SE512650C2 - Absorbent pants with improved positioning - Google Patents

Abstract

Absorbent pants are provided comprising a pants layer intended to face the body of the user in use and an outer barrier layer which is liq. proof and arranged outside the pants layer relative to the body of the user. The pants layer has a surface area greater than that of the outer barrier layer and is joined in parts to itself, directly or via a joining mechanism, so that in use it alone constitutes the waist opening, leg openings and load bearing regions in contact with the user's body.

Description

512 650 z because it is only a relatively narrow line of contact which is to prevent the liquid which is not immediately absorbed by the absorbent body from flowing over the edge of the diaper. The pressure on this narrow line can become quite large and the liquid does not have a long distance to fi to cross the contact line, as soon as the contact is no longer sufficient to resist leakage. In addition, a large tension of the elastic bands is required to ensure that the leg waistband does not release contact with the user's skin. This in turn can lead to problems, namely skin abrasions. Even if the waistband were able to withstand the pressure of the liquid and not let it pass, the liquid will instead be applied to the top of the absorbent body and thereby keep the skin moist, which in itself can lead to skin irritations.

In order to increase safety against leakage, especially of loose faeces, past the sides' nappies or leg straps, fl era of today's nappies have been fitted with raised barriers fl inside the elastic leg straps. An example of such a diaper is shown in the patent EP 0 219 326. This patent aims, among other things, to provide a diaper with double leakage protection and to create a channel with the aid of the remaining barrier, which could keep running fluids in the diaper. . The barrier reser iken rises up, among other things, along the inner part of the user's thigh in the crotch portion. Body fluid that is not immediately absorbed by the absorbent body in the diaper, eg loose feces, is stopped by the barrier och iken and collects in the said channel. If the body fluid were to still flow past the barrier fl iken, it is claimed that the leg waistband will form an additional banner against leakage. Although the diaper according to EP 0 219 326 is equipped with an additional barrier within the prior art, it suffers from the same disadvantages as the latter, exhibiting only a normal lining against the user's skin. This narrow contact feature allows the contact with the user's skin to be released when the banner is subjected to a large pressure of, for example, a larger amount of urine. It is also apparently no stranger to the idea that the banner ike would not be sufficiently resistant to prevent liquid fl over the barrier, since the elastic leg waistband outside the banner fl has been protected. In addition, as with the known elastic leg waistband, a large area (albeit a smaller area than before) of the user's skin is still exposed to exposure to the liquid or feces collected in the so-called the channel between the barrier and the absorbent body, ie the risk of skin initiations is obvious. This barrier construction is therefore far from perfect.

It should be noted that it is also fi NNS diapers on the market like the diaper beskrima patent, provided with similar läckagebaniärer also at the diapers waist opening llllnliilillllllillll llllllllllllilllll al ll al illiillllliill fi llarállliwlllii | ilililiil% .lllllllllill fi llliwlillilillllill lll l ll lll .l l Category "llllüllll 'hlllllllili | L || illlllll fi lllilllrlilllllll .

Recently, a new type of diaper has been developed and launched on the market, the so-called the pant diapers. These differ from the traditional nappies, especially with regard to fastening systems, ie the system that ensures that the trouser nappy or the regular or "open" nappy can be put in place on the user. Open diapers are closed to a trousers on the user by means of fastening means of various kinds, such as adhesive tape strips, velcro or snaps. Trouser diapers, on the other hand, are already sealed by the manufacturer in the side sections so that a pair of trousers has been obtained, showing a waist opening and two leg openings. The closure to a side seam in the respective side pan can be done in your own way, for example by means of an adhesive joint or a weld joint.

The trouser cover of the trouser diapers is also included in the pant diaper fastening system. By this is meant the cover which, through its elastic ability to hold, ensures that the trouser diaper slips around the body of the user and prevents the trouser diaper from hitting the user. Of course, there may be other factors that affect the ability of the pant diaper to remain in the intended place on the user. The difference between pant diapers and open diapers lies in the fact that the latter can be tightened around the waist of the user by means of the fastening means, in the same way as you can tighten the waist belt on a pair of long trousers. Trouser diapers, on the other hand, are not provided with such tight-fitting fastening means, but must normally rely on their elastically tightening casing.

There are known trouser diapers, for example the one described in EP 0 320 991. This trouser diaper has a central absorption unit and two elastic side panels which are connected to the side edges of the absorption unit. Together they form a waist opening and two leg openings. The trouser diaper is, in a manner known for open diapers, also provided with elastic members along the edges of the leg openings and the waist opening. The absorption unit comprises an absorbent body between a liquid-permeable inner casing layer and a liquid-impermeable outer casing layer. The space between the inner cover layer and the user's skin will be very limited, so that the faeces deposited on the inner cover layer will be able to be in contact with the user's skin and smear it down.

The inner lining layer will also be wetted by the user's excreted urine.

It is of course not desirable for the user's skin to be in contact with a moist casing layer, as is the case in those parts of the inner casing layer which at least occasionally come into contact with the user's skin. B) From 512 650 4 Characteristic of known pant diapers (and also of known open diapers) is that it is the outer casing layer, i.e. that which is arranged outside the absorbent body, which forms the supporting casing layer of the trousers. This layer refers to the cover that you get if you peel off all the layers and elements included in the pants that do not actively contribute to the pants becoming a pants, ie form a waist opening and two leg openings and without which the pants could no longer hang together around the body of a user. Particularly important supporting parts are the so-called side seams, ie the parts of the trousers in which parts of the front and back part of the trouser-forming layer have been connected to form the waist opening and the leg openings.

The supporting trouser-forming casing layer for the known trouser diaper according to EP 0 320 991, consists of the two elastic side panels and the outer casing layer arranged outside the absorbent body. In this case, the load-bearing trouser-forming cover layer thus consists of fl your spliced material pieces. When the absorption lid is filled with urine, its increased weight will cause the outer casing layer placed outside the absorbent body to be subjected to a force of gravity, which in turn is transmitted to the elastic side panels and the inner casing layer to which the outer casing layer is connected. This leads to the elastic side panels being stretched and to the distance between the user and the inner cover layer increasing and to any leakage banners making it more difficult to keep in contact with the user's skin. In other words, the risk of leakage increases.

A scarred example of a trouser diaper in which the outer casing layer forms the supporting trouser-forming layer is WO 88/07337. The outer cover layer in this case is elastic. The absorbent body is arranged inside the elastic pant-forming cover layer, towards the user's body.

In an attempt to improve the holding and seating properties of pant diapers, it has been proposed in WO 93/17648 to provide a pant diaper with elastically stretchable areas in the front and / or back portions of the pant diaper, while the crotch portion is relatively unstretchable. However, this trouser diaper is still traditionally constructed, in that the outer casing of the trouser diaper constitutes the trouser-forming layer of the trouser diaper and that the absorbent body is thus arranged inside this trouser-forming layer.

It has further been proposed to provide open diaper cover layers facing the user with one or two openings for the passage of urine and / or feces down into a kind of pockets with the absorbent body as the bottom of the pocket, in order in this way to isolate Il 'Him M || in n i rm w m i »|| rlrti Iltllllll IWlIlIH rnmnnw utnfi J fl tiwir 10 15 512 650 p. clay the user's skin from contact with especially feces. U.S. Pat. No. 4,662,877 discloses such a diaper which comprises an upper layer facing the user's body, in which it is provided with an elongate opening. Along the edges of the opening elastic bands are arranged in order to force the edges of the opening up from the underlying absorption body. Other elastic arrangements are also conceivable according to this patent.

EP 0 359 410 discloses a similar diaper having a body-sweating elastic cover layer provided with an opening. An empty space is created between the cover layer and the absorption channel.

In analogy with the pant diapers above, it is found that even if the diaper layer facing the user facing the wearer has been removed more than has been the case for previously known diaper liquid-sweating cover layers, it is still the diaper outer cover layer, i.e. the layer applied outside the absorbent cart seen from the user. , which is the layer that supports the diaper when using the same, ie after the diaper has been taped together with the fastening tapes on the user. The bearing outer casing sight will also be located at a distance from the user's body, which leads to a greater uncertainty regarding the position of any leakage banners in relation to or contact with the user's genitals or anus.

Finally, it is also known from US 4,756,709 to arrange elastic zones with different elastic directions of force in a trouser-forming outer casing. In the rear and front rim portions of the housing, the housing is extensible in the transverse direction and in an intermediate crotch portion it is extensible in the longitudinal direction. However, this trouser-forming casing layer, like the others listed above, is located outside the absorbent body.

Purpose and main features of the invention An object of the present invention is to solve the problem that dispensed liquid which is not immediately absorbed by the absorbent body is likely to leak over any edge of the article.

Another object of the present invention is to prevent or at least make it difficult for the faeces and urine absorbed in the trousers to come into contact with the user's skin. A further object of the present invention is to solve the problem of ensuring that excreted urine and faeces are collected directly in the designated collection areas in the trousers. Yet another object of the present invention is to solve the problem of preventing the casing layer facing the user's body from being brought out of position relative to the user.

This is achieved by an absorbent trousers having a waist opening and two leg openings, which trousers comprise a trouser layer, which in the use of the trousers is intended to face the user's body and an outer barrier layer, which is made of a liquid-tight material and placed outside the trouser layer seen in direction from the user's body in the use of the trousers, and absorbent material, for example placed in at least one absorbent body, arranged between the trouser layer and the outer barrier layer, the trouser layer being larger than the outer barrier layer, the trouser layer being joined in portions by itself or comprising means for to be able to be joined together in portions with itself, so that when using the trousers alone constitutes the waist opening and leg openings of the trousers, that the bearing parts of the trousers and all parts abutting the user's body are thereby built up of the trouser layer alone, the trouser layer has at least one opening for passage of urine and / or electricity faeces, the outer barrier layer being arranged at a height with the opening or openings, the trouser layer being hydrophobic and the outer barrier layer being continuously connected in connecting areas with the trouser layer around the opening or openings.

The term inner trousers, used in several of the following claims, refers to the same thing as the term trouser layer, which has been used in the description and other patent claims.

By the term absorption unit is meant a unit which is intended to absorb and retain urine and / or faeces or, where applicable, menstrual fluid.

By reversing the habitual thinking that the supporting trouser-forming casing layer should always be applied at the far end from the user's point of view and also the layer llll IIIII fl lilllilllll Hlll | l il lnlnl AJ 'how 10 l \.) UI b) Lll 512 650 7 which is arranged outside the absorbent body, an absorbent trousers have now been provided which snug tightly against the body of the user and in which the outer cover layer or the barrier layer and the absorbent material are released from the influence of forces from the trouser layer. In previous diapers and trouser nappies, the outer cover layer has been allowed to absorb most of the lafter which acts to hold the trousers in place around the waist of the user. In an effort to achieve contact between the leak-sealing outer barrier layer, various barriers have been built up from this outer layer, which at best have been able to achieve one or fl your narrow lines of contact with the user.

The present invention instead has a completely inverted construction. Instead, it is the cover layer facing the user's body that forms the trousers and which absorbs all the forces that act to hold the trousers in place around the waist of the user. The absorbent material contained in the trousers, for example placed in an absorbent body, and the outer barrier layer, are connected from all trousers-forming and supporting portions of the trousers and instead form an appendage on the outside of the trousers-forming body-bearing layer. The trouser-forming trouser layer can be compared to a second skin that has been pulled over the user's skin. The outer barrier plate can be likened to a collecting container, a bag or a bag, which is attached to the "other skin". This collection container does not in itself contribute to the formation of the trousers themselves.

The absorbent spoon, if any, is preferably arranged in this collecting container or not.

In an advantageous embodiment of the invention, an elastic member is biased in the transverse direction in the front and the rear waist portion of the trouser layer and biased in the longitudinal direction in the crotch portion of the trouser layer, the front and rear waist portions respectively having substantially the same elastic forces. in the circumferential direction of the trousers of the trousers and the crotch pait exhibit elastic forces acting mainly in the circumferential direction of the leg openings of the trousers.

In a further advantageous embodiment of the invention, the outer barrier layer has end and side edges, the side edges of which are connected to the trouser sleeve within areas between the respective side seam and the intended longitudinal line of symmetry so that the outer barrier layer is substantially unloaded by traction shafts. against the longitudinal line of symmetry one between these connecting areas and between the end edges of the outer barrier layer connecting orthoses with trouser layer IEI. In a further particularly advantageous embodiment of the invention, the trouser layer has at least one opening arranged within a front region of the crotch portion seen in the direction of the front iride portion, and at least one opening arranged within a rear region of the crotch portion, seen in direction towards the posterior ridge portion, intended for the passage of urine and faeces through the trouser layer to a front and a rear pocket between the trouser layer and the outer barrier layer, respectively, which are separated from each other so that transport of urine and faeces is prevented between.

Thanks to the fact that the trouser layer according to the invention is snugly fitted along the body of the user, it is now possible to safely place the opening or openings in the areas of the trouser layer which are intended to abut the intended user of the trousers genitals and anus, assured that the opening or openings when using the trousers, do not move so that the opening or openings end up in the wrong place. This also means that the openings do not have to be made larger than necessary, whereby it is not necessary to expose a larger area of the user's genitals, anus or surrounding skin areas, than necessary. This helps to keep the user's skin as clean and dry as possible. In addition, since the accuracy is increased, ie the certainty that urine or faeces hit the opening or the respective opening, the trouser layer will be kept very dry and thus the user's skin will also be able to be kept drier than with previously known diapers and trouser nappies.

Another advantage of being able to store faeces well enclosed in a box is that faeces, especially hard faeces, cannot be spilled on, for example, the changing table when changing a trouser diaper. Especially for previously known elastic pant diapers, it has been found to be a problem that the pant diaper, when tearing up the first of the two side seams, quickly contracts. If the pant diaper contains hard stools lying loosely on the inner cover layer, there is a great risk that the stools will spill out and grind on the changing table or other surface next to the place where the change takes place. According to the present advantageous embodiment of the invention, the feces will be well enclosed in their pocket lll llllll. . ~ l - ll llllll llllll llllll llll lllllll llllll llllll ll ll ||| l l llll lllll l 'II l llll lll Illll llllll lllllll WII rl | l lllll rlllll l || ill illll lllil "t ...

Additional advantages and features of the invention will be apparent from the following patent claims and the following description of exemplary embodiments.

Description of exemplary embodiments In the description of the various exemplary embodiments, the same numerals will be assigned to such details and structural elements as are common to the exemplary embodiments in the various figures. Figure 1 shows an absorbent trousers 1 according to the invention, which it is intended to be used on a user. The user is schematically indicated in Figure 1 in the form of severed waist and leg panels. The trousers have a waist opening 2 and two leg openings 3 and 4, of which, however, one of these is obscured in figure 1.

The trousers comprise a trouser layer 5, an outer barrier layer 6 and an absorbent body 7 arranged between them. Ll ll lllllll ll lll ll - ... na fl iilinririm i ii, _ 10 20 25 512 650 The trouser layer 5 is facing the user's body and abuts against this over substantially its entire surface, which is best shown in fi gur 3. In this fi gur, for the sake of illustration, the absorbent body and the outer barrier have been removed. It can be seen that the trouser layer 5 slips close to the user's laop. Figure 3 also shows that the trouser leg 5 forms a trouser configuration which in itself forms the waist opening 2 of the trousers and leg openings 3 and 4. No additional layers or pieces are necessary for a self-supporting trousers to be obtained.

The trouser layer 5 is joined in its side portions by two side seams, one on each side, of which only one 8 is visible in Figures 1 and 3. The side seams extend from the lower opening 2 to the respective leg opening 3,4. The side seams can, for example, consist of a continuous or discontinuous adhesive joint or weld joint. The latter can be achieved, for example, by means of ultrasonic welding. However, it is not necessary for the side seam to consist of a joint of this kind assembled by the diaper manufacturer. The side portions of the trouser layer may instead be provided with fastening means, which are either openable and resealable or which are intended to be interconnected from the user in a detached position in a manner predetermined by the diaper manufacturer, so that a trousers is formed. Such trousers resemble and behave during use in essentially the same way as trousers which have side seams of adhesive or welded joints. Examples of absorbent trousers with such alternative side seams are shown in our Swedish patent applications SE 9401224-2, SE 9401225-9, SE 9401226-7, SE 9401227-5, and SE 9401228-3.

Referring to Figure 7, there is shown an example of a trouser cover 5 as it may look before it is assembled into a trouser configuration as in Figure 1. The trouser layer 5 includes a front and a rear waist portion 9 and 10. These waist portions 9, 10 together enclose the user's abdomen and back end portion, respectively, see Figures 1 and 3. The trouser layer 5 also comprises a crotch portion 11 between the two waist portions 9,10. The crotch portion is placed between the user's legs when using the trousers.

However, there are no definite limits for the transition from one of the ridge portions 9.1O to the branch portion 11. The waist portions 9,10 do not have to have the same width, but can be different widths, for example the rear ridge portion may be wider than the front one.

The two waist panels 9,10 each have an end edge 12 and 13, respectively, and two side edges 14,15 and 16,17, respectively. The crotch portion has two side edges 18,19.

The same side of an imaginary longitudinal line of symmetry drawn from the end edge 12 of the front rim portion 9 to the end edge 13 of the rear waist portion 10, respectively, is the same side of an imaginary longitudinal line drawn from the end edge 12 of the front rim portion 10, - - bonded together to form side seams, of which, as mentioned above, only one side seam 8 (connecting the side edges 15,17) is shown in Figures 1 and 3. The side seam 8 in Figures 1 and 3 are shown only schematically. The Navy knows that there are ways to connect the side edges 14.16 and 15.17 respectively to each other. For example, the side edges can be folded over or they can be connected to the same side of the trouser layer facing each other. In the latter case, the side seam can be turned either out of the user or in towards the user.

The trouser layer 5 is elastic. Referring to Figures 1, 6 and 7, there is shown an example of an elastic pant layer which includes an elastic member 20 and at least one substantially inelastic material layer 21. The elastic member 20 is biased to the substantially inelastic material layer 21.

The elastic member 20 in Figure 6 is shown as an elastic net, but also an elastic band, an elastic fabric (nonwoven) or elastic bands, ribbons or the like can be used, the latter in which case being laid over a large part. of the surface of the material layer so that together they are considered as a single elastic member.

The elastic member should exhibit an elasticity to such an extent that it can be extended to an elongation of at least 25% of its unstretched, relaxed length, i.e. to a length which is at least 1.25 times its unstretched length and then at the relief from the stretching daft , be able to return at least to a maximum extension of 15% of its original unstretched length. Ideally, the elastic member should be able to extend much longer than 25% of its relaxed length and be able to return to its original relaxed length or next to it. This does not exclude that an elastic material which exhibits a fl surface limit at which its elongation and contraction properties change can be used, as long as it still exhibits elastic properties above its fl surface limit.

The elastic member 20 is elastic longitudinally and transversely, or can be oriented both longitudinally and transversely, in the case of a wire or band-shaped element. The requirement for elasticity can be placed on both the longitudinal and transverse abutment of the elastic member.

Examples of preferred elastic members 20 are elastic meshes, which comprise components of tennoplastic A-B-A block copolymers. The end block A may be in relatively rigid polymers, such as polystyrene or a polystyrene homologue. The middle block B may be a soft flexible polymer chain, such as polybutadiene, polyisoprene or poly (ethylene-co-butene). These copolymers are often called SBS and SIS respectively and are commercially available under the trademark Kraton G and SEBS, respectively, which are commercially available under the trademark Kraton D.

To improve the processability of these materials, they are often blended with one or more polyols, for example polyethylene, polypropylene, polybutene, ethylene copolymers, propylene copolymers or butene copolymers.

The substantially inelastic material layer 21 may consist of a nonwoven fabric, for example of the meltblown, spunbond or thermobond type, for example comprising polypropylene fibers. Thermoplastics can also be used.

The substantially inelastic material layer should suitably be air and vapor permeable, as it must be in contact with the user's skin and therefore must not be so tight that the skin cannot breathe. By substantially inelastic is meant in this context that the elasticity of the material layer is substantially less than the elasticity defined above for the elastic member 20. The material layer 21 may also consist of fl your spliced pieces of material which in this case together form the material layer 21 shown in fi gures 6 and 7. In this context, it is worth noting that the shape of the trouser layer is not limited to that shown in fi gurema (an hourglass shape), but can be done differently if appropriate, for example to dimension the trousers to a different user size. The trouser layer 5 shown in fi gurema is suitable for children of "size", ie with weight, 10-15 kg.

Sizes for both larger and smaller children are of course also conceivable, as well as sizes adapted for incontinent adult users.

In order to obtain preferred elastic force directions in the trousers 1 and at the same time give the trouser layer 5 a trouser-like shape, the elastic net 20 is biased in the transverse direction in the front and the rear waist portion 9 and 10, respectively, of the trouser leg 5 and biased in the longitudinal portion the trouser layer 5. In order to provide curved portions of the elastic net 20 which well follow the contours of the side edges 18,19, some of the threads in the elastic net have been cut, cut or otherwise broken. Thereby larger meshes 22,23 are obtained in the net in a front 24 and a rear part 25 of the crotch portion 11. It is pointed out that even before the interruption of certain threads in the elastic net 20, curved portions of the elastic net 20 had been obtained within the branch portion of the trouser layer 11.

The curvature is caused by the cooperating transverse and longitudinal forces obtained when the net is tensioned in the above-mentioned manner. However, it is preferred to configure the net, for example in the manner shown in Figure 6, in order to better adapt the elastic tensile forces to the side contours of the trouser layer. It is of course conceivable to create larger meshes within fl era or other areas of the elastic mesh than shown in Figure 6. For a more detailed description of how to stretch and configure elastic materials such as elastic meshes for elasticizing trouser layers, please refer to our Swedish patent application with application number SE 95003 87-7.

Elastic films and nonwovens can be stretched and configured in substantially the same manner as the elastic mesh of Figure 6. In order to make portions of them better follow the side edges of the crotch portion, holes or slits may be taken up in suitable places, for example in corresponding places as the large meshes 22,23 in the net of Figure 6.

Elastic threads, ribbons or the like may be applied in a different way, which is described in more detail in our Swedish patent application with application nuiruner SE 95003 84-4. In this case, the laying pattern of the elastic threads must be adapted to the contour of the side edges of the crotch portion. Elastic nets, films and nonwovens, on the other hand, have, compared to threads, a surface with a spread which is relatively large in two directions perpendicular to each other and the adaptation to the contours of the side layers of the trouser layer can be done by the above-mentioned reconfiguration technique. elastic mesh or slitting of the elastic film or nonwoven fabric.

In a possible manufacture of the trouser layer 5, the material layer 21 can be cut out of a running web of material, from which segments are periodically cut from each edge of the web, to create the curved side edges 18,19 in what forms the crotch portion 1 1 of the trouser layer, when individual material layers 21 are cut. off from the track. For example, the elastic member 20 may be applied over the continuous web after the periodically repeated curved side edges have been cut out, but it may instead be applied over the continuous web before the periodically repeated curved side edges have been cut out. In order to adapt the trouser layer 5 to a certain shape and size, alternatively a certain part of the trouser layer can be removed, for instance in connection with cutting the leg openings. This means that even a portion of the elastic member 20 can be removed in connection with this operation. In other words, the elastic member 20 does not always have to be arranged inside the side edges of the material layer .liiliiiiiiiiliiliiliiliii iiliiiiiiiii iii. | I iiiiiiiii.i ..._..-..-. iiiii iiiliiiiiiiiliiliii i l | iiili-iilillililiilil i ii lilil lill lillllillililiili ll lll lll llllllllllllllll l ||| l l || l |||| ll | l | l | l ||| l ||| llll || liii iii | L | iiiiii iii iiiiiiiiiiiiiiiiiiiiiiiiiiiiiii iiiiiiiiiiiiiiiiiii iiii ii iii iii iiiiiiiii iiiiiii IIIIIIIIIIIIIIII iiiiiiiiiiii iiiiiiiii iiiiii iiiiiiiiiiiiiiiiiiiiii 10 20512650 15 14-19, for example in grenpaniet 11, as shown in Figure 6, before the leg openings are cut.

In order to finally complete the trouser layer 5 as shown in Fig. 6, respectively in assembled condition when used in Fig. 1, the trouser layer 5 further comprises a substantially inelastic material layer 21. Thus, the elastic net 20 is pre-tensioned between two substantially inelastic material layers 21. see 7 gur 7.

These can preferably be of the same type to facilitate the connection between them, for example in ultrasonic welding, but it is of course also possible that they can be of different types. The connection can also be effected by other means, for example glue. It will be appreciated that the second layer of material is suitably cut in the same manner as the first, preferably at the same time, after the two layers of material have run together, with the elastic member between them.

Because the material layers 21 are inelastic and cannot be appreciably stretched in any direction, the connection of the elastic net 20 between the inelastic material layers 21 has locked the directions and the magnitude that the elastic member 20 can extend out of the trouser layer. 5. The elastic net 20 is preferably not directly connected to either of the material layers, but is instead indirectly fixed by the material layers 21 being connected to each other in areas within one of the meshes of the net. As a result, the net 20 is locked between the material layers 21.

Thus, the inner and rear waist portions 9 and 10, respectively, will exhibit elastic forces acting mainly in the circumferential direction of the waist opening of the trousers 2 (see Figure 1) and the crotch portion 11 will have elastic forces acting mainly in the circumferential force of the trouser leg openings 3,4. The waist portions of the trousers 9,10 perpendicular to the circumference of the trousers 'circumferential opening 2, which are important for the trousers' function, will thus not occur. Another reason for locking the elastic member's extent to the extent is that it should not be overloaded. At the maximum elongated length determined during application to the inelastic material layers, the laafter of the trouser layer will continue to be taken up by the inelastic material layers, which are relatively unstretchable and stop further elongation of the elastic organ.

It is not necessary for the trouser layer to consist of a larnate comprising two substantially inelastic and unstretchable layers of material with an intermediate elastic member. The material layers can in turn comprise än more than one layer and it is also conceivable to omit one material layer altogether. In the latter case, the elastic member may be attached to one side of the remaining single layer of material. This can be done, for example, through the method shown in our Swedish application SE 9304232-3. The method is characterized in that the elastic material, for example an elastic net or an elastic thread, comprises at least one elastic component and at least one thermoplastic component and that only the thermoplastic component, or components, are connected to the material layer. For further details, please refer to the said application.

The absorbent trousers 1 in Figure 1 also comprise an outer barrier layer 6. The outer barrier layer 6 may, for example, consist of a liquid-permeable belt, for example a polyethylene belt, or of a nonwoven fabric made liquid-permeable or of an extrus laminate or of an extrusion laminate liquid permeable m lm and an ñbert fabric. In the latter examples, the nonwoven fabric is suitably arranged at the end of the trouser layer 5, in order to give the trousers a soft and less plastic appearance, and an outer layer which is at the same time comfortable to wear. The outer barrier layer may furthermore be of a stretchable material.

In Figure 8 (showing the opposite side of the trouser layer 5 in Figure 7), the trouser layer 5 is shown in a flat and non-assembled condition with the outer barrier layer 6 applied to the trouser layer 5. The trouser layer 5 is biased with the outer barrier layer 6. The outer barrier layer 6 has end and side edges 26.27 and 28.29, respectively. The end edges 26,27 are connected to the trouser layer 5 in portions 32,33 thereof which extend from the respective end edges 12,13 of the trouser layer and a short distance inwards towards the crotch portion 1 1. The side edges 28, 29 are connected to the trouser layer 5 within areas 30,31 between the respective side seams, 14-17 which [assembled condition forms the respective side seam 8, see figure 1, and the imaginary longitudinal line of symmetry. As a result, the outer barrier layer 6 will be substantially unloaded by tensile forces in the trouser layer 5, which are perpendicular to the longitudinal line of symmetry within an area delimited by the connecting areas 30-33 between the end and side edges 26-29 of the outer barrier layer 6 with the trouser layer 5. In this way, the trouser layer 5 will be able to be pulled together at night without being affected by forces from the outer barrier layer 6 and will thereby be able to abut against the body over substantially its entire surface without any gaps having to occur between the trouser layer 5 and the user's body. The outer barrier layer 6 has in this way been released from the load-bearing inner layer of the trousers, ie the trouser layer 5, and all transverse forces, ie lll lllll lllll lll lll lll lll lllll lllll lllll lllll lllll lllll lllll lll-r lll 10 15 20 25 35 512 650 17 forces in the circumferential direction of the inner opening 2 (see figure 1), will essentially be absorbed by the trouser layer 5 alone.

With reference to Figures 3-7, an advantageous embodiment will now be described.

The trouser layer 5 is provided with one or two openings for the passage of urine and / or faeces. The openings are shown in the figures as holes, but other types of openings which allow the passage of urine and faeces are of course conceivable, for example slits or perforated parts of the trouser layer, ie parts having a large number of very small holes. The latter variant, however, is less obligatory for the passage of faeces, but is best suited for the passage of urine. In Figure 6 it has previously been shown that large meshes 22,23 can be provided in the elastic net 20 in order to adapt it to the contour of the side edges-lis 19 of the trouser layer 19 in the crotch portion 11.

In the finished trouser layer 5 shown in figure 7, two openings 34,35 are accommodated which in position correspond to the position of the large meshes 22,23 in figure 6.

The meshes 22,23 thus have a double role to play. In addition to contributing to the placement and direction of the elastic threads in the mesh 20, they can be used as suitable areas of the trouser layer 5 to receive the openings 34,35 which are to allow the passage of urine and faeces, respectively. The smaller opening 34 is hexagonal and arranged in the front part 24 of the crotch portion I 1. The slightly larger opening 35 is triangular and arranged in the rear part 25 of the crotch portion 11.

Instead of receiving larger meshes in advance in the elastic mesh which in their position correspond to the areas of the trouser layer within which openings are to be taken up, the larger meshes can of course be taken up at the same time as the opening mesh after the elastic mesh has been connected to the inelastic material layer. , ie the openings are received in the finished trouser shield which comprises material layers on one or both sides of the elastic net.

The size and location of the two openings, shown in Figure 7, can of course be varied taking into account the size and anatomy of the user category for which the trousers, in which the trouser layer is included, are intended to fit.

Figures 4 and 5 show two different variants of openings in the trouser layer 5. The trousers are just as in figure 3, shown with the outer barrier layer and the absorbent body removed. The trousers are shown from below, ie the spectator looks at the trousers in the direction from the user's feet and up towards the user's crotch. The trousers are further shown pulled on a transparent doll that simulates how the trousers are meant to sit on a living user. The decapitated legs of the doll are indicated by the designations 36.37, 512 650 512 650 and 38.39, respectively. Figure 4 shows two openings, just like the trouser layer in Figure 7, but of slightly different sizes and shapes than the openings in Figure 7. The front opening 40 in the front portion 24 of the crotch portion 11 is triangular and larger than the rear opening 41 in the rear portion. The rear opening 41 is also the triangular one.

Figure 5 shows a variant with only a single opening 42. This single opening 42 is relatively much longer than any of the previously described openings, in order to be able to serve as an opening for the passage of both urine and faeces. The slightly wider end of the opening 42 is arranged in the front part 24 of the crotch portion 11 and the slightly narrower end of the opening 42 is arranged in the rear part 25 of the crotch portion 11.

In Fig. 3, in perspective view, the front part of the opening 34 in the inner part 24 of the crotch portion 11 of the trouser layer is shown. However, the opening 34 in Fig. 3 could also illustrate the front part of the only elongate opening 42 in Fig. 5, or the the front part of the front opening 40 in fi gur 4. It should be pointed out that the shape and size of the openings will change when the trouser layer 5 is exposed to ldafter, for example depending on how tight the trouser layer 5 fits around the user's body.

As previously described, an outer latch 6 is attached to the trouser leg 5, see for example Figures 1 and 8. The latch layer 6 is in this case arranged at a height with the openings 34, 3, see the lugs 7 and 8 which each show their side of the trouser leg. 5, and the outer barrier layer 6 is connected to the trouser layer 5 in areas 30-33 around the openings 34,35.

As previously stated, the trouser layer 5 has an opening 34 in the form of a hole within a front area 24 of the crotch portion 11 seen in the direction of the front waist portion 9, and an opening 35, also in the form of a hole, arranged within a rear area 25 of the branch portion 11, seen in the direction of the rear waist portion 10. These two openings 34,35 are intended for the passage of urine and faeces through the trouser layer 5 to the front and rear corners (not shown) between the trouser layer 5 and the outer barrier layer 6, which are to be shown. explained below.

Between the trouser layer 5 and the outer barrier layer 6, one or more of their absorbent bodies 7 are arranged. These may comprise any type (s) of known absorbent material, for example cellulosic pulp, superabsorbent polymers (by which are meant polymers having the capacity to absorb liquid many times over) IIIIIIIIIIIIIIII iiiii iiiiiii iiiiiiiiiiiiiiiii ii IIIIIIII IIIIIIIIIIIIIIII iiiiiiiiiii III III II III III IIII iiiiii II II II III III II III iiiiii iiiiiiiiiii iii .- ... Gmail II 10 15 20 512 650 19 own weight), for example crosslinked polyaloylater, absorbent foam or mixtures of these. The absorbent body is preferably covered by a liquid-permeable cover material, but this is not absolutely necessary. If the liquid-permeable cover material is present, it may, for example, consist of a nonwoven, of the thermobond or spunbond type and, for example, comprising polypropylene fibers.

Examples of absorbent bodies and liquid-permeable casing layers are shown in more detail in Figures 10-13, which are described in more detail below.

The pockets are delimited from each other so that transport of urine and faeces is prevented between the pockets. In the example according to Figures 1 and 8, this can be achieved in a manner not shown in the figures. For example, a liquid banner in the form of a tubular body or a hose body can be arranged between the trouser layer 5 and the absorbent body. This pipe or hose body extends transversely between the attachments 30,31 of the trouser layer in the side edges 28,29 of the outer barrier layer within an area between the two openings 34,35. The upper and lower sides of the hose cap are attached to the trouser layer 5 and the liquid-permeable cover layer on top of the absorbent body, by means of a connection with a small extent in the longitudinal direction of the trouser layer 5, for example by means of an adhesive string. The hose body can for instance consist of a polyethylene film which has been made tubular. Instead of a hose body which is two-walled, a single-walled barrier, for example a bellows-weighted polyethylene film, can be applied between the trouser layer 5 and the liquid-permeable cover layer. For details regarding suitable designs of such liquid banners, please refer to our Swedish patent application SE 9400916-4.

However, the liquid barrier, like the outer barrier layer 6, must be attached to the trouser layer 5 so that it is substantially unloaded within the same area as the outer barrier layer 6 of tensile force in the trouser layer 5, which is perpendicular to the longitudinal line of symmetry.

In this example, the absorbent cap extends with portions on both sides of the liquid barrier and this defined pockets apart in the void between the trouser layer 5 and the liquid-permeable casing layer of the absorbent body. However, this is sufficient to prevent the faeces from spreading from the posterior to the anterior one. In a variant, it is conceivable that two separate absorbent bodies are arranged in separate pockets and that the liquid barrier is arranged between the trouser layer 5 and the outer barrier layer 6.

UI 10 20 D.) UI 512 650 20 According to a further variant, only one absorption loop is arranged in the front corner and none at all in the rear in which only faeces are intended to be collected.

Optionally, an absorbent body with reduced absorption capacity can be arranged in the rear corner, in order to be able to absorb the loose fraction of the faeces.

It is also conceivable not to arrange an absorbent body in the traditional sense inside the jacket or jackets at all, but instead to cover the inside of the outer barrier layer with an absorbent material, the absorption capacity of which is adapted for the purpose of absorption. For example, a high-bulked fabric with hydraulic properties could be laminated or otherwise bonded to the inside of the outer barrier layer, i.e. on the inside of the box, or at least one of the boxes.

With reference to ur gures 2, 7 and 9, a further exemplary embodiment of a pair of trousers according to the invention will be described. This trousers 51 is identical to the trousers 1 according to Figure 1, with the exception of the design of the outer barrier. For this embodiment, fi gur 9 shows the opposite side of the trouser layer 5 in fi gur 7.

Trousers 51 have two separate barrier layers 52.53. A front barrier layer 52 is connected to the trouser layer 5 enclosing the opening 34 in the front part 24 of the crotch portion 11 and a rear barrier layer 53 is connected to the trouser layer 5 enclosing the opening 35 in the rear part 25 of the crotch portion 11. The space between the trouser layer 5 and the respective front and rear barrier layers 52.53, form a front edge 54 and a rear edge 55, respectively, see for example Figure 2. These corners are delimited from each other and in that the front and rear barrier layers 52.53 do not overlap but are separated. in the longitudinal length of the trouser layer.

An absorbent body 7a is arranged in the front corner 54 and an absorbent body 7b is arranged in the rear corner 55, see Figure 2. These absorbent bodies may be of the type described above.

In the same manner as in the previously described exemplary embodiments, the front and rear barrier layers 52, 53 are connected to a prestressed trouser layer 5. The barrier layers 52, 53 and side edges 56-59, respectively, are connected to the trouser layer 5 in areas 60-63 between the respective side seam 8 and the intended the longitudinal line of symmetry of the trouser layer 5. The barrier layers 52.53 according to the embodiment according to fi gures 2 and 9 each have two end edges 64.65 and 66.67, respectively. The respective end edges 64 and 67, respectively, which are closest to the respective end edge 12 and 13 of the trouser layer, respectively, are connected in Fig. 9 to portions 68.69 of the trouser layer 5 some distance inside the respective end edges 12,13 of the trouser layer. In Figure 2, the connection parties are 70.71 Illllllllllllllllllll llillnlnlllillllllll fi llllilii fi iäliiiàiliii fi ililnlllildilÉiiäim I 'irl-ull Il llll ll ll l ll || l l lIl | lll | lll || lll || ll || | ll | l | l l || ll | lll l l | llIll ||||||| lllllllllll | ll | l | l lllllllllllllll | llI | lll_ | l | || l | l ll |||||| ll || l | l || ll lll l || iillllli lll | ll | l ml nu lll | liinilill: lllmull-lll llllllllllll lllll ll ll lllllllllllllllllllllllllllllllll lllllllllllllll 10 15 25 512 650 2, arranged a further distance further in from the respective end edges of the trouser layer 12,13. In this context, it can be pointed out that the front 52 and the rear 53 barrier layer 64,67, respectively, could instead be attached to portions of the trouser layer end edges 12,13 in the same way as in the embodiment according to 1 figure 1 and vice versa. The adjacent end edges 65,66 of the respective front and rear barrier layers 52,53 are connected to the trouser layer 5 within areas 72,73 within a central area of the crotch panel 11. Hereby, the respective front and rear barrier layers 52,53 are connected around the respective opening 34,35 in the trouser layer 5.

With reference to Figures 10 to 10c, it will be described how an embodiment of a pair of trousers according to the invention is intended to work.

Figure 10 shows an absorbent trousers of the same type as in Figure 1. Trousers 1 are shown from the front in their intended position of use on a user indicated by solid and dashed lines. A portion of the trousers is shown in section and another portion thereof is circled and shown in magnification 10a.

Figures 10 and 10a show how the trouser leg 5 lies close to the user's body and follows up in the light fold. The trouser layer 5 is shown interrupted by the opening 34. Figure 10a also shows an absorbent body 80, the outer barrier layer 6 and a liquid-permeable cover layer 81 applied to the side of the absorbent body 80 facing the trouser layer 5. Between the trouser layer 5 and the liquid-permeable cover layer 81 an 82 82 is formed. Examples of all these elements have previously been mentioned above and are therefore not repeated here.

Figure 10b shows how urine 83 has entered the pocket 82 through the opening 34 and has not yet passed the liquid-permeable cover screen 81 and is absorbed by the absorbent body 80. This is not an abnormal situation as absorbent pants will often be tilted when the user is lying on side or bends in one way or another. In the position shown, therefore, the absorbent body 80 has not been able to absorb the liquid in the intended manner but instead collects in the completely enclosed corner of the box 82. Nothing will be able to leak either as the trouser layer 5 is hydrophobic and the outer barrier layer 6 is liquid impermeable. Because the trouser layer 5 is elastically adherent to the user's skin over substantially its entire surface and that, as previously mentioned, it will not be substantially affected by forces from the absorbent body or the outer barrier layer, it will also not release contact with the user's skin and also not to be moved from its position towards the user either laterally or longitudinally, in those so important for avoiding leakage. the areas around the opening 34 (or the openings if they are fl your). If the opening 34 is properly dimensioned and properly positioned in relation to the user's urethral orifice, all discharged urine will be able to be inserted with great accuracy into the hole 82, from which it can then not leak out, but is only absorbed by the absorbent body 80. If against the presence of any liquid penetrating between the trouser leg 5 and the user's skin at the edge of the opening 34, this liquid will have a relatively long way to flow before it leaks out over the edge of the trouser leg 5.

As a comparison with the present invention, Figure 10c shows an example of a known upright leakage barrier 90 for a diaper. The known leakage barrier 90 consists of a separate piece of material arranged on an elastic leg waistband 91. The diaper usually comprises an absorbent body 92, a liquid-permeable cover sleeve 93 and an outer barrier layer 94. The leakage barrier 90 comprises an elastic member 95 with raised from the liquid-permeable cover layer 93.

The outer barrier layer 94 constitutes the "pants-forming" layer of the composite diaper and is thus the layer which carries the loads of the diaper. As a result, the outer barrier layer may be moved in relation to the user as it is affected by forces. Since the leakage banners are in communication with the outer layer, it can thus also be moved in relation to the user. The leakage barrier 90 may therefore be forced to release its contact with the user or be moved laterally or longitudinally out of its intended position on the user. Since the leakage banner 90 has only a very narrow line of contact 96 towards the user, liquid will be able to cross the leakage barrier very quickly as soon as it loses contact with the user. Thereafter, only the sealing leg waistband 91 remains as a final outpost against leakage. Since it is also exposed to forces from the outer barrier layer, there is a great risk that it will not hold tight either. Incidentally, a major damage has already occurred as the liquid has passed the leakage barrier 90. In that case, the liquid will be in contact with the user's skin area outside the leakage banner 90 and inside the elastic leg waistband 91. This liquid will be able to create skin irritations, which of course gives the user discomfort.

It should be noted that if free liquid collected in the space between the leakage barrier 90 and the liquid permeable cover layer 93 accumulates against the leakage, it will accumulate against the leakage.

Figure 11 shows in a similar view as Figure 10 an absorbent trousers 111 according to a further embodiment of the invention. Figure 12 shows an enlargement of a portion between the legs of the user of the trousers in fi gur 11. The difference from the trousers according to fi gur 10, is that an even greater distance between the trousers layer 5 and the absorbent body 80 has been created compared to the trousers in fi gur 10. Thereby a deeper 84 cka 84 is obtained.

Figure 13 shows a similar magnification as Figure 12, but shows an alternative absorbent body 100, which comprises a larger main body 101, centrally arranged between two smaller side bodies, of which only one 102 is shown in the fi clock.

The side bodies 102 can be pivoted up at the hinge formed in the gap 104 between the respective side body 102 and the main body 101. In this way an 103 cka 103 is provided with an even greater depth than for the previously shown embodiments, but with retained amount of absorption capacity, compared to a single coherent absorption loop consisting of exactly the same absorption material.

The construction of the absorption body 100 is described in more detail in our Swedish patent application SE 9304131-7, to which reference is hereby made. The absorbent body 100 with a main body and side bodies can of course be used to advantage also in the previously shown embodiments.

The invention is described as a trousers for the absorption of urine. Such pants are usually called pants diapers. Known trouser diapers have sealed side seams by the manufacturer, possibly provided with the possibility of opening. However, the invention also relates to those diapers which can be opened and resealed and those which are supplied by the manufacturer in the open condition and which are equipped with fastening devices which are intended to be fastened together by the user in a manner instructed by the manufacturer, in order to be subsequently drawn. on the user in assembled trouser configuration.

Examples of such pant diapers have been given earlier in this description. The invention is also applicable to so-called pant bandages, ie trousers specially designed to absorb menstrual fluid.

As shown above, a number of modifications are possible within the scope of the invention and this may therefore only be considered to be limited by the appended claims.
