Toilet plunger

A toilet plunger comprising:

• a bottom skirt, skirt having a thickness at an outer circumferential edge less than a thickness of the skirt at an inner-circumferential edge, a lower skirt surface defining a plane which is perpendicular to a longitudinal axis of the plunger;
• a plurality of at least three bellows, a first bellow secured to an upper surface of the skirt, wherein an upper surface of bottom skirt defines a plurality of rectangular ribs, each rib having an axis along its length that is tangential to the outer circumferential edge of the skirt, a second bellow position above and attached to the first bellow, and a third bellow, positioned above and attached to the second bellow, an interior space defined by the plurality of bellows defining a plunger volume;
• a handle securing region positioned on top of the plurality of bellows and having a cylinder defining an inner cylinder surface having a plurality of threads adapted for receiving a handle and an outer cylinder wall;
• a plurality of reinforcing ribs having a vertical wall attached to an outer cylinder wall, each reinforcing rib further defining a bottom wall supported on an upper surface of the bellow top wall, each reinforcing rib further defining an edge wall that extends from a circumferential edge of the bellow top wall to an upper edge of cylinder.
