Patent number: 6945688Abstract: A container assembly for mixing materials having a base defining a mixing chamber for mixing the materials and a cover mounted to the base covering the mixing chamber. A sealing portion depends from the cover and engages an inner wall of the base. The sealing portion is flexible and angled outwardly such that during the engagement of the sealing portion with the inner wall, the sealing portion flexes and conforms to the inner wall to seal the mixing chamber. In addition, a first locking device is disposed on the base and a second locking device is disposed on the cover. A lifting mechanism is disposed on one of the base and cover for automatically lifting the cover relative to the base as the cover is being removed from the base for preventing a discharge of material from the mixing chamber.Type: GrantFiled: January 10, 2002Date of Patent: September 20, 2005Assignee: Stryker InstrumentsInventors: Richard F.
