US 5,313,707 A · Watermelon seed remover

Abstract

A suitably dimensioned, hollow, crescent-shaped die with an upstanding handle provides a culinary tool for conveniently and quickly removing all the seeds from a watermelon. Upright side walls on the perimeter of the die engage each of the seed-bearing, crescent-shaped-in-section columns and extract the column as the die is withdrawn at the conclusion of the cutting portion of the cycle. By arranging a portion of the die and side walls in an overlapping relation, the areal extent of the die can be expanded, after withdrawal, to allow the attendant seed-bearing column to drop from the die by gravity. If desired, the overlapping portion can be augmented by slots and a pair of retainer pins to restrict the extent of change of the die area to a predetermined range; and inward shark tooth projections on the side walls can be used to enhance the ability of the side walls to lift the column during die withdrawal. A spring-loaded cross-tong attached to the side walls can serve not only as a handle but also as a die expander to release a seed-bearing column at the conclusion of the seed-removal cycle.

Dependent claims

A device for cutting and removing the crescent-shaped, seed-bearing column from the flesh of a sliced watermelon, said device comprising:

a. a hollow, crescent-shaped die having a cutting edge sized and configured to encompass the seed-bearing column as said die is urged into the watermelon flesh,
said die including side walls upstanding from said cutting edge for frictional engagement with the peripheral surface of the seed-bearing column to effect withdrawal of the column concurrently with the removal of said die,
said side walls in at least one portion of the perimeter of said side walls being in overlapping and relatively slidable relation in order to contract and enlarge the areal extent of said die between a respective first contracted position in which said side walls engage the seed-bearing column and a second enlarged position in which the seed-bearing column is released from said side walls,
said side walls being of spring-steel-like material and in which the spring force urges said side walls toward said first contracted position;
b. a handle including means for opposing the spring force exerted by said side walls and means for urging said side walls toward said second enlarged position;
and,
c. means for mounting said handle on said die for holding and urging said die into the watermelon flesh in congruent relation with the seed-bearing column.

b. a handle comprising a crossed-tong having a pair of pivoted upper arms, spring means for urging said upper arms toward distended attitude, an arm crossover portion, and a pair of lower arms mounted on said side walls in opposed relation and removed from the overlapped portion of said side walls, said spring means being effective to urge said lower arms and said overlapping portion of said side walls toward said first contracted position of said side walls;
and,
c. means for mounting said handle on said die for holding and urging said die into the watermelon flesh in congruent relation with the seed-bearing column.
