Description

"BARRIER FOR AN ABSORBENT PRODUCT" The present invention relates to an absorbent product such as a diaper, a panty diaper, an incontinence protector or the like, of the type in accordance with the preamble of claim 1, and the methods for making these products in accordance with the preamble of Claims 10 and 11. An absorbent product of this type is known from Patent Number WO-A 95/25493. A diaper made in accordance with the teachings of this document comprises a top sheet of flexible material and a bottom sheet of a liquid impervious material, and an absorbent body contained therebetween. The upper canvas is provided with front and rear longitudinal openings, the front opening being intended to receive the urine and the posterior opening being intended to receive the fecal material. The openings are separated by a bridge of material from the upper canvas. The upper canvas is free of connection with the absorbent body in the region of the openings. It is desirable in these products to prevent fecal matter from coming into contact with the genitals of users, particularly female users. In order to prevent fecal matters from moving forward and contacting the part of the absorbent body intended to receive the urine, a piece of additional flexible material is provided which extends transversely through the diaper between the absorbent body and the absorbent body. the upper canvas in the region between the two openings, and which is attached to both the absorbent body and the upper canvas. This piece of additional material forms a barrier that prevents the fecal material from entering the part of the absorbent body to which the urine is discharged, and in this way prevents the fecal material from coming into contact with the user's genitals. The use of a piece of additional material to form this barrier complicates the manufacturing process and leads to increased material costs. An object of the present invention is to provide, in a simple and cost effective manner, a barrier which will help to prevent fecal matter discharged into the absorbent body from moving forward to the region intended to receive urine. This object is achieved by using the material that is cut from the upper canvas when the openings are formed as the barrier material. According to one embodiment of the invention, the material that is cut to form one of the openings in the upper surface is left fixed to the upper canvas at the end of the opening that is closest to the other opening, in order to form a fin or tongue of upper canvas material. This flap is then folded, along its line of fixation with the upper canvas, towards the absorbent body and the end and / or sides of the flap furthest from the fastening line are fastened in the absorbent body. In this way, a barrier is formed without requiring any additional material. In another embodiment of the invention, the material in the form of a fin from an opening is used to form a first barrier, as described above, while the material in the form of a fin from the other opening is used. to form a second barrier. This second fin is cut longitudinally to form two fin halves. These fin halves are first folded, along the line of attachment with the upper canvas, to the absorbent body and then folded at an angle with respect to the fixation line so that they project laterally. The ends and / or sides of the fin halves are then attached to the absorbent body in a lateral position that is preferably farther from the longitudinal centerline of the product than the first barrier. In this way, a barrier with a greater lateral reach is provided.

In a particularly advantageous embodiment of the invention, a barrier is moved and fixed to the underlying surface or to an absorbent body offset to one side of a longitudinal center line, while the other is displaced and fixed off-center to the other side of the longitudinal center line. In this way, a zig-zag path is provided between the front and back sides of the diaper. This effectively prevents the stool from moving forward while at the same time allowing the urine to pass back to the back of the diaper, which increases the amount of absorption material available to receive the urine. In another embodiment of the invention, the material that is cut to form one of the openings in the upper surface is completely removed from the upper surface to form a strip of material which is then clamped between the lower side of the upper surface and the body absorbent in an appropriate position to form a barrier. The invention will be described in greater detail below with reference to the accompanying drawings of the examples of the modalities, wherein: Figure 1 shows a schematic perspective view taken obliquely from above, of a modality of a diaper according to the invention; Figure 2a shows a schematic illustration from above, of the diaper shown in Figure 1 in a planar state; Figure 2b shows a schematic illustration from above similar to that of Figure 2a, for a diaper without absorbent side bodies; Figure 3a shows a cross-sectional view along the line III-III in Figure 2a; Figure 3b shows a cross section similar to that of Figure 3a, for a diaper on the absorbent side bodies; Figure 4 shows a cross-sectional view along line IV-IV in Figure 2; Figure 5 shows a schematic illustration from above, of a second embodiment of a diaper according to the invention in a flat state; Figure 6 shows a cross-sectional view through the line VI-I in Figure 5, Figure 7 shows a cross-sectional view along the line VII-VII in Figure 5, Figure 8 shows a bend pattern for an additional mode of a fin; Figure 9 shows a bending pattern for another embodiment of a fin; and Figure 10 shows a partial fold pattern for yet another embodiment of a fin.

Figures 13a-d schematically show in perspective the steps for making a fin of the material present in the openings for the leg. Figure 13e shows a cross section, similar to that shown in Figure 3a, of the flap of Figure 13d in a diaper; Figure 14 shows a cross section similar to those shown in Figures 3a and 3b of another embodiment of a diaper according to the invention. Figure 1 shows a modality of a diaper 1 having a barrier according to the invention. The diaper has a front portion 3, a rear portion 5, an intermediate crotch portion 7, and leg openings 8. The diaper comprises, a top canvas 9 made of an upper canvas material, preferably impermeable to liquid such as polypropylene fibers and bound by spinning or non-woven carded, or the so-called SMS material (material bonded by melt-spinning -linked by spinning), a lower canvas 11 made of a lower canvas material, preferably impermeable to liquid, for example, a polythene film, an absorbent body 13 comprising a central body 14 and enclosed absorbent side bodies 14 ' between the upper 9 canvas and the lower 11 canvas. An absorbent body 13 is in contact with a lower canvas 11 above essentially the entire surface of the absorbent body 13 facing the lower canvas 11. A space 15 for retaining raw material and body fluids is provided between the absorbent body 13 and the upper canvas 9 through part of the surface of the absorbent body 13, which faces the upper canvas 9. The upper canvas 9 is provided with two openings 17, 19 separated by a bridge 21 of the upper canvas material. The bridge 21 is placed in the crotch portion 7 of the diaper 1 in a position intended to correspond to the region between the gels and the anus of a proposed user. The urine opening 17 is provided in the front portion 3 of the upper canvas 9 in an appropriate position to receive the urine emitted by a user. The urine opening 17 has a bridge end 23, two longitudinal sides 25,27 and a distal end 29. The urine opening 17 is formed by removing from the upper canvas 9 a piece of material (not shown) having the shape of the urine opening 17. The fecal opening 19 is provided in the rear portion 5 of the upper canvas 9 in a appropriate position to receive the fecal material excreted by the user. The fecal material opening 19 has a bridge end 31, two longitudinal sides 33,35 and a distal end 37. The opening 19 for fecal matter is formed by cutting the material 9 from the upper canvas along the longitudinal sides 33,35 and the distant end 37 so as to form a fin. or tongue 39 fixed to the bridge 21. The letter 39 has a bridge end 41, two longitudinal sides 43, 45 and a distant end 47. The wing 39 bends down along the bridge end 41 and the distant end 47 The fin 39 is attached to an absorbent body 13 in the crotch portion 7 of the diaper 1. In this example, the sides of the fins and the openings are shown as being essentially straight, but may be of any suitable shape, for example, curved Figure 2a shows schematically in a view from above the diaper of Figure 1 in a state - flat. In this Figure, the construction features of the diaper that are not related to the present invention have been omitted for reasons of clarity. Figure 2b shows a diaper embodiment similar to that shown in Figure 2, having a simpler absorbent body 14 that lacks the absorbent side bodies 14. "Figure 3a shows a cross-sectional view along the line IIIa- It will be seen here that the flap 39 extends from the upper surface 9 to the absorbent body 13. For reasons of clarity of illustration, the absorbent bodies 13, 14 and 14 'are shown simplified in this embodiment and they are drawn as if they had been made of a homogeneous absorbent material 16 of a surface material 18 covering the surface of the absorbent material which is intended to be oriented towards the upper canvas 9. In this embodiment, the surface material 18 is shown attached to the lower surface 11 between the central body 14 and the lateral bodies 14 as well as between the upper surface 9 and the lower surface 11. This is not intended as a limitation for the manner in which the absorbent bodies can be formed as it is naturally possible that they consist of any kind of absorbent medium comprising one or more different materials and / or layers of material, as will be described later. The expression "absorbent body" is therefore intended to refer to all the parts of the diaper that are intended to absorb and / or retain the fluid as well as the layers of material intended to: fix these parts to the diaper; and / or, prevent them from being damaged; and / or preventing them from coming into contact with the user's body through the holes made in the upper canvas 9. In this embodiment, this remote end 47 of the flap 39 is attached to the absorbent body 13 symmetrically with respect to the longitudinal center line of the diaper 1. It does not extend laterally to the longitudinal edges of the absorbent body 13 and acts only as a barrier with respect to to the movement of fecal matter in the central region of the absorbent body. Figure 3b shows a cross-sectional view through the lines IlIb-IIIb in Figure 2b. Figure 4 shows a cross-sectional view along the line IV-IV in Figure 2. It can be seen here that the fin 39 bends accordion-like between the bridge 21 and the absorbent body 13. In order to ensure that the fin 39, it can be advantageous to bend the upper canvas 9 of an elastic material or to provide the upper canvas material with an elastic means (not shown) at least in the longitudinal direction of the diaper and for pretensioning the material, at least in the longitudinal direction of the diaper, in such a way that the flap 39 tends to be pulled up on itself after being cut from the upper canvas 9. Even when the flap 39 is shown attached to an absorbent body 13 at a position below the bridge 21, it is possible that it could be attached to the absorbent body 13 at any suitable position, for example, forward below the opening 17 for urine and toward back below the opening 19 for fecal matter. The fin 39 does not have to be bent and can be made from only part of the material cut from the opening 19 for fecal material. Even when in this mode the barrier is formed of a fin 39 made of the material of the opening 19 for fecal matter it is of course possible to use the material remaining from the processing of the opening 19 for urine to form the barrier. It is also possible to use the material of both openings (or more openings that can be provided if necessary) to form a plurality of barriers and / or an extra-thick barrier. A second embodiment of the invention is shown in Figures 5 to 7. The features of this embodiment that correspond to the features in the embodiment shown in Figures 1 to 4 have the same reference numbers that were used in Figures 1 to 4. The absorbent body 13 is shown here for example reasons only, as a simple absorbent body made of, for example, an absorbent foam. In this embodiment, the material of the urine opening 17 is used to form a second fin 53. This fin 53 has a bridge end 55, two curved longitudinal sides 57,59 and a distal end 61. This fin is cut along its longitudinal center line to form two partial fins 53 'and 53' 'essentially of mirror image. The partial fin 53 'has a bridge end 55', a curved longitudinal side 57, a straight longitudinal side 58 and a distal end 61 '. The partial fin 53"has a bridge end 55", a straight longitudinal side 58, a curved longitudinal side 59 and a distal end 61". These partial fins 53 ', 53' 'are intended to form barriers with a greater lateral reach than that of the fin 39. This is achieved by bending the partial fins 53', 53 '' downwards to the absorbent body 13 and twisting each one. of them around an axis 65 ', 65' 'that is inclined towards the longitudinal direction of the partial fins 53', 53 '' so that the distal ends 61 ', 61' 'move away from the longitudinal center line of the body 13 absorbent. The distal ends 61 ', 61"may be attached to the longitudinal edges of the absorbent body 13 and / or to the lower canvas 11. In a variation of this embodiment, not shown, the flap 39 is completely removed from the bridge 21 and then fixed by its longitudinal edges 43.45 on the underside of the bridge 21 and the absorbent body 13. In this way, a wider barrier can be achieved. Figure 8 shows a fold pattern for the additional mode of a fin 53, where the axes 65 ', 65"are inclined at an angle I = 45 / up to the longitudinal axis of the partial fins 53', 53 '' in such a way that the twisted partial fins 53 ', 53"(which are shown by dashed lines) are essentially perpendicular to the plane of the lower surface 67 of the upper canvas 9. If desired, the partial fins 53 ', 53' 'can then be fixed to the lower surface 67 of the upper canvas 9. Figure 9 shows a fold pattern of a further embodiment of the invention in which the longitudinal cut forming the partial fins 53 ', 53"does not extend completely from the end 61 distant to the bridge end 55. In this way, a barrier can be produced which extends first vertically downwards before then extending laterally. This barrier can be fixed to the absorption body by the fold lines 65 'and / or by some or all of the edges of the partial fins in order to provide a wider barrier. Figure 10 shows an intermediate position in a fold pattern of the additional embodiment of the invention in which only one of the partial fins is shown folded. Here, the longitudinal cut forming the partial fins 53 ', 53"does not extend completely from the end 61 distant to the bridge end 55, and the partial fins 53', 53" twist laterally so that the end 61 'Distant fin 53' on the right extends to the left and the far end of the fin on the left extends to the right. Figure 11 shows in plan view the preferred embodiment of a diaper in accordance with the invention. This diaper is similar to the diaper shown in Figures 2 to 4 and the same reference numerals are used to refer to the particularities that are common to both modalities. In this embodiment, the material of the urine opening 17 is used to form a fin 71 hinged on the bridge 21. The fin 71 has sides 73, 77 and a distal end 75. The flap 71 is bent and fixed by its end 75 remote from the absorbent body 13 on one side of a longitudinal center line of the diaper 1, while the flap 39 is attached to the absorbent body 13 on the other side of the longitudinal centerline of the diaphragm. diaper. In this way, a non-symmetric barrier is formed. In order to pass from one side of the barrier to the other side, the waste products must march in a zigzag path. Figure 12a shows a section along the line XII-XII in Figure 11. The dashed lines show the manner in which the fins 39, 71 can also be attached to the lateral absorbent bodies 14 'if there is sufficient fin material . Figure 12b shows a section corresponding to 12a for a diaper without lateral absorbent bodies 14 '. Figures 13a-13d show an embodiment of the manner in which the material 79 ', 79"of the leg openings 8 in a piece of eg the upper canvas material 9 can be cut and bent to form a barrier 81. As shown in Figure 13a, each leg opening 8 is formed by cutting a curved flap 79 ', 79"of material from the opposite longitudinal sides 83', 83" of the upper canvas 9. The fins 79 ', 79"are fixed to or remain fixed to the upper canvas 9 by a bridge end 80', 80" in the bridge region 21. Each flap 79 ', 79"has longitudinal sides 82', 82", 84, 84"and a distal end 86 ', 86". In Figure 13b, the manner in which the two prongs 85 ', respectively 85' 'of each fin 79', 79 '' can be folded towards one another outside the plane of the upper canvas 9 to form a semi-barrier 87 can be seen. ', 87' 'which has a double thickness of the upper canvas material. These half-barriers 87 ', 87' 'can then be bent along their fastening line with the bridge 21, as shown in Figure 13c until they meet and possibly partially overlap under the bridge 21, to form a barrier, as shown in Figure 13d. This barrier can be fixed to the underside of the bridge 21 and to the absorbent body when the diaper is armed. Shown also in Figure 13d are the sides 89, 91, the bridge end 93 and the distal ends 95 of the leg openings 8. Figure 13e shows a cross section through a diaper after the body 13 absorbs and the lower layer 11 has been placed under the upper canvas 9, but before they have been fixed to the upper canvas 9 and the half-barriers 87 ', 87". Of course it is possible to bend the fins in other ways. It is also possible to use only the material from one of the leg openings to form the barrier or to use a combination of elaborate barriers of the leg opening, the opening for urine and the material of the opening for the fecal matter. It is also possible that the absorbent product is provided with only one opening for receiving body fluids and raw material, in which case the barrier formed by the fin material from the leg openings can be used to divide the single opening in two in order to form separate receptors for fecal matter and body fluid. In order to achieve the best sealing between the user's body between the genitals and the anus, and the upper canvas of an absorbent product in accordance with the invention, it is important that the barrier does not tend to pull the upper canvas away from contact with the body of the user. Therefore, it is preferred that the barrier be of sufficient depth such that even when the absorbent body is full of debris, and therefore tends to warp downward, no forces are transmitted to the upper canvas through the barrier . Advantageously, the upper canvas can be elastic, at least in the lateral direction so that it tends to adhere to the wearer's body. The upper canvas can be made of an elastic film which is pre-stretched before being fixed to the rest of the absorbent product in order to provide the required elastic force. Alternatively, the upper canvas can be made of one or more films or sheets of non-elastic material, which is sei they provide with properly tensioned elastic means, such as elastic threads or ribbons or the like. These elastic means, for example, can be provided only in the lateral or longitudinal directions of the finished product, or in both directions or in any direction. It is also possible that the upper canvas has a different elastic means in different parts of the upper canvas, for example, the upper canvas could be laterally elastic in the front and back and longitudinally elastic parts in the crotch part. However, it is particularly advantageous that the elastic force is provided in the direction that ensures that when a fin is fixed between the upper canvas and an absorbent body in an absorbent product, then the elastic force is perpendicular to the plane of the placed product. In other words, the elastic force should tend to cause the flap to bend up on itself in a manner similar to an accordion. Naturally, this elastic force must be adapted in such a way that it does not pull the upper canvas away from the user's body. Therefore, it may be appropriate for the elastic force in the lateral direction of the upper canvas, at least in the crotch region, an absorbent product, to be greater than the elastic force in the longitudinal direction in order to overcome the deductive force exerted. by the fin.

An example of a diaper in accordance with the inven that is provided with an elastic upper canvas is shown in Figure 14. The upper canvas 9 comprises an elastic net of lateral elastic fibers 99 and longitudinal elastic fibers 101 between the upper surface layer 103 and a lower surface layer 105. The fibers 99, 101 are preferably pre-stressed, for example, elongated before being fixed to one or more of the surface layers 103, 105. If the longitudinal fibers 101 are fixed along all their While the lateral fibers 99 are fixed only by their ends, it is then possible to cut the fins that stretch elastically considerably only in the longitudinal direction. The upper surface layer 103 and the lower surface layer 105 may be of any suitable material such as a non-woven material impervious to liquid, and preferably are bonded to one another (not shown for reasons of clarity in Figure 14) in the regions between the elastic fibers 99, 101. This attachment can be achieved, for example, by gumming, heat sealing, ultrasonic bonding or any other suitable means. In this embodiment, the upper canvas 9 extends outwardly beyond the limit of the lower canvas 11.

In case of a diaper according to the inven wherein the upper canvas has different elastic regions, e.g. regions where there is a greater elastic pre-stress in one direction than in the other direction, it is possible to use only part of the upper canvas material removable from an opening to form the fin. Therefore, if the upper canvas material in the crotch region is pre-stretched longitudinally while the front and rear regions are pre-stressed laterally, then the part of the fin that is formed from the material of the front or rear regions it will tend to bend laterally, while the part from the crotch region will tend to fold up longitudinally. In order to avoid problems that may occur when trying to fix one end bent laterally to a fin with another surface, e.g. the lower surface, it may be advantageous to remove the pre-stressed material laterally from the flap and to use only the longitudinally stressed portion to form the "barrier." Even though the inven has been illustrated by examples of diapers, it is also applicable to other types. of absorbent products such as a panty and a diaper, an incoence protector or the like The embodiments shown above may be modified within the scope of the inven, for example, changing the shapes of the openings, the number of openings and their sizes. In addition, the fins can be cut to form more than two partial fins and the partial fins do not have to be symmetrical and do not have to be placed symmetrically. The partial fins may also optionally be provided in both or all of the openings. It is also possible to vary its fixation to the other parts of the absorbent product so that they can be fixed by their sides and / or the ends in any of the constituent parts of the product. The fins may have straight or curved sides and / or edges. The flaps can also be fixed directly to the lower layer if necessary or if desired, for example, if the absorbent body consists of two elongated absorbent means placed on either side of the longitudinal center line of the diaper and separated by an exposed upper surface of the diaper. the lower layer then, in order to block the central region of the diaper, it is necessary that a fin be attached to this exposed upper surface of the lower layer. A similar situation occurs if the absorbent body consists of two or more absorbent means placed on either side of the lateral dividing line, for example, in the case where separate absorbent means are provided in part 2 front and back of the diaper for liquid waste, respectively solid. The invention is not limited to the use of the material from the opening in the upper canvas, but it is also conceivable to form the barrier flaps of another material that would normally be wasted during manufacture. An example of this material is the material removed to form the leg openings in the lower canvas. The invention is suitable for use in absorbent bodies of any type, for example, absorbent bodies made of one or more absorbent materials, for example, cellulose foam with or without a superabsorbent polymer, absorbent foam and may comprise one or more layers of absorbent material. absorbent material, and if necessary, additional layers of a material that improves absorption, embedding or prevents friction. It is naturally possible for an expert person to combine the particularities of the different modalities shown as examples shown and described as non-limiting, as required. That is, for example, in this way it is possible to use a top canvas made of an elastic laminate of a non-woven elastic fiber and non-woven layers of any type of barrier construction and any type of absorbent body.

The barrier may be fixed by any appropriate means, such as, but not limited to, adhesive bonding, heat sealing, welding, ultrasonic bonding, sewing and these means may also be used to join together the other constituent parts of the absorbent product. The materials used for the absorbent product are preferably recyclable, biologically degradable and / or made from renewable resources.
