Top sheet 24 is adjoined 66 placements of absorbent cores 28 inner surfacies, and suits to be connected with back lamella 26 with this surface with all means (not shown) that connects as known in the art.The connection means that are fit to are being described with the declaratives that absorbent cores 28 is connected about back lamella 26.In a preferred embodiment of the invention, top sheet 24 and back lamella 26 are directly linked to each other mutually along the periphery of diaper, and are connected the mode that the means (not shown) is directly connected in absorbent cores 28 by certain, and are connected together indirectly.

Top sheet 24 is submissive, soft feel, and non-stimulated to the skin of wearer.And top sheet 24 is suitably and can sees through liquid, so that liquid (as urine) passes its thickness rapidly.The top sheet 24 that is fit to can be used many material manufacture, as porous foam; The network structure foam; The plastic sheeting that hole is arranged; Perhaps natural fiber (wood or cotton fiber), synthetic fibers (as polyester and polypropylene fibre) or natural and blended fabric of synthetic fibers or non-woven network.Top sheet 24 is suitable to the hydrophobic material manufacturing, so that the skin of wearer completely cuts off (promptly preventing to rehumidify) with the liquid that sees through top sheet 24 and be housed in the absorbent cores 28.If top sheet 24 is by the hydrophobic material manufacturing, then the upper surface of top sheet 24 will be done the hydrophilic processing at least, so that liquid more promptly passes through top sheet.This has reduced body exudates and has flow to outside the top sheet 24, is not absorbed the possibility that core 28 absorbs and there is to see through top sheet 24 downwards.Top sheet 24 can be endowed hydrophilic by handling with surfactant.The method that is fit to of handling top sheet 24 with surfactant comprises, with surfactant spraying top sheet 24 and this material of submergence in surfactant.Relevant this processing and hydrophilic are discussed in more detail, be included in the United States Patent (USP) 4 for " absorbent article that multi-layer absorber layer is arranged " such as the people's exercise question of authorizing Reising on January 29th, 1991,988,344, authorize the United States Patent (USP) 4 of people's exercise question such as Reising for " absorbent article that rapid collection absorbent cores is arranged " with on January 29th, 1991, in 988,345, its every part patent all is the list of references of this paper.

There are many kinds of manufacturing process can be used to make top sheet 24.Such as, top sheet 24 can be the non-woven network of fiber.When top sheet 24 comprised non-woven network, net can be to curl up agglutinatingly, be carded to, the wet method spreading, melt and spray, add that water twines, and the combination of above-mentioned or similar approach or the like.A kind of suitable top sheet 24 usefulness fibers are made hot sticky the forming of field known method combing.A kind of satisfactory top sheet 24 comprises the weaving length polypropylene fibre with about 2.2 numbers, and in this article, term " textile fabric length " is meant those length fiber about 15.9mm (0.625inches) at least.Top sheet 24 is suitable have about 18 to 25 grams/square metre pivot weight.A kind of suitable top sheet, be trade mark be P-8 by Veratec, Inc.a divsionof International Paper Company, of Walpole, Mass. company makes.

Diaper 20 is also suitable to comprise elastic shank cuff 32, so that the bigger liquid and the capacity of other body exudates to be provided.Each elasticized leg cuffs 32 can comprise several different concrete forms, to reduce the leakage of leg area body exudates.(the shank cuff can and be also referred to as the lower limb hoop sometimes, limit, side door leaf, intercept cuff, or elasticity cuff) United States Patent (USP) 3,860,003 discloses a kind of disposable diaper, and it has the collapsible shank opening of a band limit, side door leaf and one or more elastic parts, so that an elastic shank cuff (constraint cuff) to be provided.Authorize the United States Patent (USP) 4,909,803 of people's exercise question such as Aziz March 20 nineteen ninety, disclose a kind of disposable diaper with the limit, " holding up " elasticity door leaf (obstruct cuff) of improving accommodating property of leg area for " disposable absorbent article on limit, flexible door leaf ".JIUYUE was authorized the United States Patent (USP) 4,695,278 of Lawson exercise question for " absorbent article that two cuffs are arranged " on the 22nd in 1987, disclosed a kind of two cuff disposable diapers that comprise the constraint cuff and intercept cuff that have.Although each elasticized leg cuffs 32 can be configured to be similar to above-mentioned lower limb hoop, limit, side door leaf intercepts cuff, or any one form of elasticity cuff, the above-mentioned United States Patent (USP) of quoting 3,860, the 003 described constraint cuff but each elasticized leg cuffs 32 suits to comprise.

And diaper 20 suits to comprise an elastic waist 34 that is used to help improve dress and accommodating property.But the part that this elastic waist 34 is diaper elastic dilatation and contraction and a zone are in order to dynamically to be worn in the waist of wearer.Elastic waist 34 suits from least one waist end 70 outside longitudinal extension of absorbent cores 28, and is formed up to the part of oliguria cloth 20 terminations 58 usually.Although diaper can be configured to the form of a single elastic waist, disposable diaper generally has been configured for two elastic waists, and one is positioned at 50, one of first waist areas and is positioned at second waist area 52.And, although elastic waist 34 or its any member can be the independent components that is fixed on the diaper 20, elastic waist 34 also can be configured to the extension of other elements of diaper, as back lamella 26 or top sheet 24, preferably be back lamella 26 and top sheet 24 together.Waist 34 can be configured to many different profiles, comprise be disclosed in the United States Patent (USP) 4,515,595 of authorizing people such as Kievit on May 7th, 1985 and the United States Patent (USP) of authorizing Buell 5,151,092 that pro-is quoted in those; Every part of list of references all is cited in this article as a reference.

In a preferred embodiment of the invention, diaper 20 also comprises auricular lappet sheet 62, and it accommodates each vertical termination 56 of assembly 22 from second lumbar region 52 laterally protruding.Auricular lappet sheet 62 has one can connect into around the structure of the shank and the waist of wearer with first waist area 50.Auricular lappet sheet 62 can be taked many different sizes, shape, profile, and material.Auricular lappet sheet 62 can be a part of making one or more diaper element material, comprises top sheet 24 and back lamella 26.In addition, auricular lappet sheet 62 can be an independent component or a plurality of element that is connected on the diaper.The material that is suitable for doing auricular lappet sheet 62 comprises the fabric net; Non-woven network; The thin film that comprises thin polymer film; Foam; Comprise that pellicular cascade, non-woven laminate or zero strain are stacked in interior laminated material; Elastomer; Composite; The perhaps combination in any of this paper above-mentioned material or the material as scalable side direction embedding limit known in this field.Auricular lappet sheet 62 can be connected to by any method known in the art and accommodate on the assembly 22; Such as, can with heating or the binding agent that do not heat, heat bonding, pressurized adhesion, ultrasonic bonds, bonding or other methods well known in the art of dynamic power machine join auricular lappet sheet 62 continuously or intermittentlies to and accommodate on the assembly.

Diaper 20 also comprises with assembly 22 each the vertical termination 56 of accommodating of diaper 20 and adjoins the scalable flank 30 of layout, is preferably on first lumbar region 50.(in this article, term " layout " is meant, other elements of the element of absorbent article and absorbent article are done as a whole, or as the independent component that is connected on other elements of absorbent article, and be formed (connect or location) situation in a specific place or position) but scalable flank 30 provides the part of an elastic telescopic, because scalable flank 30 can stretch and shrink the limit of diaper 20, so successfully dress at first aspect the diaper at wearer, aspect the time of in whole wearing process, spending well after diaper has been loaded with effluent, all more comfortable and appropriate.Even because diaper is worn the wearer and dressed diaper asymmetricly, diaper also can " self-adjusting " arrive good wearing form in its wearing process, so scalable flank 30 also makes diaper obtain more high efficiency use.Scalable flank 30 of the present invention also makes the buttocks of wearer have the same good dynamic wearing characteristic with waist, has reduced near the possibility of sagging and the gap waist that can cause leakage and the shank, has improved comprehensive comfort of freedom of motion and wearer simultaneously.

The scalable flank 30 that is positioned at first lumbar region 50 although diaper 20 of the present invention suits to have; On the other hand, diaper 20 also can have and is positioned at second lumbar region 52, perhaps the scalable flank 30 that all has in first lumbar region 50 and second lumbar region 52.Although scalable flank 30 can be configured to many profiles, there is the example of scalable flank diaper to be disclosed in the United States Patent (USP) 4,857,067 for " disposable diaper that the degree of tightness ear is arranged " such as the people's exercise question of authorizing Wood on August 15th, 1989; Authorize people's such as Sciaraffa United States Patent (USP) 4,381,781 May 3 nineteen eighty-three; Authorize people's such as VanGompel United States Patent (USP) 4,938,753 July 3 nineteen ninety; With exercise question that on November 19th, 1993, people such as Miguel A.Robles submitted to in the U.S. Patent application 08/155,048 of " absorbent article that multidirectional scalable flank is arranged ", they all are cited in this article as a reference.

Diaper 20 also suits to have one and is used for diaper is lain in wearer fastening system 48 on one's body.The mode of fastening system 48 bracings is being maintained first lumbar region 50 and second lumbar region 52, to form the lateral edges of a closure.Fastening system 48 also keeps extended state in scalable flank 30, so that diaper 20 is through on the body of wearer, better dynamically wear characteristic for the shank and the providing of waist of wearer on every side simultaneously.Fastening system 48 can comprise any connected mode known in the art, comprises (but unrestricted) contact adhesive, the material of adhesion, and mechanical fastening device is as hook and ring set type securing member, and the combination of these modes and any other modes known in the art.The example of the adhesive tape lug fastening system that is fit to is disclosed in the United States Patent (USP) 3,848,594 of authorizing Buell on November 19th, 1974; Authorize in the United States Patent (USP) 4662875 of hirotsu and Robertson with on May 5th, 1987; Every part of patent all in this article as a reference.Be used to the present invention includes other closed-system examples of mechanical closure system, be disclosed in the United States Patent (USP) 4,869,724 that JIUYUE in 1989 was authorized Scripps on the 26th; Authorized the United States Patent (USP) 4,848,815 of Scripps on July 11st, 1989; Authorized Weil on 7th with JIUYUE in 1993, Buell is in the United States Patent (USP) 5,242,436 of Clear and Falcone; Its every part patent all in this article as a reference.

Diaper 20 is suitable to one of lumbar region, location, preferably first lumbar region 50 is below the back of wearer, and between wearer two lower limbs stretching diaper 20 remainders and be applied to wearer, so that other lumbar region, preferably second lumbar region 52 strides across wearer and locatees in the predecessor.Allow the scalable flank of of diaper 30 round wearer then, fasten one of first fastening assembly 40 that places on each scalable flank 30 simultaneously.The diaper wearer repeats this step to another scalable flank 30 then.By fastening first fastening assembly 40 and second fastening assembly 42 that is positioned on second lumbar region 52, form the closure circle of waist.By forming the closed circle of waist, new diaper 20 has been through on one's body the wearer appropriately.If diaper 20 is worn asymmetricly, diaper 20 will self-adjusting arrive proper state during wearing.In case wear on one's body the wearer, scalable flank 30 will stretch along with the motion of wearer and shrink, and with in the process of wearing, provides the good dynamic characteristic of wearing, and spends diaper 20 well and has carried the time behind the effluent.This is good dynamically wears the sagging that characteristic reduced waist and buttocks part diaper 20 and tears, and increases the comfort of wearer simultaneously.

As mentioned above, total absorptive capacity of absorbent cores 28 should adapt with design load and diaper use occasion.If diaper 20 is used for the body fluid volume of wearer discharge in many time, such as between the operating period at night, the absorptive capacity of absorbent cores 28 should be complementary with this purposes.Since bigger in the useful load of diaper during the ight than the diaper useful load between the operating period on daytime, the higher absorptive capacity so the diaper absorbent cores that wears night will suit.Otherwise in the lower time, as between the operating period on daytime, the absorptive capacity of absorbent cores 28 needn't be so high in the body fluid volume of wearer discharge.So, with respect to the absorptive capacity of ight diaper, the disposable diaper absorbent cores that the wears daytime lower absorptive capacity that should suit.

Handling the uncontrolled person of infancy stage and other uncontrolled persons' method for optimizing, is during they discharge less body fluid volume, as between the operating period on daytime, for they use first disposable diaper that a predetermined absorptive capacity is arranged.During the body fluid volume that wearer is discharged is more, as between the operating period at night, after it removes first disposable diaper on one's body, dress second disposable diaper for user with predetermined absorptive capacity bigger than first disposable diaper absorptive capacity.

The absorptive capacity of ight diaper is bigger with the absorptive capacity of diaper than daytime.The absorptive capacity of ight diaper suitable than daytime with the absorptive capacity of diaper greatly about at least 20%, preferably greatly about at least 50%, preferably greatly about at least 75%.In special preferred embodiment of the present invention, the absorptive capacity of ight diaper than daytime with the absorptive capacity of diaper greatly about at least 100%.

Similar to the uncontrolled person of present processing infancy stage and other uncontrolled persons' practical situation, disposable diaper is changed once usually at least by day.The replacing of a diaper can cause by multiple reason, as damp, and daily habits (time of day), the activity on daytime, or bowel movement.Since by day will be continually changing babies' napkin more, so the absorptive capacity of disposable diaper usually is not fully utilized by day.Because change daytime continually, daytime, the diaper quantity of demand surpassed the diaper quantity of ight demand usually.

With the use of simplifying the user, there are a plurality of disposable diapers of different absorptive capacities to be packaged in the same packaging bag for convenience.Be packaged in the packaging bag than the ratio of low absorption capacity diaper, in about 1: 1 to 10: 1 scope with the quantity of higher absorption capacity diaper.Ratio than low absorption capacity diaper and the quantity of higher absorption capacity diaper is suitably about 5: 1, and about 4: 1 preferably, preferably about 3: 1.

With reference now to Fig. 2,, packaging bag 200 has the shape of parallelepiped usually, and has represented a packaging bag after filling, and is wherein holding the diaper of the compression that different absorptive capacities are arranged.Packaging bag 200 comprises 212, one egative films 213 of 211, one top flats of 210, one rear panels of an anter and lateral plate 214 and 220.Lateral plate 214 comprises along connecting line 217 together two

section

215 and 216 fixed to one another.Lateral plate 220 comprises along connecting line 223 together two

section
