Definitions

  • the invention relates to a holding plate for a vacuum cleaner filter bag, the holding plate comprising a base plate with a passage opening arranged therein and a sealing element which is arranged at the edge of the passage opening.
  • Such holding plates are known in a variety of forms for arranging a vacuum cleaner filter bag connected therewith in a vacuum cleaner housing.
  • a nozzle of the vacuum cleaner is usually inserted into the passage opening of the base plate in order to direct the suction air flow into the bag.
  • retaining plates usually have to be suitable for different nozzle diameters, many solutions provide an elastic seal (sealing ring), which is intended to compensate for the differences in diameter of the nozzle.
  • the sealing element is usually formed by a sealing lip made of a thermoplastic elastomer, TPE, which is injection-molded onto the edge of the passage opening of the base plate.
  • the object of the invention is therefore to provide a retaining plate with a sealing element which ensures a secure seal during operation.
  • the sealing element comprises at least one extruded film made of a thermoplastic elastomer, TPE. It has been shown that such extruded films are more suitable than known sealing elements, in particular molded TPE sealing lips. The film can also be made significantly thinner than injection-molded sealing lips, because flat and elongated cavities cannot be reliably filled in the injection molding process.
  • the holding plate can be attachable to a holding device in a vacuum cleaner housing.
  • the holding plate can be arranged, in particular fixable, in a predetermined position in the vacuum cleaner housing.
  • the vacuum cleaner filter bag can be pushed over a connection piece on the vacuum cleaner side with the aid of the retaining plate.
  • “Arranged at the edge of the passage opening” means here that the sealing element projects at least partially beyond the edge of the passage opening towards the passage opening and thus at least partially overlaps the passage opening.
  • the sealing element thus forms a sealing lip for the passage opening of the base plate.
  • the sealing element can be arranged in the same plane as the base plate, in particular as the passage opening. In this case, the sealing element can therefore be arranged partially or completely along the circumference of the passage opening.
  • the sealing element can be arranged in a plane which is arranged parallel to the plane of the passage opening.
  • the sealing element can in particular be arranged on the side of the base plate which is used to connect to the bag wall of a vacuum cleaner filter bag.
  • the sealing element also has a passage opening, which can in particular be arranged concentrically to the passage opening in the base plate.
  • the area of the passage opening in the sealing element is smaller than the area of the passage opening in the base plate. This ensures that a nozzle of the vacuum cleaner comes into contact with the sealing element during operation when the latter is inserted into the passage opening of the base plate.
  • the passage opening in the sealing element can also be circular.
  • the inside diameter of the passage opening in the sealing element is smaller than the inside diameter of the passage opening in the base plate.
  • the inside diameter can be replaced by the maximum extent in the plane of the passage opening.
  • the maximum extent of the passage opening in the sealing element is in this case less than the maximum extent of the passage opening in the base plate.
  • the passage opening in the base plate and the passage opening in the sealing element can have the same or a different shape.
  • the sealing element is annular.
  • any other shape is also conceivable as long as a passage opening in the sealing element at least partially overlaps the passage opening in the base plate so that a nozzle of a vacuum cleaner can be inserted into the passage opening in the base plate and the passage opening in the sealing element.
  • the base plate can also have any shape that can correspond in particular to the corresponding holding device in the vacuum cleaner housing.
  • the base plate is generally a flat component, the thickness of the base plate in particular being significantly less than the extent of the base plate in a plane perpendicular to it (length / width).
  • the at least one extruded film can be a blown film or a cast film.
  • the at least one extruded film can have a first side and an opposite, second side, the first side having a greater roughness than the second side.
  • the first side with the greater roughness can be arranged during operation of the holding plate in such a way that it comes into contact with the nozzle of the vacuum cleaner which is inserted into the passage opening.
  • the second side with the lower roughness can point away from the surface of the connecting piece, in particular towards the dust space of a filter bag connected to the holding plate. It can thereby be achieved that the connecting piece can be inserted into the passage opening more easily.
  • a surface of the sealing element that is too smooth could in fact lead to the connection piece sticking to the sealing element, so to speak, and therefore a high static friction has to be overcome in order to insert the connection piece.
  • it is more difficult for suction material to adhere to the smoother second side because of the lower roughness, so that an undesirable filter cake does not form or does not form so strongly in the area of the passage opening.
  • the melt flow index of the thermoplastic elastomer of the at least one extruded film is less than 10 g / 10 min, in particular less than 5 g / 10 min, in particular less than 3 g / 10 min. This means that the melt flow index is significantly lower than that of plastics that are used in the injection molding process. Injection molding processes require plastics with a melt flow index of more than 40 g / 10 min.
  • the thickness of the at least one extruded film can be less than 0.35 mm, in particular less than 0.25 mm, in particular less than 0.15 mm.
  • the thickness of the film can in particular be constant.
  • Such thin structures can be injection molded cannot be produced because the flat and elongated cavities required for this could not be filled. In the injection molding process, therefore, only structures, in particular sealing elements, with a thickness of more than 0.4 mm can be produced.
  • the at least one extruded film can be connected, in particular welded, to the base plate.
  • the at least one extruded film can be connected to the base plate, in particular (ultrasound) welded, either directly or via a connecting layer, which in particular comprises a nonwoven fabric.
  • a connecting layer can be used, for example, when the plastic material of the base plate is incompatible with the plastic material of the sealing element. In the latter case, the plastic material of the base plate would essentially not mix with the plastic material of the sealing element, so that these plastics would not be directly weldable to one another.
  • the sealing element can also comprise several layers of extruded films made of a thermoplastic elastomer, TPE (in particular produced by coextrusion).
  • TPE thermoplastic elastomer
  • a multilayer sealing element can thus be provided in this way. It is also possible to combine one or more layers of extruded films made of a thermoplastic elastomer, TPE, with one or more layers of nonwoven to form a sealing element.
  • a passage opening can then be arranged in each of the layers, the passage openings being arranged coaxially and thus forming the passage opening of the sealing element.
  • the diameter of the passage openings in the individual layers can be designed to be the same or different.
  • At least two of the layers of extruded films can consist of different plastics.
  • the one or more further layers can be optimized for elasticity and thus sufficient sealing effect, for example.
  • the multiple layers of extruded films can be connected to one another, in particular welded or glued.
  • the multiple layers can in particular be connected to one another in an area in which the sealing element is not also connected to the base plate.
  • the layers of the sealing element can already be connected to one another before they are connected to the base plate, which simplifies production, since there are not several layers of the sealing element, each with a passage opening, to each other and to the base plate and its passage opening must be positioned.
  • the diameter of the passage openings in the individual layers can be made the same or different.
  • the nonwoven layer can be arranged towards the nozzle.
  • the rough surface of the nonwoven fabric then has a similar effect as the roughening of one side of the film, as described above.
  • the diameter of the passage openings can also be different. This means that even better adaptation to different nozzle diameters can be achieved. So it can be helpful if the film with the smaller diameter of the passage opening has a high elasticity and possibly a small thickness while the film with the larger diameter of the passage opening has a lower elasticity and a greater thickness, in order to thus additionally have a centering function of the connecting piece to take over the passage opening.
  • the base plate can comprise or consist of a thermoplastic plastic.
  • the thermoplastic plastic can in particular be a recycled plastic, for example recycled polyethylene terephthalate, rPET.
  • the rPET can come from beverage bottles (bottle flake chips) or metallized PET films, for example.
  • recycled polybutylene terephthalate (rPBT), recycled polylactic acid (rPLA), recycled polyglycolide and / or recycled polycaprolactone can also be used.
  • recycled polyolefins in particular recycled polypropylene (rPP), recycled polyethylene and / or recycled polystyrene (rPS); Recycled polyvinyl chloride (rPVC), recycled polyamides as well as mixtures and combinations thereof are possible.
  • the base plate can be a stamped part, deep-drawn part or an injection-molded part.
  • the base plate can have been produced by stamping, deep drawing (thermoforming) or injection molding.
  • the invention also provides a vacuum cleaner filter bag comprising a bag wall and an above-described retaining plate connected thereto.
  • the holding plate can thus have one or more of the features mentioned above.
  • the bag wall of the vacuum cleaner filter bag can comprise one or more layers of filter material, in particular one or more layers of nonwoven fabric.
  • Vacuum cleaner filter bags with such a bag wall made of several filter material layers are for example from the EP 2 011 556 or the EP 0 960 645 known.
  • a wide variety of plastics can be used as the material for the nonwoven layers, for example polypropylene and / or polyester.
  • the layer of the bag wall to be connected to the holding plate can be a nonwoven layer.
  • the bag wall of the vacuum cleaner filter bag can also comprise or consist of recycled plastic.

  • the bag wall can be connected, in particular welded, to the base plate via the sealing element. As a result, the bag wall and the sealing element can be connected together with the holding plate, in particular the base plate, which simplifies production.
  • nonwoven is used according to the definition according to ISO standard ISO9092: 1988 or CEM standard EN29092.
  • the terms nonwoven or nonwoven and nonwoven in the field of the production of nonwovens are delimited from one another as follows and are also to be understood in this way in the context of the present invention.
  • Fibers and / or filaments are used to produce a nonwoven fabric.
  • the loose or loose and still unbound fibers and / or filaments are referred to as fleece or fiber fleece (web).
  • fleece binding step By means of a so-called fleece binding step, a nonwoven fabric of this type is finally produced which has sufficient strength to be wound up, for example, into rolls. In other words, a nonwoven fabric is made self-supporting through the consolidation.
  • the bag wall can have a through opening, in particular wherein the through opening of the bag wall is arranged in alignment with the through opening of the base plate.
  • the through-opening in the base plate and the through-opening in the bag wall can form an inflow opening through which the air to be cleaned can flow into the interior of the vacuum cleaner filter bag.

  • the holding plate produced in this way can have one or more of the features mentioned above.
  • FIG. 1 shows the schematic structure of an exemplary vacuum cleaner filter bag.

  • a sealing element 4 arranged on the edge of the passage opening 3 is also shown.
  • the sealing element 4 is intended to prevent or limit the escape of dust from the vacuum cleaner filter bag by sealing the area between the edge of the passage opening 3 and the outside of a connection piece of the vacuum cleaner.
  • the sealing element 4 comprises a passage opening which overlaps the passage opening 3 of the base plate. Since the area of the passage opening in the sealing element 4 is smaller than the area of the passage opening 3 of the base plate, an annular sealing lip is formed which protrudes over the edge of the passage opening 3 of the base plate inwards, i.e. towards the center of the passage opening 3.
