Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 352 words
A canape maker comprising the combination: a hollow tubular body having an open forward end and a closed rear end and a bore therein, a tapered cutting edge on the exterior of the body at the forward end by tapering the exterior surface of the body forwardly into the inside surface of the body to prevent cut food from jamming the canape maker during use; a piston slidably mounted within the bore, the piston having a finger actuated stem extending through the closed end, a handle attached to the stem for moving the piston longitudinally within the hollow body, and the piston having a central aperture extending therein; whereby the forward end of the tubular body is adapted to cut layers for purposes of making a canape during which cutting operation the piston is moved rearwardly within the bore, whereupon when the desired number of layers constituting the canape are within the bore, a toothpick or the like is adapted to be inserted through these layers in the bore into the aperture in the piston to assure retention of all of the layers of the canape as a unit when the canape together with the toothpick is removed from the bore by pushing the piston forwardly towards the open end; the rear closed end of the tubular body including means for facilitating the disassembly of the piston from the tubular body for cleaning purposes, the disassembly means including a cap having a bore therethrough for extending across the rear end of the tubular body to form the closed end, the stem of the piston extending through the cap bore and being slidable therein with the piston, stem and handle being attached to the cap in a manner to prevent disassembly therefrom; and the interior of the tubular body defining the bore being tapered uniformly with increased diameter from the forward end to the rear end to permit slight radial expansion of the layers after cutting and after being moved rearwardly within the bore and the cut layers of the canape collected in the body will not emerge without urging of the piston.
Claim 2
Dependent Claim 352 words
A canape maker comprising the combination: a hollow tubular body having an open forward end and a closed rear end and a bore therein, a tapered cutting edge on the exterior of the body at the forward end by tapering the exterior surface of the body forwardly into the inside surface of the body to prevent cut food from jamming the canape maker during use; a piston slidably mounted within the bore, the piston having a finger actuated stem extending through the closed end, a handle attached to the stem for moving the piston longitudinally within the hollow body, and the piston having a central aperture extending therein; whereby the forward end of the tubular body is adapted to cut layers for purposes of making a canape during which cutting operation the piston is moved rearwardly within the bore, whereupon when the desired number of layers constituting the canape are within the bore, a toothpick or the like is adapted to be inserted through these layers in the bore into the aperture in the piston to assure retention of all of the layers of the canape as a unit when the canape together with the toothpick is removed from the bore by pushing the piston forwardly towards the open end; the rear closed end of the tubular body including means for facilitating the disassembly of the piston from the tubular body for cleaning purposes, the disassembly means including a cap having a bore therethrough for extending across the rear end of the tubular body to form the closed end, the stem of the piston extending through the cap bore and being slidable therein with the piston, stem and handle being attached to the cap in a manner to prevent disassembly therefrom; and the interior of the tubular body defining the bore being tapered uniformly with increased diameter from the forward end to the rear end to permit slight radial expansion of the layers after cutting and after being moved rearwardly within the bore and the cut layers of the canape collected in the body will not emerge without urging of the piston.
Claim 3
Dependent Claim 82 words
The invention in accordance with claim 1, wherein the cap includes means for increasing the securement of the cap to the rear end of the hollow body, the securement means including a plurality of ribs extending outwardly from the cap, with the cap having a reduced boss disposed internally of the rear end of the hollow body and the ribs being disposed on the reduced boss for increasing the frictional engagement of the boss with the rear end of the hollow body.
Claim 4
Dependent Claim 15 words
The invention in accordance with claim 1, wherein the central aperture extends into the stem.
Claim 5
Dependent Claim 15 words
The invention in accordance with claim 1, wherein the tubular body is square in cross-section.
Claim 6
Dependent Claim 15 words
The invention in accordance with claim 1, wherein the tubular body is oval in cross-section.
Claim 7
Dependent Claim 24 words
The invention in accordance with claim 1, wherein the tubular body includes more than four sides to provide canapes having a corresponding peripheral shape.
