The field of this invention relates generally to disposable absorbent fiber articles for absorbing fluids resulting from urinary incontinence and more particularly to disposable absorbent shields, barriers, liners, sheaths, layers, or napkins having an adjustable, conforming, adhering, fastening, and/or engaging placement and method.
Urinary incontinence, especially in some adult men, can be embarrassing and problematic. This problem is particularly acute for male adults who experience urinary flow irregularities, such as slow and intermittent urine dribbling and unpredictable dribbling. Often, the residual urine can flow unchecked which can soil, splotch, or stain the underclothing or trousers and cause embarrassment and discomfort. This condition can cause the affected individual emotional distress and adversely impact his personal esteem, mobility, and quality of life. Further, this residual moisture may irritate the skin of the scrotum and perineum. Conventional methods for addressing this problem include pads or diapers that often are uncomfortable or don't appeal to men. For example, men may feel embarrassed or are emotionally distressed by wearing a product that is similar to a diaper or a female menstrual cycle pad.
Moreover, conventional products are complex and may not adequately fit some of the men or include sufficient instructions for proper placement. Further, the necessity of making a variety of sizes available cause's consumers of conventional products to guess at what size is suitable for their particular body build and size. And, businesses must carry inventory of multiple product sizes, which often increases business costs. Although various devices and absorbent products have been proposed in the past to cope with these problems, these products have been too expensive, complex, or impractical in terms of male appeal, comfort, and ease of use. Accordingly, there is a need to provide a urinary incontinence article and method that overcomes these and other difficulties.
This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to be used to limit the claimed subject matter's scope.
As will be described in greater detail below, the various embodiments of the present disclosure provide for improved adjustability, conforming fit, and engaging, adhering, and/or fastening placement of disposable absorbent urinary incontinence articles. In particular, embodiments of the present disclosure allow the wearers of the absorbent article to more readily go about their daily tasks without the nuisance of an uncomfortable or embarrassing experience with conventional incontinence products. At least one object of embodiments of the present disclosure is to provide men who experience light, moderate, or non-extreme urinary incontinence, a disposable absorbent article that is designed to fit various body contours and sizes and facilitate various placements of the scrotum or genitals for comfort. In one aspect, a disposable absorbent article may include an absorbent structure that absorbs fluid, for instance a paper or napkin-like article made using virgin fiber or recycled fibers in order to achieve certain softness and strength attributes. The disposable absorbent article, for instance a sheath, liner, shield, layer, or barrier, is adapted to optionally provide either no, or at least one split, slit, or cleft, and thus at least one or two absorbent flaps, at the bottom of the sheath, barrier, or liner to facilitate comfortable placement of the scrotum or genitals as preferred by the wearer or user of the absorbent article and to achieve a snug, engaged, anchored, or form-fitting geometry and optional placement of more absorbent material where needed in the crotch region. The absorbent article is anchored, adhered, fastened, or engaged as an upper section of the article adheres or fastens to an under garment, at least a single flap of the article is placed atop the crotch region or crotch of underwear, (including briefs), or, at least one split engages with a crotch (the part of a garment that passes between the legs) of the underwear, undergarment, or undershorts, in particular boxer shorts or boxer briefs to engage and minimize shifting or movement of the absorbent article with respect to the underwear. The one or more absorbent flaps may extend down over the underwear crotch region or crotch down toward and over the upper thighs of the user, under the thigh coverings of the underwear, or under the groin atop the crotch toward the rear of the underwear as a continuing sheath, liner, or barrier.
In another aspect, embodiments of the present disclosure may include placement or graduated indicia marked on the disposable absorbent article to indicate to a user proper placement of the article with respect to his underwear, torso length, and body size. The graduated indicia may be displayed as the article folds over a waistband of the supporting underwear or garment.
In another aspect, embodiments of the disclosure may include absorbent articles having adhering or fastening means, such as pressure sensitive adhesive, clipping, or connecting means, for attaching the article to a supporting garment. For instance, the adhesive may be applied to the bottom, garment-facing, surface of the article and include at least two parallel adhesive lines or strips covered by a protective release sheet. Alternatively, a fastening or clipping means, such as bent wire or plastic with shape retention, may be used to connect the absorbent article to the supporting underwear or garment. The adhering or fastening means may be applied to an outer surface of the garment once a portion of the article is folded over a waistband of the supporting garment and the protective sheet has been removed from the adhesive or the connecting means has been added. Alternatively, the adhering or fastening means may engage with the inner, body-facing surface of the undergarment prior to or without folding of the article over a waistband of the undergarment or underwear. The adhesive strips, fasteners, and/or article waistband fold-over are effective in preventing displacement of the article and in countering the shear forces exerted on the article, including forces from leg motion or body motion.
Still, in another aspect, a disposable absorbent article with an adjustable, body contour conforming fit and engaging placement may include an absorbent structure that is configured to sufficiently absorb fluid before the fluid reaches the users underclothing and outer clothing even, optionally, without inclusion of an impermeable layer in the absorbent structure. The disposable absorbent structure may include at least a one or two-ply (top sheet and back sheet) fiber based barrier, sheath, layer, or liner with a bottom or lower portion of the structure including at least a two or three-ply or more (top, middle, and bottom) fiber (or other absorbent material) based sheets. The third-ply or third layer may increase absorbency of the article as much as 50 percent compared to including a two-ply lower portion.
Both the foregoing general description and the following detailed description provide examples and are explanatory only. Accordingly, the foregoing general description and the following detailed description should not be considered to be restrictive. Further, features or variations may be provided in addition to those set forth herein. For example, embodiments may be directed to various feature combinations and sub-combinations described in the detailed description.
The accompanying drawings, which are incorporated in and constitute a part of this disclosure, illustrate various embodiments of the present invention disclosure. In the drawings:
Corresponding reference characters indicate corresponding parts, components, or elements throughout the drawings.
It is to be understood by one of ordinary skill in the art that the present disclosure is a description of exemplary embodiments, and is not intended as limiting the broader aspects of the present invention. In general, embodiments of present invention are directed to unobtrusive, convenient, and male-appealing absorbent articles incorporating at least one or two engaging conforming placement portions or absorbent flaps that may be placed in the frontal urinary area of a user and secured between the crotch area and the top of underwear briefs or boxer briefs or may anchor or engage the crotch of an undergarment and extend down toward and over the thighs of the user or thigh coverings of the undergarment, such as boxer shorts or boxer briefs, as a continuing sheath, liner, or barrier. Embodiments of the present invention also incorporate methods of manufacture, methods of use, and proper placement indicia visible to a user as the absorbent article is put in place and folded over a waistband of the user's underwear. Embodiments also include an adhering or fastening means operative to restrict movement of the article with respect to the undergarment and the user. For instance, adhesive temporarily covered by a protective sheet may be placed on a garment-facing side of the article to hold the article in place once it is folded over a waistband of the underwear or alternatively prior to or without folding the article over the waistband. In accordance with the present disclosure, the absorbent articles may include multiple paper layers made using virgin fiber or recycled fiber sheaths in order to achieve certain softness, absorbency, and strength attributes. In one embodiment, for instance, the multiple layers or sheets may be configured, attached, or connected together using thread, adhesive, or other adhering or connecting means. In this manner, the wearer experiences a comfortable and discrete fit even when the absorbent article has been insulted with a body fluid, such as urine.
The absorbent article 100 has a longitudinal direction 1 and a lateral direction 2. An embodiment of the illustrated absorbent article 100, for example, has a length L (i.e., the extent of the absorbent article in the longitudinal direction 1) of approximately 21.5 inches (54.6 cm) and a width W (i.e., the extent of the disposable absorbent article in the lateral direction 2) of approximately 7.5 inches (19 cm). Thus, the illustrated absorbent article 100 is generally rectangular. It is understood that the article 100 can have any suitable length and/or width. It is also understood that the absorbent article 100 can have any suitable shape (e.g., square, circular, elliptical).
As illustrated in
More specifically, the incontinence absorbent article 100 is structured for use with undershorts, underwear, or pants. The absorbent article 100 may include the upper portion 114 and the lower portion 117, where the lower portion 117 includes at least a portion of the absorbent body-side sheet 102 having a split 105 extending longitudinally from an edge of the lower portion 117 toward the upper portion 114 and forming at least two absorbent flaps 110 in the lower portion 117. The split 105 borders at least one side of the absorbent flaps 110. The absorbent flaps 110 are structured to engage with and extend downward beyond a crotch of the undershorts restrict lateral movement, and eventually downward movement, of the absorbent article 100 with respect to the undershorts or underwear. The split 105 may extend a distance greater than zero and less than about half of a length, L, of the absorbent article 100. Optionally, the split 105 may extend a distance greater than about half the length L, but less than L. For example, the split or slit 105 may extend a distance at, or greater than, about a sixteenth of the length L.
Alternatively, as described above, the absorbent article 100 may also include the back sheet 104 within at least the lower portion 117 where the body-side or top sheet 102 is above the back sheet 104. Still further, the article 100 may include the middle sheet 106 between the back sheet 104 and the top sheet 102, the middle sheet 106 being within at least the lower portion 117 of the article 100 where at least the middle sheet 106 and the top sheet 102 are each made from an absorbent material. Thus, the top sheet 102 can be liquid permeable and the back sheet may be liquid impermeable, the top sheet 102 being adjacent to the absorbent middle sheet 106 on a side opposite the back sheet 104. In an alternative embodiment, the back sheet 104 may also be liquid permeable. The back sheet 104 can also be made of an absorbent material and located within the upper portion 114 adjacent to the top sheet 102.
The absorbent article 100 can also include an absorbent wicking fold 130 disposed longitudinally on the top sheet 102 adding absorbent capabilities to the article 100 directing body fluid away from a user's skin. The absorbent article 100 also can include placement indicia 125 disposed on the upper portion 114 to allow a user to retain and adjust placement of the absorbent article 100. A segment of the upper portion 114 placed over a waistband of undershorts or underwear provides a reference point for placement of subsequent absorbent articles as well as restricts movement of the article (downward and upward) with respect to undergarments and garments.
As described in more detail below, the top sheet 102 may be made from a woven fabric, nonwoven fabric, liquid permeable film, or combinations thereof. The middle sheet 106, top sheet 102, and back sheet 104 can be made from cellulose, wood pulp, rayon, cotton, polymeric fibers, and combinations thereof.
With reference now to
It should be noted that the body-side top sheet 102 can also include or consist of a layer constructed of any operative material and may be a composite material. For example, the top sheet 102 may include a woven fabric, a nonwoven fabric, a polymer film, a film-nonwoven fabric laminate or the like, as well as combinations thereof. Examples of a nonwoven fabric useable in the top sheet 102 include, for example, an air-laid nonwoven web, a spunbond nonwoven web, a melt-blown nonwoven web, a bonded-carded web, a hydro-entangled nonwoven web, a spun-lace web or the like, as well as combinations thereof. Other examples of suitable materials for constructing the top sheet 102 can include rayon, bonded-carded webs of polyester, polypropylene, polyethylene, nylon, or other heat-bondable fibers, finely perforated film webs, net-like materials, and the like, as well as combinations thereof. These webs can be prepared from polymeric materials such as, for example, polyolefins, such as polypropylene and polyethylene and copolymers thereof, polyesters in general including aliphatic esters such as polylactic acid, nylon or any other heat-bondable materials. When the top sheet 102 is a film or a film laminate, the film should be sufficiently apertured or otherwise be made to allow fluids to flow through the top sheet 102 to the absorbent structure 104 or 106.
Other examples of suitable materials for the top sheet 102 are composite materials of a polymer and a nonwoven fabric material. The composite materials are typically in the form of integral sheets generally formed by the extrusion of a polymer to form a nonwoven web, such as a spun-bond material. In a particular arrangement, the top sheet 102 can be configured to be operatively liquid-permeable with regard to the liquids that the pad is intended to absorb or otherwise handle.
It is contemplated that the top sheet 102 can have the same extent as the middle sheet 106 and/or back sheet 104 or can have an extent less or greater than the middle sheet and/or back sheet. It is further contemplated that in some embodiments (not shown), the top sheet 102, middle 106, and/or the bottom sheet 104 can be omitted. Thus, in such embodiments, the disposable absorbent article 100 may comprise the middle sheet 106 and/or the back sheet 104. Other suitable materials which can be used to form the middle sheet 106, top sheet 102, or back sheet 104 include those materials used in absorbent pads, or in 1, 2, or 3-ply napkins or towels, as may be manufactured, for instance by Georgia Pacific Corporation or Kimberly Clark Corporation, and include materials, such as, for example, cellulose, wood pulp fluff, rayon, cotton, and melt-blown polymers such as polyester, polypropylene, various fibers, or coform nonwoven. Coform nonwoven is a melt-blown air-formed combination of melt-blown polymers, such as polypropylene, and absorbent staple fibers, such as cellulose.
The top sheet 102, back sheet 104, and/or the middle sheet 106 can also be formed from a composite comprised of a hydrophilic material which may be formed from various natural or synthetic fibers, wood pulp fibers, regenerated cellulose or cotton fibers, or a blend of pulp and other fibers. One particular example of a material which may be used as the absorbent structure is an air-laid material. The absorbent structure may also include a superabsorbent material to increase absorbency and minimize odor.
The absorbent article 100 can also include a split, slit, or cleft 105, at least two absorbent flaps 110, connecting means 120, for instance sewn stitching or adhesive connecting the multiple layers or napkins, graduated indicia 125 (optionally perforated), and wicking fold 130. The at least two flaps 110 in the lower portion 117 are configured to fit or engage over the crotch of the user's underwear whether the user comfortably “wears” or places his genitals or scrotum to his left, center, or right. The split 105 facilitates the anchoring or engagement of at least one flap 110 to a crotch of the user's underwear (e.g. boxer shorts or briefs) on the right or left side or center (fold over crotch engagement) for more absorbency and a customized comfort fit that minimizes movement of the absorbent article 100. The flaps 110 extend down toward and over the upper thighs of the user or under thigh coverings of the underwear as a continuing absorbent sheath, liner, or barrier.
Similarly, the absorbent article 200 can include the upper portion 214, the lower portion 217, optionally with respect to
The at least two flaps 310 and the at least one adjunct flap 315 in the lower portion 317 are configured or structured to engage over and with the undergarment crotch whether the user comfortably “wears” or places his genitals or scrotum to his left, center, or right. The split 305 facilitates the anchoring of at least one flap 310 or 315 on the right or left side or center for more absorbency and a customized comfort placement that minimizes movement of the absorbent article 300 once its inserted or installed. The adjunct flap 315 allows for even more flexible placement of more absorbency within the crotch region as desired by the user. The graduated placement indicia 325 allow the user to find and remember the most appropriate placement of the absorbent article 300 for his torso size and body build. As described in more detail below with respect to
As described above, the method of placing the absorbent article 100 for male incontinence includes the step of folding an upper portion of the article having laterally disposed indicia 125 over a waistband 715 of underclothing 602. This placement restricts downward and upward movement of the article 100 with respect to the underclothing 602. The indicia 25 indicate a location best fitting a user. The method further includes straddling the crotch 607 of the underclothing 602 with the flaps 110 and split 105 thus, restricting a lateral and, eventually, downward movement of the absorbent article with respect to the underclothing. The split 105 may extend longitudinally toward an upper portion of the article 100 a distance between about a sixteenth of the full length of the article and about the full length of the article.
The absorbent article 100 flaps 110 are structured to: straddle the crotch 607 of the undergarment 602, restrict lateral movement of the absorbent article 100, and extend to a thigh region 710 of a user. The placement indicia 125 marked on and an upper portion of the article 100 body side sheet folds over the waistband 715 of the undergarment 602 at a placement setting desired by a user of the absorbent article, the placement setting chosen among the placement indicia 125.
As described above, the method of placing the absorbent article 1105 for incontinence includes the step of folding an upper portion of the article having laterally disposed indicia 1125 over the waistband 1012 of briefs 1010 and adhering the article 1105 to the briefs 1010 with and adhering or fastening means 1120 such as adhesive or a clip. This placement restricts downward and upward movement of the article 1105 with respect to the underclothing 1010. The indicia 1125 indicate a repeatable location best fitting a user.
