Patent ID: 7610635

Claim:
A drain cleaner for use with a drain assembly including a drain pipe having a U-joint and a flange coupled to the drain pipe and defining a drain inlet, the drain cleaner comprising: a stopper head having a seal sized to engage the drain inlet and an inlet passage extending from an inlet port formed in a top surface of the stopper head to an outlet port formed in a bottom surface of the stopper head; a cap removably coupled to the inlet port; a conduit coupled to the stopper head with a proximal end in fluid communication with the stopper inlet passage and a distal end, an internal passage extending between the conduit proximal end and conduit distal end, the conduit distal end being sufficiently spaced from the conduit proximal end so that the conduit distal end is disposed in the drain pipe when the stopper head is adjacent the drain inlet, the conduit being formed of a material that is sufficiently flexible to navigate a drain pipe path; and a drain cleaning composition supported below the stopper head bottom surface and positioned such that the conduit defines a partition between the conduit internal passage and the drain cleaning composition.
