Abstract
Description
- 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 connected 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, two opposite flaps of comparativeley stiff material being arranged between the membranes so that they at least partly cover the openings of the membrane.
- 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.
- It has however proved that dust despite the existence of the flaps disappear from the outlet opening when the container has been removedd which depends on that the flaps move with respect to each other therby forming a slot through which dust can blow out.
- The purpose of this invention is to achieve a sealing arrangement for the inlet opening which gives a far better sealing than previously known arrangemants thereby making the handling of the filled dust container more hygienic than before. This is achieved by means of a device having the caracteristics mentioned in the claims.
- An embodiment of the invention will now be described with reference to the accompanying drawing on which 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 whereas 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.
- As appears from the figures the
dust container 10 comprises a bag 11 of air pervious material such as filterpaper whose opening is covered by aplate 12 of comparatively stiff material for instance cardboard or plastic. Theplate 12 comprises an upper and alower layer layers inlet openings flexible membranes circular opening 14a, 15a the first membrane being fastened and clamped between the twolayers inlet openings 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. - From the
lower layer 12b facing the inner side of the bag two opposite tongues being shaped asflaps membranes first flap 16a has a U-shaped recess whereas the outer end of thesecond 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 themembrane openings 14a, 15a. - The
first flange 16a further has athird membrane 17 which is placed on the side facing the bag 11 this membrane preferably comprising the part which is stamped out from themembrane membrane openings 14a, 15a. The third membrane which is preferably glued on thefirst flap 16a will thus overbridge the open part of the end of the first flap and serve as a support for the end of thesecond 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. During this movement the sleeve will also move the twoflaps - When the cover is opened in order to take out the
dust container 10 the sleeve will be withdrawn from theinlet openings membranes openings 14a, 15a. Thus the twoflaps second membrane 15. When the part of the sleeve which in Fig. 6 is placed at the top is free from theflap 16a the flap will together with themembrane 17 fall back to their original positions, that is in the same plane as theplate 12, whereas theflap 16b is still in touch with the lower part of the sleeve and thus is directed inwardly towards the dust bag. When thesleeve 18 then is completely withdrawn from the dust container theflap 16b will follow and by means of themembrane 15 be pressed towards the lower side of themembrane 17. This means that thethird membrane 17 will serve as a sealing preventing the twoflaps - It should be mentioned that it of course is possible to vary the geometry of the two flaps and the membrane in a suitable way so that the desired function is achieved.
Claims (7)
- Dust container comprising a bag (11) of air pervious material the opening of the bag being covered by a plate (12) of comparatively stiff material, the plate having an inlet opening (13a,13b) which is connected to an air inlet sleeve of the vacuum cleaner, the inlet opening being provided with a first and a second elastic membrane (14 and 15 resp.)each having an opening (14a, 15a) for taking up the inlet sleeve, two opposite flaps of comparativeley stiff material being arranged between the membranes (14,15) so that they at least partly cover the openings (14a, 15a) of the membrane, characterized in that one side of the first flap (16a) is provided with a third elastic membrane (17) which, when the container is not used, at least partly overlaps or is overlapped by the second flap (16b).
