Wegwerf-Hygieneartikel nach Ansprüchen 1-4, dadurch gekennzeichnet, dass die Unterlagenfolie eine nicht-perforierte Kunststoffolie ist.5. disposable hygiene article according to claims 1-4, characterized in that the base film is a non-perforated plastic film. Die vorliegende Erfindung betrifft einen Wegwerf-Hygie-neartikel. Bei Windeln, Monatsbinden u.dgl., die mit einer nassfesten hydrophoben textilen Einlage versehen sind, besteht die Forderung, dass das Rücknässen von Flüssigkeit verhindert ist und die Gestalt des saugfähigen Polsters erhalten bleibt.The present invention relates to a disposable hygiene article. In the case of diapers, sanitary napkins and the like that are provided with a wet-resistant hydrophobic textile insert, there is a requirement that liquid is prevented from rewetting and that the shape of the absorbent padding is retained. Wegwerf-Windeln mit einem saugfähigen Polster, das aus einem Kern aus Holzflocken oder ähnlichem Material gebildet wird, sind gut bekannt. Die Polster in diesen bekannten Wegwerf-Windeln sind versehen und werden zusammen gebraucht mit einer feinen Gewebeeinlage, die aus einem stark flüssigkeitsdurchlässigen und aufsaugenden Material besteht. Die Einlagen werden in den bekannten Hygieneartikeln zwar zum Einhüllen der saugfähigen Polster verwendet, verlieren jedoch ihre Festigkeit, wenn sie nass werden, so dass die Polster beim Gebrauch häufig ihre Form und ihre Absorptionsqualität verlieren und in unerwünschtem Masse ein Rücknässen von Flüssigkeit zulassen.Disposable diapers having an absorbent pad formed from a core of wood fluff or similar material are well known. The pads in these known disposable diapers are provided and used together with a fine fabric pad made of a highly liquid permeable and absorbent material. Although the inserts are used in the known hygiene articles to envelop the absorbent pads, they lose their strength when they become wet, so that the pads often lose their shape and their absorption quality during use and allow an undesirable degree of liquid rewetting. Es wurden bereits Versuche unternommen mit dem Ziel, das Rücknässen von Flüssigkeit einzudämmen, beispielsweise durch eine Sperrschicht, wie sie in US-PS 3 987 792 (J.M. Hernandez) für Wegwerf-Windeln mit einer verbesserten Flüssigkeitsretention beschrieben werden. Die hydrophoben Fasern dieser bekannten Sperrschicht bilden jedoch ein relativ dickes elastisches Faserpolster, das nur schwierig von Flüssigkeit durchdrungen werden kann, weshalb man eine wasserdurchlässige Oberschicht vorsehen muss, die mit Öffnungen für die aufzunehmende Flüssigkeit versehen ist.Attempts have been made to control liquid rewet, for example by using a barrier layer such as that disclosed in U.S. Patent 3,987,792 (J.M. Hernandez) for disposable diapers having improved liquid retention. However, the hydrophobic fibers of this known barrier layer form a relatively thick, elastic fiber padding through which liquid can only be penetrated with difficulty, which is why a water-permeable top layer must be provided which is provided with openings for the liquid to be absorbed. Der vorliegenden Erfindung liegt die Aufgabe zugrunde, die vorstehend beschriebenen Schwierigkeiten möglichst weitgehend zu vermeiden und Wegwerf-Hygieneartikel zu schaffen, bei denen im Gebrauch die Form des saugfähigen Polsters erhalten bleibt und die in hohem Masse das Rücknässen von Flüssigkeit ausschliessen.The object of the present invention is to avoid the above-described difficulties as far as possible and to provide disposable hygiene articles in which the shape of the absorbent pad is retained during use and which to a large extent prevent liquid from rewetting. Diese Aufgabe wird erfindungsgemäss durch einen Weg-werf-Hygieneartikel mit den Merkmalen des Patentanspruchs 1 gelöst. Die textile Einlage umhüllt vorzugsweise das saugfähige Polster, so dass die hydrophobe textile Einlage selbst, nachdem Flüssigkeit durch sie hindurch in das saugfähige Polster eingedrungen ist, praktisch ihre volle Festigkeit beibehält. Zusammen mit der Oberflächenschicht verhindert sie vorteilhaft das Rücknässen von Flüssigkeit und kann auf diese Weise dafür sorgen, dass die Haut desAccording to the invention, this object is achieved by a disposable hygiene article having the features of patent claim 1 . The textile pad preferably encapsulates the absorbent pad so that the hydrophobic textile pad retains substantially all of its strength even after liquid has penetrated through it into the absorbent pad. Together with the surface layer, it advantageously prevents liquid from rewetting and can in this way ensure that the skin of the Benutzers mit einer trockenen Oberfläche in Berührung bleibt.user remains in contact with a dry surface. Durch die erfindungsgemässe Anordnung von zwei dünnen Schichten aus hydrophobem Vliesmaterial kann das Rücknässen von Flüssigkeit deutlich vermindert werden, so dass man z. B. ein Kleinkind bei der Verwendung einer erfin-dungsgemässen Wegwerf-Windel wesentlich leichter trok-ken- halten kann.The arrangement according to the invention of two thin layers of hydrophobic fleece material can significantly reduce liquid rewetting, so that z. B. a small child can be kept dry much more easily when using a disposable diaper according to the invention. Ein weiterer Vorteil der Erfindung kann darin bestehen, dass die aufgebauten Wegwerf-Hygieneartikel, z.B. Weg-werf-Windeln, den hohen Grad von Rücknässungshemmung ohne eine dicke Hemmschicht erreichen, so dass man eine maximale Menge an saugfähigem Polstermaterial vorsehen und dennoch Volumen und Grösse der Windel im erwünschten Ausmass begrenzen kann.A further advantage of the invention may be that the constructed disposable personal care articles, e.g. disposable diapers, achieve the high level of rewet inhibition without a thick inhibition layer, so that one can provide a maximum amount of absorbent cushioning material and still maintain the volume and size of the diaper to the desired extent. Die Erfindung wird nachfolgend anhand von in den Figuren dargestellten Ausführungsformen weiter erläutert.The invention is explained in more detail below with reference to the embodiments shown in the figures. Fig. 1 zeigt eine perspektivische Darstellung einer Windel, die gemäss der Erfindung aufgebaut ist und durch teilweisen Aufbruch Einzelheiten des Aufbaues erkennen lässt.1 shows a perspective view of a diaper constructed in accordance with the invention and showing details of the construction by partially breaking away. Fig. 2 stellt einen vertikalen Schnitt dar, der entlang der Linie 2-2 in Fig. 1 gelegt wurde.FIG. 2 is a vertical section taken along line 2-2 of FIG. 1. FIG. Fig. 3 stellt einen ähnlichen Schnitt wie in Fig. 2 dar,Fig. 3 shows a similar section as in Fig. 2, zeigt jedoch eine bevorzugte Ausführungsform der Erfindung mit einer textilen Einlage, die das Polster umhüllt.however, shows a preferred embodiment of the invention with a textile insert encasing the cushion. Als Beispiel für eine Ausführungsform eines Wegwerf-Hygieneartikels ist in Fig. 1 eine Wegwerf-Windel 10 dargestellt, die, in der angegebenen Reihenfolge, zunächst eine Oberfiächenschicht 12 aufweist, die aus hydrophoben Vliesfasern aus Polyethylen und/oder Polypropylen besteht. Diese Schicht ist wasserdurchlässig, absorbiert jedoch kein Wasser und lässt Abfallflüssigkeit zum saugfähigen Polster 14 passieren, wobei letzteres von der Oberflächenschicht 12 durch eine feine textile Einlage 16 aus hydrophoben Vliesfasern, vorzugsweise aus Polyethylen und/oder Polypropylen, getrennt ist.As an example of an embodiment of a disposable hygiene article, FIG. 1 shows a disposable diaper 10 which, in the order given, first has a surface layer 12 consisting of hydrophobic nonwoven fibers made of polyethylene and/or polypropylene. This layer is water permeable but does not absorb water and allows waste liquid to pass to the absorbent pad 14, the latter being separated from the surface layer 12 by a fine textile pad 16 of hydrophobic non-woven fibers, preferably of polyethylene and/or polypropylene. Eine weitere Einlage 18 Hegt unter über dem Polster und auf einer wasserundurchlässigen Unterlagenfoüe 20 aus geeignetem Kunststoff, z.B. einem Polyethylenfilm. Die Unterlagenfolie 20 ist bei 22 um die Oberflächenfolie 12 gefaltet und stellt auf diese Weise sicher, dass die Windel in dem zusammengesetzten Zustand erhalten bleibt. Klebstoffe, Heiss-siegelung, Prägung oder andere Mittel können zur Befestigung des Aufbaues verwendet werden. Der Kern 14 besteht vorzugsweise aus Holzflocken oder aus Gewebeschichten aus papierähnlichem Material mit hoher Saugfähigkeit. Unter Beanspruchung wied dieses Material leicht verzerrt. Um die Gestalt des Polsters zu sichern, kann anstelle der Einlage 16 und 18 eine Gewebeeinlage 26 um das Polster 14 gehüllt werden.A further pad 18 underlies the pad and rests on a water impervious backing sheet 20 of suitable plastic such as polyethylene film. The backsheet sheet 20 is folded at 22 about the top sheet 12, thus ensuring that the diaper remains in the assembled condition. Adhesives, heat sealing, embossing or other means can be used to attach the assembly. The core 14 is preferably made of wood flakes or tissue layers of paper-like material with high absorbency. This material is easily distorted under stress. To secure the shape of the pad, a fabric pad 26 may be wrapped around pad 14 in place of pads 16 and 18. Die einhüllende Einlage 26 hält die Gestalt des Polsters aufrecht, da es sich hierbei um eine hochfeste Umhüllung handelt, die wegen ihres hydrophoben Charakters eine hohe Wasserfestigkeit besitzt und tatsächlich keine Flüssigkeit absorbiert, so dass sie durch den Flüssigkeitsdurchgang in ihrer Festigkeit nicht geschwächt wird. Obwohl das hydrophobe Material der textilen Einlage leicht Flüssigkeit in das Polster 14 durchlässt, ist es in Verbindung mit der hydrophoben Oberflächenschicht 12 in hohem Masse widerstandsfähig gegen Flüssigkeitsrücknässung. Dies erklärt sich daraus, dass die Schicht, anders als die Gewebeeinlagen bekannter Hygieneartikel, keine Flüssigkeit absorbiert.The enveloping pad 26 maintains the shape of the pad because it is a high strength wrapper which, because of its hydrophobic character, has high water resistance and does not actually absorb liquid, so it is not weakened in strength by liquid passage. Although the hydrophobic material of the textile insert readily transmits liquid into the pad 14, in combination with the hydrophobic surface layer 12 it is highly resistant to liquid rewet. This can be explained by the fact that the layer, unlike the fabric inserts of known hygiene articles, does not absorb any liquid. Selbstverständlich können auch Abweichungen von den oben beschriebenen Ausführungsformen des erfindungsge-mässen Wegwerf-Hygieneartikels vorgenommen werden, die ebenfalls unter den Umfang der vorliegenden Erfindung fallen.Deviations from the above-described embodiments of the disposable hygiene article according to the invention can of course also be made, which also fall within the scope of the present invention. 22 55 1010 1515 2020 2525 3030 3535 4040 4545 5050 5555 6060 6565 SS 1 Blatt Zeichnungen1 sheet of drawings
