Abstract:
A vented toilet plunger, comprising:a) a cup; and b) a handle; wherein said cup is resiliently collapsible; wherein said cup is vented; wherein said handle extends axially from said cup; wherein said cup has a vent throughbore through a high point thereof; wherein said cup has a vent valve assembly; wherein said vent valve assembly of said cup extends through said vent throughbore therein; wherein said vent valve assembly is a check valve; wherein said check valve contains a ball; wherein said ball of said check valve normally allows communication through said check valve; wherein said ball of said check valve has weight; and wherein said weight of said ball is not overcome by air, but is overcome by water, so as to allow communication through said check valve when said cup is first put into the water so as to allow the air trapped in said cup to be vented out, but once the air is vented out, the water fills said cup and moves said ball of said check valve to block communication through said check valve so as not to allow the water to pass therethrough.
