Cell culture dish

The cell culture vessel comprises a plastic vessel (2) with a base wall (4) and a side wall (5) rotating on the base wall, a plastic cover (3) that rests in a sealing position sealing on the side wall, means (7) for detachable holding the cover at the vessel over the sealing position in an aeration position in which an aeration gap is provided between the side wall and the cover, and means for sealing on cover and vessel. The holding means are surmountable through the compression of the cover and the vessel in order to bring the cover from the aeration position into the sealing position.

The holding means are surmountable through the compression of the cover and the vessel in order to bring the cover from the aeration position into the sealing position. The holding means comprises a supporting element between the cover and the vessel on the vessel in the aeration position. The side wall of the vessel has a laterally protruding supporting element and the cover has a cover side wall projecting towards bottom by a cover wall, where the cover side wall is mountable on the supporting element. The supporting element projects from the external side of the side wall and the cover side wall overlaps the side wall of the vessel. The vessel has three flexible supporting elements on opposite sections of the side wall. The first pair of the supporting element has two opposite sections of the side wall and a second pair of supporting elements has opposite sections of side walls. The second pair is arranged against the first pair around 90[deg] . The flexible supporting elements have an elastic tongue. The elastic tongue is connected at an end tightly with the side wall, extends itself parallel to the base wall, has a recess equipped at another end to the cover and is mountable on the cover side wall. The culture vessel has a handle edge projecting external of the side wall. The supporting element is a section of handle edge. The sealing means has an undercut revolving at the external side of the side wall and a sealing area protruding at the internal s
