Description
Vorliegende Erfindung betrifft eine sanitäre Binde sowie ein Verfahren zu ihrer Herstellung. The present invention relates to a sanitary napkin and a method for its production.
Es sind bereits eine Reihe von Patenten bekannt, die sanitäre Binden und ähnliche saugfähige Polster betreffen. Man hat rege Aktivitäten entfaltet zur Entwicklung saugfähiger Innenlagen in diesen Hygieneartikeln. Die Innenlagen bekannter Hygieneartikel sind zwar ausreichend saugfähig, um eine beträchtliche Menge austretender Flüssigkeit aufzunehmen; sie besitzen aber nicht die Fähigkeit, plötzlich in grosser Menge auftretende Flüssigkeiten unterzubringen und dadurch ein Durchsickern zu verhindern, weil der Innenteil solcher bekannter Hygieneartikel nicht für die rasche Aufnahme grösserer Flüssigkeitsmengen eingerichtet ist. Anderseits sind sanitäre Binden wie Monatsbinden bekannt, deren Innenteil zwar in der Lage ist, das Durchsickern von A number of patents are already known relating to sanitary napkins and similar absorbent pads. Lively activities have been developed to develop absorbent inner layers in these hygiene articles. The inner layers of known hygiene articles are sufficiently absorbent to absorb a considerable amount of escaping liquid; however, they do not have the ability to accommodate suddenly occurring liquids in large quantities and thereby prevent leakage, because the inner part of such known hygiene articles is not designed for the rapid absorption of large quantities of liquids. On the other hand, sanitary napkins such as sanitary napkins are known, the inner part of which is capable of seeping through
Flüssigkeitsergüssen zu verhindern, die jedoch nicht innerhalb angemessener Zeit ëine genügende Gesamtmenge an Flüssigkeit zu absorbieren vermögen, weil durch die Mittel zur raschen Flüssigkeitsaufnahme die Gesamtkapazität der Innenlagen zur Aufnahme von Flüssigkeit reduziert wird. To prevent liquid effusions, which, however, are not able to absorb a sufficient total amount of liquid within a reasonable time, because the means for rapid liquid absorption reduce the overall capacity of the inner layers for absorbing liquid.
Es sind bereits verschiedenej Mittel zur Adsorption, zur Übertragung und zur Verteilung von Flüssigkeit in einem Innenteil verwendet worden, beispielsweise gemäss US-PS 2 896 627 in Längsrichtung gewelltes Papier in der Mitte des Innenteiles. Es sind auch schon Aussparungen und Bohrungen in den Innenteilen vorgesehen worden, wie beispielsweise in den US-PS 3 593 717, 3 403 689, 3 046 986 und 3 749 627 beschrieben worden ist. Zur Erhöhung der Absorptionsmengen hat man auch schon Präge- und Faltverfahren benutzt, wie beispielsweise aus US-PS 2 952 260 hervorgeht. Gemäss US-PS 3 291 131 können Monatsbinden auf flexiblen Fliessbändern hergestellt werden. Andere das Verfahren zur Herstellung saugfähiger Polster auf flexiblen Transporteinrichtungen betreffende US-Patentschriften sind 2 973 760, '3 268 954,2 872 023, 3 225 898, 3 439 795 und 3 203 419. Various means of adsorbing, transferring, and distributing liquid in an inner portion have been used, such as longitudinally corrugated paper in the center of the inner portion in accordance with U.S. Patent No. 2,896,627. Recesses and bores have also already been provided in the inner parts, as has been described, for example, in US Pat. Nos. 3,593,717, 3,403,689, 3,046,986 and 3,749,627. Embossing and folding processes have also been used to increase the absorption amounts, as can be seen, for example, from US Pat. No. 2,952,260. According to US Pat. No. 3,291,131, sanitary napkins can be produced on flexible conveyor belts. Other U.S. patents relating to the method of making absorbent pads on flexible conveyors are 2,973,760, 3,268,954.2,872,023, 3,225,898, 3,439,795 and 3,203,419.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, sanitäre Binden zu schaffen, die die vorstehend aufgezeigten Mängel der bekannten Hygieneartikel ganz oder weitgehend vermeiden, sowie ein Verfahren zur Herstellung von sanitären Binden bereitzustellen, das in einfacher Weise die erfin-dungsgemässen Binden herzustellen ermöglicht, ohne dass es durch das Herstellungsverfahren zu einer Beeinträchtigung der Gesamtabsorptionsfähigkeit und der raschen Aufnahmefähigkeit des Endproduktes für grössere Flüssigkeitsmengen kommt. The present invention has for its object to provide sanitary napkins that completely or largely avoid the above-mentioned shortcomings of the known hygiene articles, and to provide a method for the production of sanitary napkins that makes it possible to produce the sanitary napkins according to the invention in a simple manner without the manufacturing process adversely affects the overall absorption capacity and the rapid absorption capacity of the end product for larger amounts of liquid.
Erfindungsgemäss wird die Aufgabe gelöst durch eine sanitäre Binde, bestehend aus einer saugfähigen Kernlage mit einer gewellten Gewebeschicht, die zwischen zwei Schichten aus weicher, lockerer Fasermasse Hegt, unteren und oberen Schichten aus Watte, die unter und über der saugfähigen Kernlage angeordnet sind, einer flüssigkeitsundurchlässigen Folie, die um die obere Watteschicht und die saugfähige Kernlage gewickelt ist und deren Enden an der unteren Watteschicht befestigt sind, und einem blattförmigen Vliesstoff, der die Watteschichten, die Kernlage und die flüssigkeitsundurchlässige Folie einhüllt. According to the invention, the object is achieved by a sanitary napkin, consisting of an absorbent core layer with a corrugated fabric layer which lies between two layers of soft, loose fiber mass, lower and upper layers of cotton wool, which are arranged below and above the absorbent core layer, a liquid-impermeable layer Foil wrapped around the top layer of cotton and the absorbent core layer and the ends of which are attached to the bottom layer of cotton and a sheet-like nonwoven material which envelops the layers of cotton, the core layer and the liquid-impermeable film.
Die erfindungsgemässen sanitären Binden können auftretenden Flüssigkeitsergüssen widerstehen und eine ausserordentlich hohe Gesamtabsorptionsfähigkeit besitzen. The sanitary napkins according to the invention can withstand occurring liquid effusions and have an extraordinarily high total absorption capacity.
Die Erfindung erstreckt sich ferner auf ein Verfahren zur Herstellung der sanitären Binden, das dadurch gekennzeichnet ist, dass man eine erste Schicht aus weicher, lockerer Fasermasse, die an ihrer Unterseite unterteilte Aussparungen aufweist, auf eine untere Watteschicht aufbringt, eine gewellte Blattfläche auf die obere Seite der ersten Schicht und auf die gewellte Blattfläche eine zweite Schicht aus weicher, lok-kerer Fasermasse aufbringt, wobei eine saugfähige Kernlage entsteht, auf die eine obere Watteschicht gelegt wird, anschliessend obere und untere Watteschicht mittels einer Walze zusammenfältelt («roller crimped together»), das so aufgebaute Material durch Schneiden und Ausstanzen formt, es danach um 90° dreht, dann eine flüssigkeitsundurchlässige Folie um die obere Watteschicht und die saugfähige Kern-lage wickelt und ihre unterteilten Ränder an der unteren Watteschicht befestigt und schliesslich das so erhaltene Gefüge mit blattförmigem Vliesstoff umhüllt. The invention further extends to a method for producing the sanitary napkins, which is characterized in that a first layer of soft, loose fiber mass, which has subdivided recesses on its underside, is applied to a lower layer of cotton wool, a corrugated sheet surface on the upper Apply a second layer of soft, looser fiber mass on the side of the first layer and on the corrugated sheet surface, creating an absorbent core layer on which an upper cotton layer is placed, then folding the upper and lower cotton layers together using a roller (“roller crimped together”) ), forms the material thus constructed by cutting and punching it out, then turns it through 90 °, then wraps a liquid-impermeable film around the upper wadding layer and the absorbent core layer and fastens its divided edges to the lower wadding layer and finally the structure thus obtained sheet-like nonwoven wrapped.

die Schichten aus weicher, lockerer Fasermasse gelegt. Eine Folie aus Polyethylen oder einem ähnlichen flüssigkeitsundurchlässigen Material wird um die obere weiche, lockere Fasermassenschicht gewickelt, und die obere Watteschicht dehnt sich so aus, dass ihre Kanten überstehen und fest an den Kantenteilen der unteren Watteschicht haften. Die Enden der Watteschichten werden gefältelt und ein blattförmiger Vliesstoff um das ganze Gefüge gewickelt und mit Hilfe eines druckempfindlichen Klebemittels befestigt. the layers are laid out of soft, loose fiber mass. A film of polyethylene or a similar liquid-impermeable material is wrapped around the upper soft, loose fiber mass layer, and the upper cotton layer expands so that its edges protrude and adhere firmly to the edge parts of the lower cotton layer. The ends of the cotton layers are pleated and a sheet-like nonwoven is wrapped around the entire structure and attached using a pressure-sensitive adhesive.
Letzteres dient auch als Haftmittel während des Gebrauchs der Binde. Ein Trennpapier, beispielsweise ein mit Silikon behandeltes Papier, wird auf dem Klebemittel angebracht, um das Produkt zu schützen, bis es gebraucht wird. The latter also serves as an adhesive during use of the bandage. A release paper, such as silicone-treated paper, is placed on the adhesive to protect the product until it is needed.

Als Beispiel für eine erfindungsgemässe sanitäre Binde ist in Fig. 2 eine Monatsbinde 10 in Draufsicht dargestellt, die eine saugfähige Kernlage 12 enthält. Die saugfähige Kernlage 12 besteht aus einer oberen Schicht 14 aus einer weichen, lockeren Fasermasse und einer unteren Schicht 16 ebenfalls aus einer weichen, lockeren Fasermasse, wobei in letzterer Aussparungen 18 vorgesehen sind, die sich fast ganz, aber nicht vollständig durch die Schicht 16 erstrecken. Die Aussparungen 18 sind so angeordnet, dass sie dem Benutzer zugewandt sind. As an example of a sanitary napkin according to the invention, a sanitary napkin 10 is shown in plan view in FIG. 2, which contains an absorbent core layer 12. The absorbent core layer 12 consists of an upper layer 14 made of a soft, loose fiber mass and a lower layer 16 also made of a soft, loose fiber mass, recesses 18 being provided in the latter, which extend almost completely, but not completely, through the layer 16 . The recesses 18 are arranged so that they face the user.
Eine zweischichtige, gewellte Gewebefläche 20 liegt zwischen den Schichten 14 und 16 aus weicher, lockerer Fasermasse. Unter der Schicht 16 befindet sich eine zweischichtige Watteeinlage 22, während eine obere zweischichtige Watteeinlage 24 die obere Fläche der Schicht 14 überdeckt. Eine Folie aus wasserundurchlässigem Material 26, z.B. aus Polyethylen, liegt auf der Watteschicht 24, breitet sich über die Kernlage 12 aus und ist an den Rändern der unteren Watteschicht 22 mit Hilfe von Klebstoff oder Leim 28, der an den Endstücken 30 und 32 vorgesehen ist, befestigt. Die Endstücke 30 und 32 erstrecken sich nicht bis unter die Aus- A two-layer, corrugated fabric surface 20 lies between the layers 14 and 16 of soft, loose fiber mass. Under the layer 16 there is a two-layer cotton insert 22, while an upper two-layer cotton insert 24 covers the upper surface of the layer 14. A film of waterproof material 26, e.g. made of polyethylene, lies on the cotton layer 24, spreads over the core layer 12 and is attached to the edges of the lower cotton layer 22 with the aid of adhesive or glue 28, which is provided on the end pieces 30 and 32. The end pieces 30 and 32 do not extend below the

sparungen 18. Ein blattförmiges Faservlies 34, das die untere Watteschicht 22 überdeckt, umhüllt die obere Watteschicht 24 und die wasserundurchlässige Folie 26 so, dass sie sie überdeckt, wobei sie an ihren Rändern durch druckempfindliche Klebemittel 36 befestigt werden kann. Ein Streifen aus silikonhaltigem Trennpapier 38 ist mit druckempfindlichem Klebemittel 40 versehen und wird so befestigt, dass er über dem Vliesstoff 34 liegt. Die Enden der Watteschichten 24 und 22 und die Enden des blattförmigen Vliesstoffes 34 werden mit einer Walze zusammengefältelt zu Endstücken 42. Die Aussparungen 18 sind für die Aufnahme von Flüssigkeitsergüssen vorgesehen, während die gewellte Gewebefläche 20, die vorzugsweise in Längsrichtung gewellt ist, für die Flüssigkeitsverteilung von der saugfähigen Fasermassenschicht 16 zur saugfähigen Fasermassenschicht 14 vorgesehen ist. Das blattförmige Faservlies 34 sorgt für eine trok-kene Kontaktfläche, während die wasserundurchlässige Folie 26 vor Undichtigkeit schützen soll. Savings 18. A sheet-like non-woven fabric 34 covering the lower cotton layer 22 envelops the upper cotton layer 24 and the water-impermeable film 26 so that it covers them, whereby they can be attached to their edges by pressure-sensitive adhesive 36. A strip of silicone-containing release paper 38 is provided with pressure-sensitive adhesive 40 and is attached so that it lies over the nonwoven fabric 34. The ends of the cotton layers 24 and 22 and the ends of the sheet-like nonwoven fabric 34 are folded together with a roller to form end pieces 42. The cutouts 18 are provided for the reception of liquid effusions, while the corrugated fabric surface 20, which is preferably corrugated in the longitudinal direction, for the liquid distribution from the absorbent fiber mass layer 16 to the absorbent fiber mass layer 14 is provided. The sheet-shaped non-woven fabric 34 ensures a dry contact surface, while the water-impermeable film 26 is intended to protect against leaks.
Die sanitären Binden werden auf einem endlosen Förderband hergestellt, wobei man zwei voneinander getrennte Lagen aus weicher, lockerer Fasermasse einsetzt, die übereinan-derliegen mit einer dazwischen liegenden zweischichtigen, gewellten Gewebefläche 20. Die Bodenschicht der lockeren Fasermasse enthält die Aussparungen 18. Die saugfähige Kernlage 12 liegt auf der unteren Watteschicht 22, die zweischichtig ist und die in Längsrichtung rund um die saugfähige Kernlage gefaltet ist, wogegen die obere Watteschicht 24 auf der Kernlage 12 liegt und obere und untere Watteschichten durch Walzen zusammengefältelt sind. Anschlissend wird das streifenförmige Gefüge durch Schneiden und Ausstanzen geformt und dann um 90° gedreht, so dass man eine Polyethylenfolie 26 über den oberen Teil zuführen, ringsherum falten und längs der Leimfugen auf der unteren Watteschicht 22 befestigen kann. Danach wird die Binde mit dem blattförmigen Vliesstoff 34 umwickelt und seine Ränder durch Klebemittel befestigt, die auch dazu dienen, ein sili-konhaltiges Trennpapier als Versiegelung darauf festzuhalten, solange das Produkt nicht gebraucht wird. The sanitary napkins are produced on an endless conveyor belt, using two separate layers of soft, loose fiber mass, which lie one above the other with an intervening two-layer, corrugated fabric surface 20. The bottom layer of the loose fiber mass contains the recesses 18. The absorbent core layer 12 lies on the lower wadding layer 22, which is two-layered and which is folded in the longitudinal direction around the absorbent core layer, whereas the upper wadding layer 24 lies on the core layer 12 and the upper and lower wadding layers are folded together by rolling. The strip-shaped structure is then shaped by cutting and punching out and then rotated through 90 °, so that a polyethylene film 26 can be fed over the upper part, folded around and fastened along the glue joints on the lower cotton layer 22. The bandage is then wrapped with the sheet-like nonwoven fabric 34 and its edges are fastened by adhesives which also serve to hold a release paper containing silicon as a seal thereon as long as the product is not in use.
Es sind viele Abänderungen und Varianten der erfin-dungsgemässen sanitären Wegwerfartikel, insbesondere der Monatsbinden, und des Verfahrens zu ihrer Herstellung möglich, die innerhalb des hier offenbarten erfindungsge-mässen Bereiches liegen. Many modifications and variants of the disposable sanitary articles according to the invention, in particular of the sanitary napkins, and of the method for their production are possible which are within the scope of the invention disclosed here.
