Abstract
A flexible collapsible corrugated sewer hose has a collapsible and expandable corrugated section providing durability, a tight bend radius and a relatively small collapse ratio. An expansion of the corrugations permits convenient manipulation and installation of the sewer hose having a self supporting structure and crush resistance without helical reinforcement.

A flexible collapsible corrugated sewer hose comprising a first end section, an intermediate section having a wall formed of annular corrugations, and a second end section, in which the corrugations comprise smaller rings having tuck walls connected at tuck angles extending to larger rings so that tuck walls are hingedly connected at larger rings to static walls extending at static angles and the static walls connect larger rings to adjacent smaller rings, where the ratio of static angles to the tuck angles is less than 1.15 to 1.0 wherein an interior of the hose is extruded of a first material and an exterior of the hose is extruded of a second material.
A flexible collapsible corrugated sewer hose comprising a front end section, an intermediate section of annular corrugations and a second end section wherein the annular corrugations comprise smaller rings and larger rings connected by hose walls and where each end section has a segment of right hand helix threads and a segment of left hand helix threads.
A flexible collapsible corrugated sewer hose comprising a first end section, an intermediate section having a wall formed of annular corrugations, and a second end section, in which the corrugations comprise smaller rings having tuck walls connected at tuck angles extending to larger rings so that tuck walls are hingedly connected at larger rings to static walls extending at static angles and the static walls connect larger rings to adjacent smaller rings wherein the sum of the tuck angle and the static angle defines the angular orientation between the tuck wall and the static wall and said angular orientation is in the range between 80° and 110°.
