Patent ID: 8042991

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 and having (i) an aft end having a plurality of manifold inlets defining the point of entry of the components to be mixed into the manifold, at least one for each part of the composition to be mixed, (ii) a generally cylindrical fore region ending at a fore end, which fore end comprises a fore face having a plurality of manifold outlets, (iii) a central region defined by a plurality of channels through the manifold, each channel in fluid communication with a manifold inlet and at least one manifold outlet and (iv) a recess adapted to hold a portion of a reaction tubing such that at least a portion of the manifold is within the lumen of the reaction tubing when in place, said recess being either (I) an annular recess in the fore end of the manifold adapted to receive and sealingly engage a butt end of a reaction tube said annular recess comprising either (A) an annular recess having two side walls in the fore face of the manifold wherein the width of the recess, as defined by the distance from one side wall to the other, being such as to create an interference fit between the wall of a reaction tube and the side walls of the annular recess or (B) an indent in the outer circumferential wall of the fore end of the manifold whereby the whole of the fore face of the manifold is circumscribed by the indent such that a reaction tube, when placed therein is secured in place by an interference or press fit between the outer circumference of the manifold at the indent and the inner wall of the barrel of the dispenser body or (II) a circumferential recess about the central region of the manifold and the dispenser further comprises a circumferential seal means extending from the outer surface of the manifold intermediate the circumferential recess and the fore end of the manifold; c) a dispenser outlet associated with the fore end of the dispenser body; d) a mixer means integrated into and supported by the dispenser body and intermediate said manifold and said dispenser outlet; and e) a reaction tube pathway extending from the recess to the dispenser outlet and defining a flow path from the outlets in the fore face of the manifold to the dispenser outlet.
