Body adhering absorbent articles adapted for use as feminine hygiene articles have been previously disclosed. These feminine hygiene articles generally include body adhesive applied to the body-side surface of the absorbent article and are adapted to attach directly to the wearer's skin. However, in some cases, the body adhesive can become contaminated during storage and/or application to the body.
To avoid contaminating the adhesive during storage and before application, the body adhesive is usually covered by one or more peel strips. These peel strips are removed prior to application. The peel strip removal usually involves grasping an edge of the peel strip or a finger tab between the thumb and forefinger and completely removing the peel strip from the absorbent article. Removal of the peel strip consequently exposes the attachment zone and the body attachment adhesive disposed thereon.
Typically, the user then grasps the attachment zone by placing their thumb on the body attachment adhesive and their forefinger on the adjacent shell surface. The product is then positioned and attached to the body. While this traditional product form and method for applying to the body provides suitable function, there are some aspects that can be improved.
For example, the above described donning process can lead to adhesive contamination. Specifically, when the user touches the body attachment adhesive, any oil, lotion, or other contaminates that are present on the skin of the hand of the wearer may be transferred to the body attachment adhesive, which in turn may reduce its effectiveness. Since the donning process frequently takes place immediately after removal of a previously used product and before the opportunity to wash hands, the skin of the hand may also include other contaminating body exudates.
Additionally, previously disclosed body-adhering articles and donning processes may increase the likelihood of errant attachment. Errant attachment is especially problematic because of the size and flexibility of the product and the region of the body where the product needs to be attached. For example, errant attachment may occur if the body adhesive contacts clothing during the donning process or the body adhesive is improperly positioned on the body. Errant attachment may also occur if exposed adhesive folds over onto itself. At best, this requires separation of the attached pieces with some loss of adhesion. At worse, the folded over section cannot be corrected and may result in a product being unfit for use.
In one aspect, the present invention provides an absorbent article having a shell and an absorbent component. The shell defines, in a longitudinal direction, an anterior attachment region, an anterior separation zone, an absorbent component region, a posterior separation zone, and a posterior attachment region. The anterior separation zone separates the anterior attachment region from the absorbent component region and the posterior separation zone separates the posterior attachment region from the absorbent component region. The anterior attachment region includes an anterior body adhesive and defines a protected condition where the anterior body adhesive is fully covered by one or more anterior peel strips. The anterior attachment region is adapted to transition from the protected condition to a fixed donning condition. In the fixed donning condition a portion of the anterior body adhesive is exposed and a portion of the anterior body adhesive is covered by the one or more anterior peel strips. The anterior attachment region is adapted to transition from the fixed donning condition to a fully exposed condition. In the fully exposed condition the anterior body adhesive is fully exposed.

Now with reference to
As used herein, “body-facing surface” means that surface of the absorbent article which is intended to be disposed toward or placed adjacent to the body of the wearer during ordinary use. The “garment-facing surface” is on the opposite side of the absorbent article from the body-facing surface. The garment-facing surface is an outward surface of the absorbent article and is intended to be disposed to face away from the wearer's body during ordinary use. The garment-facing surface is generally arranged to face toward or placed adjacent to the wearer's undergarments when the absorbent article is worn.
Body-adhering absorbent article 20 includes a shell 29 and an absorbent component 40. The shell 29 further includes any suitable body adhesive 34. The body adhesive 34 may be applied to shell 29 at any suitable location via any suitable means. In some embodiments, the body adhesive 34 may be incorporated as part of an adhesive transfer layer 32. The adhesive transfer layer 32 may include any suitable configuration. For example, the adhesive transfer layer 32 may consist of construction adhesive 33, body adhesive 34, nonwoven carrier 35, and one or more peel strips 36.
In addition to the shell 29 and the adhesive transfer layer 32, the body adhering absorbent article 20 also includes an absorbent component 40, which is generally attached to the body-facing surface 48 of the shell 29. The attachment may be in a permanent manner, meaning that the absorbent component 40 is generally intended not to be removable by the wearer of the article 20. Alternatively, the absorbent component 40 may be constructed to be removable by the wearer, meaning that the absorbent component 40 may be removed and replaced with another absorbent component 40 by the wearer of the article 20, or be replaced with nothing at all. In some aspects, when the absorbent component 40 is attached to the shell 29 in a permanent manner, meaning that the absorbent component 40 is not intended to be removed by the wearer, various bonding means can be used, such as a construction adhesive for example. Examples of useable construction adhesives include any adhesive which will effectively hold the absorbent component 40 in place, so as not to be separated from the shell 29. Commercially available construction adhesives usable in the present invention include, for example, Rextac™ adhesives available from Huntsman Polymers, Houston, Tex. Other means may be used to hold the absorbent component 40 to the shell 29 including bonding techniques known in the art, including, but not limited to, adhesive bonds, cohesive bonds, thermal bonds, ultrasonic bonds, embossing, crimping, entangling, fusing, hook and loop, or the like, and combinations thereof.
Where the absorbent component 40 is preferably removably attached, the absorbent component 40 is held in place on the shell 29 by a means which will allow the wearer to remove the absorbent component 40. One such means of holding the absorbent component 40 is by using a pressure sensitive adhesive. Suitable pressure sensitive adhesives include, but are not limited to, any commercially available pressure sensitive adhesive. Examples of suitable pressure sensitive adhesives usable to removably hold the absorbent article 40 in place on the shell 29 include pressure sensitive adhesives available from National Starch, Bridgewater, N.J.
In certain embodiments it may be advantageous for the absorbent component 40 to have a backsheet 42 and more preferably a fluid impervious backsheet. The backsheet can serve to provide liquid impermeability for the absorbent component 40, such that any fluids entering the absorbent component 40 will not flow through the structure to the clothing of a wearer. One example of a commercially available fluid impervious backsheet is the XP-3473a baffle available from Huntsman Packaging Corporation, Houston, Tex.
The absorbent component 40 may include one or more wicking layers. For example, the absorbent component 40 may include wicking layers 43a and 43b, which may be formed from meltblown microfiber such as the 50 gsm meltblown fibers commercially available from Yuhan-Kimberly Ltd., Korea. The absorbent component 40 may further comprise an absorbent layer 44, intake layer 45 and topsheet 46. The absorbent layer 44 may contain one or more layers of absorbent materials, such as fibrous materials and/or superabsorbent materials for example. Each of the layers can contain similar materials or different materials. Materials that can be used to form the absorbent layer 44 include those materials conventionally used in absorbent articles and includes materials, such as, for example, cellulose, wood pulp fluff, rayon, cotton, and meltblown polymers such as polyester, polypropylene or coform. Coform is a meltblown air-formed combination of meltblown polymers, such as polypropylene, and absorbent staple fibers, such as cellulose. A desired material is wood pulp fluff, for it is low in cost, relatively easy to form, and has good absorbency.
Topsheet 46 should be able to manage different body excretions depending on the type of product. In feminine care products, often the body-side liner or topsheet 46 must be able to handle menses and urine. In certain embodiments the topsheet 46 may include a layer constructed of any operative material and may be a composite material. For example, the body-side liner or body-contacting layer can include a woven fabric, a nonwoven fabric, a polymer film, a film-nonwoven fabric laminate or the like, as well as combinations thereof.
The backsheet 42 may be fluid impermeable or fluid pervious. The back sheet 42 may, for example, include a polymeric film, a woven fabric, a nonwoven fabric or the like, as well as combinations or composites thereof. For example, the backsheet 42 may include a polymer film laminated to a woven or nonwoven fabric. In a particular feature, the polymer film can be composed of polyethylene, polypropylene, polyester or the like, as well as combinations thereof. Construction adhesive 33 is applied to backsheet 42 and the topsheet 46. Absorbent component 40 is sandwiched between and laminated to back sheet 42 and topsheet 46.
The shell 29 can include a polymeric film, a woven fabric, a nonwoven fabric, a foam or the like, as well as combinations or composites thereof. In some aspects, shell 29 may include a laminate structure, such as a polymer film laminated to a woven or nonwoven fabric. In some embodiments, the shell 29 may be a composite material made of two or more separate pieces of material joined together in the longitudinal direction 14 and/or the lateral direction 16 to create the whole. In an alternate embodiment, not shown, the absorbent article may include a shell that consists of 2-5 separated materials that are seamed and/or bonded together to make one continuous shell layer of the absorbent article. In other embodiments, the shell 29 may be a single whole material extending in the longitudinal direction 14 and/or the lateral direction 16.
In some embodiments, the shell 29 is corona treated to improve its adhesion properties. Alternately the shell 29 can be pre-corona treated. In some embodiments, the shell 29 may be a nonwoven web of fibrous material such as, for example, a spunbond web, a meltblown web, bonded carded web, or a combination thereof. The material may be made of an elastomeric fiber forming polymer. A meltblown web used in this invention may initially be produced using conventional meltblowing processes and apparatus as known in the art whereby a cohesive web is formed. A nonwoven composite web used in this invention may initially be formed by techniques also well known in the art and described in U.S. Publication No. 2008/0095978. The composition of the body adhering shell 29 may be a stretchable laminate of a woven or nonwoven fabric with a silicone polymer, wherein the silicone polymer has adhesive properties. In this aspect, the garment-facing surface of the shell can be the woven or nonwoven fabric and the body-facing surface of the shell can include the silicone polymer. Other suitable materials and methods of manufacturing the body-adhering absorbent articles of the present invention are disclosed in U.S. patent application Ser. No. 13/022,706 and Ser. No. 13/022,700, filed on Feb. 8, 2011, the entirety of both are incorporated herein by reference where not contradictory.
In some embodiments, portions of the shell 29 may be deadened. Deadening refers to the process by which the extension, retraction or elastic properties of a web are reduced or eliminated by, for example, bonding, the application of heat, adhesive or a patch of inelastic material, or combinations thereof. Bonding means may include, but are not limited to pressure bonding, ultrasonic bonding, adhesive bonding, thermal bonding, or the like. In some embodiments, various regions are deadened by forming bond lines in one or more selected regions of the stretchable nonwoven web or laminate material in one or more selected directions, whereby the stretchability in the selected direction of the material can be controlled and substantially reduced in the region(s) of the bond lines.
In some embodiments, components such as an adhesive transfer layer 32 or an absorbent component 40 are attached to the deadened regions of the shell 29. The components may be attached using any method known in the art, for example, pressure bonding, adhesive bonding, thermal bonding and ultrasonic welding.
In some embodiments, the anterior separation zone 24 and/or the posterior separation zone 28 may be devoid of absorbent material and/or may be devoid of body adhesive. Referring now to

In some embodiments, only the anterior attachment region of the various absorbent articles may include any of the donning systems disclosed herein. Likewise, in some embodiments, only the posterior attachment region of the various absorbent articles may include any of the donning systems disclosed herein. In some embodiments, both the anterior attachment region and the posterior attachment region may include any of the donning systems disclosed herein. In some embodiments, the anterior attachment region and the posterior attachment region may have any of the donning systems disclosed herein and may have the same donning system. In other embodiments, the anterior attachment region and the posterior attachment region may have any of the donning systems disclosed herein and may have different donning systems.
The product configurations and donning systems disclosed herein are believed to minimize contamination of the body adhesive by providing two distinct grasping surfaces that can be utilized during the attachment process. In addition, these product configurations and donning systems are believed to reduce errant attachment and adhesive fold over by reducing the amount of exposed adhesive during the donning process. Finally, these product configurations and donning systems allow stretching of the absorbent article while the absorbent article is at least partially attached to the body. For example, in some embodiments, the peel strip is an inelastic material and thus inhibits the attachment region from stretching during application which in turn improves the wearer's comfort and the ability of the attachment region to move and stretch with the wearer.
While the invention has been described in detail with respect to specific embodiments thereof, it will be appreciated that those skilled in the art, upon attaining understanding of the foregoing, will readily appreciate alterations to, variations of, and equivalents to these embodiments. Accordingly, the scope of the present invention should be assessed as that of the appended claims and any equivalents thereto. Additionally, all combinations and/or sub-combinations of the disclosed embodiments, ranges, examples, and alternatives are also contemplated.
This application is a divisional of application Ser. No. 13/224,523, entitled “BODY ATTACHED ABSORBENT ARTICLE DONNING SYSTEM” and filed in the U.S. Patent and Trademark Office on Sep. 2, 2011. The entirety of the prior application is hereby incorporated by reference in this application.
