Definitions

  • the invention relates to a dust filter bag for a vacuum cleaner with a holding plate which has a seal-closed opening for a pipe socket of the suction part of a vacuum cleaner, the opening being closable from the outside with a separate closure flap which has an insertion area.
  • Dust filter bags of this type have already become known in various configurations. Attention is drawn to the German utility model 78 32 780 and the German utility model 90 01 528.
  • Such dust filter bags usually have a stiffened upper holding plate, for example made of a thicker cardboard material, while the dust filter bag itself usually consists of a cloth-like cellulose material.
  • the holding plate By means of the holding plate, the dust filter bag can be inserted into the device and connected to the pipe socket mentioned.
  • the opening of the dust filter bag is usually closed with a seal which consists of a circular rubber part which bears against the opening from below. This lies against the opening with a certain preload from the inside.
  • this seal is forcibly opened by the pipe socket.
  • the seal should come into contact with the opening from the inside. In fact, this does not occur with the desired reliability, especially when the dust filter bag is full.
  • the object of the invention is to design and develop a dust filter bag in such a way that the closure flap is more convenient to use, in particular.
  • the focus is first of all on the locking tab being releasably connected to the holding plate in its open position.
  • the closure flap is not freely connected to the holding plate and can interfere with handling, for example, when inserting the dust filter bag into the vacuum cleaner. Rather, the locking tab is firmly connected to the holding plate for handling.
  • the closure flap is adhesively bonded to the holding plate. For example, via a punctiform or circular glue point. This glue point is formed only in such a size that the closure flap willfully easily detached from the holding plate when required can be, in such a way that destruction of the closure flap only occurs to a practically insignificant extent.
  • the locking tab is basically circular in its insertion area.
  • the insertion area is connected to the sealing cover by means of a strip-shaped connecting tab.
  • This strip-shaped connecting tab can be designed with a comparatively small width, so that the insertion area appears to a greater extent in a circular manner. It is important here that the insertion area is first connected to the holding plate at a distance from the opening, for example 2.3 cm. This promotes manipulation of the insertion area.
  • the insertion area is also releasably connected to the holding plate by means of a strip-shaped attachment tab. The detachable connection is implemented in detail in one of the ways already described above.
  • the insertion tab is connected to the closure cover by two additional tabs, the connecting tab and the attachment tab, the attachment tab being detachably connected to the holding plate, however. It is further preferred that the connecting tab and the attaching tab are connected to the insertion area in an axial extension to one another. It is also proposed that the insertion area have a plurality of insertion tabs. These insertion tabs serve to reach under an edge of the opening in order to positively connect the closing tab to the holding plate and thus to close the opening in a durable manner.
  • An insertion tab can preferably be designed in the form of a circular strip.
  • the closure flap can also consist of a reinforced paper material, for example cardboard.
  • a vacuum cleaner bag 1 with an upper holding plate 2 is shown and described, initially with reference to FIG. 1.
  • the upper holding plate 2 has an opening 3, which is closed with a sealing closure 4 which bears against the inside after a first use.
  • the sealing closure 4 is pressed into the vacuum cleaner bag 1 when the vacuum cleaner bag is inserted into a vacuum cleaner through a pipe socket of the vacuum cleaner.
  • a closure flap 5 is formed, with which the opening 3 can be closed from the outside after use of the vacuum cleaner bag 1, in particular when the vacuum cleaner bag 1 is filled to the brim.
  • the closure flap 5 consists of an essentially circular insertion area 6 and a fastening flap 7 as well as a connecting flap 8.
  • the fastening flap 7 is detachably connected to the holding plate 2 via a circular gluing point 9.
  • the gluing point 9 is formed on the fastening tab 7 or at a location of the holding plate 2 assigned to the fastening tab 7.
  • the gluing point 9 is preferably arranged such that an outwardly projecting area 10 of the fastening tab 7 remains, with which the fastening tab 7 and thus the entire locking tab 5 can be detached from the holding plate 2 if necessary.
  • the position of the adhesive point 9 can be seen in particular from FIG. 2.
  • the locking tab 5 is shown in the inserted state in the opening 3. It can be seen that four insertion tabs 14, which are formed on the insertion area 6, each engage under the opening 3 over a depth t.
  • the insertion tabs 14 are designed in the form of a circular strip and are separated via separation slots 15 both from one another and to the connecting tab 8 or the attachment tab 7.
  • the separation slots 15 are formed at an acute angle, pointing radially inwards.
  • the connecting strap 8 is connected to the holding plate 2 at a distance a, at a distance of approximately 1.5 cm in the exemplary embodiment.
  • the holding plate 2 is composed of the actual plate body provided with the reference symbol and the closure flap 5, which latter also reinforces the actual plate body in the region of the opening 3.
