Definitions
- the invention relates to an absorbent article with a longitudinal direction and a transverse direction, and with two end edges extending in the transverse direction and two side edges extending in the longitudinal direction, and comprising a fastening arrangement for fastening the absorbent article, said fastening arrangement comprising a material strip with a longitudinal direction and a transverse direction and with a first short end and a second short end, said first short end of the material strip being firmly anchored in the absorbent article, and the material strip comprising a fastening device.
- Absorbent articles for absorption of body fluids are available in a number of different designs.
- Such diapers can of course be designed as one- piece absorbent briefs which are taken off in the same way as a pair of conventional briefs.
- a design of this kind is, however, best suited for use by persons who are able to stand up and can put the diaper on and take it off themselves.
- Another disadvantage of diaper pants is that they have relatively little capacity for adapting their size.
- the most common type of diaper is what is called an all- in-one diaper, which comprises an absorption body enclosed in an outer cover and which is fastened together at the sides across the child's hips.
- the fastening is usually done with the aid of special fastening devices arranged on securing tabs.
- the fastening devices generally used are pressure- sensitive adhesive, or hook-and-loop devices.
- the securing tabs are in most cases secured on the rear portion of the diaper, at the side edges and near the rear waist edge of the diaper, and are passed forwards across the front portion of the diaper and secured to the latter.
- the diaper is generally provided with some type of receiving surface for the fastening device on the securing tabs.
- some type of reinforcement of the outer cover of the diaper is used, for example in the form of a plastic strip which permits fastening and opening without breaking.
- Securing tabs with hook-and-loop devices are most often provided with the male parts (hook devices) of the hook-and-loop device and are secured to a corresponding female part, which can be a nonwoven surface with fibre loops in which the hooks can be securely hooked.
- the known securing tabs permit a certain adjustment of the fit and size of the diaper, but they are not completely satisfactory in this respect. In particular, both the body shape and girth can vary considerably between different adult users, and the known fastening devices have only a limited capacity for adjustment.
- diapers Another type of diaper which is commonly used on heavily incontinent adults is a diaper supported by a belt.
- Such diapers have a separate or integrated belt which is secured around the user's waist and from which the absorption body of the diaper is suspended.
- a diaper with an integrated belt usually has one half of the belt secured to the rear end of the diaper and protruding from side edges of the diaper. When the diaper is applied, the belt is secured around the user's waist with the diaper hanging down over the user's rear area. Thereafter, the front portion of the diaper is guided forwards between the user's legs and up across the stomach and is finally secured to the belt across the user's stomach.
- the belt is designed to permit fastening across its entire width, it is possible to some extent to adjust the size of the diaper by virtue of the fact that the length or "pelvic dimension" can be varied depending on whether the diaper is secured near the bottom edge or top edge of the belt.
- this possibility of adjustment is very often insufficient, which means that even belt diapers have to be supplied in a number of different sizes.
- a belt diaper can be supported by a separate belt.
- a diaper is preferably applied more or less like a diaper with an integrated belt.
- the diaper is secured with some type of fastening device to a rear part of the belt, after which the belt is fastened round the user's waist. Thereafter, the free end of the diaper is guided forwards and upwards across the user's stomach and is secured to the belt so that the diaper and the belt together assume a shape similar to briefs.
- a belt diaper with separate belt permits a slightly greater degree of size adjustment than a diaper with integrated belt.
- the belt can be designed so that it can be reused. However, these belt diapers too are still not sufficiently variable to satisfy the need for different sizes of diaper for different users.
- an absorbent article of the type discussed in the introduction namely comprising a fastening arrangement for fastening the absorbent article together.
- the fastening arrangement comprises a material strip with a longitudinal direction and a transverse direction, and with a first short end and a second short end, the first short end being firmly anchored in the absorbent article and the material strip comprising a fastening device.
- the fastening arrangement is an extendable fastening arrangement formed by the material strip being folded in a Z along two transversely extending fold lines which divide the material strip into a first end portion at the first short end, a second end portion at the second short end, and a middle portion between the end portions, and the first end portion of the material strip is secured to the middle portion by a first breakable attachment, and the second end portion of the material strip is secured to the middle portion by a second breakable attachment, and the fastening device is arranged on the second end portion of the folded material strip, on a surface directed away from the middle portion.
- a firm anchoring signifies a permanent attachment which is not intended to be broken, either under the effect of the forces which arise during use of the absorbent article or by active pulling apart. A firm anchoring cannot normally be broken without surrounding material being destroyed.
- a fastening arrangement according to the invention can assume two different fastening positions and affords the possibility of choosing between the different fastening positions.
- the fastening arrangement In the first fastening position, the fastening arrangement is used in the folded-together state defined above.
- To obtain the second fastening position it is necessary to break the breakable attachments which fix the Z-folded material strip of the fastening arrangement in the folded state. This has to be done actively by the person fastening the absorbent article round the user's trunk.
- the attachments have been broken, the material strip is unfolded to its full length, which means that the fastening devices have a much greater reach than in the folded-up state of the fastening arrangement.
- the different fastening positions can be used by the carer to adapt the size and fit of the absorbent article individually for each person receiving care.
- the possibility of extending the fastening arrangements means that the width of the diaper can be regulated within a greater interval than was previously possible.
- An absorbent article in the form of a belt diaper instead acquires greater adaptability in the longitudinal direction, as a result of which the diaper can be used for a larger group of users with different pelvis lengths, i.e. different distances between crotch and waist.
- a belt diaper can of course also be adjustable in terms of its waist circumference if the waist band is provided with a Z-folded fastening arrangement in accordance with the invention.
- the absorbent article can advantageously be a belt diaper with an elongate absorption part and a belt which supports the absorption part.
- the absorption part advantageously comprises an absorption body enclosed in a covering, said covering being formed for example by an inner liquid-permeable cover sheet and an outer liquid-impermeable backing sheet.
- the absorption part can be provided with elastic devices along the side edges, by which means elastic leg openings are obtained.
- the absorption part has a first end portion which is firmly anchored in the belt, the first end portion preferably being a rear end portion, and a second end portion, and the extendable fastening arrangement is firmly anchored on the second end portion and is designed to be secured on the belt.
- the extendable fastening arrangement on the absorption part can extend in the transverse direction of the article along a greater or lesser part of an end edge of the absorption part.
- the fastening arrangement can have a greater extent in the transverse direction than in the longitudinal direction. When only one fastening arrangement is used, this is preferably placed at the end edge, centrally on the absorption part.
- At least two Z-folded extendable fastening arrangements are firmly anchored on the second end portion and are designed to be secured on the belt.
- these are preferably placed symmetrically on each side of a longitudinal centre line through the article, in the area between the end edges and side edges of the absorption part.
- the absorption part and the belt are separate parts of the belt diaper which, during use, are fastened together to give a unit which looks like a pair of briefs.
- a belt diaper expediently has one or more extendable, Z-folded fastening arrangements on at least one end edge of the absorption part.
- the belt can be a reusable belt which can be used over again with new absorption parts.
- the belt can be of the disposable type and, like the absorption part, is discarded after use.
- the fastening devices on the fastening arrangement or fastening arrangements at one end edge can be of a type which permits permanent attachment of the fastening devices on the belt.
- fastening arrangement or fastening arrangements on at least one end edge permit release and, if appropriate, reattachment of the fastening devices on the belt.
- Such a design facilitates both adjustment of the fastening of the diaper and removal of the diaper after use.
- the fastening arrangement or fastening arrangements according to the invention can either be arranged on the inside of the absorbent article, which is the side facing towards the user during use, or on the outside of the article.
- the fastening arrangement or fastening arrangements are secured on the inside of the diaper.
- the fastening devices are secured on the inside of the belt.
- Another advantage of arranging the fastening arrangements on the outside of the absorbent article is that there is less risk of chafing or other types of discomfort, because the fastening arrangements are kept at a distance from the user's body. This is a particular advantage when using mechanical fastening devices such as hook-and-loop devices, which can be stiff and hard, with a chafing surface.
- the belt too can be provided with one or more extendable, Z-folded fastening arrangements designed for fastening the belt round a user's waist.
- Such an embodiment means that the width of the diaper can be adapted to the user's girth.
- the article can additionally comprise a further fastening arrangement in the form of a double-folded securing tab which is formed by an elongate material strip having a first end portion which is firmly anchored on the absorbent article, and a second end portion which is folded in against the first end portion and secured to this by a releasable attachment, and a fastening device is arranged on the second end portion, on that surface directed towards the first end portion.
- a securing tab provides for additional fastening, if so desired.
- the securing tab can be left in its folded state and then does not contribute to the fastening of the absorbent article.
- the fastening device is exposed and the securing tab can be used as a complement to the article's other fastening arrangements.
- a securing tab can be used to avoid gaps occurring between a belt and an absorption part.
- the absorbent article is a diaper with two end edges and two side edges and having two end portions and an intermediate crotch portion, and with an extendable fastening arrangement firmly anchored to each side edge on the one end portion, the fastening arrangements being designed to cooperate with a receiving device on the second end portion.
- the breakable attachments on the Z-folded, extendable fastening arrangement according to the invention, or on the double-folded securing tab can comprise breakable welds. It is further possible to produce breakable attachments in the form of breakable adhesive seams.
- a suitable adhesive for producing such seams is a dry structural adhesive which is not tacky after breaking the seam.
- Dispomelt® 2000 One example of such an adhesive is Dispomelt® 2000.
- the breakable seams must have sufficient strength to be able to hold the Z- folded fastening arrangement together in the folded state when the carer chooses not to unfold the fastening arrangement. At the same time, the seams must be able to be broken easily by manual force if the full length of the fastening arrangements is to be used.
- the person skilled in the art will, given his knowledge of the adhesive strength of different adhesives and the tensile and shearing forces which occur during use of a diaper, have no difficulty in producing seams with the correctly adapted seam strength.
- hook-and-loop devices we mean all types of fastening devices in which a male part provided with hooks or projections cooperates with and catches in a female part which is provided with eyelets or fibre loops.
- the male part is preferably arranged on the Z-folded extendable fastening arrangement and is designed to cooperate with a receiving surface constituting the female part of the hook- and-loop device.
- the folded material strip in the fastening arrangement according to the invention preferably consists of a flexible material with high tensile strength.
- Suitable materials are plastic film, nonwovens and various types of laminates of these materials.
- the material in the material strip has a soft surface on the side facing towards the user.
- the material may be expedient for the material to be breathable, i.e. allow moisture and water vapour to pass through.
- Nonwoven materials generally have a soft surface, let moisture pass through and do not stick to the skin.
- the material strip is easily pliable and has soft edges, so that there is minimal risk of chafing of the user's skin.
- the material of the material strip can be substantially inelastic so that it does not stretch during use. Alternatively, the material can be stretchable and is then preferably elastically stretchable. Such an embodiment affords the possibility of continuous adjustment of the length of the material strip during use of the absorbent article.
- the fastening arrangement can be provided with a grip tab at the second short end of the material strip.
- a grip tab can expediently be formed by an edge area of the material strip which is free from bindings.
- the fastening arrangement can be secured to a cover sheet of the absorbent article in such a way that the fastening arrangement, in its folded state, is accommodated completely within the surface of the cover sheet.
- the fastening arrangement can be firmly anchored at an edge of the absorbent article, so that the fastening arrangement protrudes outside the edge of the article even in the folded state.
- the fastening arrangement can be firmly anchored on a cover sheet of the article, or between the cover sheets.
- the fastening arrangement can of course be firmly anchored in some component located between the cover sheets. Attachment is expediently made by adhesive bonding, welding or sewing.

- Figure 6 shows an all-in-one diaper according to the invention.
- FIGS 1 and 2 show a diaper 100 with a substantially rectangular planar shape.
- the diaper 100 is shown from the side which is intended to face towards the user during use.
- the diaper comprises in a conventional manner a liquid-permeable covering sheet 101 , a liquid-impermeable covering sheet 102, and an absorption body 103 enclosed between the covering sheets 101,
- the liquid-permeable covering sheet 101 has the same shape as the absorption body 103.
- the liquid-impermeable covering sheet 102 is also shaped like the absorption body.
- the covering sheets 101 , 102 have a slightly greater planar extent than the absorption body 103 and form a connecting edge 104 which protrudes around the periphery of the absorption body 103.
- the covering sheets 101 , 102 are connected to one another around the absorption body, for example by adhesive, sewing, or welding by heat or ultrasound. Moreover, one or both of the covering sheets 101, 102 can be connected to the absorption body 103, for example by adhesive, needling, sewing, or by welding with heat or ultrasound.
- the liquid-permeable cover sheet 101 is of a conventional type and can thus consist of any liquid-permeable material suitable for the purpose. Examples of such materials are various types of thin nonwoven material, perforated plastic films, mesh material, liquid-permeable foam material, or similar.
- the liquid-permeable cover sheet 101 can be made up of two or more different materials in order to permit different functions of the cover sheet. For example, it is customary to arrange a liquid-transporting layer inside a liquid admission layer. It is also known to arrange different types of materials on different parts of the surface of the diaper facing towards the user during use.
- a material with a good admission capacity can advantageously be arranged at the portion of the diaper which is expected to be wetted first by most of the body fluid, while portions of the covering sheet located at a distance from the first wetted area can be designed with a barrier function in order to prevent absorbed liquid from leaking out of the diaper.
- the liquid-permeable cover sheet 101 is a separate sheet of material, and instead the cover sheet 101 can be a surface of the absorption body 103 of the diaper 100.
- the liquid-impermeable covering sheet 102 can also be made of any available suitable material. Especially advantageous materials are thin plastic films, liquid-impermeable nonwoven material, or layered material which has been coated with liquid-impermeable material such as wax, resin, adhesive or the like. It is also possible to use liquid-impermeable material laminates. For example, it may be desirable to provide the reverse of the diaper with an outer sheet of textile character, for example a nonwoven sheet.
- Such a nonwoven material provides a soft, skin-friendly textile surface and affords advantages such as a high level of user comfort, a high degree of friction and, consequently, a better hold on the clothing worn over the diaper.
- a textile surface is often considered to have an aesthetically pleasing appearance. It is also an advantage if the liquid-impermeable covering sheet 102 is breathable, i.e. lets gas and water vapour pass through the sheet.
- the absorption body 103 can also be designed in a conventional manner and with conventional materials. Suitable absorbent materials for use in the absorption body 103 are, for example, cellulose fluff pulp, absorbent bound fibre sheets, tissue layers, absorbent foam, peat or the like.
- the absorption body 103 can also advantageously contain superabsorbent polymers, i.e. polymers which are able to absorb many times their own weight of liquid and form a liquid-containing gel.
- Superabsorbents are generally present in the form of particles, flakes, fibres, granules or the like.
- the superabsorbent material can be present alone or in combination with other absorbent material and applied as layers, or in the form of a mixture with other materials such as cellulose fibres or synthetic fibres.
- the diaper 100 in Figures 1 and 2 is substantially rectangular in shape and has two straight side edges 105, 106 and two similarly straight end edges 107, 108.
- the diaper can be divided into a front portion 109, a rear portion 110, and an intermediate crotch portion 111.
- Elastic devices 112, 113 are arranged along the side edges 105, 106 and form leg elastics when the diaper 100 is in use. Suitable elastic devices are various types of elastic threads, bands, elastic nonwovens, elastic foam material, or similar.
- the diaper 100 is further provided with a two-part waist belt 114a,b which is arranged with a belt half 114a,b protruding at right angles from each side edge 105, 106 at the rear end edge 108 of the diaper.
- the belt halves 114a,b consist of strips of a soft and flexible material. Suitable materials are nonwoven materials or material laminates of one or more layers of nonwoven, plastic film or the like.
- the belt halves 114a,b can comprise material layers whose main purpose is to give the waist belt some desired property, such as improved softness and comfort, increased tensile strength, a more aesthetically pleasing appearance, a certain elasticity, a certain absorption capacity, etc.
- the waist belt 114a,b is additionally provided with loop devices 115 arranged on the outside of the waist belt, i.e. on the surface facing away from the user during use. In Figure 1, the outside is directed away from the observer.
- Such loop devices 115 can be formed in a woven, knitted or cast material or can consist of fibre loops in a nonwoven material. As in the example shown, the loop devices 115 can be arranged across the whole outside of the waist belt 114a,b or can be placed only in special fastening areas intended for fastening to corresponding hook devices.
- the diaper is additionally provided with fastening devices 116, 117, 118 which have hook devices 119.
- a fastening device 116 provided with hooks is arranged at the free end 120 of one belt half 114a, on the surface directed away from the loop device 115.
- Fastening arrangements 117, 118 are also arranged at the corners between the side edges 105, 106 and the front end edge 107.
