Abstract A new and improved pneumatically shaped ear plug comprising and constructed of an elastomeric hollow body of sheet material dimensioned to and constructed for being inserted into the ear canal or ear cavity, and end of the cylindrical hollow body being of a material performing as a diaphragmatic member so that when it is depressed, the volume of air therein extends the cylindrical side, and vice versa, said end member having a lead or handle means for retracting said diaphragm when it is depressed for restoring it to its original condition, said end member being of such resiliency of said elastomeric material that it retains its depressed condition when it has been so depressed, and retains its released condition when it has been released, thereby constituting a dual state condition as operated upon by action on said diaphragmatic member.

Claim 1
Independent Claim
179 words
A new and improved pneumatically shaped-conforming ear plug and the like comprising an elastomeric hollow cylindrical body for being received within one's ear cavity, said cylindrical body having first and second closed ends and a finite volume of air therein and wherein the first closed end is comprised of a outwardly extending semi-spherically shaped diaphram which includes handle means mounted centrally thereon, said first and second closed ends having elastomeric consistency to perform as diaphragmatic members so that when said first closed end is depressed the second closed end is extended and vice versa, said handle means having a termination in a knob and being available to retract said first closed end when depressed to restore it to an original condition, said hollow cylindrical body possessing a ridge forming portion proximate to the first closed end and about an outer diameter of said cylindrical body for performing as a holding and guiding element for insertion within an ear, and said first closed end being essentially constructed and arranged in essentially hemispheric shape to operate as a two-state condition device.
