Description

Absorbent article and manufacture method thereof

The present invention relates to after a kind of usefulness be discardable absorber (for example diaper, incontinence with underwear or underwear) particularly relate to a kind of have can improve absorber and contain the absorber that the invagination of characteristic and fit degree blocks part.

The major function of absorber is to be used for absorbing and holding sepage in the body, prevent that sepage is made dirty in the body so can be used as, get wet medicated clothing or other are as article such as coverlets, usually absorber the situation of easy inefficacy be in the body sepage from the slit flow between absorber and user thigh or the buttocks to adjacent clothes on, reason is that sepage can't suck absorber immediately and absorber is failed and health keeps good fit and produce the slit, make sepage self-priming acceptor bottom surface ooze out, for example, urine easily is deposited on the top layer of absorber in a large number, make urine seepage flow to the slit of diaper bottom, and the diaper bottom also contacts medicated clothing or other article, urine is absorbed by these article, again for example, loose feces is difficult for being absorbed bulk absorption, and easily floats on water sucting surface, and is that passage flows out by the medicated clothing slit at user thigh or buttocks place.

Now, with after can lose the case diaper and comprise a top layer, one backing layer, one middle absorbent core and leg elastic block wing, this block wing generally is to be made of an elastic component, and be wrapped in the continuous part of top layer and backing layer, and then can beyond the edge of absorbent cores, stretch, this elasticity block wing proof can effectively prevent to carry the diaper generation capillarity of full liquid and overflow to and the medicated clothing of diaper EDGE CONTACT on, because this leg elastic block wing is at the diaper edge and a kind of waterproof barrier of formation between the clothes that contacts, and can around the user shank, produce the packing effect, keep sealing to reduce the gap around making shank, but, partly still can seepage along the diaper girth, along with the lengthening of dressing the diaper time, easily bearing strength on the diaper makes between diaper and the health no longer and fits as beginning, the situation of this fit degree variation just causes the shank of diaper and the buttocks place presses sunken and the big space of generation, therefore, when liquid deposition is on top layer, some liquid that directly do not suck just flow to the diaper edge, and infiltration or flow out from here, so contacted clothes or underwear and be absorbed or infiltrate by capillarity from the space of diaper.

Therefore, the diaper that can lose case after this usefulness can be provided with the portion (barriercuff) of blocking near the leg opening place, its function is to stop the clothes of making dirty such as loose feces or a large amount of urines, this blocking can retrain the free-flow of above material and constitute a kind of structure of holding this class material, therefore, when above material free floating or when mobile, it still is included in the diaper on the diaper top layer, similarly case has:

1, the Japan Patent 61-304437 of certain company's application of Japan, February 20 1986 applying date.At Taiwan application case numbers 78218109, patent name: disposable urine trousers.

2, precious alkali (the The procter ﹠amp of company of the U.S.; Gamble company) is called absorber (Absonbant articlehaving unitary waistcap and waistland) in December in 1988 21 days in No. 287944, the United States Patent (USP) of U. S. application (at Taiwan application case numbers 80203819) name with single waist lid and waistband.

In the above-mentioned application case, do not improve because diaper is kept the textural of (fit) that continue to fit at user, liquid still can ooze out the portion of blocking and the clothes of making dirty.And this portion of blocking body contact and do not reach good initial applying effect correctly not, so the common poor effect of applying that continues.

So, a kind of absorber appearance that invagination blocks portion that has is just arranged, for example:

3, the precious alkali of U.S. company in December in 1988 2 days in No. 238045 of U. S. application (Taiwan application case number 80203817), title: have the absorber (Absorbant article having inflected barrier cuffs) that invagination blocks portion.

4,18 days July nineteen ninety of the precious alkali of U.S. company is in 382157 (Taiwan application case number 82213546) title of U. S. application: the absorbent article (Detachabletwo piece obsorbent garment) that can be divided into two lamellar bodies.

Though the and arranged on left and right sides of the absorber in above-mentioned two application cases has the tabs that invagination blocks, but the tabs before absorber is that involution is on top layer, the double-folded sheet at rear portion then is to flip to the outside after 180 ° at tabs, amount to again on top layer, therefore, the double-folded sheet in absorber the place ahead is to be the close state of envelope, and the rear then is to be opened state.When wearing, the tabs of the place ahead sealing is to be positioned at the user front portion, the open tabs in rear then is a fan-shaped buttocks that is positioned at user, the design of this double-folded sheet is when user is stood or be seated, sepage and prevent that it from surveying to two of absorber and overflow in can barrier bodies, but when user at nighttime sleep or when lying low (crouching), this absorber latter half of is to be positioned at the bottom surface of user and to be the level of state, therefore, the open tabs at absorber rear, can't effectively intercept the outflow of body fluid, even body fluid can flow out in the slit by the absorber trailing edge, because the trailing edge of absorber there is no any barrier (or sheet), so can't stop or hold the outflow of body fluid, in addition, two cases must be used more material on making, and remaining angle material (being the material remaining part that can not utilize again after using) certainly will cause the unnecessary burden of maker, and for example: cost increases, storeroom is put and is deposited, problems such as recovery.

In addition, one patent case is arranged, its structure, function and occupation mode are all with the aforementioned the 3rd, 4 cases, (both sides that are bridge shape material fabric (Bridge matcial) are provided with elastic ear portion (Eleaticized ear portions) respectively but at waistband, make the effect of waistband energy tool elastic telescopic by elastic ear portion, but, still unresolved aforesaid problem, this case application people is U.S. Kimberly-Clark limited company (Kimberly-Clark Eorporation) on August 3rd, 1994 in No. 08/286.086, U. S. application (Taiwan application case number No. 84107671) title: the technology of combined elastic ear (Aprocess for assembling elasticized ear portions).

The purpose of this invention is to provide a kind of absorbent article and manufacture method thereof, this absorbent article can prevent effectively that body fluid from oozing out and hold liquid, and manufacture method is easy, and no leftover pieces are saved raw material.

For achieving the above object, the present invention is by the following technical solutions: absorb object and comprise: absorber, waistband, described absorber comprises: permeable top layer, waterproof backing layer, absorbent cores between top layer and backing layer, be positioned at the tabs that blocks on vertical edge side, absorbent cores both sides, respectively block tabs one center rim and a terminal edge are arranged, the edge place is gripped with at least one flexible member endways, absorber is divided into first waist, second waist and be positioned at first waist and the crotch of second waist, two free end auricles of described waistband have the paster fixture, portion with a tight waist fixes with the top layer of absorber second waist, waistband and be positioned at the absorber second waist place and fix to the lamellar body of absorbent cores invagination.

Advantage of the present invention: because absorber rear end and waistband is bonding and the both sides tabs of absorber second half section, make absorber form the portion of blocking of one or three drip-preventing functions, and, absorber leading portion both sides tabs has makes widely known function laterally, the more docile user of absorber front portion, therefore, can prevent effectively that all body fluid from oozing out and hold liquid no matter user is to stand or lie low.Entire product is integrally manufactured, and easy, no leftover pieces are increased economic efficiency.

Figure 41: waistband axonometric chart (fold type)

Fig. 1, shown in diaper 10 be to shrink elastic components at all to draw and present the not contraction state that shakeouts after removing, wherein some part is cut open so that clearly illustrate its structure.Diaper 10 can be divided into first waist 11, second waist 12 and a crotch 13 among the figure, and in addition, diaper 10 has a horizontal centrage 15 and a vertical centrage 16.

Diaper 10 comprises a water penetration top layer 21, and liquid collecting face 20 is just defined by top layer 21; Other has a waterproof backing layer 22; One middle absorbent core 30 can be divided into front waist edge 31, both side edges 32, back waist edge 33; One waistband 40 is to be used for diaper 10 is fastened on the health waist; About two tabs 60 are lamellar bodies of opisthotonos again after stretching out by flank 50 both sides, an its broken line edge 61, one terminal edge 62 of having got everything ready, as dividing, then be divided into open front end portion 63, the rearward end 64 of opisthotonos and the turning point 65 between leading section and rearward end 64 with section; One elastic component is in order to terminal edge 62 of tabs and liquid collecting face 20 are separated, and produces the fold of an elastic shrinkage; One involution spare 81 (as: viscose glue, the oblique line district of reporting to the leadship after accomplishing a task shown in Figure 2 is an adhesive area) can be fixed giving involution between diaper 10 rear ends and the waistband 40.

The length of the backing layer 22 of diaper 10 shown in Figure 1 and width be all greater than absorbent cores 30, and the edge that is extended beyond will constitute the periphery 50 of diaper, i.e. the outside of diaper.21 of top layers are identical with backing layer 22 areas, and common driving fit becomes periphery.

First waist 11 of this diaper 10 is the Attacking Midfielders that are centered around user, and second waist 12 then is the low back that is centered around user, but the length of second waist is length than first waist.This second waist is a waistband 40, two side ends at it respectively has a paster fixture 41, when first and second waist is centered around the forward and backward waist of user, the both sides free end of this waistband 40 can be topped on the diaper surface of first waistline 11, and it is bonding by paster fixture 41, and make first and second waist combination, and then the whole cladding of the waistline of user is got up.Cause in crotch 13, its part of occupying diaper is the zone that encases the user waist after putting on, and 13 of crotch are the zone between first waist 11 and second waist 12 on the diaper, and comprises the position of putting on behind the diaper between thigh and encasing lower body.

Secondly, first waist 11 shown in Figure 1 is waists of a common pattern, if first waist is increased, and become first waist, 14 (see figure 3)s of lengthening, then can become one " high waist absorber ", be in after the absorber lengthening about " high waist absorber " is different with general absorber, its portion with a tight waist can be positioned on the user hipbone, surpass waist border umbilicus, what be convenient to belt like this is to tie up, prevent from after urine wets or drains, to increase the weight of to cause absorber sagging because of excremental, but, above-mentioned " high waist absorber " only is implemented in the absorber aspect of adult's usefulness, for example: the application case in Taiwan numbers 84110667, title: " have the suspension that prevents sagging and waist support function with after be the disposable type diaper; U. S. application case 08/595329, however further implement for diaper (particularly this have the diaper that invagination blocks portion).Because the growth of first waist, the related front waist edge that also makes absorbent cores 30 31 be and then lengthening also, so become the Attacking Midfielder 31 of lengthening '.

Among Fig. 4, the absorbent cores 30 of diaper 10 be bring to Front 21 and backing layer 22 between, and the flank that to be top layers 21 in the absorbent cores both sides extend beyond mutually with backing layer 22, promptly the periphery 50, and the A-A sectional drawing is that the leading section 63 that is positioned at tabs 60 is the part that the plane is opened wide, and is to come sealing-in fixed with PUR or in the mode of spray glue, hot pressing wheel between top layer and the backing layer.

In addition, between the top layer 21 of periphery 50 proximal end edge 62 and backing layer 22, be provided with flexible member 66, flexible member best one or more, among the figure be three, this flexible member can be thin elastic cord.Elastic component must be at top layer 21 and backing layer 22 before the sealing-in, promptly be placed between the two-layer body earlier, and at top layer and backing layer mutually after the sealing-in, can use the terminal edge 62 of periphery 50 to produce a fold edge that shrinks, this fold edge can be in crotch, and allow user have after the dress outside the comfortable sensation, the more important thing is that it can be isolated by means of the elasticity set effect of flexible member and with liquid collecting face 20.

As can be seen from Figure 5, the absorbent cores 30 of diaper 10 is the parts that are minimum width between both side edges 32, therefore just the periphery of more forward and backward absorbent cores 31,33 is big for the periphery 50 of absorbent cores both side edges 32, has only herein periphery 50 to have wing Qu Zuoyong slightly on launching, especially antermarginal part.

Among Fig. 6, this absorbent cores belongs to folded structure in the back, so liquid can't be oozed out with capillarity by the root of tabs 60 in the body, also is unlikely by terminal edge 62 simultaneously and overflows.

Among Fig. 7, the formed tabs 60 of 30 liang of side peripheries of absorbent cores, the conduit 67 that between broken line edge 61 and terminal edge 62, can become to block, this groove is sealing, and as stopping, hold and holding interior liquid sepage and use, till taking off diaper 10, the tabs 60 in aforementioned is by a turnover mechanism periphery 50 to be given giving extrusion forming again after 90 ° of turnovers, and has a broken line edge 61 formation at the position of tabs turnover.

Fig. 8 demonstrates the section structure between diaper 10 and the waistband 40, and wherein the formed tabs 60 of 30 liang of side peripheries of absorbent cores is nearly 90 ° towards the absorbent cores inner bending, and is sealed engagement between tabs 60 and waistband 40.

Among Fig. 9, between diaper 10 and the waistband 40 and the section structure of paster fixture 41, among the figure as can be seen the formed tabs 60 of 30 liang of side peripheries of absorbent cores be to be 90 ° towards the absorbent cores inner bending, and be sealed engagement tabs 60 and 40 with a tight waist, and the top layer of diaper 10 also is sealed engagement with waistband 40.

Therefore, the rear end of diaper 10 combines with waistband 40, and be closed, and add the rearward end 64 of diaper 10 dual-side tabs again, block the limit thereby become three of diaper rear portion, form the leak proof region of a U-shaped, in addition, the anterior and last sealing-in of diaper 10 and waistband 40 is so form a sealing-in district 42 not, and the part of sealing-in is only in the rear portion sealing-in (see figure 2) of diaper 10 with waistband 40, so form sealing-in district, a back 43; In addition, also be sealing-in between diaper both sides, 10 rear end and the waistband 40, form a side seal and meet district 44, use sealing-in district 42 to produce the pocket 45 of a U-shaped, this pocket can make the front portion of waistband 40 form one to stop bag, stopping, to hold and to hold sepage in the body, when particularly user lies low, this pocket can effectively be brought into play barrier functionality, and this function is that original diaper is unexistent.

Above-mentioned tabs 60 also can combine with the periphery of diaper so that independently member is next, Figure 10 for example, this figure is equivalent to D-D ' sectional drawing of Fig. 1, tabs 60 is by an involution spare 69 (PUR for example among the figure, bonding pearl, spray glue etc.) the terminal edge of base and periphery 50 is joined and become an involution portion 68, above-mentioned Fig. 7, in the example shown in 10 liang of figure, its broken line edge 61 or involution portion 68 are the structure of an involution, it has barrier liquid through capillarity and among the function Figure 11 by the portion of blocking, front waist edge 31 left and right sides of absorbent cores 30 have the lug 34 that arc protrudes, because the protrusion of this lug, so it is all littler than other position by the peripheral width between terminal edge 62 to 34 apical margins, the structure of this structure energy reinforcement diaper 10 front end both sides, the position in corner particularly, and make the front end structure on two sides of diaper 10 become more strong stiffened edge 52, and can not present soft, in addition, after the user dress, these lug 34 peripheral extent can be born bigger side direction pulling force, be more suitable in the stickup of paster fixture 41, and can not cause torsional deformation after pasting.

In addition, adding in the microscler absorber shown in the earlier figures 3, its absorbent cores 30 ' length also longer, especially front waist edge 31 ' length longer than the diaper absorber of GENERAL TYPE, but two of front ends at diaper still are provided with lug 34 ' structure, in order to strengthen the intensity in corner, diaper front end both sides, prevent from after sticking paster fixture 40, to cause the product distortion.

Among Figure 12, the front end both sides of absorbent cores 30 also are provided with the structure of lug 34, so the front end both sides of diaper seem softer in the use, structural stress also a little less than, this is the shortcoming of general traditional type absorbent cores and diaper.

Among Figure 13, the rear end sealing-in of the back end periphery of diaper 10 51 and waistband 40, this sealing-in can be by modes such as the heat-sealing of PUR, spray glue or hot pressing wheel and involution, the zone of this involution promptly: the position in sealing-in district, back 43.And do not have involution between the front portion of waistband 40 and the diaper 10, and this zone promptly is not involution district 42, the place ahead, owing to this involution district, end forms a pocket 45, makes the front portion of waistband 40 become a structure that stops.

The waistband 40 that is disclosed among this figure is one to have the waistband that opisthotonos becomes double-deck lamellar body, its structure can be divided into outer-skin sheet 46, inner layer piece 47, inner layer piece 47 is to belong to integrated lamellar body with outer-skin sheet 46, but inner layer piece 47 is after invagination, it holds 471 to be the top layers that are fitted in diaper 10 to the greatest extent, and the other end 472 is an opening; The rear end of outer-skin sheet 46 is to fit with the top layer of diaper 10, but then not bonding with the top layer of diaper 10 in the part that inner layer piece 47 is arranged.

Among Figure 14, waistband 40 is lamellar bodies of a monolayer, and it is that back involution district 43 by outer-skin sheet 48 engages with diaper 10, and the place ahead then is involution district 42 not, not with diaper 10 involutions.

Among Figure 15, tabs 60 be one by outward towards the lamellar body of 90 ° of inner bendings, and be divided into upper and lower tabs 601,602; Under tabs 60 limits is diaper periphery 50, tabs then is a lamellar body that further extended again by peripheral 50 sides and bending, between tabs 60 and waistband 40 is sealed engagement, and also be sealed engagement between waistband 40 and the rear perimeter edge 51, in addition, go up half that 601 of tabs account for down tabs length among the figure.

Among Figure 16, tabs 60 can be divided on one synusia 601 and following synusia 602, can sealing-in or not sealing-in between the upper and lower two-layer tabs, and last synusia 601 width are identical with the width of following synusia 602.

Among Figure 17,60 is a monolayer lamellar body, the upper surface of tabs and waistband 40 sealing-ins, but the inner face sealing-in or the not sealing-in of tabs.

Figure 18, tabs 60 are independent lamellar bodies, and are a pair of synusia, the last synusia of this tabs 603 surfaces and waistband 40 sealing-ins, 604 bottom surfaces then with rear perimeter edge 51 sealing-in or not sealing-ins.This width of going up synusia 603 is half of following synusia 604; Also can be isometric, for example shown in Figure 19.

Among Figure 20, tabs is independent lamellar body, and is fixed on involution spare 69 on the periphery 50 of diaper, and secondly, this tabs is the monolayer lamellar body, the upper surface of tabs and waistband 40 sealing-ins, but and the inner face sealing-in or the not sealing-in of tabs.

Figure 21 surface goes out the section that diaper 10 front end right corner fall, also express simultaneously the section of the lug 34 of absorbent cores, wherein lug 34 sides are still by the periphery that be combined into 50 of last top layer 21 with following backing layer 22, and insert and put flexible member 66 in the inside at proximal end edge 62 places, make the leading section 63 of lug near zone form a stiffened edge 52, to strengthen the structure of diaper front end.

Among Figure 22, waistband 40 is belt bodies of an elongated rectangular shape, two side ends adds puts a paster fixture 41, this paster fixture is one to tear the fixture that can be affixed on diaper front end both sides after getting the top layer, in addition, also has Figure 23, moulding shown in Figure 24, among Figure 23, there is the chimb 402 of protrusion in root edge limit 401 central authorities of waistband 40, there has been chimb that not sealing-in district 42 areas between waistband and the diaper are strengthened, among Figure 24, waistband root edge limit 401 also has the rib 403 towards inner bending, this rib not with waistband body 40 involutions, and be unsettled turnover lamellar body, this lamellar body can be used as one and stops lamellar body, to prevent that sepage flows out again in the body forward after pocket 45, so have the function that deters.

Among Figure 25, tabs 60 is identical with aforementioned tabs shown in Figure 17, among Figure 26, tabs 60 is identical with aforementioned double-folded sheet shown in Figure 15, the tabs 60 of Figure 27 is identical with tabs shown in Figure 16, three kinds of tabs that Figure 25,26,27 shows or aforesaid Figure 18,19,20 tabs moulding, the scope of its tabs 60 is by vertically all being that front end by diaper extends to ending of rear end, its laterally be by broken line edge 61 (or sealed portion 68) till the terminal edge 62, but tabs its leading section 63 in use all must be open state, and rearward end 64 is the turnover shape.

Among Figure 28, waistband 40 can extend horizontally to first waist 11 of diaper, and be attached to the corner of the first waist both sides and reach joint by the paster fixture 41 of two ends, 64 of rearward end as for tabs 60 are in the rear end of diaper 10 and towards invagination, the rearward end tabs 64 of this invagination forms one and prevents the function that side is oozed, and waistband 40 promptly becomes the device that leak an anti-back with diaper rear perimeter edge 51 involution places because the leak-proof device on aforementioned three limits, so that the rear portion of diaper becomes a liquid collecting zone 20.In addition, the tabs 60 of diaper crotch 13, some belongs to preceding tabs 63, another part belongs to back tabs 64, the existence of the terminal edge 62 of the tabs of crotch because of having elastic component so can arch upward and produce fold, makes owing to arching upward between the thigh, buttocks of crotch and user and just can not produce the seepage phenomenon, and the limit of fold is except that tool tightens function, also not can and thigh, buttocks between produce too big friction.

Among Figure 29, user is a child, except that the child, also can extend to adult (for example adult of incontinence), when diaper 10 of the present invention is worn in child's buttocks, the forward and backward end 63,64 of tabs can be close between child's the thigh, buttocks and strand ditch, and by the constraint of waistband, and make diaper firm.If this diaper is to belong to a kind of king-size diaper, as Figure 30, so whole waistband 40 is to be positioned on the hipbone 70, and by the retaining that pulls of hipbone, can make waistband supported, so be that solid effect is good than the diaper of the former (shown in Figure 29), the most suitable adult of this extended type diaper uses, because lifting rate is more in adult's the body, the suffered load of diaper is also bigger, and under the situation that load increases the weight of, as there is not king-size diaper to implement then to be easy to produce sagging.

See it being the latter half of diaper 10 among Figure 31, and the section of absorbent cores 30 is the positions at two arc lateral margins 32, produce the flanging 60 of an invagination at two side peripheries 50 of absorbent cores, this flanging can form a function that prevents side leakage, the position that easily leaks outside commonly used is the moderate place of the position (position of the horizontal centrage 15 shown in the 1st figure) of kinking between tabs 60 leading sections 63 and rear end 64 to preceding tabs 63, this position is first crotch 17, in the present invention because terminal edge 62 inside of preceding tabs 63 have flexible member, so the constrictive force that tabs produces after the fold will clad between the lower body and both sides thigh ditch of user, and then effectively prevent from down to leak.

Among Figure 32 since the manufacture process of diaper (being absorbent cores 30, top layer 21, backing layer 22) with common identical, and the packaging process of diaper is also identical, so will omit the manufacture process and the packaging process of diaper in the following explanation, combining between waistband and waistband and the diaper, manufacture process only are discussed, and its process is divided into the following step.

With adhesive-bonded fabric or elastic non-woven cloth is waistband substance 1,2, paste sticky cloth, 3 in waistband substance both sides, above-mentioned adhesive plaster is inwardly given a discount, 4, adhesive plaster is through the pinch roller pressing, and become a paster fixture, 5, spray glue or gluing on the waistband main body, 6, with slitter wheel the waistband main body is equidistantly cut off, and form required waistband, 7, by air-breathing take turns with aforementioned waistband band from, 8, the diaper that the waistband and the other end transported is fitted, and the diaper of sending here has combined middle absorbent core, 9 in advance, with waistband both sides auricle invagination, 10, auricle is with pinch roller pressurization leveling, 11, diaper is equidistantly cut off molding, 12, finished product is delivered on the packer, pack.

Among Figure 33, the waistband substance 400 of adhesive-bonded fabric or elastic non-woven cloth advances with horizontal direction, other has two film original tapes 410 under the equidistant cut-out of one group of cutting knife wheels 80, and form scutellate paster fixture 41, and through small-sized air-breathing take turns 82 pass on after, and be affixed on the two side ends of waistband substance 400, but only some combines with waistband substance 400 film, another part is then by means of the turnover of leading flap 83, and on the anti-surface that is affixed on film, and through the spreading of pinch roller 84, making after the film doubling can mutual fitting together, and then becomes a paster fixture.

Aforesaid waistband substance 400 after the gluing operation of a force feed and a glue sprayer 85, equidistantly cuts off waistband substance 400 with slitter wheel 86 more again, and then forms required waistband 40.

This waistband 40 is taken turns 87 it is taken away by air-breathing again, because air-breathing the wheel has air-breathing function, inhale solid being passed on again afterwards so can will girdle the waist, waistband 40 can fit with the diaper substance 100 that the other end is sent here, these diaper substance 100 inside have possessed the middle absorbent core, after waistband 40 and diaper substance 100 are bonding, simultaneously by air-breathing take turns 87 with the extruding of rolling wheel 88, and close and firm is together.

Secondly, aforementioned diaper is again through a folding of leading of leading flap 89, can be with the auricle 40 of waistband 40 both sides ' give invagination, make auricle be unlikely the side of protrusion at diaper substance 100, the diaper substance is again through the equidistant cut-out of all knife wheel set 90 in addition, and become the structure absorbent article of a molding, and again finished product is delivered on the packer at last, carry out package handling.

The colloid area that glue sprayer 85 among Figure 33 is sprayed on waistband is to be a U font, so waistband can make three edge sealing of a pocket-shape with after diaper combines.

Among Figure 34, diaper substance 100 with before waistband 40 combines is not being operated through a spray glue, cut-out and spreading.Diaper substance 100 is after the spray glue of a glue sprayer 91, leading flap 92 through one again transfers tabs, make tabs be affixed to diaper substance 100 surfaces, then after the spreading of one group of rolling wheel 93, being delivered to air-breathing 87 lower edges of taking turns again combines with waistband 40, after if the diaper substance is implemented via the mode shown in this figure, then with will not have any slit after waistband combines, as implementing without the mode shown in this figure, mode promptly shown in Figure 33, then the tabs of diaper is after turnover, still remaining gapped between tabs and the diaper top layer, though this gap can influence the drip-preventing function of diaper rear end in theory, does not have very big influence on the implementation.

Manufacture process shown in Figure 34 can be represented with Figure 35, when A (diaper substance) after B (gluing), C1 (tabs turnover), D (extrusion forming), waistband with aforementioned the 8th step combines again, and like this, the situation that never has leakage between diaper that manufacturing is come out and the waistband takes place.

In addition, diaper also can be implemented with other method, its process for when A (diaper substance) behind B (gluing), again through C2 (subsides double-folded sheet), D (extrusion forming), and then combine with the waistband of aforementioned the 8th step.This embodiment is represented by Figure 36, among the figure, diaper substance 100 vertically is interrupted gluing through glue sprayer 91 earlier, after the 95 laterally uninterrupted gluings of two glue sprayers, again left and right two tabs 60 are fitted on the diaper through pinch roller 94, and then after the rolling of one group of rolling wheel 93 was closed, the waistband with aforementioned the 8th step combined again.This programme and Figure 34 difference are that tabs 60 is independent lamellar bodies, are fixed on the diaper after pasting.

Among Figure 37, bilateral tabs 60 all is closed form, has only when in use, just the leading section 63 of tabs can be opened wide, and rearward end 64 is closed, and then wears to carry and use.

Among Figure 38, the length of waistband 40 is L1, can combine with the diaper 10 of lower end after taking turns 87 pass on through air-breathing, at this moment waistband length still is L1, so still as hereinbefore, produced by this way waistband 40, it presents an even curface at diaper 10 and waistband 40 bonded positions, promptly as shown in figure 40.

Among Figure 39, originally be of the expansion of the waistband 40 of L1 length through its side direction pulling force, and make length become L2, at this moment as combining with diaper 10 again, then can produce a contraction and become the fold attitude between waistband after the combination and diaper, i.e. elasticity fold part 49 as shown in figure 41 is no matter it can allow the size of its waistline of user be suitable for, and be not subject to certain size range, and be that solid effect is also better.
