Description

Die Erfindung betrifft eine Wegwerfwindel gemäß Oberbegriff des Patentanspruchs 1.The invention relates to a disposable diaper according to the preamble of claim 1.
Aus der DE-OS 23 19 541 ist eine Wegwerfwindel dieser Art mit einer im Schrittbereich angeordneten Kellerfalte bekannt, deren Faltungen durch innen angeordnete Klebepunkte gehalten werden. Diese sollen ein Entfalten im Schrittbereich verhindern, wenn die Windel zum Anlegen auseinandergezogen wird. Dabei besteht jedoch der Nachteil, daß beim Auseinanderziehen der Windel auch die Faltung bis zu den Klebepunkten auseinandergezogen wird, die dabei sehr leicht aufreißen können, weil die Zugkräfte sehr ungünstig einwirken. From DE-OS 23 19 541 a disposable diaper is this Type known with a box pleat arranged in the crotch area, the folds of which by arranged inside Adhesive dots are held. These are intended to prevent the crotch area from unfolding when the diaper is pulled apart to put on. However, there is the disadvantage that when pulling apart The diaper also pulls the fold apart up to the glue points, which tear open very easily because the tensile forces act very unfavorably.
Aufgabe der Erfindung ist es, diese Nachteile zu beseitigen und eine Windel von vereinfachter Konstruktion zu schaffen, die sich gut an den Kinderkörper anpaßt. The object of the invention is to obviate these drawbacks and to provide a diaper of simplified construction to create that adapts well to the child's body.
Zur Lösung dieser Aufgabe dienen die Merkmale des Patentanspruchs 1.The features of claim 1 serve to solve this problem.
Durch den auf der Außenseite der Windel angebrachten Klebstreifen wird mit Sicherheit vermieden, daß sich die Windel im Schrittbereich entfaltet; sie bleibt vielmehr flach und ist angenehm zu tragen, wodurch sie sich dichtend an den Kinderkörper anlegt.The adhesive tape attached to the outside of the diaper is sure to avoid that the diaper unfolds in the crotch area; Rather, it stays flat and is comfortable to wear, which makes it stand out sealingly applied to the child's body.
Aus der FR-PS 10 16 486 ist zwar bereits eine keller- bo faltenartig zusammengelegte Windel bekannt, die jedoch keine saugfähige Einlage aufweist. Die Kellerfalte ist bei ihr durch eine Längsnaht fixiert, was für eine Windel ohne saugfähige Einlage wirtschaftlich sein mag, für eine Wegwerfwindel der eingangs genannten Art jedoch völlig ungeeignet ist.From FR-PS 10 16 486 there is already a keller-bo Known fold-like folded diaper, which, however, does not have an absorbent insert. The box fold is fixed by a longitudinal seam, which may be economical for a diaper without an absorbent insert, is completely unsuitable for a disposable diaper of the type mentioned.
Im folgenden wird die Erfindung anhand der Figuren näher erläutert; es zeigtIn the following the invention is based on the figures explained in more detail; it shows

Fig.2 einen Querschnitt durch den Schrittbereich der Windel.2 shows a cross section through the crotch area the diaper.
Die Windel 10 besteht aus einer flüssigkeitsdurchlässigen Außenschicht 14 aus Kunststuff, einer Innenschicht 16 und einer dazwischenliegenden saugfähigen Lage 12, die beispielsweise ein bekanntes flauschartiges Material wie Zellstoff oder Watte sein kann. Sie weist eine in Längsrichtung verlaufende Faltung 18 auf, deren innenseite die Außenschicht 14 bildet. Die in Längsrichtung verlaufenden Faltungen 20 und 22 liegen im wesentlichen in der Mitte zwischen der Längsachse und den zugehörigen Seitenrändern 24 bzw. 26 der Windel. Ds beiden Faltungen 20 und 22 sind entgegengesetzt zur Faltung 18 gefaltet, ihre Innenseite bildet die Innenschicht 16. in der Mitte des Schrittbereiches sind die Faltungen 20 bzw. 22 zusammengezogen, um die Windel an dieser Stelle einzuschnüren oder zu verjüngen. Dies wird dadurch erreicht, daß ein anschließend an die FaI-rimer OO liAnon/ior floratnU At** A ,,flnnrnU^U* \Λ m;» n; The diaper 10 consists of a liquid-permeable outer layer 14 made of synthetic material, an inner layer 16 and an absorbent layer 12 in between, which can be, for example, a known fluff-like material such as cellulose or wadding. It has a fold 18 running in the longitudinal direction, the inside of which forms the outer layer 14. The longitudinal folds 20 and 22 lie substantially midway between the longitudinal axis and the associated side edges 24 and 26 of the diaper, respectively. The two folds 20 and 22 are folded opposite to the fold 18, their inside forms the inner layer 16. In the middle of the crotch region the folds 20 and 22 are drawn together in order to constrict or taper the diaper at this point. This is achieved in that a subsequent to the FaI- rimer OO liAnon / ior floratnU At ** A ,, flnnrnU ^ U * \ Λ m ; » n ;

Fig.2 zeigt einen Klebstreifen 28, der über einen anschließend an die Faltungen 20 bzw. 22 liegenden Bereich der Außenschicht 14 geklebt ist, um die Faltungen 20 bzw. 22 im Schrittbereich im wesentlichen aneinanderstoßen zu lassen. Es können auch Bereiche der Innenschicht 16 im Schrittbereich mittels Klebeflächen 30 aneinander festgemacht sein. Eine auf diese Weise gebildete schwalbenschwanzförmige Faltung wird als Kellerfalte bezeichnet. Die Faltungen 20 bzw. 22 bilden dabei die Brüche der Kellerfalte aus. - ~ ·· Ο - "" W 0 W,. * .-! ,, WWl WIWIl WWl riuUkllJt.1111.111 IT HUt. Cl "is firmly connected to a corresponding area adjacent to the fold 22. FIG. 2 shows an adhesive strip 28 which is glued around the folds 20 and 22 over an area of the outer layer 14 that is adjacent to the folds 20 and 22, respectively Areas of the inner layer 16 in the crotch area can also be fastened to one another by means of adhesive surfaces 30. A dovetail fold formed in this way is referred to as a box fold.
Im angelegten Zustand der Windel können die Hüftbereiche 32 bzw. 34 auseinandergezogen werden, wobei die in Längsrichtung verlaufende Kellerfalte und der Klebstreifen 28 ein Verjüngen der Windel im Schrittbereich, sowie das Vorhandensein mehrerer Schichten von saugfähigen Lagen 12 bewirken. Die Klebeflächen 30 halten den Mittelbereich 36 der Kellerfalte nieder.When the diaper is put on, the hip areas 32 and 34 can be pulled apart, with the longitudinal box pleat and the adhesive strip 28 taper the diaper in the crotch area, as well as the presence of multiple layers of absorbent sheets 12. The adhesive surfaces 30 hold down the central area 36 of the box fold.
Anstelle des Klebstreifens 28 können selbstverständlich andere Befestigungsmittel Verwendung finden. Es können auch verschiedene Verjüngungen und Saugiähigkeitskapazitäten durch Veränderung der seitlichen Lage der Faltungen 20 und 22 im Schrittbereich, sowie auch durch Veränderung des Abstandes der zusammengehaltenen Faltungen 20 und 22 erzielt werden.Instead of the adhesive strip 28, other fastening means can of course be used. It can also have different tapers and suction capacities by changing the lateral position of the folds 20 and 22 in the crotch area, as well as can also be achieved by changing the spacing of the folds 20 and 22 held together.
