    [0001] FIELD OF THE INVENTION The present application relates to absorbent articles, including catamenial devices, such as sanitary napkins, for the absorption of rulers. More particularly, the present invention relates to catamenial devices comprising one or more graphic images in which the graphic images outline the functional area of the absorbent article.
    [0002] BACKGROUND OF THE INVENTION Disposable absorbent articles, such as sanitary napkins, diapers, incontinence products in adults, and catamenial tampons are manufactured at high speed. However, today's high-speed modern production lines exhibit inherent variation in cross-web (CD) lay-up and the combination of webs. If it is perceived by the consumer, this variation in the cross direction can impact the perception of quality of the product. For example, a consumer may think that a product will not work properly if he notices that the absorbent core is not centrally located between the fin components of the article. In addition, consumers appreciate the color. Color is often added in the form of graphics or single-layer graphics in the product. The printing of graphic elements on the upper layer of the article may communicate a barrier signal or highlight the functional area of the product. However, graphic elements of printed products, of the barrier signal type to highlight the functional area of the product, which are preferred by the consumers, may actually enhance the perception of cross-directional variation encountered in current products, reminiscent of consumers that the item is defective, when in fact the product still meets the quality standards to function properly. To address this problem, current products either sacrifice efficient barrier signal graphics or are forced to incur significant costs to slow down the chains or purchase specialized equipment to reduce cross-machine variation. These costs can be prohibitive.
    [0003] For example, the current products are printed far away from the perimeter of the core so that the perception of placement of the core will be more acceptable for the large variation in cross-direction. Graphic elements were also placed on the entire backsheet prior to core placement so as not to be affected by cross-directional variation. Finally, graphical elements have been asymmetrically placed in areas outside the core perimeter to avoid processing cross-directional variation. As such, what is required is a specific graphical orientation printed on the topsheet of an article, which gives a consumer an acceptable signal and is likely to be created in a high speed manufacturing process. . SUMMARY OF THE INVENTION An object of the invention is an absorbent article which comprises: a liquid-permeable topsheet, the topsheet having an inwardly facing inner surface of the absorbent article and an outer surface oriented towards the skin of the wearer when the absorbent article is worn; a backsheet joined to the topsheet, the backsheet having an inner surface facing inwardly of the absorbent article and an outer surface facing the wearer's garment as the absorbent article is worn; An absorbent core having a perimeter, disposed between the topsheet and the backsheet, the absorbent core having an inner surface oriented toward 1. carrier skin when the absorbent article is worn and an outer surface facing the wearer's garment when the absorbent article is worn; wherein the topsheet comprises four or more graphic elements; and wherein the graphical elements overlap the perimeter of the absorbent core such that the core perimeter has an ink zone-to-blank ratio of between 5% and 60%. In addition, the absorbent article of the present invention may include adjacent graphical elements that do not touch each other.
    [0004] In addition, the absorbent article of the present invention may be an absorbent article in which no set of two adjacent graphical elements within a quadrant share a longitudinal center line that is parallel to the longitudinal axis. In addition, the absorbent article of the present invention may be divided into quadrants by a longitudinal axis and a transverse axis and wherein at least one graphic element is located in each quadrant. In addition, the absorbent article of the present invention may comprise an absorbent core that has a perimeter divided into octants and wherein at least one graphic element is located in each octant.
    [0005] In addition, the absorbent article of the present invention may include graphical elements that overlap the absorbent core perimeter so that the perimeter line bisects one or more graphical elements. In addition, the absorbent article of the present invention may comprise graphic elements that have a width of between 0.1 cm and 12 cm.
    [0006] In addition, the absorbent article of the present invention may include graphic elements that are printed on a garment-facing side of the topsheet. In addition, the absorbent article of the present invention may include a functional layer signal that is located within the absorbent core perimeter. In addition, the absorbent article of the present invention may comprise a functional layer signal which is selected from the group consisting of a graphic element and a structural identifier. BRIEF DESCRIPTION OF THE DRAWINGS While the description ends with claims particularly emphasizing and distinctly claiming the subject of the present invention, it is believed that the invention will be more readily understood from the following description taken in conjunction with the accompanying drawings. Figure 1 is a top view of a representative catamenial device. Figure 2 is a product graphics scheduling as described.
    [0007] Figures 3A-C show a product graphics scheduling as described.
    [0008] Figures 4 to 7 show product graphics schedules within the scope of the invention. DETAILED DESCRIPTION OF THE INVENTION The present invention relates to printed product graphics and absorbent articles, particularly disposable absorbent articles, having one or more graphics visible from the body-facing side of the topsheet. The scheduling of product graphics allows high-speed manufacturing while highlighting the functional area of the article. Disposable absorbent articles may be feminine hygiene articles, including incontinence devices and catamenials, such as, sanitary napkins, pantiliners, interlabial products, and the like. For convenience, the invention is described below with respect to the embodiment of a catamenial device, such as a sanitary napkin or a pantiliner.
    [0009] The absorbent article of the present invention comprises a liquid pervious topsheet, a bottom sheet attached to the topsheet, and an absorbent core having a perimeter disposed between the topsheet and the backsheet. The topsheet has an inner surface facing inwardly of the absorbent article or garment facing side and an outer surface facing the wearer's skin when the absorbent article is worn or the body facing side. The backsheet has an inwardly facing inner surface of the absorbent article and an outer surface facing the wearer's garment as the absorbent article is worn. The absorbent core has an inner surface facing the wearer's skin when the absorbent article is worn and an outer surface facing the wearer's garment as the absorbent article is worn. The topsheet includes four or more graphic elements. The graphics overlap the perimeter of the absorbent core such that the core perimeter has an ink zone ratio on a blank area of between 5% and 60%. As used herein, "percentage of visible ink area on virgin area" refers to the percentage of the absorbent core perimeter that is overlapped by a graphic. The percentage of visible ink area on virgin area can be calculated by measuring the absorbent core perimeter, by measuring the portions of any graphical elements that overlap the absorbent core perimeter along the perimeter of the web. Absorbent core, by adding the total length of the absorbent core perimeter which is overlapped by graphics, and dividing the sum of the absorbent core perimeter which is overlapped by graphic elements by the total absorbent core perimeter.
    [0010] As used herein, a "functional layer signal" refers to any identifier that draws attention to the functional absorbent portions of the absorbent article. The functional layer signal may be a structural identifier such as, for example, openings in the form of notches or dots in or around the functional layer, graphic elements on or around the viewing portion of the functional layer. of the functional layer, or a combination of structural elements and graphic elements that direct a user to the functional layer of the absorbent article. As used herein, a "printed graphic orientation" refers to a set of graphic elements within a given area. However, as mentioned, the graphic elements need not necessarily be printed on the same surface within this area. As used herein, a "product graphics scheduling" refers to the combination of graphical elements visible from the body surface of the absorbent article. The scheduling of product graphics may have four or more graphics elements. The scheduling of product graphics may be a functional layer signal. Regardless of the particular configuration of the layers used to form the absorbent article, a plurality of graphic elements are printed in a product graphics schedule so that they are visible from the body facing surface. The particular graphic elements are chosen to provide a unique visual appearance that highlights the functional area to the consumer while allowing high speed manufacture of the absorbent article. High speed manufacturing is accomplished by placing a layer of material on top of another layer until the article is completed. Each layer of material should be placed within a calculated margin of error. Otherwise, the manufacturing system may find the product unacceptable. Although a product may be acceptable because of manufacturing recommendations, it is possible to have a sanitary napkin in which the absorbent core has shifted in the cross direction along the transverse axis. The inventors have found that by placing graphic elements in a single printed graphic orientation, the sanitary napkin can have consumer-acceptable graphics that highlight the functional area while enabling high-speed manufacturing.
    [0011] Figure 1 shows a sanitary napkin 10, for example, having a body-contacting surface 12 comprising an outer surface of a topsheet 14, a liquid impervious backsheet 16 joined to the topsheet 14, and an absorbent core 18. The sanitary napkin 10 has a longitudinal axis L, a transverse axis T. The longitudinal axis and the transverse axis meet at a central point of the sanitary napkin. The longitudinal axis and the transverse axis divide the sanitary napkin into four quadrants 101, 102, 103, 104. The absorbent core has a perimeter. The absorbent core perimeter of the absorbent core 20 can be divided into octants. An octant is calculated by measuring the length of the absorbent core perimeter and dividing the total length by eight. As illustrated in FIG. 2, each octant contains an equal length of the absorbent core perimeter 201, 202, 203, 204, 205, 206, 207 and 208. Each quadrant contains a portion of the absorbent core including the perimeter of the absorbent core. absorbent soul. Graphic elements 26 may be printed on the body facing surface or the garment facing surface of the topsheet so that they are easily visible. Additional graphic elements 26 may be printed on any layer of the absorbent article 10. The additional graphic elements 26 may be printed on the body-facing side of the backsheet 16, on the side facing the body of a secondary topsheet (not shown), on a side facing the body of an absorbent core 18, or on a portion of a side facing the body of the absorbent core 18.
    [0012] The graphic elements may have different sizes, colors, shapes and designs. Graphical elements can be balanced to the extent that several smaller graphic elements on one side can be "balanced" by a large graphic element on the other side, or smaller objects can be placed further away from the center than larger objects. Alternatively, a darker object can be balanced in the same way by several lighter objects. It should also be noted that although graphical elements 28 and 34 are shown here as having relatively simple shapes, this is for illustrative purposes only. So to speak any shape or any design can be used, such as points, ovals, triangles, squares, rectangles, flowers, butterflies, stars, hearts, spirals , double spirals, clothoid curves, Cornu spirals, polynomial double spirals, Euler double spirals, parametric double spirals, and so on. In fact, it is generally preferable that the graphic elements be of a more complicated nature and that they have a certain degree of curvature and color to provide a more complex visual perception and participate in the overall masking effect of the article. . For example, Figures 4 to 7 generically illustrate more complex graphical elements that may be employed in the present invention.
    [0013] In some cases, the graphic elements may also be arranged to communicate an optical illusion when viewed from a particular focal point of the user. For example, arranging the graphical elements relative to one another can form a perceptible optical illusion of movement as at least one of the objects seeming to move away from an edge of the body. Exemplary objects for providing such an illusion pattern may include a geometric shape, a spiral, an abnormal movement, a form of rotation, a color change, a peripheral drift, positive blurs after the image, a scintillation grid, stereoscopic and chromostereoscopic vision, contraction and expansion, contrast polarities, convection, chromatic assimilation, etc., as described in US Patent Publication Nos. 2009/0157021 to Sullivan, et al. and 2005/0268371 of Meekins. In many embodiments, graphical elements of different shades may be employed to create a perception of depth within the absorbent article by a user observing the viewing surface of the absorbent article. Such illusion patterns are described in U.S. Patent Publication No. 2003/0114811 to Christen, et al. The printed graphic orientation highlights the absorbent core or functional area of the article while providing flexibility during high speed manufacturing. The inventors have found that by balancing the location of the graphics, placing a size limitation on the graphics, and placing graphics along the absorbent core perimeter to have a percentage of ink area Visible on 5% to 60% virgin area along the web perimeter, product graphics orientation can be achieved which allows for high speed manufacturing while being acceptable to the consumer.
    [0014] In many embodiments, the functional zone may have an additional functional indicator within the perimeter of the absorbent core. The additional functional indicator may be one or more additional graphic elements, openings, perforations, notches, or points in the core. The additional functional indicator may be located beneath the topsheet, in or on the absorbent core, or any other layer that is visible from the body-facing surface of the topsheet. As illustrated in FIGS. 2 and 3A-C, the inventors have found that graphic elements can be placed to satisfy consumer acceptability while allowing high speed manufacturing and highlighting the functional area of the article. absorbent. Without being limited to a particular theory, the inventors have found that the objectives are achieved by following a recommended criterion for the overall scheduling of product graphics. Figures 2 and 3A-C show product graphics schedules on an absorbent article 10. The absorbent article 10 has a topsheet 14, a backsheet 16, a body-facing surface 12, and a web Absorbent 18. The product graphics orderings comprise four or more graphics elements 26. The absorbent article 10 is divided into quadrants 101, 102, 103, 104 by the longitudinal axis and the transverse axis. The absorbent core perimeter 20 is divided into 20 octants 201, 202, 203, 204, 205, 206, 207 and 208. As illustrated in FIGS. 2 and 3A-C, the functional zone contains additional functional layer signals under In the form of notches 30 and dots 32. As shown in FIGS. 2 and 3A-C, adjacent graphic elements 26 do not come into contact or overlap. As illustrated in FIGS. 2 and 3A-C, no set of two adjacent graphical elements within a quadrant share a longitudinal centerline parallel to the longitudinal axis. As illustrated in Figures 2 and 3A-C, at least one graphic is located in each quadrant. As shown in Figures 2 and 3A-C, at least one graphic is located in each of the eight octants. In many embodiments, the graphic elements along the absorbent core perimeter can not be along the same line. For example, graphic elements should not form a straight line. Graphics should not touch or describe a continuous frame around the absorbent core perimeter.
    [0015] In many embodiments, the graphic elements are spaced such that there is between 1 mm and 30 mm between each graphic, such as, for example, between 2 mm and 15 mm, between 5 mm and 10 mm. mm, such as, for example, 3 mm, 4 mm, 6 mm, 7 mm, 8 mm or 9 mm. The distance between the graphic elements may vary. For example, the distance between a first graphic element and a second graphic element may be 3 mm while the distance between the first graphic element and a third graphic element may be 2.2 mm. As illustrated in FIG. 2, the absorbent core 18 can be divided into quadrants 101, 102, 103 and 104.
    [0016] The graphic elements 26 can be balanced by placing graphic elements 26 around the perimeter 20 of the absorbent core 18 so that the percentage of ink zone along the absorbent core perimeter is between 5% and 60% between 10% and 50%, such as, for example, 15%, 20%, 25%, 30%, 35%, 40%, 45% or 50%. As illustrated in Figure 2, the percentage of visible ink area on virgin area for the perimeter is about 60%. The graphic elements 26 may be placed in each quadrant provided that they are within the required size restriction limits of less than 12 cm wide along the cross direction. In many embodiments, the size of the graphics varies. Graphic elements along the web perimeter shall be between 0.1 cm and 12 cm wide. This range provides the acceptable range for core placement in the cross direction. As illustrated in FIGS. 3A-C, the absorbent article 10 has a plurality of graphic elements 26. The graphic elements 26 can be balanced by placing graphic elements 26 around the perimeter 20 of the absorbent core 18 so that the percentage of area visible ink on blank zone for perimeter is between 5% 25 and 60%, between 10% and 50%, such as, for example, 15%, 20%, 25%, 30%, 35%, 40% , 45% or 50%. As illustrated in FIGS. 3A to C, the scheduling of product graphics can be between 0 and 6 cm in relation to the longitudinal centerline while still highlighting the absorbent core 18 of the article. Absorbent 10. As illustrated in Figure 3A, product graphics scheduling may be centered on the longitudinal axis and the transverse axis. As shown in Figure 3B, the product graphics scheduling shifted in both the cross machine direction and the machine direction. Also, as illustrated in Figure 3C, the product graphics scheduling has shifted both in the cross machine direction and in the machine direction. The graphic elements 26 can be placed in each octant provided that they are within the required size restriction limits of between 0.1 cm and 12 cm in width. In many embodiments, the size of the graphics varies. It is not required that each octant include a graphic 26 to highlight the absorbent core 18. A graphic 26 may overlap the octants. The sanitary napkin may also be provided with additional features commonly found in towels, including "wings" or "flaps" as known in the art, and / or a secondary topsheet, and / or a collection layer. of fluid, and / or other layers designed to promote fluid transport to the absorbent core 18. Similarly, the topsheet 14 of the sanitary napkin may have various optional features, as is known in the art. . For example, the topsheet 14 may include one or more embossed channels for directing fluid flow, apertures therethrough to facilitate fluid collection, and printed signals visible on or across the signals. visible being printed on the topsheet or underlying layers for functional and aesthetic properties. The topsheet can be made from a wide range of materials such as woven and nonwoven materials; polymeric materials such as perforated shaped thermoplastic films, perforated plastic films, hydroformed thermoplastic films; porous foams; crosslinked foams; crosslinked thermoplastic films; and thermoplastic muslin. Suitable woven and nonwoven materials may include natural fibers (e.g., wood or cotton fibers), synthetic fibers (e.g., polymeric fibers such as polyester, polypropylene or polyethylene fibers) or combination of natural and synthetic fibers.
    [0017] In many embodiments, the topsheet may be made of a hydrophobic material to isolate the wearer's skin from liquids that have passed through the topsheet. If the topsheet is made of a hydrophobic material, at least the upper surface of the topsheet is treated to be hydrophilic so that the liquids migrate more quickly through the topsheet. This reduces the likelihood that body exudates will flow out of the topsheet rather than being drawn through the topsheet and absorbed by the absorbent core. In many embodiments, the topsheet can be made hydrophilic by treating it with a surfactant. Suitable methods for treating the cover sheet with a surfactant include spraying the cover sheet material with the surfactant and immersing the material in the surfactant. The topsheet may include a perforated shaped film. Perforated shaped films may be used for the topsheet because they are permeable to body exudates while being non-absorbent and have a reduced tendency to allow liquids to re-flow and rewet the wearer's skin. Thus, the surface of the formed film that is in contact with the body remains dry, thereby reducing body soiling and creating a more comfortable feeling for the wearer. Suitable formed films are described in U.S. Patent No. 3,929,135, entitled "Absorptive Structures Having Tapered Capillaries", issued to Thompson on December 30, 1975; U.S. Patent No. 4,324,246 entitled "Disposable. Absorbent Article Having A Stain Resistant Topsheet, issued to Mullane, et al. April 13, 1982; U.S. Patent No. 4,342,314 entitled "Resilient Plastic Web Exhibiting Fiber-like Properties", issued to Radel, et al. August 3, 1982; U.S. Patent No. 4,463,045 entitled "Macroscopically Expanded Three-Dimensional Plastic Web Exhibiting Non-Glossy Visible Surface and Cloth-Like Tactile Printing", issued to Ahr, et al. July 31, 1984; and U.S. Patent No. 5,006,394 "Multilayer Polymeric Film" issued to Baird on April 9, 1991. The absorbent core may be any absorbent element that is generally compressible, flexible, non-irritating to the wearer's skin, and which is capable of absorbing and retaining body fluids. The absorbent core can be manufactured in a wide variety of sizes and shapes (e.g., rectangular, hourglass, T, asymmetric, etc.), and from a wide variety of liquid-absorbing materials commonly used in disposable pull-on garments and other absorbent articles, such as ground wood pulp which is generally referred to as airy felt. Examples of other suitable absorbent materials include creped cellulose wadding; melt blown polymers, including coformed polymers; chemically stiffened modified or crosslinked cellulose fibers; absorbent paper including absorbent paper wraps and absorbent paper laminates; absorbent foams; absorbent sponges; superabsorbent polymers; absorbent and gelling materials; or any equivalent material or any combination of materials. The configuration and construction of the absorbent core may vary (for example, the absorbent core may have areas of varying thickness, a hydrophilic gradient, a superabsorbent gradient, or a lower average density, and collection at lower average surface mass, or may include one or more layers or structures). In addition, the size and absorbency of the absorbent core can also vary to accommodate carriers ranging from infants to adults. The total absorbent capacity of the absorbent core should, however, be consistent with the intended load and the intended use of the absorbent article. The absorbent core may include other optional components. An optional component such is the core shell, i.e., a material, typically, but not always, a nonwoven material, which surrounds or partially or completely the core. Suitable core wrapping materials include, but are not limited to, cellulose, hydrophilic nonwoven materials, perforated films, and combinations thereof. The backsheet may include a liquid impervious film. The backsheet may be impervious to liquids (e.g., body fluids) and may typically be manufactured from a thin plastic film. However, typically the backsheet may allow the vapors to escape from the disposable article. In many embodiments, a microporous polyethylene film may be used for the backsheet. A suitable microporous polyethylene film is manufactured by Mitsui Toatsu Chemicals, Inc., Nagoya, Japan and marketed as PG-P. A suitable material for the backsheet may be a liquid impermeable thermoplastic film having a thickness of from about 0.012 mm (0.50 mil) to about 0.051 mm (2.0 mils), including, for example, polyethylene or polypropylene. Typically, the backsheet may have a basis weight of from about 5 g / m 2 to about 35 g / m 2. However, it should be noted that other flexible liquid impervious materials can be used as a backsheet. Here, the term "flexible" refers to materials that are adaptable and will readily assume the general shape and general contours of the wearer's body. The backsheet may typically be placed contiguously to the outwardly facing surface of the absorbent core and may be joined thereto by any fastener known in the art. For example, the backsheet may be attached to the absorbent core by a continuous uniform layer of adhesive, an adhesive pattern layer, or a network of separate lines, spirals, or dots of adhesive. Adhesives given by way of example, but not limited to, include adhesives manufactured by H. B. Fuller Company of St. Paul, MN, USA, and marketed as HL-1358J. An example of a suitable fastening device including an open pattern network of adhesive filaments is disclosed in US Patent No. 4,573,986 entitled "Disposable Waste-Containment Garment", which was issued to Minetola et al. . on March 3, 1986. Another suitable fastener including several lines of adhesive filaments wound in a spiral pattern is illustrated by the apparatus and methods shown in US Patent No. 3,911,173 issued to Sprague, Jr. on May 7, 1986. October 5, 1975; U.S. Patent No. 4,785,996 issued to Ziecker, et al. November 22, 1978; and U.S. Patent No. 4,842,666 issued to Werenicz on June 27, 1989. Alternatively, the fastener may include thermal bonds, pressure bonds, ultrasonic bonds, dynamic mechanical bonds, or any other suitable fastening device or combinations of these fasteners.
    [0018] The backsheet may further be affixed to the topsheet by any of the fasteners mentioned above. The dimensions and values described here should not be understood as strictly limited to the exact numerical values quoted. Instead, and unless otherwise indicated, each of these dimensions corresponds both to the indicated value and to an equivalent functional range around that value. For example, a dimension described as "40 mm" means "about 40 mm". The values described here as range thresholds should not be understood as strictly limited to the exact numerical values cited. Rather, unless otherwise specified, each numeric range means both the cited values and any integers in the range. For example, a range described as "1 to 10" means "1, 2, 3, 4, 5, 6, 7, 8, 9, 10". The citation of any document should not be construed as an admission that the document pertains to a prior art in relation to the present invention. To the extent that any meaning or definition of a term in this document conflicts with any meaning or definition of the same term in any other document, the meaning or definition attributed to that term in this document shall prevail . While particular embodiments of the present invention have been illustrated and described, it would be apparent to those skilled in the art that various other changes and modifications may be made without departing from the spirit and scope of the invention. . It is therefore intended to cover in the appended claims all those variations and modifications which fall within the scope of the present invention.
