Plunger appliance for toilets

A portable plunger for a toilet having a bowl outlet passage that might become clogged, comprising

• an elongated shaft having a hand gripping portion adjacent one end thereof;
• a plunger head fixed to the shaft adjacent the end thereof opposite the hand gripping portion;
• said plunger head having an impervious flexible material defining an exterior surface sized slightly larger than the toilet bowl outlet passage;
• and
• said plunger head also being resilient and elastic operable to allow reduction of the exterior head surface to a size smaller than the bowl passage to allow plunger head insertion into the passage and operable further to cause expansion of the exterior surface at least as an annular region sealingly against the walls of the bowl passage operable to block the passage in the mode of a piston positioned therein;
• whereby
• axial shifting of the shaft concurrently shifts the plunger head axially in the bowl passage, the plunger head hydraulically acting on water/waste in the bowl passage to create pressure and/or flow surges therein that serve to break up clogs in the passage.
