Abstract

A vacuum cleaner bag includes a bottom part having a substantially rectangular base section. A projecting section is disposed proximate to at least one side of the base section. The projecting section, when folded up for the storage position, rests on the base section. Sidewall sections extend peripherally in a direction away from the bottom part to form an inside space.
