Embodiment Construction

[0056] figure 1 A cross-sectional view of an embodiment of the closing device according to the invention is schematically shown. In this figure, with figure 2 The closing device is in the first position and has a smaller extension in a direction perpendicular to the inlet plane than in the second position shown in .

[0057] Inside the vacuum cleaner filter bag 1 a closing device 2 is arranged in the region of the (circular) inlet 3 . The retaining plate 4 is arranged on the outside on the vacuum cleaner filter bag.

[0058] In the illustrated embodiment, the closing device 2 in the second position is in the shape of a cuboid. The base region 5 of the cuboid is arranged parallel to the plane of the inlet 3 . The base region is the closing surface for the inlet.

[0059] The first sealing element 8 is arranged inside the closing device. The sealing element is arranged around the entire inlet. This sealing element achieves a suitable seal in particular after introduction...

Abstract

The vacuum cleaner filter bag (1) comprising an inlet opening (3), a retaining plate (4), which is situated on the exterior of the bag in the vicinity of the inlet opening and can be attached to a retaining device on a vacuum cleaner in order to fix the vacuum cleaner filter bag. The inlet opening is sealed in the first position of the sealing device (2) and is open in the second position of the latter. A sealing device situated in the vicinity of the inlet opening, which is configured in such a way that it adopts a first position when the retaining plate is not attached to the retaining device and a second position by the attachment of the retaining plate to the retaining device.

Description

technical field [0001] The present invention relates to a vacuum cleaner filter bag with an improved closure. Background technique [0002] A closure element is provided in the vacuum cleaner filter bag, in particular when handling a full filter bag, for closing the filter bag so that the dust contained in the filter bag cannot escape. [0003] The prior art discloses various variations for closing vacuum cleaner filter bags. [0004] EP0499168 describes a retaining plate and a closing plate constructed as a one-piece molded part. The opening in the retaining plate is closed by displacing a closing plate connected to the retaining plate via slats. [0005] DE20315574 discloses a connection comprising a displaceably guided closing plate. The closing plate must be pulled to the closed position by hand. [0006] Another retaining plate with a separate closing element is known from WO 98 / 389000. [0007] Said vacuum cleaner filter bags have the disadvantage that the closing...
