Hygienische Adsorptionsvorlage, wie Damenbinde oder dergl. Hygienic adsorption template, such as a sanitary napkin or the like.
Die Erfindung betrifft eine hygienische Adsorptionsvorlage wie Damenbinde, Windel, Krankenunterlage oder Wundabdeckung nach dem Oberbegriff des Patentanspruches Io Unter dem Begriff Damenbinde werden auch die sogen. Formbinden, die dünnen Binden sowie die Slip-Einlagen verstanden. Unter den Begriff Windel fallen auch die sogen. Tropfler-Hilfen und Erwachsenenwindeln.The invention relates to a hygienic adsorption pad such as a sanitary napkin, diaper, mattress or wound cover according to the preamble of claim Io Under the term sanitary napkin are also the so-called. Form binding, understood the thin bandages as well as the panty liners. The term diaper also includes the so-called. Dropper aids and adult diapers.
Derartige Adsorptionsvorlagen werden in unterschiedlicher Größe und Stärke hergestellt und nach einmaligem Gebrauch weggeworfen- Die Vorlagen müssen infolgedessen möglichst billig sein, andererseits aber doch ihren Zweck möglichst vollkommen erfüllen. Im Rahmen dieser Aufgabe hat das Saugkissen die anfallende Körperflüssigkeit aufzusaugen und während des Gebrauches möglichst festzuhalten. Um einen zusätzlichen Schutz der Wäsche zu haben, ist das Saugkissen auf der vom Körper abgewandten Seite mit einer flüssigkeitsundurchlässigen Folie, der sogenannten Wäscheschutzfolie abgedeckt. Diese Folie besteht in aller Regel aus einer sehr dünnen Polyäthylenfolie, die bei der Herstellung der Adsorptionsvorlage maschinell in diese eingearbeitet wird. Um eine möglichst weitgehende Trennung des Saugkissens von der Wäsche zu erreichen, ist es bekannt, die Wäscheschutzfolie auch um die Längsseite des Saugkissens herumzuschlagen, so daß die Wäscheschutzfolie als ganzes gesehen eine Art Rinne bildet. Man spricht in diesem Zusammenhang auch vom "Dachrinneneffekt". -Such adsorption templates are produced in different sizes and strengths and after a single use thrown away- As a result, the templates must be as cheap as possible, but on the other hand their purpose as possible completely fulfill. As part of this task, the absorbent pad has to suck up the accumulating body fluid and to hold on tight as possible during use. In order to have an additional protection of the laundry, the absorbent pad is on the side facing away from the body covered with a liquid-impermeable film, the so-called laundry protection film. This film usually consists of a very thin polyethylene film that is mechanically incorporated into the adsorption template during production will. In order to achieve the greatest possible separation of the absorbent pad from the laundry, it is known that Wrap laundry protection film around the long side of the absorbent pad so that the laundry protection film as a whole seen forms a kind of gutter. One speaks in this context of the "gutter effect". -
Das Einbringen der Wäscheschutzfolie und das exakte Umschlagen derselben um die Längsseiten des Saugkissens bereitet in der Praxis Schwierigkeiten, die verschiedene Ursachen haben. Die Hauptursache besteht darin, daß dieThe introduction of the laundry protection film and the exact folding over of the same around the long sides of the absorbent pad prepares them in practice difficulties which have various causes. The main cause is that the

Breite der sehr dünnen Wäscheschutzfolie möglichst sparsam bemessen wird, um die Kosten niedrig zu halten. Es gelingt oft nicht, ein derartig dünnes, nur eben ausreichend bemessenes Folienstück bei schnell laufender Maschine exakt in die Binde einzulegen und in der gewünschten Weise um die Längsseiten herumzuschlagen. Aus weiter zurückliegenden Veröffentlichungen ist es zwar bekannt, zur Herstellung derartiger Wäscheschutzeinlagen auch flüssigkeitsundurchlässig imprägnierte Papiere, beispielsweise wachsgetränkte Papiere u. ä. zu verwenden, die dann infolge ihrer größeren Steifigkeit etwas besser zu verarbeiten sind, jedoch stammen diese Vorschläge aus der Zeit, als auch dünne Polyäthylenfolien noch nicht zur Verfügung standen. Sie können heute infolge ihrer höheren Steifigkeit und der damit verbundenen Härte nicht mehr eingesetzt werden, wenn die Wünsche des Verbrauchers hinsichtlich Weichheit der Vorlagen erfüllt werden sollen.Width of the very thin laundry protection film as economical as possible is measured in order to keep costs down. Often it does not succeed, such a thin one, just sufficient to insert the measured piece of film exactly into the bandage while the machine is running at high speed and in the desired position Way to fold around the long sides. It is from earlier publications known, for the production of such protective laundry inserts also liquid-impermeable impregnated papers, for example To use wax-soaked papers and the like, which are then somewhat better due to their greater rigidity are to be processed, but these suggestions come from the time when thin polyethylene films were not yet used Were available. Today, due to their greater rigidity and the associated hardness, they can no longer are used when the wishes of the consumer with regard to the softness of the originals are to be met.
Der Erfindung liegt die Aufgabe zugrunde, eine hygienische Adsorptionsvorlage vorzuschlagen, die ohne Mehraufwand an Material einfacher herzustellen ist und bei der die Wäscheschutzeinlage exakter die Längsseiten des Saugkissens umgreift. Die Lösung dieser Aufgabe ergibt sich aus dem kennzeichnenden Teil des Patentanspruches 1.The invention is based on the object of proposing a hygienic adsorption template that can be used without additional effort is easier to manufacture in terms of material and in which the protective liner more precisely matches the long sides of the The suction pad. The solution to this problem results from the characterizing part of claim 1.
In Patentanspruch 2 ist eine bevorzugte Ausführungsform des erfindungsgemäß vorgeschlagenen Folienstückes, welches der Herstellung der hygienischen Adsorptionsvorlage dient, beschrieben. Die Patentansprüche 3,4 und 5 beschreiben Einzelheiten über den stofflichen Aufbau derartiger Folienstücke.In claim 2 is a preferred embodiment of the film piece proposed according to the invention, which is used for the production of the hygienic adsorption template serves, described. The patent claims 3, 4 and 5 describe details about the material structure of such Foil pieces.

Zwei Ausführungsbeispiele derartiger kombinierter Folienstücke sind in den Fig. 2 und 3 wiedergegeben. Bei der Ausführungsform gemäß Fig. 2 weist das Folienstück 7 ein flüssigkeitsdurchlässiges Mittelfeld 81 und zwei daran angrenzende flüssigkeitsundurchlässige Seitenfelder 9' auf. Bei der Ausführungsform gemäß Fig. 3 besteht das Folienstück 7 aus dem flüssigkeitsdurchlässigen Feld 8 sowie dem flüssigkeitsundurchlässigen Feld 9.Two exemplary embodiments of such combined pieces of film are shown in FIGS. In the embodiment according to FIG. 2, the piece of film 7 has a liquid-permeable central field 8 1 and two adjacent liquid-impermeable side fields 9 '. In the embodiment according to FIG. 3, the film piece 7 consists of the liquid-permeable field 8 and the liquid-impermeable field 9.
Bei der Herstellung der Adsorptionsvorlage wird das Folienstück 7 so um das Saugkissen 1 herumgelegt, daß die eine Seite des Saugkissens, die beim Gebrauch dem Körper zugewandt sein soll, lediglich von der flüssigkeitsdurchlässigen Deckfolie, also einem der Felder 8 oder 81 bedeckt ist. Die übrigen Felder der Folie werden alsdann um die Längsseiten und die Unterseite des Saugkissens herumgelegt. Bei einer Ausführungsform des kombinierten Folienstückes wie es in Fig. 2 dargestellt ist, treffen sich dann die beiden flüssigkeitsundurchlässigen Randstreifen 9' an der Unterseite und sie werden dort in an sich bekannter Weise mittels des dargestellten Schmelzkleberfadens verbunden oder sie werden einfach durch Wärme- und Druckbehandlung miteinander verschweißt, was ohne weiteres möglich ist, da in diesem Falle zwei Folienstücke mit thermoplastischen Eigenschaften aufeinander treffen.During the production of the adsorption sheet, the piece of film 7 is placed around the absorbent pad 1 in such a way that the one side of the absorbent pad which is to face the body during use is only covered by the liquid-permeable cover sheet, i.e. one of the fields 8 or 8 1 . The remaining fields of the film are then placed around the long sides and the underside of the absorbent pad. In one embodiment of the combined piece of film as shown in Fig. 2, the two liquid-impermeable edge strips 9 'then meet on the underside and they are connected there in a manner known per se by means of the hot melt adhesive thread shown or they are simply treated with heat and pressure welded together, which is easily possible, since in this case two pieces of film with thermoplastic properties meet.

durchlässigen Felder Folienstreifen, beispielsweise solche aus Polyäthylen, aufweisen, die dort aufgebracht sind. Zum Aufbringen ist es möglich, die Streifen dort durch Wärmebehandlung ganzflächig oder auch punkt- oder streifenweise festzubügeln oder sie durch Extrusion aufzubringen, durch Klebstoffe zu befestigen oder in ähnlicher Weise festzulegen. Desweiteren ist es möglich, die an sich porösen Vliesstoffstreifen an denjenigen Stellen, die flüssigkeitsundurchlässig werden sollen, mit geeigneten Stoffen, z. B. Silikonharzen zu tränken und dadurch abzudichten. Vorteilhaft ist es auch, das Folienstück aus thermoplastischem Vliesstoff herzustellen, beispielsweise aus einem sogen. "Spinnvliesstoff" und die flüssigkeitsundurchlässigen Felder 9 bzw. 9' durch Warmpressen oder Warmwalzen zu verdichten. Welche Ausführungsformen derartiger Folienstücke auch gewählt werden, in jedem Fall ergibt sich der Produktvorteil eines exakteren Sitzes der Wäscheschutzfolie sowie schließlich in manchen Fällen auch noch der Herstellungsvorteil, daß auf besondere während des Produktionsganges einzuarbeitende Streifen aus hauchdünner Polyäthylenfolie verzichtet werden kann und daß gegebenenfalls sogar noch der Schmelzkleberfaden 6 eingespart werden kann.permeable fields of film strips, for example those made of polyethylene, which are applied there. For application, it is possible to heat-treat the strips over the entire surface, or point or strip-wise iron them in place or apply them by extrusion, fix them with adhesives or in the like to be determined. Furthermore, it is possible to apply the nonwoven fabric strips, which are porous per se, to those places which to be impermeable to liquids, with suitable substances such. B. to soak silicone resins and thereby seal. It is also advantageous to produce the piece of film from thermoplastic nonwoven, for example from a so-called "Spunbonded fabric" and the liquid-impermeable panels 9 and 9 ', respectively, by hot pressing or hot rolling to compact. Whichever embodiments of such pieces of film are also chosen, in each case This results in the product advantage of a more precise fit of the laundry protection film and, finally, in some cases as well nor the manufacturing advantage that special strips of wafer-thin to be worked in during the production process Polyethylene film can be dispensed with and that possibly even the hot melt adhesive thread 6 can be saved can.
