Description

Die vorliegende Erfindung betrifft einen Staubsaugerbeutel mit einem luftdurchlässigen Beutel, an dem eine Einlassöffnung zum Einfügen eines Stutzens eines Staubsaugers vorgesehen ist, wobei die Einlassöffnung durch eine umlaufende Dichtung gebildet ist, und ein Verfahren zur Herstellung eines Staubsaugerbeutels.The present invention relates to a vacuum cleaner bag having an air-permeable bag on which an inlet opening for inserting a nozzle of a vacuum cleaner is provided, wherein the inlet opening is formed by a circumferential seal, and a method for producing a vacuum cleaner bag.

Es gibt Staubsaugerbeutel, bei denen um eine Einlassöffnung eine Dichtung aus Gummi angeordnet ist, die mit dem meist aus Filterpapier bestehenden Beutel verklebt ist. Die Dichtung aus Gummi bildet einen ebenen Ring aus, in den ein Stutzen eines Staubsaugers einfügbar ist. Einerseits ist die Herstellung einer solchen Dichtung aufwendig und andererseits ist die Qualität der Abdichtung begrenzt, da es zu Undichtigkeiten zwischen der elastischen Dichtung und dem Stutzen kommen kann, sodass Luft ungefiltert wieder an die Umgebung abgegeben wird.There are vacuum cleaner bags, which are arranged around an inlet opening, a seal made of rubber, which is glued to the existing mostly filter paper bag. The rubber seal forms a flat ring into which a nozzle of a vacuum cleaner can be inserted. On the one hand, the production of such a seal is complicated and on the other hand, the quality of the seal is limited, since it can cause leaks between the elastic seal and the nozzle, so that air is discharged unfiltered back to the environment.

Die DE 86 22 890 offenbart einen Filterbeutel für einen Staubsauger, bei dem eine Halteplatte aus thermoplastischen Kunststoff hergestellt ist. Mit der Halteplatte ist einstückig eine umlaufende Dichtlippe ausgebildet, die über den Umfang verteilt mehrere radiale Ausbuchtungen aufweist.The DE 86 22 890 discloses a filter bag for a vacuum cleaner in which a holding plate made of thermoplastic material is made. With the holding plate is integrally formed a circumferential sealing lip which has distributed over the circumference a plurality of radial bulges.

Zudem ist aus der DE 102 03 460 ein Staubsaugerbeutel bekannt, bei dem ein Vliesstoffmaterial eingesetzt wird und die Dichtung um die Einlassöffnung aus dem Vliesstoff selbst gebildet ist. Auch hier ist die Dichtung ringförmig um die Einlassöffnung angeordnet und eben. Wie in Figur 1 dargestellt ist, kann an einem solchen Staubsaugerbeutel 2 eine ringförmige Dichtung 3 angeordnet sein, die eine Einlassöffnung umgibt und in die ein Stutzen 1 einfügbar ist. Problematisch ist hierbei, dass um den Beutel 2 ein Unterdruck erzeugt wird und somit die elastische Dichtung 3 sich verformen kann und ein Spalt 5 zwischen Stutzen 1 und Dichtung 3 ausgebildet wird, durch den Luft entweichen kann, wie dies durch den Pfeil 4 dargestellt ist.Moreover, from the DE 102 03 460 a vacuum cleaner bag is known in which a nonwoven material is used and the seal is formed around the inlet opening of the nonwoven fabric itself. Again, the seal is arranged annularly around the inlet opening and flat. As in FIG. 1 is shown, may be arranged on such a vacuum cleaner bag 2, an annular seal 3, which surrounds an inlet opening and into which a nozzle 1 is inserted. The problem here is that around the bag 2, a negative pressure is generated and thus the elastic seal 3 can deform and a gap 5 between the nozzle 1 and seal 3 is formed, can escape through the air, as shown by the arrow 4.

Die EP 1 059 056 offenbart ein Verfahren zum Herstellen eines Staubsaugerbeutels, bei dem zwei übereinander liegende Bahnen zusammen mit einem Montageelement zur Herstellung einer Einlassöffnung gestanzt werden. Anschließend werden die Bahnen zu Staubsaugerbeuteln weiter verarbeitet.The EP 1 059 056 discloses a method for manufacturing a vacuum cleaner bag in which two superimposed webs are punched together with a mounting member for making an inlet opening. Subsequently, the webs are further processed to vacuum cleaner bags.

Es ist daher Aufgabe der vorliegenden Erfindung einen Staubsaugerbeutel und ein Verfahren zur Herstellung eines solchen Staubsaugerbeutels zu schaffen, bei dem eine hohe Qualität der Abdichtung an dem Stutzen gewährleistet wird.It is therefore an object of the present invention to provide a vacuum cleaner bag and a method for producing such a vacuum cleaner bag, in which a high quality of the seal is ensured at the nozzle.

Diese Aufgabe wird mit einem Staubsaugerbeutel mit den Merkmalen des Anspruches 1 und einem Verfahren zur Herstellung eines Staubsaugerbeutels mit den Merkmalen des Anspruches 6 gelöst.This object is achieved with a vacuum cleaner bag with the features of claim 1 and a method for producing a vacuum cleaner bag having the features of claim 6.

Ein erfindungsgemäßer Staubsaugerbeutel umfasst eine umlaufende Dichtung um eine Einlassöffnung, wobei die Dichtung in den Beutel hervorsteht und eine an den Stutzen anlegbare Dichtlippe ausbildet. Die Dichtung erstreckt sich somit teilweise in den Beutel hinein und bildet einen Schlauchabschnitt aus, der sich an den Einlassstutzen anlegen kann. Dadurch wird die Qualität der Abdichtung verbessert und zudem kann die Dichtung nicht mehr durch einen Unterdruck umgebogen werden, wie dies beim Stand der Technik der Fall ist. Denn die hervorstehende Dichtung wird durch den Stutzen gehalten und kann nicht durch den Unterdruck verformt werden. Die Dichtung ist dabei durch Prägen des Materials des Beutels um die Einlassöffnung hergestellt.A vacuum cleaner bag according to the invention comprises a circumferential seal around an inlet opening, wherein the seal protrudes into the bag and forms a sealing lip which can be applied to the neck. The seal thus partially extends into the bag and forms a section of tubing which is engageable with the inlet port. As a result, the quality of the seal is improved and also the seal can not be bent by a negative pressure, as is the case in the prior art. Because the protruding seal is held by the nozzle and can not be deformed by the negative pressure. The seal is made by embossing the material of the bag around the inlet opening.

Gemäß einer bevorzugten Ausgestaltung der Erfindung bildet die Dichtung einen in den Beutel hervorstehenden Ring aus. Dabei kann der Ring eine gewisse Elastizität aufweisen, damit der Stutzen formschlüssig in der Dichtung aufgenommen ist.According to a preferred embodiment of the invention, the seal forms a projecting into the bag ring. In this case, the ring may have a certain elasticity, so that the nozzle is positively received in the seal.

Um das Einfügen des Stutzens zu erleichtern, ist die Dichtung vorzugsweise zum Ende hin konisch verjüngt, wobei hier auch ein Toleranzausgleich stattfinden kann, falls Stutzen mit unterschiedlichem Durchmesser eingefügt werden.In order to facilitate the insertion of the nozzle, the seal is preferably tapered towards the end, in which case a tolerance compensation can take place if nozzles with different diameters are inserted.

Der Beutel kann beispielsweise aus Vliesstoff gebildet sein, der um die Einlassöffnung geprägt wird. Ferner kann eine Halteplatte und eine Verschlussplatte aus Kunststoff um die Einlassöffnung vorgesehen sein, um die Einlassöffnung beim Entsorgen des Beutels verschließen zu können.The bag may for example be formed of nonwoven fabric which is embossed around the inlet opening. Furthermore, a holding plate and a closure plate can be made Plastic may be provided around the inlet opening to close the inlet opening upon disposal of the bag can.

Gemäß dem erfindungsgemäßen Verfahren wird eine Materialbahn nach dem Stanzen einer Einlassöffnung um die Einlassöffnung herum geprägt, wobei eine ringförmig hervorstehende Dichtlippe hergestellt wird. Anschließend wird die Materialbahn noch mit einer weiteren Materialbahn zusammengefügt, zugeschnitten und fertiggestellt, wobei eine Halteplatte um die Einlassöffnung festgelegt wird.According to the method of the invention, a material web is embossed after the punching of an inlet opening around the inlet opening, whereby an annularly protruding sealing lip is produced. Subsequently, the material web is still joined together with a further material web, cut to size and finished, wherein a holding plate is fixed around the inlet opening.

Gemäß einer Weiterbildung des Verfahrens wird beim Prägen das Material durch den Prägestempel und die Prägematritze erwärmt, vorzugsweise auf eine Temperatur zwischen 50 und 200°C. Durch das Erwärmen des Materials kann das Vliesstoffmaterial unter Beibehaltung einer gewissen Elastizität verformt werden.According to a development of the method, the material is embossed by the embossing punch and the embossing die, preferably to a temperature between 50 and 200 ° C. By heating the material, the nonwoven material can be deformed while maintaining a certain elasticity.
