  • the invention relates to a dust filter bag for a vacuum cleaner, with one made of a solid paper material, for example cardboard-paper material, existing Holding plate with which a dust bag, for example is adhesive bonded, which holding plate one sealable opening for an intake manifold Has vacuum cleaner, the opening with a separate Closure element is closable, which consists of a Open position, in a secondary arrangement to the opening, in a closed position is displaceable, the further Closure element on at least two layers of the solid paper material rests, at least in an open position.
  • a separate Closure element is closable, which consists of a Open position, in a secondary arrangement to the opening, in a closed position is displaceable, the further Closure element on at least two layers of the solid paper material rests, at least in an open position.
  • the bag-forming filter material is close to the edge attached a wide surface of the holding plate, preferably in sealing adhesive connection.
  • the bag body can be folded to save space by folding the Support plate in the plane of the wall-forming layers of the Bag body.
  • This is a dust filter bag known for example from DE-OS 2 407 478.
  • the separate locking tab there consists of a between two layers of the holding plate slidably guided Strip, which has a hole. At approximately congruent Position for opening the hole brought hole the socket of the intake pipe can be used there to be docked. If the dust filter bag is filled, is pulled on the locking tab and the not perforated part of the strip in the closed position for Brought opening. This prevents a kind of breathing movement when grasping the collapsible bag body.
  • EP-A 0 510 314 is a generic one Dust filter bag known, the opening from the outside with a locking tab having an insertion area is closable, which has a strip-shaped Connection tab is connected to a holding plate. It is provided that the locking tab in her Plug-in area is circular that the Connection strap formed with a smaller width is as the insertion area and that the insertion area a plurality of circular stripes Has insertion tabs.
  • NL-A 73 05 715 also discloses a dust filter bag with one made of a solid paper material Holding plate, the opening for an intake pipe with a separate closure element sealable is by the closure element from an open position in a secondary arrangement for opening in a closed position is shifted.
  • the holding plate of the dust filter bag from two layers a paper material is formed and that the closure element in an open position on this double Location rests.
  • the object of the invention is to provide an improved one Form dust filter bags.
  • the closure element on at least a double layer of solid Paper material rests, at least in an open position and at least in the area of the opening three layers of the solid paper material arranged one above the other are provided, being between the two A rubber ring seal in the lower layers in the opening area is composed.
  • the stability is a secure version of a rubber ring seal reached for the connecting piece of the vacuum cleaner.
  • the area of the opening does not only exist from the highly stable three-layer laminate, rather also realized that the closure element, for example.
  • a locking tab located only within the contours the holding plate, both in the open and in the closed position.
  • the rubber ring seal is a joint between the two lower layers thus also to accommodate the sealing element utilized.
  • the fixing of the sealing element can in the laminate fuse can be included by, for example an adhesive or hot-melt layer on the rubber ring seal co-registered to secure the position. There is no additional Fixing effort, such as at an overlying sealing film would be necessary. Therefore the rubber ring seal a rather narrow peripheral bond zone the stabilized composite material is sufficient through to the edge of the support plate. Because this edge in generally a certain contour to a corresponding one Storage area of the vacuum cleaner has for example, nose-like projections etc.
  • the latching opening is a circumferential one Snap opening added, so that not even a special one Targeted assignment of the locking tab required becomes.
  • the holding plate is continuously formed in three layers at the edge. The has the advantage of equal rights, i.e. completely tilt-free support of the holding plate in the device-side recording, but still the opening remain double-layered compared to remote area can, so layer material is available for other purposes stands, for example, from this residual material Foldable closure flap designed over the opening becomes.
  • the meaning is not exhausted the multi-layer, in particular three-layer, of the holding plate, by namely even a configuration of even independent meaning is opened in that the top layer also forms a bracket and that the retaining bracket surrounding or circumscribing the opening is trained. This bracket is in the use position of the dust filter bag forming a layer, but can be used for transport or as a pull-out aid swivel into a folding position for exercising related function.
  • a dust filter bag for example for a vacuum cleaner, which on the docking side with a hard part in shape a holding plate 1 completes. From the back surface 2 the actual bag 3 is glued on the edge.
  • the holding plate 1 consists of a cardboard paper material.
  • the holding plate 1 has a contour within which a closure member 10 (which will be discussed further below is explained) both in the open position (e.g. Fig. 1) as well as in the closed position (e.g. Fig. 10) is included.
  • a closure member 10 which will be discussed further below is explained
  • the open position also offers the second layer b is a full-surface support for the Closure element 10.
  • the bag 3 can be folded to save space. He let folded against the back surface 2 (see, for example, Figure 2).
  • the narrow sides 4 of the bag 3 are drawn in a V-shape. Holding plate side the inner fold branches into one Y-shaped branch, which on the corner zones of the narrow side the holding plate 1 runs out directed. Bottom side the bag 3 is closed by folding and gluing.
  • the fold-out bears the reference number 5.
  • the fixation of the open or mouth edge of the bag happens on the rear surface 2 of the holding plate 1 by angling the edge 6 there and gluing on said area 2.
  • the corresponding adhesive layer is designated with 7.
  • the basically rectangular holding plate 1 is continuous or mostly three-layer structure
  • the individual Layers of the same outline are labeled a, b, c.
  • the uppermost layer a from the bag forms the front surface 8 the holding plate 1.
  • the Intake pipe or socket not shown of the vacuum cleaner.
  • the individual layers a to c exist preferably from a single folded blank, either is zigzag on top of each other or by Wrapping a free layer between two others, so Folding two end positions against each other (see FIG. 6).
  • the individual layers a to c are to form an opening 9 broken. It is a circular Opening. Their center is in the at the same time the line of symmetry forming the plane of symmetry of the holding plate 1, the two halves of which are thus mirrored are.
  • Said opening 9 is by means of a locking tab 10 sealable from the outside.
  • the latter is an integral part the top layer a, that is, from its material section formed by cutting free.
  • a closure tab 10 can be the well-known aspiration of the dust-filled bag 3 by touching it reduce the volume reduction taking place, yes even avoid.
  • the free cut carries the Designation F.
  • the cardboard-paper material at least in the area of the opening 9 in three layers.
  • the three-layer laminate stabilizes the docking area for the suction pipe or the suction nozzle of the vacuum cleaner, but also has the essential advantage the convenient accommodation of a rubber ring seal 11 between the joint-forming contact surfaces of the lower two layers b and c.
  • the edging is from the Sectional representations are particularly clearly recognizable.
  • the rubber ring seal 11 is a highly elastic ring membrane, the clear diameter D1 is smaller than the clear diameter of the circular Opening D2.
  • it can also be a Corresponding sealing property plastic film act.
  • the radial clearance depth of the rubber ring seal corresponds about the width of the border between the Layers b and c. In the drawings is the bezel depth reproduced somewhat broader.
  • the clear diameter D1 of the rubber ring seal 11 is dimensionally above that of the intake pipe, not shown or intake manifold.
  • the lateral wall of the latter runs approximately in the middle of the free length of the Rubber sealing ring 11.
  • the remaining length or the remaining area of the holding plate 1 is at least two layers. This area is useful in relation to the uppermost layer a to form the locking tab 10 used. This way no one needs separate locking device manufactured and assigned to become. Goes to the corresponding sealing flap Free cutting or not essentially everywhere to the periphery of this layer, the basic thickness x remains nevertheless in the area of the closure flap 10 Receiving plate 1.
  • All of the locking tabs 10 also fold transversely to extend the long rectangular holding plate 1 lying hinge zone 12.
  • the latter is from a fold line educated.
  • the ease of folding can for example be increased by a perforation 13.
  • the center point P1 or center point of the opening 9 is at least as far from hinge zone 12 spaced like the center point P2 of the locking tab 10. Both lie on the line formed by the cutting lines Plane or line of symmetry.
  • the locking tab has 10 a long shield-like shape with am Free end of a curved edge 14. Its radius corresponds to that of the opening 9. The width y this locking tab 10 corresponds at most to that Diameter D2.
  • the circular arc Edge 14 has a locking lug 15.
  • This locking lug 15 In front of this locking lug 15 leave the top layer a cleared free area as access recess 16. The latter is about the size of a fingertip, so that you can easily touch the Can engage under latch 15 to the locking tab 10th from their immersion position in the uppermost position a into the Figure 4 fold down the closed position.
  • This closed position is locked. This is located at a congruent point with 15 a locking opening 17. This is formed in that an opening edge area the middle position b compared to the opening edges of the top (a) and bottom (c) and partially set back is. This means that between layers a and c in Area of the opening 9 formed a free space generally for holding the closure element, d. H. here the locking tab 10 is used.
  • latching nose 15 and latching opening 17 expediently designed semicircular. The locking force achieved is so large that even with downward Holding plate 1 of the dust filter bag no dirt particles can fall out of the interior of the bag 3. Aspiration is also significantly reduced.
  • the middle layer b a larger one assigned to the opening 9 Has recess as the top and bottom layers a, c.
  • the third layer c congruent to the locking opening 17 an outline corresponding Have bulge 18. This allows it because the high elasticity and flexibility of the rubber ring seal 11 that the latch 15 in this direction slightly evades, but due to the bulge 18 Free-stretched zone of the rubber ring seal 11 springs back becomes.
  • the middle layer b has a somewhat larger diameter than the diameter D2 of the uppermost (a) and lower layer c with a correspondingly concentric arrangement the diameter is. This leads to a larger area Undercut of the locking tab 10 when this has a correspondingly widened locking lug 15 or immersed with the entire edge 14 in a latching manner.
  • the rest i.e. of the Opening 9 facing away from the area of the holding plate 1 via the Formation of the locking tab 10 also for Creation of a bracket 19 is used.
  • the latter has a U-shape. Its U-web 20 is circular.
  • the subsequent ones, in the direction of the opening 9 parallel U-legs 21 are rooted in one Hinge zone 23. This also extends transversely to Length of the holding plate 1.
  • the hinge zones 23 are aligned with the hinge zone 12 of the locking tab 10.
  • the hinge zones 23 are also of fold lines of the blank and can also be perforated be.
  • bracket 19 With the bracket 19 lying in the same plane this to maintain the basic thickness x. It covers expanding a considerable area in terms of expansion from, so that no canted use of the holding plate fear. The environment of the bracket 19 could therefore be cut away in layers. At the illustrated embodiment remains the entire Position a peripheral preserved.
  • the disposal position is shown in Figure 12.
  • the bracket 19 is angled into a folded-up position. So the dust filter bag can be easily removed from the vacuum cleaner housing pulled out and carried to the disposal site become. Before that, of course, the locking tab 10 brought into the closed position.
  • the closure tab 10 deviates structurally from that of the first described than their closing active plate part now not the Rubber ring seal 11 overlaid, but with Sections of its edge the rubber ring seal 11th sealingly engages. This is particularly clear from Figures 10 and 11.
  • the subordinate Edge sections of the closure flap 10, which is circular here bear the reference number 24. They close at both ends through V-shaped incisions 25. The vertex is enough up to the clear diameter D1 of the rubber ring seal 11, that is to the circular line. Following the V-shaped incisions 25 go from disk-shaped Section of the locking tab 10 and a tongue 26 Bridge 27 out. Both are directed radially and extend itself in the plane of symmetry, embodied by the said Cutting line.
  • the web 27 leads to the hinge zone 12 Locking tab 10, which is in the interior of the U-shaped Retaining bracket 9 is cut free.
  • the bridge 27 diametrically opposite tongue 26 is supported on the opening edge 9 'from the top layer a and prevents - like also the web 27 - that the locking tab 10 is pressed in Position hangs inside the bag 3. Rather, the radially outgoing material extensions cause one resilient against the bottom of the rubber ring seal 11 acting pressing force and the rest a completely perfect seal.
  • the third embodiment is the same Properties and relationships before, but with the structural Difference that here the bracket 19 is not the material of the rest, i.e. area away from the opening the holding plate 1 is cut free, but from the the areas having opening 9.
  • This bracket too has a U-shape and extends concentrically and radially outward spaced from the opening edge 9 'of the opening 9. Beyond this cutout remains Material of the top layer a stand, which also means here Maintain the basic thickness x right into the periphery is.
  • Said gripping niches 28 can be trained of an assignment module can be included by there protrusions on the housing side (not shown).
  • the holding plate 1 has several edges tooth-like, outward projections 30, which in corresponding recesses of the housing come in and also serve to ensure tamper evidence.
  • tooth-like projections 30 prove to be right stable, due to the prevailing three layers.
  • the one bracket extends 19 embodiments having the hinge zone 23 not in the transverse central plane of the holding plate, but slightly offset in the direction of the opening 9. This is the larger material accumulation there of the holding plate 1 compensated.
  • the fourth embodiment differs from the former insofar as the tongue 26 there Component in a reaching to the edge of the holding plate 1 Zone is cut free, i.e. a larger one Gripping length preserved. Nevertheless, the basic thickness remains here x essentially obtained by looking at the material the top layer a continues laterally down to the narrow tooth-like protrusions there 30. There is a forked section.
  • V-shaped incisions 25 set at the transition area to web 27 no longer directly in the band-shaped inlet zone between web 27 and disk-shaped Section of the locking tab 10, but offset. This results in the circumferential direction a slight shortening of the edge portions 24 that are this makes it even easier to "thread” into the opening 9, to come to the grip of the rubber ring seal 11.
  • All of the exemplary embodiments have one thing in common Area of the holding plate 1 arranged, all three layers penetrating hole 31. This extends near the edge and lies in the plane of symmetry of the holding plate 1.
