Disposable static mixing device with a reusable housing

A static mixing device for mixing at least two flowable components of a composition from a separate storage container, comprising:

• a disposable mixing conduit having at least two facing sheets of material, at least one of the facing sheets being flexible, the sheets being sealed together at seams such that the conduit defines a peripheral edge, a conduit inlet at an inlet end of the conduit, a conduit outlet at an outlet end of the conduit, and an internal mixing portion communicating with the conduit inlet and the conduit outlet, the mixing portion forming a mixing means operable to mix the flowable components when said components are moved along a flowpath from the conduit inlet to the conduit outlet due to at least one obstruction formed by the sheets and seams, along the flowpath between opposing portions of two of the facing sheets;
• a rigid, reusable housing for supporting the mixing conduit;
• and,
• reusable coupling means supported by the housing, the coupling means being structured to provide a sealed connection between the storage container and the conduit inlet, whereby a flow of the at least two components entering the conduit inlet from the container is combined upstream of the at least one obstruction along the flowpath, divides at the at least one obstruction and recombines downstream of the at least one obstruction, said at least two components becoming mixed along the flowpath;
• wherein the storage container has a storage container outlet and the coupling means includes a substantially annular attachment member comprising an inner radial surface defining structure for connecting to the storage container outlet, a peripheral radial surface and a collar positioned circumferentially around the peripheral radial surface, the inlet end of the mixing conduit being captured between the peripheral radial surface and an interior surface of the collar.
