Abstract
Abstract A combination scoop and plunger for corralling refuse in a kitchen sink and forcing it through the drain opening into the garbage disposal area, comprising a single molded plastic scoop and bellows arrangement, having within its hollow portion a hollow plunger whose neck portion is removably connected to the upper portion of the bellows and which may be provided with cleanser that can be dispensed therefrom. When the bellows are collapsed, the bottom portion of the plunger contacts the refuse, forcing it through the drain opening.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
336 words
A kitchen utensil for corralling refuse over a drain opening and forcing it through said opening, comprising a unitary outer hollow shell, a plunger extending longitudinally within said outer hollow shell and cap means for retaining the plunger in the shell, said shell including a lower hollow walled cavity of relatively large cross-sectional dimension and having a lowermost extremity for guiding refuse to said drain, the inner dimension of said shell at its lowermost extremity being larger than said drain opening thereby to define a refuse cavity, said shell further including an upper hollow walled cavity having an uppermost portion upon which said cap resides, said upper walled cavity being of smaller cross-sectional dimension than said lower cavity and having located in its walls means for collapsing and retracting said shell thereby to extend and retract said plunger, the upper and lower cavity being joined by an outwardly flaring wall, said plunger comprising a lowermost extremity compatible with, but of smaller dimension than said drain opening, an upper neck portion extending through and beyond said upper hollow walled cavity of said shell and being of lesser cross-sectional dimension than said upper cavity, and a lower bulb portion residing in said lower cavity of said shell and being of larger cross-sectional dimension than said upper cavity, said bulb portion being connected to said neck portion by an outwardly flaring wall extending adjacent to and below the outwardly flaring wall of said shell, said plunger being of sufficient length so that when the shell is fully retracted the lowermost extremity of said plunger is above the lowermost extremity of the shell and when the shell is collapsed, the lowermost extremity of said plunger extends beyond the lowermost extremity of the shell, said cap means being connected to that portion of said neck means which extends beyond said upper shell cavity and being of a larger cross-sectional dimension than said upper shell cavity, said cap means and said outwardly flaring walls co-operating to retain the plunger in the shell.
Claim 2

336 words
A kitchen utensil for corralling refuse over a drain opening and forcing it through said opening, comprising a unitary outer hollow shell, a plunger extending longitudinally within said outer hollow shell and cap means for retaining the plunger in the shell, said shell including a lower hollow walled cavity of relatively large cross-sectional dimension and having a lowermost extremity for guiding refuse to said drain, the inner dimension of said shell at its lowermost extremity being larger than said drain opening thereby to define a refuse cavity, said shell further including an upper hollow walled cavity having an uppermost portion upon which said cap resides, said upper walled cavity being of smaller cross-sectional dimension than said lower cavity and having located in its walls means for collapsing and retracting said shell thereby to extend and retract said plunger, the upper and lower cavity being joined by an outwardly flaring wall, said plunger comprising a lowermost extremity compatible with, but of smaller dimension than said drain opening, an upper neck portion extending through and beyond said upper hollow walled cavity of said shell and being of lesser cross-sectional dimension than said upper cavity, and a lower bulb portion residing in said lower cavity of said shell and being of larger cross-sectional dimension than said upper cavity, said bulb portion being connected to said neck portion by an outwardly flaring wall extending adjacent to and below the outwardly flaring wall of said shell, said plunger being of sufficient length so that when the shell is fully retracted the lowermost extremity of said plunger is above the lowermost extremity of the shell and when the shell is collapsed, the lowermost extremity of said plunger extends beyond the lowermost extremity of the shell, said cap means being connected to that portion of said neck means which extends beyond said upper shell cavity and being of a larger cross-sectional dimension than said upper shell cavity, said cap means and said outwardly flaring walls co-operating to retain the plunger in the shell.
Claim 3
Dependent Claim
13 words
A kitchen utensil, according to claim 1, wherein the plunger is substantially hollow.
Claim 4
Dependent Claim
20 words
A kitchen utensil, according to claim 2, wherein said cap is twistably removable from the neck portion of the plunger.
Claim 5
Dependent Claim
14 words
A kitchen utensil, according to claim 1, which is substantially circular in cross-sectional shape.
Claim 6
Dependent Claim
382 words
A kitchen utensil for corralling refuse over a drain opening and forcing it through said opening, comprising a unitary outer hollow shell, a plunger hollow extending longitudinally within said outer hollow shell and means for retaining the plunger in said shell, said shell including a lower extremity comprised of a means for guiding refuse to said drain, the inner dimension of said shell at its lower extremity being larger than said drain opening thereby to define a refuse cavity, said shell further including an upper extremity and located intermediate the upper and lower extremities a shell portion comprising means for collapsing and retracting said shell longitudinally thereby to extend and retract said plunger, said plunger being of sufficient length so that when the shell is fully retracted the lowermost extremity of said plunger is above the lower extremity of the shell and when the shell is collapsed said plunger extends beyond the lowermost extremity of the shell, said plunger comprising a lower portion having a dimension compatible with but of smaller dimension than said drain opening, said lower portion being a hollow bulb defining a bulb chamber normally located in an upper portion of the refuse cavity and an upper longitudinally extending hollow neck portion defining a neck chamber located in the shell portion comprising said collapsing and retracting means, said bulb chamber being in communication with said neck chamber and wherein the means for retaining the plunger in said shell comprises a cap connected to the upper end of the neck portion of the plunger and adjacent the upper extremity of the shell, the cap being of a cross-section similar to, but of a larger dimension than the upper end of the neck portion of the plunger, and wherein said cap is rotatable about the plunger neck portion, the upper end of the plunger neck portion is sealed by a membrane having a dispensing hole extending therethrough, and the cap is provided with a hole extending therethrough which, upon rotation of the cap, may be brought into and out of alignment with the dispensing hole of said membrane, such that when said holes are aligned, there is formed a dispensing conduit in communication with the neck chamber, and such that when said holes are not aligned, the neck chamber is sealed.
