as used herein , the term “ disposable 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 the various exudates discharged from the body , and to articles which are intended to be discarded after a single use ( i . e ., they are not intended to be laundered or otherwise restored or reused ). a preferred embodiment of the disposable absorbent article of the present invention , as indicated by numeral 8 , is shown in fig1 . as used herein , the term “ absorbent article ” refers to a garment generally worn by infants and incontinent persons , which is worn about the lower torso of the wearer . it should be understood , however , that the present invention is also applicable for use in other disposable absorbent articles such as incontinent briefs and the like . fig1 is a plan view of an absorbent article 8 . the absorbent article 8 comprises a liquid pervious topsheet or coverstock 10 ; a liquid impervious backsheet 12 , an absorbent core assembly 14 disposed , for example , between the coverstock 10 and the backsheet 12 ; a pair of fasteners 16 ; flexible elastic leg wraps 18 ; internal topsheet 19 ; and elastic members 20 secured within the leg wraps 18 and capable of defining a plurality of fluid dams 90 when worn ( as shown in fig2 ). the liquid pervious coverstock 10 , absorbent core 14 , topsheet 19 and liquid impervious backsheet 12 may be assembled in a variety of well known configurations as appreciated by those of ordinary skill in the art . fig2 and 3 are plan views of the absorbent article 8 of the present invention in the flat - out , uncontracted state ( i . e ., with all elastic induced contraction removed and prior to any folding operation performed on the article or addition of secondary topsheet 19 ). the novel secondary topsheet 19 is not shown in fig2 - 24 . fig3 is a plan view of the other side ( outer side ) of absorbent article 8 of fig2 . referring to fig2 and 3 , the absorbent article 8 comprises a liquid pervious topsheet or coverstock 10 ; a liquid impervious backsheet 12 , an absorbent core assembly 14 disposed , for example , between the coverstock 10 and the backsheet 12 ; a pair of fasteners 16 ; flexible elastic leg wraps 18 ; elastic members 20 secured within the leg wraps 18 and capable of defining a plurality of fluid dams 90 when worn ( as shown in fig2 ). the liquid pervious coverstock 10 , absorbent core 14 and liquid impervious backsheet 12 may be assembled in a variety of well known configurations as appreciated by those of ordinary skill in the art . fig2 and 3 illustrate an embodiment of the absorbent article 8 in which the coverstock 10 and the backsheet 12 are coextensive and have length and width dimension generally larger than those of the absorbent core assembly 14 . the coverstock 10 is superposed on the backsheet 12 thereby forming a periphery of the absorbent article 8 comprising end edges 28 and 30 , and longitudinal edges 32 and 34 . the absorbent article 8 has waist regions 36 and 38 extending , respectively , from the end edges 28 and 30 , of the absorbent article periphery toward the lateral centerline 40 of the absorbent article 8 a distance of from about ¼ to about ⅓ the length of absorbent article 8 . the waist regions 36 and 38 comprise those portions of the absorbent article 8 which , when worn , is positioned between the legs of the wearer and covers the lower torso of the wearer . referring to fig4 , the absorbent core assembly 14 includes an absorbent core 42 , a liquid permeable nonwoven coverstock 10 and a liquid impermeable backsheet 12 . additional layers of a material , such as additional absorbents , cellulose materials or nonwoven 44 , that provide additional functionality such as storage of urine , fast acquisition of urine and / or distribution of urine , may also be provided within the core assembly . the absorbent core 42 may be composed of combinations of cellulose based absorbent materials , super - absorbent polymers , synthetic nonwoven materials or other absorbent materials . the disposable , absorbent article 8 is joined together in such a way that the coverstock 10 and backsheet materials 12 entirely enclose the absorbent core 42 . the coverstock 10 and backsheet 12 may be directly joined together or indirectly joined together through an intermediate portion . materials suitable for each of the core 42 , coverstock 10 and backsheet 12 are generally known in the art . the nonwoven coverstock 10 provides a fluid permeable upper layer of the absorbent core assembly to contain the absorbent core components and allows the passage of body exudates into the absorbent core 42 during use . preferably coverstock 10 has length and width dimensions greater than that of the absorbent core assembly 42 . these extended side edges of a nonwoven coverstock 10 may extend to the lateral edges 32 , 34 of the absorbent article and serve to provide the upper layer of the composite containing the elastic members 20 . the lateral sides of a nonwoven coverstock 10 , which extend over the elastic leg wraps 18 , may or may not be permeable to aqueous fluids . the coverstock 10 is preferably compliant , soft feeling , and non - irritating to the wearer &# 39 ; s skin . further , the coverstock 10 is liquid pervious permitting liquids to readily penetrate through its thickness . a suitable coverstock may be manufactured from a wide range of materials , such as porous foams , reticulated foams , 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 . preferably , it is made of a hydrophobic material to isolate the wearer &# 39 ; s skin from fluids in the absorbent core 42 . a further embodiment of an absorbent article involves the use of a coverstock with zones of differing hydrophilic nature achieved by selective treatment of the material with agents which impart a hydrophilic nature to the nonwoven , e . g . surfactants . in this embodiment the coverstock will have a hydrophilic zone in the centre of the sheet , this central zone aligned to correspond with the region of the article where the absorbent core is disposed . the side zones , laterally adjacent to this central zone , may be less hydrophilic or more hydrophobic than the central zone . this produces an article having a hydrophilic , water permeable coverstock above the absorbent core to allow passage of urine into the core , and hydrophobic , water impermeable regions of said coverstock above the leg gathers to provide a dry feeling around the legs and to resist leakage of fluid through the leg wraps 18 . leg wraps 18 may include multiple elastic strands 20 associated with each side leg panel 18 . in one embodiment , elastic strands 20 are sandwiched between the nonwoven coverstock 10 and the backsheet laminate 12 . the composite of the elastic strands 20 , nonwoven coverstock 10 and backsheet laminate 12 is secured by using any suitable means familiar to those skilled in the art , such as adhesive bonding using slot coat or spray , spiral or swirl application of hot melt adhesive or ultrasonic bonding . in one embodiment six elastic strands 20 are shown per side leg panel 18 . the elastic strands 20 could be yarns of natural or synthetic rubber latex , or synthetic elastic materials such as spandex . the choice of elastic materials is not limited to elastic strands , but may also include ribbons of elastic materials , elastomeric films , elastic scrims , elastic and nonwoven composites and the like . fig4 is a cross - sectional view of the embodiment of fig2 and fig3 wherein the backsheet material 12 is represented as a laminate of an air porous or air non - porous , fluid impermeable , polyethylene or polypropylene film 52 and a fluid impermeable polypropylene nonwoven 54 . such materials are known to those skilled in the art as clothlike or textile backsheet . it is also suggested that the backsheet material 12 can be a single layer of polyethylene film or other suitable composite material . the fasteners 16 may involve pressure sensitive adhesive fastening tapes which secure to a frontal portion of silicone , “ release ” coated polyolefin film , hook and loop tapes or any other suitable fastening medium . the absorbent article may also have an elasticized waistband using an elastic foam , elastic film , elastic strands or other suitable elastic , elastic laminate , stretchable material affixed to or between the coverstock and backsheet portions . an example of the disposable absorbent article according to the present invention provides a close fitting seal around the thighs of the user , thereby significantly improving its leakage prevention capability . the close fitting seal of the inventive garment is further enhanced through addition of fastening element 16 . the fastening element 16 may be provided by known adhesive elements or hook fastening devices . the hook fastening element may be selected so as to be engageable with the loops formed on the surface of a nonwoven fabric . thus , the nonwoven material of the stretchband panel provides the loop element of a hook and loop fastening system similar to those generally known in the art . in further embodiments , a loop landing tape may be located near the front waist region of the outside face of the inventive article , and a pair of hook fastening elements may be located in the rear non - elasticized zones of each stretch panel . the fastening portion is therefore attached directly to the central body rather than to the front edge of the stretch panel . the loop landing tape may be constructed from a knitted , extruded , or non - woven material , as is generally known in the art . fig5 and 6 show various other embodiments of absorbent articles 8 . fig5 shows an alternative embodiment where the lateral side edges 32 , 34 of the absorbent article 8 are inwardly curved to define cut - out regions 56 . this shaped product facilitates a better fit of the product around the waist of the wearer without increasing the amount of material within the side panel that would be gathered around the user &# 39 ; s legs when worn . fig5 discloses elastic elements 20 which are oriented parallel to at least a portion of the lateral side edges 32 , 34 of the absorbent article 8 . in comparison , fig6 depicts elastic elements 20 which follow the inwardly curved side portions of the absorbent article . descriptions of some additional configurations suitable for use with the present invention are found in u . s . ser . no . 11 / 295 , 781 , entitled “ disposable absorbent article having leg wraps and method of making same ”, hereby incorporated by reference and made a part of the present disclosure . additional concepts of the present are disclosed in fig6 wherein the absorbent article 8 is defined by a central absorbent core assembly 14 and a pair of leg wraps 18 separated from the absorbent core assembly 14 by inelastic regions or zones 58 of substantially decreased elasticity 58 . each inelastic zone 58 is defined between the absorbent core assembly 14 and the nearest elastic strand member 20 of the leg wraps 18 . referring to fig7 , a distance , h , is defined between the lateral edges of the absorbent core assembly 14 and the elastic strand 20 nearest to the core assembly 14 or stated another way , the strand 20 furthest from the lateral edges 32 , 34 of the absorbent article 8 . the spacing between the strands 20 of elastic material is represented as distance , e . fig8 also illustrates another embodiment of the fasteners 16 which may be utilized in the practice of the invention . fasteners 16 may be provided on the outward portion of side panels 35 having one or more regions of elasticity 37 and one or more regions of inelasticity 39 . other fasteners and side panel constructions are disclosed in u . s . ser . no . 11 / 113 , 114 , entitled “ extensible side panels for use with convertible absorbent articles ”, hereby incorporated by reference and made a part of the present disclosure . in preferred embodiments of the present invention , the strand 20 count for each elastic leg wrap 18 ranges from 4 to 10 strands , and more preferably between 4 to 6 strands . the distance , h , ( width of inelastic zone 58 ) is preferably between 19 mm to 64 mm , and more preferably between 25 mm to 40 mm . the distance , e , between the strands 20 is preferably between 4 mm to 40 mm , more preferably greater than 6 mm , and yet more preferably approximately 8 mm . leg cuff elements 64 may be provided upon a top surface of the coverstock 10 of an absorbent article 8 . leg cuff elements 64 may be defined by material of the coverstock layer 10 , or may be of different material attached in know manners to the top surface . the construction of leg cuff elements 64 within the absorbent article 8 would be understood by those of ordinary skill in the art . as depicted in fig9 - 13 , leg cuff elements 64 may be provided at different distances away from absorbent core 14 . fig9 - 24 show cross sections of alternate embodiments of the topsheet , backsheet and absorbent article suitable for use with the internal topsheet 19 ( not shown ). in some embodiments , the continuous full width nonwoven coverstock 10 may be replaced with a three - piece construction . in the central region 10 of the absorbent article a material 66 permeable to aqueous fluids such as a hydrophilic treated polypropylene nonwoven is placed over the absorbent core to contain the absorbent materials and to allow the passage of urine into the absorbent core 14 . another material element 68 forms the top layer of the elastic side panels 18 along each lateral side edge of the article . this material may be selected from suitable materials such as water permeable polypropylene nonwovens , water impermeable polypropylene nonwovens , polyethylene film and the like . fig9 shows the absorbent core covering material 66 overlapping the outer elastic composite covering material 68 . fig1 shows the absorbent core covering material 66 under - lapping the material 68 covering the elastic composite . in the embodiment of fig1 , an absorbent core assembly 42 is enclosed by a nonwoven , fluid permeable coverstock 70 and a fluid impermeable backsheet 72 . in this embodiment the coverstock 70 and backsheet 72 do not extend to the outer edges of the absorbent article . a single ply of nonwoven web 74 is folded around and encloses the elastic strands 20 . this elastic composite is then attached to the sides of the absorbent core assembly 14 using any suitable means , for example using hotmelt adhesives or ultrasonic bonding . in the example of fig1 , the coverstock material 10 extends continuously over the full width of the absorbent article 8 , as is the case in the first embodiment of the invention . in this embodiment a separate piece of suitable material 78 is used to enclose the underside of elastic composite on each leg wrap 18 . fig1 shows an alternate embodiment to that shown in fig1 . this embodiment differs in that two separate layers of suitable material are used to enclose the elastic strand elements 20 within elastic composite elements which are affixed between the coverstock and backsheet portions of the core assembly 14 . fig1 - 24 show still further embodiments where the underside of the elastic composite side panels are formed from a material such as the fluid impermeable polypropylene nonwoven which extends continuously across the full width of the absorbent article . fig2 - 28 depict a disposable absorbent article as fitted to the wearer . the novel internal topsheet 19 is shown in these figures . the absorbent article 8 folds inwards at point 80 and outwards at point 82 . the absorbent article 8 may naturally conform to the shape depicted in fig2 - 28 . it may be necessary or useful to prefix the article in this configuration by applying spots of adhesive or by using any other suitable means to ensure that the article is fitted correctly to the wearer . the outcome of this folding pattern of the article is two fold . first , the elastic leg wraps 18 are desirably positioned against the wearer &# 39 ; s body and fit securely around the upper thighs and buttocks of the user . this serves to create a generally fluid impermeable seal around the legs , crotch and thighs of the user , which reduces the incidence of leakage . second , the absorbent core assembly 14 is held away from the body of the wearer , particularly in the crotch area of the article . this serves to create a void space 84 between the user &# 39 ; s body and the absorbent core assembly 14 . this void space 84 may have an approximately trapezoid appearance as demonstrated in fig2 , with a base having a length approximately equal to the width of the absorbent core 42 , sides of a length approximately equal to dimension x , and a top length dependent upon the angle formed between the base and sides . portions of the article 8 can pivot or rotate relative to each other so that the absorbent core 42 and leg wraps 18 can freely move upon the wearer . this pivoting effect enables the leg wraps 18 to move during use while maintaining an effective leg seal . void space 84 created by the structure of the absorbent article 8 serves to hold the absorbent core 42 away from direct contact with the skin or body of the wearer . for example , rewet or the wetting of the user &# 39 ; s skin by body waste fluids not completely captured by the superabsorbent materials within the absorbent core 42 is reduced , resulting in improved comfort for the wearer . referring particularly to fig2 and 28 , reservoir 26 is a structure in which body exudates can be collected , contained and held . exudates float or flow along the top surface flow into and down the side walls of the reservoir 26 to be collected in the bottom of the reservoir 26 until the absorbent article 8 can be removed . the reservoir 26 is , therefore , especially effective for exudates , particularly loose fecal materials , that are not easily absorbed by the absorbent core 14 and tend to “ float ” on the coverstock 10 . the reservoir 26 may be disposed at least in part between the elastic members 20 and the longitudinal centerline of the absorbent article 8 , e . g ., by material within the zone of decreased elasticity 58 . the reservoir 26 may be constructed of materials known in the art which are compliant and conformable enough to present a pocket or well - like shape . the material may be absorbent , wicking or impermeable to exudates . for example , the reservoir 26 may comprise an element ( i . e ., the coverstock 10 , the backsheet 12 or the leg wrap 18 ) or any combination of these elements or other elements of the absorbent article 8 configured or folded to present a reservoir . in addition , the reservoir 26 may have a variety of shapes and cross - sections provided that a pocket or well - like shape is formed to contain and hold the exudates . for example , the reservoir 26 may have a semi - circular , square or parabolic cross - section . preferably , the reservoir 26 is formed by folding material within the zone of decreased elasticity 58 and securing the folded portion to portions of the coverstock 10 adjacent the absorbent core 14 . fig2 illustrates the temporary reservoir 26 and void 84 wherein the reservoir 26 contains fluid prior to absorption by core 14 . fluid is prevented from passing through side leg panels 18 by the series of elastic gathers defining a plurality of fluid dams as indicated by numeral 90 . fluid which passes through one of the fluid dams 90 encounters the furtherly - outward fluid dam 90 . as a result , multiple sealing structures are provided by the leg wraps 18 . it has been found that the desired trapezoid shape of void 84 and / or reservoir 26 can be difficult to form and maintain in every application as it can be dependent on how the absorbent article 8 is placed on the user and movements the user might make whilst wearing the diaper . in order to improve the likelihood that this shape exists in the product when the diaper is fitted to the wearer and to improve the stability of the desired shape during use it is possible to pre - fold the diaper in the side regions of the product , and fix the fold with the addition of a bonding element . this bonding element could be any combination of adhesive , thermo - bonding , ultrasonic bonding or any other suitable method of bonding plastic and nonwoven based materials . it is also envisaged that this fold - fixing bond point could also be obtained using a hook and loop engagement system or other non - permanent fixation means . in some embodiments of the present invention a z - shaped fold is formed in the leg wrap 18 of the diaper during manufacture . the leg wraps 18 can be folded in towards the core and a suitable bonding method is then used to fix this fold in position . secondly , the side panel is then folded back away from the core . an optional bonding method can be used to fix this fold in position . fig2 shows a cross - section of the folded diaper with the fold - fixing bonded areas indicated as numeral 94 . bonded areas 94 are optional and embodiments of the present invention may not necessarily include bonded areas 94 . similarly , other embodiments of the present invention may include one or more bonded areas 94 . bonding of the folded side region can be achieved by a longitudinally continuous application of adhesive using any suitable application method , such as spiral spray , intermittent bead or continuous bead . alternatively a continuous line of an ultrasonic or thermal bonding method could be used . fig3 shows a diagram of this embodiment . in further embodiments of this invention the longitudinal fold - fixing bonding points can be discontinuous . this has the advantage of allowing selection of zones on the diaper where the fold can open up to provide maximum void space , whilst effectively pinning the fold in position in other selected areas . in the embodiment of fig3 , two fold fixing bond points per side panel 18 are provided in a region close to the front and rear edges of the diaper . in another embodiment of fig3 these bond points are moved towards the center of the diaper . in yet another embodiment of fig3 , a single bond point per side panel is provided in the center crotch region of the diaper . the diagrams above show possible variations of the folded chassis of this invention and the possible positions for fold - fixing bond points . however further embodiments of this invention not shown by the drawings above are also possible . the position of the fold is variable and could be moved laterally to any position within the side panel or , alternatively , sections of the absorbent core could be incorporated into the folded region . the number of fold - fixing bond points per side panel is also variable . in addition to or in place of the use of the aforementioned fold - fixing bond points , providing a topsheet gap that is narrower than the back sheet gap can assure the maintenance of void 84 and / or reservoir 26 . in a preferred embodiment illustrated in fig3 , secondary topsheet 19 ensures that the preferred void and / or reservoir is created and maintained even with variations in donning or fitting of the absorbent garment . the secondary topsheet 19 may also be additionally bonded to the absorbent as illustrated in fig3 . in another embodiment shown in fig3 , the primary topsheet 10 can be folded and bonded to itself to create the void and / or reservoir . fig3 shows a partial length secondary topsheet 19 placed about the center of the diaper . further embodiments not shown by the drawings are also possible . the positioning of the partial length topsheet 19 can be optimized for best performance in relation to the containment of fecal exudates and its separation from the skin . a plurality of topsheets 19 can also be envisioned and optimally positioned for best performance in fecal exudates handling . additionally , topsheet 19 can have slits or holes to assist in the capture of liquid and solid exudates . it is important that the tension forces provided by the elasticized side leg panel 18 are neither too low nor too high . if the tension forces provided by the side leg panel 18 are too low , the absorbent article 8 may not fit very closely in certain regions around the legs and the waist and the absorbent article ability to prevent leakage will be compromised . high tension forces may constrict the user &# 39 ; s thighs and cause discomfort . in a typical prior art disposable absorbent article , the positioning of elastomeric elements and the type of elastomeric element placed does not vary along the length of the stretch panel . the elasticity or elastication of the stretch panel is , therefore , uniform along the stretch panel length . when elongated in a uniform manner , the overall tension provided by the stretch panel is also uniform along its length . the magnitude of this uniform tension depends on the overall elongation of the leg wraps 18 . when the absorbent article 8 is worn , however , the elongation of the leg wrap 18 along it length is generally non - uniform , and thus , the tension generated varies . as a result , there may be regions about the length of the leg wrap 18 that are undesirably too loose or too tight . in one respect , regions or zones devoid of elastic elements — e . g ., zones provided for finger lift area and landing area — are also distinct regions of elasticity formed by pre - determined placement of elastic elements . these regions of elasticity differ , however , in the sense that the elastic elements do not impart elasticity to the stretch panel in these regions in contrast to the distinct regions of imparted elasticity in the vicinity of the elastic elements . descriptions of some configurations suitable for use with the present invention are found in u . s . ser . no . 10 / 441 , 469 , entitled “ disposable absorbent article with elasticized side panels and method of making same ”, hereby incorporated by reference and made a part of the present disclosure . in addition , embodiments of the absorbent article 8 achieve increased comfort by positioning the elasticized side flaps closer to the side edge of the absorbent core 42 . thus , when initially placed on the wearer , the elasticized side flaps ride in the groin areas along the inner thighs of the wearer thereby providing a better initial fit . this positioning provides a better initial fit on the wearer because elasticized side flaps of conventional diapers are often initially positioned farther down on the thigh of the wearer and subsequently tend to ride or creep up into the groin regions of the wearer during use . because the side flaps are drawn up , gaps tend to form in the legs and waist providing less comfort for the wearer . however , because the present invention initially positions the elasticized leg wraps 18 in the groin areas , sagging of the diaper is reduced resulting in increased comfort for the wearer . the foregoing description of the present invention has been presented for purposes of illustration and description . it is to be noted that the description is not intended to limit the invention to the various apparatus and processes disclosed herein . various aspects of the invention as described above , may be applicable to other types of disposable absorbent articles and garments , and processes for making the same . for example , the feature of an elasticized side panel having the fastening portion described above , may be incorporated in other disposable absorbent articles such as training pants , etc . moreover , the feature of an elasticized side panel as having the characteristic elasticity described above may also be incorporated in other disposable absorbent articles and garments . such variations of the invention will become apparent to one skilled in the relevant consumer products , or other relevant art provided with the present disclosure . consequently , variations and modifications commensurate with the above teachings , and the skill and knowledge of the relevant art , are within the scope of the present invention . the embodiments described and illustrated herein are further intended to explain the best modes for practicing the invention , and to enable others skilled in the art to utilize the invention and other embodiments and with various modifications required by the particular applications or uses of the present invention .
