Furthermore, the pop spring must be made very precise, as regards the crowning and the material in order to obtain a desired spring characteristic, which has a sufficient Provides closing force and on the other hand allows a large opening angle in operation.

Die Aufgabe der vorliegenden Erfindung besteht darin, angesichts der aus dem Stand der Technik bekannten Beutel einen Staubsaugerfilterbeutel bereitzustellen, der eine einfache und zuverlässige Verschlussvorrichtung aufweist..The object of the present invention is to provide, in view of the prior art bags, a vacuum cleaner filter bag which has a simple and reliable closure device.

Diese Aufgabe wird gelöst durch einen Staubsaugertlterbeutel gemäß Anspruch 1.This object is achieved by a vacuum cleaner bag according to claim 1.

Erfindungsgemäß wird demnach ein Staubsaugerfilterbeutel mit einer Einlassöffnung, einer an der Beutelaußenseite im Bereich der Einlassöffnung angeordneten Halteplatte, die an einer Halteeinrichtung eines Staubsaugers zur Halterung des Staubsaugerfilterbeutels anbringbar ist, und einer im Bereich der Einlassöffnung angeordneten Verschtussvorrichtung, die derart ausgebildet ist, dass sie eine erste Stellung einnimmt, wenn der Staubsaugerfilterbeutel nicht in den Staubsauger eingesetzt ist, und in eine zweite Stellung bringbar ist, wenn der StaubsaugerFlterbeutel in den Staubsauger eingesetzt ist, wobei die Einlassöffnung bei der ersten Stellung der Verschlussvorrichtung verschlossen ist und bei der zweiten Stellung der Verschlussvorrichtung geöffnet ist, bereitgestellt.According to the invention, therefore, a vacuum cleaner filter bag is provided with an inlet opening, a holding plate arranged on the outside of the bag in the region of the inlet opening, which can be attached to a holding device of a vacuum cleaner for holding the vacuum cleaner filter bag, and a closure device arranged in the region of the inlet opening, which is designed such that it has a assumes the first position when the vacuum cleaner filter bag is not inserted into the vacuum cleaner and can be brought to a second position when the vacuum cleaner bag is inserted into the vacuum cleaner, wherein the inlet opening is closed at the first position of the closure device and opened at the second position of the closure device is provided.

Wenn die Halteeinrichtung fest in dem Staubsauger angebracht ist, kann die Verschlussvorrichtung so bereits beim Anbringen der Halteplatte an der Halteeinrichtung in die zweite Stellung gebracht und somit geöffnet werden. Beim Entfernen aus der Halteeinrichtung wird die Verschlussvorrichtung wieder in ihre erste Stellung zurückkehren.If the holding device is fixedly mounted in the vacuum cleaner, the closure device can thus already brought when attaching the holding plate to the holding device in the second position and thus be opened. Upon removal from the holding device, the closure device will return to its first position.

Wenn die Halteeinrichtung beweglich, beispielsweise mittels eines Gelenks, an dem Staubsauger angebracht ist, um ein Wechseln des Staubsaugerbeutels durch Herausklappen der Halteeinrichtung aus dem Staubsauger zu erleichtern, kann die Verschlussvorrichtung in die zweite Stellung gebracht werden, wenn die Halteeinrichtung in die Stellung gebracht wird, die sie während des Betriebs des Staubsaugers einnimmt. Wenn die Halteeinrichtung zum Entfernen des Staubsaugerbeutels aus dem Staubsauger geklappt wird, schließt sich die Verschlussvorrichtung selbsttätig.If the holding device is movably attached to the vacuum cleaner, for example by means of a joint, to facilitate changing the vacuum cleaner bag by folding out the holding device from the vacuum cleaner, the closure device can be brought into the second position when the holding device is brought into position, which it occupies during operation of the vacuum cleaner. If the holding device for removing the vacuum cleaner bag is folded out of the vacuum cleaner, the closure device closes automatically.

Alternativ kann die Verschlussvorrichtung auch durch ein staubsaugerseitig vorgesehenes Element in die zweite Stellung gebracht, also geöffnet werden, und durch dieses Element wieder in die erste Stellung gebracht, also geschlossen, werden. Diese Alternative hat den Vorteil, dass die Verschlussvorrichtung nur während des eigentlichen Saugvorgangs geöffnet werden muss. Dies führt zum einen dazu, dass kein Staub aus dem Beutel fallen kann, wenn der Staubsauger nicht in Betrieb ist. Andererseits wird auch die Verschlussvorrichtung, die in ihrer zweiten geöffneten Stellung immer unter mechanischer Spannung steht, weniger beansprucht.Alternatively, the closure device can also be brought by a vacuum cleaner side provided element in the second position, so be opened, and brought by this element back to the first position, so closed, are. This alternative has the advantage that the closure device only has to be opened during the actual suction process. This leads to the fact that no dust can fall out of the bag when the vacuum cleaner is not in operation. On the other hand, the closure device, which is always under mechanical tension in its second open position, less stressed.

Der Verschlussmechanismus ist einfach, da die Verschlussvorrichtung grundsätzlich, wenn der Staubsaugerfilterbeutel nicht in dem Staubsauger angeordnet ist, die Einlassöffnung verschließt. Die verschlossene Einlassöffnung - solange der Beutel nicht in den Staubsauger eingesetzt ist - ermöglicht weiterhin ein Bereitstellen von lose im Staubsaugerfilterbeutel vorhandenen Partikeln, beispielsweise von Geruchsadsorbentien. Für die gewünschte Funktion ist die Verschlussvorrichtung insbesondere geeignet zu dimensionieren und im Beutelinnern anzuordnen.The shutter mechanism is simple because, when the vacuum cleaner filter bag is not disposed in the vacuum cleaner, the shutter device basically closes the inlet port. The closed inlet opening - as long as the bag is not inserted into the vacuum cleaner - also allows providing loose particles present in the vacuum cleaner filter bag, for example odor adsorbents. For the desired function, the closure device is particularly suitable for dimensioning and to be arranged inside the bag.

Gemäß einer Alternative kann die Verschlussvorrichtung im Beutelinnern im Bereich der Einlassöffnung angeordnet sein. Durch die im Beutelinnern angeordneten Verschlussvorrichtung wird ein Verschlusselement an der Halteplatte vermieden. Weiterhin kann damit die Verschlussvorrichtung in besonders einfacher Weise mit der Beutelwand verbunden werden.According to an alternative, the closure device can be arranged inside the bag in the region of the inlet opening. By arranged in the bag closure device closure element is avoided on the holding plate. Furthermore, so that the closure device can be connected in a particularly simple manner with the bag wall.

Die Verschlussvorrichtung kann an der Beutelinnenseite oder der Beutelaußenseite befestigt sein und die Einlassöffnung wenigstens teilweise umgeben. Damit wird insbesondere eine stabile Anordnung der Verschlussvorrichtung erhalten.The closure device may be attached to the inside of the bag or the outside of the bag and at least partially surround the inlet opening. In particular, a stable arrangement of the closure device is thus obtained.

Gemäß einer anderen Alternative kann die Verschlussvorrichtung an der Halteplatte angeordnet sein. In dieser Alternative lässt sich bei der Herstellung zunächst die Kombination aus Halteplatte und Verschlussvorrichtung ausbilden, die dann mit der Beutelwand verbunden wird. Hierzu lassen sich bekannte Verfahren zum Befestigen von Halteplatten an Beuteln einsetzen.According to another alternative, the closure device may be arranged on the holding plate. In this alternative, the combination of holding plate and closure device can initially be formed during production, which is then connected to the bag wall. For this purpose, known methods for attaching retaining plates to bags can be used.

In dieser Alternative kann die Verschlussvorrichtung an der der Beutelaußenseite zugewandten Seite der Halteplatte befestigt sein und die Einlassöffnung wenigstens teilweise umgeben. Auch dies ergibt eine stabile Anordnung der Verschlussvorrichtung.In this alternative, the closure device may be attached to the side of the holding plate facing the outside of the bag and at least partially surround the inlet opening. This also results in a stable arrangement of the closure device.

Die Verschlussvorrichtung der beschriebenen Staubsaugerfilterbeutel kann ein Federelement umfassen, das auf einen Teil der Verschlussvorrichtung eine Rückstellkraft derart ausübt, dass die Verschlussvorrichtung die erste Stellung einnimmt, wenn die Halteplatte nicht an der Halteeinrichtung angebracht ist.The closure device of the vacuum cleaner filter bag described may comprise a spring element which exerts on a part of the closure device a restoring force such that the closure device assumes the first position when the holding plate is not attached to the holding device.

Ein solches Federelement ermöglicht in einfacher Weise ein sicheres Verschließen der Einlassöffnung insbesondere beim einem Entfernen der Staubsaugerfilterbeutels aus dem Staubsauger.Such a spring element allows in a simple manner a secure closing of the inlet opening in particular when removing the vacuum cleaner filter bag from the vacuum cleaner.

Die Verschlussvorrichtung kann insbesondere Falzlinien oder Filmschamiere aufweisen, so dass die Verschlussvorrichtung von der ersten oder zweiten Stellung in die zweite bzw. erste Stellung bringbar ist. Derartige Falzlinien erlauben in einfacher und zuverlässiger Weise, die Verschlussvorrichtung von der einen in die andere Stellung zu bringen.The closure device may in particular have fold lines or film hinge, so that the closure device can be brought from the first or second position into the second or first position. Such fold lines allow a simple and reliable way to bring the closure device from one to the other position.

Die Verschlussvorrichtung der zuvor beschriebenen Staubsaugerfilterbeutel kann derart ausgebildet sein, dass sie in der ersten Stellung eine im Vergleich zur zweiten Stellung verringerte Ausdehnung senkrecht zur Ebene der Einlassöffnung aufweist.The closure device of the vacuum cleaner filter bag described above may be formed such that in the first position it has a reduced extent compared to the second position perpendicular to the plane of the inlet opening.

Dies bedeutet, dass die Verschlussvorrichtung zusammenlegbar ist. Durch die kleinere Ausdehnung in der zweiten Stellung lässt sich der Staubsaugerfilterbeutel, insbesondere vor dem Gebrauch, in eine sehr kompakte Form bringen. Dies ist bei Flachbeuteln von besonderem Vorteil, die sich damit zum Verpacken auf bestimmte Formate zusammenfalten lassen. Durch derartige zusammenlegbare Verschlussvorrichtungen lässt sich vermeiden, dass die Dicke der zusammengelegten Beutel wesentlich erhöht wird. Vorzugsweise kann die Verschlussvorrichtung in der zweiten Stellung im wesentlichen flach ausgebildet sein.This means that the closure device is collapsible. Due to the smaller extent in the second position, the vacuum cleaner filter bag, in particular before use, bring in a very compact form. This is of particular advantage in flat bags, which can thus be folded for packaging to specific formats. By such collapsible closure devices can be avoided that the thickness of the folded bag is substantially increased. Preferably, the closure device may be formed substantially flat in the second position.

Die zuvor beschriebenen Staubsaugerfilterbeutel können weiterhin wenigstens ein Dichtungselement, insbesondere zum Abdichten der Einlassöffnung, umfassen. Mit einem derartigen Dichtungselement kann insbesondere die Einlassöffnung einerseits um einen eingeführten Stutzen herum abgedichtet werden. Andererseits kann ein Dichtungselement zum Abdichten der Einlassöffnung in der ersten Stellung der Verschlussvorrichtung ausgebildet sein.The vacuum cleaner filter bags described above may further comprise at least one sealing element, in particular for sealing the inlet opening. With In particular, the inlet opening of such a sealing element can be sealed around an inserted neck. On the other hand, a sealing element for sealing the inlet opening may be formed in the first position of the closure device.

Das wenigstens eine Dichtungselement kann zwischen der Einlassöffnung und der Verschlussvorrichtung und/oder innerhalb der Verschlussvorrichtung angeordnet sein. Durch eine geeignete Wahl der Anordnung des wenigstens einen Dichtungselements kann die Einlassöffnung in der ersten Stellung des Verschlusselements optimal verschlossen werden.The at least one sealing element may be arranged between the inlet opening and the closure device and / or inside the closure device. By a suitable choice of the arrangement of the at least one sealing element, the inlet opening in the first position of the closure element can be optimally closed.

Das Material des Dichtungselements kann Gummi, ein Elastomer, eine Folie oder einen Schaum, insbesondere einen geschlossenzelligen Schaum, umfassen.The material of the sealing element may comprise rubber, an elastomer, a foil or a foam, in particular a closed-cell foam.

Die Verschlussvorrichtung der zuvor beschriebenen Staubsaugerfilterbeutel kann ein im wesentlichen luftundurchlässiges Material umfassen.The closure device of the previously described vacuum cleaner filter bag may comprise a substantially air-impermeable material.

Das Material der Verschlussvorrichtung kann einen Kunststoff, ein trocken- oder nassgelegtes Vlies oder Papier, insbesondere Pappe, oder eine Folie umfassen. Auch andere Materialien sind möglich; insbesondere ist eine ausreichende Steifigkeit des Materials von Vorteil, damit die Verschlussvorrichtung durch den Luftstrom im Betrieb nicht übermäßig bewegt wird. Das Material der Verschlussvorrichtung kann insbesondere gleich dem Material der Halteplatte sein; beispielsweise können die Verschlussvorrichtung und die Halteplatte als ein einstückiges Spritzgussteil ausgebildet sein.The material of the closure device may comprise a plastic, a dry or wet-laid nonwoven or paper, in particular cardboard, or a film. Other materials are possible; In particular, a sufficient rigidity of the material is advantageous so that the closure device is not excessively moved by the air flow during operation. The material of the closure device may in particular be equal to the material of the holding plate; For example, the closure device and the holding plate may be formed as a one-piece injection-molded part.

Die Verschlussvorrichtung kann mit dem Filtermaterial der Staubsaugerfilterbeutelwand und/oder mit der Halteplatte verklebt oder verschweißt sein. Beispielsweise kann die Verschlussvorrichtung an Verbindungsstellen mit der Beutelinnenseite Polyethylen oder Polypropylen umfassen oder damit beschichtet sein. Dies ermöglicht, die Verschlussvorrichtung und eine diese Materialien umfassende Halteplatte mittels Ultraschallschweißen gleichzeitig am Filtermaterial der Beutelwand zu befestigen.The closure device can be glued or welded to the filter material of the vacuum cleaner filter bag wall and / or to the holding plate. For example, the closure device may comprise or be coated with polyethylene or polypropylene at joints with the inside of the bag. This makes it possible to attach the closure device and a holding plate comprising these materials by means of ultrasonic welding simultaneously on the filter material of the bag wall.

Erfindungsgemäß umfasst die Verschlussvorrichtung in der zweiten Stellung wenigstens eine der Einlassöffnung gegenüberliegende de Verschlussfläche. Eine solche Verschlussfläche verschließt dann bei einem "Zusammenlegen" der Verschlussvorrichtung, bei die erste Stellung eingenommen wird, die Einlassöffnung in geeigneter Weise.According to the invention, the closure device comprises in the second position at least one inlet opening opposite de closing surface. Such a closure surface then closes the inlet opening in a suitable manner in a "folding" of the closure device, in the first position is occupied.

In einer Weiterbildung kann die wenigstens eine Verschlussfläche in einem vorherbestimmten Winkel relativ zur Ebene der Einlassöffnung insbesondere parallel zur Ebene der Einlassöffnung, angeordnet sein.In a development, the at least one closure surface can be arranged at a predetermined angle relative to the plane of the inlet opening, in particular parallel to the plane of the inlet opening.

Durch eine geeignete Wahl des Winkels kann die Verschlussvorrichtung an unterschiedliche Parameter wie Beutelgeometrie bzw. -dimensionierung, Einströmwinkel eines Luftstroms im Betrieb angepasst und optimiert werden. Eine der Einlassöffnung gegenüberliegende Verschlussfläche kann insbesondere von dieser einen Abstand bzw. einen mittleren Abstand von zwischen 0,5 und 5 cm, insbesondere 2,5 bis 4 cm aufweisen.By a suitable choice of the angle, the closure device can be adapted and optimized to different parameters such as bag geometry or dimensioning, inflow angle of an air flow during operation. A closure surface opposite the inlet opening may in particular have a spacing therefrom or an average spacing of between 0.5 and 5 cm, in particular 2.5 to 4 cm.

Die wenigstens eine Verschlussfläche kann eine größere Fläche als die Fläche der Eintrittsöffnung aufweisen. Auf diese Weise wird ein sicheres und dichtes Verschließen der Einlassöffnung gesichert. Jede Verschlussfläche kann eine Fläche von 15 bis 100 cm2, insbesondere 40 bis 60 cm2 aufweisen.The at least one closure surface may have a larger area than the area of the inlet opening. In this way, a secure and tight closure of the inlet opening is ensured. Each closure surface may have an area of 15 to 100 cm 2 , in particular 40 to 60 cm 2 .

Erfindungsgemäß weist die Verschlussvorrichtung in der zweiten Stellung zwei trapezförmige oder rechteckige Verschlussflächen auf, die, ausgehend von der Einlassöffnung, keilförmig aufeinander zulaufen und an einer der Einlassöffnung gegenüberliegenden Verbindungskante miteinander verbunden sind.According to the invention, the closure device in the second position has two trapezoidal or rectangular closure surfaces which, starting from the inlet opening, run in a wedge shape towards one another and are connected to one another at a connection edge opposite the inlet opening.

Alternativ hierzu weist die Verschlussvorrichtung erfindungsgemäß in der zweiten Stellung die Form eines Parallelepipeds, insbesondere eines Quaders, auf, der in einer ersten, die Einlassöffnung umgebenden und mit der Beutelinnenseite verbundenen Seitenfläche eine Einströmöffnung und in wenigstens einer auf der ersten Seitenfläche stehenden weiteren Seitenfläche eine Ausströmöffnung aufweist.Alternatively, the closure device according to the invention in the second position, the shape of a parallelepiped, in particular a cuboid, on in a first, the inlet opening surrounding and connected to the bag inner side side surface has an inflow opening and in at least one standing on the first side surface further side surface an outflow opening.

Durch die Parallelepipedform wird ein stabiler Aufbau der Verschlussvorrichtung erzielt, wobei gleichzeitig eine geeignete Verschlussfläche durch die der Einströmöffnung gegenüberliegende Seitenfläche des Parallelepipeds gebildet wird.The parallelepiped shape achieves a stable construction of the closure device, at the same time a suitable closure surface being formed by the side surface of the parallelepiped opposite the inflow opening.

Dabei kann insbesondere jede Ausströmöffnung die gesamte Seitenfläche des Parallelepipeds einnehmen. Damit wird vermieden, dass sich in einer Ecke des Parallelepipeds eingesaugte Staubpartikel ansammeln.In this case, in particular, each discharge opening occupy the entire side surface of the parallelepiped. This prevents dust particles that have accumulated in a corner of the parallelepiped from accumulating.

Insbesondere können wenigstens zwei sich gegenüberliegende Ausströmöffnungen vorgesehen sein. Durch diese wenigstens zwei gegenüberliegende Ausströmöffnungen wird erreicht, dass ein einströmender Luftstrom in homogener Weise in den Staubsaugertlterbeutel aus der Verschlussvorrichtung ausströmen kann.In particular, at least two opposing outflow openings can be provided. By means of these at least two opposite outflow openings, it is achieved that an inflowing airflow can flow out of the closure device in a homogeneous manner into the vacuum cleaner bag.

In einer Weiterbildung der zuvor beschriebenen Staubsaugerfilterbeutel kann die Verschlussvorrichtung derart ausgebildet sein, dass in der zweiten Stellung ein durch die Einlassöffnung eintretender Luftstrom ablenkbar ist.In a further development of the previously described vacuum cleaner filter bags, the closure device can be designed such that in the second position, an air flow entering through the inlet opening can be deflected.

Es hat sich herausgestellt, dass mit einer Verschlussvorrichtung, die auf diese Weise auch die Funktion einer Ablenkvorrichtung übernimmt, die Standzeit eines Staubsaugerfilterbeutels bei hervorragenden Filtereigenschaften signifikant erhöht ist. Insbesondere wurde festgestellt, dass der sich in einem Filterbeutel bildende Filterkuchen erheblich zum Filtrationsverhalten des Filterbeutels beiträgt. Durch eine derartige Verschlussvorrichtung wird ein durch die Einlassöffnung eintretender Luftstrom abgelenkt, so dass die mitgeführten Partikel gleichmäßig im Beutelinnem verteilt werden und folglich eine gleichmäßige Verteilung des sich bildenden Filterkuchens und damit eine erhöhte Standzeit erhalten wird.It has been found that with a closure device, which thus assumes the function of a deflection device, the service life of a vacuum cleaner filter bag is significantly increased with excellent filter properties. In particular, it has been found that the filter cake forming in a filter bag contributes significantly to the filtration behavior of the filter bag. Such a closure device deflects an air flow entering through the inlet opening, so that the entrained particles are distributed uniformly in the interior of the bag, and consequently a uniform distribution of the forming filter cake and thus an increased service life is obtained.

Eine solche Verschlussvorrichtung hat weiterhin den Vorteil, dass die im Luftstrom mitgeführten Partikel nicht ungehindert und mit großer Geschwindigkeit auf die der Einlassöffnung gegenüberliegende Beutelwand prallen und diese zerstören.Such a closure device has the further advantage that the entrained particles in the air flow do not bounce unhindered and at high speed on the bag wall opposite the inlet opening and destroy it.

Insbesondere kann die Verschlussvorrichtung zum Aufteilen des Luftstroms in wenigstens zwei Teilströme mit unterschiedlichen Strömungsrichtungen ausgebildet ist.In particular, the closure device for dividing the air flow into at least two partial streams may be formed with different flow directions.

Durch eine derartige Aufteilung in zwei oder mehr Teilströme wird eine noch homogenere Verteilung des Filterkuchens erreicht. Außerdem ist die Zahl der Partikel pro Teilchenstrom im Vergleich mit dem eintretenden Luftstrom verringert, was die Belastung der Beutelwände durch die einzelnen Teilströme reduziert.By such a division into two or more partial flows even more homogeneous distribution of the filter cake is achieved. In addition, the number of particles per particle flow is reduced in comparison with the incoming air flow, which reduces the burden of the bag walls by the individual partial flows.

Die Erfindung stellt weiterhin einen Staubsauger zur Aufnahme eines der zuvor beschriebenen Staubsaugerfilterbeutel bereit, in dem eine Halteeinrichtung, die an der Halteplatte des Staubsaugerfilterbeutels anbringbar ist, angeordnet ist, wobei die Halteeinrichtung derart ausgebildet und/oder in dem Gehäuse angeordnet ist, dass durch ein Anbringen der Halteplatte mit der Halteeinrichtung die Verschlussvorrichtung des Staubsaugerfilterbeutels die Einlassöffnung die zweite Stellung einnimmt. Außerdem wird auch eine Kombination aus einem der zuvor beschriebenen Staubsaugerfilterbeutel und einem derartigen Staubsauger bereitgestellt.The invention further provides a vacuum cleaner for receiving one of the previously described vacuum cleaner filter bags, in which a holding device, which is attachable to the holding plate of the vacuum cleaner filter bag, is arranged, wherein the holding device is formed and / or arranged in the housing that by attaching the holding plate with the holding device, the closure device of the vacuum cleaner filter bag, the inlet opening occupies the second position. In addition, a combination of one of the above-described vacuum cleaner filter bags and such a vacuum cleaner is also provided.

Ein solcher Staubsauger ermöglicht ein vorteilhaftes Zusammenwirken mit den beschriebenen Staubsaugerfilterbeuteln.Such a vacuum cleaner allows an advantageous interaction with the described vacuum cleaner filter bags.

Zusätzlich wird ein Staubsauger mit einer Halteeinrichtung für die Halteplatte eines Staubsaugerfilterbeutels bereitgestellt, wobei der Staubsaugerfilterbeutel eine im im Bereich der Einlassöffnung angeordnete Verschlussvorrichtung aufweist, die derart ausgebildet ist, dass in einer ersten Stellung der Verschlussvorrichtung die Einlassöffnung verschlossen und in einer zweiten Stellung geöffnet ist, und mit einer Öffnungseinrichtung, die derart ausgebildet ist, dass sie in einer ersten Stellung der Verschlussvorrichtung ein Einnehmen ihrer ersten Stellung erlaubt und in einer zweiten Stellung derart mit der Verschlussvorrichtung zusammenwirkt, dass diese ihre zweite Stellung einnimmt.In addition, a vacuum cleaner is provided with a holding device for the holding plate of a vacuum cleaner filter bag, the vacuum cleaner filter bag having a closure device arranged in the region of the inlet opening, which is designed such that in a first position of the closure device the inlet opening is closed and opened in a second position, and with an opening device, which is designed such that, in a first position of the closure device, it allows it to assume its first position and, in a second position, interacts with the closure device in such a way that it occupies its second position.

Durch diese zwei Stellungen der Öffnungseinrichtung kann die Einlassöffnung des Staubsaugerfilterbeutels in geeigneter Weise geöffnet und geschlossen werden.Through these two positions of the opening device, the inlet opening of the vacuum cleaner filter bag can be opened and closed in a suitable manner.

Insbesondere kann die Öffnungseinrichtung derart ausgebildet sein, dass sie im ausgeschalteten Zustand des Staubsaugers ihre erste Stellung einnimmt und beim Einschalten des Staubsaugers die zweite Stellung einnimmt. Damit wird der Beutel beim Einschalten des Staubsaugers geöffnet und beim Ausschalten wieder geschlossen.In particular, the opening device can be designed such that it assumes its first position when the vacuum cleaner is switched off and occupies the second position when the vacuum cleaner is switched on. Thus, the bag is opened when you turn on the vacuum cleaner and closed when you turn off.

Dies vermeidet insbesondere ein Austreten der im Beutel befindlichen Partikel solange der Beutel nicht im Betrieb ist.This avoids in particular leakage of particles in the bag as long as the bag is not in operation.

Alternativ kann die Öffnungseinrichtung auch derart ausgebildet sein, dass bei geöffnetem Staubsaugerfilterbeutelfach des Staubsaugers ihre erste Stellung einnimmt und bei geschlossenem Staubsaugerfilterbeutelfach ihre zweite Stellung einnimmt.Alternatively, the opening device may also be designed such that when the vacuum cleaner filter bag compartment of the vacuum cleaner is open assumes its first position and occupies its second position when the vacuum cleaner filter bag compartment is closed.

Figur 1 zeigt schematisch einen Querschnitt durch ein Ausführungsbeispiel einer erfindungsgemäßen Verschlussvorrichtung. In dieser Figur nimmt die Verschlussvorrichtung ihre zweite Stellung ein, in der sie, im Vergleich mit der in Figur 2 gezeigten zweiten Stellung eine geringere Ausdehnung senkrecht zur Ebene der Einlassöffnung aufweist. FIG. 1 schematically shows a cross section through an embodiment of a closure device according to the invention. In this figure, the closure device assumes its second position, in which it, in comparison with the in FIG. 2 shown second position has a smaller extent perpendicular to the plane of the inlet opening.

Im Innern eines Staubsaugerfilterbeutels 1 ist im Bereich der (kreisförmigen) Einlassöffnung 3 eine Verschlussvorrichtung 2 angeordnet. Außen an dem Staubsaugerfilterbeutel ist eine Halteplatte 4 vorgesehen.Inside a vacuum cleaner filter bag 1, a closure device 2 is arranged in the region of the (circular) inlet opening 3. Outside of the vacuum cleaner filter bag, a holding plate 4 is provided.

In dem gezeigten Beispiel ist die Verschlussvorrichtung 2 in ihrer zweiten Stellung in Form eines Quaders ausgebildet. Die Grundfläche 5 dieses Quaders ist parallel zur Ebene der Einlassöffnung 3 angeordnet. Diese Grundfläche ist die Verschlussfläche für die Einlassöffnung.In the example shown, the closure device 2 is formed in its second position in the form of a cuboid. The base 5 of this cuboid is parallel to Level of the inlet opening 3 is arranged. This base area is the closure surface for the inlet opening.

Im Innern der Verschlussvorrichtung ist ein erstes Dichtungselement 8 angeordnet. Dieses Dichtungselement ist um die gesamte Einlassöffnung herum vorgesehen. Durch dieses Dichtungselement wird insbesondere eine geeignete Abdichtung nach Einführen eines Stutzens, der mit dem Staubsaugerschlauch verbunden ist, erzielt.In the interior of the closure device, a first sealing element 8 is arranged. This sealing element is provided around the entire inlet opening. By means of this sealing element, in particular, a suitable seal is achieved after insertion of a connecting piece which is connected to the vacuum cleaner hose.

Ein weiteres Dichtungselement 9 ist auf der Grundfläche 5 des Quaders angeordnet. Dieses dient dazu, die Einlassöffnung in der ersten Stellung der Verschlussvorrichtung dicht zu verschließen. Das weitere Dichtungselement 9 kann insbesondere an die Öffnung in dem ersten Dichtungselement 8 angepasst sein.Another sealing element 9 is arranged on the base 5 of the cuboid. This serves to tightly close the inlet opening in the first position of the closure device. The further sealing element 9 can be adapted in particular to the opening in the first sealing element 8.

Beispielsweise lassen sich die beiden Dichtungselemente 8 und 9 herstellen, indem ein durchgehendes, d.h. die Einlassöffnung überdeckendes, Dichtungsmaterial im Innern der Verschlussvorrichtung angeordnet wird. Dabei kann es sich beispielsweise um einen geschlossenzelligen Schaum handeln. Danach wird im Bereich der Einlassöffnung eine Öffnung aus dem Dichtungsmaterial ausgestanzt, um eine Einströmöffnung in den Quader freizulegen. Das ausgestanzte Material kann dann an der Grundfläche 5 des Quaders angeordnet sein, so dass es in der ersten Stellung der Verschlussvorrichtung genau in die Öffnung in dem Dichtungselement 8 passt. Vor dem Ausstanzen kann das auszustanzende Material bereits mit der Grundfläche verbunden, insbesondere verklebt, werden. Damit ist dieses Material nach dem Ausstanzen bereits an der richtigen Position angeordnet.For example, the two sealing elements 8 and 9 can be made by using a continuous, i. the inlet opening overlapping, sealing material is disposed inside the closure device. This may be, for example, a closed-cell foam. Thereafter, in the region of the inlet opening, an opening is punched out of the sealing material in order to expose an inflow opening in the cuboid. The stamped-out material can then be arranged on the base 5 of the cuboid, so that in the first position of the closure device it fits exactly into the opening in the sealing element 8. Before punching out the material to be punched out can already be connected to the base surface, in particular adhesively bonded. Thus, this material is already arranged in the correct position after punching.

Weiterhin ist dem gezeigten Ausführungsbeispiel eine Biegefeder 7, die beispielsweise bombiert sein kann, vorgesehen. Durch die Federkraft wird eine Rückstellkraft auf die Verschlussvorrichtung ausgeübt, so dass diese grundsätzlich ihre in Figur 1 gezeigte geschlossene Stellung einnimmt.Furthermore, the embodiment shown, a bending spring 7, which may be, for example, cambered provided. By the spring force, a restoring force is exerted on the closure device, so that they basically their in FIG. 1 shown closed position occupies.

Die Biegefeder 7 kann beispielsweise mit der Grundfläche und der rechten Seitenfläche verklebt sein. Die Feder kann auch in anderer Weise angeordnet sein. Beispielsweise kann die Verschlussvorrichtung 2 wenigstens teilweise doppellagig (bspw. mit zwei Lagen aus Pappe) ausgebildet sein, wobei die Feder zwischen den beiden Lagen angeordnet ist. Die Lagen sind miteinander verklebt, wobei für die Feder ein nicht verklebter Zwischenraum freigelassen wird; die Feder selbst braucht dann nicht mit einer der Lagen verklebt zu sein; alternativ kann sie auch nur an einem Ende mit einer der oder beiden Lagen fest verbunden sein.The bending spring 7 may be glued, for example, with the base and the right side surface. The spring can also be arranged in another way. For example, the closure device 2 may be at least partially double-layered (for example, with two layers of cardboard), wherein the spring between the two layers is arranged. The layers are glued together leaving a non-bonded gap for the spring; the spring itself then need not be glued to one of the layers; Alternatively, it may also be firmly connected to one or both layers only at one end.

Es ist zu betonen, dass, je nach Ausführung der Feder 7 und/oder des Aufbaus der Verschlussvorrichtung, das Dichtungselement 9 in der ersten Stellung der Verschlussvorrichtung unterschiedlich weit in die Öffnung des Dichtungselements 8 eindringen kann.It should be emphasized that, depending on the design of the spring 7 and / or the construction of the closure device, the sealing element 9 in the first position of the closure device can penetrate different degrees into the opening of the sealing element 8.

Alternativ zu der Biegefeder kann auch ein Permanentmagnet in oder an der Halteplatte 4 und ein ferromagnetisches Element in oder an einer der Seitenflächen oder der Grundfläche 5 vorgesehen sein. Damit wird ebenfalls eine Rückstelleinrichtung gebildet, die ein Zusammenlegen der Verschlussvorrichtung ermöglicht.As an alternative to the spiral spring, a permanent magnet can also be provided in or on the retaining plate 4 and a ferromagnetic element in or on one of the side surfaces or the base 5. Thus, a return device is also formed, which allows a folding of the closure device.

Wie sich aus Figur 2 ergibt, kann die Halteplatte 4 an einer Halteeinrichtung 10 eines Staubsaugers angebracht werden. Eine Draufsicht auf eine derartige Anordnung ist in Figur 3 gezeigt. Die Halteeinrichtung 10 kann insbesondere eine Aufnahme für die Halteplatte 4 aufweisen.As it turned out FIG. 2 results, the holding plate 4 can be attached to a holding device 10 of a vacuum cleaner. A plan view of such an arrangement is shown in FIG FIG. 3 shown. The holding device 10 may in particular have a receptacle for the holding plate 4.

Beim Anbringen der Halteplatte 4 an der Halteeinrichtung 10 wird die in ihrer ersten Stellung (siehe Figur 1) zusammengeklappte Verschlussvorrichtung nach rechts (in der Ansicht der Figuren) geklappt, so dass die Verschlussvorrichtung ihre zweite Stellung einnimmt und die Einlassöffnung geöffnet wird. In dem in Figur 2 gezeigten Beispiel stößt der Staubsaugerfilterbeutel 1 derart an eine Fläche 11 des Staubsaugers, dass - gegen die Federkraft der Biegefeder - die Verschlussvorrichtung nach rechts bewegt wird, woraus ein Aufklappen der Verschlussvorrichtung in ihre Quadergestalt resultiert.When attaching the holding plate 4 to the holding device 10 is in its first position (see FIG. 1 ) folded closure device to the right (in the view of the figures) folded, so that the closure device assumes its second position and the inlet opening is opened. In the in FIG. 2 the example shown, the vacuum cleaner filter bag 1 abuts a surface 11 of the vacuum cleaner, that - against the spring force of the bending spring - the closure device is moved to the right, resulting in an unfolding of the closure device into its cuboid shape.

Die Verschlussvorrichtung muss also derart dimensioniert und, insbesondere bezüglich der Halteplatte, im Staubsaugerfilterbeutel angeordnet sein, dass das Einnehmen der zweiten Stellung ermöglicht wird.The closure device must therefore be dimensioned in such a way and, in particular with respect to the holding plate, arranged in the vacuum cleaner filter bag so that the taking in of the second position is made possible.

Aufgrund dieser Konstruktion ist es nicht erforderlich, eine Feder mit einer genau bestimmten Federkennlinie zu verwenden. Es genügt, dass sie eine erste und eine zweite Stellung ermöglicht; die Kraft zum Aufklappen des Quaders wird durch das Anbringen der Halteplatte an der Halteeinrichtung aufgebracht. Bei einem Entfernen der Halteplatte von der Halteeinrichtung wirkt die Rückstellkraft der Feder so, dass die Verschlussvorrichtung in ihre erste Stellung geklappt wird und die Einlassöffnung verschließt.Because of this construction, it is not necessary to use a spring with a well-defined spring characteristic. It is sufficient that she allows a first and a second position; the force for unfolding the cuboid is applied by attaching the holding plate to the holding device. Upon removal of the retaining plate from the holding device, the restoring force of the spring acts so that the closure device is folded into its first position and closes the inlet opening.

Das Aufklappen in die geöffnete Stellung kann beispielsweise durch eine geeignete Anordnung der Halteeinrichtung in dem Staubsauger, so dass eine entsprechende Fläche des Staubsaugers zum Aufklappen vorhanden ist, oder durch eine entsprechende Ausbildung der Halteeinrichtung selbst, so dass nur durch diese ein Aufklappen erfolgt, erzielt werden. Weiterhin können auch Öffnungseinrichtungen im Staubsauger vorgesehen sein, die ein Aufklappen der Verschlussvorrichtung verursachen können.The unfolding in the open position, for example, by a suitable arrangement of the holding device in the vacuum cleaner, so that a corresponding surface of the vacuum cleaner is available for unfolding, or by a corresponding design of the holding device itself, so that only by this unfolding is achieved , Furthermore, opening devices may also be provided in the vacuum cleaner, which may cause the closure device to open.

Die Grundfläche 5 erfüllt weiterhin die Funktion einer Ablenkfläche oder Prallplatte. Zwei der Seitenflächen senkrecht zur Grundfläche weisen jeweils eine Ausströmöffnung auf (in der gezeigten Ansicht vome und hinten), die jeweils die gesamte Seitenfläche des Quaders einnehmen. Die beiden anderen Seitenflächen (links und rechts in der gezeigten Ansicht) sind geschlossen. Somit wird ein durch die Einlassöffnung 3 eintretender Luftstrom in zwei Teilströme aufgeteilt, die relativ zur Einströmöffnung um 90° abgelenkt sind und nach hinten bzw. vorne in den Beutel strömen. Durch diese Ablenkfunktion wird eine homogene Verteilung des Filterkuchens erreicht, was die Standzeit bei hervorragenden Filtereigenschaften erhöht.The base 5 also fulfills the function of a deflection surface or baffle plate. Two of the side surfaces perpendicular to the base surface each have an outflow opening (in the view shown vome and back), each occupy the entire side surface of the cuboid. The two other side surfaces (left and right in the view shown) are closed. Thus, an airflow entering through the inlet port 3 is divided into two sub-streams which are deflected by 90 ° relative to the inflow port and flow backwards or forwards into the bag. Through this deflection function, a homogeneous distribution of the filter cake is achieved, which increases the service life with excellent filter properties.

Die Abmessungen der quaderförmigen Ablenkvorrichtungen können beispielsweise 7,5 cm x 8 cm x 3 cm (Breite x Tiefe x Höhe) betragen. Das Material kann beispielsweise Pappe sein.The dimensions of the cuboid baffles can be, for example, 7.5 cm × 8 cm × 3 cm (width × depth × height). The material may be cardboard, for example.

Das gezeigte Ausführungsbeispiel lässt sich in vielfältiger Weise modifizieren.The embodiment shown can be modified in many ways.

Beispielsweise ist es möglich, nur in einer oder in drei oder in allen Seitenflächen des Quaders eine Ausströmöffnung vorzusehen. Auch die Abmessungen und die Materialien können anders gewählt werden.For example, it is possible to provide an outflow opening only in one or in three or in all side surfaces of the cuboid. The dimensions and the materials can be chosen differently.

Weiterhin kann auch nur ein Dichtungselement vorgesehen sein, dass auf der Grundfläche des Quaders so angeordnet ist, dass die Einströmöffnung des Quaders in der ersten Stellung der Verschlussvorrichtung abgedichtet wird. Hierfür kann beispielsweise das aus der (der Grundfläche gegenüberliegende) Deckfläche des Quaders gestanzte Materialstück, wodurch die Einströmöffnung erzeugt wird, verwendet werden. Während der Herstellung kann insbesondere die Einströmöffnung nicht vollständig ausgestanzt werden, sondern es kann ein kleiner Materialsteg verbleiben. Beim Ausbilden der Quaderform, beispielsweise durch Falten und Kleben, wird das (teilweise) ausgestanzte Materialstück mit der Grundfläche verklebt und der Steg anschließend durchtrennt.Furthermore, only one sealing element can be provided that is arranged on the base surface of the cuboid so that the inflow opening of the cuboid is sealed in the first position of the closure device. For this purpose, for example, from the (the base surface opposite) top surface of the cuboid punched piece of material, whereby the inflow opening is generated, can be used. During manufacture, in particular, the inflow opening can not be completely punched out, but rather a small material web can remain. When forming the cuboid shape, for example by folding and gluing, the (partially) punched piece of material is glued to the base and then the web is severed.

Alternativ kann die Grundfläche auch derart geprägt sein, dass eine in das Innere der Verschlussvorrichtung ragende Erhebung ausgebildet wird, durch die ebenfalls die Einlassöffnung abgedichtet werden kann.Alternatively, the base can also be embossed such that a protruding into the interior of the closure device survey is formed, through which also the inlet opening can be sealed.

Bei der in Figur 2 gezeigten Quaderform kann weiterhin beispielsweise die Deckfläche eine im Vergleich mit der Grundfläche größere Fläche aufweisen; insbesondere kann die Deckfläche die Grundfläche an den offenen, d.h. mit den Ausströmöffnungen, Seiten um 2 - 3 mm überragen. Diese zusätzlichen Flächen können nach unten geknickt werden, um bei einem Zusammenklappen der Verschlussvorrichtung ein Abdichten der offenen Seiten zu ermöglichen.At the in FIG. 2 Furthermore, for example, the top surface shown may have a larger area compared to the base surface; In particular, the top surface may project beyond the base area at the open, ie with the outflow openings, sides by 2 to 3 mm. These additional surfaces can be folded down to allow sealing of the open sides when the closure device collapses.

Die Beutelwand des Staubsaugerfilterbeutels kann beispielsweise einen Aufbau, wie in der EP 0 960 645 beschrieben, aufweisen. Insbesondere kann eine Grobfilterschicht, beispielsweise aus einem Meltblown, in Strömungsrichtung aus dem Innern des Beutels nach außen vor einer Feinfilterschicht, beispielsweise ebenfalls aus einem Meltblown, angeordnet sein. Zusätzlich können in der Filterstruktur noch weitere Schichten vorgesehen sein, beispielsweise Stützschichten und/oder geruchsabsorbierende Schichten.The bag wall of the vacuum cleaner filter bag, for example, a structure, as in EP 0 960 645 described, have. In particular, a coarse filter layer, for example from a meltblown, can be arranged in the flow direction from the interior of the bag to the outside in front of a fine filter layer, for example likewise from a meltblown. In addition, further layers may be provided in the filter structure, for example support layers and / or odor-absorbing layers.

In dem gezeigten Beispiel kann die Verschlussvorrichtung in unterschiedlicher Weise mit der Beutelinnenseite verbunden sein. Gemäß einer Möglichkeit wird die Verschlussvorrichtung mit der Beutelinnenwand verklebt. Alternativ kann die Oberseite einer Verschlussvorrichtung, die beispielsweise aus Pappe ist, mit PP (Polypropylen) beschichtet sein, sodass bei einem Anschweißen einer PP-Halteplatte mittels Ultraschall auch gleichzeitig die Verschlussvorrichtung mit der Beutelwand verschweißt wird.In the example shown, the closure device may be connected in different ways to the inside of the bag. According to one possibility, the closure device is glued to the bag inner wall. Alternatively, the top of a closure device, which is for example made of cardboard, be coated with PP (polypropylene), so that when welding a PP holding plate by means of ultrasound and the closure device is simultaneously welded to the bag wall.

Alternativ zu der beschriebenen Quadergestalt kann die Verschlussvorrichtung auch keilförmige oder keilähnliche Gestalt aufweisen.As an alternative to the described cuboid shape, the closure device may also have a wedge-shaped or wedge-like shape.

Die Verschlussvorrichtung kann auch so ausgebildet sein, dass sie keine Ablenkfunktion erfüllt. Beispielsweise kann sie als um eine senkrecht zur Ebene der Einlassöffnung angeordnete Achse schwenkbare Verschlussplatte ausgebildet sein, die beim Anbringen der Halteplatte an einer Halteeinrichtung von der Einlassöffnung weggeschwenkt wird. Als Federelement kann hier beispielsweise eine Spiralfeder vorgesehen sein. In dieser Ausführung bleibt die Ausdehnung der Verschlussvorrichtung in beiden Stellungen im wesentlichen gleich.The closure device can also be designed such that it does not fulfill a deflection function. For example, it may be formed as a pivotable closure plate about an axis arranged perpendicular to the plane of the inlet opening, which is pivoted away from the inlet opening during attachment of the holding plate to a holding device. As a spring element can be provided here, for example, a coil spring. In this embodiment, the extent of the closure device remains substantially the same in both positions.

Alle oben stehend unter Bezugnahme auf Fig. 1 - 3 beschriebenen Ausführungsformen lassen sich gemäß einer zweiten konstruktiven Alternative so abwandeln, dass die Verschlussvorrichtung nicht an der Beutelinnenseite im Bereich der Einlassöffnung angebracht ist, sondern der Staubsaugerfilterbeutel eine Halteplatte zur Halterung des Beutels in einem Staubsauger umfasst, an der die Verschlussvorrichtung angeordnet ist.All of the above with reference to Fig. 1-3 described embodiments can be modified according to a second constructive alternative so that the closure device is not attached to the inside of the bag in the region of the inlet opening, but the vacuum cleaner filter bag comprises a holding plate for holding the bag in a vacuum cleaner on which the closure device is arranged.

Gemäß einer ersten Ausführungsform dieser zweiten konstruktiven Alternative ist hierzu in der Beutelwand eine Montageöffnung vorzusehen, die so groß ist, dass die an der Halteplatte befestigte Verschlussvorrichtung durch die Montageöffnung in den Staubsaugerfilterbeutel so eingeführt werden kann, dass sie beim Betrieb des Staubsaugers die oben beschriebenen Funktionen und Wirkungen zeigt.According to a first embodiment of this second constructive alternative for this purpose, a mounting opening is provided in the bag wall, which is so large that the closure device attached to the retaining plate can be inserted through the mounting hole in the vacuum cleaner filter bag so that they have the functions described above during operation of the vacuum cleaner and effects.

Ein Beispiel für diese Ausführungsform ist in Fig. 4 schematisch illustriert, wobei gleiche Elemente mit gleichen Bezugszeichen versehen sind.An example of this embodiment is in Fig. 4 schematically illustrated, wherein like elements are provided with the same reference numerals.

In dieser Ausführungsform wird die Verschlussvorrichtung 2 in einer geöffneten Stellung in den Beutel 1 eingebracht und die Halteplatte 4 mit der Beutelaußenseite verbunden. Dabei muss die Halteplatte etwas größer als die Montageöffnung sein, so dass sie an der Beutelaußenwand an dieser befestigt werden kann.In this embodiment, the closure device 2 is inserted in an open position in the bag 1 and the holding plate 4 is connected to the bag outside. The retaining plate must be slightly larger than the mounting hole so that it can be attached to the bag outer wall of this.

Vorzugsweise ist die Befestigung hierbei derart, dass sie die Halteplatte 4 dicht gegenüber dem Staubsaugerfilterbeutel 1 befestigt. Die Art der Befestigung wird hierbei abhängig von dem Material des Staubsaugerfilterbeutels und der Halteeinrichtung gewählt. Beispielsweise aber nicht ausschließlich können Beutelwand und Verschlussvorrichtung verklebt oder verschweißt werden, insbesondere durch Ultraschall.Preferably, the attachment is in this case such that it fixes the holding plate 4 close to the vacuum cleaner filter bag 1. The type of attachment is chosen depending on the material of the vacuum cleaner filter bag and the holding device. For example, but not exclusively, bag wall and closure device can be glued or welded, in particular by ultrasound.

In dem gezeigten Ausführungsbeispiel ist die Feder 7 zwischen zwei Aufnahmeelemente 10 geklemmt. Eine solche Anordnung ist besonders bei Verschlussvorrichtungen aus Kunststoff von Vorteil. Ein Verkleben der Feder 7 ist hier nicht erforderlich, so dass die Feder frei bewegbar angeordnet ist und nur durch die Aufnahmeelemente 10 gehalten wird.In the embodiment shown, the spring 7 is clamped between two receiving elements 10. Such an arrangement is particularly advantageous in closure devices made of plastic. Gluing the spring 7 is not required here, so that the spring is arranged freely movable and is held only by the receiving elements 10.

In dieser Ausführungsform ist die Eintrittsöffnung in der Halteplatte ausgebildet und bevorzugt mit einer Dichtung 8 versehen, so dass ein luftdichter Abschluss zwischen Eintrittsstutzen des Staubsaugers und Staubsaugertlterbeutel gewährleistet ist. Je nach verwendetem Material der Halteplatte können hierzu Dichtungen aus Gummi, Schaum oder ähnlich geeigneten Materialen verwendet werden.In this embodiment, the inlet opening is formed in the holding plate and preferably provided with a seal 8, so that an airtight seal between the inlet nozzle of the vacuum cleaner and vacuum cleaner bag is guaranteed. Depending on the material used, the retaining plate can be used for this purpose seals made of rubber, foam or similar suitable materials.

Abgesehen von den besonderen durch die zweite konstruktive Alternative bedingten Merkmalen kann der Staubsaugerfilterbeutel so ausgebildet werden wie unter Bezug auf die erste konstruktive Alternative beschrieben wurde. Insbesondere kann auch die Verschlussvorrichtung auf verschiedenste Weise, insbesondere wie oben im Zusammenhang mit der ersten konstruktive Alternative beschrieben, ausgebildet werden.Apart from the particular features due to the second design alternative, the vacuum cleaner filter bag can be formed as described with reference to the first constructive alternative. In particular, the closure device can also be designed in various ways, in particular as described above in connection with the first constructive alternative.

Entsprechend einer zweiten Ausführungsform der zweiten konstruktiven Alternative kann in der Beutelwand eine Montageöffnung vorgesehen werden, die so groß ist, dass sich die Verschlussvorrichtung für sich genommen an der Beutelaußenseite befestigen lässt. Auch hierfür werden für die verwendeten Materialen des Staubsaugerfilterbeutels und der Verschlussvorrichtung geeignete Verbindungen gewählt, wie Verkleben oder Verschweißen.According to a second embodiment of the second design alternative, a mounting opening can be provided in the bag wall, which is so large that the closure device can be attached to the outside of the bag taken alone. Also for this are used for the materials used in the vacuum cleaner filter bag and the closure device selected suitable connections, such as gluing or welding.

Auf die Verbindung zwischen Verschlussvorrichtung und Staubsaugerfilterbeutel wird schließlich eine Halteplatte entsprechender Größe aufgesetzt und an der Kombination Verschlussvorrichtung und Staubsaugerbeutel befestigt. Hierdurch wird wiederum die Verschlussvorrichtung an der Halteplatte angeordnet.On the connection between the closure device and vacuum cleaner filter bag finally a holding plate of appropriate size is placed and attached to the combination closure device and vacuum cleaner bag. As a result, in turn, the closure device is arranged on the holding plate.

Die Merkmale des StaubsaugerFlterbeutels, die mit der speziellen konstruktiven Ausgestaltung nichts zu tun haben, können wiederum auf vielfältigste Weise, wie sie insbesondere unter Bezugnahme auf die verschiedenen Ausführungsformen der ersten konstruktiven Alternative und im Zusammenhang mit der ersten Ausführungsform der zweiten konstruktiven Alternative beschrieben sind, ausgebildet werden.The features of the vacuum cleaner bag, which have nothing to do with the specific structural design, in turn, in a variety of ways, as described in particular with reference to the various embodiments of the first constructive alternative and in connection with the first embodiment of the second constructive alternative formed become.

Gemäß einer dritten Ausführungsform der zweiten konstruktiven Alternative wird die Halteplatte aus Kunststoff hergestellt. In diesem Zusammenhang bietet es sich an, die Verschlussvorrichtung als integralen Bestandteil der Halteplatte auszubilden, so dass die Verschlussvorrichtung wiederum an der Halteplatte angeordnet ist. Zweckmäßigerweise werden die Formen von Halteplatte und Verschlussvorrichtung hierbei so gewählt, dass sie sich durch ein Spritzgussverfahren herstellen lassen.According to a third embodiment of the second constructive alternative, the holding plate is made of plastic. In this context, it makes sense to form the closure device as an integral part of the holding plate, so that the closure device is in turn arranged on the holding plate. Conveniently, the shapes of the holding plate and closure device are chosen so that they can be produced by an injection molding process.

Alternativ zur dritten Ausführung können in einer vierten Ausführungsform Haltevorrichtung und Verschlussvorrichtung auch einzeln durch ein Spritzgussverfahren gebildet werden und dann in geeigneter Weise aneinander befestigt werden.As an alternative to the third embodiment, in a fourth embodiment, the holding device and closing device can also be formed individually by an injection molding process and then fastened to one another in a suitable manner.

Sowohl für die dritte als auch für die vierte Ausführungsform gilt in Bezug auf das Einsetzen in den Staubfilterbeutel und das Befestigen der Halteplatte mit Verschlussvorrichtung, in Bezug auf die zu wählenden Dimensionen und in Bezug auf die verwendeten Materialien das im Zusammenhang mit der ersten und zweiten Ausführungsform der zweiten konstruktiven Alternative Gesagte.For both the third and fourth embodiments, with respect to insertion into the dust filter bag and attachment of the retaining plate with closure device, with respect to the dimensions to be selected and with respect to the materials used, the same applies to the first and second embodiments The second constructive alternative said.
