminous garment.

[0006] In addition, not wearing the right size clothing on a patient suffering from incontinence violates federal government CMS-F315 rules that require health professionals and staff to use the correct size and type of clothing based to the condition and size of the patient.

[0007] In addition, multiple sizes are created by components of multiple sizes which leads to inefficient manufacturing processes. Each size requires the manufacturer to stop the machine and change a number of the machine sections to produce the following size. After changing the machine sections, other sections must be recalibrated to ensure that the raw material components are converted correctly . These changes may take 6 to 12 hours depending on the machine the manufacturer is using. This downtime reduces the amount of product that the machine can produce and increases the conversion costs of the manufacturers. In addition, current machines that produce adult panties are required to use extra steel and other materials to make additional components for additional sizes.

[0008] In another attempt to improve performance and fit, incontinence articles are configured with elastic material fastened on the back panel of the article's ears. However, elasticized briefs have shorter front panels to compensate for the cost of the elastic material. First, this requires the caregiver to use a different application technique because the fixing area is smaller. Secondly, when the elastic material is fully extended to fit the waist in patients who are at the upper limit of size, it can cause skin irritation and decomposition, particularly in the region of the waist and hip. The waist support parts are too stretched and poorly adjusted, deeply affecting the skin with which it is in contact.

[0009] In an attempt to improve the performance of an absorbent layer of the incontinence article, the upper part of a core of the absorbent layer can be enhanced. By enhancing the upper part of the absorbent layer the lateral movement of liquid that comes into contact with the absorbent layer can be increased and can reduce spills, but it can also increase the circular movement of the liquid and increase the spillage. Similarly, the layers Absorbents that have two cores have similar advantages and disadvantages. In addition, the flow between the upper core and the lower core may be insufficient, even when the upper portion of the lower core is enhanced.

[0010] In addition, when putting on the product, the side panels may be subject to significant forces, especially while the product is being used and the user's body weight is directly on the support structure of the absorbent article. These forces can be located along an edge of the article and therefore can cause a fala, for example, a tear in the panel, which spreads rapidly and completely across the length of the panel, causing a complete failure of the Article.

[0011] In addition, a patient with skin disorders in the hip region may benefit from a product that can provide softness and a more comfortable side panel. In addition, as adult products have evolved, these products now include side panels that are used for adjustment. Due to the way that these side panels are used, it is possible for the user to use the product in such a way that the side panel can come together and make the pressure lines against the one who uses them.In addition, when the product is manufactured product, the process of applying the side panel to the diaper includes a manufacturing step of folding a part of the side panel. If the elements of the manufacturing process are not ideal, waste can be created in the manufacturing process.

[0012] Accordingly, there is a need for absorbent articles to provide better fit and comfort, and increase absorption, while reducing the number of sizes within a range of products, manufacturing costs are reduced and as well as the impact on the environment. There is also a need for absorbent articles to resist accumulation, while at the same time providing softness and filling effect for the user. There is an additional need to improve the ability to bend this side panel during the manufacturing process.

The front panels are designed to be able to put a layer under the rear panels providing a more comfortable fit and reduces the trauma and degradation of the skin of the person using it.

[0050] Figure 1 shows in a plan view, an exemplary general non-limiting embodiment of an absorbent article 100 in a substantially flat state that does not contract (the first configuration), with a reduced component design that adapts to multiple user sizes. In this embodiment the article consists of a chassis 102, clamping portions 104, 106, 108, 110, a first core portion 116, and a second core portion 118. Although not shown in this figure, absorbent article 100 may include a set of spill protectors and / or a set of leg hems 142, 144, both known to those with experience in the medium. In this embodiment there are four body holding portions that include a first holding portion 104, a second holding portion 106, a third holding portion 108 and a fourth holding portion 110. It should be noted that the four clamping portions are used in this embodiment, however it should be recognized that other embodiments may be designed with more or less clamping portions.

[0051] The absorbent article 100 generally consists of several layers (see, for example, Figure 10), including an inner layer, an absorbent layer and an outer layer. The inner layer faces the user and comes into contact with the skin thereof when the absorbent article 100 is secured to the user. The inner layer can be composed of a moisture-permeable fabric suitable to allow body secretion to pass through the inner layer and be absorbed by the absorbent layer. Non-limiting examples of materials suitable for forming the inner layer include polypropylene, polyethylene, polyester, materials with hydrophobic properties, combinations thereof and / or the like. In addition, the inner layer can be treated with a hydrophilic finish to improve the passage of liquids to the layers of the diaper under the inner layer. Non-limiting examples of suitable hydrophilic finishes include stearic acid, melanin-based chemicals, fluorocarbon chemicals and silica-based chemicals.

[0052] The absorbent article 100 generally has a rear region 150 and a front region 160. The first holding portion 104 and the second holding portion 106 are coupled to and can extend from the rear region 150, and the third holding portion 108 and the fourth holding portion 110 are coupled to and can extend from the front region 160. The rear region 150 is generally placed against the back of the user. The frontal region 160 is generally placed against the front part of the user. The third holding portion 108 and the fourth holding portion 110 are designed to wrap around the user's waist from front to back and the first holding portion 104 and the second holding portion 106 are designed to wrap around the waist of the user from back to front. Thus, the first holding portion 104 and the second holding portion 106 can be coupled with the third holding portion 108 and with the fourth holding portion 110, respectively, to couple the front region 160 with the rear region 150.

[0053] The absorbent article 100 in this illustration of Figure 1 is shown with the portion of the absorbent article 100 that makes contact with the user shown facing the viewer. The absorbent article 100 includes a longitudinal axis 101 and a transverse axis 103. The absorbent article 100 includes a first end portion 105, a second end portion 107 and an intermediate portion 109. The first end portion 105 is also referred to herein as a front waist region 105, the second end portion 107 is also referred to herein as a rear waist region 107, and is substantially opposite to the first end portion 105 and the portion Intermediate 109 is also referred to herein as a region of the crotch 109 and is arranged longitudinally between the front and rear regions of the waist 105 and 107. The front region of the waist 105 and the rear region of the waist 107 generally comprise the portions of the absorbent article 100 which, when used, surrounds the wearer's waist. The crotch region 109 is that portion of the absorbent article 100 which, when the absorbent article is used, is generally placed between the user's legs. The rear clamping portions 10 and 106 and the front clamping portions 108 and

110, are separated by the distance L1 114. The distance L1 114 defines a portion of the leg opening.

[0054] The chassis of article 102 has a chassis width CW 112 and a chassis length CL 111. Chassis width 112 is a common width 15 in all sizes of the article, which conforms to a plurality of sizes of Body. In other words, the absorbent article 100 has a multi-adjustable width 112 and a multi-adjustable length 111. Even so, put in other words, a chassis width 112 is used for different article sizes while still adjusting to different body sizes of the 20 users. For example, there are two chassis lengths, as shown in the

Figures 2 and 3 in combination with Figure 1, a first chassis length CL 211a, 211b for a first article size and a second article size, in this embodiment a Medium size and a Regular size, and a second chassis length CL 311a, 311b for a third size of the article and a fourth size of the 25 article, for example a large size and an extra large size in this embodiment.

[0055] The chassis 102 has a shape such that its outer perimeter is rectangular or at least substantially rectangular in the first configuration. In this embodiment the absorbent article 100 has at least one fastening portion that engages the chassis 102 in a front region of the waist 105 or in the rear region of the waist 107. In other embodiments, there may be portions of the chassis that are shaped and / or removed, such as in the crotch region 109, for example, resulting in a portion of the narrower crotch region 109 to provide a contoured fit between the legs. Still other embodiments have chassis in different shapes, such as hourglass, T-shape and the like.

[0056] The first clamping portion 104 is coupled to a first longitudinal side edge portion 113 of the chassis, the first clamping portion 104 superimposed on the chassis 102 along the linear contact points of the attachment 132. The amount of Overlapping is sufficient to reliably connect the clamping portion to the chassis so that there is no separation during use, as an expert in the medium could understand. In one embodiment, the superposition of the first clamping portion 104 with the longitudinal side edge 113 of the chassis 102 is between 6 mm and 50 mm (or between approximately 0.25 and 2.0 inches). In this embodiment, the overlapping of the clamping portion with the chassis is generally the same for the four clamping portions. The first holding portion 104 includes two clasps 120. The snaps 120 can be designed to operatively couple the first holding portion 104 with the third holding portion 108 and / or with any other location along the front region 105. While the first portion is shown in Figure 1 of fastener 104 including two clasps 120, in some embodiments, the first fastener portion 104 may include more or less clasps. While Figure 120 depicts brooches 120 of a particular size and shape, in other embodiments, the pins 120 may have different sizes and / or shapes, such as, for example, similar to the clasp 762 shown in Figure 7.

[0057] The second clamping portion 106 is coupled to the second longitudinal side edge portion 115 of the chassis, the second clamping portion 106 superimposed on the chassis 102 along the linear contact points of the attachment 130, thereof such that the first holding portion 104. Together, the first holding portion 104, the rear waist region of the chassis 107, and the second holding portion 106, laterally form the total width "OW_to”170 of the article in the back region. The first holding portion 104 has a first width Pi 122 and the second holding portion 106 has a second width P2 124. The second holding portion 106 includes two pins 120. The pins 120 can be designed to operatively couple the second portion of clamp 106 with the fourth clamp portion 110 and / or with any part along the front region 105. While in Figure 1 the second holding portion 106 is shown including two clasps 120, in some embodiments, the second holding portion 106 may include more or less pins. While Figure 120 depicts brooches 120 of a particular size and shape, in other embodiments, the pins 120 may have different sizes and / or shapes, such as, for example, similar to the clasp 762 shown in Figure 7.

[0058] In some embodiments, the first clamping portion 104 and the second clamping portion 106 can be coupled to the chassis 102 as follows. An end portion 131 of the first holding portion 104 may be temporarily coupled to an end portion 129 of the second holding portion 106. In some of these embodiments, the end portion 131 may be superimposed on the end portion 129 and may be temporarily attached to the end portion 120 by an adhesive. In another of these embodiments, the end portion 131 may be temporarily coupled with the end portion 129 by a perforated seam (not shown) between end portion 129 and end portion 131. The chassis 102 can be temporarily coupled to the first holding portion 104 and the second holding portion 106. Specifically, the rear waist region 107 of the chassis 102 can be substantially placed on the end portion 129 of the first holding portion 104 and the end portion 131 of the second holding portion 106. In other words, the end portion 129 of the first fastening portion 104 and the end portion 131 of the second fastening portion 106 may be placed on a first side of the chassis 102. At least a portion of the first portion of clamping 104 can be folded onto the chassis 102 such that the first clamping portion 104 can be operatively coupled to the chassis 102 approximately at the linear contact points

132 as described above. At least a portion of the second clamping portion 106 may be folded onto the chassis 102 such that the second clamping portion 106 can be operatively coupled to the chassis 102 approximately at the linear contact points 130 as described above. The end portion 129 and the end portion 131 can be released from where they make contact with the other end portion 129 and the end portion 131.

[0059] The third clamping portion 108 is coupled to a third longitudinal side edge portion 119 of the chassis, the third clamping portion 108 superimposed on the chassis 102 along the linear contact points of the attachment 134. The amount of Overlapping is sufficient to reliably connect the clamping portion to the chassis so that there is no separation during use, as an expert in the medium could understand.

[0060] The fourth clamping portion 110 is coupled to the fourth longitudinal side edge portion 121 of the chassis, the first clamping portion 110 superimposed on the chassis 102 along the linear contact points of the attachment 136, thereof so that the first, second or third holding portion 104, 106, 108. Together, the third holding portion 108, the front waist region of the chassis 105, and the fourth holding portion 110, laterally form the total width "OWb" 180 of the absorbent article 100 in the rear region. The third holding portion 108 has a third width P3 126 and the fourth holding portion 110 has a fourth width P4 128. In this embodiment the widths of the four holding portions P1-P4 are substantially the same.

[0061] The third clamping portion 108 and the fourth clamping portion 110 can be operatively coupled to the chassis 102 by temporary engagement of the end portion 138 of the third clamping portion 108 and the end portion 139 of the fourth portion clamping 110 in a manner similar to that described above with reference to the first clamping portion 104 and the second clamping portion 106.

[0062] In other embodiments the width of the clamping portions may vary from one portion to another, as well as from the front to the rear or from side to side. For example, the first holding portion 104 and the second holding portion 106 may have a substantially equal width but a different width than the third holding portion 108 and the fourth holding portion 110. In another embodiment, the first clamping portion and the second clamping portion are a single continuous piece, which goes through the entire chassis perpendicularly and extends beyond the edges of the chassis, forming the clamping portions of the Body. In another embodiment, the third clamping portion and the fourth clamping portion are a single continuous piece, which goes through the entire chassis perpendicularly and extends beyond the edges of the chassis, forming the clamping portions of the Body. In one embodiment, the total width of the rear region "OW_to"170, including the first holding portion 104, the chassis 102 and the second holding portion 106 remain the same, similarly the total width of the front region" OWb "180, including the third holding portion 108, the chassis 102 and the fourth holding portion 110 remain substantially the same.

[0063] In one embodiment, the chassis 102 has a common CW 112 chassis width between 190 mm and 350 mm and preferably approximately 320 mm for all article sizes (the article of the first size, the article of the second size , the article of the third size and the article of the fourth size). In this embodiment, the width of each clamping portion (P_x) is the same at the end of the rear region 150 as at the end of the front region 160. The width of the chassis 112 is the same in all article sizes (eg, Medium, Regular, Large and Extra Large). In this embodiment, the chassis 102 has a rectangular shape or a substantially rectangular shape, where the width is the short dimension. For the first size of the article and the second size of the article, the chassis 102 may also have a first common chassis length CL 111 which is between 800 mm and 880 mm in this embodiment and preferably 860 mm. For the third size of the article and the fourth size of the article, the chassis 102 may have a second common chassis length CL 111, different from the first common chassis length, in this embodiment it is between 860 mm and 1000 mm and preferably 960 mm. The length of the CL 111 chassis in this Figure refers to the dimension and not the actual value.

[0064] As shown in Figure 1, the edge 199 of the chassis 102 may be substantially aligned with the edge 117 of the portion 104 and the portion 106. In some embodiments, the edge 199 may extend beyond the edge 117 of portion 104 and portion 106 (see, for example, Figure 4).

[0065] The articles are assembled in the manufacturing process such that the body holding portions are secured to the chassis 102 where the panels 104, 106, 108 and 110 are arranged between a first layer of the chassis, for example an upper sheet and a second layer of the chassis, for example a bottom sheet. The machine that assembles the article is configured in such a way that the widths of the panel are changed from a first width to a second width to change from manufacturing a first size of article 201 to a second size of article 202. Similarly, when changing to a third size of the article, the widths of the panel are increased, and also in this embodiment, the length of the chassis is increased to a second length of the chassis as well as for the third size of article 303 and the fourth size of article 304. For these changes, the change is completed by executing different programs on the machine and a minimum or even no tool change is required. As an example, there may be no tooling changes such as the replacement of cutting dice that are usually used for cutting leg openings. Instead, it may only be necessary to change the vacuum plate for size changes in the width and length of the panel, which are relatively simple replacements. In some embodiments, the vacuum plates do not even need to be physically replaced, the vacuum plates are sized to fit all panel sizes and depending on the size of the panel, the vacuum ports are enabled or disabled based on the size of the panel.

[0066] Figures 2 and 3 show, in the form of a schematic view, an exemplary general non-limiting embodiment of four absorbent articles of different sizes, in a flat non-contracted state. The first absorbent article

201 designed as a first user size and the second absorbent article

202 designed as a second user size as shown in Figure 2. The third absorbent article 303 as a third user size and the fourth absorbent article 304 as a fourth user size are shown in Figure 3 in its flat non-contracted state . The different sizes of the user, the first and second article 201, 202 are created by designing the widths of the holding portion, for example, P1, P2 or both, for the first user size 201 and the second user size 202 for fit different waist sizes of the 10 user, all with the same chassis width 212 and chassis length 211a and 211b. For example, the article of the first size 201 will have a fixed chassis width "CW" of approximately 320 mm and the first, second, third and fourth clamping portion will have individual widths of approximately 180 mm, while the article of the second size will have widths of approximately 15 200 mm of the first, second, third and fourth clamping portion, although still with the "CW" chassis width of 320 mm. The chassis length 211a and 211b, are approximately 860 mm for the first and second article 201, 202.

[0067] In this embodiment, using the article of the first size 201 as an example, the width of the holding portion "P_x"Can be kept the same for each clamping portion 204, 206, 208, 210 or in another embodiment the first clamping width 204 may be a different width than the second width of clamping portion 206, while maintaining the same width total 203 of the back portion of the article. In another embodiment, the first and second fastener portions 204, 206 may have a first width, and the third and fourth fastener portions 208, 210 may have a second width.

[0068] For the third size 303 and the fourth size 304 (Figure 3), the width of the chassis 311a and 311b "CW" of approximately 320 mm remains the same as the first and second size, however, the widths of the portion of clamp “P_x”And 30 the lengths of the“ CL ”111 chassis are designed differently than the first size 201 and the second size 202 to adjust the different article sizes, much more in this embodiment. The article of the third size 303 will have a fixed chassis width "CW of approximately 320 mm and the first, second, third and fourth width of the clamping portion of approximately 255 mm, while the article of the fourth size 304 will have a width of the first, second, third and fourth clamping portion of approximately 275 mm. The length of the chassis, 311a and 311b, can be between 860 mm and 1000 mm and in one embodiment the length of the chassis 311a and 311b, is approximately 960 mm for the first and second article 210, 202.

[0069] As with the first and second sizes of article 201, 202, the width of the clamping portion Px can be kept the same for each clamping portion 304, 306, 308, 310 or in another embodiment the width of the first clamping portion 304 may have a different width than the second width of clamping portion 306, but maintaining the same total width OW_to 301 of the article at the rear end or the same total width OWb 302 of the article at the front end. In another embodiment, the first and second holding portions 304, 306, may have a first width, and the third and fourth holding portions 308, 310, may have a second width. As the width of the first and second portions increases, the width of the third and fourth portions may decrease, so much so that there is an overlap according to the size of the article to fit the user.

[0070] In the embodiment shown in Figure 3, the article of the third size 303 will have a fixed chassis width "CW" of approximately 320 mm and the first, second, third and fourth width of the holding portion of approximately 255 mm, while the article of the fourth size 304 will have a width of the first, second, third and fourth clamping portion of approximately 275 mm. The length of the chassis, 311a and 311b, can be between 860 mm and 1000 mm and in one embodiment the length of the chassis 311a and 311b, is approximately 960 mm for the first and second article 210, 202.

[0071] Figure 4 is a perspective view of an absorbent article 400 in a second configuration. The absorbent article 400 may be similar and include components similar to the absorbent article 100. By way of example, the absorbent article 400 includes the holding portions 404, 406, 408 and 410, which may be similar to the holding portions 104, 106, 108 and 110 respectively. The second configuration shows the chassis 402 in a position where it would be when the user puts it even if the clamping portions 404, 406, 408 and 410 remain in an uncontracted and unwrapped state. The holding portion 404 includes an edge 465, the holding portion 406 includes an edge 467, the holding portion 408 includes an edge 466 and the holding portion 410 includes an edge 469.

[0072] Figure 5 is a side view of an absorbent article 500 in a third configuration. The absorbent article 500 may be similar and include components similar to the absorbent article 100. By way of example, the absorbent article 500 includes the holding portion 504 (not shown), 506, 508 and 510 (not shown), which they can be similar to the holding portions 104, 106, 108 and 110 respectively. The third configuration shows clamping portions in a wrapped state, as they would be around the user. In this embodiment, the clamping portions may be designed such that the second clamping portion 506 overlaps the third clamping portion 508, and the first clamping portion 504 overlaps the fourth clamping portion 510. The third and fourth holding portion 508, 510, are directly adjacent to the user's skin, while the first holding portion 504 and the second holding portion 506 are partially in the user's skin and partially over the third and fourth holding portion respectively. Having front holding portions that can substantially wrap up to and in some embodiments substantially beyond the midpoint of a person and around toward and against the back of the user, provides a more comfortable fit.

[0073] The opening of the leg 501 is defined by a lower edge 570 of the clamping portions, a second clamping portion 506 and a third clamping portion 508, and the longitudinal edge portions 506 of the chassis 502, with a length L1 114 between the clamping portions along the longitudinal edge of the chassis 502. Due to the rectangular nature of the clamping portions 506 and 508 for the first opening of the leg, the lower edge 570 is significantly adjacent to the waist and is positioned higher than or at least significantly on the user's thigh .

[0074] Figure 6 shows a front clamp portion 608 and a rear clamp portion 606. The front clamp portion 608 may be similar to the third clamp portion 108 and the fourth clamp portion 110, and the clamp portion Rear 606 may be similar to the first holding portion 104 and the second holding portion 106. The front holding portion has a length 674 and the rear holding portion has a length 676. The length of the front clamping portion 608 is greater than the length 676 of the rear clamping portion. A clasp 678 is coupled to the rear fastener portion 606. The length of the front fastener portion 608 is greater than the length of the rear fastener portion 606 to move up or down when fastened and still provide an area of tie for the snap 678, so that the snap 678 does not make contact with the user's skin. In this embodiment, the clasp 678 is substantially the same length as the length 676 of the rear fastening portion 606. In this embodiment, the snap 678 can be applied to the rear fastening portion 606 and can be cut to the required length during the formation of the rear clamping portion 606.

[0075] Figure 7 shows a clamping portion 706, of a chassis 702, the clamping portion 706 includes an elastic panel coupled thereto. The holding portion 706 may be similar to the first holding portion 104 and the second holding portion 106 and include components similar thereto. In one embodiment, the clamping portion 706 has a first panel that is not elastic 752, a second panel that is not elastic 754 and an elastic panel 756. In one embodiment, the elastic panel 756 is between the first panel that is not elastic 752 and the second panel that is not elastic 754. Each panel has a first side edge and a second side edge, distal to the first side edge, and a upper edge 766 and a lower edge 768, forming a rectangle. The first non-elastic panel 752 is connected with the chassis 702 on the first side edge of the first non-elastic panel 752 and a first side edge of the elastic panel 756 on the second side edge, distal the first side edge. A second lateral edge of the elastic panel 756, distal to the first lateral edge, is connected to a first lateral edge of the second panel that is not elastic 754. The second side edge 764, distal the first side edge, has at least one clasp 762 coupled thereto. The holding portion 706 is coupled to the chassis 702 in a manner similar to the holding portions 104, 106, 108, 110 as mentioned above.

[0076] A first seam 758 is formed by the first non-elastic panel 752 second side edge joined with the first side edge of the elastic panel 756. A second seam 760 is formed by the second side edge of the elastic panel 756 joined with the first side edge of the second panel that is not elastic 754.

[0077] Having a portion of the holding portion 706 includes an elastic material that allows a single article to fit a wide variety of user sizes. For example, in one embodiment, only the size of the article is necessary to adjust to the same range of user sizes for the four mentioned articles. This also reduces waste as there is a reduction in the amount of machinery needed to manufacture articles of multiple sizes as well as fewer changes in product size to another product size, thus increasing efficiency in the manufacturing process.

[0078] In one embodiment, the elastic panel 756 has a width between 40 mm and 100 mm and preferably has a width of approximately 68 mm in an embodiment for the first size of the article. The portions that are not elastic can have equal widths which can be approximately 77 mm for example for the first size of the article. For a second size in this embodiment, the elastic panel 756 has a width between 40 mm and 100 mm and preferably has a width of approximately 68 mm in an embodiment for the first size of the article. The non-elastic portions may have equal widths which may be approximately 108 mm for example. There is an overlap of the non-elastic portion and of the elastic portion of approximately 15 mm in this embodiment. This overlay is where the two portions join together. In this embodiment, the two portions are glued. A person skilled in the environment will understand the plurality of methods and procedures for joining the portions together.

[0079] The elastic material can be made of elastic material as understood by experts in the medium. In one embodiment, the elastic material is an elastic material 107 GSM of 3M.

[0080] Figure 8 shows one more embodiment of an absorbent article 800 used by a user. The absorbent article may include a chassis 802. In this embodiment a front clamp portion 808 is wrapped around the user from front to back and extends below the rear clamp portion 806.

858 by the joint between the elastic portion 856 and the first portion that is not elastic 852. A second seam 868 is formed by the joint between the elastic portion 856 and the first portion that is not elastic 854. The width of the front fastening portion 808 is sufficient for what lies between the second seam 860 and the user's skin reducing the abrasive effect of the seam on the skin. In this embodiment, the width of the front clamping portion is between

130 mm and 260 mm and is preferably 180 mm for a first size of a first embodiment. The total width for the first size is 680 mm, and it can be between 630 mm and 830 mm. The width of the front clamping portion is between 205 mm and 335 mm and is preferably 255 mm for a second size of a first embodiment. The total width for a second size is 829 mm, and it can be between 720 mm and 950 mm.

[0081] Figure 9 shows a user with an absorbent article 900 in the third configuration. In this embodiment a front holding portion 908 is wrapped around the user from front to back and extends below the rear holding portion 906. The rear holding portion 906 can be superimposed on the front holding portion 908 a distance 980. The front holding portion 908 may be similar and include components similar to the third holding portion 108, the fourth holding portion 110, and the front holding portion 708. Similarly, the rear holding portion 906 may be similar and include components similar to the first holding portion 104, the second holding portion 106, and the rear holding portion 706. In this embodiment, the length 974 of the front clamping portion 908 is greater than the length 982 of the rear clamping portion 906.

The rear fastening portion 906 includes an elastic panel 956 that lies between a first panel that is not elastic 952 and a second panel that is not elastic 954, and includes a snap 920 similar to snap 120. A first seam 20 is formed 966 by the union between the elastic panel956 and the second panel that is not elastic954. The width of the front fastening portion 908 is sufficient so that it is between the first seam 966 and the user's skin reducing the abrasive effect of the seam on the skin. A second seam 958 is formed by the joint between the elastic panel 856 and the first non-elastic panel 852. The width of the front fastening portion 908 is sufficient so that it is between the first seam 966 and the second seam 958 and the user's skin reducing the abrasive effect of the seam on the skin.

[0082] In this embodiment, the width of the front clamping portion is between 130 mm and 260 mm and is preferably 180 mm for a first size 30 of a first embodiment. The total width for the first size is 680 mm, and it can be between 630 mm and 830 mm. The width of the front clamping portion is between 205 mm and 335 mm and is preferably 255 mm for a second size of a first embodiment. The total width for a second size is 829 mm, and it can be between 720 mm and 950 mm.

[0083] Figure 10 shows a schematic view of absorbent article 100 with certain elements removed for clarity. As shown in Figure 10, the absorbent article 100 includes the holding portions 104, 106, 108, 110; a first core 116; a second core 118; brooches 120; and leg hems 142, 144. In addition, the absorbent article includes an inner layer 130, AD 133 that lies between the inner layer 130 and the second core 118, an outer layer 135, and elastic bands 137. The elastic bands 137 can improve the fit of the absorbent article 100 and They can improve user comfort.

[0084] Figure 11 is a perspective view of an upper side (facing the user) of the second core 118, and Figure 12 is a perspective view of the lower side (facing the other side of the user) of the first core 116. Both the first core 116 and the second core 118 may be composed of similar materials, and they are shaped according to the size of the absorbent article, and whether it is intended for the use of infants, children and / or adults. By way of example, and as shown in Figures 11 and 12, the first core 116 may be larger and substantially hourglass-shaped, while the second core 118 may be smaller, relative to the first core 116, and can be substantially rectangular in shape. In this manner, the absorbent article can include a large surface area of ​​coverage provided by the first core 116, and the increased absorbency provided by the second core 118, without the additional volume of a second core having the same size as the first core.

[0085] The first core 116 is shown with an embossed base and the second core 118 is shown with an embossed top. The embossed upper part of the second core 118 and the embossed base of the first core 116 provide an increased longitudinal flow while reducing the lateral flow, and thus, the shedding is reduced. Stated another way, the embossed upper part of the second core 118 and the embossed base of the first core 116 allow the fluid to move longitudinally towards the front and rear of the user, rather than towards the user's legs. [0086] Both the first core 116 and the second core 118 may be composed of any material suitable for absorbing fluids and secretions including, fibrous material (eg, spongy cellulose pulp), a super absorbent polymer (SAP). English), or the combination of SAP and fibrous material. The SAP can be natural or synthetic and can be biodegradable. Non-limiting examples of SAP include polymers based on acrylate (s) such as sodium acrylate, potassium acrylate, and / or an alkyl acrylate (eg, methyl acrylate, ethyl acrylate, propyl acrylate, butyl acrylate and hexyl acrylate). The absorbency of the diaper may vary depending on whether it is intended for the use of babies, children and / or adults.

[0087] While Figures 11 and 12 represent the first core 116 with a embossed base and a second core 118 with the top embossed (also see, for example, Figures 15 and 16), in some embodiments, an absorbent article it can have a single core without any embossing (see, for example, Figure 13), a single nucleus embossing on both sides (see, for example, Figure 14), and / or other combinations of one or two cores each embossed on one side, on both sides or nowhere. While the Figures show absorbent articles with one or two cores, in some embodiments, the absorbent articles may include more or less cores. While Figures 11, 12, 14 and 15 represent embossed with "lines" of embossed with four spaces, in some embodiments, a core may have more or less embossed lines. In some embodiments, the embossing lines may be adjacent to each other, or it may be a combination of an adjacent embossing line and a space. In this way, different combinations of embossed lines can define a embossed pattern. While Figures 11, 12, 14 and 15 represent substantially embossed throughout the entire width and length of each respective core, in some embodiments, a core may have substantially embossed throughout the entire width and / or length, and / or in a portion of width and / or length.

[0088] Figure 13 is a cross-section of a view of a portion of an absorbent article 1000. The absorbent articles described above generally consist of several layers including an inner layer 1001, an absorbent layer 1002, and an outer layer 1003, as It is shown in Figure 10. In general and applicable to any of the above embodiments, an absorbent layer 1002 may be placed between the inner layer 1001 and the outer layer 1003 of the absorbent article. The absorbent layer 1002 includes a core 1012. The core 1012 may be similar and include characteristics similar to the first core 116 and / or the second core 118.

[0089] The outer layer 1003, which faces the opposite side of the user when the absorbent article is secured to the user, consists of a moisture impermeable fabric. Therefore, the outer layer 1003 can be made of any suitable material to minimize or prevent fluids or other secretions from leaking out of the diaper. Non-limiting examples of materials suitable for the outer layer include polyethylene and / or breathable polyester. According to some embodiments, the outer layer may be a thin film such as, for example, polyethylene film. As will be mentioned in more detail below, the outer layer is generally formed of a plastic resin of any of the previously mentioned materials. The outer layer 1003 that prevents spillage in diapers, also prevents air circulation, creating a warm and humid environment where bacteria and fungi can develop. These bacteria and fungi can cause infectious diseases, unpleasant odors, urinary infections, bladder infections, kidney infections, diaper irritation and the like.

[0090] Figure 14 is a cross-sectional view of a portion of an absorbent article 1100. The absorbent article 1100 may be similar and include components similar to absorbent article 1000. The absorbent article 1100 includes an inner layer 1101, a layer absorbent 1102, and an outer layer 1103. In general and applicable to any of the above embodiments, an absorbent layer 1102 may be placed between the Inner layer 1101 and the outer layer 1103 of the absorbent article. The absorbent layer 1102 includes a core 1112. Unlike the absorbent article 1000, the core 1112 includes an embossed upper part 1112A and an embossed lower part 1112B. In this way, the core 1112 provides an increased longitudinal fluid movement both in the embossed upper part 1112A and in the embossed lower part 1112B of the core 1012, and a reduced lateral flow, thus decreasing the potential spillage on the side of the absorbent article 1100 [0091] Figure 12 is a cross section of a view of a portion of an absorbent article 1200. The absorbent article 1200 may be similar and include components similar to absorbent article 1000 and absorbent article 1100. Absorbent article 1200 includes an inner layer 1201, an absorbent layer 1202, and an outer layer 1203. In general and applicable to any of the Previous embodiments, the absorbent layer 1202 may be placed between the inner layer 1201 and the outer layer 1203 of the absorbent article. The absorbent layer 1202 includes a first core 1212 and a second core 1214. Unlike the absorbent article 1000, but similar to the absorbent article 100, the first core 1212 includes an embossed bottom 1212A and the second core 1214 includes a soothed upper part 1214A . Thus, the first core 1212 and the second core 1212B provide an increased longitudinal fluid movement both in the embossed upper part 1214A and in the embossed lower part 1212B of the second core 1112 and the first core 1214, respectively.

[0092] Figure 16 is a side view of the absorbent article 1200. As shown in Figure 16, the fluid can flow from a user into contact with the absorbent article 1200. The fluid flow is shown in Figure 16 as paths. discontinuous FF1, FF2, and FF3. While the fluid flow is shown as discontinuous paths in Figure 16, in some embodiments, the fluid may not flow along a defined path or paths, in any pattern, and may or may not make contact with the absorbent article in any part or in multiple parts thereof. The fluid can first flow to make contact with, be partially absorbed by, and pass through, the inner layer 1201. The fluid can flow into contact with the embossed upper part 1214A of the second core 1214. The second core 1214 can absorb a portion of the fluid and / or can move longitudinally and / or laterally over and / or into the second core 1214; and a portion of the fluid can pass through the second core 1214 and make contact with the first core 1212. Both the large surface area of ​​the embossed upper part 1214A, and the space created by the embossed upper part 1214A between the inner layer 1201 can direct the flow of the fluid longitudinally towards the front and rear of the user, and away from the edges of the absorbent article 1200 (for example, reduced lateral flow). In this way, when the longitudinal flow increases and / or when the lateral flow decreases, the spillage can be reduced. The first core 1212 may absorb a portion of the fluid and / or may move longitudinally and / or laterally over and / or within the first core 1212; and a portion of the fluid can pass through the first core 1212 and make contact with the outer layer 1203. Both the large surface area of ​​the embossed bottom 1212A, and the space created by the embossed bottom 1212A between the outer layer 1203 can direct the flow of the fluid longitudinally towards the front and rear of the user, and away from the edges of the absorbent article 1200 (for example, reduced lateral flow). In this way, when the longitudinal flow increases and / or when the lateral flow decreases, the spillage can be reduced.

[0093] Figures 17 through 25 show a clamping portion, also referred to as a side panel 1304 for connecting with a chassis 1302, the clamping portion 1304 includes a lamination layer 1350 incorporated therein. The holding portion 1304 may be similar and include components similar to the side panel of the holding portions 104, 106, 108, 110. Therefore, the features of the side panel 1304 can be incorporated into either a rear holding portion or a front holding portion or both. However, it will be very apparent to an expert in the medium that a side panel consistent with the examples shown in Figures 17 through 25 is not limited to the geometry shown in these illustrative embodiments. Instead, an expert in the medium will recognize that any of a wide variety of different shapes, sizes and side panel geometries may be suitable.

[0094] Lamination layer 1350 can consist of a variety of different materials, including a combination of materials, which can provide several benefits that an expert in the medium could recognize. For example, the lamination layer 1350 may have a bulky fiber nonwoven material to provide a softer side panel or an absorbent material to provide additional protection against spills. Alternatively, the lamination layer may include one or more of the following materials: foam rubber, airlaid, tissue or tissue, pulp, SAP, co-form and material obtained by spraying (meltblown material). In one embodiment, the lamination layer consists of a non-woven polypropylene or polyester with a basis weight of between 10 and 75 grams per square meter (GSM), and preferably 48 GSM.

[0095] In one embodiment, as shown in Figures 17 and 20, the side panel 1304 comprises a first layer facing the patient 1354 and a second layer facing outward 1352. A lamination layer 1350 can be found between the first layer 1354 and the second layer 1352. In a preferred embodiment, the lamination layer is more voluminous than the layer facing the patient and the layer facing outwards. In addition, the inclusion of the lamination layer 1350 in the side panel 1304 and the resulting laminated structure allows the use of materials for the opposite layers 1352, 1354 that otherwise may not be suitable for use without the lamination layer, such as softer and more flexible materials. In one embodiment, the opposite layers consist of, for example, non-woven materials of 10 to 20 GSM SMS. Other suitable materials of opposite layers may include nonwoven materials of direct spinning or hydro-entangled polypropylene or polyethylene.

[0096] In the embodiment shown in Figure 17, the lamination layer 1350 has a perimeter that is smaller than the perimeter of the first and second layers such that a portion 1358 of the side panel 1304 without a layer of Lamination completely surrounds the lamination layer. Alternatively, in the embodiment shown in Figure 18, the lamination layer 1350 extends from the upper edge 1366 of a side panel to the lower edge 1368 of a side panel such that a first portion 1370 without a lamination layer is It forms adjacent to chassis 1302 and a second portion 1372 without a lamination layer is formed adjacent to the distal edge 1364 of the side panel. In a further embodiment, as shown in Figures 21 and 22, interleaved strips of the lamination layer 1380a, 1380b and 1380c are located between the layers 1352 and 1354 of the panel. These strips 1380 can be extended from the upper edge 1366 of the panel to the lower edge 1368 of the panel. Alternatively, the strips can extend only part of the distance from the upper edge to the lower edge. One skilled in the art will understand that, according to this invention, the lamination layer can be placed in any of a wide variety of continuous or intermittent distribution, whereby the embodiments mentioned herein are only examples.

[0097] Figures 19 and 20 show another embodiment in which, the side panel 1304 also incorporates an extension portion 1356 that extends beyond the first and second layers 1352 and 1354. This extension portion 1356 may comprise a elastic material, such as an elastic panel. The extension may be attached or bonded 1374 along the distal edge 1364 of the side panel 1304. The extension may also include at least one clasp 1362 coupled to it. This clasp 1362 can be the hook portion of a hook clasp. Alternatively, as shown in Figures 21 and 22, side panel 1304 may include pins similar to pins 120 as previously described in relation to Figure 1.

[0098] As shown in Figure 20, the side panel 1304 may be glued or bonded between an inner layer, or upper sheet, 1330 and an outer layer, or lower sheet, 1335 of chassis 1302 in any manner that is apparent to An expert in the middle.

[0099] The first layer 1354, the lamination layer 1350 and the second layer 1352 can be adhered by the use of glue, heat and pressure adhesion, heat adhesion, pressure adhesion, or ultrasonic adhesion methods. Adhesion patterns can be created in a continuous mode or in a stamped and registered manner. For example, Figure 25 shows a side panel 1304 for attachment to a chassis 1302 as shown in Figure 17. This side panel includes an adhesion pattern 1382 which creates a padded appearance and / or a feeling for the side panel. The adhesion pattern can be created by adhering one or more of the layers at a number of different adhesion sites 1384. Other adhesion patterns can also be used. In addition, the edges of the first and second layers 1354, 1352 can be adhered or sealed along the periphery of the side panel.

[00100] As shown in Figures 23 through 24, an additional adhesion 1402 can be carried out after laminating the lamination layer 1350 on the side panel 1304. This additional adhesion can improve the process of applying and bending the product due to having a "bending line" 1404 on the side panel. This can be done to improve manufacturing performance by reducing debris, reducing inefficiency and out of specification products (folded side panels).

[00101] In one embodiment of this invention, a skin care solution may be applied over the lamination layer 1350. The lamination layer can absorb the skin care solution and then release it into the user's skin. in a period of time. The skin care solution may be a cream, gel or other solution that can provide benefits to the user's skin, such as decreased irritation or ulcers. The skin care solution may include one or more known ingredients to promote healthy skin or prevent skin breakdown. Examples of such ingredients may include, but are not limited to, aloe vera, alpha hydroxy acids (including glycolic, lactic, malic, citric and tartaric acids), soy, grape seed extract, vitamins A, C and E, coenzyme Q10, flavonoids, polyphenols, oatmeal, honey, lactic acid, shea butter, petrolatum, lanolin, petrolatum, cyclomethicone, dimethiconacopoliol, glyceryl stearates, propylene glycol linoleate, silicone, mineral oil, beeswax, caprylic / capric triglycerides, cyclomethicone, hydrogenated castor oil, mineral oil, lanolin, petroleum, petrolatum, silicone, dimethicone, vegetable oils, or any other known ingredient to improve skin condition. In further embodiments, a skin care solution can be applied to other parts of the absorbent article. For example, a skin care solution can be applied in one or more sections of the first portion of the absorbent core 116 or in the second portion of the absorbent core 118.

[00102] As shown in Figure 26, a further embodiment of the invention that may include a sacral lamination layer 1410 may be added to the inner surface 1404 of a rear portion 1406 of the chassis 1302. The sacral lamination layer may be found of such that it is adjacent to a sacral region of the user, around the division of the buttocks and the coccyx, when the absorbent article is used. This lamination layer 1410 can be superimposed with one or more other components that make up the chassis 1302, such as the first portion of the core 116. The sacral lamination layer may include a bulky material that is glued to the upper sheet of the chassis 1330 , either with adhesive or other forms of adhesion known to those skilled in the art. Another embodiment may include a patient oriented layer placed on the sacral lamination layer. The bulky material and the patient-oriented layer may be similar to those described above for use in side panel 1304. As also described above, a skin care solution may be applied over the sacral lamination layer. 25 1410.

[00103] Sacral lamination layer 1410 may have a variety of different shapes, including in rectangular, oval or "butterfly" form. In addition, the sacral lamination layer or the sacral lamination layer and the patient-oriented layer may include one or more of a variety of different embossed shapes or patterns as described herein or as someone skilled in the art would know about them. Embodiments of the invention contemplate absorbent articles using both a lamination layer 1350 on the side panel 1304 and a sacral lamination layer 1410. Alternatively, the lamination layer of the side panel and the sacral lamination layer can be used independently.

[00104] Figures 27 through 29 show embodiments of a method for manufacturing an absorbent article with a rear panel 1304 in accordance with the embodiments shown in Figures 17 through 25. Embodiments of the manufacturing method They may include the following steps: (1) Unwind a continuous canvas 1502 of the first coating layer 1354 of a side panel 1304 of a roll 1506 of coating material in the direction indicated by arrow 1508. (2) Unwind a continuous canvas 1500 of the first lamination layer 1350 for the side panel of a roll 1504 of coating material in the direction indicated by arrow 1510. (3) Providing a small 1512 piece of lamination layer by providing the lamination layer through an access and cutting (also known as cutting and placing by experts in the middle) can also be carried out with a unit of cutting followed by a placement unit - driven either by a mechanical cam or by a servomotor unit, thus providing an intermittent strip 1512 of lamination layer 1350 towards a continuous canvas of the first coating layer 1354 of the side panel 1304. This process may require an adhesive 1516 to be applied to the first coating layer 1502. Access / cut applicator may require a vacuum system in order to hold the lamination layer inside the unit until it is delivered, placed and glued on the first coating layer. (4) Apply a skin care cream 1520 to the portion of the lamination layer 1512 by intermittent application using an aerosol applicator 1518, given extrusion, rotary gravure, or other application process. (5) Unwind a continuous canvas 1522 of the second coating layer 1352 of material for the side panel of a roll 1524 of coating material in the direction indicated by arrow 1526. (6) Match the first coating layer 1502 (with strips of the intermittent lamination layer 1512) with the second coating layer 1522. (7)

Supply the combined layers through an ultrasonic adhesion unit 1528, or a calendering unit (also known as a heat and pressure adhesion unit), including a 1530 pattern roll, to provide a 1382 padded lamination pattern (or another, an aesthetically pleasing pattern) which traps the lamination layer between the coating layers and provides a smooth appearance. (Hot glue lamination can also be used for this application, but without the benefit of a padded appearance) (8) Using the same 1530 pattern roll, or a second medium (which can be another ultrasonic adhesion unit or a pressure unit, or a heating unit), provides an adhesion pattern 1402 on the side panel edges 1304. (9) Add adhesive tabs 120 in the panel assemblies (not shown). An alternative for adhesive tabs as shown would be a continuous hook closure, a hook closure strip 1362 that is shorter than the panel assembly, or a plurality of hook closure strips that can be used to hold the panel. side 1304 with a corresponding side panel or with the front of the product chassis 1302. Embodiments of the portion of the manufacturing process shown in Figure 27 create a continuous panel canvas 1532.

[00105] Figure 28 shows an embodiment of an additional portion of the manufacturing process, including the following steps: (10) Provide a first continuous panel canvas 1532a and a second continuous panel canvas 1532b. The two canvas panels 1532a and 1532b are superimposed in a slightly inclined manner 1534. (11) A cutting and spacing unit 1536 cuts and separates the panel canvases in separate pairs 1538 from the side panels 1304.

[00106] As shown in Figure 29, an embodiment of an additional portion of the manufacturing process includes the following steps: (12) Place the separated pairs 1538 of the side panels 1304 on a continuous canvas 1540 of upper sheet material 1330. (13) Fold one edge of each side panel 1304 under the canvas of the top sheet 1540 along the fold line 1404 as shown by arrows 1542. (14) Marry a continuous canvas

1544 of backsheet material 1335, combined with absorbent cores, with the continuous canvas 1540 or with the top sheet. (15) Adhere one edge of each side panel 1304 between the top sheet 1330 and the back sheet 1335, as shown in Figure 20. In an alternate embodiment of this process, additional side panels are manufactured without the adhesive tabs for use. in a front panel application.
