Patent ID: 6837612

Claim:
A mixing device for mixing at least two compounds in a form of at least one dental mold compound and at least one catalyzing compound for communication with at least one dispensing device having dispensing opening for dispensing the at least two compounds, the mixing device comprising: a) a housing, having; i) at least one mixing area disposed within said housing and extending along A longitudinal axis; ii) at least one coupling section having: a) at least two coupling openings, comprising at least a first coupling opening and at least a second coupling opening for coupling with the dispensing openings of the dispensing device, b) at least two duct in communication with said at least one mixing area and comprising at least one first duct and at least one second duct, wherein said at least one first duct has a first segment that extends from said at least one first coupling opening in an axial direction substantially parallel to said longitudinal axis of said mixing area; and a redirecting segment coupled to and in communication with said first segment, and a second segment coupled to and in communication with said redirecting segment, wherein said second segment extends substantially parallel with said longitudinal axis of said at least one mixing area wherein said at least one first duct is formed to extend a flow time of at least one of the at least two compounds in relation to a flow time of at least another of the at least two compounds flowing through said at least one second duct; iii) at learnt two inlet openings comprising at least one first inlet opening and at least one second inlet opening with said at least two inlet openings in fluid communication with said at least one mixing area and said at least one coupling section for allowing the at least two compounds to flow from said at least one tirot duct and said at least one second duct into said at least one mixing area; iv) at least one outlet opening, in fluid communication with said at least one mixing area, for dispensing a mixed compound which is mixed from the at least two compounds in said at least one mixing area; and b) at least cane mixer element disposed in said mixing area of said housing said at least one mixer element being pivotable about said longitudinal axis of said mixing area; wherein the at least two compounds are dispensed from the at least one dispensing device through the dispensing openings into said at least two coupling openings through said at least two ducts and said at least two inlet openings wherein the at least two compounds are mixed in said at least one mixing area by said at least one mixer element and then dispensed through said at least one outlet opening.
