Abstract
A blow molded product which is generally tubular having a first and second open ends, a bellows section intermediate said first and second ends so that the product is flexible, and a skirt adjacent the second end, the skirt having an outer cylindrical outer surface and a lobed inner surface. The bellows section is formed in a blow molding operation and the skirt is formed by injection molding. The final product is formed by thermally fusing the two portions together. This process enables molding of a product with an external surface which may substantially cylindrical with an internal surface which has lobes, or other internal projections or non-cylindrical surface.
