Definitions

  • This invention relates to a dust container comprising a bag of air pervious material, the opening of the container being covered by a plate of comparatively stiff material the plate having an inlet opening which is connectable to an air inlet sleeve of a vacuum cleaner, the inlet opening being provided with a first and a second elastic membrane each having an opening for taking up the inlet sleeve, first and second opposite flaps of comparatively stiff material being arranged between the membranes so that they at least partly cover the openings of the membranes.
  • Dust containers of the type mentioned above are previously known, see for instance US 5039324.
  • the purpose of the flaps is that they shall close the openings of the membranes when the sleeve is pulled out from the container and hence prevent dust from leaving the container when it is removed from the vacuum cleaner and during further handling.
  • the flaps become closed because the membrane facing the bag by its elacticity moves the flaps back to their original positions in which they are in the same plane as the plate.
  • the purpose of this invention is to achieve a sealing arrangement for the inlet opening which gives a far better sealing than previously known arrangements thereby making the handling of the filled dust container more hygienic than before. This is achieved by means of a device having the characteristics specified in independent claim 1.
  • FIG. 1 in a perspective view shows the entire vacuum cleaner
  • Fig. 2 is an elevation view of the plate belonging to the dust container before it is used
  • Fig. 3 is a view from the middle part of the rear side of the plate before the dust container is used
  • Fig. 4 is a partly exploded perspective view showing the central part of the plate before it has been used
  • Fig. 5 shows the same view when the dust container has been used
  • Fig. 6 is a section on the central part of the plate when the vacuum cleaner has been used i.a. when the sleeve belonging to the cover of the vacuum cleaner is swung out from the dust container.
  • the dust container 10 comprises a bag 11 of air pervious material such as filterpaper whose opening is covered by a plate 12 of comparatively stiff material for instance cardboard or plastic.
  • the plate 12 comprises an upper and a lower layer 12a and 12b which are fixed to each other preferably by glueing.
  • the two layers 12a and 12b each have an inlet oening 13a and 13b which are coaxial with each other.
  • the inlet openings 13a, 13b are partly covered by two flexible membranes 14, 15 each having a central circular opening 14a, 15a the first membrane being fastened and clamped between the two layers 12a and 12b at an area around the inlet openings 13a, 13b.
  • the second membrane 15 is fixed at the lower side of the plate so that the central membrane openings 14a, 15a are aligned thereby allowing an inlet sleeve belonging to the vacuum cleaner to be inserted into and sealed from the openings.
  • first flap 16a has a U-shaped recess whereas the outer end of the second flap 16b is shaped as a complementary U-shaped part so that the ends of the two flaps together form a mainly circular area which is somewhat larger than the membrane openings 14a, 15a.
  • the first flange 16a further has a third membrane 17 which is placed on the side facing the bag 11 this membrane preferably comprising the part which is stamped out from the membrane 14 or 15 to create the membrane openings 14a, 15a.
  • the third membrane which is preferably glued on the first flap 16a will thus overbridge the open part of the end of the first flap and serve as a support for the end of the second flap 16b before the dust container is inserted into the vacuum cleaner.
  • the device operates in the following manner.
  • the dust container is in the usual way inserted into a space used for this purpose in a vacuum cleaner after which the associated cover, which is pivotally arranged in the vacuum cleaner and which is provided with an inlet sleeve 18 extending into the space, is closed.
  • This means that the sleeve is inserted through the membrane opening 14a, 15a so that the membrane will surround the sleeve and seal against it.
  • the sleeve will also move the two flaps 16a and 16b and the third membrane from a position where they are mainly placed in the same plane, that is the position shown in Fig. 4, to withdrawn positions on each side of the sleeve.
  • the flap 16b When the sleeve 18 then is completely withdrawn from the dust container the flap 16b will follow and by means of the membrane 15 be pressed towards the lower side of the membrane 17. This means that the third membrane 17 will serve as a sealing preventing the two flaps 16a, 16b from separating when the bag is exposed for an inner overpressure during handling. In other words an almost complete closure of the bag is achieved which makes the handling of the container more hygienic than before.
