Description

ABSORBENT ARTICLE WITH SMOOTHING AGENTS OF THE ODOR RELEASED THROUGH THE CLAMPING SYSTEM FIELD OF THE INVENTION The present invention relates to an absorbent article which comprises a fastening system containing encapsulated agents that mask the bad odor, such that upon removal of the user's article, the odor masking agents are released to disguise. cover up the odors of the exudate.

BACKGROUND OF THE INVENTION A wide variety of fluid-absorbing structures known in the art absorb body fluids such as blood, urine, menstruation and the like, and are of sanitary and comfortable use. Disposable products of this type generally comprise a fluid-permeable top sheet material, a fluid absorbent core, and a fluid-impermeable backsheet material. Various shapes, sizes and thicknesses of these items have been explored in an attempt to make their use more comfortable and convenient. Odor control in medical devices has been under investigation for many years. Many of the body fluids have an unpleasant odor or develop odors when they come in contact with air and / or bacteria for prolonged periods. Several odor controlling agents have been reported in the literature. For example, U.S. Patent No. 4,525,410, Hagiwara et al., Issued June 25, 1985, teaches zeolite particles (stimulated with bactericidal cations) stably maintained in a fibrous web by incorporating some parts of fusible fibers into the plot, and apply heat. Hagiwara et al. Teaches the use of these compositions as an outer covering layer in general sanitary articles.

U.S. Patent No. 2,690,415, FA Shuler, issued September 28, 1954, teaches that particles of odor-absorbing materials uniformly fixed in the interstices of a permeable web by an adhesive provide an odor-absorbing medium. , for example, catamenial products. It highlights the carbon, silica gel and alumina activated in particles. The deviation and / or displacement of the particles is avoided and the sheet is flexible. ABSCENTS (for odor control) for use in diapers and catamenial products are specifically highlighted in the Union Carbide booklet (A. J. Gioffre 1988). The brochure indicates that Union Carbide commercial research shows potential benefits in these products. U.S. Patent Nos. 4,795,482 and 4,826,497, related to ABSCENTS used as an agent for odor control, generally, in medical devices, in particular. Activated carbon is a very effective odor absorber, with an average internal surface area of approximately 1000 m2 / g. However, activated carbon is not easily incorporated into consumer products. The zeolites have a smaller surface area on the scale of approximately 400-800 m2 / g. However, zeolites can absorb moisture from body fluids (ie, water) over other fluids, which can compromise their effectiveness. In addition, activated carbon and zeolites have open structures, and continuously absorb organic vapor carried by the air, unless it is hermetically sealed. Therefore, during storage, these odor absorbers may become saturated and less efficient before the products are used. Consumers are accustomed to the fact that the bad smell of the body determines the need to change a diaper, catamenial and similar product. Therefore, using odor masking agents or encapsulated in a core of the absorbent article, the topsheet or the backsheet, would hamper the consumer's ability to properly judge the removal time of the article. For example, since the consumer's sensitivity to a masking fragrance would decrease as it is released within an article, the perception of the moment of removing a diaper or the catamenial product would also decrease. Consumers do not want to be exposed to bad body odor, but it is not preferable to mask these odors while the absorbent article is in use. Therefore, the applicant's invention allows the consumer to mask the bad smell of the body by removing the user's item.Lu.

An alternate embodiment is one as in Figure 2 wherein the securing tab 42 does not contain microcapsules 70; in this manner, the end portions 66 and the secondary areas 75 only contain adhesive. The encapsulation zone 75 then becomes the secondary zone 75 when this zone does not contain microcapsules 70. In such a construction, the perfume-filled microcapsules are embedded on the second holding member 41. Figure 3 discloses another embodiment of the securing system. 40. Disclosed here is the combination of adhesive and hook fastening tab 42, wherein the end portions 66 of the tabs 42 only contain adhesive. The encapsulated zone 75 (or secondary) comprises the hooks 63 that will engage the curls 61 of the second holding member 41. The perfume-filled microcapsules 70 can be fixed directly to the hooks 63. Also, the microcapsules 70 can be embedded within the the secondary zones 75 by a securing means 90 (figures 6A and 6B) at or near the attachment points of the hooks 63 to the tabs 42, ie, secured to the surface of the area 75. As discussed, a The fastening system of the present invention comprises hook and loop type fasteners. As used herein, the term "hook-and-loop fasteners" refers to the fastening means comprising a "hook" component (hereinafter also referred to as a coupling component) and a complementary loop component ( hereinafter also referred to as a "Mooring Component"). The term "Hook" is used to designate a material that has coupling elements. In this way, the hook fastening material can also be referred to as a male fastener. It should also be understood that the use of the term "Hook" should not be limiting in the sense that the coupling elements may comprise any of the forms as known in the art as long as they are adapted to engage a complementary mooring component. Figure 4 discloses another embodiment of the fastening system 40 of the present invention. Disclosed herein is the combination of adhesive and hook fastening tabs 42, wherein the end portions 66 of the tabs 42 comprise the hooks 63. In addition, the microcapsules 70 are embedded at least partially in and / or within the portions of end 66 preferably by securing means 90 (Figures 6A and 6B), although any securing means known in the art that are compatible for use in a diaper 20 will suffice. The preferred embodiment in Figure 4 contains microcapsules filled with perfume 70. Alternative embodiments are contemplated having tabs 42, which have no microcapsules 70 embedded within the end portions 66, and microcapsules 70 only embedded in the encapsulated area 75 which I would not understand any of the hooks. Preferably, the encapsulated zone 75 would comprise a layer of adhesive. Specifically, according to the present invention, the securing means 90 of the securing tabs 42, whose surface is in contact with the second clamping member 41, is provided with the multiplicity of small frangible microcapsules 70 containing perfume 95. Figures 6A and 6B illustrate this securing means 90 containing perfume-filled microcapsules 70. Various methods can be used to adhere the microcapsules to the securing means 90 of the securing tabs 42 and / or to the second securing member 41. Preferably, a plurality of microcapsules dispersed in an adhesive may form the securing means 90 of the holding tabs 42 and / or the second holding member 41. A wide variety of adhesives will be suitable for this purpose, such as, for example, polyethylenes, polyesters , polysiloxanes, acrylics, or copolymers of distillate block.

Figure 6A discloses the side view of the hooks 63 with the microcapsules 70 embedded at least partially within a securing means 90. Preferably, the microcapsules 70 are embedded within an assurance means 90 that comprises adhesive and are attached to the member of clamping to form the micromicrocapsulation zone 75. Alternatively, the microcapsules 70 can be attached directly to the hooks 63. Figure 6B discloses the side view of the curls 61 with microcapsules 70 embedded at least partially within the securing means 90. and preferably adhesively securing at points below the curl ends or connection 51 of the curls 61. Preferably, the microcapsules 70 are partially embedded within the securing means 90 such that a surface of the microcapsules 70 is free to allow contact with a shear medium such as a tape tab, while s that the remaining portions of the microcapsules 70 are fixed to the surface of the encapsulation zone 75, to assist the effective shear of the microcapsules 70. Preferably, at least 10 percent of the surface area of the microcapsules 70 will be secured and / or protected by an assurance means 90 to assist effective shear stress. Figure 5 discloses a second preferred clamping member 41 that can be used with the clamping tabs 42. With this second clamping member 41, the clamping tabs 42 may either contain no microcapsules 70 or may contain microcapsules 70 in the area encapsulated 75 (or secondary). As disclosed, the microcapsules 70 can substantially cover the second holding member 41 in a predetermined configuration. However, the number of capsules present in the second clamping member 41 can vary from one to a number desired by a manufacturer. Also, any configuration of the microcapsules 70 can be provided in the second clamping member 41 desired by a manufacturer.

Figure 5A discloses a second clamping member 41 divided in the curl regions 81 at the left and right ends of the second clamping member 41 and a receiving area 82 of the clamping tab centrally positioned in the second clamping member 41. microcapsules 70 are embedded or placed within the curl zone 81 preferably by an adhesive, but any securing means known in the art that is compatible for use in a diaper 20 will suffice. Another embodiment is a second clamping member 41, wherein the microcapsules are embedded within the curl region 81 and secured on the receiving zone 182 by the securing means, preferably being adhesive. Also, alternatively, there is a second clamping member 41 containing microcapsules 70 embedded within the receiving zone 82 of the tape only. Figure 5B discloses a second preferred clamping member 41 for the preferred combination of tape and width retaining tabs 42 disclosed in Figure 4. The curl zone 81 is centrally positioned on the second clamping member 41 to receive the hooks 63 in the end portions 66 of the tabs 42 as shown in Figure 4. In this embodiment, the microcapsules 70 are embedded within the loop region 81 preferably by an adhesive securing means. In alternate embodiments of Fig. 5B, the microcapsules 70 can be placed both in the receiving regions of 182 and the curl zone 81, thereby providing the microcapsules 70 substantially along the total surface of the second holding member 41. Alternatively, the microcapsules 70 can be placed in the receiving area of 182 only and not in the hook area 81. In an alternate embodiment for all the second clamping members 41 disclosed, none of the microcapsules 70 would be embedded within the second clamping member 41, thereby causing the tape and the hook tabs 76 to contain all of the microcapsules 70 that are exploded upon disengagement of the clamping system 40. Figure 7 shows a the microcapsules 70 substantially embedded within the adhesive securing means 90. The securing means 90 makes contact with the securing tab 42 and the second securing means 41. Figure 7 shows a side-by-side arrangement of two types of microcapsules, but it would be obvious to anyone skilled in the art that any physical arrangement of the microcapsules that produce the desired fragrance discharge and / or diffusion perfume release can be used. Also, more than two types of microcapsules can be used to produce the desired fragrance characteristics; for example, a type of microcapsules that produces a fragrance discharge upon the shear stress of the microcapsules and another type of microcapsules that diffuses perfume when the fastening system 40 disengages. Figure 7A describes a side view in approach of the interlock of a fastening tape tab 42 and the second fastening member 41 having microcapsule 70 therebetween during the action of disengaging the fastening system 40. On disengagement a fastener 40 is applied. force of shear to the microcapsules 70, which causes a shearing or tearing of at least the upper parts and / or the uninsured portions of the microcapsules 70, thereby relieving the perfume 95 thereof. Figure 7A schematically illustrates a mechanism that is believed to be operative to ensure that a quantity of controlled perfume 95 is released from the microcapsules 70 during use. Referring to the non-detached portion 103 of the holding tab 42, it can be seen that a portion of at least some of the microcapsules 70 are at least partially embedded within a layer of adhesive 90 when the securing tab 42 is applied to your fastening position before use. Referring now to the detached portion 102 of the securing tab 42, it can be seen that the effects of detaching the securing tab 42 causes a shearing stress through the upper parts of the microcapsules 70 and facilitates their breaking, freeing from this Perfume 95. Those factors that control the number of broken microcapsules 70 and consequently the amount of fragrance 95 released, can be totally within the control of the discretion of the manufacturer through the manipulation of these parameters such as the size of the microcapsule. and the thickness of the wall, the type of securing means used, the amount of securing means used, the amount and type of perfume used, the resistance to rupture of the microcapsules, the number and distribution of the microcapsules, the strength of the adhesive of an adhesive in relation to the breaking strength of the microcapsules, and other of these factors that may affect the breakdown of the microcapsule. In one example, it is believed that both the force required to pull a microcapsule from the adhesive or from a second clamping member would be greater than the force required to break a microcapsule. If this condition satisfies, the microcapsules embedded within an adhesive break. In another example, the microcapsules 70 sized at 50 microns or above, would be easily burst when separating those from the holding tongues 42 of the second clamping member 41 because of the increased effects of the adhesive and cohesive properties of the materials in contact with the microcapsules 70. Examples of suitable tape adhesive tongue fastening systems are disclosed in U.S. Patent No. 3,848,594 issued to Buell on November 19, 1974; and in U.S. Patent No. 4,662,875 issued to Hirotsu and Robertson on May 5, 1987; each of which is incorporated herein by reference.

When a two-point fastening system is used, the waist closure members of the waist closure system are preferably aligned longitudinally with the front extension waist feature 42 and laterally aligned with the elastic filaments of the extension leg cuffs 30 for Provide an effective closure around both legs and waist. As shown in all the disclosure, the diaper 20 can be provided with a pair of fastening tabs 42 that allows the side panels to be first joined together. The diapering person then places the containment assembly 22 between the user's legs and attaches assembly 22 to the outer layer of the waist feature. This configuration and assurance method is more fully described in the aforementioned US patent application serial numbers 08 / 044,562 (New, and others).

Goulait on July 5, 1994, which is incorporated herein by reference herein. Still other suitable second fastening components are disclosed in co-pending U.S. patent application serial number 08 / 254,814 entitled "Non-woven female component for restrainable fastening devices and method for making the same" filed June 6, 1994. on behalf of Patrick Jay Allen and others; U.S. Patent Serial No. 08 / 287,571 entitled "Nonwoven Female Component for Restrainable Clamping Device" filed August 9, 1994 in the name of Willie F. King et al .; and U.S. Patent Application Serial No. 08 / 374,269 entitled "Female Component for Restrainable Clamping Device" filed January 18, 1995 in the name of Carl L. Bergman et al. The fastening elements can be arranged on either the external surface or the inner surface of the diaper 20. However, in a preferred embodiment, the fastening elements are disposed on the diaper 20 in such a way that the fasteners do not irritate the skin of the diaper 20. user. In addition, the fastening elements may either be a separate discrete element fixed to the diaper 20 or a unitary piece of material that is not divided or discontinuous with a diaper member 20 such as the topsheet 24 or the backsheet 26 Although the fasteners may assume varying sizes and shapes, they preferably comprise one or more separate patches of material attached to the diaper 20 to allow for the best fit for a wide range of users. The topsheet 24 is positioned adjacent to the body surface of the absorbent core 28, and is preferably attached to it and to the backsheet 26 by attachment means (not shown) such as those well known in the art. Suitable attachment means are described with respect to attachment of the backsheet 26 to the absorbent core 28. As used herein, the term "joined" encompasses configurations with which one element is directly secured to the other element by directly fixing the element to the other element, and configurations with which the element is indirectly secured to the other element by fixing the element to a member or members intermediate ones that in turn are fixed to the other element. In a preferred embodiment of the present invention, the topsheet 24 and the backsheet 26 are directly bonded together at the periphery of the diaper and are indirectly joined together by attaching them directly to the absorbent core 28 by the attachment means (not shown). The topsheet 24 is preferably docile, of soft feel and non-irritating to the wearer's skin. In addition, the topsheet 24 is preferably liquid permeable, allowing liquids (eg, urine) to easily penetrate through its thickness. A suitable top sheet can be manufactured from a wide range of materials, such as porous foams; cross-linked foams; plastic films with openings; or woven or nonwoven webs of natural fibers (e.g., wood or cotton fibers), synthetic fibers (e.g., polyester or polypropylene fibers), or a combination of natural and synthetic fibers. The topsheet 24 is preferably made of a hydrophobic material to isolate the wearer's skin from the liquids that have passed through the topsheet 24, and are contained within the absorbent core 28 (i.e., prevent rewetting). If the top sheet is made of a hydrophobic material, at least the top surface of the top sheet is treated so that it is hydrophilic in such a way that liquids will transfer through the top sheet more quickly. This decreases the likelihood that the body exudates will flow out of the top sheet instead of being drawn through the top sheet and absorbed by the absorbent core. The top sheet can be made hydrophilic by treating it with a surfactant. Suitable methods for treating the topsheet with a surfactant include spraying the topsheet with a surfactant and immersing the material within the surfactant. A more detailed discussion of this treatment and the hydrophilic capacity is contained in U.S. Patent Nos. 4,988,344 entitled "Absorbent articles with multi-layer absorbent layers" issued to Reising, and others on January 29, 1991. There is a number of manufacturing techniques that can be used to manufacture the topsheet 24. For example, the topsheet 24 can be a non-woven web of fibers. When the upper sheet comprises a non-woven web, the web may be bonded, carded, wet-laid, melt-blown, hydroentangled, combinations of the above or the like. A suitable top sheet is carded and thermally bonded by means well known to those skilled in the art. A satisfactory top sheet comprises short length polypropylene fibers having a denieble approximately 2.2. As used herein the term "short-length fibers" refers to those fibers that have a length of at least about 15.9 millimeters. Preferably, the top sheet has a basis weight of about 18 to approximately 25 grams per square meter. A suitable top sheet is manufactured by Veratec, Inc., a division of International Paper Company, of Walpole, Mass, under the designation P-8. The backsheet 26 is positioned adjacent the garment surface of the absorbent core 28 and is preferably attached to it by means of bonding (not shown) such as those well known in the art. For example, the backsheet 26 can be secured to the absorbent core 28 by a uniform, continuous adhesive layer, a patterned adhesive layer, or an array of separate lines, splines or dots of adhesives. Adhesives that have been found to be satisfactory are manufactured by H. B. Fuller Company of St. Paul, Minnesota, marketed as HL-1258. The attachment means will preferably comprise an open-pattern network of filaments of adhesive as disclosed in U.S. Patent No. 4,573,986 entitled "Disposable Containment Garment," which was issued to Minetola and Tucker on March 4. 1986, and which is incorporated herein by reference. An exemplary joining means of an open filament web network comprises several lines of adhesive filaments twisted in a spiral pattern illustrated by the apparatus and methods shown in United States Patent No. 3,911,173 issued to Sprague, Jr. on October 7, 1975; U.S. Patent No. 4,785,996 issued to Ziecker et al. on November 22, 1978; and U.S. Patent No. 4,842,666 issued to Werenicz on June 27, 1989. Each of these patents is incorporated herein by reference. Alternatively, the joining means may comprise heat junctions, pressure joints, heat / pressure junctions, ultrasonic junctions, dynamic-mechanical junctions, or any other suitable joining means or combinations of these joining means as are known in the art. technique. The backsheet 26 is preferably impervious to liquids (eg, urine) and is preferably fabricated from a thin plastic film, although other flexible fluid impervious materials may also be used. As used herein, the term "flexible" refers to materials that are docile and readily conform to the shape and general contour of the human body. The backsheet 26 prevents the exudates absorbed and contained within the absorbent core 28 from wetting the articles that come into contact with the diaper 20 such as sheets and undergarments. In this manner, the backsheet 26 may comprise a woven or non-woven material, polymeric films such as polyethylene or polypropylene thermoplastic films, or composite materials such as a film-coated nonwoven material. Preferably, the backsheet is a thermoplastic film having a thickness of from about 0.012 millimeters to about 0.051 millimeters. The backsheet preferably comprises a smooth polyethylene film of approximately 0.025 mm as manufactured by Tredegar Corporation of Terre Haute, IN, and marketed as P8863. The absorbent core 28 may be any absorbent member that is capable of absorbing and retaining liquids such as urine and certain other exudates from the body. The absorbent core 28 has a garment surface, a body surface, side edges and waist edges. The absorbent core 28 can be manufactured in a wide variety of sizes and shapes (eg, rectangular, hourglass, asymmetric, etc.) and from a wide variety of liquid absorbent materials commonly used in disposable diapers and other absorbent articles, such as crushed wood pulp which is generally referred to as an air filter. Examples of other suitable absorbent materials include creped cellulose wadding; melt blown polymers including coform; chemically modified or cross-linked cellulose fibers, chemically hardened; tissue including tissue wraps and tissue sheets; absorbent foams; absorbent sponges; super absorbent polymers; gelling absorbent materials; or any equivalent material or combinations of materials. The configuration and construction of the absorbent core can also be varied (e.g., the absorbent core can have zones of varying gauge, a hydrophilic gradient, a super-absorbent gradient, or areas of acquisition of lower average basis weight and lower average density; may comprise one or more layers or structures). However, the total absorbent capacity of the absorbent core 28 must be compatible with the design load and intended use of diaper 20. In addition, the size and absorbent capacity of the absorbent core 28 can also be varied to encompass users ranging from baby to adults. Figure 1 shows a preferred embodiment of the diaper 20 having an absorbent core with a rectangular shape. A useful absorbent structure such as the absorbent core 28 of the present invention which have achieved wide acceptance and commercial success, are described in U.S. Patent No. 4,610,678 entitled "High Density Absorbent Structure" issued to Weisman and Goldman on 9 September 1986; U.S. Patent No. 4,673,402 entitled "Absorbent articles with cores with double layers" issued to Weisman, Houghton and Gellert on June 16, 1987; United States Patent No. 4,888,231 entitled "Absorbent Core Having a Dust Cap" issued to Angstadt on December 19, 1989; U.S. Patent No. 5,147,345 entitled "High Efficiency Absorbent Articles for Incontinence Management", issued to Young, LaVon and Taylor on September 14, 1992; U.S. Patent No. 5,102,597 entitled "Porous, absorbent, polymeric macrostructures, and methods for making them", issued to Roe, Lahrman and Berg on April 7, 1992; and U.S. Patent No. 4,834,735 entitled "High density absorbent members having acquisition zones of lower density and lower basis weight" issued to Alemany and Berg on May 30, 1989; they also describe absorbent structures that are useful in the present invention. The absorbent core is preferably the double-layer absorbent structure described in U.S. Patent No. 5,234,423 entitled "Absorbent Article with Deithelial Characteristic and Increased Absorbency" issued to Alemany and Clear on August 10, 1993. In a preferred embodiment of In the present invention, an acquisition layer or layers can be placed between the topsheet 24 and the absorbent core 28, and attached to the absorbent core. The acquisition layer can serve several functions including improving the capillary action of the exudates on and towards the absorbent core. There are several reasons why the improved capillary action of exudates is important, including providing a more even distribution of the exudates throughout the absorbent core 28 and allowing the absorbent structure to be made relatively thin. The capillary action or wicking effect referred to herein may encompass the transportation of liquid in one, in two or in all directions (ie, in the x-y plane and / or in the z-direction). The acquisition layer may be composed of several different materials, including non-woven or woven webs of synthetic fibers including polyester, polypropylene or polyethylene, natural fibers including cotton or cellulose, mixtures of these fibers, or any equivalent materials or combinations of materials . Examples of the absorbent structures disclosed herein having an acquisition layer and a topsheet are more fully described in U.S. Patent No. 4,950,264 issued to Osborn and in U.S. Patent Application Serial No. 07 / 944,764, "Absorbent article having fused layers", filed on October 7, 1992 in the name of Cree et al. Each of these references are incorporated herein by reference. In a preferred embodiment, the acquisition layer may be bonded to the topsheet 24 and separated from inserted absorbent material or absorbent core 28, by any of the conventional means for joining wefts together, most preferably by fusion bonds as described more fully in the Cree application referred to above. The diaper 20 preferably further comprises elastic leg cuffs 30 to provide improved containment of liquids and other exudates from the body. Each elasticized leg fold 30 can comprise several different modalities to reduce leakage of body exudates in the leg regions. (The leg fold can be and is sometimes also referred to as leg bands, side flaps, barrier folds or elastic folds). U.S. Patent No. 3,860,003 entitled "Shrinkable side portions for a disposable diaper" issued to Buell on January 14, 1975, discloses a disposable diaper that provides a collapsible leg opening having a side flap and one or more members elastics to provide an elasticated leg fold (packing fold). The patent of the United States No. 4,909,803 entitled "Disposable absorbent article having elasticized fins" issued to Aziz et al. On March 20, 1990, describes a disposable diaper having "upright" elasticized fins (barrier folds) to improve the containment of the leg regions. U.S. Patent No. 4,695,278 entitled "Absorbent Article Having Double Folds" issued to Lawson on September 22, 1987, discloses a disposable diaper having double folds including a gusset fold and a barrier fold. U.S. Patent No. 4,704,115 entitled "Disposable Containment Garment," issued to Buell on November 3, 1987, discloses a disposable diaper or an incontinence garment having leakage channels on the side edge configured to contain the free liquids inside the garment. U.S. Patent No. 5,032,120 entitled "Disposable Absorbent Article Having Improved Leg Folds" issued to Freeland and Allen on July 16, 1991, discloses an absorbent article having leg folds having a relatively final contact force. low in relatively high elongations achieved, for example, by differential material with low contact force. The patent of the United States No. 5,087,255 entitled "Absorbent article having twisted barrier folds" issued to Sims on February 11, 1992, discloses an absorbent article having bent barrier folds with the distant shore positioned outward from the center of the nearby shore at one waist region and inward center in the other, to provide better fit around the hips / buttocks. Each of these patents is incorporated herein by reference. The diaper 20 further comprises extendable waist features that provide improved fit and containment. The extendable waist features at least extend longitudinally outward of the containment assembly 22, preferably from a respective waist edge of the absorbent core 28, and generally in shape at least a portion of the end edge of the diaper 20. Although the disposable diaper of the present invention is constructed with an extendable waist feature disposed in each waist region (an elastic waist feature 32 an extendable front waist feature 42), the discussion will focus on diapers having different configurations for each extendable waist feature. At a minimum, it is preferred that the diaper has at least one of the waist extensible features constructed in accordance with the present invention, more preferably at least the waist elastic feature 32. The waist features can be constructed as a separate element. attached to the containment assembly 22 or as an extension of other diaper elements (i.e., unitary). The waist characteristics will be described with respect to the preferred embodiments, in which certain parts or panels comprise an extension of other diaper elements such as the backsheet 26, the topsheet 24, or both, and other portions or panels comprise a separate element attached to the other portions or panels of the waist feature or other diaper panels. As used herein, the term "Cyclodextrin" includes any of the known cyclodextrins such as unsubstituted cyclodextrins containing from six to twelve glucose units, especially, alpha-, beta-, and gamma-cyclodextrins, and / or its derivatives, and / or mixtures thereof. Alpha-cyclodextrin is composed of 6, beta-cyclodextrin of 7, and gamma-cyclodextrin of 8, glucose units arranged in a donut-shaped ring. The specific coupling and conformation of the glucose units give the cyclodextrins of rigid, conical molecular structure, with a hollow interior of a specific volume. The "coating" of the internal cavity is formed by hydrogen atoms and oxygen atoms bypassing glycol-glycoxide, therefore its surface is regularly hydrophobic. These cavities can be filled with all or a part of an organic molecule of adequate size to form an "Inclusion Complex". Alpha-, beta-, and gamma-cyclodextrins can be obtained from, among others, American Maiza-Products Company (Amaizo), Hammond, Indiana. Cyclodextrin derivatives are disclosed in U.S. Patent Nos: 3,426,011, Parmerter et al., Issued February 4, 1969; 3,453,257, 3,453,258, 3,453,259, and 3,453,260, all in the name of Parmerter and others, and all also issued on July 1, 1969; 3,459,731, Gramera et al., Issued August 5, 1969; 3,553,191, Parmerter et al., Issued January 5, 1971; 3,565,887, Parmerter et al., Issued February 23, 1971; 4,535,152, Szejtli et al., Issued August 13, 1985; 4,616,008, Hirai et al., Issued October 7, 1986; 4,638,058, Brandt et al., Issued January 20, 1987; 4,746,734, Tsuchiyama et al., Issued May 24, 1988; and 4,678,598, Ogino et al., issued July 7, 1987, all of said patents being incorporated herein by reference. Examples of the cyclodextrin derivatives suitable for use herein are methyl-beta-cyclodextrin, hydroxyethyl-beta-cyclodextrin, and hydroxypropyl-beta-cyclodextrin of different degrees of substitution (D.S), accessible from Amaizo; Wacker Chemicals (USA), Inc; and Aldrich Chemical Company. Water soluble derivatives are also highly desirable. The compositions and articles of this invention optionally contain, in addition to non-complex cyclodextrins of smaller particle size, an effective amount, ie, odor controller, of several additional auxiliary odor control materials. Incorporating the auxiliary materials for odor control will increase the ability of the cyclodextrin to control odors, as well as the range of odor types that are controlled. These materials include, for example, zeolites, activated carbon, diatomite, and water-soluble antibacterial compounds, such as cetylpyridinium chloride, zinc chloride, copper salts, copper ions, chloroexidine, quaternary ammonium compounds, chelating agents, parabens, chitin, pH regulating materials and the like. Especially preferred is the zeolite material having silicate-aluminate ratios (intermediates). A wide variety of intermediate zeolites suitable for use herein are commercially available as VALFOR CP301-68, VALFOR 300-63, VALFOR CP300-35 and VALFOR CP300-56, from PQ Corporation, and the CBV100 series (different from mordenite, as noted below) from zeolites from Conteka. In the event that the zeolites of the present are optionally used in combination with activated carbon, it is preferred (for visual aesthetic purposes) to coat the carbon with the zeolite using a binder. Other odor controlling agents include diatomite, and water-soluble antibacterial compounds, such as cetylpyridinium chloride, zinc chloride, copper salts, copper ions, chloroexidine, quaternary ammonium compounds, chelating agents, parabens, chitin, regulatory materials of pH and the like. The ingredients and compositions of the encapsulated agents of the present invention are conventional ingredients and compositions known in the art. The selection of any component of the encapsulated agents, or the quantity of the encapsulated agents, is based on functional and aesthetic considerations. The components of the preferred encapsulated agents useful in the present invention are highly volatile, and the ingredients of the encapsulated agents are moderately volatile, more preferably the highly volatile ingredients with low boiling point. The ingredients of the highly volatile, low boiling encapsulated agents typically have boiling points of about 250 ° C or less. These ingredients of the highly volatile encapsulated agents are fleeting and will quickly be lost as they are released. Many of the most ingredients of the moderately volatile encapsulated agents are also lost rapidly. The ingredients of the moderately volatile encapsulated agents are those having boiling points from about 250 ° C to about 300 ° C. Many of the ingredients of the encapsulated agents as discussed below, together with their odor character, and their physical and chemical properties such as boiling point and molecular weight, are given in "Encapsulated agents and Flavor Chemicals (Aroma Chemicals)," Steffen Arctander, published by the author, 1969, incorporated herein by reference. Examples of the ingredients of the highly volatile, low boiling encapsulated agents are: anetola, benzaldehyde, benzyl acetate, benzyl alcohol, benzyl formate, sobornyl acetate, camphene, cis-citral (neral), citronellal, citronellol, acetate of citronellyl, para-cymene, decanal, dihydrolinalol, dihydromycerol, dimethyl phenyl carbinol, eucalyptol, geranial, geraniol, geranyl acetate, geranyl nitrile, cis-3-hexenyl acetate, hydroxycitronellal, d-limonene, linalool, linalool oxide, linalyl acetate, linalyl propionate, methyl anthranilate, alpha-methyl ionone, methyl nonyl acetaldehyde, methyl phenyl carbinyl acetate, laevo-menthyl acetate, menthone, isomenthone, myrcene, myrcenyl acetate, mircenol, nerol, neryl acetate, nonyl acetate, phenyl ethyl alcohol, alpha-pinene, beta-pinene, gamma-terpinene, alpha-terpinol, beta-terpinol, terpinyl acetate, and vertenex (para-tertiary-butyl-cycloexyl acetate). Some natural oils also contain large percentages of highly volatile encapsulated agent ingredients. For example, bleach contains as main components: linalool, linalyl acetate, geraniol and citronellol. Lemon oil and orange terpenes both contain approximately 95 percent d-limonene. Examples of the ingredients of the moderately volatile encapsulated agents are: amyl cinnamic aldehyde, iso-amyl salicylate, beta-caryophyllene, cedrene, cinnamic alcohol, coumarin, dimethyl benzyl carbinyl acetate, ethyl vanidine, eugenol, so-eugenol, acetate of flower, heliotropin, 3-cis-hexenyl salicylate, hexyl salicylate, lilial (para-tertiarybutyl-alpha-methylhydroxynamic aldehyde), gamma-methyl ionone, nerolidol, patchouli alcohol, phenyl exanol, beta-selinose, trichlomethyl phenyl carbinyl acetate, triethyl citrate, vanillin, and veratraldehyde. Terpenes from cedar wood are mainly composed of alpha-cedrene, beta-cedrene, and other sesquisterpenes of C15H24. The encapsulated agent / cyclodextrin inclusion complexes of this invention are formed in any manner known in the art. Typically, the complexes are formed by either bridging the encapsulated agents and the cyclodextrin together in a suitable solvent, for example, water, or, preferably, kneading / suspending the ingredients together in the presence of a suitable amount of solvent, preferably minimal , preferably water, the hard mass / suspension method is particularly desirable because it results in smaller particles such that there is no loss, or no, the size of the particle needs to be reduced. In addition, less solvent is needed and therefore less separation of the solvent is required. Disclosures of complex formation can be found in Atwood, J.L., J.E.D. Davies &; D.D. MacNichol, (Ed.): Inclusion Compounds, Vol. Lll. Academic Press (1984), especially chapter II, Atwood, J.L. and J.E.D. Davies (Ed.): Proceedings of the Second International Svmposium of Cvclodextrins Tokyo, Japan, (July 1984), and in J. Szejtli, Cvclodextrin Technology, Kluwer Academic Publishers (1988), such publications incorporated herein by reference. The microcapsules 70 for use in the present invention can be made by many of several well-known encapsulation processes. Examples of the appropriate processes include chemical encapsulation processes and mechanical encapsulation processes. A wide variety of processes exist by which the microcapsules 70 can be manufactured. These varied processes provide different techniques for producing microcapsules 70 of varying sizes, alternate materials for the composition of the capsule layer and various different functional materials within the cap. Some of these various processes are shown in U.S. Patent Nos. 3,516,846; 3,516,941; 3,996,156; 4,409,156 and 5,180,637, and the British patent disclosures Nos. 1, 156,725; 2,041, 319 and 2,048,206, and each is incorporated herein by reference. It is also desirable to have the construction of the microcapsule resist the effects of varying environmental conditions. It is therefore desirable that the breaking strength exceed 4.0 g / cm after storage at 120 ° C, and less than 1 percent relative humidity for 72 hours. This test would be done by storing it in an oven, stirring it up to a neutral environment (for example, a sealed bag or jar) until the item is at room temperature, and then measuring the resistance to rupture. It is preferred that the breaking strength be at least 8.0 g / cm and it is highly preferred that the breaking strength be at least 16 g / cm under these conditions. The article must still exhibit a breaking strength of between 2 and 90 g / cm at 20 ° C and 50 percent relative humidity. The use of the microcapsules 70 that are not sensitive to moisture in combination with these larger microcapsules 70 (ie, greater than 30 microns and up to 50 microns) provides an adhesive layer containing useful microcapsules 90. An example of a process of Mechanical encapsulation is the collision of the droplets of the material to be encapsulated (ie, in the case of this invention, an encapsulated agent or other deodorant composition) on the liquid or semisolid films of the wall material of the intended capsule; the separation of the drop thus encapsulated from the shock film; and the solidification of the wall material of the microcapsule. Chemical encapsulation processes generally include combining a first reactive material in a continuous phase capsule manufacturing vehicle and a second reactive material in the drops to be encapsulated. The drops are then dispersed in the manufacturing vehicle and a reaction is carried out between the reactive materials. The separation of the liquid-liquid phase of the polymeric material from the wall of the vehicle capsule is carried out where the phase separated polymeric material moistens and envelops the dispersed droplets to be encapsulated. A wide variety of different materials can also be used when making the capsule layer. A popular material for the formation of the layer is the reaction product by polymerization between urea and formaldehyde or melanin and formaldehyde, or the polycondensation products of monomeric or low molecular weight polymers of dimethylol urea or methiolated iodides with aldehydes. A variety of capsule-forming materials are disclosed, for example, in U.S. Patent Nos. 3,516,846 and 4,087,376 and in British Patent Disclosure Nos. 2,006,709 and 2,062,570, and each is incorporated herein by reference. The adhesive securing means 90 will preferably form a bond to the coated surfaces of the securing tabs 42 and the second holding member 41 which is stronger than the cohesion strength of the adhesive with the microcapsules dispersed therein. Although they do not wish to be bound by any particular theory, it is believed that this would allow the effective shearing force of the microcapsules 70 upon disengagement from the fastening system 40. Although it is generally desirable to have an adhesive, the absolute cohesion strength of which is less than its adhesive strength to the surface of the clamping tongues 42 and the second clamping member 41, this is not essential. When the microcapsules 70 are included within the adhesive composition 90, the effective cohesive strength of the adhesive tends to be reduced. The adhesives, which by themselves would cause the tabs 42 and the second clamping member 41 to be damaged during separation, may be used in combination with the microcapsules 70 in the practice of the present invention because of their effective cohesion strength. reduced. An adhesive securing means 90 carrying the microcapsules 70 can be coated on a portion of the adhesive surface of the fastening tabs 42 and / or at least a portion of the second fastening strip 41. This adhesive may be the only bonding material between the fastening tabs 42 and the second fastening member 41 in the sheets. Alternatively, two adhesives may be used in which one holds the microcapsules 70 in one part of the securing tab 42 and the other adhesive is used to secure the end portions of the tab 66 to the second clamping member 41. If it is present any effective amount of adhesive in the areas where the microcapsules 70 are deposited with the intention of having them removable and unbroken due to the spacing of the holding tabs 42 of the second holding member 41, then it is preferably that the cohesive strength of the adhesive is less than the breaking strength of the microcapsules 70. It has also been found that the size of the microcapsule plays a role in the usefulness of the microcapsules 70 in accordance with the practice of the present invention. Generally, the microcapsules 70 should have an average diameter of between 5 and 100 microns and preferably between 12 and 30 microns when the payload of the capsule is between 80 and 90 weight percent of the total weight of the capsule. It is highly preferred that the microcapsules 70 have an average diameter of between 14 and 42 microns and it is highly preferred that the microcapsules 70 have a diameter of between 15 and 25 microns. These dimensions play a surprisingly important role in the ability to control the rupture rate of the microcapsules 70 in the practice of the present invention. With smaller payloads (eg, from 70 to 80 percent), the microcapsules 70 should be larger to provide the necessary breaking strength. The widest scale of the average capsule size under most conditions would be about 5 to 100 microns. When 8-micron microcapsules 70 are used, a weight-effective payload of 90 to 95% is preferred. Generally preferred are microcapsules 70 having sizes between 8 and 30 microns. The microcapsules can form between 20 and 99 percent by volume of the total adhesive composition of the holding tabs 42, but most preferably between 30 and 75 percent of this volume of the total composition. The absolute release force has to be dependent on the weight of the base coating and relatively independent of the quantity of microcapsules 70 (up to 50% by weight of the microcapsules 70 per unit area). It is preferred that the microcapsules 70 have an average diameter of between 5 and 100 microns, the cohesion strength of the layer of the adhesive composition being less than the bond strength between the adhesive composition and the coated surface of the fastening tab 42 and the second clamping member 41, the tensile strength of the microcapsules being less than the cohesion strength of the adhesive composition, and the breaking strength of the layer of the microcapsule-containing adhesive composition at 50% relative humidity being between 0.5 ounces by 5 and a half linear inches (greater than 1.0 g / cm and less than 20 g / cm). It is preferred that the breaking strength of the microcapsules 70 exerted by the clamping tabs 42 and the second clamping member 41 exceed 2.0 g / cm and be less than 16 g / cm and most preferably exceed 2.5 g / cm and is less than 10 g / cm. In highly preferred embodiments, the nature and composition of the adhesive is not critical to the practice of the invention as long as the adhesive is capable of adhering the microcapsules 70 adherently to the substrate. The amount of adhesive should be sufficient to keep the microcapsules 70 in place on the surface of the substrate until the microcapsules 70 rupture upon removal of the user's diaper 20. Any kind of adhesives, including but not limited to polyurethanes, polyacrylates, polyvinyl resins (eg, polyvinyl alcohol, polyvinyl chloride), polyamides, polyesters, polyolefins, starches, gum arabic, gelatin and the like, can be easily used in the practice of the present invention. Preferably, the adhesive used as the securing means 90 is an acrylate or methacrylate-based adhesive system comprising elastomeric copolymer, infusible, solvent-dispersible, solvent-insoluble, inherently sticky microspheres, as disclosed in U.S. Pat. Do not. 3,691, 140. Alternatively, this adhesive composition may comprise hollow pressure, elastomeric, acrylate polymer, infused, solvent-dispersible, solvent-insoluble, inherently tacky, microspheres, as disclosed in U.S. Pat. 5,045,569. Washing the microcapsules 70 before mixing them with the adhesive often tends to provide greater consistency in their properties by removing unreacted, low molecular weight materials. In another aspect, the present invention involves a novel article that occluding a thermoplastic substrate, preferably flexible, which is partially embedded therein within the rupturable microcapsules 70. In this embodiment, a binder resin is required. This article can be used in situations where good retention and protection of the microcapsules is required, but where access to the microcapsules 70 must be retained. The methods for applying the binder (with the microcapsules) to the substrate can vary, depending on the methods available and economic more than any other parameter. Suitable methods of application include air cutting, gravure coating and printing methods, including silk screening, gravure and flexographic techniques. The binder (with the microcapsules) can be applied in either a continuous or discontinuous pattern in the substrate. Capsule wall materials suitable for use in accordance with the teachings of this invention include any suitable polymeric film-forming material. For example, the microcapsules 70 can be made from natural hydrophilic polymeric materials such as gelatin, gum arabic, starch, carrageenan and zein; natural polymeric materials modified in some way such as ethyl cellulose, carboxymethyl cellulose, shellac, resin and nitrocellulose; and other polymeric materials such as polyvinyl alcohol, polyethylene, polystyrene, polyacrylamide, polyether, polyester, polybutadiene, silicone, epoxy and polyurethane. The particular encapsulated agents or encapsulated deodorants do not form part of the invention and can be varied to such a high degree to contravene classification or description. Reference is made, on the other hand, "Cosmetics, Science and Technology", second edition, edited by M. S. Balsam and Edward Sagarin and published by p John Wiley & Sons, Inc., of New York 1972. In particular, reference is made to Chapter 32, "Fragrance" written by M. S. Balsam for examples of the variety of possible encapsulated agent formulations. The material contained within the microcapsules 70 can be any of a variety of liquids, including solutions, dispersions and materials in gel form.

Preferred types of ingredients are organic solids which are fragrance releasing materials that easily volatilize upon breaking microcapsules 70. The type of highly preferred ingredients would be fragrant materials (such as essences and most preferably medium to highly volatile perfumes) or materials that provide vapors. or chemically active liquids (for example, bacteriostatic or deodorants). Whatever the fragrance, these or these must be chosen to be compatible with the fastening system 40 and all other components of the diaper. Although particular embodiments of the present invention have been described and illustrated, it would be obvious to those skilled in the art that other changes and modifications can be made without departing from the spirit and scope of the invention. Therefore, attempts are made to protect all these changes and modifications within the scope of the invention in the appended claims.
