<p>A flexible convoluted hose construction is provided herein. The flexible convoluted hose comprises an elongated, single-piece, elastomeric strip having a base and first and second connecting members extending in the same direction from the base, with the first connecting member extending from a central part of the base to define a lateral extension of the base outwardly of the first connecting member. The second connecting member extends from an end portion of the base. The strip is disposed in a helical pattern, with the first and second connecting members connected to define the hose construction having a plurality of helical turns defining alternating crests and troughs. The lateral extension in each helical turn of the strip slidingly engages the base beneath the second connecting means in underlapping relation to provide the hose construction with a substantially smooth inside surface, the smooth inside surface being provided even with the hose construction extending in a curved path due to the lateral extension slidably engaging the base portion and bridging any gap which would otherwise be produced in the inside surface along an outer radius of the curved path. The hose thus is substantially free of gaps or irregularities capable of trapping materials flowing through the hose construction.</p> |
