Description
* * * . Serviette hygiénique comportant un écran incorporé.
La présente invention a pour objet une serviette hygiénique et notamment une serviette hygiénique comportant une partie absorbante repliée à plusieurs couches.
5 On a constaté récemment que les serviettes hygié niques munies de couches absorbantes contenant une matière ' thermoplastique présentent certains avantages vis-à-vis des serviettes hygiéniques qui n'utilisent en tant qu'élément absorbant qu'une matière cellulosique classique. La pré-10 *· sence de la matière thermoplastique ajoute de l'élasticité à l'élément absorbant et tend également à éviter l'affaissement des conduits capillaires de la matière cellulosique lorsque les deux matières sont mélangées. Comme exemples de brevets étudiant l'utilisation de matière thermoplasti-15 que en liaison avec une matière cellulosique pour des ar ticles sanitaires, on peut citer : les brevets des E.U.A. n°4.082.886 et 4.129.132 délivrés à George A.M. Butter-worth et associés, n°3.976.074 délivré à Harry G. Fitzgerald et associés, n°4.054.141 délivré à Julius Schwaiger 20 et associés, n°4.047.531 délivré à Hamzeh Karami,n°3.545.441 délivré à Gunnar Gravdall et n°4.219.024 délivré, à Donald Patience et associés.
Les brevets ci-dessus décrivent également l'agen-cernent de serviettes hygiéniques avec des éléments absor-25 bants à plusieurs couches.
Il a été établi récemment que les serviettes hy-giéniques comportant des éléments absorbants à plusieurs couches dans lesquels les couches sont façonnées par'pliage procurent un confort accru non seulement dans les zones 30 pliées, mais aussi par accroissement de la résistance aux déformations permanentes et de l'élasticité. Ces caractéristiques se manifestent de façon particulièrement forte si des fibres thermoplastiques sont utilisées dans l'ensemble de la garniture absorbante repliée. Lorsqu'il y a des fibres 35 » thermoplastiques, la résistance aux déformations oermanentes
A
« » . - 2 - » ! par compression est accrue à cause de la présence de chaque pli individuel. Compte tenu de ce qui précède, il est clair qu'une serviette hygiénique comportant une garniture absorbante avec des fibres thermoplastiques repliée plusieurs 5 fois sur elle-même doit être notablement plus confortable qu'une serviette hygiénique ne présentant pas cette caractéristique.
Cependant, lorsqu'on utilise des fibres thermoplastiques, il se produit généralement une diminution de la ca-10 pacité globale d'absorption, en particulier si les fibres * sont présentes en quantités suffisantes pour donner une élasticité accrue.
L'invention a pour but d'éviter cet inconvénient et concerne à cet effet une serviette hygiénique du type 15 ci-dessus caractérisé en ce qu'elle comporte une garniture absorbante repliée vers l'intérieur le long de chaque bord longitudinal puis repliée à nouveau pour constituer trois couches absorbantes distinctes, une enveloppe perméable aux fluides étant disposée sur la partie supérieure de la gar-20 niture absorbante qui constitue la première couche et passant sur les parties repliées de l'ensemble à plusieurs couches formé avec la garniture absorbante. La serviette hygiénique conforme à l'invention utilise un écran imperméable aux fluides dans toutes les zones situées entre la garniture 25 absorbante et l'enveloppe à l'exception de la partie de la serviette hygiénique prévue pour venir contre le corps de la personne qui la porte.
On va maintenant décrire l'invention plus en détail ry en se référant aux dessins annexés, dans lesquels : 30 - -la Fig.l est une vue en perspective et en coupe partielle d'une serviette hygiénique conforme à l'invention; - la Fig.2 est une vue en coupe transversale suivant la
-V
ligne 2 - 2 de la Fig.l.
La serviette hygiénique représentée sur les figures 35 1 et 2 comporte une première garniture absorbante 14 compre- /nant une couche absorbante supérieure 14a, une seconde couche « - 3 - » absorbante 14b constituée par deux ailes de matière iden-» tiques formées par pliage suivant les plis 14a' parallèle ment à l'axe longitudinal. Une troisième couche absorbante 14c présente deux ailes distinctes qui s'étendent sur les 5 ailes de la couche 14b à la suite du pliage représenté en 14b' .
La garniture absorbante 14 contient une matière thermoplastique qui donne une élasticité accrue par suite de la présence des couches multiples formées par les plis 10 14a' et 14t»'.Le pourcentage de matière thermoplastique peut varier n'importe où dans cette couche de 10 à 100%.
Dans l'exemple de réalisation particulier représenté sur la Fig.l et la Fig.2, il est prévu une couche absorbante intermédiaire 15. Cette couche absorbante par-15 ticulière est conçue pour avoir une capacité accrue par rapport à celle qu'on aurait avec la garniture absorbante 14. En raison du niveau d'élasticité particulièrement élevé dû à la garniture absorbante 14, on n'a pas à prévoir une élasticité importante pour la couche intermédiaire 15. La 20 couche 15 peut être réalisée en une matière absorbante constituée par l'une quelconque de plusieurs matières absorbantes de capacité relativement élevée telles que la bourre de pâte à papier ou une matière hautement absorbante. Une matière d'utilisation particulièrement préférentielle 25 est la matière décrite dans le brevet des E.U.A. n°4.372.312.
Il s'agit d'une feuille de microfibres soufflées à l'état fondu et traitées par un agent tensio-actif. Cette feuille particulière est caractérisée par une capacité élevée d'absorption des fluides et peut être utilisée seule ou 30 en combinaison avec de la bourre de pâte à papier hautement absorbante ou une matière similaire.
Conformément à la Fig.l, l'enveloppe 10 recouvre la couche 14a de la garniture 14 et s'étend autour de chaque · pli 14a'.L'enveloppe 10 passe en outre sur la partie exté-35 rieure, c'est-à-dire la partie inférieure de chacune des ailes qui forment la couche 14b, sur chaque élément replié 14c et se termine sur les extrémités intérieures de la I couche 14c.

Un écran intérieur 22 est disposé entre l'enveloppe 1 10 et la couche absorbante 14, à l'exception de la surface supérieure du tampon, au moins dans une zone correspondant à la région périnéale cfela personne gui porte la serviette.
5 L'écran intérieur ou écran incorporé 22 détermine des par cours d'écoulement de fluides le long des côtés de la garniture 14 pour réduire le plus possible les fluides ayant lieu à partir de cette garniture. Cet écran sert aussi à former de parcours de retenue pour les fluides gui sont 10 captés, mais non retenus, par la couche 15.
* L'écran peut être constitué en une matière ther- moplastique classique quelconque connue dans la technique et sa composition particulière ne fait pas l'objet de l'invention. Comme représenté sur la Fig.l et la Fig.2, la 15 matière de l'enveloppe 10 peut être liée aux couches 14 aux emplacements 11 par liaison de fusion par ultrasons ou par un procédé similaire pour accroître la capacité de passage des fluides à travers la couche absorbante 14a.
L'exemple de réalisation représenté sur la Fig.l 20 et la Fig.2 comporte un second écran 16 ajouté pour accroî tre la stabilité de la structure de la serviette hygiénique suivant cet exemple de réalisation préférentiel de l'invention. Comme on le voit clairement sur la Fig.2, l'écran 16 présente trois lignes adhésives 17 fixées sur lui et 25 une doublure amovible pour l'adhésif des lignes 17. La serviette hygiénique est scellée de façon classique à chaque extrémité par des moyens à ultra-sons. Les zones de , scellement sont représentées comme dégagées sur la matière 12 de l'enveloppe thermoplastique. Ces zones forment des 30 ' pattes d'extrémité libres 13.
Une serviette hygiénique constituée conformément à l'invention est fabriquée de préférence en formant conjointement par extrusion localisée l'écran en matière thermoplastique sur une enveloppe non tissée. Un tel pro-35 cédé est décrit, par exemple, dans le brevet des E.U.A.
/n°3.356.556 et ne fait pas l'objet de la présente invention.
- 5 - « * L'écran peut bien entendu être découpé en bandes * et fixé par adhésif ou lié séparément par fusion, suivant des variantes de procédé. La garniture 14 est alors positionnée de façon appropriée sur l'ensemble formé par l'é-5 cran et l'enveloppe et le tout est replié deux fois le long de chaque bord de l'ensemble pour constituer la structure conforme à l'invention précédemment décrite. Si l'on doit utiliser une ou plusieurs couches absorbantes supplémentaires 15, ces couches sont bien entendu positionnées pendant 10 l'étape de pliage.
