The present disclosure is directed to configurable absorbent articles having removable fastening members.
Absorbent articles are used to contain bodily exudates (e.g., urine and BM) in infants, children, and adults. Absorbent articles may be used in hospitals for diapering infants, premature babies, and/or Neonatal Abstinence Syndrome (“NAS”) babies. Premature babies, NAS babies, or other small infants may require special care by nurses and other hospital staff. These babies are oftentimes on ventilators, feeding tubes, or other life support or monitoring systems. In some instances, the babies may be positioned within incubators, also known as isolettes. The babies are typically kept in high humidity, sterile environments as they have very delicate skin that needs to be protected. It is important to the health of these premature babies that they not be handled too much and that they are maintained in a very sterile environment. Handling the babies too much may cause them stress. Current absorbent articles for premature or NAS babies are somewhat difficult to use and too large for very premature babies, especially in the crotch region. When the current absorbent articles are folded about their lateral axis, they typically take on a rectangular or substantially rectangular shape, thereby providing a wide crotch region. Additionally, current absorbent articles for premature and NAS babies do not provide superior containment of bodily exudates and skin protection from the bodily exudates. Furthermore, current absorbent articles do not provide full flexibility with fastener systems. Premature or NAS babies may benefit from unconventional fastening system requirements. Further, the current absorbent articles do not provide all of the features that premature or NAS baby caregivers may view as beneficial. As such, absorbent articles for premature babies, NAS babies, other babies, and other wearers need to be improved.
The present disclosure provides configurable absorbent articles suitable for premature and NAS babies (and other small infants, other babies, or other wearers), while not being limited to any certain sizes or uses. As discussed above, one issue with current absorbent articles is that they are not configured for the specific needs of premature or NAS babies, in some instances, forcing nurses to handle these babies more than the nurses' desire. The configurable absorbent articles having removable fastening members of the present disclosure overcome the disadvantages of current premature and/or NAS baby absorbent articles by providing very narrow crotch regions, narrow chassis regions, small overall dimensions, soft skin-contacting surfaces, front and back umbilical cord notches (in some forms to create a reversible absorbent article), front and back reverse umbilical cord projections (in some forms to create a reversible absorbent article), discrete and removable fastening members (to allow nurses to configure the absorbent articles as needed and have fastening flexibility), one or more wetness guards, and/or low opacity outer cover nonwovens and/or backsheets, for example. The discrete and removable fastening members may have slots or apertures formed therein, so that tubes or hoses used to aid or monitor the health of the premature or NAS babies may be inserted therethrough without disturbing the baby or without the need for moving the baby. These slots or apertures may also help hold the tubes or hoses in place. Low opacity backsheets and/or outer cover nonwoven materials may be helpful in identifying when the absorbent article needs changed without the need for moving the babies. In some forms, the configurable absorbent articles of the present disclosure may allow for use without any fastening members, owing to the discrete and removable fastening members. This may be desired by nurses in some instances and may reduce the need to touch or move the baby. Furthermore, the absorbent articles of the present disclosure may also be reversible to allow the nurse to apply the absorbent article as he/she desires or as is needed. Absorbent materials in absorbent cores of the absorbent articles may be homogeneous to allow for reversible use. Further, the absorbent cores may have an extended hourglass shape to help narrow the crotch region and provide for more fit options and leg placements.
The absorbent articles of the present disclosure may comprise one or more wetness guards. The wetness guards may comprise one or more liquid impermeable materials, such as films or nonwoven materials, and one or more non-film materials, such as one or more nonwoven materials. The wetness guards may be positioned in areas of the absorbent articles that come into contact with a baby's lower back, waist, and/or legs, but not be positioned where a crotch area of the baby contacts the absorbent article. The non-film material may face toward the baby to provide comfort, while the liquid impermeable material may face away from the baby. The wetness guards may accomplish at least two functions. First, when a baby urinates, the urine is typically wicked away from the point of entry into the absorbent core throughout the absorbent core (both laterally and longitudinally). This may cause areas of the absorbent pad where the baby's lower back, waist, and/or legs are to be wet. The wetness guards provide a barrier between the wet areas and the baby's lower back, waist, and/or legs thereby leading to improved skin health for the baby. Second, the wetness guards may comprise soft non-film materials facing the baby's skin. As such, the baby's lower back, waist, and/or legs may rest on a soft, comfortable material again leading to improved skin health.
The fully removable fastening members may allow caregivers to attach and remove the fasteners as desired at any orientation and/or at any angle. For example, the fully removable fastening members may attach to themselves (or to each other—overlapping fasteners) or may be attached to any portion of a garment-facing surface of the configurable absorbent articles and to any other portion of the garment-facing surface of the configurable absorbent articles. This provides caregivers with great flexibility for various scenarios of how an absorbent article would be fastened on a premature or NAS infant, which may be quite different than conventional taped diapers. The fully removable fastening members may have certain stretch characteristics to allow for attachment without moving the infant. For example, if the fully removable fastening member is provided already having a first fastener removably attached to the back waist region of the absorbent article, a caregiver may need to stretch the removable fastening member so that the second fastener may be fastened. The removable fastener member should be stretchable enough so that upon application of a pulling force to the fastener, the infant does not move or slide. Stated another way, the removable fastening members should allow for a great deal of stretch at a low force so that the caregiver can easily pull on the removable fastening member and fasten the second fastener without disturbing or sliding the infant. In addition to stretch, the removable fastening members, in certain configurations, may have a length that prevents, or at least inhibits, fastener to skin engagement to protect the skin of the infant wearer.
Additionally, owing to the fact that the fastening members are removable and attachable as desired, a waist or hip circumference of variously sized infants may easily be fit properly with the same absorbent article. Stated another way, the absorbent articles of the present disclosure comprising one or two fully removable fastening members allow a waist opening of the absorbent articles to be significantly adjustable from a very small size to a larger size. This is important in the premature and NAS baby context in that these babies are in a variety of sizes of development and have various waist opening requirements for various conditions.
Absorbent articles for premature and NAS babies have certain requirements to provide adequate fit and comfort to the babies. There is more to making absorbent articles for premature and NAS babies than simply making conventional diapers smaller. In fact, the inventors have found that certain ratios of various product features, in combination with the removable fastening members of the present disclosure, provide a better fit, while still providing comfort to the babies.
These and other advantages of the configurable absorbent articles having removable fastening members of the present disclosure are set forth herein in greater detail.
The various absorbent articles may be placed in packages. The packages may be sold in arrays or on-line arrays.
While the specification concludes with claims particularly pointing out and distinctly claiming the subject matter which is regarded as forming the present invention, it is believed that the invention will be better understood from the following description which is taken in conjunction with the accompanying drawings in which the designations are used to designate substantially identical elements and in which:
Various non-limiting forms of the present disclosure will now be described to provide an overall understanding of the principles of the structure, function, manufacture, and use of the configurable absorbent articles having removable fastening members disclosed herein. One or more examples of these non-limiting forms are illustrated in the accompanying drawings. Those of ordinary skill in the art will understand that the configurable absorbent articles having removable fastening members specifically described herein and illustrated in the accompanying drawings are non-limiting example forms and that the scope of the various non-limiting forms of the present disclosure are defined solely by the claims. The features illustrated or described in connection with one non-limiting form may be combined with the features of other non-limiting forms. Such modifications and variations are intended to be included within the scope of the present disclosure.
As used herein, the terms “join” and “joined” encompass configurations whereby an element is directly secured to another element by affixing the element directly to the other element, and configurations whereby an element is indirectly secured to another element by affixing the element to intermediate member(s) which in turn are affixed to the other element.
As used herein, the term “array” means a display of packages comprising disposable absorbent articles of different sizes having like article constructions. Packages for the absorbent articles have the same brand and/or sub-brand, and the packages are oriented in proximity to each other in a given area of a retail store. An array is marketed as a line-up of products normally having like packaging elements (e.g., packaging material type, film, paper, dominant color, design theme, etc.) that conveys to consumers that the different individual packages are part of a larger line-up. Arrays often have the same brand, for example, “Pampers®.” In other instances, the arrays may have brands from the same manufacturer, such as “Pampers®” and “Luvs®”, for example.
Arrays also often have the same trademarks, including trademarks of the brand, sub-brand, and/or features and/or benefits across a line-up.
As used herein, the term “on-line array” means an “array” distributed by a common on-line source.
Configurable absorbent articles that provide improved fit, more flexible application options, narrow crotch regions, bodily exudate containment and improved skin health for premature, NAS, and other babies (or other wearers) are provided herein.
The absorbent articles 10 may comprise a first end edge 28 on a first side of the lateral axis 12 and a second end edge 30 on a second side of the lateral axis 12. The absorbent articles 10 may comprise a first side edge 32 on 7a first side of the central longitudinal axis 14 and a second side edge 34 on a second side of the central longitudinal axis 14. The absorbent articles 10 may comprise a liquid permeable material or liquid permeable topsheet 36, a liquid impermeable material or liquid impermeable backsheet 38, and an absorbent core 40 positioned at least partially intermediate the topsheet 36 and the backsheet 38.
The topsheet 36, the backsheet 38, and the absorbent core 40 may be manufactured of any suitable materials. Suitable topsheet materials may comprise porous foams, reticulated foams, apertured plastic films, or woven or nonwoven webs of natural fibers (e.g., wood or cotton fibers), synthetic fibers (e.g., polyester or polypropylene fibers), non-apertured material, apertured materials, apertured nonwoven materials, apertured nonwoven materials that are produced using an overbonding and ring rolling process, or a material having a combination of natural and synthetic fibers. Spunbond high loft materials may also be used, whether apertured or non-apertured. The topsheet 36 may have an embossed pattern, graphics, patterned, indicia, and/or three-dimensional features, either along with or instead of apertures. In some instances, the topsheet 36 may be a planar topsheet. In other instances, the topsheet may be a topsheet like that disclosed in U.S. Patent Application Publication No. 2015/0250662, to Isele et al., filed on Mar. 2, 2015 or in U.S. Patent Application Publication No. 2016/0136014, to Arora et al., filed on Nov. 5, 2015. The topsheet may be hydrophobic or hydrophilic. If the topsheet is apertured, it may be desirably to have the topsheet by hydrophobic.
Suitable backsheet materials may comprise breathable materials or highly breathable materials that permit vapors to escape from the absorbent article 10 while still preventing, or at least inhibiting, bodily exudates from passing through the backsheet 34 (i.e., liquid impermeable materials). Such materials may comprise nonwoven materials, woven materials, films, and/or laminates comprising a combination of one or more of these materials. Other backsheet materials may be non-breathable materials, such as films, for example.
One measure of the breathability of a backsheet or backsheet/outer cover nonwoven material laminate is the perviousness of the backsheet or the laminate to the passage of water vapor, reflected by the moisture vapor transmission rate (MVTR) of the backsheet or laminate. The MVTR of the laminate or backsheet may be in the range of about 500 g/m2/24 hr to about 5000 g/m2/24 hr, about 1000 g/m2/24 hr to about 4000 g/m2/24 hr, or about 2000 g/m2/24 hr to about 3000 g/m2/24 hr, specifically reciting all 0.1 g/m2/24 hr increments within the above-referenced ranges and all ranges formed therein or thereby.
The MVTR can be determined by placing a quantity of a hydrophilic material, such as calcium chloride, into a non-porous, open-top vessel (not shown) having an outwardly-extending flange around the vessel opening. A portion of the material for which the MVTR is to be determined is placed in overlying relationship relative to the vessel opening and is in contact with the flange of the vessel to completely cover the open end of the vessel. An annular gasket and an annular retaining ring are then placed over the material to be tested and are securely clamped to the vessel flange by any convenient clamping arrangement, to tightly and completely seal the periphery of the vessel opening in order that transmission of air or moisture vapor can only occur through the material being tested. The resulting assembly is then weighed to determine the initial weight of the vessel and its contents.
After the initial weight has been determined, the assembly is placed in a chamber having a constant temperature (40° C.) and a constant humidity (75% relative humidity). The vessel is maintained under those atmospheric conditions for a period of five (5) hours, after which it is removed from the chamber, wrapped tightly with an impervious film to prevent transfer of moisture into and out of the vessel, and is allowed to reach thermal equilibrium with the ambient atmosphere in which the weigh balance is located. Thermal equilibrium is achieved in about 30 minutes, after which the film overwrap is removed from the vessel, which is again weighed to determine the final weight of the vessel and its contents.
The MVTR is calculated by the following formula, which provides the MVTR in g/m2/24 hr:
A suitable absorbent core 40 for use in the absorbent articles 10 of the present disclosure may comprise any absorbent material 42 which is generally compressible, conformable, non-irritating to the wearer's skin, and capable of absorbing and retaining bodily exudates. In addition, the configuration and construction of the absorbent core 40 may also be varied (e.g., the absorbent core(s) or other absorbent structure(s) may have varying caliper zones, hydrophilic gradient(s), a superabsorbent gradient(s), or lower average density and lower average basis weight acquisition zones; or may comprise one or more layers or structures). In other instances, the configuration and construction of the absorbent core 40 may be uniform and homogeneous, such that the absorbent article 10 can be reversible. In such an instance, the absorbent material 42 may be uniform and homogeneous (i.e., not profiled). In some forms, the absorbent core 40 may have an hourglass shape, an extended hourglass shape, or rectangular shape, for example.
The absorbent material 42 may comprise superabsorbent polymers, co-form, foams (including but not limited to High Internal Phase Emulsion foams), air-felt (cellulosic material), or mixtures thereof. In some forms the absorbent material 42 may comprise less than 30%, less than 35%, less than 40%, at least 40%, at least 50%, at least 75%, at least 80%, at least 85%, at least 90%, at least 95%, at least 97%, at least 98%, at least 99%, or 100% superabsorbent polymers, by weight of the absorbent material. In other forms, the absorbent material 42 may only comprise air-felt and may be free of, or substantially free of (e.g., less than 5% by weight of the absorbent material) any superabsorbent polymers. The absorbent material 42 may have air-felt and less than 15% of superabsorbent polymers, less than 10% of superabsorbent polymers, less than 5% of superabsorbent polymers, less than 3% of superabsorbent polymers, or less than 1% of superabsorbent polymers. In other forms, the absorbent material 42 may comprise a mixture of air-felt and superabsorbent polymers (e.g., 30% to 70% air-felt and 30% to 70% superabsorbent polymers).

In other instances, the absorbent articles 10 may not comprise any cuffs, but some form of raised barriers may be used in their place. A pair of raised barriers may be attached to the topsheet 36, positioned under the topsheet 36, or formed from a portion of the topsheet 36 and/or acquisition or distribution materials. The raised barriers may comprise flexible foams, liquid impermeable materials, nonwoven materials, films, and/or other suitable materials. The raised barriers may be “raised” relative to the topsheet 36 and may act in a similar fashion as the cuffs 26 and 27, thereby causing bodily exudates to remain over the absorbent core 40 such that they can be absorbed by the absorbent core 40. The raised barriers may have any suitable thickness measured in a direction parallel to the lateral axis 12, such as 2 mm to 10 mm, for example. In some instances, one raised barrier may be provided and this single raised barrier may fully surround, or partially surround, the absorbent core 40 or portions thereof. The raised barriers may be raised a suitable amount from the topsheet 36 to contain the bodily exudates within the absorbent articles 10, such as in the range of 1 mm to 30 mm, or 2 mm to 20 mm, for example. Further details regarding raised barriers, including example structures and shape can be found in U.S. Patent Application. Publ. No. 2014/0171898 to Greening II, et al. The raised barriers may be used with at least one pair of cuffs as well for better containment. The cuffs may be positioned laterally inboard or laterally outboard of the raised barriers. The raised barriers or the cuffs 26, 27 may be referred to as “bodily exudate containment means”.

A first portion 80 of the second wetness guard 24 may be joined to the cuffs 26, 27, the raised barriers 56, the topsheet 36, and/or the backsheet 38 proximate to the second end edge 30 of the absorbent article 10. A second portion 82 of the second wetness guard 24 may be joined to the cuffs 26, 27, the raised barriers, the topsheet 36, and/or the backsheet 38 proximate to the first side edge 32 of the absorbent article 10. A third portion 84 of the second wetness guard 22 may be joined to the cuffs 26, 27, the raised barriers, the topsheet 36, and/or the backsheet 38 proximate to the second side edge 34 of the absorbent article 10. The joining may comprise using mechanical joining or adhesive joining, for example. The joining may be intermittent or continuous.

In other instances, the first and/or the second wetness guards 22 and 24 may be joined to the topsheet 36, the cuffs 26, 27, the raised barriers, and/or the backsheet 38 at any suitable locations on a wearer-facing surface of the absorbent article 10. In an instance, all, or some of the perimeters of the wetness guards 22 and 24 may be joined to the wearer-facing surface. In other instances, all or some of non-perimeter areas may be joined to the wearer-facing surface. The two wetness guards 22 and 24, if both are provided, may be joined to a portion of the wearer-facing surface in the same fashion or in different fashions. In an instance, one or both of the wetness guards 22 and 24 may be discrete components that are not joined to the absorbent article 10 in a package, but instead are provided as a discrete component. Nurses or caregivers may then position the wetness guard or guards on portions of the wearer-facing surface of the absorbent articles 10 as appropriate. The wetness guards 22 and 24 may have a space between themselves and the first and second end edges 28 and 30. Stated another way, the most longitudinally outward portions of each wetness guard does not have to be positioned on the first end edges 28 or the second end edge 30, but instead a gap may exist, such as a 0.5 inch gap, for example.
The wetness guards 22 and 24 may have the same construction or a different construction. Referring to
The first and second wetness guards 22 and 24 may form a crotch receiving area 92 in the absorbent article 10. The crotch receiving area 92 is the area between the two wetness guards 22 and 24 where a baby's crotch area is positioned when the absorbent article 10 is positioned on the baby. The crotch receiving area 92 between the first and second wetness guards 22 and 24 may be any suitable size (length or width) for a particular size baby. A ratio of the surface area of the crotch receiving area 92 to the wetness guards 22 and 24 (together or separate if only one is provided) may be about 7:1, about 6:1, about 5:1, about 4:1, about 3:1, about 2:1, about 1:1, or about 0.5:1, or may be in the range of about 10:1 to about 1:1, specifically reciting all 0.1 increments of the ratios specified above and all ratios formed within the specified range. The crotch receiving area 92 may have an area in the range of about 25 cm2 to about 750 cm2, about 40 cm2 to about 500 cm2, about 50 cm2 to about 400 cm2, about 50 cm2 to about 250 cm2, about 50 cm2 to about 200 cm2, about 50 cm2 to about 150 cm2, about 50 cm2 to about 100 cm2, or about 60 cm2 to about 80 cm2, for example, specifically reciting all 0.1 cm2 increments within the specified ranges and all ranges formed therein or thereby.
The absorbent article, when laid flat, elastic contraction pulled out, may have a length, in a direction parallel to a central longitudinal axis 14, of less than 500 mm, less than 400 mm, less than 300 mm, less than 275 mm, but at least 100 mm. The absorbent article, when laid flat, elastic contraction pulled out, may have a width, in a direction parallel to a central lateral axis 12 of less than 200 mm, less than 150 mm, less than 130 mm, less than 100 mm, but at least 50 mm.
To create the first and/or second wetness guards 22 and 24, the backsheet 38 and the outer cover nonwoven material 58 may extend beyond the first and second end edges 28 and 30 and be folded over the wearer-facing side of the absorbent article 10. The folded over portions of the backsheet 38 and the outer cover nonwoven 58 may be joined to the topsheet 36, portions of the cuffs 26, 27, the raised barriers, and/or the backsheet 38. As such, the folded over portion of the backsheet 38 may form the first liquid impermeable material 86 and the outer cover nonwoven material 58 may form the second liquid permeable material 88 of the wetness guards 22 and 24. In other instances, the backsheet 38 and the outer cover nonwoven material 58 may not be joined to a portion of the wearer-facing surface, but instead may merely be folded over the wearer-facing surface.
In another instance, the first and/or second wetness guards 22 and 24 may be formed from discrete laminates each comprising the first liquid impermeable material 86 and the second liquid impermeable material 88. These discrete laminates may be joined to the topsheet 36, portions of the cuffs 26, 27, portions of the raised barriers, and/or to the backsheet 38.
The absorbent article 10 may have a wearer-facing surface area (the entire wearer-facing surface including areas of the wetness guards) in the range of about 150 cm2 to about 1,500 cm2, about 175 cm2 to about 1,000 cm2, about 200 cm2 to about 800 cm2, about 200 cm2 to about 500 cm2, about 200 cm2 to about 400 cm2, about 200 cm2 to about 300 cm2, about 200 cm2 to about 250 cm2, about 210 cm2 to about 240 cm2, or about 225 cm2, for example, specifically reciting all 0.1 cm2 increments within the specified ranges and all ranges formed therein or thereby.
The wetness guards 22 or 24 may have an area in the range of about 10 cm2 to about 800 cm2, about 15 cm2 to about 600 cm2, about 15 cm2 to about 400 cm2, about 20 cm2 to about 300 cm2, about 20 cm2 to about 200 cm2, about 20 cm2 to about 100 cm2, about 20 cm2 to about 75 cm2, or about 25 cm2 to about 70 cm2, for example, specifically reciting all 0.1 cm2 increments within the specified ranges and all ranges formed therein or thereby. As mentioned above, the wetness guard 22 may have an area that is the same or different than the wetness guard 24, if both are provided in an absorbent article.

Since the fastening members 100 are removable from the absorbent article 10, they can be fastened as desired or as needed by a nurse or caregiver. In some instances, the nurse or caregiver may remove the fastening members 100 from the absorbent article 10 and not use them if the baby is in a certain position, for example. In other instances, the nurse or caregiver may only use one of the fastening members 100 if the baby is in another certain position, for example.

The umbilical cord projections may have one or more slots 130 or apertures defined therein. The slots 130 or apertures may have any suitable size and/or shape. In certain instances, premature, NAS babies, and other babies may be on feeding tubes, corded monitoring device (e.g., heart rate monitor), or the like. These tubes and cords may be positioned through the slots 130 or apertures to help hold the tubes and cords in place.
In some instances, no umbilical cord notches or umbilical cord projections may be provided on an absorbent article (see e.g.,
As mentioned above, it may be desirable to reduce contact with premature and NAS babies as much as feasible because of their delicate body and skin. On the other hand, it is also desirable to have the absorbent article on the baby to be as free of bodily exudates as possible to protect the baby's skin. In instances where the babies are positioned in incubators, conventional wetness indicators may not function adequately owing to the high humidity environment of the incubators. The present disclosure provides a way to solve these issues by providing the outer cover nonwoven material 58 and/or the backsheet 38 with a low opacity. By providing the outer cover nonwoven material 58 and/or the backsheet 38 with a low opacity, nurses are able to visually determine, without touching the baby, whether the absorbent articles need to be changed, thus not disturbing the baby if the absorbent article is not soiled or sufficiently soiled.
Either in addition to or in lieu of the low opacity outer cover nonwoven material 58 and/or the backsheet 38, the absorbent article 10 may comprise a wetness indicator 132, which may be positioned on a wearer-facing side of the backsheet 38 or in other suitable locations. The wetness indicator may be visible from a wearer-facing surface or a garment-facing surface of the absorbent article 10. Thus, as bodily exudates come into contact with the wetness indicator, the wetness indicator may change colors or appear or disappear to indicate to nurses or caregivers that the absorbent article is soiled and needs changed. In other instances, the wetness indicator may change colors, appear, or disappear based on temperature changes (caused by bodily exudates entering the absorbent article) within the absorbent article 10. In other instances, the absorbent article 10 may be free of a wetness indicator.
The absorbent articles 10 may comprise lotions, ointments, skin protecting ointments, vitamins, anti-bacterial treatments, anti-microbial treatments, anti-fungal treatments, on the topsheet 36, leg cuffs 26 and/or 27, and/or other components to promote skin health for the baby.
By having graphics 134 and 136 that are mirror images of each other, relative to the central lateral axis 12, the absorbent article 10 may be reversible. Stated another way, a baby's (or wearer's) back waist region may be positioned adjacent to graphics 134 or 136 depending on how the absorbent article 10 is donned on the baby. If the absorbent article 10 is meant to be reversible, the absorbent material 42 within the absorbent core 40, in some instances, may be uniform and homogeneous. The absorbent core 40 may also be longitudinally centered in the absorbent article to aid in reversibility of the absorbent article. By providing graphics that mirror each other on opposite sides of the central lateral axis 12, a caregiver will quickly recognize that the absorbent article is reversible. Further, the graphics may indicate where fasteners (e.g., 110, 112) may be attached (e.g., landing zone) on the garment-facing surface to provide a caregiver with a guide as to proper application of the fasteners and, thereby, a proper application of the absorbent article 10.

As mentioned above, it may be desirable to provide an absorbent article with one or two removable fastening members (e.g., 100 herein), each having a first fastener (e.g., 110 herein) and a second fastener (e.g., 112 herein). The first and second fasteners may comprise hooks, loops, adhesives, cohesives, and/or other materials described herein. The first fastener of each of the removable fastening members may be attached in a second or back waist region of the absorbent article. The second fastener of each of the removable fastening members may be attached to themselves (for ease in processing) and may be free of attachment to a first or front waist region of the absorbent article. The second fastener may also be attached to another portion of the absorbent article. The first fasteners may be attached by a machine to the back waist region and the second fasteners may be attached by a caregiver to the front waist region during application. To attach the first fasteners to the front waist region it may be desirable to provide the fastening members with a high stretch at a low pulling force. First, this helps in not disturbing the attachment of the second fasteners to the back waist region (i.e., helps reduce “pop-off”). Second, this helps in not moving or sliding the infant through the pulling force.
The absorbent articles of the present disclosure may have a significantly adjustable waist circumference owing to the provision of/use of at least one fully removable fastening member or two fully removable fastening members. Since the fasteners of the fully removable fastening members may be attached at any location, or at any location proximate to the waist circumference, such as around the hip circumference of a wearer, the waist circumference or the hip circumference may be significantly adjustable to fit a wide range of wearers having different waist or hip circumferences. To provide a small waist or hip opening circumference in the absorbent article, only one removable fastening member may be used. In other instances, two removable fastening members may be used and may or may not be partially overlapped with each other. Stated another way, if the fastening members form a ring proximate to a waist opening of the absorbent article, there may be areas of the ring where a first removable fastening member is overlapped with a second removable fastening member. In such an instance, fasteners of a first removable fastening member may be attached to garment-facing surfaces of the absorbent article and one fastener of a second fastening member may be attached to a garment-facing surface of the first fastening member with the other fastener attached to the garment-facing surface of the absorbent article. To provide a larger waist opening circumference in the absorbent articles, the removable fastening members would generally not overlap each other. In such an instance, the removable fastening members would attach in such a fashion as to make the waist opening circumference as large as possible and would themselves form part of the waist opening circumference.
Referring to
The adjustable waist or hip circumference may be configured to fit a range of, or may be adjustable to, about 70 mm to about 275 mm, about 100 mm to about 250 mm, about 100 mm to about 200 mm, in an unstretched state, for example, depending on whether one or two removable fastening members are used.
The adjustable waist or hip circumference may be configured to fit a range of, or may be adjustable to, about 80 mm to about 300 mm, about 100 mm to about 250 mm, about 120 mm to about 230 mm, in a stretched state, for example, depending on whether one or two removable fastening members are used.
The adjustable waist or hip circumference may be configured to fit a range of, or may be adjustable to, about 80 mm to about 160 mm, about 90 mm to about 150 mm, about 100 mm to about 150 mm, in a stretched state, for example, if a single removable fastening member is used.
Specifically reciting all 0.1 mm increments within the ranges specified in the above-three paragraph and all ranges formed therein or thereby.
The fasteners of the removable fastening members may, in some instances, be attached to one or more discrete landing zones on a garment-facing surface, or other surface, of the absorbent articles of the present disclosure. The one or more discrete landing zones may be positioned in the front or first waist region, the back or second waist region, or the crotch region of an absorbent article of the present disclosure. Any suitable number of discrete landing zones may be provided, such as one, two, three, four, five, six etc., for purposes of adjustability of fastening. A single discrete landing zone may be provided proximate to or overlapping a central longitudinal axis of the absorbent article, for example. Multiple discrete landing zones may be provided at various location such that the waist opening circumference or hip circumference may be adjusted. The multiple discrete landing zone may have different sizes and/or shapes and/or the same size and/or shapes.

Ratios of Absorbent Article Features
Owing to the fact that the absorbent articles of the present disclosure are designed for premature and/or NAS babies, these absorbent articles have special requirements for various features to accommodate such small users and their specific needs. These special requirements are more than just making a smaller diaper to fit these wearers. Certain sizes, areas, and ratios of various product features and components, especially the removable fastening members, aid in proper fit, superior performance, and most importantly comfort for the small wearers.
In the below, “length” means a distance measured in a direction that is parallel to a longitudinal axis of an absorbent article of the present disclosure. “Width” means a distance that is measured in a direction that is perpendicular to a lateral axis of an absorbent article of the present disclosure. “Area” means normal calculations of area, such as length×width for a rectangle, for example.
Fastener Area (e.g., 1 Area of Hooks)
The fasteners (e.g., 110, 112) (e.g., 1 area of hooks) may have an area in the range of about 0.0001 m2 to about 0.0009 m2, of about 0.0001 m2 to about 0.0006 m2, or of about 0.0001 m2 to about 0.0005 m2, specifically reciting all 0.0001 m2 increments within the specified ranges and all ranges formed therein or thereby.
Ratio of Single Removable Fastening Member Length to Total Absorbent Article Length
The ratio of a single removable fastening member length to a total absorbent article length may be in the range of about 0.075 to about 0.2, or of about 0.10 to about 0.19, specifically reciting all 0.001 increments within the specified ranges and all ranges formed therein or thereby.
Ratio of Single Removable Fastening Member Width to Total Absorbent Article Length
The ratio of a single removable fastening member width to a total absorbent article length may be in the range of about 0.25 to about 0.50, or about 0.25 to about 0.75, specifically reciting all 0.01 increments within the specified ranges and all ranges formed therein or thereby. This ratio enables maximum waist or hip opening circumference with the least amount of force applied to the wearer (e.g., no or limited stretch in the removable fastening members).
Ratio of Single Removable Fastening Member Width to Total Absorbent Article Width
The ratio of a single removable fastening member width to a total absorbent article width may be in the range of about 0.60 to about 1.0, about 0.6 to about 0.99, about 0.6 to about 0.95, about 0.6 to about 0.90, specifically reciting all 0.01 increments within the specified ranges and all ranges formed therein or thereby. This ratio delivers the maximum waist or hip opening circumference adjustability for variously sized wearers.
Ratio of Fastener (e.g., 1 Area of Hooks) Length to Total Absorbent Article Length
The ratio of a fastener (e.g., 1 area of hooks) length to a total absorbent article length may be in the range of about 0.05 to about 0.18, about 0.05 to about 0.15, or about 0.05 to about 010, specifically reciting all 0.01 increments within the specified ranges and all ranges formed therein or thereby. This ratio helps with maximum customization of fit around the legs and waist opening to accommodate special care needs and safely fasten the fastener to the garment-facing surface of the absorbent article, or to a garment-facing surface of a removable fastening member, without undue concern that the fastener will contact the skin of the wearer.
Ratio of Fastener (e.g., 1 Area of Hooks) Width to Total Absorbent Article Width
The ratio of a fastener (e.g., 1 area of hooks) width to a total absorbent article width may be in the range of about 0.10 to about 0.25, or about 0.10 to about 0.25 specifically reciting all 0.01 increments within the specified ranges and all ranges formed therein or thereby. This ratio aids in the ease of fastener engagement for a caregiver.
Ratio of Fastener (e.g., 1 Area of Hooks) Area to Total Absorbent Article Area
The ratio of a fastener (e.g., 1 area of hooks) area to an absorbent article area may be in the range of about 0.015 to about 0.04, specifically reciting all 0.001 increments within the specified range and all ranges formed therein. This ratio provide for gentle fastening while still ensuring adequate fastener performance.
Ratio of Total Fastener (e.g., 4 Hooks) Area to Total Absorbent Article Area
The ratio of a total fastener (e.g., 4 hooks) area to a total absorbent article area may be about 0.07 to about 0.15, specifically reciting all 0.01 increments within the specified range and all ranges formed therein. The total fastener area is the sum of all of the fasteners areas on both of the removable fastening members, so four fasteners total.
Ratio of Single Removable Fastening Member Area to Total Absorbent Article Area
The ratio of a single removable fastening member area to a total absorbent article area may be in the range of about 0.11 to about 0.15, specifically reciting all 0.01 increments within the specified ranges and all ranges formed therein or thereby. This ratio provides maximum adjustability at the waist opening circumference.
