The description of exemplary diaper embodiment

In Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5 and Fig. 6, show that exemplary diaper 20 is in its open and flat not contraction state before being formed trousers.Finished product trousers product is shown among Fig. 7, Fig. 8 and Fig. 9.

An end of exemplary diaper 20 can be constructed to front waist region 36.Vertically relative end can be constructed to back waist region 38.The mid portion of the diaper 20 of longitudinal extension can be constructed to crotch district 37 between front waist region 36 and back waist region 38.

The basic structure of diaper 20 comprises base 100.In the front waist edge 136 that base 100 has a horizontal expansion in the front waist region 36 and the back waist region 38 vertically relatively and the back waist edge 138 of horizontal expansion.Left side edge 137a and one that base 100 has a longitudinal extension laterally relatively and the right side edge 137b of longitudinal extension, two sides of base longitudinal extension between front waist edge 136 and back waist edge 138.Base 100 has inner surface 102 and outer surface 104.Base 100 also has a longitudinal axis 42 and an axis of pitch 44.Longitudinal axis 42 extends through the mid point of front waist edge 136, and passes the mid point of back waist edge 138.Axis of pitch 44 extends through the mid point of left side edge 137a, and passes the mid point of right side edge 137b.Longitudinal extension and laterally opposing side flaps 147a and 147b in greater detail below exemplary base 100 shown in Figure 1 also has.The part of the formation egative film of base and flank (comprising the side barriers and the hoop wing) is available to comprise that one or more layers fleece (being " base fleece " in this article) forms.One or more layers of formation base fleece 149 can be the water impermeable.Each layer of formation base fleece 149 can have different lateral extent perhaps can be almost consistent on width.And said one or more layers of base fleece 149 and formation base fleece 149 can be horizontal and/or vertically successive.

The part of base 100 or all can be processed into is extensible to greater than the material of the processing base degree of the intrinsic ductility of egative film 26 for example.In order to make base 100 during wearer movement, can conform to wearer's health, additional extensibility possibly be desirable.Why additional extensibility possibly be desirable; Also be front waist region 36, back waist region 38 or this two lumbar regions that for example can stretch base 100 for the user of the diaper 20 that allows to be included in the base 100 that has specific dimensions before extending; So that the additional body covering to the wearer with different stature sizes to be provided; That is, make diaper be suitable for individual wearer.As long as crotch district 37 is stretched over the lumbar region and compares lesser extent, this type of stretching, extension of lumbar region can make diaper have the general hourglass shape, and when diaper 20 is worn, gives its fit outward appearance.In addition, reduce to minimumly for the cost that makes diaper, additional extensibility possibly be desirable.For example, only enough quantity of material of otherwise making the less relatively diaper that lacks this ductility can be used to make the diaper that can stretch with abundant covering wearer, and it is to wearer's the stickiness stickiness greater than inextensible less diaper.

The part of base 100 in front waist region 36 and/or back waist region 38 can be processed into and laterally be extensible to a certain maximum ductility; Said maximum ductility makes the lateral extension of each part to its maximum ductility in front waist region 36, back waist region 38 and crotch district 37 give base 100 hourglass shape greater than the maximum ductility of another part of base 100 in crotch district 37.As the exercise question that is filed on January 23rd, 2009 is the United States Patent (USP) sequence 12/358 of " Extrusion Bonded Laminates for Absorbent Articles "; Disclosed in 962, the fibroreticulate one or more layers of base can be included in layered product can provide the extension of desired amount and the elastomer thin film of restoring force between the operating period.As above mentioned, lateral extensibility can realize through elastomer thin film being incorporated in the fibroreticulate one or more layers of base.Can be used for the fibroreticulate one or more layers many suitable elastic materials of base and (for example comprise synthetic rubber or natural rubber; Cross-linked isoprene, polybutadiene and their saturated pattern (after the hydrogenation) and polyisobutylene), based on the thermoplastic elastomer (TPE) of segmented copolymer; Such as comprise with polystyrene block (for example; Styrene-isoprene-phenylethene, s-B-S, styrene-ethylene/butylene-styrene, styrene-ethylene/propylene-styrene and styrene-butadiene/isoprene-styrene comprises their hydrogenant and unhydrided form) the rubber elastomer block of combined polymerization those, the thermoplastic elastomer (TPE) based on polyurethane, polyester, polyetheramides, comprise polyethylene and polyacrylic elastomeric polyolefin, elastomeric polyolefin blend and their combination.

For example; Can be used for one group of block copolymer that useful elastomer polymer is vinyl arlydene and conjugate diene monomer in the base fleece; For example AB, ABA, ABC or ABCA block copolymer; Wherein the A segment can comprise arlydene such as polystyrene, and B and C segment (for comprising segmental those embodiments of B and/or C) can comprise such as diene such as butadiene or isoprene.The elastomer polymer that upgrades like one category is vinyl arlydene and the monomeric block copolymer of hydrogenated olefins; For example AB, ABA, ABC or ABCA block copolymer; Wherein the A segment can comprise arlydene such as polystyrene, and B and C segment (for comprising segmental those embodiments of B and/or C) can comprise such as saturation of olefins such as ethylene, propylene or butylene.The block copolymer resin that is fit to is easy to get from KRATON Polymers, Houston, Texas; Dexco ^TMPolymers LP (Planquemine, Louisiana); Or Septon ^TMCompany (America, Pasadena, Texas).

The useful elastomer polymer of another group that can be used in the base fleece is the alkylene elastomer.In one embodiment, elastomer thin film comprises polyolefin elastomer (POE).The instance of polyolefin elastomer comprises olefin block copolymers (OBC), and it is poly elastomer copolymer, with trade name INFUSE ^TMBe sold by The Dow Chemical Company (Midland, Michigan).Other instance of polyolefin elastomer comprises polypropylene and poly copolymer; Be sold by ExxonMobil Chemical Company (Houston with trade name VISTAMAXX

; Texas) and/or with trade name VERSIFY be sold by Dow Chemical (Midland, MI).

With regard to the fibroreticulate elastomer thin film of base part, can with other polyblends in the compositions to strengthen desired characteristic.For example, can LLDPE be added in the film composite with viscosity that reduces polymer melt and the machinability that strengthens extrusion film.Can add high density polyethylene (HDPE) to prevent the degraded that takes place that ageing-related of other polymer.Found that polypropylene can improve elastomeric robustness and improve the repellence of thin film to boring a hole and tearing.In addition, (for example, ADFLEX derives from the toughness that LyondellBasell Industries (Laporte, TX)) can be used for increasing thin film, as disclosed among the WO 2007/146149 based on polyacrylic thermoplastic elastomer (TPE) reactive blending thing.

The basic structure of diaper 20 also comprises the absorbent assembly 200 that can be attached to base 100.Absorbent assembly 200 has the leading edge 236 of a horizontal expansion in front waist region 36 and in back waist region 38 one vertically relatively and the back edge 238 of horizontal expansion.Left side edge 237a and one that absorbent assembly 200 has a longitudinal extension laterally relatively and the right side edge 237b of longitudinal extension, two sides of absorbent assembly are longitudinal extension between leading edge 236 and back edge 238 all.Absorbent assembly 200 has inner surface 202 and outer surface 204.Absorbent assembly 200 can be symmetrical set with respect in longitudinal axis 42 and the axis of pitch 44 one or two.As other a kind of selection, absorbent assembly 200 can be with respect to one or two the asymmetric setting in longitudinal axis 42 and the axis of pitch 44.For example, the absorbent assembly shown in Fig. 1 200 is symmetrical set with respect to longitudinal axis 42 and with respect to axis of pitch 44 asymmetric settings.Specifically, the absorbent assembly shown in Fig. 1 200 is towards front waist region 36 asymmetric settings.

370 and 390 can be attached to inner surface and/or the inner surface of absorbent assembly 202 and/or the upper surface 613a and the b of flank 147a and b of base 102.

During using diaper 20 (being configured to the diaper of pull-on pants specifically), diaper 20 can upwards be pullled waist along shank and on wearer's buttocks.There are several kinds of factors can influence the wearing property that is prone to of pull-on diapers.At first, wearer or nursing staff should be easily pass leg opening with wearer's shank.Second; Abdominal stretch panels 360,370,380 and 390 should have acceptable applied force (that is, make wearer or wearer's nursing staff can stretch abdominal stretch panels 360,370,380 and 390 and diaper upwards moved on wearer's the buttocks and needn't too hard power).For example pull up and down for the child of toilet training of trousers with the strength of oneself for nursing staff and/or wearer, applied force is crossed ambassador and is used diaper 20 difficulty more.At last; The power of wearing or lasting applying power that abdominal stretch panels 360,370,380 and 390 should provide proper level are (promptly; The power that abdominal stretch panels 360,370,380 and 390 is applied on the waist during wearing; Thereby necessary lasting stickiness is provided, comprises keeping position, applying and the liner of diaper 20, and do not make the skin mark) at waist.

Like Fig. 7, Fig. 8 and shown in Figure 9, when diaper 20 is worn on the lower torso of a wearer last time, the front waist edge 136 of base 100 and the waist of back waist edge 138 around the wearer, and simultaneously

chassis side

137a and 137b around wearer's shank.Simultaneously, crotch district 37 can be between wearer's shank, and absorbent assembly 200 passes crotch district 37 from front waist region 36 and extends to back waist region 38.

Base is described

Base 100 comprises water impervious egative film 26.Egative film 26 forms the outer surface that expection is placed towards any clothes that is worn on the diaper 20.Many materials of making egative film 26 that are suitable for are known by people, comprise polyethylene and other polyolefin film.The multiple field egative film is such as thin film 30 and the layered product of non-woven material 31 or the layered product of a plurality of non-woven layers, the also applicable egative film 26 of doing.This type of egative film can be oriented to the outside that makes non-woven material 31 be arranged on thin film, like Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5 and shown in Figure 6, to provide than through using thin film 30 as the outermost sensation and the outward appearance that more are similar to cloth that outermost layer was provided.The multiple field egative film 26 for example layered product of thin film 30 and non-woven material 31 also can be suitable for non-woven material 31 is arranged on inner so that the skin of thin film 30 with the wearer is separated; Perhaps non-woven material 31 is arranged on outside and inside, makes thin film 30 be clipped in wherein.In addition, the non-woven material 31 and the thin film of multiwalled layered product can have different widths for 30 layers, and for example thin film 30 can be wider than non-woven material 31 or as other a kind of selection, non-woven material 31 can be wider than thin film 30.

Shown in Figure 36-43, base fleece 149 can form by a plurality of, comprises central plate 726 and horizontal relative lateral plate 60.Central plate 726 can be formed by identical or different material type with lateral plate.For example, central plate 726 can comprise the impermeable material of water vapour, and lateral plate can comprise the material of vapor permeable.The exemplary materials that is applicable to lateral plate 60 comprises polyolefin film, micropore or other breathable formed film, breathable monolithic film membrane and hydrophobic nonwovens.Suitable hydrophobic nonwovens comprises SM (spunbond-as to melt and spray), SMS (spunbond-as to melt and spray-spunbond) and SMMS (spunbond-as to melt and spray-as to melt and spray-spunbond) composite.Can select the material of the lateral plate 60 of vapor permeable, with the overall economic effect and the function of equilibrium product.For example, the relative more expensive non-woven material that has a relative higher basis weights can be provided for the gratifying water impenetrability level of monolayer flank structure.As other a kind of selection, have the relative more cheap non-woven material of relatively low basic weight, be the essential water impenetrability level that just provides when doubling only when it, therefore need more large-area relatively material.And for example, microporous membrane can provide the combination of the relative optimization of water impenetrability and material cost.In multiple field base fleece 149 configurations, one of them can comprise central plate 726 and the lateral plate that forms the first multiple-piece layer said layer.The first multiple-piece layer can be linked to individual course, and said individual course can comprise single continuous material or can be the fibroreticulate form of second multiple-piece.This type of embodiment comprises the multiple-piece thin layer of the lateral plate with the impermeable central plate 726 of water vapour and vapor permeable.The multiple-piece thin layer can be in turn laminated on the integral type non-woven material to form multiple field base fleece 149.

Shown in Figure 36-43, exemplary base 100 has longitudinal extension and horizontal relative

breathable flank

147a and 147b, and it is set at inwardly facing the wearer and contacting on wearer's the inside of diaper 20.Through laterally inwardly, that is, form flank, thereby form two

corresponding flank

147a and 147b and and

side

137a and 137b of base 100 to the part of the lateral plate that comprises vapor permeable 60 of longitudinal axis 42 folding base seats 100.The lateral plate 60 of base 100 can laterally inwardly be folded to form flank.As other a kind of selection, collapsible base makes each flank include the part of corresponding lateral plate 60 and central plate 726.In each configuration, because each flank includes at least a portion of the lateral plate of corresponding vapor permeable, so at least a portion of each flank is a breathable.As other a kind of selection, lateral plate can be water vapour impermeable and central plate 726 and can be vapor permeable.

Like Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5 and shown in Figure 6, exemplary base 100 has longitudinal extension and horizontal opposing side flaps 147, and it is set at the inside wearer of facing of diaper 20 and contacts on wearer's the interior section.Can be through laterally inwardly, that is, form flank 147 to the part of longitudinal axis 42 folding base seats 100, thereby form the corresponding flank 147 and side 137 of base 100.As other a kind of selection, shown in figure 31, flank 147 can through at each respective side edge 137 place of base 100 or contiguous said side one or more extra plays be attached to base 100 form.

Each flank 147 all has proximal 157.In exemplary diaper shown in Figure 1 20, flank 147 is overlapping with absorbent assembly 200, and promptly proximal 157 laterally is positioned at the inboard of the respective side edge 237 of absorbent assembly 200.A kind of like this overlapped configuration can be ideal, so that diaper 20 has the more perfect outward appearance of the outward appearance of giving than non-overlapped configuration.As other a kind of selection, flank 147 can be not overlapping with absorbent assembly 200.

In the flank 147 each all can link in the district 152 at the flank that the flank of the vertical trend in the front waist region 36 links the vertical trend in district 151 and the back waist region 38 and be connected on the inner surface 102 of base 100.

In exemplary base shown in Figure 1 100, flank 147 also can be close to front waist edge 136 and link in the district 153 and contiguous back waist edge 138 links in the district 154 at the flank of vertically relative horizontal trend and is attached on the inner surface 102 of base 100 at the horizontal flank of trend.

Therein the corresponding front waist edge 136 of the leading edge 236 of absorbent assembly 200 or back edge 238 and base 100 or back waist edge 138 overlaps and flank 147 and absorbent assembly 200 eclipsed embodiments in; Replace being linked on the inner surface 102 of base 100 or in addition, can flank 147 be attached on the absorbent assembly 200.

Base 100 comprises that multiple field base fleece 149 is for example in the embodiment of thin film 30 and the layered product of non-woven material 31 therein; Non-woven material 31 is the width of complete extend through thin film 30 in the horizontal; Perhaps as other a kind of selection, non-woven material 31 can have less than or greater than the width of 30 layers of thin film.In the embodiment of width (lateral extent) less than the width of thin film 30 of non-woven material 31; Being folded to form that part of of flank 147 and can forming for 30 layers by thin film separately of base fleece 149; Perhaps can form (in other words for 30 layers by thin film basically; For multiwalled base fleece 149, non-woven material 31 can cross whole outer surface 104 and extend to opposed side edges 137b from a chassis side 137a; Perhaps as other a kind of selection, non-woven material 31 can wrap up chassis side 137a and b and cover the part of flank 147a and b.Non-woven material 31 has in the embodiment greater than the width (lateral extent) of the width of thin film 30 therein; Being folded to form that part of of flank 147 and can being made up of for 31 layers non-woven material separately of base fleece 149 perhaps can be made up of for 31 layers non-woven material basically.In addition, the non-woven material 31 of multiple field base fleece 149 is the length of complete extend through thin film 30 in the vertical, and perhaps as other a kind of selection, non-woven material 31 can have the longitudinal extent less than 30 layers of thin film.Non-woven material 31 has in the embodiment less than the length (longitudinal extent) of thin film 30 therein, and the part that in front waist region 36 and/or back waist region 38, is covered by non-woven material 31 of base 100 can not covered by abdominal stretch panels 360,370,380 and 390.

Like Figure 23-28, shown in 50 and 51, one or more in each layer of base fleece 149 (for example, thin film 30 with non-woven material 31) comprise one or more pattern area for example 615 and 618a and 618b.First pattern area 615 can form contrast (promptly with other pattern area; When with another pattern area for example the second pattern area 618a and the 3rd pattern area 618b it shows difference relatively the time), perhaps other part with other part of egative film 26 or the surface observed of diaper 20 (diaper of keeping intact that detects by an unaided eye) for example comprises that the abdominal stretch panels 360 of the 4th pattern area 660 and the abdominal stretch panels that comprises the 5th pattern area 680 380 form contrast.Pattern area 615,618a, 618b, 660 and 680 can comprise pattern and free of discontinuities or the painted areas of being interrupted of combination (for example, the eyes that can be in first graphic elements and the identical image of the hair in people's image can be the second graph element), the graphic elements of a graphic elements or single graphic elements.For example, various pattern area can be made up of the continuous repeat patterns that on the direction of longitudinal extension, forms.As other a kind of selection; Pattern area 615,660 and 680 can comprise the graphic elements (not shown); Said graphic elements is designed to the diaper 20 of concrete size or provides and concrete graphic language that concrete zone (for example, the front waist region 36 of diaper 20, back waist region 38 or crotch district 37) is associated.This type of graphic elements is often referred to as the pitch figure, and the meaning is that the pitch (that is length) of this pattern and diaper 20 or the part with the diaper pitch connects of diaper 20 link or be associated.In addition, two or more pattern area can partly cover to form the mixed pattern district each other mutually.

In certain embodiments of the invention; Especially those wherein the part of base fleece 149 be folded to form in the embodiment of horizontal opposing side flaps 147a and b of longitudinal extension; Pattern area 615 extensible whole outer surface 104 (or on said outer surface, can be observed) with the covering absorbent article, and cover flank 147a and the upper surface 613a of b and the part (or on said part, can be observed) of b.Understand that when being printed on 30 last times of thin film, pattern area can see through the outer surface 104 that forms egative film 26 or the upper surface 613a of flank 147a and b and non-woven material 31 quilts of b seen that wherein non-woven material 31 can be adhered on the thin film 30 from the outside.In this case, the cause of (for example, thinness, the transparency, opaque etc.) because the characteristic of non-woven material 31, pattern area 615 and 618 will be visible.

In one embodiment, first pattern area 615 extends laterally to horizontal opposed side edges 137b from a side 137a of base 100.Except the outer surface 104 of covering base 100, possibly expect that also the side 137a and the b that make first pattern area 615 wrap base 100 also laterally inwardly extend to cover at least a portion of flank 147a and b.Select as another one, flank 147a and b can comprise the second and the 3rd pattern area 618a and b respectively.In certain embodiments; The visible part that pattern area 615,618a and b, 660 and 680 not only can be absorbent article provides the aesthetic vision outward appearance of pleasant; But also can flank 147a and b and egative film 26 be made a distinction; Perhaps with the each several part of flank 147a and b and itself make a distinction (for example, will bind round the wing 631 and make a distinction), make during the wearing of diaper 20, to help wearer or nursing staff correctly to place flank 147a and b with side barriers 633.For example, referring to Figure 23 and 24, egative film 26 has first pattern area 615, and it rises and falls and end at the right folding line 608b of base fleece 149 along left folding line 608a of base fleece 149.Fold line 608a and b are that base fleece 149 is folded to form the flank 147a of egative film 26 and the line of b and side 137a and b along it.Second pattern area 618 can extend to not folding right side edge 155b (when base 100 was folded to form flank 147a and b, it became the proximal 157b of flank 147b) from the right side edge 619 of first pattern area 615.As other a kind of selection, shown in Figure 25 and 26, first pattern area 615 can from or certain of the left side edge 137a of proximate base 100 a bit extend to or contiguous right side edge 137b certain a bit, make flank 147a and b become visually different element.When existing; The each several part that first pattern area 615, the second pattern area 618a and the 3rd pattern area 618b all can make flank 147a and b (for example; The hoop wing 631 and side barriers 633) visually more different; Particularly when having adopted the second elastic strands 168a and b; Make two hoop parts (that is, the merging of the first elastic strands 167a and b and the second elastic strands 168a and b, wherein the proximal 157a of the first elastic strands 167a and b and flank 147a and b and b direct neighbor and the second elastic strands 168a and b are oriented to side 137a and the b direct neighbor with base 100) visually become outstanding.Be to be understood that; Shown in Figure 27 and 28; Also can be through first pattern area 615 is compared outstanding two hoop parts with flank 147a and b, flank 147a and b do not comprise graphic elements and therefore do not comprise the pure color (monochrome) and the texture of the egative film 26 that constitutes it in the second or the 3rd pattern area 618a and b.In aforesaid multiple-piece base fleece 149 structures, pattern area 615 can be arranged on the central plate 726, and pattern area 618 can be arranged on the lateral plate 60.

Shown in Figure 50 and 51, abdominal stretch panels 360,370,380 and 390 comprises pattern area 660,670,680 and 690, is respectively the 4th, the 6th, the 5th and the 7th pattern area.In one embodiment, pattern area 660 and/or 680 can comprise only visible graphic elements on the outside of absorbent article (when quilt is worn), and promptly the remainder of the visual outside of goods (when quilt is worn) does not have extra graphic elements.In an alternative embodiment; Pattern area 660 and/or 680 on the visual outside of abdominal stretch panels (when quilt is worn) can comprise polychrome graphic elements or pattern area, and the remainder of the visual outside of absorbent article (when quilt is worn) can comprise monochromatic pattern area.In another alternative embodiment, the pattern area 660 of abdominal stretch panels and/or 680 can comprise monochromatic pattern area, and pattern area 615 or 618 can comprise the multicolor patterns district.As other a kind of selection, pattern area 660 and/or 680 can comprise monochromatic pattern area or multicolor patterns district and/or polychrome graphic elements, and can be combined with the egative film that does not comprise graphic elements, monochromatic pattern area or monochrome or polychrome graphic elements.

In addition; The pattern area 660 that is arranged on the abdominal stretch panels in the front waist region can comprise the graphic elements in the front of being intended to indicate absorbent article; And the pattern area 680 that is arranged on the abdominal stretch panels in the back waist region can comprise the graphic elements at the back side of being intended to indicate absorbent article, thereby helps nursing staff or the directed exactly said product of wearer so that wear.Equally, the egative film that comprises the pattern area 615 that is arranged in the front waist region can comprise the graphic elements in the front of being intended to indicate absorbent article, and the pattern area 615 that is arranged on the egative film in the back waist region can comprise the graphic elements at the back side of being intended to indicate absorbent article.

Between vertically the opposing side flaps binding was distinguished, the proximal 157 of flank 147 kept free, that is, be not attached to the inner surface 102 of base 100 or be not attached to absorbent assembly 200.Equally vertically between the opposing side flaps binding district; Each flank all can comprise one or more (specifically; Each flank comprises one, two, three or four strands) wing elastic gathering members that can vertically extend, the proximal that said member can be adjacent to flank through any method in the method for much knowing links.Each this type of wing elastic gathering members all can be on its whole length or at only a part of enterprising joining line of its length.For example, this type of wing elastic gathering members can be only be positioned at or near its vertically relatively end link, then do not link in the middle of its length.This type of wing elastic gathering members can be arranged in the crotch district 37, and may extend in front waist region 36 and the back waist region 38 one or two.For example, in exemplary base shown in Figure 1 100, the proximal 157 that elastic strands 167 can be adjacent to each flank 147 links, and extends to front waist region 36 and back waist region 38 among both.

Can each wing elastic gathering members be encapsulated in the folding chirring.For example, in Fig. 4 and exemplary base 100 shown in Figure 5, each in the elastic strands 167 all can be encapsulated in the proximal 157 formed chirrings 170 that are adjacent to corresponding flank 147.As other a kind of selection, can one or more wing elastic gathering members be interposed between two layers of base, perhaps can be attached on the surface of base 100 and keep exposing.

When being stretched, the wing elastic gathering members that is adjacent to each flank proximal setting makes side flap edge can extend to the flat uncontracted length of base, and for example the length of base 100 is as shown in Figure 1.When allowing to relax; Wing elastic gathering members contract is to lift front waist region 36 and back waist region 38 toward each other; Thereby make diaper 20 bend to " U " shape, wherein the inside of " U " shape can by diaper 20 be intended to form towards the part that wearer's health is placed.Because each in the proximal 157 all links at the flank that vertically moves towards and keeps free between the district 151 and 152, so the contractility of elastic strands 167 is lifted from the proximal 157 of flank 147 inner surface 102 of base 100.When diaper 20 was in relaxed state, proximal 157 this mentioned flank 147 is raised to the position that the side 237 of contiguous absorbent assembly 200 plays the side barriers effect.

Like Fig. 1,2,4,5,18, shown in 19 and 20; One or more (specifically, each flank comprises one, two, three or four strands) the second elastic strands 168a and b can or contiguous chassis side 137a and the b place that wherein it is folded to form the base 100 of flank 147a and b link.When allowing when lax, the side 137a that the second elastic strands 168a and b can tighten up base 100 and b are with formation side barriers 633a and b and play the effect that stops urine and feces leakage.Side 137a and b that it is folded to form the base 100 of flank 147a and b be can be close to wherein and passage 621a and b formed; Making that the part of formation passage 621a and b of base fleece 149 is most of keeps not adhering to from one's body or do not adhere on the second elastic strands 168a and the b; Particularly in each relative

lumbar region

36 and 38; The second elastic strands 168a and b make the second elastic strands 168a and b float in the cavity of passage 621a and b, so that can retract to its gummed length during manufacture rapidly after cutting diaper 20 by scale.

Like Fig. 2,4,5,18, shown in 19 and 20, flank 147 can be shaped as the hoop wing 631 and side barriers 633.Specifically, side barriers connecting piece 630 can be oriented between first elastic strands 167 and second elastic strands 168.Side barriers connecting piece 630 has directly and coupling effect the degree of depth of the hoop wing 631 and the size of side barriers 633 with respect to the placement of longitudinal axis 42.For example, when laterally inwardly moving side barriers connecting piece 630, the degree of depth of the hoop wing 631 reduces and the size of side barriers 633 increases.Otherwise shown in figure 18, when laterally outwards mobile side barriers linked 630, the degree of depth of the hoop wing 631 increased and the size of side barriers 633 reduces.For various application, the degree of depth and/or the size that can adjust the hoop wing 631 and side barriers 633 are to provide enhanced functional.In this type of embodiment, shown in figure 19, have been found that the hoop wing 631 degree of depth reduce and side barriers 633 is used to provide for the pull-on pants type more greatly and better used simplification.This configuration increases the size (not shown among Figure 19) of leg opening, and the wearer can more easily be got in the diaper 20.In another embodiment, have been found that the size that increases the degree of depth of binding round the wing 631 and reduce side barriers 633 provides the capacity perceptibility of improved leakage protection property and increase.

From the proximal 157 of flank 147 measure to the degree of depth of the hoop wing 631 of side barriers connecting piece 630 can be about 2cm to about 7cm, about 2.5cm to about 6.5cm, perhaps about 3cm about 6cm extremely.From the proximal 157 of flank 147 measure to the length of the flank 147 of the side 137 of base 100 can be about 4.5cm to about 9.5cm, about 5cm to about 8.5cm, perhaps about 5.5cm about 7.5cm extremely.As other a kind of selection, shown in figure 20, can use second counter-lateral quadrents barrier connecting piece 630c and the d, make the hoop wing 631 can adjust flank 147 height and do not influence the height of side barriers 633.Passage 634a and b can form between side barriers connecting piece 630a and c and/or 630b and d, and can comprise that being arranged on one or more added resilience tightens up member/strand 635a and b.

Each respective side edge 137a that just wherein passes through at base 100 and b place or contiguous said side are with extra play (for example; Thin film 30 and/or non-woven material 31) be attached to the embodiment that base 100 forms flank 147; The second elastic strands 168a and b can (for example be orientated and be attached at each layer; Thin film 30 and non-woven material 31) between, referring to Figure 32.Said layer (for example, thin film 30 and non-woven material 31) also can form passage (for example, 621a and b) and the function that is associated with it as stated is provided.

Shown in Figure 44-49, the basic structure of diaper 20 comprises base 100.In the front waist edge 136 that base 100 has a horizontal expansion in the front waist region 36 and the back waist region 38 vertically relatively and the back waist edge 138 of horizontal expansion.Finished product base 100 has the preceding folded side fragment 133a and the 133b of longitudinal extension in front waist region; The back folded side fragment 133c and the 133d that in back waist region, have vertically relative longitudinal extension; And the cutting side fragment 135 that in the crotch district, has longitudinal extension at least, each in the said cutting side fragment 135 all connects corresponding front and back folded side fragment 133.Combine, corresponding folding side fragment 133 forms composite side edges 137 with cutting side fragment 135, and it connects front waist edge and back waist edge.Base 100 has inner surface 102 and outer surface 104.Base 100 also has a longitudinal axis 42 and an axis of pitch 44.Longitudinal axis 42 extends through the mid point of front waist edge 136, and passes the mid point of back waist edge 138.Axis of pitch 44 extends through the mid point of left side edge 137a, and passes the mid point of right side edge 137b.Longitudinal extension and laterally opposing side flaps 147a and 147b in greater detail below exemplary base 100 shown in Figure 44 also has.

In the finished product diaper, base has roughly " hourglass shape " shape, as in the exemplary diaper shown in Figure 44 20.In order when diaper 20 is worn, to give its fit outward appearance, this type of non-rectangular shape possibly be desired.To cosily be fitted in the sensation between wearer's shank in order to give diaper 20, this type of non-rectangular shape also possibly be desired.

Horizontal relative part through removing base 100 from crotch district 137 at least gives base 100 hourglass shape to form laterally relative side recess 139.The formation of this side recess 139 makes it be positioned at and the lateral dimension that is close to axis of pitch 44 places is positioned at and is close to the lateral dimension at front waist edge 136 places less than it in the base; And be positioned at and be close to the lateral dimension at back waist edge 138 places less than it; That is, make base ratio in crotch district 37 narrower at edge of

waist

136 and 138 places.

Profile through removing the formed side recess 139 of folding material along cutting side fragment 135 is by the segmental contour limit of this cutting side.This profile can be continuously arciform.As other a kind of selection; This profile can be for by two vertical relative arcuate sections 140 and the roughly straight mid portion 141 formed complexs that are connected said arcuate section; Therefore not continuously arciform, as in the exemplary diaper shown in Figure 44 20.Side recess 139 can be symmetrical set with respect to any or two in the longitudinal axis of base 100 42 and the axis of pitch 44.For example, in Figure 44, side recess 139 is shown as with respect to longitudinal axis 42 and axis of pitch 44 and all is symmetrical set.As other a kind of selection, side recess 139 can be with respect to any or two the asymmetric settings in longitudinal axis 42 and the axis of pitch 44.For example, side recess 139 can be symmetrical set and with respect to axis of pitch 44 asymmetric settings with respect to longitudinal axis 42, for example wherein side recess 136 skews towards the Attacking Midfielder edge.

Laterally relative part through removing base forms side recess 139, and vertical isolated fragment of folded side 133 is kept perfectly, and laterally moves and effusion diaper 20 to prevent any body excretions.Specifically, only preceding folded

side fragment

133a and 133b and back folded

side fragment

133c and 133d are kept perfectly.Remove sidepiece 142 and to form each side recess 139 the corresponding flank 147 and the lower floor of base are separated along each profile that cuts side fragment 135, thereby produce opening, body excretions can be overflowed through this opening.Therefore, base 100 comprises the continuous barrier connecting piece 630 of at least one longitudinal extension that is horizontally installed on each cutting side fragment 135 nearside.Each flank 147 all is attached to the lower floor of base 100 at barrier connecting piece 630 places.Each barrier connecting piece 630 is water impervious at least in the horizontal, thereby preferably is used as embankment to prevent laterally effusion in the gap of body excretions between preceding folded side fragment of vertically separating and back folded side fragment.

Can use single barrier connecting piece 630 to link each flank 147,, can use two or more barrier connecting pieces 630 to link each flank 147 perhaps as other a kind of selection.The one or more barrier connecting pieces 630 that are used for linking each flank can be described to form barrier link the district (that is, each flank all have its own barrier link distinguish).For example, in exemplary diaper shown in Figure 44 20, can use two laterally spaced barrier connecting pieces 630 to link each flank 147.And for example, can use single barrier connecting piece 630 to link each flank 147 in the exemplary diaper 20.And for example, can use four laterally spaced barrier connecting pieces 630 to link each flank 147 in the exemplary diaper 20.Use single barrier connecting piece 630 can help to minimize the cost of diaper 20 to each lateral plate 147.On the other hand, thus use more than one barrier connecting piece 630 to make fluid can pass the horizontal effusion that helps to prevent body excretions under himself the situation not exclusively continuously to each lateral plate 147 a side seal.

Barrier connecting piece 630 can be orientated to and be roughly parallel to longitudinal axis 42 and parallel, and is shown in figure 44.Barrier connecting piece 630 can be constructed to mirror image each other.

Barrier connecting piece 630 can form in the following manner: the combination of hot adhesion, pressure bonding, hot adhesion and pressure bonding, ultrasonic bonding, adhesives or known in the art is used to form laterally water impervious agglutinating any alternate manner or mode makes up.Each barrier connecting piece 630 all can extend to back waist edge 138 from front waist edge 136, and is shown in figure 44.As other a kind of selection, barrier connecting piece 630 can extend not farly in the vertical.For example, barrier connecting piece 630 can extend to such an extent that only extend the same far with corresponding cutting side fragment 135 in the vertical.

The barrier connecting piece 630 initial extensible sidepieces that pass base 100, said sidepiece finally are removed to form side recess 139.After forming side recess 139, keeping vertically, successive exemplary barrier connecting piece 630 also is illustrated in the finished product exemplary diaper 20 of Figure 44 and Figure 49.

Barrier connecting piece 630 can be substantially linear in form, and is shown in figure 44.As other a kind of selection, barrier connecting piece 630 can be curve in form.For example; Barrier connecting piece 630 can have and cut the roughly concentric profile of profile of side fragment 135, thereby " following " cutting side is segmental from being positioned at or the extremely corresponding correspondence back folded side fragment 133c of point of contiguous corresponding preceding folded

side fragment

133a or 133b or the profile of 133d.In this configuration, preceding folded side fragment, side seal and the segmental combination of back folded side can form the vertically continuous barrier that prevents body excretions horizontal mobility between front waist edge and back waist edge.As another selective replacement scheme; Wherein preceding folded side fragment, side seal and the segmental combination of back folded side can form the vertically continuous barrier that prevents the body excretions horizontal mobility; Barrier connecting piece 630 can sufficiently widely extend to folded side fragment 133, exemplary side seals for example shown in Figure 49 with the horizontal inboard from cutting side fragment 135.

Each barrier connecting piece 630 all can be shaped as at least ten times the narrow relatively bar that length is width, exemplary side seals for example shown in Figure 44.As other a kind of selection, each barrier connecting piece 630 all can be shaped as the relatively wide band of length less than ten times width, exemplary side seals for example shown in Figure 49.

And/or each side 137 place of proximate base, front waist region 36 links together with back waist region 38 and has the finished product trousers product of waist opening 10 and two leg openings 12 with formation.This connecting piece can have the form of latasuture 115.This latasuture forms at the recline position of outer surface of another lumbar region of the overlapping inner surface that makes a lumbar region in lumbar region therein.In another form, latasuture forms at the position of the side adjacency in the lumbar region therein.In another form, the inner surface or the outer surface of lumbar region promptly are in the banded position formation of so-called flange in face-to-face contact to latasuture therein.This type of flange binding is shown among Fig. 7, Fig. 8 and Fig. 9.

Latasuture forms at the recline position of outer surface of another lumbar region of the overlapping inner surface that makes a lumbar region in lumbar region therein.In such embodiment, can an enclosed member 700 be arranged on the inner surface of flank, simultaneously another enclosed member 700 is arranged on the outer surface of egative film.In an alternative embodiment, the latasuture position of the side adjacency in the lumbar region therein forms.In such embodiment, but be arranged on the outer surface of egative film in enclosed member 700 pro-and latter two lumbar region and/or in front waist region and back waist region, be arranged on the inner surface of flank, make it cross relative lumbar region from a lumbar region.In another embodiment, the inner surface or the outer surface of lumbar region promptly are in the banded position formation of so-called flange in face-to-face contact to latasuture therein.This type of flange binding is shown among Fig. 7, Fig. 8 and Fig. 9.

In other embodiments, enclosed member 700 can be used to after goods are worn wearer, adjust goods.The second enclosed member (not shown) plays the effect of the tension force (that is, " holding ") that after using, increases in the waist hoop, so that the enhanced lasting stickiness of goods is provided.The second enclosed member (not shown) can comprise the fastener of any kind known in the art and can be associated with the tensile stretching element that helps to increase in the waist hoop.The second enclosed member (not shown) can be close to that one in the main enclosed member 700 is provided with or can with the one manufacturings in the main enclosed member 700.The purpose of the second enclosed member (not shown) is to make user can adjust the stickiness of goods.Should be appreciated that can be promptly main with a plurality of enclosed members, second, third enclosed member etc. incorporate in the assembly of the latasuture 115 that forms refastenable one or whole in.

In addition, should be appreciated that enclosed member 700 need not have unlimited useful life, but but separately with again binding is just enough several times at typical useful life's scope adjoining land of absorbent article with the banded enclosed member 700 of the mode of refastenable.It should also be understood that; The firm degree of actual fastening is said on absolute meaning and can be reduced significantly from fastening to fastening again; If but the fastening intensity again of gained enough is used for the application target of fastening system, then this reducing is not " the essence deterioration " of fastener performance just.

The part of base 100 or all can be processed into is extensible to greater than one or more materials of processing base degree of the intrinsic ductility of egative film 26 for example.In order to make base 100 during wearer movement, can conform to wearer's health, additional extensibility possibly be desirable.Additional extensibility also possibly be desirable; For example be included in front waist region 36, back waist region 38 or this two lumbar regions that the user of diaper 20 that has the base 100 of specific dimensions before the elongation can stretch base 100 in order to make; Thereby for the wearer of different stature sizes provides additional health to cover; That is, make diaper be suitable for individual wearer.As long as crotch district 37 is stretched over the lumbar region and compares lesser extent, this type of stretching, extension of lumbar region can make diaper have the general hourglass shape, and can when diaper 20 is worn, give its fit outward appearance.In addition, reduce to minimumly for the cost that makes diaper, additional extensibility possibly be desirable.For example, only enough quantity of material of otherwise making the less relatively diaper that lacks this ductility can be used to make the diaper that can stretch with abundant covering wearer, and it is to wearer's the stickiness stickiness greater than inextensible less diaper.

The part of base 100 in front waist region 36 and/or back waist region 38 can be processed into and laterally be extensible to maximum ductility; Said maximum ductility makes the lateral extension of each part to its maximum ductility in front waist region 36, back waist region 38 and crotch district 37 give base 100 hourglass shape greater than the maximum ductility of another part of base 100 in crotch district 37.In one embodiment; Base 100 (for example be positioned at abdominal stretch panels; Back/preceding inside/outside abdominal stretch panels 360,370,380 and 390) following and/or can be processed into the part of said abdominal stretch panels direct neighbor and laterally to be extensible to maximum ductility; Said maximum ductility is greater than another part of base 100 maximum ductility in crotch district 37 for example; Make each the lateral extension in these parts help diaper 20 being worn on wearer's the health: waist opening 10 can be extended putting wearer's hip, thereby and open and be orientated leg opening 12 in addition and make the wearer more effectively shank passed leg opening 12 through following mode to its maximum ductility.

Additional lateral extensibility in the base 100 can provide in many ways.For example, the material of processing base 100 can carry out pleating with the arbitrary method in many known methods.As other a kind of selection; All or part of of base can be interrupted activation to produce the elastic moulding material fleece of structuring class or to be similar to the United States Patent (USP) of announcing with people's such as Chappell name as on May 21st, 1,996 5; The moulding material fleece lamination body of those described in 518,801.In a further preferred embodiment, when the elongation that stands to apply on the direction that is being arranged essentially parallel to axis, web material of the present invention shows at least two remarkable different drag stages to the elongation that applies along at least one axis.But web material comprises the strain network with at least two zoness of different.One in the said zone is so shaped that it, will be in response to showing drag being arranged essentially parallel to the axial elongation that applies on the direction of axis before other regional major parts produce any significant drag to the elongation that applies.In the said zone at least one has the surface-pathlength greater than another regional surface-pathlength, and it is measured to be arranged essentially parallel to axis when not straining situation as being at material.The zone that shows long surface-pathlength comprises the rib linear element of one or more formation ridges and paddy, and said ridge and paddy extend beyond other regional planes.Web material shows first drag to the elongation that applies; Till the major part that in the elongation of said web material is enough to make the zone, has a longer surface-pathlength gets into the axis of elongation that applies; Web material shows second drag (that is the basic coplane of axis of elongation that, becomes and apply) to other elongation in view of the above.Total drag to elongation is higher than first drag to elongation that is provided by the first area.

This moulding material fleece comprises the zone of different horizontal expansions; Wherein original material through embossing or another kind of deformation method change producing roughly machine-direction oriented alternative ridge and the pattern of paddy, and between the zone of the change of horizontal expansion, comprise that also the not change of horizontal expansion is regional.The moulding material fleece can extend to that ridge and paddy receive the less power of essence on perpendicular to the direction of ridge at most and the point that flattens, and said power is less than extending beyond the required power of that point.Except lateral extensibility, the generation of aforesaid shaping laminate web provides improved texture and garment-like appearance and sensation for egative film 26.Distortion produces the garment-like pattern and in multiple field thin film 30 and non-woven material 31 laminate backsheet 26, improves the bulkiness of non-woven material 31 in thin film.

The exemplary fragment 300 of this type of moulding material fleece 305 is shown among Figure 52.This moulding material fleece 305 comprises the zone 310 of different horizontal expansions, and wherein original material changes to form the pattern of roughly vertical alternative ridge that moves towards 312 and paddy 314 with embossing or another kind of deformation method.Moulding material fleece 305 also comprises the not change zone 316 of the horizontal expansion between the zone 310 of the change of horizontal expansion.

A kind of like this shaped fibers net materials 305 can be surpassed its original dimension by extending transversely, same material is stretched over same degree when not being out of shape to compare, and only need apply less relatively power.Specifically, apply and be approximately perpendicular to ridge 312 and paddy 314 and many effects of directed opposite dispersion force comprise along the such moulding material fleece of the axis elongation between the opposite force and mainly produce the contractility that contends with in the zone 316 changing.Be elongated to and reach the drag that the ridge that wherein changes in the zone flattens with paddy and produced when beginning to produce the same degree of degree of drag at least and compare with being in the same material that does not change form, this drag is less relatively.Therefore, in to the useful ductility scope of the desired extending transversely pattern that is used for absorbent article, this type of moulding material fleece demonstrates to have and the similar extending character of traditional elastomeric material.Yet this type of moulding material fleece can elasticly be processed than cheap material by not having originally, therefore uses them aspect the cost of making absorbent article advantage being provided.

As other a kind of selection, (for example therefore looping mill rolling also gives the ductility of height to the activation continuously of the part of base, like United States Patent (USP) 5,366, described in 782 (the authorizing people such as Curro on November 22nd, 1994).Specifically; The looping mill rolling equipment (not shown) that comprises the pair roller (not shown) have increase progressively stretching base (or its part) thereby and make the intermeshing tooth (not shown) of said base (or its part) plastic deformation, thereby give base ductility in the looping mill rolling zone.In one embodiment; Carry out looping mill rolling at least one the part that egative film 26 can be in front waist region 36 or back waist region 38; For example base 100 below back/preceding inside/outside abdominal stretch panels 360,370,380 and 390 and/or be close to the part of said abdominal stretch panels, and other zone can comprise the elastic moulding material fleece of structuring class.

Above-mentioned activation method is to comprise that through use one group of pair roller of the tooth that direction staggers realizes, makes when the material such as base fleece 149 or egative film during through intermeshing roller, makes said material deformation with the required activation pattern of generation in fleece.As other a kind of selection; One of them tooth of said roller can be around (for example can be discontinuous shapings activation at intermittence for the tooth on the successive opposed roller around the roller; Structuring class elastic forming fleece) or the continuous activation of pitchization (for example, but not in the crotch district by activation continuously) in relative lumbar region.The intermeshing degree of depth of tooth (being the depth of engagement) will determine fleece to be increased progressively stretching and/or therefore plastic deformation to what degree also determines to give to fibroreticulate ductility degree.

In some embodiments, base fleece 149 can be activated largely in the part of the side barriers or the hoop wing, for example, and the length of activation/deformed area or the depth of engagement.For example, in these embodiments, one or two in the lumbar region of the base of next-door neighbour's side can comprise the ridge and the paddy of long vertical trend, and other part of lumbar region can comprise the ridge and the paddy of relatively short vertical trend.As other a kind of selection; Can comprise being deformed into in the lumbar region of the base of side and/or end limit direct neighbor one or two forming big (promptly darker) vertically ridge of trend and material of paddy largely, and the ridge and the paddy of vertical trend that other parts of absorbent article can comprise less relatively (promptly more shallow).

In certain embodiments, the activated partial among in the lumbar region can comprise successive activation pattern (for example, through ring-rolling) and activation pattern (that is the elastic moulding material fleece of structuring class) at intermittence before or after being arranged on of base fleece 149.These two kinds of activation pattern can be overlapping or the parallel type relation be provided with.For example; As more particular embodiment; Whole base fleece 149 can carry out the activation at intermittence to form the elastic moulding material fleece of structuring class; And the part that is arranged in the lumbar region one or two of base fleece 149 can be carried out continuous activation, makes region of activation at overlapping intermittence, continuous region of activation.

360 and 380 time with 390 and outside not using encircles roll shape (for example, continuously) activation and can on the outside of

lumbar region

36 and 38, produce ripple 636 in using.Specifically, base 100 (comprising egative film 26, flank 147 and liner 22 (when existing)) can be by the outer surface 104 of rippleization so that fluctuating to be provided, thereby form ripple 636.It is believed that these ripples 636 provide the ductility impression when during the lumbar region of goods is wearing, being stretched.

But carry out looping mill rolling across whole width in one or two of base 100 pro-/

back waist region

36 and 38,, can only carry out looping mill rolling on a part of base 100 width perhaps as other a kind of selection.In another embodiment, but the part of looping mill rolling base 100, and wherein flank 147a and b are overlapping and link in the district 151,152,153 and 154 at flank and to join on the base 100.Can before forming flank 147a and b, carry out ring-rolling in the part of folding base seat 100, after flank 147a and b have formed and/or linked, carry out ring-rolling perhaps as other a kind of selection.In addition, can carry out ring-rolling after being connected at back/preceding inside/outside abdominal stretch panels 360,370,380 and 390.

The preceding transverse center part 117 of base 100 can link the wherein flank 147a of base in the district 151,152,153 and 154 with flank with back transverse center part 118 and the part of the inner surface 102 that 147b can be attached to base has different ductility scopes.In addition or as other a kind of selection, when standing the relative tensile force of given level, the base each several part that

transverse center part

117 and 118 comparable flanks link in the district is extended to greater or lesser degree, can easier or more difficult extension.For example; If base was processed on its whole width, can evenly extend before flank is shaped; Then two layerings in flank links the zone of distinguishing can have the effect that reduces the lateral extensibility under the relative tension of those zones at given level after flank is shaped; The said tension force for example flank of parallel by serving as " spring " produces, and said parallel " spring " can be extended so that the following linking portion of extension base.And for example, can be with the region deformation of the change in the transverse center of the base part to the regional greater or lesser degree that links the change in the district than flank, so that the transverse center part links the easier or more difficult extension of appropriate section in distinguishing than flank.

In addition, shown in Figure 29 and 30, in egative film, side barriers and the hoop wing one or the part of its combination can be activated so that the vertical ductility than levels to be provided as stated.In this type of embodiment, the tooth that at least one the comprised direction in the pair roller staggers makes when meshing with relative roller, in fleece, forms the activation pattern of bending or molding.This bending pattern can be used for the side barriers of activation molding diaper (for example, the diaper of side recess) or is used for carrying out activation on every side at specific diaper element (for example, graphic elements).As other a kind of selection, the pattern orientation that the tooth of roller can not interlock basically, thereby the zones of extensibility of generation longitudinal extension, said zones of extensibility is included in the straight basically pattern that forms in the fleece.The intermeshing degree of depth of tooth (being the depth of engagement) will determine fleece to be increased progressively stretching and/or therefore plastic deformation to what degree also determines to give to fibroreticulate ductility degree.

In some embodiments, base fleece 149 can be activated in the part of the side barriers or the hoop wing.For example, in these embodiments, shown in Figure 29 and 30, can comprise the alternative ridge 712 and paddy 714 of horizontal trend with the base portion of side direct neighbor, and other zones can comprise the alternative ridge 312 and paddy 314 of vertical trend.

In certain embodiments, the activated partial in front waist region or the back waist region of being arranged on of base fleece 149 comprises vertical successive activation pattern (for example, through ring-rolling) and vertical intermittently activation pattern (that is the elastic moulding material fleece of structuring class).These two kinds of activation pattern can be overlapping or the parallel type relation be provided with.

In certain embodiments; The horizontal successive activation pattern that the activated partial of the vicinity of base fleece 149 such as side barriers and/or side setting such as the hoop wing etc. can comprise ridge 712 with horizontal trend and paddy 714 (for example; Through ring-rolling) and activation pattern (that is the elastic moulding material fleece of structuring class) vertically intermittently.These two kinds of activation pattern can be overlapping or the parallel type relation be provided with.In other words, the overlapping orientation of two kinds of different activation types can order be carried out on the same area of diaper.For example; As more particular embodiment; Whole base fleece 149 can carry out vertically intermittently activation in the vertical to form the elastic moulding material fleece of structuring class; And the part of the formation side barriers of base fleece 149 and/or the hoop wing can be made the side barriers and/or the hoop wing on the vertical and horizontal both direction, all be activated by the ridge 712 and paddy 714 of continuous activation to form horizontal trend.

Description to abdominal stretch panels

Shown in each figure; Each abdominal stretch panels all have or vertical proximal of vertical distal side edge of the circumferential extension that is provided with of the corresponding edge of waist of proximate base 100 and vertically relative circumferential extension, the setting of said vertical proximal is compared relatively more near axis of pitch 44 with the setting of vertical distal side edge of same abdominal stretch panels.Each abdominal stretch panels also has side, inner surface and the outer surface of laterally relative longitudinal extension.

Vertical proximal 372 of vertical distal side edge 371 that abdominal stretch panels 370 (when existing) has a circumferential extension in specifically, preceding and vertically relative circumferential extension.Abdominal stretch panels 370 (when existing) also has side 373, inner surface 374 and the outer surface 375 of laterally relative longitudinal extension in preceding.Similarly, when existing, abdominal stretch panels 390 has distal side edge 391, proximal 392, side 393, inner surface 394 and outer surface 395 in the back.Similarly, when existing, preceding outer abdominal stretch panels 360 has distal side edge 361, proximal 362, side 363, inner surface 364 and outer surface 365.Similarly, when existing, the outer abdominal stretch panels 380 in back has distal side edge 381, proximal 382, side 383, inner surface 384 and outer surface 385.

Each abdominal stretch panels shown in Fig. 1, Fig. 2, Fig. 3 and Fig. 6 all has the circumferential scope of the lateral extent that is equal to base 100 basically in corresponding lumbar region.In this type of embodiment, on the position that the wherein front waist region 36 that each abdominal stretch panels all can be attached to base 100 and back waist region 38 link together.For example, if latasuture 115 is to form through any type of pressure bonding or hot adhesion (comprising ultrasonic bonding), then abdominal stretch panels can be attached on the base by same latasuture, makes latasuture run through the thickness of base 100 and abdominal stretch panels effectively.The ability that all layers is bonded together with a latasuture can have the advantage of making simplicity and cost aspect, because this latasuture can form by single adhesive method.

As other a kind of selection, arbitrary abdominal stretch panels all can have the circumferential scope less than the lateral extent of base 100 in certain specific lumbar region.For example, interior abdominal stretch panels 370 and/or 390 only can have approximately the same big lateral extent of distance between the proximal 147 with flank 157.And for example, interior abdominal stretch panels 370 and/or 390 can have greater than the distance between the proximal 157 of flank 147 but less than the lateral extent of the distance between the side 137 of base 100.The each several part of abdominal stretch panels can be interposed between the inner surface 102 of flank 147 and base 100 in this type of of the lateral outer side of the proximal 157 of flank 147.

When diaper 20 was worn, the inner surface of abdominal stretch panels all contacted wearer's skin in each.Therefore, the layer of formation inner surface can be by not stimulating the flexible material of wearer's skin to form.Many suitable materials are known in the art, comprise artificial silk and synthetic nonwoven material, like polypropylene, polyethylene or polyester or other olefinic material of spunbond or carding.

Abdominal stretch panels can have laminar structure.Specifically, abdominal stretch panels can comprise internal layer be arranged on the internal layer outside additional one or more layers.A kind of elasticity pattern in the aforementioned suitable materials can comprise the non-woven material that shows the essence elastic performance, and this material can be used for any layer in these layers.For example, have that abdominal stretch panels 370 is shown among Figure 10 in laminar structure preceding.This abdominal stretch panels both can comprise interior skin contacting adhesive layer 82, also can comprise one or more elastic layers 83 that are laminated on this internal layer 82.The suitable material that is used for elastic layer 83 is known by people in this area, comprises natural rubber strand, synthetic rubber strand, elastomer thin film etc.For elastic layer 83 selected materials can show and the proportional force-responsive of its elongation.Shown in figure 10, abdominal stretch panels also can comprise outer cover 84, and said outer cover is pressed onto on the elastic layer 83 at itself and internal layer 82 facing surfaces upper stratas, thereby forms three layer laminate, and wherein elastic layer 83 is interposed between internal layer 82 and the outer cover 84.

Each of abdominal stretch panels layer can be come lamination through being applicable to the element that is linked to together and any method of their component material.For example, when elastic layer 83 is attached to lax internal layer 82 (and/or lax outer cover 84, if exist) when lasting, can elastic layer 83 be remained on extended state, and it is relaxed.The contraction of gained elastic layer 83 can be tightened up internal layer 82 to produce rugosity mode; The layered product that so forms can extend maximum to internal layer 82 (and/or outer cover 84 on the incipient extension direction; If original dimension existence), wherein only elasticity layer 83 impedances are extended.Similarly the result can obtain through following mode: for example, at first such as internal layer 82 (and/or outer cover 84, if exist) is pleating to tighten up it through making, link the elastic layer 83 that is in relaxed state then.The gained layered product can extend maximum original dimension to internal layer 82 (and/or outer cover 84, if exist) on perpendicular to the direction of pleat crape ridge, and wherein only elasticity layer 83 impedances are extended.

In the certain exemplary method, can both carry out lamination when all lax at elastic layer 83 and internal layer 82 (and/or outer cover 84, if exist).All or part of of gained lamination abdominal stretch panels can be subsequently through following mode " activation ": make it stand to extend in a part of 85a of internal layer 82 (and/or a part of 85c of outer cover 84, if exist), to produce partial fracture or deformed region.In Figure 11; Show tensile abdominal stretch panels with activated partial 85; Wherein the breaking of the breaking of internal layer 82/crushed element 85a and outer cover 84/crushed element 85c is shown in broken lines, and said dotted line is represented exemplary variations, disconnection and/or the separation in the fiber in the non-woven material.The breaking of internal layer 82 in the activated partial 85 of gained layered product/crushed element 85a (and/or the breaking/crushed element 85c of outer cover 84, if exist) only provides minimum or the impedance to the extension on the initial elongation direction is not provided.For example; When non-woven material being used for internal layer 82 (and/or outer cover 84; If exist) time; One or more breaking/crushed element generally includes distortion, fracture and/or the separation of fiber, and it makes said one or more breaking/crushed element can not in the plane of non-woven material, transmit tension force basically.Some suitable activation methods are called as " ring-rolling " method in the art.

If desired, can use the combination of laminating method, as long as these methods are suitable for being linked to together element and their component material.For the abdominal stretch panels embodiment that comprises elastic film and non-woven material, thin film and non-woven material can be all inequality on lateral dimension and longitudinal size.For example, abdominal stretch panels can comprise the layered product of thin film and non-woven material, wherein only partly horizontal expansion on the width of the non-woven material of abdominal stretch panels of thin film.In another embodiment, the thin layer of abdominal stretch panels can be only longitudinal extension on the longitudinal length of the non-woven material of abdominal stretch panels partly.This type of design minimizes the amount of active expanded material, and helps to minimize the overall cost of this structure.

Abdominal stretch panels can have uniform elongation property in its whole zone, or can in different portions, have different elongation properties.For example, can make the part of abdominal stretch panels laterally be extensible to maximum ductility, so that can obtain required stickiness to the wearer greater than the maximum ductility of neighbouring part.Difference on the ductility can for example provide through in activation process, changing local elongation through changing laminating method and/or activation method.

Some user can be expected to tear diaper 20 so that its health from the wearer is removed.For the guidance that can tear wherein about product is provided, can tear on the neighbouring part that position line is printed on abdominal stretch panels and base 100 visible.For example, can with a pair of laterally relative

tear position line
