ABSTRACT:
A Jack-O-Lantern forming method for cutting facial feature openings (14) in a pumpkin (12). At least one pumpkin die element (26) having a closed contour sidewall element (32) is provided. The sidewall element (32) has a lower edge (36) adapted for contiguous interface with the pumpkin outer surface contour (16). Additionally, the pumpkin die element (26) has an upper edge (38) adapted to be impact loaded for displacing the pumpkin die element (26) through a wall (22) of the pumpkin (12). The die element (26) is impacted on the upper edge (38) and displaced through the wall (22) to provide a plug element which is removable and is contoured in the form of one of the facial feature openings (14). Through use of a number of differently contoured die elements (26), a wide variety of facial feature contour openings (14) may be provided in a minimal time reference frame.
