Abstract

An apple corer having four molded plastic components are fitted together to form the invention. They are a hollow cutting tube, a core remover slidable along the cutting tube, a handle attached at the end of the cutting tube, and a compression plug inserted at the same end for locking the handle in place. The tip of the cutting tube has serrated teeth for smooth boring into the apple. In operation, the handle is oscillated while applying pressure to it. This causes the cutting tube to bore through the apple. The tube is removed from the apple and the resulting core left in the tube is ejected by sliding the core remover towards the tip of the cutter. The corer can also be used for partial removal of the apple core when stuffed apples are desired. In this situation prongs are attached to the end of the core remover. The cutter is bored partially into the apple, the core remover is slid against the face of the apple causing the prongs to impale the apple and hold the core in place. The apple is twisted which causes the core to shear off at the tip of the cutter. The partial core in then removed as before.

Dependent claims

An apple corer comprising:

slotted cutting tube means having a bore for coring the apple;
a core remover for removing the core left in said bore;
said core remover further comprising a hollow cylinder and having a smaller concentric cylinder having a face placed axially within said hollow cylinder and held rigidly in position by a brace between said two cylinders thereby creating a C-shaped opening between said two cylinders for allowing said core remover to slide in a reciprocal fashion over said cutting tube means and having said connecting brace slideable in said slot of said tube means;
hande means attached to said cutting tube means for gripping the apple corer;
said handle means further comprising a hollow cylinder having an interior wall of sufficient diameter to slideably fit over the distal end of said cutting tube means, said handle means having a spline running longitudinally along said interior wall of said handle and mating with said slot for preventing rotation of said handle about the distal end of said cutting tube means, said handle means having an annular ring projecting from said interior wall for preventing said handle from sliding over said cutting tube means;
a compression plug having a cylindrical member with a cap at one end for insertion through said annular ring of said handle and into said bore at said distal end of said cutting tube means resulting in a frictional compression fit, said compression plug further having an annular groove on the proximal side of said cap for mating with said annular ring of said handle, and securing said handle and said plug to the distal end of said cutting tube means.
