• absorbent article refers to articles which absorb and contain body exudates and more specifically refers to articles which are placed against or in proximity to the body of the wearer to absorb and contain various exudates discharged from the body.
• Absorbent articles are typically differentiated by whether they are reusable or disposable.
• Disposable refers to articles which are generally intended to be discarded after a single use (i.e., they are not generally intended to be laundered or otherwise restored or reused).
• the absorbent articles of the present invention are preferably disposable absorbent articles.
• the absorbent articles may be further defined by whether they are "unitary” such that they do not require a separate manipulative parts or whether they comprise an element of a diaper system such as a separate holder and liner.
• the absorbent articles of the present invention are preferably unitary.
• a unitary disposable absorbent article of the present invention, diaper 20, is shown in FIG. 1.
• the term "diaper” refers to a garment generally worn by infants and/or incontinent persons about the lower torso to receive and contain bodily exudates. It should be understood, however, that the present invention is also applicable to other disposable absorbent articles such as incontinence briefs, undergarment absorbent inserts, disposable training pants, belted diapers, diaper holders, sanitary napkins and the like, as well as articles of clothing or other articles to be fitted to wearers.
• FIG. 1 is a plan view of one embodiment of a diaper 20 in its flat out, uncontracted state (i.e., without any elastic induced contraction pulled out) with portions of the structure being cut away to more clearly show the underlying structure of the diaper 20 and with the portion of the diaper 20 which contacts the wearer facing away from the viewer.
• the diaper 20 is shown to have a front waist region 36, a rear waist region 38, and a crotch region 37 located between the front waist region 36 and the rear waist region 38.
• the waist regions generally comprise those portions of the diaper 20 which, when worn, encircle the waist of the wearer.
• the waist regions may include an elastic element or other means for gathering or for permitting extension about the waist of the wearer to improve fit and containment.
• the crotch region 37 is that portion of the diaper 20 positioned between the front waist region 36 and the rear waist region 38 which, when the diaper 20 is worn, is generally positioned between the legs of the wearer.
• the diaper 20 preferably comprises a liquid pervious topsheet 22, a liquid impervious backsheet 24 and an absorbent core 26 which is preferably located between the topsheet 22 and the backsheet 24.
• the absorbent core 26 preferably has a garment surface which generally faces away from the wearer and a body surface which generally faces the wearer.
• the diaper 20 preferably also includes at least one finger pocket 50 which may be used to help fit the diaper 20 to the wearer.
• the diaper 20 may also include such other features as are known in the art including leg cuffs 28, front and rear ear panels 30, waist features 32, elastics and the like to provide better fit, containment and aesthetic characteristics. Such additional features are well known in the art and are described in U.S. Pat. No.
• the backsheet 24 extends beyond the edges of the absorbent core 26 to thereby form the periphery of the absorbent article.
• the periphery defines the outer perimeter, in other words, the edges of the diaper 20.
• the periphery comprises the longitudinal edges 42 and the end edges 44.
• the topsheet 22 may be coterminous with the backsheet 24 along the end edges 44 as well as the longitudinal edges 42 of the diaper 20.
• the absorbent core 26 may be any absorbent material which is generally compressible, conformable, non-irritating to, the wearer's skin, and capable of absorbing and retaining liquids and certain body exudates.
• the absorbent core 26 may be manufactured in a wide variety of sizes and shapes (e.g., rectangular, hour-glass, asymmetric, etc.) and from a wide variety of liquid absorbent materials commonly used in disposable diapers and other absorbent articles, such as comminuted wood pulp, which is generally referred to as airfelt.
• suitable absorbent materials include creped cellulose wadding, absorbent foams, absorbent sponges, superabsorbent polymers, absorbent gelling materials, or any equivalent materials or combination of materials.
• the total absorbent capacity of the absorbent core 26 should be compatible with the intended use of the diaper 20. Further, the absorbent capacity and configuration of the absorbent core 26 may be varied to accommodate wearers ranging from infants through adults (e.g., the absorbent core may have a varying caliper, or hydrophilic gradient, a capillary differential, low density zones, or may or may not contain absorbent gelling materials).
• the absorbent core 26 may comprise a layer of absorbent material comprising hydrophilic fibers and particles of absorbent gelling material (hydrogel) such as the absorbent structure described in U.S. Patent 4,610,678 entitled “High-Density Absorbent Structure” which issued to Paul T. Weisman and Steven A. Goldman on September 9, 1986 and which patent is incorporated herein by reference.
• Preferred embodiments of the absorbent core 26 are generally described in U.S. Patent No. 5,234,423 entitled “Absorbent Article With Elastic Waist Feature and Enhanced Absorbency", issued to Alemany et al. on August 10, 1993; and U.S. Patent No.
• the topsheet 22 is preferably compliant, soft feeling, and non-irritating to the wearer's skin. Further, the topsheet 22 is preferably liquid pervious permitting liquids to readily penetrate through its thickness.
• a suitable topsheet 22 may be manufactured from a wide range of materials, such as porous foams, reticulated foams, formed films, apertured plastic films, natural fibers (e.g., wood or cotton fibers), synthetic fibers (e.g., polyester or polypropylene fibers) or from a combination of natural and synthetic fibers. There are a number of manufacturing techniques which may be used to manufacture the topsheet 22. For example, the topsheet 22 may be woven, non- woven, spunbonded, carded, or the like.
• One preferred topsheet 22 comprises polypropylene fibers having a denier of about 2.2, such as P-8, manufactured by Veratec, Inc., a Division of the International Paper Company, of Walpole, Massachusetts.
• a preferred topsheet 22 is carded, and thermally bonded by means well known to those skilled in the fabrics art.
• the topsheet 22 is made of a hydrophobic material to isolate the wearer's skin from liquids in the absorbent core 26. If the topsheet 22 is made of a hydrophobic material, at least the upper surface of the topsheet 22 is treated to be hydrophilic so that liquids will transfer through the topsheet 22 more rapidly. This diminishes the likelihood that body exudates will flow off the topsheet 22 rather than being drawn through the topsheet 22 and being absorbed by the absorbent core 26.
• the topsheet 22 can be rendered hydrophilic by treating it with a surfactant including spraying the topsheet 22 material with a surfactant or immersing the material into the surfactant. A more detailed discussion of such a treatment is contained in U.S.
• topsheet 22 and the backsheet 24 may be joined together in any suitable manner as is well known in the diaper manufacturing art.
• the term "joined” encompasses configurations whereby elements of the diaper 20 are connected to each other either directly or indirectly.
• the topsheet 22 may be directly joined to the backsheet 24 by affixing the topsheet 22 to the backsheet 24 itself or may be indirectly joined to the backsheet 24 by affixing the topsheet 22 to intermediate members which in turn are affixed to the backsheet 24.
• the topsheet 22 and the backsheet 24 are joined directly to each other in the diaper periphery by an adhesive or any other attachment means as is known in the art. Alternative suitable attachment means are discussed below with regard to the backsheet 24.
• the backsheet 24 is preferably positioned adjacent the garment surface of the absorbent core 26 that faces away from the wearer and is preferably secured thereto by attachment means such as those well known in the art.
• the backsheet 24 may be secured to the absorbent core 26 by a uniform continuous layer of adhesive, a patterned layer of adhesive, or an array of separate lines or spots of adhesive.
• the attachment means may comprise heat bonds, pressure bonds, ultrasonic bonds, dynamic mechanical bonds, or any other suitable attachment means or combinations of these attachment means as are known in the art.
• An adhesive which has been found to be satisfactory is manufactured by H. B. Fuller Company of St. Paul Minn, and marketed as HL-1258.
• the core attachment means preferably comprise an open pattern network of filaments of adhesive as is shown in U.S.
• Patent 4,573,986 entitled "Disposable Waste-Containment Garment" which issued to J. A. Minetola and David R. Tucker on March 4, 1986, and which is incorporated herein by reference.
• An exemplary attachment means of an open pattern network of filaments comprises several lines of adhesive filaments swirled into a pattern such as is illustrated by the apparatus and methods shown in U.S. Patent No. 3,911,173 issued to Sprague, Jr. on Oct. 7, 1975; U.S. Patent No. 4,785,996 issued to Zieckler, et al. on Nov. 22, 1978; and U.S. Patent No. 4,842,666 issued to Werenicz on June 27, 1989. Each of these patents are incorporated herein by reference.
