ABSTRACT:
A pair of concentric cylindrical members are arranged for relative sliding movement with the lower end of the inner member being formed with outwardly projecting flexible blades. The blades are adapted to displace rubber guard elements covering a sink opening when the pair of members are received in a disposal unit, or in a sink opening without a disposal unit. The flexible blades are normally held against their outward projection when contained within the outer member, but upon sliding movement of the inner member axially relative to the outer member, will flex radially outward so as to maximumly displace the rubber guards. The resulting displacement establishes an improved unobstructed central passageway in communication with the disposal unit grinding hopper, whereby undesired foreign matter therein may be withdrawn with the use of elongated, slenderized tongs. Optionally, lights may be supported on preferably lower portions of the cylindrical members for improved grinding hopper illumination; however, such lights can be emitted due to the maximized degree of rubber guard displacement.
