Abstract

A storage container (1) for a suspension used for medical purposes, in particular for ultrasonically assisted treatment of periodontitis, dental cleaning or dental preparation, comprises a flexible pouch (2), the interior of which is accessible via a charging and discharging nozzle (5). Situated in the interior of the pouch (2) is a distance element (6), in which a groove system (8, 9, 10) is incorporated. The groove system communicates with the interior of the charging and discharging nozzle (5). When the pouch (2) of said storage container (1) is pressed flat during removal of the suspension it contains, the opposing sides (3, 4) of the pouch (3) are applied during the final phase of emptying against the distance element (6). The groove system (8, 9, 10) contained in the latter however remains clear and forms a path, via which even the last residues of the suspension may be reliably removed from the pouch (2).
