Description
Couche-culotte munie de poches latérales d'étanchéité et de
poches de ceinture d'étanchéité.Diaper with side sealing pockets and
sealing belt pockets.
La présente invention est relative à une couche-culotte pour enfants en bas age ou personnes incontinentes, du type comprenant une feuille extérieure imperméable aux liquides, capable de recevoir lln matelas absorbant, l'ensemble étant conformé de façon à laisser de chaque côté latéral de la couche-culotte une échancrure de passage des jambes. The present invention relates to a diaper for infants or incontinent people, of the type comprising an outer sheet impermeable to liquids, capable of receiving an absorbent mattress, the assembly being shaped so as to leave on each lateral side of the diaper a leg passage notch.
On connaît déjà des couches-culottes de ce type qui sont fabriquées en grande série en continu, à partir d'un film continu de matière synthétique, par exemple en polyéthylène mince, qui est déroulé d'une bobine et enduit de lignes ou bandes de colle du type thermofusible (dite "holt melt" dans la technique habituelle). Des matelas absorbants individuels sont déposés à intervalles sur le film continu. Puis une bande continue de matière perméable, par exemple en non-tissé, est appliquée sur le film de matière synthétique imperméable et sur les matelas absorbants de manière à adhérer à ladite feuille imperméable au moins le long de ses bords longitudinaux. Des éléments élastiques longitudinaux sont déposés et fixés à l'état tendu sur le film continu de matière synthétique imperméable ou sur la bande de matière perméable en non-tissé de chaque côté des bords longitudinaux du matelas absorbant dans la zone de l'entrejambes. Des découpes sont ensuite pratiquées dans l'ensemble ainsi formé dans la zone d'entre-jambes afin de donner une forme anatomique à la couche-culotte en conservant cependant dans les parties avant et arrière de celle-ci une largeur très supérieure à celle des parties avant et arrière correspondantes du matelas absorbant. Diapers of this type are already known which are produced in large series continuously, from a continuous film of synthetic material, for example of thin polyethylene, which is unwound from a reel and coated with lines or strips of glue of the hot-melt type (called "holt melt" in the usual technique). Individual absorbent pads are deposited at intervals on the continuous film. Then a continuous strip of permeable material, for example nonwoven, is applied to the waterproof plastic film and to the absorbent pads so as to adhere to said waterproof sheet at least along its longitudinal edges. Longitudinal elastic elements are deposited and fixed in the stretched state on the continuous film of impermeable synthetic material or on the strip of permeable nonwoven material on each side of the longitudinal edges of the absorbent mat in the crotch area. Cut-outs are then made in the assembly thus formed in the crotch area in order to give an anatomical shape to the diaper, while however retaining in the front and rear parts thereof a width much greater than that of the corresponding front and rear parts of the absorbent mattress.
Dans certains cas, il est également possible de ne pas fixer par collage les matelas absorbant individuels à demeure sur le film continu de matière synthétique imperméable mais au contraire de constituer la couche-culotte sous la forme d'une enveloppe réutilisable à l'intérieur de laquelle peut ensuite être introduit un insert sous la forme d'un élément absorbant jetabIe après usage. In some cases, it is also possible not to attach the individual absorbent mattresses permanently to the continuous film of impermeable synthetic material by gluing, but on the contrary to constitute the diaper in the form of a reusable envelope inside. which can then be inserted an insert in the form of a disposable absorbent element after use.
Dans tous les cas ces procédés et produits connus présentent l'inconvénient de nécessiter une consommation importante et inutile des matières premières constituant la feuille extérieure imperméable de la couche-culotte ainsi qu'éventuellement la feuille perméable intérieure en raison des pertes entraînées par les découpes pratiquées dans la zone d'entre-jambes de façon à former des passages de jambes adaptés à l'anatomie de l'utilisateur. In all cases, these known processes and products have the disadvantage of requiring a large and unnecessary consumption of the raw materials constituting the impermeable outer sheet of the diaper as well as possibly the inner permeable sheet due to the losses caused by the cuts made. in the crotch area so as to form leg passages adapted to the anatomy of the user.
Dans certaines couches-culottes de type connu comme décrit par exemple dans la demande de brevet français 2231 329 (STILLE
WERNER) les découpes pour le passage des jambes sont évitées mais il en résulte une mauvaise étanchéité à l'endroit de ces passages.In certain diapers of known type as described for example in French patent application 2231 329 (STILLE
WERNER) cuts for the passage of the legs are avoided but this results in poor sealing at the location of these passages.
L'invention a donc pour objet de résoudre les difficultés de l'état de la technique antérieure et en particulier de permettre la constitution de passages latéraux pour les jambes qui soient à la fois convenablement échancrés et rendus parfaitement étanches aux liquides. The object of the invention is therefore to solve the difficulties of the state of the prior art and in particular to allow the creation of lateral passages for the legs which are both suitably indented and made perfectly liquid-tight.
L'invention permet ainsi de réduire considérablement la consommation de matière première rencontrée dans la plupart des procédés classiques de fabrication de couches-culotte réduisant ainsi le prix de revient de ces produits tout en assurant une excellente étanchéité en particulier à l'endroit des passages latéraux pour les jambes. The invention thus makes it possible to considerably reduce the consumption of raw material encountered in most conventional methods of manufacturing diapers, thus reducing the cost price of these products while ensuring excellent sealing, in particular at the location of the lateral passages. for the legs.
La couche-culotte pour enfants en bas âge ou personnes incontinentes selon l'invention est du type comprenant une feuille extérieure imperméable aux liquides de forme générale allongée munie d'une partie avant et d'une partie arrière. La feuille imperméable est capable de recevoir un matelas absorbant également de forme générale allongée placé sur la feuille imperméable, le matelas absorbant pouvant être recouvert d'une feuille intérieure perméable aux liquides. The diaper for young children or incontinent people according to the invention is of the type comprising an outer sheet impermeable to liquids of generally elongated shape provided with a front part and a rear part. The waterproof sheet is capable of receiving an absorbent mattress also of generally elongated shape placed on the waterproof sheet, the absorbent mattress can be covered with an interior sheet permeable to liquids.
L'ensemble est conformé de façon à laisser de chaque côté latéral de la couche-culotte une échancrure de passage des jambes. Des dispositifs d'attaches adhésives peuvent en outre être prévus au voisinage des bords latéraux de la partie arrière de la feuille imperméable.The assembly is shaped so as to leave on each lateral side of the diaper a leg passage notch. Adhesive fastening devices may also be provided in the vicinity of the lateral edges of the rear part of the impermeable sheet.
La feuille extérieure imperméable présente sensiblement la même largeur sur toute la longueur de la couche-culotte. Deux barrières d'étanchéité latérales formées de bandes de matière perméable ou imperméable aux liquides, munies d'au moins un élément élastique au voisinage de leur bord dirigé vers l'axe de la couche-culotte, sont- prévues de chaque côté sur la longueur de la couche-culotte de façon à être situées à l'intérieur des zones marginales du matelas absorbant en formant des poches d'étanchéité latérales. The waterproof outer sheet has substantially the same width over the entire length of the diaper. Two lateral sealing barriers formed from strips of material permeable or impermeable to liquids, provided with at least one elastic element in the vicinity of their edge directed towards the axis of the diaper, are provided on each side along the length of the diaper so as to be located inside the marginal areas of the absorbent mattress by forming lateral sealing pockets.
Deux bandes transversales imperméables aux liquides sont fixées à la feuille extérieure imperméable aux liquides et/ou à la feuille intérieure perméable aux liquides dans les zones respectivement de la partie avant et de la partie arrière de ladite feuille extérieure imperméable. Les deux bandes transversales présentent des dimensions transversales supérieures à la largeur de la feuille extérieure imperméable. Two transverse bands impermeable to liquids are fixed to the outer liquid-impermeable sheet and / or to the inner liquid-permeable sheet in the areas respectively of the front part and of the rear part of said impermeable outer sheet. The two transverse strips have transverse dimensions greater than the width of the impermeable outer sheet.
Dans ces conditions, l'ensemble formé, en particulier par la feuille extérieure imperméable et les deux bandes transversales de largeur plus importante, constitue des passages latéraux pour les jambes, convenablement échancrés. L'étanchéité latérale est parfaitement assurée par les deux barrières d'étanchéité latérales formant des poches d'étanchéité. Under these conditions, the assembly formed, in particular by the impermeable outer sheet and the two transverse strips of greater width, constitutes lateral passages for the legs, suitably indented. The lateral sealing is perfectly ensured by the two lateral sealing barriers forming sealing pockets.
Les bandes transversales imperméables aux liquides comprennent de préférence au moins une portion transversale élastifiée. Elles constituent ainsi des barrières transversales avant et arrière imperméables et des portions de ceinture élastique pour la coucheculotte. The liquid impermeable transverse bands preferably comprise at least one elasticized transverse portion. They thus constitute impermeable transverse front and rear barriers and elastic waistband portions for the pantyhose.
Les bords longitudinaux de la feuille imperméable peuvent dans un mode de réalisation avantageux, être repliés en Z de chaque côté du matelas absorbant sur la longueur de la couche-culotte. Les deux barrières d'étanchéité latérales peuvent alors être fixées aux bords longitudinaux de la feuille imperméable sur la portion repliée se trouvant sensiblement dans le même plan que la face intérieure du matelas absorbant. Une telle fixation des barrières d'étanchéité latérales permet d'augmenter notablement leur efficacité en améliorant le contact desdites barrières d'étanchéité avec les cuisses de l'utilisateur de la couche-culotte. The longitudinal edges of the waterproof sheet can in an advantageous embodiment be folded in a Z on each side of the absorbent mattress along the length of the diaper. The two lateral sealing barriers can then be fixed to the longitudinal edges of the impermeable sheet on the folded portion lying substantially in the same plane as the inner face of the absorbent mattress. Such fixing of the lateral sealing barriers makes it possible to significantly increase their efficiency by improving the contact of said sealing barriers with the thighs of the user of the diaper.
De préférence, un ou plusieurs éléments élastiques longitudinaux sont fixés à l'état tendu sur les bords longitudinaux de la feuille imperméable, au moins dans la zone des passages latéraux pour les jambes, de chaque côté du matelas absorbant de façon à améliorer la. Preferably, one or more longitudinal elastic elements are fixed in the stretched state on the longitudinal edges of the impermeable sheet, at least in the zone of the lateral passages for the legs, on each side of the absorbent mattress so as to improve the.
conformation de la couche-culotte à l'anatomie de l'utilisateur tout en participant à l'étanchéité latérale.conformation of the diaper to the anatomy of the user while participating in lateral tightness.
Dans certains modes de réalisation, le matelas absorbant peut être fixé à demeure sur la face interne de la feuille extérieure imperméable en étant enserré entre celle-ci et une feuille intérieure perméable. In certain embodiments, the absorbent mattress can be fixed permanently to the internal face of the impermeable outer sheet by being sandwiched between the latter and a permeable inner sheet.
Les barrières d'étanchéité latérales peuvent être fixées avantageusement sur la face intérieure de la feuille perméable au voisinage des bords longitudinaux du matelas absorbant. The lateral sealing barriers can advantageously be fixed on the inner face of the permeable sheet in the vicinity of the longitudinal edges of the absorbent mat.
Dans une variante, permettant la formation de doubles poches d'étanchéité, les deux barrières d'étanchéité latérales sont fixées dans leurs zones centrales, chacun de leurs bords libres présentant un élément élastique. Chaque barrière d'étanchéité latérale forme ainsi une double poche d'étanchéité au voisinage du bord longitudinal correspondant du matelas absorbant. In a variant, allowing the formation of double sealing pockets, the two lateral sealing barriers are fixed in their central zones, each of their free edges having an elastic element. Each lateral sealing barrier thus forms a double sealing pocket in the vicinity of the corresponding longitudinal edge of the absorbent mat.
Dans d'autres modes de réalisation, le matelas absorbant peut être simplement inséré de manière amovible à l'intérieur d'une enveloppe réutilisable constituée par la feuille extérieure imperméable, les deux barrières d'étanchéité latérales et les deux bandes transversales impermables. Pour la réalisation d'une telle enveloppe, il est préférable que les bords longitudinaux de la feuille imperméable soient repliés en Z comme il a été indiqué précédemment. In other embodiments, the absorbent mattress can be simply inserted in a removable manner inside a reusable envelope constituted by the waterproof outer sheet, the two lateral sealing barriers and the two waterproof transverse strips. For the realization of such an envelope, it is preferable that the longitudinal edges of the impermeable sheet are folded in Z as it was indicated previously.
Dans tous les cas, les dispositifs d'attaches adhésives sont avantageusement fixés directement sur la bande transversale située dans la zone de la partie arrière de la feuille extérieure imperméable. In all cases, the adhesive fastening devices are advantageously fixed directly to the transverse strip located in the region of the rear part of the impermeable outer sheet.

Telle qu'elle est illustrée sur les figures 1 à 4, la couche-culotte selon l'invention, comprend une feuille extérieure imperméable aux liquides 1 réalisée par exemple en polyéthylène qui a été obtenue à partir d'un film continu de matière synthétique d'une largeur inférieure à la largeur de la couche-culotte finie, la différence de largeur étant égale à 2A 1. La largeur de la feuille 1 est cependant suffisante pour dépasser légèrement les dimensions transversales des bords d'extrémité avant et arrière du matelas absorbant 2, le bord avant 2a se trouvant dans la partie inférieure de la figure 1 tandis que le bord arrière 2b se trouve dans la partie supérieure de la figure 1. Une bande continue de matière perméable 3 de largeur égale ou légèrement inférieure à celle du film 1 est collée sur la face intérieure dudit film après qu'une succession de matelas absorbants 2 disposés à intervalles réguliers aient été fixés par collage sur ledit film 1. Dans ces conditions, on comprend que le collage de la bande de matière perméable 3 se fait tout autour des différents matelas absorbants 2 dans les zones 6 du film 1. As illustrated in FIGS. 1 to 4, the diaper according to the invention comprises an outer sheet impermeable to liquids 1 produced for example from polyethylene which has been obtained from a continuous film of synthetic material d 'a width less than the width of the finished diaper, the difference in width being equal to 2A 1. The width of the sheet 1 is however sufficient to slightly exceed the transverse dimensions of the front and rear end edges of the absorbent mattress 2, the front edge 2a being in the lower part of FIG. 1 while the rear edge 2b is in the upper part of FIG. 1. A continuous strip of permeable material 3 of width equal to or slightly less than that of the film 1 is bonded to the inner face of said film after a succession of absorbent pads 2 arranged at regular intervals have been fixed by bonding to said film 1 Under these conditions, it is understood that the bonding of the strip of permeable material 3 takes place all around the various absorbent mattresses 2 in the zones 6 of the film 1.
Des barrières d'étanchéité latérales 9 visibles également sur la figure 3 sont formées de bandes de matière perméable par exemple en une matière non-tissée munie d'un élément élastique 10 au voisinage de leurs bordures situées vers l'axe longitudinal de la couche-culotte. Lateral sealing barriers 9, also visible in FIG. 3, are formed of strips of permeable material, for example of a nonwoven material provided with an elastic element 10 near their edges situated towards the longitudinal axis of the layer. cheeky.
Comme on peut le voir sur la figure 3, l'élément élastique 10 est enserré dans une bordure repliée de la barrière d'étanchéité latérale 9.As can be seen in FIG. 3, the elastic element 10 is enclosed in a folded edge of the lateral sealing barrier 9.
Les barrières d'étanchéité latérales 9 sont déposées dans la fabrication.The lateral sealing barriers 9 are deposited in the manufacturing.
sur la feuille intérieure perméable 3 c'est-à-dire du côté intérieur de celle-ci et fixées sur ladite feuille perméable 3 au moyen d'au moins une ligne de collage longitudinale continue 1 I au voisinage des bords longitudinaux du matelas absorbant 2. Comme on peut le voir sur la figure 3, la ligne de collage 1 1 se trouve au-dessus c'est-à-dire vers l'intérieur du matelas absorbant 2 au voisinage de son bord longitudinal. Les barrières d'étanchéité latérales 9 munies de leur élément élastique 10 sont ainsi capables de former des poches d'étanchéité sur les bords longitudinaux du matelas absorbant 2.on the permeable inner sheet 3 that is to say on the inner side thereof and fixed on said permeable sheet 3 by means of at least one continuous longitudinal gluing line 1 I in the vicinity of the longitudinal edges of the absorbent mattress 2 As can be seen in FIG. 3, the bonding line 11 is located above, that is to say towards the inside of the absorbent mattress 2 in the vicinity of its longitudinal edge. The lateral sealing barriers 9 provided with their elastic element 10 are thus capable of forming sealing pockets on the longitudinal edges of the absorbent mattress 2.
Dans une étape suivante de la fabrication, des bandes transversales 12 sont déposées à intervalles réguliers perpendiculairement au sens de fabrication des couches-culottes et par-dessus la bande continue de matière perméable 3 et les extrémités longitudinales des barrières d'étanchéité latérales 9. Les bandes transversales 12 présentent des dimensions transversales par rapport à l'axe longitudinal de la couche-culotte supérieures de 2A 1 à la largeur du film 1 de matière synthétique. La bande transversale 12 est disposée de manière symétrique de façon à laisser subsister de chaque côté une portion de largeur A I comme on peut le voir sur la figure 1. In a following manufacturing step, transverse strips 12 are deposited at regular intervals perpendicular to the direction of manufacture of the diapers and over the continuous strip of permeable material 3 and the longitudinal ends of the lateral sealing barriers 9. The transverse bands 12 have dimensions transverse to the longitudinal axis of the diaper 2A 1 greater than the width of the film 1 of synthetic material. The transverse strip 12 is arranged symmetrically so as to leave on each side a portion of width A I as can be seen in FIG. 1.
La longueur, dans le sens de la fabrication, de la bande transversale 12 est égale à 2A, A étant la distance qui sépare le bord transversal de la couche-culotte ultérieurement fabriquée d'une zone située au-dessus d'un matelas absorbant 2 à proximité de son bord transversal recouvrant sensiblement les parties respectives avant et arrière 2a, 2b.The length, in the manufacturing direction, of the transverse strip 12 is equal to 2A, A being the distance which separates the transverse edge of the diaper subsequently manufactured from an area situated above an absorbent mattress 2 near its transverse edge substantially covering the respective front and rear parts 2a, 2b.
Les bandes transversales 12 peuvent être constituées par un matériau composite imperméable aux liquides et élastifié sur au moins une partie de sa longueur. A titre d'exemple on a représenté sur la figure 2 une bande transversale imperméable 12 comprenant successivement depuis l'intérieur vers l'extérieur, une bande de nontissé perméable aux liquides 4, un film de polyéthylène imperméable 13 et un élément élastique 8 en bande destiné à constituer une portion de ceinture élastifiée pour la couche-culotte après fabrication. The transverse bands 12 can be made of a composite material impermeable to liquids and elasticized over at least part of its length. By way of example, FIG. 2 shows an impermeable transverse strip 12 comprising successively from the inside to the outside, a liquid-permeable nonwoven strip 4, an impermeable polyethylene film 13 and an elastic element 8 in strip form. intended to constitute an elasticated belt portion for the diaper after manufacture.
Les bandes transversales imperméables 12 sont fixées à la bande continue perméable 3 et/ou au film de matière synthétique imperméable 1 par tous moyens tels que collage, thermoscellage ouautres. The waterproof transverse strips 12 are fixed to the permeable continuous strip 3 and / or to the waterproof plastic film 1 by any means such as bonding, heat sealing or the like.
Une pluralité d'éléments élastiques 5 constitués par exemple par des brins minces au nombre de quatre dans l'exemple illustré, sont fixés à l'état tendu parallèlement les uns aux autres de chaque côté du matelas absorbant 2 dans les zones marginales 6 du film continu imperméable 1. A plurality of elastic elements 5 constituted for example by thin strands four in number in the example illustrated, are fixed in the stretched state parallel to each other on each side of the absorbent mattress 2 in the marginal zones 6 of the film continuous waterproof 1.
Dans l'exemple illustré sur la figure 1, on a en outre procédé à une découpe 14 dans chacun des bords latéraux de l'ensemble ainsi formé, dans la zone destinée à constituer ultérieurement les passages latéraux pour les jambes de la couche-culotte, afin d'en améliorer l'adaptation anatomique. Ces découpes 14 sont pratiquées dans le film 1, la bande 3 et les bandes transversales 12. Les parties de matière supprimées ont été représentées sous forme hachurée sur la figure 1. Par rapport à la fabrication de couches-culottes classiques dans lesquelles le film continu 1 présente la largeur définitive de la couche-culotte, il apparaît que le procédé de l'invention permet de réaliser une économie substantielle en matières premières à la fois en ce qui concerne le film imperméable généralement en polyéthylène et la feuille perméable généralement en non-tissé. La surface économisée est proche de 2A 1 x la longueur de ltentrejambes, pour chaque couche-culotte produite. In the example illustrated in FIG. 1, a cutout 14 has also been made in each of the lateral edges of the assembly thus formed, in the zone intended to subsequently constitute the lateral passages for the legs of the diaper, in order to improve the anatomical adaptation. These cutouts 14 are made in the film 1, the strip 3 and the transverse strips 12. The parts of material removed have been shown in hatched form in FIG. 1. With respect to the manufacture of conventional diapers in which the film continues 1 shows the final width of the diaper, it appears that the process of the invention makes it possible to achieve a substantial saving in raw materials both with regard to the waterproof film generally made of polyethylene and the permeable sheet generally made of non woven. The area saved is close to 2A 1 x the length of the crotch, for each diaper produced.
La dernière étape de fabrication consiste à découper transversalement la structure composite continue ainsi obtenue, pour former une succession de couches-culottes individuelles. La découpe se fait dans la zone située entre deux matelas absorbants successifs 2 séparant ainsi chaque bande transversale 12 en deux parties égales de longueur A se trouvant situées comme visible sur la figure 1 dans les zones respectives de la partie avant 2a et de la partie arrière 2b du matelas absorbant et de la feuille extérieure imperméable I. En cours de cette opération, les extrémités non encollées des éléments élastiques 5 se trouvent généralement rétractées à l'intérieur des éléments de la couche-culotte. The last manufacturing step consists in cutting the continuous composite structure thus obtained transversely, to form a succession of individual diapers. The cut is made in the area between two successive absorbent pads 2 thus separating each transverse strip 12 into two equal parts of length A being located as visible in FIG. 1 in the respective areas of the front part 2a and the rear part. 2b of the absorbent mattress and of the impermeable outer sheet I. During this operation, the non-glued ends of the elastic elements 5 are generally retracted inside the elements of the diaper.
Les couches-culottes obtenues sont pourvues dans leurs zones d'extrémité avant et arrière de barrières d'étanchéité transversales élastifiées constituées par les bandes transversales 12 munies des zones élastifiées 8 qui forment en quelque sorte des pochesd'étanchéité de ceinture. Comme on peut le noter en effet sur la figure 2, le bord transversal libre de la bande transversale 12 se trouvant audessus du matelas absorbant 2 forme effectivement une poche d'étanchéité de ceinture de largeur A. The diapers obtained are provided in their front and rear end zones with elasticized transverse sealing barriers constituted by the transverse bands 12 provided with the elasticized zones 8 which in a way form waist seal pockets. As can be noted in fact in FIG. 2, the free transverse edge of the transverse strip 12 lying above the absorbent mattress 2 effectively forms a belt sealing pocket of width A.
On remarquera que les attaches adhésives 7 sont fixées directement sur la bande transversale 12 correspondant à la partie arrière de la couche-culotte. It will be noted that the adhesive fasteners 7 are fixed directly to the transverse strip 12 corresponding to the rear part of the diaper.
Par ailleurs, l'examen de la figure 3 montre que la couche-culotte comporte en outre des poches d'étanchéité latérales constituées par les barrières 9 élastifiées dont les bords libres se trouvent également audessus du matelas absorbant 2 c'est-à-dire du côté de sa face intérieure. Furthermore, the examination of FIG. 3 shows that the diaper also has lateral sealing pockets formed by the elasticated barriers 9, the free edges of which are also located above the absorbent mattress 2, that is to say on the side of its inner face.
On obtient ainsi une couche-culotte qui peut non seulement être fabriquée à un coût réduit mais qui présente en outre des caractéristiques d'étanchéité améliorées. A diaper is thus obtained which can not only be produced at a reduced cost but which also has improved sealing characteristics.
La variante illustrée sur les figures 5 à 7 se différencie de celle des figures 1 à 4 principalement par l'utilisation de barrières d'étanchéité latérales 15 fixées dans leur zone centrale par une zone de collage longitudinale 16 de façon à former de chaque côté de ladite zone centrale une poche d'étanchéité 15a, 15b. La poche d'étanchéité 15b est dirigée vers l'axe longitudinal de la couche-culotte tandis que la poche d'étanchéité 15a est dirigée à l'opposé. Dans ces conditions, chaque barrière d'étanchéité latérale 15 constitue une double poche d'étanchéité munie chaque fois d'au moins un élément élastique 10. The variant illustrated in FIGS. 5 to 7 differs from that of FIGS. 1 to 4 mainly by the use of lateral sealing barriers 15 fixed in their central zone by a longitudinal bonding zone 16 so as to form on each side of said central zone a sealing pocket 15a, 15b. The sealing pocket 15b is directed towards the longitudinal axis of the diaper while the sealing pocket 15a is directed opposite. Under these conditions, each lateral sealing barrier 15 constitutes a double sealing pocket each time provided with at least one elastic element 10.
Les poches l5a et 15b peuvent avoir la même largeur mais de préférence, la poche intérieure 15b peut être moins large que la poche extérieure 15a. Par ailleurs, en fixant plusieurs éléments élastiques sur le bord libre de la poche d'étanchéité 15a, on peut réduire ou supprimer les éléments élastiques 5 sur la feuille imperméable 1.The pockets 15a and 15b can have the same width but preferably, the inner pocket 15b can be less wide than the outer pocket 15a. Furthermore, by fixing several elastic elements to the free edge of the sealing pocket 15a, it is possible to reduce or eliminate the elastic elements 5 on the impermeable sheet 1.
On notera en outre que dans l'exemple illustré, le matelas absorbant 2 est de forme rectangulaire contrairement à la forme en sablier illustré dans la variante de la figure 1. It will also be noted that in the example illustrated, the absorbent mattress 2 is rectangular in shape unlike the hourglass shape illustrated in the variant of FIG. 1.
Bien entendu, toute autre forme de matelas absorbant pourrait être envisagée. Of course, any other form of absorbent mattress could be considered.
Les autres éléments identiques à la variante précédente portent lesmêmes références. The other elements identical to the previous variant bear the same references.
Sur les figures 8 à Il qui illustrent un autre mode de réalisation de l'invention, les parties similaires portent également les mêmes références. In FIGS. 8 to 11 which illustrate another embodiment of the invention, the similar parts also bear the same references.
Dans ce mode de réalisation, la couche-culotte comprend une feuille extérieure imperméable aux liquides 1 réalisée par exemple en polyéthylène, de forme générale rectangulaire et dont les bords longitudinaux ont été repliés en Z le long des bords longitudinaux du matelas absorbant 2 qui présente par exemple une forme générale rectangulaire. Les replis en Z présentent une première partie la sensiblement dans le même plan que la face extérieure du matelas absorbant 2, une partie repliée lb et une partie îc se trouvant sensiblement dans le même plan que la face intérieure du matelas absorbant 2 ou légèrement au-dessus de ladite face comme illustré sur la figure 11. La portion repliée lb est fixée au bord du matelas absorbant 2 sur la feuille intérieure perméable 3. In this embodiment, the diaper comprises an outer liquid-impermeable sheet 1 made for example of polyethylene, of generally rectangular shape and the longitudinal edges of which have been folded in Z along the longitudinal edges of the absorbent mattress 2 which has example a general rectangular shape. The folds in Z have a first part the substantially in the same plane as the outer face of the absorbent mattress 2, a folded part 1b and a part ic lying substantially in the same plane as the inner face of the absorbent mattress 2 or slightly above said face as illustrated in FIG. 11. The folded portion 1b is fixed to the edge of the absorbent mattress 2 on the permeable inner sheet 3.
Des organes élastiques longitudinaux d'entre-jambes 5 ont été fixés à l'état tendu et parallèlement entre eux sur les bords longitudinaux de la feuille extérieure perméable 1 et se situent donc après le repliage en Z de celle-ci, sur la portion repliée îc qui se trouve sensiblement dans le même plan que la face intérieure du matelas absorbant, comme on le voit sur la figure 11. Longitudinal elastic members of the crotch 5 have been fixed in the stretched state and parallel to each other on the longitudinal edges of the permeable outer sheet 1 and are therefore located after the Z-fold thereof, on the folded portion îc which is substantially in the same plane as the inner face of the absorbent mattress, as seen in FIG. 11.
La couche-culotte comporte en outre des barrières latérales d'étanchéité 9 munies, comme précédemment, d'éléments élastiques 10 réalisés sous forme de bandes, par exemple en non-tissé hydrophile ou hydrophobe. Ces bandes sont fixées au moins par leur bord longitudinal extrême opposé à l'axe longitudinal de la couche-culotte sur la portion lc du pli en Z. L'élément élastique 10 est disposé à l'opposé vers l'axe longitudinal de la couche-culotte au-dessus c'est-àdire vers l'intérieur du matelas absorbant 2 de façon à provoquer l'ouverture et le redressement des barrières d'étanchéité 5 formant ainsi des poches d'étanchéité lorsque la couche-culotte est portée par l'utilisateur. The diaper further comprises lateral sealing barriers 9 provided, as previously, with elastic elements 10 produced in the form of strips, for example made of hydrophilic or hydrophobic nonwoven. These bands are fixed at least by their extreme longitudinal edge opposite the longitudinal axis of the diaper on the portion lc of the Z-fold. The elastic element 10 is arranged opposite to the longitudinal axis of the layer -panty above that is to say towards the inside of the absorbent mattress 2 so as to cause the opening and straightening of the sealing barriers 5 thus forming sealing pockets when the diaper is carried by the 'user.
n y a lieu de noter que la fixation des barrières d'étanchéité 9 sur les portions repliées lc de la feuille extérieure imperméable 1 permet d'augmenter l'efficacité des poches d'étanchéité en améliorant le contact de ces éléments avec les cuisses de l'utilisateur de la coucheculotte. It should be noted that the fixing of the sealing barriers 9 on the folded portions lc of the waterproof outer sheet 1 makes it possible to increase the effectiveness of the sealing bags by improving the contact of these elements with the thighs of the user. pantyhose.
La couche-culotte de ce mode de réalisation est également pourvue de barrières d'étanchéité transversales élastifiées 17 placées dans les zones de ceinture de la couche-culotte, c'est-à-dire sur ses parties d'extrémité avant et arrière. Les barrières 17 sont, comme dans le mode de réalisation précédent, de dimensions supérieures en longueur à la largeur transversale de la feuille extérieure imperméable 1 après le repliage en Z de ses bords longitudinaux. La largeur, dans le sens longitudinal de la couche-culotte, des barrières 17 est suffisante pour recouvrir les bords transversaux du matelas absorbant 2. Comme on peut le voir sur la figure 9, les barrières 17 sont fixées sur la feuille intérieure perméable aux liquides 3 ainsi que sur les extrémités longitudinales des barrières d'étanchéité latérales 9 par collage ou tout autre moyen approprié. The diaper of this embodiment is also provided with elasticized transverse sealing barriers 17 placed in the belt areas of the diaper, that is to say on its front and rear end portions. The barriers 17 are, as in the previous embodiment, of dimensions greater in length than the transverse width of the impermeable outer sheet 1 after the Z-folding of its longitudinal edges. The width, in the longitudinal direction of the diaper, of the barriers 17 is sufficient to cover the transverse edges of the absorbent mattress 2. As can be seen in Figure 9, the barriers 17 are fixed on the inner sheet permeable to liquids 3 as well as on the longitudinal ends of the lateral sealing barriers 9 by gluing or any other suitable means.
Les barrières d'étanchéité 17 peuvent être constituées par une bande rectangulaire d'un matériau composite imperméable aux liquides et élastifié sur au moins une partie de sa surface dans le sens transversal de la couche-culotte. Comme on peut le voir sur la figure 9, dans l'exemple illustré, la barrière d'étanchéité 17 comprend successivement depuis l'intérieur vers l'extérieur une bande de nontissé perméable aux liquides 18, un film de polyéthylène 19 et un élément élastique en bande 20. La barrière d'étanchéité 17, située sur la portion arrière de la couche-culotte, est également munie des attaches adhésives 7 pour la fermeture de la couche-culotte. The sealing barriers 17 may consist of a rectangular strip of a composite material impermeable to liquids and elasticized on at least part of its surface in the transverse direction of the diaper. As can be seen in FIG. 9, in the example illustrated, the sealing barrier 17 successively comprises from the inside to the outside a strip of liquid-permeable nonwoven 18, a polyethylene film 19 and an elastic element in a band 20. The sealing barrier 17, located on the rear portion of the diaper, is also provided with adhesive fasteners 7 for closing the diaper.
Dans le mode de réalisation illustré sur les figures 12 à 15 où les éléments similaires portent les mêmes références, la couche-culotte est constituée d'une enveloppe formée par une feuille extérieure imperméable aux liquides 1, par exemple en polyéthylène, dont les bords longitudinaux ont été repliés en Z comme dans le mode de réalisation des figures 8 à 11, présentant comme précédemment les parties la, lb et lc. Le repli en Z forme ici une cuvette adaptée pour recevoir un insert composé par exemple d'un matelas absorbant 2 de forme rectangulaire enveloppé dans un voile perméable aux liquides 3 réalisé par exemple en non-tissé. Des organes élastiques longitudinaux 5 ont été fixés à l'état tendu parallèlement entre eux sur les bords de la feuille extérieure imperméable 1, sur la partie repliée lc, se trouvant sensiblement dans le même plan que la face intérieure du matelas absorbant 2, comme on peut le voir sur la figure 15. Les barrières d'étanchéité latérales 9 ont la même structure et sont disposées de la même manière que dans le mode de réalisation des figures 8 à 11, l'élément élastique 10 provoquant l'ouverture et le redressement des barrières 9 de façon à former des poches d'étanchéité. In the embodiment illustrated in Figures 12 to 15 where similar elements have the same references, the diaper consists of an envelope formed by an outer sheet impermeable to liquids 1, for example of polyethylene, the longitudinal edges were folded in Z as in the embodiment of Figures 8 to 11, showing as before the parts la, lb and lc. The Z-fold forms here a cup adapted to receive an insert composed for example of an absorbent mattress 2 of rectangular shape wrapped in a liquid-permeable veil 3 made for example of nonwoven. Longitudinal elastic members 5 have been fixed in a stretched state parallel to each other on the edges of the impermeable outer sheet 1, on the folded part lc, lying substantially in the same plane as the inner face of the absorbent mattress 2, as can be seen in Figure 15. The lateral sealing barriers 9 have the same structure and are arranged in the same way as in the embodiment of Figures 8 to 11, the elastic element 10 causing the opening and straightening barriers 9 so as to form sealing pockets.
L'enveloppe est également pourvue de barrières transversales d'étanchéité 17 sur ses parties d'extrémité avant et arrière. Ces barrières 17 ont la même structure et sont disposées de la même manière que dans le mode de réalisation des figures 8 à il. Elle sont également fixées à la périphérie de l'enveloppe par collage, thermoscellage ou tout autre moyen approprié. Les barrières d'étanchéité 17 peuvent être constituées en un matériau composite comprenant par exemple successivement depuis l'intérieur vers l'extérieur une bande de non-tissé perméable aux liquides 18 et un film de polyéthylène imperméable 19. The envelope is also provided with transverse sealing barriers 17 on its front and rear end parts. These barriers 17 have the same structure and are arranged in the same manner as in the embodiment of Figures 8 to it. They are also fixed to the periphery of the envelope by gluing, heat sealing or any other suitable means. The sealing barriers 17 can be made of a composite material comprising, for example successively from the inside to the outside, a strip of liquid-permeable nonwoven 18 and a film of impermeable polyethylene 19.
Dans l'exemple illustré aucun élément élastique de ceinture n'est prévu bien que celui-ci puisse être adjoint. In the example illustrated, no elastic belt element is provided, although the latter may be added.
On obtient ainsi une couche-culotte sous la forme d'une enveloppe réutilisable qui peut facilement être pourvue d'un élément absorbant jetable. Celui-ci peut également être muni d'éléments de fixation du type auto-adhésif non illustré sur la figure, afin de renforcer son maintien à l'intérieur de l'enveloppe. A diaper is thus obtained in the form of a reusable envelope which can easily be provided with a disposable absorbent element. The latter may also be provided with fixing elements of the self-adhesive type not illustrated in the figure, in order to reinforce its retention inside the envelope.
Comme dans les modes de réalisation précédents, on obtient à la fois une excellente étanchéité transversale notamment dans la zone d'entre-jambes ainsi qu'une bonne étanchéité longitudinale dans la zone de ceinture, tout en permettant une diminution notable des coûts de fabrication, grâce aux économies substantielles de matières premières notamment de polyéthylène et de non-tissé réalisées dans la zone de l'entrejambes par rapport à une méthode de fabrication de type classique. As in the previous embodiments, both excellent transverse tightness is obtained in particular in the crotch area as well as good longitudinal tightness in the belt area, while allowing a significant reduction in manufacturing costs, thanks to the substantial savings in raw materials, in particular polyethylene and nonwoven, made in the crotch area compared to a conventional type of manufacturing method.
