Abstract: A multi-functional kiosk embodying the concepts of the present invention utilizes a polygonal base member and a plurality of frame members. First interlocking means releasably secure the frame members to the polygonal base member, and second interlocking means releasably secure the frame members to each other. A hollow, central cavity is defined by the connection of the frame members to the polygonal base as well as to each other. A refreshment dispenser is capable of being supported within the hollow, central cavity of the kiosk, and a trash receptacle is also capable of being supported within the hollow, central cavity. An aperture penetrates at least one of the frame members to provide access to the refreshment dispenser and the trash receptacle. Panel portions are provided on the exterior of selected frame members to present advertising displays, and a roof member is releasably secured to the connected frame members.

Abstract: A method for manufacturing a clean air duct (150) includes the steps of providing at least two tubular bodies (152, 156) having at least one open end (153, 157), each said open end having an annular ring (168, 168a) which terminates at an inwardly extending lip (166, 166a); closing an injection mold (210) around each annular ring; injecting a polymeric material into the injection mold to form a cuff (160) around the annular rings, thereby connecting the tubular bodies to form an air duct; opening the injection mold and, removing the air duct from the injection mold. Clean air ducts (10) for interconnecting an air filter to a throttle body comprise a blow molded tubular body (12) with at least one open end (14,16), the open end having an annular ring (72) which terminates at an inwardly extending lip (86) and, connecting means (30) molded around and secured to the annular ring, and the lip.

Abstract: The present invention provides a method for manufacturing a tubular body member for use as a clean air duct (10) including the steps of providing a blow mold (50) with at least one embedded knife (54), forming a tubular body (12) with an apex (78) where the embedded knife is located; removing the tubular body from the blow mold, and cutting the tubular body at the apex so as to form an open end (14,16). Another method for manufacturing a clean air duct includes the steps of providing a tubular body (12) having at least one open end, inserting the open end onto a mandrel (90), closing an injection mold (110) around the tubular body and the mandrel, and injecting a polymeric material into the mold, to secure a connecting means (30) to the tubular body so as to form the air duct. The method concludes by opening the injection mold and removing the air duct from the injection mold.
