Definitions

• the invention relates to an absorbent article which is designed to be worn together with thong underwear.
• an absorbent article such as a sanitary towel, an incontinence protector or a panty liner, adapted to these types of briefs.
• 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 model 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 describes panty liners intended to be worn in thongs and provided with fastening tabs.
• the fastening tabs are located both on the first end portion, which is the wider portion of the article, and also on the second end portion, which is the narrower portion of the article.
• the disadvantage of an article according to this patent is that there are a large number of tabs for the wearer to fasten to the briefs and that two of these tabs are placed on the first end portion of the article, which reduces the adaptability to different shapes and sizes 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 during use, which takes away from the advantage of wearing thongs.
• the fastening tabs have an essentially rounded contour.
• the fastening tabs are provided with fastening means in the form of fastening adhesive or some type of mechanical fastening arrangement, for example hook-and-loop fasteners, snap fasteners, friction-type fasteners or the like. It is also possible to use combinations of mechanical and adhesive fastening members.

• the length of the article is advantageously 150 mm or less.
• Liquid barriers can also be arranged between the absorbent part of the article and the fastening tabs.
• Such liquid barriers can consist, for example, of liquid-blocking welds, compressions, liquid-repelling material such as wax, plastic or the like.
• the fastening tabs can be made of a hydrophobic material such as a hydrophobic nonwoven, plastic or the like.

• the absorbent article is constructed with its rear portion so arranged that the article is not visible from outside when placed in thong underwear, and that at least this portion is provided with fastening tabs.
• the absorbent article It is advantageous for the absorbent article to follow 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 therefore 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.
• the fastening tabs have a rounded contour 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 further enhance the comfort of the article by making the fastening tabs from a soft, comfortable material such as a nonwoven, a foamed plastic, or the like. To hold 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 by providing the fastening tabs with some form of fastening arrangement, for example adhesive, hook-and-loop, snap fasteners, friction- type fasteners, or the like.

• this fastening arrangement can also have a special shape so that the user can, for example, avoid having fastening adhesive across the entire reverse side of the product.
• 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.

• fastening tabs In order to reduce the risk of side leakage, it is advantageous if no direct connection exists between the cover or the absorption body of the article and the fastening tabs.
• fastening tabs By arranging fastening tabs in the form of separate, discrete pieces of material on the article, the join between the tabs and the rest of the article will form a kind of leakage barrier, whereby all fluid transport paths to the fastening tabs will be cut off.
• 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.
• 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 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. 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 separate pieces of material or the tabs on the side of the article which during use is intended 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 article, i.e. the side of the article which faces away from the user.
• the article is curved in the longitudinal direction in order to conform to the body of the user.
• tensional forces are created in the tabs, causing these to press against the cover material on the underside of the article and clasping the leg edges of the thong between the tabs and the remaining parts of the article.
• the fastening tabs exhibit a certain rigidity, 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 covering materials.
• fastening tabs it is not necessary that the attached edge portions of the fastening tabs 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 long sides of the article. Further, it is possible to design the fastening tabs with an edge contour somewhat deviating from the edge contour of the long sides of the article.
• a fastening means is arranged at the rear end portion of the article in order to prevent the rear end portion to move in relation to the thong.

• the protection layer is release coated on both sides whereby it serves as a protection layer both for the fastening means 34a, 34b on the liquid barrier layer 24 and for the fastening means 34c on the fastening tabs 66, 68.
• the fastening means can, for example, have the shapes which are shown in Figures 12 and 14 but it is also possible to conceive of other shapes, as has been described in connection with Figures 2 and 4. Naturally, it is also possible to conceive other application patterns than those shown in figures 12 an 14.
• a further embodiment of the invention, which is not shown in the Figures, is to arrange the fastening tabs so that they extend in over the liquid barrier layer 24 ending at a distance from the longitudinal centre line 14 so that the second, free edge portions 53, 55 borders on an intermediate exposed portion of the backing layer 24.
• fastening tabs 56,58; 66,68 consist of a laminate comprising a more rigid material.
• the more rigid material is preferably arranged between two covering layers which are joined at the periphery of the more rigid material.
• the more rigid material may consist of a sheet of rigid plastic material, cardboard, board or the like.
• the shape of the fastening tabs in Figures 1-11 can, for instance, be applied to articles of the kind shown in Figures 12-15. Furthermore, it is optional to provide the articles with a protrusion such as the one described in connection with Figures 5 and 6.
