    ABSORBENT ARTICLE FOR FEMALE CARE, DEFINING A LONGITUDINAL CENTER LINE AND A CROSS-CENTER LINE
    BACKGROUND OF THE INVENTION [01] Absorbent articles, such as sanitary napkins, intimate protectors and incontinence pads, are devices that are typically used in the crotch region of an undergarment. Hygienic pads and intimate protectors are, for example, worn by women in a pair of pants, which is usually positioned between the user's legs, adjacent to the perineum area. Sanitary pads and intimate protectors are designed to absorb and retain body fluids or discharges (for example, menstruation) from women's bodies and to prevent their bodies and clothing from getting dirty. The menstrual period is very problematic for women and many women experience mood swings during the period. Conventional sanitary pads have a white color or a simple combination of light colors to provide a clean appearance. Because of their appearance, such sanitary napkins do not normally impact a woman's feelings because they do not help to decrease or change her mood during menstruation. Several attempts have been made to address this problem. US Patent Application Publication No. 2004/0015145 to Miura, et al., For example, describes a sanitary napkin presenting a printed graphic either over the layer that comes into contact with the body or over the layer that comes in contact with the garment, and that can be seen through the layer that comes into contact with the body. The layer that comes into contact with the body is said to have a certain transmittance to light, so that the graphic can be seen by a woman through the layer to improve her mood during menstruation. Unfortunately, however, such “humor” motor designs do not address other practical concerns
    Petition 870190099057, of 10/03/2019, p. 15/48 / 28 of women. For example, a problem experienced by many women is that leakage can sometimes occur around the periphery of a product, which can become visible upon disposal, and lead to embarrassment for the consumer, and a general loss of confidence in the product. product. Another concern of women is the need to recognize when a pillow is dirty, despite the desire to have aesthetically pleasing designs. Although Miura, et al. refer to conventional mechanisms (for example, embossed walls or channels) to prevent such a leak, they do not provide guidelines for when conventional mechanisms will fail and the leak will occur.
    [02] As such, there is currently a demand for an absorbent article that is both visually appealing, that communicates to a consumer that the pillow is working, or when it is dirty, but that also helps to mask the leakage of body fluids in certain locations. , thereby offering reduction of uncomfortable feelings / embarrassment with excessive menstruation. Therefore, there is a demand for absorbent articles, which provide functional indications to the user, while avoiding embarrassment.
    SUMMARY OF THE INVENTION [03] According to an embodiment of the present invention, an absorbent article is described which defines a longitudinal center line and a transverse center line. The article comprises a top sheet, baffle and an absorbent core disposed between the top sheet and the baffle. The top sheet and the baffle extend outwardly from a circumferential edge of the absorbent core and to a first longitudinally extending periphery portion located on one side of the longitudinal centerline, a second longitudinally extending periphery portion along the other side of the longitudinal centerline, a third portion of the periphery that extends laterally located on one side
    Petition 870190099057, of 10/03/2019, p. 16/48 / 28 of the transverse center line and between the respective embedded dimensions (inboard) of the first peripheral zone and the second peripheral zone, and a fourth periphery portion that extends laterally located on the other side of the transverse center line and between the respective embedded dimensions of the first and second peripheral zones. A first transition zone extends circumferentially around an inner zone adjacent to the third peripheral zone and a second transition zone that extends circumferentially around the inner zone adjacent to the fourth peripheral zone. A first printed pattern of discrete graphic objects is positioned within the first peripheral zone and extends at least partially to the first transition zone, the second transition zone or both. A second printed pattern of discrete graphic objects is positioned within the second peripheral zone and extends at least partially to the first transition zone, the second transition zone or both. The first printed pattern is asymmetric with respect to the second printed pattern around both longitudinal and transverse center lines. The first printed pattern and the second printed pattern are visible from a surface that faces the body of the top sheet. Most of the interior area is free of printed graphic objects.
    [04] In accordance with another embodiment of the present invention, an absorbent article for female care is described, which comprises a passive masking component and an active masking component. The passive masking component includes a first printed pattern of discrete graphic objects positioned within a first peripheral zone and extending at least partially to a first transition zone and / or a second transition zone of the absorbent article, and a second pattern printing of discrete graphic objects positioned within a second peripheral zone and extending at least partially to the first transition zone and / or the second
    Petition 870190099057, of 10/03/2019, p. 17/48 / 28 transition. The first print pattern is asymmetrical with respect to the second print pattern around both longitudinal and transverse center lines, and the first printed pattern and the second printed pattern are visible from a surface that faces the body of a sheet. top. A majority of the interior area of the absorbent article is also free of printed graphic objects. In addition, the active masking component is positioned within the first peripheral zone, the second peripheral zone, the first transition zone, the second transition zone or a combination thereof.
    [05] In one embodiment, an active stain masking component can be employed, which includes a bleaching composition. The bleaching composition may include an agglutination agent, an oxidizing agent or a combination thereof. The bleaching composition can be arranged within the first transition zone, the second transition zone or both.

    DETAILED DESCRIPTION OF REPRESENTATIVE MODALITIES
    DEFINITIONS
    As used here, the term "body-facing surface" generally refers to a surface that faces outward from an absorbent article, which is intended to be disposed towards, or placed adjacent to, the body of a user during ordinary use. That surface can be defined by a top sheet, which also includes a surface that faces back inward.
    [09] As used here, the term “surface facing the garment”, in general, refers to a surface that back out of an absorbent article, which is intended to be disposed away from the body of a user during ordinary use. Typically, the surface is positioned adjacent to the user's undergarments when the article is being used. This surface can be defined by a deflector, which also includes an opposite inwardly facing surface.
    DETAILED DESCRIPTION [10] Reference will now be made in detail to various embodiments of the invention, one or more examples of which are shown below. Each example is provided by way of explaining the invention, not limiting the invention. Indeed, it will be apparent to those skilled in the art that various modifications and variations can be made to the present invention, without departing from the scope or spirit of the invention. For example, characteristics
    Petition 870190099057, of 10/03/2019, p. 19/48 / 28 illustrated or described as part of one embodiment, can be used in another embodiment to provide yet another embodiment. Therefore, it is intended that the present invention will cover such modifications and variations as they fall within the scope of the appended claims and their equivalents.
    Generally speaking, the present invention is directed to an absorbent article for female care, which contains multiple printed patterns of graphic objects visible from a surface facing the body. The layout and design of the patterns are carefully selected in the present invention to achieve a synergistic masking effect, which helps to visually disguise the presence of body fluids or stains around the periphery of the article. Such a "passive" stain masking agent is achieved, in part, through the use of printed patterns, which are distributed in an asymmetrical manner around both the longitudinal and transverse center lines of the article. Asymmetry can be provided in a variety of ways, such as through the use of objects of different sizes, colors, shapes and designs. Among other things, the asymmetric nature of the patterns allows the color of the body fluid to better match the visual nature of the patterns, and draws the user's attention away from the areas in which spots are located. In addition to such an asymmetric distribution, the printed patterns are also strategically positioned within the article, to produce the desired optical impact. Namely, the patterns are located at, or close to, the periphery of the article and extend, at least partially, to portions of the body-facing surface, which overlap the absorbent core. Once again, this partial overlapping of the absorbent core region helps to further improve the article's ability to “passively” mask stains.
    [11] The present inventors also found another aspect of the
    Petition 870190099057, of 10/03/2019, p. 20/48 / 28 synergistic pattern design that must balance the optical effects of "passive" stain masking with other functional indications. More particularly, while stain masking is an important feature, equally important is the ability to detect whether the absorbent article is functioning properly, or if it needs to be changed. In this regard, the pattern design of the present invention is such that a majority of an interior area of the absorbent article is generally free of printed graphic objects. In addition to providing the user with the ability to better detect the presence of body fluids during use, the absence of objects printed in certain areas of the article also further enhances the overall distinctive nature of the patterns, and gives a sense of cleanness to the use for that purpose. portion of the product, which will be in contact with the user's most intimate areas.
    [12] Referring to Figure 1, a particular embodiment of the absorbent article for female care 20 of the present invention will now be described in more detail. As shown, the feminine care absorbent article 20 (e.g., feminine care pad or sanitary napkin) includes a top sheet 26, a baffle 28 and an absorbent core 30 positioned between the top sheet 26 and the baffle 28 The top sheet 26 defines a surface that faces the body 27 of the absorbent article 20. The absorbent core 30 is positioned inwardly from the outer periphery of the absorbent article 20 and includes a side that faces the adjacent positioned body to the top sheet 26 and a surface that faces the garment positioned adjacent to the baffle 28. Typically, the top sheet 26 and the baffle 28 are joined by adhesive bonding, ultrasonic bonding or any other suitable joining method known in the technique, the sealed edges defined a global sealed peripheral edge 99 of article 20. Article 20 can assume several geometries, but, in general, it will present lateral sides and and opposite longitudinal ends.
    Petition 870190099057, of 10/03/2019, p. 21/48 / 28
    The top sheet 26, in general, is designed to come into contact with the user's body and be permeable to liquids. The liquid-permeable top sheet 26 has an outward-facing surface that can come into contact with the user's body and receive aqueous fluids from the body. The top sheet 26 is provided for comfort and conformability and works to direct body exudations away from the body, through the top sheet 26 and towards the absorbent core 30. The top sheet 26 retains little or no liquid in its structure, so that it provides a relatively comfortable and non-irritating surface close to the tissues inside the lobby of a female user. The top sheet 26 can be constructed of any woven or non-woven material, which is easily penetrated by bodily exudations containing the surface of the deflector. Examples of suitable materials include rayon, bonded carded wefts of polyester, polypropylene, polyethylene, nylon, or other heat-bondable fibers, polyolefins, such as polypropylene and polyethylene copolymers, linear low density polyethylene, and aliphatic esters, such as poly ( lactic acid). Finely perforated film webs and pure material can also be used. A specific example of a suitable top sheet material is a bonded carded web made of polypropylene and polyethylene, such as that used as a top sheet stock for KOTEX® intimate protectors and obtainable from Sandier Corporation (Germany). U.S. Patent Nos. 4,801,494 to Datta, et al., And 4,908,026 to Sukiennik, et al., Teach several other top sheet materials, which can be used in the present invention.
    [13] The top sheet 26 can also contain a plurality of openings (not shown) formed throughout, to allow fluid from the body to pass more readily to the absorbent core 30. The openings can be arranged at random or uniform over the entire top sheet 26, or they can be positioned only on the narrow longitudinal strip or band arranged along the longitudinal axis of the article
    Petition 870190099057, of 10/03/2019, p. 22/48 / 28 absorbent 20. The openings allow the rapid penetration of body fluid down to the absorbent core 30. The size, shape, diameter and number of openings can be varied to suit some particular needs.
    [14] Deflector 28, in general, is impermeable to liquids and designed to face the inner surface, that is, the crotch portion of an intimate garment (not shown). The baffle 28 can allow air or steam to pass out of the absorbent article 20, while still blocking the passage of liquids. Any liquid impermeable material, in general, can be used to form deflector 28. For example, a suitable material that can be used is a microporous polymeric film, such as polyethylene or polypropylene. In particular embodiments, a polyethylene film is used, which has a thickness in the range of about 0.005 mm to about 0.127 mm (about 0.2 mils to about 5.0 mils), and particularly between about 0.013 mm at about 0.076 mm (about 0.5 to about 3.0 mils). A specific example of a deflector material is a polyethylene film, such as that used in KOTEX8 intimate protectors and obtainable from Pliant Corporation, Schaumburg, IL, USA.
    [15] As indicated above, an absorbent core 30 is positioned between the top sheet 26 and the baffle 28, which provides the ability to absorb and retain body exudates. The absorbent core 30 can be formed from a variety of different materials and contain any number of layers desired. For example, typically, core 30 includes one or more layers of cellulosic fiber absorbent weft material (for example, wood pulp fibers), other natural fibers, synthetic fibers, woven or non-woven sheets, cotton mesh netting or other stabilizing structures, superabsorbent material, binder materials, surfactants, selected hydrophobic and hydrophilic materials, pigments,
    Petition 870190099057, of 10/03/2019, p. 23/48 / 28 lotions, odor control agents or the like, as well as combinations thereof. In a particular embodiment, the absorbent weft material includes a cellulosic fluff matrix, and can also include superabsorbent material. Cellulosic fluff may comprise a combination of wood pulp fluff. A preferred type of fluff is identified with the trade name NB 416, available from Weyerhaeuser Corp., and is a highly absorbent, bleached wood pulp, containing primarily softwood fibers. Absorbent materials can be formed into a weft structure, using various conventional methods and techniques. For example, the absorbent web can be formed with a dry forming technique, an air forming technique, a wet forming technique, a foaming technique, or the like, as well as combinations thereof. A non-woven coform material can also be employed. Methods and apparatus for carrying out such techniques are well known in the art.
    [16] The top sheet 26 can be held in relation to the absorbent core 30 by connecting all or a portion of the surfaces adjacent to each other. A variety of connection mechanisms known to the person skilled in the art can be used to achieve any such stuck relationship. Examples of such mechanisms include, but are not limited to, applying adhesives in a variety of patterns between the two adjacent surfaces, entangling at least portions of the absorbent's adjacent surface with portions of the adjacent surface of the cover, or melting at least portions of the adjacent surface of the cover to portions of the adjacent surface of the absorbent. Typically, the top sheet 26 extends over the upper body-facing surface of the absorbent core 30, but alternatively it can extend around the article to partially or entirely surround or enclose the absorbent core. Alternatively, the top sheet 26 and the baffle 28 can
    Petition 870190099057, of 10/03/2019, p. 24/48 / 28 present peripheral margins, which extend outwardly beyond the peripheral, terminal edges of the absorbent core 30, and the extending margins can be joined together, to surround or enclose, partially or entirely, the absorbent core .
    [17] Although not required, the required article 20 may also contain other additional layers, as is known in the art. In Figure 1, for example, a liquid permeable assimilation layer 32 is positioned vertically between the top sheet 26 and the absorbent core 30. The assimilation layer 32 can be made of a material, which is capable of transferring quickly, in the z direction, body fluid that is delivered to the top sheet 26. The assimilation layer 32 can, in general, have any desired shape and / or size. In one embodiment, the assimilation layer 32 has a rectangular shape, with a length equal to or less than the overall length of the absorbent article 20, and a width less than the width of the absorbent article 20. For example, a length of between about 150 mm to about 300 mm and a width of between about 10 mm to about 60 mm can be used. Any one of a variety of different materials is capable of being used for the assimilation layer 32, to perform the functions mentioned above. The material can be synthetic, cellulosic or a combination of synthetic and cellulosic materials. For example, cellulosic tissue paper dispersed by air may be suitable for use in the assimilation layer 32. Cellulosic tissue paper dispersed by air can have a weight ranging from about 10 grams per square meter (g / m 2 ) to about 300 g / m 2 , and, in some embodiments, between about 40 g / m 2 to about 150 g / m 2 . Air-dispersed tissue paper can be formed from hardwood and / or softwood fibers. Air-dispersed tissue paper has a fine pore structure and provides excellent capillary action, especially for menstruation.
    Petition 870190099057, of 10/03/2019, p. 25/48 / 28
    The absorbent article 20 may also contain a transfer delay layer (not shown) positioned between the assimilation layer 32 and the absorbent core 30. The transfer delay layer may contain a material that is substantially hydrophobic, such as a non-woven web. woven fabric composed of polypropylene, polyethylene, polyester, etc. An example of a suitable material for the transfer retardation layer is a spunbond weave composed of fibers with multiple polypropylene lobes. Additional examples of transfer retardant layer materials include spunbond wefts composed of polypropylene fibers, which can be rounded, with three or multiple wires in the shape of the cross section, and which can be hollow or solid in structure. Typically, the wefts are bonded, such as by thermal bonding, to about 3% to about 30% of the weft area. Other examples of suitable materials, which can be used for the transfer delay layer 36, are described in US Patent Nos. 4,798,603 to Meyer, et al. and 5,248,309 for Serbiak, et al. To adjust performance, the transfer delay layer can also be treated with a selected amount of surfactant to increase its initial wettability. The transfer delay layer typically has a lower weight than that of the other absorbent members. For example, the weight of the transfer delay layer 36 is typically less than about 250 grams per square meter (g / m 2 ), and in some embodiments, between about 40 g / m 2 to about 200 g / m 2 .
    [18] The absorbent article 20 may also include wing portions 42, which extend laterally, which can be integrally connected to the lateral regions along the intermediate portion of the article. For example, the wing portions 42 may be members provided separately, which are subsequently attached or otherwise operatively joined to the intermediate portion of the article. In other configurations, the wing portions
    Petition 870190099057, of 10/03/2019, p. 26/48 / 28 can be formed in a unitary manner with one or more components of the article. As shown in a representative manner in Figure 1, for example, each or both of the wing portions 42 can be formed from a corresponding operative extension of the material used to form the top sheet 26. Alternatively, each or both portions wing shapes 42 can be formed from a corresponding operative extension of the material employed to form the deflector 28, or formed from a corresponding operative combination of the top sheet and deflector materials.
    [19] Regardless of the particular configuration of the layers used in forming the absorbent article 20, a plurality of objects are printed in patterns, so that they are visible from the surface facing the body 27. Particular patterns are carefully selected to provide a unique visual appearance that both aids in masking “passive” stains and provides a functional indication to the user. More particularly, as shown in Figure 1, the top sheet 26 and the baffle 28 extend outwardly from a circumferential edge 50 of the absorbent core 30 and to a first longitudinally extending peripheral portion 52 located on the side a longitudinal centerline "L" and a second longitudinally extending portion 54, located along the other side of the longitudinal centerline. The top sheet 26 and the baffle 28 can also extend outwardly from the circumferential edge 50 to a third peripherally portion 72, which extends laterally, which is located on one side of a transverse center line "T", and a fourth portion of periphery 74, which extends laterally, located along the other side of the transverse center line. As shown, the third periphery portion 72 and the fourth periphery portion 74 are located between the longitudinal embedded dimensions 81 and 83, of the first peripheral zone 52 and the second zone
    Petition 870190099057, of 10/03/2019, p. 27/48 / 28 peripheral 54, respectively. Although not necessarily required, in the embodiment shown in Figure 1, the periphery portions 52, 54, 72 and 74, together, extend around the entire periphery of article 20 to an edge 99.
    To help reduce the visibility of spots around the outer periphery, particularly at the side edges, the present inventors have found that a pattern of graphic objects can be printed within both the first peripheral zone 52 and the second peripheral zone 54. The patterns can be printed on any layer of article 20 as far as they are visible from the surface facing the body 27. For example, patterns can be printed on the surface facing away from the top sheet 26, so that they are readily visible. Likewise, patterns can be printed on the surface facing the baffle 28, in such a way that they still remain visible from the surface facing the body 27. Independently, a first printed pattern of objects discrete graphics 93 is positioned within the first peripheral zone 52 and a second printed pattern of discrete graphic objects 95 is positioned within the second peripheral zone 54.
    As shown, the first and second printed patterns are asymmetrical around both the longitudinal centerline "L" and the transverse centerline "T". The use of asymmetrical printed patterns on longitudinally extending peripheral portions can help to provide a unique visual appearance and also help to mask spots in those places, where such masking is very necessary. However, it should be understood that the presence of printed patterns is in no way limited to these locations. Referring again to Figure 1, for example, a third printed pattern of discrete graphic objects 92 can also be positioned within the third peripheral zone 72 and a
    Petition 870190099057, of 10/03/2019, p. 28/48 / 28 fourth discrete graphic object pattern 94 can be positioned within the fourth peripheral zone 74. As described above, these patterns can be printed over the baffle 28, the top sheet 26, etc., as long as they are visible to the user from the surface facing the body 27. The third pattern can also be asymmetrical with respect to the fourth pattern around both longitudinal and transverse center lines. In this way, the entire periphery can have a global asymmetrical appearance, which is both desirable for “pre-use” visual appearances, as well as to provide passive “post-use” masking of spots. Obviously, it must be understood that the presence of a pattern around the entire periphery is by no means required. In certain embodiments, for example, the third peripheral zone 72 and / or the fourth peripheral zone 74 may be free of printed graphic objects.
    [20] In addition to selectively controlling the visual appearance of patterns printed along the periphery, the present inventors have also found that the ability to passively mask stains can even be further enhanced by extending at least a portion of the patterns to regions of the region. surface facing the body, overlapping the absorbent core. Such overlapping with the absorbent core region helps to further improve the article's ability to “passively” mask stains. In Figure 1, for example, the absorbent article defines a first transition zone 62, which extends circumferentially around an inner zone 80 on one side of the transverse center line "T", so that it is adjacent to the third zone peripheral 72 to both longitudinal peripheral zones 52 and 54. A second transition zone 64 also extends circumferentially around the inner zone 80 on the other side of the transverse center line "T", so that it is adjacent to the fourth peripheral zone 74 and both longitudinal peripheral zones 52 and 54. In the illustrated embodiment, the interior zone 80 is the region
    Petition 870190099057, of 10/03/2019, p. 29/48 / 28 visible from article 20 (e.g. top sheet 26, baffle 28 or absorbent core 30), which corresponds to assimilation layer 32, transition zones 62 and 64 are the visible regions of article 20, corresponding to the portions of the core 30 that extend beyond the assimilation layer 32. Although not required, the transition zones can therefore extend together around the entire periphery of the inner zone 80. As reflected in Figure 1, typically , the interior area 80 constitutes from about 25% to about 75%, and, in some embodiments, from about 35% to about 65% of the combined surface area of the interior transition zones.
    [21] Regardless of the particular configuration, the presence of printed patterns within one or more transition zones can help to give the overall appearance of a more cohesive or coordinated appearance, while minimizing distractions from the graphic elements, for the purpose to provide functional indication or a funny or entertaining appearance. For example, referring again to Figure 1, the first printed pattern of graphic objects 93 and the second printed pattern of graphic objects 95 both extend to the first transition zone 62 and the second transition zone 64. Once moreover, this can be accomplished by printing objects over the baffle 28, the top sheet 26, etc., in such a way that the overall patterns are asymmetrical around both the longitudinal centerline “L” and the line of transverse center “T”. If desired, the third printed pattern of graphic objects 92 can extend to the first transition zone 62 and / or and the fourth printed pattern of graphic objects 94 can extend to the second transition zone 64.
    [22] Asymmetry in the printed patterns described above can be provided in a variety of ways, such as through the use of objects of different sizes, colors, shapes and designs. Such asymmetry performs the dual functions of providing a unique and distinctive “pre-use” visual appearance, and providing a “post-use” visual appearance that can
    Petition 870190099057, of 10/03/2019, p. 30/48 / 28 passively mask stains after the product has been used. The asymmetry indicates that the patterns do not present simple symmetry, such as reflection, rotation and translation symmetries, and, preferably, they do not present Glide, roto-reflection, helical or non-isometric symmetries. While being asymmetrical, patterns can nevertheless provide an asymmetric balance to the extent that several smaller graphic objects on one side can be “balanced” by a large graphic object on the other side, or smaller objects can be positioned even further away from the center. than larger objects. Alternatively, a darker object can be similarly balanced by several lighter objects. It should also be noted that, although graphic objects 93 and 95 are shown here as having relatively simple formats, this is purely for exemplary purposes. Virtually any shape or design can be employed, such as points, ovals, triangles, squares, rectangles, flowers, butterflies, stars, hearts, spirals, double spirals, clothoids, horn spirals, polynomial double spirals, Euler double spirals, spirals parametric doubles, etc. In fact, it is generally preferable that the graphic objects are of a more complicated nature and that they have some degree of curvature and color to provide a more complex visual perception and that aid in the overall masking effect of the article. For example, Figures 4-9, in general, illustrate more complex graphic objects, which can be used in the present invention.
    [23] Specific graphic objects can also be selected in such a way that, although asymmetrical, they are visually coordinated with the surrounding environment, to provide a perception that the product will perform better. The surrounding environment can, for example, be the packaging (for example, wrapping, bag, etc.), within which the absorbent article is initially supplied, as described in US Patent Application Publication No. 2005/0154365 to Zander , et al., the
    Petition 870190099057, of 10/03/2019, p. 31/48 / 28 which is incorporated herein, in its entirety, by reference to it, for all purposes. Objects can also be coordinated visually with a garment, as described in US Patent Application Publication No. 2008/0058748 by Seifert, et al., Which is also incorporated herein in its entirety by reference to it , for all purposes. Visually coordinated graphic objects are those in which two or more visual characteristics either combine or are urged to combine.
    In certain cases, graphics objects may also be arranged to impart an illusion when viewed artir w of a focal point of the particular user. For example, the arrangement of graphic objects in reciprocal relation can form an optical illusion of perceptible movement as at least one of the objects appears to move away from an edge of the body. Exemplary objects to provide such an illusory pattern may include geometric, spirals, anomalous movement, rotation, color change, peripheral displacement, positive after image blurs, scintillation grid, stereoscopy and chromoesteropsis, contraction and expansion, contrast polarities, convection , chromatic assimilation, etc., as described in US Patent Application Publications Nos. 2009/0157021 for Sullivan, et al., And 2005/0268371 for Meekins, which are incorporated herein, in their entirety, by reference to them, for all purposes. In another modality, graphic objects of different hues can be used to create a perception of depth within the absorbent article by a user looking over the viewing surface of the top sheet. Such illusory patterns are described in US Patent Application Publication No. 2003/0114811 to Christon, et al., Which is incorporated herein in its entirety by reference to it for all purposes. Regardless of the mechanism employed, optical illusions can make the user perceive the stain as being different or deeper in the product than what it really is, and,
    Petition 870190099057, of 10/03/2019, p. 32/48 / 28 therefore, intensifies passive masking.
    The graphic objects referenced above, in general, are passive to the extent that they do not change during the use of the product. In certain cases, however, it may be desired to incorporate one or more active graphic objects into the printed patterns to further enhance the “post-use” impact on the user. For example, one or more active graphic objects can be used, which “disappear” or “appear” from view at a certain moment. Active graphics can be employed, which are soluble in aqueous solutions and therefore fade in color when in contact with urine. Such charts are described, for example, in U.S. Patent No. 6,307,119 to Cammarota, et al. and 4,022,211 for Timmons, et al., which is incorporated herein, in its entirety, by reference to it, for all purposes. Active graphics can also be employed, which appear over time due to exposure in time intervals, temperature levels, oxygen levels, etc., as described in U.S. Patent Nos. 5,508,088 to Haas, et al .; 5,053,339 to Patel; 5,045,283 to Patel; 4,987,849 to Sherman; 4,903,254 to Haas; 4,812,053 to Bhattacharjee; and 4,292,916 to Bradley, et al; which are incorporated herein, in their entirety, by reference to them, for all purposes. In addition to intensifying masking, such interactive graphic objects can also provide additional performance indications to the user. For example, the appearance of graphic objects can serve as an indicator of humidity or empty volume, as described in US Patent No. 7,322,472 to Swiecicki, et al., Which is incorporated herein in its entirety by reference to it, for all purposes.
    [24] Although the presence of asymmetric patterns within the peripheral and transition zones can help to provide the desired coordinated visual appearance, it is also desired to keep a majority of the interior zone free of graphic objects, so that the user is endowed with a
    Petition 870190099057, of 10/03/2019, p. 33/48 / 28 distinctive visual indication that the product is working as expected. More specifically, at least 50% of the surface area facing the body, located inside the interior, is free of printed graphic objects. In certain embodiments, at least 60% of the surface area, and in some embodiments, from 75% to 100% of the interior area's surface area is free of printed graphic objects. Obviously, a portion of the interior area may still contain graphic objects. In the embodiment shown in Figure 1, for example, a graphic object 92a is shown inside the interior. When present, such graphic objects can be distributed symmetrically or asymmetrically around the transverse and / or longitudinal center lines. It should be understood that the term "free of printed graphic objects" does not preclude the presence of any printed ink. The expression simply means that graphic objects (for example, flowers, spirals, dots, etc.) having a defined shape and size are not located within a given area. For example, the entire surface can be printed with colored ink, and after that, a pattern of graphic objects can be printed on it, which covers less than 50% of the surface area. Despite the fact that the entire surface contains a printed ink, most of the interior area is still considered to be free of printed graphic objects.
    [25] Generally speaking, the printed "patterns" of the present invention include a set of graphic objects within a given area. However, as mentioned, graphic objects do not need to be printed on the same surface within that area. For example, in the embodiment shown in Figure 1, at least a portion of graphic objects 93 are printed over the baffle 28, as illustrated graphically by object 93a. The object 93a can still be visible on the surface facing the body 27 through the use of a top sheet 26 having a degree of transmittance to light. Within the same pattern, another portion of
    Petition 870190099057, of 10/03/2019, p. 34/48 / 28 objects 93 can also be printed on top sheet 26, as illustrated graphically by object 93b. In addition to enhancing manufacturing flexibility, the use of patterns with graphic objects located on multiple surfaces can provide a distinctive visual appearance, which facilitates the masking of blemishes and which helps to provide other functional indications to the user. Independently, the graphic objects together form a pattern that is visible and recognizable by the user.
    [26] The ability to print patterns over both the top sheet and the baffle is best illustrated in Figures 2-3. Referring to Figure 2, for example, one embodiment of a deflector 128 is shown, which contains a surface 129, which faces inwards towards the body during use. In this particular embodiment, surface 129 is printed with multiple patterns of graphic objects around its periphery and interior. Figure 3 shows the baffle 128 after being covered by an absorbent core 130 and a top sheet 126, which defines a surface that faces the body 131. Due to the fact that the top sheet 128 is transmissive to light, the graphic objects printed over the baffle 128 remain visible from the surface facing the body 131, although in a lighter shade. However, in those places where the absorbent core 130 covers the baffle 128, the graphic objects in the baffle 128 are not visible from the surface facing the body. However, graphic objects are printed over the top sheet 126, so that, together with the graphic objects in the baffle 128, a unique and distinctive pattern arrangement is created.
    [27] If desired, other aspects of the absorbent article can also be controlled to enhance the masking of passive stains. For example, a reflective material (eg coating, pigment, etc.) can be used in one or more layers of the article to intensify
    Petition 870190099057, of 10/03/2019, p. 35/48 / 28 the intensities of light that emanate from the colored surfaces, although even further decreasing the perception of light staining. Examples of such reflective materials are described in more detail in WO 2003/013406 to Benecke, et al., Which is incorporated herein, in its entirety, by reference to it, for all purposes. Opacifying agents (for example, titanium dioxide, calcium carbonate, etc.) can also be employed to assist in masking absorbed fluids, as described in US Patent No. 4,801,494 to Datta, et al., Which is here incorporated, in its entirety, by reference to it, for all purposes.
    [28] As emphasized above, the unique and distinctive patterning of the present invention enhances 'passive' blotting. The present inventors have found, however, that the use of an "active" masking component in combination with such unique patterns has a synergistic impact on the user's overall experience with the product. For example, the active masking component can physically change the color of the body fluid or direct it to a more hidden location in the article. In any case, the printed patterns of the present invention can be coordinated with the active masking component to enhance the desired visual impact.
    [29] In certain embodiments, for example, the active masking component may include one or more structural elements formed on a layer of the article to help guide body fluid in the desired direction (for example, along the body-facing surface) of the article) to minimize the visibility of stains within the periphery, but still to provide a visual indication regarding adjustment and protection against leakage. Suitable structural elements may include, for example, embossing, areas with depressions, areas with elevations, openings, etc. The particular arrangement of structural elements, in general, is not
    Petition 870190099057, of 10/03/2019, p. 36/48 / 28 critical. In one embodiment, for example, embossed channels are employed, which deform the top sheet and selected portions of the absorbent core. The embossing pattern not only creates an aesthetically pleasing surface, but also the channels facilitate the assimilation of menstruation by the fact that the fluid will tend to flow along the densified edges of the channels instead of accumulating at contact points of the top sheet 26. The embossed channels can be positioned adjacent the perimeter edges of the absorbent core in a symmetrical or asymmetrical manner. Referring to Figure 1 again, for example, symmetrical embossed channels 98 are shown, which are provided within the inner zone 80 near the upper and lower circumferential edge of the assimilation layer 32.
    [30] In addition to the embossed channels, other structural elements can also be employed to help guide the fluid and act as an “active” masking component. As an example, US Patent No. 5,614,295 to Quincy, III, et al., Which is incorporated herein, in its entirety, by reference to it, describes a fibrous web, which is specifically configured to deliver liquid in the direction fiber orientation. The web is formed from a first fiber zone treated with a surfactant and a second fiber zone exposed to a corona field. Another suitable fluid guide may include a permeable sheet (for example, a non-woven web) adsorbed with an amphiphilic protein (for example, milk protein) to define a gradient distribution of a coating with amphiphilic protein over at least one permeable leaf size. This provides controlled wettability over at least one dimension of the permeable, liquid flow control material. Such materials are described in more detail in U.S. Patent No. 5,912,194 to Everhart, et al., Which is incorporated herein, in its entirety, by reference to it, for all purposes. In yet another modality, the
    Petition 870190099057, of 10/03/2019, p. 37/48 / 28 fluid glutton can be a nonwoven web having a high grammage and / or high devier, as described in US Patent No. 4,892,534 to Datta, et al., Which is incorporated herein in its totality, by reference to it, for all purposes. For example, the weight can vary from about 16.9 to 33.9 g / m 2 (0.5 to 1.0 ounces per square yard), and, in some modalities, from about 23.7 to 33, 9 g / m 2 (0.7 to 1.0 ounces per square yard), and the denier can vary from about 3 to about 15, and, in some embodiments, from about 4 to about 12. Such wefts high grammage and high denier contain large passageways that extend downwardly through the thickness of the web and have the ability to draw a greater amount of body fluid away from the visible surface, thereby actively masking visible stains. Regardless of the particular mechanism employed, however, such fluid guides can assist in controlling or coordinating the stain pattern, thereby "actively" intensifying the masking effect of the present invention. Fluid guides can be used in the center and / or on the periphery of the article, as desired.
    [31] A chemical treatment can also be employed as an active masking component, which alters the body's own fluid. In one embodiment, for example, the treatment may be a bleaching composition that agglutinates (agglomerates) red blood cells in the blood and during periods and that limits the extent to which the red color of periods is visible. Such a composition includes a surfactant, as described in U.S. Patent No. 6,350,711 to Potts, et al., Which is incorporated herein in its entirety by reference to it. Particular examples of such surfactants are Pluronic® surfactants (copolymer surfactant in triblocks). Another suitable composition, which can help to agglutinate (agglomerate) cells, includes one or more inorganic salts, which contain a polyvalent anion (eg, divalent, trivalent, etc.), such as sulfate
    Petition 870190099057, of 10/03/2019, p. 38/48 / 28 (SO 4 2- ), phosphate (PO4 3 ·), carbonate (CO3 2 ·), oxide (O -2 ), etc., and a monovalent cation, such as sodium (Na +), potassium ( K +), lithium (Li +), ammonium (NH 4 +), etc. Alkali metal cations are particularly desirable. Specific examples of salts formed from such ions include, for example, disodium sulfate (Na2SO4), dipotassium sulfate (K2SO4), disodium carbonate (Na2CO3), dipotassium carbonate (K2CO3), monosodium phosphate (NaH2PO4), disodium phosphate (Na2HPO4) , monopotassium phosphate (KH2PO4), dipotassium phosphate (K2HPO4), etc. Mixtures of the aforementioned salts can be particularly effective in facilitating the physical separation of red blood cells. For example, a mixture of disodium sulfate (Na2SO4) and monopotassium phosphate (KH2PO4) can be used.
    [32] In addition to binding agents, the bleaching composition can also alter the chemical structure of hemoglobin to change its color. Examples of such compositions are described in U.S. Patent Application Publication No. 20090062764 to MacDonald, et al., Which is also incorporated herein in its entirety. More particularly, the composition includes an oxidizing agent, which, in general, is capable of oxidizing hemoglobin or other substances responsible for an undesired color of the body exudates. Suitable oxidizing agents may include, for example, peroxygen bleaches (for example, hydrogen peroxide, percarbonates, persulfates, perborates, peroxyacids, alkyl hydroperoxides, peroxides, diacyl peroxides, ozonides, superoxides, oxoozonides and periodates); hydroperoxides (for example, tertbutyl hydroperoxide, cumila hydroperoxide, 2,4,4-trimethyl-pentyl-2-hydroperoxide, diisopropyl-benzene-monohydroperoxide, tert-amyl hydroperoxide and 2,5-dimethyl-hexane-2,5 dihydroperoxide); peroxides (for example, lithium peroxide, sodium peroxide, potassium peroxide, ammonium peroxide, calcium peroxide, rubidium peroxide, cesium peroxide, strontium peroxide, barium peroxide, magnesium peroxide, mercury peroxide, peroxide in
    Petition 870190099057, of 10/03/2019, p. 39/48 / 28 silver, zirconium peroxide, hafnium peroxide, titanium peroxide, phosphorus peroxide, sulfur peroxide, rhenium peroxide, iron peroxide, cobalt peroxide and nickel peroxide); perborates (for example, sodium perborate, potassium perborate and ammonium perborate); persulfates (for example, sodium persulfate, potassium dipersulfate and potassium persulfate); and so on. Other suitable oxidizing agents are omega 3 and 6 fatty acids, such as linoleic acid, α-linoleic acid, arachidonic acid, eicosapentaenoic acid, docosahexaenoic acid, eicosadienic acid, eicosatrienoic acid; etc.
    [33] Regardless of its shape, the bleaching composition can be applied to any liquid impermeable layer of the absorbent article, where it can come into contact with aqueous fluids exudated by the body (eg menstruation), such as the absorbent core 30, the top sheet 26, the assimilation layer 32, the transfer delay layer (not shown), and so on (see Figure 1). The bleaching composition can be applied continuously or discontinuously to some or all of a surface of a liquid-permeable layer (e.g., absorbent core, assimilation layer, transfer layer, etc.). In one embodiment, the bleaching composition may cover only a portion of the surface to ensure that the layer is still capable of retaining sufficient absorbent properties. For example, the bleaching composition may be present within the first peripheral zone 52, the second peripheral zone 54, the third peripheral zone 72 and / or the fourth peripheral zone 74 of the absorbent article 20 of Figure 1. In certain embodiments, it may be desired that the bleaching composition is positioned closer to the absorbent core 30, to minimize the risk of potential leakage. Therefore, in addition to, or in place of, the peripheral zones, the bleaching composition can also be positioned within the first transition zone 62 and / or the second transition zone.
    Petition 870190099057, of 10/03/2019, p. 40/48 / 28 transition 64. This can be accomplished by applying the bleaching composition to a surface that faces the body of the absorbent core 30 within the desired zones. Typically, however, it is desired that the inner area 80 be left substantially untreated with the bleaching composition, so that a user is able to monitor bodily exudations for infection or other health-related conditions.
    [34] In addition to being applied to the absorbent core 30, other configurations can also be employed in the present invention. For example, an additional layer (not shown) can be applied with the deodorant composition, which is in contact with the absorbent core 30. The additional layer can be formed from a variety of different porous materials, such as a perforated film , nonwoven weave (for example, cellulosic weave, spunhond weave, melthlown weave, etc.), foams, etc. In one embodiment, the additional layer may be in the form of a hollow shell (e.g., sachet, bag, etc.), which is folded, so that it partially or completely surrounds the absorbent core 30. The bleaching composition can be arranged inside this wrapper, so that it remains sealed in it before use. In another embodiment, however, the additional layer may be the assimilation layer
    32. Typically, the bleaching composition is arranged on a surface that faces away from the absorbent core 30; however, it should be understood that the bleaching composition can be positioned on any other surface, such as between the additional layer and the absorbent core 30.
    [35] Regardless of the particular modality employed, the printed patterns of the present invention are distributed in an asymmetrical manner around both the transverse and longitudinal center lines of the article, and are positioned at, or close to, the periphery of the article and extend across the least partially for portions of the surface that turns
    Petition 870190099057, of 10/03/2019, p. 41/48 / 28 for the body that overlaps the absorbent core. Such a carefully selected layout and design helps to visually mask the presence of body fluids or stains around the periphery of the article. The design of the patterns is also such that a majority of an interior area of the absorbent article is, in general, free of printed graphic objects, which helps the user to better detect the presence of body fluids during use and additionally intensifies the overall distinctive nature of the articles. The absorbent article may also contain an “active” masking component (for example, bleaching combination) in combination with unique patterns, to provide a synergistic impact on the user's overall experience with the product.
    [36] Although the invention has been read described in detail with respect to specific modalities of the same, it will be appreciated by the technicians in the subject, when reaching an understanding of the above, who can readily conceive changes to, variations of and equivalent to these modalities . Consequently, the scope of the present invention must be assessed as that of the appended claims and any of their equivalents.
