Description

Technical field

The invention relates to an absorbent article which is designed to be worn together with tango panties.

BACKGROUND OF THE INVENTION

Contemporary fashion with garments close to the body makes it becoming common to wear so-called "tango" panties that have a very narrow crotch area.

As the wearing of the "tango" panties became more common, the demand for an absorbent article, such as a sanitary napkin, incontinence protection or a panty liner adapted to this type of panties, also increased.

Conventional absorbent articles are generally rectangular or tapered in shape. However, rectangular or tapered products protrude beyond the edges of the tango panties and detract from the elegance that is the main reason for wearing this type of linen. A possible alternative is to make the product narrow enough to fit the entire width of the product between the edges of the narrowest part of the "tango" panties. It has been proposed to produce absorbent articles with a shape that is identical to that of the tango panties. See, for example, SE 9803981-1 and WO 97/39713. SE 9803981 discloses an absorbent article which is characterized by the fact that the width of the rear end portion of the article is at most 40 mm and that the long sides of the end portion are substantially bent. Although such a product works satisfactorily in terms of confidentiality, it has proven difficult to place the product so that it will sit securely in its tango pants during use.

Thus, one of the most important problems to be solved in absorbent articles for this type of panties is its fastening in the panties because the tango area of the panties in the crotch is very small. It is also important for various reasons that the product fits precisely in the "tango" panties. On the other hand, incorrect product placement causes the user's discretion and comfort to deteriorate, and in addition to what is most important with regard to the product's small surface area, it must be positioned in such a way that it is capable of receiving and absorbing all excreted body fluids. . The safe and correct fastening of the product is therefore also important for leakage.

US Des. No. 394,503 discloses a product having a shape which is intended to fit into a " tango " panties and is additionally provided with protruding side protrusions. The protrusions in this model have a rectangular shape with sharp edges. A winged product of this type can cause discomfort because the sharp edges of the protrusions scuff or cut the user during use.

US 5,713,886 discloses panty liners intended to be worn in "tango" briefs and provided with fastening tabs. The fastening lugs are located on the first end portion, which is the wider part of the product, and also on the second end portion, which is the narrower part of the product. A disadvantage of the article according to this patent is that a large number of tabs are located on the first end portion of the article, which reduces its adaptability to the different shapes and sizes of the tango panties. Another disadvantage of the product of US 5,713,886 is that the protrusions on the wider end portion are visible during use, which detracts from the benefits of wearing "tango" panties.

SUMMARY OF THE INVENTION

An article of the type discussed in the introduction, and in which the problems associated with prior art products of this kind have been substantially eliminated, is characterized in accordance with the invention in that at least the second, rear end portion has resilient fastening tabs for fastening the article in tango .

According to a preferred practical embodiment, the fastening projections have substantially rounded contours. According to another practical embodiment, the fastening tabs are provided with fastening means in the form of a fastening adhesive or some type of mechanical fastening mechanism, for example hook-loop fasteners, snap fasteners, friction type fasteners and the like. It is also possible to use combinations of mechanical and adhesive fasteners. According to one practical embodiment, the fastening lugs are secured against each other. According to another practical embodiment, the fastening tabs comprise a soft material, such as a nonwoven material, foamed plastic, and the like.

In order to be able to attach the article also to the front edge of the panties, the front end portion is preferably provided with a fastening mechanism. Such a fastening mechanism may consist of a fastening adhesive element or a mechanical fastening mechanism, for example a friction coating, hook-loop materials, fasteners, snap fasteners and the like. The fastening mechanism on the front of the article may have a particular shape, e.g.

oval, rectangular, stripes and the like. To facilitate the proper placement of a product of this type discussed in the introduction, in a preferred practical embodiment, the product may have a raised edge. In this way, it is also possible to increase the absorption capacity of the product and to increase the safety against leakage. According to another practical embodiment, the article has inwardly curved side edges in order to better fit the edges of the tango at the legs.

According to one practical embodiment, the width of the rear end portion is 15 to 40 mm and preferably 18 to 30 mm. In order to fit the product in "tango" pants, the length of the product is preferably 150 mm or less.

Liquid barriers may also be positioned between the absorbent portion of the article and the fastening tabs. Such fluid barriers may include, for example, fluid blocking welds, compression, liquid-repellent material, such as wax, plastic, and the like. It is also possible for the attachment lugs to be made of a hydrophobic material, such as a hydrophobic nonwoven material, plastic, and the like.

According to one practical embodiment of the invention, the fastening tabs are made of separate pieces of material, wherein each fastening tab has an edge portion that substantially overlaps with a corresponding edge portion on the long side, and wherein the fastening tabs and edge portions are interconnected by overlapping edge portions, wherein the fastening projections are oriented opposite to each other and with the unbonded edge portions overlap the absorbent body on the underside, i. j. on the side of the product to be turned away from the user during use.

According to one practical embodiment of the invention, the rear end portion is provided with a fastening mechanism for attachment in "tango" panties.

Description of the invention

According to the present invention, the above problems are solved so that the absorbent article is constructed with a back portion resolved in such a way that the article is not visible from the outside when placed in the "tango" panties, and so that at least this portion is provided with fastening projections.

For an absorbent article, it is preferable to mimic the shape of the panty edges so that the available absorbent surface is as large as possible. An article that is as wide as possible is also important in terms of fluid leakage. The risk of leakage from the side of the panties as well as the coloration of the panties is minimized when the product is adapted to the shape of the panties. The absorbent article of the invention therefore has long sides that follow the contours of the panties in the crotch region. A product that closely follows the shape of the panties will also be very well concealed during use.

It is very important that an article having a smaller absorbent surface than a conventional absorbent article, such as the article of the present invention, fits correctly and securely in place in the panties, because an article having such a small absorbent surface that moves in the panties, it is unusable for leakage. According to the invention, the attachment of the article is ensured by the fact that the article has long sides which follow the contours of the panties in the crotch region and which is provided with fastening projections.

In a preferred practical embodiment of the invention, the fastening tabs have rounded contours to avoid chafing and discomfort to the wearer, which may be caused by the angled edge tabs. It is also possible to further enhance the convenience of the product by making the fastening tabs of a soft, comfortable material such as a nonwoven, foamed plastic and the like. To keep the absorbent article in place in the "tango" panties, it is important that the fastening tabs are attached to each other or with the "tango" panties. This is best achieved by the fastening projections having some kind of fastening mechanism, for example, an adhesive, a hook-loop, a snap, a friction tab and the like.

In order to achieve maximum protection against fluid leakage, it is preferred that the first end portion of the article can also be properly fitted in the pant. In order to allow the user the widest choice in terms of positioning the article in the panties, fastening means comprising an adhesive means or a mechanical fastener are preferred. This provides the user with a product that is easily attached to the panties and which can also move in a simple maneuver if the user feels that the first position was not correct. To further simplify the situation for the wearer, the fastening mechanism may have a special shape so that the wearer may, for example, avoid having a fastening adhesive over the entire width of the opposite side of the article.

Many tests have shown that to reduce fluid leakage when using an absorbent article, it is useful for the article to be in contact with the fluid as close to the body as possible. A preferred way to achieve this is to provide the product with a raised portion. This will also increase the absorption capacity. The raised portion additionally functions as a positioning element.

Surprisingly, it has been found that the width of most of the crotch panties is more or less the same. Measurements have also shown that the width of the absorbent article, not exceeding 40 mm, is in most cases sufficiently small to hide in "tango" panties.

The width is preferably 15 to 40 mm.

It has been found that there is no need for the entire product to have a specified, very small width, since the front of most of the tango panties on the market is wide enough to allow the use of a normal width product with more or less arbitrary contour on the long side. This means that the part of the product that is placed on the front of the user may have a looser structure depending on the absorption capacity requirements.

It follows that only the end part to be placed on the back of the wearer and belonging to the narrow part of the 'tango' of the panties must have a structure of maximum width and a special outline of the long sides. This part of the product will hereinafter be referred to as the rear or second end portion. The portion of the article that may have a looser structure is referred to herein as the front or first end portion. These two end portions do not necessarily divide the product into two equal portions in 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 total length of the product is therefore 90 to 260 mm.

In order to reduce the risk of fluid leakage on the sides, it is preferred that there is no direct connection between the packaging or absorbent body of the article and the fastening tabs. When forming the fastening tabs in the form of separate, separate pieces of material on the article, the joint between the tabs and the remainder of the article will form some kind of fluid leakage barrier, thereby interrupting all fluid transport paths to the fastening tabs. In addition to the fastening projections consisting of separate pieces of material, the composition and other properties can be chosen freely, irrespective of the materials forming the article coating. Furthermore, it is possible to produce products with negligible material losses during punching. Due to the fact that the fastening projections are formed by separate pieces of material that are positioned and fastened on the long sides of the product in such a way that the fastening projections protrude against each other inwardly over the bottom of the product, i. j. on the side of the product to be turned away from the user during use, it is possible to produce a product in which the mounting lugs in their initial configuration do not point outwards

Ί from the product. It follows that the products are easy to pack because the handles do not require a special folding operation.

Another advantage of attaching separate pieces of material or protrusions on the sides of the article, which during use should be turned away from the wearer, is that the conventional square edge portions of the article and side protrusions can be shaped to follow the curved edges of the leg openings in the tango. This implies that the protrusions do not warp or distort in any other way as a result of attachment in the 'tango' panties, something that usually happens with side protrusions that fold over the edges of the panties. Further, when the article is placed in the "tango" panties, the edges of the "tango" panties around the legs extend between the protrusions and the covering material on the underside of the article, i. on the side of the product that faces away from the user. During use, the product is folded in the longitudinal direction to accommodate the user's body. This creates tensile forces in the projections causing them to be pressed against the packaging material on the underside of the product and gripping the edges of the tango of the panties around the legs between the projections and the rest of the product. In order to achieve the maximum of such a "self-locking", it is advantageous if the fastening tabs have a certain stiffness, i. j. they are stiffer than each of the cover layers, and the strength of the fastening projections preferably exceeds the combined rigidity of the packaging materials. By "self-locking" the product in the panties, it is possible to avoid using fasteners such as adhesive tapes and the like. Naturally, this is a great advantage, because it greatly simplifies the handling of the product when inserting it into the tango panties as well as removing the product from the tango panties after use. In addition, production of the product is simpler and production costs are reduced if it is possible to dispense with the adhesive and the accompanying protective layers.

Thus, due to the fact that the side protrusions are connected to the peripheral portions of the article such that the side protrusions, without being overlooked, initially inwardly over the bottom of the article, provide a number of advantages.

There is no need for the attached edge portions of the mounting lugs to completely overlap with the long sides of the product. For example, it may be desirable to attach the mounting lugs at a distance of up to 7 mm from the long sides of the article. Further, it is possible to provide fastening projections whose edge contours slightly deviate from the edge contours of the long sides of the article.

In one practical embodiment of the invention, the fastening means is located in the rear end portion of the article to prevent movement of the rear end portion relative to the "tango" panties.

DETAILED DESCRIPTION OF THE INVENTION

Figure 1 shows a sanitary napkin 1 according to one practical embodiment of the present invention.

The sanitary napkin 1 has a substantially elongated shape with a longitudinal and transverse direction and has two long sides 2,4, two short sides 6,8, a first end portion 10 and a second end portion 12, and a longitudinal centerline 14 extending in the longitudinal direction of the sanitary napkin. and a transverse centerline 16 extending in the transverse direction of the sanitary napkin. The longitudinal centerline means a line extending in the longitudinal direction of the sanitary napkin that is equidistant from the lateral sides of the sanitary napkin. The transverse centerline means a line oriented in the transverse direction of the sanitary napkin that is equidistant from the short sides of the sanitary napkin 6.8. The sanitary napkin 1 has an upper side 18 to be facing the user during use and a lower side 20 to be facing away from the user during use. In addition, the sanitary napkin has fastening tabs 26, 28, which are intended to hold the article in "tango" panties.

The sanitary napkin 7 comprises a liquid-permeable surface layer 22 disposed on that side of the sanitary napkin 7 that is to be facing the wearer, in particular on the upper side 18, and a base layer forming a liquid barrier 24 disposed on that side of the sanitary napkin. An absorbent body 30 is provided between the surface layer 22 and the base layer forming the liquid barrier 24 during use. The surface layer 22 and the base layer 24 are joined in a skirt around the absorbent body 30.

The surface layer 22 may be of any conventional material, for example a nonwoven material, a perforated plastic film, or a layered structure of the perforated plastic film and the nonwoven material.

The absorbent body 30 is preferably made of cellulose pulp. This may initially be in the form of rolls, bales or sheets, which in the manufacture of sanitary napkins are dry disintegrated and converted into a pulp web, sometimes with the addition of so-called superabsorbents, which are polymers capable of absorbing body fluid at several times their weight. An alternative to this is the formation of a dry cellular network as described in WO 94/10956. Examples of other absorbent materials that can be used are various types of natural fibers, such as cotton fibers, peat and the like. It is of course also possible to use absorbent synthetic fibers or mixtures of natural fibers and synthetic fibers. The absorbent body 30 may also comprise other components, such as shape stabilizing components, liquid dispersing components or binders, for example thermally treated heat-treated fibers, to hold the short fibers and particles together in a cohesive unit. It is also possible to use different types of absorbent foam materials in the absorbent body.

The liquid barrier layer 24 or base layer is made of a liquid impermeable material. Thin liquid-impermeable thin plastic films are suitable for this purpose, although it is also possible to use a material that is initially liquid-permeable but on which a coating of plastic, resin or other liquid-impermeable material has been applied. In this way, liquid leakage from the bottom of the absorbent article is prevented. Thus, the barrier layer 24 can be made of any desired material that meets the requirements of liquid impermeability and has sufficient elasticity and is well tolerated on the skin in the intended use. Examples of materials suitable as barrier layers are plastic films, nonwoven materials or layered structures of these materials. Plastic foils can be, for example, polyethylene, polypropylene or polyester. The barrier layer can also be made of a layered structure formed by a layer of liquid impermeable plastic placed on the side of the absorbent body and a nonwoven material placed on the side of the wearer's underwear. Such a structure forms an impermeable layer to prevent leakage of liquid which acts as a textile on the feel.

An acquisition layer 32 may be disposed between the surface layer 22 and the absorbent body 30. The purpose of the acquisition layer 32 is to draw liquid into the sanitary napkin and drain it down into the absorbent body 30. The acquisition layer 32 may be made of a low density nonwoven material.

Figure 2 shows a cross-section of the sanitary napkin 1 of Figure 1 along the axis II-II. At the bottom 20 of the sanitary napkin, in other words on the liquid barrier layer 24, fasteners 34 in the form of pressure-sensitive adhesive tapes are disposed parallel to the longitudinal centerline of the sanitary napkin. It is also possible for the fastener to have a different shape, such as oval, rectangular, dashes, dots and the like. A removable protective layer 38 is deposited on the adhesive layer 34. The protective layer 38 is removed by the user before placing the sanitary napkin in the laundry. Of course, other fasteners, such as hook-loop, snap fastener, friction material, fasteners and the like can also be used.

Figure 1 shows that the long sides 2,4 of the sanitary napkin have a substantially curved shape. The arched shape is such that the long sides 2,4 of the sanitary napkin are bent inwardly toward the longitudinal centerline 14 of the sanitary napkin. The long sides 2,4 of the article have two fastening lugs 26, 28. at the rear end. These mounting lugs 26, 28. they have substantially rounded contours and may be of the same material combinations as the rest of the sanitary napkin. It is also possible that the mounting lugs 26, 28. they consist solely of the liquid barrier layer 24 together with the surface material

22. Fastening lugs 26,28. they may also partially comprise a soft material, such as a nonwoven material, foamed plastic, and the like. Preferably, the material of the fastening tabs is hydrophobic such that fluid cannot penetrate from the absorbent body 30 into the fastening tabs 26.28.

Figure 3 shows a panty liner 36 according to one practical embodiment of the present 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 body may be an airlaid cellulose pulp body. The surface layer 22, the barrier layer 24 and the fastening tabs 26, 28 may be made of the same material as described for the surface layer 22, the barrier layer 24, and the fastening tabs 26, 28. in the practical embodiment of the sanitary napkin of Figures 1-2.

Figure 4 shows a cross section along the IV-IV axis through the panty liner in the figure

3. On the underside 20 of the panty liner, in other words on its liquid barrier layer 24, there are fasteners in the form of a pressure-sensitive adhesive layer 34 covering the entire surface. Another possibility is that, as in the sanitary napkin of Figures 1 and 2, the fasteners are of a different shape, for example oval, rectangular, dashes, dots and the like. A removable protective layer 38 is provided on the adhesive layer 34. The protective layer 38 is removed by the user before placing the sanitary napkin in the laundry. Other fasteners such as hook-loop, snap fasteners, friction material, fasteners and the like are of course also possible.

Figure 5 illustrates an article 42 according to one practical embodiment of the present invention. The article 42 has a surface layer 24, an absorbent body 30, fastening projections 26, 28. and the raised portion 40. The absorbent body 30 may be made of the same material as described for the absorbent body 30 in the sanitary napkin 1 of Figures 1-2, or the absorbent body 30 in the panty liner 36 of Figures 3-4. The surface layer 22, the barrier layer 24 and the fastening tabs 26, 28. they may be made of the same material as described for the surface layer 22, barrier layer 24, and fastening tabs 26.28 in connection with the sanitary napkin of Figures 1-2. The raised portion 40 may be made of the same type of absorbent material as the absorbent body, of course, combinations of these materials are possible within the scope of the invention.

Figure 6 shows a cross section along the axis VI-VI of the article of Figure 5. On the underside of the article 20, in other words, on the liquid barrier layer 24, the fastening tabs are in the form of a pressure sensitive adhesive layer 34 covering the entire surface. Alternatively, the fastener 34 may have a different shape, such as oval, rectangular, dashes, dots, and the like. A removable protective layer 38 is disposed on the adhesive layer 34. The protective layer 38 is removed by the wearer before placing the sanitary napkin in the laundry. Other fasteners such as hook-loop, snap fasteners, friction material, fasteners and the like are of course also possible.

Figures 7-11 illustrate articles according to other practical embodiments of the invention. What distinguishes them from the products described in connection with Figures 1-6 is that the fastening element 34 is positioned differently. The base layer forming the liquid barrier 24 is preferably breathable. Such a breathable base layer 24 may, for example, be made of an SMS (interwoven-fused-interwoven) material or a breathable plastic film, for example polyethylene. Such a plastic film is described in EP 283 200. If the breathability of the base layer 24 is used, the lower part 20 of the absorbent article cannot be completely covered by the vapor-impermeable fastening element 34. In Figures 7 and 8, therefore, the fastening element 34 is disposed on three surfaces 34a, 34b, 34c with exposed surfaces of the base layer 24 lying therebetween. Figures 9 and 11 show absorbent articles in which fastening surfaces 34a and 34c are located only on the wider end portion of the article and on fastening tabs 26, 28. It is, of course, possible to envisage other application patterns for the fastener than those shown in the figures. For example, the fastening element may be in the form of a continuous dot pattern, mesh pattern or the like that allows gas and steam to pass through the base layer 24.

The fastener is preferably an adhesive, but may also include mechanical fasteners such as hook-loop, snap fasteners, friction coatings, fasteners and the like.

Figure 10 shows a practical embodiment in which a breathable fastening film has been applied to the entire underside 20 of the article such that the adhesive coating serves as a combination of the barrier layer and the fastener.

Figures 12 and 13 show a sanitary napkin 50 according to a practical embodiment of the present invention. The sanitary napkin 50, for example of the type shown in Figures 1 and 2, has fastening projections 56, 58 that are separate pieces of material. Fastening lugs 56,58. have edge portions 52,53, 54,55, in which the first edge portion 52,54 is fastened along the long sides 2,4 of the base layer 24 on the protruding edge portions of the sanitary napkin 50. The difference between the sanitary napkin 50 and the sanitary napkin 1 on 1 and 2 is that the fastening lugs 56, 58. they are positioned such that from the outset they project inwardly over the base layer 24, beyond the longitudinally extending central axis 14, so that the fastening projections 56,58. at least partially overlap. Fastening lugs 56,58. however, in the transverse direction of the sanitary napkin 50, they have a width that is smaller than the width of the sanitary napkin 50. Further, it is apparent from Figure 12 that the fastening projections 56, 58. It is also seen from Figure 12 that the fastening projections 56, 58 do not reach the full width of the sanitary napkin 50, which would be less advantageous as this would reduce the required discretion, which is the reason for wearing thong. Accordingly, it is desirable to locate the mounting lugs 56.58. at a distance of 0.5 to 2 cm from the rear end side 8 to provide a soft, discrete outer end portion. In addition, it is advisable to locate the mounting lugs 56, 58. some distance from the front end side 6, because otherwise the adaptability to different sizes and shapes of tango would be reduced. It is naturally possible to locate fastening projections along the entire length of the article, although such a practical embodiment is usually less preferred.

The fastening means 34 in the form of two rectangular surfaces 34a of the pressure-sensitive adhesive are placed on the sanitary napkin 50 on the liquid barrier forming layer 24 at the first end portion 10 and the second end portion 12. To make it easier to fit the sanitary napkin 50 in tango pants it is preferable not to place the pressure-sensitive adhesive on that surface of the fluid barrier layer 24 which overlaps with the mounting lugs 56.58. Furthermore, by not placing the pressure-sensitive adhesive on said surface, the sanitary napkin 50, in accordance with this practical embodiment, acquires the particular advantage that it can move more freely relative to the "tango" of the panties and consequently more easily adapt to the movement of the user's body. 12 and 13, it is seen that the mounting lugs 56.58. they are also provided with fastening means 34c. The fastening means 34c is located on the side of the fastening tabs 56,58 that faces the base layer 24. Thus, the inner fastening tab 58 is fastened to the "tango" of the pant and the outer fastening tab 56 is fastened to the fastening tab 58 that According to this practical embodiment, the fastening means 34c are formed by a frictional material, for example an elastic foam material, which is advantageous because the material in the "tango" panties often contains fine materials and could therefore be damaged or destroyed fastening means formed by an adhesive layer that would adhere more firmly to the fabric.

Another advantage of the sanitary napkin 50 in accordance with this practical embodiment is that the fastening tabs 56,58 will have some degree of stiffness as an additional effect of the friction material, which facilitates the placement of the sanitary napkin 50 in "tango" panties. It is naturally possible to position the fastening lugs in the reverse order of the ones shown in the figures. Thus, the fastening projection 56, which is disposed externally in Figures 12 and 13, may instead be fastened to the "tango" of the pant, and the fastening projection 58, which is fastened to the "tango" of the pant, may be fastened from the outside.

It is obviously possible to make an article of the kind described in connection with Figures 12 and 13 without the fasteners, since the sanitary napkin 50 housed in the "tango" panties adapts to the body of the user and takes a curved shape in the longitudinal direction. As mentioned earlier, such longitudinal deflection will create tensile forces in the fastening lugs 56, 58. on the outside of the tango, whereby the fastening tabs 56,58 are pressed against the "tango" of the panties so that the tango material is clamped between the fastening tabs β p

56.58 and the liquid barrier layer 24. In this way, the sanitary napkin 50 holds in place in the " tango " pant and using special fasteners such as pressure sensitive adhesive, hook-loop fasteners, fastening buttons, friction coatings, staples and similarly, it can be avoided.

Another practical embodiment of the invention is shown in Figures 14 and 15, which show a panty liner 60, for example of the kind shown in Figures 3 and 4. The difference between the panty liner 60 and that shown in Figures 3 and 4 is that 12 and 13. From FIG. 14, it can be seen that the mounting lugs 66.68 extend over a minor portion of the entire length of the panty liner 60. FIG. than the mounting lugs 56.58. 12, which are shown in Figure 12. they are located essentially centrally along the long sides 2,4. Fastening lugs 66,68. protrude inwardly over the liquid barrier forming layer 24 so that their free end portions 63, 65. meet at the longitudinal centerline 14 of the panty liner 60.

In addition, the liquid barrier layer 24 of the panty liner 60 is provided with fastening means 34 in the form of rectangular surfaces 34a. 34b of the pressure sensitive adhesive disposed parallel to the longitudinal centerline 14 of the panty liner 60 in the first end portion 10 and the second end portion 12. In order to facilitate placement of the panty liner 60 in "tango" panties, it is preferred not to place the pressure sensitive adhesive on that portion of the layer forming a liquid barrier 24 that overlaps with the mounting lugs 66, 68. Furthermore, by not placing the pressure-sensitive adhesive on said surface, the sanitary napkin 60 in accordance with this practical embodiment obtains the particular advantage that it can move more freely relative to the "tango" of the pantie and thereby be more easily adapted to body movement. 14, it can be seen that the mounting lugs 66.68. they are also provided with fastening means 34c of pressure-sensitive adhesive. The fastening means 34c are located at the edge of the fastening lugs 66.68. that are facing the base layer 24.

ŕ ”

The surfaces of the pressure-sensitive adhesive are preferably protected by a removable protective layer 69 (not shown in Figure 14) prior to use. 14 and 15, the removable protective layer covers both sides and thereby serves as a protective layer for the fasteners 34a, 34b on the liquid-barrier base layer 24 and the fasteners 34c on the fasteners 66, 68.

For example, the fastening means may have the shapes shown in Figures 12 and 14, but it is also conceivable to imagine shapes other than those described with respect to Figures 2 and 4. It is naturally also possible to imagine application patterns other than those which are 12 and 14.

Another practical embodiment of the invention, which is not shown in the figures, is to locate the fastening projections such that they project inwardly over the base layer forming the liquid barrier 24 and terminate some distance from the longitudinal centerline 14 so that the second, free edge portions 53, 55 border. with an exposed portion of the base layer 24 lying therebetween.

It is also possible for the mounting lugs 56, 58; 66, 68 consisted of a layered structure containing a stiffer material. The stiffer material is preferably positioned between two cover layers which are joined at the edges of the stiffer material. The stiffer material may be a rigid plastic layer, cardboard, cardboard and the like.

It is, of course, possible to combine the characteristic features of the various practical embodiments. Thus, for example, the shape of the fastening projections in Figures 1-11 can be applied to products of the kind shown in Figures 12-15. Furthermore, it is possible to choose whether the article will have a projection as described in connection with Figures 5 and 6.

It is to be understood that the invention is not limited to the above practical embodiments. These serve only to illustrate the invention. Within the scope of the present invention, the features of the various practical embodiments may be combined with each other. Of course, the different locations of the fastening means may of course be combined with each other.
