Patent ID: 8047704

Claim:
A dispenser suitable for mixing and dispensing a two- or more-part curable composition comprising: a) a dispenser body having a fore end and an aft portion; b) a manifold integrated into and supported by the dispenser body, said manifold having (i) an aft region comprising a plurality of manifold inlets defining the point of entry of the components to be mixed into the manifold, said manifold in fluid communication with feed tubes for said components, at least one for each part of the composition to be mixed, (ii) a generally cylindrical fore region ending at a fore end comprising a fore face having a plurality of manifold outlets at its fore end and a seal means associated with its outer circumference at or near its fore end, and (iii) a central region intermediate the aft region and the fore region and defined by a plurality of channels through the manifold, each channel in fluid communication with a manifold inlet and at least one manifold outlet; c) guide and tube forming means associated with or integrated into the dispenser body and positioned about the manifold aft of the seal means, which guide and tube forming means are adapted to (i) wrap an advancing at least one continuous length of a strip of reaction tube stock having two parallel continuous edges lengthwise about the manifold, each edge wrapping around opposite sides of the manifold, (ii) bring the continuous edges of the stock material(s) into contact with one another forward of the feed tubes associated with the aft region of the manifold, thereby completely encasing the circumference of manifold body within the lumen of the tube being formed, and (iii) form a liquid tight seal along the mated edges; d) a dispenser outlet associated with the fore end of the dispenser body; e) a mixer means integrated into and supported by the dispenser body and intermediate said manifold and said dispenser outlet; and f) a reaction tube pathway extending from the guide and tube forming means, past the fore face of the manifold to the dispenser outlet.
