Device for Cleaning a Hollow Vessel

The invention relates to a device for cleaning a hollow vessel ( 6 ) that has a narrow neck at the top and below it a radially widened cavity, having a handle ( 1 ) and a cleaning head ( 2 ) that can be passed through the narrow neck of the hollow vessel ( 6 ), which head is provided with cleaning material and can be spread open in the interior of the cavity. In order for the cleaning head to be able to be better adapted to the contours of the hollow vessel in the case of such a device, and in order to achieve an improved cleaning effect, the invention proposes that the cleaning head ( 2 ) consists of an extensively rigid loop ( 3 ) of elastic material that extends in the insertion direction, which loop is covered with cleaning material and bends outward when it hits the bottom of the hollow vessel ( 6 ), and rests against the bottom and the walls of the hollow vessel ( 6 ) when doing so, adapting to their contour.
