Definitions

  • the invention relates to briefs for supporting an absorbent article, said briefs being designed with a front portion, a rear portion and an intermediate crotch portion and having two leg openings and a waist opening, and said briefs comprising a fastening member which is arranged to cooperate with a corresponding fastening member on an absorbent article for the purpose of securing the article in the briefs.
  • Such a fastening arrangement comprises a fastening member having a surface provided with loop elements and designed to cooperate with a fastening member having a surface provided with hooks or hook-like projections which can hook securely on the surface provided with loop elements.
  • the fastening members of the loop type which have been available to date generally consist of a laminate of a carrier material, for example a plastic film or a nonwoven material and an loop material, for example a loosely knitted or woven textile material or a loosely bonded nonwoven material.
  • a disadvantage of fastening members comprising a plastic layer is that they are not permeable to air and vapor, which means that such a fastening member is airtight and uncomfortable to wear against the skin. This is particularly so if large areas of skin are covered by the airtight material, as is the case when the material is used in a pair of briefs.
  • the material of the briefs is soft and gentle against the user's skin, that it does not have sharp or hard edges which can chafe the skin, and also that the material has a certain breathability and is able to let body moisture and air pass through. It is also desirable for the loop material to be inexpensive so that it can be used for disposable briefs, i.e. briefs which are discarded after a single use and are not washed or reused.
  • An object of the invention is to make available disposable briefs which comprise a fastening member provided with loops, and which briefs can be made soft and comfortable, air-permeable and vapor-permeable, and can be produced in a cost-effective manner.
  • the briefs designed according to the invention are principally distinguished by the fact that the fastening member arranged in the briefs has a surface provided with fastening loops, said fastening loops being designed to cooperate with a fastening member comprising hook members, and said fastening loops being arranged in a number of chain-like rows of loops, each formed by a continuous thread which penetrates through a layered carrier material.
  • the fastening member provided with loops, included in the briefs according to the invention can advantageously be made by one or more rows of loops being sewn into a layered carrier material. This affords several advantages.
  • fastening loops are anchored in a mechanical manner in the carrier material, which means that it is not necessary to use thermoplastic materials or other binders.
  • a further advantage of the fastening member described above is that it has a high degree of breathability since the carrier material is penetrated by the thread which forms the fastening loops. This makes the fastening member according to the invention especially suitable for use in combination with articles such as briefs which cover a large area of the skin surface when in use.
  • the fastening member is produced by means of rows of loops being sewn into a carrier material, it is also possible to increase the bendability of a stiff material so that the material is thereby easier to bend along bend lines which run parallel with the rows of loops.
  • the stiffness of the material increases transverse to the rows of loops.
  • This feature can be used to increase the stability in particularly exposed areas of the briefs.
  • the rows of loops can advantageously be arranged principally at right angles to the waist edge of the briefs, as a result of which the briefs easily bend round the user's waist, while ensuring that the material nearest to the waist edge does not bend, roll up or crease.
  • the risk of body fluid leaking out of an article worn in the briefs and extending to the waist edge increases if the waist edge is folded out onto the outside of the briefs. It is of course also uncomfortable for the user if the waist edge is folded or in some other way deformed.
  • Suitable materials for use as carrier material for a fastening member provided with loops are layered materials such as plastic film, nonwoven, or a laminate of two or more layers of plastic film, nonwoven, tissue or the like.
  • the carrier material expediently consists of a single flexible layer of nonwoven with a basis weight of about 20 g/m 2 .
  • Particularly suitable materials are spunbond materials, but other nonwoven materials such as carded material, through-air-bonded material or the like can also be used, and also different laminates.
  • the fastening loops in the fastening member provided with the loops are arranged on the inside of the briefs and in contact with the user's skin.
  • the briefs are in this case made completely or partially of material provided with loops.
  • the thread in order to be comfortable against the user's skin, must be smooth and not too coarse.
  • the thread is not absorbent, so that liquid cannot be transported in the thread.
  • absorbent thread material such as viscose and cotton.
  • the absorption properties of the thread are of less importance in some designs. In addition, the absorption properties are unimportant in areas of the briefs which are at little risk of being wetted by body fluid.
  • the thread is preferably made of nylon, polyester, polyethylene, polypropylene or the like. Voluminous threads comprising many essentially parallel fibers are preferred, and the thread's combined coarseness should be approximately 20 - 90 deniers.
  • the fastening loops expediently have a length of 2 - 10 millimeters.
  • the length of a fastening loop refers to the distance between two points of penetration in a row of loops.
  • the eyelets of the fastening member are expediently arranged in essentially parallel rows with a spacing of 1 - 10 mm between the rows. It can also be advantageous to arrange rows of loops in groups of two or more rows with a greater spacing between the groups than between the rows included in the groups. By grouping the rows of loops, it is possible to obtain zones with different properties, for example different fastening capacity, different breathability, different liquid impermeability and different stiffness. It is also possible to use the rows of loops to obtain an esthetically attractive patterns at the same time as the desired function.
  • the rows of loops can thus be distributed across the surface of the entire surface of the briefs material.
  • the fastening loops can be provided only on those parts of the briefs expected to be used for fastening an absorbent article in the briefs. These parts of the briefs are the crotch portion and, depending on the size and shape of the absorbent article, in some cases also the areas inside of the waist edge of the briefs.
  • the briefs can also be made of different types of material in different areas. In this way, it is possible to produce briefs with areas which differ in terms of properties such as elasticity, stretchability, compressibility, breathability, absorption capacity or the like.
  • Figure 1 shows a fastening member provided with loops
  • Figure 2 shows in detail a row of loops on the fastening member in Figure 1
  • Figure 3 shows a plan view of an incontinence pad, seen from the side which is directed away from the user during use
  • Figure 4 shows a pair of briefs according to the invention for supporting an absorbent article of the type shown in Figure 3, and
  • Figure 5 shows a further embodiment of a pair of briefs according to the invention.
  • this shows, on a greatly enlarged scale, an area of a fastening member 101 provided with loops and comprising a carrier material 102 which has a thread 103 forming a chain-like row 104 of fastening loops 105 on a first surface 106 of the carrier material 102, which fastening loops 105 are connected by a row of thread elements 107 which form straight stitches on the opposite, second surface 108 of the carrier material.
  • the carrier material 102 consists of a layer material, such as plastic film, nonwoven, or a laminate of two or more layers of plastic film, nonwoven, tissue or the like. Particularly preferred materials are, as has already been mentioned, soft and easily bendable nonwoven materials, for example of the spunbond type.
  • the thread which forms the fastening loops 105 can be of any suitable material and can comprise synthetic and/or natural fibers.
  • fibers of polyethylene, polypropylene, polyester, polyamide or two- component fibers such as cotton fibers, jute, flax, etc.
  • the thread is advantageously bulky and comprises in cross section a plurality of thin and substantially parallel fibers. It is also advantageous if the fibers have a certain curl since this increases the bulkiness and increases the thread's ability to cooperate with a hook member on an absorbent article.
  • the fastening member 101 comprises a plurality of rows 104 of fastening loops 105, as is shown in Figure 1.
  • Figure 3 shows an absorbent article in the form of an incontinence pad 300.
  • the incontinence pad 300 comprises a liquid-permeable cover sheet 311 , a liquid-tight cover sheet 312, and an absorption body 313 enclosed between the cover sheets 311 , 312.
  • the incontinence pad 300 is substantially hourglass-shaped with a wider front portion 331 , a wider rear portion 332, and a crotch portion 333 located between the front portion 331 and the rear portion 332.
  • the incontinence pad 300 also has two substantially longitudinal side edges 315, 316, a substantially transverse front edge 317, and a substantially transverse rear edge 318.
  • Two fastening members 325, 326 provided with hooks are arranged on the liquid-tight cover sheet 312.
  • the briefs are of conventional shape and thus have a front portion 431 , a rear portion 432 and an intermediate, narrower crotch portion 433.
  • the briefs also have a waist opening 434 and two leg openings 435, 436.
  • elastic members in the form of threads or bands are arranged as waist elastic 437 around the waist opening 434 and as leg elastic 438, 439 around the leg openings 435, 436.
  • the briefs 400 are made of a material comprising a fastening member 401 provided with loops in the form of a number of rows of loops.
  • the rows of loops can in this case be arranged in the longitudinal direction of the briefs, or in the transverse direction.
  • the longitudinal direction is understood as the direction of a line extending between the front portion 431 and the rear portion 432 via the crotch portion 433.
  • the transverse direction is at right angles to the longitudinal direction. It is of course possible to arrange the rows of loops in another direction in relation to the briefs, but this is generally less advantageous for manufacturing reasons. It is also possible to arrange the rows of eyelets as parallel straight rows, or as undulating rows, for example sinusoidal rows.
  • the fastening member 401 provided with loops can be arranged across the whole inner surface of the briefs 400, as in Figure 4, or can be applied only in those areas of the briefs which are expected to come into contact with corresponding fastening members provided with hooks on an absorbent article. Since the rows of loops are sewn into the material of the briefs, the shape and location of the fastening member 401 can be chosen by means of sewing-in fastening loops only where they are desired. Thus, it is possible to control the liquid permeability, breathability, stiffness and fastening capacity of the material of the briefs by arranging fastening loops in different areas and with different stitch lengths and closeness between the rows of loops. It is also possible to sew the fastening loops into the material of the briefs in such a way that a decorative effect is obtained at the same time as the desired functional properties.
  • Figure 5 shows briefs 500 of principally the same type as those shown in Figure 4.
  • the briefs thus have a front portion 531 , a rear portion 532 and a crotch portion 533 and have a waist opening 534 and two leg openings 535, 536 which are provided with waist elastic 537 and leg elastic 538, 539.
  • the briefs have fastening members 501a, 501b provided with loops only around the waist opening 534 on the front and rear portions 531 , 532 and on the crotch portion 533.
  • the fastening member 501a provided with loops at the waist opening 534 is arranged as a belt running around the entire circumference of the briefs, but can of course alternatively be in the form of one or more separate areas on the front portion 531 and/or the rear portion 532.
  • the fastening member 501a provided with loops at the waist opening 534 can be arranged on the inside of a conventional briefs material.
  • the part of the briefs 500 located nearest to the waist opening 534 consists of a perforated fastening member provided with loops of the type which has been described in connection with Figures 1 and 2, and if the carrier material 502 of the fastening member thus also constitutes the briefs material.
  • the briefs material within the area of the fastening member 501a can in this case be the same material as in the rest of the briefs or consists of a separate material which has been joined to the rest of the briefs material, for example by welding, adhesive bonding or stitching.
  • the fastening member 501 b in the crotch area 502 can also be in the form of a separately produced component which has been joined to the material of the briefs or can be part of the material of the briefs.
  • An advantage of using the carrier material 502 of the fastening members 501a, 501b as briefs material is that a high degree of breathability can thereby be achieved since the carrier material 502 is perforated upon attachment of the fastening eyelets 505.
  • the second fastening member 501b can be expedient to arrange the second fastening member 501b as a separate component on the inside of the briefs 500.
