Abstract
Description
Wäschesack Laundry bag
Die Erfindung betrifft einen Wäschesack aus einer Polyvinylalkoholfolie mit mindestens einer, den Wäschesack entlang einer Seite schließenden Naht, insbesondere einer Schweißnaht.The invention relates to a laundry bag made from a polyvinyl alcohol film with at least one seam closing the laundry bag along one side, in particular a weld.
Derartige wasserlösliche Wäschesäcke sind bekannt und werden insbesondere in Krankenhäusern eingesetzt.Such water-soluble laundry bags are known and are in particular used in hospitals.
Schmutzwäsche wird in diese Wäschesäcke eingefüllt, und danach wird dieser luftdicht verschlossen und zur Wäscherei oder Wäscheabteilung transportiert. In der Wäscherei wird der Wäschesack nicht geöffnet sondern mit Inhalt in die Waschmaschine geworfen, in der während des ersten Kaltspülganges die Nähte sich lösen und die Wäsche aus dem Wäschesack heraustritt. Die warmwasserlösliche Folie löst sich während späterer Waschvorgänge restlos auf und wird herausgespült.Dirty laundry is poured into these laundry bags, and afterwards this is hermetically sealed and transported to the laundry or laundry department. In the laundry, the laundry bag is not opened, but rather with the contents in the washing machine thrown, in which the seams loosen during the first cold rinse and the Laundry comes out of the laundry bag. The hot water soluble film dissolves during in later washing processes and is rinsed out.
Aufgrund dieser Wäschesäcke ist sichergestellt, daß nach dem Füllen weder das Wäschereipersonal noch den Transport der Wäschesäcke übernehmende- Personen mit infizierter oder stark verschmutzter Wäsche in Berührung kommen.Because of these laundry bags it is ensured that after filling neither the laundry staff nor the Transport of the laundry bags People come into contact with infected or heavily soiled laundry.
Bei diesen bekannten Wäschesäcken wird ein Lösen der Nähte während des ersten Kaltwaschvorgangs dadurch erreicht, daß im Bereich der Nähte zwischen den aus warmwasserlöslicher Folie bestehenden Wäschesackwandungen ein Band aus kaltwasserlöslicher Polyvinylalkoholfolie einliegt, die mit den Folien der Wandung verschweißt ist und nach dem Zutritt von Kaltwasser den Halt der Schweißnaht aufhebt. Das exakte Einlegen eines solchen Folienbandes im Bereich der Nähte ist aufwendig, erschwert die Produktion und führt zu hohen Ausschußraten bei großen Stückzahlen pro Zeiteinheit.In these known laundry bags a loosening of the seams is during the first cold wash achieved in that in the area of the seams between the laundry bag walls, which are made of hot water soluble film, have a band of cold water soluble ones Polyvinyl alcohol film is inserted, which is welded to the film of the wall and after the entry of cold water, the hold of the weld seam is released. The exact insertion Such a film tape in the area of the seams is expensive and makes production more difficult and leads to high reject rates with large numbers of items per unit of time.
Aufgabe der Erfindung ist es, einen Wäschesack der eingangs genannten Art derart zu verbessern, daß er einfach, schnell-und preiswert herstellbar ist und eine Massenproduktion bei geringem Ausschuß erlaubt.The object of the invention is to provide a laundry bag of the type mentioned at the beginning Kind to be improved in such a way that it can be produced simply, quickly and inexpensively and allows mass production with low scrap.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Wäschesackwandung aus zwei#Schichten besteht, von denen die innenliegende kaltwasserlöslich und die äußere warmwasserlöslich ist.This object is achieved according to the invention in that the laundry bag wall consists of two # layers, of which the inside is cold water soluble and the outer is soluble in warm water.
Bei einem solchen Wäschesack können die Wandungen aneinandergeschweißt werden, ohne eine zusätzliche kaltwasserlösliche Folie dazwischen legen zu müssen. Die Wäschesäcke können in hohen Stückzahlen sehr schnell hergestellt werden, und während der Herstellung braucht mit Ausschuß nicht-gerechnet zu werden. Vorzugsweise wird vorgeschlagen, daß alle Verbindungsnähte Schweißnähte sind.In the case of such a laundry bag, the walls can be welded to one another without having to put an additional cold water-soluble film in between. The laundry bags can be produced in large numbers very quickly, and There is no need to reckon with rejects during production. Preferably will suggested that all connecting seams are welds.
Eine besonders einfache und preiswerte Herstellung wird dadurch erreicht, daß beide Schichten der Wandung zusammen gleichzeitig durch Extrudieren (koextrudieren) herstellbar sind. Hierdurch liegen die beiden Schichten sofort von der Herstellung an unlösbar aneinander.A particularly simple and inexpensive production is achieved by that both layers of the wall together at the same time by extrusion (coextrusion) can be produced. As a result, the two layers are immediately from production inseparable from each other.
Eine besonders preiswerte und einfache Herstellung wird dadurch erzielt, daß die Wandung schlauchförmig und die Unterseite durch eine Schweißnaht verschlossen ist. Hierbei bietet sich besonders vorteilhaft das Folienblasverfahren an, da der Schlauch durch Extrudieren herstellbar ist.A particularly inexpensive and simple production is achieved by that the wall is tubular and the bottom is closed by a weld is. The blown film process is particularly advantageous here, since the Hose can be produced by extrusion.
Alternativ wird vorgeschlagen, daß die innere Schicht nur im Bereich der Nähte angeordnet ist und von einem kaltwasserlöslichen Kleber gebildet wird. Ein Öffnen der zugebundenen oberen Einfüllöffnung während des ersten Waschvorganges wi-d dadurch erreicht, daß in der Nähe der Einfüllöffnung ein Band aus kaltwasserlöslicher Polyvinylalkoholfolie anbringbar oder befestigt ist.Alternatively, it is suggested that the inner layer should only be used in the area the seams is arranged and is formed by a cold water soluble adhesive. Opening the tied upper filling opening during the first washing process wi-d achieved in that a band of cold water soluble in the vicinity of the filling opening Polyvinyl alcohol film is attachable or attached.
Zwei Ausführungsbeispiele der Erfindung sind in den Zeichnungen schematisch dargestellt und werden im folgenden näher beschrieben. Es zeigen: Fig. 1 eine Seitenansicht eines Wäschesackes in einer ersten Ausführungsart und Fig. 2 eine Seitenansicht eines Wäschesackes in einer zweiten Ausführungsart.Two embodiments of the invention are shown schematically in the drawings and are described in more detail below. 1 shows a side view a laundry bag in a first embodiment and Fig. 2 a Side view of a laundry bag in a second embodiment.
Die Wandung des Wäschesackes besteht aus einer zweischichtigen Folie aus Polyvinylalkohol, von der eine Schicht kaltwasserlöslich und die zweite warmwasserlöslich ist. Diese unlösbar aneinander anliegenden Schichten werden durch Extrudieren im Extruder, insbesondere durch das Folienblasverfahren, hergestellt, wobei die Ringdüse der Extruderanlage gleichzeitig beide Materialien, d.h. das kaltwasserlösliche Material und das warmwasserlösliche Material, zusammen ausstößt, so daß beide Folienschichten aneinander verschmolzen sind. Durch in das Innere der Ringdüse eingeblasene Luft wird der Folienschlauch auf ein Mehrfaches seines ursprünglichen Durchmessers aufgeblasen und danach zu den. Wäschesäcken durch Schweißen und Trennen konfektioniert.The wall of the laundry bag consists of a two-layer film made of polyvinyl alcohol, of which one layer is soluble in cold water and the second is soluble in warm water is. These inextricably abutting layers are extruded in the Extruder, in particular by the blown film process, produced, the ring nozzle the extruder system at the same time both materials, i.e. the cold-water-soluble material and the warm water soluble material, ejects together so that both film layers are fused together. By air blown inside the ring nozzle the film tube is inflated to a multiple of its original diameter and then to the. Laundry bags made up by welding and cutting.
In dem Fall, in dem der aus der Extruderanlage erhaltene Schlauch die Größe des gewünschten Wäschesackes la aufweist, brauchttder Schlauch 2 nur noch in den gewünschten Abständen der Wäschesacklänge mit einer querliegenden Schweißnaht 3 versehen zu werden. Dabei ist darauf zu achten, daß die kaltwasserlösliche Folienschicht innen und die warmwasserlösliche Schicht außen liegt.In the case where the hose obtained from the extruder plant is the size of the desired laundry bag la, the hose 2 only needs in the desired intervals of the laundry bag length with a transverse weld seam 3 to be provided. Care must be taken that the film layer is soluble in cold water inside and the warm water-soluble layer is outside.
Weist dagegen der von der Extruderanlage erstellte Schlauch einen größeren Durchmesser auf als der gewünschte Wäschesack, so wird der Folienschlauch längs aufgeschnitten und das Folienmaterial zu Wäschesäcken 1b verarbeitet, die eine untere quer liegende Schweißnaht 3 und an den Längsrändern Schweißnähte 4 und 5 aufweisen. Ein an der Außenwandung des Wäschesackes befestigtes Band 6 aus kaltwasserlöslicher Polyvinylalkoholfolie wird zum Zuschnüren der Einf-üllöffnung 7 des Wäschesackes verwendet.If, on the other hand, the hose created by the extruder system has a larger diameter than the desired laundry bag, so will the tubular film Cut open lengthways and the film material into laundry bags 1b processed, the one lower transverse weld 3 and on the longitudinal edges Have welds 4 and 5. One attached to the outer wall of the laundry bag Tape 6 made of cold-water-soluble polyvinyl alcohol film is used to close the filling opening 7 of the laundry bag is used.
Bei diesem Wäschesack löst sich während des Kaltwasserwaschvorgangs zuerst die innen liegende kaltwasserlösliche Folienschicht auf. Da diese innen liegenden Folienschichten im Bereich der Schweißnähte aneinandergeschweißt sind, lösen sich die Nähte,und der Inhalt des Wäschesackes kann austreten. Ferner öffnet sich durch das Auflösen des Bandes 6 die Einfüllöffnung 7.This laundry bag comes loose during the cold water washing process first apply the cold water-soluble film layer on the inside. Because these internal Foil layers are welded to one another in the area of the weld seams, loosen the seams and the contents of the laundry bag can leak out. It also opens through the dissolving of the tape 6 the filling opening 7.
