    FIELD OF THE INVENTION
    [001] The present invention relates to an absorbent article such as an incontinence absorbent or hygienic absorbent comprising an absorbent core that has an opening extending through it. BACKGROUND OF THE INVENTION
    [002] Absorbent articles of the type used in ordinary pants include intimate pads or pads for adult incontinence or female use.
    [003] Absorbents or pads are generally provided with an absorbent core to receive and retain body fluids. For these absorbent articles to work efficiently, the absorbent core must quickly acquire body fluids into the structure, from the point of application and subsequently distribute body fluids inside and throughout the absorbent core to provide maximum leakage containment. An acquisition / distribution layer in relation to the nucleus and an opening of the nucleus assist when subsequent insults are directed to the same location as previous insults, since the local area tends to be already saturated with liquid from the previous insult.
    [004] As these types of articles must be sized and configured to fit in the limited space available in the crotch portion of the underwear, a particular problem is that they may have leaks at the side edges, before the total absorption capacity of the article has been used. The liquid, instead of being absorbed, will flow through the top sheet and out along the side edges of the article, where it can escape out and dirty the user's clothing. Another disadvantage when the liquid flows outside the top sheet is that a large part of the top sheet in contact with the body will be wetted. This is, of course, highly undesirable, as it makes the article unhygienic and unpleasant to use.
    [005] Great efforts have been made in the past, in order to overcome the problem of lateral leakage in relation to absorbents and pillows for incontinence or female use. WO 2009067059 A1 discloses an absorbent article comprising an absorbent core having fold indications and a forming element in order to obtain the desired shape of the article. While state of the art models can alleviate the problem of side leaks, to a certain extent, there is still a great need to improve the safety of side leaks for the type of absorbent article that is used on the crotch portion of an underwear. DESCRIPTION OF THE INVENTION
    [006] It is an object of the present invention to provide an improved solution that alleviates the problem mentioned with the present articles.
    [007] The invention relates to an absorbent article according to claim 1. The absorbent article is an article such as an incontinence absorbent or hygienic absorbent with longitudinal and transverse side edges and end edges, which comprises a top sheet liquid permeable, a liquid impermeable back sheet and an absorbent core located between the top sheet and the back sheet. The absorbent core comprises a first absorbent layer that has an opening extending through it and a liquid flow control structure located between said first absorbent layer and said backsheet. The first absorbent layer has a longitudinal front portion and a longitudinal rear portion and a narrow transverse transition located between said front portion and said rear portion. The width of the narrow transverse passage is 50 to 75% of the widest transverse width of the front portion of the first absorbent layer and between 20 and 50% of the longitudinal length of the opening are located in the front portion of the first absorbent layer. In this way, an absorbent article is achieved which will remain in place during use and which will ensure that the liquid will be directed to the opening and pass to the liquid flow control structure and the core.
    [008] The width of the narrow transverse passage is preferably 55 to 70% of the widest transverse width of the front portion of the first absorbent layer, in order to obtain a good hook behind the user's tendons. The width of the narrow transverse passage can be 50 to 75%, preferably 55 to 70% of the widest transverse width of the rear portion of the first absorbent layer, in order to ensure a better fit of the article. The widest transverse width of the front and rear portions can be about 75 to 170 mm. The longitudinal length of the narrow transverse passage can be 5 to 20% of the longitudinal length of the first absorbent layer, to further ensure that the article has a good fit and remains in place during use. The width of the narrow transverse passage of the first absorbent layer may be less than 130 mm and greater than 30 mm, preferably less than 90 mm and greater than 50 mm, for a better fit of the article between the user's tendons. The longitudinal length of the first absorbent layer can be about 230 to 400 mm.
    [009] The front portion of the first absorbent layer may constitute 20 to 40% of the total longitudinal length of the first absorbent layer. An asymmetric shape of the resulting article from a shorter longitudinal length of the front portion of the first absorbent layer in relation to the rear portion further improves the fit and safety of the article against leakage.
    [010] The first absorbent layer has at least one opening that extends completely through the layer, thus forming a cavity in the article. 20 to 50%, preferably 20 to 40% of the longitudinal length of the opening can be located at the front of the first absorbent layer, in order to ensure proper positioning of the orifice in relation to the tendons of the article user. the longitudinal length of the opening in the first absorbent layer can be 10 to 60%, preferably 20 to 40% of the longitudinal length of the first absorbent layer, in order to guarantee the flow of liquid into the opening and not outside the sheet higher. The transverse dimension of the opening may be larger at the front portion of the first absorbent layer than the transverse dimension of the opening at the rear of the first absorbent layer, in order to improve the uptake of liquid through the orifice and beyond to the flow control structure of liquid. The first absorbent layer may have an opening only for leakage safety and to improve the feeling of safety for the user.
    [011] A second absorbent layer can be located between the liquid flow control structure and the backsheet, in order to further increase the absorption capacity of the article. The second absorbent layer may have a smaller surface area than the first absorbent layer, in order to improve the bowl shape of the article with increased capacity. The first absorbent layer may extend further back and forth in the absorbent article than the second absorbent layer. The article may comprise one or more additional absorbent layers.
    [012] The liquid flow control element is disposed between the first absorbent layer and the back sheet, but it can also be disposed between the first absorbent layer and a second absorbent layer. The first absorbent layer can be placed underneath and in direct contact with the top sheet, or alternatively it can be placed in indirect contact with the top sheet by means of one or more intervening components, such as tissue paper layers, acquisition layers or other absorbent layers. Likewise, the second absorbent layer can be placed directly under the liquid flow control element and in direct contact with the liquid flow control element and the backsheet, or it can be in indirect contact with one or both components through Intervening components. By arranging the liquid flow control element between the first and second absorbent layers, this forms a channel in the absorbent article and conducts the liquid to and fro the article. The contact area between the liquid flow control element and the absorbent core increases, which facilitates the distribution and rapid absorption of liquid in the article.
    [013] The absorbent article is in the form of an incontinence pad, or a sanitary pad, and can be used for women or for incontinence, and can have an elongated shape, usually rectangular when fully extended in all directions. In this context, a generally rectangular shape is also intended to encompass that, for example, the corners of the absorbent article may be rounded, or that the edges of the absorbent article may not be completely linear. The absorbent article may have two longitudinal side edges of equal length and which generally extend in the same direction.
    [014] The top sheet and the back sheet of the absorbent article can extend laterally together outside the first absorbent layer along the entire circumference of the article and be connected together by means of an edge joint around the periphery of the core absorbent for safety against leaks. The topsheet may preferably cover a portion of the backsheet to form an end barrier.
    [015] The top sheet may consist of any material that is suitable for the purpose, that is, it is permeable to liquid and soft. Examples of top sheet materials are non-woven materials, perforated plastic films, textile or plastic mesh and layers of liquid-permeable foam. Laminates made up of two or more top sheet materials can also be used, as well as liquid-permeable topsheets consisting of different materials on different parts of the user facing surface.
    [016] The backing sheet is impermeable to liquid. However, backsheet materials that are only liquid repellent can be used particularly in cases where relatively small amounts of urine must be collected. The backsheet may be a thin, flexible liquid-impermeable plastic film, such as polyethylene or polypropylene, but liquid-impermeable non-woven materials, liquid-impermeable foams and liquid-impermeable laminates are also contemplated within the scope of the invention. . The backsheet can preferably be breathable, which implies that air and steam can pass through the backsheet. In addition, the backsheet may have an outer clothing-facing surface made of a textile material, such as non-woven.
    [017] The absorbent core comprises a first absorbent layer. It may comprise only one absorbent layer, but it may comprise a second or more absorbent layers. The absorbent core can be made of any suitable absorbent or liquid-trapping material, such as one or more layers of cellulose fluff pulp, foam, hiqhloft, etc. The absorbent core can contain fibers or particles of highly polymeric material absorbents, commonly known as superabsorbents, which are materials that have the ability to absorb and retain large amounts of liquid by forming a hydrogel. Superabsorbent materials can be mixed with the pulp of cellulose fluff and / or can be arranged in layers or bags in the absorbent core. The fibers may be cellulose fibers and the superabsorbent material may be based on polyacrylate particles. The absorbent structure can comprise 40 to 80% superabsorbents and 60 to 20% cellulose fibers. The absorbent core may further incorporate components to improve the properties of the absorbent core. Some examples of such components are binder fibers, liquid dispersion materials, wetting indicators, liquid acquisition materials, etc.
    [018] The absorbent layers may be homogeneous structures or may themselves be layered structures, such as absorbent laminates of the same or different materials. The absorbent layers may be of uniform thickness or may vary in thickness in different parts of the layers. Likewise, the base weight and composition can vary within the absorbent layers. For example, an absorbent layer may comprise a mixture of absorbent and / or non-absorbent fibers and superabsorbent material, the proportion of superabsorbent material in relation to the fibers may vary in the layer. One or more compressed lines, acting as hinges, can advantageously be arranged on the first absorbent layer, which can be relatively rigid, to facilitate folding the absorbent article.
    [019] The topsheet preferably extends into the cavity that is defined by the opening in the first absorbent layer and the surface of the liquid flow control structure that faces the topsheet. In this way, the cavity will be lined with the material of the top sheet and will be accessible from the outer surface facing the body of the absorbent article. A portion of the liquid that is collected in the cavity can be absorbed by the first absorbent layer through the walls of the cavity. However, most of the liquid will continue downwards in the absorbent article, through the bottom of the cavity and the liquid flow control element where it will be distributed longitudinally and laterally along the flow control element.
    [020] The liquid flow control element can be rectangular in shape and can be surrounded in longitudinal and lateral directions by portions of the absorbent core. It is also possible to use other shapes and configurations for the liquid flow control structure. However, it is generally advantageous for the liquid flow control element to be smaller in width and shorter than the absorbent core, as this facilitates distribution to a large area of the absorbent core.
    [021] Elastic elements can be arranged along each longitudinal side edge of the sanitary pad, at least laterally outside the narrow transitional transition between the front portion and the rear portion of the first absorbent layer, to further improve the shape of the article. The elastic elements are preferably located between the topsheet and the backsheet. The absorbent article preferably has an intermediate space, located along each side edge of the first absorbent layer, which is substantially free of absorbent material, in order to obtain an elegant shape and better adaptation of the article to the user. The intermediate space can be located adjacent to the narrow transverse transition of the first absorbent layer in an area between the elastics, located on the periphery of the product, and on the periphery of the first absorbent layer.
    [022] The absorbent article may also include fastening means for fixing the absorbent article within a garment such as support pants, such as a pair of pants. The fixing means can be covered by a detachable protective layer. BRIEF DESCRIPTION OF THE DRAWINGS

    [030] The invention will be described in more detail below by way of an exemplary embodiment. The invention, however, can be realized in many different ways and should not be interpreted as limited to the embodiments shown in the Figures and their description.
    [031] Figure 3 schematically describes an absorbent article (1) in the form of an incontinence pad seen from the side that is intended to face the body of a user when the article is in use. The article (1) has two longitudinal lateral edges (2), (3) of equal length and which generally extend in the same direction. Front and rear end edges (4), (5) extend across the ends of the article (1). The rear end edge (5) is intended to be oriented backwards when using the article (1), and the front end edge (4) is intended for the star facing forward towards the user's abdomen. The article (1) comprises a liquid-permeable top sheet (8), a liquid-impermeable back sheet (9) and an absorbent core (10) that has a first absorbent layer (11) and a liquid flow control structure (13), placed between the top sheet (8) and the back sheet (9) as seen in Figure 4. The core in Figures 3 to 5 comprises a second absorbent layer (15) located between the flow control structure liquid (13) and the backsheet (9). The top sheet (8) and the back sheet (9) of the article (1) are shown extending together laterally out of the first absorbent layer (11) along the entire circumference and connected to each other at a joining edge around the periphery of the article (1). The joining edge can be formed in any suitable manner, as known in the art, such as by means of an adhesive, ultrasonic welding, thermal bonding, stitching, etc. The top sheet (8) and the back sheet (9) can consist of any suitable material, such as a non-woven material or film, for the specific purpose, as disclosed herein.
    [032] The elastic elements (16), such as bands of elastic material, for example, foam elastics, are placed between the top sheet and the back sheet (8) and (9), along the longitudinal side edges of the first absorbent layer (1). The elastics are located in the area outside the narrow transitional transition (14), which is located between the front portion (6) and the rear portion (8) of the first absorbent layer (11). An intermediate space (17) is located in an area between the elastic element (16) and the narrow transverse transition (14), that is, laterally outside the narrow transverse transition of the first absorbent layer (11). The intermediate space (17) is substantially free of absorbent material. The intermediate space provides an elegant shape of the article and improves the fit of the article on the user which leads to a reduction in lateral leakage.
    [033] Figures 1 and 2 show a first absorbent layer (11) that has an opening (12) that extends through it. The liquid flow control structure (13) is located under the first absorbent layer (11). The first absorbent layer (11) has a longitudinal front portion (6) and a longitudinal rear portion (7) and a narrow transverse transition (14) located between the front portion (6) and the rear portion (7) as seen in Figure 1. The width of the narrow transverse transition (14) is 50 to 75% of the widest transverse width of the front portion (6) of the first absorbent layer (11) and 50 to 75% of the widest transverse width of the rear portion (7 ) of the first absorbent layer, for example, 65 mm. The widest transverse width of the front portion (6) and the rear portion (7) can be about 75 to 170 mm, such as 100 mm. The longitudinal extension of the narrow transverse transition (14) is 5 to 20% of the longitudinal length of the first absorbent layer (11). The front portion of the first absorbent layer is 20 to 40% of the longitudinal length of the first absorbent layer. The longitudinal length of the first absorbent layer (11) can be about 230 to 400 mm, for example, 300 mm.
    [034] The absorbent article (1), as shown in Figure 3, has an elongated shape, usually rectangular when fully extended in all directions. The word "generally" in this context means that, for example, the corners of the incontinence protector (1) may be rounded, or the edges of the incontinence protector (1) may not be completely linear.
    [035] The absorbent article (1) may also have fixing means (not shown in the Figures) for fixing the article (1) inside a garment like support pants, such as a pair of pants. The fixing means can be in the form of two longitudinally extending strips of pressure sensitive adhesive, arranged on the surface of the back sheet (9) facing the laundry. The fixing means can be covered by a detachable protective layer. The protective layer can be a silicone paper, a nonwoven or any other release material as is known in the art. Before placing the incontinence protector on the support pants, the protective layer is removed from the fixation means to expose the adhesive and make it available to attach to the pants.
    [036] The fixation means is optional for the invention and can be omitted, if desired. When using an adhesive fastening means, any suitable adhesive pattern can be used, such as complete backing coating, one or more bands of longitudinal adhesive, transversal bands, points, circles, curves, stars, etc. In addition , the fastening means can be a mechanical fastener, such as hook fastener, clamps, push buttons, etc., or it can be a friction fastener, such as a friction coating or open cell foam. Combinations of different types of fasteners are also conceivable.
    [037] The absorbent core (10) of the absorbent article (1) shown in Figure 3 comprises a first absorbent layer (11) and a second absorbent layer (15). The absorbent layers may comprise a mixture of absorbent and / or non-absorbent fibers and superabsorbent material. The liquid flow control structure (13) is arranged between the first absorbent layer (11) and the second absorbent layer (15). In the absorbent article (1) in Figure 3, the first absorbent layer (11) is placed underneath and in direct contact with the top sheet (8).
    [038] The second absorbent layer (15) is shown to be generally rectangular in shape. The second absorbent layer (15) is placed under the first absorbent layer (11). The second absorbent layer (15) is slightly smaller than the first absorbent layer (11), so that the first absorbent layer (11) extends beyond the second absorbent layer (15) back and forth in the article absorbent (1). The size and shape of the absorbent layers may be different from those shown in the Figures, without departing from the invention. In addition, the second absorbent layer (15) can be omitted in the absorbent article (1) according to the invention or the article (1) can comprise one or more additional absorbent layers.
    [039] The first absorbent layer (11) has an opening (12) that extends completely through the first absorbent layer (11). The absorbent layer (11) can have one or more openings (12) of different shapes and configurations. An elongated opening (12) is, however, preferred. The longitudinal length of the opening (12) is 10 to 60% of the longitudinal length of the first absorbent layer. The length of the opening can be, for example, about 100 mm. The opening (12) is located 20 to 50% of its longitudinal length in the front portion (6) of the first absorbent layer (11). The transverse dimension of the opening (12) is greater in the front portion (6) of the first absorbent layer (11), than the transverse dimension of the opening (12) in the rear portion (7) of the first absorbent layer (11). The opening (12), when the article is in use, will be placed directly under the urethra and vaginal opening of a female user. Any body liquid that is released into the absorbent article (1) will be collected directly into the opening (12) and be temporarily contained therein until it is further distributed into and across the absorbent core (10).
    [040] In Figure 4, the top sheet (8) does not extend downward into the cavity that is defined by the opening (12) in the first absorbent layer (11) and the surface of the liquid flow control structure (13 ) facing the top sheet, but you can preferably do so. A portion of the liquid that is collected in the opening (12) can be absorbed by the first absorbent layer through the walls of the first absorbent layer in the opening (12). However, most of the liquid will continue down the absorbent article (1) and into the liquid flow control structure (13), where it is distributed longitudinally and laterally along the flow control structure (13).
    [041] The liquid flow control structure (13) is shown in Figures 1 to 5 as having a rectangular shape and being surrounded in the longitudinal and lateral directions by parts of the absorbent layers (11), (15). In general, it is advantageous that the liquid flow control structure (13) is smaller in width and preferably also shorter than the absorbent layers (11), (15).
    [042] The liquid flow control structure (13) can be a three-layer structure consisting of a perforated non-polymeric fibrous layer that is sandwiched between a first perforated polymeric layer and a perforated second polymeric layer.
    [043] The components of the absorbent article (1) can be bonded together by conventional means, such as construction adhesive, hot bond, ultrasonic bond, etc. It may not be necessary to bond the internal components of the incontinence protector between by special means of connection. Thus, it may be sufficient that these components are held together by frictional forces.
    [044] Figure 6 is a side elevation view of an exemplary embodiment of an article according to the invention. The narrow transverse transition (14) between the front portion (6) and the rear portion (7) of the first absorbent layer provides a better fit of the article to the user and is reinforced by the intermediate space (17) and the elastic elements (16) .
