Abstract
Abstract A washing and scrubbing utensil has a hollow elongated handle having a back longitudinal end provided with a cap and an opposite front longitudinal end formed with a central longitudinally forwardly projecting feed tube communicating with the interior of the handle and with two longitudinally forwardly projecting holding spikes each having opposite edges formed with sawteeth. A sponge is fitted to the front end with the spikes and feed tube imbedded in the sponge and the sawteeth of the spikes poking into the sponge. The spikes are generally flat and lie generally in a common plane with the teeth of each spike projecting oppositely in the plane, the sponge being formed with respective slits receiving the spikes and extending generally perpendicular to the plane thereof. The sponge is formed with a further such slit between the slits of the spikes and receiving the feed tube. This slit is of substantially the same longitudinal length as the feed tube and is of a width equal generally to half of the circumference of the feed tube.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
114 words
A washing and scrubbing utensil comprising: a hollow elongated handle having a back longitudinal end, an opposite front longitudinal end and an interior; a cap on said back longitudinal end; two longitudinally forwardly projecting holding spikes on said front longitudinal end and each having opposite edges formed with sawteeth; a central longitudinally forwardly projecting feed tube also on said front longitudinal end and communicating with said interior of said handle; and a sponge fitted to said front end with said holding spikes and feed tube imbedded in said sponge and said sawteeth of said holding spikes poking into said sponge, said spikes, feed tube and handle being unitary and together forming a one-piece element.
Claim 2
Dependent Claim
114 words
A washing and scrubbing utensil comprising: a hollow elongated handle having a back longitudinal end, an opposite front longitudinal end and an interior; a cap on said back longitudinal end; two longitudinally forwardly projecting holding spikes on said front longitudinal end and each having opposite edges formed with sawteeth; a central longitudinally forwardly projecting feed tube also on said front longitudinal end and communicating with said interior of said handle; and a sponge fitted to said front end with said holding spikes and feed tube imbedded in said sponge and said sawteeth of said holding spikes poking into said sponge, said spikes, feed tube and handle being unitary and together forming a one-piece element.
Claim 3
Dependent Claim
51 words
The washing and scrubbing utensil defined in claim 1 wherein the spikes are generally flat and lie generally in a common plane with the teeth of each spike projecting oppositely in the plane, the sponge being formed with respective slits receiving the spikes and extending generally perpendicular to the plane thereof.
Claim 4
Dependent Claim
30 words
The washing and scrubbing utensil defined in claim 2 wherein the sponge is formed with a further such slit between the slits of the spikes and receiving the feed tube.
Claim 5
Dependent Claim
40 words
The washing and scrubbing utensil defined in claim 3 wherein the further slit is of substantially the same longitudinal length as the feed tube and is of a width equal generally to half of the circumference of the feed tube.
Claim 6
Dependent Claim
45 words
The washing and scrubbing utensil defined in claim 2 wherein the spike slits are of substantially the same longitudinal length as the spikes and of a width measured transverse to the plane that is substantially equal to the width of the spikes in the plane.
Claim 7
Dependent Claim
22 words
The washing and scrubbing utensil defined in claim 1 wherein feed tube has a longitudinally forward tip generally centered in the sponge.
Claim 8
Dependent Claim
22 words
The washing and scrubbing utensil defined in claim 1 wherein the spikes are formed with longitudinally extending and forwardly tapered stiffening ribs.
Claim 9
Dependent Claim
25 words
The washing and scrubbing utensil defined in claim 1 wherein said one-piece element including said spikes, feed tube, and handle is of a synthetic resin.
Claim 10
Dependent Claim
20 words
The washing and scrubbing utensil defined in claim 1 wherein the sponge has one face provided with an abrasive overlay.
Claim 11
Dependent Claim
65 words
The washing and scrubbing utensil defined in claim 3 wherein the utensil is composed of two structures, said sponge with slits being the first structure and said unitary spikes, feed tube and handle being the second structure such that said first structure is mountable on second structure by fitting the former onto the latter with insertion of said spikes and feed tube into said slits.
Claim 12
Dependent Claim
166 words
A washing and scrubbing utensil comprising: a hollow elongated handle having a back longitudinal end, an opposite front longitudinal end and an interior; a cap on said back longitudinal end; two longitudinally forwardly projecting holding spikes on said front longitudinal end and each having opposite edges formed with sawteeth; a central longitudinally forwardly projecting feed tube also on said front longitudinal end and communicating with said interior of said handle; and a sponge fitted to said front end with said holding spikes and feed tube imbedded in said sponge and said sawteeth of said holding spikes poking into said sponge; said feed tube extending so that when said hollow handle is in a position resting on a horizontal surface and filled with a predetermined quantity of wash liquid, the liquid assumes, within said hollow handle, a horizontal upper surface which is below a highest point of said feed tube in said position, so as to prevent spilling of the wash liquid out of said feed tube.
Claim 13
