Definitions

  • the invention relates to a dust filter bag for a vacuum cleaner with a holding plate which has an opening for an intake pipe of a vacuum cleaner, the opening being closable from the outside with a closure tab having an insertion area, which is connected to the holding plate via a strip-shaped connecting tab.
  • Such a dust filter bag is known, for example, from the registered documents of DE-U-90 01 528. As for the state of the art, reference should also be made to the German utility model DE-U-78 32 780.
  • 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 invention presents the technical problem of developing the known dust filter bag in relation to handling the closure flap in a more economical manner.
  • the opening in the holding plate can be closed very effectively by the locking tab. Due to the fact that the closure flap is designed with a smaller width than the insertion area, the possibility arises over a relatively large circular circumference of the insertion area to effectively close the opening. This is supported through the formation of circular tabs.
  • closure tab is releasably connected to the holding plate in its open position. It is thus provided that 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. It is preferably provided here that the closure flap is adhesively bonded to the holding plate. For example, via a punctiform or circular adhesive 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 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 only 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 one of the ways already described above. In such an embodiment, the insertion tab is connected to the closure cover via two additional tabs, the connecting tab and the attachment tab, but the attachment tab is detachably connected to the holding plate.
  • the connecting tab and the attaching tab are connected to the insertion area in an axial extension to one another.
  • the insertion tabs serve to reach under an edge of the opening in order to connect the locking tab to the holding plate in a form-fitting manner and thus to close the opening in a durable manner.
  • the insertion area initially covers one necessary covering from the opening and then forms radially inward separation slots, starting from the outer edge, through which the insertion tabs are formed.
  • the separation slots here preferably have a depth which corresponds approximately to the overlap with the opening. It is further preferred that a total of four insertion tabs are formed.
  • the separation slots separate the insertion tabs from each other as well as to the connection tab or the attachment tab.
  • 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 tab 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 number and the closure flap 5, which latter also reinforces the actual plate body in the region of the opening 3.
