Method for indicating shelf-life after mixing pre-dosed, pre-packaged two-part dental compositions

Image Number 4 for United States Patent #7569185.

A pre-dosed, pre-packaged mixing system and associated method for mixing, storing, and dispensing a two-part dental composition that becomes less stable upon mixing. The mixing system includes a pre-dosed, pre-packaged quantity of a first component contained within a first chamber, and a pre-dosed, pre-packaged quantity of a second component contained within a second chamber. The chambers are separated by separation means so as to separate the two-components prior to mixing. Once mixed, the practitioner is able to record a mixing and/or expiration date on at least a portion of the mixing system so as to indicate a shelf-life of the less stable mixed dental composition.
