The housing includes an upper housing section and a lever moveable relative to the upper housing section between a coupled position and an uncoupled position. The flexible seal is between the upper housing section and the mixing vessel. The lever couples the mixing vessel to the upper housing section when in the coupled position and uncouples the mixing vessel from the upper housing section when in the uncoupled position. When the lever is in the coupled position, the mixing vessel is sealed against the upper housing section by the flexible seal. ## Claims ### Claim 1 A frozen drink maker comprising: a housing comprising an upper housing section and a lever moveable relative to the upper housing section between a coupling position and an uncoupling position;
