Description

Die Erfindung betrifft eine Wegwerfwindel gemäß Oberbegriff des Patentanspruchs I.The invention relates to a disposable diaper according to the preamble of claim I.

Eine derartige Windel ist aus der DE-Gebrauchsmusterschrift 17 98 202 bekannt, bei der s-vischen einer Innenschicht und einer Außenschicht eine saugfähige Zellstoffmatte liegt und wobei außerdem zwischen der Zellstoffmatte und der Innenschicht eine Puderschicht vorgesehen ist. Ein Nachteil der bekannten Windel besteht darin, daß sie als endlose Rolle ohne geschlossene Seitenwände geliefert wird, wodurch die Puderschichi seitlich aus der Winde! austreten und verlorengehen kann. Ein weiterer Nachteil besteht darin, daß in der Innenschicht keine Öffnungen für den Austritt von Puder vorgesehen sind.Such a diaper is from the DE utility model 17 98 202 known, with the s-vischen an inner layer and an outer layer is an absorbent pulp mat and wherein further between the pulp mat and the inner layer is provided with a powder layer. There is a disadvantage of the known diaper in that it is supplied as an endless roll without closed side walls, whereby the powder layer is sideways out of the wind! leak and get lost. Another disadvantage is that in the inner layer no openings are provided for the powder to escape.

Aus der DE-OS 21 46 278 ist ferner eine als Windei verwendbare saugfähige Vorlage bekannt, die zwischen einer Innenschichi und einer Außenschicht einen saugfähigen Grundkörper aufweist, wobei die Innenschicht mit Schlitzen für den Eintritt von Körperflüssigkeit versehen ist. In einer Ausführung soll die Vorlage an der Außenseite der Innenychicht mit Puder oder Hautwasser bedeckt sein. Eine derartige Windel kann nur eine geringe Menge von Puder an der Außenseite der Innenschicht halten. Der größte Teil dieser Puderschicht geht außerdem beim erstmaligen Handhaben der Windel verloren und bewirkt eine unerwünschte Verunreinigung der Windelunterlage.From DE-OS 21 46 278 is also a Windei usable absorbent template known that between an inner layer and an outer layer an absorbent Has base body, the inner layer being provided with slots for the entry of body fluid is. In one embodiment, the template is to be applied to the outside of the interior layer with powder or skin water be covered. Such a diaper can only have a small amount of powder on the outside of the inner layer keep. Most of this powder layer also goes when the diaper is first handled lost and causes undesirable contamination of the diaper pad.

Es sind auch schon Wegwerfwindeln mit einer Schicht aus absorbierendem Material und mit darin eingekapseltem Babyöl bekannt (US-PS 35 85 998). Diese Windeln sind aber aufwendig in der Herstellung.There are also disposable diapers with a layer of absorbent material and encapsulated therein Baby oil known (US-PS 35 85 998). However, these diapers are expensive to manufacture.

Es ist demgegenüber Aufgabe der Erfindung, eine Wegwerfwindel zu schaffen, die mit einer Puderschicht versehen ist und bei der diese Puderschicht nicht in unerwünschter Weise beschädigt werden oder verlorengehen kann.In contrast, the object of the invention is to provide a disposable diaper that has a powder layer is provided and in which this powder layer is not undesirably damaged or lost can.

Zur Lösung dieser Aufgabe dienen bei einer Windel der eingangs genannten Art, die im Kennzeichen desTo solve this problem are used in a diaper of the type mentioned, which in the identifier of the

Patentanspruchs 1 angegebenen Merkmale.Claim 1 specified features.

Dadurch wird eine Wegwerfwindel geschaffen, die einfach im Aufbau und in der Herstellung ist und die dem Betreuer eines Kleinkindes der Notwendigkeit entheben, beim Reisen mit dem Säugling oder Kleinkind platzraubende Puderdosen oder ähnliches Zubehör mitzuführen. This creates a disposable diaper which is simple in construction and manufacture and which Eliminate the need for an infant caregiver when traveling with the infant or toddler carry space-consuming powder compacts or similar accessories.

Bevorzugte- Ausführungsformen sind in den ■Unteransprüchen 2 und 3 beschrieben, für weiche nur in Verbindung mit dem Hauptanspruch Schutz begehrt wird.Preferred embodiments are set out in the subclaims 2 and 3, for which protection is sought only in connection with the main claim.

Die Erfindung wird im folgenden anhand von Zeichnungen näher erläutert. Es zeigtThe invention is explained in more detail below with reference to drawings. It shows

F i g. 1 in auseinandergezogener perspektivischer Darstellung die erfindungsgemäße puderhaltige Windel F i g. 1 shows the powder-containing diaper according to the invention in an exploded perspective view

Fi g. 2 einen Querschnitt entlang der Ebene der Linie 2-2in Fig. 1.Fi g. Figure 2 is a cross-section along the plane of the line 2-2 in Fig. 1.

Die puderhaltige erfindungsgemäße Wegwerfwindel 10 besteht im wesentlichen aus vier Bestandteilen, näm Hch einer äußeren Schicht 12, einer Mittelschicht 14. einer Puderschicht 16 und einer inneren Schicht !S.The powder-containing disposable diaper 10 according to the invention consists essentially of four components, namely With an outer layer 12, a middle layer 14, a powder layer 16 and an inner layer!

Die äußere Schicht 12 besteht aus einem geeigneten wasserfesten, nicht absorbierenden und flüssigkeitsundurchlässigen Material, um ein Durchdringen von Flüssigkeit durch die gesamte Windel zu verhindern. Vorzugsweise besteht die Schicht 12 aus einer Polyäthylenfolie. The outer layer 12 is made of a suitable waterproof, non-absorbent and liquid-impermeable Material to prevent liquid from penetrating the entire diaper. Preferably the layer 12 consists of a polyethylene film.

Die absorbierende Mittelschicht 14 wird aus einer weichen, stark absorbierenden Zellstofflage 20 hergestellt, die in der An eines Sandwichs zwischen zwei dünnen adsorbierenden Lagen oder Geweben 22 und 24 liegt. Oben auf der absorbierenden Mittelschicht 14 ist eine ausreichende Menge Puder gleichmäßig in Form einer Schicht 16 verteilt. Die innere Schicht 18 besteht aus einem nicht absorbierenden, weichen, nicht gewebten Material mit einer großen Anzahl kleiner Öffnungen 26. Die Schicht 18 erlaubt das Austreten von Flüssigkeit in das Mittelstück der Windel und ebenfalls das Durchtreten von Puder auf die Oberfläche d..:r Windel, so daß sich bei dem Kind stets ein »trockenes Gefühl« ergibt.The absorbent middle layer 14 is made of a soft, highly absorbent cellulose layer 20, the kind of sandwich between two thin absorbent sheets or fabrics 22 and 24 lies. On top of the absorbent middle layer 14 is a sufficient amount of powder evenly distributed in the form of a layer 16. The inner layer 18 is made made of a non-absorbent, soft, non-woven material with a large number of small openings 26. The layer 18 allows liquid to escape into and also pass through the center of the diaper of powder on the surface of the diaper, so that the child always has a "dry feeling".

Um ein sachgerechtes Funktionieren der Windei zu ermöglichen, wird die innere Schicht 18 straff über die Puderschicht gespannt, so daß die Puderschicht 16 dadurch verfestigt wird. Dies läßt sich dadurch erreichen.To ensure proper functioning of the diaper allow, the inner layer 18 is stretched taut over the powder layer, so that the powder layer 16 thereby is solidified. This can be achieved thereby.

daß die Zellstofflage 20 im Mittelteil geringfügig stärker ausgelegt wird, so daß sie an c! η kritischen Stellen mehr adsorbiert und die Gesamtwindel gleichzeitig an den äußeren Enden flexibler wird. Durch das Strammziehen der inneren Schicht 18 beim Verbinden mit den anderenthat the cellulose layer 20 is designed slightly stronger in the middle part, so that it is at c! η more critical points adsorbed and the overall diaper is at the same time more flexible at the outer ends. By pulling it tight of the inner layer 18 when joining with the others

so Schichten durch beispielsweise Nähen oder Kleben wird eine wirksame Verfestigung der Puderschicht erreicht. Die puderhaltigen Windeln können in üblicher Weise verpackt und gehandhabt werden, ohne daß ein Puderverlust zu befürchten ist. Wenn die Windel dem Baby angelegt wird, wird die Straffheit der inneren Schicht 18 gelöst, so daß das Puder sich selbst auf die Haut des Babys aufträgt und dadurch die häufig gefährliche Anwendung von Puderdosen nicht mehr erforderlich ist, bei der Puder versehentlich verschüttet wird und dann gegebenenfalls in die Atemwege des Kindes eindringen kann.an effective solidification of the powder layer is achieved in this way, for example by sewing or gluing. The powder-containing diapers can be packaged and handled in the usual way without a Powder loss is to be feared. When the diaper is put on the baby, the tightness becomes the inner one Layer 18 dissolved, so that the powder applies itself to the baby's skin and thus the often dangerous Use of powder compacts is no longer necessary when powder is accidentally spilled and can then possibly enter the child's airways.
