Abstract
The present invention relates to articles comprising a plurality of molded hollow parts (11) having different central axis (14, 15) through the hollow elements, further having passages in walls of the hollow parts transverse to the central axis of the hollow parts. The present invention also relates to methods applying two part curable materials to substrates using the molded parts of the invention as mixing elements.
Claims18
An article comprising:
- two parts wherein each part has two or more sections connected together wherein each section is formed from one or more a molded materials wherein the molded materials form the periphery of a hollow structure having a proximal end, a distal end, a cross section and open passages in the molded material on the periphery of the hollow structure, a central axis through the hollow structure transverse to the cross section of the molded material and the passages in the molded material having a central axis through the passages;
- wherein adjacent sections are connected near the proximal end of each section and the angle formed by the central axis of adjacent connected sections is from about 45 to about 90 degrees and the angle formed by the central axis of the hollow structure of each section and the central axis of the passages in the molded material is from about 45 to about 90 degrees;
- wherein each part is a mirror image of the other and the two parts can be assembled to form a symmetrical structure and one part has connected to one end a molded structure comprising one or more helical shaped elements.
