Dish scrubber with changeable scrub head
A dish scrubbing brush includes an elongated handle and a brush head adapted to be releasably attached to the top of the handle. A hollow reservoir located within the handle contains liquid soap. An orifice at the top of the handle communicates with the brush head when it is attached and a pump accessible from the exterior of the handle forces soap from the reservoir to the brush head. The brush head includes a foam brush and an adapter for securing the brush head to the top of the handle. The adapter includes an internal thread that cooperates with a partial external thread on the handle top and includes a rib that cooperates with a slot in the handle top. As the adapter is rotated to be attached to the handle, the brush is drawn toward the handle but does not rotate relative thereto.
1. A dish scrubbing brush with a changeable head comprising: an elongated handle portion having a top end and a bottom end and a brush head adapted to be releasably attached to said top end of said handle portion;
said handle portion including a hollow reservoir therein adapted to contain a quantity of a liquid soap, said handle portion further having an orifice at the top thereof providing a passageway from said reservoir to said brush head when said brush head is attached to said handle portion and further including means accessible from the exterior of said handle portion for forcing liquid soap from said reservoir through said passageway;
said brush head including a brush for scrubbing dishes and the like and an adapter for securing said brush head to said top end of said handle portion, said adapter being so constructed and arranged such that said adapter can be threaded onto said top end and as said adapter is rotated for attaching said brush head to said handle, said brush is drawn toward said handle but does not rotate relative thereto;
wherein said top end of said handle portion includes a partial external thread and a substantially elongated linear slot and wherein said adapter includes an elongated rib adapted to ride in said slot to prevent rotation of said brush as a portion of said adapter is rotated.
2. The dish scrubbing brush with a changeable head as claimed in claim 1 wherein said handle portion includes a removable cap at said bottom end for refilling said reservoir.
3. The dish scrubbing brush with a changeable head as claimed in claim 1 wherein said adapter includes an external cylindrical ring having an interior thread adapted to cooperate with said external thread of said top of said handle portion, said cylindrical ring being freely rotatable relative to the remaining parts of said adapter.
4. The dish scrubbing brush with a changeable head as claimed in claim 3 wherein said cylindrical ring is incapable of linear movement relative to the remaining parts of said adapter.
5. The dish scrubbing brush with a changeable head as claimed in claim 1 wherein said adapter includes an orifice therein in communication with said orifice in said top of said handle to allow liquid soap to pass from said reservoir through said adapter and into said brush.
