摘要： Described is, among other things, a dust bag (1) for a vacuum cleaner. The dust bag comprises a filter bag (2) of an air-permeable material and a front connector plate (3) comprising a hole section. The dust bag further comprises a sleeve (5) of a flexible material. The filter bag is attached to the front connector plate and the sleeve is provided outside the filter bag. The sleeve is arranged to keep the filter bag in a folded position and the sleeve is arranged to allow the filter bag to expand when air is blown through a hole formed in the hole section of the front connector plate. Hereby a compact dust bag can be provided that is small, compact and easy to handle before use and which when placed in a vacuum cleaner and air is blown through the filter bag of the dust bag is able to expand by the sleeve releasing the filter bag by the force exerted by the air blown through the dust bag by the vacuum cleaner. Finally, the sleeve can act as a hygienic grip when removing the dust bag from the vacuum cleaner after use for replacement or emptying of the dust bag. The sleeve thus has multiple functions that combine to obtain a user-friendly dust bag.
