Definitions

  • the present invention relates to a vacuum cleaner bag, and a method for manufacturing a vacuum cleaner bag.
  • the DE 20 2008 016 300 discloses a vacuum cleaner bag in which an inwardly directed fold is arranged on one side. During operation of the vacuum cleaner bag, this fold inflates outwardly, thus increasing the internal volume of the vacuum cleaner bag.
  • a disadvantage of such wrinkles is that they inflate so much and move outward that the filter material presses against the inner wall of the dust chamber of a vacuum cleaner, so that in these areas, a flow through the filter material is difficult or prevented, which deteriorates the suction power. If the wall section folded inwards remains folded in, this likewise impairs the suction power since the filter material is not or only insignificantly flows through in the region of the fold.
  • the vacuum cleaner bag comprises an air-permeable filter material upper part and a lower part between which at least one intermediate part is arranged on one side, which is peripherally connected to the upper part with a first layer and a second layers with the lower part, wherein the first and second Location connected to at least one seam.
  • the intermediate part thus forms a transition between the upper part and the lower part, so that the intermediate part forms part of the outer wall of the vacuum cleaner bag, which increases the effective filter area and avoids the disadvantages with regard to wrinkling. As a result, the service life of the vacuum cleaner bag can be significantly increased.
  • a first chamber and a second chamber are formed in the vacuum cleaner bag, which are at least partially separated from each other via the intermediate part. Due to the formation of chambers, the intermediate part extends from an outer region into an inner region and thus forms a constriction, so that a large filter surface is flowed through. It is also possible to provide a plurality of intermediate parts between the upper part and the lower part, which form an outer wall of the vacuum cleaner bag.
  • the intermediate part is formed substantially frame-shaped. Then, the intermediate part can be flowed through in a central region and forms a transition between two adjacent chambers of the vacuum cleaner bag, while in the outer region a connection to the upper part and / or lower part is made.
  • the first and second layers are connected in plan view within the lower part and / or the upper part, in particular by adhesive or welds.
  • a passage opening is preferably formed, which forms a transition between a first and a second chamber.
  • the vacuum cleaner bag is preferably formed as a flat bag, the edge side is four-ply and formed in a middle region two-ply.
  • the central area is then formed by the area of the passage opening, outside the passage opening is the frame-shaped intermediate part, that in the inner region has a connecting seam between the first and the second layer and at an outer edge a connection to the upper part or the lower part.
  • the connection can be made partially as a connecting seam by gluing or welding, but also an integral connection is possible if the intermediate part is at least partially formed integrally with the upper part and / or the lower part.
  • At least one holder is arranged adjacent to the passage opening, by means of which the first layer and / or the second layer is fixed to the upper part and / or lower part.
  • the holder may be formed by a piece of material which is integrally formed with the first and / or second layer, preferably by punching the through hole, wherein a part of the punched piece of material remains connected to the first or second layer.
  • At least one passage opening is recessed in the intermediate part. Then, a separation of the vacuum cleaner bag in a first chamber and a second chamber is made by the intermediate part, which are connected to each other via the passage opening. In this case, a peripheral connecting seam is produced around the passage opening, so that the vacuum cleaner bag is designed to be closed with the two chambers.
  • the material layers can be folded over to form an upper part and a lower part to the intermediate part and connected at the edge to the intermediate part.
  • the intermediate part is integral with formed the upper part or the lower part, so that in the region of the folding edge no connection seam must be provided.
  • a vacuum cleaner bag 1 comprises an upper part 2 and a lower part 3 of a fabric, in particular a nonwoven fabric, paper, foil or a composite material.
  • the vacuum cleaner bag 1 is divided by an intermediate part 4 into two chambers 15 and 16, which have approximately the same volume.
  • the intermediate part 4 comprises an upper first layer 5 and a lower second layer 6.
  • the upper layer 5 is connected to an edge 7 via a seam 17 with the upper part 2.
  • On the opposite side of the upper layer 5 is connected via a folding edge 20 with the upper part 2, since the upper layer 5 and the upper part 2 are integrally formed of the same material. It is also possible to form the upper layer 5 and the upper part 2 separately, so that instead of the folding edge 20, a further seam is present.
  • the lower second layer 6 is connected to an edge 8 via a seam 9 with the lower part 3.
  • the lower layer 6 is over a folding edge 10 is connected to the lower part 3, wherein the lower part 3 and second layer 6 are integrally made of the same filter material, wherein also here instead of the folding edge 10 with separate formation of the second layer 6 and the lower part 3, a seam can be provided.
  • the upper layer 5 is connected to the upper part 2 via a seam on the edge, while the lower layer 6 is connected to the lower part 3 via an edge seam.
  • the upper layer 5 and the lower layer 6 are unconnected in this area. It is also possible to provide on both sides in each case an edge seam for the connection of the upper part 2, the two layers 5 and 6 and of the lower part 3.
  • a passage opening 13 is recessed, which connects a first chamber 15 and a second chamber 16 of the vacuum cleaner bag 1 together.
  • a circumferential connecting seam 14 is provided, which connects the first layer 5 with the second layer 6.
  • the seam 14, as well as the seams 9 and 17 may be formed as adhesive or welds.
  • the upper part 2 and the lower part 3 consists of a multilayer nonwoven fabric and the seams 9, 14 and 17 are formed by welds.
  • a holding plate 11 is provided on the upper part 2, in which an inflow opening 12 is formed.
  • the inflow opening 12 can be arranged in alignment with the recess 13, but also a laterally offset arrangement of the recess 13 with respect to the inflow opening 12 is possible, so that then the first layer 5, which is arranged opposite the inflow opening 12, forms an impact protection.
  • the passage opening 13 is preferably formed larger than the inflow opening 12th
  • FIG. 2 The items of a vacuum cleaner bag are after FIG. 1 shown before production.
  • the upper part 2 is placed on the edge over the lower part 3, wherein the middle, two-layered area forms the later intermediate part.
  • a passage opening 13 is produced, while in the upper part 2 an inflow opening 12 is punched out.
  • the inflow opening 12 and the passage opening 13 can later be aligned, but also be arranged laterally offset from one another.
  • a connecting seam 14 is now produced, which connects the two-ply region of the upper layer 5 and the lower layer 6 to one another, wherein the connecting seam is arranged circumferentially around the through-opening 13 in the form of a frame.
  • the upper part 2 is folded down until the in FIG. 3 shown position is reached.
  • a folding edge 20 is now formed, which connects the upper part 2 with the upper layer 5.
  • the free edge of the upper part 2 can now be connected to the free edge of the upper layer 5 via a seam 17.
  • the lower part 3 is then folded, as shown in FIG. 4 is shown. Subsequently, the free edge of the lower part 3 is connected to the free edge of the lower layer 6 at the connecting seam 9. On the opposite side of a folding edge 10 is formed.
  • the opposite sides are now cut perpendicular to the folded edges 10 and 20 and connected to each other via seams.
  • the upper part 2 and the lower part 3 can be supplied to a processing station in the form of a web, so that the individual vacuum cleaner bags 1 are cut perpendicular to the conveying direction and finished with weld seams at the edge.
  • all four layers can optionally be connected to one another via a seam, or two spaced seams are provided once between upper part 2 and upper layer 5 and once between lower layer 6 and lower part 3. With two spaced seams, the vacuum cleaner bag can be lighter inflate and better fill a cuboid interior of a vacuum cleaner.
  • a finished vacuum cleaner bag 1 is in plan view in FIG. 5 shown. Perpendicular to the folded edges 10 and 20, cutting edges 19 are formed on opposite sides, which are arranged adjacent to two superimposed seams 18, in particular welds.
  • the vacuum cleaner bag 1 is formed four-layer outside the region of the through hole 13, while in the region of the through hole 13, only a two-layer formation through the upper part 2 and the lower part 3 is present.
