TITLE:

ABSORBENT ARTICLE FOR USE IN THONG UNEDERWEAR

TECHNICAL FIELD:

The invention relates to an absorbent article whi ch is designed to be worn together with thong underwear.

Current fashion, with tight-fitting, figure-hugging clothes, has meant that it has become more common to wear so-called ttongs, which have a very narrow crotch area.

As the wearing of thongs has increased, so theres has also been a greater .need for an absorbent article, such as a sanita ry towel, an incontinence gorotector or a panty liner, adapted to these types off briefs. «Conventional absorbent articles generally have as rectangular or hourglass shape. However, a rectangular or hourglass-shap ed article juts out beyond fhe edges of the thong and takes away some of ghe elegance which is the : 3ctual purpose of wearing this type of underwear. Alternatively, the article bas to be made narrow enough for the whole width of the article to be 2 accommodated within the edges of the narrowest part of the thong. It nas een proposed to design the absorbent articles with a shape matching thong winderwear. See SE 9803981-1 and WO 97/39713, for example. SE 9803981 cdescribes an absorbent article which is character-ized by the fact that the wvvidth of the rear end portion of the article is at naost 40 mm and the long ssides of this end portion are essentially curved. _Although such an article faunctions satisfactorily in terms of discretion, it has proven difficult to get the article to fit securely in place in the thong during use=.

Thus, one of the most important problems to be so lved in absorbent articles for these types of briefs is the fastening to the briefss, since the crotch area of the thong is very small. It is also important, for several reasons, for the article r ' to fit exactly correzctly in the thong. On the one hand, incorrect positioning of the article means. that the discretion and user comfort suffers, and, on the other hand, it is Of the greatest importance that the article, on account of its small surface are a, should be placed in such a way that it is able te take up and absorb all the body fluids eliminated. Secure and correct fasten ing of the article is therefore also important from the point of view of leakage.

US Des. 394,503 discloses an article with a shape which is intended to fit in thong underwear and which is additionally provided with protruding side tabs.

The tabs in this rmodel have a rectangular shape with sharp edges. An article with flaps of this kind will cause discomfort because the sharp edges of the tabs will chafe or cut into the wearer during use.

US 5,713,886 dlescribes panty liners intended to be worn in thongs and provided with fastening tabs. The fastening tabs are located both en the first end portion, whi ch is the wider portion of the article, and also on t he second end portion, whi ch is the narrower partion of the article. The disad ‘vantage of an article accorcding to this patent is that there are a large number of tabs for the wearer to fassten to the briefs and that two of these tabs are pla ced on the : first end portion of the article, which reduces the adaptability to different shapes and sizzes of thong. A further disadvantage of an article from US . 5,713,886 is that the tabs of the wider end portion will be visible uring use, which takes away from the advantage of wearing thongs.

BRIEF DESCREPTION OF THE INVENTION:

An article of thie type discussed in the introduction, in which th e problems associated with previously known articles of this kind are essentially eliminated, is characterized, according to the invention, by the fact that at least the secord, rear, end portion has flexible fastening tabs for fastening of the article in thee thong.

According to a preeferred embodiment, the fastening tabs have an essent.ially rounded contour. According to further embodiments, the fastening tabs are provided with fas tening means in the form of fastening adhesive or seme type of mechanical fastening arrangement, for example hook-and-Boop fasteners, snap fasteners, friction-type fasteners or the like. It is also possible to use combinations of mechanical and adhesive fastening membwers.

According to one embodiment, the fastening tabs are secured against each other. According to a further preferred embodiment, the fastening ®abs comprise a soft material, such as a nonwoven, foamed plastic, or the like.

To allow the article to be secured by the front edge to the briefs too, the front end portion is adwantageously provided with a fastening arrangement. Such a fastening arrangement can comprise fastening adhesive or a mecharmical fastening arrangement, for example, a friction coating, hook-and- loop : 15 materials, grippimg members, snap fasteners or the like. The faste ning arrangement on the front portion of the article can have a special shape=, for example oval, rectangular, lines or the like. ' To facilitate correct positioning of an article of the type discussed in the introduction, the article, in a preferred embodiment, can have a raised : portion. By this means, it is also possible to achieve an increased absorption capacity of the article and increased security against leakage. According to a further preferred embodiment, the article has inwardly curved side edges, in order to better folJow the shape of the leg edges of the thong.

According to one embodiment, the width of the rear end portion is 15 to 40 mm and preferably 18 to 30 mm. To fit well into thongs, the length of the article is advantageously 150 mm or less.

Liquid barriers ca n also be arranged between the absorbent part of the article and the fastenin g tabs. Such liquid barriers can consist, for example, of liquid-blocking welds, compressions, liquid-repelling material such as wwvax,

plastic or the like. It is also possible for the fastening tabs to be made of a . . hydrophobic material such as a hydrophobic nonvwvoven, plastic or the like.

According to one embodiment of the invention, tree fastening tabs are formed $5 from separate pieces of material wherein each fastening tab exhibits an edge portion which substantially coincides with a corresponding edge portion on : the long side and wherein the fastening tabs and the edge portions are attached to each other within the coinciding edges portions with the fastening tabs being oriented towards each other with the non-attached edge portions extending in over the absorption body on the urderside, i.e. the side of the article which, during use, is intended to be facing away from the user.

According to one embodiment of the invention, the rear end portion is provides with a fastening arrangement for fasteni ng in the thong.

DESCRIPTION OF THE INVENTION:

According the invention, the above problems are solved by the fact that the absorbent article is constructed with its rear p ortion so arranged that the ’ article is not visible from outside when placed in £hong underwear, and that at least this portion is provided with fastening tabs. :

It is advantageous for the absorbent article to fol low the edge of the briefs so that the available absorption surface is as great as possible. An article which is as wide as possible is also important from the point of view of leakage. The risk of side leakage from the briefs and also of staining of these briefs is minimized when the article is adapted to the shape of the briefs. The absorbent article according to the invention thesrefore has long sides which follow the contours of the briefs in the crotch area. An article which closely follows the shape of the briefs will also be very well concealed during use.

Lt . WO 00/72790 PCT/SE00/00948

It is very important that an article having a smaller absorption ssurface than a conventional abssorbent article, which is the case of an articlee according to the present inve ntion, fits correctly and securely in place in th-e briefs, since an article which has such a small absorption surface and whici moves in the

S briefs is of no use from the point of view of leakage. According to the invention, the fa=stening of the article is ensured by means of the fact that the article has long ssides which follow the contour of the briefs in tlhe crotch area and which are provided with fastening tabs.

In a preferred embodiment of the invention, the fastening tabs have a rounded contounr in order to avoid the chafing and discomfort to the wearer which can be =caused by fastening tabs which angled edges. It is also possible to furth er enhance the comfort of the article by making the fastening tabs from a soft_, comfortable material such as a nonwoven, a f oamed plastic, or the like. To hmold the absorbent article in place in the thong, it is important for the fastening tabs to be secured either to each other or to the thong. This is best done bw providing the fastening tabs with some forrm of fastening : arrangement, for example adhesive, hook-and-loop, snap fasteners, friction- : type fasteners, er the like. . To provide max_imum protection against leakage, it is preferabmie that the first end portion of the article can also be secured correctly in the briefs. To give the user as wid e a choice as possible as regards positioning =f the article in the briefs, a fas tening means comprising fastening adhesive o r a mechanical fastening arrangyement are preferred. This gives the user an article which is easy to secures in the briefs and which can also be move«d by a simple manoeuvre, if one feels the first positioning was not comreact. To further simplify matterss for the user, this fastening arrangement ca n also have a special shape so that the user can, for example, avoid having fastening adhesive across the entire reverse side of the product.

] Many tests have shown that, in order to reduces leakage when using an . absorbent article, it is useful for the article to come into contact with the liquid : as rmear as possible to the body. A preferred way of doing this is to provide the article with a raised portion. This also increases the absorption capacity.

The raised portion additionally acts as a positioning member.

It haas surprisingly been found that the crotch width of the majority of thongs is - more or less identical. Measurements have also shown that a width of absorbent article not exceeding 40 mm is in most cases sufficiently narrow to be concealed by the thong.

The width is preferably 15 to 40 mm.

It haas been found that it is not necessary for the whole article to be of a : 15 defimed, very narrow width, since the front part of rmost thongs on the market is saufficiently wide to permit use of an article of normal width with more or lesss any contour on the long sides. This means t hat that part of the article which is placed towards the front on the user cane be structured more freely dep ending on the requirements in respect of absor gtion capacity.

Corsequently only the end portion intended to be placed rearwards on the . use r and fit in the narrow part of the thong has to be structured with a maximum width and a special contour of the longs sides. This portion of the arlicle will in the following be described as the rear, or the second end portion. The part of the article which can be structuured more freely is referred to hmereinafter as the front or the first end portion. T” he two end portions do not necessarily divide the article into two equal parts im the longitudinal direction.

The= first end portion is preferably 60 to 170 mm long and the second end portion is preferably 30 to 90 mm long. The entire length of the article is cormsequently 90 to 260 mm.

Le : WO 00/72790 PCT/SE00/00948

In order to reduce the risk of side leakage, it is advantageous if no direct connection exists between the cover or the atosorption body of the article and the fastening tabs. By arranging fastening tabs in the form of separate, discrete pieces of material on the article, thes join between the tabs and the

S rest of the article will form a kind of leakage barrier, whereby all fluid transport paths to the fastening tabs will be cut off. Moreover, when the fastening tabs consist of separate pieces of material, the composition and other properties can be chosen freely, independently of the materials forming the cover of the article. Furthermore, it is possible to produce the articles with negligible material waste when the articles are cut out. Due to the fact that the fastening tabs are formed from separate pieces of material which are arranged and attached to the long sides of the article in a manner with the fastening tabs extending towards each other in over the underside of the article, i.e. on the side of the article which during use is intended to be facing : 15 away from the user, it is possible to provide an article wherein the fastening tabs, in their initial configuration, are not directed outwardly from the article. g This implies that the articles are easy to package since the tabs do not require the provision of a special folding step.

A further advantage by attaching the separat e pieces of material or the tabs . on the side of the article which during use is i ntended to be facing away from the user is that the common edge portions of the article and the side tabs can be shaped to fit the curved leg edges of the thong. This implies that the tabs will not wrinkle or deform in other ways as a result of the fastening in the thong something which usually happens with side tabs which are folded around the edges of a pair of briefs. Further, when such an article is arranged in the thong, the leg edges of the thong are guided in between the tabs and the cover material on the underside of the a rticle, i.e. the side of the article which faces away from the user. During use, the article is curved in the longitudinal direction in order to conform to the body of the user. Thereby, tensional forces are created in the tabs, cau sing these to press against the cover material on the underside of the article and clasping the leg edges of

B the thong between the tabs and the remaining parts of the article. In order to obtain maximum such “self locking”, it is advantageous if the fastening tates exhibit a certain rigiclity, i.e. are more rigid than each of the covering layers - and, preferably, that the rigidity of the fastening tabs exceeds the combined rigidity of the coverimg materials. By “self-locking” of the article in the briefs, the use of particular fastening means such as adhesive strips or the like may = ~ be avoided. Naturally, this is a great advantage since it considerably simplifies the handlihg of the article both when applying it to the thong arad when removing the article from the thong after use. Moreover, the production of the articles is sim plified and the production costs are reduced if fastenimg adhesive and accomepanying protection sheets can be dispensed with.

Thus, due to the facet that the side tabs are attached to the edge portions of the article such that the side tabs, without being folded, are originally directed . 15 in over the underside of the article, a number of advantages can be obtained.

It is not necessary that the attached edge portions of the fastening talos completely coincide with the long sides of the article. It can, for instance, be suitable to attach the fastening tabs at a distance of up to 7 mm from the log ) sides of the article. Further, it is possible to design the fastening tabs with an edge contour somevvhat deviating from the edge contour of the long sides ©f - the article.

In one embodiment of the invention, a fastening means is arranged at the rear end portion of the article in order to prevent the rear end portion to mowe in relation to the thong.

MORE DETAILED DESCRIPTION OF FIGURES AND EMBODIMENTS:

Figure 1 shows a sanitary towel 1 according to one embodiment of the - invention.

The sanitary towel 1 has an essentially elongate shape with a longitudinal direction and a transverse direction and it has two long sides 2.4, two short ) sides 6,8, & first end portion 10 and a second end portion 12, and a longitudinal «entre line 14, running in the longitudinal direction of the sanitary : towel, and a transverse centre line 16 running in the transverse direction of the sanitary towel. Longitudinal centre line signifies a line wh ich runs in the longitudinal direction of the sanitary towel and is arranged at equal distances from the lon g sides 2,4 of the sanitary towel. Transverse centee line signifies a line arranged in the transverse direction of the sanitary towel and at equal distances from the shor sides 6,8 of the sanitary towel. The sanitary towel 1 has an uppear side 18, intended to be directed towards the wearer during use, and an underside 20, intended to be directed away from thea wearer during use. The sanitary towel additionally has fastening tabs 26, 28 intended to secure the article in the thong.

CT WO 30/72790 PCT/SE00/00948

Tree sanitary towel 1 comprises a liquid-permeable surface lzayer 22 arranged ore that side of the sanitary towe! lintended intended to be «directed towards the wearer during use, namely the upper side 18, and a liquicd-barrier backing layer 24 arranged on that side of the sanitary towel intendead to be directed awway from the wearer during use, namely the undersidle 20. Arranged bextween the surface layer 22 and the liquid-barrier backing layer 24 there is am absorbent body 30. The surface layer 22 and the bacicing layer 24 are jogned in a seam around the absorbent body 30.

The surface layer 22 can be of any conventional materia I, for example a nonwoven, a perforated plastic film, or a laminate of a perforated plastic film ard a nonwoven.

The absorbent body 30 is preferably made of cellulose p-ulp. This can be

E 15 originally in the form of rolls, bales or sheets which, upon m anufacture of the sanitary towel, are dry-defibred and converted in fluffed foram to a pulp web, sometimes with admixture of so-called superabsorbents, which are polymers having the ability to absorb several times their own weight of water or body ) fluid. An alternative to this is to dry-form a pulp web as «described in WO 94/10956. Examples of other absorption materials that can be used are : various types of natural fibres such as cotton fibres, peat, or the like. it is of course also possible to use absorbent synthetic fibres, or mixtures of natural fibres and synthetic fibres. The absorbent body 30 can also contain further components such as shape-stabilizing members, liquid-dispoersing members, or binders, for example thermoplastic fibres which have been heat-treated in order to hold short fibres and particles together in a cohereent unit. It is also prossible to use different types of absorbent foam materiaiss in the absorbent body.

The liquid barrier layer 24 or backing layer is made of a lisquid-impermeable material. Thin, liquid-tight plastic films are suitable for this gourpose, although it is also possible to use material which is originally liqu id-permeable, but y which has been provided with a coating of plastic, resin or other liquid-tight ee matermal. In this way, leakage of liquid from the underside of the absorbent on . article is prevented. The barrier layer 24 can thus be made of any desired

Sn mater®al which satisfies the requirement for liquid impermeability and has - 5S sufficient flexibility and skin compatibility for the intended purpose. Examples er of materials which are suitable as barrier layers are plastic films , nonwovens

Ce and laminates of these. The plastic film can be, for example, palyethylene, polypr-opylene or polyester. The barrier layer can alternatively bbe made of a laminate of a liquid-iimpermeable plastic layer, directed towards the absorioent body, and a nonwoven directed towards the users underwear.

Such = construction gives a leaktight barrier layer having a textile feel. : An acequisition layer 32 can be arranged between the surface | ayer 22 and - the alosorbent body 30. The purpose of the acquisition layer 32 is to draw : 15. liquid into the sanitary towel and convey it down to the absorbent body 30. - The acquisition layer 32 can be made of a low-density nonwoven material.

Figure= 2 shows a cross section through the sanitary towel 1 in Figure 1 along the lin e li-ll. On the underside 20 of the sanitary towel, that is to say on the ) 20. liquid barrier layer 24, there are fastening members 34 in the form of pressiare-sensitive adhesive strips arranged parallel to the longitiudinal centre - line off the sanitary towel. Alternatively, the fastening member can have anothexr shape, for example oval, rectangular, lines points or the like.

Arranged over the adhesive 34 there is a releasable protective layer 38. The protective layer 38 is removed by the user before placing the sanitary towel in the urderwear. Other fastening members such as hook-and-loop, snap fasteneers, friction material, gripping members or the like can of course also be usexd.

Figure 1 shows that the long sides 2,4 of the sanitary towel have an essentially arcuate shape. The arcuate shape is such that the long sides 2,4 of the sanitary towel curve in towards the longitudinal centre lime 14 of the oC : WO 00/72790 PCT/SE00/00948 sanitary towel. The long sides 2,4 of the article have two fastening tabs 26, 28 on the rear end portion. These fastening tabs 26, 28 have an essentially rounded contosur and they can have the same combinations of material as the rest of the samitary towel. It is also possible for the fastening tabs 26, 28 to consist solely of a liquid barrier layer 24 together with a surface material 22.

The fastening tabs 26, 28 can also partially comprise a soft material, such as a nonwoven, & foamed plastic or the like. It is advantageous for the material of the fasteni ng tabs to be hydrophobic, so that liquid is prevented from passing from the absorbent body 30 to the fastening tabs 26, 28.

Figure 3 shows a panty liner 36 according to one embodiment of the invention. The panty liner 36 has a surface layer 22, a barrier layer 24, an absorbent body 30 and fastening tabs 26, 28. The absorbent bady can be an . air laid cellulo se pulp body. The surface layer 22, the barrier layer 24, and the : 16 fastening tabs 26, 28 can be made of the same materials as has been : described for the surface layer 22, the barrier layer 24, and the fastening tabs 26, 28 in the embodiment of the sanitary towel according to Fig ures 1-2. ‘ Figure 4 showvwvs a section along the line IV-IV through the panty liner in Figure 3. On the underside 20 of the panty liner, that is to say on its liquid barrier ; layer 24, ther-e are fastening members in the form of a layer 34 of pressure- sensitive adh esive covering the entire surface. Alternatively, in the same way as in the saritary towel in Figures 1 and 2, the fastening member can have another shape, for example oval, rectangular, lines, points or the like.

Arranged ovesr the adhesive layer 34 there is a releasable protective layer 38.

The protectiwe layer 38 is removed by the user before placimg the sanitary towel in the underwear. Other fastening members such as hook-and-loop, snap-fastene=rs, friction material, gripping members or the likes are of course also possible=.

Figure 5 shosws an article 42 according to one embodiment of the invention.

The article 4-2 has a surface layer 22, a barrier layer 24, an absorbent body

.. 30, fastening tabs 26, 28 and a raised portion 40. The absorbent body 30 can a be made of the same materials as has been desscribed for the absorbent vr : bo dy 30 in the sanitary towel 1 according to Figures 1-2 or the absorbent

CT bo dy 30 in the panty liner 36 according to Figures 3-4. The surface layer 22, ue 5 the barrier layer 24, and the fastening tabs 26, 28 can be made of the same ee materials as has been described for the surface layer 22, the barrier layer 24, = an d the fastening tabs 26, 28 in connection with thes sanitary towel according to Figures 1-2. The raised portion 40 can be made of the same sort of ab sorption material as the absorbent body, although combinations of these

RE 10 maaterials are of course possible within the scope of the invention.

Figure 6 shows a section along the line Vi-VI through the article in Figure 5.

Or the underside 20 of the article, that is to say on its liquid barrier layer 24,

Ll there are fastening members in the form of a layer- 34 of pressure-sensitive

E 15 adhesive covering the entire surface. Altematively, the fastening member 34 oe can have another shape, for example oval, rectangular, lines, points or the like. Arranged over the adhesive layer 34 there is a releasable protective layser 38. The protective layer 38 is removed by the user before placing the sa nitary towel in the underwear. Other fastening me ambers such as hook-and- ’ loop, snap-fasteners, friction material, gripping me mbers or the like are of co urse also possible. ’

Figures 7-11 show articles according to alternative embodiments of the invention. What distinguishes these articles from those described in connection with figures 1-6 is that the fastening m ember 34 is arranged in arvother way. The liquid-barrier backing layer 24 iss advantageously able to breathe. Such a breathable backing layer 24 can, for example, be made of an

SMS (spunbond-meltblown-spunbond) material or a breathable plastic film, for example comprising polyethylene. Such a plasti c film is described in EP 283 200. If the breathability of the backing layes 24 is to be used, the underside 20 of the absorbent article cannot be completely covered by a vapour-tight fastening member 34. In Figures 7 and 8, the fastening member

28-06-2001 SE0000948

IE 15 34 is therefore arranged in three areas 34a, 3-4b, 34c, with intermediate exposed areas of the backing layer 24. Figures 9 and 11 show absorbent articles where the fastening areas 34a and 34c are arranged only at the wider end portion of the article and on the fastening tabs 26, 28. It is of course possible to conceive of application patterms for the fastening member other than those shown in the figures. For example, the fastening member can be arranged in a continuous point pattern, a met pattern or similar pattern which allows gas an vapour to pass through the backing layer 24.

The fastening member preferably consists of adhesive, but it can also comprise mechanical fastening arrangements such as hook-and-loop, snap- fasteners, friction coatings, gripping members or the like.

Figure 10 shows an embodiment in which a breathable fastening film has 1% been applied across the whole of the underside 20 of the article so that the adhesive coating functions as a combined b arrier layer and fastening member. . | : _ : Figures 12 and 13 show a sanitary towel 50 according to an embodiment of the invention. The sanitary towel 50, for instance of the type shown in Figures : "17and 2, has fastening tabs 56, 58 which corsist of separate pieces of material. The fastening tabs 56, 58 have edge portions 52,53,54,55 wherein a first edge portion 52,54 is firmly secured alon g the long sides 2,4 of the backing layer 24 on the protruding edge portioms of the sanitary towel 50.

The difference between the sanitary towel 50 and the sanitary towel 1 in

Figures 1 and 2 is that the fastening tabs 56, 58 -are arranged such that they ’ from the start extend in over the backing layer 24, past the longitudinally extending centre line 14 so that the fastening tabs 56, 58 at least partially overlap. However, the fastening tabs 56, 58 hawe a width in the transverse direction of the sanitary towel 50 which is less th an the width of the sanitary towel 50. Further, it is evident from Figure 12 that the fastening tabs 56, 58 are partly arranged at the second, rear end portion 12. In Figure 12 it can

AMENDED SHEET

"28-06-2001 SE0000948

Co 16 also be seen that the fastening tabs 56, 58 do not extend over the full length of the sanitary towel 50 something which would have been less advanta geous since it would have detracted from the desired discretion which is a reason for wearing thongs. Accordingly, it #s suitable to arrange the fastening tabs 56, 58 at a distance of 0.5 to 2 cm from the rear end side 8 whereby a soft, discrete outer end portion is obtained. In addition, it is suitable to arrange the fastening tabs 56, 58 at a distance from the front end side 6 simce the adaptability to different sizes and shapes of thongs otherwise would be diminished. Naturally, it is possible to arramge fastening tabs along all of thes length of the article although such an embodiment is normally less preferred.

On the s anitary towel 50 fastening means 34 in the form of two rectangular areas 34a, of pressure-sensitive adhesive is arranged on the liquid barrier 16 layer 24 on the first end portion 10 and on the second end portion 12. In order to facilitate positioning of the sanitary towel 50 in the thong, it is advantageous not to arrange pressure-sensitive adhesive on the area of the. ..-. liquid ba rrier layer 24 which coincides with the fastening tabs 56, 58.

Furthermore, by not arranging pressure-sensitive adhesive in said area, the sanitary Towel 50 in accordance with this embodiment has the particular ’ ‘advantage of being able to move freely in relation to the thong and accordingly to more freely adapt to the user's body movements. In Figures 12 and 13 it can be seen that the fastening tabs 56, 58 are also provided with fastening means 34c. The fastening means 34c, are arranged on the side of the fastering tabs 56,58 which faces the backing layer 24. Thus, the inner fastening tab 58 will be attached to the thong and the outer fastening tab 56 will be att=ached to the side of the fastening tab 58 which faces away from the backing layer 24. In accordance with this embodimen t, the fastening means 34c, cons-ist of friction material, for instance elastic foam material which is advantageous since the material in thongs often consists of fragile materials and, for this reason, could be damaged or destroyed by a fastening means consisting of an adhesive layer which would attach more firmly to the cloth.

Another advantage with a sanitary towel 50 in accordance with this embodiment is that the fastening tabs 56,58 will exhibit a certain degree of rigidity as an additional effect of the friction material something which will facilitate the application of the sanitary towel 50 in the thong. Naturally, it is

S possible to arrange the fastening tabs in the reverse order to what is shown in the Figures. Corssequently, the fastening tab 56 which is arranged outermost in Figures 12 and 13 can instead be attached to the thong and the fastening tab 58 which in the Figures is attached to the thong can be attached outermost.

Evidently, it is possible to produce an article of the kind described in connection with Figures 12 and 13 without fastening means since the sanitary towel 50 when worn in thongs will conform to the body of the user and will acquire a longitudinally arcuate configuration. As has been previously mentioned, such longitudinal curving creates tensional forces in the fastening tabs 56, 58 on the outside of the thong, whereby the fastening ee tabs 56,58 press against the thong so that the thong material is clamped BE between the fastening tabs 56,58 and the liquid barrier layer 24. In this manner, the sanitary towel 50 is kept in place in the thong and the use of special fastening means such as, for instance, pressure-sensitive adhesive, ) "hook-and-loop fasteners, press studs, friction coatings, clasps or the like can be avoided.

A further embodiment of the invention is shown in Figures 14 and 15 which show a panty liner 60, for instance of the kind shown in Figures 3 and 4. The difference between the panty liner 60 and the one which is shown in Figures 3 and 4 is that is has fastening tabs 66,68 which are arranged in a manner similar to that described in relation to the sanitary towel in Figures 12 and 13,

In Figure 14 it can be seen that the fastening tabs 66, 68 extend over a smaller part of the total length of the panty liner 60 than the fastening tabs 56, 58 which are show n in Figure 12. The fastening tabs 66, 68 are arranged substantially centrally along the long sides 2,4. The fastening tabs 66, 68
